But beyond coding, programmers need to do other work as well, they need to fix bugs reported by users, they need to write documents for their codes. Also, they often need to answer questions from customers, bosses and colleagues. What do they often say when they are facing different sort of questions? Today we share some.It's done.

This task will be easy.Yeah, I tested it. I'...

Not every one who writes code is a programmer. Programmers are people who live with programming. There are 4 types of programmers: scientist, coder, expert and artisan.Scientist, they are more like mathematicians rather than programmers. They invented various theories, algorithms and terminologies. Proofs and calculations in textbooks are all from these people. Moreover other programmers more or less benefit from their work. Sometimes one paper published by them can change the way of thinking of the whole industry. But they usually do not like to commercialize their theory. In contrast, they p...

Programmer is a lifetime occupation. But first, as a programmer you need to love programming, rather than just an occupation to achieve other goals in life.Now if you plan to spend decades of life on programming, then you should continue to think about what is more efficient. In other words, how are you different from who you were a decade ago and how will you be better than who you are now a decade later?In my opinion, a programmer, regardless of his work, should improve himself in three aspects.First of all, keep the curiosity of the unknown, try to broaden your views.If you are proficient i...

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. Therefore, this license plate on the car becomes a SQL injection. This picture tells us -- never trust user input.Author : 陈皓 Source : http://coolshell.cn/articles/6639.html#more-6639...

Once or twice a month I get the question from an aspiring entrepreneur that’s been pushing their idea forward in hopes to (very soon) create a company out of what they’ve been working so hard on. They’ve spent countless hours working through all the details of what this new product will do, who they’re going to partner with and what they’re going to charge for it.
