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.

Vanaf 1 juli kost opheffen oude spaarrekening EUR 75, dus wees er snel bij: Beëindig je oude spaarproduct – ING – Sparen

Posted by jpluimers on 2022/06/20

[Wayback/Archive] Beëindig je oude spaarproduct – ING – Sparen: tot 1 juli kan dit nog zonder EUR 75 aan kosten.

De flow bestaat uit een stap of 30 (als je kiest voor online identificatie via IDIN) en eindigt heel onverwachts niet op, maar op

Windows: require UAC elevation to enter password instead of a simple “Yes” helps preventing USB HID attacks

Posted by jpluimers on 2022/06/17

Of course you should be careful inserting random USB devices. Apart from USB HID attacks, they could perform other attacks like DMA ones.

To help preventing automated UAC elevation, you can make it harder to activate UAC by requiring a password. I think the below registry trick and policy is supported as of Windows 7, but it could be more recent (i.e. Windows 8.1).

The video below shows the trick, but does not document it in text. So here we go [WayBack] Windows doesn’t ask for your password when changing settings – Windows 10 Forums

reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "ConsentPromptBehaviorAdmin" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "ConsentPromptBehaviorUser" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableInstallerDetection" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableLUA" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableSecureUIAPaths" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableUIADesktopToggle" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "FilterAdministratorToken" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "PromptOnSecureDesktop" /t REG_DWORD /d "1" /f

(A more elaborate batch file with lots more hardening is at [WayBack] Win 10 edits · GitHub)

The registry trick is especially useful for Home editions of Windows which do not allow you to run the Security Policy control panel applet secpol.msc.

The first two values explained at [WayBack] How to configure Windows UAC prompt behavior for admins and users – gHacks Tech News:


This key defines the User Account Control behavior for system administrators. The default value is set to prompt but do not require credentials to be entered. Here are all possible values:

  • 0: A value of 0 allows administrators to perform operations that require elevation without consent (meaning prompts) or credentials (meaning authentication).
  • 1: A value of 1 requires the admin to enter username and password when operations require elevated privileges on a secure desktop.
  • 2: The value of 2 displays the UAC prompt that needs to be permitted or denied on a secure desktop. No authentication is required.
  • 3:  A value of 3 prompts for credentials.
  • 4: A value of 4 prompts for consent by displaying the UAC prompt.
  • 5: The default value of 5 prompts for consent for non-Windows binaries.


  • 0: A value of 0 will automatically deny any operation that requires elevated privileges if executed by standard users.
  • 1: The value of 1 will display a prompt to enter the username and password of an administrator to run the operation with elevated privileges on the secure desktop.
  • 3: The default value of 3 prompts for credentials on a secure desktop.

The changes should take effect immediately. You can for instance set the admin behavior to 0 so that no prompts are displayed, and user behavior to 0 as well to prevent them from running operations that require elevated privileges.

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

Posted by jpluimers on 2022/06/16

Adapted from [] 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/] 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: [] 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/] PDF): [] 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: with S.Lin (Oxford) + J.Hilton (OpenAI)… “
