+lesson 1
+
+looking at binary
+ordinal numbers - indexes, counters etc
+natural numbers - start from 0
+intergers - just any number
+rational numbers - just decimals
+
+should learn negative binary and floating point binary
+
+normal multiplication works in binary as well, its just multiplying by 1 or 0
+
+we looked at binary addition and multiplication
+
+we looked at hex to denary
+
+gonna do some programming
+
+
+todo:
+ floating point binary
+ negative binary
+ hex addition and multiplication
+`done!

+4) binary, denary, hexadecimal, octodecimal (base 8) x natural rational integer real
+
+from gcse remember spliting a binary number every 4 bits and convert to hex
+
+when you have signed bit it means - of the bit that is signed (usualy 128) + all the other values
+your colums would be -128, 64, 32, 16, 8, 4, 2, 1
+if you have less bits it might look like this -8, 4, 2, 1
+same for if you have more bits
+
+we did some fixed point binary, it goes like this, -128, 64, 32, 16, 8, 4, 2, 1, 0.5, 0.25..
+it is clear why we use floating point numbers
+
+THE EXAM THINKS THAT 1G = 1000KB
+THEY CALL 1024KB = 1 Gibibyte 
+
+2^n is the maximum amount of values, n = the number of bits

+a standard value will have a ten bit fractional value and a 6 bit exponent (both will be signed)

+the os is a tool designed to make the hardware easier to interactive with, it does this via masking the hardware into easier forms, look at /dev/wsmouse0 for an example
+
+it also needs to make programs easier to write and run, however doing this limits them to the platform they are compiled for
+
+an os may provide apis (/sys on linux) (/dev on openbsd) which allow talking to the hardware and sending signals much easier
+
+there will be a vaiety of different ways of interacting with the os, there is a gui (smelly gui), a tui (better gui), and a cli (the right one)
+
+the os also needs to deal with memory and cpu alication, which ensures the system isn't going to use 100% cpu for a split second while running ls
+
+a virtual machine (in the sense they want me to know), is a disk image, use doas dd if=/ of=/dev/usb0 to make one
+
+the os also manages stuff getting writen to the drives, this is via the file system, on linux it will be ext4, btrfs, etc and on windows it will be ntfs or fat 32/64
+
+remember that translators and compilers come under this topic as they translate to os specific binary files (see man clang for more)

+there are 3 busses, data, control, address
+the data carrys data from the cpu
+the address carrys mem addresses
+the control bus is used to talk to devices about what data to send
+
+von nueman architecture has all the things (cpu mem io) on the same bus
+
+harvard architecture has all the things seperateated on different busses, including mem split into program and data
+
+moddern cpus have a mix of the 2 architectures
+
+the two each have there own advantges
+
+von nueman is simpler overall however it can have limiting speeds as all the busses are shared 
+
+harvard is generally faster as it doesnt have to share any busses, however it can be harder to work with as the developer has to specify which but they are sending data too
+also the extra wires can make costs higher, however this will only ever effect very large scale production
+
+speed is determined by things like clock speed, core count and bus width
+
+a faster cpu may be faster overall, however certan workflows benifit from more cores

+also talked about basics of circuits:
+eg:

+ current flows from posative to negative but electrons themselfs flow negative to posative. 
+ thats being caused by people assuming thing flow one way before mesuring them
+ conventional current reffers to there posative to negative NOT THE FLOW OF ELECTRONS
+
+we also did some practical, where we built a circuit with a bulb
+we learnt how to use the multi meters
+how to:
+ put one input into the com (common port) and another goes into the coresponding wire you want to use
+ 10 amp (probably never used) is the far left
+ mamps is the second from left
+ common is third from left
+ voltage is fouth
+ turn the thing to where it is needed, a wavey line is ac, straight is dc
+ if working with low volts/amps turn it down to mvolts or mamps
+
+we also learnt more about the rest of the course
+notable bits:
+ we will start course work in second year
+ first few weeks is just gonna be gcse recap
+ then something about digital logic, sounds fun
+ sheet about that in folder
+ we will have done some of the second year stuff in year 1 to give us time for course work

+3rd maths lesson, going well so far, we are working on factorizing in the first half
+
+i think we will be doing surds in the second half
+
+the fatorizing is pretty easy overall
+
+for factorizing things like 4x^2 + 4x + 3, you multiply the first value and the last then find a pair of numbers that adds together to equal the middle value, then put them back in individually and factorise the thing
+
+surds does not sound fun
+
+surds arent that bad really, to simplify them split them into 2 factors, one must be a square number
+then square root the square number and move it out of the sign, then leave the remaining value
+
+the lesson was fun, everyone was somewhat interested in the thinkpad, ill have to show them more next lesson
+the guy oposite you knows what linux is

+so far so good with maths, todays work was quite hard however
+
+had to work on some completing the square
+
+also found out how to solve some weird quadratics
+
+if something is like x^6+x^3+2 its still a quadratic
+to solve it you would say let y = x^3
+then rewrite the equation as y^2+y+2
+then solve with the quadratic formula or factorizing
+and then cube root the ans to give it in terms of x for the final anwser
+
+you can only do that when all the powers line up with something that can be divided to match a quadratic
+so x + x^7 + 23 wouldnt work

+writing this late and cant really remember what we did
+we did some work on completing the square which is never too hard, however i should try and do some more work on it
+try and remember how to put something into a completed square form as well as take it out
+
+x^2 + 6x + 6
+(x + 3)^2 - 3
+method is to half B, then subtract b^2, and add whatever is needed to make sure + c works
+
+this can be used to find the turning point of the graph, the section in brackets needs to have its sign flipped
+this is similar to using factorising to solve a quadratic
+the value outside the bracket stays as is
+in the example given the turning point would be (-3, -3)

+notes on day 1
+
+got the bs with rosile and jazmin 
+when we got off the bus met jazmines friend, seemed a bit dull
+got to collage then sat in libary with ben and rosile
+pretty good, maths was not fun but i did it
+see maths/notes/1 for more info
+got out of maths and went to the libary, touched up on cosine rule, practice is in math/NEEDTOKNOW/cosineRule i think
+that makes things feel alittle better
+after that did alittle programing and fixed up the broken algorithum from the line game 
+you should play it to get better
+then had electronics, compared to maths alot better, the teacher seems nice enough, 
+notes on lesson at electronics/notes/1
+got out of collage and walked to the shops, missed the 15:50 will get the 16:50
+currently writing these notes outside ee
+
+todo things:
+ chase up math teacher on the text book stuff
+ learn friends names, there is alex, who is in tutor with you and then the other guy you keep meting, his names not ryan but simailar to ryan
+ considering working on a project to make these notes easier to go back on 
+ relized it will need ls dir in c so it will be something to work on and home then sshcp to laptop
