Learned a while ago: if you have the username from a GitHub or GitLab user, you can download interesting that sometimes can make life easier (but not necessarily more secure):
github.com/username.keys gives you their public SSH keysgitlab.com/username.keys gives you their public SSH keysgithub.com/username.png gives you their profile image
And that there are tools like gh, glab and age that can make direct use of them.
I love Twitter, so thanks for these for teaching me these little tricks:

Steps for installing Chocolatey on Windows 11 and up or 10 version 1803 and up.
Since I often install Windows on machines where it is not easy to copy/paste longer install commands my steps are slightly different than the ones on [Wayback/Archive] Chocolatey Software | Installing Chocolatey:
- Start a regular command prompt
- Either these two (the options are equivalent, see [Wayback/Archive] curl: transfer a URL | curl Commands | Man Pages | ManKier for
--remote-name and -O):
curl --remote-name https://community.chocolatey.org/install.ps1curl -O https://community.chocolatey.org/install.ps1
Note the cURL pre-installed on Windows 10 since at least 6 years*: release 1803 or insider build 17063 is good enough to download the Chocolatey install script
- Inspect the downloaded
install.ps1 to check if you spot anything you dislike
- Start an elevated (administrator) command prompt
- Start PowerShell
- Execute this command
Set-ExecutionPolicy Bypass -Scope Process -Force
- Execute this command in the folder where you downloaded
install.ps1
- Yup, a custom build of cURL has been pre-installed on Windows 10 and up since more than 6 years:

Every now and then I want to check how a URL redirect, for instance when checking out why a domain failed loading in browsers a while ago because of certificate problems:
The thing was that back then, the site officially did not have a security certificate, but somehow the provider had installed a self-signed one. Most web-browsers then auto-redirect from http to https. Luckily the archival sites can archive without redirecting:
When querying [Wayback/Archive] redirect check – Google Search, you get quite some results. These are the ones I use most in descending order of preference and why they are at that position:

Two sites that can help you out getting weather info on the console:
wttr.in
wttr.in is developed by [Wayback/Archive] Igor Chubin (@igor_chubin) / X and looks at the request header to figure out what kind of output it sends.
It supports various output formats, so on my TODO list is to see how they do their mapping: always an opportunity to learn (it’s based on Python and Go so I am curious what libraries they use as well).
From the documentation:
wttr.in currently supports five output formats:
- ANSI for the terminal;
- Plain-text for the terminal and scripts;
- HTML for the browser;
- PNG for the graphical viewers;
- JSON for scripts and APIs;
- Prometheus metrics for scripts and APIs.
The ANSI and HTML formats are selected based on the User-Agent string.
There are more parameters in the documentation on the main page of the repository and through this command:
curl wttr.in/:help
The idea is derived from [Wayback/Archive] GitHub – schachmat/wego: weather app for the terminal.
Oh: Igor has more repositories at [Wayback/Archive] chubin (Igor Chubin) · GitHub (including [Wayback/Archive] GitHub – chubin/cheat.sh: the only cheat sheet you need which is hosted at [Wayback/Archive] cheat.sh; I thought I had blogged about that before, but found it only in a draft note mentioning that I got it via [WaybackSave/Archive] Nicolas Krassas on X: “The only cheat sheet you need cheat.sh“)
7timer
A 7 timer JSON usage example is at [Wayback/Archive] Get Weather from 7Timer! · GitHub
It has documentation at
Output formats can be chosen from HTML, PNG, XML and JSON.

Interesting: [Wayback/Archive] ufrisk/MemProcFS: The Memory Process File System
MemProcFS is an easy and convenient way of viewing physical memory as files in a virtual file system.
Easy trivial point and click memory analysis without the need for complicated commandline arguments! Access memory content and artifacts via files in a mounted virtual file system or via a feature rich application library to include in your own projects!
Analyze memory dump files, live memory via DumpIt or WinPMEM, live memory in read-write mode from virtual machines or from [Wayback/Archive] PCILeech [Wayback/Archive] FPGA hardware devices!
It’s even possible to connect to a remote LeechAgent memory acquisition agent over a secured connection – allowing for remote live memory incident response – even over higher latency low band-width connections! Peek into Virtual Machines with [Wayback/Archive] LiveCloudKd or [Wayback/Archive] VMWare!
Use your favorite tools to analyze memory – use your favorite hex editors, your python and powershell scripts, WinDbg or your favorite disassemblers and debuggers – all will work trivally with MemProcFS by just reading and writing files!
On Windows, there is even the cool tool [Wayback/Archive] evild3ad/MemProcFS-Analyzer: MemProcFS-Analyzer – Automated Forensic Analysis of Windows Memory Dumps for DFIR:

For my link archive: [Wayback/Archive] How to send raw network packets in Python with tun/tap
I never really played around with tun and tap, so this is a nice opportunity to do so. I know they were the base for VPN on Linux, but just now I learned TUN/TAP are not available on nx, but also on Windows. Cool!

Running Kubernetes containers on Windows means taking into account a different can of worms than running them on Linux.
For example [Wayback/Archive] Fun with Windows Containers – Popping Calc explains about the various isolation levels and privileges (through runAsUserName) and this helpful advice:
