• Adding a small slide when player releases left/right key

  - by Dave

  the aim is for the player object to slow down and stop instead of just stopping dead. The following codes works ok when the player is not jumping, but gets stuck in an object if the player is in the air when they do it. Left Key released event: if hsp = 0 exit; hspeed = -3; friction = 0.20; if obj_Player.hspeed = 0 { hspeed = 0; } Right key released event: if hsp = 0 exit; hspeed = +3; friction = 0.20; if obj_Player.hspeed = 0 { hspeed = 0; } and here's the horizontal collision code for interest: if (place_meeting(x+hsp,y,obj_bound)) { while(!place_meeting(x+sign(hsp),y,obj_bound)) { x += sign(hsp); } hsp = 0; } x += hsp; Any help would be much appreciated. Thanks.

• Ubuntu stops letting wired or wireless mice click through after a short while

  - by Jonathan Chan

  Hi! I have a very confusing problem that renders Ubuntu near unusable. Whenever I try to use any wired or wireless mouse with my Ubuntu 10.10 install, clicks stop going through - often times, this blockage of clicks happens in less than a minute. Sometimes no clicks are accepted, other times, clicks are accepted in certain windows and denied in others. The end result is the same, and I am forced to resort to using the keyboard to navigate. If anyone could help me resolve this problem, I would be very appreciative, as it would finally allow me to try Ubuntu. Thanks!

• Maya is lagging in a specific way...?

  - by Aerovistae

  My Maya installation worked perfectly. It is not my computer. Something caused it to stop working overnight, somehow. When I try to drag a vertex or something like that, it moves the vertex, but then I have to click like 3 times somewhere outside the mesh before the actual mesh will catch up and follow the vertex. Until I do that, it just stays as it was, with a floating vertex somewhere inside it or outside it. It makes modeling borderline impossible and completely infuriating. What ought to be happening is what we're all used to-- as I move the vertex, the mesh follows it actively, so I can see what it looks like at every given moment until I release the vertex in its new position. Other weird thing: this only applies to complex meshes, like a couple thousand faces. A simple cube works fine. What gives?? Anybody?

• How do I remove nitrogen back to Ubuntu's default wallpaper manager?

  - by jonalmeida

  I was using nitrogen when I using openbox, but now I'm trying to stop it from setting the wallpaper so I can use the Ubuntu default (i.e via the System Settings panel). What I've done so far: sudo apt-get remove nitrogen Removed nitrogen configs at ~/.config/nitrogen/ Checked to make sure that draw_background in /desktop/gnome/background was checked So far it still doesn't work. I can't right-click on the desktop, so I'm guessing that I've missed something to get Nautilus back to drawing icons on the screen. Any help is much appreciated. Thanks!

• XNA GameTime TotalGameTime slower than real time

  - by robasaurus

  I have set-up an empty test project consisting of a System.Diagnostics.Stopwatch and this in the draw method: spriteBatch.DrawString(font, gameTime.TotalGameTime.TotalSeconds.ToString(), new Vector2(100, 100), Color.White); spriteBatch.DrawString(font, stopwatch.Elapsed.TotalSeconds.ToString(), new Vector2(100, 200), Color.White); The GameTime.TotalGameTime displayed is slower than the stop watch (by about 5 seconds per minute) even though GameTime.IsRunningSlowly is always false, why is this? The reason this is an issue is because I have a server which uses stopwatch and it is faster than my client game. For instance my client notifies the server it has dropped a mine which explodes in one minute. Because the stopwatch is faster the server state explodes the mine before the client and they are out of sync. I don't want to have to notify the client when the server explodes it as this would use unnecessary bandwidth.

• SMS ad service for a php app.

  - by BandonRandon

  I am about to launch a website that allows the end user to get alerted as their bus approches the stop. The only problem was this is a little expensive as I'm paying about 5 cents per alert. I was thinking that if i added a short message something like "brought to you by acme co" at the end of the message I may be able to recoup cost without making my service a paid one. Anyone know of any SMS ad companies or how one would go about finding one. Google has failed me, probably searching for the wrong thing.

• How would I go about implementing a globe-like "ballish" map?

  - by rFactor

  I am new to 3D development and I have this idea of having the game world like our globe is - a ball. So, there would be no corners in the map and the game is top-down RTS game. I would like the camera to go on and on and never stop even though you are moving the camera to the same direction all the time. I am not sure if this is even possible, but I would really like to build a globe-like map without borders. Can this be done, and how exactly? I am using XNA, C#, and DirectX. Any tutorials or links or help is greatly appreciated!

• Blank desktop after login

  - by Alex

  Today my 14.04 updated itself not requiring a reboot. After a while I rebooted because of other reasons and then I was pleasantly surprised by a blank screen. I have tried everything I could think about including Reinstalled compiz, unity, ubuntu-desktop, xorg Reinstalled and then removed the nvidia driver So far nothing has worked. Except for one little thing: my cairo-dock is showing. And that's all. I tried with Unity doesn't load, no Launcher, no Dash appears, but none of the answers there helped me. I also tried removing my ~/.Xauthority file and it still doesn't work. Does anybody know what else I could try? UPDATE: sudo dpkg-reconfigure xserver-xorg sudo service lightdm stop sudo service lightdm start When I run that code and then login again the icons on the desktop are displayed but the menu and the launcher are still not there. Also, when I try to run an application from CTRL + ALT + F1 such as dconf reset -f /org/compiz/ it says Cannot autolaunch D-Bus without X11 $DISPLAY I can only run applications with export DISPLAY=:0

Which value of coin and striker makes it look like real carom?

• USB printer doesn't finish in 12.04

  - by 213441265152351

  I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. Any ideas?

• Aide On a Low Memory System

  - by Jason Mock

  I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2, mysql) during the aide run. Unfortunately, it seems like aide continued to use every available byte (including the space freed up from apache2 and mysql). Here's a graph from munin showing what happens when aide runs: Note the spike of memory usage, well into swap, when aide runs Any suggestions on tuning aide to not use so much memory, or is there an alternative to aide that doesn't behave this way?

• Major problem with Nvidia drivers

  - by user38580

  Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.

• I'm the .1x programmer at my company. How can I best contribute?

  - by invaliduser

  I work at a newly-minted startup of five people. We have a Ph. D in machine learning, a former member of the RSpec core team, and the guy who compiles the Git binary for OS X. That's just the employees; the founder has a Ph. D and was CTO for a multi-billion-dollar corporation before leaving to start a (successful) startup, and has now left that to start this one. We also might get a guy with a Ph. D in math. Aaaaaaaaand then there's me, college-dropout intern. I think I'm pretty smart and I'm reading non-stop, but the delta of experience, skill, and knowledge between me and my co-workers is just breathtaking. So put yourself in their shoes: you've got a bright young intern who has a lot to learn but is at least energetic. What would be annoying? What use would you hope to get out of him in the here and now? What would be pleasantly surprising if it happened?

• How can you write tests for Selenium (or similar) which don't fail because of minor or cosmetic changes?

  - by Sam

  I've been spending the last week or so learning selenium and building a series of web tests for a website we're about to launch. it's been great to learn, and I've picked up some xpath and css location techniques. the problem for me though, is seeing little changes break the tests - any change to a div, an id, or some autoid number that helps identify widgets breaks any number of tests - it just seems to be very brittle. so have you written selenium (or other similar) tests, and how do you deal with the brittle nature of the tests (or how do you stop them being brittle), and what sort of tests do you use selenium for?

• Canon Pixma MP150 printer stops before the job is done

  - by aserwin

  I have a Canon Pixma MP150. It's old but it still works well. The problem is that since I have been running Ubuntu 12.04 the printer exhibits odd behavior. Usually right at the end of a job, it will stop. The printing is done, but the printer is still "working" and it won't release the paper. If I pull it out and test the printer, it will start over and print the same job. Once I just let it be and about an hour or so later it finished with no problems. My question is, could the be an issue with the printer (it is old) or is it the drivers in Ubuntu? Any advice (or suggestions on debugging) would be greatly appreciated as I print a lot and don't really want to buy a new printer.

• Do hiring managers have a hard time accepting developers who have a "business look alike" personal app but are NOT entrepreneurs?

  - by shadesco

  Directly post graduation from University, I decided to build my own web app (Ease My Day) while waiting to get a job as a software Engineer. The reasons to build this app: Gain solid hands on software experience before hitting the job scene Providing a solution to a common problem Not sitting doing nothing while searching for jobs The app is Not an entrepreneurial tryout nor a business to be sold. Still throughout interviews I noticed that at the rate of 4 of each 5 interviews I pass through the app is being confused with a business and I am asked the same questions: Why did you build the business? Why do you want to stop the app? Do you want to sell the app? Knowing that I didn't build a business nor make any income from this application. Do candidates who take initiatives and like to craft their own apps on the side cause a red flag on the hiring manager's radar?

• How to say effectively to a manager that you missed the 'deadline' [closed]

  - by CyprUS

  Possible Duplicate: I cannot reach my deadline. What to do? My manager is a very deadline specific person. Even though I am a trainee, he insists on a deadline for every small assignment that he gives. Now it so happens that I miss the deadline. And boy, he doesn’t like that at all! So how do I say that i missed the deadline without inviting his wrath? How to stop getting into his bad books? P.S. I am not being lazy. Just that the assignments that he gives are not easy stuff, plus I am doing it in Delphi, which is new to me.

• DHCP won't start / subnetting

  - by user114371

  I recently changed the IP address on an Ubuntu 12.04 server I have in my lab, which is running isc-dhcp-server. After doing so and modifying the dhcpd.conf file, my dhcp service would not start. I basically used the same configuration, except I modified everything to use /25 scopes rather than /24. When I try to start / restart the service, I see the following: MY@ubuntuserver:~$ sudo service isc-dhcp-server restart stop: Unknown instance: isc-dhcp-server start/running, process 20918 It looks like it starts, but it isn't actually running and Webmin states that the DHCP service is not running. So my question is, does isc-dhcp-server support subnetting (CIDR) style scopes, or must they be class A / B / C scopes (doesn't seem likely)? I've double checked the interface reference (this is a VM with only one defined eth0 interface) and everything else I can thing of.

• Adding an existing Control Domain to a Server Pool

  - by Owen Allen

  I got a question about LDoms: "Is it possible to move a Control Domain built through Ops Center with pre-existing LDoms into a server pool? If so, do I need to delete and recreate anything?" Yes, you can do this. You have to stop the LDom guests, and then you can add the CDom to a Server Pool. If the guests are using shared storage, you should be able to bring them up in the Server Pool. If the guests are not on shared storage, you can use the Migrate Storage option to bring their storage in.
