  • How can I get my printer working after upgrading to (K)ubuntu 13.10?

    - by Sparhawk
    When using (K)ubuntu 13.04, my network printer worked fine. After upgrading to (K)ubuntu 13.10 today, I can no longer print. I get the error "The printer is not responding." I've tried to add the printer again, and it is automatically recognised. I can add it, and select it from print dialogue boxes, but I get the same error. Brother HL-2040, Kubuntu 13.10 (KDE 4.11.2) ==EDIT== I attempted connecting the printer directly with a USB cable, and this worked fine, so it's not a problem with drivers. (FWIW I'm using the recommended HL-2040 Foomatic/hl1250.) Further, it prints fine over the network from my wife's MacBook.

  • sprite group doesn't support indexing

    - by user3956
    I have a sprite group created with pygame.sprite.Group() (and add sprites to it with the add method) How would I retrieve the nth sprite in this group? Code like this does not work: mygroup = pygame.sprite.Group(mysprite01) print mygroup[n].rect It returns the error: group object does not support indexing. For the moment I'm using the following function: def getSpriteByPosition(position,group): for index,spr in enumerate(group): if (index == position): return spr return False Although working, it just doesn't seem right... Is there a cleaner way to do this? EDIT: I mention a "position" and index but it's not important actually, returning any single sprite from the group is enough

  • BizTalk Orchestration & Port Tutorial Part 2

    - by bosuch
    In Part 1 I showed how to create and publish a simple Orchestration demo. Now we’ll finish configuring it in the admin console and test it. Open the BizTalk Server 2009 Administration Console, and expand BizTalk Server 2009 Administration, then Applications. You should have an entry for OrchestrationPortDemo – expand it as well. First, we’ll add the Receive Port – the place that we’ll drop the test file. Right-click on Receive Ports and select New One-way Receive Port. On the General tab, name it InputPort, then click over to Receive Locations.   Click New to add a new location. Your receive location can be FTP, SQL, WCF, SharePoint, or many other choices, but for this demo we’ll add a File location. Click the Configure button and set a receive folder (something like “C:\PortDemo\”) and a file mask (stick with “*.xml” for now) and click OK three times to create your Receive Port.   Next we’ll create the Send port – the location where BizTalk will drop the file. Right-click on Send Ports and choose New Static One-way Send Port. Give it an appropriate name, and configure the FILE Transport Properties as shown:   Click OK twice and your Send Port will be created. Now we’ll configure the Orchestration Bindings. Click on Orchestrations, then right-click the orchestration itself and select Properties. Select the Bindings tab. Choose BizTalkServerApplication as the host, and select the Send and Receive ports you previously created, as shown:   Now it’s time to fire everything up. Right-click on the send port you created and click Start. Once the Status column displays “Started”, click on Receive Locations and Enable the Receive Location previously created. Finally, start the Orchestration. Now, time to test! Create a simple xml file like: <root>    <Node1>Test</Node1>    <Node2>Test</Node2> </root> And drop it into the C:\PortDemo folder. After a couple of seconds the file should disappear – this indicates BizTalk has picked it up for processing. Look in the C:\PortDemo\Output folder and you should see an xml file with a GUID for a name, like {7C50104F-FC3E-4A49-B2FA-4F560A37636D}.xml. Open it to verify that it matches your input file. Practically, this demo doesn’t do a whole heck of a lot, but it shows you the basics for building, publishing and running an orchestration.

  • Ubuntu 14.04 get Windows 8 to show up

    - by user270129
    http://paste.ubuntu.com/7271888/ So I installed Ubuntu 14.04 on what used to be Ubuntu 12.04. I am dual booting with Windows 8.1. I haven't been able to access Ubuntu 12.04 since Windows 8.1 did some updates a few weeks back. Grub shows up and I can't see windows 8.1. How can I add Windows 8 using Boot Repair? I figured out how to install boot-repair in Ubuntu 14.04 by doing this workaround: https://bugs.launchpad.net/boot-repair/+bug/1267702 Most important thing: How can I add Windows 8.1 to the Grub menu using Boot Repair? I am not an expert by any means. Thank you.

  • What is the effect of creating unit tests during development on time to develop as well as time spent in maintenance activities?

    - by jgauffin
    I'm a consultant and I am going to introduce unit tests to all developers at my client site. My goal is to ensure that all new applications should have unit tests for all classes created. The client has a problem with high maintenance costs from fixing bugs in their existing applications. Their applications have a life span from between 5-15 years in which they continuously add new features. I'm quite confident that they will benefit greatly from starting with unit tests. I'm interested in the effect of unit tests on the time and cost of development: How much time will writing unit tests as part of the development process add? How much time will be saved in maintenance activities (testing and debugging) by having good unit tests?

  • 2d array permutation proof [migrated]

    I want to know if it's possible to get any possible combination of a 4x4 integer array given three rules: you may shift any column up or down you may shift any row left or right you may shift the entire array left, right, up, or down That is, you can transform: [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] into any possible combination of a 4x4 array of the same 16 values, given those three rules. Basically, I just want to know if there are impossible combinations.

  • How do I allow a non-default user to use serial device ttyUSB0?

    - by lucaghera
    I have an Ubuntu 11.10 system with 2 users: The first was created during the installation The second instead was created after. It belongs to the sudoers group. Now the problem is that when the second tries to use a device ttyUSB0 the following error is returned: "Could not open serial port /dev/ttyUSB0" I was able to fix it by using: sudo chown :second_user /dev/ttyUSB0 However when I disconnect the device and reconnect it the problem comes back. Is there a way to allow different users to access the devices? I suppose I have to add the user to a specific group. Currently the owner is root and the group is dialout. However I'm not sure about the group and I don't know how to add the user. Thanks!

  • Saving to a file in C# [on hold]

    - by user36322
    If I use this code: using (StreamWriter streamWriter = new StreamWriter("Content/player.txt", true)) { streamWriter.Write("Hello!"); streamWriter.Close(); } The program will not actually add "Hello!" to the file. However, if I use this code: using (StreamWriter streamWriter = new StreamWriter("C:/Users/Michael/Documents/Visual Studio 2010/Projects/PuzzleGame/PuzzleGame/PuzzleGameContent/player.TXT", true)) { streamWriter.Write("Hello!"); streamWriter.Close(); } The program will work as intended and add "Hello!" to the save file. Is there any way I can do this without hardcoding the path?

  • Do I need to do an "apt-get update" after adding a PPA?

    - by Sat93
    After adding a new ppa to the repository, is it necessary to update the whole database? By "whole database" I mean is it necessary to update index's of each and every packege? If it's not necessary, then how can I update only that specific package whose ppa I have just added into the repository. For example, if I add an ppa by typing the following in terminal, sudo add-apt-repository ppa:tiheum/equinox then we normally run the following command after it, sudo apt-get update But how can I update the only package which is associated with the above ppa, instead of updating the whole database.

  • Advise how to write a simple test for this javascript snippet?

    - by resting
    I'm trying to start unit testing (not using any testing frameworks) for my javascripts. Here's one example of it. var obj = {}; obj.disableBtn = function ($btn, style) { $btn.attr('disabled','disabled').addClass('disabled').removeClass(style); }; The use case is as such: obj.disableBtn($('.submit'), 'btn-blue'); What it does is simply add the disabled attribute, add the disabled class, and remove the btn-blue style. Please advise how would a typical test case look like in this case. I have a little knowledge on testing using assert(), but have no idea how to go about it when it involves verifying the result on HTML elements.

  • Best way to rename existing unique field names in database?

    - by Rajdeep Siddhapura
    I have a database table that contains id, filename, userId id is unique identifier filename should also be unique table may contain 10000 records When a user uploads a file it should be entered in database with given rules: If there is no record with same filename, it should be added as it is (Ex. foobar.pdf) If there is record with same filename, it should be added as uploadedName(2).ext (foobar(2).pdf) If there are n records with same base filename (foobar), it should be added as uploadedName(n+1).ext (foobar(20).pdf) Now if foobar(2).pdf is uploaded, it should be added as foobar(2)(2).pdf & so on This pattern needs to be followed because the file is already being uploaded at client side using ajax before sending the details to server and the file hosting service follows the above rules to name the files. My solution: maintain a file that contains all the names and the number of times it has occurred. if a filename that exists in file is entered, increase occurrence count and new name is generated, else add to it to file if the new name generated is in database, add it to file and generate new name
