• How do you get a high paying job programming in finance?

  - by q303

  Hi, I'm interested in eventually programming for a financial company. Unfortunately, I have a degree in linguistics with a minor in CS along with 4 years experience in .NET. I picked .NET because I thought that it would be more used in the financial world. I've heard some horror stories about badly done VBA Excel programming and being way underpaid...but then I've heard great stories about highly skilled C++ programming along with high pay (including some feedback to previous questions). I just get the impression that unless you have a MS in CS from a top 10/20 school, it might not be realistic. For those of you doing programming for bankers/traders, how did you break in?

• How can be data oriented programming applied for GUI system?

  - by Miro

  I've just learned basics of Data oriented programming design, but I'm not very familiar with that yet. I've also read Pitfalls of Object Oriented Programming GCAP 09. It seems that data oriented programming is much better idea for games, than OOP. I'm just creating my own GUI system and it's completely OOP. I'm thinking if is data oriented programming design applicable for structured things like GUI. The main problem I see is that every type widget has different data, so I can hardly group them into arrays. Also every type of widget renders differently so I still need to call virtual functions.

• Why are slower programming languages considered worse than faster ones?

  - by Emanuil

  Here's how I see it. There's machine code and it's all that the computers needs in order to run something. The computers don't care about programming languages. It doesn't matter to them if the machine code comes from Perl, Python or PHP. Programming languages exist to serve programmers. Some programming languages run slower then others but that's not because there is something wrong with them. It's often because they do more things that otherwise programmers would do and by doing these things, they do better what they are supposed to do - serve programmers. So why are slower programming languages considered worse than faster ones?

• What was the first programming language written for computers?

  - by ThePlan

  Looking at so many programming languages we have today, each one being unique in it's own way, I've tried to figure out what the first programming language written for computers is. Looking at the release date for the popular ones I got somewhat close but I didn't look at less obvious ones, programming languages which are either dead or very little use nowadays. Fortran is the closest thing I got but I don't know if it's real. In a nutshell: What was the first programming language written for computers? Are there any languages that derived from that language?

• What syntax element do you hate most in a programming language you use frequently? [closed]

  - by Timwi

  No matter how much you love a programming language, there are always a few details in it that aren’t quite as nice as they could be. In this question, I would like to specifically focus on syntax elements. In a programming language that you use frequently (perhaps your favourite programming language, or perhaps the one you are forced to use at work), which syntax element do you find most unreadable, unclear, inconvenient or unpleasant?

• Why has extreme programming (XP) gone out of date in favor of Agile, Kanban etc?

  - by Nick Rosencrantz

  I like XP (extreme programming) especially the part where there are 2 programmers at the same screen since often a problem's solution gets closer if only you explain what you're doing and pair programming forces you to explain what your doing. Last 10 years or so, the XP style of working seems to have gone out of date in favor of the working methodologies Agile and/or Kanban. Why? Since XP to me seems a veru good way to work and is a lot about the programming where Agile and Kanban are more about processes.

• Is there a canonical book on parallel programming with focus on C++ ?

  - by quant_dev

  I am looking for a good book about parallel programming with focus on C++. Something suitable for a person reasonably good in C++ programming, but with no experience in concurrent software development. On the other hand, I'd prefer a practical book, without loads of silly examples about philosophers eating lunch. Is there a book out there that's the de-facto standard for describing best practices, design methodologies, and other helpful information on parallel programming with focus on C++ ? What about that book makes it special?

• help me understand cuda

  - by scatman

  i am having some troubles understanding threads in NVIDIA gpu architecture with cuda. please could anybody clarify these info: an 8800 gpu has 16 SMs with 8 SPs each. so we have 128 SPs. i was viewing stanford's video presentation and it was saying that every SP is capable of running 96 threads cuncurrently. does this mean that it (SP) can run 96/32=3 warps concurrently? moreover, since every SP can run 96 threads and we have 8 SPs in every SM. does this mean that every SM can run 96*8=768 threads concurrently?? but if every SM can run a single Block at a time, and the maximum number of threads in a block is 512, so what is the purpose of running 768 threads concurrently and have a max of 512 threads? a more general question is:how are blocks,threads,and warps distributed to SMs and SPs? i read that every SM gets a single block to execute at a time and threads in a block is divided into warps (32 threads), and SPs execute warps.

• I'm doing hobby programming; what programming methodologies (e.g. XP, Agile...) do you recommend me to read up on?

  - by Anto

  Most of you would probably just call me a kid (I'm 15). I'm doing hobby programming (I started fiddling around with ActionScript 2.0 in Flash 8 when I was 11, now I do mostly C, Python and Java). As I'm 15, I won't get a job for a long period of time (I'm going to spend years in academia before that) and thus this question is not about which programming methodologies you recommend me to read up on for a software engineering job, but instead which methodologies should a hobby programmer read about? What will a hobby developer learn from reading about your recommendation(s)?

• Hosting StreamInsight applications using WCF

  - by gsusx

  One of the fundamental differentiators of Microsoft's StreamInsight compared to other Complex Event Processing (CEP) technologies is its flexible deployment model. In that sense, a StreamInsight solution can be hosted within an application or as a server component. This duality contrasts with most of the popular CEP frameworks in the current market which are almost exclusively server based. Whether it's undoubtedly that the ability of embedding a CEP engine in your applications opens new possibilities...(read more)

• What are the GPU requirements for XNA 4.0?

  - by Nate Koppenhaver

  I tried to build a sample application using XNA, but I got an error saying that Pixel Shader 1.1 was required, so I got a used Radeon X300 GPU that supports Pixel Shader. I tried to build it again, but I got another error saying that "Your current graphics card does not support the XNA HiDef profile" and would not build. Since that card seems to not be compatible, I guess I need to buy another one. What features should I look for to make sure that it's compatible with XNA?

• Is sticking to one language on a particular project a good practice?

  - by Ans

  I'm developing a pipeline for processing text that will go into production. The question I keep asking myself is: should I stick to one language for the project when I'm looking for a tool to do a particular task (e.g. NLTK, PDFMiner, CLD, CRFsuite, etc.)? Or is it OK to mix and match languages on the project? So I pick the best tool regardless of what language it's written in (e.g. OpenNLP, ParsCit, poppler, CFR++, etc.) and warp (wrap) my code around it? Note, I am not asking about should a developer stick to just one language for their career.

• Am I copy/paste programmer ?

  - by Searock

  When ever I am stuck with a particular problem, I search for a solution in Google. And then I try to understand the code and tweak it according to my requirement. For example recently I had asked a question Reading xml document in firefox in stack overflow. Soufiane Hassou gave me a link to w3schools, where I found a example on parsing xml document, I understood how the example works, but I copied the code and tweaked it according to my requirement, since I don't like typing much. So does this make me a copy/paste programmer? How do you say if a person is a copy/paste programmer ? Thanks.

• Are there any memorization techniques that exist for programmers? [closed]

  - by Akromyk

  I just watched this video on Ted.com entitled: Joshua Foer: Feats of memory anyone can do and it got me thinking about memory from a programmers perspective. There are so many abstract concepts and syntactic nuances we encounter daily, and yet we still manage to remember enough information to be productive. The memory palace may help in remembering someone's name or a random story but are there any memorization techniques that can better aid programmers?

• What's the best algorithm for... [closed]

  - by Paska

  Hi programmers! Today come out a little problem. I have an array of coordinates (latitude and longitude) maded in this way: [0] = "45.01234,9.12345" [1] = "46.11111,9.12345" [2] = "47.22222,9.98765" [...] etc In a loop, convert these coordinates in meters (UTM northing / UTM easting) and after that i convert these coords in pixel (X / Y) on screen (the output device is an iphone) to draw a route line on a custom map. [0] = "512335.00000,502333.666666" [...] etc The returning pixel are passed to a method that draw a line on screen (simulating a route calculation). [0] = "20,30" [1] = "21,31" [2] = "25,40" [...] etc As coordinate (lat/lon) are too many, i need to truncate lat/lon array eliminating the values that doesn't fill in the map bound (the visible part of map on screen). Map bounds are 2 couple of coords lat/lon, upper left and lower right. Now, what is the best way to loop on this array (NOT SORTED) and check if a value is or not in bound and after remove the value that is outside? To return a clean array that contains only the coords visible on screen? Note: the coords array is a very big array. 4000/5000 couple of items. This is a method that should be looped every drag or zoom. Anyone have an idea to optimize search and controls in this array? many thanks, A

• How can I make the camera return to the beginning of the terrain when it reaches the end?

  - by wbaccari

  How can I make the camera return to the beginning of the terrain when it reaches the end? I tried using the ICameraSceneNode*-setPosition(). if (camera->getPosition().X>1200.f) camera->setPosition(vector3df(1.f,1550.f,camera->getPosition().Z)); if (camera->getPosition().X<0.f) camera->setPosition(vector3df(1199.f,1550.f,camera->getPosition().Z)); if (camera->getPosition().Z>1200.f) camera->setPosition(vector3df(camera->getPosition().X,1550.f,1.f)); if (camera->getPosition().Z<0.f) camera->setPosition(vector3df(camera->getPosition().X,1550.f,1199.f)); It seems to work fine with a flat terrain (one shade of grey in heightmap) but it starts to produce a strange behavior as soon as i try to add some hills. Edit: The setPosition() call seems to perform a translation of the camera toward the new position, therefore the camera stops at the first obstacle it encounters on its way.

• vgaswitcheroo - switch GPU based on load?

  - by Primož Kralj

  Is it possible to make vgaswitcheroo switch between GPU based on load? For example, when computer would be in idle it would turn off discrete and use only integrated; when enough load would accumulate on it it would automatically turn on discrete graphics and disable integrated. My second question is whether there is any GUI applet or something that I could use to manually switch between GPUs - instead of manually echoing in switch file? Edit: I found answer to last question at https://help.ubuntu.com/community/HybridGraphics

• How to write functionally in a web framework

  - by Kevin Burke

  I love Rich Hickey, Clojure and Haskell and I get it when he talks about functions and the unreliability of side-effecting code. However I work in an environment where nearly all the functions I write have to read from the database, write to the database, make HTTP requests, decrement a user's balance, modify a frontend HTML component based on a click action, return different results based on the URI or the POST body. We also use PHP for the frontend, which is littered with functions like parse_str(), which modifies an object in place. All of these are side-effecting to one degree or another. Given these constraints and the side-effecting nature of the logic I'm coding, what can I do to make my code more reliable and function-able?

• Starting all over again?

  - by kyndigs

  Have you ever been developing something and just came to a point where you think that this is rubbish, the design is bad and although I will lose time it will be better to just start all over again? What should you consider before making this step? I know it can be drastic in some cases, is it best to just totally ignore what you did before, or take some of the best bits from it? Some real life examples would be great.
