sgerenser··on A $20 drug in Europe requires a prescription and $800 in the U.S.
While it’s true that the U.S. spends way too much on healthcare (more than any other country as you said), the fact that it has a mediocre life expectancy is almost entirely due to things that have little to do with the quality of health care. Much more driving than most other countries resulting in more auto accidents and thus deaths, way more guns resulting in more murders and suicides, etc. Drug overdoses, in particular opiates, are probably the biggest one than can arguably be linked to healthcare.

Gov shutdown wasn’t about medicaid expansion, which is done at the state level. It was about expanding ACA subsidies to those making more than 400% of the federal poverty level.

Yeah this is something people in favor of single payer healthcare in the U.S. don’t want to acknowledge. In most other countries, the middle 50% of taxpayers pay a much higher percentage of their income than in the U.S. Everyone somehow thinks we can make it work just by raising taxes on “the rich” (where that is usually defined as anyone making more money than them). But if it was that easy, then why does Canada and most European countries have so much higher taxes on the middle class?

Now I’m not inherently against increasing taxes (for all) if it gave us a much better healthcare system, but you have to be intellectually honest about who would have to pay those higher taxes. It’s not just Elon Musk.

sgerenser··on RAM is so expensive, Samsung won't even sell it to Samsung
In the past using Snapdragon CPUs for the U.S. made sense due to Qualcomm having much better support for the CDMA frequencies needed by Verizon. Probably no longer relevant since the 5G transition though.

Where can you buy a new Thinkpad with 96GB and 4TB SSD for $2K? Prices are looking quite a bit higher than that for the P Series, at least on Lenovo.com in the U.S. And I don't see anything other than the P Series that lets you get 96GB of RAM.
sgerenser··on Advent of Compiler Optimisations 2025
-O3 gained a reputation of being more likely to "break" code, but in reality it was almost always "breaking" code that was invalid to start with (invoked undefined behavior). The problem is C and C++ have so many UB edge cases that a large volume of existing code may invoke UB in certain situations. So -O2 thus had a reputation of being more reliable. If you're sure your code doesn't invoke undefined behavior, though, then -O3 should be fine on a modern compiler.

sgerenser··on 250MWh 'Sand Battery' to start construction in Finland
Sounds like it didn’t go so well: In 2020, the system started showing signs of deterioration resulting in significant maintenance issues. System components, knowledge, and technical expertise for repairs were becoming increasingly challenging to find. In response to system failures, the Drake Landing Solar Company added redundancies to the system to be sure that homes in the community were receiving heat… In 2024, a decommissioning process for the Drake Landing Solar Community began, where the majority of the 52 homes were converted to natural gas-fired furnaces.

Nowadays, solar thermal collectors are completely obsolete except in very niche applications. Solar PV is so cheap that it’s literally cheaper (not to mention much less maintenance) to wire a bunch of PV panels to a resistance hot water heater than it is to directly heat the water with thermal collectors!

sgerenser··on Bring bathroom doors back to hotels
The worst thing I’ve found with positive reviews is ones that are obviously fake/incentivized. I looked up reviews recently for a hotel that I used to stay at a lot for work, and had gone way downhill with many issues (broken ACs, mold, leaking ceilings, etc.). I was curious if they ever fixed their problems. I was at first surprised that they had a fairly positive overall review rating. But looking deeper, the many negative reviews were just crowded out by obviously fake reviews. Dead giveaways: every single one named multiple people by name. “Dave at the front desk was just so friendly and welcoming! Barbara the housecleaner did a fantastic job cleaning. And Steve the bartender just made my day! I love this hotel! 5 stars!” (Almost) nobody reviewing a hotel for real does that.

Molten salt solar power plants are completely obsolete. See for ex. Ivanpah being shut down early because the power its generating is too expensive compared to Solar PV: https://www.renewableenergyworld.com/solar/once-an-engineeri...
sgerenser··on Helping Valve to power up Steam devices
People repeat this line a lot but I don’t think it’s true. Companies like Intel, AMD, Arm, Broadcom, etc. afaik all pay their software folks of equivalent YoE or level roughly the same as their hardware folks. To the extent there’s any difference, it’s much less than 25%.

OTOH, there’s a small slice of (mainly) software companies like Google and Meta, along with Unicorn private companies, that skew the average software engineer salary high. Then there’s a long tail of “old school” hardware companies like TI, Motorola, Atmel, Microchip, and tons of smaller less well known companies that all pay much lower than Google. But they pay their software people poorly as well.

So if you just look at “average software engineer salary” vs “average hardware engineer salary” it appears that SW people are making 50% more than HW people, but it’s not at the same companies.

sgerenser··on FEX-emu – Run x86 applications on ARM64 Linux devices
The latter is now an optional feature in the mainstream Arm ISA now (FEAT_FlagM and FEAT_FlagM2). Similarly the “alternate floating point mode” that Apple uses to match nuances of x86 FP semantics is a standard architectural feature as well. The TSO option though is Apples own thing.

sgerenser··on What happened to Transmeta, the last big dotcom IPO
It looks like rather than hiring a designer, they let one of their engineers (or worse, the CEO) design the Transmeta logo. I don’t know what that font is, but it might be even worse than Papyrus.
sgerenser··on I was right about dishwasher pods and now I can prove it [video]
We’re talking about heating the water, not drying. The discussion started with regards to energy used to heat water vs. using water from the hot water tap.
sgerenser··on I was right about dishwasher pods and now I can prove it [video]
CrystalDry is an “upsell” feature on the high end versions of their dishwashers for more efficient drying. It’s not the thing that they’re calling a heat pump, that’s the water pump that also does resistive heating. Bottom line is, Bosch (nor anyone else afaik) does not make dishwashers that are more efficient due to using “heat pump” technology.
sgerenser··on I was right about dishwasher pods and now I can prove it [video]
Bosch dishwashers are NOT heat pump dishwashers! They have a pump that also heats the water. They call it a “heat pump” but I find that terminology a bit strange, as its clearly not a heat pump (which is a term of art in appliances and HVAC). It’s just a resistive heater that is no more efficient than any other dishwasher heating element.
sgerenser··on I was right about dishwasher pods and now I can prove it [video]
Bosch dishwashers have something they call a “heat pump” that is a water pump that also heats the water with resistance heat. It’s not any more efficient than the normal heating coils in every other dishwasher, and it isn’t a “heat pump” that uses a refrigeration cycle (as one would use to e.g. heat their house).
sgerenser··on I was right about dishwasher pods and now I can prove it [video]
I think you’re confused, heat pump dishwashers are extremely rare even in Europe, and basically unavailable in the U.S.
sgerenser··on I was right about dishwasher pods and now I can prove it [video]
American dishwashers are always hooked up to the hot water supply. It’s right in the installation manual, and I’ve never seen one that wasn’t.
sgerenser··on Direct File won't happen in 2026, IRS tells states
That’s valid, but my comment was about why a (non-governmental) third party or charity wouldn’t want to take the open source Direct File software and run with it. If they aren’t actually the government running it, it completely loses its primary advantage.
sgerenser··on Direct File won't happen in 2026, IRS tells states
There are already ways to file your taxes for free or very cheap, e.g. https://www.freetaxusa.com. It would be hard for anyone to compete with a free or very cheap competitor, even as a nonprofit.
sgerenser··on Direct File won't happen in 2026, IRS tells states
Direct File did have a lot of limitations, so I assume when they say “eligible taxpayers” that’s the total number of people that could have used Direct File, which is much less than 100% of taxpayers. Even then, I’d assume more than 10 million people in the U.S. have very simple tax returns.
sgerenser··on Direct File won't happen in 2026, IRS tells states
There is actually a pretty massive tax evasion problem. Or at least the IRS is pretty sure there is, but they don’t have the resources to go after even a small fraction of them. The only thing that keeps people honest is the worry that if they lie, the IRS might already know (based on e.g. 1099 reports that go to the IRS), or they’ll get audited (which actually happens very infrequently).
sgerenser··on IBM cutting thousands of jobs in the fourth quarter
Surprisingly, the article doesn't say it's because of AI (although it does mention a previous layoff of 200 HR employees was due to replacement by "AI Agents").
sgerenser··on When O3 is 2x slower than O2
"Haswell or newer" is a bit misleading here, because there were low-end Celerons and Pentiums shipped for years after the release of Haswell that lacked AVX2 and wouldn't be able to run software compiled for -march=haswell.
sgerenser··on Guideline has been acquired by Gusto
If you’re an senior+ software dev in the US there’s a good chance you’re already over the social security payroll tax cap, and if so you’re really only saving the Medicare tax of 1.45% on up to $8000 for a family plan. It’s not nothing but not worth dealing with a crappy provider to get.
sgerenser··on My Impressions of the MacBook Pro M4
No, I believe the issue is Apple limits the top half or so of the brightness/backlight level for HDR content only. The apps allow it to be used for normal non-HDR content.
