1984 RULES OF NETNEWS DEBATING at We are ALL Rich Rosen…

Posted by jpluimers on 2026/08/06

A while ago, I got reminded of the [Source:/Archive] 1984 RULES OF NETNEWS DEBATING at We are ALL Rich Rosen… that was posted in Newsgroups: net.flame, net.jokes (which had many ROT13 jokes) back more than 40 years ago by the (in)famous – depending on your point of view – Rich Rosen on his site [Wayback/Archive] neurozen.com – Rich Rosen’s web site (which is in a subfolder, I think because of humour, see [Wayback/Archive] Apache Tomcat/7.0.62 – Error report – this Apache Tomcat version 7 is has been end-of-life since the end of March 2021 :).

I regard is as both fun and insightful, fun for instance as all rules are rated “RULE #1”, and insightful for instance as this is a great quote for on a T-shirt:

UNIX V4 tape successfully recovered

Posted by jpluimers on 2026/08/04

I forgot to schedule this post, but it was great news: a 50+ year old Unix V4 tape that was discovered in November 25 and digitally restored in December 25.

This was a big step forward in restoring the History of Unix.

There was a lot of coverage, but I think this thread was was the coolest part. It starts at [Wayback/Archive] Rob Ricci: “While cleaning a storage room,…” – discuss.systems.

An archive of the tape is now at for instance UNIX V4 tape from University of Utah (raw) : Computer History Museum : Free Download, Borrow, and Streaming : Internet Archive.

Not just the tape was found back, also the 1974 letter accompanying it: Letter to Martin Newell on UNIX delivery to University of Utah : Ken Thompson : Free Download, Borrow, and Streaming : Internet Archive.

If you want to play around with it yourself, then try [Wayback/Archive] UNIX v4 (1973) – Vintage Terminals (which I found through the thread I mentioned above).

Two of the many articles that covered the recovery (pun intended):

Since more than 40 years, `c:tmp.txt` is a valid file path on Windows (because of MS-DOS 2.x)

Posted by jpluimers on 2026/07/22

Some are surprised but because of MS-DOS 2.x compatibility:

`c:tmp.txt` is a valid file path on Windows

Since each drive letter remembers the current directory and that memory bit is not thread-local nor process-local, so relying on it is bad practice.

The above is a quote from [Wayback/Archive] Oleksii Holub 🇺🇦 on Twitter: “So I was trying to understand the difference between <code>Path.IsPathRooted(...)</code> and <code>Path.IsPathFullyQualified(...)</code> and learned that apparently <code>c:tmp.txt</code> is a valid file path on Windows 🤯” which has an image without alt-text on a long bit of Microsoft documentation which I will further quote below.

Many people don’t know this, so here is a list of variations on relative paths:

A lot of GitLab pages links and Git pushing a relatively large commit to GitLab: “error: RPC failed; HTTP 502 curl 22 The requested URL returned error: 502”

Posted by jpluimers on 2026/05/27

Got an error when pushing a relatively large commit to GitLab: error: RPC failed; HTTP 502 curl 22 The requested URL returned error: 502

There was no big difference in information between these commands¹:

  1. git push
  2. git push --verbose

I Built a Commodore 64 Laptop That Never Existed (PI + EMULATION) – The Portable 64 Concept Design – YouTube

Posted by jpluimers on 2026/05/06

Cool to see what 3D printing plus a Raspberry Pi emulating a C64 can do [Wayback/Archive] I Built a Commodore 64 Laptop That Never Existed (PI + EMULATION) – The Portable 64 Concept Design – YouTube.

The Portable 64 with an original Commodore 64 joystick

The Portable 64 with an original Commodore 64 joystick

However, published in December 2025 after Commodore had been resurrected from the C= brands, it would have been way cooler if was based on new Commodore 64 Ultimate hardware.

Maybe someone will do such a portable computer based on that hardware, or even better that it becomes available at [Wayback/Archive] Home | Commodore.

Via [Wayback/Archive] Der Kneisner M100 – oder das “once in a lifetime project” | Computermuseum Visselhövede, about an IMSAI 8080 clone, I bumped into the VT220 based Glass TTY VT220 font and found some links of it and it’s modifications which are listed below by category

Screenshot of Pitfall II: Lost Caverns (Apple II, 1984) – MobyGames

[Wayback/A] Screenshot of Pitfall II: Lost Caverns (Apple II, 1984) – MobyGames

Pitfall II: Lost Caverns (Apple II) screenshot:Title screen (this version has been cracked)

Memories of Apple II, ][e and //c.

There was quite a good crack-scene in The Netherlands with a well known name “The Redhead”.

Back then I didn’t know about the BBS systems involved:

  • NEABBBS: 020-717666 (which was ran by Max Keizer and part of FidoNet)
  • NABBS: 03200-28717 (which I could hardly find any other information about, the areacode was part of Lelystad)

Notes for a Bookmarklet that fixes Wayback Machine archivals of Google Search queries

Posted by jpluimers on 2026/04/01

For a while now, after initially displaying archived Google Search results, it changes the Wayback Machine archival URL after displaying.

Examples:

  • https://web.archive.org/web/20230322163526/https://www.google.com/web/20230322163526/https://www.google.com/search?q=excel+last+delimiter
  • https://web.archive.org/web/20230321192712/https://www.google.com/search?q=excel+textafter+textbefore+textsplit+site:https:%2F%2Fsupport.microsoft.com%2Fen-us%2Foffice%2F&google_abuse=GOOGLE_ABUSE_EXEMPTION%3DID%3D3020867903a1f6fa:TM%3D1679426832:C%3D%3E:IP%3D207.241.225.236-:S%3DTSrpWMPwWKoNpiXh-oD21Q%3B+path%3D/%3B+domain%3Dgoogle.com%3B+expires%3DTue,+21-Mar-2023+22:27:12+GMT

I want to write a Bookmarklet that fixes these.

There is not much in the results of

[Wayback/Archive] “GOOGLE_ABUSE_EXEMPTION” “Wayback” – Google Search, but I think this happens when there is a high frequency Google Search archivals from the Wayback Machine.

Moar FidoNet memories

Posted by jpluimers on 2026/03/27

Below is a dump of links about FidoNet links with a few remarks so I won’t forget as it was 25+ years ago that I stopped hosting the FidoNet node that had been on-line for almost 10 years (I was a FidoNet point for a few years before that).

See also my other FidoNet posts.

dasm – macro assembler for 8-bit machines

Posted by jpluimers on 2026/03/04

Finding a reference to DASM while researching yesterday’s post @jpluimers on Twitter: “@b0rk @jilles_com Acids vs bases.”, it felt even more like a trip like memory lane as I had used it in the 1980s on Apple ][ and Apple //e after mainly using EDASM. Lisa and Merlin.

I am glad that it is still alive and kicking with home page at [Wayback/Archive] dasm – macro assembler for 8-bit machines and repository at [Wayback/Archive] dasm-assembler/dasm: Macro assembler with support for several 8-bit microprocessors.

Especially this history section on the home page rang a bell:

  • Matthew Dillon started dasm in 1987-1988.
  • Olaf “Rhialto” Seibert extended dasm in 1995.
  • Andrew “Dr.Boo” Davie maintained dasm in 2003-2008.
  • Peter Fröhlich maintained dasm in 2008-2015.
  • In 2019, the dasm source code and releases were moved to GitHub.
