A ton of keyboard conversions via GitHub – trekawek/mac-plus-ps2: Arduino project that allows to connect a PS2 keyboard to Macintosh Plus

Posted by jpluimers on 2025/12/12

This is for earliest compact Apple Macintosh systems predating the introduction ADB (Apple Desktop Bus) on Macintosh SE and Apple Macintosh II (and Apple IIgs which technically is not a Macintosh):

[Wayback/Archive] GitHub – trekawek/mac-plus-ps2: Arduino project that allows to connect a PS2 keyboard to Macintosh Plus

Before continuing to an even more impressive keyboard and mouse interfacing project below (basically many kinds of modern keyboard, mice and gamepads to many retro computers) that I found thanks to doing some more research after finding the above one, lets summarise where the above one is still useful for:

Memory Bandwidth Per Core and Per Socket for Intel Xeon and AMD EPYC

Posted by jpluimers on 2025/12/12

I wonder if this has changed over the last few years since this got published early 2023: [Wayback/Archive] Memory Bandwidth Per Core and Per Socket for Intel Xeon and AMD EPYC

While we are looking at bandwidth per core, the performance per core has increased by 2.5-3x over the past decade.

Wat notities over het CDN wat de NPO gebruikt voor podcasts

Posted by jpluimers on 2025/12/11

Nog. niet gecontroleerd, maar wellicht werkt dit ook voor (fragmenten van) radiouitzendingen?

Uit een draad over het liedje “Met puntjes” van Joke Bruijs die een paar maanden terug enkele dagen na haar boezem vriend en ex-man Gerard Cox overleed¹.

Ionica Smeets schreef over het liedje op Mastodon², maar de link naar de audio van de podcast [Wayback/Archive] Andermans Veren – Beluister Andermans Veren zondag 14 januari 2018 | Podcasts | NPO Radio 5 verdween al snel.

Omdat ik al eerder een probleem had met de audio van [Wayback/Archive] Keihard de Beste – NPO Podcast te downloaden, dook ik in de CDN die de NPO gebruikt.

De archivers hadden er wat problemen mee dus het staat in 2 stukken:

  1. [Wayback/Archive] Jeroen Wiert Pluimers: “@ionica ik ga het je proberen uit te leggen. En dan kan jij het vast in veel simpeler bewoording weer terug uitleggen zodat anderen het ook begrijpen. …” – Mastodon
  2. [Wayback/Archive] Jeroen Wiert Pluimers: “@ionica hopelijk heb ik je een beetje kunnen helpen met je opmerkingen in…” – Mastodon
  3. ³

Er waren wat zijstapjes naar onder meer hoe je een goede vraag op het internet moet stellen, dus de draad werd lang (:

Hieronder de volledige tekst, aangevuld met wat gearchiveerde links. Maar eerst twee versies van het liedje “Met puntjes” van Joke Bruijs: opnamen van 1986 en 1988:

Get it while it lasts: Led-pixel display (various Action EU stores)

Posted by jpluimers on 2025/12/11

A cool LED display that is programmable through Python (see [Wayback/Archive] Action led paneel – Boekenwuurm’s blog) made me realise how big Action has grown:

About EUR 20 or CHF 24 in the order of the below query:

There is also a square one, but that one does not remember it’s content during a power off/on cycle.

The above blog mentions this library which sees regular updates: [Wayback/Archive] GitHub – lucagoc/pypixelcolor: A Python library to control iPixel Color devices.

PlantUML network diagrams

Posted by jpluimers on 2025/12/11

Despite UML (Unified Modelling Language) not having a specific diagram mode for computer networks, PlantUML does support a computer network diagram mode.

Here are some links that got me going to design a site to site VPN situation that I will document in more detail later on this blog.

Vibe Coding Is Creating Braindead Coders | N’s Blog

Posted by jpluimers on 2025/12/10

The below blog post sparked my thought into finally having words for what bothered me for such a long time using LLM for coding:

When using LLM for coding, you basically unlearn to solve simple problems. That practically also removes your ability to solve the difficult problems that LLM cannot help solving.

Because the day we stop struggling with hard problems is the day we stop being programmers, and become something else entirely.

When you get an error 103 establishing an SFTP

Posted by jpluimers on 2025/12/10

A while ago I got an error 103 using both Beyond Compare. That did not whos the connection log or error reason, but WinSCP did: it mentioned unexpected output during the logon.

I got reminded that I had already solved this error before via [Wayback/Archive] SSH login works but SFTP login doesn’t – Server Fault (thanks [Wayback/Archive] qreon and [Wayback/Archive] Paulus):

How do you disable these thumbnails that pop up near the end of videos!? : r/youtube

Posted by jpluimers on 2025/12/09

Since a few years, YouTube puts annoyingly overlays on top of like the last 5 to 10 seconds of videos often covering valuable content.

Lately – while preparing for concerts – I have watched a lot of score music videos where the end really is very important to me (see the example below), for instance when rehearsing [Wayback/Archive] La Alhambra – Llano – YouTube until the final end.

The solution came from [Wayback/Archive] How do you disable these thumbnails that pop up near the end of videos!? : r/youtube

GL.iNet GL-SFT1200 Secure Wi-Fi Router On The Go – AC1200 Dual-Band Gigabit Wireless Internet Router | IPv6 | USB 2.0 | MU-MIMO | 128MB RAM | Repeater Bridge | Access Point-M Mode: Amazon.de: Computer & Accessories

Posted by jpluimers on 2025/12/09

For my link archive a router I bought a few years back: [Wayback/Archive] GL-SFT1200 Secure Wi-Fi Router On The Go – AC1200 Dual-Band Gigabit Wireless Internet Router | IPv6 | USB 2.0 | MU-MIMO | 128MB RAM | Repeater Bridge | Access Point-M Mode: Amazon.de: Computer & Accessories

  • It is USB-C powered (the power brick delivers 3A at 5V, but in reality it uses far less).
  • Mode and reset buttons are behind the antenna (see picture below).
  • It is specced as AC1200, but that’s just theoretical a number.
  • It came with EU and UK plug.

I needed it because from prior experience, I knew GL.iNEt can support a special Wireless Repeater mode where it still functions as a router (hiding the LAN/WLAN behind NAT)

connection method

Two physical drawbacks likely due to the portable nature:

  1. the plastic RJ45 ports are slightly too wide which means that these keep falling out [Wayback/Archive] Inline® Dust cover, for RJ45 socket, color: green, 100pcs. Pack: Amazon.de: Electronics & Photo
  2. no holes in the base to hang it to a wall

One firmware drawback: it shipped with v3.212 for which I could not find release notes. Luckily the firmware v3.215 I upgraded to had: [Wayback/Archive] Firmware v3.215 is released – Technical Support – GL.iNet.

Links to product and manuals (the paper manual are just two thin sheets, but the on-line documentation is OK; I was surprised WireGuard and Tor were supported!):

I learned there is another way to instantly turn Google Search into using Comic Sans

Posted by jpluimers on 2025/12/08

Recently learned that [Wayback/Archive] geocities – Google Search works just like [Wayback/Archive] comic sans – Google Search (:

Via [Wayback/Archive] if you search up old web hosting site geocities, everything turns into comic sans (you can also search up “comic sans”) : google
