• Scrum - how to carry over a partially complete User Story to the next Sprint without skewing the backlog

  - by Nick

  We're using Scrum and occasionally find that we can't quite finish a User Story in the sprint in which it was planned. In true Scrum style, we ship the software anyway and consider including the User Story in the next sprint during the next Sprint Planning session. Given that the User Story we are carrying over is partially complete, how do we estimate for it correctly in the next Sprint Planning session? We have considered: a) Adjusting the number of Story Points down to reflect just the work which remains to complete the User Story. Unfortunately this will mess up reporting the Product Backlog. b) Close the partially-completed User Story and raise a new one to implement the remainder of that feature, which will have fewer Story Points. This will affect our ability to retrospectively see what we didn't complete in that sprint and seems a bit time consuming. c) Not bother with either a or b and continue to guess during Sprint Planning saying things like "Well that User Story may be X story points, but I know it's 95% finished so I'm sure we can fit it in."

• Custom keybindings without gnome-settings-daemon

  - by Carlito

  I am using Ubuntu 12.04 (Fallback) and I am trying to slim it down, mostly for fun/learning experience. I killed gnome-settings-daemon because I set up my theming from elsewhere. But now some of my keybindings are lost. I think the windowmanager ones are still working, like Alt-Tab and switch workspace. But my mediakeys to change volume and my custom keybindings are not working anymore. Is there a different way to save custom keybindings? Do I really need to run settings-manager to setup my keybindings?

• Error while trying to dual boot Ubuntu alongside Windows 8

  - by Brian

  I recently purchased a new Toshiba Ultrabook that comes pre-installed with Windows 8. I'm trying to dual boot 12.10 with it and I have run into a problem with the installer. When I get to the page to pick the partitions I get this: No drives are listed and the only thing in that device drop down is /dev/sda. If I click Install Now or +/-/change I get an "Ubuntu has stopped working" error message. I'm trying to install off a 12.10 64-bit USB drive in UEFI mode, and I have tried it with secure boot both enabled and disabled with the same results. The hard drive set up is as follows: 500 GB main drive windows recovery (primary) EFI boot section (primary) Windows' partion (280 GB I believe) (primary) unallocated space I created for Ubuntu partition (200ish GB) another Windows recovery partition (primary) 12 GB solid state drive all unallocated space Could it be a problem with the number of primary partitions? I think I read somewhere about a max of 4.

• How do I query the gvfs metadata for a specific attribute?

  - by Mathieu Comandon

  A nice feature in evince is that when you close the program and later reopen the same pdf, it automatically jumps to the page you were reading. The problem I have is that I often read ebooks on several computers and I have to find were I was on the last computer I was reading the pdf. I think syncing these bookmarks in UbuntuOne would be a killer feature for people like me who read pdfs on different computers. By investigating a bit, I found where evince was storing this data, it's in the gvfs metadata and it can be accessed for a particular document by typing gvfs-ls -a "metadata::evince::page" myEbook.pdf Rather that querying a particular file, I'd like to query the whole metadata file (located in ~/.local/share/gvfs-metadata/home for the home directory) for any file where this particular attribute is set to some value. The biggest issue is that gvfs metadata and stored in binary files and we all know it's not easy to get something out of a binary file. So, do you know any way to query the gvfs metadata for some attribute?

• Right tool for the job(html5 vs silverlight)

  - by Jargo

  I have been tasked to develop a web based offer request application for bathrooms and I am asking opinions on which tool should I choose. I have narrowed options down to two (html5 and silverlight). Most of the application consists of basic UI elements that could be achieved with html4. However most challenging part is the design view for the bathroom. User first defines size of the bathroom by giving dimensions. When the dimensions are defined the application renders an empty bathroom floorplan and user can start dragging&dropping furniture on to it. Some furniture have rules where they can be dragged. For example sinks can only be dragged next to a wall. I know that this functionality can be achieved with silverlight but what about html5 ? I know that Canvas element can be used to draw graphics, but can it render the bathroom smoothly as user drags a piece furniture on it?

• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• How do I handle "Firmware file X not found" stopping bootup?

  - by John Baber

  I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with [ 19.931097] b32-phy0 ERROR: Firmware file "b43/ucode16_mimo.fw" not found [ 19.9311126] b32-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website. written on it This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash.

• FTP over ssh hangs on "Connection established: Waiting for Welcome Message"

  - by Siriss

  I have looked far and wide and have not quite found the answer. I am running ubuntu 11.10, openssh, and vsftpd. I am trying to configure my FTP to tunnel over ssh. My ssh connection works just fine and I can create the tunnel to my FTP port. When I go to use Filezilla to connect, it hangs at "Waiting for Welcome Message". I think it is an iptables issue, but I can't seem to figure out what needs to be changed. When I take iptables down, it connects just fine. I don't want to open any more external ports, just my one SSH port, and I can't seem to get it right on the internal port forwarding rule. I always end up opening it to the outside. I would love some help if anyone has any ideas and I hope I have made it clear. Thank you in advance!!

• Bluetooth mouse contstantly failes to reconnect after sleep

  - by Peter NUnn

  It seems the bluetooth subsystem shows some bugs after the upgrade to 13.10. It was working quite happily at 13.04. The bluetooth mouse I have, simply won't connect after the computer goes into any sort of sleep and has to be re-added each and every time. Sometimes the the entire bluetooth stack has vanished alltogether. What changed with the bluetooth between these versions, that may cause this? This is a fresh install of Kubuntu I'm using (bluedevil) no an upgrade, but the same hardware as 13.04 was happy on. I have reported this as a bug https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/124698 and added the link here as requested.

• Should I use parentheses in logical statements even where not necessary?

  - by Jeff Bridgman

  Let's say I have a boolean condition a AND b OR c AND d and I'm using a language where AND has a higher order of operation precedent than OR. I could write this line of code: If (a AND b) OR (c AND d) Then ... But really, that's equivalent to: If a AND b OR c AND d Then ... Are there any arguments in for or against including the extraneous parentheses? Does practical experience suggest that it is worth including them for readability? Or is it a sign that a developer needs to really sit down and become confident in the basics of their language?

• Website inheritance of ownership question

  - by Adrian Denham

  I paid for a web site for my motel business, then due to my landlord actions I was placed in a position to file for bankrupcy. I asked my IT manager and web developer to close down the web site for the business. He has since then sold my web site to the new owners. I took all the photos myself and I am in at least 4 of the photos on the site. There are no changes to the site as I left it and it now states that it is under the copyright on the new owners? I am not sure what I should do as this happen 10 months ago and I have just found this out. Thank you for your help, I am in Australia.

• Torrent clients suddenly stopped downloading

  - by Vasilis Baltikas

  A few days ago I noticed, that Transmission in my Ubuntu 10.04 machine suddenly couldn't download anything anymore. To overcome this I have uninstalled and reinstalled Transmission and tried downloading with other clients (Deluge, Vuze) well seeded torrents (ubuntu iso images for example) without success. On the same computer I have also installed Ubuntu 10.10 and Windows 7, which I rarely use. What makes the problem I encounter weirder, is the fact that downloading via torrents works fine in my Ubuntu 10.10 and Windows partitions but not in Lucid Lynx. Browsing the web for similar problems didn't give me answers. Any help would greatly appreciated.

• Square game map rendered as sphere

  - by Roflha

  For a hobby project of mine I have created a finite voxel world (similar to Minecraft), but as I said, mine is finite. When you reach the edge of it, you are sent to the other side. That is all working fine along with rendering the far side of the map, but I want to be able to render this grid as a sphere. Looking down from above, the world is a square. I basically want to be able to represent a portion of that square as a sphere, as if you were looking at a planet. Right now I am experimenting with taking a circular section of the map, and rendering that, but it look to flat (no curvature around the edges). My question then, is what would be the best way to add some curvature to the edges of a 2d circle to make it look like a hemisphere. However, I am not overly attached to this implementation so if somebody has some other idea for representing the square as a planet, I am all ears.

• horizontal line across screen at startup

  - by Debbie Poole

  I recently ran an upgrade from 12.04 to 12.10 and was using Nvidia current tested drivers and all seemed ok at first. Then suddenly every time I started the computer and shutdown, the graphical plymouth logo changed to text.The only changes I made to try to correct this issue were; sudo apt-get --purge remove nvidia-current nvidia-settings sudo apt-get --purge autoremove sudo apt-get clean sudo apt-get update sudo apt-get install nvidia-current and this made no change at all to the display. Then I read somewhere that Nouveau drivers may be the answer, so I installed them to use instead, and hey presto, the shutdown screen displays the Plymouth splash. However with startup, I get a stable purple screen, for a while, and than a thick black horizontal line appears, really ugly-looking, and then the loging screen appears to be ok. Can I correct the login screen same as the shutdown screen?

• Unity and games don't work on new Thinkpad T420

  - by Clay Smalley

  Here's my setup: Lenovo ThinkPad T420, brand new NVIDIA Graphics Card 4GB of Ram 128GB Solid State Drive Intel Core i5 Processor Given these specs, there's no reason games and Unity shouldn't be working. The strange thing is that both do work when I run from a live USB, but not when Ubuntu is installed to the hard drive. Is there something different with the 3D capabilities of running from the computer as opposed to running from the live USB? Edit: Some more information: When I log in for the first time when running from the hard drive, Ubuntu says "It seems that you do not have the hardware required to run Unity. Please choose Ubuntu Classic at the login screen and you will be using the traditional environment."

• Slashdotted web site seeks new home

  - by Arthur Edelstein

  I am maintaining a website that contains mostly simple html (just a little php). Normally the site receives only 4000 hits per month, but it was recently slashdotted by the New York Times (30,000 visitors and 30 GB in a day) and the web host provider (bluehost) throttled the CPU in response. This slowed down the website considerably. What web host providers would offer a more scalable solution? Ideally I would like a high-quality host that charges by the GB and can handle bandwidth to expand during sudden slashdotting episodes without a reduction in performance.

• 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?

• sun.com - SMTP 521

  - by alexismp

  reason: 521 5.0.0 messages are no longer accepted for sun.com It's been planned for a while now - sun.com email addresses are no longer accepted and no longer forwarded to oracle.com. So check you contacts and update old Sun email addresses. While this will probably cut down the spam for a number of us you may need the new stable email address - most Oracle email addresses use the same first.last @ oracle.com pattern (but there are a few homonyms in a company with 100k+ employees). If you need to contact us (TheAquarium), the email address is in the "Contact Us" section on the blog.

• How do I reset my Ubuntu user password?

  - by Myself

  I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

• What should I worry about when changing OpenGL origin to upper left of screen?

  - by derivative

  For self education, I'm writing a 2D platformer engine in C++ using SDL / OpenGL. I initially began with pure SDL using the tutorials on sdltutorials.com and lazyfoo.net, but I'm now rendering in an OpenGL context (specifically immediate mode but I'm learning about VAOs/VBOs) and using SDL for interface, audio, etc. SDL uses a coordinate system with the origin in the upper left of the screen and the positive y-axis pointing down. It's easy to set up my orthographic projection in OpenGL to mirror this. I know that texture coordinates are a right-hand system with values from 0 to 1 -- flipping the texture vertically before rendering (well, flip the file before loading) yields textures that render correctly... which is fine if I'm drawing the entire texture, but ultimately I'll be using tilesets and can imagine problems. What should I be concerned about in terms of rendering when I do this? If anybody has any advice or they've done this themselves and can point out future pitfalls, that would be great, but really any thoughts would be appreciated.

• Asking about deleted partition at boot

  - by Shawn Mitchell

  I have Ubuntu installed through Wubi. I also had another partition on my computer to try out the dev preview of Windows 8 aptly named Windows_8. After I was done playing, I deleted the Windows 8 partition and added the extra space back to my Win7/Wubi partition. Now every time I boot into Ubuntu, it tells me that it can't mount the partition and asks me if I want to recover or skip it. Is there a way to get Ubuntu to forget about this partition so I can skip this extra step in my boot? Thanks

• Restoring a hard drive

  - by Indian

  I had a laptop on which there was an AMD X2 display card. Suddenly this laptop went kaput. Incidentally the hard drive was safe. I had checked it using another machine. Further, I got this hard drive covered using an external USB HDD case. One day, while sleeping, this case fell down and since then I have not been able to restore the contents of the Hard Drive (rather could not find tools to recover contents from the hard drive). This hard drive had three partitions (a) NTFS (b) Linux (either ext4 or ReiserFS; I do not remember which one I had formatted in); and (c) Swap. How do I recover my contents?
