Color and Other Calibration on PC Monitor

I am currently using this monitor :

Current Settings (under white tube-light from top) :

Brightness : 25/100
Contrast : 25/100
Color : Standard (6500K)

Aim : To study the effect of Color Temp on eyes

Ref : Google :  color setting in monitor 5000K to 9300K

Conclusion :

Setting the temperature too low will cause your monitor to work harder to achieve adequate brightness and may result in banding or other artifacts. Setting the temperature too high though will cause increased eye strain since the average indoor lighting from incandescent bulbs is down around 3400K. As a compromise, something in the middle tends to work best for most users.
Then there is the question of what effect this has on attempts to get your monitor to match your prints. Most of us don’t have the luxury of controlling the color temperature of the light under which our work gets displayed, but the choice of lighting will have an impact on what it looks like. White paper will take on a warm or cool cast depending on the light source, and an image printed on it will too. If you are printing images to be hung under controlled lighting conditions, you can achieve the best match by setting your monitor to the same color temperature as the light source in the display area. If the light in your house is a mix of natural window light and artificial, you are again forced to compromise. If you sell your work, you are at the mercy of a light source you will likely never even see with your own eyes. Thankfully, everything else around your hung print will be under the same lighting and without any absolute frame of reference, the eye easily adapts, minimizing the problem to all but the most discerning viewer.

Chrome Version’s and Flags’ effect on Memory Consumption

Well, the aim here is to see if there is any consequence of Chrome Version and Chrome Flags on the memory that chrome consumes

Test : 5 Tabs open and 5 extensions are enabled

Contender 1 : Dartium 28

Consumes almost 800 MB memory

Contender 2 : Chrome 26

Consumes almost 600 MB memory

So, Yes there was some affect due to the version

Next : Flags

Nope, the chrome flags (i hae most of the experiments enabled) had no observable affect on the memory.

Lessons in Managing my Windows Machine in Office


This is an on going lesson in effeciency and management, though i must say that my machine is now  much better organized now than it was 6 months back…

Here are some tips :

1. Create shortcuts for everything. …. XP doesn’t provide many options, but the simplest thing is to create Ss for every damn thing.

Eg : Folders, RDP links, Bookmarks (I use Google Bookmark)..

2. Use Outlook and communicator extensively. I am not that good with Names, so i use contects section of O to create categories of Projects, Teams etc and put people in there….

Xobini is a good add on for outlook analytics
Create rules in outlook

2 things i kearnt the hard way in outlook rules are :

Make sure u arrange the Rules in order of Priority (of application) and 2, in every rule check the Box which says :  After applying this rule, stop processing other rules.

Another settting that i found very helful for mail management is : File-> Options – > Mail Options   -> When replying to a message, keep the response in the same folder


I was conscious of my typing speed when i first joined MS and wanted to be a touch typist in a day …I hence practised for 4-5 hours for few days and got nowhere… i used to panic in hurry and hence screw up the words….infact i am doing that right now…the only thing that i have done in the past year is to continue touch typing but while looking at the keyboard and not the monitor..and voila… now finally i’m seeing the fruits after an year and can type without looking…..mostly

3 .Make others admin on your machine so that even if ur access goes they can make u admin again…or if u can’t login, they can login to ur machine and access the data.

4.  Create Mail Templates so as to not have to write the same things again and again.

5. Create shared folders and create one which has full access to everyone so that anyone can put stuff in it

6. Keep your dextop and inbox blank…arrange everything in folders and tags….

7. the second time u use anything, create a shortcut for it…and …the second time u DO anything, FIND a shortcut for it

8. IN Outlook create tasks out of mails with reminders so as to not forget anything ever…

9. Note down imp stuff that others tell you, as there can be nothing worst that asking them to repeat the same thing later….

Access Device Camera using Sencha Touch

1 .

    source: ‘camera’,
    destination: ‘file’,

    success: function(url) {
        //show the newly captured image in a full screen Ext.Img component:
        Ext.create(‘Ext.Img’, {
            src: url,
            fullscreen: true


success: function(image) {
quality: 75,
width: 200,
height: 200,
destination: ‘data’

3. <input type=”file” id=”take-picture” accept=”image/*”> :


1. Use the HTML 5 API for accessing camera. : Adv. Then we can provide a web interface of the app too… and also single code
2. Use the Native OS API to access the camera using phonegap…DisAdv : will have to write seperate code for seperate OSs.

In option 1 , i checked that we can’t use WEBRTC ( as its not implemented in Chrome or Firefox or Safari.It works only on Chrome Dextop for now.
