DOUBLE YOUR INTERNET BROWSING SPEED ON FIREFOX

Reduce the amount of RAM Firefox uses for it’s cache feature

Try this:

1) Type “about:config” (no quotes) in the address bar in the browser.
2) Find “browser.sessionhistory.max_total_viewers”
3) Set it’s value to “0“;(Zero)

Increase the Speed in Which Firefox loads pages

1) Type “about:config” into the address bar and hit Enter. (Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.)

2) Alter the entries as follows:
Set “network.http.pipelining” to “true”
Set “network.http.proxy.pipelining” to “true”
Set “network.http.pipelining.maxrequests” to some number like 10.

This means it will make 10 requests at once.

3) Lastly, right-click anywhere and select New->Integer. Name it “nglayout.initialpaint.delay” and set its value to “0“;.(Zero)

This value is the amount of time the browser waits before it acts on information it receives. If you’re using a broadband connection you’ll load pages faster now.

Optionally (for even faster web browsing) here are some more options for your about:config (you might have to create some of these entries by Right Click –> New– >Interger or String

“network.dns.disableIPv6”: set “false”
“content.notify.backoffcount”: set “5”; (Five)
“ui.submenuDelay”: set “0”; (Zero)


Reduce RAM usage to 10mb when Firefox is minimized

This little hack will drop Firefox’s RAM usage down to 10 Mb when minimized:

1) Open Firefox and go to the Address Bar. Type in about:config and then press Enter.
2) Right Click in the page and select New -> Boolean.
3) In the box that pops up enter “config.trim_on_minimize”. Press Enter.
4) Now select True and then press Enter.
5) Restart Firefox.

C Program to remove or delete vowels from a string

if the input string is "c programming" then output will be "c prgrmmng". In the program we create a new string and process entered string character by character, and if a vowel is found it is not added to new string otherwise the character is added to new string, after the string ends we copy the new string into original string. Finally we obtain a string without any vowels.

C programming code:

#include <stdio.h>
#include <conio.h>
#include <string.h>
int check_vowel(char);
int main()
{
char s[100],t[100];
int i,j=0;
clrscr();
printf("Enter a string to delete vowels\n");
gets(s);
for(i=0;s[i]!='\0';i++)
{
if(check_vowel(s[i])== 0)
{
t[j] = s[i];
j++;
}
}
t[j] ='\0';
strcpy(s,t);
printf("String after deleting vowels: %s\n",s);
getch();
return 0;
}
int check_vowel(char c)
{
switch(c)
{
case 'a':
case 'A':
case 'e':
case 'E':
case 'i':
case 'I':

printf("%d is a leap year.\n",year);
else if(year%100==0)
printf("%d is not a leap year.\n",year);
else if(year%4==0)

abs Function in C

abs is not a function but is a macro and is used for calculating absolute value of a number.

C programming code for abs:

#include <stdio.h>

Ceil Function in C

Ceil function is used to round up a number.
Declaration: double ceil(double);

C programming code:
#include <stdio.h>
#include <math.h>
int main()
{
double n, result;
clrscr();
printf("Enter a number to round it up\n");

printf("Invalid roman number");
return 0;
}
}
if(digitValue(roman_Number[i]) >= digitValue(roman_Number[i+1]))
number = number + digitValue(roman_Number[i]);
else
{
number = number + (digitValue(roman_Number[i+1]) - digitValue(roman_Number[i]));
i++;
}
i++;
}
printf("Its decimal value is : %ld",number);
getch();
return 0;
}
