• Changing timezone without changing time in Java

  - by Martin

  Hi! I'm receiving a datetime from a SOAP webservice without timzone information. Hence, the Axis deserializer assumes UTC. However, the datetime really is in Sydney time. I've solved the problem by substracting the timezone offset: Calendar trade_date = trade.getTradeDateTime(); TimeZone est_tz = TimeZone.getTimeZone("Australia/Sydney"); long millis = trade_date.getTimeInMillis() - est_tz.getRawOffset(); trade_date.setTimeZone( est_tz ); trade_date.setTimeInMillis( millis ); However, I'm not sure if this solution also takes daylight saving into account. I think it should, because all operations are on UTC time. Any experiences with manipulating time in Java? Better ideas on how to solve this problem?

• How to save some values from an array in a controller in Rails?

  - by Alfred Nerstu

  I've got a links array that I'm saving to a database. The problem is that the records aren't saved in the order of the array ie links[1] is saved before links[2] and so on... This is a example from the view file: <p> <label for="links_9_label">Label</label> <input id="links_9_name" name="links[9][name]" size="30" type="text" /> <input id="links_9_url" name="links[9][url]" size="30" type="text" /> </p> And this is my controller: def create @links = params[:links].values.collect { |link| @user.links.new(link) } respond_to do |format| if @links.all?(&:valid?) @links.each(&:save!) flash[:notice] = 'Links were successfully created.' format.html { redirect_to(links_url) } else format.html { render :action => "new" } end end end Thanks in advance!

• Best way to save complex Python data structures across program sessions (pickle, json, xml, database

  - by Malcolm

  Looking for advice on the best technique for saving complex Python data structures across program sessions. Here's a list of techniques I've come up with so far: pickle/cpickle json jsonpickle xml database (like SQLite) Pickle is the easiest and fastest technique, but my understanding is that there is no guarantee that pickle output will work across various versions of Python 2.x/3.x or across 32 and 64 bit implementations of Python. Json only works for simple data structures. Jsonpickle seems to correct this AND seems to be written to work across different versions of Python. Serializing to XML or to a database is possible, but represents extra effort since we would have to do the serialization ourselves manually. Thank you, Malcolm

  This could be very basic type of question for you! But for me it is very important. 1) How these(orkut, facebook or other) website store the images in server? Options: a) Keeping all the images in database by converting into bytecode/binary. b) Making a new folder for each user and saving photographs according to their library name. c) Or something else which i(Anup) didn't guess yet. Please reply me. Sayiing thanx to see my question and any many many thanx for answering my question.

• Mixing JQuery Ajax with ASP.NET : is there any security risk

  - by Sayem Ahmed

  I am using jQuery with ASP.NET in a project. Instead of using ASP.NET Ajax, I am using jquery's ajax functions. Is there any security risk if I do that? I mean, since I am using jquery's ajax calls, no view state information will be passed to the server so that it can verify the page's authenticity (though it saves a lot of bandwidth..). I would also like to know what is the best/good practice here.

• How can I determine file encodings on Windows / IIS ?

  - by Dylan Beattie

  From the answers to this question it appears there's a file somewhere on our server that's been saved with the wrong encoding. I've seen this happen before - most often when pasting from Word into Visual Studio, when "smart quotes" can interfere with Visual Studio's encoding settings when saving the file. Thing is - the problem I'm having involves 20-30 different script files, include files and so on (hey, that was how we kept it modular back in the day...) and I really don't want to open every one of them in Visual Studio and check the file encodings individually. Is there any way I can analyze a folder tree full of files and spit out a list of each filename along with the text encoding used to save the file? (Or - if encodings aren't clearly specified - work out what encoding Microsoft IIS thinks was used to save the file?)

• Migrating C# code from Cassandra .5 to .6

  - by Jonathan

  I have some some simple code derived from an example that is meant to form a quick write to the Cassandra db, then loop back and read all current entries, everything worked fine. When .6 came out, i upgraded Cassandra and thrift, which threw errors in my code (www[dot]copypastecode[dot]com/26760/) - i was able to iron out the errors by converting the necessary types, however in the version that compiles now only seems to read one item back, im not sure if its not saving db changes or if its only reading back 1 entry. the "fixed" code is here: http://www.copypastecode.com/26752/. Any help would be greatly appreciated.

• Java postal address parser

  Somewhat related to this question, but in the absence of any answer about QuickBooks specifically, does anyone knows of an address parser for Java. Something that can take unstructured address information and parse out the address line 1, 2 and city state postal code and country?

• Lamp with mod_fastcgi

  - by Jonathan

  Hi! I am building a cgi application, and now I would like it to be like an application that stands and parses each connection, with this, I can have all session variables saved in memory instead of saving them to file(or anyother place) and loading them again on a new connection I am using lamp within a linux vmware but I can't seem to find how to install the module for it to work and what to change in the httpd.conf. I tried to compile the module, but I couldn't because my apache isn't a regular instalation, its a lamp already built one, and it seems that the mod needs the apache directory to be compiled. I saw some coding examples out there, so I guess is not that hard once its runing ok with Apache Can you help me with this please? Thanks, Joe

• Java JFileChooser getAbsoluteFile Add File Extension

  - by ikurtz

  i have this issue working but i would like to know if there is a better way of adding the file extension? what i am doing right now is: String filePath = chooser.getSelectedFile().getAbsoluteFile() + ".html"; im adding the extension hard coded. and then saving to it. just wondering if there is a more robust/logical manner this can be implemented? thank you for your time. EDIT: i ask this as i would like my app to be portable across platforms. so adding .html manually i may make this a windows only solution.

• C#/.NET: Separation of multipage tiff with compression "CCITT T.6" very slow

  - by Alex B

  I need to separate multiframe tiff files, and use the following method: public static Image[] GetFrames(Image sourceImage) { Guid objGuid = sourceImage.FrameDimensionsList[0]; FrameDimension objDimension = new FrameDimension(objGuid); int frameCount = sourceImage.GetFrameCount(objDimension); Image[] images = new Image[frameCount]; for (int i = 0; i < frameCount; i++) { MemoryStream ms = new MemoryStream(); sourceImage.SelectActiveFrame(objDimension, i); sourceImage.Save(ms, ImageFormat.Tiff); images[i] = Image.FromStream(ms); } return images; } It works fine, butt if the source was encoded using the CCITT T.6 compression, separating a 20-frame-file takes up to 15 seconds on my 2,5ghz CPU. Saving the images afterwards to a single file using standard compression (LZW), the separation time is under 1 second. Is there a way to speed up the process?

• When using delegates, need better way to do sequential processing

  - by Padawan

  I have a class WebServiceCaller that uses NSURLConnection to make asynchronous calls to a web service. The class provides a delegate property and when the web service call is done, it calls a method webServiceDoneWithXXX on the delegate. There are several web service methods that can be called, two of which are say GetSummary and GetList. The classes that use WebServiceCaller initially need both the summary and list so they are written like this: -(void)getAllData { [webServiceCaller getSummary]; } -(void)webServiceDoneWithGetSummary { [webServiceCaller getList]; } -(void)webServiceDoneWithGetList { ... } This works but there are at least two problems: The calls are split across delegate methods so it's hard to see the sequence at a glance but more important it's hard to control or modify the sequence. Sometimes I want to call just GetSummary and not also GetList so I would then have to use an ugly class-level state variable that tells webServiceDoneWithGetSummary whether to call GetList or not. Assume that GetList cannot be done until GetSummary completes and returns some data which is used as input to GetList. Is there a better way to handle this and still get asynchronous calls? Update based on Matt Long's answer: Using notifications instead of a delegate, it looks like I can solve problem #2 by setting a different selector depending on whether I want the full sequence (GetSummary+GetList) or just GetSummary. Both observers would still use the same notification name when calling GetSummary. I would have to write two separate methods to handle GetSummaryDone instead of using a single delegate method (where I would have needed some class-level variable to tell whether to then call GetList). -(void)getAllData { [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getSummaryDoneAndCallGetList:)                  name:kGetSummaryDidFinish object:nil];     [webServiceCaller getSummary]; } -(void)getSummaryDoneAndCallGetList { [NSNotificationCenter removeObserver] //process summary data [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getListDone:)                  name:kGetListDidFinish object:nil];     [webServiceCaller getList]; } -(void)getListDone { [NSNotificationCenter removeObserver] //process list data } -(void)getJustSummaryData { [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getJustSummaryDone:) //different selector but                  name:kGetSummaryDidFinish object:nil]; //same notification name     [webServiceCaller getSummary]; } -(void)getJustSummaryDone { [NSNotificationCenter removeObserver] //process summary data } I haven't actually tried this yet. It seems better than having state variables and if-then statements but you have to write more methods. I still don't see a solution for problem 1.

• iPhone OpenGLES textures - colour banding

  - by chicknstu

  I've got a problem with openGL on iPhone which I'm sure must have a simple solution! When I load a texture and display it, I get a lot of what I believe is called 'Colour Banding', whereby the colours, particularly on gradients, seem to get automatically 'optimized'. Just to demonstrate that this wasn't anything wrong with my own code, I downloaded the iPhone 'Crashlanding' app and replaced the background image, and as you can see in the image below (Taken from the simulator), the exact same thing happens. The image on the left is the original PNG, and on the right is it in the game. It's almost as if it's palette is being downsized to a 256 colour one. Screenshot I'm sure this is related to the format I'm saving the image as, although it doesn't just happen with PNG's, it seems to happen no matter what image format I chose. Doing my head in! If you want to recreate this, simply download the crash landing app, and replace the background. Thanks so much in advance for any help.

• How to keep track of NSManagedObjects created in core-data persistently.

  - by KayKay

  In my application i am using core-data to store information and saving these data to the server using web-connectivity i have to use MySql. Basically what i want to do is to keep track of number of NSManagedObject already created and Whenever i am adding new NSManagedObject, based on that counting it will assign the class a Int_value which will act as primary_key in MySql. For examaple, there are already 10 NSManagedobjects, and when i will add new one it will assign it "11" as primary_key. these value will have to be increasing because there is no deleting of NSManagedObject. From my approach its about static member in applicationDelegate whose initial value can be any integer but should be incremented by one everytime new NSManagedObject is created and also it should be persistent. I am not clear how to do this, please give me suggestions. Thanks in advance.

• How triggers behave wrt concurrent visibility of transactions?

  - by stach

  I'm working on PostgreSQL 8.4 in read committed mode. I know that for each query, the server makes a snapshot of db state so that the query behaves consistently. Does it include triggers that are called in response to this query? Or is there a new snapshot created for each query called from within a trigger?

• UITableView Cell IndexPath

  - by Reonarudo

  Hello, Can anyone tell me how can I get a cell IndexPath? I was saving the IndexPath in the tableView: cellForRowAtIndexPath: method but this only loads when the cell is viewed and I need to know its index path on the viewDidLoad method. this resulted in a null value because as I said it only loads its value after the cell was viewed once. Thank you. EDIT The intention is being able to jump to a specific cell that has its specific number but its not linear with the sections and rows count.

• Calling 32 bit unmanaged dlls from C# randomly failing

  - by Bert

  Hi, I'm having an issue when calling 32 bit delphi dll's from c# web site. The code generally runs fine, but occasionally I get an error Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). This issue persists until I recycle the app pool for the site, and then it works fine again. On the same server, there is also a web service that is calling the same set of dlls. This web service doesn't seem to have the same issue that the web site has. Both applications are using .net framework 3.5, separate app pools on IIS. Here is the code I'm using to wrap the dlls: public sealed class Mapper { static Mapper instance = null; [DllImport("kernel32.dll")] private static extern bool SetDllDirectory(string lpPathName); private Mapper() { SetDllDirectory(ConfigManager.Path); } public static Mapper Instance { get { if (instance == null) { instance = new Mapper(); } return instance; } } public int Foo(string bar, ref double val) { return Loader.Foo(bar, ref val); } } public static class Loader { [DllImport("some.dll", CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode, EntryPoint = "foo")] public static extern int Foo(string bar, ref double val); } Then I call it like this: double val = 0.0; Mapper.Instance.Foo("bar", ref val); Any ideas as to why it would "randomly" Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). The other problem is that I haven't been able to replicate the issue in the development environment. I thought that due to 2 applications calling the same dlls, that there could be some locks occurring. To replicate this, I created an app that spawned multiple threads and repeatedly called the 32bit dlls, and then used the web site to call these same dlls. I still couldn't replicate the issue. Some possible fixes that I can think of: Wrap the 32 bit dlls in web service (because the webservice doesn't seem to suffer from the same problem). But this may be worthless if it turns out that the web service also fails. Set up state server for the session state and periodically recycle the app pool for the site.This isn't fixing the problem, only avoiding it. Wrap the dll's in exe, and call that exe. Then I shouldn't get the same issue. But this also seems like a hacky solution. Implement the mapper class differently ? But how else should I be doing the call? The other draw back is that other applications are using this mapper, so I'd need to change there code too. Thanks

• How to efficiently manage files on a filesystem in Java?

  - by Tuukka Mustonen

  I am creating a few JAX-WS endpoints, for which I want to save the received and sent messages for later inspection. To do this, I am planning to save the messages (XML files) into filesystem, in some sensible hierarchy. There will be hundreds, even thousands of files per day. I also need to store metadata for each file. I am considering to put the metadata (just a couple of fields) into database table, but the XML file content itself into files in a filesystem in order not to bloat the database with content data (that is seldomly read). Is there some simple library that helps me in saving, loading, deleting etc. the files? It's not that tricky to implement it myself, but I wonder if there are existing solutions? Just a simple library that already provides easy access to filesystem (preferrably over different operating systems). Or do I even need that, should I just go with raw/custom Java?

• Update image in ASP.NET page from memory without refreshing the page.

  - by ZeeMan

  I have a command line C# server and an ASP.NET client, they both communicate via .NET Remoting. The server is sending the client still images grabbed from a webcam at say 2 frames a second. I can pass the images down to the client via a remote method call and the image ends up in this client method: public void Update(System.Drawing.Image currentFrame) { // I need to display the currentFrame on my page. } How do i display the image on the a page without saving the image to the hard disc? If it was a winForms app i could pass currentFrame to a picturebox ie. picturebox.Image = currentFrame. The above Update method gets fired at least 2 times a second. If the client was a winForms app i could simply put picturebox.Image = currentFrame and the current frame on the screen would automatically get updated. How do i achieve the same effect with ASP.NET? Will the whole page need to be reloaded etc?

• How to implement dynamic changing password for this scenario?

  - by Mike108

  What is the Best practice of dynamic changing password for this scenario? The scenario is: There are three web apps using ASP.NET. App1 checks the passwords of app2/app3 to authenticate the identity, and if app2/app3 is authenticated then app1 is allowed to receive information from App2 and App3. And app1 has to change the passwords of app2/app3 every two hour for security reason. Is it possible that there is a way to implement this scenario without app1 saving the passwords of app2/app3 for security reason? Or is there any best practice for dynamic changing password scenario?
