Plus, if you look at OpenWebUI horror of a commit history, they don't often take external contributions.

Some global services have control plane located only in `us-east-1`, without which they become read-only at best, or even fail outright. https://docs.aws.amazon.com/whitepapers/lat…

For paper documents, you'd make at least a few copies for storage at the source, and then every receiver will get his/her own notarized copies. Electronically, everyone just receiv…

Start training them from a very young age: competitive coders typical start in secondary/high school or even earlier. Russia has specialized schools to support this kind of educati…

Big claims with not a single benchmark to back them up

Well, only a lunatic would use ZIP with anything but DEFLATE/DEFLATE64

I use ZSTD a ton in my programming work where efficiency matters. But for sharing files with other people, ZIP is still king. Even 7z or RAR is niche. Everyone can open a ZIP file,…

I hate ticket-driven development, but clearing ticket is one way to stay sane when the final objective looks crazily out-of-touch.

Yeah, and all the popular web frameworks include authn and authz as a core component.

OpenWRT stopped doing this 10 years ago, as it was too much hassle to pick a drink that satisfy everyone.

I still remember the day when I used jemalloc debug features to triage and resolve some nasty memory bloat issues in our code that use RockDB. Good times.

The difference is the quality of the OSS implementation: most OSS ASN.1 tool choke on the enormous 3GPP specs and others used in the telco industry, thus cannot generate 100% valid…

DER is still easy, UPER (unaligned packed encoding rules) is so much harder, yet it's prevalent in Telecom industry. Last I checked, there was no freely available tool than can han…

It's not about the VCS, it's about API compatibility being broken. If your code is out-of-tree, every time someone changes an API that break your build, it's your responsibility to…

The use-case is because it's so cheap, why bother with anything less. Currently, I can get 1Gbps Internet for $15, while the cheapest package is 200Mbps for $5. I expect they'll of…

One reason for Spotify's move away from p2p was it was absolutely a no-go on mobile platform, which was rapidly becoming dominant at the time.

I prefer Log4J2 built-in JSON Template Layout to Logback's various JSON output solution. The API of Log4J2 and SLF4J v2 are similar enough that it does not matter for basic usage, …

Not a good example, as the de-facto logging interface for Java was SLF4J. Though I myself prefer Log4J2, as I'm already using Log4J2 as the concrete logging implementation.

We use the same setup, though we use PGBouncer so after switching primary we just force reconnect all clients from PGBouncer instead. The clients will have to retry on-going transa…

I'd be more similar to Debezium-server that runs everything in the same process, than regular KafkaConnect-based Debezium. However, this only does postgres-postgres, so it's a lot …

Ok, so PGLite is used in the Firebase Data Connect's emulator: a test utility, not even the client library. It's a bit disingenuous to lump it in the same sentence and try to misle…

Yeah, I'm gonna need a citation on Google's usage of ElectricSQL, considering that the link points to Firebase Data Connect.

The problem with handcrafted build system is only the author can effectively maintain it. When he moves on, someone has to spend the time ripping it out and replace with something …

Yes, basically any build system that supports distributed caching use digest instead of timestamp when checking modification: Bazel, Pants, Buck, etc. They're all hugely complex th…

Yeah, I think the HFT guys use CPU pinning a lot: 1 process - 1 CPU, so you'd need multiple processes to take advantage of multicores server.
