    • Parsing SQL - Strumenta

      The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However

      • Why I use attrs instead of pydantic

        This post is an account of why I prefer using the attrs library over Pydantic. I'm writing it since I am often asked this question and I want to have something concrete to link to. This is not meant to be an objective comparison of attrs and Pydantic; I'm not interested in comparing bullet points of features, nor can I be unbiased since I'm a major contributor to attrs (at time of writing, second

              I spend an awful lot of my day in Unix terminals running shell commands. For some reason, the variance in efficiency between different people when using the shell is huge: I know people who can run rings around me, and I’ve come across more than one paid professional who doesn’t use the “up” key to retrieve the previous command. I chose that last example very deliberately: most of the commands mos

                  A mega tutorial with dozens of examples on how to use the pathlib module in Python 3 When I started learning Python, there was one thing I always had trouble with: dealing with directories and file paths!

                  • The AI-Native Software Engineer

                    An AI-native software engineer is one who deeply integrates AI into their daily workflow, treating it as a partner to amplify their abilities. This requires a fundamental mindset shift. Instead of thinking “AI might replace me” an AI-native engineer asks for every task: “Could AI help me do this faster, better, or differently?”. The mindset is optimistic and proactive - you see AI as a multiplier

                      Concurrency is not very intuitive. You need to train your brain to consider what happens when multiple processes execute a certain code block at the same time. There are several issues I often encounter: Failing to recognize potential concurrency issues: It's not uncommon for both beginner and seasoned developers to completely miss a potential concurrency problem. When this happens, and the concur

                          • Python Dependency Injection

                            Writing clean, maintainable code is a challenging task. Fortunately, there are many patterns, techniques, and reusable solutions available to us to make achieving that task much easier. Dependency Injection is one of those techniques, which is used to write loosely-coupled yet highly-cohesive code. In this article, we'll show you how to implement Dependency Injection as you develop an app for plot

                                  I’ve been writing a lot of database access code as of late. It’s frustrating that in 2023, my choices are still to either write all of the boilerplate by hand, or hand all database access over to some inscrutable “agile” ORM that will become a crippling liability in the 2-3y timescale. This post is about how I want to use databases, from the perspective of an application server developer—not a DBA

                                      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
