• Windows Mobile Development on MacBook Pro?

  - by Ted Nichols

  I am a frequent Windows Mobile application developer in need of a new development laptop. I am considering a MacBook or Macbook Pro running either Fusion from VMWare or Parallels Desktop. This will give me the option to port my applications to the iPhone depending on what MS does with WM 6.5 and 7. Has anybody tried doing Windows Mobile development using Microsoft Windows Mobile Device Center (or ActiveSync) and VS2008 on the MacBook Pro using one of these virtual machines? Does the device emulator work properly? What about debugging a Windows Mobile device over a USB cable? In general, do most USB drivers (non HID) designed for Windows work under these virtual machines? Thanks.

• How much should I charge for Rails programming?

  - by Oskar Gantt

  I have been asked to quote an hourly rate for freelance programming for a Rails project. Although it would be my first paid project on Rails, I know the technology well from personal projects and have a decade of professional programming experience. This would be my first freelance project ever, so I have no idea how to find out what the going rate for my services should be. Obviously, if I quote a rate that is too high, they may choose someone else - too low and I may feel cheated later on. Any suggestions? Update: I am in NYC and the project is scheduled for 6 months to a year (but this seems unrealistic - I think it will be a multi-year project). I would develop on site (at a corporate location) with one other developer and the project would consist of about 200 custom-built pages initially. 10 hour days with weekends and additional overtime as required. The customer has given no information about how much they will pay - "a competitive rate" - they want me to start the discussion.

• What are your build and release steps? When to increment build numbers?

  - by Ed

  I am having trouble defining and automating my build process despite simple requirements: Every build should have a unique build number. Every tagged release should be reproducible What I have: A C++, Red Hat Enterprise Linux 5.x, Subversion development environment. A build machine ( actually a virtual machine ) A version.h file with #defines for major, minor, and buildnumber. A script for incrementing the version.h buildnumber. A rpmbuild spec file that exports the tagged Subversion source, builds, and makes the rpm installer packages. Questions: Assuming multiple developers per project, when should the build number be incremented and version.h file be checked-in? The build machine? Some sort of Subversion hook? Pre-build or post-build? Thanks in advance for those willing to take the time to share their experience with build processes. -Ed Linux newbie. Former Windows C++/.NET developer.

• How is your mac setup for windows development?

  - by Matt Brailsford

  Hi Guys, I'm looking at buying a MacBook Pro to replace my tiring laptop. My day to day job is as a .NET web developer so I am looking to use VMWare Fusion to run VS and SQL server etc. As I've not run my dev environment in a VM before, I would like to know how others are setup. What apps to you have installed? In which environment? Where do you store your files? Within each environment, or some shared drive? Are there any gotchas? Or essentials I should know. Many thanks Matt

• Do you have to install the REST starter kit in asp.net to access APIs?

  - by jonhobbs

  Hi, I'm currently trying to access a REST API for the first time using visual web developer 2008 express edition. Every article I have found says you have to install the WCF REST starter kit which is a .msi file, which would suggest that I have to install it on my machine and presumably our server too. My question is this. Is there a non installable version that I can use, e.g. just by dropping DLLs into the Bin directory and then using the classes contained. Or is there more to it than that and am I just getting very confused about how it works? Jon

• Importing large datasets on iPhone using CoreData

  - by Matthes

  Hi there, I'm facing very annoying problem. My iPhone app is loading it's data from a network server. Data are sent as plist and when parsed, it neeeds to be stored to SQLite db using CoreData. Issue is that in some cases those datasets are too big (5000+ records) and import takes way too long. More on that, when iPhone tries to suspend the screen, Watchdog kills the app because it's still processing the import and does not respond up to 5 seconds, so import is never finished. I used all recommended techniques according to article "Efficiently Importing Data" http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CoreData/Articles/cdImporting.html and other docs concerning this, but it's still awfully slow. Solution I'm looking for is to let app suspend, but let import run in behind (better one) or to prevent attempts to suspend the app at all. Or any better idea is welcomed too. Any tips on how to overcome these issues are highly appreciated! Thanks

• How to schedule daily backup in SQL Server 2008 Web Edition

  - by Xenon

• Please advise on handling the existing geek

  - by ranja

  Quick Story: I started a new job where everyone funneled their questions to 'the geek'. Being an experienced developer, I can do most of my assignments without consultation with the geek - thinks such as how to select the top 10 rows in a table. Question: Is there a preferred way of handling these cases without offending the existing geek while ensuring the best solution gets implemented? My issue is the the existing geek is very young and makes a lot of mistakes, but still sounds authoritative because the other coders are just out of school and don't know better.

• problem with sql job and datetime parameter

  - by geoff swartz

  Another developer created a stored procedure that is set up to run as a sql job each month. It takes one parameter of datetime. When I try to invoke it in the job or in just a query window I get an error "Incorrect syntax near ')'" The call to execute it is... exec CreateHeardOfUsRecord getdate() When I give it a hard coded date like exec CreateHeardOfUsRecord '4/1/2010' it works fine. Any idea why I can't use getdate() in this context? Thanks.

• ODBC Connection Pooling

  - by beansy

  I have inherited a suite of .Net c# applications from a developer which talk to an Informix database on a unix server. Instead of using the usual practices for managing the database connections (disposable pattern / "open late / close early"), the code seems to open one ODBC connection when each app loads and doesn't close it. Connection pooling is turned via the ODBC administrator. Is there any way of seeing how many ODBC connections are open? What is the effect of turning off connection pooling? Am I right in thinking the .NET framework will use connection pooling anyway?

• Jquery: How can I place triggers on images already cached?

  - by FLX

  Please see: hxxp://flx.me/h/0504/ Source: hxxp://pastebin.com/bDh5k3Qd jquery.preload-min.js: hxxp://jquery.com/plugins/project/Preload jquery.jplayer.min.js: hxxp://www.happyworm.com/jquery/jplayer/0.2.4/developer-guide.htm I'm using jquery.preload-min.js to preload images and to send a play trigger to jquery.jplayer.min.js to start playing a mp3 file. This works great when viewing the page for the first time (or force reloading all content). However, when the image has already been cached, it doesn't use the preloading script and thus does not send the play trigger to jplayer. How can I make it send a play trigger even when the image is cached? Thank you in advance, Dennis

• How to tell if a user is a fan of the fan page

  - by Dominic Godin

  Hi, I'm working on a FBML fan page for a client. I need to perform a check to see if the current user is a fan of the page. I tried using the JavaScript API but I've found this is not compatible with FBML. I have looked through the FBML page on the developer wiki and found checks for practically everything else but no is user fan check. Any pointers in the right direction would be most appreciated. Thanks in advance.

• Wicket : Can a Panel or Component react on a form submit without any boilerplate code?

  - by MRalwasser

  I am currently evaluating Wicket and I am trying to figure out how things work. I have a question regarding form submit and panels (or other components). Imagine a custom wicket panel which contains a text field, doing as-you-type validation using ajax. This panel is added to a form. How can the Panel react a form submit (let's say because javascript/ajax is unavailable)? I am currently only aware of one solution: calling a panel's method inside the Form onSubmit() method. But this seems not like a "reusable" approach here, because I have to add boilerplate code to every form's onSubmit() which contains the panel (and every developer which use the panel must know this). So here comes my question: Is there any way that a Panel/Component can "detect" a form submit in some way? Or is there any other solution beside this? Thank you.

• Need an Android Devloper with access to a Motorola Droid of Nexus One (Android 2.1)

  - by Rob Kent

  Apologies if this is the wrong place to ask this. I have an Android app on the market that has a reported problem on Droid and Nexus One (both with Android 2.1). I don't have access to the handset and cannot find anyone with one where I live. The problem I'm experiencing is partially explained at: http://stackoverflow.com/questions/2700983/problem-saving-file-on-motorola-droid-android-2-1. If you are an Android developer with either of those handsets, I'm happy to pay a reasonable fee if you'll debug the app for me. I'll send you the source. Please email me at [email protected]

• facing outsourced wages, can i still eat and survive as a computing science major ?

  - by wefwgeweg

  offshore outsourced programmers charge fraction of what costs a North American developer. should I still pursue my major as computing science ? Why would companies spend more on North American/local developers where they can get the same quality if not better job done offshore ? I am just concerned for the development labor market, the free market wants the lowest cost provider. not just programming but many high skilled labor such as engineering, scientists, artists and etc. perhaps i should become a lawyer ?

• Is it considered a good/bad practice to configure tomcat for deploying certain apps?

  - by Roman

  Disclaimer: I've never used technique which is described below. That's why there may occur some mistakes or misunderstandings in its description. I heard that some teams (developers) use 'pre-configured' tomcat. As I understand they add different jars to tomcat \lib folder and do something else. Once I've read something about recompilation (or reassembly?) of tomcat for certain needs. Just yesterday I heard a dialog where one developer sayd that his team-mates were not able to deploy the project until he would give them configured tomcat version. So, I wonder, what is it all about and why do they do it? What benefits can they gain from that?

• Using .htaccess to replace backslash in URL with forward-slash

  - by DamienL

  I realise that a backslash should never appear in a URL in a form other than a URL escape code, however in this case the URL's are being generated by a .NET application for generating flashbooks. I have contacted the developer of this application with a bug report. In the interim i would like to use .htaccess to rewrite the offending backslashes. This is how the URLs appear in fiddler debugging proxy. www.example.com/folder/folder/thumbs%5C1.jpg I am using Firefox and it looks as though Firefox is translating them into the URL encoded equivalent ( \ == %5C1 ). Interestingly IE translates the backslash into a forward-slash automatically (not adhering to standards but convenient in this case). Is there a way to use .htaccess to rewrite all \ to /?

• Can't read query string if default index file name is omitted?

  - by Mike

  Is there an issue with IIS or ASP Classic where *Request.ServerVariables("QUERY_STRING")* returns blank if no default file name is given in the URL? On my local developer machine, I can do http://localhost/xslt/?opcs/abc which returns "opcs/abc". However, on our ancient web server, it returns nothing. I have to explicitly give it the default file name in the URL. Like so http://localhost/xslt/default.asp?opcs/abc While nothing too major, it is a little bit of a annoyance. One way I can maybe think of remidying the problem is have Javascript read the URL and return everything after the ?. Unfortunately, I do not know what version of IIS or ASP we are using. Thank you.

• Avoiding cookies while requesting static content

  - by Abdel Olakara

  I just did an audit of one of my web application page (built using ASP.Net and running on development server) using Google chrome's developer tool. One particular warning caught my eyes: Serve static content from a cookieless domain (5)! Here is my screen shot (http://yfrog.com/7eauditresultp) as well. I would like to know is it possible to avoid cookies for these kind of requests. I see that there is no cookie requests for javascript files as well. I it possible to avoid cookies in the header for these files as well? and why didn't the browser attach cookies for javascript files and attach for CSS and image? Any thoughts and suggestions are welcome

• iPhone Development on Hackintosh

  - by espais

  My question is in regards to developing code for the iPhone / iTouch. What with Apple's transition to the Intel platform for their chip, it is obviously now possible to run their OS on a PC. So, with that, and my inherently cheap nature, I was wondering if it was possible to bypass the purchase of a refurbished Mac by running the iPhone SDK on a Hackintosh? As I am more of a hobbyist then a serious developer at present, I'd basically like to get my feet wet before fully committing to this endeavor. In the long term I know that it would be better to purchase a Mac...

• what pattern to use for multi-argument method?

  - by Omid S

  I have a method with the following signature: foo (Sample sample, Aliquot aliquot) "foo" needs to alter a Sample object, either the first argument or from the second argument it can extract its Sample. For example: foo (Sample sample, Aliquot aliquot) { Sample out = null; if (sample != null) out = sample else out = aliquot.getSample() return out; } But that is so un-elegant, other than reading the API a developer does not know the reference of the first argument overrides the Sample of the second argument. Now, I could change "foo" to foo (SomeMagicalObject bar) where SomeMagicalObject is a tuple for Sample and Aliquot and holds some logic ... etc. But I am wondering, are there some patterns for this question?

• Building an Issue Trecker Plugin for TortoiseSVN

  - by Oded

  I've read a lot about IBugTraqProvider interface and implementing an issue tracker into the commit dialog of TortoiseSVN. IBugTraqProvider is written here. Is there a more simpler way not to do it, building the plug-in and installing it on TortoiseSVN. The Document is not that clear that a developer can create its own plugin. I'm working with SalesForce as the Issue Tracker, and retrieved the WSDL file to integrate with the Working Items. Now I need to know how to connect it to ToortoiseSVN. Please any suggestions?

• Please list here your deliberate practices in software development...

  - by JDelage

  What are your deliberate practices in relation with your work as a software developer / professional, or as a CS student? Deliberate practice are exercise and repetitions targeted specifically at an individual's weak points and meant to consistently stretch / grow someone's ability. It was described in this Anders Ericsson paper. To qualify as a deliberate practice, the exercise must satisfy the following: Is not inherently enjoyable. Is not play or paid practice. Is relevant to the skill being developed. Is not simply watching the skill being performed. Requires effort and attention from the learner. Often involves activities selected by a coach or teacher to facilitate learning. Please answer with one practice per answer. I'll seed the question with one possible answer.
