February 05, 2024 · 9 mins · 1675 words Share on: X · HN Discussion on HackerNews. Last September I hopped on board with Wallapop as a Search Data Scientist and since then part of my work has been working with Solr, an open-source search engine based on Lucene. I’ve got the basics of how a search engine works, but I had this itch to understand it even better. So, I rolled up my sleeves and decided
Python's "Type Hints" are a bit of a disappointment to me

I've incorporated some feedback I got into this revised version. Introduction Over the course of several Python 3.x versions, "type hints" were introduced. You can now annotate functions: def greeting(name: str) -> str: return 'Hello '
Python behind the scenes #13: the GIL and its effects on Python multithreading
As you probably know, the GIL stands for the Global Interpreter Lock, and its job is to make the CPython interpreter thread-safe. The GIL allows only one OS thread to execute Python bytecode at any given time, and the consequence of this is that it's not possible to speed up CPU-intensive Python code by distributing the work among multiple threads. This is, however, not the only negative effect of

Python behind the scenes #11: how the Python import system works
If you ask me to name the most misunderstood aspect of Python, I will answer without a second thought: the Python import system. Just remember how many times you used relative imports and got something like ImportError: attempted relative import with no known parent package; or tried to figure out how to structure a project so that all the imports work correctly; or hacked sys.path when you couldn

(This is part of a series on the design of zest. See the list of posts here.) Many 'scripting' languages use a hashmap for their default associative data-structure (javascript objects, python dicts, etc). Hashtables have a lot of annoying properties: Vulnerable to hash flooding. If protected against hash flooding by random seeds, the iteration order becomes non-deterministic which is annoying for
Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
Example Hay could be used to configure a hypothetical Linux package manager: # cpython.hay -- A package definition hay define Package/TASK # define a tree of Hay node types Package cpython { # a node with attributes, and children version = '3.9' url = 'https://python.org' TASK build { # a child node, with Oil code ./configure make } } This program evaluates to a JSON tree, which you can consume fr
