  • Maven Command Line for NetBeans RCP Developers

    - by Geertjan
    In the ongoing work being done on Maven documentation support for NetBeans Platform developers, the tutorial describing how to use the Maven command line to set up and develop applications on the NetBeans Platform has ben updated: http://platform.netbeans.org/tutorials/nbm-maven-commandline.html An interesting next step after following the tutorial above is to... open the result into the free community edition of IntelliJ IDEA: It's not hard to register the JDK and Maven in IntelliJ IDEA and to then run your application directly from there. The point is that there's no requirement to use NetBeans IDE if you want to create applications on top of its framework.

  • Using tslib (touchscreen input) with DirectFB on embedded system (gumstix overo)

    - by emi1faber
    I'm attempting to use tslib with DirectFB on the gumstix Overo. Everything seems to be compiled correctly, as when DirectFB starts up, I get messages saying "Started 'tslib Input' ... DirectFB/Input: tslib touchscreen 0 0.1 (tslib)" etc. However, I haven't been able to find any example code showing how one reads the X-Y coordinates of a touchscreen press. Is there any example code out there to initialize the touchscreen and return the coordinates of a touchscreen press? Thanks in advance, Ben

  • ubuntu gnome short cut keys

    - by benjipete
    Hi, I have done something quite silly and not sure how to fix it. I modified some of the gnome keyboard short cuts and was trying to disable the "Run Application" command. In the process I assigned it to the delete key and every time I hit delete the "Run Application" window comes up. It would not normally be a problem but the "Keyboard Shortcuts" no long has the short cut in the window so I can't disable it. Any help advice would be appreciated. Cheers Ben

  • ant (1.8.0/1.8.1) zip empty directories

    - by andersonbd1
    Hi, I noticed that neither the zip or jar targets are including empty directories. I googled a little and found this was a regression issue way back with 1.6 (.2 I think), but it was claimed to have been fixed. I was using 1.8.0 so I upgraded to 1.8.1, but am having the same issue. Anyone know of any workarounds besides adding dummy files to those directories? Thanks, Ben Anderson

  • mapping file-* to a property

    - by andersonbd1
    Hi, I'd like to: <unjar src="lib/mst-service-impl*.zip" but I can't put an asterisk in there. It is only one file, but I don't want to hardcode the version in there. Is there a way to create a property with the asterisk (I know this particular example doesn't work, but perhaps something along these lines): <property name="my.jar" file="lib/mst-service-impl*.zip"> so that I could then do this: <unjar src="${my.jar}" Thanks, Ben

  • Programatically importing a file and creating an instance of a class in Python

    - by benofsky
    I have a (python) list of strings which refer to python source files and subsequently classes within those files which I want to import and then create an instance of the classes within the files (everything follows a strict naming convention, making this theoretically possible), in Ruby I would do something like: require "lib/sources/#{source}.rb" s = source.constantize.new How would I do something similar in Python? Thanks, Ben

  • Regex for circular replacement

    - by polygenelubricants
    How would you use regex to write functions to do the following: Replace lowercase 'a' with uppercase and vice versa Where words are separated by whitespaces and > and < are special markers, replace >word with word< and vice versa Replace postincrement (i++;) with preincrement (++i;) and vice versa. Variable names are [a-z]+. Input is just a bunch of these statements. Bonus: also do decrement. Also interested in solutions in other flavors. Note: this is NOT a homework question. See also my previous explorations of regex: Regex split into overlapping strings (Alan Moore's answer is especially instructive) Can you use zero-width matching regex in String split? (my solution exploits a known Java regex bug with regards to non-obvious length lookbehind!)

  • Algorithms to find longest common prefix in a sliding window.

    - by nn
    Hi, I have written a Lempel Ziv compressor and decompressor. I am seeking to improve the time to search the dictionary for a phrase. I have considered K-M-P and Boyer-Moore, but I think an algorithm that adapts to changes in the dictionary would be faster. I've been reading that binary search trees (AVL or with splays) improve the performance of compression time considerably. What I fail to understand is how to bootstrap the binary search tree and insert/remove data. I'm not actually quite sure the significance of each node in the binary search. I am searching for phrases so will each character be considered a node? Also how and what is inserted/removed from the search tree as new data enters the dictionary and old data is removed? The binary search tree sounds like a good payoff since it can adapt to the dictionary, but I'm just not quite sure of how it's used.

  • String Occurance Counting Algorithm

    - by Hellnar
    Hello, I am curious what is the most efficient algorithm (or commonly used) to count the number of occurances of a string in a chunck of text. From what I read, Boyer–Moore string search algorithm is the standard for string search but I am not sure if counting occurance in an efficient way would be same as searching a string. In python this is what I want: text_chunck = "one two three four one five six one" occurance_count(text_chunck, "one") # gives 3. Regards EDIT: It seems like python str.count serves me such method however I am not able to find what algorithm it uses.

  • HttpContext.Items and Server.Transfer/Execute

    - by Rick Strahl
    A few days ago my buddy Ben Jones pointed out that he ran into a bug in the ScriptContainer control in the West Wind Web and Ajax Toolkit. The problem was basically that when a Server.Transfer call was applied the script container (and also various ClientScriptProxy script embedding routines) would potentially fail to load up the specified scripts. It turns out the problem is due to the fact that the various components in the toolkit use request specific singletons via a Current property. I use a static Current property tied to a Context.Items[] entry to handle this type of operation which looks something like this: /// <summary> /// Current instance of this class which should always be used to /// access this object. There are no public constructors to /// ensure the reference is used as a Singleton to further /// ensure that all scripts are written to the same clientscript /// manager. /// </summary> public static ClientScriptProxy Current { get { if (HttpContext.Current == null) return new ClientScriptProxy(); ClientScriptProxy proxy = null; if (HttpContext.Current.Items.Contains(STR_CONTEXTID)) proxy = HttpContext.Current.Items[STR_CONTEXTID] as ClientScriptProxy; else { proxy = new ClientScriptProxy(); HttpContext.Current.Items[STR_CONTEXTID] = proxy; } return proxy; } } The proxy is attached to a Context.Items[] item which makes the instance Request specific. This works perfectly fine in most situations EXCEPT when you’re dealing with Server.Transfer/Execute requests. Server.Transfer doesn’t cause Context.Items to be cleared so both the current transferred request and the original request’s Context.Items collection apply. For the ClientScriptProxy this causes a problem because script references are tracked on a per request basis in Context.Items to check for script duplication. Once a script is rendered an ID is written into the Context collection and so considered ‘rendered’: // No dupes - ref script include only once if (HttpContext.Current.Items.Contains( STR_SCRIPTITEM_IDENTITIFIER + fileId ) ) return; HttpContext.Current.Items.Add(STR_SCRIPTITEM_IDENTITIFIER + fileId, string.Empty); where the fileId is the script name or unique identifier. The problem is on the Transferred page the item will already exist in Context and so fail to render because it thinks the script has already rendered based on the Context item. Bummer. The workaround for this is simple once you know what’s going on, but in this case it was a bitch to track down because the context items are used in many places throughout this class. The trick is to determine when a request is transferred and then removing the specific keys. The first issue is to determine if a script is in a Trransfer or Execute call: if (HttpContext.Current.CurrentHandler != HttpContext.Current.Handler) Context.Handler is the original handler and CurrentHandler is the actual currently executing handler that is running when a Transfer/Execute is active. You can also use Context.PreviousHandler to get the last handler and chain through the whole list of handlers applied if Transfer calls are nested (dog help us all for the person debugging that). For the ClientScriptProxy the full logic to check for a transfer and remove the code looks like this: /// <summary> /// Clears all the request specific context items which are script references /// and the script placement index. /// </summary> public void ClearContextItemsOnTransfer() { if (HttpContext.Current != null) { // Check for Server.Transfer/Execute calls - we need to clear out Context.Items if (HttpContext.Current.CurrentHandler != HttpContext.Current.Handler) { List<string> Keys = HttpContext.Current.Items.Keys.Cast<string>().Where(s => s.StartsWith(STR_SCRIPTITEM_IDENTITIFIER) || s == STR_ScriptResourceIndex).ToList(); foreach (string key in Keys) { HttpContext.Current.Items.Remove(key); } } } } along with a small update to the Current property getter that sets a global flag to indicate whether the request was transferred: if (!proxy.IsTransferred && HttpContext.Current.Handler != HttpContext.Current.CurrentHandler) { proxy.ClearContextItemsOnTransfer(); proxy.IsTransferred = true; } return proxy; I know this is pretty ugly, but it works and it’s actually minimal fuss without affecting the behavior of the rest of the class. Ben had a different solution that involved explicitly clearing out the Context items and replacing the collection with a manually maintained list of items which also works, but required changes through the code to make this work. In hindsight, it would have been better to use a single object that encapsulates all the ‘persisted’ values and store that object in Context instead of all these individual small morsels. Hindsight is always 20/20 though :-}. If possible use Page.Items ClientScriptProxy is a generic component that can be used from anywhere in ASP.NET, so there are various methods that are not Page specific on this component which is why I used Context.Items, rather than the Page.Items collection.Page.Items would be a better choice since it will sidestep the above Server.Transfer nightmares as the Page is reloaded completely and so any new Page gets a new Items collection. No fuss there. So for the ScriptContainer control, which has to live on the page the behavior is a little different. It is attached to Page.Items (since it’s a control): /// <summary> /// Returns a current instance of this control if an instance /// is already loaded on the page. Otherwise a new instance is /// created, added to the Form and returned. /// /// It's important this function is not called too early in the /// page cycle - it should not be called before Page.OnInit(). /// /// This property is the preferred way to get a reference to a /// ScriptContainer control that is either already on a page /// or needs to be created. Controls in particular should always /// use this property. /// </summary> public static ScriptContainer Current { get { // We need a context for this to work! if (HttpContext.Current == null) return null; Page page = HttpContext.Current.CurrentHandler as Page; if (page == null) throw new InvalidOperationException(Resources.ERROR_ScriptContainer_OnlyWorks_With_PageBasedHandlers); ScriptContainer ctl = null; // Retrieve the current instance ctl = page.Items[STR_CONTEXTID] as ScriptContainer; if (ctl != null) return ctl; ctl = new ScriptContainer(); page.Form.Controls.Add(ctl); return ctl; } } The biggest issue with this approach is that you have to explicitly retrieve the page in the static Current property. Notice again the use of CurrentHandler (rather than Handler which was my original implementation) to ensure you get the latest page including the one that Server.Transfer fired. Server.Transfer and Server.Execute are Evil All that said – this fix is probably for the 2 people who are crazy enough to rely on Server.Transfer/Execute. :-} There are so many weird behavior problems with these commands that I avoid them at all costs. I don’t think I have a single application that uses either of these commands… Related Resources Full source of ClientScriptProxy.cs (repository) Part of the West Wind Web Toolkit Static Singletons for ASP.NET Controls Post © Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

  • Microsoft Templates included in jQuery 1.5!

    - by Stephen Walther
    When I joined the ASP.NET team as the Program Manager for Ajax, the ASP.NET team was working on releasing a new version of the Microsoft Ajax Library. This new version of the Microsoft Ajax Library had several really innovative and unique features such as support for client templates, client data-binding, script dependency management, and globalization. However, we kept hearing the message that our customers wanted to use jQuery when building ASP.NET applications. Therefore, about ten months ago, we decided to pursue a risky strategy. Scott Guthrie sent me to Cambridge to meet with John Resig – the creator of jQuery and leader of the jQuery project – to find out whether Microsoft and jQuery could work together. We wanted to find out whether the jQuery project would be open to allowing Microsoft to contribute the innovative features that we were developing for the Microsoft Ajax Library -- such as client templates and client data-binding -- to the jQuery library. Fortunately, the Cambridge meeting with Resig went well. John Resig was very open to accepting contributions to the jQuery library. Over the next few months, we worked out a process for Microsoft to contribute new features to the open-source jQuery project. Resig and Guthrie appeared on stage at the MIX10 conference to announce that Microsoft would be contributing features to jQuery. It has been a long journey, but I am happy to report success. Today, Microsoft and the jQuery project have announced that three plugins developed by developers on the ASP.NET team – the jQuery Templates, jQuery Data Link, and jQuery Globalization plugins – have been accepted as official jQuery plugins. In addition, the jQuery Templates plugin will be integrated into jQuery 1.5 which is the next major release of jQuery. You can learn more about the plugins by watching the following Web Camps TV episode hosted by James Senior with Stephen Walther: Web Camps TV #5 - Microsoft Commits Code to jQuery! You can read Scott Guthrie’s blog announcement here: http://weblogs.asp.net/scottgu/archive/2010/10/04/jquery-templates-data-link-and-globalization-accepted-as-official-jquery-plugins.aspx You can read the jQuery team’s announcement here: http://blog.jquery.com/2010/10/04/new-official-jquery-plugins-provide-templating-data-linking-and-globalization/ I wrote the original proposal for the jQuery Templates plugin. Dave Reed and Boris Moore were the ASP.NET developers responsible for actually writing the plugin (with lots of input from the jQuery team and the jQuery community). Boris has written a great set of tutorials on the Templates plugin. The first tutorial in his series is located here: http://www.borismoore.com/2010/09/introducing-jquery-templates-1-first.html I want to thank John Resig, Richard Worth, Scott Gonzalez, Rey Bango, Jorn Zaefferer, Karl Swedberg and all of the other members of the jQuery team for working with the ASP.NET team and accepting our contributions to the jQuery project.

  • The best Bar on the globe is ... in Seoul/Korea

    - by Mike Dietrich
    As you know already sometimes I write about things which really don't have to do anything with a database upgrade. So if you are looking for tips and tricks and articles about that topic please stop reading now Actually I'm not a lets-go-to-a-bar person. I enjoy good food and a fine dessert wine afterwards. But last week in Seoul/Korea Ryan, our local host, did ask us after a wonderful dinner at a Korean Barbecue place if we'd like to visit a bar. I was really tired as I flew into Seoul overnight from Sunday to Monday arriving Monday early morning, getting shower, breakfast - and then a full day of very good and productive customer meetings. But one thing Ryan mentioned catched my immediate attention: The owner of the bar collects records and has a huge tube amp stereo system - and you can ask him to play your favorite songs. The bar is called "Peter, Paul and Mary" - honestly not my favorite style of music. And I even coulnd't find a webpage or an address - only that little piece of information on Facebook. But after stepping down the stairs to the cellar my eyes almost poped out of my head. This is the audio system: Enourmus huge corner horn loudspeakers from Western Electric. Pretty old I'd suppose but delivering an incredible present dynamics into the room. And plenty of tube equipment from Jadis, NSA Labs and Shindo Laboratories Western Electric 300B Limited amps from Tokyo. And the owner (I was so amazed I had simply forgotten to ask for his name) collects records since 40 years. And we had many wishes that night. Actually when we did enter Peter, Paul and Mary he played an old Helloween song. That must have been destiny. A German entering a bar in Korea and the owner is playing an old song by one of Germany's best heavy metal bands ever. And it went on with the Doors, Rainbow's Stargazer, Scorpions, later Deep Purple's Perfect Strangers, a bit of Santana, Carly Simon, Jimi Hendrix, David Bowie ...Ronnie James Dio's Holy Diver, Gary Moore, Peter Gabriel's San Jacinto ... and many many more great songs ... Of course we were the last guests leaving the place at 2am in the morning - and I've never ever had a better night in a bar before ... I could have stayed days listening to so many records  ... Thanks Ryan, that was a phantastic night! -Mike
