• Perl: How do I remove the first line of a file without reading and copying whole file.

  - by dr jerry

  I do have a whole bunch of files in a directory and from every file I want to remove the first line (including carriage return). I can read the whole file into an array of strings and write all but the first element to a new file, but that looks a bit cumbersome to me are there better ways? Oh the prefered language is Perl.

• automate operations within a Virtualbox machine

  - by samb

  Hi, I'm Having some trouble in a vm that seems to occur only once in a hundred during shutdown/reboot. To help the debug, I'm thinking to write a script that runs on my desktop, which starts the vm and automate operations for a huge number of times (keyboard key pressed) whithin it. (VirtualBox preferred). It's just exactly how a script using the expect lib would do with a program in command line. I'm not sure it's possible, but anyway, if anyone has an idea... Cheers

• Writing direct to disk with php

  - by Jurander

  I would like to create an upload script that doesn't fall under the php upload limit. There might be an occasion where I need to upload a 2GB, or larger file and I don't want to have to change the whole server execution to above 32MB. Is there a way to write direct to disk from php? What method might you propose someone would use to accomplish this? I have read around stack overflow but haven't quite found what I am looking to do.

• Why is Perl commonly used as CGI scripts?

  - by Michael Vasquez

  I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

• Emacs align-regexp on = but not ==

  - by Karl

  I am working in Haskell and frequently come across code similar to the following: func i j | i == j = i | otherwise = j I want to align on the '=' character using align-regexp but don't have the elisp knowhow. I have tried just doing " = " without the quotes, but this inserts an unwanted space character before each '='. I have found a proposed solution here but I can't seem to get that to do anything at all. Please help me write a function or hard-coded macro that will allow me to set a keybinding for this.

• avoiding the tedium of optional parameters

  - by Kyle

  If I have a constructor with say 2 required parameters and 4 optional parameters, how can I avoid writing 16 constructors or even the 10 or so constructors I'd have to write if I used default parameters (which I don't like because it's poor self-documentation)? Are there any idioms or methods using templates I can use to make it less tedious? (And easier to maintain?)

  Hi, I am trying to make an arcade machine. The user will purchase credits, which will allow him to play for X minutes. I want to write "9:42 minutes left" at the left corner of the screen, even if he's playing a full screen game (UrbanTerror, for example).

• rails, activerecord callbacks not saving

  - by Joseph Silvashy

  I have a model with a callback that runs after_update: after_update :set_state protected def set_state if self.valid? self.state = 'complete' else self.state = 'in_progress' end end But it doesn't actually save those values, why not? Regardless of if the model is valid or not it won't even write anything, even if i remove the if self.valid? condition, I can't seem to save the state. Um, this might sound dumb, do I need to run save on it?

• How do I protect my website from javascript injection attacks when using rich text editors?

  - by VJ

  Hi all I am using the markitup editor to get the value for one of my fields and storing it a sql server 2008 db. Now I guess the problem is people having script tags and javascript in the editor and injecting malicious scripts and I have my validate input turned false. So can anyone suggest me a way to write a custom validation method that maybe checks for script tags and removes them...or just guide me through the steps i need to do ?...also are there other things also that I should be worried about..?
