  • How do I change the date format in Gnome 3 shell?

    - by James Haigh
    I want to change the date/time format on the top panel to a format close to RFC 3339 / ISO 8601, like one of these: %F %T ? 2013-06-24 16:13:00 %F %a %T ? 2013-06-24 Mon 16:13:00 %A %F %T ? Monday 2013-06-24 16:13:00 I know Unity has a preference somewhere hidden away in dconf, this is how I did it in Unity, but I can't find such a preference for Gnome 3 shell. Preferably, I'd also like to set one of these as my system-wide date/time locale preference.

  • S11 launched

    - by unixman
    Now that Oracle Solaris 11 is out, its time to do 2 things -- 1) Its time to see what's in it, what's new and why its important, and then assess why it might make sense to begin evaluating it for your needs and 2) Its time to acknowledge, give thanks to and congratulate all the R&D personnel, architects, engineers, designers and testers who've put in so much effort and energy into helping make Solaris 11 (and SunOS 5.11) what it has become -- starting way back circa 2004 and, more importantly, culminating in the recent years and months -- staying focused on the execution, unwavering in the face of various challenges. For #1 above, here are a few good things to get going with - Watch the product launch replay - Visit the Solaris 11 Spotlight section on oracle.com - Get comfortable through introductory videos and detailed "how-to" guides (ex: how to create and publish IPS packages), white papers on the new default root file system, ZFS, and reap the benefits brought on by the fundamental shift in easing the administration experience - Look at the next level of software lifecycle management that is enabled by technologies such as Automated Installer and Image Packaging System -- that dramatically address patch management-related challenges - Understand how we continue to innovate in areas of service intelligence, reliability and availability - Start to evaluate enhancements in virtualization capabilities -- whether influenced by the need to consolidate or motivated by the need to have increased service mobility across physical systems, leveraging hardware-level abstractions - Gain more control over your network-centric services through enhancements in network resource management, observability and I/O performance - Look beyond your existing infrastructure with confidence that you can re-host and transition to newer systems with the use of Solaris 10 zones running on top of Solaris 11 - Relish in the fact that you can do all this, get your data to be secure and encrypted and more, on both, SPARC and x86-based systems. - Stay informed by keeping an eye on relevant blogs, which we've begun turning up recently. - Go through a hands-on lab - Sign up to take a class or just opt to watch various videos to begin to raise your comfort level with these technologies For #2 above -- There are many ways to do that. One way is to just say "thanks" with an email, a post, or a simple card,  similar to this one seen at a Barnes and Noble store recently.  The front of the card is followed by what's inside... and as the saying goes, now more then ever "it's what's inside that counts" And here's the inside of the card: So, what are you waiting for ? Go download and try it out, and please let us know what you think of it!

  • Ubuntu 12.10 - Dual monitors

    - by crazy coder
    I'm trying to set up a dual monitor with my laptop (Dell XPS L502X) and a monitor that I recently bought (Dell U2312HM). The cable are alright, because I tried this on Windows and all is fine. In Ubuntu 12.10 doesn't work. If I go to System Settings-Displays, button Detect Displays doesn't do anything. I may also say that I use Bumblebee, and my sudo nvidia-settings command only shows a windows with only nvidia-setting Configuration option.

    On my command line only Ubuntu machine, the login prompt occasionally shows a warning: Ubuntu 12.04 LTS myserver tty1 myserver login: [833747.589882] ipheth: ipheth_rcvbulk_callback: urb status: -71 Nothing is obviously wrong with the system, and I can enter my username and password without issue. What does this message mean and should I be worried about it? Edit: I've found plugging in and then removing my iPhone from the computer causes this message. I'm still looking for what it means.

  • Java word scramble game [closed]

    - by Dan
    I'm working on code for a word scramble game in Java. I know the code itself is full of bugs right now, but my main focus is getting a vector of strings broken into two separate vectors containing hints and words. The text file that the strings are taken from has a colon separating them. So here is what I have so far. public WordApp() { inputRow = new TextInputBox(); inputRow.setLocation(200,100); phrases = new Vector <String>(FileUtilities.getStrings()); v_hints = new Vector<String>(); v_words = new Vector<String>(); textBox = new TextBox(200,100); textBox.setLocation(200,200); textBox.setText(scrambled + "\n\n Time Left: \t" + seconds/10 + "\n Score: \t" + score); hintBox = new TextBox(200,200); hintBox.setLocation(300,400); hintBox.hide(); Iterator <String> categorize = phrases.iterator(); while(categorize.hasNext()) { int index = phrases.indexOf(":"); String element = categorize.next(); v_words.add(element.substring(0,index)); v_hints.add(element.substring(index +1)); phrases.remove(index); System.out.print(index); } The FileUtilities file was given to us by the pofessor, here it is. import java.util.*; import java.io.*; public class FileUtilities { private static final String FILE_NAME = "javawords.txt"; //------------------ getStrings ------------------------- // // returns a Vector of Strings // Each string is of the form: word:hint // where word contains no spaces. // The words and hints are read from FILE_NAME // // public static Vector<String> getStrings ( ) { Vector<String> words = new Vector<String>(); File file = new File( FILE_NAME ); Scanner scanFile; try { scanFile = new Scanner( file); } catch ( IOException e) { System.err.println( "LineInput Error: " + e.getMessage() ); return null; } while ( scanFile.hasNextLine() ) { // read the word and follow it by a colon String s = scanFile.nextLine().trim().toUpperCase() + ":"; if( s.length()>1 && scanFile.hasNextLine() ) { // append the hint and add to collection s+= scanFile.nextLine().trim(); words.add(s); } } // shuffle Collections.shuffle(words); return words; } }

  • Unsafe shutdown on power button press (Ubuntu Server 13.10)

    - by Sam Bloomberg
    I have Ubuntu Server 13.10 set up on a machine, and whenever I press (not press and hold) the power button the machine doesn't safely shutdown (it instantly powers off), though it does flash the message "acpid: exiting" before turning off. If I instead run shutdown -h now, it goes through the usual cycle of stopping processes, unmounting filesystems, etc... Any ideas why this might be? I want the power button to safely shut down the system (unless I hold it down, of course).

  • video-programs seem to be "wreckoned"?

    - by dschinn1001
    Is it because I have to many different video-players installed ? after update from 12.04 to 12.10 it seems, that video-playing is not working any more ? it crashes, or ends up with "we have found a system-failure" - window. (failure-report is not working and crashing too after correct password). this concerns: medibuntu, mediaplayer, totem, mplayer and xine (probably too many installed and I should decide for only one ? - but it was no problem in 12.04 ?).

  • Path of Replication

    - by geeko
    I'm currently developing a replication system to keep data in-synch between an arbitrary number of servers. Some of these servers exist in one cluster on one LAN. Others exist somewhere else in the world. I'm wondering what are the pros/cons of different paths that we choose to flow replicated data on between servers? In other words, what are the different strategies to load balance the replication process ?

  • Adding JavaScript to your code dependent upon conditions

    - by DavidMadden
    You might be in an environment where you code is source controlled and where you might have build options to different environments.  I recently encountered this where the same code, built on different configurations, would have the website at a different URL.  If you are working with ASP.NET as I am you will have to do something a bit crazy but worth while.  If someone has a more efficient solution please share. Here is what I came up with to make sure the client side script was placed into the HEAD element for the Google Analytics script.  GA wants to be the last in the HEAD element so if you are doing others in the Page_Load then you should do theirs last. The settings object below is an instance of a class that holds information I collection.  You could read from different sources depending on where you stored your unique ID for Google Analytics. *** This has been formatted to fit this screen. *** if (!IsPostBack) { if (settings.GoogleAnalyticsID != null || settings.GoogleAnalyticsID != string.Empty) { string str = @"//<!CDATA[ var _gaq = _gaq || []; _gaq.push(['_setAccount', '"  + settings.GoogleAnalyticsID + "']); _gaq.push(['_trackPageview']);  (function () {  var ga = document.createElement('script');  ga.type = 'text/javascript';  ga.async = true;  ga.src = ('https:' == document.location.protocol  ? 'https://ssl' :  'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0];  s.parentNode.insertBefore(ga, s);})();"; System.Web.UI.HtmlControls.HtmlGenericControl si =  new System.Web.UI.HtmlControls.HtmlGenericControl(); si.TagName = "script"; si.Attributes.Add("type", @"text/javascript"); si.InnerHtml = sb.ToString(); this.Page.Header.Controls.Add(si); } } The code above will prevent the code from executing if it is a PostBack and then if the ID was not able to be read or something caused the settings to be lost by accident. If you have larger function to declare, you can use a StringBuilder to separate the lines. This is the most compact I wished to go and manage readability.

  • What does path finding in internet routing do and how is it different from A*?

    - by alan2here
    Note: If you don't understand this question then feel free to ask clarification in the comments instead of voting down, it might be that this question needs some more work at the moment. I've been directed here from the Stack Excange chat room Root Access because my question didn't fit on Super User. In many aspects path finding algorithms like A star are very similar to internet routing. For example: A node in an A* path finding system can search for a path though edges between other nodes. A router that's part of the internet can search for a route though cables between other routers. In the case of A*, open and closed lists are kept by the system as a whole, sepratly from any individual node as well as each node being able to temporarily store a state involving several numbers. Routers on the internet seem to have remarkable properties, as I understand it: They are very performant. New nodes can be added at any time that use a free address from a finite (not tree like) address space. It's real routing, like A*, there's never any doubling back for example. Similar IP addresses don't have to be geographically nearby. The network reacts quickly to changes to the networks shape, for example if a line is down. Routers share information and it takes time for new IP's to be registered everywhere, but presumably every router doesn't have to store a list of all the addresses each of it's directions leads most directly to. I'm looking for a basic, general, high level description of the algorithms workings from the point of view of an individual router. Does anyone have one? I presume public internet routers don't use A* as the overheads would be to large, and scale to poorly. I also presume there is a single method worldwide because it seems as if must involve a lot of transferring data to update and communicate a reasonable amount of state between neighboring routers. For example, perhaps the amount of data that needs to be stored in each router scales logarithmically with the number of routers that exist worldwide, the detail and reliability of the routing is reduced over increasing distances, there is increasing backtracking involved in parts of the network that are less geographically uniform or maybe each router really does perform an A* style search, temporarily maintaining open and closed lists when a packet arrives.

  • Are separate business objects needed when persistent data can be stored in a usable format?

    - by Kylotan
    I have a system where data is stored in a persistent store and read by a server application. Some of this data is only ever seen by the server, but some of it is passed through unaltered to clients. So, there is a big temptation to persist data - whether whole rows/documents or individual fields/sub-documents - in the exact form that the client can use (eg. JSON), as this removes various layers of boilerplate, whether in the form of procedural SQL, an ORM, or any proxy structure which exists just to hold the values before having to re-encode them into a client-suitable form. This form can usually be used on the server too, though business logic may have to live outside of the object, On the other hand, this approach ends up leaking implementation details everywhere. 9 times out of 10 I'm happy just to read a JSON structure out of the DB and send it to the client, but 1 in every 10 times I have to know the details of that implicit structure (and be able to refactor access to it if the stored data ever changes). And this makes me think that maybe I should be pulling this data into separate business objects, so that business logic doesn't have to change when the data schema does. (Though you could argue this just moves the problem rather than solves it.) There is a complicating factor in that our data schema is constantly changing rapidly, to the point where we dropped our previous ORM/RDBMS system in favour of MongoDB and an implicit schema which was much easier to work with. So far I've not decided whether the rapid schema changes make me wish for separate business objects (so that server-side calculations need less refactoring, since all changes are restricted to the persistence layer) or for no separate business objects (because every change to the schema requires the business objects to change to stay in sync, even if the new sub-object or field is never used on the server except to pass verbatim to a client). So my question is whether it is sensible to store objects in the form they are usually going to be used, or if it's better to copy them into intermediate business objects to insulate both sides from each other (even when that isn't strictly necessary)? And I'd like to hear from anybody else who has had experience of a similar situation, perhaps choosing to persist XML or JSON instead of having an explicit schema which has to be assembled into a client format each time.

  • How can I add a new user as sudoer using the command line?

    - by David B
    After I add a user using adduser, I can't see it via System->Administration->Users and Groups unless I logout then login again. Is that normal? Also, can I set a newly added user as a sudoer or do I have to change that only after adding it? How can I do that via the shell? Finally, can I delete the original user that was created upon initial installation of ubuntu, or is this user somehow 'special'?
