You can solve the CodeCrafters challenges in many languages, and Go is one of them, yes. Not sure if there are books or blog posts about it though. Through the CodeCrafters portal you can access the code of other people and the related repositories, however, so that can help.

Thanks! So, I didn't consider performances at all, as it's not the goal of the project, but it would be interesting to have a look. Good idea!

Hi! The book is actually free, you can set the price to zero. Anyway, whatever way you choose, you get access to all future versions. Thanks!

Show HN: Mau v2 – A template-based markup language written in Python

Posted by thedigicat on Wednesday October 20, 2021 @06:41AM
from the show-hn dept.

Mau is a lightweight markup language heavily inspired by AsciiDoc that makes it a breeze to write blog posts or books. If you already know Markdown or AsciiDoc you already know which type of software Mau is, and you will quickly learn its syntax.The main goal of Mau, however, is to provide a customisable markup language. While Mau's syntax is fixed by its implementation, its output is created...

I just fixed it. That was caused by ANSI escape codes in Celery's output that I copied in one of my posts :shrug: Thanks again!
Re:Exploring the Amiga – Part 1 (2018) on Friday September 10, 2021 @03:25AM (#28478685)
Ouch! Thanks for the heads up, I'll fix it asap!

Thank you for sharing, guys. The next posts in the series have been in the works for a bit too long, this reminded me that I should keep writing =) Thanks!
Re:Delegation: Composition and inheritance in object-oriented programming on Friday August 28, 2020 @04:35AM (#24302636)
Thanks! Sorry for the late reply but I am not the OP, I just found your comment. This is interesting, I will look into it a bit more, as I'm not that familiar with Obj-C any more (I last used it on a NeXT 20 years ago). I think I put into the broad category of composition everything that works through interfaces, but it might be useful to discuss this particular implementation. Thanks again!

Thanks for the suggestion. Actually the rules say "Show HN is for something you've made that other people can play with." so I didn't feel very sure about it.

Yes you are right. I planned to add that part in a future release. Thanks a lot for the suggestion!
Re:I wrote a free book about TDD and clean architecture in Python on Wednesday January 09, 2019 @04:47AM (#18863570)
I just published version 1.0.2 of the book. Some readers spotted typos and bad grammar and submitted pull requests (kudos are in the changelog). You can download it from Leanpub. Happy reading!

Thank you for your comment. I considered using LaTeX or other tools, but in the end Leanpub is very easy and straightforward and, at least for the time being, I'm OK with it. Thanks for sharing your experience with Amazon and Apple
Re:I wrote a free book about TDD and clean architecture in Python on Monday December 31, 2018 @03:54AM (#18793718)
Thank you both for your suggestions, I will consider using one of these in the next versions of the book. Python is a moving target, so I will have to update the examples.
