• Desktop sharing options for Ubuntu 12.04 with Unity

  - by Stefan Buynov

  I would like to be able to access my office Ubuntu 12.04 machine from home, from a Mac Mini with Mac OSX. I have a VPN and I am able to access my office machine over SSH, so connectivity is not a problem. I browsed other questions, and it seems that there are several options: VNC XRDP FreeNX (haven't heard this one before) Are there any other? I have been using Remote Desktop on Windows before, and I actually like it. Not sure how well is XRDP implemented. I also used VNC several years back, and I didn't like its performance back then - not sure if things have changed since then. As I said above, the machine I want to access is running Ubuntu 12.04, with Unity. And I am using Unity by choice - I really like it and would like to continue using it :) The client computer is running Mac OSX (Snow Leopard). Based on your previous experience what is the best setup for this environment?

• Sun & Moon Movement

  - by Thomas Mosey

  I'm creating a 2D HTML5 Canvas Game and am stuck on how to go about animating my Sun & Moon. The current setup is basically setting the moon at -1024 on the X-axis and the sun at 0 and animating them at 1 pixel a second. My canvas width is 1024 pixels and whenever the sun/moons X position crosses over the width of the canvas, it's X position is then set to -1024 to repeat the animation. What I am trying to do is get it to sync up with my day/night cycles. Each day is 10000 ticks long (A tick being added every frame) with Day/Night being 50% each (5000 ticks each). What I am trying to calculate is what I'll need to add to the X position of each per frame to get the sun from an X of 0 to 1024 after 5000 ticks/frames. Any help is appreciated.

• Cannot connect to windows share

  - by BCqrstoO

  I've been going through and pouring over resource for the past few hours and I cannot get my box to connect to my friends network drive. My friend doesn't use linux, but he's setup the network share like this: DPR:\\name\images and he's given me the username and password which I've verified is correct. It is located on 192.168.0.2 sudo mount -t cifs -o username=***,password=*** //name/images /media/name/ sudo mount.cifs //192.168.0.2/name/images /media/name/ -o credentials=~/name.credentials (I've confirmed that ~/name.credentials does have the correct credentials as well) Regardless of what I attempt I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I'm not sure what I'm doing wrong, but it's probably really simple and stupid. Thanks to any/all in advance. EDIT: I don't know if this helps, but I'm running Ubuntu 14.04.

• How much to charge for Wordpress installation?

  - by Jack Duluoz

  I know this isn't properly a technical question but I hope this is ok here. The question is simple: how much should I charge a customer for a Wordpress installation & configuration? Configuration simply means I have to install him a theme (which is not provided by me), various plugins and maybe edit some lines of code here and there to make the whole thing work fine. MORE INFO I don't do this for a living, I'm just doing this for this single customer. He told me he wants to customize some features of the blog which I think will require a bit of code editing, but these will be small modifications, because I already told him that more substantial modifications will be billed separately. I don't know exactly how long will this take, but probably just 1 day for the setup and some more days to adapt the blog to the customer requests which will eventually come up later

• Good PPA for ffmpeg

  - by teeks99

  Its annoying that the default ffmpeg in ubuntu's repositories is outdated and hobbled for legal reasons, however, there's a great page on the forums that walks you through building it from scratch: http://ubuntuforums.org/showthread.php?t=786095 (I also add in support for --enable-libdc1394 --enable-libgsm --enable-libopenjpeg --enable-libschroedinger --enable-libspeex when I build, which is nice, but not essential.) Anyway, I'm getting set to setup a computer lab running ubuntu for a multimedia class I'm teaching, and I was wondering if there was PPA out there that did something similar to what is available when building from scratch. The things I absolutely need from it are up-to-date libxvid, libx264, libfaac, and libmp3lame support plus the un-encumbered stuff (vorbis, theora, vpx). Is there a PPA out there that provides something like this?

• Google Analytics Campaigns Not Tracking E-Commerce

  - by Paul

  I am running email campaigns via MailChimp and tracking the success of my campaigns via Google Analytics. I can successfully see data being tracked for: Reporting > Conversions > Ecommerce (Receiving Data) Reporting > Traffic Sources > Campaigns (Receiving Data) However, I am not receiving any Ecommerce data for the individual campaigns: Reporting > Traffic Sources > Campaigns > Ecommerce (No data) So I see data like: Visits: 18,501 Revenue: $0.00 Everything I have read leads me to believe this should just "work" if Ecommerce is setup. Is there some additional action I need to take for this work? Any help would be appreciated!

• Tweaks to allows maximum number of users to login to ubuntu server.

  - by nixnotwin

  I use ubuntu server 10.04 on a fairly good machine, with 2.40 duel-core processor and 2GB RAM. My users login with ssh or samba. I have setup LDAP with PAM to sync user accounts between unix and samba. When I allowed about 90 users to login over ssh at once the server refused login for many users. I am using dropbear as ssh server. Even samba logins failed for many users. I need to allow at least 100 users to login at once. Is there anyway to do this?

• Running a startup program in terminal as sudo

  - by Brandon

  I need to run a python script in a terminal, myscript.py at startup (on Lubunt). This script requires root. I've setup a .desktop file that runs the following command: lxterminal --command="python /home/d/Jarvis/alarm.py && /bin/bash" The terminal window opens at startup and runs the script, but then closes when the Python script returns an error (because it's not being run as root). When I change the Exec= to this... lxterminal --command="sudo python /home/d/Jarvis/alarm.py && /bin/bash" ... (prefixing command with 'sudo') which works. However, the terminal opens on startup and displays the [sudo] password for d: \ prompt, requiring me to input my password. I would like the execution of the python script at startup to be completely automatic with no user interaction. How can I accomplish this?

• Which programming language suits a system that must work without user input

  - by Ruud

  I'm building a prototype of a device that will function much alike a digital photoframe. It will display images retrieved from the internet. The device must start up and run the photoframe. It will have no user interface. The device has a minimal ubuntu installation, but I could install Xorg or whatever needed. Question: I have trouble figuring out which programming language will be suitable. I've just started using Python to try out several things and I am able to download and display images. I guess that means Python can do what I'd like, but is it suitable as a language that will be run on boot without any user interference? Related questions: - How do I set up Linux to start that script automatically? - How to setup a second Python script as a server that runs in the background to retrieve images before they are displayed (Because I think I'll need threading of some sort?)

• Where do my programs get installed?

  - by Micah

  Coming from windows I'm used to having everything installed in c:\program files\company\product. On Ubuntu I'm totally stumped. It seems like everything I install winds up somewhere different. Somethings are in /bin some in /home/myuser and others in /etc or /usr. I can't seem to figure this out. In particular I'm trying to find where they're located so I can either setup shortcuts on the task bar or associate them with other programs (like my greasemonkey editor) but I'm not having any luck.

• Why does my computer just keep restarting while trying to install Ubuntu 13.04 (x86) from USB alongside Windows 7?

  - by Sumit Chahal

  I have checked the other questions, but none of them match my problem (the ones that do don't have satisfactory answers). I downloaded the Ubuntu 13.04 iso and burned it to my USB device following the given instructions. I was also able to boot the Ubuntu setup from it by changing the boot sequence so that the USB device is now at the top. But I am only able to use the "trial" version of Ubuntu. Every time I tick "Install Ubuntu alongside Windows" and click "Continue", the computer just restarts and I see the same Try-Ubuntu-or-install-it menu. I have tried pressing any key when that little icon appears at the bottom, but it is not at all helpful. I also read somewhere that I should eject my USB device after I click "Continue", but doing so just makes the computer run Windows 7 instead.

This week we’re interested in hearing all about your media arrangements: Do you have a traditional cable bundle? Ditched it for a Netflix-only experience? Pay for both because you just can’t get enough of live TV and streaming content?

• Why is my Quickly app full of fail?

  - by bstpierre

  I tried to use quickly on Ubuntu 12.04 to create an application, but it does not behave as described in that linked page. I don't get a popup when creating the application (see error below). % quickly create ubuntu-application foo Creating project directory foo Creating bzr repository and committing Launching your newly created project! (foo:16847): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Congrats, your new project is setup! cd /tmp/foo/ to start hacking. It creates a project, but when I try to run, it crashes and burns: % cd foo % quickly run (foo:22639): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Is this because I'm not using gnome-shell? What can I do to get a working project? (Edit: As a side note, I'd be willing to debug this myself, but I don't even get a traceback. What do I have to do to get quickly to give me a traceback?)

• Find visitors to multiple subdomains on single visit with Google Analytics

  - by mrwweb

  I'm working on a site that has quite the backlog of Google Analytics data for their site network. One of our big questions is whether people enter on one site and move to another (and if so, of course, how do these visits differ from single site visits). The hostname report (Audience Network Hostname) shows all the host names and I've setup Advanced Segments to get site-specific data. That all works great, but I'm really having a hard time figuring out how to find visits to multiple sites as defined by visiting more than one subdomain or the root site and one or more subdomains. I do see that other hostnames somehow come through when I apply one of the segments to the host name report. Which I can't say I expected. Is that the best way to see if people are visiting 2+ sites?

• How can I reduce the time taken to login by postponing/delaying some startup applications?

  - by koushik

  I have setup some applications to startup on each login (e.g., redshift-gtk, gtg) automatically but after adding these to startup applications (System -> Preferences -> Startup Applications) obviously the time taken to login has increased. Due to all this the time it takes for my panels, desktop etc to appear is too long - until which I am forced to wait. I don't need these apps to be available immediately, but it would be good if they startup eventually, meanwhile the ubuntu menu/panel is available for running other apps that I might need to. I tried using at command, with the intention of editing all startup applications to put the commands in the at queue, but this didn't work since the apps don't get the necessary environment variables (like DISPLAY). Is this what nice command is used for? Any other ideas how I can accomplish this? If possible, I would like to avoid editing the startup applications commands, since this would mean a lot of effort to replicate on other machines I use.

• IP/PORT forward requests to another server

  - by DT.DTDG

  I have the following listening PORT:IP set up on my UBuntu server. 12.345.67.890:3636 It receives requests perfectly, however, I would now like to forward any requests to that IP:PORT to another IP:PORT, i.e.: 09.876.54.321:3636 Essentially I want to do a request forward 12.345.67.890:3636 -> 09.876.54.321:3636. How can I go about it in Terminal and if I wanted to change it back how can I go about that too? Is there also a way to test that the data is forwarding and it is setup properly? Thanks! Edit: Can I just do as follows, just wondering how I would go about testing it and how I could disable it? sysctl net.ipv4.ip_forward=1 iptables -t nat -A PREROUTING -p tcp --dport 3636 -j DNAT --to-destination 09.876.54.321:3636 iptables -t nat -A POSTROUTING -j MASQUERADE

I would preffer a solution similar to NSIS scripts.

• Backing up bind mounted folders

  - by NahsiN

  My layout is as follows. LVM Setup: /dev/VG/Documents, /dev/VG/Music, /dev/VG/Pictures, /dev/VG/Music, /dev/VG/Documents, etc.... Each of the LVMs is bind mounted to the corresponding folder name in /home/foo. For example, /home/foo/Documents bind mounted to /media/Documents (mount point of /dev/VG/Documents), etc. If I set up deja-dup to just back up my home folder, am I guaranteed that everything from my LVMs will be backed up properly? So let's say I take away my LVMs for some reason and choose to restore an earlier backup. My home folder will contain everything from the LVMs? All my docs, music, vids etc. My intuition tells me everything will be fine but it doesn't hurt to ask the the experts ;). Hope I have made myself clear. Thanks

• Why does my RAID configuration with mdadm fail on reboots?

  - by Andy B

  I have been running Ubuntu server on my machine for 2 years and it has worked ok. I would like to speed it up by raiding a few drives. The machine is used to host my Mysql databases internally. using MDADM raid.. I have tried 2 schemes so far with the 3 drives. 2 partitions on each drive 1 for the swap 1 for the O/S both of them turned into drives raid level 5 3 partitions on each drive 1 for the boot 1 for the swap and 1 for the root. The boot I set to raid level1 and the swap and root raid drives were set to level5 Both setup worked fine for about a week, then on a reboot things fall apart. by fall apart I mean I end up with a bunch of hard drive errors on the screen and then get a grub prompt. Why do they fail on reboots? I am eager to understand what I am doing wrong thanks!

• Random freezes on MBP9,2 + Ubuntu 12.04

  I have a MBP9,2 (mid-2012) at work. I put Ubuntu 12.04 on it after some efforts. Everything works more or less now, except I get random freezing every now and then. I have to power off the machine to restore it. Wondering if anyone had the similar issue. My setup: MacBook Pro 9,2 (mid 2012) Ubuntu 12.04 (installed using the special image for Macs) No proprietary drivers xmonad on Unity 2D So far the freezes look to be sporadic and spontaneous.

• What can I use to set up a 100% cloud based python IDE + Hosting environment?

  - by PhD

  I'm working a side project and I can't always be on "my" machine to code/deploy the web application. I am aware of various cloud IDEs (e.g., Cloud 9 IDE) and independent Django/Flask etc., hosting services (e.g., Heroku). What is the best way to completely shift my development/deployment environment to the cloud so that I can code/deploy from anywhere? I don't mind using paid services but I'm not sure which cloud IDEs play nice with which hosting services. Has anyone tried this setup before? What has or hasn't worked? I want to minimize the manual intervention in 'connecting the two services' as much as possible. I'm going to be using Django, MySQL and Redis for the web-app
