I'm a little puzzled: Why should you care? The language in which Bun is written isn't part of its API, if you will. You care that you have something that does various javascripty things according to a particular spec of what it&#x

I wonder if this is part of what's clever about pitching their consultancy as slop cleanup -- nobody's likely to engage them to work on a pile of logic that's been evolving over a decade with weird load bearing corner cases.

You seem to be turning this into a discussion of vehicles, but the post you're replying to was purely about batteries. I get it - ICE cars suck. But speaking for myself, I waited until I could get LFP batteries before adding a lot of l

Strongly agreed, and thank you - TIL about the truckee hitch, I've always been using trucker's hitches and now I'm going to go try to reprogram myself. I'd add a butterfly loop to this list for those times you need to ad

Consumers having a preference is not ok? I feel the same way about Android auto. I refuse to be locked into some terrible, never updated or expensive subscription vendor nav unit. I have a phone. I want to be able to use it.

Filippo Valsorda doesn't work for Google. He left there several years ago. He runs an independent "buy contracts with me to support development of open source cryptography software" thing.

I have no horses in this race and lack the expertise to judge, but this is part of a larger fight and djb seems to be on the other side of a lot of good cryptographers: https://mailarchive.ietf.org/arch/msg/tls&#x2

Accepting 100% that it should be in some way deemed unacceptable (socially or legally) to fake what an apartment actually looks like, I did find using an image model really helpful in making design choices for my bathroom remodel. Mostly ab

One of the best queries I've done with an LLM recently was: Create a plan for improving the robustness and resilience of this code, particularly to untrusted inputs. Gemini wouldn't do a security audit. But it came up with a great

Read my comment more carefully if you think I'm describing the study instead of providing more general context for why people might find this particular study interesting.

I'm giving context for why a study of higher intensity cardio -in older people- might be interesting to people, and why it's not just "exercise good"

Mostly because functional strength is useful and keeps you alive. major goals as you age are avoiding falls and being able to continue doing things for yourself. Strength fits that bill pretty well (and it also improves fat free mass). And

No, but past recommendations for older adults (note that the average age in the study was 72 years old) were towards "gentle" or moderate exercise. We're seeing a shift now towards recommending real weight lifting and higher

That's incorrect, I have one on my desk right now. They've stopped selling it now, but I got one a year and a half ago: > Apple M4 Pro chip with 14‑core CPU, 20‑core GPU, 16-core Neural Engine 64GB unified memory 2TB SSD storag

That's not nearly as true when you look at AI training clusters. They're basically supercomputers but without an FP64 focus. (These are the systems to which GP was referring at Google.)

Sorry! Power Usage Effectiveness. It's a measure of the overhead of delivering power to the servers (or motherboards, depending on how you measure it), taken to include all other datacenter power overheads: AC/cooling, UPS losses,

As someone else noted - it's effectively zero compared to the water evaporated in evaporative chillers. But it's still misleading. The major source of water use in datacenters, by _far_, is the water used in power generation. This

You can do a perfectly good, very efficient mini split for USD $5k. Avoids the leaks of window of portable units. And if you're feeling fancy you can get it as a cold climate heat pump. They're great options for retrofitting - can

Speaking as a professor: the filter is really helpful. Having students struggle for two years in a program they're going to fail out of is terrible. I've seen it happen - and I saw more of it happen for the years CMU also stopped

I think you mean it's lognormal, at least if we're discussing native English speakers or comparing those with similar amounts of exposure to the language. (The median English speaker almost certainly knows several thousand words,

The problem for people like that is that they're working in a system that rewards and mandates bad behavior. You want your traffic tickets to stick so you can make quota? Ticket more black and poor people. They won't contest the t

He's not a loser; he's done some really fun work that many people use daily. I've used his range mapping trick in multiple projects/papers. It's elegant. It sounds like he's gotten bad advise about how to marke

I suggested to a masters' student that a problem we were working on would benefit from analyzing it mathematically. He brought an incorrect solution the next time we met, and on a whim, I asked Gemini to do it. Gemini got it right. I s

Ah! Good question: Google's non-open-weights models (Gemini, etc) have almost always outperformed on image recognition tasks compared to any other models. I use a mix of in-house and Gemini for image classification tasks for $startup.

I was excited about this until I fed it one of my local test problems: coin identification. I then spent 10 minutes arguing with it that a photo of a 1998 washington quarter was not, in fact, a Morgan Silver Dollar. I mean, I wish it was. I

But it does, at least to some degree: For the cpu (or brain) you want high density to minimize the latency between components. For the heat sink, you want high surface area, which you can actually do to some degree three-dimensionally, part
