• Useful programming languages for hardware programming

  - by Sebastian Griotberg

  I am thinking to take the next semester a course called "Digital systems architecture", and I know that we need to program micro-controllers with several programming languages such as C, C++, verilog, and VHDL. I want to be prepared to take that course, but I need to know if I need to study deeper these languages. At this moment, I have taken one course in basic Java dealing with basic methods, data types, loop structures, vectors, matrices, and GUI programing. Must I study deeper Java and then go with C, and C++? Besides, I know basic verilog and VHDL.

• Interviews that include Algorithms and Data Structures

  - by EricFromSouthPark

  I want to start looking for jobs in great companies and I have four years of enterprise corporations development, three years with C#.NET and alomst one year with Ruby On Rails, JS, etc... But when I look up interview questions from Google, Amazon, Fog Creek, DropBox, etc... they are really targeted at students that are coming fresh out of college and still remember what was Dynamic Programming and Dijkstra algorithms ... but I don't! :( It has been a while for me ... If a I need a sort algorithm I would either Google it or there already is a library and method that does it for me. So what should I do? Do they realize that this guy is not coming from college and will ask more general questions about software architecture or nop! I should go back find my old Data structures book from the storage and read them? In that case wht books and language do you recommend to hone my skills?

• How to prepare for the GRE Computer Science Subject Test?

  - by Maddy.Shik

  How do I prepare for the GRE Computer Science subject test? Are there any standard text books I should follow? I want to score as competitively as possible. What are some good references? Is there anything that top schools like CMU, MIT, and Standford would expect? For example, Cormen et al is considered very good for algorithms. Please tell me standard text books for each subject covered by the test, like Computer Architecture, Database Design, Operating Systems, Discrete Maths etc.

• Logic in Entity Components Sytems

  - by aaron

  I'm making a game that uses an Entity/Component architecture basically a port of Artemis's framework to c++,the problem arises when I try to make a PlayerControllerComponent, my original idea was this. class PlayerControllerComponent: Component { public: virtual void update() = 0; }; class FpsPlayerControllerComponent: PlayerControllerComponent { public: void update() { //handle input } }; and have a system that updates PlayerControllerComponents, but I found out that the artemis framework does not look at sub-classes the way I thought it would. So all in all my question here is should I make the framework aware of subclasses or should I add a new Component like object that is used for logic.

• Massive vehicular network simulator

  - by IvanK

  I am interested in making a vehicular network simulator (vehicular network as in vehicles can be equipped with radios and when they come in range they can talk with each other). I want to be able to scale to 1000s of nodes if not more. I am quite frankly torn on how to do, or even which language to use or whether I should instead be using some other piece of software/code. I know that this should depend on a lot of design decisions that I may have, but it would be great if somebody can point me towards the right direction. I was planning to use a multi-threaded architecture, but not sure whether it will add to the complication or make it easier. Also if I go for a multi-threaded architecutre, do you think that 'Go' language will be a good choice?

• Is it normal to sometimes take a while to get even basic things working in software development?

  - by user1092719

  This is a little hard to explain because it's a really generic question, but bear with me... I find that when I am doing or recreating basic things from scratch (i.e. without the help of libraries), sometimes it feels as though I'm taking much more time to do the task than is actually needed. I am not new to programming or development & design concepts and have worked extensively with around 9 languages and various platforms and paradigms over 5/6 years. Although I don't yet have any academic qualification for programming and have learned almost exclusively from the Internet, I have been told that the quality of my code is excellent by those with qualifications. So, I don't think I'm a bad programmer because I really love doing it and working with software architecture, but maybe I'm slow? Or is it normal to take sometimes longer than it seems necessary to do basic tasks?

• Alternating links and slide down content on a list of sub sections

  - by user27291

  I have a page for a doctor's practice. In the summary page for the practice there is a list of subsections such as Women's, Men's, Children, Sport, etc. Some of these sub sections are very large, others can be a paragraph or more with a short unordered list. In terms of content volume, the large subsections warrant their own separate page, the smaller one's not so much. I created a little plugin which enables me to use the list of subsections in 2 ways. When clicking on the title of a larger section, you'll be sent through to it's own page. For the smaller sections, a slide down box will open with the information. Is this a good way to handle my information architecture? Should I be giving the smaller sub sections their own page for SEO purposes?

• Dynamic Strategy Pattern [migrated]

  - by Karl Barker

  So I'm writing a web service architecture which includes FunctionProvider classes which do the actual processing of requests, and a main Endpoint class which receives and delegates requests to the proper FunctionProvider. I don't know exactly the FunctionProviders available at runtime, so I need to be able to 'register' (if that's the right word) them with my main Endpoint class, and query them to see if they match an incoming request. public class MyFunc implements FunctionProvider{ static { MyEndpoint.register(MyFunc); } public Boolean matchesRequest(Request req){...} public void processRequest(Request req){...} } public class MyEndpoint{ private static ArrayList<FunctionProvider> functions = new ArrayList<FunctionProvider>(); public void register(Class clz){ functions.add(clz); } public void doPost(Request request){ //find the FunctionProvider in functions //matching the request } } I've really not done much reflective Java like this (and the above is likely wrong, but hopefully demonstrates my intentions). What's the nicest way to implement this without getting hacky?

• About to graduage from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been tough how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code !!! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• How much time do you spend actually developing vs. infrastructure activites?

  - by Can't Tell

  When I'm working I feel like most of the time I'm not doing actual work. For example after making a change to the code in order to test it, I have to first build the project, and start the server(say JBoss). Upon testing, I find that there is another small issue. So I bring down the server, make the changes, build again and start up the server again.The building and bringing the server up/down is not very useful work. Also, the IDE (lets say Eclipse) does things such as updating Maven indexes and building the workspace which take some more time to get things done. Have you come across this kind of situation? Do you have tips on how to overcome/bypass this? Any features on the IDE/build tools that can be helpful? Any architecture/application design/technology that attempts to overcome this?

• Where to start when digging into an existing J2EE codebase?

  - by Jacob Krustchinsky

  I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

• Software Engineering: Off to a Bad Start?

  - by Bob Rhubart

  The opening remarks for Real Software Engineering, Living Social developer Glenn Vanderburg's keynote presentation at QCon 2012 in San Francisco, include this: The people who started the software engineering field and movement, from the very beginning, misunderstood two very important things: software and engineering. And as a result, the field went off in the wrong direction from the very start, and legitimized certain ways of doing things and certain paths of research that really have not been very fruitful. Vanderburg's presentation is fascinating, often funny, and well worth watching, especially in light of how cloud computing and other technological shifts are redefining IT roles.

• Hosting my own SVN repositories

  - by TheAdamGaskins

  I've been experimenting with Google Code and Sourceforge and the like, and am happy with what I've found. The main problem with them, is that you have to have your project be open source to use them, so anybody can edit them. So... is there some way I can have my own svn repositories on my own server? I have FTP access, cpanel, and all that. If it helps any: Operating system Linux cPanel Version 11.26.20 Architecture x86_64 MySQL version 5.0.91-community-log Apache version 2.2.13 PHP version 5.2.11 cPanel Pro 1.0 (RC1)

• Web API Presentation at DC DNUG

  - by Steve Michelotti

  This Tuesday (July 19), I’ll be presenting the ASP.NET Web API at the DC DotNet Users Group. Abstract: Modern web applications have seen an explosion in Web API creation. Twitter, Facebook, Google, Azure, you name it – it is becoming essential to provide a Web API so that consumers can build applications and mashups on top of your services. Web 2.0 has shown a trend away from SOAP towards a REST architecture style. With the new ASP.NET Web API, Microsoft is now providing first-class support for HTTP services including tools to apply the richness of a REST architectural style. This demo heavy presentation will show how the new ASP.NET Web API will enable you to build rich HTTP services in a REST architectural style while leveraging custom media types, custom HTTP handlers, jQuery and more! The presentation will also cover new features of MVC 4 including Razor enhancements, Web Optimizations, and more.

• Ubuntu display - no existent

  - by Patrick M

  My HP Pavillion Dv5 1004nr worked great with Ubuntu up until 11.04. Now, ever since Unity desktop environment the display has been sporadic at best. I was told that the video driver bugs (known and largely ignored) were fixed for the ATI raedon card in my laptop with 13.04. So I installed it. 13.04 doesn't even detect the display. Boots to black screen every time now. Is there ever going to be a fix for the AMD architecture with ATI raedon chipsets? do the developers even care? this has been an issue for years, and no sign of a fix in sight....
