I've only had a chance to skim so far, but this is an absolutely superb survey of an enormous space. It doesn't just list out a bunch of data structures, it actully helps you build a mental model of all the concerns to think abou

All mainstream languages treat backwards compatibility as paramount at this point, it's table stakes at this point. Rust is no exception. I will admit that because the library ecosystem in Rust is younger, you do see things like Clap&

I would narrow it even further: Go competes with Java. Their forte is both programming-in-the-large on the backend. It's much harder to manage a large codebase/application with Python, but it excels at data science and research p

I truly do not mean this in a snarky way - who is projecting that layoffs are projected to drop and hiring is expected to pick up around July/August?

I haven't used GPT4 to help with any borrow checker issues, but just yesterday I figured out how to make my FFI use case work in about 3 minutes after asking. I'd been struggling with it for hours.

Yikes, this is a pretty judgmental post. I spent my time as a kid joining bands and being in plays, but if someone loves building homelabs, what’s wrong with that? To your point about diminishing returns in technical skills vs social skills

Shooting and killing a random 1% of drivers every day would also prevent congestion, and is fair and equal to everyone. There are other considerations though.

I agree it's not a fun situation, but I'm curious what you expect to have happened instead. What would the "competent management" version of the situation look like?

Without commenting on all the complex dynamics of WFH vs the office, I can say that I, personally, enjoy working in the office more. I am an individual contributor software engineer, without millions in equity in anything.

True, I almost said "data science exploration" as a way to avoid this inevitable comment :). Java can't nearly compete with python (right now) for a certain type of data science programming, but you're right that a ton

I don't entirely disagree that treating IO as something special at the linguistic level is a good idea, but I do think that async is a wildly indirect and confusing way to achieve that. Language designers don't add async to make I

It seems like we're on the same page. My point is that your last comment... > in practice async=IO in most code does not need to be true. We will never avoid the complexity of IO, but we can avoid the complexity of async, and virt

Agreed. And there are big answers of course: data science, web front end, embedded, etc. But when you exclude those things, it does leave a huge swath of "generic back end" software where Java has a large if not dominating prese

by pgwhalen 3y ago
It feels like that's coupling some concerns together. Functions that do IO are more likely to fail, yes, but that doesn't have to do with their async-ness or their slowness.

I live in a similar climate, and while I don’t know what constitutes a “substantial distance,” I will commute and run errands in either of those extremes. On those days it’s a little less fun than the other 95% of days, but still feasible.

Never mind the incorrect math, you have a timing problem: you looked at the price this morning after reading the news about it, but the deal was effectively done overnight. Yesterday's closing price for the stock was $10.89.

Your understanding of SAN usage is narrow, and incorrect in the case of my organization. One major benefit that SAN-backed database storage provides us is, when combined with VMs, enables us to spin up another database instance against alre

by pgwhalen 3y ago
True, but it's not as though the 10X expense is for nothing. A SAN enables a lot more than local storage. I didn't mean to suggest that there wasn't a way to achieve lower costs on storage hardware directly, just that in pr

I'm not super in the know about it, but I believe the total cost of SAN storage at my employer (on prem) is ~10X that.
