• What are you using for Web UI/layout design?

  - by brendan

  What are folks out there using for web/ui design? For the most part we use PowerPoint at my company. The UI folks will mock up a screen in PowerPoint and we (the development group) will take it from there. So, for a side gig of mine I decided to do some mock ups to show the client prior to dev and I'm quickly feeling that PowerPoint is not the right tool for this. What are you using for this type of stuff - some other software? pen/paper?

• inspect the parameters to "use", and pass on the rest?

  - by JoelFan

  I have a Perl module and I'd like to be able to pick out the parameters that my my module's user passed in the "use" call. Whichever ones I don't recognize I'd like to pass on. I tried to do this by overriding the "import" method but I'm not having much luck. EDIT: To clarify, as it is, I can use my module like this: use MyModule qw/foo bar/; which will import the foo and bar methods of MyModule. But I want to be able to say: use MyModule qw/foo doSpecialStuff bar/; and look for doSpecialStuff to check if I need to do some special stuff at the beginning of the program, then pass qw/foo bar/ to the Exporter's import

• Emacs with CEDET changes copy/paste to include trailing spaces?

  - by Paul D.

  I just started trying out CEDET today, which I really like, but it seems to do something completely worthless with respect to copying/pasting. If I highlight some stuff and copy it, when it gets pasted back the newlines are eliminated and there is just a ton of trailing whitespace on each line. This is really worthless. All I have in my .emacs right now for CEDET is the following: (load-file "~/.emacs.d/cedet-1.0pre7/common/cedet.el") (require 'semantic-ia) (require 'semantic-gcc) (semantic-load-enable-code-helpers) Does anybody know how to turn this off? I can't find anything about this except that the CEDET main page says it has "magic copy & paste".

• SWIG-Lua question on class returning another class

  - by John Smith

  I am concreting a question I had earlier. I have two classes in C++ and I use SWIG to wrap them. A method in one class can return a pointer to the other class. How can I get Lua to see it as more than just a userdata? More concretely: I have class fruit { int numberofseeds; //some other stuff about fruit constructors etc... public: getseedcount() { return numberofseeds; } } class tree { fruit * apple; public: //constructors and whatnot fruit * getfruit() { return apple; } } I wrap these two class with SWIG so I can access them in Lua So I can get in Lua the object x=pomona.tree(grannysmith). My question now is: How can I arrange for things so that when I type y=x:getfruit() I will get a pomona:fruit type object? Where I can write something line y:getseedcount()? At the moment all I get is userdata which not edible.

• Prims vs Polys: what are the pros and cons of each?

  - by Richard Inglis

  I've noticed that most 3d gaming/rendering environments represent solids as a mesh of (usually triangular) 3d polygons. However some examples, such as Second Life, or PovRay use solids built from a set of 3d primitives (cube, sphere, cone, torus etc) on which various operations can be performed to create more complex shapes. So my question is: why choose one method over the other for representing 3d data? I can see there might be benefits for complex ray-tracing operations to be able to describe a surface as a single mathematical function (like PovRay does), but SL surely isn't attempting anything so ambitious with their rendering engine. Equally, I can imagine it might be more bandwidth-efficient to serve descriptions of generalised solids instead of arbitrary meshes, but is it really worth the downside that SL suffers from (ie modelling stuff is really hard, and usually the results are ugly) - was this just a bad decision made early in SL's development that they're now stuck with? Or is it an artefact of what's easiest to implement in OpenGL?

• UITableViewCell and strange behaviour in grouped UITableView

  - by evangelion2100

  I'm working on a grouped UITableView, with 4 sections with one row per section, and have a strange behaviour with the cells. The cells are plain UITableViewCells, but the height of the cells are around 60 - 80 pixel. Now the tableview renders the cells correct with round corners, but when I select the cells, they appear blue and recangle. I don't know why the cells behave like this, because I have another grouped UITableView with custom cells and 88 pixel height and those cells work like they should. If I change the height to the default height of 44 pixel, the cells behave like the should. Does anyone know about this behaviour and what the cause is? Like I mentioned, I don't do any fancy stuff I use default UITableViewCells in a static, grouped UITableView with 4 sections with 1 row in each section. evangelion2100

• Receiving SQL Server events from a CLR function

  - by Pablo Lerner

  I wrote a CLR class with several methods, which are linked as functions in a SQL Server 2005 database. When several of these functions are used in scope of one transaction or connection, I need another one to be automatically executed to clean up some stuff, at the time of transaction or connection close (either time is good for now, later I will decide which is best). I figure that receiving events from another new CLR functions can do, but I don't know how to achieve that. Can anyone point me to information on modules, documents or whatever, that can help me understand how to receive transaction or connection closing events in a CLR class, or how to execute a particular function when these events occur?

• [SOLVED]Port C's fread(&struct,....) to Python

  - by user287669

  Hey, I'm really struggling with this one. I'am trying to port a small piece of someone else's code to Python and this is what I have: typedef struct { uint8_t Y[LUMA_HEIGHT][LUMA_WIDTH]; uint8_t Cb[CHROMA_HEIGHT][CHROMA_WIDTH]; uint8_t Cr[CHROMA_HEIGHT][CHROMA_WIDTH]; } __attribute__((__packed__)) frame_t; frame_t frame; while (! feof(stdin)) { fread(&frame, 1, sizeof(frame), stdin); // DO SOME STUFF } Later I need to access the data like so: frame.Y[x][y] So I made a Class 'frame' in Python and inserted the corresponding variables(frame.Y, frame.Cb, frame.Cr). I have tried to sequentially map the data from Y[0][0] to Cr[MAX][MAX], even printed out the C struct in action but didn't manage to wrap my head around the method used to put the data in there. I've been struggling overnight with this and have to get back to the army tonight, so any immediate help is very welcome and appreciated. Thanks

• Finding the attributes on the properties of an instance of a class

  - by Dan

  Given an instance of a class I want to set properties on attributes at runtime. So I tried this, but as far as I can tell this finds the attributes on the class not the instance, so any changes I make to the attribute properties have no effect. var properties = myObject.GetType().GetProperties(); foreach (object prop in properties) { var attribute =prop.GetCustomAttributes(typeof(MyAttribute), true)[0]; //attribute.MyProp do some stuff } If I try using type descriptor like below, there is no way of getting to the attributes on the properties. var myObject= (MyClass) object; PropertyDescriptorCollection props = TypeDescriptor.GetProperties(myObject); //There is no props[0].GetCustomAttributes(

• analyzing hashes

  - by calccrypto

  Is anyone willing to devote some time to helping me analyze a (hopefully cryptographically secure) hash? I honestly have no idea what im doing, so i need someone to show me how to, to teach me. almost all of the stuff ive found online have been really long, tedious, and vague the code is in python because for some reason i dont know c/c++. all i know about the hash: 1. there are no collisions (so far) and 2. differences between two similar inputs results in wildly different differences and please dont tell me that if i dont know what im doing, i shouldnt be doing it.

• Is there any "modern" text editor with command-line?

  - by Pedro Morte Rolo

  A command line in a text editor is a wonderful feature. It allows the user to explore the editor's functionality and learn it's shortcuts in a textual way. It's much faster than using the mouse, and it is much easier to memorise "shortcuts" this way. Emacs and VI provide this, though, emacs and vi are not "modern". By "modern", I mean one that is original built to cope with the modern de-facto standards of selecting, copying, pasting, cutting, undoing, redoing and auto-completing. Cream/vi or EmacsCUE are not valid options, since there are loads of things built over them that conflict with the mentioned stuff. Is there any alternative? (I do not intend to use the "modern" term as derrogatory. I love both Emacs and VI, but I hate their keyboard shortcut baggage.) (please do not advertise Vim and Emacs, that's not answering the question. I am asking for alternatives)

• MySQL Query involving column names containing math operators

  - by devil_fingers

  I'm a MySQL scrub, and I have asked around and checked around the internet for what I'm sure will turn out to be something obvious, but I'm very frustrated with what I thought would be a very, very simple query not working. So here goes. Please be gentle. Basically, in a large database, some of the column names contain mathematical operators like "/" and "+." (Don't ask, it's not my database, I can't do anything about it). Here is the "essence" of my query (I took out the irrelevant stuff for the sake of this question): SELECT PlayerId, Season, WPA/LI AS WPALI FROM tht.stats_batting_master WHERE Season = "2010" AND teamid > 0 AND PA >= 502 GROUP BY playerid ORDER BY WPALI DESC When I run this, it returns "Unknown column 'LI' in 'field list'," I assume because it sees the "/" in WPA/LI as a division sign. Like I said, I'm sure this is easy enough to work around (it must be given how much this database is used), but I haven't' been able to figure out how. Thanks in advance for any help.

• ShGetFileInfo called for directory oddity

  - by Axarydax

  Hello, I have a simple file browser and there I display files and folders, obtained by (for directory) SHFILEINFO info = new SHFILEINFO(); SHGetFileInfo(filename, FILE_ATTRIBUTE_DIRECTORY, ref info,Marshal.SizeOf(info), SHGFI_ICON | SHGFI_USEFILEATTRIBUTES | SHGFI_SMALLICON | SHGFI_ADDOVERLAYS); It works 100% fine, but I have noticed an oddity - if I try to obtain an icon for directory, but specify FILE_ATTRIBUTE_NORMAL instead of FILE_ATTRIBUTE_DIRECTORY but it does weird stuff for directories - normal folders have "unknown file type white paper" icons, recycle bin has VLC icon, etc. Directories under SVN have proper overlay, but base file icon (white sheet of paper). I understand that base icon for directory would now be the one of unknown file, but why do some folders have totally strange icon? Config.MSI has installer icon, recycle bin has VLC icon (wtf?!), etc. What does the shell function do with this parameters? Exactly what icon does it obtain? Again, this is not a problem, I'm just curious.

• How to implement "drag n drop" user interface on website?

  - by Nikkeloodeni

  Hello, I was wondering what would be the best way to implement some kind of "drag n drop" user interface? What i mean is that there would be one main page and every link click (eg. other sections like about, gallery, contact form) would open a new drag n drop element on top of that main page. Something like windows desktop where you can move your application windows around the screen. Would it be best to call different functions with AJAX when a link is clicked? Like "gallery" link would call gallery-function and retrieve dynamically generated contents of that "window" with AJAX call and then just load that stuff on some div? Or would some other type of approach suit better for this? I hope I was able to explain this clearly enough. I'm looking for a proper "design pattern" to implement this. All suggestions are wellcome! :)

• Template meta-programming with member function pointers?

  - by wheaties

  Is it possible to use member function pointers with template meta-programming? Such as: class Connection{ public: string getName() const; string getAlias() const; //more stuff }; typedef string (Connection::*Con_Func)() const; template<Con_Func _Name> class Foo{ Connection m_Connect; public: void Foo(){ cout << m_Connect.(*_Name); } }; typedef Foo<&Connection::getName> NamedFoo; typedef Foo<&Connection::getAlias> AliasFoo; Granted, this is rather contrived but is it possible? (yes, there are probably much better ways but humor me.)

• Should I make my MutexLock volatile?

  - by sje397

  I have some code in a function that goes something like this: void foo() { { // scope the locker MutexLocker locker(&mutex); // do some stuff.. } bar(); } The function call bar() also locks the mutex. I am having an issue whereby the program crashes (for someone else, who has not as yet provided a stack trace or more details) unless the mutex lock inside bar is disabled. Is it possible that some optimization is messing around with the way I have scoped the locker instance, and if so, would making it volatile fix it? Is that a bad idea? Thanks.

• listView.setAdapter doesn't work

  - by Bowiz2

  I have a listview called quotesList, and I am trying to use an adapter to put information in it. Here is my code: ListView listView = (ListView) findViewById(R.id.quotesList); String[]values={"Android","iOS","Windows Phone","Other Stuff"}; ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, android.R.id.text1,values); listView.setAdapter(adapter); The only error that Eclipse shows is in the listView.setAdapter(adapter) line. The bold represents where the red squiggly is. Syntax error on token "adapter", VariableDeclaratorId expected after this token The period after listView gives an error as well, but I'm pretty sure its just related to the other error, as its a syntax error. Syntax error on token(s), misplaced construct(s) Thanks in advance!

• Is this a correct iText design?

  - by Lucas

  I´m making some pdf reports to be used on a web app. I wonder if the way I´m taking to make the designs is appropriated. This would be a screenshot of the way I´m doing the things. As you can see, I´m using tables to position everything in the document. I think this is a pretty much similar design to HTML. But I want to know is there is a better way to get the same result I got. This is the document without cell borders: I could post the code if necessary. By the way, why should I spend long hours programming these kind of stuff with iText tool when I could do things faster and maybe better looking with iReport? I like iText, it´s just a question. Sorry for my english and thanks!

• Best and safest Java Profiler for production use?

  - by Pete

  I'm looking for a Java Profiler for use in a very high demand production environment, either commercial or free, that meets all of the following requirements: Lightweight integration with code (no recompile with special options, no code hooks, etc). Dropping some profiler specific .jars alongside the application code is ok. Should be able to connect/disconnect to the JVM without restarting the application. When profiling is not active, no impact to performance When profiling is active, negligible impact to performance. Very slight degradation is acceptable. Must do all the 'expected' stuff a profiler does - time spent in each method to find hotspots, object allocation/memory profiling, etc. Essentially I need something that can sit dormant in production when everything is fine without anyone knowing or caring that it is there, but then be able to connect to it hassle (and performance degradation) free to pinpoint the hard to find problems like hotspots and synchronization issues.

• Asking for input without stopping the script in python.

  - by ImTooStupidForThis

  I am (trying) to make a simple IRC client in python (as kind of a project while I learn the language). I have a loop that I use to receive and parse what the IRC server sends me, but if I use raw_input to input stuff, it stops the loop dead in its tracks until I input something (obviously). How can I input something without the loop stopping? Thanks in advance. (I don´t think I need to post the code, I just want to input something without the while 1 loop stopping.)

• Cannot customize Solution Explorer project context menu in VS 2010

  - by mikoro

  I'm trying to customize that context menu which comes up when you right click the project in the Solution Explorer. When I goto: Tools - Customize - Commands - Context Menu (radio button) - Project and Solution Context Menus | Project (drop down) I get nothing in the "controls:" list. I can modify other context menus starting with "Project and Solution Context Menus" but none of them is the right one. Any ideas? Currently I have ReSharper, PowerTools and StyleCop installed, but I have installed and uninstalled bunch of other addins (dotTrace, CodeIt.Right, VisualHG, DevExpress, random stuff from Extension Manager).

• MooTools Problem in IE with Request

  - by trobrock

  I have this class method in a mootools class: getData : function(){ var r = new Request.JSON({ url : this.container.getAttribute('data-url'), method : 'post', onSuccess : function(j){ this.cards = j; this.prepareQuiz(); }.bind(this) }).send(); }, In any browser aside from IE this works fine, but in IE I get a this.cards is not defined in a method that occurs after the this.prepareQuiz method does it's stuff. I narrowed the problem to this section by adding an if ($defined(this.cards)) before the this.prepareQuiz call and if I just keep refreshing the page 1 out of every 5 or so times it will work. So the this.cards variable is not being set some of the time for some reason. Why would this happen?

• Get controller method caller (3rd party webservice)

  - by bastijn

  Is it possible to retrieve the URL of a 3rd party webservice calling my controller method? Things like Request.Current.Url refer to my own URL (/someController/someAction/). The 3rd party webservice is sending HTTP POST data to my /someController/someAction and I wish to send back a HTTP POST message to the caller of the method, the 3rd party webservice, without using return Content["some response"] which will force me to exit the method. Since the answer is plain text I would like to send it using HTTP Post. What I actually try to do is respond to the calling webservice without exiting my method (return Content() will exit) so I can call other methods to process the data send to me by the webservice. I want to first tell the webservice I received their stuff and than process, in this way when a processing error occurs the webservice at least will not resend old data. Is there another way to do this than building your own HTTP post?

• Is it possible to optimize maven dependencies automatically?

  - by AlexR

  I am working on a big project that consists of about 40 sub-projects with very not optimized dependencies. There are declared dependencies that are not in use as well as used but undeclared dependencies. The second case is possible when dependency is added via other dependency. I want to remove redundant and add required dependencies. I ran mvn dependency:analyze and got a long list of warnings I have to fix now. I wonder whether there is maven plugin or any other utility that can update my pom.xml files automatically. I tried to do it manually but it takes a lot of time. It seems it will take a couple of days of copy/paste to complete the task. In worse case I can write such script myself but probably ready stuff exists? Here is how mvn dependency:analyze reports dependency warnings: [WARNING] Used undeclared dependencies found: [WARNING] org.apache.httpcomponents:httpcore:jar:4.1:compile [WARNING] Unused declared dependencies found: [WARNING] commons-lang:commons-lang:jar:2.4:compile [WARNING] org.json:json:jar:20090211:compile
