Simple script to get the exchange rate.

Some time ago I made a small script to find out the exchange rate.
I have not used it much and today I came across it.
Who needs something, here's how it looks:

from xml.dom import minidom as dom
import urllib
def fetchPage(url):
a = urllib.urlopen(url)
return ''.join(a.readlines())

def extract(page):
a = dom.parseString(page)
item2 = a.getElementsByTagName('SendingDate')[0].firstChild.wholeText
print "DATA ",item2
item = a.getElementsByTagName('Cube')
for i in item:
if i.hasChildNodes() == True:
e = i.getElementsByTagName('Rate')[10].firstChild.wholeText
d = i.getElementsByTagName('Rate')[26].firstChild.wholeText
print "EURO  ",e
print "DOLAR ",d

if __name__=='__main__':
page = fetchPage("http://www.bnro.ro/nbrfxrates.xml")
extract(page)

That's all.

Parsing files and rename ...

Sometimes you have to rename files.
This can be tiring when we do it manually.
Command "sed" may be helpful in this case.
I'll take a simple example. I will create a working directory called "work."
We have to create files with the command:

for (( i=1; i<10; i++ )); do echo data$i > data[$i]x[$i].txt;done

The result should be :

$ ls
data[1]x[1].txt  data[3]x[3].txt  data[5]x[5].txt  data[7]x[7].txt  data[9]x[9].txt
data[2]x[2].txt  data[4]x[4].txt  data[6]x[6].txt  data[8]x[8].txt

Try these commands to parse and rename files:

$ for i in  *[]x[]*; do mv -v "$i" "$(echo $i | sed 's/[]x[]//')"; done
`data[1]x[1].txt' -> `data1]x[1].txt'
`data[2]x[2].txt' -> `data2]x[2].txt'
`data[3]x[3].txt' -> `data3]x[3].txt'
`data[4]x[4].txt' -> `data4]x[4].txt'
`data[5]x[5].txt' -> `data5]x[5].txt'
`data[6]x[6].txt' -> `data6]x[6].txt'
`data[7]x[7].txt' -> `data7]x[7].txt'
`data[8]x[8].txt' -> `data8]x[8].txt'
`data[9]x[9].txt' -> `data9]x[9].txt'
[work@test work]$ for i in  *[]x[]*; do mv -v "$i" "$(echo $i | sed 's/[]x[]//')"; done
`data1]x[1].txt' -> `data1x[1].txt'
`data2]x[2].txt' -> `data2x[2].txt'
`data3]x[3].txt' -> `data3x[3].txt'
`data4]x[4].txt' -> `data4x[4].txt'
`data5]x[5].txt' -> `data5x[5].txt'
`data6]x[6].txt' -> `data6x[6].txt'
`data7]x[7].txt' -> `data7x[7].txt'
`data8]x[8].txt' -> `data8x[8].txt'
`data9]x[9].txt' -> `data9x[9].txt'
[work@test work]$ for i in  *[]x[]*; do mv -v "$i" "$(echo $i | sed 's/[]x[]//')"; done
`data1x[1].txt' -> `data1[1].txt'
`data2x[2].txt' -> `data2[2].txt'
`data3x[3].txt' -> `data3[3].txt'
`data4x[4].txt' -> `data4[4].txt'
`data5x[5].txt' -> `data5[5].txt'
`data6x[6].txt' -> `data6[6].txt'
`data7x[7].txt' -> `data7[7].txt'
`data8x[8].txt' -> `data8[8].txt'
`data9x[9].txt' -> `data9[9].txt'
[work@test work]$ for i in  *[]x[]*; do mv -v "$i" "$(echo $i | sed 's/[]x[]//')"; done
`data1[1].txt' -> `data11].txt'
`data2[2].txt' -> `data22].txt'
`data3[3].txt' -> `data33].txt'
`data4[4].txt' -> `data44].txt'
`data5[5].txt' -> `data55].txt'
`data6[6].txt' -> `data66].txt'
`data7[7].txt' -> `data77].txt'
`data8[8].txt' -> `data88].txt'
`data9[9].txt' -> `data99].txt'
[work@test work]$ for i in  *[]x[]*; do mv -v "$i" "$(echo $i | sed 's/[]x[]//')"; done
`data11].txt' -> `data11.txt'
`data22].txt' -> `data22.txt'
`data33].txt' -> `data33.txt'
`data44].txt' -> `data44.txt'
`data55].txt' -> `data55.txt'
`data66].txt' -> `data66.txt'
`data77].txt' -> `data77.txt'
`data88].txt' -> `data88.txt'
`data99].txt' -> `data99.txt'

This is just a simple example ...

OpenGL and Python - Motion blur

What is glAccum? The OpenGL function - glAccum operate on the accumulation buffer.
This function provides support for many special effects.
Today I simulated the effect of motion blur with this function.
See the picture below:

OpenGL and Python - Fog

Today I spent my time with something new - the OpenGL fog effect.
I made one simple fog effect using the last code source.
The result is this image:

"Santa Claus" on Google Map

I wrote on my blog python-catalin.blogspot.com about Google Map and Santa Claus:

I wrote a python module. I called it "geo" because it is a geographic module.
The funny stuff is when i use it with "Santa Claus".

>>> import geo 
>>> geo.adress("Santa Claus")
{'status': '200', 'latitude': '32.1715776', 'longitude': '-82.3315138', 'accuracy': '4'}

So where is Santa Claus ?!
Google Maps API should be prepared to respond.
Tomorrow a child will know how to use the Python language.
Who knows ...

Christmas is coming.

I love Christmas. I like going shopping. I love snow.
Two days ago, inspired by this holiday I started to create an application.
Here's what came out.


As you can see is not wallpaper, is just a python script.

News: Go - a systems programming language

Do you hear about "Go"?
This is the logo :

...and this is the code:

package main
import "fmt"
func main() {
fmt.Printf("Hello, 世界\n")
}

One of the text comments I found is:
" this combines the style of Python, the syntax of vBasic, and the speed of C?"
For me is like "perl".

First post on planet.fedorapeople.org

I tried to connect to planet.fedorapeople.org.
I asked several people but it's Monday and world works.
After several unsuccessful attempts and internet search, I started the setup.
Some of SELinux settings and this is the result.
However, some settings ssh should be underlined.
I mean ssh_config configuration file and some security settings.
It seems that I succeeded.
