10.3.2019
Manuel Matuzovic makes the point that in order to use CSS grid in some fairly simple markup scenarios, we might be tempted to flatten our HTML to make sure all the elements we need to can participate on the grid. What we need is subgrid and non-buggy display: contents;, so I'd like to think in...

The Bottleneck of the Web
5.3.2019
Steve Souders, "JavaScript Dominates Browser CPU":
Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus...
Minimum znalostí pro práci s SQL databázemi
2.3.2019
Roky píši o Postgresu, a o tom jak správně používat relační databáze. Relační databáze byly navržené tak aby se používaly jednoduše a efektivně, a aby je mohli použít jak programátoři, tak běžní uživatelé. To, že s relační databází může pracovat neprogramátor (koncový uživatel) je v podstatě ...
Get File MIME Type from Command Line
28.2.2019
I’ve gotten skilled at shell scripting over the years. I love a good GUI but knowing how to automate makes you a much more powerful engineer. Much of my scripting requires recursing over directories and processing a file if it meets a given criteria, which is often file extension or MIME...
List USB Devices from Command Line
27.2.2019

Moving a Self-Hosted WordPress Site to WordPress.com
26.2.2019
I have a habit of getting some hosting when I need a new WordPress site. That is, a self-installed, self-hosted WordPress.org site. That's served me well over the years. I like my control. But along with that control comes a certain level of extra responsibility that sometimes just isn't worth...
JavaScript Proxy
26.2.2019
I’ve always loved the flexibility of Objects and prototypes in JavaScript, but for a long time, I felt that a level of dynamism was lacking. JavaScript eventually added get and set methods for object properties, which was an awesome step, but there was still room for improvement....

Did you know you can triple-heart things on CodePen? We’ve had that little not-so-hidden feature forever. You can click that little heart button on any Pen (or Project, Collection, or Post) on CodePen to show the creator a little love, but you can click it again and again to heart it just that...
Awesome Analytics with Keen.io (Sponsored)
21.2.2019
As a young developer, I would often make decisions based on what I considered to be common sense or what I would envision appealed to users. What a mistake. As I’ve become more experienced as a developer and a businessman, I’ve realized that analytics are the best way to make...

Welcome to My New Office
19.2.2019
My first professional web development was at a small print shop where I sat in a windowless cubical all day. I suffered that boxed in environment for almost five years before I was able to find a remote job where I worked from home. The first thing I told myself when leaving that first...
Using Slack Slash Commands to Send Data from Slack into Google Sheets
18.2.2019
Since I work from home, most of my daily work interactions happen through Slack. It’s my equivalent to the water cooler. A place to hang out and discuss ideas with friends. I’m part of a book recommendations channel. People share books all the time, but they disappear quickly, lost in a sea...

17.2.2019
When we started Discourse in 2013, our server requirements were high:
1GB RAM
modern, fast dual core CPU
speedy solid state drive
I'm not talking about a cheapo shared cpanel server, either, I mean a dedicated virtual private server with those specifications.
