• How do I manage multiple development branches in GIT?

  - by Ian

  I have 5 branches of one system - lets call them master, London, Birmingham, Manchester and demo. These differ in only a configuration file and each has its own set of graphics files. When I do some development, I create a temp branch from master, called after the feature, and work on that. When ready to merge I checkout master, and git merge feature to bring in my work. That appears to work just fine. Now I need to get my changes into the other Branches, without losing the differences between then that are there already. How can I do that? I have been having no end of problems with Birmingham geting London's graphics, and with conflicts within the configuration file. When the branch is finally correct, I push it up to a depot, and pull each Branch down to a linux box for final testing, From there the release into production is using rsync (set to ignore the .git repository itself). This phase works just fine also. I am the only developer at the moment, but I need to get the process solid before inviting assistance :)

• Rate my C# code (~300 SLOC) using GDI+/Backgroundworker

  - by sebastianlarsson

  Hi, I want to get some feedback on my code! Below is some background info. I am taking a pre-certification course in C# (Sweden, 15 ECTS). The focus of the course is theoretical and only limited practical work. I dont find the assignments very hard at all to tell you the truth, but since I only have very limited work experience as a developer (I have worked 15h/week at Ericsson since November) I think I would benefit from having the certificate (70-536 and more probably). I am currently reading Martin Fowler's "Refactoring: Improving the design of existing code" and I tried to apply his techniques to my latest lab in the course. I have been on the lookout for a website which have the idea of providing feedback on code, but so far I have yet to discover any. Please take a look on my code and tell me what you think. It is only roughly 300 lines of code divided into a couple of classes. GDI+, backgroundworker and user controls are what the lab is about. I reckon you may have to spend as little as a couple of minutes on looking on the solution. Link to solution: http://www.filefactory.com/file/b18h7d5/n/Lab4_Lab5_SebastianLarsson.zip Regards and thank you, Sebastian

• Google calendar query returns at most 25 entries

  - by Dean Hill

  I'm trying to delete all calendar entries from today forward. I run a query then call getEntries() on the query result. getEntries() always returns 25 entries (or less if there are fewer than 25 entries on the calendar). Why aren't all the entries returned? I'm expecting about 80 entries. As a test, I tried running the query, deleting the 25 entries returned, running the query again, deleting again, etc. This works, but there must be a better way. Below is the Java code that only runs the query once. CalendarQuery myQuery = new CalendarQuery(feedUrl); DateFormat dfGoogle = new SimpleDateFormat("yyyy-MM-dd'T00:00:00'"); Date dt = Calendar.getInstance().getTime(); myQuery.setMinimumStartTime(DateTime.parseDateTime(dfGoogle.format(dt))); // Make the end time far into the future so we delete everything myQuery.setMaximumStartTime(DateTime.parseDateTime("2099-12-31T23:59:59")); // Execute the query and get the response CalendarEventFeed resultFeed = service.query(myQuery, CalendarEventFeed.class); // !!! This returns 25 (or less if there are fewer than 25 entries on the calendar) !!! int test = resultFeed.getEntries().size(); // Delete all the entries returned by the query for (int j = 0; j < resultFeed.getEntries().size(); j++) { CalendarEventEntry entry = resultFeed.getEntries().get(j); entry.delete(); } PS: I've looked at the Data API Developer's Guide and the Google Data API Javadoc. These sites are okay, but not great. Does anyone know of additional Google API documentation?

• Jquery + Prototype Question

  - by mikeyhill

  I recently inherited a site which is botched in all sorts of ways. I'm more of a php guy and initially the js was working just fine. I made no changes to the javascript or the any of the include files but after making a few content edits I'm getting errors from firebug. a.dispatchEvent is not a function emptyFunction()protot...ects.js (line 2) emptyFunction()protot...ects.js (line 2) fireContentLoadedEvent()protot...ects.js (line 2) [Break on this error] var Prototype={Version:'1.6.0.2',Brows...pe,Enumerable);Element.addMethods(); protot...ects.js (line 2) this.m_eTarget.setStyle is not a function [Break on this error] this.m_eTarget.setStyle( { position: 'relative', overflow:'hidden'} ); protot...ects.js (line 43) uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE)" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: js/prototype_effects.js :: anonymous :: line 2" data: no] Googling around I found several posts that sometimes jquery+prototype don't play well and rearranging the scripts could fix this issue, however being that I didn't touch these sections I'm not sure where I even need to begin to debug. The previous developer incorporated a head.inc file which loads up prototype, scriptaculous and then many of the pages are in a sub-template loading up jquery for functions like lightbox. The site is temp housed at http://dawn.mikeyhill.com Any help is appreciated.

• Refactoring. Your way to reduce code complexity of big class with big methods

  - by Andrew Florko

  I have a legacy class that is rahter complex to maintain: class OldClass { method1(arg1, arg2) { ... 200 lines of code ... } method2(arg1) { ... 200 lines of code ... } ... method20(arg1, arg2, arg3) { ... 200 lines of code ... } } methods are huge, unstructured and repetitive (developer loved copy/paste aprroach). I want to split each method into 3-5 small functions, whith one pulic method and several helpers. What will you suggest? Several ideas come to my mind: Add several private helper methods to each method and join them in #region (straight-forward refactoring) Use Command pattern (one command class per OldClass method in a separate file). Create helper static class per method with one public method & several private helper methods. OldClass methods delegate implementation to appropriate static class (very similiar to commands). ? Thank you in advance!

• Is it not possible to make a C++ application "Crash Proof"?

  - by Enno Shioji

  Let's say we have an SDK in C++ that accepts some binary data (like a picture) and does something. Is it not possible to make this SDK "crash-proof"? By crash I primarily mean forceful termination by the OS upon memory access violation, due to invalid input passed by the user (like an abnormally short junk data). I have no experience with C++, but when I googled, I found several means that sounded like a solution (use a vector instead of an array, configure the compiler so that automatic bounds check is performed, etc.). When I presented this to the developer, he said it is still not possible.. Not that I don't believe him, but if so, how is language like Java handling this? I thought the JVM performs everytime a bounds check. If so, why can't one do the same thing in C++ manually? UPDATE By "Crash proof" I don't mean that the application does not terminate. I mean it should not abruptly terminate without information of what happened (I mean it will dump core etc., but is it not possible to display a message like "Argument x was not valid" etc.?)

• how to make it easy for users to register at my site?

  - by rob

  I want to make it dirt simple for users coming to my site to register so they can post comments, vote on things, etc. I would like for them to be able to use their facebook id, twitter id, yahoo mail id, gmail id, AIM id, msn id, or whatever else people are likely to have (not necessarily all of those, but the more the better). I want my mom to be able to do it in 30 seconds or less. (that is, no "enter your open id url here" type thing that would confuse her). I prefer they not have to pick a unique name, as that gets annoying as the site gets more users and it gets hard to find one that is unique. What is the best option here? I'm not quite sure about OpenId vs. OAuth, and whether there are other options. And I'd like it to be as simple for me, the developer, as possible (of course!). I don't want to spend forever learning some protocol, nor have to structure my whole app around this. It would be great if there was a site with sample code that is pretty easy to drop in. BTW, StackOverflow is a good example of a site that was easy for me to register for.

• Looking for a good C++/.net book

  - by Michael Minerva

  I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

• Android lifecycle: Fill in data in activity in onStart() or onResume()?

  - by pjv

  Should you get data via a cursor and fill in the data on the screen, such as setting the window title, in onStart() or onResume()? onStart() would seem the logical place because after onStart() the Activity can already be displayed, albeit in the background. Notably I was having a problem with a managed dialog that made me rethink this. If the user rotates the screen while the dialog is still open, onCreateDialog() and onPrepareDialog() are called between onStart() and onResume(). If the dialog needs to be based on the data you need to have the data before onResume(). If I'm correct about onStart() then why does the Notepad example give a bad example by doing it in onResume()? See http://developer.android.com/resources/samples/NotePad/src/com/example/android/notepad/NoteEditor.html NoteEditor.java line 176 (title = mCursor.getString...). Also, what if my Activity launches another Actvity/Dialog that changes the data my cursor is tracking. Even in the simplest case, does that mean that I have to manually update my previous screen (a listener for a dialog in the main activity), or alternatively that I have to register a ContentObserver, since I'm no longer updating the data in onResume() (though I could update it twice of course)? I know it's a basic question but the dialog only recently, to my surprise, made me realize this.

• Is there a jQuery Equivalent of YUI 2 Custom Event Publish/Subscribe Event Model?

  - by Abe

  Hello! I learned how to develop in Javascript using the YUI 2 library and was wondering if there is a jQuery equivalent of Custom Events (http://developer.yahoo.com/yui/event/#customevent) Specifically, I want to be able to define custom events without having to attach the listeners initially. In YUI, I would create a page class and declare different custom events that can be subscribed to. Below is some example code to demonstrate what I want to do, but with jQuery function ListPage() { var me = this; this.initEvent = new YAHOO.util.CustomEvent("initEvent"); this.init = function() { // initialize events, DOM, etc this.initEvent.fire(me); } } In application Javascript, I would then like to subscribe to the initEvent. var page = new ListPage(); page.initEvent.subscribe( function (type, args) { // do stuff here } ); page.init(); Are there any tutorials/examples of something this in jQuery? I understand I can do something similar using bind() and trigger(), but the impression I get is I have to pass in the event handler when I call bind(). Is it possible in jQuery to create the custom event, but pass in the event handler later? I hope my question makes sense. thanks!

• Keeping third-party libraries under a Mercurial project: Sub-repos or not?

  - by fraktal

  Hello, We are developing a closed-source project, versionned with Mercurial. We are using two libraries in our project : One of those libraries is being developed by a third-party. They are using git, and we usually just pull from their repo once in a week to get the latest changes. The other library is being developed by ourselves, and is under active development. It must live in its own public mercurial repository, as it is licensed under LGPL. (It's a fork of a third-party LGPL component, ported to our platform) So my question is: How should I organize the source to ensure that: A developer from our team should be able to get all the source (main project + libraries) with a single "clone" command We should be able to pull easily the latest changes from the libraries, even though one of them is managed by git Should we use mercurial sub-repos functionnality, with hg-git to access to the library under git? Is it well supported by TortoiseHg and BitBucket? (pros: easy to pull library changes / cons: does it works well?) Or should we keep only snapshots of the libraries under our project? (thus, when there are new upstream changes in the libraries, we pull them to a separate place, and then copy the whole source to our project? (pros: will work / cons: pain in the ass, especially for the library that is being developed by ourselves, which is subject to a lot of daily changes)

• Refresh page using cache

  - by cbh

  I am trying to refresh a page, but WANT to use the cache and can't figure out how to do this. There are two situations: If I click in the URL bar and hit enter (or visit the page from somewhere else) it reloads the page/images from the cache. GREAT! If I click on the refresh button or use Javascript to refresh the page it grabs all the images again and takes forever. NOT GREAT! I've tried: top.location.reload(false); and top.location.reload(true); (I'm sending this from in an iFrame) and neither used the cache. I'm avoiding using location so it doesn't end up in the browser history twice. Question: How do I reload the page using the cached images? Is there a different javascript function or is this a mod_expires issue? Thanks for any help in advance! EDIT: (info from chrome: developer tools) When navigating to the page I get "From Cache" for all images When refreshing page I get "304 - Not Modified" for all images (and it takes the time to download each)

• [iPhone] Play video not in full screen mode

  - by Kyo

  Hello, First, excuse my english :) I've read on apple developer website that video playback provides by the framework supports only full screen mode. I will need to develop an application where video can be played in reduce screen mode. I've see that Orange TV make something which looks like what i need to do. http://img218.imageshack.us/img218/1228/tvplayerorange.jpg The application is available on app store but you need to have a subscription to test this application. Whatever, to resume it, we can see video (tv stream video) in a reduce mode and if we click on the screen it switch to a full screen mode. So my question, what i want to do is possible (Orange TV made it) but i wonder the difficulty to make it. It seems that I have to make a video player. If it take a bunch of time, I tkink I will use Media Player Framework of iPhone even isn't the optimal solution for me. Feel free to ask me more details ;) Thank you for your answers.

• iPhone: Same Rows Repeated in Each Section of Grouped UITableview

  - by Rank Beginner

  I have an app that is a list of tasks, like a to do list. The user configures the tasks and that goes to the SQLite db. The list is displayed in a tableview. The SQL table in question consists of a taskid int, groupname varchar, taskname varchar, lastcompleted datetime, nextdue datetime, weighting integer. I currently have it working by creating an array from each column in the SQL table. In the tableView:cellForRowAtIndexPath: method, I create the controls for each task by binding their values to the array for each column. I want to add configurable task groups that should display as the section titles. I got the task groups to display as the section headers. My problem is that all the task rows are repeated in each group under each header. How do I get the correct rows to show up only under the correct section? I'm really new to development period and took on a hobby of trying to teach myself how to develop iphone apps. So, pretty please, be a little more detailed than you normally would with a professional developer. :)

• Solutions to cubefarm lighting

  - by Khorkrak

  So with our recent move to the cubefarm out from our developer friendly shared office, we've altered the environment to reproduce our more programming conducive workspace as much as possible. Fortunately, we we're planted into the same aisle as QA. They're quiet and it's made it easier to pair up to review a problem. They've already unscrewed some of the fluorescent bulbs. We unscrewed the rest. Now the facilities coordinator and HR are wondering what to do. They want the office to have an open, bright and elegant feel to it as does the founder - think IKEA. Fortunately he's usually in the NYC office and rarely stops up where we work. There's some natural light from nearby windows and translucent office walls that ring the farm. So the facility coordinator doesn't understand - do you guys want incandescents overhead or... no we just don't want overhead lights. How to solve this while avoiding having a weird looking office space with a dark spot in the middle. Are there any better solutions - no we can't have an office as that's considered a management only perk.

• How do Oracle Forms compare to Microsoft Access as a "front-end"?

  - by webworm

  I recently started a project where I was set to build an ADP based application in Access 2003. The font end GUI was going to be in Access while all the data resided in MS SQL Server. I say "was", because the powers that be have decided that Oracle Forms might be a better choice than Access and SQL Server. The place where I am doing this work is an Oracle shop where they use Oracle 10g. They also use Oracle Forms quite a bit internally. As for me I am always up for learning anything new. I have always been a rather "eclectic" developer (I work with .NET WinForms, ASP.NET, Java, C#, Python, and Access) so I would not mind moving to Oracle Forms as long as it could do the same things as MS Access (hopefully even more as VBA is rather limited). So my question is this. How does Oracle Forms (10g) compare to MS Access for developing a GUI application? Access uses VBA for it's language, what does Oracle Forms use? I know the Forms app is a Java applet. Does that means you can write Oracle Forms using Java?

• Image.Save(..) throws a GDI+ exception because the memory stream is closed.

  - by Pure.Krome

  Hi folks, i've got some binary data which i want to save as an image. When i try to save the image, it throws an exception if the memory stream used to create the image, was closed before the save. The reason i do this is because i'm dynamically creating images and as such .. i need to use a memory stream. this is the code: [TestMethod] public void TestMethod1() { // Grab the binary data. byte[] data = File.ReadAllBytes("Chick.jpg"); // Read in the data but do not close, before using the stream. Stream originalBinaryDataStream = new MemoryStream(data); Bitmap image = new Bitmap(originalBinaryDataStream); image.Save(@"c:\test.jpg"); originalBinaryDataStream.Dispose(); // Now lets use a nice dispose, etc... Bitmap2 image2; using (Stream originalBinaryDataStream2 = new MemoryStream(data)) { image2 = new Bitmap(originalBinaryDataStream2); } image2.Save(@"C:\temp\pewpew.jpg"); // This throws the GDI+ exception. } Does anyone have any suggestions to how i could save an image with the stream closed? I cannot rely on the developers to remember to close the stream after the image is saved. In fact, the developer would have NO IDEA that the image was generated using a memory stream (because it happens in some other code, elsewhere). I'm really confused :(

• Tips for using Subversion and XCode in a team project

  - by FelipeUY

  Hi to all. I've been working on an Xcode (iPhone) project with three different persons. We have the project on a Subversion repository, but we still don't completely understand some aspects of the Subversion + Xcode methodology: 1) Each time someone does a commit on a single file, it may appear or not in the project of the other developers. Even though the same person that creates the new files, it adds those files to the Repository and then it commits on those files. Why does that happens? Any suggestions? 2) Each person that is involved on the project can't do a "Commit entire project" without causing a considerable headache to the rest of the developers... any idea how this should be done?. The working methodology that we are trying to implement is that only one developer (generally the leader of the project) can Commit the entire project but he must inform the rest of the team, so everybody can be prepared to receive a message asking him to discard his changes and read the new files from the repository. I need suggestions or advice on how to handle a project with multiple developers using subversion. We have read the Subversion handbook, and many other messages on StackOverflow but I still can't find any useful advice. Thanks for any tip!

• Using parameterized function calls in SELECT statements. MS SQL Server

  - by geekzlla

  I have taken over some code from a previous developer and have come across this SQL statement that calls several SQL functions. As you can see, the function calls in the select statement pass a parameter to the function. How does the SQL statement know what value to replace the variable with? For the below sample, how does the query engine know what to replace nDeptID with when it calls, fn_SelDeptName_DeptID(nDeptID)? nDeptID IS a column in table Note. SELECT STATEMENT: SELECT nCustomerID AS [Customer ID], nJobID AS [Job ID], dbo.fn_SelDeptName_DeptID(nDeptID) AS Department, nJobTaskID AS JobTaskID, dbo.fn_SelDeptTaskDesc_OpenTask(nJobID, nJobTaskID) AS Task, nStandardNoteID AS StandardNoteID, dbo.fn_SelNoteTypeDesc(nNoteID) AS [Note Type], dbo.fn_SelGPAStandardNote(nStandardNoteID) AS [Standard Note], nEntryDate AS [Entry Date], nUserName as [Added By], nType AS Type, nNote AS Note FROM Note WHERE nJobID = 844261 xORDER BY nJobID, Task, [Entry Date] ====================== Function fn_SelDeptName_DeptID: ALTER FUNCTION [dbo].[fn_SelDeptName_DeptID] (@iDeptID int) RETURNS varchar(25) -- Used by DataCollection for Job Tracking -- if the Deptartment isnt found return an empty string BEGIN -- Return the Department name for the given DeptID. DECLARE @strDeptName varchar(25) IF @iDeptID = 0 SET @strDeptName = '' ELSE BEGIN SET @strDeptName = (SELECT dName FROM Department WHERE dDeptID = @iDeptID) IF (@strDeptName IS NULL) SET @strDeptName = '' END RETURN @strDeptName END ========================== Thanks in advance.

• How does an ASP.NET programmer go from working on/developing existing sites, to creating one from sc

  - by SLC

  I've been an ASP.NET developer for some time, always working on existing ASP.NET pages, modifying functionality, adding features, tweaking things etc. but have never built a site up from scratch. I've read books on ASP.NET, and they generally talk you through the various features of ASP.NET with a mock up site, but it's always very basic and they jump straight in. The time has come however, to write a site from scratch for a client. I've never done this before. There are design considerations, but like a lot of ASP.NET sites, the basic idea is, you have a site, where users can log in, and save some information like their name and password and address. The site has some functionality, but that's the basic design of a majority of (business-related) asp.net websites I would wager. I know how to program in ASP.NET already on an existing site, but I don't know how to design my own properly that meets the criteria above. I guess the main worry is security. I don't know the best way to handle a simple log-in system that stores user information like their name and password. I understand there are a few approaches to this, but the catch with this project is that it has to be absolutely bulletproof. Maximum security. All those good practices for security, it needs to have them all. I'm not asking what they are, but I am asking where to begin. What should be the first steps after I do File New Project ? Where can I look for information about setting up a secure ASP.NET website? I'll figure out the content and page layout later, it's the framework that is the big thing. Any and all advice would be welcome. I really want to get my first from-scratch project right from the beginning. Just to confuse things, it's possible I will be using MVC, I am not sure if this has any impact.

• Jquery (non-gem) plugin won't work in my rails 3.2 app

  - by jfdimark

  I'm trying to equalize columns in my rails 3.2 app, and while there may be a better way to do it then my current attempt, after hours of trying to make it work I'd like to see if anyone can point out specifically why this jQuery plugin (which isn't a gem) is not working. I'm not getting any errors in the developer console, so it's hard to pin point. Here's the relevant code: The index view, where I've followed the plugin's instructions: div id="column-group"> <div class="equalize span5 offset1 UserProfile"> <% if user_signed_in? %> <h3>Hello <%= current_user.name %>!</h3> </div> <div class="equalize span5 MemberDisplay"> My application.js file, where I've also included the specific js code, so it would definitely be picked up by the application: //= require jquery //= require jquery_ujs //= require bootstrap //= require equalize_column_heights //= require_tree . $(document).ready(function() { $("#column-group").equalize_column_heights("equalize"); }); The jQuery plugin code, which is saved in my vendor/assets/javascripts folder: (function ($) { $.fn.equalize_column_heights = function (equalize_class) { var tallest_column=0; parent_id = "column-group" + $(this).attr("id") + " ." + equalize_class; $(parent_id).each(function(index, value) { if (tallest_column < $(this).height()){ tallest_column = $(this).height(); } }); $(parent_id).each(function(index, value) { $(this).css({'min-height': tallest_column}); }); } }(jQuery)); I've read all the rails guides documentation on the asset pipeline and all the relevant jQuery-rails3 questions on SO, but after several hours, I just can't seem to figure this one out. If anyone can point to other tutorials on how to get non-gem jQuery plugins to work in a Rails 3.2 app then I'd be glad to take a look!

• c++ simple conditional logging

  - by Sunny

  Disclaimer: I'm not a c++ developer, I can only do basic things. (I understand pointers, just my knowledge is so rusty, I haven't touch c/c++ for about 20 years :) ) The setup: I have an Outlook addin, written in C#/.Net 1.1. It uses a c++ shim to load. Usually, this works pretty well, and I use in my c# code nlog for logging purposes. But sometimes, the addin fails to load, i.t. it does not hit the managed code at all for me to be able to investigate the problem from the log files. So, I need to hook some basic logging into the c++ shim - just writing in a file. I need to make it as simple as possible for our users to enable. Actually I would prefer not to ship it by default. I was thinking about something, which will check if a specific dll is present (the logging dll), and if so, to use it. Otherwise, it will just not log anything. That way, when I have a user with such a problems, I can send him only the logging dll, the user will save it in the runtime directory, and I'll have the file. I guess this have to be done with some form a factory solution, which returns either a dummy logger, or if the dll is found, a real one. Another option would be to make some simple logger, and rebuild the shim with or w/o using it, based on directives. This is not the desirable approach, because the shim needs to be signed, and I have to instruct the user to make a backup copy of the "real" one, then restore when done, etc., instead of just saving and deleting a dll. I'd appreciate any good suggestion how to approach it, together with links or sample code how to go after this. Cheers

• Is it a wise decision to go from dev to third line/Tier 3 dev support?

  - by dotnetdev

  Hi, I am an experienced, mid-level developer. However, I recently spotted a job for a company which is small but has a lot of emphasis on training(beyond the basic technical training, but also mentoring, leadership training, etc). The role is 3rd line so still very technical. It's in app support so it's post implementation development rather than pure out-and-out development like I do now (or don't, as the senior devs do all of the interesting work). However, and this is the question - is this sort of career move common? Also, wouldn't a tech support role be a big shock to the system because I've never dealt with customers? I therefore think it's a bad move? Working in dev, I am used to the lack of customer contact and it is all filtered through by my manager. But in tech support, contacting customers/rude customers could be scary. I don't mind fixing other people's mistakes (better than me making mistakes!) and doing post-implementation dev for production systems (will give me a lot of discipline), and I do get bored sitting in the same place looking/talking to the same people in suits (I work in a corporate environment). The company puts A LOT of emphasis on training and prospects, which I don't get in the current (big) company I work at. Any advice on how to handle tech support is appreciated! Thanks

• Page Entirely Blank Despite Having Source Code! (TinyMCE, FireFox)

  - by Chris Cooper

  Alright guys, here's a tough one... In reference to this page. The page will seemingly randomly not display the output of server when using Firefox (version 3.5). I have not seen this problem occur in Safari or IE. The best way to have the problem occur is just reload the page about 10 times and it ought to have happened by then, and once it does - it'll continue on subsequent refreshes until you change the page. The problem is literally the browser not displaying the output (code). Viewing the source shows all the appropriate code yet the browser displays a blank white page. The web developer and firebug plugins don't show any errors that would indicate the problem. I have tested this on a separate system and OS and it occurs in Firefox on that system as well. The problem did not occur until after TinyMCE (A Rich Text Editor JavaScript library for textareas) was added to the project. TinyMCE works however, where it should. I know this is a confusing problem, but I am completely lost as to what could be causing this significant issue. Thanks in advance. EDIT: If it's any help... I've noticed that if I cause a css file error by changing a stylesheet source to something non-existant (xxx.css), the page will continuously display without a problem (besides whatever related css not showing due to the src change). I've also noticed that causing any simple javascript error with some bad code will cause the page to load properly continuously (besides of course javascript not running on the page). EDIT#2: Moving all <script> tags down at the tail of the <body> 'fixes' (well, hides) this error and the page shows normally. A band-aid.

• Android Facebook RequestListener

  - by Marcus King

  I'm new to Java, but have been a .NET developer for years now and I am a bit confused about the point of the RequestListener object as I can't retrieve the results of my asynchronous calls on the UI thread from what I can tell. My research has told me I should not use singletons or the application context object for getting and storing data. I could use sqlLite, but the data I need is too transient to bother. I would like to know how to have the asyncfacebookrunner object report back it's responses to the UI thread so I can proceed to make decisions between my own api and the objects returned to me from the facebook calls I am making in the async calls. Am I missing something? I can't seem to find a way to get data out. I can pass a Bundle in, but I'm not too sure how to get data out. I would think I would pass it an Intent object to retrieve, but I am not seeing it. I think my eyes are crossed from lack of sleep at this point. Any help here?
