A seasoned programmer's take on Nim's docs

Was thinking I should perhaps clarify even more. Informally, we know that, AES run in CTR mode is provably secure (which we can formally define). Security proofs come with assumptions / requirements, and here, we have a few that are mostly reasonable to achieve. The major assumptions include: Th

Question about async programming

Thank you all. I'll leave it as is. For a pet language, I want to add all features I like in other languages, plus more :-P For the multithread support, I'm creating new VM for each thread, and use channels to communicate. Will see how it evolves as I add more use cases.

A seasoned programmer's take on Nim's docs

You are all missing the point of my benchmark, which was to get at the speed the raw ALGORITHM goes. It is SIMPLY one AES encrypt per 16 bytes of output. My approach was a back-of-the-napkin to show what my crappy machine does when there's very little overhead EXCEPT the encryption operation. B

BTW, another reason I used DD is because I didn't want to risk a smart enough compiler that knows reading/writing to /dev/zero is a noop optimizing it away, which would always end up over-reporting its performance :)

A seasoned programmer's take on Nim's docs

Good point, but I saw no perf diff between urandom & random on my boxes, both 550 MB/s. The bigger diff for me was from 35+ GB/s for /dev/zero.

Question about async programming

> Is this something I need to worry? Or is this part of async programming and > we all must live with? You must live with it as far as I can tell. For a "pet" language I wouldn't add async. ;-) Just make the interpreter re-entrant instead and build some of our nice multi-threaded server softwar

> I get /dev/random being 70+X slower, not ~2X slower It's not said about which device is meant, but it's probably /dev/urandom - from similar conversation on discord, and the manpage: > The /dev/random device is a legacy interface which dates back to a time where > the cryptographic primitives

Question about async programming

I am far from an expert on this, but my understanding of nim and python async runtimes, is that task switches (check for pending future, etc) _only_ happen when the routine that is currently running invokes `await` (or finishes). `await` explicitly pauses your routine and gives the control back

I mostly agree with all @pietroppeter said in this thread...but I tried to reproduce the AMD Linux `dd` benchmark justifying this > It's only about twice as fast. [..] Frankly, the performance difference is > such a non-issue that I would nuke existing statistical PRNGs all together. and notice

Question about async programming

Hi, I added async support to my pet language and after reading more about async programming, I have some questions. Currently, in my interpreter, after every X evaluations, the interpreter will check whether there are pending futures and if yes, check their states, call the success or failure

Two type matches, both wrong: how to do it right?

`distinct` in the parameter list means something entirely different. Don't use it. ;-)

Regex error - "Error: missing closing ' for character literal"

Really cool work!

Two type matches, both wrong: how to do it right?

xigoi, yes, that is how I am now thinking of it. I'll use it when it makes sense. What I was hoping for was something like: proc `$`*(bb: distinct Bitboard): string = ... Run working and meaning the type is distinct for that function, but I understand that kind of thi

Is there a way to print the documents without printing the rest of the html?

I printed one document and I can't read it, because the text is too small. Another suggestion would be to set the print margins on the left and right side way smaller and the third would be that there is a lot of white space between the chapters.

Nim v2: what would you change?

What's wrong with indentation? Things like `end` just add unnecessary syntactic noise that you need to filter out and it decreases the amount of code you can see at once.

Two type matches, both wrong: how to do it right?

You can think of a distinct type as an object type with one field.

you mean avaiable? or something need to be implemented , the stable document will update when release next version I guess.

Is there a way to print the documents without printing the rest of the html?

That is very good! I was about to put a "print" button on top but when I print it is already the document. Good work!

Array concatenation

One can also use the `@` operator: let a = [1, 2, 3, 4] let b = [5, 6] echo @a & @b Run
