Poor Shock Absorbers : How to take on Speed Brakers

I have been riding a gear-less scooter for couple of years.
These are the most selling vehicles now a days, as they are easy to handle in city traffic and gives storage space as well as comfortable driving.

As these scooters are mostly made for the city and short rides, they usually do not have very good suspension for rough roads (like our bikes have). And when I bought one I really found it's tough to hit any Speed Breaker. 
But with time, understanding my vehicle, some research and experimenting I could find some right techniques.

So a simple technique to ride/drive when you run oven a speed breaker is "Always try to touch the breaker when you are on throttle/accelerator and not on brakes".

Sounds confusing :), here goes how.

When you use breaks you front shock absorbers will get compressed, and that condition is not good to hit speed breaker as they will not have more suspension left to face shock.
So when you see a speed breaker, try to slow down your vehicle a little before it, not just when you touch it.
Now as you have already slowed down before the breaker, we go for important part.
Just before touching the breaker, means when you are few inches or a feet to the breaker, accelerate your vehicle a little. Amount of acceleration totally depends on your vehicle but
it should be just a push, do not get in speed again.
This small push (acceleration) makes the front shock absorbers to come up to full height again. And so they are ready to take on the shock. And you will cross the breaker more smoothly then ever.

This appears difficult; but when you practice this technique, it will be your habit like other rules of driving. And once you are good in it, it will not only make your drive smooth, but you will even be able to go faster with any vehicle you drive/ride.

Fraudulent Mails

Most of you have been receiving mails, claiming lottery or fund transfer or direct job offer. And in return they ask your personal information and/or some money to be deposited to some account.

I too have got some of them. Even one complete letter from RBI (as they claim).
Please don't be greedy and never respond to such mails. And be careful if you really want to (in case you are desperate for job).

You may check following if you receive any such mails.

1. The e-mail Id : You will never receive mail from the organization.Organizations have e-mail Id's as <person-name>@<organization>.com or <department>@<organization>.com
And if you observe the mail id for Fraudulent mails, it will be most likely the <Oraganization>@<some-domain>.com.
Following is one of those mails I have received and you can see the mail id, that is not from coca cola.


You can see in above files, the mail address is not corresponding to the format it has to be and the mail was sent via rediff/yahoo.
In such cases avoid opening the attachments as they may have viruses that may damage your system.

2. Address and Names :

Digital Camera : Understanding Specifications

Digital Camera is new generation of cameras that made a revolution and swiped off the old bulky cameras and films from market.
Digital cameras are mainly of two types

  1. Pocket Digi Cameras
  2. DSLR (Digital Single Lens Reflex)
In digital cams normal digi cams and SLR doesn't make the difference like what it used to do earlier when the name came in place.

SLR uses a single lens from where the picture is recorded as well as seen before capturing.
While in earlier normal cameras there used to be a view finder for photographer, and a separated opening with lens for picture to be projected on film.

Now a days this thing is same in SLR as well as digi cam, the same opening gives a view of picture on your screen and you capture exactly what you see.

Now the difference is only a detachable lens in SLR and a little on technology inside. Ofcourse there are more functions.

So before buying learn about below points.

  1. F Number
  2. Shutter Speed
  3. ISO
  4. optical zoom
1. F-Number:- sometimes called focal ratio, or relative aperture of an optical system.
It is represented as f/D or some no below f. And higher the value of D, the lower the value of f/D, and so lower is the amount of light can enter. So if you don't understand much details then while choosing a camera always try choosing one with lens that has a lower f no.
for example :- f/2 is better then f/8

2. Shutter Speed:- is not mentioned in each and every camera but is usually there.
The shutter speed is usually important in high end photography, but you should know a little for the type of photography you are going to do with the camera.
Shutter speed means the exposure it allows to enter. So longer it takes more light enters to the camera.
Shutter should be slower for night photography, and for some nature pics taken so sufficient amoutn of light can enter.
But if should be fast enough if you want to capture a sports action, so the light for a single action will enter and will not blur picture with more movements. what the camera modes do for sports or night mode are usually adjusting ISO as well as shutter speed, if its changeable in the particular camera.

3. ISO:- is a standard for image sensitivity. To simply understand its ISO 100, ISO 200, ISO 400, ISO 800 and in some cameras ISO 1200 and ISO 1600 is being provided. More then that are in higher end cameras.
For dark area you have to use it with high ISO i.e 800 or more, which gives maximum sensitivity and a good picture. But if you will use a higher ISO in a bright day more than ISO 200, you picture will be distorted.
While buying a camera you can check up to what ISO does it provide, and upto what is it usable for you.

4. Optical Zoom:- is a zoom using the camera lens mechanics. Which is limited with lens size and optics. The company tries to compensate it with digital zoom. The digital zoom is not that usable, as once taken you can simply zoom the picture on your own desktop, which is called the digital zoom.
Optical zoom is helpful in someway clicking a better picture for a area far from reach, or for a wildlife photography etc.
Usually cameras come with 4X to 10X of digital zoom that is enough for a handy camera. While in SLRs you can always get a better lens for more and more zoom.

Hope you will get a little understanding about the terms of camera specification and it will help you choose right camera.

Surfing speed and downloading speed are not different (Bps Vs bps)

I have heard many people talking about this that downloading speed is less than the surfing speed (usually 1/8th). There is nothing like that. Whatever is your surfing speed, the same will be your downloading speed too. For eg. if your ISP gives you a bandwidth of 2mbps, then your download speed will also be 2mbps and NOT 256kbps. 
The root cause of confusion is the notation of speed. The specified bandwidth ( more generally called as surfing speed) is denoted by bps (bits per second) while all the downloaders denote the speed in terms of Bps (Bytes per second). Even the browsers denote the download speed in Bps. Since 1 Byte = 8 bits therefore if you are getting a download speed of 256KBps then it is same as 2048kbps or 2mbps.
If you are getting even less speed than this consistently then you should check for your connection strength or telephone/data cables. 
To improve the downloading speed you can use third party downloaders like IDM. They will fetch the maximum out of your bandwidth.
