Since the Demise of Atom, 'Pulsar' Offers an Alternative Code Editor
by Peter Reutemann 01 Jan '24

01 Jan '24

'On December 15 GitHub declared end-of-life for its "hackable text editor" Atom. But Long-time Slashdot reader BrendaEM wants to remind everyone that after the announcement of Atom's sunset, "the community came together to keep Atom alive." First there was the longstanding fork Atom-Community. But "due to differences in long-term goals for the editor, a new version was born: Pulsar." >From the Pulsar web site: Pulsar [sometimes referred to as Pulsar-Edit] aims to not only reach feature parity with the original Atom, but to bring Pulsar into the 21st century by updating the underlying architecture, and supporting modern features. With many new features on the roadmap, once Pulsar is stable, it will be a true, Community-Based, Hackable, Text Editor. "Of course, the user interface is much of the same," writes the blog Its FOSS, and it's cross-platform (supporting Linux, macOS, and Windows). "The essentials seem to be there with the documentation, packages, and features like the ability to install packages from Git repositories..."' -- source: https://tech.slashdot.org/story/24/01/01/016215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How a Cray-1 Supercomputer Compares to a Raspberry Pi
by Peter Reutemann 01 Jan '24

01 Jan '24

'Roy Longbottom worked for the U.K. covernment's Central Computer Agency from 1960 to 1993, and "from 1972 to 2022 I produced and ran computer benchmarking and stress testing programs..." Known as the official design authority for the Whetstone benchmark), Longbottom writes that "In 2019 (aged 84), I was recruited as a voluntary member of Raspberry Pi pre-release Alpha testing team." And this week — now at age 87 — Longbottom has created a web page titled "Cray 1 supercomputer performance comparisons with home computers, phones and tablets." And one statistic really captures the impact of our decades of technological progress. "In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1."

Source-Based Gentoo Linux Goes Binary
by Peter Reutemann 01 Jan '24

01 Jan '24

'While Gentoo Linux is best-known as source-based Linux distribution, "our package manager, Portage, already for years also has support for binary packages," according to its web page. It notes that source- and binary-based package installations can be freely mixed. But now... To speed up working with slow hardware and for overall convenience, we're now also offering binary packages for download and direct installation! For most architectures, this is limited to the core system and weekly updates — not so for amd64 and arm64 however. There we've got a stunning >20 GByte of packages on our mirrors, from LibreOffice to KDE Plasma and from Gnome to Docker. Gentoo stable, updated daily. Enjoy! "We have a rather neat binary package guide on our Wiki that goes into much more detail..." the announcement points out. The packages are cryptographically signed with the same key as the stages.' -- source: https://linux.slashdot.org/story/23/12/30/1756208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Peppermint OS Builds Single-Site Browsers for Debian Systems
by Peter Reutemann 31 Dec '23

31 Dec '23

'They create a dedicated desktop icon for your favorite web-based application — a simplified browser that opens to that single URL. Yet while Linux usually offers the same functionality as other operating systems, "Peppermint OS's Ice and its successor Kumo are the only free software versions of Site-Specific Browsers available on Linux," according to Linux magazine. "Fortunately for those who want this functionality, Peppermint OS is a Debian derivative, and both can be installed on Debian and most other derivatives." Since SSBs first appeared in 2005, they have been available on both Windows and macOS. On Linux, however, the availability has come and gone. On Linux, Firefox once had an SSB mode, but it was discontinued in 2020 on the grounds that it had multiple bugs that were time-consuming to fix and there was "little to no perceived user benefit to the feature." Similarly, Chromium once had a basic SSB menu item, Create Application Shortcut, which no longer appears in recent versions. As for GNOME Web's (Epiphany's) Install Site as Web Application, while it still appears in the menu, it is no longer functional. Today, Linux users who want to try SSBs have no choices except Ice or Kumo. Neither Ice or Kumo appears in any repository except Peppermint OS's. But because Peppermint OS installs packages from Debian 12 ("bookworm"), either can be installed to Debian or a derivative... To install successfully, at least one of Firefox, Chrome, Chromium, or Vivaldi also must be installed... Because both Ice and Kumo are written in Python, they can be run on any desktop. The article concludes that Site-Specific Browsers might make more sense "on a network or in a business where their isolation provides another layer of security. Or perhaps the time for SSBs is past and there's a reason browsers have tried to implement them, and then discarded them."' -- source: https://linux.slashdot.org/story/23/12/30/0527205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox: scrollbar buttons gone
by Peter Reutemann 30 Dec '23

30 Dec '23

Hi everyone Call me old-fashioned, but I do like the arrow buttons on scrollbars. Especially on very long pages (eg OpenWRT's hardware table) where I want move the view port only a little bit... On my Linux 20.3 MATE, I managed to get them back by using these CSS settings: scrollbar { -GtkScrollbar-has-backward-stepper: true; -GtkScrollbar-has-forward-stepper: true; } In the following config file: ~/.config/gtk-3.0/gtk.css -- source: https://support.mozilla.org/en-US/questions/1420887 Also, if you don't like the thin overlay scrollbars, then set the following FF option ("about:config") to "false": widget.gtk.overlay-scrollbars.enabled Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Open Adventure (Latest Reboot Of An Ancient Classic)
by Lawrence D'Oliveiro 23 Dec '23

23 Dec '23

Just doing some random browsing on my system, and came across a Debian package called “open-adventure”. Finding my way to its home page at Eric Raymond’s site <http://www.catb.org/~esr/open-adventure/>, I discover that it is a project to modernize the source code for the original “ADVENT” game dating from 1976-1977, the one that originated the whole concept of text-based adventure games. The original code was written in Fortran; this one rewrites it all in clean, almost-idiomatic C (as opposed to automatically-translated GOTO-ridden C), and incorporates such innovations as using YAML as the source code for the maze format (translated to C structures at build time). It has been carefully regression-tested against the Fortran original(s) to ensure the gameplay is identical (and the few conscious deviations can be disabled if you want). The developers also kept in mind the possibility of porting the code further, to more modern languages like Python or Go. In the meantime, they have declared the project “finished” as of earlier this year, with all known bug reports closed and all compatibility tests passed.

LMDE
by john 21 Dec '23

21 Dec '23

After enduring a few minor health issues over the past months I have finally got round to installing Linux Mint Debian edition 5 Bullseye. I think due to the Cinnamon Desktop environment it is marginally slower than the Mate DE I was using with my Ubuntu Jammy Jellyfish distribution. I didn't find the minor difference to be any problem for me. I am well pleased with the performance, look and feel of it and have not (so far) found anything unpleasant or difficult. It appears to me to be well suited to a first time user or for someone migrating from Windows. Cheers John..

Fedora Asahi Remix Officially Released For Apple Silicon Macs
by Peter Reutemann 21 Dec '23

21 Dec '23

'9to5Linux: Announced in early August and initially planned for the end of the month, the Fedora Asahi Remix distribution is finally here for those who want to install the Fedora Linux operating system on their Apple Silicon Macs. Previously a remix of Arch Linux ARM, the Fedora Asahi Remix distribution is the result of a multi-year collaboration between the Asahi Linux project and the Fedora Project, enabling you to have a proper daily driver on your Apple Silicon Mac thanks to Fedora Linux's excellent 64-bit ARM support. The distro is based on the latest Fedora Linux 39 release and ships with the KDE Plasma 5.27 LTS desktop environment by default, using Wayland. This promises a smooth Linux desktop experience on Apple hardware similar to macOS. Fedora Asahi Remix also comes with XWayland for those who want to run X11 apps. In addition, it features non-conformant OpenGL 3.3 support including GPU-accelerated geometry shaders and transform feedback, PipeWire by default with WirePlumber, as well as the Calamares graphical installer.

SSH protects the world’s most sensitive networks. It just got a lot weaker
by Peter Reutemann 20 Dec '23

20 Dec '23

'Named Terrapin, the new hack works only when an attacker has an active adversary-in-the middle position on the connection between the admins and the network they remotely connect to. Also known as a man-in-the-middle or MitM attack, this occurs when an attacker secretly positioned between two parties intercepts communications and assumes the identity of both the recipient and the sender. This provides the ability to both intercept and to alter communications. While this position can be difficult for an attacker to achieve, it’s one of the scenarios from which SSH was thought to have immunity. For Terrapin to be viable, the connection it interferes with also must be secured by either "ChaCha20-Poly1305" or "CBC with Encrypt-then-MAC," both of which are cipher modes added to the SSH protocol (in 2013 and 2012, respectively). A scan performed by the researchers found that 77 percent of SSH servers exposed to the Internet support at least one of the vulnerable encryption modes, while 57 percent of them list a vulnerable encryption mode as the preferred choice. At its core, Terrapin works by altering or corrupting information transmitted in the SSH data stream during the handshake—the earliest stage of a connection, when the two parties negotiate the encryption parameters they will use to establish a secure connection. The attack targets the BPP, short for Binary Packet Protocol, which is designed to ensure that adversaries with an active position can't add or drop messages exchanged during the handshake. Terrapin relies on prefix truncation, a class of attack that removes specific messages at the very beginning of a data stream.' -- source: https://arstechnica.com/security/2023/12/hackers-can-break-ssh-channel-inte… This SUSE knowledge base entry lists some configuration changes that one can apply (section "Additional Information"): https://www.suse.com/de-de/support/kb/doc/?id=000021295 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 121 Now Available With Wayland Enabled By Default
by Peter Reutemann 19 Dec '23

19 Dec '23

'Firefox 121 has arrived with Wayland support to be used by default on modern Linux desktops. Phoronix's Michael Larabel writes: Some Linux distributions and package builds have been using the native Wayland path for a while but now it's great to see the upstream builds make this default change as we get ready to embark on the 2024 Linux desktop. With my testing of Firefox 121 on Wayland, it's been working out well. X.Org/X11 support remains in place for those not using a Wayland-based desktop environment. Firefox 121 also adds Voice Control command support on macOS, adds an option to always force-underline links within websites, Firefox now includes a floating button to help in creation within PDFs, various CSS feature additions, and other developer enhancements. Firefox 121 also now supports tail call elimination in WebAssembly for enhancing support for functional languages.
