From a while back, which I initially missed because it was in the midst figuring out my ver increasing bowel problems leading up to all my cancer treatments, but still relevant:
[Wayback/Archive] Immo Landwerth @terrajobst@hachyderm.io on Twitter: “That’s why C# emits .callvirt instructions, even if the method isn’t virtual. That forces a call site null check.”
Except inside [Wayback/Archive] Extension Methods, referring to this will never return null.
Yes you can work around this using things like reflection, but the C# compiler will emit .callvirt for any method call which does an implicit null check by the caller which means you never have to check that in callees.
The above tweet quoted the first message of the [Wayback/Archive] Thread by @MStrehovsky on Thread Reader App on working around this .callvirt protection:

Apart from the 1973 and 1977 editions mentioned in NEN 5152 – Wikipedia it also links to a 2016 edition. After a little digging, it has at least had new editions in these years:

A few years back, a few interesting files turned up that are directly served from the testla.com web-site right in the middle when Musk used their software engineers to asses twitter.com code quality:
Some do not exist (of which some any more):

Will need this: [Wayback/Archive] Centurion Deuren: Gebruikers- & Installatiehandleiding KS-Serie (70 – 100) [Wayback PDF View/PDF View]
The problem is that a combination of the buttons of the Centurion remote controls failing more frequently plus that the remote control are unable to teach their code to new universtal remote controls that we still had from our previous home which used a Marantec door.
Universal remote controls are supposed to be compatible with both Centurion and Marantec remote controls.
What I want to figure out is if I can initiate one new remote control from the door opening mechanism, then have that teach other new remote controls.
Hopefully this is the right manual for the model we have (the model number is not visible from below, so need to verify that from a location difficult to look from above).
Fingers crossed.

If I ever want to build a PC again, this site helps me assemble the parts and check their compatibility: [Wayback/Archive] Pick parts. Build your PC. Compare and share. – PCPartPicker
Of course it is not a 100% coverage or guarantee, but it will you a lot of hints when on-line configuring a system.

I need to service a [Wayback/Archive] Technics SL-DD 33 | hifi-wiki.com turntable which I acquired, so here are some links, from hopefully most important to least important, as there were various problems with it (lowering the tone arm didn’t work well and there was some wow/flutter):

I thought I had long gone blogged about the .URL file extension as it has been in Windows for some 25 years now to point to URLs, but I didn’t.
So here are two links on them:

One reason I still use Twitter is that it trumps keyboard shortcuts over other social media I use.

Many web-sites and password managers have a strength indicator built-in.
This is a really good example (with open source JavaScript code!) of one: [Wayback/Archive] zxcvbn: Low-Budget Password Strength Estimation | USENIX
Be aware though that it stores a plain text file named passwords.txt on your system (this seems to confuse some users, especially when their password is in it).
Homans password behaviour does not change much over time, so this half hour 2016 presentation on it is still current: [Wayback/Archive] USENIX Security ’16 – zxcvbn: Low-Budget Password Strength Estimation – YouTube for which you can download:
