People are posting their Belarc Advisor reports to the web, these reports contain all of the users software keys.

Windows XP CD key list

Increasing Popularity, Great number of choices , Small, Easy, Good and Fall in Prices and the Coolness factor of having one factors have made us to buy one of the Portable Media Players

They let you listen to the music on the go and give hours of battery life and easily charge back again in no time from your laptops.
And They have lots of other features that you know geeks know them much better then a layman out there !

Now a days even a 5k cellphone sports a Descent Music Player and FM tuner !! this adds to it !!

One of the most neglected factor by people is the hearing problems that these MP3 players bring with themselves. This will now be proved .

Presented will the research done by scientists and noise experts to prove the point !!!

The damage to your ears is depends both on the noise level and time of exposure

Sound levels is measured in A-weighted decibel (dBA) units its on a logarithmic scale

which means 2dBA is 10 times 1dBA !! Note This Point !!

Noise level Table
How loud is too loud?
Decibel level What we hear

10 dB Normal breathing
20 dB Rustling leaves, mosquito
30 dB Whisper
40 dB Stream, refrigerator humming
50-60 dB Quiet office
50-65 dB Normal conversation
60-65 dB Laughter Every day Conversation
70 dB Vacuum cleaner, hair dryer Restaurant
75 dB Dishwasher
78 dB Washing machine, High Class Room without a teacher
80 dB Garbage disposal, city traffic noise

Prolonged exposure to any noise above 85 dB can cause gradual hearing loss.

84 dB Diesel truck
70-90 dB Recreational vehicle
88 dB Subway, motorcycle
85-90 dB Lawnmower
100 dB Train, garbage truck
97 dB Newspaper press
98 dB Farm tractor

Regular exposure of more than 1 minute risks permanent hearing loss.

103 dB Jet flyover at 100 feet
105 dB Snowmobile
110 dB Jackhammer, power saw, symphony orchestra
120 dB Thunderclap, discotheque/boom box
110-125 dB Stereo Rock Music
110-140 dB Rock concerts
130 dB Jet takeoff, shotgun firing
145 dB Boom cars

A Flash Based Meter with Noise

Another one check this one too

Music dBA levels

60-70 dB normal piano practice
70 dB fortissimo singer 3 ft. away
75-85 dB chamber music in small auditorium
84-103 dB violin
85-111 dB flute
85-114 dB trombone
106 dB timpani & bass drum rolls
120-137 dB symphonic music peak
150 dB rock music peak

Safe levels beyond which u face risk

80 dBA 8hrs ( but note 80dBA is Considered risky in the long term )
90 dbA 8 hrs
92 dbA 6 hrs
95 dbA 4 hrs ( This is the level @ which people listen to in heavy traffic )
97 dbA 3 hrs ( This is the most common level set by teenagers in presence of 75dBA ambient noise )
100 dbA 2 hrs
102 dbA 1.5 hrs
105 dbA 1 hr
110 dbA 0.5 hr
115 dbA 0.25 hr or le

So the sound level at a normal conversation is 60dBA and if your mom calls you or some one says something to you when you are listening to music and you can’t hear then it means you are listening to music @ 80dBA

Sound Levels about 80 dBA are considered dangerous !! That’s also the sound level of city traffic !! Now If you are listening to music in city traffic then the output of your music player will be certainly more then the ambient sound of 80dbA and will be around 90dBA which is very dangerous when exposure time is long !!

If you think you have “gotten used to” the noise you are routinely exposed to, then most likely you have already suffered damage and have acquired a permanent hearing loss. Don’t be fooled by thinking your ears are “tough” or that you have the ability to “tune it out”! Noise induced hearing loss is usually gradual and painless, but, unfortunately, permanent. Once destroyed, the hearing nerve and its sensory nerve cells do not regenerate!

Noise hearing loss usually starts with high frequencies !!
High frequency sound ringtones are used by students in USA in classrooms !!
Simply Put the Younger Students can hear the high frequencies well but the teacher can’t and hence small kids use these ringtones in the middle of classroom to go unnoticed !!

Getting Back to Sound Levels by Music Players these charts make it clear !
So you can clearly see that volume levels of 60-70 % is risky !!

All combinations of headphones/earphones and MP3 players generate potentially harmful sound levels !

It will take from 12 minutes (at 102 dBA) to seven hours (at 86 dBA) to exceed the occupational noise limit noted above. You will exceed the limit in just one minute if you played heavy metal or pop music at full volume levels of 114 dBA. At this sound level, exposure for longer durations can pose a risk of immediate, serious and permanent hearing loss. !!!

The Bottom Line Is Your MP3 Player Will Damage Your Ears Any Way !!!

Bose that’s why came up noise cancellation headphones for airlines…..remember the ad ??

So when there is lots of ambient noise just shut your music player and save your ears !! And save your a$… you dont want to get dumped by your gf and fired by your bose coz u dont listen to them ( read u cant hear them ) !!

Assumes that you wanna include a laptop and a desktop in ur home wifi network in the first part and share a net connection in the second part. i’m not discussing an ad-hoc connection here. its a normal wlan setup.

ok to create a home wlan you will need the following:

1) desktop wifi pci card/usb adaptor ~rs.1k

2) a wifi access point cum router (which has rj45 connectors to connect at least 1 ethernet cable). price ranges from about rs.2.5k to 5k. select the one which has at least 1 ethernet connector.
3) a normal ethernet cable to configure ur wifi router for the first time and also to troubleshoot. (a cross over won’t do.. it shud be a normal cable.)

4) a wifi enabled laptop or a wifi adaptor (minipci or pcmcia) for a laptop widout wifi feature. ~rs.1k

lets go about configuring ur setup now.

right click on the wifi adaptor in network connection in windows OS (do lemme know if u use linux. proc will be a bit different) on ur laptop. then goto the tcp/ip protocol and enable the manual ip settings. set this laptop’s ip as this: 192.168.1.4. it’ll automatically fill in the subnet mask. do not bother abt the gateway and dns servers at the moment. now ur laptop wifi has the ip address of 192.168.1.4. do the same for ur desktop wifi adaptor properties and set its ip address to 192.168.1.5

u need to configure ur wifi router. if u haf any other device which connects thru rj45 connect then unplug it (e.g dsl modem/router). now simply connect the wifi router to ur laptop (or even desktop) thru the ethernet cable. usually all routers haf a default lan ip address of 192.168.1.1 (refer the manual as to what is its lan ip address if this doesn’t work).

since u’ve connected ur wifi router to ur laptop’s lan connection, goto ur fav. web browser on ur laptop and type 192.168.1.1 in the address bar. it’ll ask for username and password. get these from the wifi router’s manual. after entering those it’ll display the router’s config page. find the category lan/network and find the field that says ip address. it will most probably be 192.168.1.1 (or whatever says the manual). change it to 192.168.1.2. save, exit and then close ur web browser. then launch ur browser again and type 192.168.1.2 in the address. it’ll again open the router’s config page after asking for username and password. now save and logout.

you haf assigned an ip for 3 devices in ur home wifi. u need to secure ur network now. again goto the router’s config -> wireless lan config page. now find the settings that says SSID. this is the network name. u may use the default one or give any name for ur network. note it down on a piece of paper. u may also disable the ‘broadcast ssid’ option to stop the router from announcing ur network all over the place for added security.

now comes the real security setup. there are three types of security algorithms availalbe in modern wifi routers: WEP, WPA, WPA2. i’d recommend selecting WPA or WPA2 as these are more secure than WEP. select either of them and then give a PSK (pre-shared key) in the network/security key option. let it haf a combination of numerals, upper case and lower case alphabets for better security. a key like ser89dME7da1we3 is a good idea! note it down. save, logout, exit…. then log back in the same way to the config page and ensure whatever you did till now (ip changing, ssid, wpa psk etc.) haf been saved. ensure that logout, exit and then unplug the ethernet cable.

goto the wireless connection wizard in control panel in ur laptop. go thru the wizard and select connect to a network. it’ll search for any available wireless connection. it’ll now detect ur router wid the ssid u gave (if the ssid broadcast is not turned off). click on that network and select connect. u may need to key in the ssid in case you’d disabled ‘ssid broadcast’. it will now ask for the WPA PSK. jus type in the same key that u set in the router config page and then allow it to connect to the wifi network. select save connection/connect automatically. you can now see a wireless network connected icon in the system tray. congrats! half the work is done now! do the same for the desktop. double congrats!! almost full work is done now!!!

to share files you need to ensure that the ‘server’ service is enabled in auto mode in control panel>admn services>services. now goto my comp (on desktop), right click on it and selec properties. in the network tab under the computer name jus give a name to the laptop. in the workgroup option, give a name for the workgroup. lets say you’ve given the name ‘mobile’ as ur laptop’s name and ‘myhome’ as the workgroup. note them down. now do the same for the desktop. but ensure that you give a DIFFERENT computer name, say ‘fixed’ to it. however, you need to give the SAME workgroup name to the desktop e.g ‘myhome’. you may need to restart.

now goto my computer/explorer. right click on the folder you wanna share in ur desktop/laptop and select the sharing tab. click ‘i understand…..’ to activate the sharing options. enable ‘share this folder’ option and give an identifier for it. then click ok. u will now see a hand emblem under that folder. do the same for all folders/drives/printers on both ur laptop and ur desktop that u need to share. after that goto my network places/network and sharing (vista), you can now see the other computer/shared folders/printers etc. thats it! u are done!

happy sharing

the next part if for those who wanna share an always on a/dsl connection thru this wifi setup.

setup the modem to autodail mode (router mode, always on). now it’ll mostly be hafing the ip address 192.168.1.1. connect it to ur laptop (or desktop) thru lan cable and type 192.168.1.1 in the address bar. enter the username and password as provided and then got the config page. ensure that it automatically dials and is in always on mode. also ensure that the ip address, subnet and dns are properly setup here. now save, logout and exit browser. disconnect the a/dsl modem from the laptop and connect it to one of the ethernet ports on the wifi router.

some wifi routers will allow you to dial thru them. u can set it up from the wifi router’s config page. but its better not to mess around and connect it automatically by modifying the a/dsl modem’s config page. this will work wid all wifi routers regardless of whether the wifi router supports dialing or not.

you need to configure ur laptop and desktop now. goto the network settings> wifi card> properties (right click). select tcp/ip properties. now in the manual settings you need to fill in the details which you had left blank previsouly. enter gateway as 192.168.1.1 (the a/dsl modem’s ip) and the primary dns server as again 192.168.1.1. click ok.. you may then hafta restart. do exactly same for ur desktop. thats it! everything’s done..

A Biological Virus: an entity that attatches itself to a healthy cell and uses the infected cell to infect other cells

a computer virus works in a similar way
it NEEDS to attatch itself to something before it can infect and spread
there has to be a mechanism to run this virus automatically
this is explained below

Malware: MALicious softWARE, including viruses, worms, Trojans, Denial of Service and other such attacks. Sometimes referred to as rogue programs

Denial of service (DoS) attacks: cause thousands of access attempts to a Web site over a very short period of time, overloading the target site and shutting it down.

Identity theft: is the impersonation by a thief of someone with good credit.

Macro viruses: are viruses that spread by binding themselves to software like Word or Excel.

Malware: is malicious software that is designed by people to attack some part of a computer system.

Worm: is a computer virus that spreads itself, not only from file to file, but from computer to computer via e-mail and other Internet traffic.

How A Virus Can Attach / Two Types of Virii

1.) Boot-Sector Virii: infects boot sector executables. affects MBR’s / Partition Tables .
once its loaded in the memory .. it sits and waits

2.) Macros / Macro Virii: A macro is a series of commands and instructions that you group together as a single command to automate a task.

Steps that should be taken ?

use IE’s inbuilt pop-up blocker and Info Bar (IF ur still using IR and SP2 Required)
tho most of the browsers have pop up blockers now .. for those still on IE and SP1 u can use
MSN Toolbar
Google Toolbar
other software like POP UP COP
in my experience the latter 2 were VERY effective

block activeX components ( set them on ‘prompt’ )

use a better browser like maxthon (still based on IE tho), FireFox, Opera [top 3]

use a firewall.
zone alarm and sygate are good personal firewalls
then in shareware u have
NIS, McAfee’s Firewall and ZoneAlarm the PRO version
personally i think ZAPro rocks … i put my trust in it
get ZAP tips Here

use a good AV . ( this should be a top rankin point but i already covered an AV shootout )

spyware adware removers L like adaware and spybot like bat mentioned
in addition other good ones are
BPS ( Bullet Proof Software ) spyware remover<== i love this. got immunisation for 150 threats for ur browser. Plus inbuilt HiJack This Spyware remover spyware doctor speaking of HJT learn how to use it and use it well here DO NOT neglect trojans … DO Treat them as SEPARATE YET MALICIOUS threats DO use separate Trojan removers like Anti Trojan Shield
