Gitlab Backups ... What Backups?
by Lawrence D'Oliveiro 02 Feb '17

02 Feb '17

A harried sysadmin accidentally deletes nearly 300GB of data during a troublesome data replication process ... and then they discover that, out of 5 different recovery procedures they thought they had available, none work. <http://www.theregister.co.uk/2017/02/01/gitlab_data_loss/>

LibreOffice 5.3 Released, Touted As 'One of the Most Feature-Rich Releases' Ever
by Peter Reutemann 02 Feb '17

02 Feb '17

'A new month, and a brand new version of open-source office suite LibreOffice is now available to download. And what a release it is. LibreOffice 5.3 introduces a number of key new features and continues work on improving the look and feel of the app across all major platforms. The Document Foundation describes LibreOffice 5.3 as "one of the most feature-rich releases in the history of the application." One of the headline features is called MUFFIN interface, a new toolbar design similar to the Microsoft Office Ribbon UI.' -- source: https://news.slashdot.org/story/17/02/01/1326204 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/

System76 GPGPU Server
by Lawrence D'Oliveiro 01 Feb '17

01 Feb '17

System76 announces its new Ibex Pro box <http://www.phoronix.com/scan.php?page=news_item&px=System76-Ibex-Pro-GPU-Se…> which can hold up to nearly 40,000 NVidia CUDA cores <https://system76.com/servers/ibex>. Not sure how many you get for that USD9,575 base price... Seems like there is no really competitive market for GPGPU hardware--it is totally dominated by NVidia, and nobody else gets a serious look-in. So the industry-standard OpenCL API languishes, since the dominant player prefers its own proprietary alternative, and there is little pressure from users to be able to port their code to competing products.

Google AI on raspberry pi
by rowan schischka 31 Jan '17

"Google has developed a huge range of tools for machine learning, IoT, wearables, robotics, and home automation, and it wants Raspberry Pi fans to fill out a survey <https://google.qualtrics.com/jfe/form/SV_3yMNYryaP4WsCwJ?Source=RaspPi> that will help it to understand what tools to provide." http://www.zdnet.com/article/google-is-bringing-ai-to-your-raspberry-pi/ I just took the survey and I don't get any impression of what tools they will bring to the r-pi. It was pretty simple, no email address required to participate. The questions were how old are you, what area are your projects in, and how frequently do you work on your projects. Im sure with the processing power of r-pi we'll see some sort of web API which wouldn't really need to be specific to the r-pi. It will be interesting to watch what they come up with so if you have maker projects, take the survey. -- Rowan Schischka

Backblaze 2016 Hard Drive Report
by Lawrence D'Oliveiro 31 Jan '17

31 Jan '17

<https://arstechnica.com/information-technology/2017/01/8tb-hgst-disks-show-…>: Traditionally, the company has stuck with consumer-oriented disks. Backblaze argues that the extra cost of "enterprise" disks doesn't make sense for its usage pattern. Other studies have shown no significant difference in reliability between “enterprise” and “consumer” disks anyway.

USB-C Power Meter
by Lawrence D'Oliveiro 31 Jan '17

31 Jan '17

With all the worries over bad USB-C cables and vendors that play fast and loose with the power spec, here <https://arstechnica.co.uk/gadgets/2017/01/usb-c-power-meter/> is a measurement gadget that can help to some extent. But as the article says: If you really want to test a new charger or cable before plugging it into an expensive device, your best bet is some DIYish electronics involving a breakout board and a multimeter. But there doesn't seem to be a plug-and-play version of that yet.

The Trump-And-Dump Bot
by Lawrence D'Oliveiro 30 Jan '17

30 Jan '17

This bot <http://www.theregister.co.uk/2017/01/30/trumps_corporate_twitter_trolling_t…> analyzes Trump’s tweets, identifies the company he is badmouthing, and does a quick short-sell to profit from the momentary dip in the company’s stock value. T3's approach involves using a Python Twitter bot and API calls to services like Indico for machine learning (sentiment analysis and entity recognition), Clearbit for company identification, Google Finance for stock pricing, and E‑Trade for executing the trade. They have been donating the profits to charity. Imagine that--an ethical use for short-selling...

Windows Users: It Might Be Time To Stop Using Antivirus
by Lawrence D'Oliveiro 27 Jan '17

27 Jan '17

The nail in the coffin, according to O'Callahan, is that software vendors rarely speak out about antivirus issues "because they need cooperation from the AV vendors." He then links to a mailing list thread in 2012, where he suggests keeping a list of the AV software that interferes with Firefox. Later in the thread, Mozilla PR swoops in and tells him to knock it off. <https://arstechnica.com/information-technology/2017/01/antivirus-is-bad/>

Code-Signing Vs Software Developers
by Lawrence D'Oliveiro 26 Jan '17

26 Jan '17

This item <http://www.theregister.co.uk/2017/01/26/windows_code_signing_changes/> is about Microsoft adopting some recommendations from the “Certificate Authority Security Council” that code-signing keys should be embedded in special hardware devices, not simply kept as files on a regular computer. Apparently they are also suggesting some yet-to-be-defined “cloud-based service” as an alternative, which raises some questions. One of the commenters linked this article <http://www.pcworld.com/article/2846653/storage-for-spies-how-the-fips-stand…> which gives a good overview of hardware signing key devices that are certified to the various levels of the FIPS 140-2 standard. The idea is not a new one. But like most security techniques that are worth a darn, it can cause all kinds of irritations in practical use.
