  • How to get scripted programs governing game entities run in parallel with a game loop?

    - by Jim
    I recently discovered Crobot which is (briefly) a game where each player codes a virtual robot in a pseudo-C language. Each robot is then put in an arena where it fights against other robots. A robots' source code has this shape : /* Beginning file robot.r */ main() { while (1) { /* Do whatever you want */ ... move(); ... fire(); } } /* End file robot.r */ You can see that : The code is totally independent from any library/include Some predefined functions are available (move, fire, etc…) The program has its own game loop, and consequently is not called every frame My question is: How to achieve a similar result using scripted languages in collaboration with a C/C++ main program ? I found a possible approach using Python, multi-threading and shared memory, although I am not sure yet that it is possible this way. TCP/IP seems a bit too complicated for this kind of application.

  • How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

    - by Dokkat
    I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.

  • How to solve linear recurrences involving two functions?

    - by Aditya Bahuguna
    Actually I came across a question in Dynamic Programming where we need to find the number of ways to tile a 2 X N area with tiles of given dimensions.. Here is the problem statement Now after a bit of recurrence solving I came out with these. F(n) = F(n-1) + F(n-2) + 2G(n-1), and G(n) = G(n-1) + F(n-1) I know how to solve LR model where one function is there.For large N as is the case in the above problem we can do the matrix exponentiation and achieve O(k^3log(N)) time where k is the minimum number such that for all km F(n) does not depend on F(n-k). The method of solving linear recurrence with matrix exponentiation as it is given in that blog. Now for the LR involving two functions can anyone suggest an approach feasible enough for large N.

  • Lesser-known Github features that I'm missing out on with Bitbucket? [closed]

    - by Ghopper21
    I've been using Bitbucket for my small-team development projects, with the assumption that it is more-or-less a Github clone with pricing that is better for my situation and support for Mercurial (which I don't need). However, I'm seeing there are material-if-not-overwhelming differences, e.g. Github's appealing and useful branches page versus Bitbucket's overly simple branch drop-down list. This makes me wonder: what else am I missing out on? What are the lesser known Github features that folks like me using Bitbucket to save money are missing out on? EDIT: following closure, I've asked for advice on making this question productive over at meta. See here.

  • Starting small custom development company, type of niches to target?

    - by Rick
    This is kind of a new years thing for me as I want to be more entrepreneurial going forward with programming and this is kind of a general question for anyone who may share the same ambitions as me. I have experience with web programming and, although I work full time for a company doing programming, I have some freelance programmers that I work with / employ for small projects. I want to see about taking things to the next level as far as building a small company doing custom development. I'm just not sure how to figure out what niches to target as far as what type of apps to build as demos, etc. I was thinking mobile (maybe Android or Iphone) but am just curious if anyone has any advice / resources. A lot of "web development" seems to end up being just using a CMS like Joomla or Wordpress, for smaller sites, so I want to figure a way to steer clear of this crowd and find some opportunity with companies / entrepreneurs who actually need real programming development done to build apps. Thanks for any advice

  • Need to set up shared storage for Guest virtual machines that are running on a Xen host

    - by Sajith
    My environment: I am doing these things at home with the purpose of learning about virtualization techniques. My machine have quad core processor that supports Intel-VT and 8GB RAM. XEN is the virtualization platform. In short, all domUs are LVM based. Mainly I have two questions; I need to have shared storage for these VMs. Something like NFS / NAS / iSCSI etc. However, I don't know which one is the best solution. Therefore, can someone tell me which suits best? Please note that, this shared storage need to be accessed by the other physical machines in the network. How to implement the selected solution for question #1? Any tutorials / guidelines / ebooks will be a great help and highly appreciated. Thank you in advance :)

  • How do I pick up a new language quickly, given I know several others?

    - by Mark Trapp
    One type of question that keeps coming up on Programmers.SE is how to learn a specific language, given you know several others (usually through a lot of experience or education). In some cases, however, one might need to get up to speed quickly for a job, or for personal development, or even to check out a hot new platform. In your experience, what general strategies have you used to pick up a new language quickly? Are there specific aspects of a language you try to focus on when starting cold? What types of resources do you find helpful in this process?

  • How do I advertise for volunteers for my open source project

    - by Code-Guru
    I have found a couple of related questions here on programmers.SE: How/where would I best advertise my open source project, in order to maximize my odds of finding collaborators? Where to find open source volunteers? My question is slightly different because I am primarily looking for non-coders to help with a few things in my new open source project. In particular, I'd like one or more people to create an icon and other graphics and to work on a web site, wiki pages, and/or other documentation. My project is a front-end for a baseball card database. So reaching out to baseball card collectors might be useful. Other than that, I would just like anyone who would like to contribute in small ways to a modest project. Where are some good places to advertise and find non-coder volunteers?

  • How to log out with a command in a gnome-less environment?

    - by octosquidopus
    I installed various window managers (Awesome, dwm, etc.) from which I am not able to log out back to the login screen (gnome-session) in order to switch to another window manager. I need to reboot to do that, which is a waste of time. Question How can you log out via the terminal? didn't work.. dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.Logout uint32:1 ..neither did this: gnome-session-save --force-logout ..nor that: gnome-session-quit --force-logout they all returned: Failed to call logout: The name org.gnome.SessionManager was not provided by any .service files Is there a quick way to log out back into Gnome's session manager from a non-Gnome desktop manager using a terminal emulator? I know that CTRL+ALT+BACKSPACE can be configured to restart X, but I'm looking for the easiest way to log out.

  • Sass interface in HTML6 for upload files.

    - by Anirudha
    Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/11/04/sass-interface-in-html6-for-upload-files.aspx[This post is about experiment & imagination] From Windows XP (ever last OS I tried) I have seen a feature that is about send file to pen drive and make shortcut on Desktop. In XP, Win7 (Win8 have this too, not removed) just select the file right click > send to and you can send this file to many places. In my menu it’s show me Skype because I have installed it. this skype confirm that we can add our own app here to make it more easy for user to send file in our app. Nowadays Many people use Cloud or online site to store the file. In case of html5 drag and drop you need to have site opened and have opened that page which is about file upload. You need to select all  and drag and drop. after drag and drop file is simply uploaded to server and site show you on list (if no error happen). but this file upload is seriously not worthy since I have to open the site when I do this operation.   Through this post I want to describe a feature that can make this thing better.  This API is simply called SASS FILE UPLOAD API Through This API when you surf the site and come into file upload page then the page will tell you that we also have SASS FILE API support. Enable it for better result.   How this work This API feature are activated on 2 basis. 1. Feature are disabled by default on site (or you can change it if it’s not) 2. This API allow specific site to upload the files. Files upload may have some rule. For example (minimum or maximum size of file to uploaded, which format the site allowed you to upload). In case of resume site you will be allowed to use .doc (according to code of site)   How browser recognize that Site have SASS service. In HTML source of  the site, the code have a meta tag similar to this <meta name=”sass-upload-api” path=”/upload.json”/> Remember that upload.json is one file that has define the value of many settings {   "cookie_name": "ck_file",   "maximum_allowed_perday": 24,   "allowed_file_extensions","*.png,*.jpg,*.jpeg,*.gif",   "method": [       {           "get": "file/get",           "routing":"/file/get/{fileName}"       },       {           "post": "file/post",           "routing":"/file/post/{fileName}"       },       {           "delete": "file/delete",           "routing":"/file/delete/{fileName}"       },         {           "put": "file/put",           "routing":"/file/put/{fileName}"       },        {           "all": "file/all",           "routing":"/file/all/{fileName}"       }    ] } cookie name is simply a cookie which should be stored in browser and define in json. we define the cookie_name so we can easily share then with service in Windows system. This cookie will be accessible with the service so it’s security based safe. other cookie will not be shared.   The cookie will be post,put, get from this location. The all location will be simply about showing a whole list of file. This will gave a treeview kind of json to show the directories on sever.   for example example.com if you have activated the API with this site then you will seen a send to option in your explorer.exe when you send you will got a windows open which folder you want to use to send the file. The windows will also describe the limit and how much you can upload. This thing never required site to opened. When you upload the file this will be uploaded through FTP protocol. FTP protocol are better for performance.   How this API make thing faster. Suppose you want to ask a question and want to post image. you just do it and get it ready when you open stackoverflow.com now stackoverflow will only tell you which file you want to put on your current question that you asking for. second use is about people use cloud app.   There is no need of drag and drop anymore. we just need to do it without drag and drop it. we doesn’t need to open the site either. This thing is still in experiment level. I will update this post when I got some progress on this API.

  • Sending files via HTTP to web service

    - by Serguei Fedorov
    I am bit frustrated at the lack of information about this online. Here is the issue: I am in charge of creating a iOS application which sends sound data back and forth between the server and the app. The Audio is in small files and thus does not need to be streamed over, but rather it can be sent. Right now, I am using a TCP server I wrote to handle applications like this. However, I want to keep the system as simple as possible and writing your own server and client sockets can get a bit complex and leaves room for crashes. Overall it slows down development because I need to account for packet structure and other things. My question is, can I write an ASPX or PHP web service that lets me pass the files back and forth through GET or POST?

  • Do delegates defy OOP

    - by Dave Rook
    I'm trying to understand OOP so I can write better OOP code and one thing which keeps coming up is this concept of a delegate (using .NET). I could have an object, which is totally self contained (encapsulated); it knows nothing of the outside world... but then I attach a delegate to it. In my head, this is still quite well separated as the delegate only knows what to reference, but this by itself means it has to know about something else outside it's world! That a method exists within another class! Have I got myself it total muddle here, or is this a grey area, or is this actually down to interpretation (and if so, sorry as that will be off topic I'm sure). My question is, do delegates defy/muddy the OOP pattern?

  • What significant lost advances on side tracks should be revived in the main stream of software?

    - by C.W.Holeman II
    In reading Alan Kay's question on Significant new inventions I was coming up with answers that were not new ideas but old ones that have been passed by in the main stream. So, what significant lost advances that happened on a side track should be revived in the main stream of software? These would be ideas that worked well in their context but a different context appeared and became dominant the context, even though it lacked the idea. It maybe that in the new dominant context one just cannot do something or it requires great effort to be exerted.

  • How to avoid being forked into oblivion by a more powerful contributor?

    - by Den
    As recently reported here: Xamarin has forked Cocos2D-XNA, a 2D/3D game development framework, creating a cross-platform library that can be included in PCL projects. However the founder of the project that was forked says: The purpose of the MIT license is to unencumber your fair use. Not to encourage you to take software, rebrand it as your own, and then "take it in a new direction" as you say. While not illegal, it is unethical. It seems that the GitHub page of the new project doesn't even indicate that it's a fork in a typical GitHub manner, opting for an easily-removable History section instead (see bottom). So my questions are: Was Xamarin's action and the way the action was done ethical or not? Is it possible to avoid such a situation if you are a single developer or a small unfunded group of developers? I am hoping this could be either a wiki question or there will be some objective answers grounded on modern OSS ethics/philosophy.

  • Is there a good tutorial/book for creating a quiz app for iOS 5? [closed]

    - by NRUTA
    I am new to iOS development and looking to create a quiz application which will be for ipad, iphone and itouch. It will ask a question, text based, and have four possible answers. After you select an answer, the system tells you if you are right or wrong and provides an explanation. It provides the percentage of correct answers. I'm not sure how to go about creating this and wondered if anybody has read a book, seen a tutorial or could offer any advice that would explain this process? Thanks in advance for all of your help!

  • I cannot see the drives on my computer

    - by Joseph
    I'm a new Ubuntu user and I installed this Ubuntu 12.04 fromn a usb stick. It all went fine(I think) but as I notice, there are no drives shown on the menu. I tried some command in the terminal to see if the drives are available and yes, they are available. My problem is how to make these drives show up on the menu above. Sorry if this question is somewhat vague. (I removed the image because I am not allowed to add an image because I have insufficient reputation)

  • help bonding streaming rtp 3g

    - by enrique
    first sorry for contact me here. Recuro to you after reading all the material I found about it and so it does not get set. My question is: I can configure load balancing in any way out? I have a hub with 3 USB 3G modems, I got the 3 simultaneously connect with an upload speed of about 500kb in each approx. and a dynamic ip each. I do a unicast streaming with vlc rtp with a bandwidth of 1.5mb. Bone the sum of the three modems. I was searching on ifenslave, iproute. Then I found a draft vlc MultiCat. I understood that this could end, but configure it only moves a card. If I can help extend the information willingly. From now eternally grateful.

  • Sharing SCTP connection with multiple threads

    - by poly
    I have an application that needs to run in SCTP environment, I have a question in sharing the connection among multiple threads for packet receiving only, I've tried with the sctp_sendmsg and it worked without even locking the threads (is that been taking care of by the OS, in other words, is it thread safe to do that). I've tested many cases with the send and I can't see them out of sync. Anyway, back to the receiving, is it possible to create multiple threads and send each thread the sctp descriptor to start receiving messages? Do I need a lock here or is it ok without lock? I'm using C in linux.

  • Notifications not working in Gnome 3.4

    - by chazdg
    Notifications are no longer working in Gnome 3.4 but they are working in Unity. I have tried everything I can think of but I am stumped. To clarify, I am changing the theme using Gnome Tweak. Themes were obtained from various repositories including noobslab/themes and webupd8. As an example, when using the default theme adwaita, I get all notifications when using Rhythmbox as to what song is being played on an internet radio station. I even tried a different media player with the same result. When I change the theme, all I get is a media player Icon. Change back to default theme and all Notifications work fine. Notifications were working at first with all themes, but no longer. The question is how to get Notifications to work for all themes. They did for previous versions of Gnome-shell.

There are two links provided in the below question that are both fine,'except for one minor problem - I only know java! Is there an open source sports manager project? After some googling, I have been unsuccessful in finding a sports management game that is written in java. I am do not particullarly care about the type of sport, becuase I am mostly interested in mechanics. Does anyone know of any such projects or am I out of luck on java?
