Do they do that when hiring mechanical engineers? Make them fix a Rube Goldberg design?

(Memory elements are lookup tables with feed back. Very instructive to deconstruct for example the gate diagram of the D-flip-flop 7474 into one table with five inputs and three outputs.)

I remember that. I've been here longer. It has been a long down-slope.

Years back down-votes were rare on HN. It was relatively easy to infer why a comment was down-voted. Now you mostly can't tell, just wonder why.

Yes. Contemporary software engineering education is like jumping right into organic chemistry without knowing any inorganic chemistry.

Rejected? Not yet. Let's first see if you can get operator precedence right. If plus or minus is followed by the empty string, "10* x+y" must be done first, or what?

Fine, if you can "paint" the full equation on your calculator. But on simpler calculators people may have a hard time getting it right. 3 + 4 = / ( 5 + 6 = + ( 7 + 8 ) / ( 9 + 2 =

We wouldn't wish for the end of humanity, but if it implies the end of inhumanity, it would be a net gain.

Wouldn't that entail that the developers also took on responsibilities for future consquences of the use of their software?

If so then just move it to a natural position. For example in a nostril.

Well, a long line of code could hold a lot of meaning.

I think you just reinvented assemblerprogramming.

From a review comment: The highlight, and in my opinion success, of this book is the fact that no "real" programming language is used to notate any examples. Rather, Dr. Shackelford, along with other TA's of recent past, dev

But it is an operational stumbling block when subtraction gives negative results. It may lead to calculation errors otherwise avoided. In a pedagogical setting like this one error sources should be minimized.

What about using two full keyboards, one for each hand? The question is, will they cooperate? I.e. holding a modifier key one one keyboard affects keys pressed on the other keyboard? If so, I think I would like using two small separate ke

It certainly makes sense for an object encircling you. For a wall clock it then comes down to whether you imagine yourself standing out from the wall on the clock face, or if you are burried into the wall. The first is perhaps the most obvi
