Re: [ubuntu-uk] RSI

[Jon Reynolds]

Well thanks for the replies. I think my first action will be a lad under the 
wrist as this seems to make most sense to me. It just feels like I've been 
holding my hand slightly upward over a mouse (sometimes jiggling furiously all 
day) for too long. 

Of course there's always the possibility that it's an unrelated injury but 
that's hard to diagnose. 

Thanks again.

suffered from RSI on and off over the years. My self-prescribed treatments have 
included using differently shaped peripherals in order to give the affected

it's well worth considering professional (or good amateur) massage on the 
affected limbm and even beyond it. While it may feel like the pain is very 
local, in say the wrist, having a thorough massage right up to the shoulder and

shiatsu, try to find the real Japanese thumb-pressure kind, not the trendy 
"holistic" derivatives commonly found on Clapham High Street ;) Of course, any

many of us, I know. Best of luck with the treatment. Roger

Definitely everyone should use a wrist support so your wrist is not
bent backwards when using the mouse.  If you are employed tell your
employer about the problem (if you have not already) and he should
fall over himself to get you all possible aids in order that you will
not sue him.

Re: [ubuntu-uk] RSI

[Andy Braben]

A relative of mine gets RSI pains when using a mouse for just a few minutes.
She just can not use one.

However she gets on very well with a pen and tablet no problem at all, and
using it on Ubuntu right back to 5.10 and onwards and upwards has never been
a problem at all with it.

Regards,
Andy.

There are lots of things you can try: make sure that you're sitting at a
comfortable angle (I had this a while ago because my seat was too low); try
a wrist rest, either as part of a mouse mat or separately; if all else
fails, consider an alternative pointing device like a trackball or even a
graphics pad.

[ubuntu-uk] RSI

[Jon Reynolds]

Hello folks,

Am sure as all of you are computer users, some probably quite prolific 
(as coders etc), that some of you have had experience with RSI.


I have had a bad wrist for a few years now on and off. It always seemed 
to go away but recently (last 4-6months) it seems to be here and not 
going away.


Basically I get a pain in the inside corner of my wrist when it is bent 
back, i.e. in a position to do push ups. I cannot push things (e.g. 
doing push ups) without it hurting and shaking it (shaking inside-out 
socks) hurts too.


I have tried wearing a wrist strap (like a sports one) for the last few 
weeks but it doesn't seem to be making much difference.


I am a CAD user by day, which is very mouse-dependant, but also do an 
amount of typing, but I think the mouse usage is the main culprit as its 
always semi-hovering as I manoeuvre the mouse.


I am wondering if anyone else has had experiences like this and how 
they got rid of it? Maybe those little cushioned mouse mats, where you 
rest your wrist on a small cushion would help.


Thanks,

hi all,

With no testing whatsoever, and only a passing (but google-enhanced)
familiarity with imagemagick, this is how I'd do it in Perl.

Basically, define an array of acceptable colours, then iterate through
the numbers 1 through 111. For each, pick two different colours at
random to use as foreground and background colours and create an icon.

I don't even know if the imagemagick command really does what I want it
to - I got it from [0] - and this could be done in any language, I just
can't remember how to do arrays in bash.


#! /usr/bin/perl

my @colours=("red","green","blue","orange");

for (my $i = 1; $i<= 111; $i++) {

# Pick a random colour for fg and bg out of the array:
my $fgcolour = $colours(int rand($#colours +1));
my $bgcolour = $colours(int rand($#colours +1));

# Check they're not equal
while ($bgcolour == $fgoclour){
$bgcolour = $colours(int rand($#colours +1));
}

# Concoct a command
my $cmd="convert -size 16x16 xc:$colour ";
$cmd .= "-pointsize 8 -fill green ";
$cmd .= "-stroke black ";
$cmd .= " -draw 'text 10,55 \"$i\"' ";
$cmd .= "icon_$i.jpg ";

# Run it
`$cmd`;
}

Avi, many many thanks!

The code above doesn't work straight off, but I've managed to get it 
running (I don't know perl) and now have a working script. Am doing some 
tweaking and will post my version up when that's done.

[ubuntu-uk] Natty bug ....

[Barry Drake]

Hi there   I don't know how to report the following: yesterday's
Natty daily build worked fine, but after installing to a hard drive, the
wired internet connection was not picked up and it seems impossible to
get it connected.  On re-booting into 10.10, the wired connection is no
longer working until I have powered off the computer completely for over
20 seconds.

Plugging a wi-fi dongle in does allow connection, so I guess the
connection manager is not the right place for a bug report.  An thoughts
on how I report this one?

Regards,Barry.

That totally depends on the person and how they learn... for me,
pythonchallenge with hints and a little help from a more experienced
programmer friend really helped me to get familiar with the language.

the Euler Project[0] is also good fun if you have more of a maths
background... and the learning curve is not so steep!

After that, learning to google effectively was very important.

I generate my key as me, my user ID, they are stored in .ssh in my
home directory.

If I want to logon to a remote machine which has a different user ID
then I put my public key in that users folder on the remote machine.
E.g. in /home/support/.ssh/authorized_keys - on the _remote_ machine.

I can then do:-

ssh supp...@remotehost.example.com

or

vncviewer -via supp...@remotehost.example.com localhost

Cheers,
Al.

Re: [ubuntu-uk] Remote support for family & friends

[Byte Soup]

Sorry just repeating my question as it might have got lost in the thread:

It seems if you add a new ssh key into seahorse it always generates a file
called "id_rsa.pub" and "id_rsa", renaming old ones to .1 etc, is that
correct?

When you generate your keys is it always done as the user you are logged in
as? For example my user name on my machine might be "curtis" but I may want
to create a username login on my friends machine as "support" is that
possible and still able to generate a key?

Thanks

Indeed. Seconded. Concur, wholeheartedly.

Just put all the keys in one authorized_keys file and copy that around.

That's not wise. If you put your private key on all your machines you
trust then I only need to break into one of them to gain access to
every machine your public key is on, and you will have to revoke that
one key, meaning you can't ssh to anywhere until you generate new
keys.

More sensible is to generate a separate keypair on each client
machine, and put the public keys on all the necessary targets
machines. That way if I get hold of one of your computers, you only
need to revoke that keypair from all the targets you ssh to, and can
carry on using your other machines' keypairs with no worries.

Hi everybody,

sorry its taken so long to answer, didnt get much computer time yesterday.

I really appreciate the messages. I am going to go in and have a look at 
the ones you mentioned, see how I get on with them.


I did a search for Michael Garrets list, and didnt realise there were so 
many.


Than k you again, that has been really helpful.

Re: [ubuntu-uk] Remote support for family & friends

[Jon Spriggs]

SSH keys are created by producing a pair of cryptographically equivelent
numbers with a size of (usually) 1024 or 2048 bits (I think!) long. When
performing a complex equation, the result of encrypting one with the other
returns the same value. It is not linked to a hardware value.

You can share the same private key around all the machines you own and
trust, and put the public key into ~/.ssh/authorized_keys of the accounts
you are trusted to access. Typically, I create a new account with my
username the same everywhere, but you may want to set it up differently.

Remember, network access (such as port forwarding the VNC port) does not
require you to be in the same account as the user. If you need to act as the
user, you can login with your account and type

sudo su - USERNAME

where username is the person you are supporting. The hyphen in the su
command means "pretend I just logged in as them".

If you are supporting a lot of machines, I'd start looking at creating a
~/.ssh/config file, but from the sounds of things, that's a while off yet!

All the best,

Re: [ubuntu-uk] Programming in Python User Interface

[Scrase, Eddie]

Dive Into Python is available on-line (at diveintopython.org) either to
read or download in PDF format.

Python is indeed a good language to start with, although C++, C#, or
Java are far more widely used in the commercial world.  If you are
serious about using Python, when you feel you have got the hang of the
language you should download the source code for an open source project
that is written in Python to look at real code, modify it, and perhaps
summit changes or bug fixes.

Good luck!

Re: [ubuntu-uk] Remote support for family & friends

I believe ssh keys are generated from hardware I'd's, things like mac address 
etc. 

So I would expect if you created a new users, the old key would still work.

Ive not done much in the way of ssh keys, I looked at the guide on the
Ubuntu wiki here  and it
seems the you always generate a "id_rsa.pub" file, this is the one you put
onto your mums machine and copied it into the ~/.ssh/authorized_keys file?
It seems if you add a new ssh key into seahorse it always generates a file
called "id_rsa.pub" and "id_rsa", renaming old ones to .1 etc, is that
correct?

When you generate your keys is it always done as the user you are logged in
as? For example my user name on my machine might be "curtis" but I may want
to create a username login on my friends machine as "support" is that
possible and still able to generate a key?

2) Enable remote desktop sharing in Ubuntu via the usual GUI options
3) Register a dynamic hostname with dyndns.org
4) Install and configure ddclient to connect and register with
dyndns.org for the chosen hostname

Total time spent: 5 minutes, plus 1 hour mostly drinking tea, chatting
to my mum.

At my house

1) Phone rings!
"Hello Alan, it's Mum, can you help me?"
"Sure, one moment"

2) Open a terminal and type:-

vncviewer -via mums.dynamicdyns.org localhost

*bam* I see her desktop over an encrypted ssh tunnel. No ports exposed
her end other than ssh, and only key-based logon allowed.

Win!

Al.

If you are new to the whole idea of programming, I'd also go and 
download a free ebook called "Snake Wrangling for Kids".


http://www.briggs.net.nz/log/writing/snake-wrangling-for-kids/

As you can probably guess it is aimed at young coders and so starts with 
the real basics, but it is easy to read and, IMHO, a great resource. It 
is for Python.


There are also some cool tools available in Ubuntu that are very helpful 
too:

http://www.ubuntugeek.com/acire-browse-python-code-snippets-quickly-and-easily.html

HTH

And have fun.

DIve is a very good place to start. You might be interested to know that
it's also available online for free so you don't have to wait for it to turn
up ;).

With Ubuntu you have pretty much all you need to start programming in Python
so open up a Text Editor and get started.

[ubuntu-uk] Programming in Python User Interface

[Ubuntu Forum]

Hi

I've been using Ubuntu for around 1 year now

I'm 21 years old

Currently I'm jobless and want to help the Linux community with what I can,
but I don't think I will be 100% of use, due to the fact that if I get a job
I'll find it hard to be available at all times online or for meeting
face-to-face. The other, being that I might get accepted into University but
most likely not because I've failed to get accepted for the third time

I'm trying to learn any Programming language. I heard Python is good for
beginners and that's where I want to start

Will be getting this book from Waterstones soon - I've ordered it:* *Dive
Into Python (Mark Pilgrim)

I'm having difficulties and need just a little bit of assistance in how to
start with the basics then I think I will become a lot better since I have
great appreciation and curiosity for technical things

So I'll be very grateful if that support is provided
