Instead of focusing on bytes.Reader, the author could maybe propose that bytes.Buffer (which already has a Bytes method) implements Peek as well. bytes.Buffer already has many methods exposing the internal buffer, so one more is not insurmo

It's as good an opportunity as any to improve things. They're acting as selfish demanding you do something for them, as you are for refusing.

Then you want the Dacia Media Control. It has a phone holder where other trim levels would place the screen, and USB power around there. Other than that, the car is mostly Bluetooth a speaker. They actually have an app that allows you to tu

As an “insignificant” outside contributor to Go (I think I worked on half a dozen proposals and PRs), I can say just the same, even for things that in the end got dropped or rejected: polite, firm, informative; I'd add curious. Had a g

They were sufficient for me to implement most of `string.h` and get speedups between 4 and 16x vs “portable musl C code,” including sophisticated algorithms such as this one: http://0x80.pl/notesen/2016-11-28-simd-strfi

We (at least I) compensate for that by having 10k photos on it, which again makes it impossible to find anything. And if you decide to cull them because it's just too much, it's a chore.

The hashing algorithm is specified in the docs: s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1] Per Hyrum's law, there's no changing it now. https://docs.oracle.com/javase/8/docs/api/java&#

Sure. Portugal is in deed completely “isolated” if it loses Spain, so it needs black start capability if it wants some degree of autonomy. As far as containing the issue, this was a disaster. On the flip side, this was as good an opport

I'm open to adding it to my driver, if people consider it essential. Every extra bit makes AOT compiling the Wasm slower (impacting startup time). I also wanna keep the number of variants reasonable, or my repo blows up. Add your votes

People reply to the “Good morning Vietnam” post with “OK, so the plan is working” and “you'll do in 60 days what you tried to do for a year.” Who are these people?

Even then, the interconnect capacity with France is currently 2800 MW (was 1400 MW in 2015) with just 3 links, all on the NE. If Portugal (on the West) had to wait for that, it would probably have taken even longer.

I expect those two (one CCNG, one hydro) are the protocol for a black start, but other hydros should have the capability should those fail.

But each SQLite connection (even to the same DB) will also consume 2 FDs for the DB and the WAL. You'll more easily pool connections to the same DB, of course, but the difference might not be so stark.

Looking at the diagram for the SQLite VFS page I didn't think I was going overboard with designing my driver around 3 packages: https://sqlite.org/vfs.html One layer wraps SQLite C API, below it lives a pure Go VFS, an

But, don't you know you can't have a utils package either? A package must implement one functionality, and it must be clear from the short import name what that functionality is. A package is also the only way to enforce visibilit

Of course Go has warnings. It has go vet, which is not a linter, and according to the authors doesn't need comments to ignore checks, because the checks are always correct about you having written shitty code. Except where it might war

I'm not that great at long form writing to be honest, it's always a bit of a chore, and I'm never happy with the result. To answer your question, it needs a libc because you're including stdlib.h, and exporting and allo

A PR is a significant investment from me. I'd have to figure out where something like this is supposed to fit, how the build infra works, etc. One of the nice things about Go is how much that's a solved issue out of the box, compa

As far as Go is concerned, the Wasm sandbox makes the (addressable, C) stack explicit, which solves at least some of the issues CGO has to deal with. It's not a panacea, though; it introduces other issues.

by ncruces 2y ago
Yeah, so far I did exactly the ones (my build of) SQLite needed and not others. If there's interest, the set of implemented functions can definitely be extended.

I'd like to be a little more sure that I'm not totally messing things up before doing that, but yes, eventually, that would be a nice outcome. I've also only really tested wazero. I can't know for sure that this is a
