  • Linus Torvalds tears into Intel, favors AMD

    After 15 years of using Intel-based processors for his Linux-building powerhouse computers, Linus Torvalds switched to an AMD Threadripper 3970x-based  "frankenbox" for building the world's most important operating system, Linux. Now, months later, Torvalds is glad of the move and wrote that he's "very happy with AMD these days."

  • Colin King: Improving kernel test coverage with stress-ng

    Over the past year there has been focused work on improving the test coverage of the Linux Kernel with stress-ng.  Increased test coverage exercises more kernel code and hence improves the breadth of testing, allowing us to be more confident that more corner cases are being handled correctly.

    [...]

    Each stress-ng release is run with various stressor options against the latest kernel (built with gcov enabled).  The gcov data is processed with lcov to produce human readable kernel source code containing coverage annotations to help inform where to add more test coverage for the next release cycle of stress-ng.  

    Linux Foundation sponsored Piyush Goyal for 3 months to add test cases that exercise system call test failure paths and I appreciate this help in improving stress-ng. I finally completed this tedious task at the end of 2020 with the release of stress-ng 0.12.00.

    Below is a chart showing how the kernel coverage generated by stress-ng has been increasing since 2015. The amber line shows lines of code exercised and the green line shows kernel functions exercised.

  • Linux Foundation Gobbles Open19, Adds Cisco

    The Open19 Foundation — an open data center hardware initiative founded in 2016 by LinkedIn, Hewlett Packard Enterprise (HPE), and VaporIO — is now a Linux Foundation project. It officially made the move on Jan. 1, after Open19 added Cisco as a board member late last year.

  • Linux creator isn't happy with Intel, here's why

    “I'm personally very happy with AMD these days. I used to absolutely despise their horrible bulldozer cores, but I think they've had a home run with their Ryzen series and their chiplet approach. Not just because they fixed their cores, but because their chiplets made it so much easier to do the scaling they do and offer close to that "twice the cores for twice the price" model,” wrote Torvalds in a forum post by Real World Technologies.

  • Linus Torvalds, creator of Linux, calls out Intel on the importance of ECC RAM in the consumer market space

    According to Linus, Intel blocked the widespread use of error-correcting memory and “killed the entire ECC industry” with bad market segmentation. He responded in the Forums after another poster dismissed the importance of ECC memory.

    ECC is an abbreviation for error correction code. ECC memory uses additional parity bits to ensure that the data read from memory is the same as the data written. Without this check, memory is vulnerable to occasional corruption, where bits spontaneously flip, for example due to background radiation.

  • Linus Torvalds Rails At Intel For 'Killing' the ECC Industry

    Linux creator Linus Torvalds has accused Intel of preventing widespread use of error-correcting memory and being "instrumental in killing the whole ECC industry with its horribly bad market segmentation." ECC stands for error-correcting code. ECC memory uses additional parity bits to verify that the data read from memory is the same as the data that was written. Without this check, memory is vulnerable to occasional corruption where a bit is flipped spontaneously, for example, by background radiation. Memory can also be attacked using a technique called Rowhammer, where rapid repeated reads of the same memory locations can cause adjacent locations to change their state. ECC memory solves these problems and has been available for over 50 years yet most personal computers do not use it. Cost is a factor but what riles Torvalds is that Intel has made ECC support a feature of its Xeon range, aimed at servers and high-end workstations, and does not support it in other ranges such as the Core series.

  • New year, new rant: Linus Torvalds rails at Intel for 'killing' the ECC industry

    ECC memory solves these problems – well, ish, in the case of Rowhammer – and has been available for over 50 years yet most personal computers do not use it.

Linux's Linus Torvalds roasts Intel on lack of ECC memory (RAM)

  • Linux's Linus Torvalds roasts Intel on lack of ECC memory (RAM) support

    We’re in a new year, which means there’s equally a lot of new technology to look forward to at the upcoming CES 2021 digital event. Companies tend to shift the focus in new directions at these kinds of events, and Linux founder Linus Torvalds seems more than ready to get the discussion going about ECC memory. While it may still be a little soon for programming wizards to enjoy universally better standards, ECC memory is certainly still worth discussing due to its inclusion in the JEDEC spec for the upcoming DDR5 generation.

    So what is this thing you might ask? Well, in short, ECC memory is a specific kind of system RAM that differs from DRAM in a key way. It features an extra chip on each module which performs automatic error correction checks. If it detects an error in how the data was written, the extra chip is able to correct the error in most cases. It’s great for developers, but currently lacks broad support across the consumer space.

  • Kernel now 5.15.60 with RTLXXXU driver

    I have had email communications with Muthukrishnan, Realtek wifi not working, but it does work on a different Linux distribution. He has investigated firmware, but narrowed the problem down to a missing kernel driver. This is part of one of his emails: The issue appears to be that CONFIG_RTL8XXXU is not set in the kernel config setting. Since the firmware for my laptop is RTL8723BU, it appears to be not loading it at the time of booting.

  • Level up your HTML document with CSS | Opensource.com

    When you write documentation, whether that's for an open source project or a technical writing project, you should have two goals: The document should be written well, and the document should be easy to read. The first is addressed by clear writing skills and technical editing. The second can be addressed with a few simple changes to an HTML document. HyperText Markup Language, or HTML, is the backbone of the internet. Since the dawn of the "World Wide Web" in 1994, every web browser uses HTML to display documents and websites. And for almost as long, HTML has supported the stylesheet, a special addition to an HTML document that defines how the text should appear on the screen. You can write project documentation in plain HTML, and that gets the job done. However, plain HTML styling may feel a little spartan. Instead, try adding a few simple styles to an HTML document to add a little pizzazz to documentation, and make your documents clearer and easier to read.

  • Microsoft Sues Activation Key & Token Sellers For Enabling Customers' Piracy

    Software sold by market leaders tend to be primary purchases for regular consumers. Brand comfort is important but so too is affordability, especially when pirate copies are available for free. Some find a middle ground with purchases of discounted activation keys but, as a new Microsoft lawsuit shows, that can amount to copyright infringement for buyers and sellers alike.

  • No, you cannot trust third party code without reading it first

    For more than a decade I have been thundering against a lot of the bad practices that have permeated the software development industry, one such practice is to blindly trust code when using third party libraries, frameworks or packages. For about the same amount of time I have listened to all the reasons why time is money and we need to build something quickly, and we haven't got the time to do security or X, Y and Z. But alas, now such companies are beginning to pay the price, a very costly and extremely damaging price!

  • Database Integrity Vulnerabilities in Boeing’s Onboard Performance Tool | Pen Test Partners

    Security gaps in older, unprotected Windows desktop versions of Boeing’s Onboard Performance Tool (OPT) could make certain Electronic Flight Bags (EFB) more susceptible to attack. In particular, OPT’s use of plain text configuration files and SQLite databases, means an attacker with physical access to an EFB could modify files directly on the device. While the likelihood of exploiting such gaps is low given existing regulations governing the use and employment of EFBs and Crew Resource Management procedures, if data modification occurs, and the resulting miscalculations are not detected during the crew’s required cross check or verification process, an aircraft could land on a runway too short or take off at incorrect speeds potentially resulting in a tail strike or runway excursion. Boeing released OPT version 4.70 and issued a service bulletin to operators to enhance the application’s security features and minimize the potential for manipulating OPT data. It is important that operators employing EFB solutions, including those that contain OPT, harden their devices and implement physical access controls in accordance with relevant aviation regulations.

  • Sounding the Alarm on Emergency Alert System Flaws

    The Department of Homeland Security (DHS) is urging states and localities to beef up security around proprietary devices that connect to the Emergency Alert System — a national public warning system used to deliver important emergency information, such as severe weather and AMBER alerts. The DHS warning came in advance of a workshop to be held this weekend at the DEFCON security conference in Las Vegas, where a security researcher is slated to demonstrate multiple weaknesses in the nationwide alert system.

    However, sometimes companies struggle with understanding or feeling fully protected by those policies. According to a recent study from Blackberry and Corvus Insurance, a high percentage of companies said they would hesitate to get into business with organizations that aren't covered by cyber insurance, recognizing its importance. However, just 14 percent of small and medium-size businesses have policies that cover over $600,000, restrictions that led more than half of respondents to say they hoped for more financial assistance from the government, particularly when attacked by a nation state. Many companies said there's a lack of transparency from some firms about what is actually covered by their policies, which are constantly getting more expensive.

  • Researcher Finds Russian Cybersecurity Far Shittier Than The Mythology Suggests

    For much of the last decade, Vladimir Putin has attempted to compensate for various shortcomings (like a less sophisticated real world military) by launching cyber and propaganda attacks on much of the world. And while this, for a while, resulted in a mythology that Russia was in a league of its own when it comes to hacking and cybersecurity, the reality isn’t nearly that exciting.

10 Great Linux websites for beginners and everyday users

Many websites related to Linux and open source software have high technical content and often have less attention for the actual use and the things you can do with this operating system. But some of us just have other expectations. As a beginner or every day user in the Linux and Open Source world, you have different information needs than an experienced, highly skilled Linux user or developer. But also Linux users who use their computer for example for content creation, are less interested in the technical backgrounds, and have mostly different needs. In this artcle I give my thoughts on 10 great Linux websites for beginners and everyday users. Read on
