• Animate a GIF using Core Animation layers?

  - by Cliff

  I'm trying to animate a GIF and I hit a roadblock. I have an example of what I'm trying to do that uses the individual frames of the GIF and setting the animationImages property of a UIView. However in my project, the thing I want to animate is drawn using Layers. I'm looking for a quick and easy way to animate the frames without introducing too much complexity. Is there any animationImages equivalent with Layers? Does anybody have any ideas?

  - by Jonathan Branthwaite

  Hi My portfolio site www.jonathanbranthwaite.co.uk uses heavy JQuery - sliding carousel and lightbox navigation. It works fine in Firefox and Safari, and from what I gather in IE 8. Does anyone know if the code is incorrect or if there is something making it crash, or is this just because of alot of JQuery. Any help would be appreciated. Thanks Jonathan

• How do I get rid of LD_LIBRARY_PATH at run-time?

  - by Kjir

  I am building a C++ application that uses Intel's IPP library. This library is installed by default in /opt and requires you to set LD_LIBRARY_PATH both for compiling and for running your software (if you choose the shared library linking, which I did). I already modified my configure.ac/Makefile.am so that I do not need to set that variable when compiling, but I still can't find the shared library at run-time; how do I do that? I'm compiling with the -Wl, -R/path/to/lib flag using g++

• ClickableSpan on TextView in App Widget

  - by Dave Allison

  I have created an App Widget for Android 1.5. It uses a TextView to present a number of individual Text Links using ClickableSpans. However, the onClick event handler on the ClickableSpan is never called, it appears that you can not select individual components on the widget just the whole widget. This approach works fine for a normal app, so what I do I need to change to make this work for a widget?

• writing large excel spreadsheets

  - by pstanton

  has anybody found a library that works well with large spreadsheets? I've tried apache's POI but it fails miserably working with large files - both reading and writing. It uses massive amounts of memory leaving you needing a supercomputer to parse or create a 20+mb spreadsheet. Surely there is a more memory efficient way and someone has written it?!

• Generate 2D cross-section polygon from 3D mesh

  - by nornagon

  I'm writing a game which uses 3D models to draw a scene (top-down orthographic projection), but a 2D physics engine to calculate response to collisions, etc. I have a few 3D assets for which I'd like to be able to automatically generate a hitbox by 'slicing' the 3D mesh with the X-Y plane and creating a polygon from the resultant edges. Google is failing me on this one (and not much helpful material on SO either). Suggestions?

• Can Grails output error messages in emacs format?

  - by ataylor

  Ant has a -e option for outputting error messages that can be parsed by emacs' compile command. For example, it is possible to do M-x compile, ant -e, then nagivate to any errors with C-x `. Is it possible to make grails output its compilation errors in this format? Alternatively, is there an emacs variable that can be customized to handle error messages in the format that grails uses?

• Why do some languages not use semicolons and braces?

  - by Incognito

  It is interesting that some languages do not use semicolons and braces, even though their predecessors had them. Personally, it makes me nervous to write code in Python because of this. Semicolons are also missing from Google's GO language, although the lexer uses a rule to insert semicolons automatically as it scans. Why do some languages not use semicolons and braces?

• Good reasons to pass paths as strings instead of using DirectoryInfo/FileInfo

  - by neodymium

  In my new code I am not using strings to pass directory paths or file names. Instead I am using DirectoryInfo and FileInfo as they seem to encapsulate a lot of information. I have seen a lot of code that uses strings to pass directory information then they "split" and "mid" and "instr" in long incomprehensible statements until they get the part of the directory they are looking for. Is there any good reason to pass paths as strings?

• Terminology for mobile computing with a tablet?

  - by Idrise_Coulombe

  This is more of a terminology question... I'm developing an occasionally connected application that will run on a tablet for clinicians or field service workers but I'm struggling with what this type of computing is referred to. Mobile computing as connotations of a phone app. Whereas our clients may be occasionally at their desk. Microsoft uses Smart Client a lot, but I'm not sure if that best describes this scenario or is the common term for this kind of computing.

• Any Open Source software using Orient DB database? Have you any experiences with that database?

  - by Juha Syrjälä

  Do you know any open source software that uses Orient DB? Or have you used that product yourself? Any experiences to share? I have recently looked into Orient DB, and it has nice and feature interesting feature set (fast, embeddable in Java, simple API) but it seems that it is not widely used. Is it just because the Orient DB is a new player on the field?

• Where can I find a good definition of a Software construct?

  - by Hugh

  I have scoured for 2 hours now across the internet, I have found courses with modules on software constructs but no clear definition only hints as to what one is. As far as I understand the definition it is an object that can be defined with a purpose for example a TCP/IP connection uses a Port which is a Software construct. Can anyone refer me to a full definition or give a more robust one?

• What is the best way to organize directories within a large grails application?

  - by egervari

  What is the best way to organize directories within a large grails application? In a typical Spring application, we'd have myproject/domain/ and myproject/web/controllers and myproject/services Since grails puts these artifacts in their own directories... and then just uses the same base project package for everything, what is the best practice? Use the same sub package name for domain objects, controllers, services too? Ken

• Practical examples of using symbols in Scala?

  - by Jesper

  Scala has symbols - names that start with a single quote ' and which are a kind of string constants. I know symbols from Ruby (where they start with a colon). In Ruby they are used for some meta-programming tasks, like generating getters and setters for member variables (for example attr_reader :name to generate a getter for name). I haven't seen a lot of use of symbols in Scala code yet. What are practical uses for symbols in Scala?

• iPhone PopUp RGB colors

  - by McLas

  Hi, I am presenting a UIView with an animation that takes half of the screen. I've seen it in many apps but could not find the appropriate RGB colors: iOS uses it for example in "contacts": http://img98.imageshack.us/img98/9402/image001u.png I'm trying with : bottomLayer.backgroundColor = [[UIColor colorWithRed:80.0/255.0 green:86.0/255.0 blue:97.0/255.0 alpha:1] CGColor]; but it's all whitey. If anyone could get how this popup is designed... Thanks!

  I read a book that uses infix, infixr, and infixl in the sample programs. I'm wondering what the differences are. I'm guessing that infixr performs operation from right to left, and vice versa.

• Pre-Compiled Header Design Question

  - by ML

  Hi All, I have code that uses a pre-compiled header. (previously done by someone else) In it, they are including several .h files. If I have classes that use common .h files that are not currently in the existing pre-compiled header, would tossing them in there be of any real benefit? Maybe compilation speed, but I was thinking it would clean up the classes/headers a bit too? What are do's and don't with pre-compiled headers?
