Ubuntu :: Optimal OS For Netbook Python Robot?
Jun 8, 2010
defer to your expertise in determining the best Linux OS and desktop environment. I have a some (ok, a lot) of control code written in python for a mobile robot. The robot is for my graduate research project, and until now I have been running the code on my system76 laptop or my netbook (running Ubuntu Remix 9.04). However, we just purchased a project netbook (Samsung, Atom N450 processor) and I would like to install the lightest weight OS possible to reserve as much processing power as I can for the code. A no frills, barebones linux version that can run python.

I have installed CentOS 5.5 and Skype (static version)
And for some unknown reason, my voice through mic sounds like a robot.
I have tried to use my mic with Skype on my Windows XP machine, it works fine. Hence, it is not my mic issue.

Player-Stage uses .cc files. I know how to compile them. But how do I actually execute my code? There is an output file generated. There is nothing in the .cfg file or in the .world file that specifies what program to use to run the robot. Or is it not specified in the world or cfg files?
Then how to make the robot obey my compiled .cc file? If this question is silly or if I am asking stupid questions

I am trying to create a RS232 C program that executes a series of commands down the line to a robot. Everything seems to work fine, except any sequential write to the serial port. At first I thought it was the UART's buffer being filled too fast, but even with a 50 uS delay it still throws the error.
Here is my code:
Code:
#include <termios.h>
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/signal.h>
#include <sys/types.h>
[Code]...

I've got the latest version of Flash installed,and it works most of the time,t occasionally a video or game will stop working and the area it was in will just turn into a grey box. Usually it only does this if I leave the page the video's on, but it keeps doing it when I'm playing Robot Unicorn Attack on Adult Swim's site, too

I'm thinking about installing Arch soon, but I was wondering what the optimal partition setup would be. Bhalash on #ubuntu recomended:
boot as sda1
swap as sda2
personal data (not config) as sda3 **
the extended partition as sda4 which would include
-Ubuntu
-Arch
This would not be a home folder, it would just be for person files like pictures or music. The OS's would have their own /home which would contain symlinks to this partition. Does anyone see anything wrong with this setup or have a better idea?
Currently on my setup:
sda1 is a broken ubuntu 10.10
sda2 is extended
sda5 is swap for broken install
sda6 is my working install
sda7 is swap for working install
So keep in mind how easy it would be to move the partitions around in your response. I haven't found a way to move something out of extended without frying the data.

I've been tinkering with both recently to see what can suit my needs as a simple raid1 mirrored backup server. I used FreeNAS for all but minutes before I had a raid1 array running and shares set up through CIFS. Using Ubuntu on my laptop I was able to see them as well. I had some more figuring out to do, as I wanted each share to be blocked off from the other. aka - I didn't want "fred" to be able to access "bob's" share. So then I move on to Openfiler to check it out. I hear it's simpler. It's web interface, while no doubt much slower than FreeNAS, was easy to mingle around. At first glance, I thought I'd like it more.
I began to set up my raid1 array. After realizing the final release I was dealing with had a bug, I found some commands to run in a root shell to fix. Okay, so now we're moving along... raid1 array created. Then I had to create a volume group. Then a volume. Then shares. And I still don't have it running over cifs. I'm curious if FreeNAS by nature is truly simpler to set up raid array's with, or if maybe I'm just totally misunderstanding Openfiler and that be the reason why I'm thinking this.

Desired features:
1. Does not support DRM.
2. As lossless as possible.
3. Plays on Android devices including Xoom and Nexus One.
4. Supported by most major players.
5. If the best format is a bit lossy, then it has to be something I can get from most media stores.

I installed this package (Squeeze) and the man page for laptop-mode.conf is rather overwhelming in the amount of information it provides, as is the .conf itself; does anyone know if simply installing laptop-mode-tools has an effect on power consumption? In other words, does the default .config save power? Or do I have to alter the .config? If so what would an optimal .config for an EEE PC look like?

I'm wondering if there is anything I can do to get the best speeds possible. I pay for 16mb/s connection (with charter) and I was getting about 4mb/s. After upgrading firmware, and changing some encryption settings on my router, that went up to about 6mb/s. It's improvement, and I'm happy with that, but I'm looking for that 10 more mb/s
So, is there anything in Ubuntu to tweak to optimize connection speeds? Also, if it affects anything, I'm using a linksys WRT320N router. I was going to use the 5.0ghz band, but my wireless adapter is an 802.11gb, so I'm stuck with 2.4.

I have a fresh install of debian on an older laptop. The screen resolution is 800 x 600, but I want it to be 1024 x768. I know this screen can handle this resolution because I've used it before. I tampered with xorg.conf according to this link, viewtopic.php?t=26577, but to no avail. Here is my xorg.conf
Section "InputDevice"
Identifier"Generic Keyboard"
Driver"kbd"
Option"XkbRules""xorg"
Option"XkbModel""pc104"
Option"XkbLayout""us"

When I take photos at some work outings, I set up my camera to take large pictures (jpeg + raw) just in case someone really likes a photo and wants to print it (well, it hasn't happened yet, but you never know). I then have to resize the photos to email them (I photo takes over 5MB). What would be most optimal settings to resize them for emailing? I used to just decrease the resolution:
mogrify -resize 25% *.jpeg
This, however, doesn't change the compression and possibly any other settings that I'm not aware of.

I've already used line split stuff to transform my data into something like this in a text file:

['3', '1', '3', '-1.5768747']
['4', '1', '3', '-26.4772491']

I would like to discuss setting up a mail server and its implications and alternatives. First, let us see if I have understood this correctly: A mail server consists of many different components. First, a server to listen to any mail inbound for a specific domain (say postfix), and then a POP3/IMAP server (say dovecot). Then, I should somehow configure the rules by which all mail is forwarded to their respective owners. This should be fairly simple by using debians package managers and dselect or whatever program it is that sets up right packages by use cases at the install.
But now lets assume a more complicated environment, where there are multiple users with different domains and needs. First, we need to send mail to ourselves from webapps for instance for backup purposes. So let's say we have a domain called domain.com setup, and we want to send mail to backup@domain.com. Unfortunately, some configuration issue makes the application get confused, because it is trying to send mail to itself, but doesn't quite understand what it should do. How can this problem can be solved?
Second, how could I configure different domains with different rules. For instance, if I want one domain to have a catch-all account, where random email sent to erroneous accounts is captured? Or if I want to create accounts which are not based on actual Debian accounts, but instead just random usernames (say, danny@domain.com, mike@domain.com, support@domain.com etc.)?
Finally, which are the best web-guis for doing such configuration? What if the customer wants to himself add accounts? I cannot require him to edit text files - especially if he can thus break the whole configuration for other customers as well.. postfix-admin is one, but it is quite crude-looking. Is there something which integrates both postfix, apache and dovecot configuration? How about Webmin?

I just got a new SSD, and I'm looking for advice on how best to incorporate it into my existing LVM setup. I have the following logical volumes (mounted at the obvious places):
[Code]...
I've got 108.26g in the physical volumes associated with the new SSD. I'm going to use pvmove to migrate some of these LVs to the SSD. The question is, which LVs to move?
The machine in question is basically a home workstation. I do some light development (source code lives in home), run some very low-load server processes (apache, etc.), and do a bit of image and video editing from time to time. I run Gentoo on x86 if that makes a difference.

I have disabled root login in my remote shell and I have a pretty strong password. I am not happy though. I want to increase security. I've been thinking about installing some basic tripwire rig, like say, send myself an email every time I (or anyone) log in. My questions:
- What kind of data would be useful to be sent in that email? Anything else besides "user so-and-so logged in at {date and time}"?
- How would I achieve that? Is it enough to include it in .tcshrc (because my shell is tcsh)? Should I add it to other shells as well (.bashrc, .csh etc.) even though nobody uses the other shells? Is it better placed in some other file, like .login? What is the optimal place?
- Would that be enough? Can I make that whole idea more secure in any way?

in ubuntu 10.10, I have installed python 2.7. I would like to use apt-get to install packages to this version of python but I haven't been able to figure out howThings I have tried without success:changing the symlink at /usr/bin/python to point to /usr/bin/python2.7 - even after doing this apt-get still installs stuff to python2.6.Set up python2.7 as the primary alternative using update-alternatives - doesn't work

This is a fresh install of stable Debian: root@ngaio:/home/murray# uname -a Linux ngaio 2.6.32-5-amd64 #1 SMP Wed May 18 23:13:22 UTC 2011 x86_64 GNU/Linux The monitor is an AOC F19s - fairly standard 19" widescreen LCD. The graphics is running off the mother board: Intel Graphics Media Accelerator X4500 (supposedly this supports up to 2048x1536)
Gnome has three basic resolutions available, the best is 1024x768 but it still makes my pictures look fat. The optimal resolution for my monitor is 1366x768 (ie widescreen). I have hunted through lots of posts and tried creating an xorg.conf file and specifying this mode, however when I did that the Xserver simply didn't start. I then tried a few different combinations, however I was pretty much swatting mozzies with the lights off. I deleted my xorg.conf attempt and it's back to 1024x768 and I'm stumped.
[Code]...
I know these resolutions are painful to work out, so if you don't have much time perhaps you could point me at a website or document that explains how to configure xorg.conf correctly?

I am installing a custom 8.04 live disk (basically, a mirror of my whole system with user data intact, sans all non-OS files) from a USB key with remastersys for the .iso creation, and UNetbootin for the bootable USB on a brand new 120GB PATA WD HDD. Both do nicely so far, so I have a working livedisk to use until I need to install Ubuntu to the drive.
I had a pure linux box, but I need to add XP with dual booting now- I have to use Autodesk Inventor 2010 software for my college class on my laptop, so I don't drive 30 miles to use the 1 computer lab equipped with that software. I'm not new to Linux, but I am new to more in-depth partitioning. I've taken the lead and looked into things- read this good guide, among others:
HTML Code:
http://www.psychocats.net/ubuntu/partitioning and noticed that there is a way to more deftly use partitions so that personal files can be shared access and write between Windows and Linux partitions- with this:
HTML Code:
http://www.fs-driver.org/ Ubuntu is still my main OS, but being able to access all my media/data files between the 2 systems would be nice. Problem is, until now, I've put everything on a single partition because I didn't know better. Now I do, but am a bit confused with all the guides as to what's most efficient, especially in my case where full RAM speed is crucial to running a single program.
Here's what I know I need to do: 1. The Windows XP install I know needs from 20-30GB for Inventor 2010 LT to work well. I don't need anything else in XP spacewise- it's just being added for Inventor. 2. I'd like to create a separate /home partition for Ubuntu this time to save my user data, making future upgrades much more painless (I will be getting Lucid soon). How that works when upgrading, though, I don't know yet..
3. I'd like both OSes to share all my personal files (docs, pics, music, Inventor design files) if it is an efficient choice that works without problems.
4. Finally, because 2GB is minimum for Inventor to run decently, I need to maximize the speed of my RAM for it- from my reading, these so-called "swap" partitions can somehow be added for buffering this- people seem to sugguest the swap be half the size of the RAM for fastest speed, and some say add separate /usr or other partitions. I'm not clear on what would be most efficient for me.
I have limited HDD space- because of my laptop's BIOS, this single 120GB drive is the biggest I can get on my laptop, so efficient partitioning would make a huge difference for me. Before this, a 60GB HDD was in this. I'd like to see some added space for my data storage, but still keep things as fast as possible for Inventor when I use it, and Ubuntu.

I am having trouble installing Ubuntu 10.10 netbook remix edition onto a Acer Aspire one netbook. I am attempting to install the OS from a 16GB PNY usb drive w/ the usb-universal installer and ubuntu 10.10 netbook remix .ISO
The reoccurring problem that I am encountering is that when I boot from the USB-drive and begin to install everything seems to be working, and then it is stuck at the menu where it asks who are you?; and of course i have filled in everything asked and at the bottom where you can look at what its doing in the terminal/detail section all it says is ready when you are, and the forward tap is unselectable.

Why i cant change from 800x480 to 1024x600, that this model of EEE pc doesnt support anything higher than 800x480 at the 10:1 ratio...
Firstly my question is, is it ACTUALLY possible to 'overclock' this type of netbook to run a higher res?
Im running ubtuntu netbook remix 10.04 and am new to linux (again, so sorry) so be nice, and ive tried getting my head around this 'sudo' stuff, and the xorg.conf file (which is nowhere to be found) and ive even tried a program calld astray but im pretty sure ive exhausted my patience as trying to self-teach . . .
And ive also tried to much around with xrandr or whatever that command was.. but i cant really get my head around it, and it kept telling me the resolution didnt exist ect...

For the past 2hrs I have been struggling to make KDE launch plasma-dekstop instead of plasma-netbook, but all in vain.I removed, then purged plasma-netbook and plasma-netbook-default-settings packages but after logging out and re-logging in the Netbook UI was back! After restarting the system now I can't even seem to get the KDM. I am greeted with a black screen.--- I restarted the system again and the nasty little bugger is back again! This is so frustrating. How do I get plasma-desktop to load instead?---- Great now I can see that plasma-desktop and plasma-netbook both are running simultaneously! netbook on top of desktop. So my final Q is how do I stop plasma-netbook from loading?

I installed Ubuntu Netbook 10.04 and immediately noticed the keyboard of my eeepc 1000HE was abnormally warm. Since I dual boot XP I booted to XP and found the fan running faster to compensate for the previous heat. This did not happen on Ubuntu-the fan just was barely running. I had to place the side of the netbook in order to feel the fan running. I issued "sensors" in terminal and it showed 67 degrees C for the cpu temp. Is the latest Ubuntu such a resource hug that it heats up the CPU?
