I wish to meet all of the people who say "math is useless to programmers"

Interesting. The only math I ever used as a software developer is some pretty basic statistics. And I hated statistics as a student :D
When I had to use statistics I understood how much I didn't understand in high school. And I was top of the class in statistics!

Being not anglophone I tend to mix and match UK and US spelling and pronounciation, sometimes willfully (i.e. I pronounce sKedule instead of sCHedule because it's more intuitive coming from Italian). Add to that the fact that Maths is actually singular in italian... I have a strange writing / speaking pattern.

There is nothing strange your about your writing / speaking pattern at all. :)

Every time I'm asked to do some math, I always start at 1+1 and work my way from there. I always like math at school, got good grades even if I was never really good at it, (or felt like it). Anecdotal, I crapped a test on Fourier Transform in one of our Theoretical Computer Science course, We had to do something with it to reduce some equations, but I indexed one of the sequence at 1 instead of 0, it never converged. :rolleyes:

Since I can't figure out superscripting, please read B^2 as B squared ... Let A = B Multiply both sides by B: AB = B^2 Add B^2 to each side: AB + B^2 = 2B^2 Subtract 2AB from each side: B^2 - AB = 2B^2 -2AB (B^2 - AB ) = 2*(B^2 - AB) 1 = 2 QED.

It will depend on what you work with. But I think people that are bad at maths probably make bad programmers, since logics is so important.

Ooh, signal processing? That is cool. Every day is a learning day... recently I had to use Welford standard deviation to calculate a running standard deviation. I did not even know that was possible without storing all of the numbers.

Brushless motor control, which is signal processing (especially when factoring in PWM sinusoids and EM emission control).

I think a lot of the time maths is no necessary in much of what we do as developers, but having a mind that is good at maths does seem to make people better developers. Perhaps it's something to do with being able to work with abstractions or recognise logical patterns. P.S. I do not have a naturally good mathematical mind.

It all depends on the field in which you end up. I think all programmers (who do it as a full-time job) end up acquiring expertise in a domain that is not, strictly speaking, related at all to programming. Mathematics would be one of those domains. Personally, I got shafted when I was accepted to university, provided I took a chemistry course, which they had decided was a prerequisite for computer science - chemistry was the only science course I did not take while in high school. To make a long story short, the schedule for that chemistry course conflicted with my other courses, and neither teachers nor university administration gave a damn; I dropped out during the first semester and went to college for 3 years instead. Decades later, I've never had a job that required any sort of chemistry, and I certainly don't feel like I've missed out on anything.

I wish to meet all of the people who say "soil research is useless to programmers." My client just called me and told me that their indicative beet cyst nematode research does not display the eggs per larva per 100 ml correctly. Also, if I can create a report showing yearly infections of rostochiensis, pallida, or both. Meloidogyne is going pretty well though.

Years ago, in the 1980s, and in a land far, far away, New Jersey, I developed a radar display on a PC for the FAA. Those were the days of the '286 and they were s-l-o-w and floating point was an unavailable hardware option. In order to keep up and display the data in a circle, I had to re-derive the standard SIN, COS, and TAN functions to recognize 0 degrees as the positive Y-axis instead of the traditional positive X-axis. Or, to put it succinctly, how well do you understand trigonometry and integer processing?
