Since I keep forgetting which DBMS uses which method to select just a plain value without a table. I always remember it as my search phrase [Wayback/Archive] SELECT from DUAL, but actually better titled like the question below:

Always learning, I put this book on my wish list for reading: [Wayback/Archive] Effective Software Testing as from what I read it is a pragmatic book aimed at developers and suitable for teaching. That sounds right the niche I am in.
From [Wayback/Archive] Using the book in classroom:

Since this question keeps popping up around me every now and then, despite JSON being around for like 25 years now, this statement from the original designer Douglas Crockford:
[Wayback/Archive] Douglas Crockford – Google+ – Comments in JSON …
I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability. I know that the lack of comments makes some people sad, but it shouldn’t.
Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
Yup, Google+ has been dead for more than 6 years now, so it is important to quote these insights for posterity to find them back.

I got warned about low disk space on drive C: caused by PowerToys taking 7 gigabytes of stale upgrades: [Wayback/Archive] 396918165-154de37a-432d-4cab-84ee-0f5a54eb6575.png (1370×789).
PowerToys itself does not like this situation either: an update will quit without indicating why.
According to their issue tracker, this should have been fixed in v0.58.0* , but it wasn’t, see [Wayback/Archive] Update installed, but installation files not deleted. · Issue #13296 · microsoft/PowerToys · GitHub
So if you disk runs full, check out for a bunch of powertoyssetup-*.exe (why don’t they use Pascal casing for readability here?) files.
If you get chat notifications, then they will likely overwhelm the PowerToys notification that an update is available as Windows by default only can show the most recent 20 notifications, and it is hard to modify that default:

From a while back: [Wayback/Archive] Undergraduate Upends a 40-Year-Old Data Science Conjecture : programming which has a “TL;DR for non CS people” and a “Here’s an explanation” well worth reading.
It’s about the work of Andrew Krapivin with co-authors Martín Farach-Colton and William Kuszmaul.
A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.
Reminder to self to find any real world implementations of this new hashing algorithm.
