    On Tuesday, Google released the first iteration of Chrome OS 73 for the Dev Channel and there are quite a few new items related to Project Crostini, for Linux app support. Some things in the lengthy changelog only set up new features coming soon while others add new functionality. Here’s a rundown on some of the Crostini additions to Chrome OS 73.

  • Tens to be disappointed as Windows 10 Mobile death date set: Doomed phone OS won't see 2020

    Microsoft has formally set the end date for support of its all-but-forgotten Windows 10 Mobile platform.

    The Redmond code factory said today that, come December 10, it's curtains for the ill-fated smartphone venture. The retirement will end a four-year run for a Microsoft phone effort that never really got off the ground and helped destroy Nokia in the process.

    "The end of support date applies to all Windows 10 Mobile products, including Windows 10 Mobile and Windows 10 Mobile Enterprise," Microsoft declared.

Linux 5.0-rc3 Kernel Released With Plenty Of Fixes Plus Nouveau RTX 2080 Ti Support

Filed under
Linux

Linus Torvalds has released the third weekly release candidate for the upcoming Linux 5.0 kernel release.

Being well past the winter holidays, Linux 5.0-rc3 saw a ton of commit activity this week with a lot of bug/regression fixing. Though one "feature" worth pointing out that was merged this week was Nouveau now supporting the NVIDIA TU102, a.k.a. the RTX 2080 Ti and TITAN RTX granted in its mode-setting-only limited form. That complements the other NVIDIA Turing GPU support added to the Nouveau DRM driver back during the Linux 5.0 merge window to round-out the current latest-generation GeForce RTX 2000 series graphics cards.

Solving the Year 2038 problem in the Linux kernel

Filed under
Linux

Because of the way time is represented in Linux, a signed 32-bit number can't support times beyond January 19, 2038 after 3:14:07 UTC. This Year 2038 (Y2038 or Y2K38) problem is about the time data type representation. The solution is to use 64-bit timestamps.

I started working on the problem while working as an Outreachy intern for kernel developer Arnd Bergmann. Outreachy is a benevolent program that helps new programmers get into kernel development. The mentors for the kernel projects are usually experienced kernel developers like Arnd.

Booting Linux faster

Filed under
Linux

Of all the computers I've ever owned or used, the one that booted the quickest was from the 1980s; by the time your hand moved from the power switch to the keyboard, the BASIC interpreter was ready for your commands. Modern computers take anywhere from 15 seconds for a laptop to minutes for a small home server to boot. Why is there such a difference in boot times?

A microcomputer from the 1980s that booted straight to a BASIC prompt had a very simple CPU that started fetching and executing instructions from a memory address immediately upon getting power. Since these systems had BASIC in ROM, there was no loading time—you got to the BASIC prompt really quickly. More complex systems of that same era, such as the IBM PC or Macintosh, took a significant time to boot (~30 seconds), although this was mostly due to having to read the operating system (OS) off a floppy disk. Only a handful of seconds were spent in firmware before being able to load an OS.

  • Klibc Sees Its First New Release In Five Years

    Klibc has seen some new activity recently and that has resulted in the first new release to this minimal standard C library subset in a half-decade.

    Klibc 2.0.5 was released this week by Ben Hutchings following a number of commits. The previous Klibc 2.0.4 version was released in July of 2014 and since then has only been sporadic work to this library. The Klibc C library subset is principally used for early in the Linux kernel boot process / initramfs.

  • The New "TEO" CPU Idle Governor For Tickless Systems Queued Ahead Of Linux 5.1

    The new "Timer Events Oriented" (TEO) governor in development over recent months by Intel developer Rafael Wysocki is poised to land with the Linux 5.1 kernel cycle.

    The TEO governor for the CPUIdle framework is designed to be more ideal for tickless systems in more appropriately picking the best C-state for the processor/system. TEO tries to pick the deepest idle state for the system's expected conditions.

  • There's Early Stage Work Exploring Z-Wave Linux Kernel Drivers

    Z-Wave is the incredibly common wireless communication protocol at the backbone of many home automation systems. To date there hasn't been any in-kernel Z-Wave Linux kernel drivers for this low-energy mesh network standard, but a SUSE developer has prototyped an initial driver and currently exploring the in-kernel possibilities, including what could end up being a Z-Wave subsystem.

  • Kodachi 5.8 The Secure OS

    Linux Kodachi operating system is based on Debian 9.5 / Ubuntu 18.04 it will provide you with a secure, anti-forensic, and anonymous operating system considering all features that a person who is concerned about privacy would need to have in order to be secure.
    Kodachi is very easy to use all you have to do is boot it up on your PC via USB drive then you should have a fully running operating system with established VPN connection + Connection established + service running. No setup or knowledge is required from your side we do it all for you. The entire OS is functional from your temporary memory RAM so once you shut it down no trace is left behind all your activities are wiped out.
    Kodachi is a live operating system that you can start on almost any computer from a DVD, USB stick, or SD card. It aims at preserving your privacy and anonymity, and helps you to:

  • Call for testing: [Tails] 3.12~rc1

    You can help Tails! The first release candidate for the upcoming version 3.12 is out. We are very excited and cannot wait to hear what you think about it, especially the new simplified USB installation method (see below). Smile

  • Stable release: HardenedBSD-stable 12-STABLE v1200058.2
  • KookBook 0.2.0 available – now manage your cooking recipes better

    Some people have started talking about maybe translation of the interface. I might look into that in the future.

    And I wouldn’t be sad if some icon artists provided me with a icon slightly better than the knife I drew. Feel free to contact me if that’s the case.

    Happy kooking!

Security: ThreadX, Kali Linux, Rocke and Data Loss

  • Vulnerabilities Found in Highly Popular Firmware for WiFi Chips
    WiFi chip firmware in a variety of devices used mainly for gaming, personal computing, and communication comes with multiple issues. At least some of them could be exploited to run arbitrary code remotely without requiring user interaction. The security flaws were discovered in ThreadX, a real-time operating system (RTOS) developed by Express Logic. The vendor claims on their website that ThreadX has over 6.2 billion deployments, being one of the most popular software powering Wi-Fi chips. The firmware is also powering the Avastar 88W8897 SoC (Wi-Fi + Bluetooth + NFC) from Marvell, present in Sony PlayStation 4 (and its Pro variant), Microsoft Surface (+Pro) tablet and laptop, Xbox One, Samsung Chromebook and smartphones (Galaxy J1), and Valve SteamLink.
  • Wolf Halton on what’s changed in tech and where we are headed
    The tech industry is changing at a massive rate especially after the storage options moved to the cloud. However, this has also given rise to questions on security, data management, change in the work structure within an organization, and much more. Wolf Halton, an expert in Kali Linux, tells us about the security element in the cloud. He also touches upon the skills and knowledge that should be inculcated in your software development cycle in order to adjust to the dynamic tech changes at present and in the future. Following this, he juxtaposes the current software development landscape with the ideal one.
  • Rocke coinminer disables cloud protection agents
    A group of hackers that specializes in infecting servers with cryptocurrency mining software has started disabling security software agents used in cloud environments to evade detection. Known as Rocke in the security industry, the group has been active since at least April 2018 and is known for exploiting critical vulnerabilities in web application frameworks and servers like Apache Struts, Oracle WebLogic and Adobe ColdFusion.
  • Malware used by “Rocke” group evolves to evade detection by cloud security products
  • Malware uninstalls cloud security products from Linux machines
    After removing the cloud security, the malware then proceeded to mine the monero cryptocurrency on its hosts.
  • I Nearly Lost All Of My Data!

    At this point I’m really worried. You see, I cancelled my off-site Amazon Glacier backups around 6 months ago. What are the chances of both a 4 disk RAID failing AND a USB drive at the same time? Not likely, I thought. Boy was I wrong
