Fear And Loathing In Open-Source Clothing Design
by Lawrence D'Oliveiro 18 Dec '17

18 Dec '17

Seems the Valentina project, to create an open-source clothing design package, has split in two over the usual reason--disagreements among the project members <http://libregraphicsworld.org/blog/entry/valentina-seamly2d>. In that article, Alexandre Prokoudine tries to give an even-handed account of the saga, which can sometimes be quite difficult. The proprietary software in this field is extremely expensive--to the point where it becomes hard for clothing makers/designers to hire people who are familiar with using it. An alternative project, called SodaCAD <http://www.sodacad.org/>, takes a very different view: more direct control over the design (as I understand it), rather than trying to automatically fit a predefined design to given measurements, as Valentina does. It hasn’t seen much activity in over three years, though.

Undoing Data Anonymization Is Trivial
by Lawrence D'Oliveiro 18 Dec '17

18 Dec '17

Yet another demonstration <http://www.theregister.co.uk/2017/12/18/no_hack_needed_anonymisation_beaten…> of the seeming impossibility of publishing “anonymized” sets of personal data that cannot be traced back to specific individuals. The response of the Australian Government to a previous demonstration of such “de-anonymization” techniques was to seek laws to ban them.

Why Linux HDCP Isn't the End of the World
by Peter Reutemann 17 Dec '17

17 Dec '17

'"There is no reason for the open-source community to worry..." writes Daniel Stone, who heads the graphics team at open-source consultancy Collabora. mfilion quotes Collabora.com: Recently, Sean Paul from Google's ChromeOS team, submitted a patch series to enable HDCP support for the Intel display driver. HDCP is used to encrypt content over HDMI and DisplayPort links, which can only be decoded by trusted devices... However, if you already run your own code on a free device, HDCP is an irrelevance and does not reduce freedom in any way.... HDCP support is implemented almost entirely in the hardware. Rather than adding a mandatory encryption layer for content, the HDCP kernel support is dormant unless userspace explicitly requests an encrypted link. It then attempts to enable encryption in the hardware and informs userspace of the result. So there's the first out: if you don't want to use HDCP, then don't enable it! The kernel doesn't force anything on an unwilling userspace.... HDCP is only downstream facing: it allows your computer to trust that the device it has been plugged into is trusted by the HDCP certification authority, and nothing more. It does not reduce user freedom, or impose any additional limitations on device usage.' -- source: https://linux.slashdot.org/story/17/12/16/0320227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Net Neutrality Repeal --- What It Means For NZ
by Rowan Schischka 17 Dec '17

17 Dec '17

<https://list.waikato.ac.nz/pipermail/wlug/2017-December/015504.html> So you are agreeing with me that USA has a problem of poor competition? In NZ if my provider gives me crap access to certain services, I have options, but in many places in the US they do not. Net Neutrality rules did not increase competition in USA, and I do not see how dropping regulations in US will affect NZ's access. Just like Internet censorship from the department of internal affairs is optional, so will any media business arrangement with our ISPs. I can choose one that does it and I can choose one that does not.

Should Google Be Paying News Sites For Linking To Them?
by Lawrence D'Oliveiro 16 Dec '17

16 Dec '17

News agencies in Europe, particularly, have been claiming for a long while that Google has been unfairly profiting from linking to their articles (and quoting snippets from them). So they want Governments to force Google to pay a “link tax” <https://www.techdirt.com/articles/20171214/16352638814/european-new-agencie…>. The reality of such things is that, regardless of laws to the contrary, the money tends to flow from the ones benefiting to the ones providing the value (cf the “Payola” scandals in the US). Which explains what happened in Spain after it brought in its link-tax law <https://www.techdirt.com/articles/20150725/14510131761/study-spains-google-…>. Maybe the news agencies’ real complaint is that Google is such a massively profitable advertising company.

Net Neutrality Repeal --- What It Means For NZ
by Rowan Schischka 16 Dec '17

16 Dec '17

>Doesn?t mean we shouldn?t have network neutrality here, though. It just >means the abuses have not been quite as flagrant to date. The article is about ghost problems. In America, with or without net neutrality, providers abuse their market position. Every argument to keep the net neutrality rules comes back to poor competition in telco providers, which previous regulations did not address. The article correctly states that we will not see problems here because of Chrous' position but they incorrectly state we do not have links between media and ISP; Vodafone currently offers package deals https:// www.vodafone.co.nz/pass/ The internet is still working and there is no barrier to stop you or me to start a competing business. If a company like Duco or the rugby union did a deal with an ISP, I would want a deal that gives me uninterrupted live sports streaming, but it wont happen if the government thinks they need to regulate this.

<http://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=11960493>: "Since so many of the services we use online have been developed in America, what is bad for the internet there is bad for us all." But fortunately, Carter added, New Zealand didn't have the market problems that made network neutrality such a pressing issue in the US. Doesn’t mean we shouldn’t have network neutrality here, though. It just means the abuses have not been quite as flagrant to date.

Avast Launches Open-Source Decompiler For Machine Code
by Peter Reutemann 14 Dec '17

14 Dec '17

'To help with the reverse engineering of malware, Avast has released an open-source version of its machine-code decompiler, RetDec, that has been under development for over seven years. RetDec supports a variety of architectures aside from those used on traditional desktops including ARM, PIC32, PowerPC and MIPS. As Internet of Things devices proliferate throughout our homes and inside private businesses, being able to effectively analyze the code running on all of these new devices becomes a necessity to ensure security. In addition to the open-source version found on GitHub, RetDec is also being provided as a web service. Simply upload a supported executable or machine code and get a reasonably rebuilt version of the source code. It is not possible to retrieve the exact original code of any executable compiled to machine code but obtaining a working or almost working copy of equivalent code can greatly expedite the reverse engineering of software. For any curious developers out there, a REST API is also provided to allow third-party applications to use the decompilation service. A plugin for IDA disassembler is also available for those experienced with decompiling software.' -- source: https://news.slashdot.org/story/17/12/14/006237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

AT&T Versus Carterfone Revisited
by Lawrence D'Oliveiro 14 Dec '17

14 Dec '17

Or, it takes a certain amount of Government regulation to maintain a free market <https://arstechnica.com/tech-policy/2017/12/carterfone-40-years/>. I like the closing remarks: We do not begrudge the CEOs of these great corporations their legal positions. But they are, as Andrew Carnegie would put it, stewards of the system, not its owners. They are not there to tell us to Go Away. They are there to keep the system running while we discover it, use it, develop it, innovate it, game it, finesse it, and reinvent it to our heart's content. The great enterprise of telecommunications is no better than our right to participate in it as individuals.

AMD Is Open-Sourcing Their Official Vulkan Linux Driver
by Peter Reutemann 13 Dec '17

13 Dec '17

'While many of you have likely heard of the "RADV" open-source Vulkan driver, it's been a community-written driver up to this point in the absence of AMD's official, cross-platform Vulkan driver being open-source. That's now changed with AMD now open-sourcing their official Vulkan driver. The code drop is imminent and they are encouraging the use of it for quick support of new AMD hardware, access to the Radeon GPU Profiler, easy integration of AMD Vulkan extensions, and enabling third-party extensions. For now at least it does provide better Vulkan performance than RADV but the RADV developers have indicated they plan to continue development of their Mesa-based Vulkan driver.' -- source: https://news.slashdot.org/story/17/12/13/016211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

1998 attack that messes with sites’ secret crypto keys is back in a big way
by Peter Reutemann 12 Dec '17

12 Dec '17

'A surprisingly big number of top-name websites—Facebook and PayPal among them—recently tested positive for a critical, 19-year-old vulnerability that allowed attackers to decrypt encrypted data and sign communications using the sites' secret encryption key. The vulnerability in the transport layer security protocol for Web encryption was disclosed in 1998 when researcher Daniel Bleichenbacher found it in the TLS predecessor known as secure sockets layer. A flaw in the algorithm that handles RSA encryption keys responded to certain types of errors in a way that divulged potentially sensitive information. With enough specially formed queries, attackers could exploit the weakness in a way that allowed them to decrypt ciphertext even when they didn't have the secret decryption key. SSL architects responded by designing workarounds that suppressed the error messages rather than removing or rewriting the faulty RSA algorithm. Researchers call the class of crypto vulnerability an Oracle because it provides only "yes" or "no" answers that, over time, can reveal detailed information about the contents of encrypted data. The information allows hackers to carry out what's known as an "adaptive chosen-ciphertext attack."' -- source: https://arstechnica.com/information-technology/2017/12/a-worrying-number-of… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Should Service Providers Be Liable For Content?
by Lawrence D'Oliveiro 11 Dec '17

11 Dec '17

It is commonly accepted that ISPs should not generally be held liable for things done by their customers--or indeed, anybody else’s customers over their pipes. This is currently the case in Australia, for example. But should protections be extended to what we might describe as “secondary” service providers--such as social media sites like Facebook, and of course Google? Seems like Australia agrees the answer should be mostly “yes”, but not for those specific companies. Not sure how they are going to decide who is eligible for such legal protections and who is not. <https://www.techdirt.com/articles/20171207/09383538762/mpaa-wins-australia-…>

Intel's ME May Be Massively Infringing on Minix3's Free Software License
by Peter Reutemann 10 Dec '17

10 Dec '17

'Almost all Free Software licenses (BSD, MIT, GPL...) require some sort of legal notice (legal attribution) given to the recipient of the software, both when the software is distributed in source and in binary forms. The legal notice usually contains the copyright holder's name and the license text. This means that it's not possible to hide and keep secret the existence of Free Software that you have stuck into your product that you distribute. If you do so, then you are not complying with the Free Software license and you are committing a copyright infringement! This is exactly what Intel seems to have done with the Intel ME. The Minix3 operating system license requires a legal notice, but so far it seems like Intel has not given the necessary legal notices. (Probably because they want to keep the inside of the ME secret.) Thus not only is Minix3 the most installed OS on our recent x86 CPUs -- but it might also the most pirated OS on our recent x86 CPUs!' -- source: https://slashdot.org/story/17/12/09/0610203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The FCC Still Doesn’t Know How the Internet
by Peter Reutemann 10 Dec '17

10 Dec '17

'The EFF describes the FCC's official plan to kill net neutrality as "riddled with technical errors and factual inaccuracies," including, for example, a false distinction between "Internet access service" and "a distinct transmission service" which the EFF calls "utterly ridiculous and completely ungrounded from reality." "Besides not understanding how Internet access works, the FCC also has a troublingly limited knowledge of how the Domain Name System (DNS) works -- even though hundreds of engineers tried to explain it to them this past summer... As the FCC would have it, an Internet user actively expects their ISP to provide DNS to them." And in addition, "Like DNS, it treats caching as if it were some specialized service rather than an implementation detail and general-purpose computing technique." "There are at least two possible explanations for all of these misunderstandings and technical errors. One is that, as we've suggested, the FCC doesn't understand how the Internet works. The second is that it doesn't care, because its real goal is simply to cobble together some technical justification for its plan to kill net neutrality. A linchpin of that plan is to reclassify broadband as an 'information service,' (rather than a 'telecommunications service,' or common carrier) and the FCC needs to offer some basis for it. So, we fear, it's making one up, and hoping no one will notice." "We noticed," their editorial ends, urging Americans "to tell your lawmakers: Don't let the FCC sell the Internet out."' -- source: https://yro.slashdot.org/story/17/12/09/0545230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Canadian ISPs And Hollywood Agree On Plan To Make Themselves Judge, Jury and Website Executioner

Think it could happen here <https://www.techdirt.com/articles/20171205/03452738742/canadian-isps-hollyw…>? A bunch of Canadian ISPs, together with various entertainment groups, is submitting a plan to the Canadian Radio-television and Communications Commission (CRTC), which is the regulatory body for broadcasting and telecoms, to maintain a list of sites which will be blocked by the ISPs at the request of the entertainment groups. Is there any recourse, any review process, any independent oversight? Nope. Any prospect for, shall we say, “mission creep”? Oh boy, is there... The CRTC seems less than enthused. I like this comment from their spokesperson: “Our government supports an open internet where Canadians have the ability to access the content of their choice in accordance to Canadian laws,” Sasseville says. “While other parts of the world are focused on building walls, we’re focused on opening doors‎.”

Of course you can have either the ARM native performance and the long battery life, or you can have the Windows compatibility, but you are not going to get both at once. Prognosis: whenever either member of the Wintel symbiote has tried to step out on their own, the results have been uniformly disastrous. I expect this foray to be no different.

MacOS High Sierra Bug Allows Login As Root With No Password
by Peter Reutemann 04 Dec '17

04 Dec '17

'A trivial-to-exploit flaw in macOS High Sierra, aka macOS 10.13, allows users to gain admin rights, or log in as root, without a password. The security bug is triggered via the authentication dialog box in Apple's operating system, which prompts you for an administrator's username and password when you need to do stuff like configure privacy and network settings. If you type in "root" as the username, leave the password box blank, hit "enter" and then click on unlock a few times, the prompt disappears and, congrats, you now have admin rights. You can do this from the user login screen. The vulnerability effectively allows someone with physical access to the machine to log in, cause extra mischief, install malware, and so on. You should not leave your vulnerable Mac unattended until you can fix the problem. And while obviously this situation is not the end of the world -- it's certainly far from a remote hole or a disk decryption technique -- it's just really, really sad to see megabucks Apple drop the ball like this. Developer Lemi Orhan Ergan was the first to alert the world to the flaw. The Register notes: "If you have a root account enabled and a password for it set, the black password trick will not work. So, keep the account enabled and set a root password right now..."' -- source: https://it.slashdot.org/story/17/11/28/2135236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Full JTAG access to the ME would allow making permanent hidden changes to the machine.

Is Open Source Innovation Now All About Vendor On-Ramps?
by Peter Reutemann 03 Dec '17

03 Dec '17

'InfoWorld published an interesting essay from Matt Asay, former COO at Canonical (and an emeritus board member of the Open Source Initiative), about innovation from the big public cloud vendors, which "even when open-sourced, doesn't really help the community at large... All this innovation is available to buy; none of it is available to build. Not for mere mortals, anyway." Google in particular has figured out how to both open-source code in a useful way and make it pay. As Server Density CEO David Mytton has underlined, Google hopes to "standardize machine learning on a single framework and API," namely TensorFlow, then supplement it "with a service that can [manage] it all for you more efficiently and with less operational overhead," namely Google Cloud. By open-sourcing TensorFlow and backing it with machine-learning-heavy Google Cloud, Google has open-sourced a great on-ramp to future revenue. My question: why not do this with the rest of its code? The simple answer is "Because it's a lot of work." That is, Google could open-source everything tomorrow without any damage to its revenue, but the code itself would provide other providers and enterprises only limited ability to increase their revenue unless Google did all the necessary prep work to make it useful to mere mortals not running superhuman Google infrastructure. This is the trick that AWS, Microsoft, and Google are all racing to figure out today. Not open source, per se, because that's the easy table stakes. No, the AWS/Microsoft Azure/Google Cloud trio are figuring out how to turn their innovations into open source on-ramps to their proprietary services. Companies used to lock up their code to sell it. Today, it's the opposite: They need to open it up to make their ability to operate the code at scale more valuable. For them.' -- source: https://news.slashdot.org/story/17/12/02/0833217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Understanding the New Red Hat-IBM-Google-Facebook GPL Enforcement Announcement
by Peter Reutemann 03 Dec '17

03 Dec '17

'Bruce Perens co-founded the Open Source Initiative with Eric Raymond -- and he's also Slashdot reader #3872. Bruce Perens writes: Red Hat, IBM, Google, and Facebook announced that they would give infringers of their GPL software up to a 30-day hold-off period during which an accused infringer could cure a GPL violation after one was brought to their attention by the copyright holder, and a 60 day "statute of limitations" on an already-cured infringement when the copyright holder has never notified the infringer of the violation. In both cases, there would be no penalty: no damages, no fees, probably no lawsuit; for the infringer who promptly cures their infringement. Perens sees the move as "obviously inspired" by the kernel team's earlier announcement, and believes it's directed against one man who made 50 copyright infringement claims involving the Linux kernel "with intent to collect income rather than simply obtain compliance with the GPL license." Unfortunately, "as far as I can tell, it's Patrick McHardy's legal right to bring such claims regarding the copyrights which he owns, even if it doesn't fit Community Principles which nobody is actually compelled to follow."' -- source: https://linux.slashdot.org/story/17/12/02/2024240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Net Un-Neutrality ... For Real
by Lawrence D'Oliveiro 01 Dec '17

01 Dec '17

Some of those who have been following the net neutrality debate may remember a spoof poster that showed what might happen if ISPs were allowed to charge you differently, based on which sites you were allowed to visit. Well, in Spain, which has no laws against this sort of thing, a similar situation has actually happened: one ISP is selling you addons to a basic broadband cap based, not on the amount of extra data you want, but on what you want to use it for. Their “Vodafone Pass” product offers tiers like €3/month extra for a “Social Pass”, or €5/month for a “Music Pass”. <https://pplware.sapo.pt/informacao/vodafone-portugal-pacotes-smartnet/>, referenced from <https://www.techdirt.com/articles/20171030/12364538513/portugal-shows-inter…>

HyperCard, in case you didn’t know, was an application created by Apple Macintosh engineer Bill Atkinson for that platform in 1987, and it was always hard to describe exactly what it was for. But it allowed users to create their own applications, aka “stacks”, around a card-based paradigm. One of the commenters points out that the basic idea is still alive and well, in the form of LiveCode, which is available as a paid online service <https://livecode.com/> and also in the form of Free Software <https://github.com/livecode/>.

Internet-paralyzing Mirai botnet comes roaring back with new strain
by Peter Reutemann 29 Nov '17

'Mirai, the Internet-of-things malware that turns cameras, routers, and other household devices into potent distributed denial-of-service platforms, may be lying low, but it's certainly not dead. Last week, researchers identified a new outbreak that infected almost 100,000 devices in a matter of days. In September of last year, Mirai emerged as a force to be reckoned with when it played a key role in silencing one of the most intrepid sources of security news in then-record-setting DDoS attacks topping 620 gigabits per second. Within a few weeks, Mirai's developer published the source code, a feat that allowed relatively unsophisticated people to wage the same types of extraordinarily big assaults. The release almost immediately helped touch off a series of large-scale attacks. The most serious one degraded or completely took down Twitter, GitHub, the PlayStation network, and hundreds of other sites by targeting Dyn, a service that provided domain name services to the affected sites. Last week, researchers from China-based Netlab 360 say they spotted a new, publicly available Mirai variant. The changes allowed the malware to spread to networking devices made by ZyXEL Communications that could be remotely accessed over telnet using default passwords. One of the exploits was published on October 31. Over a span of 60 hours starting on November 22, the new Mirai strain was able to commandeer almost 100,000 devices. Virtually all of the infected devices used IP addresses local to Argentina, a possible indication the outbreak targeted customers of a regional service provider who were assigned unsecured modems.' -- source: https://arstechnica.com/information-technology/2017/11/internet-paralyzing-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

66 Percent of Popular Android Cryptocurrency Apps Don't Use Encryption
by Peter Reutemann 29 Nov '17

29 Nov '17

'High-Tech Bridge used its free mobile app analysis software, called Mobile X-Ray, to peek under the hood of the top 30 cryptocurrency apps in the Google Play store at three different popularity levels: apps with up to 100,000 downloads, up to 500,000 downloads, and apps with more than 500,000 downloads. So, a total of 90 apps altogether. Of the most popular apps, 94 percent used outdated encryption, 66 percent didn't use HTTPS to encrypt user information in transit, 44 percent used hard-coded default passwords (stored in plain text in the code), and overall 94 percent of the most popular apps were found to have "at least three medium-risk vulnerabilities."' -- source: https://it.slashdot.org/story/17/11/29/1610245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bigger Drives, Bigger Buffers
by Lawrence D'Oliveiro 29 Nov '17

29 Nov '17

What caught my eye about this <http://www.theregister.co.uk/2017/11/28/toshiba_10tb_surveillance_drive/> was But the new drives have a doubled buffer, at 256MiB, ... Why should hard drives have large “buffers” in them at all? Their job is to read and write the data specified to them by the OS driver, no more and no less. Bigger buffers increase latency, and 256MiB seems absolutely massive and unnecessary. And then there’s the issue where the drive tells the OS that the data has been written, but in fact it is still sitting in a memory buffer. So it could still be lost if a power outage happens in the next few milliseconds. Telling lies like this seems to be all about looking good in benchmarks, and to hell with safeguarding data integrity.

Ubuntu 17.10: Return of the GNOME
by Peter Reutemann 27 Nov '17

27 Nov '17

'If you've been following the Linux world at all, you know this has been an entire year for spring cleaning. Early in 2017, Canonical stopped work on its homegrown Unity desktop, Mir display server, and its larger vision of "convergence"—a unified interface for Ubuntu for phones, tablets, and desktops. And now almost exactly six years after Ubuntu first switched from GNOME 2 to the Unity desktop, that has been dropped, too. The distro is back to GNOME, and Canonical recently released Ubuntu 17.10, a major update with some significant changes coming to the popular Ubuntu Linux operating system. In light of the GNOME switch, this release seems like more of a homecoming than an entirely new voyage. But that said, Ubuntu 17.10 simultaneously feels very much like the start of a new voyage for Ubuntu. The last few Ubuntu desktop releases have been about as exciting as OpenSSH releases—you know you need to update, but beyond that, no one really cares. Sure, there have been a few feature updates with each new numeric increment, perhaps some slightly more up-to-date GNOME and GTK components under the hood. But by and large, Ubuntu's Unity 7 desktop has been in maintenance mode for several years. That period of stagnation turned Ubuntu from one of the more interesting operating systems around into just another Linux distro barely worthy of mention. This trend changes with 17.10. There are big changes—an entirely new default desktop in fact—but this release feels different not because the desktop has changed, but because Ubuntu feels like it once again has a sense of focus and direction. Even Canonical's letter-based naming scheme has arrived at a starting over point: "Artful Aardvark" is 17.10's nickname.' -- source: https://arstechnica.com/gadgets/2017/11/ubuntu-17-10-return-of-the-gnome/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Clear Linux Beats CentOS, openSUSE, and Ubuntu in (Enterprise) Benchmark Tests
by Peter Reutemann 27 Nov '17

27 Nov '17

'Recently completed Linux distro benchmarks by Phoronix show Intel's Clear Linux is the most powerful on x86 hardware. A six-way, enterprise-focused Linux distro comparison show Clear Linux being the fastest with a Core i9 and Xeon systems, easily beating CentOS, openSUSE, and Ubuntu in a majority of the tests. When doing an 11-way Linux distro boot test they also found Clear Linux easily booted the fastest followed by the Clear-inspired Solus distribution. Clear Linux does work on AMD hardware and works on Intel CPUs back to Sandy Bridge but leverages its speed from optimized compiler settings, specially built libraries capable of AVX instructions on supported systems, a specially tuned kernel configuration, and other optimizations/patches. Debian 9.2 and Fedora 27 "ended up being dropped from this article due to data overload," the article concludes, "and those distributions really not offering anything really different in terms of the performance."' -- source: https://linux.slashdot.org/story/17/11/27/0227218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

There's A Cluster of 750 Raspberry Pi's at Los Alamos National Lab
by Peter Reutemann 26 Nov '17

26 Nov '17

'Slashdot reader overheardinpdx shares a video from the SC17 supercomputing conference where Bruce Tulloch from BitScope "describes a low-cost Rasberry Pi cluster that Los Alamos National Lab is using to simulate large-scale supercomputers." Slashdot reader mspohr describes them as "five rack-mount Bitscope Cluster Modules, each with 150 Raspberry Pi boards with integrated network switches." With each of the 750 chips packing four cores, it offers a 3,000-core highly parallelizable platform that emulates an ARM-based supercomputer, allowing researchers to test development code without requiring a power-hungry machine at significant cost to the taxpayer. The full 750-node cluster, running 2-3 W per processor, runs at 1000W idle, 3000W at typical and 4000W at peak (with the switches) and is substantially cheaper, if also computationally a lot slower. After development using the Pi clusters, frameworks can then be ported to the larger scale supercomputers available at Los Alamos National Lab, such as Trinity and Crossroads. BitScope's Tulloch points out the cluster is fully integrated with the network switching infrastructure at Los Alamos National Lab, and applauds the Raspberry Bi cluster as "affordable, scalable, highly parallel testbed for high-performance-computing system-software developers."' -- source: https://hardware.slashdot.org/story/17/11/25/051211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Four Microsoft Engineers Proved That The “Darknet” Would Defeat DRM
by Lawrence D'Oliveiro 24 Nov '17

24 Nov '17

A rerun of an article published five years ago, about a (in)famous paper from 2002 <https://arstechnica.com/tech-policy/2017/11/how-four-microsoft-engineers-pr…>: By itself, the paper's clever and provocative argument likely would have earned it a broad readership. But the really remarkable thing about the paper is who wrote it: four engineers at Microsoft whose work many expected to be at the foundation of Microsoft's future DRM schemes. The paper's lead author told Ars that the paper's pessimistic view of Hollywood's beloved copy protection schemes almost got him fired. But ten years later [2012], its predictions have proved impressively accurate. ... While Biddle and his colleagues didn't succeed in allaying the fears of Palladium's critics, the paper's central arguments have held up well. The authors predicted that the emergence of the darknet would produce a technological and legal arms race. They thought content companies and law enforcement would attack those aspects of the darknet that were most centralized, but that the darknet would adapt through greater decentralization. And they predicted that efforts to build secure DRM schemes would continue to fail. All of their predictions have continued to hold true over the last decade. And still continue to hold true.

Firefox Will Warn Users When Visiting Sites That Suffered a Data Breach
by Peter Reutemann 23 Nov '17

'Mozilla engineers are working on a notifications system for Firefox that shows a security warning to users visiting sites that have suffered data breaches. The notifications system will use data provided by Have I Been Pwned?, a website that indexes public data breaches and allows users to search and see if their details have been compromised in any of these incidents. Work on this project has only recently started. The code to show these warnings is not even in the Firefox codebase but managed separately as an add-on available (on GitHub). The alert also includes an input field. In the add-ons current version this field doesn't do anything, but we presume it's there to allow users to search and see if their data was exposed during that site's security breach.

Skype for Linux has been at V4.3 for quite some time (years?). This version has now gone end-of-life and Microsoft replaced it with Skype for Linux V8.10.0.4 on 8 November 2017. If you start Skype for Linux V4.3 it will launch the login screen. Upon entering your account and password details Skype will crash. You will not be the only one to have struck this feature and you can read about this here<https://askubuntu.com/questions/975804/skype-crashes-after-logging-in>. For an announcement on Skype for Linux from Microsoft and public discussion go here<https://answers.microsoft.com/en-us/skype/forum/skype_linux-skype_startms-s…> I used synaptic packet manager to remove my Skype 4.3. I then downloaded Skype V8.10 from here<https://www.skype.com/en/get-skype/> for my Ubuntu 16.04 laptop. The file downloaded was skypeforlinux-64.deb at 63.9MB. Double clicking on the file auto-launched its installation. I found that my preferred settings had changed so you may want to spend some time going through them and setting them as desired. >From the public discussion<https://answers.microsoft.com/en-us/skype/forum/skype_linux-skype_startms-s…> on this new version the 4th person to post a reply states... "with lots of improvements" Really? No more search in history. No more normal application settings. No more support of x32 processors. Enjoy the "improvements". cheers, Ian.

How a Wi-Fi Pineapple Can Steal Your Data (And How To Protect Yourself From It)
by Peter Reutemann 23 Nov '17

23 Nov '17

'The Wi-Fi Pineapple is a cheap modified wireless router enables anyone to execute sophisticated exploits on Wi-Fi networks with little to no networking expertise. A report in Motherboard explains how it can be used to run a Wall of Sheep and execute a man-in-the-middle attack, as well as how you can protect yourself from Pineapple exploits when you're connected to public Wi-Fi. "... it's important that whenever you are done connecting to a public Wi-Fi network that you configure your phone or computer to 'forget' that network. This way your device won't be constantly broadcasting the SSIDs of networks it has connected to in the past, which can be spoofed by an attacker with a Pineapple," reports Motherboard. "Unfortunately there is no easy way to do this on an Android or an iPhone, and each network must be forgotten manually in the 'Manage Network' tab of the phone's settings. Another simple solution is to turn off your Wi-Fi functionality when you're not using it -- though that isn't as easy to do on some devices anymore -- and don't allow your device to connect to automatically connect to open Wi-Fi net' -- source: https://yro.slashdot.org/story/17/11/21/2255254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google collects Android users’ locations even when location services are disabled
by Peter Reutemann 21 Nov '17

21 Nov '17

'Many people realize that smartphones track their locations. But what if you actively turn off location services, haven’t used any apps, and haven’t even inserted a carrier SIM card? Even if you take all of those precautions, phones running Android software gather data about your location and send it back to Google when they’re connected to the internet, a Quartz investigation has revealed. Since the beginning of 2017, Android phones have been collecting the addresses of nearby cellular towers—even when location services are disabled—and sending that data back to Google. The result is that Google, the unit of Alphabet behind Android, has access to data about individuals’ locations and their movements that go far beyond a reasonable consumer expectation of privacy.' -- source: https://qz.com/1131515/google-collects-android-users-locations-even-when-lo… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

No, you’re not being paranoid. Sites really are watching your every move
by Peter Reutemann 20 Nov '17

20 Nov '17

'If you have the uncomfortable sense someone is looking over your shoulder as you surf the Web, you're not being paranoid. A new study finds hundreds of sites—including microsoft.com, adobe.com, and godaddy.com—employ scripts that record visitors' keystrokes, mouse movements, and scrolling behavior in real time, even before the input is submitted or is later deleted. Session replay scripts are provided by third-party analytics services that are designed to help site operators better understand how visitors interact with their Web properties and identify specific pages that are confusing or broken. As their name implies, the scripts allow the operators to re-enact individual browsing sessions. Each click, input, and scroll can be recorded and later played back. A study published last week reported that 482 of the 50,000 most trafficked websites employ such scripts, usually with no clear disclosure. It's not always easy to detect sites that employ such scripts. The actual number is almost certainly much higher, particularly among sites outside the top 50,000 that were studied.' -- source: https://arstechnica.com/tech-policy/2017/11/an-alarming-number-of-sites-emp… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Technology groups and dealing with predators
by Bryce Utting 20 Nov '17

The Verge has a detailed (read: graphic) report of predatory behaviour from ex-Auckland security expert Morgan Marquis-Boire, late of Google and the Citizen Lab of the University of Toronto, with connections to the Freedom of the Press Foundation, the EFF, and presumably others. Content warning for sexual assault issues: https://www.theverge.com/2017/11/19/16675704/morgan-marquis-boire-hacker-se… I can only commend those who have come forward, and also Ron Deibert of Citizen Lab for his well-aimed response. Without opening old wounds, I'd suggest that the Citizen Lab code of conduct might be useful food for thought where public WLUG events are involved. (unless a code of conduct already exists and I missed it?) A separate incorporated society I'm involved in has had to deal with complaints of a predator at an event, and a similar document could have done wonders for laying out how to appropriately evaluate and respond in the absence of a police complaint.The Harvey Weinstein disclosures are making clear how endemic this behaviour is, and how rare appropriate responses are. butting

Intel Planning To End Legacy BIOS Support By 2020, Report Says
by Peter Reutemann 20 Nov '17

20 Nov '17

'Intel is planning to end "legacy BIOS" support in their new platforms by 2020 in requiring UEFI Class 3 or higher. Making rounds this weekend is a slide deck from the recent UEFI Plugfest. Brian Richardson of Intel talked about the "last mile" barriers to removing legacy BIOS support from systems. By 2020, they will be supporting no less than UEFI Class 3, which means only UEFI support and no more legacy BIOS or CSM compatibility support mode. But that's not going to force on UEFI Secure Boot unconditionally: Secure Boot enabled is considered UEFI Class 3+. Intel hasn't removed legacy BIOS / CSM support yet due to many customers' software packages still relying upon legacy BIOS, among other reasons. Removing the legacy BIOS support will mitigate some security risks, needs less validation by vendors, allows for supporting more modern technologies, etc.' -- source: https://tech.slashdot.org/story/17/11/20/1251249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Another Tor Browser Feature Makes It Into Firefox: First-Party Isolation
by Peter Reutemann 20 Nov '17

20 Nov '17

'Unbeknown to most users, Mozilla added a privacy-enhancing feature to the Firefox browser over the summer that can help users block online advertisers from tracking them across the Internet. The feature is named First-Party Isolation (FPI) and was silently added to the Firefox browser in August, with the release of Firefox 55. FPI works by separating cookies on a per-domain basis. This is important because most online advertisers drop a cookie on the user's computer for each site the user visits and the advertisers loads an ad. With FPI enabled, the ad tracker won't be able to see all the cookies it dropped on that user's PC, but only the cookie created for the domain the user is currently viewing. This will force the ad tracker to create a new user profile for each site the user visits and the advertiser won't be able to aggregate these cookies and the user's browsing history into one big fat profile. This feature was first implemented in the Tor Browser, a privacy-focused fork of the Firefox browser managed by the Tor Project, where it is known as Cross-Origin Identifier Unlinkability. FPI was added to Firefox as part of the Tor Uplift project, an initiative to bolster the Firefox codebase with some of the Tor Browser's unique privacy-focused features. The feature is not enabled by default. Information on how to enable it is in the linked article.' -- source: https://news.slashdot.org/story/17/11/20/1713235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bluetooth Hack Affects 20 Million Amazon Echo, Google Home Devices
by Peter Reutemann 17 Nov '17

17 Nov '17

'In September, security researchers discovered eight vulnerabilities -- codenamed collectively as BlueBorne -- in the Bluetooth implementations used by over 5.3 billion devices. We have now learned that an estimated 20 million Amazon Echo and Google Home devices are also vulnerable to attacks leveraging the BlueBorne vulnerabilities. The Hacker News reports: Amazon Echo is affected by the following two vulnerabilities: a remote code execution vulnerability in the Linux kernel (CVE-2017-1000251); and an information disclosure flaw in the SDP server (CVE-2017-1000250). Since different Echo's variants use different operating systems, other Echo devices are affected by either the vulnerabilities found in Linux or Android. Whereas, Google Home devices are affected by one vulnerability: information disclosure vulnerability in Android's Bluetooth stack (CVE-2017-0785). This Android flaw can also be exploited to cause a denial-of-service (DoS) condition. Since Bluetooth cannot be disabled on either of the voice-activated personal assistants, attackers within the range of the affected device can easily launch an attack. The security firm [Armis, who disclosed the issue] notified both Amazon and Google about its findings, and both companies have released patches and issued automatic updates for the Amazon Echo and Google Home that fixes the BlueBorne attacks.

Just the latest <https://arstechnica.com/gaming/2017/11/russian-military-cites-game-screensh…> in an ever-growing line of incidents where various Governments and Press agencies mistakenly cite video-game footage as “proof” of nefarious activities by their opponents, and end up with egg on their faces as a result. Part of the trouble seems to be that such images tend to rank very highly in Google searches. But that shouldn’t be much of an obstacle for *proper* researchers, right? ;)

oldest usable Android version -- any opinions?
by Ian Young 15 Nov '17

15 Nov '17

Apologies for straying off topic. I need to get an Android phone to replace an ancient Sony-E, but hanker somewhat for the days of removable batteries, and like a stylus. This points afaict to an older Samsung Note model but then comes the problem of obsolete versions of Android. Can anyone suggest what is the oldest Android that can still be used on the web of today? Or perhaps there is a current phone with removable battery? ~ Ian Y

OnePlus Phones Come Preinstalled With a Factory App That Can Root Devices
by Peter Reutemann 14 Nov '17

14 Nov '17

'Some OnePlus devices, if not all, come preinstalled with an application named EngineerMode that can be used to root the device and may be converted into a fully-fledged backdoor by clever attackers. The app was discovered by a mobile security researcher who goes online by the pseudonym of Elliot Alderson -- the name of the main character in the Mr. Robot TV series. Speaking to Bleeping Computer, the researcher said he started investigating OnePlus devices after a story he saw online last month detailing a hidden stream of telemetry data sent by OnePlus devices to the company's servers.' -- source: https://yro.slashdot.org/story/17/11/14/140250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A History Of The Amiga, Part 11
by Lawrence D'Oliveiro 14 Nov '17

14 Nov '17

<https://arstechnica.com/gaming/2017/11/a-history-of-the-amiga-part-11-betwe…>: Then came an announcement that caused an uproar in the Amiga community; some even saw it as a betrayal. Jim Collas’ team revealed that it was switching the OS kernel for Amiga OE from QNX to Linux. ... In retrospect, this was probably the correct choice. Linux, then and now, supported a much more diverse array of hardware and was already gaining significant momentum in the tech industry. But Amiga fans didn’t see it that way at the time. They saw Linux as bloated, clunky, and slow, the exact opposite of their beloved Amiga. QNX Neutrino was seen as fast, small, and elegant, and the community had rallied behind it. This takes place in 1999. I did spend some time with Amiga fans about a decade earlier. Being a Mac fan at the time, I saw it as a bad move to tie to OS architecture so closely to particular quirks of the hardware. And sure enough, that did cause compatibility problems for Amiga software on later hardware.

How to Install Firefox Quantum in Ubuntu Right Now
by Peter Reutemann 12 Nov '17

12 Nov '17

'The upcoming version of Mozilla’s web browser Firefox is called Quantum because it’s blazing fast. It has been coded in Rust instead of the usual C++ and it is the first web browser to utilize the power of a multi-core processor. There has been lots of buzz around Quantum release. It is touted as a game-changing release that will help Firefox gain its lost userbase to Google Chrome. Ideally, Firefox Quantum should be released this month. But since I wanted to test it, I thought of installing it before its official release.' -- source: https://itsfoss.com/firefox-quantum-ubuntu/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Private Browsing Google Trouble
by Lawrence D'Oliveiro 12 Nov '17

12 Nov '17

Just tried to open a few Private Browsing sessions to do searches in Google in Firefox. Previously this has worked fine. But currently the connections are taking forever to complete. Explicitly connecting to google.com (instead of typing directly in the search box) has the same problem. Doing one of the same searches in a non-private tab worked fine. To compare, I connected to bing.com in a private tab, and did another of the searches there. Again, it worked fine.

New To Me: Game Asset Rippers
by Lawrence D'Oliveiro 12 Nov '17

12 Nov '17

While browsing around DeviantArt (as you do), I discovered this group <https://xnalaramodelandtuts.deviantart.com/>. The name “XNALara” comes from an open-source Windows program that let you create your own scenes and poses with assets (characters, props, scenery) from the “Tomb Raider: Underworld” game. (I think it has broadened its reach beyond that one game by now.) All very well, but how do you extract those assets from these games? Turns out there are these tools called “rippers”, which capture the OpenGL/DirectX drawing calls that the game makes and save all the geometry and textures and so on that are passed to those calls. (Did somebody say “copyright violation”?) Well, there are folders in that group that are absolutely full of these extracted assets. Some have been taken down on demand from the copyright owners, but the remarkable thing is that most of them are still available, and have been so for some years. And that the accounts of those uploading these collections have not been suspended. I tried loading one or two of them into Blender. There’s a range of formats, but one common combination is .obj+.mtl for the geometry and material definitions, and .dds for the texture images. The latter can be converted to PNG with ImageMagick and, after making corresponding edits to the references in the .mtl file, I was able to import the results and see something resembling the preview images. There have been artists on DeviantArt who have used these in their renders (and mentioned as much--that’s how I found out about them). I may try messing around with them a bit more, but I don’t think I’ll be publishing any such work...

But a new long-term study reveals that small media outlets have a far greater effect on public discussions than anyone realized. To be more precise, it only takes three or more stories from small news outlets covering the same topic to make discussions of that topic go up by 62.7 percent on Twitter.

3D Metal Printing At 100 Times The Speed And A Twentieth Of The Cost
by Lawrence D'Oliveiro 10 Nov '17

10 Nov '17

3D printing has mainly been confined to parts made out of various kinds of plastics up till now. Metal has been hard to deal with, because at some point you have to melt it, and that requires temperatures higher than any printing-type device could cope with. Now a company called “Desktop Metal” <http://www.theregister.co.uk/2017/11/10/metal_3d_printing_at_desktop_metal/> has come up with a scheme involving binding layers of metal powder, laid down in the right shape, using a temporary compound which is then removed when the part is melted in a furnace so it becomes a proper solid piece. Obviously this has to be done without losing its shape. The process can also do clever things like make a hinge, where there is no metal between the parts, so once the binding compound is removed, you have two solid parts that can freely rotate without falling apart.

MINIX: Intel's Hidden In-chip Operating System
by Peter Reutemann 09 Nov '17

09 Nov '17

'Matthew Garrett, the well-known Linux and security developer who works for Google, explained recently that, "Intel chipsets for some years have included a Management Engine [ME], a small microprocessor that runs independently of the main CPU and operating system. Various pieces of software run on the ME, ranging from code to handle media DRM to an implementation of a TPM. AMT [Active Management Technology] is another piece of software running on the ME." [...] At a presentation at Embedded Linux Conference Europe, Ronald Minnich, a Google software engineer reported that systems using Intel chips that have AMT, are running MINIX. So, what's it doing in Intel chips? A lot. These processors are running a closed-source variation of the open-source MINIX 3. We don't know exactly what version or how it's been modified since we don't have the source code. In addition, thanks to Minnich and his fellow researchers' work, MINIX is running on three separate x86 cores on modern chips. There, it's running: TCP/IP networking stacks (4 and 6), file systems, drivers (disk, net, USB, mouse), web servers. MINIX also has access to your passwords. It can also reimage your computer's firmware even if it's powered off. Let me repeat that. If your computer is "off" but still plugged in, MINIX can still potentially change your computer's fundamental settings. And, for even more fun, it "can implement self-modifying code that can persist across power cycles." So, if an exploit happens here, even if you unplug your server in one last desperate attempt to save it, the attack will still be there waiting for you when you plug it back in. How? MINIX can do all this because it runs at a fundamentally lower level. [...] According to Minnich, "there are big giant holes that people can drive exploits through." He continued, "Are you scared yet? If you're not scared yet, maybe I didn't explain it very well, because I sure am scared." Also read: Andrew S. Tanenbaum's (a professor of Computer Science at Vrije Universiteit) open letter to Intel' -- source: https://tech.slashdot.org/story/17/11/07/1041236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bruce Schneier On The Equifax Breach
by Lawrence D'Oliveiro 08 Nov '17

08 Nov '17

Security expert Bruce Schneier has published <https://www.schneier.com/blog/archives/2017/11/me_on_the_equif.html> the testimony he gave to the US House Energy and Commerce Committee on the breach of confidential personal information on close to half the entire population of the US. His main points are worth summarizing: 1. The Equifax breach was a serious security breach that puts millions of Americans at risk. 2. Equifax was solely at fault. 3. There are thousands of data brokers with similarly intimate information, similarly at risk. 4. These data brokers deliberately hide their actions, and make it difficult for consumers to learn about or control their data. 5. The existing regulatory structure is inadequate. 6. The market cannot fix this because we are not the customers of data brokers. 7. We need effective regulation of data brokers. 8. Resist complaints from the industry that this is "too hard." 9. This has foreign trade implications. 10. This has national security implications. 11. We need to do something about it. Read the article for more detail. I would say this is more than a US-specific problem, it is a worldwide problem. Other places may have stricter privacy regulations, but that might not be enough.

Linux Has a USB Driver Security Problem
by Peter Reutemann 08 Nov '17

08 Nov '17

'USB drivers included in the Linux kernel are rife with security flaws that in some cases can be exploited to run untrusted code and take over users' computers. The vast majority of these vulnerabilities came to light on Monday, when Google security expert Andrey Konovalov informed the Linux community of 14 vulnerabilities he found in the Linux kernel USB subsystem. "All of them can be triggered with a crafted malicious USB device in case an attacker has physical access to the machine," Konovalov said. The 14 flaws are actually part of a larger list of 79 flaws Konovalov found in Linux kernel USB drivers during the past months. Not all of these 79 vulnerabilities have been reported, let alone patched. Most are simple DoS (Denial of Service) bugs that freeze or restart the OS, but some allow attackers to elevate privileges and execute malicious code.' -- source: https://linux.slashdot.org/story/17/11/08/1730210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Create & manage docker hosts with Docker Machine on VirtualBox
by Peter Reutemann 08 Nov '17

'Docker Machine is a tool that let us install Docker Engine on virtual hosts on various platforms, on local environment as well on cloud. With Docker Machine, we can easily install docker hosts a Windows machine, a MAC machine or on cloud platform like AWS, AZURE etc. As we know that Docker Engine runs natively on Linux machines, so its pretty easy to get Docker working on Linux machines but for other OS like MAC or Windows this was a problem. So Docker Machine was introduced, especially for older versions of MAC & Windows (there are new native Docker apps for latest OS). Not meant only for Windows or MAC, Docker machine also provides efficient way to provision multiple Docker hosts on local as well as cloud network. To manage the docker hosts, we use rather than using ‘docker’ command, which is used with docker engine.

"Our research shows that a 'basic,' functional office suite, which is streamlined with a 'simple' and uncluttered, uncomplicated UI, serves an incredible under-represented community. "Other office suites are focusing on the 'power user' which is a valuable market, for sure, but the real power and range for an open-source office suite alternative is the vast majority which is the 'rest of us.

No, the Linux Desktop Hasn't Jumped in Popularity
by Peter Reutemann 06 Nov '17

06 Nov '17

'Stories have been circulating that the Linux desktop had jumped in popularity and was used more than macOS. Alas, it's not so... These reports have been based on NetMarketShare's desktop operating system analysis, which showed Linux leaping from 2.5 percent in July, to almost 5 percent in September. But unfortunately for Linux fans, it's not true... It seems to be merely a mistake. Vince Vizzaccaro, NetMarketShare's executive marketing share of marketing told me, "The Linux share being reported is not correct. We are aware of the issue and are currently looking into it"... For the most accurate, albeit US-centric operating system and browser numbers, I prefer to use data from the federal government's Digital Analytics Program (DAP). Unlike the others, DAP's numbers come from billions of visits over the past 90 days to over 400 US executive branch government domains... DAP gets its raw data from a Google Analytics account. DAP has open-sourced the code, which displays the data on the web and its data-collection code... In the US Analytics site, which summarizes DAP's data, you will find desktop Linux, as usual, hanging out in "other" at 1.5 percent. Windows, as always, is on top with 45.9 percent, followed by Apple iOS, at 25.5 percent, Android at 18.6 percent, and macOS at 8.5 percent. The article does, however, acknowledge that Linux's real market share is probably a little higher simply because "no one, not even DAP, seems to do a good job of pulling out the Linux-based Chrome OS data' -- source: https://linux.slashdot.org/story/17/11/05/202232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Walkthrough Of The Windows Subsystem For Linux
by Lawrence D'Oliveiro 05 Nov '17

05 Nov '17

Here <https://www.youtube.com/watch?v=VSqAyOY5huQ> is a nice intro to the Linux compatibility layer that Microsoft has added to Windows 10. Their app store gives you a choice of Ubuntu or two flavours of SuSE. But while these omit any X server functionality, they do include all the GUI X clients. So it is perfectly possible to install a Windows-native X server, such as the open-source VcXsrv <https://sourceforge.net/projects/vcxsrv/>. And then he uses this to demonstrate running a full XFCE desktop side-by-side with the regular Windows desktop.

Mozilla Might Distrust Dutch Government Certs Over 'False Keys'
by Peter Reutemann 05 Nov '17

05 Nov '17

'Mozilla engineers are discussing plans to remove support for a state-operated Dutch TLS/HTTPS provider after the Dutch government has voted a new law that grants local authorities the power to intercept Internet communications using "false keys". If the plan is approved, Firefox will not trust certificates issued by the Staat der Nederlanden (State of the Netherlands) Certificate Authority (CA)... This new law gives Dutch authorities the powers to intercept and analyze Internet traffic. While other countries have similar laws, what makes this one special is that authorities will have authorization to carry out covert technical attacks to access encrypted traffic. Such covert technical capabilities include the use of "false keys," as mentioned in Article 45 1.b, a broad term that includes TLS certificates. "Fears arise of mass Dutch Internet surveillance," reads a subhead on the article, citing a bug report which notes, among other things, the potential for man-in-the-middle attacks and the fact that the Netherlands hosts a major internet transit point' -- source: https://tech.slashdot.org/story/17/11/05/1845240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OnionShare – A Tool To Share Any Size Of Files Securely And Anonymously
by Peter Reutemann 05 Nov '17

05 Nov '17

'When we wrote an article about file sharing utilities such as Magic Womhole & transfer.sh most of the users asked is it secure? and where the files are stored. So, we decided to bring one of the best utility that stores and share files securely over the Internet. When we dig on that, we came to know about OnionShare which fulfill all this requirements. How are you saying, it falls under this category? Yes, it’s true because most of us know about Tor Browser which allows users to browse securely, privately and anonymously by implementing Onion routing in the application layer. Onion routing is a technique for anonymous communication over a computer network. OnionShare also developed in the same manner and allows you to use the Tor network to send files anywhere in the world.' -- source: https://www.2daygeek.com/onionshare-secure-way-to-share-files-sharing-tool-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

TorMoil Vulnerability Leaks Real IP Address From Tor Browser Users; Security Update Released
by Peter Reutemann 04 Nov '17

04 Nov '17

'The Tor Project has released a security update for the Tor Browser on Mac and Linux to fix a vulnerability that leaks users' real IP addresses. The vulnerability was spotted by Filippo Cavallarin, CEO of We Are Segment, an Italian company specialized in cyber-security and ethical hacking. Cavallarin privately reported the issue -- which he codenamed TorMoil -- to the Tor Project last week. Tor Project developers worked with the Firefox team (Tor Browser is based on the Firefox browser) to release a fix. Today, the Tor team released version 7.0.9 to address the vulnerability. Tor Browser 7.0.9 is only available for Mac and Linux users. Tor Browser on Windows is not affected.' -- source: https://it.slashdot.org/story/17/11/03/2127235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Lots Of Digitally-Signed Malware Out There
by Lawrence D'Oliveiro 03 Nov '17

03 Nov '17

One of the security weaknesses exploited by the “Stuxnet” worm that sabotaged Iran’s nuclear enrichment program was that it had a valid digital signature from a recognized issuer of certificates for Windows software. Of course, the issuer would never knowingly have validated a piece of malware, but the certificate had been compromised so it could be used without their permission. Turns out this sort of thing is not only quite common, there is a further problem in that anti-malware software, which is supposed to pick up revoked certificates and reject signatures that use them, frequently has bugs in their implementation of the signature-checking protocol, so they can let these bad signatures through. <https://arstechnica.com/information-technology/2017/11/evasive-code-signed-…>

The Patent That Just Wouldn’t Die
by Lawrence D'Oliveiro 03 Nov '17

03 Nov '17

A holding company called Personal Audio claims to have a patent covering the entire idea of podcasting. Over the years, it has succeeded in winning some lucrative payouts, including $8 million from Apple and $1.3 million from CBS. All without making a single item of product itself. In other words, Personal Audio is what lawyers politely refer to as a “Non-Practising Entity” (NPE), or, in more common parlance, a patent troll. However, the Electronic Frontier Foundation has succeeded, with the help of a crowdfunding campaign, in invalidating this patent, using a system introduced at the USPTO called “inter partes review” (IPR). Of course, Personal Audio has not taken this lying down. It has come up with a truly imaginative series of legal counterarguments: * IPR violates the 7th Amendment of the US Constitution (right to trial by jury in a lawsuit). * IPR encourages “collective efforts to invalidate patents” which “severely tilts the playing field in favor of the party or parties seeking invalidation”. * the EFF has been working together with defendants in their litigation. Fortunately, the Court of Appeals for the Federal Circuit (CAFC) -- the same appeals court that overruled Judge William Alsup in his verdict (in Oracle vs Google) that APIs were not copyrightable -- seems to be a bit less uncritically pro-“Intellectual Property” these days (something to do with being slapped down by the Supreme Court?), and has rejected these arguments. Imagine if all this creativity had gone into producing actual useful products, instead of legal arguments ... <https://arstechnica.com/tech-policy/2017/11/eff-destroys-the-podcasting-pat…>

Microsoft Quietly Announces End of Last Free Windows 10 Upgrade Offer
by Peter Reutemann 03 Nov '17

03 Nov '17

'If you've been waiting to claim your free Windows 10 upgrade using the "assistive technologies" exception, you need to act soon. In a quiet change to an obscure web page, Microsoft announced this week that those exceptions will end on December 31, 2017. On July 29, 2016, Microsoft officially ended the Get Windows 10 program, which offered free Windows 10 upgrades to anyone currently running a supported earlier version of Windows. But the company left a giant loophole in a separate announcement at the same time. Under the terms of that announcement, individuals who use "assistive technologies" received an automatic extension of the free upgrade offer. Sometime in the past week, Microsoft quietly edited that page, to add "The accessibility upgrade offer expires on December 31, 2017."' -- source: https://tech.slashdot.org/story/17/11/03/1737219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Android Oreo Bug Sends Thousands of Phones Into Infinite Boot Loops
by Peter Reutemann 02 Nov '17

02 Nov '17

'A bug in the new "Adaptive Icons" feature introduced in Android Oreo has sent thousands of phones into infinite boot loops, forcing some users to reset their devices to factory settings, causing users to lose data along the way. The bug was discovered by Jcbsera, the developer of the Swipe for Facebook Android app (energy-efficient Facebook wrapper app), and does not affect Android Oreo (8.0) in its default state. The bug occurs only with apps that use adaptive icons -- a new feature introduced in Android Oreo that allows icons to change shape and size based on the device they're viewed on, or the type of launcher the user is using on his Android device. For example, adaptive icons will appear in square, rounded, or circle containers depending on the theme or launcher the user is using. The style of adaptive icons is defined a local XML file. The bug first manifested itself when the developer of the Swipe for Facebook Android app accidentally renamed the foreground image of his adaptive icon with the same name as this XML file (ic_launcher_main.png and ic_launcher_main.xml). This naming scheme sends Android Oreo in an infinite loop that regularly crashes the device. At one point, Android detects something is wrong and prompts the user to reset the device to factory settings. Users don't have to open an app, and the crashes still happen just by having an app with malformed adaptive icons artifacts on your phone. Google said it will fix the issue in Android Oreo 8.1.' -- source: https://tech.slashdot.org/story/17/11/01/1550256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Googler A Command Line Tool To Search Google
by Peter Reutemann 31 Oct '17

'Looking for information on the web has become something that we do day in and day out. Whether it is support you are looking for, looking for a product or news about a particular topic, all you have to do is search on the web. As a result, search engines have been designed so they can help us sift through or the garbage in order to get the information we seek. There are Google, Bing, and DuckDuckGo just to mention a few. But what do all these have in common, well, to use these you need a browser such as Firefox or Chromium first. Well does no problem at all; except when all you have is a terminal and no GUI and browser. Also, you may have a GUI and a browser but you wish you did not have to leave the terminal just for that quick search, and thus comes Googler.

How Kodi Took Over Piracy
by Peter Reutemann 30 Oct '17

30 Oct '17

'For years, piracy persisted mainly in the realm of torrents, with sites like The Pirate Bay and Demonoid connecting internet denizens to premium content gratis. But a confluence of factors have sent torrent usage plummeting from 23 percent of all North American daily internet traffic in 2011 to under 5 percent last year. Legal crackdowns shuttered prominent torrent sites. Paid alternatives like Netflix and Hulu made it easier just to pay up. And then there were the "fully loaded" Kodi boxes -- otherwise vanilla streaming devices that come with, or make easily accessible, so-called addons that seek out unlicensed content -- that deliver pirated movies and TV shows with push-button ease. "Kodi and the plugin system and the people who made these plugins have just dumbed down the process," says Dan Deeth, spokesperson for network-equipment company Sandvine. "It's easy for anyone to use. It's kind of set it and forget it. Like the Ron Popeil turkey roaster." Kodi itself is just a media player; the majority of addons aren't piracy focused, and lots of Kodi devices without illicit software plug-ins are utterly uncontroversial. Still, that Kodi has swallowed piracy may not surprise some of you; a full six percent of North American households have a Kodi device configured to access unlicensed content, according to a recent Sandvine study. But the story of how a popular, open-source media player called XBMC became a pirate's paradise might. And with a legal crackdown looming, the Kodi ecosystem's present may matter less than its uncertain future.' -- source: https://yro.slashdot.org/story/17/10/30/1931208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox To Get a Better Password Manager

'Mozilla engineers have started work on a project named Lockbox that they describe as "a work-in-progress extension [...] to improve upon Firefox's built-in password management." Mozilla released the new extension for employee-use only at first, but users can install it by going to this or this links. Lockbox revamps Firefox's antiquated password management utility with a new user interface (UI). A new Firefox UI button is also included, in case users want to add a shortcut in their browser's main interface to open Lockbox without going through all the menu options. Support for a master password is included, helping users secure their passwords from unauthorized access by co-workers, family members, or others.' -- source: https://news.slashdot.org/story/17/10/30/1245202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

If We Can’t Trust Kaspersky, Should We Trust Microsoft?

An opinion piece at Al Jazeera <http://www.aljazeera.com/indepth/opinion/trust-kaspersky-trust-microsoft-17…> considers: A single malicious update pushed from Microsoft could cripple almost every government worldwide. ... That a small number of vendors have the capacity to remotely shut down government infrastructure, or vacuum up secret documents, is almost too scary to wrap your head around. And that's without pondering how likely they are to be pressured by their governments. In the face of future conflict, is the first step going to be disabling auto-updates for software from that country?

Early HP Archives Destroyed
by Lawrence D'Oliveiro 30 Oct '17

30 Oct '17

Bill Hewlett and Dave Packard were the archetypal “two guys who started a business in a garage” from 1938. When the company they founded moved on to other things (computers, printers etc), the original test-equipment business they created was spun off as part of a company called Agilent, which in turn divested it as an outfit now known as Keysight. Now we hear that important historical paper archives from those early days, which were in the care of Keysight Technologies, have been lost in the recent deadly Santa Rosa wildfires. <http://www.theregister.co.uk/2017/10/29/hewlett_packard_history_lost_to_san…>

You don’t need to manually log in to the hosting sites and upload or share your files. Anypaste will pick the right hosting sites depends upon the type of the file you want to upload. To put this simply, photos will get uploaded to image hosting sites, videos to video sites, code to pastebins. Cool, yeah? Anypaste is completely free, open source and light-weight script and you can do everything from command line. You don’t need to depend on any heavy, memory-consuming GUI apps to upload and share files.' -- source: https://www.ostechnix.com/anypaste-share-upload-files-compatible-hosting-si… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
