Plenty of high refresh gaming monitors out there that use HDMI 2.1 or DP1.4 with DSC. DSC is just the "card up the sleeve" for DP1.4, you can push it all the way to 4K 240hz HDR. So there is little incentive to switch to DP2.1 for

Oh yeah, I've read about all your blog post on this topic :) To dump some ideas on you: I think one missing piece might be that FnOnce() -> impl Future should implement IntoFuture. Async runtimes would then use IntoFuture in their A

by Dagonfly 1mo ago
Sure, thats one reason why IntoFuture and Future exist. Imo, in hindsight this is also main mistake in aysnc Rust: The whole async system should be build around IntoFuture rather than Future (async fn should return impl IntoFuture). That wa

The compat issue has always been associated types on std traits. For example, should Iterator::Item be Move or ?Move If you leave it as Move, you can't create any iterators over !Move types. If you change it to ?Move, then functions us

Passing ownership to another thread is not the same as forgetting/leaking. The point of !Forget is ensuring that once the owner goes out of scope the destructor must be guaranteed to run. An infinite loop is not a problem, cause the ne

It's the one thing I miss from Swift when I'm using literally any other language. Interal and external parameter names. I would love for Rust to adopt: fn foo(namedParam internalName: bool) { // use internalName here

You are right that intraday went even more negative than day-ahead. But I disagree about the rest of your comment. A spread between day-ahead and intraday does not imply additional redispatch. Only some of it might have been countertrading

So many questionable comments in here. Negative prices have no effect on grid stability. It just means that the day-ahead market was cleared below 0, i.e. for every consumer (buyer) there is a producer (seller) selling at this price. The ma

For DP adoption it's too late. They should push for USB4 / Thunderbolt 4 instead. We are in the phase where about every new laptop has USB4. Connecting your laptop/phone to a TV might be a selling point. I'd love that fo

Yes, HDCP is seperate from HDMI and DP. The source and the sink need a HDCP-licence. Both devices have embbed keys that get exchanged to estabish a encrypted channel. Without the licence you can't get the required key material. AFAIK,

All of those are i586 or i686 though right? AMD Geode LX is the only i586 CPU produced in the last 15 years. Everything else is at least i686 and Rust has perfectly adequate i686 support. Is there any major distro left with pre i686 suppor

I'm also surprised how often the preemptive vs. cooperative angle gets ignored in favor of the stackful vs stackless debate. If you choose a non-preemptive system, you naturally need yield points for cooperation. Those can either be ex

That's true. Though, for my example, the storage location of the array metadata/fat pointer is not relevant. In Rust you can hold references directly into the buffer backing the array (`&v[0]`). My Java knowledge is quite rust

You could pose the same argument against any form of warranty. Why provide/require any warrant for anything if the company might go bankrupt? Yeah, then it gets messy. That's what the legal system and insolvency procedures are for

Assume your cycle detection D(TM, i) always outputs 1 when TM(i) doesn't halt (TM is the encoding of a turing machine and i is the input to TM). Otherwise, if TM(i) halts, D does NOT halt. [1] We can construct a new turing machine F(TM

As most of the kernel is in C, they probably need a raw pointer quite regularly to pass it into existing C APIs. Just like `Box::into_raw`, this method shouldn't be used in pure Rust code. It's only available for C FFI.

Nitpick: There are actually a handful Rust drivers in-tree, e.g. https://github.com/torvalds/linux/blob/master/drivers/net/ph... Though, I think all of them are direct ports of existing drivers
