• Locomotion-system with irregular IK

  - by htaunay

  Im having some trouble with locomtions (Unity3D asset) IK feet placement. I wouldn't call it "very bad", but it definitely isn't as smooth as the Locomotion System Examples. The strangest behavior (that is probably linked to the problem) are the rendered foot markers that "guess" where the characters next step will be. In the demo, they are smooth and stable. However, in my project, they keep flickering, as if Locomotion changed its "guess" every frame, and sometimes, the automatic defined step is too close to the previous step, or sometimes, too distant, creating a very irregular pattern. The configuration is (apparently)Identical to the human example in the demo, so I guessing the problem is my model and/or animation. Problem is, I can't figure out was it is =S Has anyone experienced the same problem? I uploaded a video of the bug to help interpreting the issue (excuse the HORRIBLE quality, I was in a hurry).

• What is an acceptable GC frequency for a SlimDX/Windows/.NET game?

  - by Rei Miyasaka

  I understand that the Windows GC is much better than the Xbox/WP7 GC, being that it's generational and multithreaded -- so I don't need to worry quite as much about avoiding memory allocation. SlimDX even has some unavoidable functions that generate some amount of garbage (specifically, MapSubresource creates DataBoxes), yet people don't seem to be too upset about it. I'd like to use some functional paradigms to write my code too, which also means creating objects like closures and monads. I know premature optimization isn't a good thing, but are there rules of thumb or metrics that I can follow to know whether I need to cut down on allocations? Is, say, one gen 0 GC per frame too much? One thing that has me stumped is object promotions. Gen 0 GCs will supposedly finish within a millisecond or two, but if I'm understanding correctly, it's the gen 1 and 2 promotions that start to hurt. I'm not too sure how I can predict/prevent these.

• how to uninstall sphinx server

  - by misterjinx

  I installed (from sources) yesterday sphinx server and didn't think of configuring it properly, so I left the default installation directory (/usr/local). Today I realized that it created all of it's directories inside that directory, instead of creating its own (as I wrongly thought). So today I started again the installation and specified explicitly the location where to install. After that I removed the previous directories from /usr/local that were created when the first installation was done (bin, etc, var). So I thought of giving it a test. I created the .conf file and wanted to run the indexer. But now, the indexer always tries to search the .conf file in the old location (obviously does not find anything) and when I specify where to find the .conf file it gives me errors for each of the configuration settings present. I know I did something wrong when I deleted manually those files and that's why I'm asking you if have any ideas how to correctly uninstall sphinx. Thank you.

• username mapped to a different account

  - by Ubuntuser

  I had 4 accounts on UBuntu 11.10. The /home folder is in a separate partition. Now, after I reinstalled Ubuntu 12.04 beta 2, I manually created the remaining 3 usernames so that it can use the existing home locations. However, after creating the users i found that the usernames have got mapped to the other home folders. For example user A got mapped to home folder of user B User B got mapped to home folder of user C User C got mapped to home folder of user A How do I change this so that the users get mapped to their correct account.

• Ubuntu not booting from USB on laptop (no optical drive)

  - by Jamie

  I'm using a Kingston 16GB USB, with the Unetbootin program. (I've tried both downloading the installation iso manually and adding it, or using the program to download.) I've tried creating the bootable USB on an iMac, the laptop and also a desktop. I've booted into the setup of the laptop and changed the boot order to make sure it boots from that drive first. (There is no optical drive so that isn't a problem.) It's an Acer Aspire AS3810TZ. Upon booting it gives this message: SYSLINUX 4.03 2010-10-22 EDD Copyright (C) 1994-2010 H. Peter Anvin et al I get this no matter how I create the USB, it just sits there. I left the laptop for an hour and it hadn't moved. I've also tried on a different 4GB USB (Generic) and that did the same.

• Odds For Fighting Game

  - by thinkfuture

  I'm creating a fighting game where two opponents face off against each other in the ring. While I've been able to figure out the odds of a player winning based on previous wins/losses, I have yet to find a formula which modifies those odds based on opponent. For example: Player 1: W:5 L:5 - 1/1 odds Player 2: W:5 L:0 - 1/5 odds I want to calculate the odds that Player 1 will wins against player 2. Compounding this the players could be of different levels: if the players are within a few levels of each other, the odds should map closely to wins/losses. However, as the levels diverge, the odds of the lower level player winning reduce. As a swag: Player 1 - W:5 L:5 - 1:1 odds Against a level 8 - 1:2 Against a level 9 - 2:3 Against a level 10 - 1:1 Against a level 11 - 3:2 Against a level 12 - 2:1 These are just estimates, my sense is that there is a math formula out there which will calculate that - can anyone out there point me to what this could be? Thanks...Chris

• What's the recommended way of doing a HUD for an android game?

  - by joxnas

  Basically the question is in the title. I'm creating a RTS game and I will need buttons like attack move / attack ground, etc. I am not using any engine. When people do games in OpenGL for android (my case), do they ever use android components to control the game or do they create their components in the game? What are the general recommended approach, if there's any? How about more complex components like scrolling lists of items , etc? I would also appreciate you to pair your answer with a brief comment about how was your experience using the approach(es) you describe. Thanks :)

• What steps/tools/apps are necessary to make local php development on a tablet viable?

  - by Tchalvak

  I do my php web development locally, as in, creating a local instance of a site and then coding it and then pushing code to servers via git/github. I'm considering getting an android tablet or ipad and a wireless keyboard for very mobile development, but I in no way want to go back to the bad old days of using ftp and syncing up code changes on a development server directly, that would be too much of a trade-off to interest me. Is there enough support for the stack to develop php websites locally on a tablet? Anyone had experience trying this sort of thing?

• Useful versioning scheme for a git project?

  - by Oliver Weiler

  I have a small github project, which I need to add an option to to output some version number on the commandline. The problem is I have no idea how to "compute" the version number. Is this some random process? Should I just start at 1.0 (probably creating a tag or something), and put a number after . for fixes? I know this question is a bit vague... I just had never to deal with this, and want to use some sane versioning scheme. EDIT Im also interested into how to update this version number automatically, maybe using something like a git hook.

• Reminder: WebLogic Global, Virtual Developer Day November 5

  - by jeckels

  Just a quick reminder about the FREE virtual developer day focused on WebLogic (and Coherence) coming on November 5th. This day, with content tailored for developers, will guide you through tooling updates and best practices around creating applications with WebLogic and Coherence as target platforms. We'll also explore advances in how you can manage your build, deploy and ongoing management processes to streamline your application's life cycle. And of course, we'll conclude with some hands-on labs that ensure this isn't all a bunch of made-up stuff - get your hands dirty in the code!November 5, 20139am PT/12pm ETREGISTER NOW We're offering two tracks for your attendance, though of course you're free to attend any session you wish. The first will be for pure developers with sessions around developing for WebLogic with HTML5, processing live events with Coherence, and looking at development tooling. The second is for developers who are involved in the building and management processes as part of the application life cycle. These sessions focus on using Maven for builds, using Chef and Puppet for configuration and more.We look forward to seeing you there - don't forget to invite a friend!

• Copying an SSH Public Key to a Server

  - by Nathan Arthur

  I'm attempting to setup a git repository on my Dreamhost web server by following the "Setup: For the Impatient" instructions here. I'm having difficulty setting up public key access to the server. After successfully creating my public key, I ran the following command: cat ~/.ssh/[MY KEY].pub | ssh [USER]@[MACHINE] "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys" ...replacing the appropriate placeholders with the correct values. Everything seemed to go through fine. The server asked for my password, and, as far as I can tell, executed the command. There is indeed a ~/.ssh/authorized_keys file on the server. The problem: When I try to SSH into the server, it still asks for my password. My understanding is that it shouldn't be asking for my password anymore. What am I missing?

• Single responsibility principle - am I overusing it?

  - by Tarun

  For reference - http://en.wikipedia.org/wiki/Single_responsibility_principle I have a test scenario where in one module of application is responsible for creating ledger entries. There are three basic tasks which could be carried out - View existing ledger entries in table format. Create new ledger entry using create button. Click on a ledger entry in the table (mentioned in first pointer) and view its details in next page. You could nullify a ledger entry in this page. (There are couple more operation/validations in each page but fore sake of brevity I will limit it to these) So I decided to create three different classes - LedgerLandingPage CreateNewLedgerEntryPage ViewLedgerEntryPage These classes offer the services which could be carried out in those pages and Selenium tests use these classes to bring application to a state where I could make certain assertion. When I was having it reviewed with on of my colleague then he was over whelmed and asked me to make one single class for all. Though I yet feel my design is much clean I am doubtful if I am overusing Single Responsibility principle

• Can using an apt proxy (d-i mirror/http/proxy string http://mymirror) affect the installation of a .deb?

  - by Randolph

  I have been doing Ubuntu deployment using a preseed.cfg. After becoming comfortable with the packages being installed it was time to reduce download time and internet traffic by creating a mirror. I ended up doing a "partial mirror" using apt-cacher-ng and preseeding it by adding d-i mirror/http/proxy string http://mymirror to the preseed.cfg. This is where things got strange. I have a few .debs that I run as part of preseed/late_command by wgetting them and installing them with dpkg -i. The packages were installing without issue until added the proxy. With the proxy they fail to install. So does the proxy affect installing .debs during preseeded installation?

• Quickly and Python Twisted

  - by Aaron

  I am creating a Quickly application that makes use of Python Twisted. When the user launches a window, I want to start the Twisted server I wrote. However, when I do this, it freezes the GUI, because the reactor.run method is constantly running after it is started. I need a way to start the Twisted reactor in its own thread, so that the GUI will continue to operate while the reactor is running. I have read about using Twisted with pyGTK in the Twisted documentation, but I am not sure how I would accomplish this with a Quickly application. What is the best way to start my Twisted server when a window opens without freezing the GUI? Update: My if __name__ == '__main__' statement at the end of my dialog file is: print 'Preparing GLib' GLib.idle_add(before_running) print 'Staring Reactor' from twisted.internet import reactor reactor.run()` I have imported and installed twisted.gtk3reactor earlier on in the file. The before_running method contains dialog = ClientDialog() and dialog.show, as well as the rest of the code I want to run when the dialog opens.

• Resources for a fighting game

  - by David

  As the title says, I need resources for a 2D fighting game for the PC. The game is being made by me and two close friends. I'm thinking of using the FlatRedBall engine and either Allegro Sprite Editor or Amiga DPaint for the sprites, but I don't know is there is anything better for a more or less beginner in video game making. So my questions are as follows, what would be the best engine to use so that we could also sell the game later on, (I don't really care what language I'd have to use) and what would be the best thing to use for sprite creating? I would really appreciate any help given.

• SEO issue - External links rel="nofollow" or NOT!

  - by Mary Melody

  Previously I created a website for promo codes and coupons. That have hundreds of external links to the Retailer's websites and I used rel="nofollow" tag. But my site SEO rank was very very... bad especially on Google. So then I removed the rel="nofollow" tag, but no improvement. The only difference between this site and my other sites is "External links". My other sites have good ranking on Google. Now I'm creating a site for reviews. So this is also similar situation for me. I just want to know about how does SEO react with external links? and then what possibly happened in my case?

• iOS Game that Runs Continuously in Background

  - by user2913669

  I'm trying to understand the most logical way of creating an iOS game that runs continuously in the background. For example.. you have tower and enemy waves. The game has endless enemy waves even when the game exits. When you open the game again, it will retrieve the data that occurred when the app was closed. I assume a database on a server would be the best solution. The values continuously increment on the server. The game connects to the server and retrieves the specific user's updated game data.

• Are there compatibility issues opening Visual Studio Professional projects in Visual Studio Express, and vice versa? [migrated]

  - by theGreenCabbage

  Disclaimer: I have taken a look at the 50+ StackExchange forums to find the right place, and it seems /Programmers/ is the most suitable Exchange for this. If this is the wrong place to ask this, however, please let me know - I will personally delete the thread. I am in the process of downloading a single license for Visual Studio 2013 for my firm of 2-3 developers. One license is approximately $498.00 USD. As a small firm, our funds are short, but since we will be creating commercial software, we decided we will be needing the features of the Professional edition. At the same time, our decision is to use the Express edition for the rest of the two developers. My question is - will there be compatibility issues between Express projects and Professional projects for Visual Studio?

• why google ignore my links page?

  - by Yaniv

  I have a website, where im loading all the data via AJAX. since, google doesn't work with AJAX, and the ways to make it AJAX-friendly are a bit odd, i thought that by creating a links page, where it links, from server side, to all the links that im loading in ajax - will solve the problem. but unfortunately, that doesnt seem to work. google webmaster shows that even though my links page discovered, the content of it - the links - are totally ignored. I can only assume that google tend to ignore links in such pages. my question is - WHY?! and furthermore, how to overcome this. Thanks.

• Why does update-grub not find ubuntu 11.10?

  - by Klaynos

  I've recently installed ubuntu onto my laptop. With the intention of dual booting with windows 7. On installation Grub wasn't loading, the computer continued to boot straight into windows. I loaded a live cd, mounted the installed ubuntu partion (sda6) as /mnt/ and windows boot partition as /mnt/boot Following the second option here: http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7 Through its entirety, so creating a new grub.cfg file. chroot /mnt update-grub Did not find ubuntu, just windows 7 and the windows recovery partition. Thinking this might be a weird quirk that as I was in ubuntu (all be it a live cd) it might not list ubuntu I restarted. Grub loaded but ubuntu was nowhere to be seen. How can I add ubuntu with Grub2? I could have fixed this myself in old grub but I'm pretty much in the dark here. Thanks

• Calculating WPM given a variable stream of input

  - by Jaxo

  I'm creating an application that sits in the background and records all key presses (currently this is done and working; an event is fired every keydown/keyup). I want to offer a feature for the user that will show them their WPM over the entire session the program has been running for. This would be easy if I added a "Start" and "End" button to activate a timer, but I need to detect only when the user is typing continuously - ignoring all one-time keyboard shortcuts and breaks the user takes from typing. How in the world do I approach this? Is this even realistically & accurately possible?

• Questions Anyone?

  - by Kevin Smith

  I've been working with WebCenter Content for almost 9 years now and have a ton of topics rolling around my head that I'm sure would make excellent blog post once I find the time to write them up. Does anyone have any questions they would like answered? Like why does WCC do ...? How does this feature work? I can't seem to get this working? Post your question to the comments and if it is something on my list of topics I had planned on creating a blog post about I will move it to the top of the list.
