  • Named my RPi 512MB @jerpi_bilbo

    - by hinkmond
    To keep our multiple Raspberry Pi boards apart from each other, I've now named my RPi Model B w/512MB: "jerpi_bilbo", which stands for Java Embedded Raspberry Pi - Bilbo (named after the Hobbit from the J.R.R. Tolkien stories). I also, set up a Twitter account for him. You can follow him at: @jerpi_bilbo He's self-tweeting, manual prompted so far (using Java Embedded 7.0 and twitter4j Java library). Works great! I'm setting him up to be automated self-tweeting soon, so watch for that... Here's a pointer to the open source twitter4j Java library: download here Just unzip and extract out the twitter4j-core-2.2.6.jar and put it on your Java Embedded classpath. Here's how @jerpi_bilbo uses it to Tweet with his Java Embedded runtime: import twitter4j.*; import java.io.* public final class Tweet { public static void main(String[] args) { String statusStr = null; if ((args.length 0) && (args[0] != null)) { statusStr = args[0]; } else { statusStr = new String("Hello World!"); } // Create new instance of the Twitter class Twitter twitter = new TwitterFactory().getInstance(); try { Status status = twitter.updateStatus(statusStr); System.out.println ("Successfully updated the status to: " + status.getText()); } catch (Exception e) { e.printStackTrace(); } } } That's all you need. Java Embedded rocks the RPi! And, @jerpi_bilbo is alive... Hinkmond

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

  • Sound Complete Not Firing (AS3)

    - by JasonMc92
    I have a bit of a quandary. I need to call a function inside a MovieClip once a particular sound has finished playing. The sound is played via a sound channel in an external class which I have imported. Playback is working perfectly. Here is the relevent code from my external class, Sonus. public var SFXPRChannel:SoundChannel = new SoundChannel; var SFXPRfishbeg:Sound = new sfxpr_fishbeg(); var SFXPRfishmid:Sound = new sfxpr_fishmid(); var SFXPRfishend3:Sound = new sfxpr_fishend3(); var SFXPRfishend4:Sound = new sfxpr_fishend4() public function PlayPrompt(promptname:String):void { var sound:String = "SFXPR" + promptname; SFXPRChannel = this[sound].play(); } This is called via an import in the document class "osr", thus I access it in my project via "osr.Sonus.---" In my project, I have the following line of code. osr.Sonus.SFXPRChannel.addEventListener(Event.SOUND_COMPLETE, promptIsFinished); function prompt():void { var level = osr.Gradua.Fetch("fish", "arr_con_level"); Wait(true); switch(level) { case 1: osr.Sonus.PlayPrompt("fishbeg"); break; case 2: osr.Sonus.PlayPrompt("fishmid"); break; case 3: osr.Sonus.PlayPrompt("fishend3"); break; case 4: osr.Sonus.PlayPrompt("fishend4"); break; } } function Wait(yesno):void { gui.Wait(yesno); } function promptIsFinished(evt:Event):void { Wait(false); } osr.Sonus.PlayPrompt(...) and gui.Wait(...) both work perfectly, as I use them in other contexts in this part of the project without error. Basically, after the sound finishes playing, I need Wait(false); to be called, but the event listener does not appear to be "hearing" the SOUND_COMPLETE event. Did I make a mistake somewhere? For the record, due to my project structure, I cannot call the appropriate Wait(...) function from within Sonus. Help?

  • AudioTrack lag: obtainBuffer timed out

    - by BTR
    I'm playing WAVs on my Android phone by loading the file and feeding the bytes into AudioTrack.write() via the FileInputStream BufferedInputStream DataInputStream method. The audio plays fine and when it is, I can easily adjust sample rate, volume, etc on the fly with nice performance. However, it's taking about two full seconds for a track to start playing. I know AudioTrack has an inescapable delay, but this is ridiculous. Every time I play a track, I get this: 03-13 14:55:57.100: WARN/AudioTrack(3454): obtainBuffer timed out (is the CPU pegged?) 0x2e9348 user=00000960, server=00000000 03-13 14:55:57.340: WARN/AudioFlinger(72): write blocked for 233 msecs, 9 delayed writes, thread 0xba28 I've noticed that the delayed write count increases by one every time I play a track -- even across multiple sessions -- from the time the phone has been turned on. The block time is always 230 - 240ms, which makes sense considering a minimum buffer size of 9600 on this device (9600 / 44100). I've seen this message in countless searches on the Internet, but it usually seems to be related to not playing audio at all or skipping audio. In my case, it's just a delayed start. I'm running all my code in a high priority thread. Here's a truncated-yet-functional version of what I'm doing. This is the thread callback in my playback class. Again, this works (only playing 16-bit, 44.1kHz, stereo files right now), it just takes forever to start and has that obtainBuffer/delayed write message every time. public void run() { // Load file FileInputStream mFileInputStream; try { // mFile is instance of custom file class -- this is correct, // so don't sweat this line mFileInputStream = new FileInputStream(mFile.path()); } catch (FileNotFoundException e) {} BufferedInputStream mBufferedInputStream = new BufferedInputStream(mFileInputStream, mBufferLength); DataInputStream mDataInputStream = new DataInputStream(mBufferedInputStream); // Skip header try { if (mDataInputStream.available() > 44) mDataInputStream.skipBytes(44); } catch (IOException e) {} // Initialize device mAudioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, ConfigManager.SAMPLE_RATE, AudioFormat.CHANNEL_CONFIGURATION_STEREO, AudioFormat.ENCODING_PCM_16BIT, ConfigManager.AUDIO_BUFFER_LENGTH, AudioTrack.MODE_STREAM); mAudioTrack.play(); // Initialize buffer byte[] mByteArray = new byte[mBufferLength]; int mBytesToWrite = 0; int mBytesWritten = 0; // Loop to keep thread running while (mRun) { // This flag is turned on when the user presses "play" while (mPlaying) { try { // Check if data is available if (mDataInputStream.available() > 0) { // Read data from file and write to audio device mBytesToWrite = mDataInputStream.read(mByteArray, 0, mBufferLength); mBytesWritten += mAudioTrack.write(mByteArray, 0, mBytesToWrite); } } catch (IOException e) { } } } } If I can get past the artificially long lag, I can easily deal with the inherit latency by starting my write at a later, predictable position (ie, skip past the minimum buffer length when I start playing a file).

  • Context Sensitive JTable (Part 2)

    - by Geertjan
    Now, having completed part 1, let's add a popup menu to the JTable. However, the menu item in the popup menu should invoke the same Action as invoked from the toolbar button created yesterday. Add this to the constructor created yesterday: Collection<? extends Action> stockActions =         Lookups.forPath("Actions/Stock").lookupAll(Action.class); for (Action action : stockActions) {     popupMenu.add(new JMenuItem(action)); } MouseListener popupListener = new PopupListener(); // Add the listener to the JTable: table.addMouseListener(popupListener); // Add the listener specifically to the header: table.getTableHeader().addMouseListener(popupListener); And here's the standard popup enablement code: private JPopupMenu popupMenu = new JPopupMenu(); class PopupListener extends MouseAdapter { @Override public void mousePressed(MouseEvent e) { showPopup(e); } @Override public void mouseReleased(MouseEvent e) { showPopup(e); } private void showPopup(MouseEvent e) { if (e.isPopupTrigger()) { popupMenu.show(e.getComponent(), e.getX(), e.getY()); } } }

  • How to compare DateTime Objects while looping through a list?

    - by Taniq
    I'm trying to loop through a list (csv) containing two fields; a name and a date. There are various duplicated names and various dates in the list. I'm trying to deduce for each name in the list, where there are multiple instances of the same name, which corresponding date is the latest. I realise, from looking at another answer, that I need to use the DateTime.Compare method which is fine, but my problem is working out which date is later. Once I know this I need to produce a file with unique names and the latest date relating to it. This is my first question which makes me a newbie. EDIT: Initially I thought it would be 'ok' to set the LatestDate object to a date that wouldn't show up in my file, therefore making any later dates in the file the LatestDate. Here's my coding so far: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace flybe_overwriter { class Program { static DateTime currentDate; static DateTime latestDate = new DateTime(1000,1,1); static HashSet<string> uniqueNames = new HashSet<string>(); static string indexpath = @"e:\flybe test\indexing.csv"; static string[] indexlist = File.ReadAllLines(indexpath); static StreamWriter outputfile = new StreamWriter(@"e:\flybe test\match.csv"); static void Main(string[] args) { foreach (string entry in indexlist) { uniqueNames.Add(entry.Split(',')[0]); } HashSet<string>.Enumerator fenum = new HashSet<string>.Enumerator(); fenum = uniqueNames.GetEnumerator(); while (fenum.MoveNext()) { string currentName = fenum.Current; foreach (string line in indexlist) { currentDate = new DateTime(Convert.ToInt32(line.Split(',')[1].Substring(4, 4)), Convert.ToInt32(line.Split(',')[1].Substring(2, 2)), Convert.ToInt32(line.Split(',')[1].Substring(0, 2))); if (currentName == line.Split(',')[0]) { if(DateTime.Compare(latestDate.Date, currentDate.Date) < 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is earlier than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) > 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is later than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) == 0) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is the same as " + currentDate.ToShortDateString()); } } } } } } } Any help appreciated. Thanks.

  • Distribution upgrade freezes

    - by lugte098
    When upgrading from Ubuntu 10.04 to 10.10 the distribution upgrade program freezes after it notifies me of a change in /etc/apparmor.d/usr.bin.mysqld and asks me to keep the old file or accept the new changes (I accepted them). The terminal says: Configuration file `/etc/apparmor.d/usr.sbin.mysqld' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** usr.sbin.mysqld (Y/I/N/O/D/Z) [default=N] ? y Installing new version of config file /etc/apparmor.d/usr.sbin.mysqld ... The program hasn't done anything after this for about 2 hours now and I have no idea what I should do at this point. Can I quit the program and restart it? Or is there another action I should take? It did however change the '/etc/apparmor.d/usr.sbin.mysqld' to the new version, but is still frozen...

  • Very simple test view in MonoTouch draws a line using Core Graphics but view content is not shown

    - by Krumelur
    Hi, I give up now on this very simple test I've been trying to run. I want to add a subview to my window which does nothing but draw a line from one corner of the iPhone's screen to the other and then, using touchesMoved() it is supposed to draw a line from the last to the current point. The issues: 1. Already the initial line is not visible. 2. When using Interface Builder, the initial line is visible, but drawRect() is never called, even if I call SetNeedsDisplay(). It can't be that hard...can somebody fix the code below to make it work? In main.cs in FinishedLaunching(): oView = new TestView(); oView.AutoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight; oView.Frame = new System.Drawing.RectangleF(0, 0, 320, 480); window.AddSubview(oView); window.MakeKeyAndVisible (); The TestView.cs: using System; using MonoTouch.UIKit; using MonoTouch.CoreGraphics; using System.Drawing; using MonoTouch.CoreAnimation; using MonoTouch.Foundation; namespace Test { public class TestView : UIView { public TestView () : base() { } public override void DrawRect (RectangleF area, UIViewPrintFormatter formatter) { CGContext oContext = UIGraphics.GetCurrentContext(); oContext.SetStrokeColor(UIColor.Red.CGColor.Components); oContext.SetLineWidth(3.0f); this.oLastPoint.Y = UIScreen.MainScreen.ApplicationFrame.Size.Height - this.oLastPoint.Y; this.oCurrentPoint.Y = UIScreen.MainScreen.ApplicationFrame.Size.Height - this.oCurrentPoint.Y; oContext.StrokeLineSegments(new PointF[] {this.oLastPoint, this.oCurrentPoint }); oContext.Flush(); oContext.RestoreState(); Console.Out.WriteLine("Current X: {0}, Y: {1}", oCurrentPoint.X.ToString(), oCurrentPoint.Y.ToString()); Console.Out.WriteLine("Last X: {0}, Y: {1}", oLastPoint.X.ToString(), oLastPoint.Y.ToString()); } private PointF oCurrentPoint = new PointF(0, 0); private PointF oLastPoint = new PointF(320, 480); public override void TouchesMoved (MonoTouch.Foundation.NSSet touches, UIEvent evt) { base.TouchesMoved (touches, evt); UITouch oTouch = (UITouch)touches.AnyObject; this.oCurrentPoint = oTouch.LocationInView(this); this.oLastPoint = oTouch.PreviousLocationInView(this); this.SetNeedsDisplay(); } } }

  • Another Spring + Hibernate + JPA question

  • Tips for Making this Code Testable [migrated]

    - by Jesse Bunch
    So I'm writing an abstraction layer that wraps a telephony RESTful service for sending text messages and making phone calls. I should build this in such a way that the low-level provider, in this case Twilio, can be easily swapped without having to re-code the higher level interactions. I'm using a package that is pre-built for Twilio and so I'm thinking that I need to create a wrapper interface to standardize the interaction between the Twilio service package and my application. Let us pretend that I cannot modify this pre-built package. Here is what I have so far (in PHP): <?php namespace Telephony; class Provider_Twilio implements Provider_Interface { public function send_sms(Provider_Request_SMS $request) { if (!$request->is_valid()) throw new Provider_Exception_InvalidRequest(); $sms = \Twilio\Twilio::request('SmsMessage'); $response = $sms->create(array( 'To' => $request->to, 'From' => $request->from, 'Body' => $request->body )); if ($this->_did_request_fail($response)) { throw new Provider_Exception_RequestFailed($response->message); } $response = new Provider_Response_SMS(TRUE); return $response; } private function _did_request_fail($api_response) { return isset($api_response->status); } } So the idea is that I can write another file like this for any other telephony service provided that it implements Provider_Interface making them swappable. Here are my questions: First off, do you think this is a good design? How could it be improved? Second, I'm having a hard time testing this because I need to mock out the Twilio package so that I'm not actually depending on Twilio's API for my tests to pass or fail. Do you see any strategy for mocking this out? Thanks in advance for any advice!

  • jQuery replacing an image inside a .net datalist

    - by user359409
    (submit said I was trying to post an image so I've changed image everywhere to ix I am trying to get jQuery to replace an ix inside a datalist. The original ix is the thumbnail ix of a product on a category page. The small ix I am clicking on are swatch ix for the different colors of a product. I can get it to work using a div tag around the ix tag inside the ItemTemplate. I don't need to use a div tag if I can get the imagesx to swap- I was just using it because that is sample code I found and it works for the first product in the category. <asp:HyperLink ID="ProductNav" runat="server" NavigateUrl='<%#Eval("NavigateUrl") %>'> <div id="ladiv" runat="server"> <asp:Ixx runat="server" ID="ProdThumb" /> </div> </asp:HyperLink> <asp:PlaceHolder ID="phSwatches" runat="server"></asp:PlaceHolder> The ProdThumb ix is added from the code behind and the swatches are added from the code behind swatches.Controls.Add(new LiteralControl("<table><tr>")); foreach(OptionChoice optionChoice in option.Choices) { string swatchThumbnail = string.Format("<ix ID=\"{0}\" src=\"{1}\" border=\"0\" class=\"{2}\" />","swatch" + optionChoice.OptionChoiceId.ToString(), ResolveUrl(optionChoice.ThumbnailUrl),"imgthumb"); swatches.Controls.Add(new LiteralControl("<td>")); swatches.Controls.Add(new LiteralControl(swatchThumbnail)); swatches.Controls.Add(new LiteralControl("</td>")); } swatches.Controls.Add(new LiteralControl("</tr></table>")); prodThumb.IxUrl = product.ThumbnailUrl; prodThumb.AlternateText = product.ThumbnailAltText; prodThumb.CssClass = "Thumbnail"; The jQuery is: $(function() { $("ix.imgthumb").click(function(e) { var t = $(this); var newImg = ''; $('#ladiv') .html($(newImg) ); }); }); </script> Both images are named similar, except the swatch contains "sws" and the larger one is the some only with "swl". I have spent several days searching but am not able to get it to work. If I try something like $("#<%=ladiv.ClientID %") the code can't find it. I appreciate any help.

  • Farseer Physics Samples and Krypton how to reference game

    - by Krell
    I'm sure this is totally simple and yes I am new at this. I am trying to set up Krypton inside farseer. 1. create a new Krypton engine in my sub screen aka AdvancedDemo1 : PhysicsGameScreen, IDemoScreen Via this.krypton = new KryptonEngine(this, "KryptonEffect"); The problem is the KryptonEngine(this wants reference to Game game, I cant seem to reference it from FarseerPhysicsGame : Game So how would I do that? or 2. I can put it directly in FarsserPhysicsGame but again I cant seem to figure out how to reference FarseerPhysicsGame in AdvancedDemo1. or 3. I can put it inside the public FarseerPhysicsGame() and do Componenets.Add(krypton) [which works] HOWEVER I cant figure out how to reference the compoenet once it is added. You should be able to stop reading here , but for more detail I simply took the Farseer XNA Samples went into FarseerPhysicsGame.cs and deleted all the screens and menus except AdvancedDemo1 so there is one option and I just click that to load into the advancedDemo1 and thats where I want to put the lights from krypton. Thanks. Edit: Figured out 1 solution though I am still curious about others. Solution 1 I was able to use ScreenManager.Game(not sure why it was there but Ill try to figure it out later)

  • Is it any loose coupling mechanism in Objective-C + Cocoa like C# delegates or C++Qt signals+slots?

    - by Eye of Hell
    Hello. For a large programs, the standard way to chalenge a complexity is to divide a program code into small objects. Most of the actual programming languages offer this functionality via classes, so is Objective-C. But after source code is separated into small object, the second challenge is to somehow connect them with each over. Standard approaches, supported by most languages are compositon (one object is a member field of another), inheritance, templates (generics) and callbacks. More cryptic techniques include method-level delagates (C#) and signals+slots (C++Qt). I like the delegates / signals idea, since while connecting two objects i can connect individual methods with each over, without objects knowing anything of each over. For C#, it will look like this: var object1 = new CObject1(); var object2 = new CObject2(); object1.SomethingHappened += object2.HandleSomething; In this code, is object1 calls it's SomethingHappened delegate (like a normal method call) the HandleSomething method of object2 will be called. For C++Qt, it will look like this: var object1 = new CObject1(); var object2 = new CObject2(); connect( object1, SIGNAL(SomethingHappened()), object2, SLOT(HandleSomething()) ); The result will be exactly the same. This technique has some advantages and disadvantages, but generally i like it more than interfaces since if program code base grows i can change connections and add new ones without creating tons of interfaces. After examination of Objective-C i havn't found any way to use this technique i like :(. It seems that Objective-C supports message passing perfectly well, but it requres for object1 to have a pointer to object2 in order to pass it a message. If some object needs to be connected to lots of other objects, in Objective-C i will be forced to give him pointers to each of the objects it must be connected. So, the question :). Is it any approach in Objective-C programming that will closely resemble delegate / signal+slot types of connection, not a 'give first object an entire pointer to second object so it can pass a message to it'. Method-level connections are a bit more preferable to me than object-level connection ^_^.

  • Actionscript - Dropping Multiple Objects Using an Array? [closed]

    - by Eratosthenes
    Possible Duplicate: Actionscript - Dropping Multiple Objects Using an Array? I'm trying to get these fireBalls to drop more often, im not sure if im using Math.random correctly also, for some reason I'm getting a null reference because I think the fireBalls array waits for one to leave the stage before dropping another one? this is the relevant code: var sun:Sun=new Sun var fireBalls:Array=new Array() var left:Boolean; function onEnterFrame(event:Event){ if (left) { sun.x = sun.x - 15; }else{ sun.x = sun.x + 15; } if (fireBalls.length>0&&fireBalls[0].y>stage.stageHeight){ // Fireballs exit stage removeChild(fireBalls[0]); fireBalls.shift(); } for (var j:int=0; j<fireBalls.length; j++){ fireBalls[j].y=fireBalls[j].y+15; if (fireBalls[j].y>stage.stageHeight-fireBall.width/2){ } } if (Math.random()<.2){ // Fireballs shooting from Sun var fireBall:FireBall=new FireBall; fireBall.x=sun.x; addChild(fireBall); fireBalls.push(fireBall); } }

  • WINAPI window management question

    - by gekod
    I'm learning to develop windows applications using WINAPI and plain C. Now I got a bit confused with all those handles and would like to ask if you guys could teach me some good practices to structure and handle controls and windows. Here's where I get confused: Using the IDs declared in the resources for each object, we can get their handles using GetDlgItem(). Now what if we don't know their parent, which is needed by this function. One example: We have the main window created at launch. Then we register two new window classes and create a window for each new class and we create a message function for each too. Now if inside one of the children windows I create a button and inside the other child window I create a text label. Now when we click the button inside of child window A the label in child window B shall be modified to whatever. The WM_COMMAND for the button is interpreted inside the message loop for child window A. Now what would be the best and more elegant way to access the text label inside the child window B? I am in the process of learning the WINAPI and just want to learn it right from the start instead of producing Hacked code that someday becomes unreadable and to later have to adapt to a new way of programing.

  • How come there is still so much programming work?

    - by jd_505
    First I'd like to say that I am not pretty sure that this question will meet the guidelines. I think it can goes under the "Freelancing and business concerns" bullet, but I am not sure. Anyway, I will give it a shot. I wonder how the programming jobs hasn't yet "dried" because of the software evolution, for example, I am a developer myself, which means that I do care about software (I mean I am not of the type of guys that needs a computer mainly to just browse the Internet), and still I wouldn't mind if I never receive any more updates on my Ubuntu machine. I find that it provides everything I need, and while the updates provide various bug fixes/improvements, I wouldn't mind using it with it's current state for the rest of my life, for 2 years of Ubuntu usage I have never bumped at a serious bug/problem. Another example is Windows, almost half of it's users still use XP, which is practically ancient, yet they find it satisfying all their needs (and I agreee with them). I could go with many more examples, but by now you are understanding my point and my question. While new "trends" appears all of the time (like a new mobile OS) which runs on new platforms and requires some fresh development work, still the majority of the software effort goes in to what I consider as "completed projects", or at least a state of a project which is enough to be considered as completed. Do you have an explanation ? I can't think of the right tags for this question, please edit it the way you find it to be most appropriate. Thanks.

  • Hosting woes

    Unfortunately quite a few people have noticed our recent hosting problems, but if you are reading this they should all be over, so please accept our apologies. Our former web host decided migrate to a new platform, it had all sorts or great features, but on reflection hosting wasn’t one of them. We knew it was coming, and had even been proactive and requested several dates on their migration control panel so I could be around to check it afterwards. The dates came and went without anything happening, so we sat back and carried on on for a couple of months thinking they’d get back to us when they were ready. Then out of the blue I get an email saying it has happened! Now this is what I call timing, I had client work to complete, a 50 minute presentation to write and there was a little conference called SQLBits that I help organise at the end of the week, and then our hosting provider decides to migrate our sites. Unfortunately they only migrated parts of the sites, they forgot things like the database for SQLDTS. The database eventually appeared, but the data didn’t. Then the data pitched up but without the stored procedures. I was even asked if I could perform a backup and send it to them, as they were getting timeout errors. Never mind the issues of performing a native backup on a hosted server, whilst I could have done something, the question actually left me speechless. So you cannot access your own SQL server and you expect me to be able to help? This site was there, but hadn’t been set as an IIS application so all path references were wrong which meant no CSS and all the internal navigation and links were wrong. The new improved hosting platform Control Panel didn't appear to like setting applications. It said it would, you’d have to wait 2 hours of course, then just decided not to bother after all. So needless to say after a very successful SQLBits I focused my attention on finding a new web host, and here we are again. Sorry it took so long.

  • onDateSet does not get called from DatePickerDialog on tablet

    - by cit
    I am using a DatePickerDialog to prompt the user for a date. It works fine in the simulator and on my Samsung Galaxy Nexus, but onDateSet does not get called on my Samsung Galaxy Tab 2. I noticed, that the dialog is bigger and shows a calendar besides the normal spin view. Can that be the problem? Here is some code: import java.util.Calendar; import java.util.Date; import android.app.DatePickerDialog; import android.app.Dialog; import android.content.DialogInterface; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.DialogFragment; import android.widget.DatePicker; import com.cbit.gtbetapp.R; import com.cbit.gtbetapp.gui.racedata.MeetingDataActivity; import com.cbit.gtbetapp.gui.racedata.MeetingListFragment; import com.cbit.gtbetapp.logic.Utility; public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { protected Date date = null; @Override public Dialog onCreateDialog(Bundle savedInstanceState) { // Use the current date as the default date in the picker final Calendar c = Utility.getToday(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH); int day = c.get(Calendar.DAY_OF_MONTH); date = c.getTime(); // Create a new instance of DatePickerDialog and return it DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day) { @Override public void onDateChanged(DatePicker view, int year, int month, int day) { super.onDateChanged(view, year, month, day); setTitle(getString(R.string.date_picker_title)); } }; dialog.setTitle(getString(R.string.date_picker_title)); dialog.setButton(DatePickerDialog.BUTTON_POSITIVE, getString(android.R.string.ok), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); Intent intent = new Intent(getActivity(), MeetingDataActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); intent.putExtra(MeetingListFragment.EXTRA_DATE, date.getTime()); startActivity(intent); } }); dialog.setButton(DatePickerDialog.BUTTON_NEGATIVE, getString(R.string.button_cancel), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); return dialog; } public void onDateSet(DatePicker view, int year, int month, int day) { Calendar c = Calendar.getInstance(); c.clear(); c.set(Calendar.YEAR, year); c.set(Calendar.MONTH, month); c.set(Calendar.DAY_OF_MONTH, day); date = c.getTime(); } } What could cause this? A bug in the tablet? Am I missing something? Can anyone think of a workaround? Thanks a lot!

  • Threadpool with pasistant worker instances

    - by Matt Smokey-waters Holmes
    So basically what im trying to do is queue up tasks in a thread pool to be executed as soon as a worker becomes free, i have found various examples of this but in all cases the examples have been setup to use a new Worker instance for each job, i want persistent workers. Im trying to make a ftp backup tool, i have it working but because of the limitations of a single connection it is slow. What i ideally want to do is have a single connection for scanning directories and building up a file list then four workers to download said files. Here is an example of my worker /** * FTP Worker */ public class Worker implements Runnable { protected FTPClient _ftp; // Connection details protected String _host = ""; protected String _user = ""; protected String _pass = ""; // worker status protected boolean _working = false; public Worker(String host, String user, String pass) { this._host = host; this._user = user; this._pass = pass; } // Check if the worker is in use public boolean inUse() { return this._working; } @Override public void run() { this._ftp = new FTPClient(); this._connect(); } // Download a file from the ftp server public boolean download(String base, String path, String file) { this._working = true; boolean outcome = true; //create directory if not exists File pathDir = new File(base + path); if (!pathDir.exists()) { pathDir.mkdirs(); } //download file try { OutputStream output = new FileOutputStream(base + path + file); this._ftp.retrieveFile(file, output); output.close(); } catch (Exception e) { outcome = false; } finally { this._working = false; return outcome; } } // Connect to the server protected boolean _connect() { try { this._ftp.connect(this._host); this._ftp.login(this._user, this._pass); } catch (Exception e) { return false; } return this._ftp.isConnected(); } // Disconnect from the server protected void _disconnect() { try { this._ftp.disconnect(); } catch (Exception e) { /* do nothing */ } } } and basically i want to be able to call Worker.download(...) for each task in a queue whenever a worker becomes available without having to create a new connection to the ftp server for each download Any help would be appreciated as iv'e never used threads before and I'm going round in circles at the moment

  • How much sense does it make for a veteran .Net developer to move to ROR professionally?

    - by SharePoint Newbie
    Hi, I consider myself a moderately skilled (definitely not stupid) .Net developer. Over the past 5 years I've been working with ASP.Net, ASP.Net MVC, SharePoint, WPF, Silverlight, RDBMS (SQL Server and Oracle). I maintain/contribute a couple of .Net OSS. I've also picked up F# and Haskell over the previous year. I am currently employed at one of the better (best) software firms out there and would surely love to continue working here. However over the past 6 months opportunities in .Net have mostly dried up and all new work is headed towards ROR (and whatever is left towards Java). I have never been apprehensive about learning a new stack/language for fun and have previously picked up Haskell and Python in my free time. I am however apprehensive as to what impact moving to a new entirely different stack would have on my career. What would you do: Change jobs if you don't find anything on .Net soon. Try out the ROR stack for some time. If you find that its not your cup of tea, move back. (How would this impact my career and job opportunities in the longer run?) Also it would be very helpful if there are any ASP.Net MVC folks who have switched over to ROR professionally who can share their experiences. Edit: I have not done any development on a *nix box before. I've however used Ubuntu for fun and games. Sorry if this sounds subjective.
