  • going from closed-source to open-source [closed]

    - by mspoerr
    I am thinking of releasing the source code of my application (Freeware at the moment). It is written in C++ with VisualStudio 2008 and all used 3rd-party libs are free or open-source and platform independent. The idea to release the source-code is very old, but till now I did not want to show the code because I am not sure if it is nice/well designed (I am not a professional developer), but the application is growing and help would be very welcome, but I want to keep control... What do I need to consider? Is there any best practice for this scenario? The code itself is one thing, but there is much more like license, documentation, project settings, 3rd party libs, platform (Sourceforge, other?)

  • How to open directory in Guake from Nautilus

    - by Tinellus
    In Nautilus, I have upon right-clicking a directory, the option to open a Terminal with the prompt in the selected directory. I think this is very handy and I use it a lot. Now I would like to use Guake instead of the classic terminal. Is there a way to do this? I'm struggling with nautilus-actions. I can open Guake allright (i.e. it drops down from the top since it's permanently loaded), but the prompt isn't located at the directory of choice. In addition, it's one more mouseclick to open the terminal (if it would work), I would prefer a shorter way. Anyone any idea how to manage this? (or could this be a possible feature request?) Ubuntu 12.04, gnome-classic without Unity

  • PHP Development Environment (Host: Windows 7, Guest: Ubuntu)

    - by Kristian Leiws Jones
    Since editing files live from a remote server slows down development. I use XAMPP on windows to develop then run the web app's on a Linux server. However to avoid environment dependencies I'd like to mirror the live environment and the development environments. What I'm asking is running development server on Ubuntu inside VirtualBox whilst editing the source files via ftp/Dreamweaver is a good idea? If so, and I wanted to view the local website on the host OS (windows) how would I do this? does the guest OS have a LAN/Local IP address? I notice on windows "ipconfig /all" there are "tunneling" adapters which I assume is for VirtualBox, so I guess the guest OS has the same LAN/Local IP address? if so how would I view the websites hosted on the guest OS on the host OS? I'd also need to host FTP server on guest OS. Note: I need windows! I would love to use Linux all the way -.-

  • Poof and it’s gone - Internship @ Oracle Netherlands

    - by Tim Koekkoek
    We still remember the first day we walked in the office in September. The moment we walked into the big entrance hall and saw all those unfamiliar faces, we had no idea that we all had such diverse personalities, and still we all had a great time together. At the end of our internship we could all say we felt comfortable working at the office, playing “some” table tennis. Besides, it has been a great learning experience and we look back on a good time.  We made our own video and it shows you what some of us have been working on during our internship @ Oracle in the Netherlands.  If you are also interested in Oracle and what we have to offer, you can join our Live Google+ Hangout every Friday at 3 p.m. or visit http://campus.oracle.com.

    Hello, we have been developing a web application in asp.net mvc. we have scenarios where many actions on web page are dependent upon role of a specific user.

  • How do I do TDD on embedded devices?

    - by Darth
    I'm not new to programming and I've even worked with some low level C and ASM on AVR, but I really can't get my head around a larger-scale embedded C project. Being degenerated by the Ruby's philosophy of TDD/BDD, I'm unable to understand how people write and test code like this. I'm not saying it's a bad code, I just don't understand how this can work. I wanted to get more into some low level programming, but I really have no idea how to approach this, since it looks like a completely different mindset that I'm used to. I don't have trouble understanding pointer arithmetics, or how allocating memory works, but when I see how complex C/C++ code looks compared to Ruby, it just seems impossibly hard. Since I already ordered myself an Arduino board, I'd love to get more into some low level C and really understand how to do things properly, but it seems like none of the rules of high level languages apply. Is it even possible to do TDD on embedded devices or when developing drivers or things like custom bootloader, etc.?

  • Multi threaded game - updating, rendering, and how to split them

    - by CodeBunny
    From the StackOverflow post (it was recommended I move this): So, I'm working on a game engine, and I've made pretty good progress. However, my engine is single-threaded, and the advantages of splitting updating and rendering into separate threads sounds like a very good idea. How should I do this? Single threaded game engines are (conceptually) very easy to make, you have a loop where you update - render - sleep - repeat. However, I can't think of a good way to break updating and rendering apart, especially if I change their update rates (say I go through the update loop 25x a second, and have 60fps for rendering) - what if I begin updating halfway through a render loop, or vice versa?

  • Prevent service from starting

    - by Evan Plaice
    So, I do Arduino development on my system to program arduinos using the FTDI USB programming interface (if you have no idea what this means don't worry). The issue arises because the FTDI interface uses tty to communicate and it conflicts with one of the default ubuntu services. The default service in question is called brltty (which enables braille accessibility for people with impaired vision). Considering that I don't have any particular use for this service and it's annoying to stop it manually (using 'service brltty stop') after I restart my system... Where would I configure this (or any) service to prevent it from loading on startup? Note: I also have this issue with qemu-kvm conflicting with virtualbox.

  • Happy 3rd Birthday SilverlightCream!

    - by Dave Campbell
    Happy 3rd Birthday!     Yesterday (May 16) was the 'Birthday' of SilverlightCream, which started just after MIX in 2007 with a post "Interesting Silverlight posts today: Silverlight Control & Silverlight Pad". Too many good posts flying around led me to want to archive them, particularly since I was being aggregated at a new site Silverlight.net, and I could give some of that 'reach' to the community. Saturday's post was number 862, and as of that post, there were 5697 blog posts archived in the database all tagged up and searchable at SilverlightCream.com using the search page. The search needs to be better, and that's another discussion, but it does work. The blog didn't begin life as the SilverlightCream blog, as is obvious from the name, but once I realized people were following it closely, I've tried to keep the signal-to-noise ratio very high. I even secured another blog for when I just want to rant about something to keep that stuff out of this one :) If you've been around since MIX07 days you've heard all this, but after talking to some people at MIX10 I realized not everyone knows all the ways the information is presented, so I figured doing a post like this once a year probably isn't a bad idea :) I scrounge through an ever-growing list of blogs (right now sitting at 505) looking for good stuff. I try to spin through the list every day, but with the list growing that large, it's getting tough. I usually use it as a background task while working or watching TV. If I just sit and go through the blogs it takes about an hour. The list is long enough now that from time to time, I'll only get partway through it and have 10 to 13 entries, so I'll just stop there and go on the next day... I don't like to have more than 15 in any single post. It's all pattern recognition as in "seen that", "seen that", "that's new", etc... so if you're a blogger, look at a heading below for some comments about blogging from my perspective. When I see something new, I make sure you're not pulling a 'Mike Taulty' on me and dumping 6 or 8 new posts in one day :), and I tag the ones I want to review. If there's not a lot going on, I may just push the posts as I come across them. Some days there may be 60 posts in that 'to review' list! Some are non-Silverlight, some are essentially duplicates of others, some are demos, ads, new releases of something, session materials, etc. I push lots of material into a database at WynApse.com, and the "Tagged Posts" menu on the left sidebar there takes you to a tag cloud of (at this very moment) "9224 articles tagged 13915 different ways using 459 unique tags". There are links in there on Gibson guitars, Jazz Guitar instructional stuff, Ford F-250 links, and tons of technical and non-technical stuff I've been aggregating for about 5 years now. So when I decide to blog (or shoutout) something, I first push it into the database at WynApse.com. Then I tag it all up and push it into the database at SilverlightCream.com. Then it gets pushed to @SilverlightNews. For a little over a year now, we're tracking unique IP hits on posts launched from either the blog post or from one of the SilverlightCream.com pages, and the posts with top hits from unique IP addresses in the last 7 days are displayed in a 'Skim' page at SilverlightCream... and that page needs work as well. The Skim page and tracking was the brainchild of my buddy Michael Washington. What I blog/shoutout After some time doing posts, I decided there were things that probably have no need to be searchable, but are good information, so I post those as 'Shoutouts'. Eventually I also decided the Shoutouts should get posted to @SilverlightNews, and that's now taking place. Notes to bloggers Remember I said spinning throught the Big List-o-BlogsTM is pattern recognition... that means I don't spend a lot of time on any individual blog deciding if it has new content. If you're familiar with the term 'Above the Fold', then you're probably ok. If I have to scroll the page to see if there's something new, or wade through some maze of menus, I'm probably going to miss new stuff. Likewise if you only show the latest on the front page and make it a puzzle to find the rest of them, or if you make the titles and initial graphics almost identical to the previous article, I'll miss it. Another thing is name/brand-recognition. Far be it for me (WynApse) to comment on someone blogging with a pseudonym, but if you want to get get some recognition, you are going to want your name to be available somewhere. I can think right off the top of my head of a couple good blogs that I have no idea of the individuals' real names. I can pull that off a bit because I've been around so long almost everyone knows who I am, but if you're new to the blog-o-sphere, being able to be name-recognized is as important as getting your brand out there. Kick my tires Finally, stuff happens... I may hit the wrong key and delete your blog, or a post might slip past me and I not realize it's new because of the naming, and never blog it. If you think I missed something, send me an email or use the submit page at SilverlightCream.com. Some bloggers have figured out that if they submit (one way or another) to me, their posts will go out next. I try to honor anyone that takes the time to submit with a quicker 'Cream posting. Thanks! Finally, thanks to everyone that contributes to the community as a whole... the blogs, the videos, and the presentations. A special thanks to everyone that reads SilverlightCream, or follows @WynApse or @SilverlightNews. Keep it all coming, and... Stay in the 'Light

  • How to build a turn-based multiplayer "real time" server

    - by jmosesman
    I want to build a TCG for mobile devices that is multiplayer over the web (not local wifi or bluetooth). As a player plays cards I want the second player to see what is being played in "real time" (within a few seconds). Only one player can play at a time. Server requirements: 1) Continuously listens for input from Player 1 2) As it receives input from Player 1, sends the message to Player 2 I know some PHP, but it seems like unless I had a loop that continued until I broke it (seems like a bad idea) the script would just receive one input and quit. On the mobile side I know I can open sockets using various frameworks, but what language allows a "stream-like" behavior that continuously listens/sends messages on the server? Or if I'm missing something, what would be the best practice here?

  • finding high end software contracting jobs

    - by numerical25
    I've been contracting for about 3 years now. I am currently a contractor for a web firm. This is a hourly position. I want to find larger projects. I had read that some people are able to only do one or two jobs a year and be set on that. I want those types of jobs, and I want to hire people to take on these jobs as well, but I have no idea where to start. I highly doubt places like odesk post these types of contracts. Where can I find them? How can I make good money and live comfortably while working for myself?

  • Exporting .FBX model into XNA - unorthogonal bones

    - by Sweta Dwivedi
    I create a butterfly model in 3ds max with some basic animation, however trying to export it to .FBX format I get the following exception.. any idea how i can transform the wings to be orthogonal.. One or more objects in the scene has local axes that are not perpendicular to each other (non-orthogonal). The FBX plug-in only supports orthogonal (or perpendicular) axes and will not correctly import or export any transformations that involve non-perpendicular local axes. This can create an inaccurate appearance with the affected objects: -Right.Wing I have attached a picture for reference . . .

  • Understanding and developing web services

    - by Pankaj Upadhyay
    This question is in conjuction with How would you approach developing a Hotel Reservation System? The solution to a system with different interfaces(or clients i should say) is to go with developing a Web service and have other systems interact with it. I never had the requirement for developing a Web service so i am bit short on it. All i understand is that A web service is a system or application that performs some operations which may include modifying, sending or receiving data over a network using HTTP protocol. (Let me know if the understanding is wrong) Now, from the other question it's clearly understood that i need to develop a web service but i have no idea as to how should i go about it. My language of choice is C# and .NET Framework. Question:: How do we develop a webservice and which tools,technology and framework should i use for the same using C# language?? Question:: How can i interact with this from a desktop WPF application, Website and Mobile app

  • Can I use a genetic algorithm for balancing character builds?

    - by Renan Malke Stigliani
    I'm starting to build a online PVP (duel like, one-on-one) game, where there is leveling, skill points, special attacks and all the common stuff. Since I have never done anything like this, I'm still thinking about the math behind the levels/skills/specials balance. So I thought a good way of testing the best builds/combos, would be to implement a Genetic Algorithm. It'd be like this: Generate a big group of random characters Make them fight, level them up accordingly to their victories(more XP)/losses(less XP) Mate the winners, crossing their builds, to try and make even better characters Add some more random chars, emulating new players Repeat the process for some time, or util I find some chars who can beat everyone's butt I could then play with the math and try to find better balances to make sure that the top x% of chars would be a mix of various build types. So, is it a good idea, or is there some other, easier method to do the balancing?

  • Real-Time Strategy Gameplay

    - by Ahmad Alkhawaja
    I am working on building a HTML5 RTS game, and my current state is that I am building the Campaign mode of the game, and want to define the gameplay (The Scoring, Unit Behaviors/Attributes). I am searching for links/articles/books about how to define the gameplay, for me this: The scoring Figuring out levels of control (in any RTS game, there is units, individuals and squads) Unit action/attributes/properties point timing (how long it will take to play?) Achievements ..etc I want to see how they usually define these areas in RTS games, I expect to see general document discussing this concept that I can use to build the gameplay. Any idea? Is my question clear or I need to provide more details?

  • Micro QR Code Generator with minimal error correction

    - by Florian Peschka
    I am searching a Micro QR Code Generator that fulfills the following requirements: At least 20 characters encoded Minimal error correction (required to get the 20 characters stuffed in) I already searched google, but it seems all micro qr generators automatically use maximum error correction, which is very unhandy for my task, as we need the 20 characters completety. I can't use standard QR because there are certain requirements that need the code to be smaller than a certain dimension when printed... I hope someone can help me. PS: I'm not sure that this is the right board to post this question on, so feel free to redirect me to a better board if you have an idea. PPS: If nothing can be found and I'm forced to write one on my own: Where can I find detailed information on how to write a QR code generator?

  • How do I ask google not to index certain parts of my page?

    - by Gavin Mannion
    I was searching for an old review on my site today and I noticed that Google is indexing the headline text in my latest article list on every page that it appears, obviously I guess. The problem is if I search for my Dragon's Lair review specifically to my site like this http://www.google.co.za/search?sugexp=chrome,mod=9&sourceid=chrome&ie=UTF-8&q=site%3Alazygamer.net+dragons+lair+review Then it returns a ton of pages that aren't appropriate as they aren't related to the review at all. The reason why I care is that I have a second Dragon's Lair review that was posted years ago and now I can't find it. Is there a way to hint to google that certain text isn't relevant to the actual content on the page? is it a terrible idea?

  • Are CQRS/DDD/Event Sourcing and REST compatible?

    - by Robin Green
    REST seems to promote the idea of a canonical URL for a resource, and PUTing/POSTing back a modified representation of that resource in order to change it. However, with CQRS - Command Query Responsibility Segregation - one can theoretically have a completely different "API" for reading and for writing, which seems to conflict with the REST ideal of one URL for a resource, and no RPC-style "verbs inside the request body". DDD and Event Sourcing sometimes go together with CQRS, which is why I mention them in this question. So, can CQRS be used together with REST? Or is it against the REST way of doing things? What about DDD? And Event Sourcing? Can they be used with REST?

  • Developing iOS apps as web developer

    - by Keyo
    My Boss has sold a few 'iPhone apps' to clients, we are a web development shop. I have explained to him that I do not know the first thing about them, but it's such a powerful buzz-word and we need to meet clients expectations. I do have some experience in C, Java and Python which should help if I need to use objective-C. I have even done a few Android tutorials. These apps will more or less be HTML, in my mind they are not real apps, but faux apps which have the same functionality as the clients' websites. To me a real app is something that uses the phones hardware inputs and outputs, gps, accelerometer, speaker etc. What resources can I use to get up to speed iOS development and how to build apps in html. I have no idea where to begin.

    Trying to install eclipse, I get the following error: XXX:~$ sudo apt-get install eclipse Reading package lists... Done Building dependency tree Reading state information...

  • Online Advertising And Marketing Your Services?

    - by Zenph
    I have been working on freelance sites for a good 4 or 5 years, bending over backwards to build a decent portfolio and generate great ratings. I take huge pride in my work (web applications). I'm completely lost because when I think what would happen if I suddenly lost my freelance account it isn't a pretty picture. I have literally no idea where else I could advertise my services apart from google paid advertising. Any suggestions? I'd of course be more than willing to pay for marketing and such. I've been searching google for ages and can't find much advice on where to advertise to secure good clients for web development work. I say good clients because I mean actual business owners, not somebody else who is outsourcing to me (where do they find clients?). I'd appreciate any help.

  • Do professional software developers still dream of creating industry/world-changing apps?

    - by Andrew Heath
    I'm a hobby programmer. The absence of real world deadlines, customer feedback, or performance reviews leaves me free to daydream about having and implementing The Next Great Idea That Changes the World. Of course I'm aware I probably have a better chance of winning the lottery, but it's fun to imagine knocking out some fully-homebrewed app that destroys the status quo. I know many professional programmers have side projects, some for profit others not. I was wondering on the way to work this morning (non-IT boring work) if having to code for your food tended to dampen the dreaming? Does greater experience leave you jaded and more focused on the projects at hand? Not trying to be a downer, just interested in the mindset of the real software professional :-)
