Microsoft extends XP support to 2014

Microsoft Pledges Windows XP Support Through 2014
ref
apparently Microsoft knows the fact that Vista can't replace XP
in the short term
but I don't know why people need XP updates anyway?
I hated XP update, even turned it off to keep the system faster
anyway
hope the "failure" of Vista will bring more and more people to linux :P

annoying softwares :P

ref

1. Adobe Reader
2. Apple update
3. Windows Update
4. RealPlayer
5. Java update
   
6. yahoo toolbar
7. Norton Antivirus
8. Preinstalled software bundles: Sony Vaio
   
9. Outlook/Exchange
10. Flash

it seems that the author is being annoyed by a lot of auto-update stuff
apparently he doesn't know how to turn those off which is feasible
according to his point of view
luckily I didn't suffer from most of them since I'm using Ubuntu
but the only thing I can't get rid of is the slow, huge resource consumed Adobe Professional
I can't find relevant good software to replace it

CS 241 review

# pipe:

• a pipe is a FIFO queue allowing two processes to communicate
• read, write request will be blocked if the pipe is empty or full

# file permission

• owner/group/other: eg. 664: owner+group can read and write, other can read
• read/write/exec(4/2/1): eg. read + exec = 5, read+write=6

# interrupt

• interrupt is a mechanism to improve processing efficiency

# concurrency

• concurrency is the sharing of resources in the same time frame

# asynchronous operation

• techniques to deal with events happened at unpredictable time or in unpredictable order

# advantages of virtual memory

1. address space can be larger than physical address(MainMEM as $ to disk)
   
2. simplify MEM management
   
3. protect address space for each process won't conflict with the other
