Inclusie/toegankelijkheid voor het @LUMC_Leiden: een tabel in HTML in plaats van plaatje zonder alt-text – #a11y

Posted by jpluimers on 2022/06/20

Voor inclusie en toegankelijkheid heb ik het plaatje van de tabel met voedingsmiddelen op [Wayback/Archive] Coloscopie | LUMC onderstaand in een HTML versie gegoten dankzij Google Lens die voor mij de tekst via OCR eruit gehaald heeft.

Dit vanwege een ingreep die binnenkort plaatsvindt waarbij een laxeerprotocol met Picoprep bij hoort.

De tabel als plaatje

De tabel is niet leesbaar voor mensen met een visuele beperking, en is afgedrukt bovendien zo klein dat zelfs voor mensen met een normaal zicht dit bijna niet leesbaar is.

Vanuit oogpunt van (verplichte, zie onder) toegankelijkheid en inclusie van mensen met een beperking is dit onwenselijk.

How can you export the Visual Studio Code extension list? (via: Stack Overflow)

Posted by jpluimers on 2022/06/16

Adapted from [Archive.is] How can you export the Visual Studio Code extension list? – Stack Overflow, presuming that code is on the PATH:

  1. From the command-line interface on MacOS, Linux, BSD or on Windows with git installed:
    code --list-extensions | xargs -L 1 echo code --install-extension
  2. From the command-line interface on MacOS, Linux, BSD or on Windows without git installed:
    code --list-extensions | % { "code --install-extension $_" }

    or, as I think, more clearly (see also [WayBack] syntax – What does “%” (percent) do in PowerShell? – Stack Overflow):

    code --list-extensions | foreach { "code --install-extension $_" }

    or even more explanatory:

    code --list-extensions | ForEach-Object { "code --install-extension $_" }
  3. From the command-line interface on Windows as a plain cmd.exe command:
    @for /f %l in ('code --list-extensions') do @echo code --install-extension %l
  4. On Windows as a plain cmd.exe batch file (in a .bat/.cmd script):
    @for /f %%l in ('code --list-extensions') do @echo code --install-extension %%l
  5. The above two on Windows can also be done using PowerShell:
    PowerShell -Command "code --list-extensions | % { """""code --install-extension $_""""" }"

    Note that here too, the % can be expanded into foreach or ForEach-Object for clarity.

All of the above prepend “code --install-extension ” (note the trailing space) before each installed Visual Studio Code extension.

They all give you a list like this which you can execute on any machine having Visual Studio Code installed and its code on the PATH, and a working internet connection:

code --install-extension DavidAnson.vscode-markdownlint
code --install-extension ms-vscode.powershell
code --install-extension yzhang.markdown-all-in-onex

(This is about the minimum install for me to edit markdown documents and do useful things with PowerShell).

Of course you can pipe these to a text-file script to execute them later on.

The double-quote escaping is based on [Wayback/Archive.is] How to escape PowerShell double quotes from a .bat file – Stack Overflow:

you need to escape the " on the command line, inside a double quoted string. From my testing, the only thing that seems to work is quadruple double quotes """" inside the quoted parameter:

powershell.exe -command "echo '""""X""""'"

AI and ML are just as smart as the training data, which for large sets of data usually gives biased or outright results

Posted by jpluimers on 2022/06/15

Kris phrases a thought that has been lingering in my head for decades: [Archive.is] Kristian Köhntopp on Twitter: “”AI” ist nicht intelligent, sondern reproduziert das Trainingsmaterial und die Vorurteile darin. Es handelt sich um automatisierten Aberglauben und Verschwörungsquatsch. Je größer das Netzwerk, um so wirrer.” / Twitter

Basically there are two kinds of AI:

  • a bunch of if/then/else statements
  • a model based engine that is as bad as it’s training data; the larger the set of training data, the worse it gets.

A few of the images in the excellent thread that Kris quoted (more in the [Wayback/archive.is] PDF): [Archive.is] Owain Evans on Twitter: “Paper: New benchmark testing if models like GPT3 are truthful (= avoid generating false answers). We find that models fail and they imitate human misconceptions. Larger models (with more params) do worse! PDF: https://t.co/3zo3PNKrR5 with S.Lin (Oxford) + J.Hilton (OpenAI)… “

How isotopp became the online handle of Kristian Köhntopp

Posted by jpluimers on 2022/06/09

Like me, [Archive.is] Kristian Köhntopp is a nerd.

Unlike me, Kris bumped into character encoding issues for just about all his digital life. That started about the same time as mine, but again unlike me: he was way more involved in the technical aspects of it.

First a series of Tweets:

Chocolatey on Windows 7: “You must provide a value expression on the right-hand side of the ‘-‘ operator.”

One of the places explaining a more and more frequent error on Windows 7 installations is [Wayback/Archive.is] “You must provide a value expression on the right-hand side of the ‘-‘ operator.” · Issue #29 · shiftkey/chocolatey-beyondcompare:

Be careful when using the System.Threading unit in versions earlier than Delphi 11 (it ditches Windows XP compatibility, for a reason)

Posted by jpluimers on 2022/06/07

A while ago, I got reminded of a few occurrences of Delphi apps hanging after a little less than 2 months of being active.

It does not happen that often, as usually Patch Tuesday requires a reboot, but sometimes it doesn’t, or ops forgot to patch the affected machine.

The common thing for these hanging apps was that they all used the System.Threading unit (introduced in Delphi XE7). That unit relied on [Wayback] TThread.GetTickcount (added in Delphi XE3 in the System.Classes unit) which uses a 32-bit unsigned [Archive.is] cardinal value as it relied on the Windows API [Wayback] GetTickCount function which in turn has this remark:

Wake-on-LAN from a Windows machine

Posted by jpluimers on 2022/06/02

Before digging into Wake-on-LAN on Windows machines, I’ll interlude with basically the canonical wakonlan available on many non Windows machines

On Linux and BSD machines, there is the Perl script wakeonlan (steadily at version 0.41) at [Wayback/Archive.is] jpoliv/wakeonlan: Perl script for waking up computers via Wake-On-LAN magic packets (script: [Wayback/Archive.is] wakeonlan/wakeonlan at master · jpoliv/wakeonlan) with this help:

A twitter call to say nice things about technology sparked interesting threads

Posted by jpluimers on 2022/05/27

A while ago [Archive.is] Adam Jacob on Twitter: “Let’s say nice things about technology today. I’ll start. If it wasn’t for @lkanies and @puppetize, there is no way we would have been able to adapt as an industry to the rise of the cloud. Quote tweet me with your own.” sparked some interesting threads.

First posts are below; click on them to see the full threads.
