• Blackberry: Simulator stuck up launching through JDE 5.x

  - by user187532

  Hi, When i try to build my project in Blackberry JDE 5.0.0.25. It built successfully. And then when i click on Debug menu "Go" button, simulator is launching and stuck up lanching itself forever, does't come up the simulator screen normally and visible with apps showing. When i built the same project in Blackberry JDE 4.7, it built successfully and then click on "Go", launched the simulator normally and showed the app to play with it. Could someone guide me what should be problem? Do i need to set any settings specific to BB JDE 5.x? I have just the basic hello world empty screen in my project, so don't provide any code here. Thanks.

• Where is the default language data stored in OS 10.6

  - by George Baugh

  From a shell in 10.4 or 10.5, I was able to do this: /usr/bin/defaults read NSGlobalDomain AppleLanguages To get the list of the language preference for that particular machine. This was done so that I could restore it back to that list after changing it with the 'defaults write' command to something else (in order to help automate l10n testing). Now, along comes OS 10.6, and AppleLanguages is nowhere in any of our defaults domains. I know that I can alter it for each running application by altering their specific property lists...but at the cost of more complexity. Also, some of the apps I have under test here are installer packages...and It's a real pain to change stuff (like the .plist I'd have to change here) in those without being somewhat destructive; that's why I chose to do it globally in the first place. Anyways, it'd be great if I could find where they stashed it now...or if they deprecated it (like a zillion other things in OS 10.6) completely.

• Server-initiated Rendering: EJB -> FacesContext?

  - by egbokul

  I've already asked this question on the Icefaces forum, but meanwhile I realized that this is a more generic problem. I'd like to update parts of a JSF page when I get a message in my MDB. The problem is, how do I get the FacesContext from the EJB container? In the message processing function FacesContext.getCurrentInstance() returns null. I've also tried to make a JSF managed bean be a MDB, but I couldn't (it seems you can't have both in the same class?). Since I'm a beginner in the JSF world I'm kind of stuck now. Is there a way to make it work? (Glassfish v3 + Netbeans 6.8, JSF2 + Icefaces 2.0 alpha2)

• Domain-driven design with Zend

  - by mik

  This question is a continuation of my previous question here http://stackoverflow.com/questions/2122850/zend-models-architecture (big thanks to Bill Karwin). I've made some reading including this article http://weierophinney.net/matthew/archives/202-Model-Infrastructure.html and this question http://stackoverflow.com/questions/373054/how-to-properly-create-domain-using-zend-framework Now I understand, what domain driven design is. But examples are still very simple and poor. They are based on one table and one model. Now, my question is: do they use Domain Model Design in real-world PHP projects? I've been looking for some good documentation about this, but I haven't found anything good enough, that explains how to manage several tables and transfer them to Domain Objects. As long as I know, there is Hibernate library, that has this features in Java, but what should I use in PHP (Zend Framework)?

• Programmatically determine DPI via the browser?

  - by Brandon Pelfrey

  Hi all. I would like to programmaticaly determine the DPI of a user's display in order to show a web page at a precise number of units (centimeters/inches). I know it a weird request: it's for a visualization research project and it's kind of a control. We currently do it by having the user place a credit card to the screen and match a resizable div (via Mootools) to the real credit card, and voila we can get the DPI and display the page correctly. Can anyone think of a programmatic way to do this?

• How can I check the version of an assembly then delete the assembly?

  - by Nescio

  I am using the FileVersionInfo to retrieve the version of a .Net assembly. Then, I want to immediately delete the file. Unfortunately after I call GetVersionInfo, any attempt to delete the file results in an error “…in use by another process…” Is there another technique to determine the version that does not lock the file? Or, is it possible to ensure the lock is released after calling GetVersionInfo? The below example is heavily simplified, but scope matches my real code. void Main() { var fvi = GetVersion("myPath"); if (fvi.ToString() == "2.0.0.7") DeleteFile("myPath"); } FileVersionInfo GetVersion(string path) { return FileVersionInfo.GetVersionInfo(path); } void DeleteFile(string path) { File.Delete(path); }

• CODE1 at SPOJ - cannot solve it

  - by VaioIsBorn

  I am trying to solve the problem Secret Code on SPOJ, and it's obviously a math problem. The full problem For those who are lazy to go and read, it's like this: a0, a1, a2, ..., an - sequence of N numbers B - a Complex Number (has both real and imaginary components) X = a0 + a1*B + a2*(B^2) + a3*(B^3) + ... + an*(B^n) So if you are given B and X, you should find a0, a1, ..an. I don't know how or where to start, because not even N is known, just X and B. The problem is not as easy as expressing a number in a base B, because B is a complex number. How can it be solved?

• From interpeted to native code: "dynamic" languages compiler support

  - by Daniel

  First, I am aware that dynamic languages is a term used mainly by a vendor; I am using it just to have a container word to include languages like Perl (a favorite of mine), Python, Tcl, Ruby, PHP and so on. They are interpreted but I am interested here to refer to languages featuring strong capability to support the programmer efficiency and the support for typical constructs of modern interpreted languages My question is: there are dynamic languages can be compiled efficiently in native executable code - typically for Windows platforms? Which ones? Maybe using some third part ad-hoc tools? I am not talking about huge executables carrying with them a full interpreter or some similar tricks nor some smart module able to include its own dependances or some required modules, but a honest, straight, standard, solid executable code. If not, there is some technical reason inhibiting the availability of such a best-of-both-world feature? Thanks! Daniel

• C# Button Text Unicode characters.

  - by Fossaw

  C# doesn't want to put Unicode characters on buttons. If I put \u2129 in the Text attribute of the button, the button displays the \u2129, not the Unicode character, (example - I chose 2129 because I could see it in the font currently active on the machine). I saw this question before, link text, but the question isn't really answered, just got around. I am working on applications which are going all over the world, and don't want to install all the fonts, more then "don't want", there are that many that I doubt the machine I am working on has sufficient disk space. Our overseas sales agents supply the Unicode character "numbers". Is there another way forward with this? As an aside, (curiosity), why does it not work?

• Perl: parsing string enclosed by double quotes

  - by sfactor

  I need to parse tab/space delimited files that have a lot of columns in Perl. The values are such that the there are large strings enclosed within double quotes. These strings can have any characters such as tabs and spaces or anything else. When I try to parse them with the split function it splits these strings as well. Now how can I make perl understand that the strings within the " " are a single column entry? A simple example is, 12 345546.67677 "Hello World!!!" -567.55656 0.5465767 "Hello_Again; "

• Qt4 book says "make release", reality disagrees

  - by DarenW

  Writing some simple Qt4 demos depending the book by Daniel Molkentin. In that book, it says you build the release or debug versions of your app with "make release" or "make debug". In real life, these give errors. Only bare naked "make" works. I assume something has changed between the version of Qt4 used in the book and the version I'm using, qt4.6.2. So what is the proper way to determine whether to make release or debug? (And why can't google find any updates or errata for this book relating to this?)

• cc1plus: error: include: Value too large for defined data type when compiling with g++

  - by Android

  I am making a project that should compile on Windows and Linux. I have made the project in Visual Studio and then made a makefile for linux. I created all the files in Windows with VS. It compiles and runs perfectly in VS but when I run the makefile and it runs g++ I get $ g++ -c -I include -o obj/Linux_x86/Server.obj src/Server.cpp cc1plus: error: include: Value too large for defined data type cc1plus: error: src/Server.cpp: Value too large for defined data type The code is nothing more than a Hello World atm. I just wanted to make sure that everything was working before I started development. I have tried searching but to no avail. Any help would be appreciated.

• MATLAB is changing variables when I do not want it to.

  - by WVUstudent

  Here is my problem in a small bit of code used as an example, trial(0) function [] = trial(test) disp(test) if(test == 1) disp('test is one') test = 0; end disp(test) Matlab prints out this: 0 'test is one' 0 This is not my real code, there are over 500 lines of it, but this is a section of my code where the problem has risen. I have used the search function to see if I have been incrementing any variables anywhere, and have put in over 2 hours trying to see why MATLAB is changing my variables when I don't want it to.

• Another Java vs. Scala perspective - is this typical?

  - by Alex R

  I have been reading about Scala for a while and even wrote some small programs to better understand some of the more exoteric features. Today I decided to do my first "real project", translating some 60 lines of ugly Java code to Scala to rewrite it using the better pattern-matching features (why? because the Java version was becoming hard to maintain due to excessive combination of regex and conditionals). About halfway through the editing process, Eclipse thew up this error: I get the general impression that the Scala IDE in Eclipse is a lot buggier and less complete than its Java equivalent. Is this correct or do I just have a bad installation? Is there a better IDE for Scala?

• C# LINQ Where Predicate Type Arguments

  - by blu

  I have an XElement with values for mock data. I have an expression to query the xml: Expression<Func<XElement, bool>> simpleXmlFunction = b => int.Parse(b.Element("FooId").Value) == 12; used in: var simpleXml = xml.Elements("Foo").Where(simpleXmlFunction).First(); The design time error is: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly' The delegate supplied to Where should take in an XElement and return a bool, marking if the item matches the query, I am not sure how to add anything more to the delegate or the where clause to mark the type. Also, the parallel method for the real function against the Entity Framework does not have this issue. What is not correct with the LINQ-to-XML version?

• Grails application hogging too much memory

  - by RN

  Tomcat 5.5.x and 6.0.x Grails 1.6.x Java 1.6.x OS CentOS 5.x (64bit) VPS Server with memory as 384M export JAVA_OPTS='-Xms128M -Xmx512M -XX:MaxPermSize=1024m' I have created a blank Grails application i.e simply by giving the command grails create-app and then WARed it I am running Tomcat on a VPS Server When I simply start the Tomcat server, with no apps deployed, the free memory is about 236M and used memory is about 156M When I deploy my "blank" application, the memory consumption spikes to 360M and finally the Tomcat instance is killed as soon as it takes up all free memory As you have seen, my app is as light as it can be. Not sure why the memory consumption is as high it is. I am actually troubleshooting a real application, but have narrowed down to this scenario which is easier to share and explain.

• Scrum burn down charts, can they go negative?

  - by AaronThomson

  I work on a small Agile development team which is part of a large, non-agile thinking corporation. Currently, we practise Scrum and occasionally, we exceed our sprint commitment. My question is, how do you handle burn down charts when you have exceeded your sprint commitment? I can think of two options: Extend the y-axis in the negative direction and keep counting down Add more cards/stories/work and have the burn down value increase by that amount, burning down when that work is finished. The ultimate solution for my team is one which is clear to the business and adds real value for the developers. So far, neither of these solutions has worked out perfectly.

• Android multiple screen sizes and density problems

  - by Ben Mc

  I'm having a real problem with my drawables that I just can't seem to figure out. The problem is this: There are screen sizes at approximately 320x480, 480x800, 480x854 Then there are most commonly densities at 1.0 (160) and 1.5 (240) Now, on a Droid, the screen size is 480x800 and the density is reporting using DisplayMetrics as 1.5 On the G1, it's 320x480 and reporting back at a density of 1.0 BUT tablet devices are reporting back at 480x800 with a density of 1.0 (160) So, I'm going mad because I can put 320x480 images in the drawables-mdpi folder and 480x800 images in the drawables-hdpi folder, but on Tablet computers, no matter what it's not resizing up anything to a full screen. Any help would be greatly appreciated. I just want all of my 320x480 images to scale up regardless of the device.

• java.util.BitSet -- set() doesn't work as expected

  - by dwhsix

  Am I missing something painfully obvious? Or does just nobody in the world actually use java.util.BitSet? The following test fails: @Test public void testBitSet() throws Exception { BitSet b = new BitSet(); b.set(0, true); b.set(1, false); assertEquals(2, b.length()); } It's really unclear to me why I don't end up with a BitSet of length 2 and the value 10. I peeked at the source for java.util.BitSet, and on casual inspection it seems to fail to make sufficient distinction between a bit that's been set false and a bit that has never been set to any value... (Note that explicitly setting the size of the BitSet in the constructor has no effect, e.g.: BitSet b = new BitSet(2);

• Jquery find next/prev elements of a certain class but not necessarily siblings

  - by Gnuffo1

  The next, prev, nextAll and prevAll methods are very useful, but not if the elements you are trying to find are not in the same parent element. What I want to do is something like this: <div><span id="click">hello</span></div> <div><p class="find">world></p></div> When the span with the id "click" is pressed, I want to match the next element with the class "find", which in this case is not a sibling of the clicked element so next or nextAll won't work.

• How do I maintain scroll position in MVC?

  - by Eric Brown

  Im working on a project in MVC and have enjoyed learning about it. There are a few growing pains but once you figure them out it's not bad. One thing that is really simple in the WebForms world is maintaining the scroll position on a page. All you do is set the MaintainScrollPositionOnPostback property to true. However, in MVC, Im not using postbacks so this will not work for me. What is the standard way of handling this? Edit: Ajax is acceptable, but I was also wondering how you would do it without AJAX.

• Permission denied - /tmp/.ruby_inline/Inline_ImageScience_cdab.c

  - by Ikaros

  I have a Ruby on Rails app that I've recently deployed to a remote server (Ubuntu 9.10, nginx, passenger, ruby-enterprise) and I'm getting the error (works fine locally): Permission denied - /var/www/project_name/tmp/.ruby_inline/Inline_ImageScience_cdab.c First, the folder /tmp/.ruby_inline/ is empty - should it be? Is it trying to create Inline_ImageScience_cdab.c or read it? I think I have all the required gems installed: 'gem list' shows image_science and RubyInline installed. libfreeimage3 and libfreeimage-dev are also installed. I've run chmod 755 on /tmp/.ruby_inline/ to match the permissions on surrounding folders but I cannot go any higher than that, however, or I get another error: /var/www/project_name/tmp/.ruby_inline is insecure (40777). It may not be group or world writable. Exiting. And I guess second, why am I getting this error? :) Thanks

• get height on a block of latex output

  - by georg raba

  Hello, I am trying to determine how to get the height on a block of latex output (not the whole document, and not the code..but rather a block of output). As an example of what I am trying to accomplish: i were to have the latex code $\sum_{i=0}^\infty \frac{1}{n}\infty$ \newline hello world \newline hello universe its output would be something like 2 inches high. Of course, the height of the above block of text is dependent on a number of things-font, margin size, etc, as changing any of these parameters changes how many inches that output would be. Is there a command/package that does this? Thanks in advance! Georg Raba

• Is a successor for TeX/LaTeX in sight?

  - by Mnementh

  TeX/LaTeX is great, I use it in many ways. Some of it's advantages are: it uses text files, this way the input-files can be diffed and many tools exist to work with text it is very flexible it has a stable layout: if I change something at the start of the document, it doesn't affect other things at the end of the document it has many extensions to reach different goals (a successor would start without extensions, but would have a good extension-system) you can use standard build control tools to support complicated documents (thanks dmckee) you can encapsulate solutions and copy&paste them to new documents or send them to others to learn from (thanks dmckee) But on the other hand some little things are not so good: it is hard to learn at the beginning it is complicated to control position of images a few things are a little counter-intuitive sometimes you have to type too much (begin{itemize} ... \end{itemize}) So, does there exist a successor/alternative to LaTeX or at least is some hot candidate for an alternative in development. A real successor/good alternative would keep the advantages and fix the disadvantages, or at least some of them.
