• How to set-up my own cloud server?

  - by WMRKameleon

  I am a student, 17 years of age and wanting to access all of my files at greatest ease. i would like to have a system like this: Computer A, B and C are the computers on which I work and to which the files should be available. Server A is located in my room and I can install Ubuntu on it. What is the goal? I want to edit files on computer A (e.g.) and computer A should update the file on my server, afterwards the server should update the files on computer B and C. (The same goes for editing files on computer B, afterwards the server has to update the files on A and C.) How am I able to set-up a network like this? It is about music, movies, pictures, documents... Thanks for those who are going to reply!

• Good floor planner program?

  - by torbengb

  I'm planning to have a house built. I want to draw up some sketches on the computer, so I am looking for a program that can help me do this. It doesn't have to be a professional architecture tool; in fact that would be too complicated just yet (but maybe later on, for the detailed work...?). A simpler tool would be better. Features should include such things as ability to draw and move walls (not just using simple boxes), calculate room/floor area, add windows and doors, and the like. That's why Inkscape or OOo Presentation won't do. On Windows, a friend would just download a cracked professional architecture tool but that is not what I want to do. Suggestions?

• Enabling DHCP without being connected

  - by Joe Philllips

  I was installing Ubuntu server the other night and I was not able to hook up to the network while installing because I don't have a monitor for my desktop machines. I had to go into the living room and connect to the HDTV instead. This leaves me without network connectivity. When installing it asks how I would like to set up the network. I would like to enable DHCP but it tries to detect a gateway when I do this and obviously it doesn't find anything. It won't let me move on without setting up an IP manually at that point. Isn't there a way I can enable DHCP for the next time it boots up instead? Why the need for it right then and there?

• I want a trivial example of where MongoDB can scale but a relational database will have trouble

  - by Ryan Weir

  I'm just learning to use MongoDB, and when discussing with other programmers would like a quick example of why NoSQL can be a good choice compared to a traditional RDBMS - however the scenarios I come up with and can find online seem pretty contrived. E.g. a blog with lots of traffic could be represented relationally, but will require some performance tuning and joins across tables (assuming full denormalization is being used). Whereas MongoDB would allow direct retrieval from one collection to the same effect. But the response I'm getting from other programmers is "why not just keep it relational and then add some trivial caching later?" Does anybody have a less contrived example where MongoDB will really shine and a relational db will fall over much quicker? The smaller the project/system the better, because it leaves less room for disagreement. Something along the lines of the complexity of the blog example would be really useful. Thanks.

• How do I select Wireless radio portions in Ubuntu?

  - by Ryan McClure

  Bear with me, to be honest I have no idea what Wireless radio portions are.... At my school, I was told my the user support that the wireless network in my dorm uses 801.11 A/B/G/N. For some reason, the wireless in my room doesn't work. However, other buildings use only A/B/G, they say. In any other building, my wireless works fine. How do I tell my system to use the G portion only? (As requested by user support in the email I received). Here are the various logs/output requested: dmesg lshw -c network lsmod

• Which hosted chat solutions offer the following?

  - by David

  I am looking for a chat room solution similar to the one on StackExchange to facilitate more responsive communication between the contributors on Open-Org.com. My criteria are the following: No Flash (this rules out more than half) Full history (meaning that it is possible to access all previous conversation for future reference. Very customizable No ugly IRC stuff filling up the chat view (I do not want to see who joined an who left etc.) No private conversations possible (this is just not in the spirit of Open-org.com) A hosted solution with a reasonable price. These criteria are so different from this question, so this is not a duplicate question. The service which matches this the closest is Chatroll.com. However, at 199$ per month their prices are outrageous.

• Unable to install Nvidia drivers

  - by Tazzer

  a few days ago I installed ubuntu 11.10 on my friends computer. Despite all of our efforts we are unable to open the default unity and it will only open the 2d interface. I have been told in the IRC chat room that we need to install the graphics card drivers(nvidia geforce 420.) When I check the additional drivers app it doesn't show any to install. I tried installing the ones from the nvidia website but no luck, I also forgot to mention. I don't know if it means anything but he has a 64 bit computer and it is ubuntu 11.10 64bit.

• How to resize a /home partition in Kubuntu?

  - by Devon

  I was distro hopping for awhile in the past few months, so in order to keep all of my files secure, I made a partition of around 50 GB named Files to store all of my files in, and still have them for quick and easy access. However, now that I've found a distribution I'm comfortable with (Kubuntu 11.10), I would like to remove this partition, and have all of my files in my /home folder, in order to more easily deal with these files. I've moved all of my files in the partition to my /home folder (and still have plenty of room to spare), and now I'm trying to delete the partition and use the space for my /home folder. I can delete the partition just fine, however, I can't extend the /home folder into the unallocated space. Here's a screenshot of what I'm talking about. In order to change the size of the /home partition, I need to unmount it. But, I am unable to unmount it! How do I best extend the size of the partition?

• Sanity checks vs file sizes

  - by Richard Fabian

  In your game assets do you make room for explicit sanity checks, or do you have some generally expected bounds which you assert? I've been thinking about how we compress data and thought that it's much better to have the former, and less of the latter. If your data can exceed your normal valid ranges, but if it does it's an error, then surely that implies you're not compressing the data well enough? What do you do to find out if your data is compressed as far as it can be, and what do you use to ensure your data isn't corrupted and ensure it's an official release? EDIT I'm not interested in sanity checking the file size, but instead, how you manage your sanity checks and whether you arrange the excess size caused by the opportunity to do sanity checks by using explicit extra data, or through allowing the data enough file space (data member size) to be out of valid range and thus able to be checked merely by looking at the asset in memory after loading.

• Grub failure after cat removed USB drive

  - by user76270

  I had a perfectly working Ubuntu Server system with U12.4 and Server installed and was setting up the mail system. When I was absent from my computer room my cat (furry type) apparently got to play with a USB dongle on an extension cable and removed it. The system went berserk and now will not boot. I ran Ubuntu 12.4 on the install disk and the directory structure and every thing appears to still be on the drives. How do I recover the GRUB boot section without the system repartitioning everything and wiping everything else? Please I am a total newb when it comes to Linux errors and fixing them.

• How can I get Xubuntu's workspace switcher to show the proper sized desktop?

  - by Jennifer Jones

  I recently installed the Xubuntu desktop over my Ubuntu 12.04 installation, and have been customizing it to my liking. My laptop comes to class with me, and when it's not out of the room, it's usually connected to a second monitor. When I am not connected to the monitor, the workspace switcher shows that my windows are all inside about half of each workspace, but there's only one monitor connected. I'm looking for a way to get it to show workspaces that are reminiscent of this monitor's size and nothing more. Is there a way to fix that? I can attach a picture of the problem if necessary.

• Level and Player objects - which should contain which?

  - by Thane Brimhall

  I've been working on a several simple games, and I've always come to a decision point where I have to choose whether to have the Level object as an attribute of the Player class or the Player as an attribute of the Level class. I can see arguments for both: The Level should contain the player because it also contains every other entity. In fact it just makes sense this way: "John is in the room." It makes it a bit more difficult to move the player to a new level, however, because then each level has to pass its player object to an upcoming level. On the other hand, it makes programming sense to me to leave the player as the top-level object that is persistent between levels, and the environment changes because the player decides to change his level and location. It becomes very easy to change levels, because all I have to do is replace the level variable on the player. What's the most common practice here? Or better yet, is there a "right" way to architecture this relationship?

• How can I enable auto-switching HDMI sound on Ubuntu 12.04?

  - by João Ciocca

  I've just installed Ubuntu 12.04 on my Lenovo G550 notebook and decided to test the main thing I use it for, on Windows: watching movies and series on my living room TV. Plugged in the HDMI cable, screen auto-configured nicely - awesome. But the sound is coming through my notebook's speakers, instead of my TV. Searched for almost an hour on Google, found a couple of things - nothing that helped, though. Here are two links that made me sad: Another question on AskUbuntu "a better sounding world" post about HDMI On 2, David says that autoswitching was disabled... so how can I enable it?

• How can I reconfigure the nvidia proprietary drivers from the command line (ssh)?

  - by Mathieu Pagé

  I have a linux HTPC (running XBMC) in my living room. This morning I ssh'ed into the machine and did upgrade it to 10.10. When it finaly resarted it says something about running in low quality graphics and eventually returned to a command line login prompt. I ssh'ed in again and did a sudo reboot now. When it came back on this time the image is rapidly scrolling from the top to the bottom of the screen. I guess the installed driver doesn't quite work with the S-Video port on which the TV is connected. previously it was working right with the nvidia proprietary drivers. How can I install thoses without using the GUI tool that comes with Ubuntu?

• What are the most effective learning methods?

  - by BuckWoody

  After I got done speaking at the SQL Server 2008 R2 Launch Event yesterday I came back to the hotel room for a web-meeting with some of the other teachers at the University of Washington. As teachers we are always looking to improve the knowledge transfer to our students – and the Program Director found an interesting study that I thought I might share here. Below is an un-labeled chart showing the effectiveness of learning methods according to a recent study. At the top are the labels. (“Teaching” here means students teaching each other). Try the experiment we did: place the labels where you think they’ll go. I’ll post the completed chart tomorrow. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Daily standups- yea or nay?

  - by Fishtoaster

  How valuable (or not) do you think daily stand-up meetings are? If you're not familiar with it, this refers to a daily meeting often pushed by Scrum adherents (and some other general agile proponents). The idea is that you hold a daily meeting, timeboxed to 15 minutes, and in which everyone must stand (to encourage people to be to-the-point). In the meeting, you go around the room and each say: - What you did yesterday - What you plan to do today - Any blockers or impediments to your progress. Do you think this practice has value? Has anyone worked at a place that's done it, and what did you think?

• Grub Rescue Error: Unknown Filesystem

  - by James

  I was trying to dual boot Windows with Linux (linux installed first). I read that it was easier to do so if windows was installed first. So I tried to install windows, by creating a partition for it. There wasn't enough room on the drive so I tried changing the filesystem of my existing partition to support windows. Now whenever I try to start my computer I get the grub rescue screen. I've tried booting from CD and USB with ubuntu and also with windows, but nothing happens. I ran ls in grub rescue and got hd0, (hd0,msdos5), cd (with an install disc inserted), fd0, and fd1. However if I run ls on any of these I receive the error: unknown filesystem. Can anyone help me out?

• Make Interactive Story more Variable [on hold]

  - by Guest0343

  I'm creating an interactive story that allows users to make choices based on a story. However, it doesn't give users room to do much creatively on their own. They are bound by the script at the moment. I'm wondering if anyone can suggest any element I can add that might give users some personalization. I was thinking about maybe character editing, but that doesn't add too much. I also thought about a stats system where they can have certain attributes and stats they might earn, but I'm not sure how they might use those stats. Anything is helpful!
