More than 10 years ago, I needed a MIME decode for Windows as I was developing some software which implemented S/MIME could sign automatically generated emails and verify incoming ones.
I wrote more about the latter part in Some notes on OpenSSL, S/MIME, email, various RFC standards and their relations.
Now finally the post about what I wanted to schedule for posting back then as well: my question looking for a [Wayback/Archive] MIME decoder for Windows – Super User:

I totally agree with the first comment of [Wayback/Archive] Naming Files and Directories the Right Way – YouTube as it holds not just for file management, but for naming anything including software development:

Some notes (mainly links) on the Oracle Cloud Free Tier as at the time of writing it is the only provider with a “free forever” tier.
In the past for FOSS, there was [Wayback/Archive] Fosshost on Twitter: “@d_feldman Check out fosshost.org for an alternative to Oracle Cloud for ARM/AArch64. We are free, open source and you will never get bill shock. Open source projects must apply only.”, but at the end of 2022 they started to wind down their services as per [Wayback/Archive] Fosshost to Sunset Tenant Services
Fosshost to Sunset Tenant Services
At this time, Fosshost is deeply sorry to announce we are no longer able to continue offering our services.
Because of this, we strongly recommend all Fosshost tenants to backup their data immediately, and migrate elsewhere as soon as possible.
Oh before you begin: if you need a reverse DNS record then be sure to request that as soon as your free tier starts: at that time you have USD 300 credits for running paid services which includes the support to request reverse DNS records.
Anyway, many links on the Oracle OCI Cloud Free Tier (especially the ARM deal is great: lots of RAM as compared to the x86 VMs):

A few years back, this question popped up: [Wayback/Archive] Embedding JS into PDF : cybersecurity
The answer is yes, and you can take this far. Virtualisation far. Which is what these repositories – both by [Wayback/Archive] ading2210 · GitHub – did:
Via [Wayback/Archive] Angry Nerds Podcast – YouTube -> [Wayback/Archive] Angrynerds 235 – Automasturbator – YouTube -> 1540 seconds at [Wayback/Archive] Angrynerds 235 – Automasturbator – YouTube – t=5040s
1:24:00 Hadden we Doom in PDF-vorm al eens genoemd? https://github.com/ading2210/doompdf Er is een vervolg, nu gewoon linux draaien in een PDF https://github.com/ading2210/linuxpdf Dus in feite gewoon een PDF-VMetje

[Wayback/Archive] Setting Up a Raspberry PI with a German Mac Keyboard – Seaside Testing.
Reminder to self: figure out where parameters for /etc/default/keyboard are documented in case I want to use USB keyboards:

In the past, I used to modify /etc/sysconfig/named and add entries to the NAMED_CONF_INCLUDE_FILES setting, then run /usr/share/bind/createNamedConfInclude
to generate /etc/named.conf.include.
As of OpenSuSE 15.4, /usr/share/bind/createNamedConfInclude has become an empty file and NAMED_CONF_INCLUDE_FILES got removed and NAMED_INITIALIZE_SCRIPTS introduced.
So now I changed my playbooks to manually generate /etc/named.conf.include and include it form /etc/sysconfig/named.
Since I hardly perform these new installations, it took a few years for me to find out about this change. Upgrading existing systems somehow kept the generated file and included it.
Related links with quotes as it was hard to find out what changed and how to work around and I wasn’t the only one bump into issues:

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!
