  • Persistent Live USB vs. Full Linux install on a USB drive | FOSS Linux

    Live USB is a fascinating way of testing out any Linux distro without modifying or making changes to your computer. Unknown to many, there is data persistency mode in the Live session. So you can make some changes and save the file to your Universal Serial Bus (USB) drive. The data will remain still even after powering off the live session.

    You can run a test drive on installing the distro to your USB drive after testing out the live session instead of the internal hard drive. Accordingly, there are two more test-driving a Linux distro – Persistent Live USB drive and Full distro install USB drive.

    The two methods will still allow you to boot Linux from a USB drive and save your data. Some may be thinking about the differences between the two methods and which one you should opt for.

  • How to Transfer Files Between Linux, Android, and iOS Using qrcp

    File-sharing apps make it easier to transfer files between mobile devices and computers. But while these apps generally work well, they tend to cause compatibility issues with certain platforms owing to their limitations.

    This is where qrcp comes in. Qrcp is a file transfer utility that works via the terminal and relies on Wi-Fi to carry out file transfer. As a result, you can use it to share files between any computer and mobile phone, irrespective of their operating systems.

    Here's a guide detailing qrcp and the steps to use it for transferring files between your Linux computer and a mobile device.

  • How to Set Date and Time on Rocky Linux 8 Desktop and Server

    Here are the two ways to set a date and time on Rocky Linux 8 or AlmaLinux using the command terminal and graphical user interface.

    There are many processes on the Linux operating system that requires the correct system date and time. Also, to update the system properly and other processes like cronjobs we must need the up-to-date time & date. However, Linux or any other OS automatically syncs the system time from the server, in case not or you want to change the timezone manually then let’s explore how to do that.

  • Linux Fixes Spectre V1 SWAPGS Mitigation After Being Partially Borked Since Last Year - Phoronix

    This week's set of "x86/urgent" changes for the Linux 5.16-rc4 kernel due out later today has some Spectre V1 fixes after kernel commits last year ended up partially messing things up around its SWAPGS handling. These fixes in turn will also likely be back-ported to relevant stable kernel series. Thanks to an Alibaba engineer, Lai Jiangshan, are some important fixes around the Spectre V1 SWAPGS mitigation that are landing today in the mainline kernel.

  • Reproducible Builds: Reproducible Builds in November 2021

    As a quick recap, whilst anyone may inspect the source code of free software for malicious flaws, almost all software is distributed to end users as pre-compiled binaries. The motivation behind the reproducible builds effort is therefore to ensure no flaws have been introduced during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised. If you are interested in contributing to our project, please visit our Contribute page on our website.

  • Reproducible Builds (diffoscope): diffoscope 195 released

    The diffoscope maintainers are pleased to announce the release of diffoscope version 195. This version includes the following changes:

    [ Chris Lamb ]
    * Don't use the runtime platform's native endianness when unpacking .pyc
      files to fix test failures on big-endian machines.
    

Linux 5.16-rc4

Fairly small rc4 this week. Three areas stand out in the diff: some
kvm fixes (and tests), network driver fixes, and the tegra SoC sound
fixes.

The rest is fairly spread out: drm fixes, some filesystem stuff,
various arch updates, and some smattering of random driver fixes.

Nothing looks all that scary, although I certainly hope the kvm side
will calm down.

EFF Argument in Patent Troll Case to Be Livestreamed on Monday

At 10 am Monday, FOSS folks and others interested in software patent litigation will have a chance to have a firsthand look at how our courts address patent cases. The case involves a “notorious patent troll,” according to Electronic Frontiers Foundation, that is trying to hide information from Apple, which it’s suing. “At a federal appeals court hearing that will be livestreamed, attorney Alexandra H. Moss, Executive Director at Public Interest Patent Law Institute, who is assisting EFF in the case, will argue that a judge’s order to unseal all documents and preserve public access in the case of Uniloc USA, Inc. v. Apple Inc. should be upheld,” EFF said in a statement on Thursday. “Uniloc is entitled to resolve its patent dispute in publicly-funded courts, Moss will argue, but it’s not entitled to do so secretly.” EFF said that this is the second time the plaintiff, Uniloc, has appealed an order to be more transparent in this case.

Gnuastro 0.16 released

Dear all,

I am happy to announce the 16th official release of GNU Astronomy
Utilities (Gnuastro version 0.16).

Gnuastro is an official GNU package, consisting of various
command-line programs and library functions for the manipulation and
analysis of (astronomical) data. All the programs share the same basic
command-line user interface (modeled on GNU Coreutils). For the full
list of Gnuastro's library, programs, and a comprehensive general
tutorial (recommended place to start using Gnuastro), please see the
links below respectively:

https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html

For a complete review of the new/changed features in this release,
please see [1] below (also available in the 'NEWS' file within the
source code tarball).

Here is the compressed source and the GPG detached signature for this
release. To uncompress Lzip tarballs, see [2]. To check the validity
of the tarballs using the GPG detached signature (*.sig) see [3]:

  https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.16.tar.lz    (3.7MB)
  https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.16.tar.gz    (5.9MB)

  https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.16.tar.lz.sig (833B)

Here are the SHA1 and SHA256 checksums (other ways to check if the
tarball you download is what we distributed). Just note that the
SHA256 checksum is base64 encoded, instead of the hexadecimal encoding
that most checksum tools default to.

  Autoconf 2.71
  Automake 1.16.4
  Help2man 1.48.5

The dependencies to build Gnuastro from this tarball on your system
are described here:
