Java, Rust & Ruby have built-in support for concurrency. Maybe they are bidding on ads, or tagging posts with "likes" and so on. In that case maybe a cache in front of it will work just as well to speed things up. I am looking to start an experimental project using a functional language and am trying to decide beween Erlang and Haskell, and both have some points that I really like. My questions are about Web Apps and Elixir and scaling. If you're going to set pixel based margins on the left and right side of your page, you need a media query to disable it or at least lower it to 5 pixels on small screens. Erlang is historically bad at string processing, and it turns out that string processing is very frequently the limiting factor in networked systems because you have to serialize data every time you want to transfer it. In Python, it looks like he was using Celery with Redis then RabbitMQ. Tadaaa. We’re running it over at twistedmatrix.com for our primary DNS and we’ve had no problems. Scalability is as much about being able to think through your code as it is about systems-level optimizations. Saw on HN everyone is switching" -- cue years wasted in rewriting and destabilizing a solid usable code base. The most important reason people chose Python is: Python's popularity and beginner friendliness has led to a wealth of tutorials and example code on the internet. We get around this problem by launching one API server per core and load balancing with nginx. The only major (valid?) It was quick and easy for me to implement a clear and easy-to-use analog in Python, and I was able to enhance some of the backing algorithms in the process. The lack of centralized state might seem minor but unless you have been debugging a shared memory systems with locks, threads and manual memory allocations, with classes that have pages of attributes defined, and trying to understand why it crashes on Wednesdays only at customer A's site, it is easy to miss the benefit. > if you get far enough and need to scale. http://ruby-doc.org/core-2.2.0/Thread.html, http://ruby-doc.org/core-2.2.0/Fiber.html. I'm going to go out on a limb and say that performance is more subtle than can be reduced to a single "is better than" about throughput in HTTP requests or computing mandelbrot fractals in the shootout. Most stuff works nicely with net/http. The reason is the observation that the higher the concurrency or complexity in the system, the higher the need for fault tolerance. Time and again companies have rewritten systems from MVP to handle data safer, better, and faster, from Dropbox to Twitch to CloudFlare to Uber to Mail.ru... For the sake of discovering a middle ground between our arguments, let's look at an example of a >$1B company running Rails: Github. Not sure how deeply you want this explanation to go, so will stop here. With a single process, mind you, it was handling 4,863 messages per second for the 1,000,000 messages I ran. Again, thank you for your answer. The advantage there is the database is integrated into the langauge. I’ve written a few servers like this as personal projects, but I’ve never gotten the opportunity to throw one against real scale. And somewhat inspirational - maybe HN can become multi-lingual down the line through the equivalent of 'subreddits' or simply threads being marked as another language, with translate buttons available for those who don't speak the language. The problem you had seems to be, simply stated, that you didn’t have access to good erlang programmers. We'll end up in a best-of-both-worlds scenario. Go for what your team feels good with. >Python and Ruby get you where you need to be fast. This is understandable, given that Elixir is a functional programming language while Python is not. If you serve 1M connections and your backend segfaults, you get 1M phone calls. Native JSON handling has been an Erlang Extension Proposal for quite while now, who knows when it will happen though. Let's just assume we can mostly agree on that. Full access to Erlang functions. Files for python-erlang, version 0.2.2; Filename, size File type Python version Upload date Hashes; Filename, size python-erlang-0.2.2.macosx-10.5-x86_64.tar.gz (2.8 kB) File type Dumb Binary Python version any Upload date Nov 27, 2016 Hashes View I then wondered how much of that time was taken up by writing to the DB, so I removed that part of the test and re-ran it. Some subsystem crashes and restarts? Overall I agree that Erlang based frameworks are game changer. Everything was running on Rackspace. Python does feature some very basic pattern matching, but it pales in comparison to what is possible with Elixir. I don't program Erlang, but discovering communicating sequential processes for multithreading was a revelation to me. The longer you can preserve those ergonomics, the better. Of course, a major concern with Python is performance. Hard to give a general advice here. Changes That’ll Make a Big Difference With Your Learning Programming For Kids : Any Kid Can Code. I’m afraid this means you’d be losing most if not all of the benefits of using PyPy (especially if mixpanel uses libraries with excellent C extensions like psycopg2, simplejson, or Thrift). Viewed 20k times 29. Do you have the reference for the Python JSON library speed benchmarks? Python is to get small stuff done quickly language for me. If you need cache use it. Yes, the article was pretty badly written I thought. Oh and their's this thing call Erlang and it's fast! Can express ideas at a higher level. Not a fair comparison, IMHO. I think you’d be VERY pleased with its performance if you had stuck with it. We get around this problem by launching one API server per core and load balancing with nginx. The algorithm is beautifull in its simple recursion and may remind you of the "Tower of Hanoi", another project on this site. The same would happen in Ruby or C++ or YYY. I wouldn't switch my main tool to something with a specific usecase. And link other node to yours. But do you consider using celery or are you using celery [1] in some part of your application? With the help of sympy.stats.Erlang() method, we can get the continuous random variable representing the erlang distribution.. Syntax : sympy.stats.Erlang(name, k, l) Where, k is the positive integer and l is a real number greater than 0. It was mainly just complaints about Python than any real exploration of why Erlang was better. Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system.The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs. What is your experience with the performance differences between Python and Erlang? Tools & Services Compare Tools Search Browse Tool Alternatives Browse Tool Categories Submit A Tool Job Search Stories & Blog. Too many companies end up following this cargo-cult advice, and spend more time grappling with their tools than innovating. Honest question. In the case of Elixir, many feel that it adds some innovative language features like the pipe ("|>") operator and metaprogramming facilities that ease many of the pain points with Erlang. I've heard and seen cases of companies rewriting stuff unnecessarily due to some incompetent people following latest fads. > Erlang generated a lot of buzz several years ago but aside from the recent success of WhatsApp it never quite stuck. Erlang vs. Unintentionally Purely Functional Python. Yeah of course. The standard Erlang/OTP installation includes cover, a test coverage tool.

In this case, you probably first start by switching your message queuing to Erlang (RabbitMQ), since you had a problem with that anyway; then you can expand outwards from there if it makes sense or makes you happy: job running in Erlang, webservices in Erlang, putting the data in mnesia instead of postgres, etc. My guess is that Github uses a few more cpus than "a fistful of c4.larges" suggests. But Erlang is a the secret sauce (so to speak) for a high concurrency fault tolerant backend. That got me 6,700 messages per second. Yes, the asyncio library was introduced in Python 3.4. point you had on performance seemed to be based around a single implementation (mochijson) of a JSON library and more generally strings. The "scale", , the reciprocal of the rate, is sometimes used instead. > Java, Rust & Ruby have built-in support for concurrency. Maybe they are bidding on ads, or tagging posts with "likes" and so on. In that case maybe a cache in front of it will work just as well to speed things up. I am looking to start an experimental project using a functional language and am trying to decide beween Erlang and Haskell, and both have some points that I really like. My questions are about Web Apps and Elixir and scaling. If you're going to set pixel based margins on the left and right side of your page, you need a media query to disable it or at least lower it to 5 pixels on small screens. Erlang is historically bad at string processing, and it turns out that string processing is very frequently the limiting factor in networked systems because you have to serialize data every time you want to transfer it. In Python, it looks like he was using Celery with Redis then RabbitMQ. Tadaaa. We’re running it over at twistedmatrix.com for our primary DNS and we’ve had no problems. Scalability is as much about being able to think through your code as it is about systems-level optimizations. Saw on HN everyone is switching" -- cue years wasted in rewriting and destabilizing a solid usable code base. The most important reason people chose Python is: Python's popularity and beginner friendliness has led to a wealth of tutorials and example code on the internet. We get around this problem by launching one API server per core and load balancing with nginx. The only major (valid?) It was quick and easy for me to implement a clear and easy-to-use analog in Python, and I was able to enhance some of the backing algorithms in the process. The lack of centralized state might seem minor but unless you have been debugging a shared memory systems with locks, threads and manual memory allocations, with classes that have pages of attributes defined, and trying to understand why it crashes on Wednesdays only at customer A's site, it is easy to miss the benefit. > if you get far enough and need to scale. http://ruby-doc.org/core-2.2.0/Thread.html, http://ruby-doc.org/core-2.2.0/Fiber.html. I'm going to go out on a limb and say that performance is more subtle than can be reduced to a single "is better than" about throughput in HTTP requests or computing mandelbrot fractals in the shootout. Most stuff works nicely with net/http. The reason is the observation that the higher the concurrency or complexity in the system, the higher the need for fault tolerance. Time and again companies have rewritten systems from MVP to handle data safer, better, and faster, from Dropbox to Twitch to CloudFlare to Uber to Mail.ru... For the sake of discovering a middle ground between our arguments, let's look at an example of a >$1B company running Rails: Github. Not sure how deeply you want this explanation to go, so will stop here. With a single process, mind you, it was handling 4,863 messages per second for the 1,000,000 messages I ran. Again, thank you for your answer. The advantage there is the database is integrated into the langauge. I’ve written a few servers like this as personal projects, but I’ve never gotten the opportunity to throw one against real scale. And somewhat inspirational - maybe HN can become multi-lingual down the line through the equivalent of 'subreddits' or simply threads being marked as another language, with translate buttons available for those who don't speak the language. The problem you had seems to be, simply stated, that you didn’t have access to good erlang programmers. We'll end up in a best-of-both-worlds scenario. Go for what your team feels good with. >Python and Ruby get you where you need to be fast. This is understandable, given that Elixir is a functional programming language while Python is not. If you serve 1M connections and your backend segfaults, you get 1M phone calls. Native JSON handling has been an Erlang Extension Proposal for quite while now, who knows when it will happen though. Let's just assume we can mostly agree on that. Full access to Erlang functions. Files for python-erlang, version 0.2.2; Filename, size File type Python version Upload date Hashes; Filename, size python-erlang-0.2.2.macosx-10.5-x86_64.tar.gz (2.8 kB) File type Dumb Binary Python version any Upload date Nov 27, 2016 Hashes View I then wondered how much of that time was taken up by writing to the DB, so I removed that part of the test and re-ran it. Some subsystem crashes and restarts? Overall I agree that Erlang based frameworks are game changer. Everything was running on Rackspace. Python does feature some very basic pattern matching, but it pales in comparison to what is possible with Elixir. I don't program Erlang, but discovering communicating sequential processes for multithreading was a revelation to me. The longer you can preserve those ergonomics, the better. Of course, a major concern with Python is performance. Hard to give a general advice here. Changes That’ll Make a Big Difference With Your Learning Programming For Kids : Any Kid Can Code. I’m afraid this means you’d be losing most if not all of the benefits of using PyPy (especially if mixpanel uses libraries with excellent C extensions like psycopg2, simplejson, or Thrift). Viewed 20k times 29. Do you have the reference for the Python JSON library speed benchmarks? Python is to get small stuff done quickly language for me. If you need cache use it. Yes, the article was pretty badly written I thought. Oh and their's this thing call Erlang and it's fast! Can express ideas at a higher level. Not a fair comparison, IMHO. I think you’d be VERY pleased with its performance if you had stuck with it. We get around this problem by launching one API server per core and load balancing with nginx. The algorithm is beautifull in its simple recursion and may remind you of the "Tower of Hanoi", another project on this site. The same would happen in Ruby or C++ or YYY. I wouldn't switch my main tool to something with a specific usecase. And link other node to yours. But do you consider using celery or are you using celery [1] in some part of your application? With the help of sympy.stats.Erlang() method, we can get the continuous random variable representing the erlang distribution.. Syntax : sympy.stats.Erlang(name, k, l) Where, k is the positive integer and l is a real number greater than 0. It was mainly just complaints about Python than any real exploration of why Erlang was better. Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system.The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs. What is your experience with the performance differences between Python and Erlang? Tools & Services Compare Tools Search Browse Tool Alternatives Browse Tool Categories Submit A Tool Job Search Stories & Blog. Too many companies end up following this cargo-cult advice, and spend more time grappling with their tools than innovating. Honest question. In the case of Elixir, many feel that it adds some innovative language features like the pipe ("|>") operator and metaprogramming facilities that ease many of the pain points with Erlang. I've heard and seen cases of companies rewriting stuff unnecessarily due to some incompetent people following latest fads. > Erlang generated a lot of buzz several years ago but aside from the recent success of WhatsApp it never quite stuck. Erlang vs. Unintentionally Purely Functional Python. Yeah of course. The standard Erlang/OTP installation includes cover, a test coverage tool. The failure could be anything from invalid base-64 encoding to an error on our end. I don't think one is a superset of another.
