Python needs to be embraced for it's capacity to gel with android so well and make things easier with simple and fun scripts.

After installing G+ android app, /me was curious about instant upload of images that the app provides, so decided to make a simple script to emulate the same, but as imgur is one my favs, used the same.

Instant upload images to imgur is a simple script that does :

Figlr is a simple fun tool to generate FIGlet text. Those are normally used to make ASCII art banners.

It makes use of Figlet-JS which is a JavaScript implementation of a FIGdriver and is also available as a Node module and a jQuery plugin.

The code :
The code is a simple javascript trick, to listen on the paste and keyup events from a text area and populate a pre tag with the FIGlet text.

Deleting SMS text has been on of issues with default SMS clients of Andriod OS. Issue 5669 talks a lot about it.

The most common alternative is to use different SMS clients, that allows bulk delete.

But using some simple python script, deleting SMS from inbox is just a click away, provided one has SL4A installed on the device.

Simple python script to delete SMS from inbox in Android devices :

This is more a tribute to Master Yoda rather than coding!

The idea was to use a simple python script to update my gmail, tiwtter and identi.ca with a random saying from Master YODA from Star Wars!

Yoda for me is not a mere character for a movie, but he is a philosopher, motivator and indeed the renowned Jedi master.

Python modules needed :

• XMPP
• tweepy

Some extra steps for twitter
For oauth all one needs to do is create an twitter APP with Access level to be read and write in our case.

After creating note down the : consumer_key, consumer_secret, access_token_key, access_token_secret.

All is well now, GET SOURCE modify the creds and enjoy!

Yes the yoda_says list can read read from a file, better read randomly with linecache, but just wanted to have a single file for the easy of it.

You feel there are more quotes to added? Suggest them! ^_^

After Random images from wikipedia I made another simple API to get the summary for a search term using PHP.

It's a JSONP API that queries the DNS of wikipedia to fetch the TXT records, which also includes a short URL to the complete corresponding Wikipedia entry. As cross-domain requests are possible with this API, one can easily integrate it to search boxes or widgets.

Monkey code :

After Random images from xkcd as wallpaper it was time for some more fun, this time did a simple script to get Random images from

Getting client IP address is one common thing most of the web developers do, but getting the same with JavaScript is not possible as there is no notion of hosts or ip-addresses in the standard library.

True, there are many such services that provide IP in JSON format, but is it not better to trust yourself ;) ?

Just for the fun of it, made a simple service using PHP that would return the clients IP address in JSON and the same can be used in a client side scripting language like Jquery.

The php code :

Compressing files

is one of the most common tasks any programmer would have done. The below is a simple comparison of compression paradigms of selected programming languages i have really liked!

This post is much influenced by :

• comparative study
• Methods to post to a form

Sending an SMS programmatically using python in an android easier than any other programming language

All one needs to have is Scripting layer installed in the mobile device.
Use the QR code below to get the apk and install the required and then install the python interpreter.

It all started couple of months back, on a fine sunny morning i read a mail with a subject Career Opportunities @ Google at first thought it was a spam mail, but then to my astonishment and delightment it wasn’t... then the mail read :

Hi Hemanth,

I'm writing to introduce myself and inquire about your interest in confidentially exploring opportunities with Google. Please let me know if you have a few minutes to discuss.

I support a team called the Google.com/Site Reliability Engineering and we are currently looking for different types of engineers to help support some of the current and upcoming exciting projects.
Ideally we are seeking technical generalists with fluency in coding/scripting, fundamental knowledge in systems administration, network administration and strong analytical and troubleshooting skills.

This team is hiring in San Francisco, Santa Monica, Pittsburgh, Kirkland, Seattle, Lenoir NC, Las Vegas, New York as well as Dublin, London, Zurich, Munich, Sydney. If this does not sound like the best fit for you, there are several other teams hiring as well.

In the event that you're happily employed, but know of any engineers of your quality who may be on the market, please don't hesitate to pass along my contact information.

Thank you in advance for your consideration! I look forward to your reply.

I could not believe my eyes! That i had received a mail from GOOGLE! To be frank, I had not applied to Google in any of their portals and was extremely excited and replied to the mail saying,I was interested and had attached my resume with the mail (Not that Google wanted my resume, as they would know be better than me ;) )

I got a quick response for my mail saying :

Hi Hemanth,

Thank you for your interest in Google! I support a team called the Google.com/Site Reliability Engineering and we are currently looking for different types of engineer to help support some of the current and upcoming exciting projects.

What I have in mind for you is a unique hybrid position. As a Google.com engineer, you wear many different hats and and are expected to be a jack-of-all-trades. It calls for solid knowledge in Unix/Linux Systems, Scripting/Coding and Networking and/or Databases. We put the best and brightest on this mission-critical team to solve large scale, highly complex problems related to Google's customer-facing sites and internal services.

I'd love to have a brief conversation to gauge your interest and tell you more about the team. If you could provide me with a few time slots that would work for your schedule over the next few business days, I will confirm one with you.

So all excited Hemanth, gave few time slots and dates where he would be free and would be easy to talk. ( Talking to one about yourself is the toughest thing to do! NO?).

CALL 0
So the clock ticked 22:45 hrs i was about to sleep, but wanted to surf some reddit, my cell rung time was exactly 23:00hrs! As soon as i noticed it was an international call ( Call was from California ) plugged in my head phone and said hello, I heard a charming voice a lady from the Google recruitment team,
she got to know more about me and explained me about how working at Google would be and what they are expecting from a candidate.

CALL 1
This was about what i had learnt so far and what would be covered in the up coming interviews. Was requested to prepare on basic of whatever i had studied in my bachelors as a computer science grad.

CALL 2
Around 23:15hrs about a week after CALL 1, This call had question that would gauge me and suggest me the right stream in Google that would suite my true nature. Call was all about the basic of Computer programming, Networking, GNU/Linux and indeed algorithms.
Sorry can't disclose the questions, after this round I got a mail saying that i had cleared this round and need to get ready for other rounds.

CALL 3
Before the CALL 3 really happened, I had to give list of time slots with in a given range, that was like 23:30 to 04:00 hrs [IST] yes time seemed bit odd, but that is how they like it and more over the Engineer who was supposed to talk my interview was in US, so had no other options. It's hard to focus at odd hours especially when you had a long day at work, but that is not the whole point, if there is real love in technology time must not matter!

This call was very interesting, it also included Computer programming, Networking, GNU/Linux and a shared Google document where i had to code on a given problem [ Can't share more details here too! ]

Call ended with me saying, "I could not be at my best, really don't know why! May the odd time or over excitement", other end the Google engineer said, i can understand no issue, if any more questions please contact the recruitment team.

So Call 3 was it i knew i had screwed up, could have done much better! After few more days got a mail that my resume will be in there repo if there are more jobs that are apt for me they will get back.

Even though i knew the answers to all of them, was not able to delivery it in the right manner and with the same level of confidence, which i would have done with any other company!

RETROSPECTION

I'm must say that disappointment is indeed echoing in me, but must be happy as Google Getting 1300 Resumes A Day chose me, from one of the open source sites where i had done my contributions! Indeed has boosted my confidence!

Lesson Learnt

<

ul>

With this i thank Google for giving me such a great opportunity! No matter what reasons i may list now, the past is past and lost is lost.

In life, we need to face failures to realize the taste of success…they are like injections; they pain but it's a good pain!! So if it does not end well, then there is more to come!

Apache Module mod_dir provides "trailing slash" redirects and serving directory index files. "The DirectoryIndex directive sets the list of resources to look for, when the client requests an index of the directory by specifying a / at the end of the directory name. Local-url is the (%-encoded) URL of a document on the server relative to the requested directory; it is usually the name of a file in the directory. Several URLs may be given, in which case the server will return the first one that it finds. If none of the resources exist and the Indexes option is set, the server will generate its own listing of the directory."

How to have different index to sever from the same directory?

The idea :

A simple case study of downloading files in perl, ruby, python and php.

The algorithm :

Assumption : The input for these scripts are obtained from a simple cgi form.

• 0. Hit an URL which in turn responds with a list of URLs ( Like RealMedia Metafiles )
• 1. Download the contents of each URL that the is returned from the master.
• 2. Zip all the downloaded files and exit.

Downloading files in perl :

What is GNU MediaGoblin?
Initially, a place to store all your photos and artwork, more better than (Flickr, DeviantArt, SmugMug, Picasa, etc). Later, a place for all sorts of media, such as video, music, etc hosting.

P.S: This will mostly be usable system by September 2011.

Many love browsing through Google Logos, so do some of my friends, was planning to make a simple page with infinite scroll with all the Google Doodles so far.

The idea
To programmatically fetch all Google logos so far and display it with infinite scroll, also to keep the page in sync with Google logo list.

The plan
Using Yahoo! YQL to select the required section from the Google logo page and display the images suitably. As YQL also returns a JSON, displaying the required images was not a big issue.

The key ingredients : Yahoo! YQL + Jquery

I came across the thecolourclock wanted to check out the source sadly it was build in flash
so tired to make one with some HTML and JS. Check out thecolorclock. [See time in colors :)] The idea is to represent time as a hexadecimal color value.

Multi lingual translate bot code in ruby after the xmpp ruby chat-bot this bot is coding in ruby with the help of to_lang ruby gem.

Demo of the bot :

Will be adding more flags for the easy of use soon!

How the bot works?
It makes use of Google translate API the response that will be returned by the server will be a JSON

Python provides a easy way to handle JSON, by importing the**  json  **module, one can easily encode a list of dicts or a dict of dicts so on, but there is a easy trick to generate a JSON or even a nested JSON string from an object of a class.

`json.dumps(obj[, skipkeys[, ensure_ascii[, check_circular[, allow_nan[, cls[, indent[, separators[, encoding[, default[, **kw]]]]]]]]]])`=> Serialize obj to a JSON formatted str

Many time one needs to get the redirected URL, the reasons might be many but the logic remains the same. HTTP request response is what it's all about, say if an URL has a redirection, one can find the redirected URL in the RAW headers of the response, the location would be the HTTP/1.1 307 Temporary Redirected URL.

With the xmpp and irc bots : l33ty.l33t and l33ty so far i'm having fun coding them, of all the methods in them i liked the goog method, which returns the first URI from the list of URI's returned from the Google web search API, that is the linear implementation of IMFL search.

First up is python:

After Python-IRC-bot my interest was in making a gmail bot, that lead me to make a simple bot very much like the previous irc bot, its called rgbot.

To add the bot to your contact : add l33ty.l33t[at]gmail[dot]com

About rgbot
XMPP Gmail Bot in rb ; rb+gmail+bot => rgbot. rgbot is an XMPP bot build with ruby, that runs on gmail and can do things like :

* l33t translation

It started with the intention of making a simple IRC l33t translate bot after the l33t translation API.

l33ty is an IRC bot build with python with the help of twisted modules and uses "Reactor pattern". l33ty can do few many things like :

* l33t translation
* Google I'm feeling lucky search
* Karma system
* XCKD random images
* Flipping a coin, throwing the dice

Preparing your system

Here I introduce a dynamic 733+ translator an on the fly translator similar to Google translate.

Where i can see the translator in action?
You can here in the demo page [[ not much of an eyecandy ]]

What is l33t?
"Leet, also known as eleet or leetspeak, is an alternative alphabet for the English language that is used primarily on the Internet. It uses various combinations of ASCII characters to replace Latinate letters. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t." [[ wikipedia ]]

Dot rc files are not supported by all the shell, but on those which it's supported we often edit ~/."$SHELL"rc files and source them or exec the shell. I made a small python app using which one can select the login shell from the list of shells installed in the current system.

I call it cpld a simple utility for copying shared library dependencies to a given folder

"Time is constant, we come and go", but the beauty of earth is so, that time varies with space.

I made a simple BASH script to convert between different time zones, as i badly needed one such app, that would give me time in my terminal.

We have all combined a pdfs in the past, and it all seems easy until you come across a situation like this!

Limpid is a simple gtk application coded in python, as there was a requirement for the course named Scripting-101 which i'm mentoring on Mozilla P2PU. The app has a window with a split screen, where in the first part of the split is a simple webbased IRC and the other part is a virtual GNU/Linux terminal.

It all start with a simple idea, i got of embedding a vt in a terminal, later on it turned out to be a stand alone all, with a browser and a terminal in it! Absoluteness of pygtk, even the same can be achinved with QT4, there are few many massive apps, out there, but this one is a minimal app to meet the requirements.

Diaspora => The privacy aware, personally controlled, do-it-all, open source social network.

Was seeing lot of people facing issues to in set up, including me at the beginning, so i thought to make a setup script for ubuntu os,which can be cloned from my repo [[ Mentioned below ]].

I have tested it to the max i could, still it might not be fool proof, do try and let me know if you find any bugs.
