pclmulqdq··on Owed a billion dollars in Nvidia stock
That’s not how the real world works. Sometimes the chance of winning is actually 0, and sometimes when you pursue something frivolously you actually end up having to pay the other side’s fees. The EV of a lawsuit can easily be less than 0.

There’s already a relatively liquid market here around legal financing, but they only finance cases that can win. This is not a case that will result in anything but a dismissal.
pclmulqdq··on Nobody pays for FOSS, we can force them to
BSD/MIT are functionally equivalent to “sign away your rights.”
pclmulqdq··on Nobody pays for FOSS, we can force them to
Accepting contributions when you do this is a bit weird. They need to sign away their rights to their code so you can sell it. This is why the “open-source” database companies (all of which dual-license) don’t accept contributions.
pclmulqdq··on Starlink Signal Leakage Threatens Radio Astronomy's Most Critical Frequencies
Cubesats can’t take very good pictures. You need a big mirror to get really clear imagery and you can’t cram one of those in a cubesat. Space telescopes are by nature massive, heavy satellites unless they aren’t intended to look very far or see very much. The other option is to cheaply build something absolutely massive on Earth.
pclmulqdq··on Lawmakers added $1 to car insurance policies. That money paid for Flock cameras
In 2021, Kyle Carruth shot someone on his porch and used a castle doctrine argument in his defense, and he was not indicted. That would suggest that the porch is considered part of the habitation separate from an attempt to enter. I think the thing you are citing as an authority here is the opinion of a law firm and not a case, and not necessarily a good one (law firms run the gamut from "alcohol addict in a strip mall" to big law).
pclmulqdq··on Is mathematics about to enter the conservatory?
$40/hour is not bad. Aside from the few thousand tenured orchestra/chorus musicians, none of them are going to be making 6 figures from one job, but a number of musician-musician households pull in over $100k between two incomes built around relatively unstable gig work without either one having a high-prestige job.

Also note that churches, which are a hub for working-class musicians, are exempt from BLS reporting.

Most of the major orchestras have a union and they negotiate salaries in the $100-200k range for everyone. It’s a lot more people than you might think (70-150 people on payroll in each orchestra). There are also a lot of touring soloists in the world compared to what you expect. It’s a very stressful life, but it yields somewhere between $100k and $1M per year, and many of your living expenses are fully paid for on top of that.

There are at least 20 such orchestras in the US alone, not to mention all the orchestras in Europe and Asia. There’s also a very long tail with compensation down to $50k for players.

The US BLS has 35,000 paid musicians listed, with another 10,000 music directors (a lot of church organists are in this category). Median wage of $40/hour, mean of around $52.

pclmulqdq··on Intrusive linked lists (2019)
I was surprised to see the main benefit of intrusive linking mentioned as a bit of a side note: The ability to move data around between lists (and within a list) without copying. You also get O(1) removal from the middle of the list, assuming you have a pointer to the object somewhere else. As a result, when you have large state structs and you don't do a lot of list scans, intrusive linking makes things a lot faster than use of packed structures like vectors.

I think this has applied in the case of self defense in Texas, at least on someone’s porch. Curtilage is a general concept, not specific to the fourth amendment.

Are you sure that doesn't qualify on the basis that it is the curtilage of your home? Often this counts as "in your dwelling" because it's in your private space that immediately accompanies the dwelling.
pclmulqdq··on Actinide is first startup to produce high-assay low-enriched uranium (HALEU)
This is a bit uncharitable to the concept of a centrifuge here. The Iranian nuclear program seems to have centrifuges that are a lot smaller and cheaper, and you can certainly build one that meets these needs.
pclmulqdq··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
I am pretty sure that's a feature, not a problem. The idea of these chips is to rush to idle on webpage-like workloads, and then otherwise use as little idle power as possible. Games and heavy work are generally not the intended workload.
pclmulqdq··on The Mysterious Syndrome Destroying Endurance Athletes
Note that in the only reasonably-close-to-contemporary story of the run, the marathon run itself came at the end of a multi-day run from Marathon to Sparta and back, about a 300 mile round trip. The marathon run was just the last 26.2.
pclmulqdq··on RISC-V: They Should Have Known Better
By volume, I would expect the majority of microcontroller silicon shipped to be these kinds of deeply embedded cores. They even show up in chips called “microcontrollers.”
pclmulqdq··on Can Intel finally beat ARM on performance per Watt?
Quite a lot of web rendering is done with non-integer JS Number types, aka FP64. You are right that there’s a 31-bit integer optimization, but once you have a non-integer in the mix, it’s FP64. Many GUIs some time ago would use FP32, but in 2026 there’s a lot more FP64 out there than you give credit for.
pclmulqdq··on Analyzing data from Silicon Valley ventures and founders prosecuted for fraud
Supposedly B2B SaaS companies in YC have been known to enter into agreements to “buy” each others’ products so they can all book more users and revenue despite a single dollar not changing hands.
pclmulqdq··on Can Intel finally beat ARM on performance per Watt?
AI is not the only thing in the world. The rendering of this webpage involves a lot of FP64 work.
pclmulqdq··on Can Intel finally beat ARM on performance per Watt?
Literally every workload not named above. It’s the default for a non-integer number.

* Web rendering and almost all web apps (see the JS number type)

* Most things in a game not done on the GPU

* Audio processing

* Most GUI processing/rendering

* Every miscellaneous/scalar calculation these days

Believe it or not, on a CPU this adds up to a lot more than the work you get doing AI processing.

pclmulqdq··on Can Intel finally beat ARM on performance per Watt?
What? Pretty much every general-purpose calculation on your computer that isn’t an integer is done with FP64. AI may not use it and games may prefer FP32 for many things, but your CPU certainly does a ton of FP64 work.
pclmulqdq··on US Military's cyber command unit grapples with cluster of deaths by suicide
At least one of those American citizens was the intended target of a drone strike.
pclmulqdq··on SpaceX Starship Flight 13 livestream [video]
I am pretty unconvinced that any of the past explosions of starship used that feature. It’s very convenient to have an “explode” button so you can say all of your rocket detonations were intentional, but they are often leaking fuel or dropping chunks before they explode.

This was a great flight, though.

pclmulqdq··on What I learned selling 2,500 MIDI recorders: Hardware is not so hard
It does still need CE certification and emissions testing. I’m guessing they didn’t do that and it will be fine because they only sold 2,500 units.
pclmulqdq··on NYC may require landlords and realtors to disclose the use of AI in listings
There is square footage on many NYC listings, but it’s wrong. They often have the square footage of the total area occupied by the apartment, including all the interior walls and columns that can take 20% of the area away.
pclmulqdq··on Kimi K3, and what we can still learn from the pelican benchmark
It is. All over the Arab world, imagery in ads is “backwards” and I believe several companies will flip their ads horizontally, and UI localization involves flipping graphics.
pclmulqdq··on Since Chromium 148, Math.tanh is now fingerprintable to link underlying OS
I go to the conference frequently and know the organizing committee. It depends on the year (2025 and 2026 did it, but not 2024). And if someone decides to register arith20xx.org, I doubt the conference would buy it.
pclmulqdq··on SpaceX wants to launch 100k more Starlink satellites for 100x the bandwidth
Starlink was an attempt to grab the rural broadband funding that supported that fiber rollout in the US. It was too slow, so the money went to fiber and traditional ISPs instead. Fiber may well have come faster without starlink.
pclmulqdq··on Cursed circuits #5: capacitance multiplier
Wait until he hears about negative Miller capacitance.
pclmulqdq··on [dead]
This page reads like someone had ChatGPT write an article about the economy being K-shaped and then had ChatGPT summarize it as bullet points. Somehow that feels more offensive than just a bad article.
pclmulqdq··on Reality has a surprising amount of detail (2017)
Yeah, that is correct. Sawmills often produce only one or two grades of wood and don’t do aggressive binning. That’s why the quality is so variable within the grade. There are also factors that affect the grade but don’t necessarily impact every application (eg warping and knots are sometimes ok), so the bins are coarse-grained.
