Simple rss to email service for your feeds on Linux with your/ISP server.

2010-01-01 2 min read Fedora Linux

I like couple of blogs and feeds but the problem is that I keep forgetting to run the rss reader and would rather like to have the rss article’s emailed to me at regular intervals so that I can read them when I want to without having to make sure that I am at my desktop at home computer or remembering to start the rss client. That sounds simple and do-able so lets try to do that.

query and downgrade selected packages based on version or repository

2009-12-24 1 min read Fedora Linux

If you have worked on rpm based distro then you know how difficult it is to downgrade packages. And unluckily I upgraded some packages to fc12 and was still on FC11. Completely my mistake while doing some R&D. Anyway to downgrade I had to device some mechanism and here it is:

rpm -qa –qf ”%-30{NAME}%-20{RELEASE}\n” |grep fc12 |awk '{print $1}’|tr ’\n’ ’ ’ >downgrade

yum downgrade `cat downgrade`

Finding all numbers that are bigger than 1 in vim

2009-12-24 1 min read Fedora Linux Vim Tips

/^([2-9]d*|1d+)
If we have a csv like structure

The trick here is simple, lets look at the regex from the begining:

^ – start from the begining
() – start and end of block
[] – digits within this. So we are looking from 2 to 9 to exclude the numbers begining with 1
d – search for digits

– search for one or more
| – or operation
1 – search for numbers begining with 1

– containing atleast one occurence or more.<h6 class="zemanta-related-title">Related articles by Zemanta <ul class="zemanta-article-ul"> <li class="zemanta-article-ul-li"><a href="http://sparksspace.blogspot.com/2009/10/adding-leading-zeros-in-excel.html">Adding Leading Zeros in Excel (sparksspace.blogspot.com)

and add the following lines

baseurl=http://spot.fedorapeople.org/chromium/F$releasever/
enabled=1
gpgcheck=0

Once this is done, you can install the browser with yum as follows:

sudo yum install chromium
