• Can I develop games for mobile platforms in C++?

  - by James Bern

  I have a good grasp in C++ and C and have also experience developing AAA game using C++. Now, I'm shamelessly thinking to dive into mobile game development either in iOS or Android. Unfortunately, I don't know objective-C and java and neither have courage to learn it. So, As above mentioned reason, Is there any possibility to do mobile development in C++ without using any single statement of JAVA and Objective-C ?

• What can I do with urllib?

  - by Aerovistae

  I grasp that it can fetch internet resources, but I'm not really fully appreciating what that means. I was doing the challenges at pythonchallenge.com, and I got past the one that requires urllib to fetch the page and read the source, but I don't see how this is useful quite yet. And examples are kind of lacking in diversity. What else can it do, or how can I use this to my advantage? (Besides building a web browser...)

• Do you prefer building your interfaces in IB or programmatically? and why?

  - by LolaRun

  I've been using Xcode and building iPhone apps for two months, but I'm finding it really hard to grasp good application design. I always face problems—like you can't put your tabbarcontroller in another custom viewcontroller, for example—that 'sometimes', of course, would work if you did the creation of the views/viewcontrollers programmatically. So I don't know if I should start writing the creation of my objects or use Interface Builder. What are your experiences?

• Concept of bit fields

  - by user1369975

  Whenever I read a code like this: struct node { int x : 2; int p : 4; }n; with bit fields involved, I get really confused, as to how they are represented in memory, what is sizeof(n) etc., how does it differ with normal members of structures? I tried referring K&R and http://en.wikipedia.org/wiki/Bit_field but they little to remove my confusion. What concepts of bit fields am I failing to grasp?

• Help a C# developer understand: What is a monad?

  - by Charlie Flowers

  There is a lot of talk about monads these days. I have read a few articles / blog posts, but I can't go far enough with their examples to fully grasp the concept. The reason is that monads are a functional language concept, and thus the examples are in languages I haven't worked with (since I haven't used a functional language in depth). I can't grasp the syntax deeply enough to follow the articles fully ... but I can tell there's something worth understanding there. However, I know C# pretty well, including lambda expressions and other functional features. I know C# only has a subset of functional features, and so maybe monads can't be expressed in C#. However, surely it is possible to convey the concept? At least I hope so. Maybe you can present a C# example as a foundation, and then describe what a C# developer would wish he could do from there but can't because the language lacks functional programming features. This would be fantastic, because it would convey the intent and benefits of monads. So here's my question: What is the best explanation you can give of monads to a C# 3 developer? Thanks! (EDIT: By the way, I know there are at least 3 "what is a monad" questions already on SO. However, I face the same problem with them ... so this question is needed imo, because of the C#-developer focus. Thanks.)

• Recursion in assembly?

  - by Davis

  I'm trying to get a better grasp of assembly, and I am a little confused about how to recursively call functions when I have to deal with registers, popping/pushing, etc. I am embedding x86 assembly in C++. Here I am trying to make a method which given an array of integers will build a linked list containing these integers in the order they appear in the array. I am doing this by calling a recursive function: insertElem (struct elem *head, struct elem *newElem, int data) -head: head of the list -data: the number that will be inserted at the end of a list -newElem: points to the location in memory where I will store the new element (data field) My problem is that I keep overwriting the registers instead of a typical linked list. For example, if I give it an array {2,3,1,8,3,9} my linked-list will return the first element (head) and only the last element, because the elements keep overwriting each other after head is no longer null. So here my linked list looks something like: 2--9 instead of 2--3--1--8--3--9 I feel like I don't have a grasp on how to organize and handle the registers. newElem is in EBX and just keeps getting rewritten. Thanks in advance!

• Relative security of SAML vs Kerberos

  - by Robert Gowland

  Does anyone have any info/links on the relative security of SAML vs Kerberos. I believe I grasp the differences between the two, and what they mean for my particular application, but to decided between the two, knowing which is more secure, if either, would be a valuable bit of info.

• Difference ProxyPass and RewriteRule

  - by Wesho

  I just came across a case where ProxyPass (ProxyPassMatch to be exact) is being used in an Apache configuration file. This mod_proxy rule is being used to proxy from a whole cluster to one specific server, when a certain file is requested which only resides on that server. Now I'm a bit confused since I can't grasp why something like this cannot be achieved using a RewriteRule. So in essence I want to ask: What is the difference between ProxyPassMatch and a RewriteRule in this case?

• What is SIP trunking?

  - by hypnocode

  Can someone explain to me in plain English what SIP trunking is, please? I've read about it on Google, but I don't really grasp it yet. Does it allow a VoIP call to be placed outside of the LAN? So if you had Asterisk setup as the PBX, then IP calls could be made outside of the network? Am I close or am I just saying stupid words?

• How much traffic is high-traffic [closed]

  - by Jack

  My primary interest is in gathering information about the technology used behind public facing websites. Much of the information I read arbitrarily differentiates between high-traffic vs the unstated non-high-traffic websites. This troubles me because I don't have a good grasp of how much traffic is high-traffic. Can anyone help me with this, is there a good rule of thumb? Please don't tell me it depends ;)

• Ruby on Rails - How can I start? [closed]

  - by Mashael

  I have misconception in understanding the relationship between Ruby language and Ruby on Rails Framework. Because of 'I am an absolute beginner' in web development I have no idea if I have to grasp the fundamentals of Ruby before I go with Ruby on Rails! I also want to ask who is behind both Ruby and Ruby on Rails. Who is developing both? And is there intention to improve its speed? In short, I'd like to know the road map to effectively beginning learning Ruby on Rails. Furthermore, I'm wondering about the next steps in improving Ruby and Rails and who are the main role players in improving them?

• What's a nice explanation for recursion?

  - by Gulshan

  This question is inspired by What's a nice explanation for pointers? So, what can be a nice explanation of the recursion? Update: The idea of recursion is not very common in real world. So, it seems a bit confusing to the novice programmers. Though, I guess, they become used to the concept gradually. So, what can be a nice explanation for them to grasp the idea easily? I expected some detailed answers. N.B. : Even I am going to post one answer. But to be fair, it will be few hours later.

• visual basic coach needed [closed]

  - by Danny

  0 down vote favorite I am trying to learn visual basic. I used to program in gw-basic and have trouble learning vb.net by reading and googling all the time. It takes so much time to find the answers to my programming problems and even then i do not understand the why it have to be done that way. I have beginners questions like finding childwindows using enumwindow. Then googling for hours and hours i do not seem to grasp it (must be my old age). I would like to get someone i could learn from by asking questions about what i want to program and learn from it. not to just finish the program but to learn and understand it too. Someone who dont find questions stupid to ask as i try to build my understanding of the visual basic environment. I hope to communicate by using skype voice or chat or other direct means when time permits it. Cheers, Danny

• What are the most important OO skills to show off in the job hunt?

  - by Kat

  I am in the market for new employment, and found a position were they asked me to create a programming sample based off an assignment. I blew the sample trying to get it done quickly one night, and got declined - only to be given a second chance recently. The concern was that I didn't really demonstrate object oriented knowledge. I've rethought my approach but I figure it's worth asking: if you were hiring someone for an OO position, what skills would you most want to see them demonstrate they had a firm grasp on? I want to be sure that I'm missing anything important this time around.

• To maximize chances of functional programming employment

  - by Rob Agar

  Given that the future of programming is functional, at some point in the nearish future I want to be paid to code in a functional language, preferably Haskell. Assuming I have a firm grasp of the language, plus all the basic programmer attributes (good communication skills/sense of humour/hygiene etc), what should I concentrate on learning to maximize my chances? Are there any particularly sought after libraries I should know? Alternatively, would another language be a better bet, say F#? (I'm not too fussed about the kind of programming work, so long as it's reasonably interesting and reasonably well paid, and with nice people)

• Live from ODTUG - Big Data and SQL session #2

  - by Jean-Pierre Dijcks

  Sitting in Dominic Delmolino's session at ODTUG (KScope 12). If the session count at conferences is any indication then we will see more and more people start to deploy MapReduce in the database. And yes, that would be with SQL and PL/SQL first and foremost. Both Dominic and our own Bryn Llewellyn are doing MapReduce in the database presentations.  Since I have seen both, I would advice people to first look through Dominic's session to get a good grasp on what mappers do and what reducers do, then dive into Bryn's for a bunch of PL/SQL example. The thing I like about Dominic's is the last slide (a recursive WITH statement) to do this in SQL... Now I am hoping that next year we will see tools vendors show off how they work with Hadoop and MapReduce (at least talking about the concepts!!).
