Any fun little facts your profs have shared with you? It's always fun to look back and realize you took alot out of a lecture.
I learnt a lot about how 9/11 affected popular culture music (my elective) and how North American's and North American artists responded.

There's an album by M. Ward called Post War that I think was written in an attempt to mimick the effect that music had after WWII or something. Man what a cool elective that must have been.

- WWII helped spark the invention of the computer (Turing Machine)
- How to count in binary (hahaha)
- Computer chips are created in labs, and they are actually "grown"
- Xerox could have been the ones to introduce what we now call Macs, but they were absolutely retarded

The coolest things I learn this year:
- Computer Architecture ( how to build a CPU from scratch, program it, optimize it - then building memory, optimizing it to use cache's , etc)
- How by putting electronic parts together I can build a guitar amp from scratch and analyze it to reduce feedback etc
- How to build a fully functional server (that can compete a bit with Apache!)

What do you mean by "grown"? Also yeah Apple stole a LOT of their ideas (including the mouse) from Xerox and then IBM stole it off them and made it a standard

The president of IBM at the time even took a picture with the furher Hitler. IBM machines were used to count and organize the extermination of jews, AND, IBM machine technicians from the US had to visit the 'labour camps' once every 2 months for machine repairs. During these visits they witnesses innocent jews being arbitrarily shot and gased. I hope you've all learned something, Think again before you buy a Nazi Machine (IBM). Google it if you think im bsing.

Nazi ideals and practices were spread all over europe and north america.(don't get me started on how anti-semetic canada was) Secondly, I only posted it to teach people something new that they might have not known. The lesson here is that the world has evolved a great length in such a short period of time and I used to IBM example to prove it. The think again before you buy comment was meant to be a joke lolz.

Xerox hired Alan Kay to make a better photocopier, and gave him free range of office space, materials, and employees. Instead, Kay decided to create a computer a five year old could run, using WIMP (windows, icons, menus, and pointers (mice). Kay took it to the head of Xerox and they said "What the heck? We told you to make a better photo copier", and didn't run with any of the WIMP interface. Jobs heard about it, contacted the head of Xerox and either paid them, or gave stock options (forget), if he could walk through Xerox Parc (where Kay created all his stuff) and have free range to use anything he saw. Since Xerox didn't want any of it, they allowed him. Yep, he stole it all right.

The lesson here is that the world has evolved a great length in such a short period of time and I used to IBM example to prove it. The think again before you buy comment was meant to be a joke lolz. Many German companies were involved in the Holocaust. Quote:MUNICH - German carmaker BMW detailed Wednesday how it became part of the Nazi system, employing forced labour and concentration camp inmates in its factories during the Second World War.
The company has led efforts by German industry to make amends, spearheading the huge Remembrance fund that paid lump-sum compensation to survivors in Israel and all over Europe in recent years.
It and MTU, the aircraft engine company that grew out of the former BMW aero-engine arm, jointly commissioned a historian, Constanze Werner, to study the corporate record during the Nazi era. She worked on the topic for six years.
Her book, "War Economy and Forced Labour", was published Wednesday, and joins other studies of how BMW helped the Nazis arm Germany.
"The book describes the process by which BMW got steadily more involved with the Nazi regime and its crimes, to the point where it deliberately employed forced labour and concentration camp inmates," Werner said.
The Nazis press-ganged people from France, Poland and other nations to work in German factories at low pay in bad conditions. There's no reason to hold it against the companies now. Nobody involved in any of those acts is even working for the company now.

What do you mean by "grown"? Computer chips, CPUs, etc. right? In order to make a computer work, they need to create a chip, an integrated circuit. In order to do do, they use this weird process (semi conductor something or other, didn't write it all down in my notes). They take a wafer of sorts, I think made out of silicon, and it is grown into a crystalline solid form. I don't know how to explain it, but you could wikipedia it for sure. That is why the good computer chips are so expensive, because hardly any of them finish without any defects from the air they are being produced in.

Google it if you think im bsing. The first "almost computer" was created by a guy hired by the British Government, named Allan Turing. The Nazis had created something to help them write code, called the Enigma Machine. It consisted of different gears, and the way they were set dictated what each symbol actually meant. Thankfully, an enigma machine was stolen from the Nazis, and Allan Turing was able to create something that could test out all the possibilities and find the right setting, since the code was changed every single day. He created a long tape, and some kind of moving device, and an eye that could read what was on the tape. Each cell on the tape could be read, changed, or deleted. It is now used as the minimum definition of "real" computers, all other computers can be broken down, "Turing Complete". If you ignored efficiency, the Turing machine could simulate any other computer. Just like your other electronics w/ chips in them can. Ultimately, it came out a while back, that the British Government knew about when and where the majority of attacks were going to happen, after they cracked the Nazi code, but they couldn't prevent them because then the Nazis would know they broke the code.

Yeah I know how it is made, not sure why your teacher would tell you they are "grown" Most of these circuits are made by billions of transistors (created by doping silicon to create n and p-type substrates). They are expensive because to create that FIRST silicon wafer it costs appx $5-10 MILLION to create (it acts as sort of a mold where millions of chips are then replicated from it) and this is only for ASIC design. That's why professors at UofT are trying to push FPGA's because you don't need to create that first wafer. You can just program your hardware using Verilog to "become" any circuit that you want!

I know nearly nothing about computers and how they work, so everything he told us kind of flew over my head. I took the liberty of using the term "grown". My bad.

Haha no worries, I thought I just missed something! OH another cool thing I learned today was how to hack computers at a very deep level LOL Here's how it goes down to people who care: When someone writes a kernel for an operating system they might use some bad progamming techniques (i.e. creating a static array char[256] to hold a packet of data) A static array is held on the stack of a computer, and basically if someone wanted to hack a computer what they would do is send a packet of data that is larger than 256 characters, it would be an overflow but would not crash, it would go farther into the stack then is allocated for that array and with that if the hacker knows how the system is built, they can rewrite the PC return address in the stack to point to an instruction that they want to execute! Executing instructions from the stack also automatically executes is at a root so you have full access to the computer! I know this is probably way over everyones head but I was like a kid in a candy shop when I heard about this lol

Hah, it actually makes sense. And is rather creepy at the same time. Pardon me while I go change my major lol.

One of the best tips I got from my profs was to find any textbook brother site. Its a website dedicated tot he textbook, its lessons and practice quizes. The majority of the profs take their questions from it or their teacher manual but the questions on the site correlate with the teacher manual.
