A decent way to read articles online

Do you browse a lot, reading articles or diverse fields, and move from one website to another.

Then you must have come across websites, which are pretty badly designed as far as the readability is concerned.

I come across tens of such sites everyday, which have a black background, a grey text color, and some really cool article , worth a try.

So, here is a workaround,

Create a new bookmark, on your bookmark tab, and Give it any name, you feel like, Eg. Readbility.

Then, in the URL box,  paste the following code

javascript:(function(){readStyle='style-newspaper';readSize='size-large';readMargin='margin-narrow';_readability_script=document.createElement('SCRIPT');_readability_script.type='text/javascript';_readability_script.src='http://lab.arc90.com/experiments/readability/js/readability.js?x='+(Math.random());document.getElementsByTagName('head')[0].appendChild(_readability_script);_readability_css=document.createElement('LINK');_readability_css.rel='stylesheet';_readability_css.href='http://lab.arc90.com/experiments/readability/css/readability.css';_readability_css.type='text/css';_readability_css.media='screen';document.getElementsByTagName('head')[0].appendChild(_readability_css);_readability_print_css=document.createElement('LINK');_readability_print_css.rel='stylesheet';_readability_print_css.href='http://lab.arc90.com/experiments/readability/css/readability-print.css';_readability_print_css.media='print';_readability_print_css.type='text/css';document.getElementsByTagName('head')[0].appendChild(_readability_print_css);})();

That’s It !!! Whenever, you need to read a page, which is not readable, due to its design, colors, fonts and sizes, just click on this bookmark.

Checking out Cheat Engine 5.6

I laid my hands today on Cheat Engine 5.6, and once again jumped into the world of de-compilers and Hex.

Readers should try it for once, to get a feel of the subject. I tried the manual, which has a nice tutorial to cheat Windows Pinball.

Its fairly simple, and easy to learn.

Bought a new Laptop

Bought a new Laptop, HP Pavilion dv4 2123TX  :)

Pretty excited about it, and to add to the excitement, this one comes from hard earned cash !

The machine is performing pretty well, but I miss a backlit keyboard.

So, now I too belong to the elite brigade of people with more than a couple of devices ! Cheers !!!

Issues with Floating Point Calculations in MySql

Regular comparisons over floating point numbers have some serious issues. The documentation states that DECIMAL type should be used for such comparisons, since they are stored as strings.

Floating point numbers are saved in a platform dependant format, and a simple value 9.78 , might not pass the test someVariable=9.78

The work around for such a problem is to use Round(someVariable,9.78)=9.78 ,for your code to work in the desired manner.

Archiving your Favourite Mails in Gmail

*Update* : This 5 year post could not keep up with the latest version of firefox and gmail. Continue reading further without any hope of making it work. 

Lately, I had the need to get a few of my chats for archiving offline, but not to my surprize, I found that GMail does not offer any such service, where I could get my data in XML/JSON or a compatible format.

So, I decided to start-off a small venture, to get this thing working.

After a small amount of reverse engineering, I figured that, every chat has a unique msgID, which can be used to get a neat and clean HTML formatted; printer-ready format. But for this to work, needed to fetch all the msgID.

The Trick

• Every Email is saved as a conversation, each conversation has a msgID and subsequent threadIDs
  
• When printing a mail, by its ThreadID, all the threads in the mail are concatenated as neat and clean HTML page
  
• Once, one reaches this Printer-Friendly page, it can be saved in plain HTML format
  
• Then, using MS Word, one can concatenate such files together, and in the end generate a nice index of emails.
  

 
The Prick

I Assume, you have already setup the required Label. If not, please get a hands-on on a tutorial to Gmail Labels, and once you master the art, come back to this page.

The following steps have been tested on Firefox 3.5.5.

STEP 1

Download and Install iMacros for your version of Firefox. The best way to do that is to Google for it !

Once you install iMacros, you will have a folder named iMacros inside your My Documents folder. Go inside that folder and the inside Macros.

STEP 2

Create the following files there ( with the attached content )

SaveMails.iim

VERSION BUILD=3700331

TAB T=1

TAB CLOSEALLOTHERS

CMDLINE !DATASOURCE mails.csv

SET !DATASOURCE_COLUMNS 1

'SET !LOOP 2

SET !DATASOURCE_LINE {{!LOOP}}

SET !EXTRACT ""

URL GOTO={{!COL1}}

SEARCH SOURCE=REGEXP:"((Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)[\s][0-9]{1,2},[\s][0-9]{1,4}[\s]at[\s][\d]{0,2}:[\d]{0,2}[\s](AM|PM))" EXTRACT=$1

SAVEAS TYPE=HTM FOLDER=* FILE={{!EXTRACT}}


 
Links.iim

VERSION BUILD=6650406

TAB T=1

URL GOTO=javascript:javascript%3Am%3Dprompt(%22How%20many%20mails%20are%20their%20in%20this%20label%3F%22)%3Bu%3Dwindow.location.href%2Cs%3D%22%22%3Bl%3Du.substring(u.lastIndexOf(%22%3D%22)%2B1)%3Bu%3Du.substring(0%2Cu.lastIndexOf(%22%3F%22))%3Bfor(i%3D0%3Bi%3Cm%3Bi%2B%3D50)s%2B%3D(u%2B%22%3Fs%3Dl%26l%3D%22%2Bl%2B%22%26st%3D%22%2Bi%2B%22%3Cbr%3E%22)%3Bdocument.getElementsByName(%22q%22)%5B0%5D.value%3Ds%3B


 
ShowMessageIDs.iim

VERSION BUILD=3700331

CMDLINE !DATASOURCE links.csv

SET !DATASOURCE_COLUMNS 1

'SET !LOOP 2

SET !VAR1 {{!LOOP}}

ADD !VAR1

TAB OPEN

TAB T= {{!VAR1}}

SET !DATASOURCE_LINE {{!LOOP}}

URL GOTO={{!COL1}}

URL GOTO=javascript:s%3D%22%22%2Cu%3Dwindow.location.href%2Cs%3D%22%22%3Bl%3Du.substring(u.lastIndexOf(%22%3D%22)%2B1)%3Bu%3Du.substring(0%2Cu.lastIndexOf(%22%3F%22))%3Bt%3Ddocument.getElementsByName(%22t%22)%3Bfor(i%3D0%3Bi%3Ct.length%3Bi%2B%2B)s%2B%3D(u%2B%22%3Fv%3Dpt%26s%3Dl%26l%3D%22%2Bl%2B%22%26th%3D%22)%2B(t%5Bi%5D.value)%2B%22%3Cbr%3E%22%3Bdocument.getElementsByName(%22q%22)%5B0%5D%3D(s)%3B

STEP 3

Switch your Inbox to Basic HTML View ( The Link is at the bottom of the Page )

 

STEP 4

Make sure you are viewing the right label, i.e the one for which you want the mails to be archived.

STEP 5

In iMacros, locate the Links.iim file and play it. Enter the approximate number of email that this label has

 

Thereafter you will see a list of links on the page, select the whole text, and create a new file in "My Documents\iMacros\DataSources" named links.csv. Use NOTEPAD to do this, and not Microsoft Excel. Paste the text there and save.


 

 
STEP 6

Back to Firefox! Locate the Macro named show showMessageIDs.iim. Play (Loop) this Macro, and change the default value "3" to the approximate number of links you saved in STEP 5 (eg. 10, An approximate and large value would suffice.) .This will open a few tabs in your browser depending upon the number of mails you will be archiving.

STEP 7

Create a new File named mails.csv inside "My Documents\iMacros\DataSources" . Open this file in notepad, and then copy the contents of each TAB that opened from the previous step, into this file. Finally save this file.

STEP 8
Disable Javascript by unchecking Tools-->Options-->Content-->Enable Javascript in Firefox.
Now locate the Macro SaveMails.iim, and Play (Loop) this macro, to the number of Mails you wish to archive. An approximate and large value would suffice.

STEP 9

Once STEP 8 completes, ( which will take some time), you will have each of your mails in the folder "My Documents\iMacros\Downloads" . Now comes the more interesting part, Open Microsoft Office ( The code has been tested on Office 2007 ). Go to VIEW-->MACRO-->VIEW-->MACROS-->CREATE MACROS . Provide any arbitrary name, it doesn't matter !

A new Window will open

 
Select all the text and Delete it. Then paste the following Code

ISSUES
The following issues remain unresolved

• The MS WORD Macros become very slow for more than 100 mails
• Need to save the mail files into groups,month wise
• The Regular Expression matching is extremely slow

 

 

Executing lengthy processes at Server –Side

There are situations when certain tasks require the server to take time in responding, not because of the size of data, but because preparing that data takes time.
Under these circumstances, one could use a AJAX based approach to notify the user of the progress, and auto-load it, once the data is ready.
The following steps need to be performed

1. Make an asynchronous call to the server with the required parameters
2. The server will respond back with a notification, and a couple of call-back functions, which holds a URL to check the progress of this particular task.
1. CheckProgress()
2. GetData()
3. Wrap the CheckProgress() call-back function is a time-interval loop, and make further asynchronous requests to check the progress.
3. The Server will respond with the percentage of work complete.
4. Once the Server says, it’s complete, i.e. 100% completion, clear the time-interval loop.
5. Make another call to the server, using the GetData() call-back function.
6. This method will return the data, augmented with a function, which holds the controls to load this data at client-side.

Workaround for Joomla 1.5 and Mootools 1.2 Integration

Hi folks, I was stuck for some while to make my joomla installation work as required since the backend was still using mootools 1.11 while I was using mootools 1.2 .
This is how I solved it.
Edit the file behavior.php which is located in /libraries/joomla/html/html  ( your path may be different.. search for the file in that case )

Move to line 53

and add the following code in the else block

$a = $_SERVER['PHP_SELF'];

       

        if(strstr($a,'administrator'))       

            JHTML::script('mootools.js', 'media/system/js/', false);

            else JHTML::script('new.mootools.js', 'media/system/js/', false);

What this code is supposed to do is, check the current URL, and if it contains the word administrator, the old version of mootools is loaded,
else the newer version of mootools is loaded.

Management Funde

Lately I have observed a Tiny Fact about task distribution and quality of output from your peers. It turns out, that 90% people are good for everything ( provided the job does not require extensive domain expertise). It is also visible that for generic tasks its better to go for in-experienced professionals than the professional ones, since they are a little arrogant due to their experience. On the other hand, the in-experienced ones are cautious of the fact that they have to perform and thus display a better show.
Secondly, throughput decreases with increased experience and success.
I'd like to emphasize that this observation is only useful for common tasks of management and not those involving a level of technical/non-technical detail of the job.

Sergey Brin's resume before he co-founded Google contains some interesting bits, including two comments hidden in the HTML (this looks authentic, but if you know more please comment). The first one reads:

<!--<H4>Objective:</H4>
A large office, good pay, and very little work.
Frequent expense-account trips to exotic lands would be a plus.-->

The second one:

Google Reader Tracking Changes of Any Web Page

Google Reader Tracking Changes of Any Web Page

via Google Blogoscoped by Philipp Lenssen on 1/25/10

Google Reader can now act as a general web page change alert system, Google announced. This means you can now try to subscribe to updates for a particular page even if that page does not have an RSS feed. As before, submitting a URL into the "Add a subscription" box should be enough, Google says. [Thanks Abhisshek and Niranjan!]
