Well I have been fidling a lot with openid and valkertown’s services and now most of them are openid enabled as consumers.
Here’s the list:
- Blog comments are now openid enabled
- Finisht my fork of finisht I have added my fork, #hashtags support and openid consumer support
- Gclap, Gclap is my attempt to start a GLUG here in Colombia that is not student oriented and most industry oriented, yet I have to find time to push/promote it.
I have to see if I can setup valkertown’s xmpp server as an openid consumer so using speeqe rooms will become even easier
Well, please give them a try and if you’re in Colombia and like my idea of the GLUG drop me a word.

Today around 6:00 AM GMT-5 my grandmother Ana Celia Vega passed away while sleeping. Incredibly while I didn’t meet with her a lot I remember that we were being quite attached to her and having a lot of fun while visiting her house.
Well this post is just to test the laconica tools plugin for wordpress. This message should end up on my identi.ca feed announcing a new post made.
Well, after having spent all my time with GNU/Linux using my favorite distro, which is almost 8 years, I finally moved away from Slackware. Not that I have any problem with it, it’s just I found a distro that I like even more.
My new distro of choice is now Archlinux, which happens to be a quite updated distribution contrary to slackware, I have yet to see the stability and all that, but after a week of using it I have found I can spend less time fiddling with source installs and still don’t being bothered by excesive system automation. As far as binary builds Arch respects the source and will not alter the stuff that’s installed also I have seen very few patches applied to the source.
My favorite part of Archlinux are the PKGBUILDS which are smart enough to create packages from source code coming from git/svn/mercurial/darcs/etc… checkouts and handle the packaging and still gives me full control of the build process and patching. This is pretty important for me since I happen to run most of my day to day software from version control checkouts with custom patches and compilation and this is the first non-slackware distro that I can do that without fighting at all with the distribution.
While installing Archlinux I found that my old lvm schema that used root as vg and one lv was a big mistake since it interfered with kinit,udev and some scripts during the boot process. On slackware I didn’t had any trouble since I had modified my boot to handle that, yet on arch kinit simply will not work if that schema persisted, so I had to change my vg and lv names (not a big deal but I wasted so much time figuring out)
So far being very happy with it, no more compiling a lot of packages I didn’t like and can keep kernel compilations to the minimum since Archlinux software list is really up to date. This really helps when you use new software or happend to be dealing with really recent hardware.
Finally I really doubt I ditch Slackware at all, since I have a load of projects that still runs over the slackware platform and ideas but with time I will update them all to arch, including my microwulf cluster that I have on the CIF’s basement.

Well since I barely use my jaiku account, even when it has xmpp support. Probably is that I’m not really interested on the conversations there and no one uses jaiku channels. It would be a lot better if it used something like “track” the one you find in identispy for identi.ca, twitterspy for twitter and Jance for Pownce.
Anyway I decided that I wouldn’t bother setting yet another account on some random service to update identi.ca,twitter and jaiku at the same time so I decided to write something myself.
After very little effort I came out with this, it’s pretty basic and with ZERO error checking but it does what I want.
I used feedparser and simplejson python modules.
-
#!/usr/bin/env python
-
-
import simplejson
-
import urllib
-
import feedparser
-
import time
-
import re
-
-
identica_rss="http://identi.ca/IDENTICA_USER/rss"
-
user = ‘JAIKU_USER’
-
api_key =‘JAIKU_KEY’
-
-
class JaikuInterface:
-
method = ‘POST’
-
api_url = ‘http://api.jaiku.com/json’
-
def __init__(self,user,key):
-
self.user=user
-
self.api_key=key
-
def post(self,message):
-
body_dict = (
-
(‘user’,self.user),
-
(‘personal_key’,self.api_key),
-
(‘method’,‘presence.send’),
-
(‘message’,message)
-
)
-
body = urllib.urlencode(body_dict)
-
try:
-
f=urllib.urlopen(self.api_url,body)
-
ret = simplejson.loads(f.read())
-
f.close()
-
if ret[’status’]==u‘ok’:
-
return True
-
else:
-
return False
-
except:
-
return False
-
-
-
-
jaiku = JaikuInterface(user,key)
-
last_date = time.mktime(time.gmtime())
-
oldest = last_date
-
time_fmt= "%Y-%m-%dT%H:%M:%S+00:00"
-
striper = re.compile("^deepspawn: ")
-
stripuser = lambda(x): striper.sub("",x)
-
while True:
-
try:
-
identifeed=feedparser.parse(identica_rss)
-
for entry in identifeed.entries:
-
entry_date = time.strptime(entry.updated,time_fmt)
-
entry_date = time.mktime(entry_date)
-
if entry_date > last_date:
-
oldest = max(entry_date,oldest)
-
post = stripuser(entry.title)
-
jaiku.post(post)
-
last_date=oldest
-
except:
-
pass
-
time.sleep(5*60)
-
Well just replace IDENTICA_USER, JAIKU_USER and JAIKU_KEY with your values and that’s all.
It will poll every 5 minutes the rss and update jaiku with the new dents.
Well that’s all, it’s a small hack I hope someone find this interesting.

Hoy mi compañero Diego recibio este divertido correo desde la Dirección Nacional de Programas de Pregrado
Diego: Cuando la Universidad Nacional decidio abrir el abanico de modalidades para el Trabajo de Grado y quitar las menciones de Meritoria y laureada, no penso en lo que se venia luego: como incentivar y premiar a todas las variaciones de Trabajo de Grado. Como no es lo mismo hacer una pasantia y presentar un reporte a estar todo el semestre frente a un microscopio observando algo superespecial para el desarrollo de la humanidad, pues no se esta actuando con equidad pues el reporte de la pasantia no encaja en el formalismo del concurso mejores trabajos de Grado, asi le hayan puesto de nota 5 y haya tenido un desempeño sobresaliente… La UN debe pensar como premia a los excelentes en cada modalidad pero aun no lo ha hecho. El concurso premio hasta los trabajos de 2007. Falta 2008 pero ahora el enfasis esta en la reforma academica para implementar el acuerdo 033 en el primer semestre de 2009. Asi que solo hasta el 2009 se pensara en como hacer la seleccion y en ese tiempo se premiarian 2008 y 2009 y se haria difusion a lo que se concrete. Por ahora no. Feliz tarde,
Yo empezaré la discución sobre este tema, pero mi opinión personal extendida la dejo como un comentario.

Speeqe is a tremendous idea to bring multi user chat(MUC) into the simplest possible web service you can think, if you want to invite your friends they all just have to follow an url you send and start chatting, things can be more complicated but it’s not required to start participating. Well now I have installed speeqe on my own server quite successfully, it wasn’t an easy task, yet it wasn’t that difficult.
If you want to try it check it here: Valkertown’s rooms you will need a Valkertown’s jabber account to test it, but I will solve this problem asap.
Here’s a list of some of the stuff I had to work around:
- There’s still a lot of hardcoded strings in the js,css,templates with the speeqe url
- The templates, js,css doesn’t prepend the djangos settings for MEDIA_ROOT, I wish I solved this nicely but all I did is set them
manually.
- Everything on my test server is server using an https connection that includes the http-bind. I figured how to solve this and it was not a big deal.
- I had to do some minor modifications to the django/python client so it connects using https and to the ejabberd’s bosh module.
Here’s some of the stuff I disabled.
- The demo stuff
- The register stuff(I simply didn’t understand it) I tought it created a new xmpp account but it looks like it doesn’t, just an speeqe account, correct me if I’m wrong.
- Virtual host, I’m not planning to do subdomain rooms.
- Message search, I don’t like much this feature, I would like more a room search.
- The static urls serve in the urls, I would activate it using some kind of flag, it’s just not good to see it there, I think it may lead to problems.
Here’s some of the stuff I modified:
- I replaced virtual host to normal chat rooms urls, I would like and plan to setup shorter urls for local rooms without using dns
- Templates to match my own domain where it made sense.
At last:
- I’m missing the autologin feature, I’m guessing on how to deal with this but I want to keep the modifications I do to the code at a minimum.

Well, today in the afternoon I was given a task, make the
Usb Instruments DS1M12 usb osciloscope in linux, it was quite a surprise
to find out it had some kind of support for Linux and I started my work with their sources.
I found it requires two downloads one from USB Instruments itself and another from a thirdparty driver
Well, those two comes with some .so files you need to link your programs so you need to make sure
they have proper names like libDS1M12.so, libftd2xx.so and they can be found in the LD_LIBRARY_PATH or something like that, this is important.
After you get this solved it’s pretty straightforward with the USB Instruments package comes a good example you can use to understand their library, this took a bit of time since we(called some one to help me pinpoint some problems) could get it working and seeing the data flow quite fast, yet, it took us some time to discover that the sample code enabled the testmode and instead of real sampling, after that we could see the two channels sampling also the signal generator send out the example signals.
After this we agreed that it would be good to have a python interface to this osciloscope and I started working with swig to generare a proper wrapper around the USB Instruments library, around an hour ago I finished what we could call the first release of the interface and I’m being able to plot some data using matlplot lib. It took me a bit to figure how to manage to wrap some of the functions yet in the end swig and numpy solved all my issues.
I’m not really sure If I can release everything at the moment, I think I’ll have to ask USB Instruments since I use one of their headers to build the swig wrapper and it requires some minor modifications to make it work nicely so I would have to publish the modified header. If i get permission or any idea how I should publish the repository, it will be here at valkertown Mercurial Repositories
For now you have to beleive me that now the use of this osciloscope it’s reduced to something like this

Well, here is it, I will keep an eye on it before I add it some where in the page, anyway I’m far more
active on identi.ca than on pownce or jaiku, also I support more the ideas that identi.ca represents.
Also I changed the badges at the right of the blog for some flash based ones, one for Pownce
one for Jaiku, they good look good.
We’ll see with time how it evolves.

I have just fell in love with this image I found at ImgFave, which is a laconi.ca based place. Check Identi.ca to see the original place.
From the signature it looks it was written the year I was born, it just make me feel more in love with the message.
Feel free to copy and share it with everyone you know since this is the way it was passed to me and after a quick google it looks like it’s the overall intention of this message.
Enjoy! Seriously !
