• Handling Special char such as ^ÛY, ^ÛR in java

  - by RJ

  Hi, Has anybody encountered special char such as ^ÛY, ^ÛR ? Q1. How do I do an ftp of the files containing these chars? The chars are not seen once I do a ftp on AIX (bi or ascii) and hence I am unable to see my program to replace these, working. Q2. My java program doesn't seem to recognise these or replace these if I search for these explicitly (^ÛY, ^ÛR ) in the file however a replace using regular expression seems to work (I could only see the difference in the length of the string). My program is executed on AIX. Any insights why java cannot recognise these? Q3. Does the Oracle database recognise these chars? An update is failing where my program indicates the string to be of lesser length and without these characters but the db complains "value too large for column" as the string to be updated contains these chars and hence longer. thanks in advance, RJ

• in-memory database in Python

  - by Claudiu

  I'm doing some queries in Python on a large database to get some stats out of the database. I want these stats to be in-memory so other programs can use them without going to a database. I was thinking of how to structure them, and after trying to set up some complicated nested dictionaries, I realized that a good representation would be an SQL table. I don't want to store the data back into the persistent database, though. Are there any in-memory implementations of an SQL database that supports querying the data with SQL syntax?

• Combine static files or load in parallel

  - by Niall Collins

  I am at present introducing code to my site to combine css and javascript files. Is there a way without having to include an external library to load javascript asynchronously or in parallel? I have read on some blogs that combining of files can be counter productive as the load of the http request can be large and its better to load multiple files in parallel. Opinions on this? I am caching my javascript/css. And would have thought it was better to combine rather than have multiple http requests.

• Parallelism in Python

  - by fmark

  What are the options for achieving parallelism in Python? I want to perform a bunch of CPU bound calculations over some very large rasters, and would like to parallelise them. Coming from a C background, I am familiar with three approaches to parallelism: Message passing processes, possibly distributed across a cluster, e.g. MPI. Explicit shared memory parallelism, either using pthreads or fork(), pipe(), et. al Implicit shared memory parallelism, using OpenMP. Deciding on an approach to use is an exercise in trade-offs. In Python, what approaches are available and what are their characteristics? Is there a clusterable MPI clone? What are the preferred ways of achieving shared memory parallelism? I have heard reference to problems with the GIL, as well as references to tasklets. In short, what do I need to know about the different parallelization strategies in Python before choosing between them?

• iTunes Connect rejects my binary because I used a pre-release version of the SDK, what should I do?

  - by Prairiedogg

  NOTE - I'm posting this question to answer myself as a service to the community. Stay tuned for the answer. I downloaded a pre-release version of the iPhone SDK and tried to update one of my existing apps using a binary I built with it. Obviously you are not supposed to do this but I had forgotten about the warning when I installed the pre-release SDK. Anyway - I have two questions: Can I simply set the base SDK to an earlier version in the build settings and get around this problem? If not, then what should I do?

• iPhone Text entry with completion and DONE button (not search)

  - by Adam Jack

  Using iPhone SDK 3.0, I wish to allow text entry with (optional) completion options that appear as typing is occurring, i.e. also allowing freeformat entry. As such I am using a UISearchBar (which has the text change events) and a UISearchDisplayController to present options. The problems is I want the DONE button to say DONE and not SEARCH, however I cannot find a way to set that. Clearly I feel I am missing something, or Interface Builder of the SDK API would have some property to set. I have seen other apps (in the store) that have achieved the result I want (free format entry, completion, DONE button) so maybe there is an alternative approach I am missing. Thanks in advance for any pointers.

• iPad title bars. Navbars or toolbars?

  - by Squeegy

  I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles. So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

• Best way to get the iframe object.

  - by Umar Siddique

  Hi, We are using too many iframes in out web application. In these iframes we load the pages which may also contains iframes and so on up to N level. Right now i'm using recursive function to find out the required iframe object in JavaScript. It works fine, The issue is when we create large dynamic pages which may contains up to 1000 iframes in it. In this case my recursive function takes too much time to find the required iframe object. How i can overcome this issue or these is any alternative of recursion in JavaScript. Thanks

• MFMailComposerViewController doesn't always display attachments

  - by davbryn

  I'm attaching a few files to an email to export from the application I've written, namely a .pdf and a .png. I create these by rendering some view to a context and creating an image and a pdf. I can validate that the files are created properly (I can confirm this by looking in my apps sandbox from Finder, and also by sending the email. I receive the files correctly.) The problem I'm getting is that larger files don't have a preview generated for them within the MFMailComposerViewController view (I simply get a blue icon with a question mark). Is there a limitation on file sizes that can be attached in order for preview to function correctly? With small files it works as expected, but if I try and attach a pdf with the following properties: Pages: 1 Dimensions: 2414 x 1452 Size: 307 KB the file is generated correctly, but displays the question mark icon. If there is no way around that, can I remove the attachment preview altogether? Many thanks, Bryn

• Garbage collecting at ColdFusion CFC

  - by Sergii

  Hello. I have a CFC as singletone object in Application scope. One of the methods is used for massive data processing and periodically causes the "Java heap space" errors. EDIT All variables inside the method are VAR-scoped, so they should not be kept in the object scope when invokation ended. It can be a bit dumb question for Java people, but I'd like to know how Java garbage collector cleans up the CFC methods memory: only when whole request ends, or maybe right after each method/function invokation? Second option is interesting because it can allow me to split my large method into the few, as one of the possible optimizations.

• how to profile multi threaded c++ app on linux?

  - by anon

  I used to do all my linux profiling with gprof. However, with my multi threaded app, it's output appears to be inconsistent. Now, I dug this up http://sam.zoy.org/writings/programming/gprof.html howver, it's from a long time ago -- and in my gprof output, it appears my gprof is listing functions used by non-main threads. So, my questions are: 1) in 2010, can I easily use gprof to profile multi threaded linux c++ apps? (ubuntu 9.10) 2) what other tools should I look into for profiling? thanks!

• Performance logging tips

  - by Germstorm

  I am developing large data collecting ASP.Net/Windows service application-pair that uses Microsoft SQL Server 2005 through LINQ2Sql. Performance is always the issue. Currently the application is divided into multiple larger processing parts, each logging the duration of their work. This is not detailed and does not help us with anything. It would be nice to have some database tables that contain statistics that the application itself collected from its own behavior. What logging tips and data structures do you recommend to spot the parts that cause performance problems?

• Efficiency of checking for null varbinary(max) column ?

  - by Moe Sisko

  Using SQL Server 2008. Example table : CREATE table dbo.blobtest (id int primary key not null, name nvarchar(200) not null, data varbinary(max) null) Example query : select id, name, cast((case when data is null then 0 else 1 end) as bit) as DataExists from dbo.blobtest Now, the query needs to return a "DataExists" column, that returns 0 if the blob is null, else 1. This all works fine, but I'm wondering how efficient it is. i.e. does SQL server need to read in the whole blob to its memory, or is there some optimization so that it just does enough reads to figure out if the blob is null or not ? (FWIW, the sp_tableoption "large value types out of row" option is set to OFF for this example).

• Spring.NET. How actively is it being developed/supported?

  - by Bubba88

  I've made my choice for the developement components on the .NET platform: Spring.NET for IoC and NHibernate for data access. But how safe is it? I've heard here on SO (don't remember which post exactly) that Spring.NET is on its way down, cause for example the Java original version is developed by a large number of people; but (they say that) the sole person behind the .NET version is Mr. Mark Pollack. Is that so? And, if so, does it still make sense to count on Spring.NET for my production applications? if you have similar information about NHibernate, I'll appreciate it; though it seems that the latter is actively supported.

• Image coding library

  - by Dmitry

  Is there any good library for lossless image encoding/decoding that has compression rate more or less similar to PNG but decoding to raw RGB bitmap data would be much faster than PNG? Also alpha transparency is needed, but not essential because, alpha channel could be taken from separate image. Original problem lies in slowness of reading and decoding PNG files on iPhone using standard libraries. Obvious and the simples solution would have been storing raw RGB bitmap data, but then size of unpacked ipa is too large - 4 times larger than PNG files. So, I am trying to find some compromise solution.

• Can obfuscation (proguard) lead to MIDlet malfunction?

  - by eMgz

  Hi, Im trying to obfuscate a Java MIDlet with proguard. It runs ok on the PC, however, when I run it on the phone, the program opens, connects to the server, and then freezes. If I disable obfuscation, it runs ok again on the phone. Ive tryed all the obfuscation levels for apps (7, 8 and 9 at NetBeans), and none of them seems to work properly, and I cant release this app for comercial use without obfuscation. Also, the compiler throws some warnings: Note: duplicate definition of library class [java.io.ByteArrayOutputStream] Note: there were 14 duplicate class definitions. But I dont know if this is realy the problem. Does anyone knows what is wrong? The obfuscator arguments are listed below: Obfuscator Arguments (7): -dontusemixedcaseclassnames -default package '' -keep public class ** { public *; } Obfuscator Arguments (8): same as (7) plus -overloadaggressively. Obfuscator Arguments (9): same as (8) but -keep public class ** extends javax.microedition.midlet.MIDlet { public *; } instead. Thanks.

• Executing Secondary Applications

  - by JooBlow

  I have an application I am attempting to make "portable". The application contains a lot of secondary utility functions that I would like to execute on external files(from the app). I tried adding them in the build process but I didn't get any "Executables" for them(just the main one and a few others). Is there a way to get these to excute? They are basically command line utility functions to process some text files but use large files in the distribution and are also used by the main application. Thanks

• Routing classic asp and through an MVC application

  - by Matthias

  We are starting to convert a large classic asp application into MVC (using C#). An additional requirement is, that all classic routes get "translated" to MVC ones ('mydomain.com/productdetail.asp?id=13' should become 'mydomain.com/products/13') even before we start writing the first controller or view. So basically, we want to use the routing from MVC but have the classic asp handle the response. An these are my questions: How to use the new nice urls but have the classic asp handle the construction of the html result? Within the classic asp page, the new MVC url pattern should be used for links. What is the best way of translating the old urls to the new ones and make the accessible within the classic asp site (using COM I guess). When an old/classic url is requested, how would I correctly handle that request so that browsers/searchengines would understand that the page has moved to the new url? Thanks in advance!

• keep only GUI when converting vb6 app to c#?

  - by Craig Johnston

  I have a large VB6 app which I want to convert to C#. The majority of the code in VB6 is quite badly written. I thought that a good strategy would be to keep the GUI design since it is adequate and would be a pain to recreate. But I would want to rewrite the code behind the GUI and the data layer. I could keep the GUI design by using one of the VB6 to .NET converters provided by Microsoft. Would this be a good strategy?

• How to properly use CoreData validation & error framework ?

  - by Xav

  I've created a model in Xcode, and for various attributes I have minimum & maximum values defined and that are enforced by coreData at runtime. I'm using NSManagedObject validateValue:forKey:error to check for user input values. I was a bit disappointed to see that the localized error message is not specific, and I get a "The operation couldn't be completed. (Cocoa error 1620)" for too small values and a "The operation couldn't be completed. (Cocoa error 1610)" for too large values. It's written in the coreData documentation that "you can localize most aspects of a managed object model, including entity and property names and error messages". Unfortunately it's not very detailed on how you implement it for error messages. So How do you customize error message ? How do you localize them ? Is it possible to customize it in a way where it will mentioned the reference value ex: "Value should be lower than %@" or "Value should be higher than %@" ?

• Mixed alignment with Java Swing's GroupLayout

  - by zigdon

  I'm trying to build a GUI window in my application. What I'm trying to do is have a window, with a few buttons at the top, and a large text area. Something like this: +--------------------------------------------------+ | [button1] [button2] [button3] | | +----------------------------------------------+ | | | text area | | | | | | | | | | | | | | | +----------------------------------------------+ | +--------------------------------------------------+ I'm almost there, using GroupLayout: layout.setHorizontalGroup( layout.createParallelGroup() .addGroup(layout.createSequentialGroup() .addComponent(button1) .addComponent(button2)) .addComponent(closeWindow)) .addComponent(textarea1) ); layout.setVerticalGroup( layout.createSequentialGroup() .addGroup(layout.createParallelGroup() .addComponent(button1) .addComponent(button2) .addComponent(button3)) .addComponent(textarea) ); The problem is that this ends up with button3 aligned to the left, with the other two. I can't seem to figure out how I can specify the alignment on just that one button. I can do GroupLayout.Alignment.TRAILING on the entire button bar, but that hits all 3 buttons, which is also not quite right. So what's the correct approach? Since the alignment only applies for Parallel Groups, I don't think having a HorizontalGroup with two Sequential Groups in it will help? What am I missing?

• How do I manipulate the scroll bars so that a div with content that changes size is showing the same

  - by Shaun

  What I have is a div, for example is 800*800 px, and inside of this div is a SVG image, which can fit in the div but also can get very large, say 5000*5000 px, and I need to manipulate the scrollbars so that when the SVG has changed size the scrollbars adjust so that you are seeing the same center of your 'viewport' that you were seeing before. The reason I use 'viewport' is because I have seen exactly what I am trying to achieve done in WPF. Initially it sets the center as the center of the SVG so that when the SVG gets larger then the container the scrollbars automatically scroll to show the center of the SVG. If the user scrolls the 'viewports' center is updated and any changes in size now center there. I need this to be cross-browser compliant and done only with javascript. However I really don't care what container the SVG is being bounded by.

• What are the "cool" use cases for SharePoint?

  - by David

  I went to the Microsoft Visual Studio 2010 launch event in Minneapolis yesterday and was slightly surprised by how much they were trotting out SharePoint and improved SharePoint development in Visual Studio 2010. SharePoint is something I've largely ignored over the years as a web developer and solution architect on a small development team. I was always under the impression that SharePoint was used mostly for intranets in large corporations, and that if you were developing for SharePoint, it meant that a corporate decision had been made to use it and you as a developer probably had few (if any) options. I realize this assumption is probably incorrect. So, what are the "cool" uses for SharePoint? What unique business problems have you solved using it? What could make a developer excited to be working on something for SharePoint?
