I have recently published a web service to my site through Visual Studio. I accidentally selected "Delete Existing Files" option!
How do I get back my deleted files from the server?
Why, you would go to your nightly back-ups and restore the files. You do have a backup solution in place don't you? Because if you don't, then you're out of luck.
In theory, if you stopped the server and yanked those hard drives right now, then forensic data recovery could POSSIBLY get some of the files back.
This might not be relevant, but: the one time this happened to me I was able to decompile the executable. The result wasn't perfect, but it got all the really tricky bits back.
IF. You don't have backups.
IF you're hosting is in a remote hosting facility call them ASAP.
and ASK if they have an automated BACKUP. You may just be lucky.

I need to take a provided .bin file as input, convert it to string representations, and do a bunch of other fun stuff. The issue is that we are being graded on the school's linux server which I have almost no idea how to use.
On the Linux machine I have created a directory for my program called "read". Inside is my "read.cpp" file. I'm guessing the .bin need to go in this directory, since "read.cpp" utilizes it as input, but I have no clue how I can get it there.
Any help would be greatly appreciated.
I wound up using WinSCP to transfer the file. Makes it super easy. I've used it before and completely forgot it was a thing. Cheers!

I have installed VirtualBox and an Ubuntu on my Windows machine. But after a while I needed more disk space, the problem is that my dev/sda1 partition (where I need more space) should be resized. Resizing it with the Ubuntu installation wizard will erase all the data (I have an Apache server, MySQL, etc... on it !).
My question: is it possible to resize the partition without losing the data ?
Or at least is it possible to restore it after the resizing ?

Everytime i run my software i can access from winhex the memory and read the information my software pass through memory like emails, phones, etc. Is there any way to secure that or at least to remove this information from memory ?
A program written to use the debug API, run under the authority of someone who can run a debug API capable app, cannot be protected against. If it could, you couldn't debug your software.
There is a privilege model:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa379306(v=vs.85).aspx
But if someone is running with sufficient privileges to run WinHex and look at that information, then no. There's no way to exempt your program from inspection from those who have the privileges.

We currently have a CF 10 Instance which we are monitoring via seeFusion.
We currently have 12GB of memory on this particular machine and whilst monitoring it within the server monitor it never skips a beat and appears to be quite reliable.
However whilst in seeFusion, the CF Instance appears to only have 486MB of memory...
I would like to bump this up as since it only has 486MB of memory, simple things like running a cfindex on a dataset of 40,000 records makes the entire server crash.
Any ideas on how to go about adding more memory to the CF Instance? Either by the Admin or programatically if this is possible ?
You can adjust the size of the JVM Heap in the Coldfusion Administrator in the Java and JVM section. This thread has some useful information and links: http://forums.adobe.com/thread/1027056

A few of my sites got a code injection and it is the first time I am dealing with something like this. Is there any specific procedure that I can follow to debug the code and find where the source of the injection? Also, is there anything that is ColdFusion specific regarding this matter?
This question is perhaps better asked on Server Fault, not Stack Overflow. That's why you've got the close vote (it was not from me).
Update your question's tagging to include the correct ColdFusion version.
The ColdFusion 9 lockdown guide (which I found by googling "coldfusion lockdown guide", btw) is here.
Make sure you are fully patched. Fortunately Adobe are still releasing security patches for 9.0.1. Advise us here whether you are already up-to-date, or whether you are short any patch(es).
Look for files called h.cfm (in your web root directory, as well as the /CFIDE directory structure). This file is a known vector for a security hack which did the rounds at the beginning of the year.
