Either you ended up with a job that doesn't need them or you don't have one. I use them daily and stuff from just about every other math class I have ever had.

I agree. So many times people have said being a computer programmer is very math intensive and I don't hardly ever use any math besides basic stuff.

Because you need to learn at a level that is 1 or 2 times higher than you actually need to do your job. That way, what you do is easy in comparison. I was great at math and my instructor said that I did not need to attend his class - just show up for the tests. It is another example of forgetting more than the kids ever knew. I have found it amazing that people need to calculate the Big-0, because it is obvious that a loop inside a loop (inside a loop) is not efficient. But, it is always nice to have a mathematical proof; even if they do not understand it. Do I calculate the Big-0 on my algorithms? No. Do I use calculus? No. Do I use Algebra? Occasionally. Do I remember how to calculate the area under a curve. No. Have I used math on a daily bases to get the job done? Yes. Have I forgot 90% of what I learn. Yes.

There is a 2% chance that the next card will be a 2. I fold. There is a 100% chance I will have less money today than yesterday. There is a 2% local tax that is applied after all other taxes have been applied (taxes on taxes). But only if you are in an area where that applies; otherwise it is applied before other taxes are applied. Actually the last one was a while ago and a supersize. It is amazing how many ways a government comes up with to take your money. 1 part sugar 2 parts butter 4 parts flour Blast, I am out of tea.

I hear you - and when I do use math-like stuff it's more along the lines of set theory and lambda calculus - more Alonzo Church, less Euclid. =)

That reminds me of the first program I created. An algebraic graphing program. Recursive algebraic math parser, low level graphics drawing (before Windows) and a complete windowing system. I am lazy. I would rather spend days creating a program to solve a problem than spend spend hours to solve the problem today and tomorrow and the day after tomorrow. Input/output done.

I do not determine big-O on my stuff either. I prefer to let benchmarks tell the tale. It's yes for me on the others except the last one. The percentage is much lower for me.

Eeeh... well, if you benchmark with a data set of size 10, the one of size 100, one of size 1000 and one of size 10,000, then we might get some indication of how it will perform with at 10,000 size data set. But reality is that most developers who report benchmarking figures do not report for various data set sizes, in a way that lets a user make estimates of the performance will be for other data set sizes. Maybe as common: The benchmarking is done for a small, isolated part of the functionality at the core of the algorithm, with the complexity occurring at a higher level. You proudly show some core operation to be super-optimized, but then you use it in an algoritm causing the number of calls to this core operation to raise exponentially with the problem size: Then the super-speed at problem size 1 may have little value. Understandig complexity, not only in processing time, but also in space requirements, is quite essnetial. You do not always have to calculate an exact O(n), but you should always have a rough idea of the space and time requrements if the data set size is increased by one, two or three magnitudes above the size you used making the benchmarks.

Hmm. I use algebra all the time. Calculus, never. I took 32 credit hours of 'advanced' math in college: calculus, differential equations, and matrix algebra. With only minor forays into matrix algebra when doing graphics, I haven't used any of it. Most of that space in my brain has been recycled for old movie lines. Much, much more useful.

well, when I was working/playing in the field of compilers (long time ago), some set theory was used, however, when designing the different algorithms for the various treewalks (lots of tree walks and list processing) at least one eye was on the big O. Especially for one pass load and go compilers speed was essential (and at that time computers were not that fast) but optimizations were more related to clever programming than algorithms (e.g. the design of a set representation strongly depends on what you want to do with the set and its elements). In my current (hobby) workingarea, software defined radio, both calculus and discrete mathematics are needed. Processing samples - with lots of fourier transforms and some laplace transformations for the filters - is basically calculus oriented. Of course one needs to look at performance: you do not want to miss too many samples, but handling performance is also here more an engineering issue than an algorithmic issue. Translating samples to bits and handling bits is - seen from a math position - different, viterbi decoding is a major component, as is Reed Solomon decoding, the latter using algebra (group theory). But also here, the final performance largely depends - next to selecting decent algorithms - on clever programming and decent engineering. But fortunately, for most of these "math" components there exists libraries (and one can write its own), But, the math, both the calculus and the discrete math, are basically fun to understand and it is always a learning experience to write a library component for it.

I'd like to turn that around since that seems to be the default. So you ended up with a job that does need them. Maybe you're being punished for something you did in a former life, I don't know :laugh:

OK - I get it - falling off to sleep whilst lustily counting sheep doesn't take calculus. However, algebra is really a representation of how we solve problems all day long that have any sort of calculation. It's done as a background process. Now how far goes? Well - do you use all the subtleties of programming you were supposed to learn? Probably not, but you will still claim to have coded (at least in Q&A). Sorry if you lost count of the sheep - there go your Welsh Pub bragging rights . . . unless you can exploit 'lost count' in an implied context..
