It's 2025 and the simd operations in this aren't that obscure. So I wonder how close std::simd gets to the instrinsics' performance with clang and gcc.

There is a high likelihood this ruling gets overturned. The title and the article use the term “book ban” but gloss over what’s actually happening which is legally significant:

> HB 1069 required that school librarians remove materials from their collections that contain “sexual content,” regardless of the value of the book

Florida cannot ban private libraries from stocking books with sexual content. But librarians are government employees buying books and maintaining libraries with government money. The state can direct its employees what kinds of books to make available for the same reason any private entity can do so.

This might be different if libraries were neutral venues for authors to come present about their books. In that case you might have a case about viewpoint discrimination. But the first amendment can’t force the government to buy particular books and make them available to the public.

From the statute, "As used in this subsection, the term “school property” means the grounds or facility of any kindergarten, elementary school, middle school, junior high school, or secondary school, whether public or nonpublic."

Massimo invented this technology (yay Massimo!) in the 90s yet their Japanese patents [1] weren't considered prior art (WTF?) because of technical legal reasons.

[1] https://patents.google.com/patent/JP2002542493A5/en%EF%BF%BC

So I suppose if Massimo is going to use a technical legality to extend then Apple can use a technical legality to avoid.

People reading the book and being into it and telling other people.

It’s also a hard book to read so it may be smart kids trying to signal being smart.

Fountainhead is written at the 7th grade reading level. Its Lexile level is 780L. It's long and that's about it. By comparison, 1984 is 1090L.
CalChris commented on Why tail-recursive functions are loops   kmicinski.com/functional-... · Posted by u/speckx

Practically the day after I learned about tail recursion in CS class, I learned that almost all recursive calls can be translated to iteration, that in many cases the iterative version is easier to scan, is as fast if not faster, and that they can usually handle much much larger inputs than recursion due to avoiding stack overflow.

Tail recursion is meant to fix the latter. But what we mean to happen and what actually happens ain't ever exactly similar.

Tail recursion IME is a bigger foot gun than relying on someone to add a new conditional branch at the end of a block in an iterative algorithm without fucking it up in the process. And iteration responds generally better to Extract Function. And while I can think of counter cases easily enough, in the large iteration is less work and less vigilance. And you cannot scale a project up without the vigilance requirement amortizing basically to 0 per line of code.

I must have missed this class. How does one convert a recursive descent parser into an iterative one?

Look, I'm not agreeing with this admin's policy direction, and I certainly don't want the world they envision that this policy will drive us toward—there's plenty of reasonable skepticism that it won't even have the desired knock on effects they're hoping for, but I do think the folks at the helm know broadly what the levers they're pulling do. I worry the level of stupidity that their critics project on them is both inaccurate and is so severe as to essentially excuse their actions and absolve them of any responsibility for them.
CalChris · 13 days ago
We disagree. To reduce it to a few words, I think that you see policy (even if misguided policy) and I just see populism, entertainment if you will. I think the purpose of the article is to remind us what mercantilism is. But again, I don't see this as mercantilism which has a coherence, and instead just as populism which doesn't.

Putting a heroin addict in charge of Health and Human Services and shutting down vaccine development is not policy. It's populism.

The orange figurehead, probably not, but the people actually pulling the strings and writing all those executive orders absolutely do. The folks in power might be misguided but they are acting purposely creating more protectionist policies. To what end I think is anyone's guess. I don't think it's clear how an isolationist US benefits us when right now we have every country in the world giving us real tangible wealth in exchange for paper.

> absolutely do

I'm not convinced. There is no coherence in their decisions, well any more than tossing out red meat. We can't even call them protectionist policies. It's just populism.

Still, I agree about isolationist. But we started down that road with W and are now running off that cliff with Trump. Not coherently but enthusiastically.

1.2B went to investors, the remaining 1.2B was actually an incentive/payout for the founders/employees that google took. The company basically has whatever money it had in the bank, plus a bit more from Google - but no investor liabilities.
CalChris · 16 days ago
Ok, Google can pay $1.2B to the CEO and key employees to get them to walk. The other $1.2B is for the Windsurf IP and it cannot go directly to the investors. It has to go through the company where it is first revenue and then an asset.

But Windsurf could distribute profit at this point before the Cognition deal. I guess this is where the preference rights got exercised. The tweet from employee #2 said his stock wasn't worth anything. Actually, he got preferenced out of the $1.2B in dividends.

Then came the $250M Cognition deal. He got preferenced out of the proceeds of the Cognition deal as well.

> My question is what happened to the $2.4B

We don't know what deal they made with the VCs, but they could have multiple liquidation preference agreements.

> A liquidation preference multiple (e.g., 1x, 2x) determines how much investors receive before any distribution to common shareholders. A 2x preference means investors are entitled to twice their initial investment amount before others receive payouts.

So Google writes a check for $2.4B to Windsurf and gets the IP. Check deposited with Windsurf. Ledger entries made. Windsurf now has $2.4B in assets more than it had before. Money in the bank. Preference cliffs do not apply to this licensing deal. Key employees and CEO then take a 2.4 mile hike over to Google. Lunch is served.

Then Cognition offers $250M for Windsurf itself. Ok, I can imagine the preference cliffs kicking in now. But Windsurf just got a check for $2.4B and I don't think they had anywhere close to that in liabilities.

So where'd the $2.4B go? This seems like a strange deal.

  openai's $3b acquisition of windsurf falls apart. after months of negotiations, they walk away.
That isn't accurate. Microsoft was an OpenAI investor and had rights and for MS reasons, exercised them. That's what killed the deal.

  google announces they're paying $2.4b to hire windsurf's ceo and 41 researchers for deepmind. not to acquire windsurf. just the humans. the same day openai walks. what a coincidence!
That isn't accurate as well. Google also licensed the Windsurf IP.

My question is what happened to the $2.4B? Apparently very little of it made its way to the Windsurf employees, as #2 tweeted last week. It wasn't an acquisition although Cognition was. Cognition bought a company for $250M that just got a check for $2.4B. How exactly did this work?
