Very cool! Here’s something similar-ish but using symmetric encryption (i.e. password): https://mprimi.github.io/portable-secret/ https://news.ycombinator.com/item?id=34083366

There are some restrictions. I had the foolish idea of installing a Tesla charger at home to charge my Bolt. I’ve been unable to ever use it. The wall charger works fine with Teslas. My car and adapter charge fine at Tesla superchargers. Bu

My anecdotal evidence confirms this. Friends in my home country are hooked on Telegram meme groups and as a result they’re spreading [Russian propaganda] conspiracy theories at alarming levels. (Russia is really good at weaponizing memes bu

Same thing as what? Parent was asking about deduping encrypted data. Someone said (wrongly) it’s impossible and I shared a popular project that does exactly that.

Indeed. Borg for example is e2e but able to dedupe. My bookmark archive is 10TB but deduped on-disk size is 100GB because most files are the same across backups! https://www.borgbackup.org/

I had a fascinating conversation with someone that has been working on this system for the last 20 or so years. Water treatment is powered by the geyser and in turn the leftover brown water feeds the geyser. Pretty neat (for sewage)!

Ordering gives you ... ordering. And nothing more. Process 1 receives: 3:00 [1] "P1 is leader" 3:01 [2] "P2 is leader" Process 2 receives: 3:00 [1] "P1 is leader" 4:00 [2] "P2 is leader" This is perfe

Rounding up 'usually works' to 'is reliable' is a recipe for building crappy systems. Rounding down 'usually works' to 'it's not perfect and we need to handle edge cases' is how you build dependa

The fatal flaw is calling them "locks". When programmers think of locks, they think of something that can be used to guarantee mutual exclusion. Distributed locks have edge cases where mutual exclusion is violated. Implementatio

There's some serious flaws in your reasoning. TCP guarantees order [as long as the connection is active] but it is far from being 'perfectly reliable'. Example: sender sends, connection drops, sender has no idea whether the r

I'm sorry, I didn't mean to be bashful. I am not familiar with S3 and maybe what you describe is a perfectly safe solution for S3 and certain classes of usage. I could not get past the point where you promulgate the idea that ZK c

Notice I did not mention FLP. Atomic Broadcast (via Paxos or RAFT) does not depend on partial synchrony assumptions to maintain its safety properties. Your internet or intranet networks are definitely asynchronous and assuming delays are bo

"Distributed locks" are at best a contention-reduction mechanism. They cannot be used to implement mutual exclusion that is _guaranteed_ to work. I've seen way too many systems where people assume TCP == perfectly reliable an

Telling people "here's a recipe to do locks" should come with a giant flashing sign that say: "this is not an actual lock (as in in-process locks) -- locks in distributed systems are impossible, this cannot be used as a

Thank you for the link GP! I’m the ‘maintainer’ but I’m hands off and not planning on significant improvements. Discussion on HN was also quite interesting and you may find some ideas: https://news.ycombinator.com/item?id=34

Leader election and distributed locking reduce to the same problem… which is proven to be impossible. It means in some edge case it will fail on you, is your system handling those cases? I didn’t read past this: > Systems like Apache Zoo

Definitely! 1. Many companies are hiring "AI" engineers. My guess is 90% of these jobs are virtue signaling to investors and those positions will go to folks that are good at appearing competent in interviews. Yay! More overpaid i

Great read. Great product. I've been an early user of Antithesis. My background is dependability and formal distributed systems. This thing is magic (or rather, it's indistinguishable from magic ;-)). If they told me I could test
