The probability of an attack on a UK nuclear facility outside WW3 scenario is almost 0.

If we come to that state of things, then almost anything we do isn't safe.

I recently wrote an explainer for the sqlite file format with some helpful diagrams. This might help.

Immutable append only persistent log doesn't imply store everything _forever_.

If you want to remove something you could add a tombstone record (like Cassandra) and eventually remove the original entry during routine maintenance operations like repacking into a more efficient format, archival into cold storage, TTL handling etc.

A notable example of a large-scale app built with a very similar architecture is ATproto/Bluesky[1].

"ATProto for Distributed Systems Engineers" describes how updates from the users end up in their own small databases (called PDS) and then a replicated log. What we traditionally think of as an API server (called a view server in ATProto) is simply one among the many materializations of this log.

I personally find this model of thinking about dataflow in large-scale apps pretty neat and easy to understand. The parallels are unsurprising since both the Restate blog and ATProto docs link to the same blog post by Martin Kleppmann.

This arch seems to be working really well for Bluesky, as they clearly aced through multiple 10x events very recently.

Pkl was one of the best internal tools at Apple, and it’s so good to see it finally getting open sourced.

My team migrated several kloc k8s configuration to pkl with great success. Internally we used to write alert definitions in pkl and it would generate configuration for 2 different monitoring tools, a pretty static documentation site and link it all together nicely.

Would gladly recommend this to anyone and I’m excited to be able to use this again.

This is what I wanted Apple News to be.

I wish it would give me a good curated news feed from dozens of sources, and adapt based on feedback. I badly wanted to love it, but no matter how much I tried it ended up looking something like a mix of Buzzfeed and Murdoch propaganda.

Happy to see the idea is not dead and new companies are giving it a shot.

Knowing apple, its probably illegal for those 2 teams to talk to each other.

Great post! I find it interesting that all root servers are located in United States. Should some of them be elsewhere for redundancy?

There is a solarized version as well which I've used a few times in the past. https://thomasf.github.io/solarized-css

ASCII is English and limiting access to knowledge for the rest of humanity for a simpler encoding is just not an acceptable option. Someone needs to interpret those 7k words and write a (complicated?) program once so that billions can read in their own language? Sounds like an easy win to me.
