In Topic: Can manufacturing effectively be taught, only in the class.

Today, 01:54 AM

I believe that 90% of universities don't teach their students what really manufacturing is, because they don't send them to the factory floor to complement their theoretical knowledge and students can't "see" really from books processes that involve tools for plastics injection machines, presses etc.

 

 

Just in america or worldwide? The college I am in at the moment has massive workshops and machines for making pretty much anything and garages for fixing vehicles and in secondary school technology (a mix of woodwork and metalwork) was mandatory for all first years.


In Topic: Why do we need vacuum tubes, transistors..why not just use DC?

Why even have the power source (wall outlet basically) connected to the VT, and just hook up the power source up to the computer directly, with little logic gates to get it work send 1's and 0's

 

 

Vacuum tubes used high voltages which would fry the logic gates if the power source was hooked up to the computer directly. Vacuum tubes of the time were also rectifiers in that they could convert an alternating current radio signal into direct current which could then be used to record music onto tapes/records.


In Topic: Computer science is not a science!

I feel like computer science is really more of a branch of mathematics than of science.​

 

 

Science is about understanding things. Computer science teaches you to understand how computers work. 

 

You could say computer science degrees aren't really science because at the end of the course you don't understand how a computer works or how to put a computer together yourself.

Implement binary-search as separate function​

 

 

It is even faster to not use a function for it at all. It only saves like 0.2 ms on my computer though. Anyway the addon passed review by mozilla https://addons.mozil...don/beallslist/

chrome webstore isn't accepting new addons at the moment for anything other than chrome OS.

Sort array of urls and use proper binary-search instead of brute-force algorithm.

It will require just 11-12 string comparisons, instead of 2400..

 

 

Yeah that's a great idea. Okay so that is updated to use binary-search.
