Most processors require specific memory alignment on variables certain types. Normally the minimum alignment is the size of the basic type in question, fo instance this is common

char variables can be byte aligned and appear at any byte boundary

short (2 byte) variables must be 2 byte aligned, they can appear at any even byte boundary. This means that 0x10004567 is not a valid location for a short variable but 0x10004566 is.

long (4 byte) variables must be 4 byte aligned, they can only appear at byte boundarys that are a multiple of 4 bytes. This means that 0x10004566 is not a valid location for a long variable but 0x10004568 is.

Structure padding occurs because the members of the structure must appear at the correect byte boundary, to achieve this the compiler puts in padding bytes (or bits if bit fields are in use) so that the structure members appear in the correct location.

e.g.

struct ex{
int i; //assuming int to take 2 bytes
char c;
int j;
};

Here, size of struct will be 6 bytes because char will use end at an odd location while int j will require it to start with an even location. So, it ends up with padding between variables c and j.

1. Structure padding is adding extra bits at the end of the structue,so that the structure completes the word boundary.

2. padding is allocation of extra bits to facilitate the processor for easy access. And memory (extra) is added after the variables and hence the whole structure gets a fixed size (depending on the machine you are using). You can verify it with the example on the link provided by you.

### How to do mass insert in redis

A basic and fairly easy way to do mass insert in redis:

Command to use: echo -e "$(cat redis_mass_insert.txt)" | redis-cli --pipe Content of file "redis_mass_insert.txt": *3\r\n$5\r\nlpush\r\n$5\r\nu:m:1\r\n$5\r\nvalu1\r\n*3\r\n$5\r\nlpush\r\n$5\r\nu:m:1\r\n$7\r\nmyvalue\r\n Result: All data transferred. Waiting for the last reply... ERR unknown command ' *2' ERR unknown command '$4'
ERR wrong number of arguments for 'echo' command
ERR unknown command '$20' ERR unknown command ' A�j d�Q;yT��ҡ �h>' NOTE: command line will show error but in actual the data is transferred and you can check it by entering in redis. Here's the snapshot of the whole procedure: To check how the command is responding: use hexdump -C Command: echo -n$'$3\r\nset\r\n$3\r\nkey\r\n$5\r\nvalue\r\n ' | hexdump -C whose output will be something like 00000000 24 33 0d 0a 73 65 74 0d 0a 24 33 0d 0a 6b 65 79 |$3..set..\$3..key|

### error in eclipse on import org.eclipse.jetty.server.Server;

When you find error in line import org.eclipse.jetty.server.Server; it means eclipse doesn't contain jetty.jar. Right click on project -> properties on left pane -> java build path right pane -> add external jar under libraries tab link it to all the jar files of jetty folder. can download jetty from : http://www.eclipse.org/jetty/downloads.php now rebuild the project.
