you can use
$gcc -S test.c
to compile c code to assembly code(might be at&t style)
then will transform into test.s file
$as test.s
can compile test.s to machine code for execution

evolution of OS and Computer Generation

Generations:

1. 1945 ~ 1955: Vacuum Tube, Plug boards
   
2. 1955 ~ 1965: transistors
   the primitive concept of OS appeared, known as Batch System
   actually, the concept of batch system originally are from the assembly line
   and was first implemented to punched card systemthen came to the
   popular command line interface today on workstations, but the difference
   is that only one process, one shell running, tasks must be done
   one after another(batch)
   
3. 1965 ~ 1980: ICs
   since the complexity of computing is rising ICs became more and
   more popular after it's creation
   
   the concept of OS, has evolved almost completely at this stage:
   batch -> Multiprogramming -> Time Sharing
   Multiprogramming:
   
   • on Batch system, we can only do one thing at a time, then people
     came to think about the possibility to do several things altogether
     the concept of scheduling appeared.
     we create several processes and use scheduler take turns
     to running each of them. Since the CPU is so fast that it seems
     that they are running concurrently.
     
   Time Sharing:
   
   • the evolution is the appearance of Round-Robin algorithm
     in the past, processes are non-preemptive(cannot be interrupt)
     so once u encounter a long job, user will be hanging. Round-Robin
     introduce the concept of Time Quantum. once Quantum
     expired, contex switch
     
4. 1980 ~ present: PC
   at this time Main Frame computer being replaced by Personal Computer
   the concept of Operating System are the same but the resources are
   different
   eg. in the past, Main Frame Computer can assign special resource like
   graphic card to some special user
   

Edsger W. Dijkstra

ref

1. The title of his 1972 book Structured Programming, coauthored with C.A.R. Hoare, became the term used to describe a major style of programming in computer software.
2. He was also known for his low opinion of the GOTO statement in computer programming, writing a paper in 1965, and culminating in the 1968 article "A Case against the GO TO Statement"

Mutex and Semaphore

concep ref

implementation ref1

so mutex is more efficient, in other words, it takes less overhead!

and there's sth about semaphore ref

semaphores
    A semaphore is a special counter.  It has an initial value and two
    operations, P and V, for changing that value.  (P and V are
    initials for words in Dutch; think of them as Pause and something
    else [Voice maybe?]).  A semaphore keeps track of the difference
    between the number of P and V operations that have occurred.  A P
    operation is delayed (the process is de-scheduled) until #P-#V <=
    C, the initial value of the semaphore.

picasa

1. download
2. $ sudo dpkg -i /tmp/picasa_2.2.2820-5_i386.deb

maybe cause it is implemented using wine
so the functionality is not very good though

mic and speaker

gnome-volume-control // for gnome session
or
alsamixer // command line
use "left right key" to choose from different options and up and down to control the magnitude
"m" to turn on/off
"Tab" to change different pages of setting

1. representing readings
    learned rhetoric triangle: rhetor(author, eyerman),
  text(subject) and audience. we need to think about this
  relationship while reading or writing
    from Consumer's gazes, there's three rhetorical
  practices:
  Logos: logical argument, appeal to reason
  Ethos: ethical argument, appeal to rhetor's ethical character
  Pathos: emotional argument, appeal to audiences' emotions
  the point is to sell their ideas!
2. representing your world
    the example of making a map, told us that the world are
  representing in the way the maker wants it to be.
    from Familial Gazes toward photographs, we know
  that beyond description, interpretation is also important
  and the interpretation will change over time.
    we also looked through some photos using
  Documentary Gazes and found out that the world are
  documented in the way the documentarians want it to be.
    what is truth? truth are hided behind different aspects
  and you have to discover it by yourself. :P
