This PowerShell script uses the systeminfo command to produce an HTML report (sample) containing system information. It also calculates the system's uptime. By default, only a subset of attributes from systeminfo are included in the report. To include more, simply modify the following line:
$attrs = 'System Model:', 'System Manufacturer:', 'OS Name:', 'OS Version:', 'System Boot Time:', 'Total Physical Memory:', 'Available Physical Memory:'
In the example below, the script generates a file called report.html. If no output filename is specified, the script generates output.html.
pwsh ./sysinfoweb.ps1 report.html

I recently upgraded my TeX Live installation from 2024 to 2025. My method differs slightly from the upgrade instructions on the TeX Live web site, but I've had no issues doing it this way the past few years. Rather than copying the installation to a new directory, I simply move it (I have limited space on my Linux VM and the TeX Live install is nearly 12 gigabytes). To start:
cd /usr/local/texlive
sudo mv 2024 2025
Next, modify paths to reflect the location of TeX Live to /usr/local/2025. For me, this means modifying my .bashrc and using visudo to update the path for sudoers.
Now, download the update-tlmgr-latest.sh script provided on the upgrade instructions page, make it executable, and run it.
Finally, upgrade as usual using sudo tlmgr update --list and sudo tlmgr update --all. That's it, you're done!

Hua has an "orphans" mode that enables the identification of files that exist in the output directory but not in the entries file. Here's an example using the sample content files:
$ pwsh hua.ps1 example.cfg -O
orphan-1.html
As there may be perfectly valid reasons for the file to exist (e.g., a file referenced in generated content like a PDF or a download) Hua takes no action beyond listing the orphan filename.
It occurred to me this mode could also be used to look for orphans in the content directory. All that's required is to change the output_dir variable value in the Hua config file to the location of the content directory. In the example.cfg file change this:
...
output_dir = .\blog
...
to this:
...
output_dir = .\content
...
and run Hua in the same way as above. Content is not processed in orphans mode. Don't forget to change output_dir to its prior value!

My Rexx-based running statistics generator now features an HTML output mode. It's invoked in the following manner:
regina rs.rex data.csv 24 jun html 1 June 2024 Running Statistics > html/sample-month.html
The example above outputs statistics for June 2024. html refers to the output mode (the other option is txt). 1 specifies the scale which effects the length of the distance profile bars (useful for year-long reports such as shown below).
regina rs.rex data.csv 24 - html .66 2024 Running Statistics > html/sample-year.html
The latest package contains sample reports for month and year as well as styles (light and dark versions).

A Hua tar archive is now available for Linux hosts. It is designed to be installed in /usr/local. An executable shell script is included (hua) as well as a man page.
Like the zip version, it includes a sample web site. To try it out, run the following:
$ mkdir temp
$ cd temp
$ cp /usr/local/share/hua/example.cfg .
$ cp -r /usr/local/share/hua/content .
$ mkdir blog
$ hua example.cfg
The installation looks like this:
\---usr
\---local
+---bin
| hua
| hua-paging.ps1
| hua.ps1
|
\---share
+---hua
| | entries.csv
| | example.cfg
| | Hua.pdf
| | meta.csv
| | MIT-License.txt
| |
| +---content
| | | another.html
| | | first.html
| | | latest.html
