  • 13.10 qtcreateor 271 wont work

    - by bernd feinman
    Just installed ubuntu 13.10 x86 with all updates. I then installed qt4 libraries and qt creator 271: sudo apt-get install build-essentials sudo apt-get install libqt4-dev sudi apt-get install qtcreator Both installed successfully, and i can launch qt creator, but then i get a black window when i switch to "examples" or "development": http://i.imgur.com/koi6S9S.png The windows cannot be closed. I am guessing because qtcreator somehow cannot find the qt version i installed. This is the settings page: http://i.imgur.com/OgAKH7S.png what to do?

  • How does Python compile some its code in C?

    - by Howcan
    I read that some constructs of Python are more efficient because they are compiled in C. https://wiki.python.org/moin/PythonSpeed/PerformanceTips Some of the examples used were map() and filter(). I was wondering how Python is able to do this? It's generally interpreted, so how does some of the code get compiled while another is interpreted - and in a different language? Why not just compile the whole thing?

  • devlog & community engagement: where to start?

    - by Lai Yu-Hsuan
    I heard one of the ways to promote games is to start a development log, but I haven't gotten it to this day. Where should I start? Though I have had a blog, this idea seems a infinite loop: Writing blog to promote game, then I have to promote my blog and nothing becomes easier. So, where do you post devlog? Or you post other interesting things in some communities? Are there some examples that I can learn from?

  • use of Enum with flags in practice?

    - by user576510
    I just have read some stuff on enum today. Use of flags with enum was something interesting and new for me. But often practice and theoretical uses are different. I go through many articles they examples they quoted were good to get the concept but am still wondering in what situations one can use Enums with flag to store multiple values? Will highly appreciate if you please can share your practical experience of using enum with flags.

  • Can someone explain how a GUI works and when I should start using one?

    - by David
    I've been learning C++ for about a month now, and before I go any further, I'd like to clear up this tedious question I keep on having. I know what a GUI is, but I don't really know how it works, and maybe examples of popular ones...? Although I know command line programming is the bare fundamentals, I think it'd be fun messing around with a GUI. Although I have around 3 million other questions, I'll save them :D

    The folks at Retail Touchpoints surveyed 84 retailers on the topic of cross-channel and have published the results in Completing the Cross-Channel Challenge.  Below is an overview video that summarizes the findings and cites retailer examples. One thing is clear: customers demand Commerce Anywhere, the ability to shop when, where, and the way they want.  So retailers are doing what it takes to revamp their business to meet their customers' demands.

  • 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.

  • When is it reasonable to create my own programming language?

    - by Daniel Rikowski
    Are there types of killer applications, classes of algorithmic problems, etc., where it is better, in the long run, to create my own language? PS: Just to be sure, I mean a new programming language and a compiler, not a new compiler for an existing language. EDIT: Thank you for the answers. Can you provide some examples, where it is absolutly unnecessary to create a DSL or cases in which a DSL might be a good idea?

    I am looking for help/links/notes/agorithms/URLs/examples on drawing/rendering spheres in pure Java (so that I can hopefully, one day, generate/render planets with various surfaces & atmospheres) So for the moment, i'd be pretty happy to be able to start off with just drawing a wireframed sphere(s). ps: I don't want to use external libraries like Java3D, JOGL or aftermarket engines like JMonkeyEngine, Would rather keep it as straight Java.

  • How to be successful at BDD Specifications Workshops?

    - by sigo
    Today we tried to introduce BDD in our software development process by having a specification workshop. For this workshop we had 2 developers, 1 tester and 1 business analyst. The workshop lasted 1h30 and by the end of it we managed to figure out some BDD scenarios for our new feature. We tried to focus on finding the scenarios that we could miss, and the difficult ones. At the end of the workshop some people were actually unhappy with the workshop. One developer felt he wasted his time as he was used to be given out the scenarios directly by the business analyst and review them with her. The business analyst didn't feel confident with our scenario coverage (Had a feeling that we could have missed out other important stuff) but more importantly felt that this workshop was also a waste of time as she could have figured out all these scenarios by herself and in a shorter period of time. So my question is how that kind of workshop can actually work. In the theory, given you have a new feature to develop, you put the tree 'amigos' (dev/tester/ba) in the same room so that they can collaborate together on writing the differents requirements for the new feature using examples. I can see all the benefits from that. Specially in term of knowledge sharing and common product/end goal/done vision. But in practice, we still think it is more cost effective to first have a BA to work on his own on the examples and only then to have the scenarios to be reviewed/reworked by the 3 'amigos'. By having the BA to work on his own, we actually feel more confident that we are less going to miss out stuff + we still get to review the scenarios afterward to double check. We don't think than simple brainstorming/deliberate discovery is actually enought to seriously cover all the requirement for a feature. The business analyst is actually the best person for that kind of stuff. The thing we just do is to review what she wrote and see if then we have a common understanding (which could then lead to rewrite some of her scenarios or add new ones she could have missed). This workshop lasted 1h30, and by the end of it, we didn't feel confident enought about wha we did...sure we could have spent more time on it but honestly most people get exhausted after 1h30 of brainstorming. So how can you get that to work effectively in practice ?

  • The Softer Side of Customer Experience

    - by Christina McKeon
    It’s election season in the U.S., and you know what that means. It means I stop by the recycling bin in my garage before entering the house with the contents of my mailbox. A couple of weeks ago, I was doing my usual direct mail purge when I came across a piece from The Container Store®. This piece would have gone straight to the recycling bin, but the title stopped me: Learn what WE STAND FOR! Under full disclaimer, I’m probably a “frequent flier” at The Container Store. One can never be too organized! Now, back to the direct mail piece. I opened it to discover that The Container Store has taken their customer experience beyond “a shopping experience that makes you smile” to giving customers more insight and transparency into how they feel about their employees, the vendors they partner with, and the communities they live in. The direct mail piece included several employees showcasing a skill, hobby or talent with their photo and a personal note that used one word to describe what these employees believe The Container Store stands for. I do not recall the last time I read through an entire piece of direct mail. But this time, I pored over all the comments and photos.  Summer, a salesperson, believes that one word is PASSION. Thomas in distribution center inventory systems chooses the word ACTION. The list goes on to include MATCHLESS, FUN, FAMILY, LOVE, and EMPOWERMENT. The Container Store is running a contest asking you to tell them what nonprofit organization you stand for. Anyone can submit their favorite nonprofit to win cash, products and services from The Container Store. Don’t forget about the softer side of customer experience. With many organizations working feverishly to transform their business into being more customer-centric, it’s easy to get caught up in processes and technology. Focusing on people and social responsibility often falls behind and becomes a lower priority. Keeping people and social responsibility at the forefront is crucial. Your customers will use your processes and technology, but they will see or hear your people and feel their passion. The latter is what they will remember most about your brand. I’m sure there are many other great examples of the softer side of customer experience. Please share your examples in the comments section.

  • Do extra words in url affect SEO?

    Often for technical reasons we end up with some extra words in a url that we would not want to optimize for as they would have no bearing on the content.

Would it behoove us to strip the extra words?

  • NUnit Random Module

    - by Tra5is
    I've noticed something curious. When I attach the VS2010 debugger to the nunit.exe running process I see a loaded module with no path and a randomly generated filename. I tried attaching WinDBG to the exact same instance of NUnit.exe and the module is NOT listed in the module list. I also can't find anything with Google so I'm hoping someone here could help out. Is this normal NUnit behavior or is something sneaky going on? Some examples of the module name: 1xmsg0gj x4max0ed koh9hmef
