• How can a web developer learn to develop for the iPhone?

  - by Jared Christensen

  I'm a web developer and I'm getting envious of all the cool iPhone apps. I know nothing about C or what ever language they use to make iPhone apps. I really have no idea where to start. What do I need to do? Should I take a class, buy a book? I have a pretty good grasp on programing, I do tons of HTML, CSS and Javascript development and some PHP and Action Scripting. I'm not very good with Object Oriented Programing but I think I could pick it up if I used it more. I love video tutorials like lynda.com or net.tutsplus.com. I learn best buy jumping in and getting my hands dirty.

• C++ domain specific embedded language operators

  - by aaa

  hi. In numerical oriented languages (Matlab, Fortran) range operator and semantics is very handy when working with multidimensional data. For example: A(i:j,k,:n) // represents two-dimensional slice B(i:j,0:n) of A at index k unfortunately C++ does not have range operator (:). of course it can be emulated using range/slice functor, but semantics is less clean than Matlab. I am prototyping matrix/tensor domain language in C++ and am wondering if there any options to reproduce range operator. I still would like to rely on C++/prprocessor framework exclusively. So far I have looked through boost wave which might be an suitable option. is there any other means to introduce new operators to C++ DSL?

• How should my team decide between 3-tier and 2-tier architectures?

  - by j0rd4n

  My team is discussing the future direction we take our projects. Half the team believes in a pure 3-tier architecture while the other half favors a 2-tier architecture. Project Assumptions: Enterprise business applications Business logic needed between user and database Data validation necessary Service-oriented (prefer RESTful services) Multi-year maintenance plan Support hundreds of users 3-tier Team Favors: Persistant layer <== Domain layer <== UI layer Service boundary between at least persistant layer and domain layer. Domain layer might have service boundary between it. Translations between each layer (clean DTO separation) Hand roll persistance unless we can find creative yet elegant automation 2-tier Team Favors: Entity Framework + WCF Data Service layer <== UI layer Business logic kept in WCF Data Service interceptors Minimal translation between layers - favor faster coding So that's the high-level argument. What considerations should we take into account? What experiences have you had with either approach?

• Why are the interpreters of all popular scripting languages written in C (if not in C at least not i

  - by wndsr

  I recently asked a question on switching from C++ to C for writing an interpreter for speed and I got a comment from someone asking why on earth I would switch to C for that. So I found out that I actually don't know why - except that C++ object oriented system has a much higher abstraction and therefore is slower. Why are the interpreters of all popular scripting languages written in C and not in C++? If you want to tell me about some other language where the interpreter for it isn't in C, please replace all occurences of popular scripting languages in this question with Ruby, Python, Perl and PHP.

• In .NET which loop runs faster for or foreach

  - by Binoj Antony

  In c#/VB.NET/.NET which loop runs faster for or foreach? Ever since I read that for loop works faster than foreach a long time ago I assumed it stood true for all collections, generic collection all arrays etc. I scoured google and found few articles but most of them are inconclusive (read comments on the articles) and open ended. What would be ideal is to have each scenarios listed and the best solution for the same e.g: (just example of how it should be) for iterating an array of 1000+ strings - for is better than foreach for iterating over IList (non generic) strings - foreach is better than for Few references found on the web for the same: Original grand old article by Emmanuel Schanzer CodeProject FOREACH Vs. FOR Blog - To foreach or not to foreach that is the question asp.net forum - NET 1.1 C# for vs foreach [Edit] Apart from the readability aspect of it I am really interested in facts and figures, there are applications where the last mile of performance optimization squeezed do matter.

• Mocking my custom dependencies with Spring

  - by Brabster

  Is is possible to declare mocks using some mocking framework for my own classes declaratively with Spring? I know there are some standard mocks available in Spring, but I'd like to be able to mock out my own classes declaratively too. Just to check I'm not going about this the wrong way: the idea is to have a pair of JUnit test and Spring config for each integration test I want to do, mocking everything except the specific integration aspect I'm testing (say I had a dependency on two different data services, test one at a time) and minimising the amount of repeated Java code specifying the mocks.

• How do you manage your time as a team leader?

  - by Bryan Slatner

  Where I work, my role has been evolving from a pure development role to team leadership. I find that this suits me, and I'm generally enjoying it. One aspect of the job that continually vexes me, though, is time management. My day used to be pure coding. Now, I still have a largely full plate of coding duties, but I'm expected to mentor other developers, work on requirements, make design decisions for other developers, evaluate bug reports from users, assign them to developers, and so on. I find that my day has become on interruption after another and the prolonged periods of sustained concentration needed to get any actual quality coding done are becoming rarer and rarer. Today, I finally grabbed my laptop and escaped to a coffee shop so I could get some actual work done. How do the team leads here manage their day -- or manage their workplace -- so they don't let their administrative tasks overwhelm them?

• Why do most Database developers hate Agile

  - by Calm Storm

  To me "Agile" methodology is a common-sense oriented approach and one that should likely be adopted for most software projects. I find that while a lot of Middle Tier Developers and Front End developers find it a very sensible project delivery model, plenty of Database developers (and good ones) seem to be totally against it. They are very keen on knowing the biggest picture and designing a database solution that will cater to that. They do not seem to like "Vertical striping" of a functionality. They would rather see the complete design document/feature document instead of concentrating on small user stories. Sarcasm aside, can someone realistically provide some insight as to why this mentality is prevalent? Especially DB devs? What would be a convincing argument against that?

• Javascript clarity of purpose

  - by JesDaw

  Javascript usage has gotten remarkably more sophisticated and powerful in the past five years. One aspect of this sort of functional programming I struggle with, esp with Javascript’s peculiarities, is how to make clear either through comments or code just what is happening. Often this sort of code takes a while to decipher, even if you understand the prototypal, first-class functional Javascript way. Any thoughts or techniques for making perfectly clear what your code does and how in Javascript? I've asked this question elsewhere, but haven't gotten much response.

• OO C++ - Virtual Methods

  - by Phorce

  Just a really quick question here. I'm using virtual functions to read in from a text file. Now, it's virtual because in one aspect I want the values to be normalised, and, in the other respect I don't want them to be normalised. I have tried to do this: bool readwav(string theFile, 'native'); So in theory, if the 'native' is used, this method should be called, however, if 'double' is called then a different version of the method is called. Same for if the value is empty, it should just perform the native option. First question, why doesn't the declaration above work? Also, is this the best route to go down? Or, would it be better to have just one class method that switches between the options. Thanks :)

• Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

  - by user193655

  If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

• ORM on iPhone. More simple than CoreData.

  - by Alexander Babaev

  The question is rather simple. I know that there is SQLite. There is Core Data also. But I need something in between. More object-oriented than SQLite API and simplier than Core Data. Main points are: I need access to stored entities only by id. No queries required. I need to store items of a single type, it means that I can use only one table if I choose SQLite. I want automatic object-relational conversion. Or object-storage if the storage is not relational. I can use object archiving, but I have to implement things (NSArchiver). But I want to write some kind of class and get persistence automatically. As it can be done with Hibernate/ActiveRecord/Core Data/etc. Thanks.

• Image size in DB?

  - by user1104916

  I made an application that store Item pictures (jpeg) in SQL Server DB, the use shot pictures with his camera (file size ~ 2 M), in my aaplication I check if picture.Width 800 or picture.Height 600, I resize the picture to 800x600. -- if I export picture from DB, the file size is about 100k, if I open the same picture in photoshop, the image size shows 1.37M. 01-- I want to know the space that takes this picture in my DB. The reason I'm resizing the picture before storing it in my DB, is that I imagine it take a huge space in my DB. 02-- How to resize a picture to keep it' s aspect ratio?

• Why "constructor-way" of declaring variable in "for-loop" allowed but in "if-statement" not allowed?

  - by PiotrNycz

  Consider this simple example: /*1*/ int main() { /*2*/ for (int i(7); i;){break;} /*3*/ if (int i(7)) {} /*4*/ } Why line-2 compiles just fine, whilst line-3 gives the error? This is little strange to me why if-statement is in this aspect treated worse than for-loop? If this is compiler specific - I tested with gcc-4.5.1: prog.cpp: In function 'int main()': prog.cpp:3:7: error: expected primary-expression before 'int' prog.cpp:3:7: error: expected ')' before 'int' I was inspired by this question [UPDATE] I know this compiles just fine: /*1*/ int main() { /*2*/ for (int i = 7; i;){break;} /*3*/ if (int i = 7) {} /*4*/ }

• php quick form creation

  - by Akshey

  Hi, I have been using php from some time and I have noticed that it takes a long time to create a form with validation using php. Are there any scripts or IDE wizards which can assist a programmer to create php forms quickly and also give the programmer flexibility to customize the form easily? I found some webservices which provide such services but they are mostly oriented towards non-programmers and the forms they generate are not easily customizable and do not support all kinds of functionalities. Infact, most of them are meant for generating contact forms. Regards, Akshey

• matlab: putting a circled number onto a graph

  - by Jason S

  I want to put a circled number on a graph as a marker near (but not on) a point. Sounds easy, but I also want to be invariant of zoom/aspect ratio changes. Because of this invariant, I can't draw a circle as a line object (without redrawing it upon rescale); if I use a circle marker, I'd have to adjust its offset upon rescale. The simplest approach I can think of is to use the Unicode or Wingdings characters ① ② ③ etc. in a string for the text() function. But unicode doesn't seem to work right, and the following sample only works with ① and not for the other numbers (which yield rectangle boxes): works: clf; text(0.5,0.5,char(129),'FontName','WingDings') doesn't work (should be a circled 2): clf; text(0.5,0.5,char(130),'FontName','WingDings') What gives, and can anyone suggest a workaround?

• MVC & Design patterns in C++

  - by theunanonim

  I have an assignment (university level) in C++ The application that was done so far: - MVC agenda - the views are command-line - Agenda contains a list of contacts - a contact may be a friend or an acquiantance - Agenda may contain also a Company that is a contact and may contain other contacts (sorry the code is already too big as I tried to keep the MVC aspect of the application, and I can't post it here or request your time to study it..) To do: - implement factory method pattern - implement observer pattern - implement strategy pattern - implement visitor pattern The evaluation will depend on the number of added patterns and places they have been added. Am I an idiot or this is the stupidies possible assignement ? If not, please help me with some basic tips.. which one where ? Best Regards. P.S. Sorry for my English

• Mapping tables from an existing database to an object -- is Hibernate suited?

  - by Bernhard V

  Hello! I've got some tables in an existing database and I want to map them to a Java object. Actually it's one table that contains the main information an some other tables that reference to such a table entry with a foreign key. I don't want to store objects in the database, I only want to read from it. The program should not be allowed to apply any changes to the underlying database. Currently I read from the database with 5 JDBC sql queries and set the results then on an object. I'm now looking for a less code intensive way. Another goal is the learning aspect. Is Hibernate suitable for this task, or is there another ORM framework that better fits my requirement?

• How many months of fixing somebody else's bugs would you endure?

  - by Hamish Grubijan

  I understand that fixing bugs is a way to learn the system for the new people. But what if the system is so large that you can fix other people's bugs for 2 years and still not learn about every aspect of it? I would imagine that most people would get bored and not give their 100% to fixing bugs caused by others. Is there something wrong with the process? Everybody is chanting "Scrum! Scrum!" and getting certified, but that is just another phrase to me. How do you get noticed if all you do is fix bugs? Stand by a water-cooler perhaps and brag about how cool my bug fixes are? My political beliefs seem to be opposite from everybody else's at the company, and I have zero interest in pop culture/trivia/Tiger Woods scandals - there goes my opportunity to socialize during a lunch hour.

• Obtain all keys of a Neo4j index

  - by MattiSG

  I have a Neo4j database whose content is generated dynamically from a big dataset. All “entry points” nodes are indexed on a named index (IndexManager.forNodes(…)). I can therefore look up a particular “entry point” node. However, I would now like to enumerate all those specific nodes, but I can't know on which key they were indexed. Is there any way to enumerate all keys of a Neo4j Index? If not, what would be the best way to store those keys, a data type that is eminently non-graph-oriented? UPDATE (thanks for asking details :) ): the list would be more than 2 million entries. The main use case would be to never update it after an initialization step, but other use cases might need it, so it has to be somewhat scalable. Also, I would really prefer avoiding killing my current resilience abilities, so storing all keys at once, as opposed to adding them incrementally, would be a last-resort solution.

• Suggested C++ books?

  - by Josh Bradley

  Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

• Javascript/jQuery: Varying parameters on a custom function

  - by dclowd9901

  I'm writing a plugin that will allow parameters to 'set it up.' But I predict the user won't always want to set up every aspect of the function. function This_Function(a,b,c,d); For instance, maybe they'll only want to set up a and c, but not b and d (they'll just prefer to leave those as defaults). How do I write the function (or the parameters for that matter) so that the user can customize which functions they would prefer to pass? I have a feeling it involves parsing input, but I've seen many other functions with this capability. Thanks in advance for the help.

• Class works without declaring variables?

  I'm learned php as functional and procedure language. Right now try to start learn objective-oriented and got an important question. I have code: class car { function set_car($model) { $this->model = $model; } function check_model() { if($this->model == "Mercedes") echo "Good car"; } } $mycar = new car; $mycar->set_car("Mercedes"); echo $mycar->check_model(); Why it does work without declaration of $model? var $model; in the begin? Because in php works "auto-declaration" for any variables? I'm stuck

• jCarousel Lite - center images horizontally and vertically

  - by carillonator

  I have jCarousel Lite going in Drupal with images of various sizes/aspect ratios. I'm not having much luck trying to center the images vertically and horizontally (i.e. evenly-spaced). The plugin requires that the images be in a <ul><li><img ... /></li></ul>. I've tried display:inline-block, marginTop:50% among other things, most of which just screw up the carousel. The carousel is posted at: http://carillontech.org/drupal/ thanks!!

• Does anybody have practice in programming PCMEF - architectures?

  - by Erkki

  PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?
