I'm a Computer Science student at the Scuola Superiore of the University of Udine. I've been interested in Computer Science since my third high-school year, and thus I've decided to apply to join one of the Schools of Excellence, and succeeded in this task.

comment Why are Ethernet/MAC addresses needed?
erm... computer <-> IP address is not an injective mapping. I'll reword my question: How do computers know that they should ignore the data? Without MAC address they cannot tell which one on the network should process it... since more than one of them could have the same IP?

comment Opened a JPG picture with notepad, pasted all the “text” to a new notepad file, changed to .JPG and it no longer opens. Why?
@Zonder And what do C strings have to do with that? C strings exist only in RAM. A file cannot contain C strings. Also Windows programs are usually written in .NET languages, so C doesn't have anything to do with all that in the first place.

comment How can I pipe console output directly to Notepad?
- is often used to mean "read from stdin", so this isn't strictly limited to vim. Other editors use -i (e.g. kate).

comment How to force a process transmit over UDP instead of TCP?
@JordanDoyle As I said, nothing special will happen except that more packets will be dropped and the connection will get slower and slower, because the sender will be filling all the link capacity. You are just increasing the traffic in the network uselessly and you might cause a congestion of the network.

@JordanDoyle No. That will just make the connection slower because the receiver will have to drop the extra packets, which will then require retransmission.

comment Can't copy text from a pdf file
Note that Okular can run on Windows. In fact a lot of KDE software can run on windows.

comment Windows 7 says a 8.6 GB file won't fit in 14.7 GB space?
Note that the error message explicitly mentions the file system and not the drive!

comment Can I make a video not downloadable?
@AK4749 That's security through obscurity and it doesn't work. Everything can be reverse engineered(an example is the CCS system).

comment Hyper Threading vs Overclocking
@BlueRaja I believe any multiplayer game will have at least a thread listening & communicating with the server/other players and a thread for user's interaction(+ eventually rendering tasks or running AI of opponents). Also the server for such games probably use one thread per client.

comment Hyper Threading vs Overclocking
The "is one application running" is completely wrong. Games are (generally) highly multithreaded, and keep in mind that thread != process.

comment How to test for harddisk damage preventing it from booting?
The first command shows a table where I can see that attribute Reallocated_Sector_Ct is FAILING_NOW. Also the short test reports a status of Completed: unknown failure. I've just launched the long test to see a more verbose explanation, even though I guess the only option is to replace the HD...

comment How to test for harddisk damage preventing it from booting?
@AlvinWong It uses BIOS/MBR. The recovery disks where the ones I created right after installation(I don't rememeber if it was through an Acer program or if from Windows 7 utilities...). I was able to save all important information of the hard disk and I already removed/recreated/formatted the partitions multiple times.
