• Source code not matching uploaded HTML file

  - by benhowdle89

  I'm not sure if this is the right place to ask but i'm having a hugely frustrating problem with Coda and my website (i'm not sure which one is causing the issue) I'm using Coda to make changes to my website, Coda uses built in FTP to save changes to your web page. So when you hit Save, it uploads the new file. I've been using Coda for months and never had a problem until now. I am making changes in the html of my index.php and hitting save, it's successfully uploading the file but no changes are reflected in the source code in ANY browser. I even logged into cPanel on my website, ie. www.example.com:2082 and looked at the file - the changes have been made successfully. But the actual webpage in browser's source code, no changes?? I have tried adding which made no difference. Interestingly i make changes to style.css and the changes are instant. I have emptied the cache on all of my browsers but i'm still having an issue. Does this sound like a Coda problem or has anyone heard of such a thing?

• C++: calling non-member functions with the same syntax of member ones

  - by peoro

  One thing I'd like to do in C++ is to call non-member functions with the same syntax you call member functions: class A { }; void f( A & this ) { /* ... */ } // ... A a; a.f(); // this is the same as f(a); Of course this could only work as long as f is not virtual (since it cannot appear in A's virtual table. f doesn't need to access A's non-public members. f doesn't conflict with a function declared in A (A::f). I'd like such a syntax because in my opinion it would be quite comfortable and would push good habits: calling str.strip() on a std::string (where strip is a function defined by the user) would sound a lot better than calling strip( str );. most of the times (always?) classes provide some member functions which don't require to be member (ie: are not virtual and don't use non-public members). This breaks encapsulation, but is the most practical thing to do (due to point 1). My question here is: what do you think of such feature? Do you think it would be something nice, or something that would introduce more issues than the ones it aims to solve? Could it make sense to propose such a feature to the next standard (the one after C++0x)? Of course this is just a brief description of this idea; it is not complete; we'd probably need to explicitly mark a function with a special keyword to let it work like this and many other stuff.

• SEO & Multilingual: would be this a good practise?

  - by Younès

  I am currently making a bilingual website and I'd like to get nice SEO results of course. Here's my idea: The internal links would be composed of the "www" subdomain so that people can share links regardless of their language. Anyway, their language is determined by the HTTP_ACCEPT_LANGUAGE PHP variable. So, they would see http:// www.site.com/mydocument/123 in their adress bar and never see any links like "http:// fr.site.com/mydocument/123" or "http://en.site.com/mydocument/123" The user can always switch the page's language thanks to links in the footer. The switching language link would be : http:// fr.site.com/mydocument/123 , and clicking on it would change his language session and redirects the user to http:// www.site.com/mydocument/123 In case of a crawling bot: I read that if the HTTP_USER_LANGUAGE variable was missing then it's a crawling bot. So, in that case, we set the defaut language as English. Each page, as I mentionned earlier, has a link for another language: On the page: http:// www.site.com/document/1323, the link http:// fr.site.com/document/1323 can be seen by the bot and be crawled. What do you think about this practise ? Would I get good SEO results for each language ?

• How to set an old view? [closed]

  - by xan

  Possible Duplicate: How to revert to GNOME Classic? is it possible to change general view in Ubuntu 12.04 so it was like in Ubuntu 10.04? I really liked old one and really don't like new one. Things that are annoying me: menu on the left with large icons lack of workspaces icons in right bottom corner lack of menu: Applications, Places, System in left top corner menu like: file | edit | view | help resize and red cross is available in all applications at the very top of the pulpit, unless at the very top of the application window I know it may sound crazy, but that's all me, don't like changes despite that I know they are often good.

• Fix: Cant Change or Remove Visual Studio 2008 from DVD

  If you installed Visual Studio 2008 on a 64-bit operating system, you may have trouble when you try ad add or remove functionality by inserting the disk (or remounting the ISO image).  I believe this is because of the path used to install the 32-bit Visual Studio program.  When you run the setup.exe off of the disk, you get this: Clicking on Change or Remove Visual Studio 2008 brings up this dialog: But not long after it appears, it disappears to be replaced with: Microsoft Visual Studio 2008 Setup A problem has been encountered while loading the setup components.  Canceling setup. FIX: Use Add or Remove Programs Launch the Add or Remove Programs dialog in Windows, and find Microsoft Visual Studio Team System 2008 Team Suite ENU (or whichever SKU you installed).  Click Uninstall/Change.  From here you should be able to change your installed components of Visual Studio successfully: Thanks to Brendan for the tip!

• How to sync client and server at the first frame

  - by wheelinlight

  I'm making a game where an authoritative server sends information to all clients about states and positions for objects in a 3d world. The player can control his character by clicking on the screen to set a destination for the character, much like in the Diablo series. I've read most information I can find online about interpolation, reconciliation, and general networking architecture (Valve's for instance). I think I understand everything but one thing seems to be missing in every article I read. Let say we have an interpolation delay of 100ms, server tickrate=50ms, latency=200ms; How do I know when 100ms has past on the client? If the server sends the first update on t=0, can I assume it arrives at t=200, therefore assuming that all packets takes the same amount of time to reach the client? What if the first packet arrives a little quick, for instance at t=150. I would then be starting the client with t=150 and at t=250 it will think it has past 100ms since its connect to the server when it in fact only 50ms has past. Hopefully the above paragraph is understandable. The summarized question would be: How do I know at what tick to start simulating the client? EDIT: This is how I ended up doing it: The client keeps a clock (approximately) in sync with the server. The client then simulates the world at simulationTime = syncedTime - avg(RTT)/2 - interpolationTime The round-trip time can fluctuate so therefore I average it out over time. By only keeping the most recent values when calculating the average I hope to adapt to more permanent changes in latency. It's still to early to draw any conclusion. I'm currently simulating bad network connections, but it's looking good so far. Anyone see any possible problems?

• how do I fix ati driver issue

  - by Michael

  I have little knowledge about ubuntu, but I am learning. Recently, my ubuntu 12.04 required that I update. I noticed that it was updating xorg and other things, after the update I was asked to reboot. I did. now when I start that computer up, it cannot detect any display and refuses to boot from usb. I have no idea how to recover my computer. It simply starts in what is akin to the terminal program and ask for my username and password. After that, I can enter commands. The problem may be because I manually installed drivers by copy pasting from some instructional that I now have no idea where they are, but what it amounts to is that I "built" the drivers. They were working GREAT until this update. I did this because otherwise I was unable to have sound through my hdmi. After I hand built the drivers, they worked great. After this update Ka-blam! nothing... Also, I had okay-ed lots of update sources (though all of them [xorg and such] were the stable versions, not the unstable update sources) Please help and thank you in advance. (if this is posted incorrectly or misplace, please let me know what to do)

• Black login screen Ubuntu 12.04 if WGA cable pluged in on reboot

  - by Sulliwane

  I'm using Ubuntu 12.04.1, 64 bits, installed on a Z77 Pro4 (ASrock motherboard), crucial M4 SSD drive (sata 3), and intel i5 3570k (ivy bridge). I have this annoying problem : When I startup the computer, I get a CLI login prompt : At this moment, if I press enter, i get the usual CLI login prompt. If not, here is what I get : From now, if I login using CLI, i identify the lightdm processus, kill and start it : #ps -A | grep lightdm #sudo kill -9 1273 #sudo lightdm and miracle, these commands bring back the gui login screen. BUT It's very annoying as I have to repeat these steps at every boot, and the people using this desktop are not familiar with linux at all! So I tried to figure out the cause and here is what I found : If, when I shutdown the computer, the WGA cable is not pluged in, then Ubuntu will boot on GUI login screen without a glitch! But If the WGA cable is pluged in when shuting down, I will get CLI login prompt... Note 1: I installed linux kernel 3.4, but it hasn't solve the problem. Note 2: Is it linked to the new HD 4000 integrated graphic processor ? Note 3: If i boot on an USB stick (Ubuntu 12.04), NO problems ! Note 4: If booting on the SSD, when clicking "shutdown" button, the shutdown process never ends up (logout screen keep displaying and fans are still rolling). But if booting on USB stick, the shutdown action runs properly.

• help with migrating from Widows, x64 FGLRX, CPU load, Java and Minecraft

  - by joxer

  Im new to ubuntu, it is the second time i have installed it. This comp is Dell studio 1558. some specs: CPU- intel core i7 Q720 1.6GHz, GPU- ATI Mobility Radeon HD 5400 FGLRX- i've fallowed these instructions among inspecting many others, i have tried all of the variants mentioned in that tread before reverting back to the drivers supplied with Ubuntu ( through additional drivers ) which apparently seem to work best. i am testing them with minecraft as silly as it may sound. in 2 to 60 minutes the FPS drop from 70+ to somewhere between 0 and 5. while "fgl_glxgears" runs at between 400 and 800 FPS smoothly.. I am using oracle ( sun ) JRE6 to run minecraft, i have gotten it through a tutorial linked on oracle's website, i currently have no other version of java installed ( was worse when i had a few others here ). after closing the game Ubuntu is similarly slow, i've checked the CPU load using System Monitor and it shows one of the CPU's jumping to 80%~100% load at a time.. a reboot solves it. i realize my mess is up to me to solve but a hand is always appreciated. tyvm in advance.

• Grub problem - Command prompt

  - by RhZ

  Update: Thanks to all who helped. I gave up and am going to re-install. Not the end of the world, no files will be lost :-) This time will be backing up grub haha. Thanks again, I really appreciate the community's help on this. I was going along fine when the new pae kernel came down, and it had some bug where the sound was all messed up. So I used startup manager to choose the older pae kernel and rebooted. But startupmanager must have fuXXored my grub. When I re-booted, I get thrown directly into memtest and thats it. I tried to re-install grub using the live disc method that I found in many places. That changed something so I get a prompt and the message: "GNU grub version 1.99 ubuntu. Minimal BASH-like editing is supported. Type help for complete list." But then I tried the live CD fix again and now am back at the memtest... What can I do to get my system running again? UPDATE: Just to be clear,when I start up I get a blinking cursor in the top left, and the word 'ON' in the middle of the screen. Then, after a good minute or two, the memtest starts.

• I want to be able to use the unity menu with Citrix full screen

  - by porec

  I use Citrix Reciever at work, with both XenApp and XenDesktop. Many times at the same time. Since the unity Menu stil apeirs on the top anyway, I'd like to be able to use it. Now I can see it, but it doesn't work.. I have to either tab me out, (double clicking the ALT first)opening another program first, or move the mouse to the left, opening another program from the unity menu from the left, BEFORE I can use the menu on the top.. (my menu on the left side is in autohide mode, so I actually like it :)) For example. I use spotify for lisening to music, it apeirs on the top menu, but it doesn't react when it click it.. I have to move the mouse to the left, open another program, then move to the top an ask it to show spofity. If I open spofify from the left menu, it hangs.. (since its hidden, and I have to ask it to be open, not reopen the hole program..) Or If I want to lock the screen, I have to open another program, (i.ex. nixnote) before I can lock it) since the unity menu is "on the top" anyways, I don't see the problem that it should be able to control such things..

• Why is Ubuntu unmounting my primary hard drive?

  - by Twisol

  I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out? EDIT: It just happened again, and I heard a small little clicky sound from the hard drive about five seconds before things went south. I'm thinking I should start backing up ASAP. In response to a comment, here's the dmesg output: http://askubuntu.pastebin.com/uYGshBay Also, the SMART status says the disk has a few bad sectors, and the detailed data says there are 14. It says it passed the self-assessment though. Lastly, this doesn't seem to be happening when I'm on Windows. I recently re-enabled ureadahead (which I disabled ages ago because it was causing Ubuntu to hang at the startup logo), could that be the source of the problem? I've disabled it again to see.

• Run external application on markdown source in ikiwiki

  - by student

  Can I add a button to each wiki page in ikiwiki which launches an external application (on the client side) or script with the markdown code of the current page as input? Edit: I didn't realize that it might be complicated to do it on client side as Zenklys' answer suggested. So perhaps I should describe more concretely what I have in mind: I want to have two buttons: "Get LaTeX" and 2. "Get pdf". Clicking on "Get LaTeX should generate a LaTeX file and the browser should simply open or download that file. Analogously for the pdf. It would even be ok, to have a button "Generate LaTeX" instead, which generates the LaTeX code and changes after the generation to "Get LaTeX" which simply points to the LaTeX file. So it is not really necessary to do the generation of the files on client side. Would be ok, if this is done (on a temporary folder) on server side. For the LaTeX resp. pdf generation I want to use a custom wrapper script for pandoc, let's call it mymarkdown2latex resp. mymarkdown2pdf.

• Sorting for 2D Drawing

  - by Nexian

  okie, looked through quite a few similar questions but still feel the need to ask mine specifically (I know, crazy). Anyhoo: I am drawing a game in 2D (isometric) My objects have their own arrays. (i.e. Tiles[], Objects[], Particles[], etc) I want to have a draw[] array to hold anything that will be drawn. Because it is 2D, I assume I must prioritise depth over any other sorting or things will look weird. My game is turn based so Tiles and Objects won't be changing position every frame. However, Particles probably will. So I am thinking I can populate the draw[] array (probably a vector?) with what is on-screen and have it add/remove object, tile & particle references when I pan the screen or when a tile or object is specifically moved. No idea how often I'm going to have to update for particles right now. I want to do this because my game may have many thousands of objects and I want to iterate through as few as possible when drawing. I plan to give each element a depth value to sort by. So, my questions: Does the above method sound like a good way to deal with the actual drawing? What is the most efficient way to sort a vector? Most of the time it wont require efficiency. But for panning the screen it will. And I imagine if I have many particles on screen moving across multiple tiles, it may happen quite often. For reference, my screen will be drawing about 2,800 objects at any one time. When panning, it will be adding/removing about ~200 elements every second, and each new element will need adding in the correct location based on depth.

• Is there any way to facilitate switching windows in Ubuntu?

  - by Ivan

  I'm just a student who received my laptop from my uncle, who's a coder, so I'm still getting used to working with ubuntu. I recently upgraded ubuntu from an earlier version, and everything seems to be pretty great. The only thing is that when I open a program, or file, or whatever, it takes up the whole screen. I can only close it by going to the far top left of my screen, or by ctrl+W. Anyways, I find it really hard to switch between programs. For example I really like to have my windows that are open to be accessible by clicking on their icon at the bottom of the screen... Great when writing or researching. Anyways, I really just want to find an easier way to switch windows. Also, I used to love the way I could cube-rotate my screen, and just drag files from one desktop to another, with compiz. Now, its sort of like flipping a coin when I switch windows, is there any way to get my desktop cube back? And yes, I have enabled all the old settings I used to use with compiz. Sorry if what I'm asking is very basic, I know how to use a computer, I'm just not really familiar with the interface! Any help is greatly appreciated.

• Ubuntu 13.10, kernel 3.11 blank screen issue with hybrid graphics

  - by Lagerbaer

  On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce: *-display UNCLAIMED description: 3D controller product: GK208M [GeForce GT 740M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:d2000000-d2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:5000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64) I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions. This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen? Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10. When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it). Help, I'm all out of ideas. EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

• Assigning a script to a keystroke to toggle touchpad

  - by sodiumnitrate

  Since my default sony vaio shortcuts don't completely work in Ubuntu 12.04, I'd like to assign a script to Fn + F1, which toggles the touchpad on and off, so that the cursor would stop moving while I'm typing. Since I use a mouse and rarely need to use the touchpad, I don't want to use "disable touchpad while writing", which doesn't really seem to work anyway. I figured that using a script with the following command (this works, but I have to open up a terminal each time): xinput set-prop 12 "Device Enabled" 0 I have two problems at this point. One is that I don't know how to write this script so that it will toggle it off if it is on, and on if it is off. I know I should use an if statement but I don't know what value I should be checking to see if it is on or off. The second one is that I am having problems creating a new shortcut. I use System Settings - Keyboard - Shortcuts. I tried to add, to custom shortcuts, a new one by clicking the '+' sign. I named it Toggle Touchpad, and added the path to the executable script with the line above, by typing /home/irem/.toggletouchpad I have made it an executable with chmod. The problem is that when I click apply, and then click back on it to define the keystroke, it re-opens the dialogue. I cannot define new keys. (It says disabled on the right column of the entry). I have also tried xbindkeys, which almost constantly crashes. I'd prefer the system settings, if I can set the shortcut. I'd appreciate if anyone can help. Thanks.

• Questions before I revamp my rendering engine to use shaders (GLSL)

  - by stephelton

  I've written a fairly robust rendering engine using OpenGL ES 1.1 (fixed-function.) I've been looking into revamping the engine to use OpenGL ES 2.0, which necessitates that I use shaders. I've been absorbing information all day long and still have some questions. Firstly, lighting. The fixed-function pipeline is guaranteed to have at least 8 lights available. My current engine finds lights that are "close" to the primitives being drawn and enables them; I don't know how many lights are going to be enabled until I draw a given model. Nothing is dynamically allocated in GLSL, so I have to define in a shader some number of lights to be used, right? So if I want to stick with 8, should I write my general purpose shader to have 8 lights and then use uniforms to tell it how many / which lights to use? Which brings me to another question: should I be concerned with the amount of data I'm allocating in a shader? Recent video cards have hundreds of "stream processors." If I've got a fragment shader being used on some number of fragments in a given triangle, I assume they must each have their own stack to work on. Are read-only variables copied here, or read when needed? My initial goal is to rework my code so that it is virtually identical to the current implementation. What I have in mind is to create my own matrix stack so that I can implement something along the lines of push/popMatrix and apply all my translations, rotations, and scales to this matrix, then provide the matrix to the vertex shader so that it can make very quick vertex translations. Is this approach sound? Edit: My original intention was to ask if there was a tutorial that would explain the bare minimum necessary to jump from fixed-function to using shaders. Thanks!

• What is the breakdown of jobs in game development?

  - by Destry Ullrich

  There's a project I'm trying to start for Indie Game Development; specifically, it's going to be a social networking website that lets developers meet through (It's a secret). One of the key components is showing what skills members have. Question: I need to know what MAJOR game development roles are not represented in the following list, keeping in mind that many specialist roles are being condensed into more broad, generalist roles: Art Animator (Characters, creatures, props, etc.) Concept Artist (2D scenes, environments, props, silhouettes, etc.) Technical Artist (UI artists, typefaces, graphic designers, etc.) 3D Artist (Modeling, rigging, texture, lighting, etc.) Audio Composer (Scores, music, etc.) Sound Engineer (SFX, mood setting, audio implementation, etc.) Voice (Dialog, acting, etc.) Design Creative Director (Initial direction, team management, communications, etc.) Gameplay Designer (Systems, mechanics, control mapping, etc.) World Designer (Level design, aesthetics, game progression, events, etc.) Writer (Story, mythos, dialog, flavor text, etc.) Programming Engine Programming (Engine creation, scripting, physics, etc.) Graphics Engineer (Sprites, lighting, GUI, etc.) Network Engineer (LAN, multiplayer, server support, etc.) Technical Director (I don't know what a technical director would even do.) Post Script: I have an art background, so i'm not familiar with what the others behind game creation actually do. What's missing from this list, and if you feel some things should be changed around how so?

• How to mount private network shares on login?

  - by bainorama

  I've read all the existing entries I could find on using pam_mount but none of them seem to work for me. I'm trying to automatically mount shares on my local NAS at user login time. The usernames and passwords on my NAS shares match my local user name and password, but there is no LDAP/AD server. My pam_mount.conf has the following: <volume fstype="cifs" server="bain-brain" path="movies" user="*" sgrp="bains" mountpoint="/home/%(USER)/movies" options="user=%(USER),dir_mode=0700,file_mode=700,nosuid,nodev" /> When I login, I see the following in /var/log/auth.log: Oct 13 10:21:26 bad-lattitude lightdm: pam_mount(misc.c:380): 29 20 0:20 / /home/alastairb/movies rw,nosuid,nodev,relatime - cifs //bain-brain/movies rw,sec=ntlm,unc=\\bain-brain\movies,username=alastairb,uid=1000,forceuid,gid=1000,forcegid,addr=10.1.1.12,file_mode=01274,dir_mode=0700,nounix,serverino,rsize=61440,wsize=65536,actimeo=1 The folder /home/alastairb/movies is present but empty (can't see the files which are on the NAS in the respective share folder). In Nautilus, the share is shown in the sidebar under "Computer", and clicking on this takes me to the correct folder, but again, its empty. Any ideas as to what I'm doing wrong?

• PyQt application architecture

  - by L. De Leo

  I'm trying to give a sound structure to a PyQt application that implements a card game. So far I have the following classes: Ui_Game: this describes the ui of course and is responsible of reacting to the events emitted by my CardWidget instances MainController: this is responsible for managing the whole application: setup and all the subsequent states of the application (like starting a new hand, displaying the notification of state changes on the ui or ending the game) GameEngine: this is a set of classes that implement the whole game logic Now, the way I concretely coded this in Python is the following: class CardWidget(QtGui.QLabel): def __init__(self, filename, *args, **kwargs): QtGui.QLabel.__init__(self, *args, **kwargs) self.setPixmap(QtGui.QPixmap(':/res/res/' + filename)) def mouseReleaseEvent(self, ev): self.emit(QtCore.SIGNAL('card_clicked'), self) class Ui_Game(QtGui.QWidget): def __init__(self, window, *args, **kwargs): QtGui.QWidget.__init__(self, *args, **kwargs) self.setupUi(window) self.controller = None def place_card(self, card): cards_on_table = self.played_cards.count() + 1 print cards_on_table if cards_on_table <= 2: self.played_cards.addWidget(card) if cards_on_table == 2: self.controller.play_hand() class MainController(object): def __init__(self): self.app = QtGui.QApplication(sys.argv) self.window = QtGui.QMainWindow() self.ui = Ui_Game(self.window) self.ui.controller = self self.game_setup() Is there a better way other than injecting the controller into the Ui_Game class in the Ui_Game.controller? Or am I totally off-road?

• Working with Git on multiple machines

  - by Tesserex

  This may sound a bit strange, but I'm wondering about a good way to work in Git from multiple machines networked together in some way. It looks to me like I have two options, and I can see benefits on both sides: Use git itself for sharing, each machine has its own repo and you have to fetch between them. You can work on either machine even if the other is offline. This by itself is pretty big I think. Use one repo that is shared over the network between machines. No need to do git pulls every time you switch machines, since your code is always up to date. Never worry that you forgot to push code from your other non-hosting machine, which is now out of reach, since you were working off a fileshare on this machine. My intuition says that everyone generally goes with the first option. But the downside I see is that you might not always be able to access code from your other machines, and I certainly don't want to push all my WIP branches to github at the end of every day. I also don't want to have to leave my computers on all the time so I can fetch from them directly. Lastly a minor point is that all the git commands to keep multiple branches up to date can get tedious. Is there a third handle on this situation? Maybe some third party tools are available that help make this process easier? If you deal with this situation regularly, what do you suggest?

• Creating a steady rhythm for music-based game in XNA

  - by A-Type

  I'm looking to develop a game for Windows Phone to explore an idea I had which involves the user building notes into a sequencer while playing a puzzle game. The issue I'm running into is that, while my implementation is very close to being on-beat, there is the occasional pause between beats which makes the whole thing sound sloppy. I'm just not sure how to get around this inside XNA's infrastructure. Currently I'm running this code in the Update method of my GameBoard: public void Update(GameTime gameTime) { onBeat = IsOnBeat(gameTime); [...] if (onBeat) BeatUpdate(); } private bool IsOnBeat(GameTime gameTime) { beatTime += gameTime.ElapsedGameTime.TotalSeconds; if (Math.Abs(beatTime - beatLength) < 0.0166666) { beatTime -= beatLength; return true; } return false; } private void BeatUpdate() { cursor.BeatUpdate(); board.CursorPass((int)cursor.CursorPosition % Board.GRID_WIDTH); } Update checks to see if the time is on beat, and if it is, it calls the BeatUpdate method which moves the cursor over the board (sequencer). The cursor reports its X position to the board, which then plays any notes which are in that position on the sequencer. Notes are SoundEffectInstances, preloaded and ready to play. Oh, and TargetElapsedTime is set to 166666, or 60FPS target. Obviously totaling up the time and then subtracting isn't the most accurate way to go but I can't figure out a way to work within XNA's system in order to overcome this issue. This current system is just horribly unstable. Beats lag and fire too early and it's obvious. I thought about perhaps some sort of threaded solution but I'm not familiar enough with multithreading to figure out how that would work. Any ideas?
