I am happy to announce a new release of GNU poke, version 2.4.

This is a bugfix release in the poke 2.x series.

See the file NEWS in the distribution tarball for a list of issues fixed in this release.

The tarball poke-2.4.tar.gz is now available at

https://ftp.gnu.org/gnu/poke/poke-2.4.tar.gz.

> GNU poke (http://www.jemarch.net/poke) is an interactive, extensible editor for binary data.  Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.

Happy poking!

Here are the highlights:

• Support for Angular standalone components
• Updates for Vue 3
• TypeScript 4.7 support
• Built-in remote development workflows
• Bundled JetBrains Space integration
• Font size indicator on zooming
• A new way to run the current file

NsCDE is a retro but powerful UNIX desktop environment which resembles CDE look (and partially feel) but with a more powerful and flexible framework beneath-the-surface, more suited for 21st century unix-like and Linux systems and user requirements than original CDE. NsCDE can be considered as a heavyweight FVWM theme on steroids, but combined with a couple other free software components and custom FVWM applications and a lot of configuration, NsCDE can be considered a lightweight hybrid desktop environment. It also contains themes for Qt, Gtk, and more, to ensure a consistent CDE look and feel. NsCDE 2.2 has just been released, and it contains a ton of improvements. This is such a cool and fascinating project.

In Ruby and Rails, there is no class dedicated to time-of-day, so 2000–01–01 is used for the time. ActiveModel implements a Time class to reflect the database type of time https://nauman.medium.com/rails-time-without-time-zone-50d690d45f82

With the addition of the developer-generated Data safety section this year, Google Play removed the old list of app permissions. The Play Store is now reversing this decision in response to user feedback and will have both coexist. This was a baffling decision to begin with – the Data safety section relied on developers being honest and truthful about their privacy practices and permissions usage, which was never going to work out with the amount of downright scams and sleaziness targeting children that are in the Play Store (and App Store).

GNU Parallel 20220722 (‘Roe vs Wade’) has been released. It is available for download at: lbry://@GnuParallel:4

Quote of the month:

  The syntax for GNU Parallel is so slick that I often use it just to make my script read nicer, and the parallelism is a cherry on top.

GNU Parallel – For people who live life in the parallel lane.

If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.

About GNU Parallel

GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.

If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.

GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.

For example you can run this to convert all jpeg files into png and gif files and have a progress bar:

  parallel –bar convert {1} {1.}.{2} ::: *.jpg ::: png gif

Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:

  find . -name ‘*.jpg’ |

    parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: – ::: 50 100 200

You can install GNU Parallel in just 10 seconds with:

About GNU SQL

GNU sql aims to give a simple, unified interface for accessing databases through all the different databases’ command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.

The database is addressed using a DBURL. If commands are left out you will get that database’s interactive shell.

About GNU Niceload

GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.

The most interesting addition we’ve seen in a while is rolling out to users on the experimental Dev Channel now: a modified version of the taskbar with much-improved handling of app icon overflow when users have too many apps open at once. Click an ellipsis button on your taskbar, and a new icon overflow menu opens up, allowing you to interact with any of those extra icons the same way you would if they were sitting on the taskbar. This would be a big improvement over the current overflow behavior, which devotes one icon’s worth of space to show the icon for the app you last interacted with, leaving the rest inaccessible. That icon will continue to appear on the taskbar alongside the new ellipsis icon. Microsoft says that app icons in the overflow area will be able to show jump lists and other customizable shortcuts the same as any other app icon in the taskbar. Nice little change, but it seems rather telling that they only got to this now.
