> At every place X in the following expression, introduce a boolean negation if there isn’t one (or, equivanently remove one if there is), and

I think it should read:

At every place X in the following expression, introduce a boolean negation if there isn’t one and remove one if there is, and

Maybe even better:

At every place X in the following expression, introduce a boolean negation. If you get two concecutive NOT's, they can be removed.

Next, I don't see how

  timespent <= duration
is the negation of

  duration > time_spent

?
A shift is faster than an add.

Amazing that apparently noone just realizes that 136 is less than the double of 70.

I once needed a special blade for my saw. They only offered a 3-pack so I ordered that, and received 3 3-packs.

I don't know, but I felt that I should report it. Fiddled around for som time on their reporting pages, but absolutely no way to report that kind of error.

Are you in my neighborhood? You can have 3 saw blades for one GG1000 ;-)

Re:Ask HN: Looking for Thesis Project Inspiration on Tuesday December 05, 2023 @05:29PM (#38537813)
Go for what you already have. Use your supervisor to cut and twist your proposal plan to fit 5 months. I don't know where in this world you are, but where I've taught, a master's thesis is about demonstrating what you can do in the time given towards a relevant result. A proposal is a plan. Relevant mileposts should be reached, and the final goal to some extend. But details can be adjusted and cut during the process. A supervisor should help with adjusting the project plan. Up front as well as during your project.

Sure, but "get away with" is not something to strive for in a programming language. I've allways hated C for the unnecessary brainpower it sometimes takes to parse a construct.
"by definition" is a little harsh, and "with an x86 processor" is a little too narrow:

"The designation "PC", as used in much of personal computer history, has not meant "personal computer" generally, but rather an x86 computer capable of running the same software that a contemporary IBM PC could.":

Re:Computation and State Machines (2008) [pdf] on Wednesday July 12, 2023 @05:30PM (#36701956)
Computers are general concrete state machines. Computer programs behave by conducting a computer into a specific state machine behaviour. So it can't be wrong to say that all computer programs describe state machines.
But the point is that you don't actually die then, isn't it? So how can it be illegal?

Re:Finally Getting Two's Complement on Saturday June 24, 2023 @04:20AM (#36456670)
Since the decimal number system is "the" system of all number systems (as we are pestered with it from an early age before our brains have developed suitable abstraction capability until it just becomes second nature) it can be advantageous to think through how tens complement representation works in the decimal number system.
Back in time you could buy a 1-bit microprocessor:

Thanks. Noteworthy:
