hn_acc1··on The Legend of von Neumann (1973) [pdf]
Not sure that it would be worse than letting the other end of the spectrum be in charge of it, as we've seen..
hn_acc1··on Court agrees with EFF: Utah's VPN law demands a technical impossibility
I've found that some sites (even like restaurants, for example) have no problem setting up an order when I connect via my VPN (from Linux) - my default browsing setup. But when I go to pay, their payment processor refuses to work properly / fails, so I can't actually transact any $$. Others work just fine WITH VPN on. Sadly, the former is increasing and the latter decreasing, to the point it's getting harder and harder.

Heck, Lowes and BestBuy are pretty unusable in general via VPN already.. (or maybe due to ublock, or privacy badger or eff, etc.. :-)

hn_acc1··on Court agrees with EFF: Utah's VPN law demands a technical impossibility
We have a data center in Utah.. And I'm sure some of our customers are storing "adult" material.. Are we now banned?
hn_acc1··on Court agrees with EFF: Utah's VPN law demands a technical impossibility
Next it will be illegal for anyone to visit an adult website from some states, even with proof of age, kinda like Prohibition..
hn_acc1··on Returning from vacation? The government can search your phone without a warrant
GAVE, not gives - past tense. What good is an amendment if the govt can ignore it at will (2025+) and you can't sue successfully because SCOTUS will find some made up reason to make you lose?
hn_acc1··on GPT-Synopsys: Frontier Intelligence to Revolutionize Chip Design
Can 3D printers print with 1 micrometer (not millimeter) accuracy? 1 micron gets you things like the original 8086. Oh wait, current best desktop printers get like 100 micron (0.1 mm) accuracy. So scale up what we have now 100x in terms of accuracy (imagine how much bigger / more precise the motors, magnets, everything has to be). EASILY 10-50x the cost of a good home 3D printer today - say $50K. And 8086? Your phone is faster than probably 50-100 of them in parallel today) - so $100K (materials aren't cheap) to print a series of chips that were insanely obsolete 20 years ago and 1 $500 fpga could run circles around. Then scale that up at least another 50x to get semi-competitive (20 nm). There's a reason they put fabs in places like Arizona where there are relatively few earthquakes... Even the garbage truck driving past your house could damage your chip.

As far as home printing stuff: the clean room requirements are INSANE: just the HF (hydrofluoric acid) is crazy bad stuff that you could NOT get certified for general consumer use, no way, no how. And even if you did, you'd be crazy to buy something that comes with HF as part of the process.. And that's just ONE bad, bad chemical used by TSMC all the time.

FPGAs are the "faster-than-software / can make a custom chip" compromise - companies like Intel used to (not sure if they still do) use a ton of FGPAs to simulate new chip designs. Precisely because manufacturing state-of-the-art chips is so hard.

hn_acc1··on GPT-Synopsys: Frontier Intelligence to Revolutionize Chip Design
When TSMC capacity is already sold out for a couple of years, and demand just for plain RAM is through the roof, where will these "more chips" be actually fabbed?
hn_acc1··on The last time my family was replaced by technology
Is that in cash, so if the stock market drops 80%, it's still true?
hn_acc1··on Livenerf: Has Opus 5.5 been nerfed yet?
I did a deep dive into NiMH batteries a few years ago and concluded that most people felt similarly: you can often get "good" (similar to Eneloop) specs for a short run from almost any manufacturer at the outset (see Ikea Ladda batteries - suspected of relabeled Eneloop for a while, but now not as good), but consistent quality is pretty much only Eneloop or other name brand, with Eneloop generally being the best.

In the interests of saving my sanity and time (it's not free!) having to chase down which batch of which brand is "good" at the moment, I just decided on Eneloop all the time. Sure, we now have like 100-120 or something (wife likes flameless candles - just bought another 16-pack AAs) and I COULD maybe have saved $200 by buying dirt cheap. But all the time spent debugging flaky batteries, having the spouse complain, etc wasn't worth it to me (I get paid reasonably well).

hn_acc1··on Vermont replacing power plants with home batteries
How much for a decent home battery setup? Already have 15-year-old 4.2 kW system and lately, PG&E isn't really giving us anything for our power..
hn_acc1··on The End of a Fair Price: Dynamic Pricing and the Normalization of Gouging
I've only ever rented a room back in my college/intern days, so I have no context exactly, but from coworkers here in the valley, even the rent on those types of apartments keeps going up ridiculous amounts so that they keep moving..
hn_acc1··on Gemini 4 Argon
I know someone who works for Google Canada with AI. Her parents and mine were friends and some thought something might happen there at one point in time..

Dang, you sound like you were in school in Ontario at the same time as me? I also graduated from grade 13 in 1989...
hn_acc1··on The End of a Fair Price: Dynamic Pricing and the Normalization of Gouging
What kind of tools would help renters? This "just one penny less than they will bear" is part of the problem of modern society. There used to be SOME areas you could "win" a little. Pay a reasonable price for rent, not exactly 33.3333% of your income. Pay a reasonable price for a car, not 25.0% of your income, etc. Save a few percent here, a few percent there, and you could eventually get a downpayment on a house, or indulge in a hobby.

The endgame for these ghouls is to have you work 996+ and spend 99.9999999...% of your income on just the bare essentials so that there's not one penny left unmonetized for you to just exist, and nothing left for any type of enjoyment.

hn_acc1··on The End of a Fair Price: Dynamic Pricing and the Normalization of Gouging
Sure, but insurance companies also routinely pay only part of the cost - I.e. if the hospital has evaluated that a CAT scan costs them $1250 to do, and they need a small profit margin (make up your own numbers), they need to bill the insurance $3300 just to get $1400 paid out. Insurances routinely only cover a certain percentage of the cost (to save $$), so hospitals have to bill more to get the $$ they need.

And I'm not saying the hospital is innocent here, but this "costs more when billed to insurance" is a long-known issue.

hn_acc1··on Sex, AI, and the Apocalypse
I've had an internet email address since the late 80s, BBSing since the early 80s, pretty active online compared to many people I know who are also software people, especially for my age..

Had to google to figure out the abbreviation and look at the summary. I HAD heard the name before, but that's about it.

So does this host the files? For free? How long before ads start / you have to register / subscription model, etc?
hn_acc1··on How much oil-market buffer is left?
>If you can charge at home then trading in for an EV makes sense. Electric at home is vastly cheaper than fuel. If you can't charge at home, electric prices are all over, generally cheaper, but often not by enough to be worth the bother.

Sadly, in CA, charging at home (minimum $0.26/kWh) isn't that much cheaper. Sure, maybe half the price of fueling up an efficient gas car, but not like 5x cheaper or anything..

hn_acc1··on Let's make quality the norm again
Yeah, not sure I would rely on that.. Sure, they have Knipex and Klein on the approved list (which, AFAIK, is true), but then they list Warby Parker (read reddit - has gone WAY downhill), Cutco (by all accounts, a total rip-off and super low-quality knives requiring you to constantly get them sharpened) and Henkels, which also makes some pretty suspect knives, AFAIK.
hn_acc1··on Coyote v. Acme (1990)
I loved it too, and my daughters (who had access to several looney toons collections as kids) also seemed to enjoy it.
hn_acc1··on Apple Unveils iPhone Duo
To do what? I usually hold it with my left and, and one-finger (right-hand index finger) to type / scroll / select / etc. I guess I never "got" the phone model properly or something. My daughters type way faster on their phones, I can't do thumb typing (how do you hit those letters?!?), plus my thumbs get too sore too fast (decades on the edge of carpal tunnel) and/or cramp up.

I was timed at 140+ wpm in high school and online tests / etc have hit close to 200 wpm on a Qwerty. So I CAN touch-type and do it well - and keyboard + mouse is my goto jam. My favorite phone (alas, discontinued way too soon) was the Photon Q (work gave us phones way back) with slide-out physical keyboard.

I "use" an S21, but even just entering my 4-digit pin is awkward with my left thumb - is there some other way to hold it? I can't even imagine trying it with my right.. My thumbs just cramp up..

Have you been living under a rock? None of the big tech companies care one bit about user privacy in the US.
hn_acc1··on Navier-Stokes – Tristan Buckmaster [pdf]
Even if they claim not to use it, they're probably using it and hoping they don't get caught. They have zero ethics or morals, they just want to "win" to get mega-rich.

How many people can afford to take a day off work if they don't have flex hours?
hn_acc1··on 9000 RPM is faster than your screen refreshes
I'm even more impressed by purely mechanical engines of the 50s and 60s that revved that high without any help from microprocessors/fuel injectors/coil packs. Porsche built a 9000 rpm race engine that had beveled gears (I had to look it up) to ensure good timing. The 550 Spyder (and apparently later 356 "hot" versions) revved up to around 8000 rpm.
hn_acc1··on Dwarf Fortress' creator says the industry's in shambles over AI
I've worked for a few companies from 2000-2026 (2 startups, 2 medium companies), and overall, I would say they all had decent to great leadership. None of them were out to only maximize next quarter, all stressed being 100% honest with the customer, even if it meant disappointing them (i.e. we can't quite make that target, here's what we can do - this was for a consulting company), etc., and they were all trying to make the company grow AND be sustainable.

One startup didn't go too far (folded after 3 years), one grew to ~20 people, lasted for maybe 20 years total, I left after 2 years during the dot com crash.

Both of the medium companies are bigger now (I'm still working for one), and have generally positive outlook. I mean, you can't consistently be #1 in your industry when there are 2 companies with combined > 50 or 60% market share and roughly equal - some quarters, your competitor's 2-3 year plan will finish and deliver better for that quarter than your previous (now "old") product that is in the middle of a 2-3 plan, etc..

So they are out there, but it's RARELY in the "high profile" (FAANG/whatever) "move fast, break things" companies that you hear about a lot or that everyone wants to work for.

A friend said <ride sharing company> was like Game of Thrones come to life in a corporate setting, for example. Yet, some people got rich off it, I'm sure.

Or maybe there are more things using the same tactics / scammer's reach keeps increasing.

My parents "fell" for fundamentalism early (as kids - raised in it), for televangelists in their 40s, and Fox News in their 70s/80s. Fox News so recently only because they didn't get it very often until about 10 years ago when they moved into a retirement home (didn't have cable before that).

They arguably have more free speech rights than the average person with citizens united..
hn_acc1··on Processing in Memory: DRAM Is About to Do Math
Duncan Elliott taught my graduate (IIRC) computer architecture course while writing that thesis - we all talked about C-RAM for a while.. And I think it was a rehash of an even older paper / discussion about that idea.
