  • Removing pulseaudio, about ALSAMixer

    - by allenskd
    I removed pulseaudio today because rosetta stone had conflicts identifying the microphone which kinda makes it useless to me to learn a new language. Thing is, Alsamixer seems to have screwed up so I'm not really familiar on which configuration file I have to tweak to make the whole system use alsamixer (actually it does... but the problem is this error) $ alsamixer ALSA lib pulse.c:229:(pulse_connect) PulseAudio: Unable to connect: Connection refused cannot open mixer: Connection refused Could anyone enlighten me on which configuration file I have to change?

  • SQL Server Unit Testing with tSQLt

    When one considers the amount of time and effort that Unit Testing consumes for the Database Developer, is surprising how few good SQL Server Test frameworks are around. tSQLt , which is open source and free to use, is one of the frameworks that provide a simple way to populate a table with test data as part of the unit test, and check the results with what should be expected. Sebastian and Dennis, who created tSQLt, explain.

  • Special 301: FOSS users. Now we're all Communists and Criminals

    <b>Free Software Magazine:</b> "There seems to be no respite from the predations of Microsoft FUD and the machinations of Big Business. Just when it seemed safe to come out of the closet and admit to being a user of free and open source software without being accused of being a Communist, it appears that we are now criminals too"

  • Attending my first software conference - any tips before I go? [closed]

    - by Paul Weber
    My nice employer allowed me to visit a software conference in June (International PHP Conference, for those who care). Wanting to make the most of it, I would ask the more experienced conference goers in here to give me some tips on what I could do to maximize my learning experience on the conference, and to reduce beginner mistakes. Sorry that this question is a little ambiguous, but I think it's best to keep it a little bit more open, so I can get a wide range of Ideas, and it will be of more use to further people seeking for an answer.

  • Understanding the Value of a DMOZ Submission

    The Open Directory Project (DMOZ) data powers the core directory services for many of the Internet's most influencial search engines and portals. However, Matt Cutts once said: "if you can't get into Dmoz, I wouldn't necessarily worry about it. There are a lot of other great places to get links across the web."

  • Strategy for avoiding duplicate object ids for data shared across devices using iCloud

    - by rmaddy
    I have a data intensive iOS app that is not using CoreData nor does it support iCloud synching (yet). All of my objects are created with unique keys. I use a simple long long initialized with the current time. Then as I need a new key I increment the value by 1. This has all worked well for a few years with the app running isolated on a single device. Now I want to add support for automatic data sync across devices using iCloud. As my app is written, there is the possibility that two objects created on two different devices could end up with the same key. I need to avoid this possibility. I'm looking for ideas for solving this issue. I have a few requirements that the solution must meet: 1) The key needs to remain a single integral data type. Converting all existing keys to a compound key or to a string or other type would affect the entire code base and likely result in more bugs than it's worth. 2) The solution can't depend on an Internet connection. A user must be able to run the app and add data even with no Internet connection. The data should still resolve properly later when the data syncs through iCloud once a connection is available. I'll accept one exception to this rule. If no other option is available, I may be open to requiring an Internet connection the first time the app's data is initialized. One idea I have been toying around with in my head is logically splitting the integer key into two parts. The high 4 or 5 bits could be used as some sort of device id while the rest represents the actual key. The fuzzy part is figuring out how to come up with non-conflicting device ids that fit in a few bits. This should be viable since I don't need to deal will millions of devices. I just need to deal with the few devices that would be shared by a given iCloud account. I'm open to suggestions. Thanks.

  • Nautilus statusbar visibilty - Quickly check free space

    - by Jeremy
    In prior versions, I would open Nautilus and check the statusbar, which would tell me how much free space there is. Now, the statusbar isn't shown by default. I know you can enable it from the View menu, but 99% of users won't do that (and I'd rather not do that, if possible). So, is there some new recommended way to keep tabs on hard drive usage? Or is there maybe some other method that I should have been using in the past but never noticed?

  • JCP.next.3: time to get to work

    - by Patrick Curran
    As I've previously reported in this blog, we planned three JSRs to improve the JCP’s processes and to meet our members’ expectations for change. The first - JCP.next.1, or more formally JSR 348: Towards a new version of the Java Community Process - was completed in October 2011. This focused on a small number of simple but important changes to make our process more transparent and to enable broader participation. We're already seeing the benefits of these changes as new and existing JSRs adopt the new requirements. However, because we wanted to complete this JSR quickly we deliberately postponed a number of more complex items, including everything that would require modifying the JSPA (the legal agreement that members sign when they join the organization) to a follow-on JSR. The second JSR (JSR 355: JCP Executive Committee Merge) is in progress now and will complete later this year. This JSR is even simpler than the first, and is focused solely on merging the two Executive Committees into one for greater efficiency and to encourage synergies between the Java ME and Java SE platforms. Continuing the momentum to move Java and the JCP forward we have just filed the third JSR (JCP.next.3) as JSR 358: A major revision of the Java Community Process. This JSR will modify the JSPA as well as the Process Document, and will tackle a large number of complex issues, many of them postponed from JSR 348. For these reasons we expect to spend a considerable amount of time working on it - at least a year, and probably more. The current version of the JSPA was created back in 2002, although some minor changes were introduced in 2005. Since then the organization and the environment in which we operate have changed significantly, and it is now time to revise our processes to ensure that they meet our current needs. We have a long list of topics to be considered, including the role of independent implementations (those not derived from the Reference Implementation), licensing and open source, ensuring that our new transparency requirements are implemented correctly, compatibility policy and TCKs, the role of individual members, patent policy, and IP flow. The Expert Group for JSR 358, as with all process-change JSRs, consists of all members of the Executive Committees. Even though the JSR has just been filed we started discussions on the various topics several months ago (see the EC's meeting minutes for details) and our EC members - including the new members who joined within the last year or two - are actively engaged. Now it's your opportunity to get involved. As required by version 2.8 of our Process (introduced with JSR 348) we will conduct all our business in the open. We have a public java.net project where you can follow and participate in our work. All of our deliberations will be copied to a public Observer mailing list, we'll track our issues on a public Issue Tracker, and all our documents (meeting agendas and minutes, task lists, working drafts) will be published in our Document Archive. We're just getting started, but we do want your input. Please visit us on java.net where you can learn how to participate. Let's get to work...

  • restore window sizes, drag and drop functionalty in Unity (a simple use case)

    - by Avetik Topchyan
    Once application is maximized (say "Cheese") how can I restore its size back to the original? Is it possible to drag-and-drop from one application to another application in Unity? If so, how can I do that? Suppose I have a Rhythmbox open and I would like to drag a picture from a Desktop location (actually where is it?) to Rhythmbox album art section in the lower left corner? Unity was poorly designed, IMHO.

  • Way(s) of browsing the filesystem that are more flexible

    - by ixtmixilix
    I have two related questions, both probably (but not necessarily preferentially) accepting the same answer : When browsing or exploring the filesystem in a GUI, I want to be able to right click on the empty space between the files, choose a menu item and say 'open terminal in this folder,' optionally as root Do the converse when using the terminal, optionally as root I use Universe with kubuntu but have Debian Lenny running with gnome installed separately, so anything on kde or gnome would work
