Sometimes you need to see a tiny bit of code to have this “aha moment”. One for me was a few years back:
[Wayback/Archive] Florian Haas on Twitter: “alias kubectl="TZ=Etc/UTC kubectl" You’re welcome.”

Pricing | Better Uptime
Posted by jpluimers on 2024/12/06
Reminder to show how well my experimentation with [Wayback/Archive] Better Uptime went and how they compare to [Wayback/Archive] UptimeRobot.
For now I am at this plan in [Wayback/Archive] Pricing | Better Uptime:
Free:
- e-mail alerts
- 3-minute checks
- 10 monitors
This suffices to keep an eye on the modest IT infrastructure at both our home and the one from my mentally retarded brother.
Note that other prices on that pages are per month. Despite the default selection being “annual plan” the very light grey and thin “/mo” on a black ground indicates they are still per month, but you get 20% discount with the annual plans).

Is it Pokémon or Big Data?
Posted by jpluimers on 2024/12/03
Fron a while ago but still relevant [Wayback/Archive] Is it Pokémon or Big Data?.
It is a cool experiment to test your own knowledge or for fun to assess recruiters or candidates (;
And it is open source too:

The Twelve-Factor App
Posted by jpluimers on 2024/11/21
Still relevant: [Wayback/Archive] The Twelve-Factor App and [Wayback/Archive] 12 Fractured Apps — Medium
Once Docker hit the scene the benefits of the 12 Factor App (12FA) really started to shine. For example, 12FA recommends that logging should be done to stdout and be treated as an event stream. Ever run the docker logs command? That’s 12FA in action!
Via
- [Wayback/Archive] David Fowler on Twitter: “Is
12factor.netstill the thing or is there a new thing?” - [Wayback/Archive] Kelsey Hightower on Twitter: “12 Fractured Apps“Many of the applications that are being packaged for Docker are broken in subtle ways. So subtle people would not call them broken, it’s more like a hairline fracture — it works but hurts like hell when you use them.””

2014 memory: TL;DR Thank you! You’re awesome! Let’s do it again! • GDG DevFest Netherlands
Posted by jpluimers on 2024/11/08
10 years ago, I decided to step out of my comfort zone and attend the [Wayback/Archive] GDG DevFest Netherlands 2014.
Until then, on the mobile front, I only had deep experience with the .NET Compact Framework, on the cloud framework I had no real experience: my experience were (sometimes huge) systems running in private data centers communicating with various protocols over SNA and TCP/IP (and way before that: UUCP and dial-up) and on the programming front my strengths were .NET and Delphi (with truckloads of scripting) and no experience in Go or Dart (Rust was invented a year later).
So I was really happy with the [Wayback/Archive] TL;DR Thank you! You’re awesome! Let’s do it again! • GDG DevFest Netherlands
I think this comment by Jeroen Wiert Pluimers on a G+ post is one of the best complements we’ve got:“Thanks for organizing this. It was a great conference! A great mix of things outside my comfort zone and things I could relate to from a very different perspective: wonderful and inspiring.”
G+ plus is gone, but this memory will last forever as this was a start widening my horizon learning about GDG like I knew about SDN*, Borland/Inprise/Codegear/Embarcadero DevRel and Microsoft DevRel.

Block 185.235.84.0/22 (which ad broker criteo – used by WetterOnline/WeerOnline/others port-scans) via Sven222@Friendica Social Network
Posted by jpluimers on 2024/10/31
[Wayback/Archive] Friendica Social Network | Sven222 @ Friendica Social Network:
Also, falls jemand UFW am laufen hat und keinen Bock auf criteo hat:
edited: UFW Regel nach Hinweis aus Kommentaren angepasst.
ufw deny out from any to 185.235.84.0/22
Or [Wayback/Archive] Tobias Klausmann: “@sven222 Bei mir ist nftables …” – mas.to:
@sven222 Bei mir ist nftables statt ufw, ich hab dann das hier gemacht:
ip daddr 185.235.84.0/22 tcp dport 443 jump rd
ip daddr 185.235.84.0/22 tcp dport 80 jump rd“
rd” it eine chain, die normal rejectet (also wie “port ist zu” aussieht), aber bei hohen Paketraten zu “drop” wechselt.
Oh, and WetterOnline were the ones that forced the German state weather agency to limit the usability of their free app: [Wayback/Archive] BGH-Urteil: Staatlicher Wetterdienst muss Gratis-App beschränken | heise online.
For that reason alone, WetterOnline and their obvious local brands are blocked here, as is criteo.

scaling != high availability (you more often need the latter than the former); microservices != modularisation (you hardly need the former; you *need* the latter)

I’m not the only one storing tech gadgets in flight cases (:
Posted by jpluimers on 2024/09/05
It was about 2 years ago that Jilles reminded me I had a flight case with gadgets too.
Back when I assembled it in 2018, I had big plans for showing private “cloud” container experimentation and gadget stuff at conferences. Then 2019 kicked in with rectum cancer.
So it was good that he helped me motivating to get it working again, especially as the time around assembling it so much fun and working on it brought back those days.
Here are the pictures:

Some lessons to learn from the CrowdStrike debacle
Posted by jpluimers on 2024/08/20
About a month from International CrowdStruck Day, just a few thoughts, more likely to follow:
- How well does your infrastructure behave when none of your Windows machines can boot?
- How well is your out-of-band management?
- How well is your CMDB doing key management, for instance for BitLocker encryption?
- Is checkbox compliance more important than a single point of failure?
- Can you ensure all updates from your supply chain are staggered/staged/phased with a kill switch when things get out of hand?
- Are the worst case scenarios in your disaster recovery plans really the worst?
- Do you understand the human factor of large scale outages (both of the people that – often indirectly – triggered them – hello #HupOps – and the ones that cannot work because of them)?
- Do you value your people – especially the ones that pulled you out of this situation – enough, and did you rename your Human Resource department into something that is more friendly to your people?
- Do you realise this could have happened on any of the platforms you use, including Linux and MacOS?
- If you were mentioned in the media by not recovering well, do you have any idea how much a target you will be from adversaries?
- Did CrowdStrike finally show some real postmortem instead of the half-hearted communications they did mostly after the weekend following the debacle?
- How does your organisation perform dates of critical files?
- Would other platforms be less or more risky? If so: why?
- Will eBPF solve most of this, or at least centralise the issues and what consequences would that have?

Figuring out what domains/IPs to whitelist for installing/updating winget sources and packages
Posted by jpluimers on 2024/07/25
A few years ago I asked for some help figuring out what to whitelist so that winget can update its sources and install packages.
This is how I found out.
The queste started with [Wayback/Archive] Need help trying to figure out what domains/IPs to whitelist for installing packages · Discussion #2304 · microsoft/winget-cli
