• Editor's Notebook: Of Slobber Pots and Flux Capacitors

  - by user462779

  Just wrapping up the contents of the November 2012 issue of Profit... I found this snippet of an interview I did with Team Oracle mechanics Clyde Greene and Chad Colberg when I was in Gary, IN this summer working on a photo shoot about Team Oracle for the current issue. We were standing around in a hangar as the Team prepared for the Chicago Air and Water Show, chatting about the engineering and design of the Oracle Challenger III aerobatic plane. Pick up a copy of Profit's November 2012 and read what Team Oracle pilot Sean D. Tucker has to say about the Oracle Challenger III and get a closer look at the plane. I'll drop a link into this blog entry as soon as the story is available. Your editor, greasy and stooped after a red eye flight, talks with Sean D. Tucker about stunt flying.

• Cheese with vaapi

  - by MetaDark

  Hi, I am using a Dell Inspiron Mini 10 with GMA500 video drivers. GMA500 fixes resolution issues and enables video acceleration. The only problem with the GMA500 drivers I am having is that I can not find a fix for the webcam program called cheese, and I can't find a way to enable the vaapi (Video Acceleration API) backend. Videos don't work with the GMA500 (without vaapi) and I cannot properly use cheese. If anyone can help me out with this I will be grateful because Google isn't helping me much with this problem.

• Is Haskell's type system an obstacle to understanding functional programming?

  - by FarmBoy

  I'm studying Haskell for the purpose of understanding functional programming, with the expectation that I'll apply the insight that I gain in other languages (Groovy, Python, JavaScript mainly.) I choose Haskell because I had the impression that it is very purely functional, and wouldn't allow for any reliance on state. I did not choose to learn Haskell because I was interested in navigating an extremely rigid type system. My question is this: Is a strong type system a necessary by-product of an extremely pure functional language, or is this an unrelated design choice particular to Haskell? If it is the latter, I'm curious what would be the most purely functional language that is dynamically typed. I'm not particularly opposed to strong typing, it has its place, but I'm having a hard time seeing how it benefits me in this educational endeavor.

• How to best 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.

• XNA GUI: Creating a 'scroll pane' widget

  - by Keith Myers

  I'm trying to create a simple GUI system and am currently stuck on how to implement a textarea with a scrollbar. In other words, the text is too large to fit into the view area. I want to learn how to do this, so I'd rather not use an already rolled API. I believe this could be done if the text were part of a texture, but if the game had a lot of unique dialog, this seems expensive. I researched creating a texture on the fly and writing to it, but came up with nothing. Any suggested strategies would be appreciated. I believe it boils down to: text in a texture and how? Or something I have not thought of...

• Client/Server Application Using Google App Engine

  - by Kevin Zhang

  Can someone please advise me what is the possible solution of using GAE to make a Client/Serer Application? As far as I know, GAE is designed to do web applications. What I want to do is to have a Java Client(Swing based) deployed on a number of computers and deploy the server on GAE. I found an example on GAE website which teaches how to make a SOAP service using GAE, but I don't know whether using SOAP is a good idea for client/server applications. Can someone give me some hints about how to design this system and what technology should be used? Any advices are welcome. Many thanks.

• How to send credentials to linkedIn website and get oauth_verifier without signing in again [closed]

  - by akash kumar

  I am facing a problem sending credentials to another website so that I can login the user (automatically, not clicked on sign in here) and get an oauth_verifier value. I want to send the email address and the password through a form (submit button) from my website (e.g. a Liferay portal) to another website (e.g. LinkedIn), so that it automatically returns an oauth_verifier to my website. That means I don't want the user of my website to submit his email and password to LinkedIn again. My goal is to take the email and password of the user in my website and show the user his LinkedIn connection, message, job posting (again, in my website, not LinkedIn). I dont want the user redirected to the LinkedIn website to sign in there and then come back to my website. I have taken a consumer key and a secret key from LinkedIn for my web aplication. I am using the LinkedIn API and getting oauth_verifier for access token but in order to login, I have to take user to LinkedIn to sign in, while I want it to happen in the backend.

• Implementation of instance testing in Java, C++, C#

  - by Jake

  For curiosity purposes as well as understanding what they entail in a program, I'm curious as to how instance testing (instanceof/is/using dynamic_cast in c++) works. I've tried to google it (particularly for java) but the only pages that come up are tutorials on how to use the operator. How do the implementations vary across those langauges? How do they treat classes with identical signatures? Also, it's been drilled into my head that using instance testing is a mark of bad design. Why exactly is this? When is that applicable, instanceof should still be used in methods like .equals() and such right? I was also thinking of this in the context of exception handling, again particularly in Java. When you have mutliple catch statements, how does that work? Is that instance testing or is it just resolved during compilation where each thrown exception would go to?

• How to manage an issue tracker's backlog

  - by Josh Kelley

  We've been dutifully using Trac for several years now, and our "active tickets" list has grown to almost 200 items. These include bugs that are too low priority and too complicated to fix for now, feature requests that have been deferred, issues that have never really generated complaints but everyone agrees ought to be fixed someday, planned code refactorings and other design infelicities that we don't want to lose track of, etc. As a result, with almost 200 of these issues, the list is almost overwhelming; it's no longer useful as a source of what needs to be worked on right now. What's the best way to keep track of issues of this sort? Part of the problem is that some of these issues are such a low priority that they may never get done. I hate to lose track of these items (similar to not wanting to throw something out of my house in case I might need it someday); do I need to throw them out regardless (by marking them as wontfix) and assume I can find them in the future if I ever do need them?

• So long wizards!

  - by geekrutherford

  In an effort to make an application more robust I have been switching to a server-side method of tracking record selections vs. client side.   The pages relying on record selections utilized the ASP.NET Wizard control which seemed like a good idea originally. Unfortunately, the design of the control is not all that flexible. It appears to want to center everything vertically which might not be a problem if it did not always use the vertical size of the largest Wizard Step for positioning.   So, I am ripping out the Wizard controls and replacing with simple Panel controls that are turned on/off. Much cleaner and presentable.

• Make my website dynamically loaded data available to Facebook Open Graph Object Scrapper

  - by fvaliquette

  Here is the design of my web site: The user enter myWebsite.com/a/1 .htaccess rules redirect to myWebsite.com/b Now the JavaScript ExtJS library is loading. Extracting the value from the URL (in this case it is “1”) Loading ./xml/1.xml From 1.xml setting the Open Graph data (Title, type, image, etc) Loading data that will be shown to the user from 1.xml into the website. My question is: How can I make the Open Graph data available to Facebook? Facebook do not to load my ExtJS JavaScript Library before extracting the Open Graph Object values from the HTML. Is there an easy solution to this problem? The only solutions I found is to make statics web pages or dynamically pages rendered on the server side but I would like to avoid these since my web page implementation is already finished and I would like to avoid re working on it.

• IntelliJ with Maven compilation

  - by Mik378

  I have a project that needs Hibernate jars. I added them as dependencies in the pom.xml and Maven compiles my project well. However, in the IDE, all annotations and calls to Hibernate API are marked as unresolved (red). How could I get IntelliJ being able to resolve them ? Is there a way to use Maven when I click on Build Project ? (ctrl+F9) Also, I am confused with the concept of facets within IntelliJ. Do I need them, let's say JPA facets to enable Persistence assistant etc... or there's an option to let Maven take care about ?

• I can't program because old coding style. This is normal to programmers?

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: don't have comments don't have functions (50, 100, 200, 300 or more lines executed in sequence) uses a lot of if statements with a lot of paths has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) uses a language I am unfamiliar with (Visual FoxPro 8 from 2002) I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way?

• protecting css selectors on large website

  - by Tim

  I have content that appears within a corporate website inside an iframe. Several departments contribute their own CSS files to manage the overall UI and design. My problem is that they may use selectors for elements like td (for instance), without notice. Of course that will affect my own content in the frame unless I add a class to every td. I'm just using td as an example: the generic style for any element could change without notice. Is there any method/convention/practice I can use to protect my own styling?

• C#/.net features to cut off assuming no backward compatibility needed?

  - by Gulshan

  Any product or framework evolves. Mainly it's done to catch up the needs of it's users, leverage new computing powers and simply make it better. Sometimes the primary design goal also changes with the product. C# or .net framework is no exception. As we see, the present day 4th version is very much different comparing with the first one. But thing comes as a barricade to this evolution- backward compatibility. In most of frameworks/products there are features would have been cut off if there was no need to support backward compatibility. According to you, what are these features in C#/.net? Please mention one feature per answer.

• Do employers prefer software engineering over CS majors?

  - by Joey Green

  I'm in grad school at a university that was one of the first to have a software engineering accredited program. My undergrad is in CS. An employer recently recruited at our university and hired 5 SE majors. None of them were CS. Do employers prefer software engineering majors? The reason I ask is because I can focus on many different areas during my graduate studies and really want to take the classes that will help me land a great job. Right now I'm either going to use CUDA and parallelize an advanced ray-tracer for a graduate project or do research on non-photo-realistic rendering in augmented reality. Pursuing these would leave very little SE classes in my schedule. If I went the software engineering route, I would probably either do research into data-oriented programming or software design complexity. Sometimes I think when I'm 40 and look back will it matter at all? For some reason I'm thinking not.
