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:

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?

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.

For my link archive: [Wayback/Archive] s3-ocr: Extract text from PDF files stored in an S3 bucket
One reason is archival of books. Even (or maybe especially) in IT, books already have historic meaning especially in narrower fields where they often are not available in the Internet Archive or have been scanned by Google Books.

For my link archive (Swiss pCloud is GDPR conformant, has European servers in Luxembourg, supports Windows/MacOS/Linux/Android/iOS and various browser extensions).
Before the lists of links: note that cloud storage is not a back-up (despite many of them trying to lure you into thinking they are), so note two things:
- Backup stuff in multiple places.
- A backup is only a backup if you can prove that a restore from backup functions well.
The links:

I will need this one day as keeping resources up for sandbox or test accounts can cost a lot when things do not happen according to plan:
Both have been written in golang.
Warning: these can be abused, wreak havoc when accidentally used in production, or not even delete all (it’s software; there might be bugs).

Still working on handling open Chrome tabs after having moved in the period that GitLab had quite a few issues causing my PagerDuty alerts to go wild.
Today PagerDuty gave me 7 calls in 4 hours again (see [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “@gitlab Since 20240312T1727Z I get PagerDuty alerts from HetrixTools for some pages hosted on GitLab. It would be nice if someone could have a look at gitlab.com/gitlab-com/gl-infra/production/-/issues/17717“).
In adddition I need to check if anything made it to the GitLab issue list from the 20230827 connectivity issues I mentioned at [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “Is it @gitlab hosting having transcontinental issues, or are other continental connections affected as well? These are from two different *.gitlab.io pages as measured via @HetrixTools . No issues are listed at status.gitlab.com“.
Back then, this was the most important one: [Wayback/Archive] GitLab System Status: GitLab.com availability issues – October 30, 2023 15:39 UTC
Likely because of this, wiert.me.gitlab.io had been down for a while as well on 20231031 (see [Wayback/Archive] wiert.me.gitlab.io (Recent History) – HetrixTools down from 2023-10-30T15:24Z until 2023-10-30T16:14Z for 3 + 3 + 11 + 27 = 44 minutes.)
Back then, the hardest part was to quickly find out if there was indeed an issue being investigated at all.
The GitLab status multi-media account on Twitter just points to the status page, which makes it hard to find the underlying issue.
I didn’t archive that one in time, but when I got the alerts it didn’t show anything and when it was resolved it was already beyond the cut-off timestamp to mark it as “same day” and the graph didn’t show much down-time [Wayback/Archive] GitLab System Status graph didn’t show much down-time:
