• unique selling points: php, flash, rails

  - by pwebdev

  on reflecting how to talk with prospect customers on technologies for web applications, what are important requirements for chosing a specific technology? I am biased towards ruby on rails, but the code base and community of PHP is larger, while the user experience of flash sites is often an advantage to the segment of higher paying customers. how would you argue for or against the usage of a technology in general? for ruby on rails in particular?

• Is there a C# equivalent of typeof for properties/methods/members?

  - by David

  A classes Type metadata can be obtained in several ways. Two of them are: var typeInfo = Type.GetType("MyClass") and var typeInfo = typeof(MyClass) The advantage of the second way is that typos will be caught by the compiler, and the IDE can understand what I'm talking about (allowing features like refactoring to work without silently breaking the code) Does there exist an equivalent way of strongly referencing members/properties/methods for metadata and reflection? Can I replace: var propertyInfo = typeof(MyClass).GetProperty("MyProperty") with something like: var propertyInfo = property(MyClass.MyProperty)

• Which version of .NET is available for Xbox 360?

  - by Rosarch

  I tried to look this up on MSDN, but couldn't get a straight answer. It says: The .NET Compact Framework for Xbox 360 implements a subset of the .NET Compact Framework, and has been optimized to take advantage of and expose the power of the Xbox 360. What exactly is the subset? Which version of the framework? 3.5? 2.0?

• Using low level api for datastore in google app engine ? is it bad ?

  - by Chez

  There is little documentation on how to use the low level api for datastore and quite a lot on JPA and JDO and how it translates to it. My question is: is there any advantage in coding against the JPA or JDO specs instead of accessing directly the low level api for datastore ? From an initial look, it seems simple and straight forward but I am not sure if there are good reasons why not to do it. Thanks Cx

• Remote Desktop in Linux like Team Viewer

  - by crissangel

  For Remote Desktop Sessions in Linux, I want to know if there something available equivalent for what Team Viewer does for windows? The main advantage I find of Team viewer is that it can bypass firewalls, needs no NAT configurations or port forwarding rules to be setup in the router.

• In an iPhone app, is it beneficial to tile a background image that has a pattern in it?

  - by Dr Dork

  Here's an example of the type of background image I'm talking about, the iPhone Notes app... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

• generate PHP classes from XSD?

  - by Qwerty

  Is there in the world analogues of JavaBeans or JAXB for PHP? Is it possible to generate PHP classes from XML schema? It's common practice to publish API's as XSD schemas. Java and C# guys can get advantage of this by generating classes right from XSD. Is there same tool for PHP?

• Script-Based Configuration in .net?

  - by Michael Stum

  One of the downsides of web.config/app.config is that it's just Magic Strings everywhere, since it's just an XML file. Interpreted languages like PHP or Ruby have the advantage that the configuration is just code that is executed. In .net, doing stuff in code requires a redeployment, which defeats the purpose. Now, before I build my own web.config replacement based on Boo or PowerShell I wanted to know if there is an existing one?

  - by Amitabh

  I was just looking into the source code of an existing project which uses nHibernate and found that there are interfaces created for each entity classes. E.g ICustomer for Customer class.

• What's a good place to learn differences between MVC 1.0 and MVC 2.0?

  - by Jay Stevens

  I have a small project I started in MVC 1 and have resisted (until now) moving to MVC 2. Problem is, everything seems to be just a mishmash of MVC. So... What significant differences are there? What do I need to know to take advantage of what's there? Are there breaking changes? Where's a good place to learn all of this stuff?

• returning aligned memory with new?

  - by Steve

  I currently allocate my memory for arrays using the MS specific mm_malloc. I align the memory, as I'm doing some heavy duty math and the vectorization takes advantage of the alignment. I was wondering if anyone knows how to overload the new operator to do the same thing, as I feel dirty malloc'ing everywhere (and would eventually like to also compile on Linux)? Thanks for any help

• Is it a bad programming practise to have "Public" members inside an "Internal" class?

  - by Amby

  I mean, won;t it be more specific and appropriate if i "only" keep "protected","internal" and "private" members (field,method,property,event) in a class which is declared as "internal" ? I have seen this practice ( having "public" members in an "internal" class) in various code so just wanted to know is it a bad practice or does it has some benefit or advantage. [Only concerned about C#] Thanks for your interest.

• Which to learn first: Java/J2EE or .NET ?

  - by Eric Gustavson

  Is there an advantage to learning Java or .NET first? (ie. would the transition from J2EE to .NET be significantly easier than the reverse?) Do you think that one platform has overtaken the other in terms of industry use? (feel free to be as biased or as objective as you like) see also: Java or .NET?

• Can RAM handle different data type sizes?

  - by tstbu

  int, char and bool usually have different sizes. Where intcharbool, I suppose. But does the RAM even support this? How is it built up? Can it take advantage of bool being only 1 byte and store it in a small "register"?

• CSS: a:link vs just a (without the :link part)

  - by Rob

  So we're required to use the following order for CSS anchor pseudo-classes a:link { color: red } a:visited { color: blue } a:hover { color: yellow } a:active { color: lime } But my question is why bother with the a:link part? Rather, is there any advantage to the above (other than perhaps clarity) over: a { color:red; } /* notice no :link part */ a:visited { color: blue; } etc.,etc.

• Click to select from a list of tags in jQuery

  - by Michael Doornbos

  I'm struggling to find a tag selection UI for a rails app. Ideally it would be something like the selection here on Stackoverflow, or on Delicious or Digg. I want users to be able to select multiple tags with a single click. We're already using jQuery, so it makes sense to use something that takes advantage of that. I've used the selection ui in jQuery and I'm not thrilled about having users need to hold down ctrl to select multiple tags.

  - by Gilbo

  From what I understand the data will be "persisted" (physically stored, not just retrieved when i need it). Is this correct? If so what would be the advantage of using an indexed view versus just using a table?

• Should i use a C function or Obj-C Method?

  - by Daniel Granger

  I'm about to create a function which adds to NSDateComponents together is there any advantage to putting this in a C style function or should it go in a Obj-C method? Is there ever a reason to use one rather then the other or should I always stick to Obj-C? BTW: Not that it makes any difference I'm sure but this is for an app on the iPhone Many thanks
