First of all, I don't know where to put this. I had a thread in the advanced physics homework help (https://www.physicsforums.com/threads/calculating-the-transfer-function-for-dark-matter-numerically.1052335/#post-6883072) but it just vanished overnight. I never got a notification or something...

Say you have a large text file on your hard drive that you edit such that its content is fully erased and you save it that way. Then you delete the file. Is the content still on the hard drive? Usually, deleting a file only deletes the address where the file is on the hard drive and the content...

Anyone has the suggestion on this? I deleted a couple of photos stored on SD card and i heard it's highly possible get back them. Actually, I tried a few 'so-called' data recovery apps, none of them work. Do you guys have any recommendation on this? thanks in advance

Hi guys, I've accidently formatted my PC with lots of PST files which were on drive c:. I REALLY need to recover them ASAP. Which tools can I run in order to recover those files? I've already tried the following: 1) Recover my files 5.x - both full partition recovery and PST file 2) Hetman...

Homework Statement Given: z = f(x,y) = x^2-y^2 To take the partial derivative of f with respect to x hold y constant then take the derivative of x. ∂f/∂x = 2x What I don't understand is why such would equal 2x, when the y is still there it just isn't variable and is ignored. Wouldn't it be...

I am returning a defective computer, I uninstalled all my installed programs and deleted all the files I put into the computer. I empty the recycle bin. I went into the program files folder and deleted my installed files. Is everything completely deleted?( I don't think so.). What else can I do...

using namespace std; class A { int i; public: A(); void Set(int& i){this->i=i;} void Print(){count<<i<<endl;} }; int main() { int *i=new int; A ra; i=10; ra.Set(*i); delete i; ra.Print(); } I think after delete i, the value in Set will also be deleted. Isn't...

I finally got an answer to my question by a poster on this site, and my thread gets removed. I broke no rules, so it seems some mod out there drunk with power. It is utterly pitiful, as I thought this was supposed to be a legitimate physics website, not one with corrupt mods.

Recently I discovered a file (dated Feb. 13, 2011, time 8:07 P.M. (EST)) that cannot be deleted and does not respond to any commands, such as move, rename, open, etc. I have "unlocker assistant", but it doesn't work here. The date stamp corresponds to a time when I was surfing Physics...

This is from a calculus textbook (self-study), but my problem is not with the calculus material itself. I feel I'm missing something (obvious!) from algebra. In any case: The problem statement Find an appropriate number L (a limit), and a deleted neighborhood N of a, such that a given e...

My comp recently just caught an virus and I have tired many anti-virus programs to remove it and so far, no luck. Avast reported the file that is infected, but is unable to delete it. So I decided to check it myself, it's a file in my systems/drivers and when I tired to delete it. It saids the...

I lost some photos on my HP camera using a SAN disk memory card. I think I reformatted the card accidentally, but the result, anyway is some of my photos are gone. Is it possible to get them back?

OK, there is this problem which I need urgent help with. A separate user account was made on windows XP to do some very important work. Later on that account wasn't needed so that account was deleted. Unfortunately, the option chosen was to delete the user's files along with the account. And...

Last night someone hacked the World Artist's Network, which was MySpace very largest forum, and deleted the whole thing. For hours I couldn't log on and thought it was just a server problem or something someone could easily fix. Instead, today, word started filtering around that someone had...

Hi, I've done something really stupid. I found a Newton's Method program on the internet and copied it to my TI-83 Plus. This program let you put the function in Y1 and its derivative in Y2. Then, you ran the program, and once you input your first guess, you would hit the ENTER key as many times...

IS it possible to save songs back onto the hard drive when checking in despite the fact that the song has since been deleted from both the playlist and hard drive? It appears on checking in, that the song disappears totally in OPEN MG software. Any help much appreciated as I deleted songs...
