  • How do I fool 12.10 to think it uses Unity2d in order to get the resolution my screen can use?

    - by Konstapel Kask
    On a laptop (model older) I have two screens (one built in, one external). I wish to use them both at the same time, but the settings app complains: Requested size (2944, 1080) exceeds 3D hardware limit (2048, 2048). You must either rearrange the displays so that they fit within a (2048, 2048) square or select the Ubuntu 2D session at login. The problem though, Unity 2D has been discontinued. I have forced Ubuntu to render Unity in 2D mode (with the help of echo export UNITY_LOW_GFX_MODE=1 >> .xprofile in accordance to this askubuntu post. But the error message still remains. How can one get the resolution that my computer supports? Or, how can I assure Ubuntu that it truly does use a 2D session?

  • What is "Unlock keyring" and how do I get rid of it?

    - by cipricus
    (In my case this message never appeared before installing Ubuntu One - see this question). Can I use Ubuntu One and avoid being prompted each time like this? I use Lubuntu 12.04. Edit: After exchanging comments I add the supplementary info: I am asked for password and to select session if I log out and in (auto-login is NOT set). Ubuntu One is installed but set NOT to start with session. Keyring appears nonetheless. Before installing Ubuntu One this didn't happen. Also, following the advice of con-f-use, I have entered ps -A | grep -i ubunt[u] in terminal, and got 2346 ? 00:00:01 ubuntuone-syncd, which means that ubuntuone is running when it was not supposed to.

  • How do you off load work from the database?

    - by TheLQ
    In at least the web development field, web servers are everywhere but are backed by very few database servers. As web servers get hit with requests they execute large queries on the database, putting the server under heavy load. While web servers are very easy to scale, db servers are much harder (at least from what I know), making them a precious resource. One way I've heard from some answers here to take load off the database is to offload the work to the web server. Easy, until you realize that now you've got a ton of traffic internally as a web server tries to run SELECT TOP 3000 (presumably to crunch the results on its own), which still slows things down. What are other ways to take load off the database?

  • Querying Literals in Entity SQL

    Entity SQL might surprise you if you are building query expressions with some non-string types.

  • Random MongoDb Syntax: Updates

    - by Liam McLennan
    I have a MongoDb collection called tweets. Each document has a property system_classification. If the value of system_classification is ‘+’ I want to change it to ‘positive’. For a regular relational database the query would be: update tweets set system_classification = 'positive' where system_classification = '+' the MongoDb equivalent is: db.tweets.update({system_classification: '+'}, {$set: {system_classification:'positive'}}, false, true) Parameter Description { system_classification: '+' } the first parameter identifies the documents to select { $set: { system_classification: 'positive' } } the second parameter is an operation ($set) and the parameter to that operation {system_classification: ‘positive’} false the third parameter indicates if this is a regular update or an upsert (true for upsert) true the final parameter indicates if the operation should be applied to all selected documents (or just the first)

  • Tomboy won't start

    - by torbengb
    I've just discovered Tomboy and like it. I added it to the startup applications, and on next boot Tomboy won't start. It then also won't start when I select it manually from the menu. I unchecked its entry in the startup applications and rebooted, but it still won't start. I uninstalled it and installed it again in order to perhaps fix some broken file or setting, but it didn't help. I saw this question and added the Applet. But the applet says "Tomboy Notes" has quit unexpectedly and a reload doesn't work; the message appears again. How can I determine (and fix!) what's wrong?

  • RPC protocols comparison

    - by Ricardo
    I have to select a protocol/technology to use for communicating a client-server architecture, with support both for Python and C. The main requirements are: Symmetrical communication in between ends: clients establish a connection and servers can send data back to clients through the same connection. Avoid excessive overhead by using HTTP or a big stack (if possible, TCP direct communication). TLS/SSL support for secure communications. Ease of implementation. For that, I evaluated the following protocols/communications technologies. Is the information on this table accurate and correct? (*1) TLS support for RPyC is based in a no-longer supported Python library.

  • My ASUS U32U with fresh Xubuntu install shows a black screen 50-80% of the startups

    - by Jona Ekenberg
    I have recently installed Ubuntu 12.10 with Xubuntu-package on my ASUS U32U notebook (Radeon HD 6320 GPU). The issue I have is that more often than not, after the GRUB-select screen I get a black screen, and three times total white lines (kind of) flashes very quickly (with maybe 5 seconds between each flash). I'm not even able to get to the login-screen (nor the Xubuntu loading screen). At first I thought it was simply me having installed something dumb or messed up some settings, but even after reformatting the partition and installing ubuntu again, the problem remains. Before I formatted it xfce4's window manager wouldn't start either, but it does now (when I am able to see anything). I can access the virual consoles (ctrl+alt+f1), but I can't see anything, but I've managed to shutdown the computer by using it (sudo shutdown -h now).

  • Remote connection problem.

    - by Woody
    Hello I have ubuntu 10.04 installed with mysql on it and I have a problem with remote connection. When I connect through putty it works but sometimes it looks like it hangs for example when I execute the command ln --help. Also with MySQL connection When I execute a simple query like show processlist; it works, but for example select * from table not always, if the table doesn't have many rows it works but if it has let's say more than 20 the query looks like it keeps working and never ends. It's connected but I can't do many things remotely. Added: I connect using putty from other windows pc, server is not overloaded. when i work at the same time directly on ubuntu i can do everything. Remotely not.

  • Recommended solutions for integrating iOS with .NET, at the service tier

    - by George
    I'm developing an application, in iOS, that is required to connect to my Windows Server to poll for new data, update, etc. As a seasoned C# developer, my first instinct is to start a new project in Visual Studio and select Web Service, letting my bias (and comfort level) dictate the service layer of my application. However, I don't want to be biased, and I don't base my decision on a service which I am very familiar with, at the cost of performance. I would like to know what other developers have had success using, and if there is a default standard for iOS service layer development? Are there protocols that are easier to consume than others within iOS? Better ones for the size and/or compression of data? Is there anything wrong with using SOAP? I know it's "big" in comparison to protocols like JSON.

  • SOLVED BleachBit: How to Completely Clear URL History in Firefox?

    - by tSquirrel
    14.04 / Firefox 29.0 I've been using Bleachbit to clear usage/file history, and for the most part it works great. However, it doesn't seem to clear the website hostnames out of the URL, at all. These addresses are not bookmarked. Also, the total URL isn't preserved, just the hostname. Visit site http://www.bluesnews.com/some_random_URL_string Exit Firefox Run Bleachbit, with ALL Firefox options selected Restart Firefox Check history: completely empty, other than bookmarked sites. www.bluesnews is NOT bookmarked Type "blue" which is Firefox automatically completes as "http://www.bluesnews.com/" Alternate Step #3: Use Firefox's built-in "Clear History" and select ALL entries with a time frame of "Everything". Same result as above. My inquiry in BB forums hasn't been responded to. I found Dan's proposed solution, however changing autocomplete in about:config only turns off the function, it doesn't actually stop storing URLs. SOLVED - See my comment in the "Answer" response from Tim

  • How would I go about setting a CSS gradient background in JavaScript?

    - by Dan
    The CSS gradient is described here, but I have no idea how to select for these properties in JavaScript. I would rather not use jQuery for this if at all possible. EDIT: Just doing the following doesn't seem to work... document.getElementById("selected-tab").style.background = "#860432"; document.getElementById("selected-tab").style.background = "-moz-linear-gradient(#b8042f, #860432)"; document.getElementById("selected-tab").style.background = "-o-linear-gradient(#b8042f, #860432)"; document.getElementById("selected-tab").style.background = "-webkit-gradient(linear, 0% 0%, 0% 100%, from(#b8042f), to(#860432))"; document.getElementById("selected-tab").style.background = "-webkit-linear-gradient(#b8042f, #860432)";

  • Sass interface in HTML6 for upload files.

    - by Anirudha
    Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/11/04/sass-interface-in-html6-for-upload-files.aspx[This post is about experiment & imagination] From Windows XP (ever last OS I tried) I have seen a feature that is about send file to pen drive and make shortcut on Desktop. In XP, Win7 (Win8 have this too, not removed) just select the file right click > send to and you can send this file to many places. In my menu it’s show me Skype because I have installed it. this skype confirm that we can add our own app here to make it more easy for user to send file in our app. Nowadays Many people use Cloud or online site to store the file. In case of html5 drag and drop you need to have site opened and have opened that page which is about file upload. You need to select all  and drag and drop. after drag and drop file is simply uploaded to server and site show you on list (if no error happen). but this file upload is seriously not worthy since I have to open the site when I do this operation.   Through this post I want to describe a feature that can make this thing better.  This API is simply called SASS FILE UPLOAD API Through This API when you surf the site and come into file upload page then the page will tell you that we also have SASS FILE API support. Enable it for better result.   How this work This API feature are activated on 2 basis. 1. Feature are disabled by default on site (or you can change it if it’s not) 2. This API allow specific site to upload the files. Files upload may have some rule. For example (minimum or maximum size of file to uploaded, which format the site allowed you to upload). In case of resume site you will be allowed to use .doc (according to code of site)   How browser recognize that Site have SASS service. In HTML source of  the site, the code have a meta tag similar to this <meta name=”sass-upload-api” path=”/upload.json”/> Remember that upload.json is one file that has define the value of many settings {   "cookie_name": "ck_file",   "maximum_allowed_perday": 24,   "allowed_file_extensions","*.png,*.jpg,*.jpeg,*.gif",   "method": [       {           "get": "file/get",           "routing":"/file/get/{fileName}"       },       {           "post": "file/post",           "routing":"/file/post/{fileName}"       },       {           "delete": "file/delete",           "routing":"/file/delete/{fileName}"       },         {           "put": "file/put",           "routing":"/file/put/{fileName}"       },        {           "all": "file/all",           "routing":"/file/all/{fileName}"       }    ] } cookie name is simply a cookie which should be stored in browser and define in json. we define the cookie_name so we can easily share then with service in Windows system. This cookie will be accessible with the service so it’s security based safe. other cookie will not be shared.   The cookie will be post,put, get from this location. The all location will be simply about showing a whole list of file. This will gave a treeview kind of json to show the directories on sever.   for example example.com if you have activated the API with this site then you will seen a send to option in your explorer.exe when you send you will got a windows open which folder you want to use to send the file. The windows will also describe the limit and how much you can upload. This thing never required site to opened. When you upload the file this will be uploaded through FTP protocol. FTP protocol are better for performance.   How this API make thing faster. Suppose you want to ask a question and want to post image. you just do it and get it ready when you open stackoverflow.com now stackoverflow will only tell you which file you want to put on your current question that you asking for. second use is about people use cloud app.   There is no need of drag and drop anymore. we just need to do it without drag and drop it. we doesn’t need to open the site either. This thing is still in experiment level. I will update this post when I got some progress on this API.

  • using GNU GPL v2 software as pointers to solution to problem

    - by Patrick
    I am coding a PHP serial access class and have been taking pointers from the PHP-serial class on Google Code (here). That class is based on PHP 4 and I'm creating a PHP 5 class that allows more functionality and is specific to some business demands I have. There is no code copied and I have done all the coding. Does the class I'm writing fall under the Google Code's GPL or am I free to select a license that I feel is appropriate? I'm not sure of the standard that applies to licensing when you are only looking to another work for pointers.

    I had a dual boot setup on my system, with ubuntu 11.04 and Win7. Yesterday I updated ubuntu to 11.10. Now , I cannot seem to be able to load Win7 , I do see an entry for it on the boot menu. I select that entry and then the screen goes black , with everything coming to a standstill. I tried to wait for it to respond but nothing happened. I went through the forums and tried "grub-update" but when I do that , nothing really happens. I am not sure of this , but I get no output from grub for upto 10 minutes ( can grub-update be made verbose ) How can I fix this and get back to booting both OS'es properly ?

  • Drag and drop fearture for a website

    I have to design a website which will have drag and drop features for creating an e-card. So you select items from a tool box and drag and drop this item on the card area. Once you have completed the design you can publish the e-card on the web by clicking "Save and publish" button. What are the possible technologies for implementing this feature? The requirement is that the application should not degrade the performance of the website, and should not take much time in publishing once the user click "Save and publish" button.

  • Changing default application

    - by ragebunny
    Hey i have recently installed Sublime text 2 and i must say it's one of the best text editors i've ever used or even seen in use. So i managed to install everything and added to the unity menu and also change all the entries of gedit.desktop to sublime.desktop and it works just fine for most files but i realised that some files still open in gedit, for example php files, i checked the default list for php but there isn't anything in there. So how would i set the default for opening php files? Update:Also Sublime doesn't show up in them properties menu where i can usually select the default program. Thanks for the help. I'm using 12.10.

  • SQL Strings vs. Conditional SQL Statements

    - by Yatrix
    Is there an advantage to piecemealing sql strings together vs conditional sql statements in SQL Server itself? I have only about 10 months of SQL experience, so I could be speaking out of pure ignorance here. Where I work, I see people building entire queries in strings and concatenating strings together depending on conditions. For example: Set @sql = 'Select column1, column2 from Table 1 ' If SomeCondtion @sql = @sql + 'where column3 = ' + @param1 else @sql = @sql + 'where column4 = ' + @param2 That's a real simple example, but what I'm seeing here is multiple joins and huge queries built from strings and then executed. Some of them even write out what's basically a function to execute, including Declare statements, variables, etc. Is there an advantage to doing it this way when you could do it with just conditions in the sql itself? To me, it seems a lot harder to debug, change and even write vs adding cases, if-elses or additional where parameters to branch the query.

  • How to clear a Firefox address bar without selecting its content?

    - by zuba
    Sometimes I need to move an url from an app to a browser. I select the url, say in gvim, and make Firefox window active. Then I see that I should clear address bar before pasting the new url, which requires selecting existing url, which wipes the new url from PRIMARY clipboard out. What is the best way to put the new url from PRIMARY clipboard to address bar? Is there a shortcut to clear address bar and then to move focus there? ps I know I can use Ctrl-C to put the new url to CLIPBOARD clipboard, but I prefer to use PRIMARY clipboard.
