Three great Android tools for Linux and Windows sysadmin

Filed under

Linux

Systems administration isn't a simple job — and being able to respond to issues quickly is a definite plus. Not long ago, server problems meant receiving a phone alert followed by a trip to the data center to fix whatever was wrong. Today, having full-powered computers such as smartphones or tablets literally in your hand is a tremendous help when doing sysadmin. Load Android with a few key applications and you can remotely monitor servers and services, get alerts and warnings as they occur, and solve problems without any travel at all.

Parallels CTO: Linux container security is not the problem

Security

Containerization technology has been a game-changer, powering Docker and other transformative software solutions. It's also garnered its share of criticisms about performance, security, and resiliency.

But one of the creators of Parallels, a key containerization technology on Linux, is pushing back against what he feels are pervasive myths about containers -- many of which, he argues, are rooted in misunderstandings of how to use them and what they're for.

Good dog: Puppy Linux reaches version 6.0

Linux is pretty darn awesome when used on super-powerful machines. However, where the kernel really shines is when operating systems leverage it for less powerful computers. In other words, Linux can breathe new life into old computers thanks to lightweight distributions.

Lightweight DBMS guides Linux-based cow feeding robot

Linux
Sci/Tech

Ittia announced a design win for its lightweight embedded DB SQL database in Wasserbauer’s uClibc Linux based “Butler Gold” robot designed to feed cattle.

The Ittia DB SQL database and its antecedents, including .db*, have shipped in a wide variety of devices, including a circa 2005, Linux-based Oshkosh A3 HEMTT tactical truck. The lightweight, Linux- and Android-compatible embedded relational database has now found its way into barnyard life in its role within a Butler Gold cattle-feeding robot from Germany’s Wasserbauer GmbH. Linux has previously played a role in DeLaval’s Voluntary Milking System robot for cattle, but this is the first time we’ve seen it helping out on the other end.

Desktop GNU/Linux Wins

Filed under
GNU
Linux

To me, this is quite an important period because the only reason I migrated to GNU/Linux was to be free of crashes. Later I was glad I did because of performance, lack of malware, avoidance of the EULA from Hell, easy back-ups and installation, easy management, etc. Many other famous migrations happened around the same time and I would bet stability was an issue for them too. Certainly cost, flexibility, and independence from M$ were issues. Many businesses were spending ~$1000 per seat per annum just to keep things running, so it’s not just about licences or being “cheap”. FLOSS is the right way to do IT.

15 books for kids who (you want to) love Linux and open source

In my job I've heard professionals in tech, from C-level executives to everyone in between, say they want their own kids to learn more about Linux and open source. Some of them seem to have an easy time with their kids following closely in their footsteps. And some have a tough time getting their kids to see what makes Linux and open source so cool. Maybe their time will come, maybe it won't. There's a lot of interesting, valuable stuff out there in this big world. Read more

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.
