• 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 ?

• 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?

• Software automation testing

  - by dotnet-practitioner

  I work in a .net shop where we need to automate software testing. We write ASP.net web apps, web services, windows services, scheduled console application. Back end for all these applications is SQL Server. We would like to automate testing of any bug fixes, any where from web UI change to, middle tier .net code change to sql code change. This tool would be used by programmers to do unit test and played back in different test environments to ensure that bug fix is test correctly in all the environments including the produciton environment. This test would be executed by different teams such as QA, Build, and production site testers. What tool or approach do you recommend?

• 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?

• How much faster is a database running in RAM?

  - by orokusaki

  I"m looking to run PostgreSQL in RAM for performance enhancement. The database isn't more than 1GB and shouldn't ever grow to more than 5GB. Is it worth doing? Are there any benchmarks out there? Is it buggy? My second major concern is: How easy is it to back things up when it's running purely in RAM. Is this just like using RAM as tier 1 HD, or is it much more complicated?

• 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.

• 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....

• 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)

Suppose there is a table products. I jus want to display the table data in a web page. I hav ROR installed and working. I have created a project by giving rails_apps rails demo The command prompt created some folders inside a folder called demo. Though i have read one or two tutorials i am not exactly clear about the working or the cycle of MVC. Can anyone please give some basic idea. I have managed to skim through the initial pages of Agile Web Development Through Rails. Also, please give me some usefull links on the net. That would really help me.

• 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?

• 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.

• Need help in filtering records based on radius value in solr

  - by kshama

  Hi, I am using solr with Lucene spatial 2.9.1 as per http://www.ibm.com/developerworks/java/library/j-spatial/ I want to write a query, that will retrieve records within a given radius using hsin function, and using cartesian tiers as filters. So i wrote query like this http://localhost:8983/solr/select/?q=body:engineering colleges^0 AND _val_:"recip(hsin(0.227486,1.354193 , lat_rad, lng_rad, 4), 1, 1, 0)"^100 &&fq={!tier x=13.033993 y=77.589569 radians=false dist=4 prefix=tier_ unit=m} My records include many US records and few Indian records. For US records filtering based on radius is working fine. But for Indian records its not varying even if i change the radius . So can any one tell me if anything is wrong with the query or is there any configuration issues related to solr in order to make this work, or since record density is very less for Indian records filtering is not happening properly.Am not able to figure it out. Thanks in advance.

• Why is GXHC_gx_session_id appended to URLs?

  - by Nariman

  Based on my limited understanding of this parameter [1] it seems to be used in representing cookieless session IDs in java applications... but strangely, we're now noticing that a 3-year-old .NET stack is now appearing in Bing SERPs with GXHC_gx_session_id appended to the domain - and we're not alone: http://www.bing.com/search?q=GXHC_gx_session_id http://www.google.ca/#hl=en&q=GXHC_gx_session_id When comparing Google SERPs to Bing SERPs there are some inconsistencies in whether a particular site carries this parameter - is it then a bing-specific issue only? What else could cause this parameter to be appended to indexed URLs if the target environment (anything behind the load balancers) isn't running java?

• Looking for a Silverlight 3 or 4 Menu control providing decent keyboard support.

  - by Geo

  I've an N-Tier application using Silverlight for the client. The customer as one particular request - I thought was more than reasonable: all actions – including menu navigation – has to be available through keyboard. When I tried Silverlight 4 I was surprised not to find any menu control so I downloaded several open source and commercial menu controls. I was very disappointed, after having searched for a couple of hours I didn’t manage to find any control that provide a decent keyboard support. Most controls provide no support or some basic support but not one control enabled to gain focus on the first item through the keyboard. You are able to use the keyboard (arrow keys) but you need first to select the control with the mouse! Not one control provided support for Keyboard shortcuts. Does anyone know of any Silverlight control providing descent support?

• 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.

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?
