• 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 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?

• 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?

• Why has extreme programming (XP) gone out of date in favor of Agile, Kanban etc?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 Last 10 years or so, the XP style of working seems to have gone out of date in favor of the working methodologies Agile and/or Kanban.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?

• Proper way to create and work with a subdomain?

  - by Genadinik

  My site got effected by Panda, and I am trying to see if making a subdomain would work. The site is comehike.com, and I created a subdomain which is currently empty at hiking.comehike.com I have a directory /outdoors that has some high quality hand-written articles. I want to put those into the new subdomain to see what would happen. My questions are: Should I just copy and paste the files for those pages into the new subdomain's folder, and just change all the links in all my pages from the original domain to the new subdomain? Should I just do a 301 redirect to the new subdomain? Since test.site.com and www.site.com are different domains, will the new page have to start from scratch in terms of Pagerank, and its rankings in the SERPs?

• 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)?

  It's been a few weeks since I last blogged and, trust me, I am not happy about it :( I have been crazily busy with some of our projects at Tellago which you are going to hear more about in the upcoming weeks :) I was so busy that I didn't even have time to blog about my sessions at Teched US last week.

• 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)

• 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.

• 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.

• Skills to Focus on to land Big 5 Software Engineer Position

  - by Megadeth.Metallica

  Guys, I'm in my penultimate quarter of grad school and have a software engineering internship lined up at a big 5 tech company. I have dabbled a lot recently in Python and am average at Java. I want to prepare myself for coding interviews when I apply for new grad positions at the Big 5 tech companies when I graduate at the end of this year. Since I want to have a good shot at all 5 companies (Amazon,Google,Yahoo,Microsoft and Apple) - Should I focus my time and effort on mastering and improving my Java. Or is my time better spent checking out other languages and tools ( Attracted to RoR, Clojure, Git, C# ) I am planning to spend my spring break implementing all the common algorithms and Data structure out of my algorithms textbook in Java.

• s expression representation for c

  - by wirrbel

  Experimenting with various lisps lately (clojure especially) i have wondered if there are any s expression based representations of (subsets) of c, so you could use lisp/closure to write macros and then convert the s-expression c tree to pure c. I am not asking for a to-c-compilers of lisp/scheme/clojure but more of using lisps to transform a c syntax tree. Little background to why i am asking this question: i find myself to really enjoy certain clojure macros like the threading macros -> doto etc. And i feel that they would be great in a non FP environment as well.

• How are undocumented functions discovered?

  - by Paska

  Hi all, I've always wondered how do you find undocumented / private API ? Example the Apple undocumented / private API, Play Station, Windows Phone 7, Win32 Kernel, Windows API, hidden callback, etc... What tools do hackers use to find out about private and undocumented functions? Where can I read about peoples' experiences delving into private APIs and reverse engineering techniques which reveal the secrets which are normally explained in API documentation? thanks, A

• Why is it good not to rely on changing state?

  - by Slomojo

  This question arises out of the question Is Haskell worth learning? Generally a few often repeated statements are made, about how Haskell improves your coding skills in other languages, and furthermore, this is because Haskell is stateless, and that's a good thing. Why? I've seen someone compare this to only typing with the left hand, or perhaps closing your eyes for a day and just relying on touch. Surely there is more to it than that? Does it relate to hardware memory access, or something else which is a big performance gain?

• practical use of knowledge vs tutorials [on hold]

  - by Lauris Skraucis

  I DONT NEED FACTS,I NEED OPINIONS FROM OTHER DEVELOPERS! Which would be more useful, spend more time on tutorials than on practical use of knowledge or spend more time making real life apps? Like I do everything 50/50 or better I spend all time practicing and putting my knowledge in real life things (php, jQuery, AngularJS)? This is a big pain, I learnt jQuery, then Angular, then php, but didn't practice and forget the code, now I watched basic and intermediate tutorials to refresh knowledge, so what do you think what is the best?

• What is the most compatible, widely used production language to export knowledge and skills gained from Haskell?

  - by World Engineer

  I like Haskell, plain and simple. While Haskell is used in production software, it's not especially widely deployed from what I've seen. What is the most similar and still widely used language in regards to production projects so that I might have a snowball's chance of using something similarly awesome in industry? Also is the same language from the first part available on large numbers of platforms? If not, what is the best alternative that has wide platform deployment? I'd like a single language to put on my to-do list rather than a massive swarm or family. Hard evidence would be a plus.

• why do we need advanced knowledge of mathematics & physics for programming?

  - by Sumeet

  Guys, I have been very good in mathematics and physics in my schools and colleges. Right now I am a programmer. Even in the colleges I have to engrossed my self into computers and programming things all the time. As I used to like it very much. But I have always felt the lack of advanced mathematics and physics in all the work I have done (Programs). Programming never asked me any advanced mathematics and physics knowledge in what I was very good. It always ask u some optimized loops, and different programming technologies which has never been covered in advanced mathematics and physics. Even at the time of selection in big College , such a kind of advanced knowledge is required. Time by time I got out of touch of all that facts and concepts (advanced mathematics and physics). And now after, 5 years in job I found it hard to resolve Differentiations and integrations from Trigonometry. Which sometimes make me feel like I have wasted time in those concepts because they are never used. (At that time I knew that I am going to be a programmer) If one need to be a programmer why do all this advanced knowledge is required. One can go with elementry knowledge a bit more. You never got to think like scientists and R&D person in your Schols and colleges for being a programmer? Just think and let me know your thoughts. I must be wrong somewhere in what I think , but not able to figure that out..? Regards Sumeet
