Thanks, I appreciate it!

Makefiles operate at a low level of abstraction. The Makefile abstraction is "run this command when the output files don't exist or are older than the input files." You manually specify every tool to be run and all of its a

memcpy() by itself cannot violate aliasing rules. By definition, char can alias any object. Whether you can access an object that has been memcpy()'d into is a separate question. I can't find specific language about this, but I s

The unstated assumption that these figures are per server was not obvious to me. Your assumptions about my motives are incorrect and inappropriate.

> It may sound obvious, but - optimizing your app to fulfill a request in 1/10 the time is like adding 9 servers to a cluster. Optimizing to 1/100 the time (reducing requests from say 1.5 sec to 15ms) is like adding 99 servers.

We will never know whether any of Trump's wrongdoing rises to the level necessary to convict, because the Senate decided not to call any witnesses or subpoena any documents.

I think Poplar and Aspen are particularly notorious for this. I just had to cut down a 50 foot Aspen in a small-ish backyard because it had started rotting and was becoming unsafe. No one warned us what was going to happen next. Within the

The rationale for censorship of Greenwald's article is unconvincing, as that rationale is contradicted even by other people who agree with the censorship. As the story is already running elsewhere, it is unconvincing that there is a pr

In this thread I am seeing both "this story is already running non-stop on Fox, there's no censorship", and "if the editors didn't censor this, it would poison the election, and that's too big of a risk."

I'm ok with an escape hatch. I'm even ok with a strong convention. My primary concern is that there is a clear contractual line between "reading/writing this is supported" and "you're on your own."

Very interesting set of observations. As a C and C++ programmer, I am feeling more and more excited about Zig. One thing that feels missing from Zig though is encapsulation. I don't believe that you can declare struct fields private, s

If the data could be used against you, you should also have access to the data so it could be used to support your case. When there is asymmetric access to data, it's inherently unfair because the side with greater access will cherry-p

Sure, if you use less GC, then the penalties of GC are minimized. But that just reinforces the point that GC has a real cost. When you use less GC, you increase performance, but you also get fewer of the safety and convenience benefits of

Maybe I should! I didn't know about the Pimax 8K. Will all of these have access to the same software titles, or are they built on closed or incompatible software ecosystems?

As someone who only barely follows VR, what benefits would this have over the upcoming HP Reverb G2 besides price? I was eying the HP Reverb G2 for high resolution, and for its Microsoft Flight Simulator support. EDIT: ah I just found this:

That's great, I'll look forward to seeing the arena-oriented code someday. :)

Ah, in that case it sounds like heterogenous arenas are more or less a solved problem in Rust, even if they aren't necessarily 100% optimal. Probably the more difficult piece then is just how to model arena ownership of a tree of objec

I work on the protobuf team at Google, and I'm a big fan of Rust, though I haven't written much actual Rust except a bunch of Project Euler solutions. For protobuf in C++, we've been moving more and more in the direction of u
