dpe82··on US Vaccine Panel Chair Says Polio and Other Shots Should Be Optional
You created a straw man; the parent specifically wrote "ignorance" which is very different from "dumb" or "cruel".
dpe82··on Significant US farm losses persist, despite federal assistance
It's not just that; being a very small undifferentiated supplier in a volatile commodities market with very high fixed capital costs, unpredictable/uncontrollable production capacity and long production lead times is a very difficult business, regardless of the industry.
dpe82··on From Nevada to Kansas by Glider
Minden is a very popular place for gliders; with the right conditions the Sierras trigger serious mountain wave that you can ride for a long, long way.

Mind helping us all out ahead of time by expanding on what kind of gotchas FUSE is full of?
dpe82··on 90M people. 118 hours of silence. One nation erased from the internet
We haven't had a major conflict in 80 years. Little skirmishes all over the place, sure, but we've forgotten that significant wars between major powers used to be both terrible for everyone involved and also common. Our grandparents after WW2 decided to go a different path and created a largely rules- and trade- based international order that has largely kept the peace. We don't realize how good we've had it.

Now if only there were a Nix-like system for FreeBSD! :)

I've recently begun moving the systems I administer to Claude-written NixOS configs. Nix is great but can be a real pain to write yourself; Claude removes the pain.
dpe82··on How Markdown took over the world
In what ways is it a superset? What can you express in markdown that can't be expressed in HTML?

dpe82··on AI as the Engine of Application State
Ok cool - yeah that's a very reasonable place to start. I've been toying with ideas for "AI driven UIs" but haven't really experimented with much concrete yet. I feel like there's a lot of space to play here though. Eg. let the AI also create controls that are backed by prompts, etc.
dpe82··on “Erdos problem #728 was solved more or less autonomously by AI”
TFA says ChatGPT wrote the informal description.
dpe82··on AI as the Engine of Application State
This seems really interesting though I'm struggling to picture how the AI and UI interact? Is the UI just a reflection of the folders/files on disk that the AI updates? Are there UI interactions (buttons, etc.) that trigger the AI to do something, somehow? More detail would be super helpful!

Whenever I hear libertarian economic theory I always picture my physics professor prefacing every problem with "assume a perfectly uniform sphere..."
dpe82··on We replaced H.264 streaming with JPEG screenshots (and it worked better)
I started doing media/codec work around 2007 and finding experienced media engineers at the time was difficult and had been for quite some time. It's always been hard - super specialized knowledge that you can only really pick up working at a company that does it often enough to invest in folks learning it. In my case we were at a company that did desktop video editing software so it made sense, but that's obviously uncommon.
dpe82··on macOS 26.2 enables fast AI clusters with RDMA over Thunderbolt
Yeah I'm familiar; I was hoping I could do something related on previous generation commodity(ish) hardware. It didn't work but I learned a ton.

> The main challenge is latency since you have to do much more frequent communication.

Earlier this year I experimented with building a cluster to do tensor parallelism across large cache CPUs (AMD EPYC 7773X have 768mb of L3). My thought was to keep an entire model in SRAM and take advantage of the crazy memory bandwidth between CPU cores and their cache, and use Infiniband between nodes for the scatter/gather operations.

Turns out the sum of intra-core latency and PCIe latency absolutely dominate. The Infiniband fabric is damn fast once you get data to it, but getting it there quickly is a struggle. CXL would help but I didn't have the budget for newer hardware. Perhaps modern Apple hardware is better for this than x86 stuff.

dpe82··on Is it a bubble?
A take I saw recently is: if people are still asking "are we in a bubble" then we are not yet in a bubble.
dpe82··on NVIDIA frenemy relation with OpenAI and Oracle
Maybe, but they'd been operating under that name for 7 years before Elon came along and decided he needed a name for his model.
dpe82··on Google Titans architecture, helping AI have long-term memory
I would imagine they do not want their researchers unnecessarily wasting time fighting for resources - within reason. And at Google, "within reason" can be pretty big.
dpe82··on Touching the Elephant – TPUs
That doesn't mean they won't try anyway; political ideology often trumps rational planning.
dpe82··on The Forgotten Roman Ruins of the ‘Pompeii of the Middle East’
It's not even noon and I've already thought about ancient Rome today!
dpe82··on IBM CEO says there is 'no way' spending on AI data centers will pay off
Maybe? The price difference on newer hardware can buy a lot of electricity, and if you aren't running stuff at 100% all the time the calculation changes again. Idle power draw on a brand new server isn't significantly different from one that's 5 years old.
dpe82··on Why Strong Consistency?
Your users must be very different from the ones I'm familiar with.
dpe82··on Why Strong Consistency?
P/B frames (which is usually most of them) reference other frames to compress motion effectively. So losing a packet doesn't mean a dropped frame, it means corruption that lasts until the next I-frame/slice. This can be seconds. If you've ever seen corrupt video that seems to "smear" wrong colors, etc. across the screen for a bunch of frames, that's what we're talking about here.
dpe82··on Go's Sweet 16
It really depends on product area.
dpe82··on Yann LeCun to depart Meta and launch AI startup focused on 'world models'
Of course the challenge with that is it's often not obvious until after quite a bit of work and refinement that something else is, in fact, better.
dpe82··on Iran faces unprecedented drought as water crisis hits Tehran
And immediately after Pearl Harbor the Germans rather stupidly declared war on the US.
dpe82··on Ask HN: What Are You Working On? (Nov 2025)
I'm building (yet another) 2d/3d parametric CAD tool. In-browser, collaborative, etc.
dpe82··on Iran faces unprecedented drought as water crisis hits Tehran
Germans committing genocide was not why the US entered the war, though.
dpe82··on Why aren't smart people happier?
The widely held notion that happiness (or lack thereof) is simply the result of chemical (im)balances is one of the greatest PR victories of the pharmaceutical industry.
