I forgot scheduling this post, but it is still very relevant: about the debugging related materials by b0rk (Julia Evans) as they are not limited to just “The Pocket Guide to Debugging”.
It is excellent material to learn at home, work or be used during education.
Before the Elmo* takeover, she mainly used Twitter to post beta material and later the final versions. Easiest queries to find back the Tweets are:
Here are some of links found via the above lists of tweets:

Given Excel is the most popular functional language (see the video under my post “Everybody should have an obsession with Lisp-like language at least once in their life” @KevlinHenney), this post is on sorting with Excel functions.
I had an array in Excel starting at row 2 (to exclude the headings) where I had to sort on 3 different columns: C, A, B (or numerically 3, 1, 2) so [Wayback/Archive] sorting – How to multi level sort an array in excel, using formulas? I am aware about the way, using SORT button on DATA tab – Stack Overflow (thanks [Wayback/Archive] Armaan Gohil and [Wayback/Archive] Jos Woolley) didn’t fully apply but did put me on the right track as I wasn’t aware that the SORT function allows to specify multiple columns using an embedded array argument.

I thought I had been living under a stone for decades when I bumped into vx-underground (@vxunderground) / Twitter
The largest collection of malware source code, samples, and papers on the internet.
Password: infected
That appeared to be untrue as vx-underground, ran by a team of volunteers, started in 2019 ([Archive] web.archive.org/web//vx-underground.org) right when a few crisis in my life came together at the same time.
So here are the links for my archive as they are great content for both Red Teams and Blue Teams on many things cyber security related:

With World Suicide Prevention Day coming up in less than a week, this is a reminder on how to report on this. Not just important to the media at large, but everyone on social media too.
When you are in The Netherlands:
- Is your life in immediate danger? Call 112 immediately.
- If your life is not in immediate danger but you could still use help, call 113 (standard rate) or 0800-0113 (free of charge) or start an online chat.
When you are outside The Netherlands, find help via these links:
Please read the 1 page large font and visually clear [Wayback/Archive] responsible-reporting-on-suicide.pdf.
The [Wayback/Archive] World Suicide Prevention Day 2024 started with the 2024-2026 triennial theme “Changing the Narrative on Suicide”, so please please please read the above PDF.
If you cannot view PDF on your computer, you can read it through the picture below, or an on-line PDF viewer in your web-browser through these links:

Note that http://neverssl.com is the way to figure out if you are in a captive portal, see below.
In Windows 10, the name of the endpoint changed from msftncsi to msftconnecttest, presumably to make the purpose of the access more obvious in security and audit logs. Nobody will understand that NCSI stands for Network Connectivity Status Indicator.

It refers to a few other interesting sites, for instance about modifying if/how NCSI detects internet connectivity:
