How do I find out how many people use a particular PPA.  I see on a particular PPA ;  Package build summary A total of 108 builds have been dispatched for this PPA. Completed builds 108 successful 0 failed  Does that mean only 108 people have added this PPA to their sources list and installed the package?
I'd like to know how many downloads of a given package in a PPA there have been since it was first published.  I remember there was  about it about getting these metrics on the web UI, but as far as I know, it never got implemented.  But I think the number of downloads can nevertheless be obtained via the  if I'm the owner of that PPA. Any pointers?

Find all solutions to $x^2\equiv 1\pmod {91},\ 91 = 7\cdot 13$ My family PC has Windows Vista and lately it has became unusable, having strange errors and taking hours to do anything at all, so I'm installing Ubuntu 11.10 alongside it.  I went into GParted to resize the Vista partition but found that it had an exclamation point in a red circle next to it:   I tried to resize it but the Resize/Move button was grayed out.  I thought that this might have to do with the exclamation point so I looked at the information and found a load of errors:   What does the exclamation point mean?  How can I resize my partition?  UPDATE 1  I booted into Safe Mode with Command Prompt in Vista as suggested by eug and ranchkdsk c: /F /R (/F Fixed errors on the disk, /R Locates bad sectors and recovers readable information) and got:  Chkdsk cannot run because the volume is in use by another process.  Would you like to schedule this volume to be checked the next time the system restarts? (Y/)   When I reboot it doesn't run chkdsk, I'm selecting Safe Mode with Command Prompt again because I can't boot normally.  How can I stop it being used?  UPDATE 2  I tried doing what Luis suggested.  Here is the terminal output:  ubuntu@ubuntu:~$ sudo ntfsfix /dev/sda3 Mounting volume... OK Processing of $MFT and $MFTMirr completed successfully. NTFS volume version is 3.1. NTFS partition /dev/sda3 was processed successfully. ubuntu@ubuntu:~$ sudo apt-get install ntfsprogs Reading package lists... Done Building dependency tree        Reading state information... Done Note, selecting 'ntfs-3g' instead of 'ntfsprogs' ntfs-3g is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.   I still cannot resize the partition.  Ntfsfix doesn't look like it did anything and ntfsprogs is already installed.  I can access the hard drive and do backups with the Ubuntu Live CD which I'm using now.  Any other suggestions?  UPDATE 3  I attempted to use the ntfsresize command but I got an error:  ERROR: Volume is scheduled for check. Run chkdsk /f and please try again, or see option -f.   This is because I ran chkdsk in Vista Safe Mode with Command Prompt and it couldn't do it because it was in use but offered to do it at the next reboot.  I reboot and I get to the menu to the menu to choose whether to Start Windows Normally, Safe Mode, etc instead of checking the disk.  Is there any way I can unschedule?  EDIT  I just found out that I could use the -f option to force it.  It failed and told me to run chkdsk /f in Windows and then reboot twice.  But the chkdsk program is in the partition I am trying to check so it says it is in use. Can someone explain me this  please I am a bit confused?  It's from a texbook I am reading (block cipher companion)  it says that:      each weak key has  $2^{32}$ fixed points $m$ where $\operatorname{DES}_w(m) = m$ ( $w$ is a DES weak key). In other words encrypting a fixed point gives exactly the same point. To see this consider the $2^{32}$ ciphertexts after 8 rounds of encryption for which the two 32 bit halves are equal. For a weak  DES key, the round keys of the eighth and ninth rounds are equal. Thus the intermediate texts after seven rounds and after nine rounds of encryption will be equal. Since the round keys of the 7th and the 10th rounds are equal, the intermediate texts after 6 rounds and after 10 rounds of encryption will be equal. Continuing like this it follows that the plaintext will be equal to the ciphertext.    Now did not quite get :   Why are there $2^{32}$ fixed points?  And why after the eighth round of encryption the two halves must be equal? What does the author mean by the intermediate texts exactly? And how are they being equal?   P.S.: This question is not asking for what the weak keys are. I am asking for "fixed points" not exactly weak keys. For this reason I think it is not a duplicate of any other question. There is one similar question to what I've asked for which I have checked and saw that no satisfactory answer has been given there either.  Here is the similar question with no proper answers: Why can we use sample variance of the treatment group to estimate population variance of the controls? I'm taking a course on waves and oscillations using Crawford from the Berkeley series (out of print excluding international copies), and would like to know if anyone has any suggestions for a better book. We cover:    coupled oscillators, forced oscillators,  Fourier analysis,  traveling waves,    and some other topics. Any help with the topic would be appreciated. What exactly happens to the signals hitting a common mode choke? I'm trying to better understand the principles behind the common mode choke. I made a few drawings to clarify.  &nbsp; Differential Mode Signals  Differential currents (driven by differential voltages) create equal but opposite magnetic fields B in the inductor core:    These magnetic fields cancel each other out, so the net flux in the core is zero. As such, these differential currents don't "feel" any impedance.  &nbsp; Common Mode Signals  In contrast, common mode currents generate equal and additive magnetic fields in the core. That's why they "feel" a high impedance, and cannot get through (or getting through means they are highly attenuated).    But what exactly happens? I have several theories, which I will describe below.  &nbsp; Common Mode Signals - Theory 1  My first thought would be that the common mode signal hits the choke and creates a magnetic flux inside. By doing this, lots of energy is lost (hysteresis and perhaps other effects) as heat. Only a small part gets through:      What kind of common mode choke would behave in this particular way? "Burning up" the voltage spike seems a very desirable effect to me.  &nbsp; Common Mode Signals - Theory 2  Perhaps the voltage spike doesn't really get the chance to build up much magnetic flux in the core, or maybe the core is simply not "lossy" enough. The voltage spike bounces off the core and turns back. Only small part gets through:    Although the system on the right side of the choke is protected, the system on the left has to deal with reflected signals. Nasty things like standing waves might appear.  &nbsp; My questions  I've got a few questions for you:   Do you think theory 1 or theory 2 is most plausible? Do you think certain types of common mode chokes tend to behave as described in theory 1, others like in theory 2? Perhaps both of my theories are just plain wrong. If so, what actually does happen?   Please enlighten me. No Time in Top Panel (Gnome Classic) I've been using Ubuntu with Gnome Classic for a while and I've noticed recently that in the "Indicator Applet Complete" in the Top Panel, my name and the clock have disappeared.    I think it happened a while ago when I was messing around with packages. Every time I did apt-get... it would say "the following packages can be removed by apt-get autoremove", so I did it and then the clock and my name stopped appearing.   Can anyone help me? Thanks. It would be greatly appreciated. I'm stuck underground.   I can't mine any further to reach lava. There is no water nearby, and zombies can't reach me.  I can't see to find any blocks to suffocate my character.  NBTEdit and similar programs don't work on Mac, so I can't edit my save file to escape. I have hardly any blocks so cannot jump and lay my way up. I can't see, and do not have any torches, so can't make a staircase back up. I don't want to make new save as I have an awesome house filled with stuff that took me ages to find.    How can I get back to the surface?

Story about workers repeatedly doing trivial work I'm trying to remember a (short) story I read in school some time ago. I don't have much, but here it is:   Numbers of workers are assigned to trivial task, like changing broken lightbulbs (or something similar). Once they finished their daily work, another group of workers are putting the broken lightbulbs in again, allowing for an endless, trivlal working circle.   I know that isn't much, but maybe someone has an idea, thanks. Javascript get date in format iOS: How to change app language programmatically WITHOUT restarting the app? I recently ran the iTunes 10 installer in Wine and everything seemed to go well. Then, when I tried to run it, it would constantly crash/and the appearance would be glitchy. After looking at the Wine website, it turns out that iTunes 10 has a 'garbage' rating of Wine compatability.  Now I'm trying to remove/uninstall iTunes, QuickTime, and the other applications that come default with installing iTunes (such as Bonjour, etc.). However, when I run the 'uninstaller' that wine provides for the programs, it instead executes what appears to actually be the original installer! I've tried deleting all the configuration/data files in my Wine's file-system, but to no avail.  Any help is greatly appreciated!  Edit1: After re-running the uninstall process and then rebooting, the program (iTunes 10) still remained installed. Calendar date to yyyy-MM-dd format in java $\sum_{n=1}^\infty \log \frac{n+1}{n}$  $\sum_{n=1}^\infty \log \frac{n+1}{n}$ =  $\displaystyle\lim_{n \to{+}\infty}(\log2 - \log1)+(\log3-\log2)+...+(\log(n+1)-\log n)$=$\displaystyle\lim_{n \to{+}\infty}\log(n+1)\to \infty$.
