• Project management estimating time, budget and product pricing

  - by dr_hoppa

  I have been a software developer for a while but was not interested in the above topics, currently I am put in the position of wanting to learn more about them but don't have a clue where to begin. I have done task estimations and I can do decent ones, but have little/none experience in the field of budget/product pricing and would want to learn more. Do you have any suggestions of good resources that I could look up in order to learn more (eg. books, blogs, ...) This need arised while talking to a friend about management and he brought up management terms that I wasn't aware of (eg. KPI, ...)

• Is Microsoft's Ribbon UI really that great, from a usability perspective?

  - by Thomas Owens

  The first time I ever used it was at my current job. Among my coworkers, the feelings toward it for usability are mixed. The other developer doesn't really care one way or the other, as long as Office does everything he needs it to do when writing reports. The top manager likes it because it feels natural, and I feel the same way. But another coworker finds in klunky and hard to use (although she admits that she only uses it at home as her machine hasn't been upgraded yet, and that might change if she uses it more often at work). So - is the Ribbon UI really that innovative? What qualities about it make it a good or bad user interface mechanism? Possibly related: Adoption of the Ribbon UI

• Get a list of Android phone contacts only on Eclair and above?

  - by Rob Kent

  I want to show the user a flattened pick list of all their contacts phone numbers and it must work from versions 1.6 up. I have read the related questions on SO and the Android documentation for Eclair (http://developer.android.com/resources/articles/contacts.html#legacy). The problem is, even splitting my code into a factory class and specific implementations does not work for me because using Contacts.CONTENT_URI only shows contacts not individual numbers. What I need is this for version 1.6 Intent intent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); startActivityForResult(intent, REQUEST_PICK_CONTACT); And the equivalent for 2.0 and above. Even if I get their example to work, by building against the 2.1 API am I not stopping my app being visible on the Market to users with earlier versions of the OS? I can't launch it against a 1.6 emulator, for example.

• Optional structural typing possibilty in C++ or anyother language?

  - by ambhai

  In C++ how to tell compiler that Ogre::Vector3 IS_SAME_AS SomeOtherLIB::Vector3 ? I feel that.. in languages like c++ which are not structural typed but there are cases when it makes sense. Normally as game developer when working with 4+ libraries that provide sort or their own Vector3 implementation. The code is littered with ToOgre, ToThis, ToThat conversion function. Thats a lot of Float3 copying around which should not happen on first place. Is in C++ or any other languages where we dont have to convert (copying) from one type to another which is essentially the samething. But any solution in C++ as most of the good gamedevs libs are for c/c++.

• Enforcing an "end" call whenever there is a corresponding "start" call

  - by Jeff Meatball Yang

  Let's say I want to enforce a rule: Everytime you call "StartJumping()" in your function, you must call "EndJumping()" before you return. When a developer is writing their code, they may simply forget to call EndSomething - so I want to make it easy to remember. I can think of only one way to do this: and it abuses the "using" keyword: class Jumper : IDisposable { public Jumper() { Jumper.StartJumping(); } public void Dispose() { Jumper.EndJumping(); } public static void StartJumping() {...} public static void EndJumping() {...} } public bool SomeFunction() { // do some stuff // start jumping... using(Jumper j = new Jumper()) { // do more stuff // while jumping } // end jumping } Is there a better way to do this?

• MySQL date query only returns one year, when multiple exist

  - by Bowman

  I'm a part-time designer/developer with a part-time photography business. I've got a database of photos with various bits of metadata attached. I want to query the database and return a list of the years that photos were taken, and the quantity of photos that were taken in that year. In short, I want a list that looks like this: 2010 (35 photos) 2009 (67 photos) 2008 (48 photos) Here's the query I'm using: SELECT YEAR(date) AS year, COUNT(filename) as quantity FROM photos WHERE visible='1' GROUP BY 'year' ORDER BY 'year' DESC Instead of churning out all the possible years (the database includes photos from 2010-2008), this is the sole result: 2010 (35 photos) I've tried a lot of different syntax but at this point I'm giving in and asking for help!

• Documenting software architectures that serve multiple markets

  - by wsb3383

  Hello, I'm the lead developer/architect wanna-be on a J2EE based system/platform at work that serves both real estate and automotive markets. The systems consists of a set of database back ends, web services and two web clients. The platform ends up serving 3 different products: an internal vehicle inventory system for use by company analysts, an external dealer management system (commercialized product), and a real estate inventory system (commercialized). In other words, it follows a software product lines approach....My question is, I'm having trouble communicating to other technical and some business people how this platform architecture is one system that serves multiple markets (by leveraging some existing assets combined with minor modifications)....Is there a formal modeling language that can simplify communicating this intent? I should note that I haven't read much about software product lines, so I'm not sure if there is actually a standard modeling approach to SPL that i'm not aware of....I'm also interested in knowing if there are special configuration management practices for such systems. thanks,

• What is your company's stance on Developers using Laptops?

  - by codepunk

  I am a developer and my company is moving towards a "no laptop" policy in fear of them being lost or stolen and source code being compromised. Now I don't work for NASA, the military or anything labeled Top Secret but our code is very important to our business nonetheless (as all source code would be). I'll be honest, I disagree with this policy against laptops and wanted to see what others think. I'd like to know: What is your team/company's stance on laptops Your company's size and/or field (small, medium or large, Fortune 500, etc). Whether you've had to take any extra precautions (signing any additional legal, ensure your hard drive is encrypted, etc). Thanks!

• Breakdown of this Ruby code?

  - by randombits

  Would anyone be kind enough to dissect the merge! method? Its usage of conditions and variable assignment looks rather terse, and I'm having a difficult time following it. Would love to hear a Ruby-savvy developer break this apart. module ActiveRecord class Errors def merge!(errors, options={}) fields_to_merge = if only=options[:only] only elsif except=options[:except] except = [except] unless except.is_a?(Array) except.map!(&:to_sym) errors.entries.map(&:first).select do |field| !except.include?(field.to_sym) end else errors.entries.map(&:first) end fields_to_merge = [fields_to_merge] unless fields_to_merge.is_a?(Array) fields_to_merge.map!(&:to_sym) errors.entries.each do |field, msg| add field, msg if fields_to_merge.include?(field.to_sym) end end end end

• Is there a way put a timestamp in the file header automatically when saving in Eclipse?

  - by George

  I am a PHP developer using Eclipse PDT. I would like a timestamp put automatically in my file headers whenever I save the file. Maybe as a replacement of a variable. Let's say I use this header in a file: /** * ${filename} * ${timestamp} */ When I save the file I would this to be replaced with: /** * Myfile.php * 4/20/2010 19:04 */ It would also be ok if there is a macro that would add a line at the very beginning of the file just containing a timestamp. Anybody with an idea? Regards, George

• Solution: Android INSTALL_FAILED_INSUFFICIENT_STORAGE error.

  - by Andrew Smith

  The INSTALL_FAILED_INSUFFICIENT_STORAGE error is the bane of every Android developer's life. It happens regardless of app size, or how much storage is available. Rebooting the target device fixes the problem briefly, but it soon comes back. There are hundreds (if not thousands) of message board posts from people asking why the problem occurs, but the folks at Google are frustratingly silent on the issue. There is a simple workaround. If your test device is running Android 2.2 or later then add the android:installLocation attribute to your application's manifest file, with the value "preferExternal". This will force the app to be installed on the device's external storage, such as a phone's SD card. For example: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.andrewsmith.android.darkness" android:installLocation="preferExternal" This is more of a band-aid than a fix, and it may not be ideal if you want your finished app to install on the device's internal memory. But it will at least make the development process a lot less frustrating.

• Visual Studio 2005 Ignores Preprocessor directives during compile

  - by miked

  We just got a new developer and I'm trying to set him up with Dev Studio 2005 (The version we all use at this office), and we're running into a weird problem that I've never seen before. I have some code that works perfectly on my system, and he can't seem to get it compiled. We've tracked the issue down to his copy of dev studio ignoring the preprocessor directives. For example, in the project properties under C/C++|Preprocessor|Preprocessor Directives, I add DEFINE_ME. Which should translate to a /D"DEFINE_ME" for the compiler. And it does in my development environment, but it doesn't on his. I verified that when he checks out the code from the source repository, that he has the same version of the code I do. And if I look in his Project Properties, all of the directives are there. For some reason they're just not getting passed down to the compiler. Any Ideas?

• Netbeans C++ not finding standard libraries (Macintosh)

  - by Grue

  Hello everyone! I am trying to use Netbeans 6.7 (on a Mac) to create C++ applications. I started out with the standard "Hello World," just to test if everything was working correctly. First try std and could not be found. So I tried reinstalling the developer tools on my Mac OS X disk. After that Netbeans updated its c++ compiler info, but still cannot find std or . Odder than this XCode seems to be working with C++ perfectly fine. Any help fixing this would be greatly appreciated.

• What are good resources to learn Coldfusion for a job application...

  - by NoMoreZealots

  The job title is "ColdFusion Developer." I have bit's HTML and Javascripting experience, but mostly have worked in the "harder" languages such as C and C++ with occational flurries of assembly. I'm currently employeed, but in the current job climate I figure it can't hurt to be looking around and applying for other positions. Plus according to the friend who sent me the job posting, it is suppose to pay "very well." They left my office to work for this company themself so I figure it's a reasonable evaluation of the company. I don't know if there are any free tools that I could use to get my feet wet and bone up for an interview, or what sort of literature is decent for the ColdFusion. Plus any ideas on how to tune a resume for it would also be helpful.

• Experience using IRC to coordinate software development?

  - by momeara

  I am part of a growing software project with at least 200 active developer in 10 locations. I would like to set up an on-line chat forum for developers because I think it would help to coordinate efforts. We have an email mailing list but I feel like some questions or announcements are too informal to send to everyone while mentioning it in a chat forum might be a useful community resource. I have never participated in a software project that used an on-line chat forum so I would like to hear about peoples experiences. I am particularly interested in technical issues: Use of IRC vs. alternative platforms; how to manage access, eg. for developers only, allowing users to participate; the value of requiring certain announcements to be made on the chat forum eg who is resolving broken builds etc. If I pitch the idea to the community I would like to have some good arguments why it would be a good idea and some prospective of its usefulness in other software projects.

• Anyone run recurring payments in their website? Preferably; Paypal API

  - by James

  I'm wrapping up my startup and will need to implement Paypal API into my sign up page. Does anyone use recurring payments via Paypal API integrated into their billing? Better yet, guide me to a trustable developer with experience or will I have to use Elance? I need it to go to a welcome/get started screen in their logged in account once they hit the 'create account' button after filling out billing info. I was also wondering, can you leave the CSC (3 digit security code) field out with integration, because it makes things very hard for recurring payments. I'd like to stick with Paypal, as I have been very satisfied with them for a few years now; I already checked out Chargify, authorize.net, etc. I'd love to see someone with something like this set up already to take a look at and ask a few questions.

• How to convert an Info.plist file from mac os project to iphone project?

  - by Tom Pace

  I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's Info.plist files are Mac OSX project Info.plist files. This is an iPhone engine, and so I cannot understand why the Info.plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings. Edit - Opening the plist file in Xcode or Property List Editor and then trying to add a key such as "Icon already includes gloss and bevel effects" will not work in this iPhone project because it is not in the list. However, "Cocoa Java Application" and others are available!

• Installed Android on Mac, cannot find SDK

  - by David Matuszek

  Using Mac OS X 10.6.2, Eclipse SDK 3.5.2. I installed the Android plugin, following the instructions at: http://developer.android.com/sdk/eclipse-adt.html In the next section (step #3) it says: For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory. I cannot find such a directory. When I try some other directory, it says the directory has no 'tools' folder, so I've searched for a 'tools' folder, but none of those found (of 15 or 20) appear to be Android. Where is this directory??? --Dave [email protected]

• SVNServ deny write access to a directory via wildcard match.

  - by Wes

  Hi, We have a requirement that every piece of code that makes it into production will be reviewed by a senior developer. The way I have envisioned this working is by a naming convention for branches that regular developers cannot check code into. Following the SVN recomended directory structure this translates into something like. [project-name]/trunk/ [project-name]/branches/ [project-name]/branches/development-01 [project-name]/branches/development-02 [project-name]/branches/task-increasefontsize [project-name]/branches/release-01 [project-name]/branches/release-02 [project-name]/tags/ So in the authz file I would like to have something like the following [/] @developers = rw [/*/branches/release-*] @developers = r @senior_developers = rw However I can't find any evidence that SVN supports * (or any other wildcard character). Is such a thing possible or do I need a pre-commit hook?

• NET Framework Validation Library

  - by Kane

  As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

• How to get started with embedded systems in the aircraft or submarine industries?

  - by Jason

  Hi, Not 100% sure how to frame this question but here goes... I currently work as a Rails developer but want to work on more substancial / "meaty" projects and have always been very interested in embedded systems, especially systems that run on aircraft and especially submarines.....I know strange combination. I have been doing some searching & found lockheed martin produces a lot of underwater systems for various navys around the world e.g. http://www.naval-technology.com/projects/nssn/ However, there is very little information about what software is used within these systems, what OS's they use or anything else "technical", presume there is a lot of C / C++ involved but that is just a guess... so its hard to know where to even begin learning what is required to potential work in these areas. Just wondering if anyone has any experiance working with or more information about embeddeed systems in either the airline (onboard flight systems) or especially submarine systems? Thanks!
