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.

The threat of breaking all encryption has been a slow-burning $1 trillion or more grift for the field over the last 20-30 years. Not that anything has materialized from it. I am somewhat convinced that PQC is primarily being rolled out so that we can all stop funding those clowns (and because lattice-based cryptography is finally ready for prime time).

They aren’t “knowingly selling you poor quality” as some sort of scam. They are selling you wood to the spec you asked for. If you want higher-grade wood, you either have to spend money getting lumber graded to a higher spec or spend the time going through piles of low-spec boards to find the good ones. Many engineered wood structures are designed to use “poor-quality” wood, and they prefer it because it’s cheaper than using less high-grade wood.

The ones that use an OS generally use seL4 these days.

I think you might be surprised that Linux is generally not involved in safety-critical systems. There is a whole separate ecosystem for those applications.

Literally any product you send to the consumer can be reverse-engineered at comparatively low cost. The world doesn’t just revolve around server-side software.

This sounds like it is working as intended. The patent comes early in the process to protect all the commercialization investment. Patents are intended to be filed early in the process, and they gain value as the invention proves its worth. Note also that you can patent a mining claim before pulling a single precious gem or mineral out of the ground.

If a piece of software is in safety-critical applications these days, it is often required to have a proof of correctness.

That business idea is already taken. It’s OnlyFans and it has more revenue than a top 10 company on the US stock market.

I did some baroque harpsichord tuning in my past. Nobody I knew in the field of baroque keyboard tuning had absolute pitch, because it would drive you crazy if you did with all the wandering A's. When you want to flex between A=440, A=430, and A=415 (392 is a lot less common) regularly and your ear is tuned to a 440 A, I hear it gets really annoying because everything seems flat. In comparison, a huge number of piano tuners and organ tuners have absolute pitch.

I really doubt it, and I am not surprised that apps didn't work. I also don't think playing a musical instrument actually gives as much insight here as you want - it's a very indirect transfer if you're learning via classical methods or if you are learning purely by reading. Jazz and contemporary methods involve a lot more "listen, then play back" rather than reading. If you want to work on ear training and theory, cross-training with some jazz or contemporary helps a lot.

The way music schools teach this is relatively brutal and annoying, with a _lot_ of repetition and testing (eg "sing a major second above this note" and "identify the interval" questions), but I am not sure any other method works. At the same time, everyone going through an ear training curriculum does pick up decent relative pitch. This can take a year or two for college music majors, so it's not exactly a casual exercise. However, I assume the major barrier to entry is not musical aptitude but willingness to put up with bullshit, because it feels like bullshit when you are doing it.

Everyone can learn good relative pitch with practice. Music schools do this regularly, and it's just a skill you can pick up. Start by identifying intervals, then learn chords, and then learn to write down music you hear, and so on. It just takes work.

If you mean “cities” then yes. Google the word “favela” if you want to see how things work in Brazil.

Yes, Tesla was ridiculous at the time, but Tesla’s valuation at the time is normal for tech companies these days. However, the main comparison, which Elon has been trying desperately to escape, is traditional automakers. If you compare how out-of-line Tesla’s PE and PS ratios are against Toyota and other car makers, it’s about the same ratio as SpaceX to tech companies today.

We all said that about Tesla for years, and a lot of people got burned on the trade. This time may be different, but it also may not be.

This is why they cane people in Singapore for nuisance crime. Incarceration is expensive and fines don’t have the right effect.

That test had several hapax legomena on it, so it would make sense.

The Brazilian government keeps the crime contained to specific areas, where it gets extremely bad. In the US, a generalized lack of enforcement means small amounts of nuisance crime spread around.

I think the test was vibe coded, because a xylologist is someone who studies wood, not someone who sells wood. I am not sure if "xylolgist" was the exact word, though.

xylo- = wood; -logy = study

Indeed from M-W: "a branch of dendrology dealing with the gross and the minute structure of wood"

I also got something around 70-80k with 95/100 correct words (I don't know or use most of these words, but the later sections have a lot of words with Greek or Latin origin, which made them easy to guess). One of my wrong words was a misclick in the first section, which I think dragged down the estimate quite a lot. You may have done something similar. I assume they use a simple formula where early misses cost you a lot and late misses cost you very little.

Concretely, the company is not a single founder and his cronies. The company is a pile of paperwork (aka contracts) that dictate the relationships between (thousands of) people who are all involved in the enterprise, from factory workers and entry-level coders to investors. It is that pile of paper and the relationships it encodes that creates an output that is larger than the sum of its parts.

You can worry about whether the split of return is correct, but arguing that the pile of paperwork is valueless or somehow nonexistent is silly. Value flowing to investors is a consequence of how that pile of paperwork is set up and what is on the papers, nothing more or less.

The system set up by the company is what earns the company value and creates it for others. Individual workers implement critical parts of that system, but the work of the workers does not on its own create the value. AOC and PG are both a bit obtuse about this.

The RISC-V foundation and related companies also got a bunch of money from Europe. I am not so sure this was about leaving a repressive regime as much as chasing the European "homegrown computing" money.

Not if they are dressed up in a particular way, and not if intelligence is genuinely relevant. I have done a few of these tests for jobs in the US before. They are just bad.

Ferrari doors are always this bad. If you regularly transport more than 2 people in your Ferrari, you aren't their target market.

The look is nothing less than I would expect from "make it thinner and round the corners" pioneer Jony Ive.

I don't know why people insist on EVs being kind of ugly and boxy, but Ferrari had a chance to do better and didn't.

"Printing cash" is generous given the expenses and attempted $2 trillion valuation.

I will note that you listed out all of the RVA23 instruction extensions, not all of the blessed RISC-V instruction set extensions. Here's the list of every ratified RISC-V instruction set extension, to get parity with the list you gave for the other ISAs:

M, A, F, D, Q, C, B, H, Zicsr, Zifencei, Zicntr, Zihpm, Zihintpause, Zihintntl, Zicbom, Zicbop, Zicboz, Zicond, Zicfilp, Zicfiss, Zimop, Zca, Zcb, Zcd, Zce, Zcf, Zcmp, Zcmt, Zcmop, Zclsd, Zilsd, Zmmul, Zfh, Zfhmin, Zfa, Zfbfmin, Zfinx, Zdinx, Zhinx, Zhinxmin, Zaamo, Zalrsc, Zawrs, Zacas, Zabha, Zalasr, Zba, Zbb, Zbc, Zbs, Ztso, Zbkb, Zbkc, Zbkx, Zknd, Zkne, Zknh, Zksed, Zksh, Zkn, Zks, Zkt, Zk, Zkr, Zve32x, Zve32f, Zve64x, Zve64f, Zve64d, Zve, Zvl32b, Zvl64b, Zvl128b, Zvl256b, Zvl512b, Zvl1024b, Zvl, Zv, Zvfh, Zvfhmin, Zvfbfmin, Zvfbfwma, Zvbb, Zvbc, Zvkb, Zvkg, Zvkn, Zvknc, Zvkned, Zvkng, Zvknha, Zvknhb, Zvks, Zvksc, Zvksed, Zvksg, Zvksh, Zvkt, Sm1p11, Sm1p12, Sm1p13, Smaia, Smepmp, Smstateen, Smcdeleg, Smcsrind, Smcntrpmf, Smrnmi, Smdbltrp, Smmpm, Smnpm, Smctr, Ss1p11, Ss1p12, Ss1p13, Ssaia, Ssccfg, Sscsrind, Sscofpmf, Sstc, Ssqosid, Ssdbltrp, Ssnpm, Sspm, Ssctr, Supm, Sv32, Sv39, Sv48, Sv57, Svinval, Svnapot, Svpbmt, Svadu, Svvptc, Svrsw60t59b, Sdext, Sdtrig

That doesn't look very short to me.

These are grouped into profiles, like "Skylake" or "Cortex-M33" or "Neoverse-N1." The main issue for RISC-V isn't the number of instruction set extensions, it's the number of profiles. RVA23 is one single blessed profile, but many chips will add a few more instructions or include fewer than RVA23 based on age of the chip.

It's way worse on RISC-V. There are maybe 5 x86 or ARM variants to care about at any given time, even if you want to hyper-optimize your code. RISC-V has a soup of literally 100s of extensions with non-uniform use and support.

I think Nate Silver is off the mark as to what Disney wanted to get out of this. Entertainment companies like Disney make plays where they buy a huge portfolio of entertainment assets and see which ones manage to hit it big. They invest resources and they help quite a lot, but it does come down to the entertainer to take it all the way. In other words, a Disney executive probably bought 538 expecting that it might become the next CNN or Fox - the next big secondary source news analysis platform. Note that Disney doesn't have one of those in their portfolio right now. Instead, 538 continued to produce wonkish articles about esoterica of sports and politics statistics, and did not expand to the grand role that Disney may have imagined. The ad revenue from some wonkish articles isn't going to cover the cost of a number of writers and statisticians, which is why Nate Silver went to a bigger player in the first place.

The core problem here seems to be that the visions of the buyers were not aligned with Nate Silver's vision. He wanted to continue having a blog on esoteric statistics, but with the resources of a news network. They may have wanted to have a news network, and acquire it at the price of a blog on esoteric statistics. This wasn't a loss-leading "feather in the cap" for Disney, but a bet that simply didn't pay off and needed to be put out to pasture.
