Ah ok, that makes sense. Over loopback, you can roundtrip Redis at least as fast as double-digit micros. Intra-DC, your network latency should be somewhere in the triple-digit micros. I'd say if you're not seeing that, something i

I'm sorry, I don't think I understand your question. Are you talking about the KVS? You shard the servers for extra capacity. Several KVS's have built-in clustering if you want to go that route. They're usually incredibl

Rate limiters seem like the poster child for something you'd want to host in an in-memory KVS. Typical access times look more like ~100us, not milliseconds. Even if you have a complicated algorithm, you can still limit it to a single r

You're definitely not in mortal danger as a SWE, but FWIW, I've witnessed (2nd hand) datacenter servers literally catch on fire and entire datacenters go out because a critter got crispified on some power lines. Sometimes "th

Right, I was careful to say "generated javadoc", but that nuance might not have been obvious. The author's point is not about the syntax you use to write documentation, it's about the experience you have consuming it. (A

Do you have specific examples in mind?

The author rants about Java a lot, when they admit they've never even used it. It shows. People view documentation in their IDEs. Generated javadoc is almost not a thing nowadays. I suspect this is the same in similarly statically type

This is such a weird take. Java's been everywhere in prod in the industry for decades from backends running millions of qps to HFT to game clients. IME, the most common GC problems I see are: - incredibly basic settings are wrong,

Huh? The model 3 didn't come out until 2017 and the model Y came out in 2020. That's literally just four years ago - not 2012. I own a 2019 model 3 and will be replacing it with a 2024. In those 5 years, it's accumulated a bu

This seems in direct contrast to reality. The long-range RWD model 3 (360mi of range) is available for $35K (after federal tax credit). That's more bang-for-the-buck than I've seen for any car in my lifetime. I'm not aware of

I don't really get this. "Love the art, not the artist" is pretty much an essentialism for participating in modern human society. Try taking a moment to trace through everything you consume and see how much of it was originat

There's a third case: dealing with folks who just aren't technically savvy enough to figure some things out on there own, no matter how intuitive, well documented, or fully featured your product is. I think I'd rather trouble

I finished a space recently and, when planning for the ceiling fan, ensured we had a wall switch in addition to the remote. It seems penny-wise pound-foolish to do otherwise.

Usually the proposal is to randomize the processing of the queue. So, as long as your trades get in during the window, there's no advantage to getting in any earlier. In theory the window is so small as to not have any impact on liquid

My experience has been that it's rather heuristic based. It's a clear win when you can immediately see far enough in advance to know that it'll also decrease the amount of generated code. You can spot trivial cases where this

At $6343 [1] for 13.5kwh [2], seems closer to $500/kwh? The federal rebate does help substantially, but most folks should qualify. This # is closer to $400/kwh if you buy with solar, and $300 if you're buying a few instead of

Can vouch for this having fixed non-determinism bugs in a compiler. Nobody is happy if your builds aren't reproducible. You'll also suffer crazy performance problems as everything downstream rebuilds randomly and all your build ca

Zachtronics ( https://www.zachtronics.com/ ) is amazing, but their games are lower level programming. You're typically designing hardware or writing assembly. I haven't played them all, but I can vouch for last call

I've watched that video and seen it quoted a fair number of times, but I don't see how it jives with the reality of tax collection and spending - at least in my area of residence (ATL). I'd love some hard data on how the city

At what population does a city qualify to discuss transit policy? Atlanta has over 6M residents. I think mass transit can be great in the right contexts. For ATL, I think it makes the most sense in the few sq miles of city proper, not 20+ m

My experience is the opposite. The harder it becomes to visit a locale, the less likely I become to visit it. Eventually I decide it's not worth visiting at all.

I can second GP. I have always heard and used authz and authn (pronounced auth-z and auth-n). Bare "auth" typically was used to mean both, but IAM was more clear for that in specific contexts. E.G. you might say someone "auth
