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)… “

Moving an existing GitLab project into a new subgroup is called “Transferring”

Posted by jpluimers on 2022/06/14

Via [Wayback] git – Moving an existing GitLab project into a new subgroup – Stack Overflow

Turns out the “slug” for a project… the part of the URL after the GitLab server domain name is made up of the “namespace” and the project name. The name space is the group/subgroup path, so I was looking to transfer project to new namespace.

Transferring the project to a different namespace means re-typing the project name during the transfer. You can do this using copy & paste.

The documentation is under [Wayback] Project settings: Transferring an existing project into another namespace | GitLab.

Some notes on (temporarily) using CIFS/SMBv1 with Windows 10

Posted by jpluimers on 2022/06/13

Warning: only do this in a well confined network because of the SMBv1 has serious security implications!

Temporarily allowing SMBv1 makes it easier to transfer files from/to ancient Windows XP (virtual) machines.

Sometimes you need those to support hardware for which more modern drivers or support do not exist.

LUMC folders over rectoscopie, coloscopie en diepe verdoving

Posted by jpluimers on 2022/06/10

Ik heb niet alleen prikangst, maar ook onderzoek in ziekenhuizen vind ik eng, dus voorbereiding hierop is voor is belangrijk, want uiteraard ga ik wel (en ben ik de rest van de dag uitgeteld vanwege de propofol).

Deze folders van het LUMC hielpen me de afgelopen dagen met voorbereiding:

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.”

Posted by jpluimers on 2022/06/08

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:

foone on Twitter: I google “industrial USB-C” and now everything is back to shit…

Sciuridae Hero on Twitter: “How are the X-PhishMe and X-PhishMeTracking headers not part of every mail filtering program out there?! Security Industry Idiocy.”

Posted by jpluimers on 2022/06/03

[Archive.is] Sciuridae Hero on Twitter: “How are the X-PhishMe and X-PhishMeTracking headers not part of every mail filtering program out there?! Security Industry Idiocy.”

Kristian Köhntopp made me aware of these headers in [Archive.is] Kristian Köhntopp on Twitter: “Nach einer IRC Helpdesk Session: Macht Deine Firma sinnlose “Phishing Trainings”, in denen sie Mitarbeitern Fake-Nachrichten sendet um zu sehen, wer da was anklickt? Weil diese Firmen ihre Existenz rechtfertigen müssen, sind alle diese Nachrichten per X-Header trackbar.”.

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:
