Ironically, there have been several crypto wallets that use much better hardware security, but they can't beat Ledger on marketing.

Equity holders have a more junior claim than debt holders, but if there are enough dollars in the bankrupt company to make the debt holders whole, the equity holders get whatever is left over (obviously in order of seniority).

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.

BSD/MIT are functionally equivalent to “sign away your rights.”

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.

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.

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).

$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.

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.

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.

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.

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.

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.”

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.
