Re: [ubuntu-uk] Building Ubuntu for the Raspberry Pi, on the Raspberry Pi
I use python on the pi all the time, it works just fine for me, but I don't do much time critical stuff. Printing to the console is a bit slowish, but I do plenty of stuff responding to USB events and flashing LEDs attached to the GPIO and stuff like that. Mostly not desktop applications, just scripts that control things, log data to databases, that kind of stuff. I have also installed OpenERP on the Pi, that is a biggish python based server application. It wasn't quick, but neither was it slow enough that I didn't manage to install it, (including postGRES) and set up a company in it over the course of an evening. Alan. On 07/11/13 16:19, Tyler J.

Same here with ls and cd in front:
$ awk '{print $1}' ~/.bash_history | sort | uniq -c | sort -rn | head
407 ls
283 cd
217 git
171 vi
114 make
53 dot
52 sudo
47 rm
44 erl
41 grep
The only reason why python is not up there is because I tend to do chmod +x
on my python scripts. I also had a dot and Erlang frenzy recently (not
together though).
What is also interesting is how it changes when you include the first
parameter. The positions of "git status" and simple "ls" showing that I
regularly need reminding what the hell I've just modified and what was in
there in the first place:
$ awk '{print $1 " " $2}' ~/.bash_history | sort | uniq -c | sort -rn | head
242 ls
72 git status
53 make
53 dot -Tsvg
50 vi Makefile
43 git add
41 vi test.sh
41 bash test.sh
39 git commit
33 cd ..

Hi Alan, Please add "make Python not suck on Raspberry Pi" to your list of requests. Execution time for python is so bad I had to rewrite a number of my tools as shell scripts.

The ranger CLI file manager is awesome too if your familiar with vi/vim. I use it a lot for getting to where I need to be.

[ubuntu-uk] Python / django dev for REST API prototype
Hi all, This is slightly off-topic but I thought people on this list would be the right audience. My company, EnergyDeck [1], just got granted an "innovation voucher" from the TSB [2] which means I have a small budget to do something "innovative" under the following conditions: - I need to do this through a UK based SME with whom we've never worked before, - Said SME needs to produce a short (1 page) report at the end of it. What I need doing is a prototype for a REST API that would sit on top of our platform, written using python + django + a REST API django plugin. The scope of the prototype is flexible but needs at the very least to do this: - Include basic support for developer API keys that we would issue, - Authentication via OAuth, - Performance testing for some of the queries that may return a large amount of data. The deadline is flexible but I would like to at least start this side of Christmas. If you are interested in doing this for us, please contact me off list and we can discuss the details. Cheers, Bruno [1] http://www.energydeck.com/ [2] https://www.innovateuk.org/ -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

The script is 40 lines of code and produces print ready output. The benefit of the script route is that you can customise the source and content so for example, you can make the script pick up all the photos that are within a date range and automatically generate your photo album based on that which means you could do a "my year in pictures" album every Christmas. Or you can generate album and labels using the same source of data by just using a different template. Of course, if it's for a one-off, Scribus is the right tool for this. On the other had, why spend 5 minutes doing something when you can spend 5 hours automating it? ;-) Cheers, Bruno -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

[ubuntu-uk] Presence on Google Plus
Hello all, It was suggested on IRC that we (the loco) might want to have a presence on G+. This seemed like a good idea given we have quite a good presence of Ubuntu in general on G+ (120K people in the Ubuntu community). So I created https://plus.google.com/communities/108756253446581210513 which is a Google+ "Community" for the Ubuntu UK loco team. It could grow, or it could whither and die, that's up to us really :) No obligation to join of course, just another place where people can discuss / promote Ubuntu UK :) Happy happy, Cheers, Al. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
