TinyPilot KVM Over IP
by Lawrence D'Oliveiro 31 Jan '21

31 Jan '21

Just been watching this review <https://www.youtube.com/watch?v=CyEpshm16HY> of the TinyPilot KVM-over-IP box. It’s purchasable from the maker’s website for US$300-plus, which is a fraction of the price of most other KVM-over-IP products. It’s built around a Raspberry π 4, using the camera adapter for HDMI in (no use made of the GPIO connector at all). Of course this means it can only support a connection to a single server machine. The source code is on GitHub if you want to build that yourself. The base product offers insecure HTTP-only access; if you want HTTPS, you have to pay extra for the TinyPilot Pro software licence. For comparison, some reader comments mention an alternative “PiKVM” product -- has anyone heard of this?

CERN Gets Its Open Hardware Licence Approved By OSI
by Lawrence D'Oliveiro 31 Jan '21

31 Jan '21

CERN wanted to come up with the hardware equivalent of open-source software licences. Such licences don’t really work well with hardware, because they use terms (like “linking” and “system libraries”) that aren’t applicable to hardware. So they worked with the Open Source Initiative (the custodians of the Open Source Definition) to come up with a selection of three licences, allowing for a choice of strong copyleft (GPL-equivalent), weak copyleft (LGPL-equivalent, I guess) and no copyleft at all. It seems these licences could actually be used for a combination of both hardware and software. <https://www.theregister.com/2021/01/29/cern_ohl_approved/>

Cloning SSD's
by Ian Stewart 31 Jan '21

31 Jan '21

FWIW: My recent experiences with copying SSD's... I recently installed Ubuntu Mate from USB stick to a 120GB SSD. I then updated with all the latest patches. This took about 30 minutes. I then tailored my preferences of Firefox, Terminal, Pluma, etc. Created a Guest account. Installed the NZ dictionary, and added some applications. This took me another 30 minutes. I then needed to do this to 5 more computers. So, to prepare six computers would have taken me a total of about 6 hours. I considered using the utility "dd" to copy a clone of my master disk. Looking through stackoverflow<https://unix.stackexchange.com/questions/144172/full-dd-copy-from-hdd-to-hdd> I found the suggestion to use "cat". I.e. Boot Ubuntu from a USB stick and assuming sda is my master disk and sdb is the clone, then issue the command... $ sudo sh -c 'cat /dev/sda >/dev/sdb' I found this copying took about 15 minutes. However, it didn't give me any progress report during the copying sequence. I then... $ sudo apt install pv ...pv stands for "Pipe Viewer". For the next SSD drive to be cloned I issued the command... $ sudo sh -c 'pv /dev/sda >/dev/sdb' ...which then provided a progress bar that updated every second. With Samsung SSD 120GB drives I found the operation took 13 minutes 13 seconds with a transfer rate of 153MB/s. I later had built another master SSD on a Kingston 120GB SSD and cloned this to another Kingston 120GB SSD which took 10 minutes and had a transfer rate of 200MB/s. I found with the system still powered on, I could unplug the cloned SSD and plug in another blank SSD and start another cloning. Probably not a recommended practice. After booting the clone, I edited /etc/hostname to make each clone unique. Maybe there's something else I should change??? In summary, allowing for a bit of time to physically move the SSD's between machines, I was effectively completing the installation/updating/tailoring at a rate of three PC's an hour. I dunno if this was the right way or the best way, but, so far, the masters and all the clones seem to be working OK. cheers, Ian.

Intel Iris Xe Video Cards Now Shipping To OEMs: DG1 Lands In Desktops
by Peter Reutemann 29 Jan '21

29 Jan '21

'Ryan Smith, writing at AnandTech: Following plans first unveiled last year during the launch of their DG1 GPU, Intel sends word this morning that the first Iris Xe video cards have finally begun shipping to OEMs. Based on the DG1 discrete GPU that's already being used in Intel's Iris Xe MAX laptop accelerators, the Iris Xe family of video cards are their desktop counterpart, implementing the GPU on a traditional video card. Overall, with specifications almost identical to Xe MAX, Intel is similarly positioning these cards for the entry-level market, where they are being released as an OEM-only part. As a quick refresher, the DG1 GPU is based on the same Xe-LP graphics architecture as Tiger Lake's integrated GPU. In fact, in broad terms the DG1 can be thought of as a nearly 1-to-1 discrete version of that iGPU, containing the same 96 EUs and 128-bit LPDDR4X memory interface as Tiger Lake itself. Consequently, while DG1 is a big first step for Intel -- marking the launch of their first discrete GPU of the modern era -- the company is planning very modestly for this generation of parts. The first DG1 GPUs were shipped in the fall as part of Intel's Iris Xe MAX graphics solution for laptops. At the time, Intel also indicated that a desktop card for OEMs would also be coming in 2021, and now, right on schedule, those desktop cards have begun shipping out.' -- source: https://hardware.slashdot.org/story/21/01/28/1649204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ProtonMail, Threema, Tresorit and Tutanota Warn EU Lawmakers Over 'Anti-Encryption' Push
by Peter Reutemann 29 Jan '21

29 Jan '21

'Four European apps which secure user data via end-to-end encryption, ProtonMail, Threema, Tresorit and Tutanota, have issued a joint-statement warning over recent moves by EU institutions that they say are setting lawmakers on a dangerous path to backdooring encryption. From a report: Last month the EU Council passed a resolution on encryption that's riven with contradiction -- calling for "security through encryption and security despite encryption" -- which the four e2e app makers believe is a thinly veiled call to backdoor encryption. The European Commission has also talked about seeking "improved access" to encrypted information, writing in a wide-ranging counter-terrorism agenda also published in December that it will "work with Member States to identify possible legal, operational, and technical solutions for lawful access." Simultaneously, the Commission has said it will "promote an approach which both maintains the effectiveness of encryption in protecting privacy and security of communications, while providing an effective response to crime and terrorism." And it has made it clear there will be no 'one silver bullet' as regards the e2e encryption security 'challenge.' But such caveats are doing nothing to alleviate the concerns of e2e encrypted app makers -- who are convinced proposals from the Council of the EU, which is involved in adopting the bloc's laws (though the Commission usually drafts legislation), sums to an push toward backdoors. "While it's not explicitly stated in the resolution, it's widely understood that the proposal seeks to allow law enforcement access to encrypted platforms via backdoors," the four app makers write, going on to warn that such a move would fatally underline the security EU institutions also claim to want to maintain. "The resolution makes a fundamental misunderstanding: Encryption is an absolute, data is either encrypted or it isn't, users have privacy or they don't," they go on. "The desire to give law enforcement more tools to fight crime is obviously understandable. But the proposals are the digital equivalent of giving law enforcement a key to every citizen's home and might begin a slippery slope towards greater violations of personal privacy."' -- source: https://yro.slashdot.org/story/21/01/28/1724250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitLab Reshuffles Its Paid Subscription Plans, Drops Its Bronze/Starter Tier
by Peter Reutemann 28 Jan '21

28 Jan '21

'GitLab, the increasingly popular DevOps platform, today announced a major update to its subscription model. The company is doing away with its $4/month Bronze/Starter package. Current users will be able to renew one more time at the existing price or move to a higher tier (and receive a significant discount for the first three years after they do so). The company's free tier, it is worth noting, is not going away and GitLab argues that it includes "89% of the features in Bronze/Starter." To ease the pain, Bronze users will be able to renew their existing subscription before January 26, 2022 for an additional year at the existing price. They can also opt to move to the Premium tier at a discounted price for the next three years, starting at $6/user/month in Year 1, but that price then goes up to $9/user/month and $15/user/month in Year 2 and 3 respectively. For new users, the Bronze package is no longer available, starting now. With this change, GitLab now offers three tiers: Free, Premium and Ultimate (it's also doing away with the "Silver/Premium" and "Gold/Ultimate" naming). "The Bronze tier, we were selling at a loss," GitLab founder and CEO Sid Sijbrandij told TechCrunch. "We were just losing money every time we sold it -- just on hosting and support. To be a sustainable business, this was a move we had to make. It's a big transition for our customers but we want to make sure we're a sustainable company and we can keep investing."' -- source: https://tech.slashdot.org/story/21/01/27/215226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Reddit 1: Wall Street 0
by Lawrence D'Oliveiro 28 Jan '21

28 Jan '21

Something very peculiar happened last week: a group of small-time stock traders who hang out on Reddit took on a well-funded Wall Street money manager, and won. What happened was, a company called Melvin Capital took out a “short position” on shares in GameStop--that is, they put money on a bet that the stock value would go down. The Redditors (part of a subreddit called “wallstreetbets”) figured out that this position was vulnerable, and bet against it by buying up GameStop shares. This drove up the price, forcing Melvin to either put up or shut up--put up a bunch of money to back up their position, or give up and lose an even bigger bunch of money. In other words, Melvin was caught in a “short squeeze”, which drove it to the verge of bankruptcy. A good, clear intro to the whole story is here <https://arstechnica.com/gaming/2021/01/the-complete-morons-guide-to-gamesto…>.

10-year-old Sudo Bug Lets Linux Users Gain Root-Level Access
by Peter Reutemann 28 Jan '21

28 Jan '21

'A major vulnerability impacting a large chunk of the Linux ecosystem has been patched today in Sudo, an app that allows admins to delegate limited root access to other users. From a report: The vulnerability, which received a CVE identifier of CVE-2021-3156, but is more commonly known as "Baron Samedit," was discovered by security auditing firm Qualys two weeks ago and was patched earlier today with the release of Sudo v1.9.5p2. In a simple explanation provided by the Sudo team today, the Baron Samedit bug can be exploited by an attacker who has gained access to a low-privileged account to gain root access, even if the account isn't listed in /etc/sudoers -- a config file that controls which users are allowed access to su or sudo commands in the first place.' -- source: https://linux.slashdot.org/story/21/01/27/1820205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Browser Makers Launch New Project For Writing Documentation For Web APIs
by Peter Reutemann 26 Jan '21

26 Jan '21

'A coalition of tech companies announced today the launch of Open Web Docs, a new initiative to help write documentation for Web APIs, JavaScript, and other web tooling and platforms. From a report: The new project does not view itself as a replacement for MDN Web Docs, a website hosted by Mozilla, where all browser makers agreed to move the official Web API documentation back in October 2017, and stop developing their own, often diverging, documentation sites. Instead, in a press release and FAQ today, the Open Web Docs team said their role is to fund, coordinate, and contribute to MDN Docs going forward. The new initiative comes after Mozilla laid off 250 employees last summer, including many of its MDN Web Docs staff. Open Web Docs comes to fill this void and provide the labor force needed to continue updating the MDN Web Docs portal.' -- source: https://tech.slashdot.org/story/21/01/25/216208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hacker Leaks Data of 2.28 Million Dating Site Users
by Peter Reutemann 26 Jan '21

26 Jan '21

'ZDNet: A well-known hacker has leaked the details of more than 2.28 million users registered on MeetMindful.com, a dating website founded in 2014, ZDNet has learned this week from a security researcher. The dating site's data has been shared as a free download on a publicly accessible hacking forum known for its trade in hacked databases. The leaked data, a 1.2 GB file, appears to be a dump of the site's users database. The content of this file includes a wealth of information that users provided when they set up profiles on the MeetMindful site and mobile apps. Some of the most sensitive data points included in the file include: Real names; Email addresses; City, state, and ZIP details; Body details; Dating preferences; Marital status; Birth dates; Latitude and longitude; IP addresses; Bcrypt-hashed account passwords; Facebook user IDs; and Facebook authentication tokens. Messages exchanged by users were not included in the leaked file; however, this does not make the entire incident less sensitive. The data leak, which is still available for download, was released by a threat actor who goes by the name of ShinyHunters. They also were responsible for leaking the details of millions of users registered on Teespring.

When Adobe Stopped Flash Content, It Also Stopped A Chinese Railroad
by Peter Reutemann 25 Jan '21

25 Jan '21

'Jalopnik shares a story for our times: Adobe's Flash, the web browser plug-in that powered so very many crappy games, confusing interfaces, and animated icons of the early web like Homestar Runner is now finally gone, after a long, slow, protracted death. For most of us, this just means that some goofy webgame you searched for out of misplaced nostalgia will no longer run. For a select few in China, though, the death of Flash meant being late to work, because the city of Dalian in northern China was running their railroad system on it. Yes, a railroad, run on Flash, the same thing used to run "free online casinos" and knockoff Breakout games in mortgage re-fi ads... Hell, YouTube used to run on Flash until 2015. It wasn't all stupid little web games but, that said, I can't for the life of me fathom why anyone would want to run a freaking railroad network on it, with physical, multi-ton moving railcars full of human beings on it. So, when Adobe finally killed Flash-based content from running, this Tuesday Dalian's railroad network found itself ground to a halt for 20 hours. The railroad's technicians did get everything back up and running, but the way they did this is fascinating, too. They didn't switch the rail management system to some other, more modern codebase or software installation; instead, they installed a pirated version of Flash that was still operational. The knockoff version seems to be known as "Ghost Version." This, along with installing an older version of the Flash player to work with the knockoff Flash server setup, "solved" the problem, and the railroad was back up and running.' -- source: https://tech.slashdot.org/story/21/01/24/189207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome 88 Released, Removing Adobe Flash -- and FTP
by Peter Reutemann 24 Jan '21

24 Jan '21

'Google released Chrome 88 this week — and besides improving its dark mode support, they removed support for both Adobe Flash and FTP. PC World calls it "the end of two eras." The most noteworthy change in this update is what's not included. Chrome 88 lays Adobe Flash and the FTP protocol to rest. RIP circa-2000 Internet. Neither comes as a surprise, though it's poetic that they're being buried together. Adobe halted Flash Player downloads at the end of 2020, making good on a promise made years before, and began blocking Flash content altogether a couple weeks later. Removing Flash from Chrome 88 is just Google's way of flushing the toilet. On the other hand, FTP isn't dead, but it is now for Chrome users. The File Transport Protocol has helped users send files across the Internet for decades, but in an era of prolific cloud storage services and other sharing methods, its use has waned. Google started slowly disabling FTP support in Chrome 86, per ZDNet, and now you'll no longer be able to access FTP links in the browser. Look for standalone FTP software instead if you need it, such as FileZilla. That's not all. Mac users should be aware that Chrome 88 drops support for OS X 10.10 (OS X Yosemite). Yosemite released in 2014 and received its last update in 2017... But Google killing Flash and FTP might be the footnotes that hit old-school web users in the feels. Chrome 88 will also block non-encrypted downloads originating from an encrypted page, the article reports. And the Verge notes Chrome also offers less intrusive website permission requests (as an experimental feature enabled from chrome://flags/#permission-chip ), while Bleeping Computer describes Chrome 88's new experimental feature for searching through all your open tabs. And Chrome's blog points out some additional features under the hood: Chrome 88 will heavily throttle chained JavaScript timers for hidden pages in particular conditions. This will reduce CPU usage, which will also reduce battery usage. There are some edge cases where this will change behavior, but timers are often used where a different API would be more efficient, and more reliable.' -- source: https://slashdot.org/story/21/01/23/2018224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why AWS Is Forking Elasticsearch and Kibana
by Peter Reutemann 24 Jan '21

24 Jan '21

'Steven J. Vaughan-Nichols writes at ZDNet: When Elastic, makers of the open-source search and analytic engine Elasticsearch, went after Amazon Web Services (AWS) by changing its license from the open-source Apache 2.0-license ALv2) to the non-open-source friendly Server Side Public License, I predicted "we'd soon see AWS-sponsored Elasticsearch and Kibana forks." The next day, AWS tweeted it "will launch new forks of both Elasticsearch and Kibana based on the latest Apache 2.0 licensed codebases." Well, that didn't take long! In a blog post, AWS explained that since Elastic is no longer making its search and analytic engine Elasticsearch and its companion data visualization dashboard Kibana available as open source, AWS is taking action. "In order to ensure open source versions of both packages remain available and well supported, including in our own offerings, we are announcing today that AWS will step up to create and maintain an ALv2-licensed fork of open-source Elasticsearch and Kibana.... AWS brings years of experience working with these codebases, as well as making upstream code contributions to both Elasticsearch and Apache Lucene, the core search library that Elasticsearch is built on — with more than 230 Lucene contributions in 2020 alone... We're in this for the long haul, and will work in a way that fosters healthy and sustainable open source practices — including implementing shared project governance with a community of contributors..."

Brad Cox, Creator of Objective-C Programming Language, Dies At 76
by Peter Reutemann 24 Jan '21

24 Jan '21

'We have learned that Brad Cox, computer scientist known mostly for creating the Objective-C programming language with his business partner Tom Love, died on January 2, 2021 at his residence. He was 76. >From a Legacy.com post: Brad was born on May 2, 1944 in Fort Benning, Georgia, to the late Nancy Hinson Cox and Dewey McBride Cox of Lake City, South Carolina. Brad grew up on the family's dairy farm in South Carolina but found himself most interested in science. After graduating from Lake City High School, he received his Bachelor of Science Degree in Organic Chemistry and Mathematics from Furman University, and his Ph.D. from the Department of Mathematical Biology at the University of Chicago, and worked on an early form of neural networks. He soon found himself more interested in computers and got a job at International Telephone and Telegraph (ITT) and later joined Schlumbeger -- Doll Research Labs, and ultimately formed his own Connecticut startup, Productivity Products International (PPI) later named Stepstone. Among his first known software projects, he wrote a PDP-8 program for simulating clusters of neurons. He worked at the National Institutes of Health and Woods Hole Oceanographic Institute before moving into the software profession. Dr. Cox was an entrepreneur, having founded the Stepstone Company together with Tom Love for releasing the first Objective-C implementation. Stepstone hoped to sell "ICPaks" and Dr. Cox focused on building his ICPak libraries and hired a team to continue work on Objective-C, including Steve Naroff. The late Steve Jobs', NeXT, licensed the Objective-C language for it's new operating system, NEXTSTEP. NeXT eventually acquired Objective- C from Stepstone. Objective-C continued to be the primary programming language for writing software for Apple's OS X and iOS.

DDoSers are abusing Microsoft RDP to make attacks more powerful
by Peter Reutemann 24 Jan '21

24 Jan '21

'DDoS-for-hire services are abusing the Microsoft Remote Desktop Protocol to increase the firepower of distributed denial-of-service attacks that paralyze websites and other online services, a security firm said this week. Typically abbreviated as RDP, Remote Desktop Protocol is the underpinning for a Microsoft Windows feature that allows one device to log into another device over the Internet. RDP is mostly used by businesses to save employees the cost or hassle of having to be physically present when accessing a computer. As is typical with many authenticated systems, RDP responds to login requests with a much longer sequence of bits that establish a connection between the two parties. So-called booter/stresser services, which for a fee will bombard Internet addresses with enough data to take them offline, have recently embraced RDP as a means to amplify their attacks, security firm Netscout said. The amplification allows attackers with only modest resources to strengthen the size of the data they direct at targets. The technique works by bouncing a relatively small amount of data at the amplifying service, which in turn reflects a much larger amount of data at the final target. With an amplification factor of 85.9 to 1, 10 gigabytes-per-second of requests directed at an RDP server will deliver roughly 860Gbps to the target. “Observed attack sizes range from ~20 Gbps – ~750 Gbps,” Netscout researchers wrote. “As is routinely the case with newer DDoS attack vectors, it appears that after an initial period of employment by advanced attackers with access to bespoke DDoS attack infrastructure, RDP reflection/amplification has been weaponized and added to the arsenals of so-called booter/stresser DDoS-for-hire services, placing it within the reach of the general attacker population.”' -- source: https://arstechnica.com/information-technology/2021/01/ddosers-are-abusing-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How DNSpooq Attacks Could Poison DNS Cache Records
by Peter Reutemann 24 Jan '21

24 Jan '21

'Earlier this week security experts disclosed details on seven vulnerabilities impacting Dnsmasq, "a popular DNS software package that is commonly deployed in networking equipment, such as routers and access points," reports ZDNet. "The vulnerabilities tracked as DNSpooq, impact Dnsmasq, a DNS forwarding client for *NIX-based operating systems." Slashdot reader Joe2020 shared Help Net Security's quote from Shlomi Oberman, CEO and researcher at JSOF. "Some of the bigger users of Dnsmasq are Android/Google, Comcast, Cisco, Red Hat, Netgear, and Ubiquiti, but there are many more. All major Linux distributions offer Dnsmasq as a package, but some use it more than others, e.g., in OpenWRT it is used a lot, Red Hat use it as part of their virtualization platforms, Google uses it for Android hotspots (and maybe other things), while, for example Ubuntu just has it as an optional package." More from ZDNet: Dnsmasq is usually included inside the firmware of various networking devices to provide DNS forwarding capabilities by taking DNS requests made by local users, forwarding the request to an upstream DNS server, and then caching the results once they arrive, making the same results readily available for other clients without needing to make a new DNS query upstream. While their role seems banal and insignificant, they play a crucial role in accelerating internet speeds by avoiding recursive traffic... Today, the DNSpooq software has made its way in millions of devices sold worldwide [including] all sorts of networking gear like routers, access points, firewalls, and VPNs from companies like ZTE, Aruba, Redhat, Belden, Ubiquiti, D-Link, Huawei, Linksys, Zyxel, Juniper, Netgear, HPE, IBM, Siemens, Xiaomi, and others. The DNSpooq vulnerabilities, disclosed today by security experts from JSOF, are dangerous because they can be combined to poison DNS cache entries recorded by Dnsmasq servers. Poisoning DNS cache records is a big problem for network administrators because it allows attackers to redirect users to clones of legitimate websites... In total, seven DNSpooq vulnerabilities have been disclosed today. Four are buffer overflows in the Dnsmasq code that can lead to remote code execution scenarios, while the other three bugs allow DNS cache poisoning. On their own, the danger from each is limited, but researchers argue they can be combined to attack any device with older versions of the Dnsmasq software... The JSOF exec told ZDNet that his company has worked with both the Dnsmasq project author and multiple industry partners to make sure patches were made available to device vendors by Tuesday's public disclosure.' -- source: https://it.slashdot.org/story/21/01/23/0412253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Alphabet Shuts Down Loon Internet Balloon Company
by Peter Reutemann 23 Jan '21

23 Jan '21

'Google's parent firm, Alphabet, is done exploring the idea of using a fleet of balloons to beam high-speed internet in remote parts of the world. From a report: The firm said on Thursday evening that it was winding down Loon, a nine-year-old project and a two-and-a-half-year-old spin off firm, after failing to find a sustainable business model and partners for one of its most prominent moonshot projects. The demise of Loon, which assumed spotlight after the project helped restore cell services knocked out by a hurricane in Puerto Rico, comes a year after the Android-maker ended Google Station, its other major connectivity effort to bring internet to the next billion users.' -- source: https://tech.slashdot.org/story/21/01/22/1418212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Talks With TSMC, Samsung To Outsource Some Chip Production
by Peter Reutemann 22 Jan '21

'Intel has talked with TSMC and Samsung about the Asian companies making some of its best chips, but the Silicon Valley pioneer is still holding out hope for last-minute improvements in its own production capabilities. Bloomberg reports: After successive delays in its chip fabrication processes, Santa Clara, California-based Intel has yet to make a final decision less than two weeks ahead of a scheduled announcement of its plans, according to people familiar with the deliberations. Any components that Intel might source from Taiwan wouldn't come to market until 2023 at the earliest and would be based on established manufacturing processes already in use by other TSMC customers, said the people, asking not to be identified because the plans are private. Talks with Samsung, whose foundry capabilities trail TSMC's, are at a more preliminary stage, the people said. An Intel spokesperson referred to previous comments by Bob Swan, the company's chief executive officer. Swan has promised investors he'll set out his plans for outsourcing and get Intel's production technology back on track when the company reports earnings Jan. 21. [...] TSMC, the largest maker of semiconductors for other companies, is preparing to offer Intel chips manufactured using a 4-nanometer process, with initial testing using an older 5-nanometer process, according to the people. The company has said it will make test production of 4-nanometer chips available in the fourth quarter of 2021 and volume shipments the following year. The Taiwanese company expects to have a new facility in Baoshan operational by the end of this year, which can be converted to production for Intel if required, one of the people said. TSMC executives previously said the new Baoshan unit would house a research center with 8,000 engineers. While Intel has outsourced production of lower-end chips before, it has kept the manufacturing of its best semiconductors in-house, considering it a competitive strength. Its engineers have historically tailored their designs to the company's manufacturing processes, making a shift to outsourcing of flagship products unthinkable in the past. As the provider of 80% of personal computer and server processors globally, Intel produces hundreds of millions of chips each year. That scale dictates that any potential supplier must create new capacity to accommodate Intel.' -- source: https://hardware.slashdot.org/story/21/01/08/2215226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

“When Elephants Fight, The Grass Gets Trampled”
by Lawrence D'Oliveiro 22 Jan '21

22 Jan '21

When big news organizations tussle with big Web search engines and social media outfits over who is stealing revenue from whom, how do you decide who is right and who is wrong? The Aussie Government is trying to protect one lot of multinational companies from the encroachments of another lot; where does fair competition end and protectionism or exploitation begin? <https://www.nzherald.co.nz/business/google-threatens-to-ban-search-button-i…> (By the way, in that old African proverb, the “grass” is the ordinary people who are the inevitable victims in any conflict between major powers.)

Ubuntu Now Runs On Apple Silicon, Devs Say It's 'Completely Usable'
by Peter Reutemann 22 Jan '21

22 Jan '21

'Developers at ARM virtualisation company Corellium have managed to get Ubuntu 20.04 up and running on the new Apple Silicon Mac Mini. And we're not talking 'it boots and prints a load of text' running here. No, this is the full Ubuntu desktop experience -- and it's already being described as "completely usable!" Pretty impressive, right? Even Linus Torvalds wasn't convinced that Linux M1 support was likely to appear anytime soon. He told ZDnet's Steven J. Vaughan-Nichols that: "...the main problem with the M1 for me is the GPU and other devices around it, because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up." Not that he was entirely wrong, mind. GPU support is indeed a current sticking point in Correllium's Linux for M1 effort. It doesn't (yet) include M1 GPU support meaning 'graphics' handling is done via software rendering.' -- source: https://news.slashdot.org/story/21/01/21/1329258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
