• Noob here, but wanting to try and make my own app.

  - by Justin

  Hi all, I have a small amount of programing experience with Siemens and Allen Bradley but would like to make my own app for a certain website I frequent. I would like the website to be a little more user friendly for me instead of having to open browser etc. Is it possible to have a simple forum translated into a widget so you can see the forum posts and post from there? The website in question is http://vnboards.ign.com Any ideas or suggestions no matter how bad are appreciated. If it isnt worth attempting or my skills may not be up to par, feel free to say so :P Dont pull any punches :) Thanks! Justin

• Java Sound Clip Looping Frame Position

  - by InsertNickHere

  Hi, I have a little problem with a loopting clip: If you have a soundfile e.g. 20000 samples long, the frame position will not reset after looping, so I get values that are "out of bounds" of the original soundfile. As I want to draw a position marker on my waveform, I'm a bit confused how to achive. At this time I just get myClip.getLongFramePosition() but this does not work as described above. Does anyone have an idea how to fix that? Is there a possibility to count how often a clip was looped before? Regards

• How does one write extconf.rb files when one extension includes header files from another?

  - by mohawkjohn

  This is a follow-up question for: Multiple Ruby modules under one directory What happens if these extensions include each other? For example, you have the following structure: ext/foo ext/bar In ext/bar/bar.h, you have a #include "foo.h" foo.h and foo.cpp compile to form foo.o, to make life a little more complicated. Finally, it is necessary that foo and bar be separate extensions. How is this managed? I can't figure out how to add ../foo to the search path for bar.h, primarily. Symbolic links seem hack-ish.

• Advice needed for a small web application's architecture/implementation

  - by Johhny P

  I was asked to build a website where a company's employees (around 20) could login and fill in their working schedules for a present and past (if needed) month. Employees should ofcourse only be able to see their own schedules, but the manager should have the privilege to access every schedule. I have little experience in web development therefore an advice is needed. I have already created a PHP/MySql login page. Now what? How do I go about it? Just some architectural or implementational(if you will) guidance would be really appreciated.

• Word on HTML document point.

  - by leolobato

  Hey guys, How can I figure out which word is at the point where the user tapped on a UIWebView? I am able to detect the CGPoint for the tap (subclassing UIWindow like this), and I can actually get the DOM element on that point using javascript. But I know very little of javascript and DOM to figure out how can I actually get which word the user tapped on. Is that possible? Here's what I have right now: int scrollPosition = [[webView stringByEvaluatingJavaScriptFromString:@"window.pageYOffset"] intValue]; NSString *js = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).tagName", point.x, point.y+scrollPosition]; NSString *value = [webView stringByEvaluatingJavaScriptFromString:js]; NSLog(@"element: %@", value);

• Why does this bash command take up all space on device?

  - by chelmertz

  Hey! I'm a little new on searching via bash, so feel free to give me suggestions on the methods to use instead of this, which I'll never use again :) I'm searching for occurances of a string, recursively in a directory, with ~50 not-that-large php-files in it; some in current directory, some in directories beneath current dir, three levels of directories down at most. The method I'm using is: find . | xargs grep "module" > module.txt When in simple (one level) directories, this works fine, but in this case, the file became 4 GB large until it filled up all space on the partition :) It wasn't even done yet.. Would someone educate me so I won't embarass myself again?

• Image size guidelines

  - by user502014

  Hi all, This may well be a little of an open-ended question The site I am working on requires to be optimised for performance. One of the key areas is to optimise the file sizes of the images used upon the site. Unfortunatley these images are being created by employees who do not have the required knowledge for creating images for the web, and it is my job to produce a set of guidelines for them to use. I was wondering whether there was any resource/guidlines/literature regarding typical images file sizes for images of different dimensions - as I would like to include something like this to aid them to ensure their images are being created properly. Any info would be greatly appreciated. Thanks in advance

• Passenger problem: "no such file to load" -- /config/environment

  - by Mason Jones

  I've been researching this one and found references to similar problems here and there, but none of them has led to a solution yet. I've installed passenger (2.2.11) and nginx (0.7.64) and when I start things up and hit a Rails URL, I get an error page informing me of a load error: no such file to load -- /path/to/app/config/environment From what I've found online this appears to be some sort of a user/permissions error, but I've tried all the logical fixes: I've made sure that /config/environment.rb is not owned by root, but by a webapp user. I've tried setting passenger_default_user, I've tried setting passenger_user_switching off. I've even tried setting the nginx user, though that shouldn't matter much. I've gotten some differing results, but nothing's actually worked. I'm hoping someone may have the magical combination of settings and permissions for this. I may try backing down to an earlier version of Passenger, because I've never had this issue before; it's been a little while since I set up Passenger though. Thanks for any suggestions.

• Know if a Visual Studio Website project is recompiling itself in the background?

  - by jdk

  A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

• Good File Organization Suggestions for Developer

  - by Paul

  I am struggling a little with folder organization to organize the many projects that I work on. I work on OS X - right now I am using ~/Development/ as the root folder, and I have many types of projects. For example, I have my iPhone apps under ~/Development/Xcode I develop in many languages, from PHP, to Ruby, to Python, to Objective-C. So, for example, I might have a couple of open-source apps based on PHP where I am using the Zend framework. Some of these projects are for clients, others are tests/experiments when learning a new language or general experimenting. I am really interested in how other developers have organized code/projects and could pass along some advice to make it very easy to navigate through code/projects related to many languages and types of projects.

• RegEx (or other) parsing of script

  - by jpmyob

  RegEx is powerful - it is tru but I have a little - query for you I want to parse out the FUNCTIONS from some old code in JS...however - I am RegEx handicapped (mentally deficient in grasping the subtleties).. the issue that makes me NOT EVEN TRY - is two fold - 1) myVar = function(x){ yadda yadda } AND function myVar(x) { yadda yadda } are found throuout - COLD I write a parser for each? sure - but that seems inefficient... 2) MANY things may reside INSIDE the {} including OTHER sets of {} or other Functions(){} block of text... HELP - does anyone have, or know of some code parsing snippets or examples that will parse out the info I want to collect? Thanks

• How do I extend the classpath used for 'grails run-app'

  - by Eric

  I have the following in my Config.groovy file: grails.config.locations = [ "classpath:env.groovy" ] Now, where exactly am I supposed to place "env.groovy" such that it is available on the CLASSPATH during grails run-app? The documentation here is sorely lacking. I am able to get it to work on the pure commandline by placing "env.groovy" in $APP_HOME/etc and then running: $ grails -classpath ./etc run-app This seems a little hackish, but I can live with it... However, I am unable to get any such configuration working when I launch run-app using the Grails eclipse plugin (STS): Unable to load specified config location classpath:env.groovy : class path resource [env.groovy] cannot be opened because it does not exist I've seen related posts here, here, here, and here but the answers have been unfulfilling. I am looking for a CLASSPATH-based solution that will work with 'run-app' in development mode (both commandline and from eclipse). I know how to set up the CLASSPATH for my deployment servlet container, so that is not an issue.

• Force Response to Download File(s) to Desktop with Ruby?

  - by viatropos

  I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and remote app resizes image image downloads automatically locally to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby. What's the basic concept behind this? What if I wanted to do this for multiple files? Åssuming I can get multiple files uploaded no problem, how can I download all of them automatically?

• BlackBerry. How to define direction of Scroll or Focus change?

  - by Lyubomyr Dutko

  Hi, does BlackBerry has any possibility to track focus or scroll change direction? I will describe a case. On UI we have a list and some horizontal tab bar (tab bar at top and below the list actually). If User is somewhere in the middle of a list and decides to click another tab, it appears a little difficult to put focus on the Tab control, so User scrolls to the first list item and after changes focus to tab (as a result very long operation). The point here How to catch event of horizontal scroll to change currently focused tab? And after if you scroll (by trackball) vertically you go back to list. Possibly you can advice with the right approach how to resolve such issues? Thanks Lyubomyr

• Using WCF to expose underlying process

  - by Steven

  I have a server application that spins up and monitors about 8 separate processes that gather data from different systems. The server app then runs some calculations over the aggregated data and stores it in a db. Simple stuff. I now have a requirement to modify the process so that it no longer saves data to the db but rather exposes it directly to clients via WCF. That's cool, I've used WCF a fair bit but I'm struggling a little with it for some reason. Basically my plan is to HOST the WCF service in my application and have calls redirect into the internals of my existing application but I can figure out how to do that without getting the WCF class to encapsulate the existing app. I want the service to inside my current app, not become it. Any suggestions?

• How to get selenium to click on an object other than by ID

  - by Zombies

  So here is a little challenge. I have an image. It has 2 attributes: a random ID - not helpful an image url - but it is a button, and other buttons use the same image url, not helpful a CSS class - also used by too many other things to be helpful a style - neither helpful nor unique This image is however inside of an anchor tag, but the anchor tab isn't to a page, it just runs some javascript. Bellow is the html in question: <a id="template:j_id__ctru168pc2" title="Click for the Manual Class LOV" class="xei" style="text-decoration: none;" onclick="return false;" href="#"> <img id="template:j_id__ctru169pc2" class="xgs" style="border: 0pt none;" src="images/lov_ena.png"> </a> How can I click this image without using the ID?

• Object pointer value as key into dictionary

  - by Ranking Stackingblocks

  I want to use the object's reference value as a key into a dictionary, as opposed to a copy of value of the object. So, I essentially want to store an object associated with a particular instance of another object in a dictionary and retrieve that value later. Is this possible? Is it completely against the idea of NSDictionary? I can tell that I am probably approaching this the wrong way because the dictionary wants me to implement NSCopying on the object itself, which doesn't really make sense in terms of what I'm doing. I can see that what I should really be doing is wrapping the pointer value, but that seems a little mad. Advice would be appreciated.

• R: how to make a unique set of names from a vector of strings?

  - by Mike Dewar

  Hi, I have a vector of strings. Check out my vector, it's awesome: > awesome [1] "a" "b" "c" "d" "d" "e" "f" "f" I'd like to make a new vector that is the same length as awesome but where, if necessary, the strings have been uniqueified. For example, a valid output of my desired function would be > awesome.uniqueified [1] "a" "b" "c" "d.1" "d.2" "e" "f.1" "f.2" Is there an easy, R-thonic and beautiful way to do this? I should say my list in real life (it's not called awesome) contains 25000ish mircoarray probeset identifiers. I'm always nervous when I embark on writing little generic functions (which I'm sure I could do) as I'm sure some R guru has come across this problem in the past, nailed it with some incredible algorithm that doesn't even have to store more than half an element in the vector. I'm just not sure what they might have called it. Probably not uniqueify.

• What is the state of model driven development in 2012?

  - by eriktheblond

  I haven't heard a lot of talk lately on model driven development, but some of my company's customers are using it. I know briefly what it is, but after trying to refresh my memory using Google I found that most of the information is from 2006-2007. Was it something that never really took off? More worryingly is the reason why the customers are asking: They want IEC 61508 complience. Is this actually a "not-so-good" idea that will live on simply because it is prescribed by a standard? I have too little experience to say if MDD is good idea or not (I'm guessing the right answer starts with "It depends"...), but the reasons for using it, that is standard complience, seems just wrong.

• C++ include header conventions

  - by user231536

  Suppose I have a file X.h which defines a class X, whose methods are implemented in X.cc. The file X.h includes a file Y.h because it needs Y to define class X. In X.cc, we can refer to Y because X.h has already included Y.h. Should I still include Y.h in X.cc ? I understand that I don't need to and I can depend on header guards to prevent multiple inclusions. But on the one hand, including Y.h makes X.cc a little more independent of X.h (can't be completely independent of course). What is the accepted practice? Another example: including <iostream> in both .h and .cc files. I see some people do this and some don't.

• Cascading Dropdown Listboxes with Selenium

  - by Jon

  I am having great difficultly testing cascading dropdown boxes with Selenium. I would like to know what the standard approach is for this. I'm a bit unclear as to which commands to use i.e. ClickAndWait, WaitForTextPresent etc. It seems a little bit of a hack to try and get this to work. Has anyone got selenium to correctly test this out? An example scenario would be to have 3 listboxes which have Car Make, Model and Colour. Each one is populated in turn by the other. Selenium needs to somehow wait for the next listbox to populate before preceeding with the test.

• Getting search results from Twitter in php

  - by Mark Mayo

  I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

• Get current session /process id from inside a mysql query

  - by Indra Ginanjar

  I'm trying to create a table for pseudo array variable. That looks like CREATE TABLE IF NOT EXISTS `MyArray`.`ArrayTable` ( `ID` INT UNSIGNED NOT NULL COMMENT 'Hash value of SessionID + ArrayName' , `SessionID` INT UNSIGNED NOT NULL , `ArrayName` CHAR(26) NOT NULL COMMENT '32 digit char - 6 digit longest process id (assumtion)' , `Index` INT UNSIGNED NOT NULL , `Value` TEXT NOT NULL , PRIMARY KEY (`ID`, `SessionID`) ) ENGINE = MyISAM; The table is not normalized yet, 'hope this will make it a little simpler to understand :) To avoid collission between client, there should be a differentiator between client session. For that reason i think need to know current session/process id (just like "SHOW PROCESSLIST") but really need to know IN WHICH process the query are?

• Opinions about Dabo

  - by driverate

  Has anyone used Dabo lately? How does it rate vs Boa Constructor, etc? I'm writing a new Python database app and Dabo looks promising, but what's the real-world scoop on it? Is it used by many developers? It's not talked about very much here on SO, or anywhere, as far as I can tell. I'm just a little concerned that the support community might be too small, or the possibility that writers might decide to throw in the towel. What is your assessment of Dabo?

• varchar data type to datetime data type resulted in an out-of-range??

  - by leen3o

  Very weird problem occurred, I have moved a site from one server to another - All is working, but any query involving a date is playing up. I get the following: DELETE FROM MYTABLE WHERE categoryId = -2 AND datecreated < '3/23/2010'; The conversion of a varchar data type to a datetime data type resulted in an out-of-range value Now what's strange is I have changed the LCID to 1033 on the new server as the date is showing as US format and its still throwing an error! I then tried 2057 and again the same error? Made no difference. I'm a little confused, as this is a working site from a server with IIS6 - The locale is 1033 on that server and it works perfectly!! :S I have just tried thrown a Cdate() around the date too and yet again the same error??? Any ideas??
