How do I interpret the statistics of a memtest run?
I have a notebook here that I suspect has a faulty memory module. I therefore downloaded Memtest86+ and let it run. Note that the screenshot is not my actual one, it's provided by memtest86+ How do I interpret the numbers on the screen? I've let it run for about four hours and now I'm in pass 7. Especially, what does the test number the count of Errors the count of ECC errors indicate? What are sane values for memory errors? At which point should I consider replacing memory?
How can I own an IP address?
How can I own an IP address like I do with domains? I have done some research and it seems that you can't buy a single IP, but rather you have to purchase a range of IP addresses. Update : Important Note I want this IP to use it with my servers. for example I had a VPS, it went bad, I want to be able to use the same IP on another VPS from another company.
Command prompt hangs until keypress?
Problem: For some reason once in a while my command prompt would hang until I press a random key, and it would continue operation as if nothing happened. Occurrence: This happens when I am running a long operation (such as building/compiling some code). When it hangs, it gives no indication of what's going on nor does it prompt me to press any key. Description: After a couple minutes, the terminal stops printing out the progress, and gets stuck. I had thought that it was simply stuck on a very lengthy portion of the compile process, but after a few hours it was still stuck on the exact same place. I pressed a random key, and it suddenly jumped straight back and continued spewing out progress indicators and continued working. After this, similar events have happened many times during lengthy processes, such as copying files. This has happened on multiple devices running windows 7. It has also occurred on Ubuntu using bash shell.
What do I need to consider when buying hardware to meet my needs?
I'm looking to build a new computer from the ground up. I'm not sure what to look out for and need guidance and help on how to pick the hardware needed to construct my new rig. How do I know what to buy? How do I find out if a given CPU will be enough for a certain game or application that I want to run? How do I find out if a given graphics card will be enough for a certain game or application? What is important when looking at motherboards? How much memory do I need? How do I know how much wattage I need for a power supply? What size case do I need? What relevant standards do I need to read up on and be aware of? PCI, PCIe, SATA, USB 2.0, USB 3.0, etc... What "gotchas" do I need to be on the lookout for? Please keep responses generation-agnostic to ensure they will be helpful to our future users. While Stack Exchange does not permit shopping recommendations, it doesn't provide any general advice to consider when buying hardware. So, instead of just telling those that ask what to buy…
Restoring performance and estimating life of a used SSD drive?
My old 128 GB SSD drive is about a year and a half old now, and I've since upgraded to another drive. I'd like to clean up my the old SSD to ... restore its performance to near-new levels rehabilitate it and generally give it a health check How do I go about doing this?
Suck or blow? What's better for dust?
The guy at the local PC hardware store told me it's better to use a small hand-held leaf blower to blow dust out of your PC case than a hand-held vacuum cleaner. Why is this? I understand that fans might be damaged if they "spin too fast", but surely this is a problem with both vacuuming and blowing dust away... I imagine both machines would generate a small amount of static to be discharged carefully, so I can't see how one would be "safer" than the other?

Installer hangs on "waiting for other installations to finish" despite no other installations in progress
I started an installation of the Xcode 4 developer's preview last night before going to bed. When I woke up, the installation had popped up a message saying to close Xcode first (doh!). I did so, but whatever script had displayed the message seemed to have hung because the (uncancellable) message wouldn't disappear, and the installer wouldn't progress. After force quitting the Installer app, the message above was still showing, so I restarted my MacBook Pro and then tried the installation again. This time it wouldn't even start, instead showing one of those candy-stripe activity bars and the message: Waiting for other installations to finish At this point, I'm stumped. There are no other installations in progress, so there must be some artifact left over from the interrupted install that's gumming up the works. But what?
Is it possible to sum an entire column without setting explicit cell boundaries in Excel?
I'd like to sum all the values in a column starting from a certain minimum value, but I don't want to give an upper bound because any value in the table will be appropriate for summing (minus the header of course) and I'd like to do it the "right" way instead of summing . Is this possible?
Which special variables are available when writing a shell command for a context menu
When extending the Windows' shell context menu (e.g. for adding an 'Open command here' prompt on directories), a 'command' key needs to be created in the registry. The value of this 'command' key apparently can be any valid command line. I want to know which 'special variables' are available for use inside this command line. For example, I use following command for opening a cmd window from within a directory's context menu (*): I cannot find any reference to what actually means or what the full list of such variables is. (*) Following registry keys are created for this:
Switching to tabs to the right or left of the current tab in Notepad++
How can I switch to the document to the left or right of the current document in Notepad++? For example, if I have documents , , and open, and I'm currently editing , I would like a shortcut to be able to: switch to document , like. . . (Alt-LeftArrow or Ctrl-Pageup) OR switch to document , like. . . (Alt-RightArrow or Ctrl-PageDown). All I've found is a way to switch to next or previous documents based on the "history" of when the document was last opened, for example: (Ctrl-Tab and Ctrl-Shift-Tab) The examples I have found are useful, but not what I want. Is what I am asking for possible?
Is there a way to copy URLs from all open tabs in a Google Chrome (or other browser) window into an email?
Are there any Google Chrome extensions that would allow you to copy the URLs of all open tabs into the clipboard, or even better, to send them to a new Gmail message? My personal scenario is house hunting, opening many prospective places in separate tabs, and then wanting to send a message with all the links without copying and pasting each URL.
Avoid unwanted path in Zip file
I'm making a shell script to package some files. I'm zipping a directory like this: The problem is that the resultant out.zip archive has the entire file path in it. That is, when unzipped, it will have the whole "/Users/me/development/anotherthing/" path in it. Is it possible to avoid these deep paths when putting a directory into an archive? When I run zip from inside the target directory, I don't have this problem. In this case, I don't get all the junk. However, the script in question will be called from wherever. FWIW, I'm using bash on Mac OS X 10.6.
Which Debian package architecture am I using?
What's the command to find out which Debian package architecture I'm using? eg, on a 64 bit x86, I'm expecting something like , on 32 bit x86 and from OSX 10.6 (via Fink).
Correct way to disable indexing in Windows 7
What's the best way to disable indexing in Windows 7? All of the articles that I've found online instruct me to access services.msc and disable the Windows Search service. However, even after I did that, when I right click properties of my C-drive, I notice the "Allow files on this drive...indexed..." is still checked. So should I uncheck that option and re-enable Windows Search? Or just uncheck it and leave the Windows Search service disabled?
How do I edit an existing buffer in a new tab in vim?
Suppose I have started vim like this: Now I decide that I want each of those files in its own tab. Is there a way to do that without exiting vim and adding the option to my command line?
How can I merge the gnome clipboard and the X selection?
I'm constantly frustrated by the two separate clipboards in X/Gnome. I'm constantly doing things like control-C to copy, and then middle-click to paste, and getting the wrong data. Or select something, then go where I want to paste it, and selecting what I want to paste over, only to lose my first selection! Is there any way to merge these two clipboards? Update: Parcellite comes close, but pasting over a selection is really essential. Is there a way to disable select-as-copy in X?
How do I uninstall any Apple pkg Package file?
Despite opinions to the contrary, not all packages are installed cleanly in only one directory. Is there a way to reverse the install process of a pkg file, preferably with the original package (or from a repository of information about installed packages)? Specifically I've installed the PowerPC MySQL 5.4.1 package on an intel MacBook, and would like to cleanly reverse that, recovering the 5.1 x86 install I can see is still there, but not working properly now.
How to view Internet Explorer auto-detected proxy settings?

Force-refreshing only JavaScript files in Firefox and Chrome
I want to clear only JavaScript files from my web browsers (Firefox and Chrome). I am doing JavaScript debugging, and it's annoying that my JS just won't get updated whenever I change my JS files. The only thing I can do now is to clear my cookies, but doing that erases all of my browsing history. How can I clear/refresh the JavaScript files that have been loaded into my browsers without clearing out other files?
