When Archive.Today (and their .fo/.is.li/.md/.ph/.vn) look down; check your DNS

Posted by jpluimers on 2025/05/19

The [Wayback] Archive Today blog has not been updated for more than a year now*, and this looks to coincide with up-time issues.

Part of the inability to save pages in Archive.Today (or any of their other domains) or access them can have to do with DNS issues, actually confirmed by the linked Wikipedia article. There are many links on them, some are these reddit threads:

  • Note the problem archiving the Archive Today blog into the Wayback Machine isn’t always successful. When trying around the moments that Archive Today could not archive pages, the Wayback Machine could not find the Archive Today blog in their DNS, see the the picture below.

The really cool thing is that during after the Internet Archive hack (and therefore Wayback Machine downtime), Archive Today held up pretty much OK, so not all is bad (:

Anyway Archive Today archival started to work again after some 4 hours of problems, and I got dragged into other work, so there was no chance to investigate further. Hopefully another day… or preferably: hopefully they stay up.

Some links on the Apple IIc Plus (Apple IIc + on the boot screen) likely the rarest from the Apple II series

Posted by jpluimers on 2025/05/16

A while ago I bumped into this video about likely the rarest model in the Apple II series: the Apple IIc Plus:

[Wayback/Archive] Apple IIc Plus – the rarest and fastest Apple II! – YouTube

Returning to one of my favorite subjects – the Apple II – I decide to finally repair a broken Apple IIc Plus gifted to me a little more than a year ago. This machine was the final true hardware revision to the Apple II line, coming in 1988, and the last standalone machine in the line released. It was also the fastest, with a 4Mhz CPU (vs. 1Mhz in most other Apple II’s, and 2.6Mhz in the IIGS). But it was a problematic machine for Apple, with a concept that had been watered down to the point of, well, pointlessness.

The market wanted it even less than it wanted the original IIc (which was my first computer – the one in the thumbnail is my original machine). Still, it is an interesting computer for its accelerated CPU, and its somewhat anachronistic nature at the time of its launch.

It has a cool demo of Flight Simulator II demo mode (which back in those days crashing the plane – demo modes luckily improved from there :) at both 1 Mhz and 4 Mhz. It indeed is not smooth, but a lot faster.

The problem back in those days with acceleration is it would not just improve render speed, but also increase clock time speed. It made most games almost impossible to play in accelerated mode.

If I ever get one, I need to replace the 110V power supply with a 240V/110V auto-switching one as per [Wayback/Archive] IIc + 240v Power:

The video is on the walled garden called Instagram as well, but since I intentionally don’t have an account there accessing is hard. Anyway, it is at: [WaybackSave/Archive] Instagram: „Cyber Gangsta’s Paradise“ feiert Premiere 🎶🎬.

In the past, picuki was an alternative. Now it fails for instagram content.  [Wayback/Archive] Instagram Reels Download with Reels Downloader got me to [Wayback/Archive] cdninstagram, which in the end worked.

Yes, you can globally block JavaScript and enablpe per-site, but you block Bookmarklets too

Posted by jpluimers on 2025/05/16

Trying to trim down excessive CPU usage of my web browsers, and lessen the risk of intrusion, I experimented with globally disabling JavaScript and only enabling it on sites where it adds value to me.

That is possible (see below), but immediately showed a big side effect: Bookmarklets will not work on sites that have JavaScript disabled.

Disabling JavaScript globally only allows Bookmarklets on sites where you have enabled JavaScript. Not the situation I hoped for (:

I’ll try it for a while though.

My first computer, which I bought way after my first programming contest

Posted by jpluimers on 2025/05/15

1988: my first computer

Earlier this year, I found back the ad on the right of the first computer it bought including monitor: at JWC Computers in The Hague¹ where after the the warranty period was over I found out the 16 Mhz 286 processor was a 12 Mhz configured with zero wait state. Luckily I could exchange the VGA card which wasn’t really compatible with a more compatible one.

The machine really boosted my software career and made me start my own company in august 1989 at age 20.

The start of the career however was about a year after attending this programming contest:

Using the computers at university, I showed off some more Turbo Pascal things I created (including a graphical mouse cursor in text-mode²) right after the CP/M and CP/M-86 support was dropped in favour of DOS at the end of the combined Turbo Pascal CP/M and DOS versions. Hello Turbo Pascal 4 with units³, .EXE support, new IDE and new-style manuals, Turbo Pascal 5.0 with integrated debugger, Turbo Pascal 5.5 with objects, Turbo Pascal 6.0 with Turbo Vision and MDI, and Turbo Pascal version 7.0 with DPMI and Windows support (the last two in Borland Pascal; and Windows support also separately available in the OWL based Turbo Pascal for Windows 1.0 and 1.5) sharing the same DLL and DOS Extender support system, syntax highlighting.

1986: my first and only programming contest

I found back JWC computers a few days after finding back my first ever computer programming contest in 1986 [Wayback/Archive] Jeroen Wiert Pluimers: “@bert_hubert @ionica Jullie …” – Mastodon

Bij Micro Masters Holland in 1986 ging het dus al om de UI en niet om de inhoud (:
In educatieve software bleek toen al nauwelijks brood te verdienen.
Misschien als ik toen @WGAvanDijk gekend had…

Followed by [Wayback/Archive] Jeroen Wiert Pluimers: “@bert_hubert @ionica @WGAvanDi…” – Mastodon

Oh kijk: het andere interview van Nico Baaijens (Paul van der Bijl van het vorige interview teruggevonden op Twitter: @paulvdb)

Wat wist ik toen al veel en weinig tegelijk.

Dat is niet heel veel veranderd (:

That contest was a result of The calculators that got me into programming (via: calculators : Algorithms for the masses – julian m bucknall).

I was quite good at Turbo Pascal programming, which landed my first freelance gigs and led me – after FORTRAN and x86 assembly language side-steps – to Delphi, C# and many scripting languages on many platforms. Of course DOS, Windows and OS/2, but also VAX/VMS, BSD (including MacOS, SunOS and the migration of the latter from BSD to SVR4), HP UX, AS/400, AIX, and of course Linux including embedded varieties of some.

There is remarkably little information about Micro Masters Holland via Google Search, but other searches have more results. From those, my conclusion is that the contest ran at least 3 times. Below some articles grouped by the years it ran.

Did you spot the image behind the lamp. Yup: Karateka – a game I loved and still do. Thanks Jordan Mechner for creating that!

The full article by Nico Baaijens (also interviewing Jos de Klerk who now works at Settels Savenije) from [Wayback/Archive] Algemeen Dagblad » 17 mei 1986 – Art. 227 | Delpher

The insert on the top right is about addiction. Even back then I thought that wording was too strong: it is an addiction when things run out of hand. Looking back, it never really did. The time spent programming was a combination of passion and avoiding my mom. Only much – at age 50 – I found out the cause for that: she had been narcissistic since her youth and kept pushing me beyond my limits to compensate for the shortcomings of my mentally retarded brother. That was the real problem and combined with my autism and skills the reason I ended up in IT: a kind of mental safe space.

A tiny bit of history on them in the replies of a blog post describing a very similar store: [Wayback/Archive] Weans, Den Haag – blafhert

Weans & sunshine zijn een en de zelfde, op een gegeven moment (bijna tegen het einde) kwam er nog een filiaal & kantoor bij in de Pasadena in den haag. Dit was de “groothandel” hier kochten bedrijven zoals DES en King computers (wie kent die nog) hun spullen.

Owja Weans staat idd voor we are not stupid.

Die ene Marc, heeft in een veel later stadium in onze organisatie gewerkt, dat was bij EURO P.C. met vestingen op de segbroeklaan en 2 in de fahranheitstraat,het klopt wel dat ook dit een vestiging was van Sunshine N.V.
Onze holding is begonnen met computerverkoop in 1983 !!!, onder de naam EPC ,JWC computers , Necom en RE-Paco. met 5 vestigingen in den haag en 1 in Rotterdam, spectaculaur was onze vestiging in de weimarstraat te den haag waar een omzet
op zaterdag gerealiseerd werd van 1 MLN, het einde van deze vestiging is geweest een overtreding van BUMA er werden namelijk firenzo DOS bij een systeem geleverd welke uitstluitend geleverd mocht worden bij FIRENZO systemen.

Dat weans geen belasting betaalde is niet juist het bedrijf is ten onder gegaan door het opstarten van een memory fabriek in nederland en zoedoende alleen grondstoffen te hoeven importeren om zodoende de anti dumpheffing te ontlopen, die in die tijd 60% was, wij kregen een navordering van 150 MLN voor in ogen van overheid ontdoken invoerrecht, uit eindelijk heb ik de bete afgekocht voor 32 mln.

Ik blijf de verhalen van Jan hier boven hilarisch vinden. 90% een leugen. Heb er bijna 3 jaar gewerkt tot aan het bezoek van de FIOD. Bleek bij het GAK dat er voor het personeel nooit iets was afgedragen, terwijl wij dachten van wel. Jan was een briljant zakenman, kon iedereen oplichten waar je bij zat, draaide vele BTW carrousels en verdiende zich scheel. Maar ieder woord uit zijn mond was meestal onzin om zijn handel te verkopen.
Toch kijk ik met veel plezier terug op de tijd dat ik daar gewerkt heb.

² It was cool to see a similar solution mentioned at [Wayback/Archive] mouse – Graphics Cursor in Assembly – Stack Overflow.

³ A unit like modules concept was already in the beta version of the never Borland released Turbo Modula-2 later released as

Compiler Explorer does Rust. Rust really is strict: some Tweets that helped me learn how strict.

Posted by jpluimers on 2025/05/15

Just remembered that I had a fall 2021 note lying around about Compiler Explorer having evolved and been doing Rust for quite a while now: [Wayback/Archive] Compiler Explorer: G54Mb9Es3

gcc.godbolt.org
Compiler Explorer - Rust (rustc 1.55.0)
pub fn add(a: u64, b: u16) { println!("{}", a + b);

It shows that integer types [Wayback/Archive] u16 and [Wayback/Archive] u64 cannot be added together without conversion or casting. Which is an example of the strictness that Rust requires. I think that is a good thing,

Via this tweet tree (as opinions on idioms vary so it is good to understand why):

Early Firefox history thread by @asadotzler on Thread Reader App (from before it was called Phoenix, heck from before Phoenix was created!)

Posted by jpluimers on 2025/05/14

A few years back I bumped in this cool [Wayback/Archive] Thread by @asadotzler on Thread Reader App on early Firefox history (from before it was called Phoenix or Firebird, heck from before Phoenix was created!).

It is important to keep telling these bits of history as they are fundamental to understand the Web Browser landscape as it is now.

Great material that complements Wikipedia articles like these:
