10 years ago, systemd was announced and swiftly rose to become one of the most persistently controversial and polarizing pieces of software in recent history, and especially in the GNU/Linux world.

Most CPU architectures in use today have an instruction called popcount , short for “population count”. Here’s what it does: it counts the number of set bits in a machine word. For example (assuming 8-bit words for simplicity), popcount(00100110) is 3 and popcount(01100000) is 2 .

* { box-sizing: border-box } FTW

Apple can comply with the FBI court order
Earlier today, a federal judge ordered Apple to comply with the FBI’s request for technical assistance in the recovery of the San Bernadino gunmen’s iPhone 5C.

Making Facebook's native mobile app faster using HTML5
When we started what became Sencha, we made a bet on the web: a bet that modern application development didn’t need anything except the browser, a great set of frameworks and a great set of tools.
