I was utterly fooled. Looks cool though!
This is a freaking good read.
How do you make these types of interactive websites? (the visualizations changing for different codes)
Bookmarked to read later. Looks interesting from first sight
If I had a nickle for every time I bookmarked to read later and never did...
Your bookmarks must be very interesting... Mind sharing for those of us that are absolute reading whores? (´･ω･`)
What does two's complement mean ? I don't want a comp sci definition per se but like language one, how does saying that make sense ?
It's how you change a number to/from positive/negative.
The basic procedure is to represent the number in binary, invert all the bits, add 1.
How does that relate to the word "complement"
The same how a complementary color is the "opposite" color on the color circle. You invert all the bits to go around the number space circle (mathematically called a "field"). Opposed to normal number spaces this one is a circle since overflowing a binary number (ie all bits being 1 and adding one) will reset you back to 0.
Thanks. that's the answer I was looking for
