Finally recorded a presentation about Sitepress at https://youtu.be/K2N8fp2P7Ms where I cover my motivations for building Sitepress eight years ago and show how I created the Rails docs for Terminalwire at https://terminalwire.com/docs/rails with Markdown templates, Fromtmatter, and page models.

The first RC build for the FreeBSD 14.2 release cycle is now available. ISO images for the amd64, i386, powerpc, powerpc64, powerpc64le, powerpcspe, armv7, aarch64, and riscv64 architectures are FreeBSD mirror sites.

GNU Parallel 20241122 (‘Ahoo Daryaei’) has been released. It is available for download at: lbry://@GnuParallel:4

Quote of the month:

  GNU parallel is so satisfying

    — James Coman @jcoman.bsky.social

New in this release:

• –pipe –block works similar to –pipepart –block if –block size is negative.
• DBURLs can be written with / instead of %2F for sqlite and CSV.
• Bug fixes and man page updates.

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

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.

This is a Silicon Graphics workstation from 1995. Specifically, it is an ‘Teal’ Indigo 2 (as opposed to a ‘Purple’ Indigo 2, which came later). Ordinarily that’s rare enough – these things were about £30,000 brand new. A close look at the case badge though, marks this out as a ‘Teal’ POWER Indigo 2 – where instead of the usual MIPS R4600 or R4400SC CPU modules, we have the rare, unusual, expensive and short-lived MIPS R8000 module. ↫ Jonathan Pallant It’s rare these days to find an article about exotic hardware that has this many detailed photographs – most people just default to making videos now. Even if the actual contents of the article aren’t interesting, this is some real good hardware pornography, and I salute the author for taking the time to both take and publish these photos in a traditional way. That being said, what makes this particular SGI Indigo 2 so special? The R8000 is not a CPU in the traditional sense. It is a processor, but that processor is comprised of many individual chips, some of which you can see and some of which are hidden under the heatsink. The MIPS R8000 was apparently an attempt to wrestle back the Floating-Point crown from rivals. Some accounts report that at 75 MHz, it has around ten times the double-precision floating point throughput of an equivalent Pentium. However, code had to be specially optimised to take best advantage of it and most code wasn’t. It lasted on the market for around 18 months, before bring replaced by the MIPS R10K in the ‘Purple’ Indigo 2. ↫ Jonathan Pallant And here we see the first little bits of writing on the wall for the future of all the architectures trying to combat the rising tide of x86. SGI’s MIPS, Sun’s SPARC, HP’s PA-RISC, and other processors would stumble along for a few more years after this R8000 module came on the market, but looking back, all of these companies knew which way the wind was blowing, and many of them would sign onto Intel’s Itanium effort. Itanium would fail spectacularly, but the cat was out of the bag, and SGI, Sun, and HP would all be making standard Xeon and Opteron workstations within a a few years. Absolutely amazing to see this rare of a machine and module lovingly looked after.
