  • Online betting system design [closed]

    - by Rafal
    I am a Computer Science student, preparing for my exam in software engineering. I am strugging with answering one of the sample questions to the scenario below. My understanding is that the system design approach should probably be a mixture of agile and plan driven elements but - since I've no practical experience - it's hard for me to decide on the balance and tolls that should be used. I will appreciate any hints from experienced business analysts who were involved in similar kind of projects. Ray Sing is the owner of “Last Betz", a bookmakers with 7 outlets across Louth and Meath. With the advent of smartphones Ray would now like to allow his clients to place their bets online using their mobile devices. Clients would register for an account and password and would log their credit card details via the Last Betz website. To begin using the facility customers must 'load' their accounts with 100 euros. Any winnings, minus commission, will be placed in the account whilst any losses will be automatically deducted from the account. Assuming you have been selected to develop the above system: How would you approach the design of this system? Discuss the design methods and models you would use.

  • How can I enable Unity 3d after installing Bumblebee? GLX Problems

    - by ashley
    I'm new to Ubuntu, I'm running 12.04 64 Bit on a Dell XPS L207x with a Nvidia GT555M card. From what I could understand online I needed to install Bumblebee to get the most out of the Optimus system and better battery life. I can test the Bumblebee is working by running optirun glxgears for example. If I run just glxgears then I get the following error Error: couldn't get an RGB, Double-buffered visual. I'm also unable to run Unity 3d, which I would very much like. I'd greatly appreciate any and all help, please be gentle.

  • Applying languages / locale selectively: is it possible?

    - by Aron Rotteveel
    I am a Dutch user and prefer the my local date & time format, system wide. I have no trouble speaking or understanding English and find it very useful to have the rest of my system configured in English to make my life easier when I need to Google a term, for example. Is it possible to apply the a local date/time/currency/etc. format to the system, while maintaining English menu & dialog captions? EDIT: output from locale and posted screens of current settings: LANG=en_US.utf8 LANGUAGE=en LC_CTYPE="en_US.utf8" LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8" LC_COLLATE="en_US.utf8" LC_MONETARY="en_US.utf8" LC_MESSAGES="en_US.utf8" LC_PAPER="en_US.utf8" LC_NAME="en_US.utf8" LC_ADDRESS="en_US.utf8" LC_TELEPHONE="en_US.utf8" LC_MEASUREMENT="en_US.utf8" LC_IDENTIFICATION="en_US.utf8" LC_ALL=

  • Difference in fans on Windows 7 and Ubuntu 12.04

    - by Timo
    I have bought a Hp Pavilion DV7 with Core i7 CPU and installed Ubuntu 12.04 on dual boot with Windows 7 alongside. Apart from the difference in battery life (although that's fixed with Jupiter), I have another problem with the fans. On Windows my fans work perfectly and the laptop is cool, but it seems to overheat in Ubuntu. It becomes quite hot and it looks like my fans are not working under Ubuntu. I think I'm having the same problem as How can I keep the cpu temp low?, but since I cannot comment because of the lack of reputation (?), I post the question as a new thread. I think the result of the overheating is that my keyboard doesn't seem to follow when I start typing a long text. It just freezes and types the last letter multiple times. For example: when I type the word freezes, it shows freeeee so the zes changed into eee...

  • Is there any working, usable video editing software for ubuntu?

    - by matteo
    Is there any decently stable video editing software for Ubuntu, that won't crash at every mouse click and that you can actually use for doing things that you need? (as opposed to for the sake of testing it) I've tried out pitivi and cinelerra but they are completely unstable (they both crash very often) besides having very poorly designed interfaces... Is there any better option or are we still stuck to Windows and Mac OS for even the most basic (but real-life) video editing? Even something as basic as Avidemux would be fine in many situations (not all) if only it worked (i.e. if not rendered completely useless by its bugs).

  • Interviews by Software Companies

    - by Glenn Nelson
    I have been chosen as one of the 12 final people for a full out scholarship to the college of my choice and it is paid for by a software company so long as I major in Computer Science.I have already had to write an essay on what has most shaped my life (Programming being it) and that was the basis for the interview decision. I now have to go in for an interview with people from the company for the final decision in a week. I do believe I have a good foundation in computer science already. I have roughly 4 years of programming experience in Java, C++, ASM and your typical web stuff. I have done everything from making my own CMS for my site to an assembler to network file transfer applications. That said what types of questions should I expect in an interview of this sort? Do I seem reasonably knowledgeable?

  • Hallmarks of a Professional PHP Programmer

    - by Scotty C.
    I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

  • Little Wheel Is An Atmospheric and Engaging Point-and-Click Adventure

    - by Jason Fitzpatrick
    If you’re a fan of the resurgence of highly stylized and atmospheric adventure games–such as Spirit, World of Goo, and the like–you’ll definitely want to check out this well executed, free, and more than a little bit charming browser-based game. Little Wheel is set in a world of robots where, 10,000 years ago, a terrible accident at the central power plant left all the robots without power. The entire robot world went into a deep sleep and now, thanks to a freak lightning strike, one little robot has woken up. Your job, as that little robot, is to navigate the world of Little Wheel and help bring it back to life. Hit up the link below to play the game for free–the quality of the visual and audio design make going full screen and turning the speakers on a must.

  • How to verify real people?

    - by Gerben Jacobs
    For a music community, I want bands to be able to verify themselves. What is the best way to do this? For example I could let the record label mail me, but some bands are indepedent. I could also ask them to put a 'code' on their website or Facebook page and then check manually. I'm not per se looking for a waterproof solution, so no scanning of real life documents and I'm okay with doing the checks manually. In other words, how can you verify real people with their virtual presence?

  • New to world of Ubuntu

    - by Michael Raymond Cheney
    I've been running Ubuntu 13.04 since June 2013, and upgrading to 13.10 as we speak.(Note I own total 3 laptops.) My goal is to have one complete Linux machine and one dual boot, and third well (he is a newer Lenovo with Windows 8.1 and is touch screen.) but I want to learn Ubuntu life and further myself with using it for everyday use, but I'm not very fluid in Linux usage and hoping to find people who have a love for teaching others how to be one with the BEST OS IN THE WORLD! Hope I've got few people wanting to teach or give good instruction for success. ~Mike Cheney~

  • Reasons NOT to open source not-for-profit code?

    - by naught101
    I am a big fan of open source code. I think I understand most of the advantages of going open source. I'm a science student researcher, and I have to work with quite a surprising amount of software and code that is not open source (either it's proprietary, or it's not public). I can't really see a good reason for this, and I can see that the code, and people using it, would definitely benefit from being more public (if nothing else, in science it's vital that your results can be replicated if necessary, and that's much harder if others don't have access to your code). Before I go out and start proselytising, I want to know: are there any good arguments for not releasing not-for-profit code publicly, and with an OSI-compliant license? (I realise there are a few similar questions on SE, but most focus on situations where the code is primarily used for making money, and I couldn't much relevant in the answers.) Clarification: By "not-for-profit", I am including downstream profit motives, such as parent-company brand-recognition and investor profit expectations. In other words, the question relates only to software for which there is NO profit motive tied to the software what so ever.

  • What are the 'must know' GDB commands?

    - by Chris Smith
    I'm starting to get the hang of GDB, but everything still feels much slower than when debugging in Eclipse or Visual Studio. Are there any GDB commands you find particularly useful/productive? My life became dramatically better when I discovered: list - Display source code near the current instruction But that is still pretty basic. (And unnecessary when running GDB from Emacs.) Is there any way to do things like setup a watch window? (Print and update the result of an expression every time execution stops.)

  • I'm not sure if this is a valid Ubuntu bug to file

    - by Ian Hincks
    I was in the process of filing an bug on Launchpad, but I had second thoughts because there were so many threatening warnings of the effect, "Don't file a bug report unless you're sure it's a bug, and you should really provide a package name". The problem I have, and I've had it for years, is the following: When I'm installing Ubuntu, it asks me to type in my location before it asks me what my keyboard layout is. Using a QWERTY keyboard but with the buttons popped of and in the Dvorak order, this is annoying, because it is assumes I am using a QWERTY keyboard, and so I have to guess at where all the QWERTY keys are to spell my city's name. It seems like it would make more sense to switch the order of these two questions. (I'll be the first person to admit that this is a very minor problem that has probably wasted less than 2 minutes of my life in total -- but it's the principle of the thing :p) So my question is: is this order there for a particular reason, and if it isn't, is it appropriate to file it as a bug, and under which package name?

  • How to fill certain application design learning "gaps"?

    - by e4rthdog
    In life it doesnt matter if you do one thing for 15 years. You will end up waking one day and asking stuff that are equal to "how do i walk?" :) My specific question is that as a new entrant to C# and OOP i am stepping into many little "details" that need to be addressed. Written a lot of code in VB.NET / cobol / simple php e.t.c surely does not help much into the OOP world... So , even after reading entry level books for C# and watching some videos i recently found out about the "factory model design" for applications. I would appreciate if any of you guys recomment some reading on application design architecture for further reading...

  • Goals for 2010 Retrospective

    - by Brian Jackett
    As we approach the end of 2010 I’d like to take a  few minutes to reflect back on this past year and revisit the goals that I set for myself at the beginning of the year (click here to see those goals).  I feel it is important to track your goals not only to see if you accomplished them but also to see what new directions in life you pursued.  Once we enter into 2011 I’ll follow up with a new post on goals for the new year. Professional Blog – This year I intended to write at least 2 posts a month.  Looking back I far surpassed that goal by writing 47 posts (this one being my 48th).  As with many things in life, quantity does not mean quality.  A good example is a number of my posts announcing upcoming speaking engagements and providing links to presentation slides and scripts.  That aside, I like to at least keep content relatively fresh on this blog  which I was able to accomplish.  At the same time I’ve gotten much more comfortable in my blogging style and it has become much easier to write. Speaking – I didn’t define a clear goal for speaking engagements, but had a rough idea of wanting to speak at 2-3 events.  Once again I far exceeded that number by speaking at 10 separate events and delivering 12+ presentations.  I’m very thankful for all of the opportunities that I was given and all of the wonderful people I have met as a result. Volunteering – This year I intended to help out with the COSPUG (now Buckeye SPUG) steering committee and Stir Trek conference.  I fulfilled both goals and as well as taking on lead organizer duties for the first ever SharePoint Saturday Columbus.  Each of these events and groups turned out to be successful and I was glad to be a part of them all.  I look forward to continuing to volunteer with each next year in some capacity. Android Development – My goal for getting into Android development was a late addition, but one I didn’t necessarily fulfill.  I spent a couple nights downloading the tools, configuring my environment, and going through some “simple” tutorials.  I say “simple” because in my opinion the tutorials were not laid out very well, took a long time to get running properly, and confused me more than helped.  After about a week I was frustrated with the process and didn’t think it was a good use of my time.  On a side note, I’ve dabbled in Windows Phone 7 development over the past few months and have been very excited by how easy and intuitive it was to get started and develop some proof of concepts. Personal Getting in Shape – I had intended to play on recreational sports leagues and work out on a semi-regular basis.  For the most part I fulfilled this goal by playing on various softball and volleyball leagues as well as using the gym.  At the same time I had some major setbacks.  In the spring I badly sprained my ankle and got hit in the knee with a softball which kept me inactive for almost 2 months.  More recently I broke my knuckle (click here to read about it) which I am still recovering from. Volunteering – On the volunteering front I kept my commitments at my parish’s high school youth group.  As for other volunteering opportunities I got involved with a great organization called Columbus Gives Back (website).  I’ve volunteered with them a few times and really enjoy their goal to provide opportunities to people with busy schedules.  They  offer a variety of events typically after work hours and spread out around Columbus with no set commitments on time you need to put in.  If you have the time or motivation I highly recommend them. House/Condo – I had been thinking of buying a house or condo this past summer, but decided to extend my apartment lease for another year instead.  I have begun the search for a place in the past few weeks and am excited begin the process of owning a home. Conclusion     This year I was able to set and achieve many of my goals.  For next year I’ll try to put more specific numbers to all of my goals.  If any of you readers set goals for 2011 feel free to send me a link as I’d love to see what you are aiming to accomplish.  Have a great end of 2010 and best wishes for the start of 2011!       -Frog Out

  • Confused about career options in Web Developement.

    - by Radheshyam Nayak
    I am currently in the final year of my graduation in computer science course. I love programming in PHP but not under pressure. As my graduation life is going to be over I have to shape up my career. My personal desire is to become a web developer and start my own web-based company after completion of courses. I do not have any desire to work for a company as a developer. Currently I have programming knowledge of PHP, Mysql and Javascript. Though I have not completed any type of project in PHP. So to become a complete web developer what else do I need to know to be able to get developement project? Any project I apply for are simply declined due to lack of portfolio. So how should I proceed?
