DD-WRT Wireless → Basic Settings differences

There are various options in DD-WRT under Wireless → Basic Settings.
http://www.dd-wrt.com/wiki/index.php/WebInterfaceWirelessBasicSettings
They are as follows:

1. AP (Access Point)
2. Client
3. Client Bridge
4. Repeater
5. Repeater Bridge
6. Ad Hoc

Options explained here:
http://www.dd-wrt.com/wiki/index.php/Linking_Routers

A simulation could be found here
http://www.informatione.gmxhome.de/DDWRT/Standard/V24BetaVPN/Wireless_Basic.html

The difference between them can be explained better using images.

C++ Notes

Bitwise shift operators
The bitwise left shift (<<) (A << B) operator shifts A by B bits to the left. Just add B number of zeros to the left of A in binary format.

E.g.
6 = 000110.
6 << 1 = 001100 = 12
6 << 2 = 011000 =  24

The bitwise right shift (>>) (A >> B) operator shifts A by B bits to the right. Just add B number of zeros to the right of A in binary format. If there is no room to shift to the right, truncate the bits on the right.

E.g.
6 = 000110.
6 >> 1 = 000011 = 3
6 >> 2 = 000001 = 1 (last 1 is truncated)
6 >> 3 = 000000 = 0 (both 1's are truncated)
6 >> 4 = 000000 = 0 (both 1's are truncated)

Pointer initialized to 0
In C++ a pointer initialized to 0 is equivalent to NULL.
So
int * ptr = 0;
and
int * ptr = NULL;
are identical.
But initializing to any number other than zero is illegal.

Uninitialized pointers contain garbage values. Only Static pointers are initialized to NULL automatically by the compiler.

Function declaration place
Functions should always be declared/defined before it's call (from top to bottom). If it's not defined, at least it should be declared before it's call.
You can declare it inside main() as well, but it should be before the call to it, is made.
If it's defined before main, declaring it after the definition or inside main is redundant.

Quiz:
Q. You have 2 ropes, "A" & "B" and they both burn in 1 hr. You have a matchbox. How will you determine 45min?
Ans. Burn "A" from both sides, and "B" from one side. "A" will burn completely in 1/2 hr (30 min). As soon as "A" finishes, burn the other end of "B". "B" will now burn completely in 15 min. So you have 45 min.

Q. You have 9 balls, 8 of them are identical and only 1 is heavier than the rest. You have a beam balance. How will you separate the heavier one in the least number of measurements.
Ans. Divide 9 balls in groups of 3 => 3(A), 3(B), 3(C). Weigh two groups, e.g. "A" & "B". If both are same, the heavier is in "C" group. If "B" is heavier, heavier ball is in "B". Take the group containing tthe heavier ball ("B" or "C"). Divide it in groups of 3 => 1(E), 1(F), 1(G). Weigh two groups e.g. "E" & "F".  If both are same "G" is the heavier ball. If "F" is heavier, "F" is the heavier ball and vice versa. So least number of required weightings = 2.

Non 8-channel LPCM SAD EDID Issues

Capture the Real-Time EDID with moninfo.
You should get something like this



and in your audio properties you would get something like this



Notice that the LPCM has "6-channel" in SAD and the "Max Number of Channels:" in audio properties is 6, these both should be 8
Edit the EDID to correct this value.
Install the EDID override
Monitors should be labelled as "Generic PnP Monitor"





You would get something like this



Notice that "Max Number of Channels:" is 8 now.
