Anxiety strikes

Sulphur release is getting very near. With all the improvements on F9, somehow, it made me very anxious imagining how RHEL6/CentOS6 would be. With all the improvements Fedora have brought in since Fedora 6, I can only imagine that RHEL6/CentOS6 would be a great distro to recommend for people who don't want to upgrade their distro every half or full year.

With all the device support, the EPEL repository, the giant improvements on yum, PackageKit, FreeIPA, new Xorg, and lots of goodness of a desktop distro, if all these made it into RHEL6/CentOS6, I am nothing but very happy and excited.

RH is abandoning the desktop?. So what?. They let the desktop world move on its own, freely, and Fedora _is_ that desktop. What got in Fedora, got into RHEL too. With CentOS set loose on the internet, high quality Free (both philosophy and price) environment is not that far away from reach. ^-^.

Adding simple popup to Plone frontpage

Here is a little guide for those who want to add a simple popup to the Plone frontpage for some purpose (eg: announcements, advertisements, etc).

Create a basic html file containing the content you want to appear in the popup. Upload it into $PLONE_SITE/portal_skins/custom (as Page Template) and for the sake of this example, name it popup.html

Afterward, create a Javascript file with your Pop-Up loader script. For example , this script:

function popup(mylink, windowname)
if (! window.focus)return true;
var href;
if (typeof(mylink) == 'string')
href=mylink.href;, windowname, 'width=220,height=400,scrollbars=no');
return false;

popup('popup.html', 'My Popup');

Also upload this file into $PLONE_SITE/portal_skins/custom (as Page Template too). For this example, name it as popup.js

Afterward, in $PLONE_SITE/portal_javascripts , add popup.js as a new script into portal_javascripts…

Tee'ing Python subprocess.Popen output

A little hack for python coders out there who wanted to have a functionality similar to the unix's tee command for redirecting output to multiple places.

import sys
from subprocess import Popen,PIPE
p = Popen(['put','command','and','arguments','here'],stdout=PIPE)

while True:
o = p.stdout.readline()
if o == '' and p.poll() != None: break
# the 'o' variable stores a line from the command's stdout
# do anything u wish with the 'o' variable here
# this loop will break once theres a blank output
# from stdout and the subprocess have ended

HOWTO: Mirroring Yum repositories using Yum-Utils

As promised before in one of my previous post, a Howto on how to mirror and manage yum repositories using some of the utilities in yum-utils.

The first step is, well, of course, is to get yum-utils from fedora repository
yum install yum-utils

Reposync is a utility for mirroring and synchronizing local copy of a yum/rpmmetadata repository.

This utility is very useful if you wanted to make a yum repository mirror. Before this, I used "wget -R -np -N" but this method is a little bit tedious and it doesnt work with repos that didn't use directory listing. Plus, it also download together additional site stuff that I don't need/want and it doesn't verify checksum of the downloaded packages.

Mirroring a repo using this utility is easy, just execute this command
reposync -r <repoid> -a <arch> -n
and the repo will be mirrored in a folder with the same name of the repoid in the directory you executed the command. Eg: you executed the command in /mnt/storage/mi…
