• Is it important to obfuscate C++ application code?

  - by user827992

  In the Java world, it seems to sometimes be a problem, but, what about C++? Are there different solutions? I was thinking about the fact that someone can replace the C++ library of a specific OS with a different version of the same library, but full of debug symbols to understand what my code does. IS tt a good thing to use standard or popular libraries? This can also happen with some dll library under Windows replaced with the "debug version" of that library. Is it better to prefer static compilation? In commercial applications, I see that for the core of their app they compile everything statically and for the most part the dlls (dynamic libraries in general) are used to offer some third party technologies like anti-piracy solutions (I see this in many games), GUI library (like Qt), OS libraries, etc. Is static compilation the equivalent to obfuscation in the Java world? In better terms, is it the best and most affordable solution to protect your code?

• Listing technologies on a resume for a software position when your background is game programming?

  - by Ford

  So I'm thinking about applying for a entry level position in the software industry but my limited experience working and all my notable experience in college is with game technologies. Sure, the languages transfer over well but most of the technologies I have experience with are all related to graphics programming, engines of various types, and such, and do not transfer over at all. I feel like it would be inappropriate to just take my game programming resume and basically replace the word game with software for the reasons mentioned but on the other hand if I take them out I will only have languages and some technologies that I have some small passing experience with- which will obviously not reflect well on me. Should I leave them out or put them in, and if so how can I spin them to be appropriate?

• Is it a good idea to simplify an character -driven game engine to the point it's unnecessary to learn scripting/programming ?

  - by jokoon

  I remember, and I still think, that one cannot even make a prototyped 3D game to test just simple behaviors without using gigantic tools like unity or knowing extensive C++ programming, design pattern, a decent or basic 3D engine, etc. Now I'm wondering, since I know programming, that I'm still more lucky that the ones who need to learn programming prior to know how to make something: even scripted engines such as unity are not for kids, and to my sense they tend to dictate their ways of doing things, which is not the case with engine like ogre or irrlicht. I remember toying a little with the blender game engine, it was possible to link states or something I don't remember very well. Now I'm thinking that character driven games occupies a big part of the game market. Do you think it is a good idea to make a character-controlled oriented game engine which allows only to build AI instead of anything else ?

• Bitbucket and a small development house

  - by Marlon

  I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of shared folders! In the process of rolling this out, I am thinking of different strategies to manage our stuff and I am leaning towards using Bitbucket as our "central" repository. The projects in Bitbucket will solely be private projects and everyone will push and pull from there. I am open to different suggestions, but has anyone got a similar setup? If so, what caveats have you encountered?

• Design leaderboard ratings for quiz games

  - by PeterK

  Back in March 2011 i started the following post: How to design a leaderboard? Now my quiz game have been out for approximately a year and sold pretty decently. I am working on to update the game design and is again looking into the leaderboard design to make it better as i am not happy with it. Currently i rate players on number of correct answers, which is not good as it does not consider things like number of games, difficulty levels etc. I also have "extended" stats behind the UITableView (Leaderboard). A player can play based on three levels of difficulty: hard, medium or easy Difficulty levels can be mixed between players in a game Each game can be one to six players, so there can be single games or duels Between 2 and 30 questions per game As i am considering integrating Game Center Leaderboard i need to design a better rating system so i would like to ask for some ideas how to do the rating based on the above. I am thinking about how much a point would be worth and what it includes.

• Should I go back to the same company ?

  - by vinoth

  Hi , I quit the company I was working for(lets call it XYZ) and joined another company . When I quit the company I had very little Software development experience . I thought the rest of the world is a better place . So I complained about the word quality and all that while i quit . One year has taught me a lot of things and I feel XYZ is a much better place (in terms of freedom and decision making in work) . Is it ok to go back ? I am thinking a lot whether to go or not because I quit complaining the nature of work and now I am going back for the same thing . Also I am kind of not very sure to go to other places because , the work and quality are not predictable (I am might become disappointed again ) . Have any of guys been in the same situation before ?

• Doubts regarding the behaviour of 'autoremove' command and '--auto-remove' flag

  - by Jasper Loy

  After reading several man pages and forums, I thought that running 'apt-get autoremove' without any following argument removes all unused dependencies left on the system, while running 'apt-get autoremove xxx' removes xxx together with its unused dependencies. However I found this to be not true. Running 'apt-get autoremove xxx' not only removes xxx together with its unused dependencies, it also removes all other unused dependencies. So I tried to run 'apt-get remove --auto-remove xxx', thinking that this would remove only xxx and its unused dependencies. To my surprise, this also removed xxx, its unused dependencies and all other unused dependencies. Is this the intended behaviour of the commands or a bug? Is there any quick way to remove xxx and its unused dependencies without removing other unused dependencies?

• What has the most efficient intersection test against an AABB tree - OBB, Cylinder or Capsule?

  - by identitycrisisuk

  I'm currently trying to find collisions in 3D between a tighter volume than an AABB and a tree of AABB volumes. I just need to know whether they are intersecting, no closest distance or collision response. An OBB, Cylinder or Capsule would all roughly fit these purposes but Cylinder and Capsule were the first thing I thought of, which I have found little information about detecting intersections online. Am I right in thinking that they would always be more complex to perform Separating Axis Tests on even though they might seem like simpler shapes? I figure by the time I get my head around SAT for curved shapes I could have done the thing with OBBs but I wanted to find out for sure.

• An "Invoke Update Manager to update everything and shutdown" script after idle for x minutes?

  - by unknownthreat

  I have Ubuntu 10.10 installed on a machine for my parents. The thing is they never request updates from Update Manager even the manager itself prompted them so. Moreover, when they are done with whatever they are doing on Ubuntu, they always leave the computer on. And I always have to come back and shut the machine down. Sometimes, the computer even sit idle for hours. So I want to know whether this is possible in Ubuntu. I am thinking of a script that will be activated after the machine is idle for x minutes. When x minutes have elapsed, Update Manager will automatically update everything listed. (I recall that you need the admin password for this, so is there a workaround?) After all the updates are done, the machine will automatically shutdown. Is this possible?

• Cannot use broadband in Kubuntu

  - by Amanz Linux

  I have 5 months of experience using ubuntu 10:10. And it is clear it is suitable for broadband use. For Kubuntu, I have thoroughly tried everything available, using the 10:10 Kubuntu CD that I have had for the last week. It is very appealing, but in the meantime I am unable to use broadband in Kubuntu. I've tried and tried, thinking that it was possible that the use of broadband in Kubuntu was the same as in Ubuntu, so I have attempted to use broadband just as I used it in ubuntu. But I have failed to successfully test the broadband. Kubuntu was much different from ubuntu. Can anyone help me solve this problem?

• What does a Game Designer do? what skills do they need?

  - by xenoterracide

  I know someone who is thinking about getting into game design, and I wondered, what does the job game designer entail? what tools do you have to learn how to use? what unique skills do you need? what exactly is it you'd do from day to day. I may be wording this a bit wrong because I'm not sure if the college program is become a game designer or learn game design. but I think the same questions apply either way.

• initial Class design: access modifiers and no-arg constructors

  - by yas

  Context: Student working through Class design in personal/side project for Summer. I've never written anything implemented by others or had to maintain code. Trying to maximize encapsulation and imagining what would make code easy to maintain. Concept: Tight/Loose Class design where Tight and Loose refer to access modifiers and constructors. Tight: initially, everything, including setters, is private and a no-arg constructor is not provided (only a full constructor). Loose: not Tight Exceptions: the obvious like toString Reasoning: If code, at the very beginning, is tight, then it should be guaranteed that changes, with respect to access/creation, should never damage existing implementations. The loosening of code happens incrementally and must be thought through, justified, and safe (validated). Benefit: Existing implementing code should not break if changes are made later. Cost: Takes more time to create. Since this is my own thinking, I hope to get feedback as to whether I should push to work this way. Good idea or bad idea?

• How to I teach my artist to do arts for games?

  - by Holm76

  So my girlfriend is an artist and I'm a programmer and we often talk about joining talents and doing some small games or other fun stuff for the different popular platforms currently out. But because I haven't really done any serious games development yet I have a hard time explaining to her how she should create or package the assets she'd make so we always end up not doing nothing about it. What I'm mostly thinking about here is when doing frame by frame animation. I know sprite sheets are used for this kind of thing but then comes questions like frames per second and stuff like like that. Not program wise but art wise. Is there a reference site or sites out there that teach someone with the skills of art how to manage and arrange the assets in sprite sheets and other stuff in words that artists understand?

• Is there a phrase or word to describe an algorithim or programme is complete in that given any value for its arguments there is a predictable outcome?

  - by Mrk Mnl

  Is there a phrase to describe an algorithim or programme is complete in that given any possible value for its arguments there is a predicatable outcome? i.e. all the ramifications have been considered whatever the context? A simple example would be the below function: function returns string get_item_type(int type_no) { if(type_no < 10) return "hockey stick" else if (type_no < 20) return "bulldozer" else return "unknown" } (excuse the dismal pseudo code) No matter what number is supplied all possibiblites are catered for. My question is: is there a word to fill the blank here: "get_item_type() is ______ complete" ? (The answer is not Turing Complete - that is something quite different - but I annoyingly always think of something as "Turing Complete" when I am thinking of the above).

• Why is Google still not indexing my !# website?

  - by Zubair

  I have been working on a website which uses #! (2minutecv.com), but even after 6 weeks of the site up and running and conforming to the Google hash bang guidelines stated here, you can still see that Google still hasn't indexed the site yet. For example if you use Google to search for 2MinuteCV.com benefits it does not find this page which is referenced from the homepage. Can anyone tell me why Google isn't indexing this website? Update: Thanks for al lthe help with this answer. So just to make sure I understand what is wrong. According to the answers Google never actually indexes the pages after the Javascript has run. I need to create a "shadow site" which google indexes (which google calls HTNL snapshots). If I am right in thinking this then I can pick a winner for the bounty

• How to keep a team well-trained?

  - by PierrOz

  Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

• Tracking first visit date in Google Analytics

  - by dusan

  I want track a site's visitor retention using Google Analytics, to see if unregistered users are returning to it, within a time frame of 2+ months from now. This blog post seems to be on the right track, but I want to track unregistered users, so I don't have a "join date" or similar variable at my disposal. This other blog post suggests using all 5 GA custom variables, using the first variable slot on the first week, variable 2 on week 2, etc. This method will allow me to track 5 weeks of visitors. I want to track more than 5 weeks of visitors, so I was thinking on using two custom variables in GA: visitor's first visit date, and visitor's last visit date. How I can save the first visit date? Because if I save another value in the same slot the old value will be overwritten, and I don't know how reliable is to save that variable conditionally (reading the __utmv cookie to check whether the "first visit date" is set, if it isn't set I save the current date)

• Contract Programming - Deposit % and Payment Methods? Any advice is appreciated

  - by Rick

  I'm pretty new to doing contract work and finally landed a decent paying project. The guy actually offered to put down a deposit and I'm just wondering what percentage I should consider asking for. I was thinking around 25% since its not a terribly large project (only about 20 hours). Also, I can't use PayPal (have had a terrible experience with them freezing funds for no good reason) so I'm wondering if anyone can suggest other methods for the client to send the deposit / payment. I want to make it as easy as possible for them.. thanks for any advice

• Houston We have a Problem with Silverlight Client OM&hellip;

  - by MOSSLover

  So I was playing around with NavigationNodeCollection, which is basically like SPNavigationNodeCollection just to make sure it worked without a hitch…Here is a little sample snippet of what should work: Unfortunately, you get a nice little javascript error that does not allow you to access the child nodes.  I tried a foreach() loop that gets a NavigationNode for each parent then loops through the NavigationNode.Children that did not work either.  I threw in two ExecuteQueryAsync statements thinking that would help, unfortunately adding a second statement provides no different results.  This appears to be a bug in the Silverlight Client Object Model.  I reported the error.  Hopefully, we get a fix by RTM so that we can use the easier method to get items into Silverlight, otherwise it’s back to WCF and cross domain policies.  We all love cross domain policies right?

• How to approach iOS web clip app "download"?

  - by Ryan

  We have our main site at: http://mysite.com which we don't want to alter. Then we have our web clip app at: http://mysite.com/app/ If someone visits the app URL in normal Safari then the Safari UI will still display. But if the user adds the app URL to their home screen, and then they tap that icon they will launch the app URL without the Safari UI as intended. My question is how do you go about getting the user to use the web clip app from their home screen when they start from mysite.com? What I'm thinking is that we have a link on mysite.com that points to mysite.com/app/. Then when they click that /app/ link they'll go to the app but it won't be in "app mode". Can I detect that it's not in app mode and display a message like "add this page to your home screen to use the app"? And then when they do visit in app mode obviously just let the app run.

• Getting graduates up to speed?

  - by Simon

  This question got me thinking about how comapnies deal with newly-hired graduated. Do experienced programmers expect CS graduates to write clean code (by clean I mean code easily understandable by others — maybe that is too much to expect?) Or do significant portion of graduates at your place (if any) just end up testing and fixing small bugs on existing applications? And, even if they do bug fixes, do you end up spending double the amount of time just checking they did not end up breaking anything and creating new bugs? How do you deal with such scenarios when pair programming and code reviews are not available options (for reasons such as personal deadlines), and also what techniques did you find to get fresh graduate up to speed? Some suggestions would be great.

• Handling SMS/email convergence: how does a good business app do it?

  - by Tim Cooper

  I'm writing a school administration software package, but it strikes me that many developers will face this same issue: when communicating with users, should you use email or SMS or both, and should you treat them as fundamentally equivalent channels such that any message can get sent using any media, (with long and short forms of the message template obviously) or should different business functions be specifically tailored to each of the 3? This question got kicked off "StackOverflow" for being overly general, so I'm hoping it's not too general for this site - the answers will no doubt be subjective but "you don't need to write a whole book to answer the question". I'm particularly interested in people who have direct experience of having written comparable business applications. Sub-questions: Do I treat SMS as "moderately secure" and email as less secure? (I'm thinking about booking tokens for parent/teacher nights, permission slips for excursions, absence explanation notes - so high security is not a requirement for us, although medium security is) Is it annoying for users to receive the same message on multiple channels? Should we have a unified framework that reports on delivery or lack thereof of emails and SMS's?

• What is the value of the Cloudera Hadoop Certification for people new to the IT industry?

  - by Saumitra

  I am a software developer with 8 months of experience in the IT industry, currently working on the development of tools for BIG DATA analytics. I have learned Hadoop basics on my own and I am pretty comfortable with writing MapReduce Jobs, PIG, HIVE, Flume and other related projects. I am thinking of taking the exam for the Cloudera Hadoop Certification. Will this certification add value, considering that I have less than 1 year of experience? Many of the jobs I've seen relating to Hadoop require at least 3 years of experience. Should I invest more time in learning Hadoop and improving my skills to take this certification?

• Unity launcher full - Need more icons

  - by Martin Wildam

  I have already reduced the Unity launcher icons to 32 but still the space is exhausted already with my most-used programs. Basically I have to scroll often in the unity launcher bar with is annoying. So far (Ubuntu 10.04) I had those icons as mini ones in the top panel (smaller icons and wider space) where they could fit all. I was thinking already of sub-launchers or something the like but could not find something like the drawer was in Gnome 2. I am using Ubuntu at home and in the office. I am a consultant and need a lot of stuff on a regular basis. To put links at the desktop does not make sense because of the many windows that I usually have open there is hardly ever a piece of the desktop looking through. How do you - power users get keep most-used programs at reach (and I mean <= 2 clicks away)?
