MySQL: Row Literals | Die wunderbare Welt von Isotopp

Posted by jpluimers on 2025/01/07

For my link archive: [Wayback/Archive] MySQL: Row Literals | Die wunderbare Welt von Isotopp

Question on the Libera/#mysql IRC channel:
Is there a way to split a simple select into multiple returned rows? For example, select 1, 2, 3 to be returned as rows?
This is actually asking for a table literal notation. I know of four ways to construct a table literal in MySQL:

They are based on UNION ALL, JSON_TABLE and VALUES statement (the latter in two forms). I knew about the first (which I used in other database environments), not about the others.

Getting the list of vscode extensions when it upgraded to a version not supported on the platform any more (and packing your extensions in a .vsix list package)

Posted by jpluimers on 2025/01/02

While moving from ancient hardware to more modern hardware, somehow Visual Studio Code had updated itself to a version that didn’t support the underlying operating system any more. Bummer!

Normally I would get the list of extensions through this command (which is listed in many places, like in my blog post How can you export the Visual Studio Code extension list? (via: Stack Overflow), but also for instance answered in the below question by [WaybackSave/Archive] Benny Ng):

code --list-extensions

That obviously would not work, but thanks to [Wayback/Archive] How can you export the Visual Studio Code extension list? – Stack Overflow (thanks [Wayback/Archive] Andrew and [Wayback/Archive] MarkP) I now could do this:

ls -alh ~/.vscode/extensions

(That directory obviously is also in various forms of official documentation like in the the Your Extensions Folder section of [Wayback/Archive] Publishing Extensions | Visual Studio Code Extension API.

A comment to the above question pointed me to an interesting way to automate extension installs on various machines: pack the installed extension list into its own .vsix file:

Modifying your receiver/amplifier: Converting Phono Inputs to Line-Level

Posted by jpluimers on 2025/01/02

For my link archive: [Wayback/Archive.is] Converting Phono Inputs to Line-Level

It shows for some receiver models how to have the Phono input signals bypass the preamplifier (preamp) so they effectively become Line level inputs and there is no need for an extra devices that undoes RIAA equalisation.

If that fails, then you need something like the [Wayback/Archive.is] Line level to phono input converter diagram:

Or get you a [Wayback/Archive.is] iRIAA2 – Inverse RIAA Filter – Hagerman Audio Labs

Old programming books had cool little “puns” in their references, modern lack them in their indices. On the why, and history of them.

Posted by jpluimers on 2025/01/01

I wrote a two earlier blog posts around puns in programming book indices before:

  1. the 1992 Turbo Pascal 7.0 Language Guide having both entry in the manual about Recursion (“recursive loop, see recursive loop”) which of course is similar to “infinite loop” and entries for “infinite loop See loop, infinite” and “loop, infinite See infinite loop”.
  2. infinite loop in “LaTeX: A Document Preparation System” by Leslie Lamport, printed in 1994.

In the last one, I promised to list more occurrences which I now finally had time for to do.

But let me first elaborate more on the observation that modern computer books (like for instance on C# and Delphi beyond version 1) lack these kinds of index pun.

On the Delphi side, the index entry joke for recursion got removed no later than Delphi 3 (I am still looking for a Delphi 2 version of the Object Pascal Language Guide, see further below) even before the book being fully redone electronically and the index pages generation being automated in

I think I even understand why that is: the process of creating of indices. By the start of this century, more and more indices were automatically being generated and for the last 2 decades or so, all of them are. Back in the days however, indices were mostly done by hand. Nowadays, with everything automated, it is actually pretty tricky in most environments to add such an “infinite loop” index entry like in the Turbo Pascal book, as it would require two things at once:

Pentium FDIV bug – 25 years ago; Ken Shirriff reverse engineerded the cause under a microsope

Posted by jpluimers on 2024/12/31

A small introduction is the Pentium FDIV bug – Wikipedia article which already has some of the highlights..

Ken Shirriff however went all the way in, and used a microscope to focus in on to the actual cause.

He wrote two Mastodon threads on it watching (most recent first, with a link to his blog post) making a good year’s end read:

A truckload of links which I need for some Bookmarklets work

Posted by jpluimers on 2024/12/31

A while ago, browser tabs were overflowing again so I first mad the list of links with quotes below, then discovered there is a template for many browser tabs open at [Wayback/Archive] To many browser tabs open Meme Generator – Imgflip

One of the reasons is that the WordPress “Press This” bookmarklet is very slow and also flaky at escaping HTML (for instance the below html – Why shouldn’t &amp;apos; be used to escape single quotes? – Stack Overflow sometimes becomes html – Why shouldn’t <code>'</code> be used to escape single quotes? – Stack Overflow in [Wayback/Archive] Press This – WordPress plugin | WordPress.org especially when running it from Archive Today archived pages).

So here we go: Read the rest of this entry »

HInvoke and avoiding PInvoke | drakonia’s blog

Posted by jpluimers on 2024/12/26

On my research list [Wayback/Archive] HInvoke and avoiding PInvoke | drakonia’s blog.

A very minimalistic approach of calling .net runtime functions or accessing properties using only hashes as identifiers. It does not leave any strings or import references since we dynamically resolve the required member from the mscorlib assembly on runtime.

x86 assembly – Difference between JE/JNE and JZ/JNZ – Stack Overflow

Posted by jpluimers on 2024/12/25

This brought back memories of some 40 years ago during my first steps learning x86 assembly language, realising the first comment: [Wayback/Archive] assembly – Difference between JE/JNE and JZ/JNZ – Stack Overflow

Q

In x86 assembly code, are JE and JNE exactly the same as JZ and JNZ?

C

Long answer: yes.

C

TL:DR: same machine operation, different semantic meaning. Just like jb / jc / jnae all testing CF=1. See felixcloutier.com/x86/jcc

Merry X-mas everyone!

And thanks [Wayback/Archive] Daniel Hanrahan for asking, [Wayback/Archive] Hans Passant and [Wayback/Archive] Peter Cordes for commenting.

Be sure to read the rest of the comments and answers to read on the WHY these instructions are the same. That insight made me realise I was finally understanding the x86 architecture at a deeper level.
