Setting autocomplete to work in Windows gedit

Filed Under: GEdit, Plugins, Python, Windows

autocomplete-plugin-running-in-windows

Today a friend told me that my gedit autocomplete plugin wasn't working under his Windows box. So I decided to check why and learned a lot of things. Basically the plugin doesn't work because the binary version made for windows brings a custom python.dll which doesn't come with the python json library. So, in order to make it work, you need a working version of the json package and copy it to the place where gedit python.dll is expecting it to be and change the places of some files XD

Discovering the network online computers

Filed Under: Ubuntu

A while ago I faced a situation where I had to discover the online computers in our network and I ended coding the following small shell script which basically try to detect them by ping:

#!/bin/bash

if [ "$#" != "3" ]; then
    echo "Invalid script call. Use './map-network.sh <base> <a> <b>' (eg 192.168.0. 100 199)"
else
    base=$1
    a=$2
    b=$3
   
    echo "Mapping network from $base$a to $base$b"
   
    for i in `seq $a $b`;
    do
        ret=`ping -c 1 -W 1 $base$i`
        proc=`echo $ret | awk '{split($13,a,"="); print a[1]}'`
       
        if [ "$proc" = "ttl" ]; then
            echo "$base$i is active"
        fi
    done
fi
 

But today I realized my naivety and learned that nmap is a faster and better tool for the job! The exactly same result is achieved by executing the following code in the terminal:

$ nmap -sP 192.168.0.*

There is also a more interesting variations which, given a range, looks for the current open ports in each computer:

$ nmap -sP 192.168.0.*$ sudo nmap -sS -p 1-1024 192.168.0.*

That's it... I hope this article helps someone else other than myself in the future :D

Lack of updates apologize

Filed Under: ASP, Miscellaneous, VBScript

I've received emails asking me about the rest of my ASP articles and the only thing I can say for now is: "They will arrive...". Sorry I couldn't put a deadline for them 'cause while I know exactly what I want to write, it costs me a lot of time to search for the references I want to cite and currently time is not an available asset. I'm working hard on some Collective Intelligence based algorithms and documents and I must finish it until 2010.02.12, so the blog updates will be minimal. But don't worry, the articles are in the 2010 TODO queue for sure XD

gEdit AutoComplete 0.10.0

Filed Under: ASP, GEdit, Plugins, Ubuntu

I'm very glad to announce today that I'm releasing gEdit AutoComplete plugin version 0.10.0. Now the plugin has features that I was really missing and it just cost me a little of time between Xmas and new year, so it's my first gift for the programmers in 2010. HAPPY NEW YEAR!

Important Notes

This is probably my last iteration of the gEdit AutoComplete plugin using the current architecture, 'cause the gEdit core team (pbor, jessevdk, nacho and others) are working on a native GTKSourceCompletion engine that should be the basis for the next version of this or the gEdit official one. Meanwhile, I'm inviting anyone interested to make additional language libraries to make the plugin better while the stable official version isn't available.
