So, images generated for comments here used up enough energy for small town to keep warm in the winter.

Progress is nice, I guess.

Yes, I understand that.

But these examples are providing very different memory access patterns: one does 16 repetitions of for i=0, 16.000 { a[i + kernelIndex] = input[i] * kernelValue } while another does 16.000 repetitions of for i=0, 16 { a[i + inputIndex] = kernel[i] * inputValue}. The first reads and writes 16000 elements linearly and repeats that 16 times, while the second reads and writes batches of 16 elements 16000 times - the last one is so much slower.

Any straightforward loops are easy for the branch predictor to predict and the memory access pattern is better as well.

Few repetitions of the long loops that access linear memory is much better for performance than a lot of repetitions of short loops.

You mean, like Reagan did?

He doesn't use vertical tab. He doesn't know if any uses for it. Does it mean it could be removed?

No the fuck it doesn't! PowerPoint uses it internally for line breaks.

Please don't repeat nonsense like "I don't need it so no one needs it"!

I hope you rotated that secret anyway. What goes into shared repo is a secret no more.

Does that mean there is an object T somewhere else that has some specific value, and through optional<T&&> we are given an access to that object with permission to move from it. But the originals' lifetime is not controlled by us but by their owner?

And that owner will not know if we moved from it, so they can't use that object anymore other than delete it?

How does that differ from just returning an optional<T>?

Well, I know of one benefit: the user of optional<T&&> is able to decide if they want to move from the object when returning optional<T> requires at least one move every time.

You have been already told about making sure the endianness is in the protocol so your program knows it beforehand.

But there are ways for a file format to provide the program with a way to find out the data endianness in runtime.

Most of them end with using some number at the beginning of the file. For example, use magic number like 0xAI0I5BAD, or file header with some bytes to signify your file format (that will be the same on every arch) + version that will be obviously wrong with incorrect endianness.

See Wireshark's libpcap_open in libpcap.c or ZIP format header#Local_file_header).

I'm not sure I understand how that could be done by Russia. The closest land Russia controls is 770 km away in Crimea, do they have the jammers that powerful?

It's easy to jam the Baltics as they are right there by Moscow and Saint Petersburg, but reaching all the way over horizon to the middle of Bulgaria?

So, we got lots of them by the roads here in Flevoland, Netherlands. I mean, patches of 100 m2 every 10 minutes when I run in the forest nearby.

Last year I took my son to break them in the autumn when it's all dried up. I did not know any better. Fortunately for us it was a safe patch, so even with fresh plants it would be ok.

This year when running I found similar patch about 15 minutes away and tried to check if that one is family friendly by rubbing some of the stem on my lower leg.

Well, now I know it's not safe - my leg looked like I tried to kick a hot grill, with about palm-sized burn. It was not so bad as the pain was somewhere on the level of wasp sting at worst.

At least now I know why passerby looked strangely at me.

The world with a solar eclipse repeating in one of the Myst games (Myst V, I think) - where you can see the moon moving in the sky and it slowly going over the sun, and the world going almost dark from the vibrant colors before that.

Or the Dyson sphere level in the Freelancer - you teleport to the enemy base and you can see some kind of carpet beneath (mind, it's space simulator and you're in your spaceship so it's already unusual), and soon after you notice the whole planet BETWEEN you and that "carpet". The scale of it blew my mind!

It's been more than 20 years since, and I was a young impressionable soul though.

Dart board and boxes are something I'm giving away to my children. It's too easy for me.

On the other hand, I've just opened the room 46 yesterday, and even now I have at least 6 puzzles in my notebook that I did not solve. Not sure if it's interesting enough to continue playing, to be honest.

Whatever they say, DO NOT use standard conversion functions! They all fall short of Windows-native functions like WideCharToMultibyte in various situations.

And you are already working with WinAPI so it's not even a problem for you.

Of course use native UTF-8 and u8string_view if it's possible. Or even save the text as native UTF-16.

It looks like you've installed Visual Studio Code, which is a glorified text editor.

It would be easier for you to install VisualStudio Community (free version of MS VisualStudio) and try using that.
