Underclocking at home

How slow can you go?

Go into your bios and find out!

I find an older dual core system can be slowed down to ~1.2 GHz, and still play YouTube and MythTV full screen quite well.

An older system, so not HD.

Cool!, My system does not overheat any more ;)

sageMath Myth(TV) plot

here's a sagemath plot of disk usage from my MythTV:



generated to find out the show taking up the most space...

here's a bare sql query to show in text

select title, 
   sum(filesize) 
 from mythconverg.recorded

   order by sum(filesize) desc ;

---

and my actual sage script:

import sys

##did not install MySQLdb into sage, only default location, so had to add
sys.path.append('/usr/lib/python2.7/site-packages/')

import MySQLdb 

print "MythTV File sizes"

import _mysql
db=_mysql.connect(host="localhost",user="myuser",passwd="mypassword",
                 db="mythconverg")

db.query(""" select  @rn:=@rn+1 rn, sum(filesize)/1024/1024 from (select @rn:=0)r, mythconverg.recorded  group by title order by sum(filesize) desc""")

r=db.store_result()
scatter_plot(r.fetch_row(0))
