  - by T. Gruhn

  In ksh, I'd use cd /usr/src/sys How should I write it in Perl? A conversion such as cd /usr/src/sys ---> chdir '/usr/src/sys' Maybe the following would be better: execute "chdir '/usr/src/sys' "

• Random number from a range in a Bash Script

  - by Jack

  Hi, I need to generate a random port number between 2000-65000 from a shell script. The problem is $RANDOM is only a 16bit number, so im stuck! PORT=$(($RANDOM%63000+2001)) would work nicely if it wasn't for the size limitation. Does anyone have an example of how I can do this, maybe by extracting something from /dev/urandom and getting it within a range? Thanks.

• Should you always write code for else cases that "can never happen"?

  - by johnswamps

  Take some code like if (person.IsMale()) { doGuyStuff(); } else { doGirlOtherStuff(); } (Yes, I realize this is bad OO code, it's an example) Should this be written so that to explicitly check if person.isFemale(), and then add a new else that throws an exception? Or maybe you're checking values in an enum, or something like that. You think that no one will add new elements to the enum, but who knows? "Can never happen" sounds like famous last words.

• #Define Compiler Directive in C#

  - by pm_2

  In C, I could declare a compiler directive as follows: #define MY_NUMBER 10 However, in C#, I only appear to be able to do this: #define MY_NUMBER Which is obviously useless in this case. Is this correct, or am I doing something wrong? If not, can anyone suggest a way of doing this, either at namespace or solution level? I thought of maybe creating a static class, but that seems to be overkill for one value.

• Build a custom drawn control for .net compact framework

  - by Hinek

  I just started on the .net compact framework. I want to draw a Sudoku field on the screen. So I put down a PictureBox and defined a method for the Paint event: private void pictureBoxPlayfield_Paint(object sender, PaintEventArgs e) { // use e.Graphics to draw the grid, numbers and cursor } This works, but you can see as the grid is drawn. So my question is, what is the right/better way to create such a custom control? Is there maybe a way to enable double buffering?

  I'd like to take a snapshot of my database, make some changes and then use the db compare functionality to identify the changes, and who knows, maybe even generate scripts to make the change. I'd like to avoid having to backup the current db and restore it as a separate db just to have a "before" snapshot. I'm guessing I shouldn't have to. Obsviously, I'm clueless about db projects and am looking to be pointed in the right direction. ty!
