Never ever touch a programmer
This is a technical license plate block example. We don't know whether it is working or not, however, the idea is very good. When you drive through some of the junctions, the camera captures the license number and convert it into text with OCR, and then insert them into the database.

“Native vs Web†Is Total Bullshit
The web is dead. HTML5 is the be-all end-all of the future. Users are spending more time on apps and less time on the web. You can do anything on the web that you can in a native app. Yawn. Here’s how I feel whenever I hear/read anything about the overplayed “Native Versus Web†argument: It’s not an either-or decision Why aren’t we still arguing over “Print vs Digital� Well, because (most) people understand that each medium has its place in thi...
