  • GNU Linux-libre Kernel 4.4 Officially Released for Those Who Want 100% Freedom

    The guys over at the GNU Linux-libre project have had the great pleasure of announcing the release and immediate availability for download of the GNU Linux-libre 4.4 kernel on January 10, 2016.

  • With Skylake Out, It's Becoming Easier To Build A Cheap Haswell Xeon Linux System

    Now that Skylake Xeon processors are appearing at major Internet retailers in sufficient quantities (such as the recently reviewed Intel Xeon E3 1245 v5), prices on older-generation Xeon CPUs are falling further. With prices on DDR3, SSDs, and Haswell-compatible motherboards also continuing to fall, it's possible to build a sufficiently powerful yet cheap Haswell Xeon system.

  • Cgroup v2 Is To Be Made Official With Linux 4.5

    The cgroup v2 interface will be made official with the in-development Linux 4.5 kernel.

    Maintainer Tejun Heo sent in the cgroup changes today for the Linux 4.5 merge window. About the new interface he notes, "cgroup v2 interface is now official. It's no longer hidden behind a devel flag and can be mounted using the new cgroup2 fs type. Unfortunately, cpu v2 interface hasn't made it yet due to the discussion around in-process hierarchical resource distribution and only memory and io controllers can be used on the v2 interface at the moment."

  • 4.4 Linux Kernel Long-Term Support Release is Now Available

    Linus Torvalds yesterday released the Linux 4.4 kernel. This is a long-term support (LTS) release, as was determined at the Linux Kernel Summit and announced in October by Greg Kroah-Hartman, who will maintain it for 2 years.

    This release checks in at more than 20.8 million lines of code, which is up considerably from Version 4.1, released in June 2015 with slightly more than 19.5 million lines of code, according to Phoronix. For historical comparison, version 0.01 of the Linux kernel -- released in 1991 -- had just 10,239 lines of code (source: Wikipedia).

  • LinuxChanges

    Summary: This release adds support for 3D support in virtual GPU driver, which allows 3D hardware-accelerated graphics in virtualization guests; loop device support for Direct I/O and Asynchronous I/O, which saves memory and increases performance; support for Open-channel SSDs, which are devices that share the responsibility of the Flash Translation Layer with the operating system; the TCP listener handling is completely lockless and allows for faster and more scalable TCP servers; journalled RAID5 in the MD layer which fixes the RAID write hole; eBPF programs can now be run by unprivileged users, they can be made persistent, and perf has added support for eBPF programs aswell; a new mlock2() syscall that allows users to request memory to be locked on page fault; and block polling support for improved performance in high-end storage devices. There are also new drivers and many other small improvements.

  • 4 tips for teaching kids how to build electronics
    Kids are naturally curious about how things work, and with a new trend in hardware companies creating open source hardware products, it's a great time to teach kids about electronics. But modern technology can seem too complex to even begin to understand. So where do you start?
  • Oil companies joining open source world by sharing data [Ed: No, oil companies, sharing data is open data and not open source. More openwashing, like greenwashing]
    The oil and gas industry has long collected huge volumes of data, but it hasn’t always known quite what to do with it all. Often, the terabytes aren’t even stored on computer systems that readily talk to each other. Industry insiders are used to it, said Michael Jones, senior director of strategy at the oil and gas software maker Landmark. But it’s not OK, he said. So, about a year ago, Jones and some of his oil industry colleagues set about to fix it. This week, at Landmark’s Innovation Forum & Expo at the Westin hotel in northwest Houston, the company unveiled the beginnings of a collaborative its members called groundbreaking. In a move to drive technology further, faster — and, perhaps, take a bigger piece of the burgeoning big-data market — Landmark is pushing its main computing platform into the cloud, for all to use.

Linux at 25: How Linux changed the world

I walked into an apartment in Boston on a sunny day in June 1995. It was small and bohemian, with the normal detritus a pair of young men would scatter here and there. On the kitchen table was a 15-inch CRT display married to a fat, coverless PC case sitting on its side, network cables streaking back to a hub in the living room. The screen displayed a mess of data, the contents of some logfile, and sitting at the bottom was a Bash root prompt decorated in red and blue, the cursor blinking lazily. I was no stranger to Unix, having spent plenty of time on commercial Unix systems like OSF/1, HP-UX, SunOS, and the newly christened Sun Solaris. But this was different. Read more

Linux Kernel News and Microsoft Breaks PowerShell

  • Coherent Accelerators, FPGAs, and PLD Microconference Accepted into 2016 Linux Plumbers Conference
    It has been more than a decade since CPU core clock frequencies stopped doubling every 18 months, which has shifted the search for performance from the "hardware free lunch" to concurrency and, more recently, hardware accelerators. Beyond accelerating computational offload, field-programmable gate arrays (FPGAs) and programmable logic devices (PLDs) have long been used in the embedded space to provide ways to offload I/O or to implement timing-sensitive algorithms as close as possible to the pin.

Android Leftovers

  • Xiaomi Redmi Note 4 unveiled in China, priced at $135
    Xiaomi took the wraps off their latest smartphone offering, the Redmi Note 4, earlier today, and as is expected from the budget-friendly Redmi series, the device offers a premium look, specifications, and features, and more importantly, an ultra-affordable price tag. The Redmi Note 4 retains the premium full metal unibody construction that was introduced with its predecessor, but now comes with a brushed metal finish and chamfered edges that looks and feels even better. The design language is quite similar as well, with the Redmi Note 4 also coming with a fingerprint scanner on the back. Under the hood, the Redmi Note 4 comes with a 5.5-inch Full HD display that is covered with a 2.5D curved glass panel. The phone is powered by a MediaTek Helio X20 processor, that is backed by the Mali-T880MP4 GPU and 2 GB or 3 GB of RAM. 16 GB or 64 GB are the on-board storage options available, which also dictates how much RAM you get, and you also get expandable storage via microSD card to cover all your needs. Keeping everything running is a huge 4,100 mAh battery.
  • New study finds iPhones fail far more often than Android phones
    Apple customers are generally a shockingly loyal bunch. The company’s high repeat customer rate can be attributed to a combination of factors that concern iPhones themselves as well as Apple’s industry-leading customer service. Dealing with Apple’s customer care department has always been a pleasure compared to dealing with rival companies, and iPhones themselves have historically been very reliable, offering a consistently smooth user experience that people love.

  • Two Nokia Android smartphones show up in benchmark
    Nokia is definitely coming out with a few Android smartphones later this year, but today's Nokia has little in common with the company that ruled the mobile phone industry for years. For starters, the devices that will be released this year, or the next, will be made by a third-party company. Nokia won't be manufacturing phones anymore and most likely it won't manage the way they are sold through retailers and authorized resellers.
