A long time ago, I used to know all MySQL commands by heart. Now I am re-learning them, but this time with MariaDB, and I learn best by writing things down. So here is the cheatsheet to have a way of looking up commands quickly.
Since I moved to Linux for work I started to look up and collect the git commands I need most. On Linux I do not have my beloved GitUp app which is an amazing visual and fully keyboard controllable git tool available for MacOS only. Here is my list of git commands. As usual I created this collection so I know where to copy+paste commands from ;).
I had planned building the kata for
Number.parseInt() already a while ago. Starting to work I discovered very quickly that this seemingly tiny kata is quite a rabbit hole that offers a lot of things one can learn. Especially about how things evolve in the spec and how to read the spec, fortunately this is a pretty easy to read part of the spec.
This is post #3 in the category "Browser Tools", focusing on understanding the loading times by charting them in a Waterfall chart. In part 1 and part 2 about Resource Timing I covered the attributes
initiatorType. Now I want to understand what happens after a resource starts loading and what do some attributes mean, like
responseStart, to mention the most relevant ones.
This is post #2 about Resource Timing, with a focus on understanding loading dependencies. In part 1 "Resource Timing - The API" I covered the attributes
startTime. Now I will try to show how the API can be used to see which resources block each other, which is the step to understand before optimizing site speed, a very essential step to know what is the right thing to optimize.
I want to explore the Resource Timing API, one of the Performance APIs, accessible via
in all modern browsers.
This post is the start of a series of blog posts about browser tools, in which I look into any kind of tools or APIs in and around the browser, things web developers will hopefully find useful.
It was the second time that we did Tetris as our task for the JSCodeRetreat and I have to say, that the participants' comment made me realize that we are on the right track. Though not all comments were purely in favor of Tetris, I think Tetris is the better task for a (JS) CodeRetreat.
It was Evren who triggered the idea of using Tetris as the task for the next JSCodeRetreat. And I have to say it was a good idea, it was a bit more challenging than the Game of Life and left more room for discussions and also allowed to explore more (software) design challenges.
The callback-hell times are long over. We have better tools now. But which of the new kids on the block do you want to play with? In this meetup, last night we tried out async functions, also known by the name "async/await". It was a fun learning experience. Keep reading and get inspired.
While refactoring some badly tested code, a pattern of how I extract dependencies emerged. The actual intention was to improve the testability. In this case dependency injection is the tool that helped me. Read here to find out the steps I found to separate the dependencies.
