Explore the basic language constructs of Tcl, which include user input, output, variables, conditional evaluation, looping, and simple functions.

Phoenix 1.7 is dropping path helpers in favor of a new concept called verified routes. Let's see how it handles typos, missing paths, arguments, and query params.

Previously, an article made the rounds concerning Undefined behavior that made the usual Rust crowd go nuts and the usual C and C++ people get grumpy that someone Did Not Understand the Finer Points and Nuance of Their Brilliant Language. So, as usual, it’s time for me to do what I do best

RSpec custom matchers can be written using plain old objects.

You sometimes want to add a string to an existing data structure. For example, the C++17 template ‘std::optional’ may be used to represent a possible string value. You may copy it there, as this code would often do… std::string mystring; std::optionalstd::string myoption; myoption = mystring; Or you can move it: std::string mystring; std::optionalstd::string myoption; myoption … Continue reading Move or copy your strings? Possible performance impacts

Add tagging with no extra tables using Postgres array fields and Ecto for an easy an simple solution.

In this tutorial we're going to be building video object detection in Elixir using Nx and Bumblebee.

This tutorial shows how to use embedded templates in Phoenix 1.7 when the format of the template is not HTML.

Copy to a user's clipboard with Phoenix LiveView.

Build cross-platform desktop apps with JavaScript, HTML, and CSS.

As engineers we spend a lot of our time debugging problems, yet it's rarely taught as a skill in its own right. Some bugs are difficult enough that they can seem borderline impossible to solve, especially for devs toward the junior end of the spectrum. There's no worse feeling than being stuck on a hard problem, not knowing how to proceed. Of course, the right thing to do if you're stuck like that is ask for help; from your team, from other engineers in your org or social circle, from random strangers on the internet. As a random stranger on the internet then, this post is my attempt to help get you unstuck if you find yourself in that situation.

This post describes how we used Elixir and Opus in one of our services at Tefter, which implements bookmarking collaboration in Slack. My relationship with Slack I remember, when Slack started getting viral and it was set as the main chat app at work, I was very reluctant to use it. I was quite happy with IRC and always in favour of open protocols. Since it supported an IRC / XMPP gateway, tweaking my irssi config and later finch was trivial and my overall experience was good.

I am not sure if Zorbash had the idea to create Opus while we worked on the same project at Quiqup, but if there’s one thing I can be sure…
