  • How to recover from terminal custom setup

    - by linq
    I installed ubuntu 12.04 and I added "Terminal" to the launcher bar, the default size of the terminal is a bit small, after some googling here is how I made the disaster change: At HUD menu, type "preference" and I see the option of Edit > preference, this is as I expected After I clicked the option, I forget the exact steps, but somehow I came to some configuration panel and there is a checkbox for terminal "custom" and I checked it now an input box is enabled and I type gnome-terminal --geometry 160x50 Now the problem comes, whenever I click the terminal button at the launcher bar, new terminal windows pops up endlessly from everywhere, I cannot do anything any more except logout or shutdown. The weird thing is, after I come back, I cannot get that Edit > preference any more when I type "preference" in HUD, I tried "Edit", "preference". To be clear, I still can use the computer as long as I do not click that terminal button, but I really want to use terminal to run commands. Help is appreciated greatly! Update - OK, figured out. Go to /home/jibin/.gconf/apps/gnome-terminal/profiles/Default and open that xml file, I can see the options I changed at the GUI, remove them and terminal runs good. The preference HUD is back also, it is actually Profile Preference and it is only available when terminal is open. Continue my ubuntu-ing...

  • How to create iso dvd image for use with Mac OS X's "Disk Utility"?

    - by adolf garlic
    This seemed way easier on my pc. I would just pop a blank dvd in the drive, it asked what I wanted to do with it, to which I would respond, "burn dvd with nero" (paraphrasing), then I would pick "new" and just drag and drop the folders in there. Mac appears to have "Disk Utility" which just requires that I 'choose an image' but then doesn't bother to detail: how to do this what the options mean e.g. format "Mac OS Extended (Journaled)" is that ever going to be readable on a non Mac machine? I want to create an ISO standard DVD as per the 'default' you'd get on nero. All the stuff on the web points to doing things with 'Terminal' (the whole point of buying a Mac was to get away from command line jiggery pokery - I'm trying to burn some photos not land a friggin lunar module here!) Please, if you can just provide some simple instructions on what I need to achive this I'd be extremely grateful. Ta muchley in advance.

  • Can windows XP be better than any Ubuntu (and Linux) distro for an old PC?

    - by Robert Vila
    The old laptop is a Toshiba 1800-100: CPU: Intel Celeron 800h Ram 128 MB (works ok) HDD: 15GB (works ok) Graphics adapter: Integrated 64-bit AGP graphics accelerator, BitBIT, 3D graphic acceleration, 8 MB Video RAM Only WindowsXP is installed, and works ok: it can be used, but it is slow (and hateful). I thought that I could improve performance (and its look) easily, since it is an old PC (drivers and everything known for years...) by installing a light Linux distro. So, I decided to install a light or customized Ubuntu distro, or Ubuntu/Debian derivative, but haven't been successful with any; not even booting LiveCDs: not even AntiX, not even Puppy. Lubuntu wiki says that it won't work because the last to releases need more ram (and some blogs say much more cpu -even core duo for new Lubuntu!-), let alone Xubuntu. The problems I have faced are: 1.There are thousands of pages talking about the same 10/15 lightweight distros, and saying more or less the same things, but NONE talks about a simple thing as to how should the RAM/swap-partition proportion be for this kind of installations. NONE! 2.Loading the LiveCD I have tried several different boot options (don't understand much about this and there's ALWAYS a line of explanation missing) and never receive error messages. Booting just stops at different stages but often seems to stop just when the X server is going to start. I am able to boot to command line. 3.I ignore whether the problem is ram size or a problem with the graphics driver (which surprises me because it is a well known brand and line of computers). So I don't know if doing a partition with a swap partition would help booting the LiveCD. 4.I would like to try the graphical interface with the LiveCD before installing. If doing the swap partition for this purpose would help. How can I do the partition? I tried to use Boot Rescue CD, but it advises me against continuing forward. I would appreciate any ideas as regards these questions. Thank you

  • How to use Client for NFS on Windows Vista?

    - by netvope
    I've installed "Client for NFS" on my 32-bit Windows Vista Ultimate. However, I can't find it in the start menu, and can't find any documentation on how to use it. How do I connect to a NFS share using "Client for NFS"? Can I map it to a drive letter? How do I choose connection options, such as my uid/gid, mount as read-only, port number, etc? Ideally I would like to map a NFS share using the command line. You may also suggest alternatives to "Client for NFS".

  • Which one is better offline method for large scale application

    - by Manish Pansiniya
    We've a big data management website used by several property. Some of our customers have downtime (they can't access net for an hour or two). We want our site to support offline data viewing and inventory management (typical data search and add/remove) and when the user goes online we can sync the changes back to our central database. Customers use several platforms like Windows, iOS, etc. We've been looking into several different options, here are the major choices - Develop offline web app supported in HTML5. Develop a 'fallback' mechanism and interact with data from the app cache as explained in here (http://www.htmlgoodies.com/html5/tutorials/introduction-to-offline-web- applications-using-) Develop a desktop based cross platform solution. I remember the old MONO which has been popular. Here's a post (What do you suggest for cross platform apps, including web cross-platform-apps-including-web) and another one (Technology choice for cross platform development (desktop and phone)? platform-development-desktop-and-phone?rq=1) I realize the the desktop solution might be hard to maintain and result in some compatibility issues and demand test environments. Can HTML5 handle moderate to high level complexity and data flow? Or would it be better to rely on a desktop based app for better scalability & performance?

  • Is it possible to rent a virtual instance of Windows/XP/Vista/7 in the cloud on pay as you go basis?

    - by Janusz
    I am a software developer and I need to test my software on different OS all the time. I am using free VPC images from IE6 compat kit from Microsoft but they have only limited options of Windows Versions (Win XP SP3 and some restricted version of Vista). I need a service where I could rent a Virtual OS in the cloud and connect via Remote Dektop. Use for couple of hours and then discard all the stuff I have been doing there. I tried using Amazon S3 but they only have Windows Server 2003 Anyone knows of such a service that would offer different XP/Vista/7 versions ?

  • Meta key in Terminal.app vs national characters

    - by yacoob
    I'm using Terminal.app, and I'd like to use emacs running inside - either locally, or after sshing to remote server. Problem is, I can't get working Meta modifier. Namely, if I enable 'Use option as meta key', Option key works like proper Meta, but I lose ability to enter Polish diacritics (aelósznzc), that are entered with right Option. If I disable 'Use option as meta key', my Meta is gone, but I can again use Polish characters. In this state they appear only with right Option modifier, so I guess it's Terminal.app's fault that it doesn't make a difference between left and right Option key, when the relevant preference is selected. What are my options then? Is there a good solution for my problem? I can always use ESC as a poor man's Meta replacement, but I don't like that idea.

  • Self-referencing anonymous closures: is JavaScript incomplete?

    - by Tom Auger
    Does the fact that anonymous self-referencing function closures are so prevelant in JavaScript suggest that JavaScript is an incomplete specification? We see so much of this: (function () { /* do cool stuff */ })(); and I suppose everything is a matter of taste, but does this not look like a kludge, when all you want is a private namespace? Couldn't JavaScript implement packages and proper classes? Compare to ActionScript 3, also based on EMACScript, where you get package com.tomauger { import bar; class Foo { public function Foo(){ // etc... } public function show(){ // show stuff } public function hide(){ // hide stuff } // etc... } } Contrast to the convolutions we perform in JavaScript (this, from the jQuery plugin authoring documentation): (function( $ ){ var methods = { init : function( options ) { // THIS }, show : function( ) { // IS }, hide : function( ) { // GOOD }, update : function( content ) { // !!! } }; $.fn.tooltip = function( method ) { // Method calling logic if ( methods[method] ) { return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 )); } else if ( typeof method === 'object' || ! method ) { return methods.init.apply( this, arguments ); } else { $.error( 'Method ' + method + ' does not exist on jQuery.tooltip' ); } }; })( jQuery ); I appreciate that this question could easily degenerate into a rant about preferences and programming styles, but I'm actually very curious to hear how you seasoned programmers feel about this and whether it feels natural, like learning different idiosyncrasies of a new language, or kludgy, like a workaround to some basic programming language components that are just not implemented?

  • Coarse Collision Detection in highly dynamic environment

    - by Millianz
    I'm currently working a 3D space game with A LOT of dynamic objects that are all moving (there is pretty much no static environment). I have the collision detection and resolution working just fine, but I am now trying to optimize the collision detection (which is currently O(N^2) -- linear search). I thought about multiple options, a bounding volume hierarchy, a Binary Spatial Partitioning tree, an Octree or a Grid. I however need some help with deciding what's best for my situation. A grid seems unfeasible simply due to the space requirements and cache coherence problems. Since everything is so dynamic however, it seems to be that trees aren't ideal either, since they would have to be completely rebuilt every frame. I must admit I never implemented a physics engine that required spatial partitioning, do I indeed need to rebuild the tree every frame (assuming that everything is constantly moving) or can I update the trees after integrating? Advice is much appreciated - to give some more background: You're flying a space ship in an asteroid field, and there are lots and lots of asteroids and some enemy ships, all of which shoot bullets. EDIT: I came across the "Sweep an Prune" algorithm, which seems like the right thing for my purposes. It appears like the right mixture of fast building of the data structures involved and detailed enough partitioning. This is the best resource I can find: http://www.codercorner.com/SAP.pdf If anyone has any suggestions whether or not I'm going in the right direction, please let me know.

  • idle proccesses and high memory bad? uwsgi/django

    - by JimJimThe3rd
    I have a VPS with 256MB of ram. I'm running nginx, uwsgi and postgresql on Ubuntu 12.04 for a soon to be Django site. About 200MB of ram are being used despite the website not being active, the uwsgi processes seem to just be idling. Is this bad? I once heard that having a bunch of free memory isn't necessarily a good metric because it is possible that the memory in use can easily be freed up. I mean, it is possible that the server is storing commonly used "stuff" in case it is accessed but is more than happy to dump it if the ram is needed. But I'm really not sure, hence me asking this question. If it is bad I could set some of the application loading options for uwsgi like "cheap" or "idle" mode. Screenshot of my htop

  • Creating stereo file from two mono files with sox

    - by haimg
    I'm using sox 14.2.0 on Centos 6.0. I have two mono wav files, left.wav and right.wav. I need to combine them into one stereo.ogg file, with left.wav pan 80% to the left, and right.wav pan 80% to the right. I was unable to come up with the sox options needed for this. How do I do this? This is going to be executed repeatably for many files, so I'd prefer an efficient solution. From what I understand there should be a way to do it in one pass (one invocation of sox).

  • How to create or recover Windows Bootloader after deleting Ubuntu boot drive

    - by Kincaid
    I have a computer that dual-boots (or tri-boots) Windows 8 Release Preview, Windows 7, and Ubuntu 12.04. Grub boots between Windows 8 and Ubuntu; for which I use primarily. Recently, I decided to remove Ubuntu, as I hardly used it. I deleted the Ubuntu partition accidentally before replacing the Grub bootloader. Now, whenever I want to boot the machine, it gives me the "grub-rescue" prompt -- I am unable to boot into either Windows (8 nor 7), nor Ubuntu (except via USB, of course). I do not have any Windows 7/8 recovery media, so that isn't an option. Please note that after I deleted the Ubuntu partition, I put the PC into hibernate, and then turned it on. This means the C:\ [Windows 8] drive cannot be mounted. I don't know if that is bad, but it definitely doesn't make things better. I am currently booting Ubuntu via USB, in an effort to restore the Windows bootloader. I have looked into using boot-repair to solve the problem using the instructions here, although after attempting to apply the changes, it gave the error: "Please install the [mbr] packages. Then try again." I don't know why I'm getting this error; is there a way to install the 'mbr packages?' I honestly don't know what exactly they are, nor how to install them. Are there any other options I have not yet exhausted to be able to boot back into Windows, in the case that there is a better way? I want to set the bootloader to boot into Windows 8, but booting into either Windows 7 or 8 is fine (I can use EasyBCD from there). Is there a simple solution to this? I've checked BIOS, and I haven't been able to find a way to boot into Windows.

  • Apache Reverse Proxy server and SSL NTLM SharePoint

    - by user50211
    Hi, I'm trying to set Apache as proxy server to an internal SharePoint server. I have previously configured Apache to run as a proxy server to export internal webpages and web applications. However, the Sharepoint is using SSL and NTLM authentication, and this is new to me :( I have tried many options, the traffic seems to be forwared as I get the authentication popup window, but when I insert the user/pass, I get back to the same popup window. Anybody has configured Apache to do so? Here is a part of my httpd.conf: <VirtualHost *:443> ServerName repository.out.com SSLProxyEngine On RequestHeader set Front-End-Https "On" ProxyRequests Off ProxyPreserveHost On ProxyPass / https://sharepoint.in.com ProxyPassReverse / https://sharepoint.in.com CacheDisable * SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 ErrorLog logs/jlanza_log CustomLog logs/jlanza_log common </VirtualHost>

  • Cannot install Windows 8 Transformation Pack on Windows 7

    - by Mehper C. Palavuzlar
    I am trying to install Windows 8 Transformation Pack v4.0 on my Sony Vaio laptop with the following options: When I run (as administrator) the setup file, it starts to install but gives the following error at some point: The file 'C:\Windows\Fonts\segoui.ttf' could not be opened. Please check that your disk is not full and that you have access to the destination directory. Since I run the installer as administrator, this error message seems strange to me. Segoe UI font is also installed on my PC. When I try to install with default system fonts (without Segoe UI), it gives the same error again: What should I do to solve this problem?

  • How do I enable LastPass (or any other browser add-on) for a pinned site in Internet Exploer 9, 10, or 11?

    - by rob
    I use LastPass for several websites, and in all my browsers I can enable the LastPass toolbar to simplify logging into a website: I also have some pinned sites in IE11. When I open a pinned site all the third-party toolbars, including LastPass, seem to be disabled and hidden from the options: As you can see in the following screenshot, LastPass is installed and enabled for both 32-bit and 64-bit IE: I've observed the same problem in IE9 and IE10 on Windows 7 and in IE11 on Windows 8.1. In all cases, I'm running the default IE on 64-bit Windows. How do I enable the LastPass toolbar for a pinned site?

  • Socket.io v.9 with Actionscript

    - by funseiki
    I'm attempting to develop an online multiplayer game using Node.js for the server and Flash to display the client. I've been reading up a bit and have found quite a few recommendations for the socket.io library. I've also found a github project which exposes code to help facilitate communication between an Actionscript 3.0 client and a server using socket.io. The project I mentioned is a bit dated and doesn't seem to have support for the latest version of socket.io, so I was wondering if leveraging this framework (socket.io, that is) would be the most ideal way to go. I have found a simple project that uses the standard 'net' module for node.js, but because there a few options available, I'm a little lost as to which one to go with. I'm currently leaning towards just using the regular 'net' module as it is already familiar to me. Since much of the client is already coded up, I'd really like to not switch over to using the HTML5 canvas just yet (but using socket.io would make a transition in the future more friendly, I think?). Any advice/direction on this matter would be much appreciated, though I do realize that there may be no one right answer. Edit: To be more specific, are there any client-side socket.io frameworks available that allow for communication between an Actionscript 3.0 client and a socket.io server and are robust enough to support current/future versions of socket.io? If not, what are the alternatives?

  • Bluetooth mouse Logitech M555b not recognized on a Macbook Pro 8.2

    - by Pierre
    I just bought a Logitech M555b Bluetooth mouse today. My computer (a Macbook Pro 8,2) has a bluetooth connection, and it works perfectly fine on Mac OSX (I set up a new device, click the connect button on the mouse, and voilà, done in 5 seconds). I cannot get it to work on Ubuntu 12.04. When I follow the same steps as on Mac OSX under Ubuntu 12.04, Sometimes I will see the mouse name appearing for 1 second on the screen, and if I'm fast enough to click on "Continue", I will have a message telling me the pairing with my mouse failed. Here are the steps I follow: Turn off Bluetooth on Ubuntu Turn Bluetooth on. Bluetooth icon Set up new device... Turn on the mouse, and press the Connect button. Press "Continue" on the Bluetooth New Device Setup screen I see the mouse name for one second, but then it disappear. Click on PIN options... to select '0000'. ... nothing, Ubuntu won't see anything. In the /var/log/syslog, I have the following information: May 27 23:26:16 Trane bluetoothd[896]: HCI dev 0 down May 27 23:26:16 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been disabled May 27 23:26:58 Trane bluetoothd[896]: HCI dev 0 up May 27 23:26:58 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been enabled May 27 23:26:58 Trane bluetoothd[896]: Inquiry Cancel Failed with status 0x12 May 27 23:28:26 Trane bluetoothd[896]: Refusing input device connect: No such file or directory (2) May 27 23:28:26 Trane bluetoothd[896]: Refusing connection from 00:1F:20:24:15:3D: setup in progress May 27 23:28:26 Trane bluetoothd[896]: Discovery session 0x7f3409ab5b70 with :1.84 activated I tried for an hour, I restarted my computer, re-paired the mouse on Mac OSX, etc. Sometimes when I restart the computer, I have a dialog box showing up saying that the mouse M555b wants to access some resources or something, if I click "Grant", or even if I tick "always grant access", nothing happens...

  • Bookmark Sentry Scans Your Chrome Bookmarks File For Bad Links and Dupes

    - by Jason Fitzpatrick
    Chrome: Bookmark Sentry, a free Chrome extension, takes the hard work out of checking your bookmark file for bad links and duplicates. Install it, forget about it, and get scheduled reports on the state of your bookmarks file. It’s that simple. Once you install the extension, open the options to toggle some basic settings to your liking (like the frequency of the scan, how long you want it to wait for a response, and whether you want it to look for bad links and/or duplicates). Once it finishes scanning you’ll get a report indicating the status of the links (why they are marked as missing or duped) and the ability to selectively or mass delete them. The only caveat we’d share is that it will tell you links behind any sort of security are unavailable. If you bookmark pages that you use for work, behind your corporate firewall for example, if the scanner runs when you’re not authenticated then it won’t be able to reach them. Other than that, it works like a charm. Bookmark Sentry is free, Google Chrome only.

  • Colour output piped to less

    Operating system: Mac OS 10.6.2 I'd like to be able to see colour output when piping certain commands through less. Two examples: I've got ls aliased to ls --color=auto, so I'd like to be able to see colour when I do this: ls -l | less I've also got the color extension turned on in Mercurial, so I'd like to see colour output from: hg diff | less and hg st | less After some googling, it seems like some versions of less support either -r or -R to make this work, but no dice for me. I can't see anything in the man page that looks like what I need. (-r or -R SEEM to be the right options, but again, they don't seem to work)

  • Web App Server hardware question. Which configuration?

    - by JBeckton
    I am pricing some new servers and I am not sure which configuration to get. The server will be running several web applications for our company. Some of them are ASP.Net sites and some are ColdFusion. The OS will be Win Server 2008 Web or Standard Edition. Do I need 2 processors or will a single quad core handle it? Xeon multi core Hyperthreading or non Hyperthreading? I am going 64bit so I can go higher than 4 Gigs of Ram. I am shopping at Dell and there are so many options, I want to get the most bang for my buck without going over budget and I also don't want the machine to be mostly under utilized.

  • Virtualmin deactivating PHP on new virtual servers

    - by Josh
    This is related to my other question... but the situation is much worse now. After updating to the most recent version of Virtualmin, when I create new accounts, Virtualmin sets up their VirtualHost entries as follows: <Directory /home/username/public_html> Options -Indexes +IncludesNOEXEC +FollowSymLinks +ExecCGI allow from all AllowOverride All AddHandler fcgid-script .php FCGIWrapper /home/username/fcgi-bin/php.fcgi .php </Directory> <Directory /home/username/cgi-bin> allow from all </Directory> [...] RemoveHandler .php Now, not only is it specifically inserting AddHandler fcgid-script and FCGIWrapper... which I do not want because I am using mod_fastcgi, but it's also setting up PHP in such a way that it will never work! It's adding a RemoveHandler .php after setting up the handler for PHP! Where is this behavior configured and how can I stop it? Better yet, how can I make Virtualmin not include any PHP commands at all in the VirtualHost section?

In the admin panel, if I click in MyStorage - Content - Upload, it just give me options to upload ISOs, VZDump backup files or OpenVZ templates. Would it be enough with a copy using scp? In that case, in which folder?

  • Cut in excel doesn't work, and copying tables from one program to another returns text

    - by Kristina
    My excel 2007 on Windows 7 operating system seems to have a probelm with regular cut function. when I highlight cells I want to cut and press cut (either on keyboard shortcut Ctrl+x, Home menu cut command, or from the right-click menu) cells start flashing for a split second and after that they only turn normal. When I want to paste them, they past as if copy function was used. If I try to rightclick to use function "insert cut cells" it is not one of the offered options at all. On my home computer I have same combination, Excel 2007 on windows 7 and it works just fine. COuld the problem be due to 64-bit win7 version at my job, and 32-bit version at home? Another problem is when I copy table from excel to word, in word pasting results in unformatted text instead of table as it was in excel. Did someone have such problems and can offer a solution? Thanx a lot.
