What Hacker News says?
Django has good tutorials, I don't know about building "one app" though. I'm sure you can find some of lesser quality; Hartl's tutorial is one of the very best. If you don't mind drawing out your learning process, you could walk through Hartl's tutorial and do the equivalent in Python (probably with much help from google). So you couldn't use his code examples, but you could set up the same DB structure, the same ty…

HN discussionMiguel Grinberg's "Flask Web Development" [1] is an excellent introduction Python-based web development. You build a Twitter-clone. The book is an adaptation of the authors 18-part tutorial on the same topic [2].

HN discussionGreat topic. We sound a lot alike. I work in a different sector, but I'm also now squarely in management and have been for a while, and my previous expertise was data engineering and infrastructure. Started with zero front end ability, and also not much Python either since I'm in the size of company and industry that still accomplishes most data work in SAS, and what it can't, Informatica and DataStage. Here's where…

HN discussionI'm a huge fan of Miguel Grinberg's Flask Mega-Tutorial. It's been around for a while, but he did a major update in 2017 to bring it more up to date. https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial...

HN discussionFor my headless Pis, I attach a BT TTL serial port to the rx/tx pins. They run about $15 or less. This lets me pair to the serial port from my laptop, watch it boot the kernel, login and do whatever cli commands I need. I can also use BlueTerm on my android phone to do the same thing (though make sure you get the hacker keyboard if you go this route). Here's pretty much the article I followed, though I bumped my con…

HN discussionMaybe reverse-SEO would be good: list higher those sites with less SEO-complicance lol I have an analogy: I'm new to programming and have been trying to build a web app using python. I went through a lot of websites and youtube videos, and the most fancy-looking ones where more often than not incomplete or bad. When there was a video and the "youtuber" would hit me asking for subscription or like all the time, or fa…

HN discussion> Seniors' attitudes on HN are often quick to dismiss AI assisted coding as something that can't replace the hard-earned experience and skill they've built up during their careers. One definition of experience[0] is: direct observation of or participation in events as a basis of knowledge Since I assume by "AI assisted coding" you are referring to LLM-based offerings, then yes, "hard-earned experience and skill" can…

HN discussionTo me, every framework or web oriented language out there should have a big tutorial similar to https://railstutorial.org/book because it covers a lot of things regarding classic everyday web development which is extremely useful to beginners. So just for the existence of that book I'd say yeah, Rails is still relevant. There is also this one for flask which builds an web app from start to finish for people who like…

HN discussionFlask will take you pretty far. I'm not sure I would build a build a business around it, but it's the easiest thing I've found for just getting some code up on the web.
