Decades of speculative science fiction, thought experiments, and discourse led to this. It’s gratifying to see that we’ve garnered enough concern, a major AI lab risking this to reign in the potential of runaway AI disasters. Hopefully we s

Is there a point at which library maintainer feedback would meaningfully influence a by-default JVM change? I keep a large production Java codebase and its deployments up-to-date. Short of upstreaming fixes to every major dependency, the on

Agreed- I come from a Java/C++ shop where we tried to tackle this dichotomy with interop but it ended up causing more problems than it solved. A lot of the work that Java has done with modern garbage collectors is impressive, but even

I mostly agree with this, but I've been a big fan of having primitive types in config. Most of the time if I have something I want to configure, it's either one of the following (or a map/list-based structure consisting of):

Yup. We've clearly benefitted- G1 and generational ZGC have large advantages over CMS- but it's a lot of experimentation and trial-and-error to get there, whereas other deprecations/removals are usually easier to resolve.

Nullable is a huge issue in Java, but annotation-based nullability frameworks are both effective and pervasive in the ecosystem (and almost mandatory, IMO). I'm really excited about https://jspecify.dev/ , which is an e

Depends- one of the hardest parts of the 11-20 upgrade for us was that cms gc was removed. If you run a bunch of different microservices with distinct allocation profiles, all with high allocation pressure and performance constraints, and y

There might be a potential market in HFT/trading firms (market makers). They're struggling to recruit right now (industry is doing very well, so high headcount growth) and they're usually pretty small so joining w/ frien

Is this a theoretical difference, or a difference in terms of an actual implementation? I have no knowledge of linear systems algorithms, but as far as I was aware, many w.h.p algorithms resolve to correctness with probability of 1 - (1&#x2

“Of the 18 crossovers I talked to, 16 said yes.“ I’m just as surprised to see the number be this high. I can’t help but wonder if this might be due to survivorship bias: crossovers are, after all, self-selecting. Perhaps not all engineers w

How do you achieve people like this? From my limited experience (college senior joining a hft firm shortly, so I've recently been in several quant finance SWE interview loops), firms seem to vastly downplay the financial aspects of the

Fantastic book, and one that's much needed in the landscape of compiler learning today. Many modern compiler books (such as Torczon & Cooper's "Engineering a Compiler") take the approach of showing low-level, linear

The way I've seen it calculated is this: For regular classes, A: 4.0, B: 3.0, C: 2.0, D: 1.0 (with some variance depending on + or - grades offered). For Honors/AP classes, every grade is essentially bumped up 1.0 point. So yes, a

For probabilistic algorithms, we can look at the worst-case-w.h.p runtime: that is, a randomized quicksort, although technically still having an "absolute" worst case of O(n^2), actually is considered to have a worst case of O(nlo

On a local level, the FCC paved the way for chain-based ownership of local stations in 2003, despite research suggesting it was a bad idea[1]. That being said, the US media is different on a national level- NYT, WashPo and WSJ (investigativ

The CD standard as the "Joe Average" is quickly changing. Anecdotally, as a younger person (recent college grad), people my age don't buy CDs out of necessity nearly as much anymore as they used to. We've gotten to the p

I think the idea is supposed to be that you have some agency when you share your data with a friend. You can choose whether you want to entrust your data to this friend or not, and the onus is on you to properly vet them for transparency an

I would help my neighbor move some furniture for free, and I'd still do it if he offered to pay me $5. I wouldn't accept the money (because it's socially unacceptable to do so), but his offer wouldn't get in the way of m
