  • Linux 5.10 Solves the Year 2038 Problem Till Year 2486

    The Year 2000 problem was one of the most severe issues in programs of computerized systems that created havoc in computers and affecting systems worldwide. A little background on why this problem emerged — Ever noticed when a computer or a website asks you to enter the last two digits of the year?

    Computers are programmed to store only the last two digits of years because it saves storage space (Four digits Vs. Two digits). Say there’s only one day left in the year 1999 (99); a day later, the systems would fail to understand if it’s the Year 2000 (00) or 1900 (00).

  • Linux 5.9.1 And Older Stable Kernel Updates Fixing "Bleeding Tooth" Bluetooth Vulnerability Are Available - LinuxReviews

    BleedingTooth is a really bad and in theory very serious Linux kernel vulnerability. It allows someone within Bluetooth range to potentially execute code on your Linux machine thanks to a combination of improper input validation, improper buffer restrictions and improper access control in the BlueZ libraries and heap-based type confusion in the Linux kernel's L2CAP code. The practical threat isn't all that.

    Linux 5.9.1 as well as updates to the older "stable" kernel series (5.8.16, 5.4.72, 4.19.152, 4.14.202, 4.9.240, and 4.4.240) have been released with a patch by Intel's Luiz Augusto von Dentz addressing the Linux kernel side of the BleedingTooth vulnerability. You should upgrade to one of those if your machine has a Bluetooth adapter (most laptops do).

  • Char/Misc With Linux 5.10 Brings Nitro Enclaves, Alder Lake, More Code For Gaudi - Phoronix

    The "char/misc" area within the Linux kernel continues to have a bit of everything as the "catch all" pull request of the kernel not fitting into other existing subsystems. 

    [...]

    - Qualcomm's MHI bus added in Linux 5.7 supports more features with Linux 5.10 albeit mostly lower-level changes. 

    - The Intel-owned Habana Labs continues working extensively on their upstream kernel driver supporting their AI inference and training accelerators. With Linux 5.10 is a wide range of improvements to the Habana Labs kernel code largely on the Gaudi side. 

    - The SoundWire code has gained support for run-time power management, including within the Intel SoundWire support paths. The Intel code also adds multi-link support and other improvements.

  • Linux 5.10 Continues Bringing Up Support For Intel's Rocket Lake - Phoronix

    Building off Linux 5.9 that featured initial support for Gen12 graphics on next year's Rocket Lake desktop platform along with other early enablement for Rocket Lake like RAPL support and other PCI ID additions, that work has continued for the Linux 5.10 cycle. 

    The libata pull adds Rocket Lake PCH-H RAID PCI IDs as one of the additions. 

    There is also the platform-drivers-x86 work for Linux 5.10 where Rocket Lake support is added to the intel_pmc_core driver. 

    While the DRM code in Linux 5.9 brought initial support for Rocket Lake building off the existing Gen12 code, the DRM code for Linux 5.10 also has necessary code changes for properly driving displays with the hardware. 

Relax, The Computing World Won’t End In 2038.

  • Relax, The Computing World Won’t End In 2038. But 2486 Is Looking Grim

    A looming problem with Linux-based computers being unable to handle dates beyond the year 2038 appears to have been solved - or at least punted into the distant future.

    In a similar vein to the infamous Millennium Bug, where computers using two digits to denote years were unable to handle the fallover into the year 2000, Linux-based systems were facing a comparable issue on 03:14:07 UTC on January 19, 2038.

    This time the problem was being caused by Linux computers counting the time in seconds, starting from January 1, 1970. On that fateful date in January 2038, the number of seconds would have exceeded the value that could be stored in a single 32-bit integer, causing computers to lose track of time.

  • Capturing Decrypted TLS Traffic with Arkime - NETRESEC Blog

    The latest version of Arkime (The Sniffer Formerly Known As Moloch) can now be fed with a real-time stream of decrypted HTTPS traffic from PolarProxy. All that is needed to enable this feature is to include "pcapReadMethod=pcap-over-ip-server" in Arkime's config.ini file and start PolarProxy with the "--pcapoveripconnect 127.0.0.1:57012" option. PolarProxy will then connect to Arkime's PCAP-over-IP listener on TCP port 57012 and send it a copy of all TLS packets it decrypts.

  • How to rebalance your btrfs filesystem on your Linux data center servers - TechRepublic

    The btrfs file system is quickly becoming more widespread. It's used on a number of Linux distributions and offers plenty of features that make sense in a data center environment--features like snapshots, load balancing, online defragmentation, pooling, and error detection. To get the most out of the btrfs file system, you're going to need to know how to use some of the more advanced features. One such feature is called balancing (or rebalancing).

  • How To Install AnyDesk on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install AnyDesk on Ubuntu 20.04 LTS. For those of you who didn’t know, AnyDesk is the world’s most comfortable remote desktop application. Access all your programs, documents, and files from anywhere, without having to entrust your data to a cloud service. You can say it’s an alternative to the TeamViewer, which is available free. Anydesk provides a faster remote connection than any other existing remote desktop application. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of AnyDesk Remote Desktop on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian based distribution like Linux Mint.

Games: Stadia, Godot Engine and More

  • Six new games live for Stadia Pro, Super Bomberman R Online now free to play + more | GamingOnLinux

    If it's not clear yet - Stadia Pro is an entirely optional subscription. You get to claim and keep free games, as long as your subscription remains active. If you stop it, you lose those games until you subscribe again and then you get them back - it works like PSPlus on the PlayStation. Otherwise, you buy games from Stadia like any other store. You can also now play Super Bomberman R Online, the 64 player Battle Royale game completely free to play on Stadia. That's now the second free to play game following Destiny 2 going free on Stadia back in November. Giving you another easy game to try the service with which is what it has been lacking.

Making the Switch to elementary OS

It all started with an upgrade. In October, 2020 version 20.10 of Ubuntu came out. As I usually do, I duly clicked the button to start the process. That upgrade seemed to go smoothly — everything installed quickly with no conflicts or error messages. I walked away to make a cup of white tea, and when I came back the installation had finished and my laptop rebooted. It was then that I noticed a problem. A fairly big one. Instead of a login screen, I saw a field of aubergine (the colour, not the vegetable). I thought that my laptop was sleeping, so I pressed some keys to try to wake it up. It didn't work. I rebooted, but I was faced with the same problem. Read more

Want to jump-start a proof of concept? Not sure what integration capabilities you’ll need? IBM, working closely with our partners at AWS, makes it easy with the Quick Start for IBM Cloud Pak for Integration on AWS. Employing best practices from both IBM and AWS, you can deploy a full range of integration capabilities in a production-grade multi-availability zone topology with a single click. So, jump in and start experimenting with different integration patterns that can help facilitate your transition to hybrid cloud.
