You should hire an old programmer. It’s true! Sure.. older programmers are not going to work as many hours as someone fresh out of college.

In the last couple of weeks I have started to see CSS Grid layout based frameworks and grid systems appearing. I’m actually surprised as to how long it has taken, but I am yet to see one that adds any value at all over just using CSS Grid Layout. Worse, the ones I have seen ... You do not need a CSS Grid based Grid…
Tomorrow, two high-speed rail lines open in France, providing new corridors for trains to slice through the countryside at 200 mph (320 km/h). One is a 302-kilometer link that will connect Paris to…
Heap's algorithm for constructing all permutations is efficient and simple but not easy to understand. This article explains Heap's algorithm by example.
Apple is apparently not eating its own dogfood when it comes to equations.
I typed up some quotes from Chris Lattner on a recent panel discussion about Swift.
After seeing the poor feedback of Watson in Bridge Crew, I decided to take my four digital assistants for a spin. After 21 questions across four assistants, I learned that Alexa cannot give basic information about Amazon Prime videos, none of them can properly understand which movie you're looking f
