Finding duplicate objects in an S3 bucket I've been spending more time browsing StackOverflow recently and came across a question asking if it was possible to find duplicate objects within an S3 bucket. One way would be to hash the object prior to upload and store the value in a local or remote data store. If that's not possible or too much overhead, I figured I could use S3 Metadata and Athena to solve this, services I've covered on this Read more.
Goodbye ICE 3M! In 1994, Deutsche Bahn (DB) placed an order for 13 ICE 3M trains. These were the international variants of the 50 ICE 3 trains that would enter service in 1998. The "M" in 3M stands for _mehrsystemfähig_ , as the trainsets would be able to operate under different power supplies, initially for Germany and the Netherlands and later in Switzerland, Belgium, and France. To supplement DB's order, the D Read more.
Querying an object's access tier Amazon S3 Intelligent-Tiering moves your data to the most cost-effective S3 storage tier based on the object's access pattern for the price of $0.0025 per 1,000 objects it monitors.

If you opt-in for asynchronous archive tiers, you can Read more.
Service disruption on 25 March 2025 Last month, my homelab experienced an incident that resulted in service disruption for 3 hours and 8 minutes, and because I like to cosplay as a sysadmin in my free time this is a post-incident analysis. The effects of the disruption were mostly external, mainly affecting the main site and ytrss, internal systems remained unaffected. A virtual machine hosted on Linode needed to be moved between p Read more.

TIL YouTube playlists have RSS feeds you can subscribe to, just like channels. For every new video that gets added, a new entry pops up in the RSS feed. I learned this thanks to @martijnvdven, who added a feature to YT-RSS allowing you to retrieve the feed URL of YouTube playlists (among some other backend code improvements)! https://ytrss.pesky.moe Read more.
With the upcoming trial of a partially car-free Nieuwstraat in Weesp, I was surprised to see about half the storefronts with signs protesting the change. The article has some good archived and current images of the street and covers some of the history. https://www.iloveweesp.nl/2025/04/13/de-schoonheid-van-de-autovrije- nieuwstraat/ Read more.
I just saw a self-driving wheelchair stuck with a passenger at a terminal in Schiphol Airport and had to flag an employee to help. There weren't even any handles to push them along. Very dystopian. Read more.
