TuxMachines: today's leftovers

Wednesday 21st of December 2016 11:36:00 PM
  • [GNOME Maps] Nearing end of year

    So we're approaching the end of 2016, and I thought I should probably give a little update as it was a while since last time now…

    As can be seen in the screenshot below, the route labels will be expanded a to fill out the available space instead of getting ellipsized when there is no headsign label, as is the case for the Staten Island Ferry in the example

  • 5 rock-solid Linux distros for developers

    Developers love things their way and no other way. To that end, Linux stands to be the ultimate developer’s desktop environment. Linux is endlessly customizable, and it provides easy access to nearly all the software a developer might need. But a good Linux for developers must have other key attributes—like a comfortable work environment, good documentation, and useful features that a developer can benefit from generally.

  • Free FPGA programming with Debian

    FPGA (Field Programmable Gate Array) are increasingly popular for data acquisition, device control and application acceleration. Debian now features a completely Free set of tools to program FPGA in Verilog, prepare the binary and have it executed on an affordable device.

  • What we did at the Debian Edu / Skolelinux gathering in November 2016 in Oslo

    From November 25 to 27 some people met in the hackerspace bitraf in downtown Oslo. On Saturday and Sunday we met in the morning and hacked and translated all day until we went for dinners in the evening. Despite the short time I think we managed to get a lot done and had good fun, so I'm hoping we'll have another gathering in 2017!

  • Permabit Technology Corporation's Albireo VDO for Ubuntu Server

    In perfect alignment with its self-described identity as "the data reduction expert", Permabit Technology Corporation recently announced availability of its Albireo Virtual Data Optimizer (VDO) 6 for Canonical's Ubuntu Server. VDO data reduction enables enterprise hybrid cloud data centers and cloud service providers to reduce their storage footprint, increase data density and avoid costly data-center expansions, resulting in "massive savings on data-center investment".

  • Evaluating Microsoft Versus Linux for IoT

    It is an operating system based on open source software. The underlying source code can be used, distributed or modified (commercially or non-commercially) by anyone under terms of respective licenses. Linux runs on mobile phones, tablets, network routers, TiVo, smartwatches, video game consoles and television sets.

    Android is a derivative of the GNU/Linux operating system, which is an open source, unix-like operating system. Other popular open source products developed over the years and are still extensively used are Chromium, Mozilla Firefox, LibreOffice, Apache HTTP Server, etc.

  • Guide to the Open Cloud: The State of Virtualization

    Is virtualization still as strategically important as it was now that we are in the age of containers? According to a Red Hat survey of 900 enterprise IT administrators, systems architects, and IT managers across geographic regions and industries, the answer is a resounding yes. Virtualization adoption remains on the rise, and is integrated with many cloud deployments and platforms.

TuxMachines: Kernel Logs and Kernel Bisecter

Wednesday 21st of December 2016 11:35:08 PM
  • Chatty kernel logs

    Most people don't care about the kernel until it breaks or they think it is broken. When this happens, usually the first place people look is the kernel logs by using dmesg or journalctl -k. This dumps the output of the in- kernel ringbuffer. The messages from the kernel ring buffer mostly come from the kernel itself calling printk. The ring buffer can't hold an infinite amount of data, and even if it could more information isn't necessarily better. In general, the kernel community tries to limit kernel prints to error messages or limited probe information. Under normal operation the kernel should be neither seen nor heard. The kernel doesn't always match those guidelines though and not every kernel message is an urgent problem to be fixed.

    The kernel starts dumping information almost immediately after the bootloader passes it control. Very early information is designed to give an idea what kind of kernel is running and what kind of system it is running on. This may include dumping out CPU features and what areas of RAM were found by the kernel. As the kernel continues booting and initializing, the printed messages get more selective. Drivers may print out only hardware information or nothing at all. The latter is preferred in most cases.

  • Life of Kernel Bisecter

    Bisecting is extremely useful to fix a regression in big projects like upstream kernel. The goal here is to get the regression fixed instead of just reporting it and forget about it. Usually upstream regression reports have easily been ignored due to the bandwidth of the kernel developers, complex of the code analysis involved to find out the root cause, developers limited access to the hardware etc. However, since it is a regression, it is usually possible to track down which exact commit introduced it. Hence, make it is way easier for developers to figure out the root cause and come up with a fix. Also, the original authors who introduced the regression usually response quickly (within one working day) because they want to maintain good reputations within the community. By introducing regression with their patches without fixing them quickly makes lives harder for them to get their future patches accepted by Linus and sub-system maintainers. Linus and friends are usually not afraid of and good at making them feel public peer pressure once happened. In the worst case, the solution is to send a revert patch to fix the regression. Usually, it will be accepted as Linus and friends because they absolutely hate regressions even the trivial ones.

TuxMachines: Leftovers: OSS

Wednesday 21st of December 2016 11:30:23 PM
  • Google Open Up a Cool Collection of Cryptographic Security Tests

    With 2016 closing out, there is no doubt that cloud computing and Big Data analytics would probably come to mind if you had to consider the hot technology categories of the year. However, steady progress has been made in security software as well, and now Google has released Project Wycheproof, a collection of security tests that check cryptographic software libraries for known weaknesses that are used in attacks.

    This newly open sourced project, named for Mount Wycheproof, apparently the smallest mountain in the world, features a code repository on GitHub.

  • Kickstarter Open Sources its Own iOS and Android Apps

    If you're familiar with Kickstarter, you know that it and other crowdsourced funding sites have helped fund numerous open source applications. Kickstarter actually has its own engineering team, though, and now that team has made the announcement that it is open sourcing its own Android and iOS creations.

    You can go to the team's Android or iOS Github pages and find repositories. "The native team at Kickstarter is responsible for building and maintaining features for Android and iOS," the team reports. The open source toolsets may be especially useful for startups to leverage.

  • 2016 Hacktoberfest ignites open source participation

    DigitalOcean launched Hacktoberfest in 2014 to encourage contribution to open source projects. The event was a clear success, and in terms of attendance and participation goals reached, it's also clear that Hacktoberfest has become a powerful force in driving contributions to open source. The lure of a t-shirt and specific, time-limited goals help new contributors get started and encourage existing contributors to rededicate themselves and their efforts.

  • Oracle is cracking down on Java SE users who think it's free

    ORACLE HAS begun an aggressive campaign of chasing licence fees for use of payable elements of its Java software.

    The company, which acquired Java owner Sun Microsystems in 2010, has already lost a case over the fair use of Java APIs in Google's Android operating system, but as it awaits another appeal hearing, it's going after a myriad of other companies that are using elements of the open source software that aren't actually free.

    Oracle has been hiring a legal team this year to bolster its License Management Services, which in turn has forced companies to hire compliance specialists, as it looks like Oracle has made 2017 the year of kicking ass.

Reddit: Video capture on Linux

Wednesday 21st of December 2016 10:35:02 PM

My google-foo has failed me. I've discovered lots of software to capture the screen, but not to use as a stand alone recording box.

What i want to do is capture an audio feed and 2 to 4 video feeds (HDMI, composite video, @1024). I'm cool if that requires a separate capture card for each individual video feed. It can just write the raw video to disk, and I'd combine them later after the recording is done.

Does anyone know of any suitable hardware and software that would get such a thing working on Linux?

LXer: How to find Android apps that respect user privacy

Wednesday 21st of December 2016 10:31:25 PM
Have you ever downloaded an Android app only to find that it wants access to all your phone's features and all of your data? This experience, while not ubiquitous, is frustratingly common. Even applications in the F-Droid repository are not immune to requesting permission to access things they should not even need to access. For example, there is a Minesweeper application in F-Droid that wants to be able to record audio and more

Security News

  • Wednesday's security updates
  • Secure your Elasticsearch cluster and avoid ransomware
    Last week, news came out that unprotected MongoDB databases are being actively compromised: content copied and replaced by a message asking for a ransom to get it back. As The Register reports: Elasticsearch is next. Protecting access to Elasticsearch by a firewall is not always possible. But even in environments where it is possible, many admins are not protecting their databases. Even if you cannot use a firewall, you can secure connection to Elasticsearch by using encryption. Elasticsearch by itself does not provide any authentication or encryption possibilities. Still, there are many third-party solutions available, each with its own drawbacks and advantages.
  • Resolve to Follow These 8 Steps for Better Data Security in 2017
    Getting physically fit is a typical New Year's resolution. Given that most of us spend more time online than in a gym, the start of the new year also might be a great time to improve your security “fitness.” As with physical fitness challenges, the biggest issue with digital security is always stagnation. That is, if you don't move and don't change, atrophy sets in. In physical fitness, atrophy is a function of muscles not being exercised. In digital fitness, security risks increase when you fail to change passwords, update network systems and adopt improved security technology. Before long, your IT systems literally become a “sitting duck.” Given the volume of data breaches that occurred in 2016, it is highly likely that everyone reading this has had at least one breach of their accounts compromised in some way, such as their Yahoo data account. Hackers somewhere may have one of the passwords you’ve used at one point to access a particular site or service. If you're still using that same password somewhere, in a way that can connect that account to you, that's a non-trivial risk. Changing passwords is the first of eight security resolutions that can help to improve your online security fitness in 2017. Click through this eWEEK slide show to discover the rest.
