  • 'Kernel memory leaking' Intel processor design flaw forces Linux, Windows redesign

    A fundamental design flaw in Intel's processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level security bug.

    Programmers are scrambling to overhaul the open-source Linux kernel's virtual memory system. Meanwhile, Microsoft is expected to publicly introduce the necessary changes to its Windows operating system in an upcoming Patch Tuesday: these changes were seeded to beta testers running fast-ring Windows Insider builds in November and December.

    Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down, depending on the task and the processor model. More recent Intel chips have features – specifically, PCID – to reduce the performance hit.

  • A Huge Intel Security Hole Could Slow Down Your PC Soon

    Intel chips have a massive design flaw, and both Microsoft and the Linux kernel developers are scrambling to fix it. The security hole can be patched, but the patches will make PCs (and Macs) with Intel chips slower.

    We don’t know how much slowdown you’ll see yet, but one developer says a 5% slowdown will be fairly typical—at least on Linux—while certain tasks could experience slowdowns as high as 30%.

  • MacOS Kernel Flaw Could Allow Full-System Compromise

    A researcher going by the name “Siguza” unveiled a 15-year-old security vulnerability in Apple’s macOS operating system that could allow an attacker to fully compromise the system. The researcher also published proof-of-concept zero-day code to his GitHub page.

My Linux story: Coding not required

For more than 15 years, I have earned a living working exclusively with open source products. How did I get here? In many ways, my journey started before Linux existed. In college, I had friends who were admins in the engineering computer lab. Although I did not do too well in my CS programming classes, as a hobby and to spend time with my friends I learned about newgroups, ftp sites, and Unix systems. As a data aide student intern, I realized I made a good translator between the astronomers and the C programmer computer support staff. I could read just enough code to identify the problem, but not enough to actually fix it. Read more

Amazing Facts about Linux Operating System You Probably Don't Know

It was almost 30 years ago when the first version of Linux came into the market and since then, this operating system has made its important stature beside Microsoft Windows. Linux has turned out to be one of the most acknowledged and extensively used operating system. Enthused by UNIX, Linux has smartly managed to attract a lot of tech giants such as Facebook, Google, Yahoo, Twitter, Amazon, and much more. However, when it comes to assessing the exact rate of adoption of Linux in the market, the task is a bit tough since the sources to get copies are wide in number. Appreciating workers' and developers' hard-work, Linux has been designed in such a way that exploring and learning things on this operating system has become quite captivating and enthralling. In this post, let's know more about amazing features and facts of this operating system. Read more
