Reminder: see if I can implement megabool in Delphi (or at least trilean)

Posted by jpluimers on 2025/05/06

Now that I re-wrote my 2012 talk on Class Operators and Helpers and presented it in Delphi at the ITDevCon2024 ([Wayback/Archive] ITDevCon | Home – Rome, 2024), see [Wayback/Archive] GitHub – jpluimers/ITDevCon2024: Temporary ITDevCon2024 repository until I fixed the «git checkout “Illegal byte sequence”» of my Conferences repository, here is an idea to check out if I can implement it in Delphi:

Trip down memory lane: book on p-Code based UCSD Pascal

Posted by jpluimers on 2025/05/06

Last week I wrote on File scoped namespaces – C# 10.0 draft specifications | Microsoft Learn, promising to write more on p-Code and UCSD Pascal. That’s now (:

I started with [Wayback/Archive] “java byte code” “ucsd” “p-code” – Google Search as I was looking for really old material on this (Java 1.0 versions became available in the 1994-1995 time frame, and a lot of material back then either did not make it to the World Wide Web (which slowly gained popularity around that time, see History of the World Wide Web) or has vanished due to link rot.

The cool thing is that many “new” people are not even aware of p-Code, as the 2019 thread [Wayback/Archive] What do you think about something like Pascal bytecode? shows.

I learned a thing or two from it as well, for instance that there has been a “recent” book on UCSD Pascal:

September 2024 – Agust Tell HN: Twilio quietly removes Authy iOS app from Mac App Store, stops updates | Hacker News

Posted by jpluimers on 2025/05/05

Installing the Authy iOS app on a Apple Silicon Mac (M1/M2/M3/…) used to be the way to keep using Authy in the Mac Desktop, as early this year Authy announced their desktop applications would shut down by August (links further below).

I missed the September 2024 post [Wayback/Archive] Tell HN: Twilio quietly removes Authy iOS app from Mac App Store, stops updates | Hacker News, which basically means that if you had it installed on a Mac, it will keep being installed but never updated.

This was done silently by Authy owner Twilio making new installs are possible, never updating old installs any more thereby effectively decreasing your security.

Anyway: if you want to try side-loading, this is the iOS app link: [Wayback/Archive] Twilio Authy on the App Store.

Sideloadly (links further below)  might work, but in reality it likely is better to have your MFA running on a separate device.

Some posts on example domains and example IP-ranges (IPv4 and IPv6)

Posted by jpluimers on 2025/05/05

Here are some of my blog posts on documenting using example domains and example IP-addresses or IP-ranges:

(I really wish that example.org and others would service SMTP with blackhole routing so one can also use it for bogus email addresses in documentation)

The blog posts above were incomplete (IPv6 was missing; IPv4 was not explained), so below are more links that do a better job based on a Tweet from [Wayback/Archive] Julia Evans (@b0rk).

Exporting Chrome History (with the “new” configuration and state file structure), and Epoch dates on various systems

Posted by jpluimers on 2025/05/02

Quite a while ago, Chrome moved from a structure based on “Current Session“, “Current Tabs“, “Last Session” and “Last Tabs” into “Session_#################” and “Tabs_#################” stored in a “Sessions” folder (and similar migrations for other state and configuration files).

The numbers in the “Session_*” and “Tabs_*” files are time stamps of those sessions, for instance one needs to figure out what the “13310808970819630” in “Session_13310808970819630” and “Session_13310808970819630” means.

Lot’s of web-pages with tips and tricks around the old structures are still around, often surfacing high in Google Search results.

I was interested in a particular trick to export Google Chrome browsing history and had a hard time figuring out the easiest solution.

Monty Python and the Holy Grail turns 50 – Ars Technica

Posted by jpluimers on 2025/05/02

It first I thought “I didn’t know they had birthday on my birthday”, but then found out the article [Wayback/Archive] Monty Python and the Holy Grail turns 50 – Ars Technica got published on my birthday.

In fact Monty Python and the Holy Grail got released on 19730403 in London, and towards the end of April in the USA.

Dutch audio fragment of mid april about the anniversary: [Wayback] mp3 on [Wayback/Archive] Erik van Muiswinkel over 50 jaar Monty Python and the Holy Grail | NPO Radio 1 is great.

GitHub – randomaccess3/googleURLParser: parser for Google search strings

Posted by jpluimers on 2025/05/01

Back when I observed the Google Search sei parameter which I hadn’t seen before yet, I bumped into [Wayback/Archive] GitHub – randomaccess3/googleURLParser: parser for Google search strings

It covers a truckload of parameters, including the sei one, which isn’t as new as I thought, as it was at least 2017 old: [Wayback/Archive] [Neat URL] Yet another Google parameter… · Issue #25 · Smile4ever/firefoxaddons · GitHub

Links referred from the parser tool for further reading:

File scoped namespaces – C# 10.0 draft specifications | Microsoft Learn

Posted by jpluimers on 2025/05/01

Oops, I thought this had been published a long time ago, but oh well: it is never too late to publish reflections on a C# programming language improvement.

After recovering from my rectum cancer treatments and finally upgrading most of my projects to recent enough C# versions, it was time to catch up on useful little C# language features released during my treatments.

This one is really nice: [Wayback/Archive] File scoped namespaces – C# 10.0 draft specifications | Microsoft Learn.

I wish it had been released much earlier, as it so much reminds me of the unit keyword in Delphi which influenced C# a lot. Well, actually the unit actually started in UCSD Pascal and Turbo Pascal; UCSD Pascal ran on the UCSD p-Machine (more on that in a future blog post), which influenced the Java Virtual Machine, which was based on Java bytecode and a Just-in-time compiler in turn influenced the .NET Common Language Runtime.

There are many examples from other languages, paradigms and frameworks: I love how C# and .NET bring so much programming history together.

In Delphi  it is easy: a source file can contain at maximum one unit (and apart from files included in that source file, no other source files can contribute to that unit) and the filename needs to match the unitname, so the unit is a self contained namespace.
