Ok

Oliver

I do that, look in my bio. Beyond that you will need a quite solid understanding of C

Please teach me

Welcome!

How are you? Is there a question you want to understand?

Orange Juice

How are you? Is there a question you want to understand?

Yes, how do I print hello world in c programming?

CodeBy

Yes, how do I print hello world in c programming?

Just use printf command that's basic

Martha

Yes, how do I print hello world in c programming?

It depends on what u want to print on the console Basic-> printf

Gurpreet

Give me the video for loops in c++

Need to make an app to generate thousands of pdf files with data from a database and upload the result to an object storage. I have a dilemma: whether build it on python or on c++. What do you, guys, think?

I don't do python much, but if you can avoid data manipulation in python itself it should be sufficient

Vlad

If it requires processing it would really slow

Vlad

If it is gluing database and rendering lib together then it doesn't matter

Vlad

But if it's simple like that you probably should do it in C++ anyway if you can stomach it and not bitch and moan too hard

Vlad

Cause if requirements change you will have a leeway

Igor

Thanks

Igor

I’ll stick to python

Vlad

I’ll stick to python

If it gets slow you may rewrite some parts as a C module

Vlad

Given that the gluing itself is not a bottleneck

Vlad

Which it might be if it's a lot of data and you use a crappy orm

Vlad

If the performance and speed of generating is not important definitely python is the best choice

Dot

I don't think it will be that much slow to force him to use another language, while the libraries he is going to use are probably written in C or C ++.

Vlad

I don't think it will be that much slow to force him to use another language, while the libraries he is going to use are probably written in C or C ++.

If his orm gives him some shitty ass python dict as a result and then he needs to feed every record from it line by line into the lib it would really slow

Vlad

Also overhead on duplication, copying data over

Vlad

And he said that it would be thousands of files

Vlad

Also we don't know how slow his queries would be

Ludovic 'Archivist'

I am doing web development in C++, it is fun, except the web parts

Ludovic 'Archivist'

I don't want to do web design

Vlad

I am doing web development in C++, it is fun, except the web parts

I don't think web is ever fun

Ludovic 'Archivist'

But hey, I can serve 60000 request a second on 4 cores from 2011

Vlad

Cool but will there ever be at least 60000 users?

Ludovic 'Archivist'

Cool but will there ever be at least 60000 users?

of course no, but I don't plan to use 4 cores on the server

Dot

Also we don't know how slow his queries would be

True. But the reason for doing this is probably to archive, and that was my impression, and I don't think the execution speed is that important, otherwise if what you said is implemented, yes, it will be slow. But in the data field, Python is mostly used, so I think the language and library itself are optimized enough for this, and with a little optimization from the programmer himself, I don't think it will be a problem.

It's one of those things where you can hit exponential slowdown for no reason

Vlad

And one hour of archiving might become a week

Ludovic 'Archivist'

Quite similar to JS in the end, it's just middlewares and coroutines

If you were to build the project with JavaScript or .NET, how many users would you be able to handle?

Ludovic 'Archivist'

If you were to build the project with JavaScript or .NET, how many users would you be able to handle?

With dotnet, around 1/12 that

Ludovic 'Archivist'

already tested

Ludovic 'Archivist'

With JS, optimistically 85% of what dotnet would handle if I do not screw up the templating

Dot

And one hour of archiving might become a week

We hope this doesn't happen. If this happens, I can't imagine people working with Python Big Data.

Dot

already tested

1/12? You mean around 5000 users? This is a huge difference.

Vlad

We hope this doesn't happen. If this happens, I can't imagine people working with Python Big Data.

I can't imagine using python for anything but scripting, but here we are

Dot

May I ask what C++ framework and library you are using to complete the project?

Vlad

May I ask what C++ framework and library you are using to complete the project?

drogon probably

Ludovic 'Archivist'

1/12? You mean around 5000 users? This is a huge difference.

Yeah, dotnet is still pretty good, but it is not lean at all and wastes a lot of time in sync IO because of the design of the framework

Ludovic 'Archivist'

drogon probably

indeed

Ludovic 'Archivist'

I made my own web page generator, called it overreact as a mockery of the underwhelming other framework

Dot

I can't imagine using python for anything but scripting, but here we are

😂😂You can't imagine my face when I found out that the language used for the world's largest and most complex AI and data processing projects is Python. I felt a little better when I found out that the libraries used were written in C and C++, but only a little.

Ludovic 'Archivist'

Yeah, dotnet is still pretty good, but it is not lean at all and wastes a lot of time in sync IO because of the design of the framework

Also, my CPU is from a decade and a half ago, my L3 cache is just like 32MB and the dotnet framework does a lot of indirection, wreaks havoc in the cache usage with its sheer size too

Vlad

That's more of a C# shortcoming

Vlad

Since it's literally 'everything is a heap pointer' the lang

Thank you for sharing your experience. I have probably never seen such a detailed comparison between the performance of C++ and the top web languages. If you publish the web page generator you wrote on GitHub, we would be very happy if you could send us the link so we can follow along.

Umm I'm surprised .Net can only do this much, what app are you making?

Ludovic 'Archivist'

Umm I'm surprised .Net can only do this much, what app are you making?

Nothing too complicated really, mostly a website with a templating engine on top of it

Ludovic 'Archivist'

I am, like I said, pretty sure that cache evictions are the main slowdown for dotnet

Ludovic 'Archivist'

I will profile it against C++ and drogon when I have time

Vlad

Umm I'm surprised .Net can only do this much, what app are you making?

Probably the site is too light so it's kind of the worst case scenario for dotnet

Umm so like most websites, .Net should be able to handle more than that on 4 cores. On my 10th gen I5 laptop with 8 cores, .Net 9 can handle more than 200,000 req/s

Vlad

Usually it's for the sites where you're database bound and some heavy logic going on on the back end

Ludovic 'Archivist'

Umm so like most websites, .Net should be able to handle more than that on 4 cores. On my 10th gen I5 laptop with 8 cores, .Net 9 can handle more than 200,000 req/s

Static files or dynamically generated with localization from an in-memory hashmap?

Ludovic 'Archivist'

Yeah dotnet is very much OK for static files, it is on-par with C++ there

Ludovic 'Archivist'

Umm so like most websites, .Net should be able to handle more than that on 4 cores. On my 10th gen I5 laptop with 8 cores, .Net 9 can handle more than 200,000 req/s

Keep in mind my CPU is 2nd gen
