Over the past few days I've been messing with my home server and trying different Linux distros. I've gone from: Ubuntu > Xubuntu > Arch (trying to set it up but realizing I'm not ready for it yet) > Xubuntu > Manjaro So far, Manjaro XFCE has been to my liking. Fewer issues and things have been much easier to set up on that old machine. Just a shame the hardware is so old. P4 3.4GHz, 3GB RAM, and recently had to downgrade the PSU and graphics card (128MB card because the one before - a 512MB - had the fan go bad and make a lot of noise despite trying to fix it) in order to have a working, silent server PC once more.

Researchers at the University of California, Riverside have identified a weakness in the Transmission Control Protocol (TCP) of all Linux operating systems since late 2012 that enables attackers to hijack users’ internet communications completely remotely. Such a weakness could be used to launch targeted attacks that track users’ online activity, forcibly terminate a communication, hijack a conversation between hosts or degrade the privacy guarantee by anonymity networks such as Tor. Led by Yue Cao, a computer science graduate student in UCR’s Bourns College of Engineering, the research will be presented on Wednesday (Aug. 10) at the USENIX Security Symposium in Austin, Texas. The project advisor is Zhiyun Qian, an assistant professor of computer science at UCR whose research focuses on identifying security vulnerabilities to help software companies improve their systems. While most users don’t interact directly with the Linux operating system, the software runs behind-the -scenes on internet servers, android phones and a range of other devices. To transfer information from one source to another, Linux and other operating systems use the Transmission Control Protocol (TCP) to package and send data, and the Internet Protocol (IP) to ensure the information gets to the correct destination.

linux Linux distributions will soon stop supporting 32-bit PCs
NewsBot posted a topic in Backpage News
AMD and Intel released the first 64-bit CPUs for consumers back in 2003 and 2004. Now, more than a decade later, Linux distributions are looking at winding down support for 32-bit hardware. Google already took this leap back in 2015, dumping 32-bit versions of Chrome for Linux. Ubuntu’s Dimitri John Ledkov put forth a proposal to wind down 32-bit support on the Ubuntu mailing list recently. Hardware that can’t run 64-bit software is becoming much less common, while creating 32-bit images, testing them, and supporting them takes time and effort. (On Linux, the “i386” architecture is the standard 32-bit for Intel-compatible CPUs, while “amd64” is the 64-bit architecture originally made by AMD that Intel CPUs are compatible with.)

After six years of litigation, Sony is now agreeing to pay the price for its 2010 firmware update that removed support for the Linux operating system in the PlayStation 3. Sony and lawyers representing as many as 10 million console owners reached the deal on Friday. Under the terms of the accord, (PDF) which has not been approved by a California federal judge yet, gamers are eligible to receive $55 if they used Linux on the console. The proposed settlement, which will be vetted by a judge next month, also provides $9 to each console owner that bought a PS3 based on Sony's claims about "Other OS" functionality. The deal also provides up to $2.25 million in attorneys' fees for the lawyers who brought suit. Under the plan, gamers eligible for a cash payment are "all persons in the United States who purchased a Fat PS3 model in the United States between November 1, 2006, and April 1, 2010." The accord did not say how much it would cost Sony, but the entertainment company is expected to pay out millions. The troubles began with the PS3 software update 3.21. On March 28, 2010, Sony announced that the update would "disable the 'Install Other OS' feature that was available on the PS3 systems prior to the current slimmer models." This feature, Sony claimed, would be removed "due to security concerns." View the full article

Ubuntu's "snappy" new way of packaging applications is no longer exclusive to Ubuntu. Canonical today is announcing that snapd, the tool that allows snap packages to be installed on Ubuntu, has been ported to other Linux distributions including Debian, Arch, Fedora, and Gentoo, among others. If you have no idea what the above paragraph means, here's a summary. Traditionally, applications for Ubuntu and similar distributions are packaged in the deb (short for Debian) format. These packages consist of the application a user wants to install, and they can also install other things that the package depends on in order to run (libraries, other applications, scripting, support files, and so on). Applications often require a lot of dependencies, making things more complicated, for example, when one application needs one version of another piece of software and a second application needs a different version of that other piece of software. "Snap packages solve this problem by creating self-contained packages," we noted in our review of Ubuntu 16.04, which brought snaps to servers and desktops. "With snap packages, applications are installed in their own container, and all the third-party applications are installed with them so there are no version conflicts. Snap packages are also smart enough to not install a package more than once, meaning applications installed via Snappy don't take any more disk space than regular applications." This allows users to update and roll back applications without causing problems to the rest of their operating system. It also comes with security benefits because applications are more isolated from each other and from core parts of the OS than they normally would be. View the full article

Put down your coffee gently. Microsoft has today released a homegrown open-source operating system, based on Debian GNU/Linux, that runs on network switches. The software is dubbed SONiC, aka Software for Open Networking in the Cloud. It's a toolkit of code to bend switch hardware to your will, so you can dictate how it works and what it can do, rather than relying on proprietary firmware from a traditional networking vendor. It also pits Redmond against white-box network operating systems from the likes of HP, Dell, and Cumulus Networks. SONiC builds upon the Windows giant's Linux-based Azure Cloud Switch (ACS) operating system that we learned about in September. ACS is the brains of switches in Microsoft's Azure cloud: the code can run on all sorts of hardware from different equipment makers, and uses a common C API – the Switch Abstraction Interface (SAI) – to program the specialist chips in the networking gear. This means ACS can control and manage network devices and implement features as required regardless of who made the underlying electronics. View the full article

skype Microsoft rewards Linux users with new version of Skype
NewsBot posted a topic in Backpage News
Linux users are not the most sociable bunch. Sure, I am generalizing, but I speak from experience. Not only do I know many socially awkward and inept Linux nerds, but I am one myself. While I do not use operating systems based on the kernel exclusively, I use them often, and understand preferring the company of a computer to other humans. Still, every once in a while, a Linux nerd must communicate with family or friends and what better way to do that than video chat? Skype is one of the best options, although some Linux users refuse to use it since Microsoft acquired it. Me? I could care less who owns it as long as it functions as I expect. Today, Microsoft reaffirms its commitment to Linux with a new version of Skype. Microsoft touts the following changes: An updated UI Our new cloud-based Group Chat experience More reliable file transfer support when using multiple devices at once Greater accessibility by blind and visually impaired users PulseAudio 3.0 and 4.0 support Lots of bug fixes Sadly for some users, ALSA support has been dropped, so you must use PulseAudio. However, most users should not have a problem with this. Source: BetaNews View the full article -
While self-learning and real-world experience are both great types of education, there is still something to be said for a quality, structured classroom lesson. College is a great place for structured learning, but the costs can be overwhelming. Even though education and self improvement are great investments, no one wants to be buried in student loan debt. If you are interested in learning, the subject of Linux is a great choice. After all, more and more businesses are utilizing Linux-based operating systems, while Android and Chrome OS are increasing in popularity. Luckily, the Linux Foundation has partnered with edX to bring free Linux courses to the masses. "The Linux Foundation and edX are partnering to develop a MOOC program that will help address this issue by making basic Linux training materials available to all for free. Previously a $2,400 course, Introduction to Linux will be the first class available as a MOOC and will be free to anyone, anywhere. The Linux Foundation is among a new group of member organizations edX announced today who will contribute courses to the platform.", says the foundation. View the full article
