Now will they? I have my doubts. Here in Belgium, we have one of the most dense road maps of the world. Traffics jams, road constructions, pits in the road etc. It's even hard for a human being like me to go from A to B. So how would a piece of machinery do better?

Hello All. I have a program that automatically restarts itself atfer a certain amount of time. I am doing this to test some things out. The program is wrapped in a jar.

It runs fine and everything, I just want to see the output. How would I accomplish this. this is my restarting code. public void Restart() throws IOException { try { final String javaBin = System.getProperty("java.home") + …

I came across a program [SelfNote](http://selfnote.pen.io/) which stores all the text we write and the password in itself.No other file is created (the EXE changes its size as we change it's contents) . It is a standalone exe with all the content within it. How can an exe modify itself ? Is this possible in VB.net ??

I have been programming for quite a while in Python but have just started to learn OOP properly. I find it really confusing and I don't really understand it. Especially the implicit self that python automatically passes. It just isn't clicking, really. May someone provide an easy explanation of what classes and objects are in general and how they are used in Python?

I have a problem that I've racked my brain with for two weeks without success. I have a table named 'user_answers' containing columns 'user_answer_id' and 'user_name'. Each 'user_name' has 25 rows. I'm trying to compare/count the number of rows where user A and user B match answer_id. SELECT COUNT (*) user_answer_id FROM user_answers WHERE user_name = Jake LIKE (SELECT user_answer_id FROM user_answers WHERE user_name = Betty) The above returns 25 rows from Jake. There should only be 6. I've tried substituting LIKE with IN but get every row in the table. Any help with this would surely be appreciated.

TABLE1 ~~~~~~ COL1 | COL2 1 | 11 1 | 12 2 | 12 2 | 13 111 | 21 111 | 22 112 | 22 112 | 23 TABLE2 ~~~~~~ COL1 | COL2 | COL3 1 | 11 | 201 1 | 12 | 201 2 | 12 | 201 2 | 13 | 201 111 …
