• Slight stuttering when moving windows in fresh 12.04 install

  - by Konsolkongen

  Installed Ubuntu 12.04 today and my problem is that when I'm moving the windows around my screen it doesn't feel smooth at all. Usually I can fix this by changing the refresh rate to 60Hz, but this time it doesn't help. My graphics card is a Nvidia GTX 560Ti and I've tried both the 295.40, 295.45 and 304.43 (which I'm currently using) but neither has resolved my problem. I searched around a bit and tried changing the refresh-rate using compizconfig-settings-manager and xrandr. No change using CCSM, but when I tried xrandr I got this reply: konsolkongen@konsolkongen-desktop:~$ xrandr -r 60Rate 60.0 Hz not available for this size - which is nonsense of course. This is what my xorg.conf file looks like: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@allspice) Fri Mar 30 15:25:24 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "Samsung SyncMaster" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 560 Ti" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "metamodes" "DFP-0: 1680x1050_60 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Any help would be greatly appreciated, my obsession with video quality can't stand stuttering like this. For what it's worth though, I don't have any screen tearing, so at least V-sync is on. Thanks.

• Prevent Nautilus from displaying thumbnails on a specific mount

  - by Zakhar

  I have written a filesystem over Fuse to access a remote pseudo-NAS (the French "Freebox V6", I'll soon publish it as GPL3... when it's a little bit more polished!). The NAS is connected to a home ADSL, thus data comes down at the upload speed of ADSL, which is at best 1Mbps. My mount works fine (read-only at the moment), but Nautilus sees the mountpoint (and all sub-directories) as a "local" filesystem and tries to make thumbnails. As I have a directory full of images, this is quite horrible, because Nautilus then opens ALL the images to try to display the thumbnail. I could switch the Nautilus preferences to "Never" for thumbnails, but then I'll loose thumbnails on my "real" local filesystem. So the question is: with the preference "Only for local filesystem", how can I instruct Nautilus that my mountpoint is in fact NOT a local mount so that it will stop trying to draw thumbnails on that specific mount, but continue "thumbnailing" on mounts that are really local? Edit note: the same things happens if you use "standard worldwide" mounts such as sshfs, davfs,... as long as you mount over a relatively slow network (ADSL) and have images/movies on your mounted tree.

• htaccess: how to rewrite to clean urls and redirect old urls to the new clean ones?

  - by Sebastian

  With htaccess I'm trying to make my sites urls clean. I use very basic urls like: www.mysite.com/pagename.php ("pagename" is variable). I want www.mysite.com/pagename to display the content of /pagename.php So this is in my htaccess-file now: Options +FollowSymlinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^([^\.]+)$ $1.php [NC,L] But I also want my old urls (/pagename.php), when called, to be rewritten to www.mysite.com/pagename How to do this? I can't figure it out (get loops all the time)... Thanks in advance!

• Exclude pings from apache error logs (ran from PHP exec)

  - by fooraide

  Now, for a number of reasons I need to ping several hosts on a regular basis for a dashboard display. I use this PHP function to do it: function PingHost($strIpAddr) { exec(escapeshellcmd('ping -q -W 1 -c 1 '.$strIpAddr), $dataresult, $returnvar); if (substr($dataresult[4],0,3) == "rtt") { //We got a ping result, lets parse it. $arr = explode("/",$dataresult[4]); return ereg_replace(" ms","",$arr[4]); } elseif (substr($dataresult[3],35,16) == "100% packet loss") { //Host is down! return "Down"; } elseif ($returnvar == "2") { return "No DNS"; } } The problem is that whenever there is an unknown host, I will get an error logged to my apache error log (/var/log/apache/error.log). How would I go about disabling logs for this particular function ? Disabling logs in the vhost is not an option since logs for that vhost are relevant, just not the pings. Thanks,

• How do I get a different type of scrollbars in 12.04? [closed]

  - by Joseph Garvin

  Possible Duplicate: How do I disable overlay scrollbars? By default 12.04 uses overlay scroll bars that do not suit my taste, and every method I've found so far of disabling them makes them broken in a different way. When I was using 11.10 this wasn't a problem because I could still change the GTK theme. In 12.04, the Appearance settings only contain a few stock themes, and other than the special purpose contrast ones they all have the overlay scroll bars. If I aptitude search gtk3 | grep theme I get no results so there appears to be no packaged alternative either. Most suggestions I've seen for disabling the overlay scroll bars involve uninstalling packages or editing files as root. I want to disable them just for the current user, not for everyone on the whole box; as should be the case for any theme/display setting. There is a gsettings command that temporarily disables the overlay scrollbars just for the current user, but this has two problems of its own: The setting doesn't stick after log off. Because who would want to save settings? The scroll bars put in place have no contrast. They have a black scroller on a black background and are completely unusable. In short what I'd like to know is how to disable overlay scroll bars such that: My preference is user specific. My preference is actually saved. The scroller can actually be seen against the background without having to use a special high contrast theme that makes my whole desktop look like a negative photo from Tron.

• Applescript create event in calendar, how do I remove the default alert?

  - by zero0cool

  Running 10.8 Mountain Lion, I'm trying to create a new event with Applescript like this: set theDate to (current date) tell application "Calendar" tell calendar "Calendar" set timeString to time string of theDate set newEvent to make new event at end with properties {description:"Last Backup", summary:"Last Backup " & timeString, location:"To a local unix system", start date:theDate, end date:theDate + 15 * minutes, allday event:false, status:confirmed} tell newEvent delete every display alarm delete every sound alarm delete every mail alarm delete every open file alarm end tell end tell end tell However, this does not remove the default Calendar alert which one can set through Calendar preferences (30 minutes prior in my case). How do I create an event with no alarms at all through Applescript?

• wordpress makes duplicate images of different size

  - by Mark

  I have a wordpress website. I upload my pictures to the media library. And when I import a picture in a post, you get the options, one of which ask you what size to display it in. And doing this results in creating a new image file that is a different size, rather than wordpress using html to control the size of the image. The following image shows how different sized picture copies are made of the same one with different resolution. http://imgur.com/uVqTN Thank you everyone in advance.

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• How can I view my video card's temperature via SSH?

  - by NT3RP

  I've finally managed to set up my two ATI Radeon 6950 video cards in my machine, but the cards can get quite hot. Based on the arrangement of my apartment, I want to be able to SSH into the machine an execute a command to find out the temperature. What I have tried so far is this... export DISPLAY=:0.0 sudo aticonfig --adapter=0 --od-gettemperature However, when I do that via SSH, I get the following error: ERROR - X needs to be running to perform ATI Overdrive(TM) commands If I turn on X forwarding when I remote into the machine, then it just seems to affect my local machine instead of the remote machine. Am I doing this correctly? Is there a better way to monitor my video card's temperature?

• Is there a way to catch cmd.exe windows into tabs?

  - by user55542

  I use an editor that allows me to type in a command to run. In order to see the output without having to redirect it to a file, I precede the command with "cmd /k," which leaves an open cmd.exe window. So I'd like to find a way to move catch the call to cmd.exe and give it to an application that tabifies cmd.exe, a terminal emulator as it's called. The desired result would be similar to what happens in a tabbed editor, when that editor is to open some file, it does so in another tab, and not in another window. While in a given situation it may be easier to modify the command to redirect output to display in the editor itself, in general it would be more helpful if I could find a way to catch all such calls into one window.

• How to include a non-breaking hyphen in hyperlink text in Word 2010

  - by dunxd

  I want to include a URL in word document, both as text people can read, and a link they can click. The URL has a hyphen in it. I don't want the URL to get broken across lines. When I use a regular hyphen, the link works, but the text displayed gets broken. When I use a non-breaking hyphen (Ctrl+Shift+-) Word removes the hyphen from the link. When I try and manually edit the hyperlink, I can't add a non-breaking hyphen into the Text to display field using Ctrl+Shift+-. If I was writing this is HTML I could just do: <a href="http://www.my-link.com/">www.my&#8209;link.com</a> How do I get Word to do the equivalent?

• Java game design question (graphical objects)

  - by vemalsar

  Hello Guys, I'm beginner in game development, in Java and here on this site too and I have a game design question. Please comment my idea: I have a main loop which call update and draw method. I want to use an ArrayList which store graphical objects, they have coordinate and image or text to draw and my game objects extends this class. In update, I can choose which objects should be put in the array and in draw method I'll display the elements of array on the screen. I'm using a buffer and draw first there, but it is not important now I guess...Here is a simple (not full) code, only the logic: public class GamePanel extends JPanel implements KeyListener { ArrayList<graphicalObjects> graphArray = new ArrayList<graphicalObjects>(); public void update() { //change the game scene, update the graphArray, process input etc. } public void draw() { //draws every element of graphArray to a JPanel } public static main(String[] args) { while(true) { update(); draw(); } } } My questions: Should have I use interface or abstract class for graphicalObjects? graphicalObjects class and the ArrayList really needs or there is some better solution? How to draw objects? They draw themself with their own method or in the draw method I have to draw manually based on graphicalObjects variables (x,y coordinates, image etc.)? If this conception is wrong, please suggest another one! All comments are welcome and sorry if this is dumb question, thanks!

• What software can I use to get statistics about the programs I use most? [closed]

  - by pinouchon

  I am looking for software that reports statistics about my program usage over time. It should display output something like this (numbers are made up): Program usage today: Youtube (Chrome) 42:10 9.42% NetBeans 30:52 6.33% Google search (Chrome) 12:03 3.20% Windows explorer 5:43 1.54% Putty 2:23 0.89% ? ? ? Features I look for: Advanced statistics: ability to view a chart, to see statistics today, this week, this month. Program usage should be based on the title of the active window. The time where the user is idle shouldn't count. Ability to group some windows title together, for example, I want to group titles as Stack Overflow and * - Stack Overflow together, same thing for every website and explorer windows. Do you know a program that does something similar?

• Why is the Python interpreter provided by Django suddenly showing me Python tab completion upon a single Tab press?

  - by ysim

  This issue seems to have just started happening; basically I just noticed that whenever I press the Tab key in the Python interpreter that comes with Django, it gives me the Display all ... possibilities? (y or no) prompt. I opened a similar question just now, where I noticed that removing set show-all-if-ambiguous on from .inputrc fixed the problem in the non-Django Python interpreter that was showing me bash tab completion, but the problem persists with the Django one, only with Python tab completion. It's very odd and it seems to have come out of nowhere. There's nothing else in my .inputrc other than set completion-ignore-case on, which shouldn't be conflicting with the Python interpreter, but I've also tried removing that (leaving my .inputrc blank), but it's still happening. I'm not sure why this is suddenly happening, but it would be great if someone had an idea of why and how to fix it.

• Sharepoint .PDF contents displaying as 'searchtext.xml' in searches

  - by Green Muffins

  Hi Experts, I recently used installed ifilter in my sharepoint farm to enable searching of the contents of .pdf documents. All went well, except if I search for contents of any .pdf file, they appear in the search results with document title "searchtext.xml", and the link to the document gives a giant page of the .pdf contents in an .xml looking browser page. :s I have added .pdf filetypes to the search, so I am unsure why it is reading them incorrectly.. if I search for a .pdf document title such as 'document.pdf' it will display the result as a html page, though the link does follow to a readable .pdf file. Any help?

• How do I show some simple HTML (text/images) in the sidebar of my Drupal 7 theme?

  - by shady

  I've created a theme using Zen and all is well. I want to display some simple text and images in the sidebar, but I don't understand Drupal well enough to know what I'm doing. I have worked with Joomla which allows one to create a new HTML module, populate it, and then select where it appears on the page (and also of course which pages). I don't see this with Drupal. I've seen some talk about using the theme's templates, but I need for my client to be able to change the text (and/or images) without knowing anything about that. It would be best to create an article and be able to make that article appear in the side bar somehow. Is this possible?

• HTML Manifest for Content Folios

  - by Kyle Hatlestad

  I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. I thought this might be useful for others, so I'm posting a copy of the component here. Beyond the standard instructions for installing a component, there is an environment configuration file (folionativezipwithmanifestrenderer_environment.cfg) which has a couple of options. FolioMetadataManifestList - This is a comma separated list of metadata fields (system or custom) that should be included in the manifest file. FolioMetadataManifestUseOriginalFilename - (True or False) If set to True, the filenames in the zip file will be based on the original filename as it was checked into WebCenter Content.  If False, it will use the 'Name' of the item as defined within the Folio.  This is usually the Title of the item. The component also includes the source code, so feel free to use this as a reference for creating other interesting folios.

• MS Clear Screen Saver doesn't work

  - by ufoq

  I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

• Creating movement path displays in a top-down 2d RTS

  - by nihohit

  My game is a top-down 2d RTS coded in C# using SFML's libraries. I want that during unit selection, a unit will display it's movement path on the map. Currently, after the path is computed as a list of directions ({left, up,down, down, down, left}, as an example), it's sent to the graphical component to create it's UI equivalent, and here I'm having some problems. current, these I've checked three ways to do it: compute the size of the image (in the example above it'll be a 3*2 rectangle) and create an invisible rectangle, and then go over the directions list and mark each spot with a visible point, so as to get a continous line. This system is slightly problematic because of the amount of large images that I need to save, but mostly because I have a lot of fine detail onscreen, and a continous line obstructs the view. again, compute the size of the image, but now create several (let's say 4) invisible images of that size, and then instead of a single continous line I'll switch between the four images, in each will appear only a fourth of the spots, in a way which creates a path animation. This is nicer on the eye, but here the memory demands, and the amount of time needed to compute each such image-loop is significant. Just create a list of single markers, each on a different spot on the path. This is very quick & easy on memory, but too sparse. Is there a simple or resource-light system to create path-animations?

• How to find hidden/cloak files in Windows 2003?

  - by homemdelata

  Here is the point. I set Windows to display all the hidden files and protected operating system files but even after that, my antivirus (Kaspersky) is still getting a ".dll" file on "c:\windows\system32" saying it's a riskware 'Hidden.Object'. I tried to find this file everytime but it's not there. So I asked one of the developers to create a service that verifies the folder each 5 seconds and, if it founds the file, copies to another place. After a lot of research I just found out that every file with this same name on this specific server gets cloak, doesn't matter the file extension. How can I found this kind of file? How can I "uncloak" it? How can I know what this file is doing?

• Is there a piece of software which lets you turn "anything" into a dynamic reorderable list?

  - by Robin Green

  I could write this myself, but I want to know if it already exists. Basically, it must fulfill these criteria: To reorder items, the user must never have to manually renumber them. That would be annoying, and it doesn't scale. Can read from a range of data sources (e.g. a database, a directory on the file system, a text file, another list) When the original data source changes, the list must automatically change with it (possibly with confirmation, e.g. if a list item would be deleted) Ability to persist the list ordering in some fashion Graphical display of list items (so that they can include e.g. images) Optional extras: Ability to modify data and write back to the data source (other than the ordering information)

• How to disable Empty Recycle Bin confirmation dialog?

  - by kjo

  In Windows 7 (at least) when one chooses Empty Recycle Bin from the RB menu, one gets prompted with a dialog like: Are you sure you want to permanently delete these 11 items? (modulo the actual number of items mentioned). Is there a way to disable this dialog (without disabling the use of the RB altogether)? NOTE 1: This dialog comes up even if one has unchecked the box labeled "Display delete confirmation dialog" in the RB Properties dialog (as long as the RB has not been disabled). NOTE 2: As alluded to above, any answer that entails disabling the use of the Recycle Bin altogether is explicitly ruled out. This includes any answer that involves selecting the button labeled "Don't move files to the Recycle Bin. Remove files immediately when deleted." in the RB Preferences window. NOTE 3: This question has nothing to do with Outlook Express.

• Determine compression ratio for Windows compressed drive

  - by munrobasher

  Is there a Windows 7 native way to display the overall compression ratio on a Windows compressed drive? As part of our disaster recovery process, we're copying some key system folders onto 2TB external hard drive, encrypted using TrueCrypt and copied using robocopy. The drive is compressed and I'd like to see what kind of compression ratio we're getting and whether it's actually worth the performance overhead. I know that TreeSize can possibly do this (as mentioned in another post) but want a OS native way if possible. Thanks, Rob.

• Firefox Wordwrap

  - by AtlantaBill

  The text displayed in several, forum sites that I frequently visit does not automatically word wrap in Firefox's window. Rather, it just "runs off" the right end of the window. I can cause the text to properly word-wrap by maximizing the window and then immediately returning it to its normal size. This lasts until I move to another page and then I have to repeat this "work-around" to display word-wrapped text properly again. Anyone have any ideas on what I can do to make Firefox always automatically word-wrap text? TIA. Bill
