There's one thing in there worth discussing IMO: the focus on zero values (incl. nil). That's the Go mistake, the one that causes most of the issues for the intended audience, the one that can't really be fixed. It's a s

Not being able to create new code at runtime is a pretty huge freepass for the compiler to implement stuff a certain way. You can bet the Go compiler and runtime leverage that assumption.

A stack is actually LIFO? Otherwise, yeah, if you remove elements from the middle, you either need a structure that allows it, or you amortize it by making such updates less frequent. Still not a queue.

Right. And apparently, the best way to reverse that situation is to ignore Mozilla (or any other player with single digit market share) at the W3C? And do what instead? Side with Apple/Microsoft as long it hurts Google?

Pending exists to prevent writer starvation: if there's always at least one reader, no one can ever write. You take pending before exclusive (which should always be possible because you have reserved by then), and you should check pend

Otherwise it wouldn't get used. I mean get this great auto complete; if you use it, your code might be AGPLed for all you know, and you're in violation, because you didn't even add a notice. Would you pay for that?

Taken to its conclusion, liability is then on everyone who decides to publish anything that ChatGPT “tells” them, because it might cross the threshold on plagiarism. Are the OpenAIs of the world ready to shield their customers from th

They still do, for the most part. Anything else may be allowed, if it makes sense for the task at hand, but it's an uphill fight.

They may cancel it. But if they do, the bank loses their mobile apps, of which they built one (so far) that ports nicely to iOS and Android. Then they make new ones. What else should they have used? At some point worrying that things will b

Well, the difference isn't that great. You wrote: “the memory associated with the old version could be freed once nothing would want to access it again.” So all it really takes is something wanting.

Still that's what they're called: https://en.wikipedia.org/wiki/Persistent_data_structure Precisely because previous versions remain valid (persist) under modification.

If you read the article though, many of the updated nodes (which are now garbage) don't see any updates to their “data” but to internal tree pointers. So lots of “data” is being copied, and garbage is being generated, only for the bene

100% agree. Remote VSCode over SSH is great. The resource consumption on the client doesn't bother me one bit. Any minimally decent laptop can put up with that load, on battery power, for hours. I would agree with “whatever it takes to

If you're interested, both SQLite's and my memdb VFSes implement safe locking. Depending on your familiarity with Go, mine maybe easier to follow, or not. https://github.com/ncruces/go-sqlite3/blob/f

How are bugs "fixed in one place" that way? You either accept updates of third party packages, with little to no vetting of your own, and get fixes "for free" or… you don't. There's no middle ground: the only w

From a cursory look at your source code… It looks like memory is also not contiguous in your implementation. You don't support concurrency at all (xLock/xUnlock/xCheckReservedLock are noops). I'm not sure how APSW handle

Recent SQLite builds include the memdb [1] VFS (and the associated sqlite3_serialize and sqlite3_deserialize APIs) by default. How does this compare? I'm also curious what use cases you had in mind. My SQLite wrapper reimplements the m

I created https://rethinkraw.com that hijacks Adobe DNG Converter to provide a very limited Camera RAW that can even run on Linux. Why? Because why not.

You use unsafe for that bit. Still less gross than DoltHub's take on it.

I used to do the same, without public IP from the VPS. I just used Cloudflare, and a Go package [1] to lock down access to anyone but Cloudflare (because at the time their tunnels required Argo). I now also use a VPS that's dirt cheap

Oh I wanted to implement a virtual table to do the same thing in Go (access a remote DB, with where clause push down). Will have a look at your code!

database/sql adds some overhead; in return, it gives you a connection pool, and tries not to have you worry about connections. A lot of the interesting features of SQLite are connection oriented, and compared to other databases, co

Oh, great! I assumed you meant the officially supported System.Data.SQLite bindings. Do you have a link or is this internal?

Issue one: someone else was employed professionally to develope those bindings for you. :) Once that's done correctly and at a high quality, your life is easier. Developing those bindings is another story. But PInvoke is one of the bes

You need a virtual table (same as sqlite-vss) and a library that does cosine similarity indexing (Faiss here)… which I know little about. My plan was to evaluate Go for cosine similarity indexing, and if I found something promising, port th
