how to reset gnome panel? I think my gnome-panel is messed up because I alt+right click it and nothing pops up.  I'm on 12.04, classic gnome desktop.  so I used locate and found gnome-panel in .gconf somewhere, how do I clear just gnome-panel's settings so that I can add things to my panel again?   edit:  matt: ~/.gconf $ find|grep -iw panel ./desktop/ibus/panel ./desktop/ibus/panel/%gconf.xml ./apps/gnome-settings/gnome-panel ./apps/gnome-settings/gnome-panel/%gconf.xml How to get sudo to prompt you for a password each time I was using this:    To try and create numbered examples in my document.

No space left on device -- but there is space I'm running an Ubuntu 12.04.1 server in a VMware virtualized environment that has a strange issue. Twice now, at seemingly random times, the machine has suddenly been unable to write to the root partition despite plenty of space seemingly available. I'm at a loss trying to figure out what's wrong.  "df -h" shows all mounted volumes with 40% or more free space. Both times this has happened, rebooting resolved it for a few minutes, and then it was back to saying "no space left on device." Restoring it from a snapshot seems to fix it for longer, but since this has now happened again, I'm not sure what to do with it.  If it helps, the machine is a network print server running CUPS 1.5.3 and Samba 3.6.3. How to count number of bases and subspaces of a given dimension in a vector space over a finite field? Let $V_{n}(F)$ be a vector space over the field $F=\mathbb Z_{p}$ with $\dim V_{n} = n$, i.e., the cardinality of $V_{n}(\mathbb Z_{p}) = p^{n}$. What is a general criterion to find the number of bases in such a vector space? For example, find the number of bases in $ V_{2}(\mathbb Z_{3})$. Further, how can we find the number of subspaces of dimension, say, $r$?   I need a justification with proof. I have a formula, but I am unable to understand the basic idea behind that formula. booting windows 10 spends too long In august 2015, I have upgrade my laptop from windows 8.1 to windows 10. But it spends always 10 minutes to boot it. It is not normal that it spends so long. What can I do for boot him faster? Below some information about my laptop.   age: +/- 2 year (on august 2015) edition: Windows 10 Home   File trace are removed.  Update:    I must also say that always there comes a windows update, I have the same problem again form slow booting. Is it good that I turn off the updates? If yes, how can I do that? Also it is in periods that my pc booting to slow. Some time it is like normal (a few seconds) and other times a few minutes. I don't know how it comes that it is fast or slow. How much does it cost to have a custom ASIC made? I have browsed several ASIC manufacturer's webs, but I haven't found an actual number. I assume there would be a fixed cost associated with creating masks and such and then there will be a cost per unit.     Note: that I don't actually want to have an ASIC made, I'm just curious. Can I create a Controller that simply returns an image asset?  I would like to route this logic through a controller, whenever a URL such as the following is requested:  www.mywebsite.com/resource/image/topbanner   The controller will look up topbanner.png and send that image directly back to the client.  I've seen examples of this where you have to create a View - I don't want to use a View. I want to do it all with just the Controller.  Is this possible? Can anyone point me to a reference (preferably either something online or something a small liberal arts school would be likely to have in its library) that goes through a derivation of the minimum uncertainty wavefunction in more detail than in the Griffiths?  Edit I've moved the second part of my original question to a separate post: Java - Splitting a CSV file into an Array Where can I find web design projects? I am a recently graduated graphic designer. I would like to know if there are any worthwhile websites that I could present my portfolio and receive or look for job offers.  I have came across the following freelancewebsites by searching the web that seem to meet my criteria:       (the most famous website for people seeking for employers and employees)   I've also found two articles providing reviews on these types of sites:       I am new to the online freelance market. As a result, I don't have any clue which websites are mainstream for graphic designers and illustrators (which are my specialties). It's not immediately discernible to me which sites are the ones that are not a scam and are also good place for establishing myself.  I'm mainly looking for the resources that experienced designers are familiar with. I'm looking to narrow it down to the ones that have been used by those established in the industry. As a result I decided to consult the matter here and ask for input. Height of an HTML select box (dropdown) Sort and display directory list alphabetically using opendir() in php Favicons in top-bar dropdown not SVG I just bought a new config ( ASUS p8z68-v lx, i5-2500k + ram and new graphic card ). Coming back and installing it in my old computer, I just saw that my DVD player was on IDE (yup…).  So, I needed to install windows 7 64bits from my usb key. Fine, I made my usb key bootable and copy the official DVD on it (the same version that was on my old computer), set BIOS to boot on it first and started the computer up.  It worked fine until it asks me for cd/dvd drivers (which is funny since, I do it via USB because I can't plug in my DVD player :D) I have 3 SATA HDD plugged in and that's it.  I made a small google search and found that it could be SATA or RAID drivers. Fine, I took another USB KEY and put all my motherboard drivers on it (from the CD sold with the MB) and none of those drivers seemed to work. I tried downloading new drivers from ASUS website and same effect.  Any idea but no "buy a new DVD player", I'm now broke for the month :) ? Usage of into vs in vs inside When should 'into', 'in' and 'inside' be used?  What are the differences between the three?   For example, what are the differences between the following statements?  Are any of them incorrect?        The frog jumped into the well.   The frog jumped in the well.   The frog jumped inside the well. Proving $\mathbb{F}_p/\langle f(x)\rangle$ with $f(x)$ irreducible of degree $n$ is a field with $p^n$ elements I am attempting to prove what the title says, that $\mathbb{F}_p/\langle f(x)\rangle$ with $f(x)$ irreducible of degree $n$ is a field with $p^n$ elements.  I have already proven that for any field $K$ and polynomial $f(x)$ in $K[x]$, $K[x]/\langle f(x)\rangle$ is a field if and only if $f(x)$ is irreducible in $K[x]$. So I know that $\mathbb{F}_p/\langle f(x)\rangle$ is a field for sure. Where I'm lost is figuring out how to know for sure that there are $p^n$ elements. It's fairly clear if $n\in\{ 0 ,1\}$, but I don't think induction is going to help.  I know from a proposition in class that since $F_p = \mathbb{Z}/\langle p\rangle$ and $F_p = \mathbb{Z}/\langle p\rangle$ is an integral domain, $F_p[x] = (\mathbb{Z}/\langle p\rangle)[x] = (\mathbb{Z}[x])/(\langle p\rangle[x])$, but I'm not sure whether or not that's helpful information. What was the meaning of the Night King's message? In S08E01 of Game of Thrones, we see this message:    We have seen this several times, the symbol drawn with horse heads, the stones around the Weirwood where White Walkers are created and in some caves, drawn by Children of the Forest.  Do we know the meaning behind this symbol? Does it or something similar occur in the books as well? Auto comment "possible duplicate of ..." missing on voting to close as duplicate Please refer to the following question:    The  had posted an  a while back.  I posted a comment referring to the same and voted to close the question as a duplicate of the referenced question.  Surprisingly, an auto comment saying "possible duplicate of ..." was not generated.  I agree that the referenced question shows up in the linked questions list but an auto comment ought to be generated.  Seems like a bug.    EDIT: I understand that the above behavior is by-design.  However, I'd say that the behavior in the following case should also be the same:  It's interesting to see that the auto comment would be generated if you were to add a comment linking to an answer and then voting to close the question as duplicate.  For example, observe the following question: Watched screen recording but it's not saved to the desktop I recently recorded a session with my dad. I stopped the recording after the session ended (with the setting set to save to Desktop), clicked the icon that appeared on the lower right corner to open the file, and played back a few minutes to make sure it worked. I then clicked Share to send it via AirDrop to my computer, which did not work; the status remained &quot;cancelled&quot; despite my efforts. I assumed I'd be able to access it through my phone by sending it through a third app, so I pressed cancel on the AirDrop pop-up window. The entire screen recording closed and (apparently) vanished forever after the action. I'm extremely frustrated because I can't seem to locate this video.
