Given that your examples of using std::cout are using the wrong I/O direction, I am surprised you have "25 years experience of c++". Perhaps, that annoyed him too. Still, yelling doesn't help much of anything. Edit: OP

Yeah, sounds like it's possible but an unreasonably high burden (imo).

I hope it's not too off topic. But on Linux systems with NVIDIA drivers - is it even possible/reasonable to re-enable secure boot?

Perhaps the terminal is linebuffered. (edit: I forgot that `!` was a character in Rust, so I mis-read your comment, oh well).

When doing geometry, it is common to pass around double[3] or double[3][3] types.

I have interviewed a lot of developers, and floating point precision is one of my common phone screen questions. My experience is; those who should know about it, do. Of course, a lot of apps or web developers don't. And I think th

Your understanding is correct.

`printf` implements a barrier which cannot be crossed by an optimizer.

I have known founders with 0 experience hack together god awful C++ programs that ran their business long enough for them to fund competent programmers. Never underestimate the value of a persistent person!

The scam was not by all btc pioneers. In the last year, there were a lot of holders creating marketing networks filled with misinformation and half-truths. That convinced a lot of people with little financial education and little unders

I am probably one of the few who has gone the other way. I had a Facebook when it was college e-mail only. I got rid of it... and then I added it back this year. It turns out that Facebook is fundamentally required if you want to schedule

I understand what you are saying, and I agree that it's true in principle. But, if C++ did not provide me predictable optimizations - it would be worthless to me. I know scientific computing is only one domain of computing. But witho

Is the C++ standards committee trying to make the language as incomprehensible to its users as possible? I cannot even begin to comprehend what assembly is going to be generated in this code sample. Are those calls indirect? Can they be v

I think the market has decided, America is going green independent of federal regulations. Oil independence means the US will never again need to ally with despots to support domestic needs. IMO this is a huge step forward.

That must be a very betraying experience, I am sorry you had to go through it.

And fwiw I have had quite a few Android phones; including Google's Pixel2 and G2X. So far, this one seems to be the worst.

Pixel 3 is an expensive piece of crap. Call quality sucks, battery life is terrible. And the USB-C will for stretches fail to recognize the provided earphones as an audio device (it reports that it's charging them). There are somehow

What about the various RTOS people or embedded firmware people? Or the mathematicians... or the... It's like saying, "Let's get everyone who speaks English speakers together to agree on our favorite tea."

OpenCV is ubiquitous in some domains. It's like asking; "What's numpy?"

It sounds like you have not practiced discipline, it's not innate. Luckily life is the perfect teacher. Take up a hobby for purpose of being disciplined. For me it used to be weight lifting, then wood working, now music. Make a real

I am not often a Windows programmer, but I followed that saga. I think it was the result of poor internal communication and was fairly anomalous for Microsoft.

As long as you are fine with companies tracking every place you go (via GPS), everything you purchase, everything you view on line, and everybody you know. Then sure, the phone can replace cash. Often I do not want any record that I have p

Thank you so much for sharing this, I did not know. I guess I will have to look for the version GCC version which supported X86_64.. I might have to upgrade distros for GCC6 (older versions were i386). Btw, this was a nice presentation of

Yes, SIMD intrinsic programming is often worthless unless implemented for every target architecture. Let me give you an example case; my target production architecture rarely changes, but I want my program to run on every developer compute

Yeah, btw I think I cited quarterly. Still I think the multiple is too high. I understand 15x for a private company and 10x for a public. But in an inflated market, higher than that? If I had internet other than my phone I would look it

Yeah, your intuition seems correct to me. I wonder if I was thinking about 64 to 32 signed, or if just didn't know.

Approx $26 million of net profit fetched $2 billion in acquisition? A somewhere between 65 and 75x multiple? That doesn't seem right. Are my numbers wrong?
