SSH and Strawberry Perl

Strawberry Perl doesn't come with SSH modules pre-installed.

Here is how to insall

C:\>perl -MCPAN -e shell

cpan shell -- CPAN exploration and modules installation (v1.9304)
ReadLine support enabled

cpan> install Net::SSH
Fetching with LWP:
http://cpan.strawberryperl.com/authors/01mailrc.txt.gz
LWP failed with code[500] message[Can't connect to cpan.strawberryperl.com:80 (connect: timeout)]

As a last ressort we now switch to the external ftp command 'C:\WINDOWS\system32\ftp.EXE'
to get 'C:\strawberry\cpan\sources\authors\01mailrc.txt.gz.tmp3104'.

Doing so often leads to problems that are hard to diagnose.

If you're victim of such problems, please consider unsetting the ftp
config variable with

o conf ftp ""
o conf commit

I would like to connect to one of the following sites to get 'authors/01mailrc.txt.gz':

http://www.perl.org/CPAN/
ftp://ftp.perl.org/pub/CPAN/

Is it OK to try to connect to the Internet? [yes] yes

ADSL on Ubuntu 9.10 (Karmic Koala)

Working with ADSL modems on Ubuntu 9.10:

Configure: pppoeconf

sudo pppoeconf

Check: rohit@lenovo:/etc/network$ more interfaces auto lo iface lo inet loopback iface dsl-provider inet ppp pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf provider dsl-provider auto eth0 iface eth0 inet manual
Start: pon
rohit@lenovo:/etc/network$ sudo pon dsl-provider Plugin rp-pppoe.so loaded. RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5
Stop:poff
sudo poff
Log:plog
rohit@lenovo:/etc/network$ plog Dec 8 16:37:45 lenovo pppd[11102]: Plugin rp-pppoe.so loaded. Dec 8 16:37:45 lenovo pppd[11102]: RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5

This method works well for BSNL's ADSL lines in Kolkata.

Download HD Trailers from Apple Trailers

Apple movies now 'stream' mov files, they cannot be saved (like they us. for example, if you view the HD movie trailer for the movie "GOOD" - the URL on the page leads to this stream:
http://movies.apple.com/movies/ifc_films/good/good_1080p.mov
Saving link creates a mov file of 75k - not the movie.

In order to download, add the letter 'h' (Hidden) to the movie file name:

wget http://movies.apple.com/movies/ifc_films/good/good_h1080p.mov

HD-Trailers.net has an article on this and a tip for Yahoo HD Movie Trailers - which I've never used...

The Green Way to Fax (paper-less)

If you are like me and work with PDFs a lot, often times you get PDFs that you may need to PRINT and sign, then fax - because they can't accept e-mails etc.

PRINTing and Faxing wastes Paper on both sides. 

There are many FOSS tools in Linux that allow you to edit PDFs, insert Text and images.

1. Use PDF Editor to open a PDF document, and open it for editing 
2. You can insert text and/or images (like a scanned ink signature)
3. Once done, simply save it as a PDF, or JPG image.
4. Now you have an electronic document filled out and 'physically signed' to be faxed away

PDF Editor provides a very good interface to open a PDF and edit it in multiple ways, repackage and save it as a PDF.

Go to Ubuntu Software Center and search for 'PDFEditor'

Initialize Interpid Ibex

Well well - I decided to remove Vista from the Vostro, downgraded to XP and dual-booted with Ubuntu 8.10

Installation was smooth as ever and grub worked perfectly. Dell ships with these broadcom network adapters that need b43 drivers - thankfully these are provided with the new dist.

There is a bunch of software that I typically need/want/desire - here are the steps to get it

I don't mind free closed-source software, so edit /etc/apt/sources.list & enable what's disabled.

Enable medibuntu:

sudo wget http://www.medibuntu.org/sources.list.d/intrepid.list -O /etc/apt/sources.list.d/medibuntu.list

sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

Now go for the mass install - remember Google & Sun want you to agree with their license terms - so keep an eye out for those when the time comes tab to Ok and hit enter.

Note: When you run Google Earth ensure that you have not Desktop Effects enabled.

This should provide nearly all the functionality that's needed for a baseline O/S installation.

Recover Dual Boot XP, Ubuntu 8.04 (Hardy Heron)

Issue: I needed to reinstall Windows XP on a dual-boot machine. No new partitions were needed, there were 2 O/S partitions - one with XP and the other with Ubuntu. After reinstalling Windows - the machine would simply boot into Windows XP (no dual-boot menu)

Solution: Boot from Ubuntu LiveCD - choose to demo. Then open terminal.

iTunes Audio only Podcast & Video only Podcast SmartList

(I) Unplayed Audio Podcast smartlist that plays 100 audio unheard unskipped podcasts starting from the earliest added.

Podcast is true
Play Count is 0
Skip Count is 0
Kind does not contain MPEG-4

Limit to 100 items selected by least recently added

To create a Video podcast just change the Kind parameter on the smartlist to "contains"

You can sort the list so it will play by artist, album (most Podcasts have album names consistent), genre etc

Setting Video Kind to Movie admits most video podcasts however others get filtered out - so avoid this parameter.

Mule ESB Distribution

So I started playing with Mule starting Feb 2007. Mule is an integration platform that allows for pluggable connectors to other types of systems. There are so many descriptions of ESBs and architecture styles, and almost everyone claims to be an expert in the space.
IMO Mule is basically a container-type framework that rests on various open source products...
if you go to the 1.4.1 distribution's opt folder the listing is as such:

Writing a web-service is as simple as creating a POJO & modifying the configuration file with the right parameters.

Dump Google Sync for FoxMarks

Just when I thought I would have to write a bookmark sync tool for my machines, I stumbled upon Foxmarks. It was like someone read my mind of the design I had thought and just coded it. Brilliant, thanks Foxmarks you have saved me weeks of coding & deployment! I am a happy user of it, it sync my bookmarks across machines effortlessly.

Recommendation: Dump google synch, del.icio.us, tag for Foxmarks. http://www.foxmarks.com/
