The AVX-512 story is just insane. I can't even begin to imagine the kind of corporate dysfunction that leads to, first, at long last introducing the biggest change in the instruction set since the Haswell era into the consumer CPU line
32.
by keldaris 5y ago
So, they're effectively killing off AVX-512 in the consumer space before it even really caught on. Makes me wonder whether AMD will bother with it at all. Either way, given the QoL improvements that were in the instruction set, this is

That varies by country and sometimes even by university. In some universities there are far fewer teaching positions than staff scientist jobs, particularly when you count research institutes, while in others a typical teaching load without

I'm a theoretical physicist. UBI would absolutely free me and most of my colleagues from grant writing (and IT freelancing, which frankly has better ROI at this point). I do basically all of my research on a mildly high end home comput

Except people do in fact ship large C projects all the time. The productivity gain associated with moving from assembly to C is undisputed and vastly exceeds any alleged productivity gain associated with moving from C to modern C++. Pretend

There is no way to use the STL and other template code and still have reasonably sized projects do full builds in seconds. That's just an empirical fact. The only way to get C-like compile times is to essentially write C, with minor ad

In my experience, you can just do full from-scratch builds in under 10 seconds for any sanely sized codebase (say, under 1M LoC conservatively). This obviously assumes the "orthodox C++" part, so YMMV wildly depending on how far y

The same is also true of the author's previous engine [1], written in C99. Would love to get the author's take on the costs and benefits of switching to Rust on the basis of what's effectively a reasonably sized real world ca

That's a completely fair point, but very subjective. There are lots of people (myself included) who feel exactly the opposite way.

The E14 also has a proper Thinkpad keyboard (or the best you can still get, at least). The difference is profound.

Could you elaborate in more detail? Given your wife's background, I'd guess you were referring to people with pre-existing hyperparathyroidism who are therefore prone to quickly develop hypercalcaemia from even modest Vitamin D su

Although the issue is complex, a very dominant part of the "some reason" was that the German army never really experienced an unequivocal final military defeat (although it was clear to the high command that the war could no longe

There is plenty of proof of long term and potentially permanent side effects, including some that are uncorrelated to disease severity. It's also true the relative prevalence of such side effects is far from well understood, but that i

Technically, I'm in a slightly similar position to yours as I had an uncommonly annoying respiratory infection during the last week of February (I am not in a disease epicenter, however, so my Bayesian prior is much weaker). I don&#x27

What would knowing for sure change for you? As you correctly noted, antibody levels seem to decline fairly quickly, so it's not like you can rely on immunity. It's true that there's a long and growing list of complications as

I deliberately made no comment on the necessity of wearing the respirator in the first place - that's a separate question. I'm simply saying that if you're going to the trouble of actually wearing a respirator, do it properly

Yes, that's why I'd love to get an antibody test right at the end of the isolation period. If that's impossible, that might be a reason to do the RT-qPCR test, but in that case it's probably still optimal to do the test

by keldaris 6y ago
I'm not sure I would volunteer myself because, really, what information is the test going to give you? If you test negative, the instructions are still to self isolate (and rightly so, obviously). If you test positive, there's no

This is probably a reasonable point in a subset (and mindset, frankly) of C++ that has very little overlap with the subset of C++ I use. Every C++ codebase I work on has RTTI (and exceptions) disabled immediately, so dynamic_cast isn't

Yeah, this is why I emphasized that these are prescriptions tailored to my personal usecases and style, not something that's supposed to work for everyone. I don't do anything remotely Java-related, so I have no opinion on your JN

That's true, but there's a reason I chose not to list it - this has never actually saved me from a bug, ever. Of course, as I said, your mileage may vary.

I'm sure this will be controversial, but my attitude towards C++ type casting is much, much simpler. 1. I only use static_cast, the other three C++-specific casts are, in my opinion, somewhere between useless and harmful. 2. The only m

It's a reference to [1] and a mindset arguably most common in the gamedev world that emphasizes simplicity, pragmatism and performance (including compile time performance) over many aspects of "modern C++". I've found it
