• How is your Mac set up 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

• Good reasons why to not use XIB files?

  - by mystify

  Are there any good reasons why I should not use XIB / NIB files with an highly customized UI and extensive animations and super low memory footprint needs? As a beginner I started with XIB. Then I figured out I couldn't do just about everything in them. It started to get really hard to customize things the way I wanted them to be. So at the end, I threw all my XIBs away and did it all programmatically. So when someone asks me if XIB is good, I generally say: Yeah, if you want to make crappy boring interfaces and don't care too much about performance, go ahead. But what else could be a reason not to use XIB? Am I the only iPhone developer who prefers doing everything programmatically for this reasons?

• Defining - and dealing with - Evil

  - by Chris Becke

  As a software developer one sometimes gets feature requests that seem to be in some kind of morally grey area. Sometimes one can deflect them, or implement them in a way that feels less 'evil' - sometimes - on reflection - while the feature request 'feels' wrong theres no identifiable part of it that actually causes harm. Sometimes one feels a feature is totally innocent but various anti virus products start tagging one as malware. For example - I personally consider EULAs to (a) hopefully be unenforceable and (b) a means by which rights are REMOVED from consumers. However Anti Virus scanners frequently mark as malware any kind of download agent that does not display a EULA. Which to me is the result of a curious kind of double think. What I want to know is - are there any online (or offline) resources that cover evil software development practices? How can I know if a software practice that I consider dodgy is in fact evil enough to consider fighting?

• Tab versus space indentation in C#

  - by Lars Fastrup

  I sometimes find myself discussing this issue with other C# developers and especially if we use different styles. I can see the advantage of tab indentation allowing different developers to browse the code with their favorite indent size. Nonetheless, I long ago went for two space indentation in my C# code and have stuck with it ever since. Mainly because I often disliked the way statements spanning multiple lines are sometimes messed up when viewing code from other developers using another tab size. Recently a developer at one of my clients approached me and asked why I did not use tabs because he preferred to view code with an indentation size of 4. So my question is: Which style do you prefer and why?

• Is there Java counterpart for Aspnet 4's <%: %> XSS prevention?

  - by Tomas Tintera

  I'm developer moving from C# to Java. Heard about new ASP net feature. <%: %. It renders object with html encoding. Only these impolementing IHtmlString interface are not encoded (to prevent double encoding). See more in http://weblogs.asp.net/scottgu/archive/2010/04/06/new-lt-gt-syntax-for-html-encoding-output-in-asp-net-4-and-asp-net-mvc-2.aspx Is such cute tool in Java side? I mean a way to output a string to webpage and (not)encode it based on it's type.

• 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.

• R mlbench exapmle

  - by Johan B.

  I heard R is the "de facto" language amongst statistical software developers, and I'm giving it a try. I already know the basics, but it still looks "weird" to me (a C developer). I think it would be very useful to see a working example to see how a real R program is built. I thought that an R solution for any of the mlbench problems would be optimal, because I'm already familiar with it and it would allow me to compare it to other languages, but any other "toy problem" example is welcome. Thank you.

• Identifying PHP unused variables (in Emacs)?

  - by Roberto Aloi

  Is it somehow possible to identify unused variables in a PHP file in Emacs? With other languages, this is possible by using tools such as flymake. I've already enabled Flymake to show syntax errors for my PHP files on the fly, but still it's frustrating that PHP logic errors are sometimes due to situations like: <?php $foo = whatever(); $bar = something($fo); ... Note the typo on $foo that will contribute to the developer's headache and to his exorbitant use of coffee.

• How do I do high quality scaling of a image?

  - by pbhogan

  I'm writing some code to scale a 32 bit RGBA image in C/C++. I have written a few attempts that have been somewhat successful, but they're slow and most importantly the quality of the sized image is not acceptable. I compared the same image scaled by OpenGL (i.e. my video card) and my routine and it's miles apart in quality. I've Google Code Searched, scoured source trees of anything I thought would shed some light (SDL, Allegro, wxWidgets, CxImage, GD, ImageMagick, etc.) but usually their code is either convoluted and scattered all over the place or riddled with assembler and little or no comments. I've also read multiple articles on Wikipedia and elsewhere, and I'm just not finding a clear explanation of what I need. I understand the basic concepts of interpolation and sampling, but I'm struggling to get the algorithm right. I do NOT want to rely on an external library for one routine and have to convert to their image format and back. Besides, I'd like to know how to do it myself anyway. :) I have seen a similar question asked on stack overflow before, but it wasn't really answered in this way, but I'm hoping there's someone out there who can help nudge me in the right direction. Maybe point me to some articles or pseudo code... anything to help me learn and do. Here's what I'm looking for: 1. No assembler (I'm writing very portable code for multiple processor types). 2. No dependencies on external libraries. 3. I am primarily concerned with scaling DOWN, but will also need to write a scale up routine later. 4. Quality of the result and clarity of the algorithm is most important (I can optimize it later). My routine essentially takes the following form: DrawScaled( uint32 *src, uint32 *dst, src_x, src_y, src_w, src_h, dst_x, dst_y, dst_w, dst_h ); Thanks! UPDATE: To clarify, I need something more advanced than a box resample for downscaling which blurs the image too much. I suspect what I want is some kind of bicubic (or other) filter that is somewhat the reverse to a bicubic upscaling algorithm (i.e. each destination pixel is computed from all contributing source pixels combined with a weighting algorithm that keeps things sharp. EXAMPLE: Here's an example of what I'm getting from the wxWidgets BoxResample algorithm vs. what I want on a 256x256 bitmap scaled to 55x55. And finally: the original 256x256 image

• What is the relationship between IRimTable and PersistenceStore?

  - by Martin

  The BlackBerry Desktop API has the interface IRimTable which apparently maps an "application database" on a BlackBerry device to a virtual structure (i.e, IRimTable has IRimRecords, each of which has IRimField) that developer can browse the handheld device data when it is connected to a desktop computer. Meanwhile, applications in the handheld device can store its data in PersistenceStore databases. The point where I'm stuck is the PersistenceStore API doesn't define any Table or Records or Fields. Does anybody knows what is the relationship between these two classes? And how does the mapping work (if at all) ?

• Any foundation to administrate an Android open source application?

  - by Nicolas Raoul

  Our open source application is quite popular, and we are many developers. The app uses my Android Market account, and I shared the keys with a developer. But if both of us disappear, the application's Market account will be lost, and all users trapped. Giving the keys to all developers is not a solution either, for security reasons. Is there a foundation (like in Mozilla Foundation or Apache Foundation) that could accept to hold our Android Market account and release new versions in accordance with their own guidelines and our community consensus? There are quite a lot of Open Source foundations, but I could not find any that tackles this particular aspect of Android applications.

• Dealing with Anti-Microsoft Trolls on The Internet

  - by FlySwat

  I'm an active member on Programming Reddit, but I'm one of the few C# advocates there. I could write up a 3 paragraph explanation of how to do something there, just to have it voted into the negatives because I used C# as an example. As a developer using the "Microsoft Stack", how do you handle the trolls and bigots in the online world? These are the kind of people who say things like "M$", or that Vista sucks without ever booting up. Do you just ignore the trolls?

• How to stop Javascript from showing default image and only text for link?

  The Javascript below has a default image, but I would like display text "only text url" for this link instead of this button at this link http://developer.mixi.co.jp/wp-content/uploads/2010/09/bt_check_1.gif that this script defaults to.

• What alternatives are there in OS projects for c# similar to Joomla/Mambo/Drupal?

  - by Joseph

  I'm beginning a project with a client to build a web application and I'm a little stuck on which solution to go with. I've used Joomla for many clients in the past, but this client has specific requests that I KNOW I'm going to have to build myself. The problem I'm facing is that I work full time under the .NET spectrum and while I am a novice developer in PHP, and I've been studying Joomla's plug in architecture for about a month now, I am a lot more comfortable building something in ASP.NET than I am in PHP. My question is, what OS projects are out there that have a similar community following as Joomla/Mambo/Drupal, along with a plug in architecture that is somewhat akin to Joomla as well? I don't really have the time to build out a full blown CMS system in ASP.NET, but if something already exists that can give me X% (25%, 50%, something) of what Joomla has that will at least get me on the right path. Joomla just has too many extensions and too much of a community backing for me to pass it up if there's not something comparable in the ASP.NET realm.

• Generating Dynamic web pages without server side scripting

  - by Microkernel

  Hi guys, I am trying to control a media device which has lot of multimedia content that it can play using another device(remote control device) like an ipad connected to the LAN. (UPnP) I want the media device to be able to send the content listing to the remote device so that it will be rendered as a webpage on the remote controller. And actions on the webpages needs to be sent to the the device as commands to execute (like play, pause, next etc). The media device is an embedded device, hence can't have any server side scripting, all has to be done on the client side. I want the page rendered to be HTML5. So, is it possible to generate dynamic HTML5 pages using just client side scripting? Thanks a lot. I am an embedded systems developer hence clueless about the web designing stuff.

• 3 embedded UIScrollView problem

  - by Infinity

  Hello guys! I have 3 UIScrollView. Here is a sample code, about how they are added in eachother: UIScrollView main; UIScrollView page1; UIScrollView page2; UIScrollView doublePage; UIView pageContent1; UIView pageContent2; UIView doublePageContent; int nrPages = 1; sw2 = 0; main = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0, 0.0, 768, 980)]; main.contentSize = CGSizeMake(768 * (nrPages - 1 + sw2), 980); page1.frame = CGRectMake(0, 0, 768, 980); page2.frame = CGRectMake(768, 0, 768, 980); pageNumber = i - 1 + sw2; (i is a variable in a for loop) doublePage.frame = CGRectMake(768 * (pageNumber - 1), 0, 768 * 2, 980); CGFloat contentWidth = [page1 bounds].size.width + [page2 bounds].size.width; CGFloat contentHeight = page1 ? self.page1.bounds.size.height : self.page2.bounds.size.height; doublePageContent = [[UIView alloc] initWithFrame:CGRectMake(0, 0, contentWidth, contentHeight)]; [page1 addSubview:pageContent1]; [page2 addSubview:pageContent2]; [doublePageContent addSubview:page1]; [doublePageContent addSubview:page2]; [doublePage addSubview:doublePageContent]; [main addSubview:doublepage]; And with this structure the main scrollview don't want to scroll. Without the doublepage scrollview it is working good. What do you think? What's the problem? I know this structure is a little weird, but I need this structure because other parts of the code. Edited, added the information about the sizes. If you need something more please tell me. And one more thing.. If I add 1 pixel to the width of the doublePage contentSize.width it scrolls, but a bit hard, so it scrolls first in the doublePage and then in the main.

• Xcode, Dev Docs Search Field Loosing Focus?

  - by fuzzygoat

  I am having a strange issue with the developer documentation (which i have only noticed after installing Xcode 3.2.3). My problem is that as you type in the search field (upper right) it looses focus and immediately starts looking for the first few letters you type. For example if you looking for "NSObject" you start typing "NSO" and as you type the field looses focus the last 5 characters "bject" just give beeps as you need to reselect the field to type extra characters. Has anyone else come across this or know what the problem might be? cheers Gary.

• Is naming a software product the same as a book legally problematic?

  - by Jake Petroules

  I came up with a name for a software product I'm developing. It's composed of two common English words put together (for example, Firefox, Silverlight, etc.). I Googled the name to see if it was being used by any other software product before committing to it. After finding none, I did notice that there is a book published around 60 years ago, by that same name. Would it be legally problematic to name my software product as such, or does it being a software product vs a book make it irrelevant? PS - I know this isn't really a programming question, but naming is related to software development, isn't it? ;) PPS - How do companies like Microsoft get away with naming things "Windows" and "Office"? Or are they just legally called "Microsoft Windows" and "Microsoft Office"? Do developer names always precede software product names? Would naming a software product "Jones Office" be illegal?

• Do you ever feel confident in your skills?

  - by Gary Willoughby

  As a self taught developer i always find myself questioning my skill and knowledge and always feel like i am falling behind in using new technology. Over a period of nearly 9 years i've studied most mainstream languages (especially C based ones), used lots of different OSes, read and absorbed many books and even written one myself. But i still feel i'm usless! Do professional developers ever get to the stage where they feel confident that they know what they are doing and are confident when submitting solutions/code? When do you know you're good enough?

Thanks!

• What is a class outlet and where is it?

  - by chrish

  I am trying to learn iPhone development and someone passed along the website www.appsamuck.com. On Day 1, the tutorial instructs the developer We need to reference the label in our code so we can update the label * In the document window "File's Owner" * Click: Tools->Idenity Inspector * In the inspector click the + under "Class Outlets" * Change myOutlet1 to "countdownLabel" * Change id to UILabel * Click enter to make sure they commit I really don't want to get hung up on this, but I can't find "Class Outlets" either when creating a new project from scratch or opening the zipped source code project. Is this just a difference in versions of Interface Builder? Where did it go?

• Will VC++ MFC become obsolete in near future?

  - by AKN

  Normally people say MFC is little clumsy. It makes UI development slightly difficult to maintain since it has lot of auto generated code. It has good architecture (doc/view) but is not transparent like Win32 programming to understand how window program works in the background. So with this situation, is it good to extend the exposure on MFC programming or better to switch to .NET since for faster UI design with ease in maintenance. Is it good to continue as MFC developer or good to know .NET as well? How globally companies are looking into MFC as a technology for UI developments. Are they comfortable in supporting their developers to continue with MFC or looking for changing their development technology.
