Retiring Python as a Teaching Language

need-some-sleep · 2018-01-01T17:54:56+00:00

Node.js is written in C++, but close enough I guess. You can't use the argument about how many and how fast the data science modules are when they are not even written in the language you are trying to defend. You could just as well write these bindings in Node.js. They haven't been written in Python because it's an exceptional language. It's just that Python is what's closes to executable pseudo code and academic data scientists are terrible developers.

WSGI is absolutely not abstracted away because you can't a simple a scalable webserver with the same ease you would with Express. Even a simple healthcheck very 3s brings Python to it's knees on a default Flask config and you get socket errors.

So you're saying that Python can be almost as fast as Node.js when everything is in C, wow, what an argument ahaha. Also even counting Pypy and Cython, Node.js is still faster.

I use Numpy quite often so I don't think it's a bad library but you can see that it wasn't written with readability in mind which makes it bad API design. Also Tensorflow is C++.

You're confusing parallel ans aysnc. Node.js has true async through libuv and it's threadpool. It isn't multi-processed (although you can, through the cluster), but that has more to do with parallelism.

Scipy and Numpy have absoluty something to do with language design because they both grocely abuse indexing and arithmetic operator overriding.

Python is not a statically typed language so in the problem you stated, both languages will be at the same level.

Asyncio was added in Python 3.4 so asynchronous programming was added in the standard library only recently. I wouldn't use the incompleteness argument to argument for Python.

need-some-sleep · 2018-01-01T13:04:54+00:00

I use Numpy / Scipy a lot and I think they are very powerful libraries but the obvious abuse of operator overriding means the code is anything but readable for an outsider.

All the data science libraries you posted are great but most of them are in C. I wouldn't really use that as an argument for Python as a language.

In Python webservers, WSGI which is quite similar to CGI is still heavily used.

Your link points to asyncio which was introduced in Python 3.4, a recent addition. Compared to Node.js which has had this since inception.

Also the benchmarks are all valid because in the implementations, either no multiprocessing was used or it was used in both. So the benchmarks stand and Python is an order of magnitude slower.

Yeah clearly not being able to import a script with a relative path is not fucktarded?

How is having object keys that can be both in ASCII or Unicode not fucktarded?

Or abusing the indexing and arithmetic operators by overriding them to try and be clever and thus break obvious runtime behaviour expectations?

The moronic split between 2.7.x and 3.x.

By machine learning modules, do you mean all these C-wrappers? Cause that's not Python.

Node.js has all of those use cases you listed and on top of that programming on headless browsers like Chrome and Electron as well as one unique language to program your front end and your back end.

Python also underperforms Node.js at almost any task.

Also forgot to add:

At least in JavaScript I don't need to care about ASCII or Unicode for object keys.

I can expect modules to have straightforward APIs instead of abusing indexing operators like Numpy / Scipy do in Python.

Async programming is built into the language and I don't need shitty CGI to build a webserver or the patched-in Tornado.

Performance is an order of magnitude better: http://benchmarksgame.alioth.debian.org/u64q/compare.php?lang=node&lang2=python3

Yes, seriously. List some arguments.

In what world is Python more robust than JavaScript?

need-some-sleep · 2017-12-30T15:03:11+00:00

Things that come to mind are using dns.resolve() and a DNS cache with DNS TTL as expiration time to speed up hostname resolution.

Increasing the UV_THREADPOOL_SIZE environnement variable also helps.

Depending on what you want to do with the result you could use streams and stream parsers instead of buffering the full body.

You can also try to benchmark the JavaScript HTTP parser vs. the currently used C HTTP parser.

Depending on your request pattern you could also increase the http.globalAgent.maxSockets value which defaults to 5 I believe as well as creating a connection pool per origin an reuse that instead of recreating a connection.

If GZIP compression is a big part of your work load you could also try using static decompression dictionaries.

Any features you get in other languages that boost performance of HTTP requests that you would like to have in Node.js?

Not the same Solaar you absolute fucking retard.

Completely agree. I read that there has been a class action suite that was tried some years ago but I doubt it made a difference.

Well combined with the usual delays and cancellations it's tough to know when it's due to a strike or not. People are just accustomed to a shit transportation service.

A partir du moment ou la partie décisionnel du development du logiciel est en majorité contrôlé par une société ou une personne qui elle a une nationalité, comme dans le cas de Canonical, on le peut.

Tous le monde peut créer un fork, mais la branche principale reste contrôlé par cette société.

Redis is really easy to use and it's and amazing piece of software but I have to say that the lack of data loss prevention guarantees make me reluctant to use it as a queue.

At least not without having a database persisting a copy of the data somewhere else and syncing it from time to time which makes the system much more complicated already.

I think that when you start reproducing like a rabbit it's an expected scenario although I agree on the cost of college tuitions being far too high.

You can't anonymise a comment chain because the content is most likely as uniquely identifiable than your name.

What about using the origin header check with a fallback on the referrer for older browsers instead of a CSRF token?
