Jolla has opened pre-orders on Jolla Tablets starting at $300. The 7.9-inch 2048 x 1536 tablet runs the Linux-based Sailfish OS 2.0 on a quad-core Atom.

The Jolla Tablet has been a long time coming for Indiegogo backers, but the participants will finally receive their tablets in September, says Finland-based Jolla. Now anyone can order the tablets, with shipments due to start in late October. Quantities are said to be limited.

Former Google engineer revs up a new Linux filesystem

Filed under

Google

An ex-Google engineer is developing a new file system for Linux, with the hopes that it can offer a speedier and more advanced way of storing data on servers.

After a number of years of development, the Bcache File System (Bcachefs) "is more or less feature complete -- nothing critical should be missing," wrote project head Kent Overstreet, in an e-mail to the Linux Kernel Mailing List late Thursday.

Embedded controller adds CAN and serial hooks to Pi 2

Linux

The emPC-A/RPI follows in a long line of emPC-branded industrial computers dating back to the Xenomai Linux supported emPC-M from 2008 when Germany-based Janztec went by the name Janz Automationssysteme AG. Janztec continues to sell products in the U.S. via Saelig, which is shipping the emPC-A/RPI for $309. The price goes to $364 if you add a microSD card loaded with Raspbian Linux for the computer’s quad-core, 900MHz Raspberry Pi 2 Model B mainboard.

Live Booting Linux

Filed under
Linux

“I’d like to give Linux a try, but I’m not sure how.”

I’ve heard that statement so many times over the years. During that period, my pat response has changed from something akin to “It’s worth the effort” to “It’s incredibly easy.” Linux is, actually, the single most easy operating system to “try out.” How is that possible? Two words… live booting.

A User’s Eye View of Bodhi 3.1.0 & Moksha

Filed under
Linux

The Bodhi development folks have been busy bees since lead developer Jeff Hoogland returned to retake his place beneath the Bodhi tree. First, there was the release of version 3.0.0 back in February. Then, a couple of weeks ago came the release of 3.1.0. Although this might be supposed to be a “minor” point grade release, it’s a “big deal” according to the distro’s website. Why? Because it introduces a new desktop called Moksha.

The dummy’s guide to a first-time Linux install (it’s easier than you think)

Filed under
GNU
Linux

If you’ve never installed Linux before and are just about dipping into the realm of free and open source software, go ahead and first read this primer to get acquainted. This done, it’s time to roll up those sleeves and jump right in: we’ll show you here how to install Linux on either a hard disk or straight to a USB drive where you needn’t disturb your current configuration--Linux is flexible that way.

For the purpose of this hands on, I’ve selected Linux Mint as our distribution of choice. Linux Mint is based on two other popular Linux distributions--Debian and Ubuntu--both of which are mature operating systems in their own right, and well-known for an extensive feature set and solid stability.

Now your Raspberry Pi can water your lawn

Hardware

Lawn watering systems are notorious for sending money down the drain. When Robert Booth was looking to get started on a robotics project, it's no surprise that a sprinkler system was at the top of his list. Booth will be presenting his "Strawberry Pi" system at Texas Linux Fest this year. We talked to him about it.

Linux 4.3 Kernel To Add The MOST Driver Subsystem

Filed under
Linux

While the Linux 4.2 kernel hasn't been officially released yet, Greg Kroah-Hartman sent in early his pull requests for the various subsystems he maintains for the Linux 4.3 merge window.

The pull requests sent in by Greg KH on Thursday include the Linux 4.3 merge window updates for the driver core, TTY/serial, USB driver, char/misc, and the staging area. These pull requests don't offer any really shocking changes but mostly routine work on improvements / additions / bug-fixes. The staging area once again is heavy with various fixes and clean-ups but there's also a new driver subsystem.

Nothing Could Be Finer Than Point Linux

Linux

Point Linux is an ideal choice for users who do not want to spend a lot of time fussing with configurations and playing around with eye candy and desktop doodads. I have used it to introduce newcomers to computing in general, and to introduce avid Windows users to the Linux OS. Point Linux produced smiles and frustration-free experiences for them -- and me.

Security: VPNFilter, Encryption in GNU/Linux, Intel CPU Bug Affecting rr Watchpoints

  • [Crackers] infect 500,000 consumer routers all over the world with malware

    VPNFilter—as the modular, multi-stage malware has been dubbed—works on consumer-grade routers made by Linksys, MikroTik, Netgear, TP-Link, and on network-attached storage devices from QNAP, Cisco researchers said in an advisory. It’s one of the few pieces of Internet-of-things malware that can survive a reboot. Infections in at least 54 countries have been slowly building since at least 2016, and Cisco researchers have been monitoring them for several months. The attacks drastically ramped up during the past three weeks, including two major assaults on devices located in Ukraine. The spike, combined with the advanced capabilities of the malware, prompted Cisco to release Wednesday’s report before the research is completed.

  • Do Not Use sha256crypt / sha512crypt - They're Dangerous

    I'd like to demonstrate why I think using sha256crypt or sha512crypt on current GNU/Linux operating systems is dangerous, and why I think the developers of GLIBC should move to scrypt or Argon2, or at least bcrypt or PBKDF2.

  • Intel CPU Bug Affecting rr Watchpoints
    I investigated an rr bug report and discovered an annoying Intel CPU bug that affects rr replay using data watchpoints. It doesn't seem to be hit very often in practice, which is good because I don't know any way to work around it. It turns out that the bug is probably covered by an existing Intel erratum for Skylake and Kaby Lake (and probably later generations, but I'm not sure), which I even blogged about previously! However, the erratum does not mention watchpoints and the bug I've found definitely depends on data watchpoints being set. I was able to write a stand-alone testcase to characterize the bug. The issue seems to be that if a rep stos (and probably rep movs) instruction writes between 1 and 64 bytes (inclusive), and you have a read or write watchpoint in the range [64, 128) bytes from the start of the writes (i.e., not triggered by the instruction), then one spurious retired conditional branch is (usually) counted. The alignment of the writes does not matter, and it's not related to speculative execution.

In Memoriam: Robin "Roblimo" Miller, a Videographer and Free Software Champion

Videographer Robin Roblimo Miller

Robin "Roblimo" Miller was a clever, friendly, and very amicable individual who everyone I know has plenty of positive things to say about. I had the pleasure of speaking to him for several hours about anything from personal life and professional views. Miller was a very knowledgeable person whose trade as a journalist and video producer I often envied. I have seen him facing his critics in his capacity as a journalist over a decade ago when he arranged a debate about OOXML (on live radio). Miller, to me, will always be remembered as a strong-minded and investigative journalist who "did the right thing" as the cliché goes, irrespective of financial gain -- something which can sometimes be detrimental to one's longterm health. Miller sacrificed many of his later years to a cause worth fighting for. This is what we ought to remember him for. Miller was - and always will be - a FOSS hero.

May everything you fought for be fulfilled, Mr. Miller. I already miss you.
