As written in Generate RSS from Markdown extracting RSS from Markdown with frontmatter is simple. Now I took a slightly different approach and generate RSS from the HTML files directly.
For this blog I still want an RSS feed. Simplified Saaze does not provide this functionality. Simplified Saaze as…

End of May 2021 I moved my blog from WordPress to self hosted, see Moved Blog To eklausmeier.goip.de. Now after roughly half a year I regained ca. half of the visitors I had on WordPress. Contrary to some murky SEO advice Google does not honor "noindex". I have below HTML code in all my…

When you have a blog you might want to engage with your readers by allowing them to comment on your posts. WordPress allows this out of the box. But when using a static site generator then having a commenting system is a bit more difficult. Many have resorted to Disqus. But Disqus has a number of…

Internet adoption rates are phenomenal. I already mentioned in India is now the third largest Smartphone market in the world - Android Authority the massive growth in India.
Above graphs are from Our World in Data: Technology Adoption written by Hannah Ritchie and Max Roser.

1. Problem statement. When you run a web-server on your machine many bots and crawlers will visit. When analysing how many "real" visitors you have, you should therefore suppress these entries in your analysis from your log file of the web-server.
This blog is served by Hiawatha…

Hiawatha is a secure and reliable web-server. It is used for this blog. AWStats is a collection of Perl-scripts to analyze log-files from web-servers. By default, AWStats can read Apache log-files. It cannot directly read log-files from Hiawatha.
The Hiawatha log-file format is:
host, this is the…

In trying to decrease load times of this blog, I noticed that the prism.js library requires quite a number of requests to the unpkg-server. So I tried to combine all these requests into only two. The results are quite impressive.
I compared various measurements using tools.pingdom.com.

Zola is a static site generator written in Rust. Hugo is a static site generator written in Go. Simplified Saaze, Saaze for short, is written in PHP.
Task: Compare run times of Saaze vs. Hugo vs Zola. I didn't find a direct comparison so far. There is a comparison of Eleventy vs. Gatsby vs. Hugo…

I already described some changes I made to the original Saaze software:
Moved Blog To eklausmeier.goip.de
Calling MD4C from PHP via FFI
Considerations Regarding Simplifications of Saaze
Profiling PHP Programs
In Making Static Site Generator 30-Times Faster I already described that removing…

Task at hand: You receive daily reports with attachments, which you need to analyze programmatically. Therefore you want those attachments in your filesystem. You need an Outlook macro, which saves all those attachments to a directory. Outlook VBA to the rescue.
Below macro processes all e-mails…

Sometimes you have to copy whole directories recursively to an FTP-server. Many FTP servers are not able to handle bulk uploads directly. Here lftp comes to the rescue. lftp allows to upload or download entire directories irrespective of the capabilities of the FTP server.
Assume we want to upload…

Static site generators take Markdown files as input and generate HTML files. This way, when the end-user visits a web-site, all pages are already generated, and the web-server serves just plain HTML. No database is needed, no server-side script language is required. Two main advantages are easy to…

Profiling a program is the process to measure how much CPU time a function uses, and also to count how many times this function was called.
One very powerful profiler for PHP, XHProf, was initially developed by Facebook engineers. Facebook formerly used PHP very intensively.

PECL is the PHP Extension Community Library. These extensions are written in C. Symfony is a PHP web application framework written in PHP.
Initially I just wanted to reduce the dependencies in Saaze, so I installed PECL PHP package yaml. When I compared run-times between the original,…

When I ran the n-queens problem in COBOL using GnuCOBOL I was a little bit surprised how slow the resulting program was -- it was slower than the equivalent PHP program. Therefore I installed the IBM COBOL for Linux compiler on the same machine and compared performance, see Installing IBM COBOL for…

Task at hand: Install the 60-day trial of "IBM COBOL for Linux" on Arch Linux.
1. Download. Downloading the compiler is at IBM COBOL for Linux on x86 60-day Trial.
2. Unpacking. Downloaded file is marked as gzipped tar, but in actuality it is just a tar file:

When compiling GnuCOBOL from source this works without any hiccups. The usual configure, make sequence. I had written on this in Generating JSON with COBOL. But if you run make check you might encounter multiple check-failures when run after makepkg. The reason is that makepkg introduces a couple…

Task at hand: Process ca. 400,000 files. In our case each file needed to be converted from EBCDIC to ASCII.
Obviously, you could do this sequentially. But having a multiprocessor machine you should make use of all processing power. The chosen approach is as follows:
Generate a list of all files to…
