Over the last 10 years, I’ve learned something: Every single person claiming that “Python is slow” tends to be a newcomer with no experience building software. They are usually dropouts of a bad JavaScript bootcamp. More importantly, if you think that Python isn’t a

@svpino @Yampeleg I came from C++ and I say that python is slow and your post is fucking retarded.

@pilpulon @Yampeleg And you are a fucking racist.

@svpino Python is slow. Doesn't mean you can't build your applications.

@svpino Id like to see you write an OS in Python and see how well it performs compared to literally any other language

@svpino Python is the slowest language and it's not even close. https://benjdd.com/languages/

@svpino I’ve never found it to be the case. But shitting on JavaScript boot camps doesn’t help either. Many people including myself went that route……it’s how I actually landed my first gig…..ironically at a python based company. Python is my go to backend language for most of my

@svpino I’ve been a Python developer for over twenty years (I remember the Python 2 transition). For more then half that time I was principally a Python dev. Python is very slow. Almost anything else is faster. But most apps get hardly any traffic, if you have single digit requests per

@svpino Python is definitely slow. In order to speed it up, you have to use C++ libraries to handle the heavy lifting and then just have Python spit out the output. As a Computer Scientist and a teacher of AI/ML Engineering, you of all people should know this detail.

@svpino Tell me you don’t know about software engineering without telling me you don’t know about software engineering -an actual software engineer

@svpino There is amazing software built in Java and Python handling actual big data from Meta, Google and Amazon. People who blame the language for their software being slow are usually not good engineers. However, there are a few cases where you do need lower level languages

@svpino Python IS slow and you know it. This is you trolling for views, but I will indulge you. The GIL makes it slower even than the other single thread interpreted langauges (php and javascript). Can it be used in production ? Sure it can, and there are places where it does shine -

@svpino this discourse is hilarious cause when people say "python is not production ready" they mean, not production ready in my environment. but your environment is not everything, so this is honestly just blablabla. when we wanted to build a media system for our media monitoring

@svpino And yes its fukin slow your statement proves it. You may have been using it 20 years now but that’s the point you are used to it being slow. People came after you has learnt better with better option they have choice of whatever else they want.

@svpino I’m ~20 years into my career and have deployed production python apps at Amazon. It’s slow. It’s a development nightmare. It doesn’t scale. It ends up taking longer to deploy large enterprise apps. Typescript- if development speed is your priority. Rust - if efficiency and

@svpino @grok is this true?

@svpino I do not see a counter argument that says how incorrect this argument is. For loop is objectively slow, there isn't much to disagree here. Python still uses GIL, after 20+ years, still single core. Bro, what are we talkig here? Python is terrible, that is a fact.

@svpino So according to you a new comer can’t have an opinion now, and also saying that they are bad dropouts!! Bro you sound hurt. Its ok just a frekin language calm down man. 99% people can say its slow doesn’t matter if you like it then use it what are you getting all salty about!!!

@svpino Under the hood: - Pytorch: C++ - Tensorflow: C++ - LightGBM: C++ - Scipy: C/C++ As I said, if you use Python in production, usually "under the hood is other faster languages"

@svpino And it’s certainly not slow (relatively) as soon as you put an LLM call in the middle of your workflow.

@svpino Who cares if a language is slow? IDGAF if my employers slop runs 100ms slower than it would if I had to use a much more tedious language to make the backend.

@svpino Well it's a matter of what you're doing? High-throughout services where minor lag hurts the user experience? Yeah, it matters. Use something fast. MVP, internal admin tool (low concurrent users, some lag acceptable), basic crud operations? Don't over think it. Just use python or

@svpino Lots of the best stuff made with Python tend to use C/C++ libraries and Cython. It's an interesting wrapper language, I'll give you that much. I use it mostly for managing my bash scripts and the simplest AI tools.

@svpino Really now; I think that statement is invalid and Python is pathetically slow. It is like Heroin. Feels good at first but then the pain shows up. As a C programmer I will only do Python at Gunpoint.

@svpino Python is slow af. In fact, if it wasn't for data transformations or ML and how much stuff is already there for that ecosystem, it shouldn't be used for anything standard like CRUD APIs. All and all, it doesn't matter that is slow, in the grand scheme of things, but it is.

@svpino Python may be slow, but it’s the same with Ruby (my language of choice). Thankfully CPUs are fast. I’d rather optimise for getting more meaningful work done, and spend less time worrying about micro optimisations that make no difference to end users.

@svpino Doesn’t it all depend on what you’re comparing it to? These (disparaging) remarks are just as unmoored as theirs.

@svpino Python is slow, but that doesn't matter since your app will have no more than five users, 3 of them are your teammates.Atleast It's quick to build with Python.

@svpino Every idiot who's saying python is not used in production grade projects 1. Instagram runs the world’s largest Django deployment 2. Dropbox’s desktop client relies on over one million lines of Python

@svpino Python is SLOOOW. Now you have heard it from a 30+ years veteran. Have an embedded heterogeneous multiprocessor SOC running ARM/Linux on one set and a hard RTOS on Cortex M4 cores. System was controlled via Python and web UI. PC/cell app with RESTful interface to Python control

@svpino Python will never escape the feeling of being a kid's language in my mind. The only reason it got this far is because we have engineers who got their start with it in 06 when they googled 'easy programming languages'

@svpino It’s probably because have 0 clue that python is the backbone of ML, which is the backbone of the tool they wake up and go to sleep to.
