travel sickness — motion sickness

Forgetting the passports, getting stuck in traffic jams or packing the wrong clothes can all ruin your holiday. But these problems are nothing compared to feeling sick the moment you start to travel — Dr Rob Hicks.

I belong to the set of people who find it difficult to travel long distances in bus, car, boat or air-plane. What happens is that when I travel in the bus, I feel intense sickness in my stomach and feel depression. I find it difficult to talk to my fellow pessenger or do anything meaningful. All that I think about is — not this time. Please God!! Not this time. I cross my fingers and wish the journey to be finished before I vomit.

This phenomenon, commonly known as motion sickness or travel sickness can be explained as the confusion of mind by two different signals from eye and inner ear about the state of motion. For example, when we travel in a bus, our eyes can not sense the motion of the bus, while our inner ear can sense it. this results in two completely different signlas to the brain regarding the state of the motion, which in turns sends conflicting signals to other organs that results in following symptoms:

[Source: link ]

  • Sweating, excessive salivation, pale skin.
  • Nausea and vomiting.
  • Drowsiness and weakness.
  • Headache.
  • Depression.
  • General feeling of discomfort.

Non-medical Treatments:
Given the syptoms of the problem, it seems logical to me that in order to avoid the problem try to minimize the causes. It implies either a) percept the motion through the eyes. or b) minimize the motion sensed by ears.

[A] Percept the motion throgh the eyes:
1. Keep on looking out of the vehicle. Open the windows/ curtains, if possible.
2. Best is to keep eye-site fixed on the horizon in order to keep sensing the motion of the vehicle.
3. Avoid reading anything while travelling.

note: Option A is not always possible. e.g.:
1. Travelling in the night, or in the vehicle covered by curtains/ non-transparent glass.
2. You must have to read something in the vehicle, or talk to someone inside the vehicle and you find it impoissible to keep looking at horizon.
In these cases, you can go for option B or C. But nothing works better than option A.

[B] Minimize the motion sensed by ears:
1. While travelling in the night, or in the bus which is completely covered by curtains, request seats which are on the most stable part of the vehicle. e.g. In planes the seat over the wings. In the bus, avoid sitting on the seats located just above the wheels.
2. Use your walkman/ iPod/ mp3-player.

[C] Non-medical treatments to travel sickness include
1. Taking slow and deep breaths just before starting the journey. [Source: link
2. Ginger is considerd to be quite effective for travel-sickness. Drink ginger-tea before starting the long-journey.
3. In order to recover fast, keep constant fluid supply.
4. Avoid eating greasy food before the journey.

Braille Leraning.

Learning braille is very easy and it can be very helpful to interact with your blind friends. If everyone in the world read and write braille, it can change the life for blind people. Here is a collection of some Braille learning websites:
Braille through remote learning
Braille Institute
Text to Braille converter

Here is basic braille aplphabet.

Entire Braille alphabet is based on six dots, like in dice, numberd as follows:

1 . . 4

2 . . 5

3 . . 6
These six dots make total 63 characters possible (2^6 – 1 for blank).

Braille alphabet follows a simple algorithm, you do not have to remeber all dots position corresponding to all characters. Just remember dots from A to J. A to J are written in top four dots (1–2-4–5). Rest will derive from them. e.g.:
K to T: same as A to J, except add dot 3.
U to Z except W: same as A to E, except add two dots at 3 and 6.
Trivia: why W is not there? Simple W was not in french alphabet when Baille was invented. W has got a special symbol, invented by Americans.
1 to 0: same sequence as A to Z, but they are in lower four dots i.e. (2–3-5–6).

I read it somewhere that it is easy for people with eyes to learn braille than blind people, as they can cheat. They can see the dots. Invest some time in learning.

Thanks.

Since I posted my experience in installing Suse with 1280×800 resolution on FS VGN-FS115B, I have got lot of mails askign for my xorg.conf file. I thought it is better to put it on my blog:

using 915resolution : reply to mid

Using 915resolution tool is infact very easy. If you read the README file provided with it, you can use it without any confusion. Anyway, here I will write again, for the sake of completeness, how to use 915resolution.

NOTE: You must be root to install 915resolution.
$ su

#915resolution -l [ list all available Modes ]
Intel 915GM VBIOS Hack : version 0.1

Chipset: 915GM

Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1024×768, 8 bits/pixel
Mode 38 : 1280×1000, 8 bits/pixel
Mode 3a : 1600×1200, 8 bits/pixel
Mode 3c : 1920×1440, 8 bits/pixel
Mode 41 : 640×480, 16 bits/pixel
Mode 43 : 800×600, 16 bits/pixel
Mode 45 : 1024×768, 16 bits/pixel
Mode 49 : 1280×800, 16 bits/pixel
Mode 4b : 1600×1200, 16 bits/pixel
Mode 4d : 1920×1440, 16 bits/pixel
Mode 50 : 640×480, 32 bits/pixel
Mode 52 : 800×600, 32 bits/pixel
Mode 54 : 1024×768, 32 bits/pixel
Mode 58 : 1280×800, 32 bits/pixel
Mode 5a : 1600×1200, 32 bits/pixel
Mode 5c : 1920×1440, 32 bits/pixel
Mode 60 : 1280×770, 8 bits/pixel
Mode 61 : 1280×770, 16 bits/pixel
Mode 62 : 1280×770, 32 bits/pixel
Mode 63 : 512×771, 8 bits/pixel
Mode 64 : 512×771, 16 bits/pixel
Mode 65 : 512×771, 32 bits/pixel

NOTE: please notice that 1280×800 is not listed anywhere in the list of avialbale modes. Schade!!! So now you have to change VBIOS settings to include our darling 1280×800 resolution in it. So we have to rewrite some available mode to 1280×800. I know you will feel like re-writing all of them to 1280×800, I can understand the temptation. Even if you do, nothing will happen, but we isght want to use soem other resolution, at some other point in time and space :)). So take one of them, which you hate, I hate mode 38, so What I did was:

#915resolution 38 1280 800

and that is all. Now check whether it really wrote VBIOS or not, do the following:

#.915resolution -l
Intel 915GM VBIOS Hack : version 0.1

Chipset: 915GM

Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1024×768, 8 bits/pixel
Mode 38 : 1280×800, 8 bits/pixel
Mode 3a : 1600×1200, 8 bits/pixel
Mode 3c : 1920×1440, 8 bits/pixel
Mode 41 : 640×480, 16 bits/pixel
Mode 43 : 800×600, 16 bits/pixel
Mode 45 : 1024×768, 16 bits/pixel
Mode 49 : 1280×800, 16 bits/pixel
Mode 4b : 1600×1200, 16 bits/pixel
Mode 4d : 1920×1440, 16 bits/pixel
Mode 50 : 640×480, 32 bits/pixel
Mode 52 : 800×600, 32 bits/pixel
Mode 54 : 1024×768, 32 bits/pixel
Mode 58 : 1280×800, 32 bits/pixel
Mode 5a : 1600×1200, 32 bits/pixel
Mode 5c : 1920×1440, 32 bits/pixel
Mode 60 : 1280×770, 8 bits/pixel
Mode 61 : 1280×770, 16 bits/pixel
Mode 62 : 1280×770, 32 bits/pixel
Mode 63 : 512×771, 8 bits/pixel
Mode 64 : 512×771, 16 bits/pixel
Mode 65 : 512×771, 32 bits/pixel

and lo, old mode 38 is gone to make way for our own 1280×800 resolution. To check it and see 1280×800 for the first time on your machine, restart the X server. I guess init 3 and init 5 will do. —OR— do Ctrl-Alt-Backspace. I know at this time you will say wow!!!

…..Fireworks….....
…..Fireworks…......

So after having enough firework, you will restart your machine to sadle notice that your 1280×800 is gone and once again 1024×768 will greet you back. This happens because 915resolution thing does not permanantly replace this VBIOS mode settings. To do this insert follwoing lines in your /etc/rc.d/boot.local file:

/usr/sbin/915resolution 38 1280 800

and you will never have to bother about resolution buisness again.

GMail and dots

Writing about web page http://gmail.google.com/support/bin/answer.py?answer=10313&topic=133

One of my friend today sent me an email on my gmail account at address ashutoshtrivedi, while my account is ashutosh.trivedi. I was initially puzzeled about what was really going on and then I came across this FAQ from GMail.

Gmail doesn’t recognize dots (.) as characters within a username. This way, you can add and remove dots to your username for desired address variations. For example, messages sent to GoogleAmy@gmail.com and Google.Amy@gmail.com are delivered to the same inbox.

So enjoy sending email to your friends by placing dots anywhere you love to and you dont have to worry about mailerdaemon.

Writing about web page http://www.effingpot.com/

Very interesting website about speaking british english. I like the way author of the website explained minor (and major) differences between american and british english. Specially the illustration with cartoons is quite funny.
