Somewhere in the drafts was a note to refer to an old Chris Bensen blog post on the Embarcadero server: blogs.embarcadero.com/cbensen/2005/12/07/22388
Alas, a lot of Embarcadero stuff is gone, some because of Idera not caring, others because as of Codegear, the team never was good at keeping infrastructure alive, nor cater for proper archiging at the Wayback Machine.
Luckily, the Borland days were different, as I found by browsing web.archive.org/web//http://blogs.borland.com/: almost 10k archived pages!
Searching for cbensen or 22388 then got me the actual post [Wayback/Archive] Delphi 2006 Hidden COM Registry Entries (the last link is dead, the others not indexed by search engines) and quoted below while adding some formatting: Read the rest of this entry »

I found [Wayback/Archive] DB Browser for SQLite via [Wayback/Archive] In z’n leren frakske | Tech45 Podcast (thanks [Wayback/Archive] Toon Van de Putte (@toonvandeputte)!).
It is a standalone reasonably sized database browser for the single-process SQLite database (which is itself a file storage replacement for highly table structured data, see below).
With SQLite gaining more and more popularity in standalone application usage (you can even host it inside a web browser session!), I bump in it more often to fix things (more on that in a future blog post), which means that besides the standard console support in SQLite, having a versatile browser is really useful.
DB Browser for SQLite, or in short sqlitebrowser, fulfills that need better than I expected. It’s cross-platform so it works on Mac OS, Windows and Linux (and sort of on WSL2 on Windows, see links below).
Hopefully I can show you how I used it in future blog-posts. For now, and for my link archive, below are just some links to get started.
Oh and the comment: as always with files containing structured data that is randomly accessed you should be really careful when opening them over file-shares or virtual drives like cloud storage.

In the past, I used to modify /etc/sysconfig/named and add entries to the NAMED_CONF_INCLUDE_FILES setting, then run /usr/share/bind/createNamedConfInclude
to generate /etc/named.conf.include.
As of OpenSuSE 15.4, /usr/share/bind/createNamedConfInclude has become an empty file and NAMED_CONF_INCLUDE_FILES got removed and NAMED_INITIALIZE_SCRIPTS introduced.
So now I changed my playbooks to manually generate /etc/named.conf.include and include it form /etc/sysconfig/named.
Since I hardly perform these new installations, it took a few years for me to find out about this change. Upgrading existing systems somehow kept the generated file and included it.
Related links with quotes as it was hard to find out what changed and how to work around and I wasn’t the only one bump into issues:

Voor mijn link archief: links rondom Busch-Jaeger – 6815U schakelmateriaal (comfort, IR) via [Wayback/Archive] busch jaeger 6815 – Google Search..
Doet officieel geen LED en spaarlamp, maar schijnt meestal wel te werken. Hopelijk is dit een opstap voor schakelmateriaal wat altijd met LED en spaarlamp werkt.
Het grote voordeel van deze schakelaars plus bijbehorende functie-kapjes is dat ze tegelijk op IR+tijd en handmatig kunnen werken. Dus vanzelf aan/uit met IR+tijd, maar ook handmatig aan/uit zetten of combinaties.

[Wayback/Archive] One-liner for running queries against CSV files with SQLite | Simon Willison’s TILs
I figured out how to run a SQL query directly against a CSV file using the sqlite3 command-line utility:
sqlite3 :memory: -cmd '.mode csv' -cmd '.import taxi.csv taxi' \
'SELECT passenger_count, COUNT(*), AVG(total_amount) FROM taxi GROUP BY passenger_count'
This uses the special :memory: filename to open an in-memory database. Then it uses two -cmd options to turn on CSV mode and import the taxi.csv file into a table called taxi. Then it runs the SQL query.
sqlite3 :memory: -cmd '.import -csv taxi.csv taxi' \
'SELECT passenger_count, COUNT(*), AVG(total_amount) FROM taxi GROUP BY passenger_count'

[Wayback/Archive] How TINY Can I go? The BEST Power Board is here! – YouTube – GreatScott!
I will try to remake an AliExpress PCB. It is a very handy voltage converter that can take a varying battery voltage and convert it into 3.3V or 5V while only requiring very little current (25uA) on the input. Sounds awesome, but the board is way too huge. That is why I try to push the size limits in this video to the minimum.

A while ago, I needed to investigate reboot events on some Windows 10 systems. I wanted to use the console instead of the eventvwr GUI Event Viewer.
There is a tool for that called wevtutil which – like eventvwr – uses XPath query parameters and produces XML output.
Postprocessing XML can be a thing, but since .NET has great XML support, you can use PowerShell for that (which for me often is way easier than going the XSLT route, for instance because Windows lacks built-in console XSLT tooling).
Based on the help and the below links, my query command then on these machines turned out to be this: Read the rest of this entry »

Waar velen al over waarschuwden gebeurt ook in het Nederlandstalige gebied: AI-gegenereerde web-pagina’s komen hoog in de zoekresultaten en vervuilen daarmee Large Language Models van nieuwe AI-tools.
Voorbeelden die ik tegenkwam:
Ze zijn echt heel makkelijk te ontkrachten, ondanks dat de tekst er heel mooi en netjes uitziet: de inhoud klopt gewoon, en juist dat de tekst er zo mooi en netjes uitziet maakte het voor mij verdacht.
De eerste site is het oude domain van [Wayback/Archive] Baarnse Onafhankelijke Partij wat al heel snel na het opheffen van die partij (zie Baarnse Onafhankelijke Partij – Wikipedia) werd overgenomen.
De domains behoren beide tot SEO sites.
Queries die zowel laten zien hoe hoog sommige pagina’s komen als hoe eenvoudig hun inhoud te ontkrachten is:

From a long time ago, but the (impressive!) leaderboard still has the same order (the Rust implementation did get faster!).
[Wayback/Archive] Towards Inserting One Billion Rows in SQLite Under A Minute – blag
Recently, I ran into a situation where I needed a test database with lots of rows and needed it fast. So I did what any programmer would do: wrote a Python script to generate the DB. Unfortunately, it was slow. Really slow. So I did what any programmer would do: went down the rabbit hole of learning more about SQLite, Python, and eventually Rust… in my quest to get a 1B row database under a minute. This blog post is a summary of this fun and educational exercise.
