The Nostr Protocol - NIP01
What is Nostr? Nostr stands for "Notes and Other Stuff Transmitted by Relays". It is a new type of social experience on the web where "dumb" relays can be used to send messages from one user to another, in a secure, censorship resistant manner. Since it is not P2P it has a chance of working. Nostr Relays Relays are lightweight, easy to set up, and can run in as little as 5MB of memory. A list of r

Tailwind CSS Resources you wish you had.
Background story This week I decided to take a look at Tailwind CSS and create a simple e-commerce website. The first thing I noticed is how well the documentation was written. Even if Tailwind is your first CSS framework, you will easily be able to navigate through different sections😉. Some areas like Navigation, they have uploaded a few video tutorials to help you create a nav with ease. All se

Actually, if you think about it, even your collection of stories c
🚀⚙️ JavaScript Visualized: the JavaScript Engine
JavaScript is cool (don't @ me), but how can a machine actually understand the code you've written? As JavaScript devs, we usually don't have to deal with compilers ourselves. However, it's definitely good to know the basics of the JavaScript engine and see how it handles our human-friendly JS code, and turns it into something machines understand! 🥳 | Note: This post is mainly based on the V8 eng
Why Codewars is the best way to learn a new programming language!
Why Codewars is the best way to learn a new programming language! As a Programmer, you'll probably find yourself having to learn a number of programming languages whether it be for work or just for fun. In this blog, I will share what I personally think is the best way to learn a new language provided you're fairly proficient in one of the same paradigm. I'll be taking a stab at learning C# with p
WSL Tips: Starting Linux Background Services on Windows Login
WSL Tips: Starting Linux Background Services on Windows Login Note: I'm cross posting this from my blog to dip my toe into dev.to More and more developers are finding out that the Windows Subsystem for Linux (WSL) is pretty great. Being able to transparently use a ton of established *nix tooling on Windows can make your machine a kind of best-of-both hybrid as both a user and a developer. Updates
Why you should deploy on Friday afternoon
Don't deploy on Friday afternoons! This expression is taken as programmer wisdom but I hate it. I'm going to try and kill it, with words and experience. The motivation behind it is sound. I don't want to spend my Friday nights debugging a production problem either. To me the expressions smacks of unprofessionalism. Software development as an industry has a poor reputation and phrases like this do

MixとOTP 06: ETS
gumi TECH for gumi TECH Blog Posted on Apr 23, 2019 • Updated on May 14, 2019 本稿はElixir公式サイトの許諾を得て「ETS」の解説にもとづき、加筆補正を加えて、ElixirにおけるETSの使い方についてご説明します。 プロセスを探すには、それらの登録先プロセスにメッセージを送らなければなりません。複数のプロセスから同時にアクセスされると、登録先プロセスがボトルネックになってしまいます。そこで、ETS(Erlang Term Storage)について学習し、これをキャッシュメカニズムとして使ってみましょう。 ETSをいきなりキャッシュに使わないようにしてください。アプリケーションのパフォーマンスを記録および分析し、どの部分がボトルネックなのかを明らかにするのが先です。そのうえで、そもそもキャッシュすべきか、何を
git bundle
I had an interesting problem at work the other day. We'd hired some external contractors to build an android app for us, and now we needed to get the code from them and into our private GitHub. The problem was, I couldn't quickly get them access to the repo since there's a fair amount of process involved in getting those approvals. They also didn't have enough seats to add me as a contributor to t
