Suppose you have a HTTP request to be sent but don’t care about the result or errors. This request is sent through a function which is usually called inside a goroutine and is not in any way a core aspect of your main logic. The only important part is forming the actual request and the payload. When you wrote this function, you did not write tests as it would be a pain to make the function return something and check it.

Working with J2ME on Linux in 2017

I recently had to work on the J2ME platform for a course at my university. It is an old technology and does not have many recent articles about using or installing J2ME on Linux. J2ME SDK has had no support for Linux for a long time. The SDK 3.x only has support for Mac and Windows. The last version available was by Sun which is called the Sun Java Wireless Toolkit 2.

Similarly, \w matches word chars.
