Yes. They should not have included any adapter at all. Those with older PSUs should have had to make a decision about whether they want an adapter or not, and then pick an adapter of the appropiate quality.

TBH NVIDIA should just have not included any adapter at all.

by maxwell86 4y ago
Agreed, not sure what other words to use instead. I think it would have been better for these cards to not have an adapter at all. I've added an EDIT to try to word this differently.

Thanks. I've added an EDIT to clarify that I am not speculating about whether the OP read the article, and that the only point of my comment is to set the record straight for those who often just come to HN for the comments (like mysel

That's the opposite of all other traffic rules in the UK. Cars stop on the left, which allow other cars to overtake them on the right.

The Rust module system is radically different from C and C++ and other similar languages in the embedded space. Every build system that has added support for Rust, which aren't many, had to be radically modified to achieve that. None o

Rust already has a GCC backend that can do all that. This post is about a new front-end.

The rust compiler can already use GCC as a backend. So I don't see how this opens more platforms than that.

If you only write to the lower 32-bit of the v0 register, which could be 1024 bit wide, that claims that the hardware somehow has to allocate a 1024-bit wide register to back those up, and then makes some "locality" arguments. The

This is not really a problem. While it is true that you can only use masks from v0, and this requires moving masks into v0 after calling a vector instruction, those moves don't actually copy data from one register to another. Instead,

It's ok to like OpenMP. What I disagree with is that it should be suggested to beginners as the way to parallelize their C++ programs. That's like telling a Javascript programmer that they should parallelize their programs by usin

lol please no If you are using C++, and want to parallelize something, just add "std::execution::par" to your algorithms. Instead of writing "std::for_each(...)" just write "std::for_each(std::execution::par, ...)&q

You can’t drive in a German motorway at 110kph. You’d be in the truck lane at 80kph for your whole trip, having to over take every single truck, of which there are many. So 130kph+ is the minimum unless you are towing.
