  • Choosing a crossplatform for mobile development

    - by Mech0z
    I am creating a enterprise project and will develop the app for WP, Android and IPhone (Maybe also tablets) I have then done some research of what solutions are out there and have narrowed my choice down to 3 platforms (Due to my requirement to work with Bluetooth) The biggest requirement other than Bluetooth is the need to create good interfaces and module programming so its easy to maintain the whole solution, other than that I would like to use C# but its not a real requirement, but if the difference between 2 platforms is very small then it might tip the scale. Mono (MonoTouch, Mono for android) PhoneGap RhoMobile From my understanding then PhoneGap is not suited for business apps and I am not entirely sure why, but it seems like a platform made for speed rather than long term developement, not sure how true this is. RhoMobile is made for enterprice and might suit my needs, but not sure if its a good platform Anyone with insight that care to share their opinion Mono is C#, seems to be very mature and I found MvvmCross which should help organize the project

  • Trying to Organise a Software Craftsman Pilgrimage

    - by Liam McLennan
    As I have previously written, I am trying to organise a software craftsman pilgrimage. The idea is to donate some time working with quality developers so that we learn from each other. To be honest I am also trying to be the worst. “Always be the worst guy in every band you’re in.” Pat Metheny I ended up posting a message to both the software craftsmanship group and the Seattle Alt.NET group and I got a good response from both. I have had discussions with people based in: Seattle, New York, Long Island, Austin and Chicago. Over the next week I have to juggle my schedule and confirm the company(s) I will be spending time with, but the good news is it seems that I will not be left hanging.

  • Want to develop my own primitive physics engine, don't know how to start with it's high-level architecture. Suggestions?

    - by Violet Giraffe
    Few years ago I tried to make a simple 3D game - billiards. Completed like 50%, stuck with physics. Basically, I only need to calculate balls rolling over flat surface, but it would be nice to make something more flexible. I know all the formulas and laws (most of them, anyway). the problem is I have no idea of how to make good physics engine architecture-wise. I tried google and other forums but didn't find what I was looking for. The only suggestion was to look at open-source engine, but I'm not that good a programmer to make heads or tails out of it...

  • MS in Computer Science after BE in electronics

    - by Abhinav
    I am doing my 3rd year Bachelors in Electronics and Electrical Communication but from the first year I have been interested in Computer Science. But at that time it was just my hobby. But in second year when I joined robotics my love for computer science rose. I with my team came in top three in 2 National Competition (Technical fests of different IITs) where we used Image Processing, Hardware interfacing etc. But then I realised that Computer Science is not just about coding. I took many lectures from online free schools like Udacity, Coursera in subjects related to Artificial Intelligence, Building a Search Engine, Design and Analysis of Algorithm, Programming a Robotic Car, Programming Languages, Machine Learning, Software Engineering as a Service, WebApps Engineering, Compilers, Applied Crypotography etc. I also did some courses in Core and Advanced Java in my second year from training institute. I will also be taking course in Statistics, Databases, Discrete Mathematics from 25th June. Now I realized how vast is the field of Computer Science and how efficient you become on deciding algorithms and classifying problems into different subfields which have been thoroughly researched so you don't always do brute force thing or naive programming. Now this field has become kind of passion for me. Adding to the fact I am also doing my 6 months internship in software field in Texas Instruments where I am working on Automation and Algorithms. I also have some 5-6 good college level projects in Softwares and Robotics. I also like Electronics but only some fields like Operating System(this subject was there in Electronics also), Micro Processor, Digital, Computer Architecture, DSPs etc. I really want to pursue MS in some field of Computer Science. I am giving GRE in October/November. Till now I have good CG of around 9.4/10 and my 1 year in college is still left. Do I have any chance that some good University in US will consider me for MS in field related to computer science or Robotics. Also Can you suggest somethings that I can do during this 1 year to increase my chances for MS or should I apply for EECS(Electrical Engineering and Computer Science) and then I can shift more towards Computer Science as my major option. My main aim is to do Phd after Ms in CS if I am able to do that somehow. I know that I have to put much extra effort to understand things in MS than CS undergraduates but I will do that with my full dedication, also when I communicate with my college CS students or during my internship period I didn't feel that I am missing very much stuff that they know and was very comfortable during my internship with software employees.

  • Community to discuss project ideas

    - by Auxiliary
    Although I already predict the down votes but the question has stuck in my throat for a while now. I think this has happened to many of us. Sometimes we find a great idea for a project and obviously think this is THE GREATEST idea ever but then one of the following things will happen: The project is a small one, so you might actually give it a try and see how it goes. The project is a big one, even a risk, and you just need a good programmer's community that you could just discuss your idea with them and see what they say and even get some help to make it happen. And there's always the possibility of others stealing your idea which is really bad. So could anyone suggest an online community or place or even method of talking about ideas and the ways of developing them? and do you think it's a good thing to tell others about your idea?

  • Why everybody should do Sales!

    - by FelixWehmeyer
    I speak with many business students and ask them what job they want to get into. Most of them tell me they want a job in Marketing, Management Consulting or Finance. I hardly ever hear “Sales, that is what I want to do”, and I often wonder why. I would like to start with a quote from Zig Ziglar, a successful salesman: "Nothing happens until someone sells something." But to get back to the main point, why wouldn’t you want to get in sales? When people think of sales, they picture a typical salesman in their head and think that selling is scary and all about manipulating, pressuring and pushing someone into buying something they don’t need. Are these stereotypes accurate? I don’t believe so: So why should you want to be in sales? If you think about selling as providing the solution for the problem and talking about the benefits of making a decision, then every job in this world comes out of selling. In every job you deal with coworkers that you want to convince of your ideas or convincing your boss that the project you want to work on is good for the company.  These days, consumers and businesses are very well informed about services and products. When we are talking about highly complex products, such as IT solutions, businesses don’t accept your run-of-the-mill salesman who is pushing a sale. These are often long projects where salespeople have a consulting and leading role. Salespeople need to be able to consult companies and customers with their problem and convince a client that their solution is the best fit. Next to the fact that sales, is by far, not as scary and shady as you thought, there are a few points that will make you want to consider a sales career: Negotiating skills – When you are in sales you will learn how to negotiate. Salespeople learn to listen to their customers and try to make them happy, overcoming objections and come to a final agreement that both parties are happy with. Persistence/Challenge – As a salesperson you will often hear a negative answer, in a sales role you will start to embrace this and see a ‘no’ as a challenge not as a rejection. This attitude change can help you a lot in your career, but also in your personal life. You will become more optimistic and gain a go-getter attitude. Salary – As salespeople are seen as the moneymakers for the company, companies often reward their sales teams generously. Most likely in a sales role, you will receive a good basic salary and often you get nice bonuses on top of that based on your performance. Oracle is, for instance, the company that offers the highest average commission in the world. Further you can expect many other benefits as companies know that there is a high demand for good salespeople. Teamwork – Sales is a lot like having your own business, you are responsible for your own territory or set of clients. You are the one who is responsible for the revenue coming from that territory. So in order to gain revenue you will have to work together with many departments and people to make that happen. Every (potential) client could be seen as a different project, and you are the project leader. Understanding customers and the business – From any job that you choose sales will get you the most insight in the market. Salespeople are usually well-connected, talk with different customers and learn about the market and are up-to-date about all latest changes. Even if you want to change to a different role in the long run, you have a great head start as you understand the market and customers like no one else. Job security – Look at all the job postings out there. Many of them are sales-related. So if you want to have a steady job, plenty of choice and companies willing to invest in you, sales could be something for you.  Are you interested in exploring a sales career? At Oracle we are always looking for good sales professionals and fresh graduates who want to get into sales! For many languages such as Flemish, Dutch, German, French, Swedish and Norwegian (and more) we are currently looking for graduates who want to develop their career in Oracle. Please have a look at this article for the experience of a Business Development Consultant at Oracle in Dublin. Want to learn more about this job check out this link or send an email to jessica.ebbelaar-at-oracle.com!

  • How to manage product backlog/user stories

    - by Andrew Stephens
    We're about to start a new project using Agile (using TFS), and I have a couple of "good practice" questions regarding the product backlog:- When we first start adding users stories, is it a good idea to put them in (say) a "Backlog" iteration, or just leave their iteration blank? Obviously when the time comes to start work on a US it would be moved into the appropriate iteration backlog. When breaking an epic down into smaller USs, would I simply close the original epic, as it's no longer required? Or should I create the new USs as children of the epic? (it's then someone's responsibility to close the epic once all child USs have been completed). Lastly, should the product backlog list all USs regardless of status, or only those that have not been started (i.e in my proposed "Backlog" iteration)? I realise these questions aren't life-or-death, but it would be nice to know how other people manage their product backlogs so we can organise things properly from the start.

  • Big Oh notation does not mention constant value

    - by user883561
    I am a programmer and have just started reading Algorithms. I am not completely convinced with the notations namely Bog Oh, Big Omega and Big Theta. The reason is by definition of Big Oh, it states that there should be a function g(x) such that it is always greater than or equal to f(x). Or f(x) <= c.n for all values of n n0. My doubt is the why dont we mention the constant value in the definition? For example. lets say a function 6n+4, we denote it as O(n). but its not true that the definition holds good for all constant value. this holds good only when c = 10 and n = 1. For lesser values of c than 6, the value of n0 increases. So why we do not mention the constant value as a part of the definition.

  • Joystick acts as mouse; won't stop

    - by Shazzner
    Joystick acts as a mouse, even when I'm playing a game that uses a joystick so I get random mouse events going on. I plugged a joystick in to play Spiral Knights, also installed joystick and jcalibrate. Everything is working good, except by default the joystick moves the mouse around and the button activate mouse keys. Now normally this would be good behavior if I'm on a Myth-box or something, unfortunately when I play Spiral Knights with joystick input I see my mouse cursor moving in the back ground and when I hit a button it thinks I'm pressing right-click so it minimizes everything. Also it creates folders and probably deletes stuff. So, basically how the heck do I stop it from acting as a mouse?

  • Is there a command-line utility app which can find a specific block of lines in a text file, and replace it?

    - by fred.bear
    UPDATE (see end of question) The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :) UPDATE: ..(sub-update) My following comment about reasons when not use sed are only in the context of; don't push any tool too far beyond its design intent (I use sed quite often, and consider it to be invaluable.) I just now found an interesting web page about sed and when not to use it. So, because of all the sed answers, I"ll post the link.. it is part of the sed FAQ on sourceforge Also, I'm pretty sure there is some way diff can do the job of locating the block of text (once it's located, the replacement is quite straight foward; using head and tail) ... 'diff' dumps all the necessary data, but I haven't yet worked out how to filter it , ... (I'm still working on it)

  • Business Choices and Evony

    - by Robert May
    Recently, I’ve been playing a game called Evony, and I finally decided to quit the game and thought I should warn others who might be tempted.  I also find a lot of insight with this game as an example.  A few of the companies that I’ve worked with or worked for have been like this and they are NOT good places to be. Evony is a joke designed to milk as much money out of people as possible.  As a professional software developer who mentors teams on how to build better software, here's what I see: They obviously offshore all development and have little oversight over that offshore development, and they probably have a small team at that.  Evidenced by the poor grammar throughout the game. They're seeking to maximize revenue and pushing to do as little development as possible, which would mean a small team. They're horribly understaffed in the customer support department as evidenced by never replying to this forum and never responding to bug reports or help requests (I've had one open with no response AT ALL for over a month . . .) They have way inadequate testing, no CI, and probably no automated unit tests.  You can see this by the poor grammar throughout the game and the type of bugs that show up. They aren't following a formal development process (no Agile, Waterfall, or anything else) as evidenced by their lack of predictable release cycle and lack of visibility. I'm guessing that the internal code base is terrible, otherwise, there wouldn't be an "Age II" that had nothing more than a new visual interface and a few rule tweaks.  This is also evidenced by the itty bitty scope of bug fixes and their inability to really fix bugs. Their Architect sucks.  Really, 42k user is all you can handle on a single server?  Could you REALLY not come up with a better way to scale to handle users?  They've built isolated worlds, instead of a single continuous world. Back to milking people for money--to really progress, you have to spend money. All of this adds up to knowing, deliberate actions on the part of management.  They CHOOSE to do this (like AOL choosing to send more discs instead of improve quality). So, what can we learn? This game will never really improve, since the bosses don't care, they're only in it for the money. The game will never have good support.  Again, the owners don't care. Giving them money only perpetuates this scam (and yes, I've given them money, way too much money. :() They don't care if you quit.  There's a new sucker born every day. Don't EVER go to work for them.  I've worked both with and for people like this and the culture is NEVER good. Ah well. Technorati Tags: Evony

  • I want to master ASP.NET - What concepts should I focus on/What concepts do you most value?

    - by Josh
    I start a job this summer doing work in ASP.NET 4 (C#). I plan on working with some legacy code as well as MVC. I want to get a running start. I have good understanding of HTML/CSS/Javascript, and pretty good understanding of C# itself, Design principles, Design Patterns, and understand masterpages, basic MVC2, and code behinds for web forms. In your opinion what aspects of ASP.NET are the most important to master for web applications? What do you value most in your usage of ASP.NET? Do you have a recommendation for understanding the internals of ASP.NET itself?

  • Basic AI FSM - Handling state transition

    - by Galvanize
    I'm starting to study on how to implement game AI, and it seems to me that a very simple FSM for my Pong demo would be a nice way to start. My vision on implementing this would be to have a basic state interface and a class for each state, then the NPC would have an instance of the current state. The class should have an update method and directions on wich state to go next, depending on the event received. The question is: How do I handle this event? Should I have a regular addEventListener and a costum event system? Or should I check on update for the things that could change the current state? I'm feeling a bit lost, I feel I have a good grasp on the FSM concept but a good implementation seems tricky, thanks in advance.

  • How does PHP5 fare with the earlier versions of the language

    - by Pankaj Upadhyay
    Many times, I like to learn PHP for web development but been drawn back due to comments like the following :- (Comments are just for reference and does not invite Flame-war) "PHP is good but generates spaghetti code" "PHP is nice but Python is marriage material" "PHP lags stuff that you get in other languages like C# or JAVA" But for PHP5 i have seen some promising comments. So, What my question is how does PHP5 fare with the earlier versions of the language and is it good enough now to learn for web development. NOTE:- No comparison of PHP with other languages is sorted here. Please comment just on PHP and it's comparison with itself

  • Which ATI driver version did 10.04 use?

    - by Jack
    I have a trouble with ATI driver with Ubuntu 12.04 LTS. When I install ATI driver in Ubuntu 12.04 via "Additional Driver", then I can't shutdown Ubuntu, it showed blank (black) screen and my laptop still run. Sometimes, my screen like that: http://www.youtube.com/watch?v=U9_iygesbBM But when I install Ubuntu 10.04 and install ATI driver via "Additional Driver", it's very good and no trouble I've seen. It's sweet but 10.04 is old and is supported to 4/2013. So I want to know why Ubuntu 10.04 works good better than 12.04 with ATI driver (in my case)?

  • How to properly remove URL's from Google's index?

    - by ElHaix
    On some of our sites, we now have several thousand pages that dilute our website's keyword density. The website is an MVC site with SEO routing. If I submit a new sitemap with say only the 2000 or so pages that we want indexed, even though navigating to the diluting pages still works, will Google re-index the site with only those 2000 pages, dropping the superfluous ones? For example, I want to keep roughly 2000 of the following: www.mysite.com/some-search-term-1/some-good-keywords www.mysite.com/some-search-term-2/some-more-good-keywords And remove several thousand of the following that have already been indexed. www.mysite.com/some-search-term-xx/some-poor-keywords www.mysite.com/some-search-term-xx/some-poor-more-keywords These pages are not actually "removed" as navigating to these URL's still renders a page. Even though there are potentially hundreds of thousands of pages, I only want say 2000 to be re-indexed and retained. The others removed (without having to do these manually). Thanks.

  • Architecture for subscription based application

    - by John
    This is about the architecture of my application I think. I have a Rails application where companies can administrate all things related to clients. Companies can buy a subscription and their users can access the application online. Hopefully I will get multiple companies subscribing to my appplication/service. Thing is, what should I do with my code and database? Seperate app code base and database per company One app code base but seperate database per company One app code base and one database The decision I am to make involves security (e.g. user from company X should not see any data from company Y) performance (let's suppose it becomes successful, it should have a good performance) and scalability (again, if successful, it should have a good performance but also easy for me to handle all the companies, code changes, etc) For sake of maintainability, I tend to opt for the one code base. For the database I really don't know at this moment. So what do you think is the best option?

  • Why is Conway's "Game of Life" used for code retreats?

    - by blunders
    Code Retreat is an all-day training event that focuses on the fundamentals of software development. There's a "global" code retreat day coming up, and I'm looking forward to it. That said, I've been to one before and have to say there was a huge amount of chaos... which is fine. One thing that I still don't get is why the "Game of Life" is a good problem for TDD, and what good and bad TDD for it feels like. Realize this is a pretty open ended question, so feel free to comment.

  • What if you don't have code samples to give a prospective employer?

    - by lucks
    What do you do when you don't have any good code samples available when asked by a prospective employer? I like to consider myself a fairly capable developer but I can't share any of the software I've been writing for my company the last few years. Unfortunately, I haven't been able to find the time to put much work in my personal projects either. Basically, I don't think I can find any code samples that are a good representative of my skills that I can share. Any ideas? Thanks in advance.

  • How to edit Synaptics Touchpad values in Ubuntu 12.04? No xorg.conf file!

    - by Dave
    After I installed Ubuntu 12.04 got some issues with my touchpad. I reported the problem and finally today a guy replied here - https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/992330 It seems that the solution was good because I edited HorizHysteresis and VertHysteresis using synclient: synclient VertHysteresis=48 and synclient HorizHysteresis=48 To see if they were really edited I run into terminal synclient and just seen there the values I added. Everything is running perfectly till now. But after I restarted Ubuntu the values are gone and rolled back to default. A guy told me to edit the xorg.conf file but there is no xorg.conf file in etc/X11. Thanks and hope someone can give me a good solution.

  • Computer Science Fundamentals - Recommended books

    - by contactmatt
    Hey, I'm looking to see if anyone can recommend any books in fundamentals of computer science. I obtained my associates degree as a programmer/analyst a couple years ago and I know a good amount about programming on the .NET framework. I'm even certified on the .NET 4 framework as a web application developer. However, since I was only able to obtain my associates degree, I was deprived at my college on the low-level basics and operations of computers and basic computer science information. I'm really interesting in learning about the low-level operations of a computer and in programming (bytes, bits, memory management, etc.) Can anyone recommend any good computer science books for someone who is decently experienced in programming? Thank You
