A university-level algebra course typically starts with this kind of material in third or fourth year (it demands a significant comfort level with proofs)

I hate proofs... *shudder*

Actually they are here to make the good programmers shine ;)

Software developer is probably the only job I know where the productivity and performances can vary so widely from one employee to the next..


Very true. They say a good programmer is 20x as productive as an average one. It makes sense though, I've known a lot of bad programmers... In the past, I had a couple of friends who were...  They'd be trying to get certain functionality added in their applications, but the code was beyond them... After trying, and failing, for days or a week, my dad or I would take a look and have it up and running in under an hour. Similar results when they actually got things working, but the time it would take to run processes would be enormous... We'd look at it, and usually have to completely recode it to make it viable.

I wish I had a nickle for every time this happened.  I once was looking through our web site looking for rogue queries that were tying up our SQL server and came across a page the provided an alphabetical listing of all the authors for our magazine.  Instead of writing one query that returned all the authors by last name, the original developer created one query for each letter of the alphabet.  Yes, that's 26 queries. He then output each one of them, one at a time to build the listing. It took 25 seconds to load the page.

And this could have been avoided, if before they'd ever started, they'd simply stopped and asked how much maths is involved in programming.

(And yes, I math has nothing to do with failing to know how an Order By clause works, but I would hope that anytime such a question is asked, instead of answering, the response is simply "DO NOT BECOME A PROGRAMMER.")

4 pages of replies. I guess I'm too late already. By now, you must have concluded that for what you want to do, the level of maths you're comfortable with is adequate.

It could also have been avoided if I had been allowed to beat said developer about the head and shoulders with a blunt object. But alas, my boss would not let me.

Many maths are required. I would advise you to get around 30~35 maths to start.

Your statement makes zero sense.


I feel rather insulted.


I

''many maths'' !?

''get around 30~35 maths to start.'' !?

I can't help pointing out these things. It's in my nature. Those statements sound like a 6 year old's inattentive utterings.


Totally, you don't need 30-35 maths, only a child would think that!  You just need a few really big maths.

And the good thing about big maths is that they're much harder to lose than the little maths.

That's a misconception! It's not the size of the maths, it's how you use them
