Should Devs know how maths works?

Ideally a dev would learn to do additions in a different representation than decimal.

It's not required knowledge for the average LOB-app. One can work with dates for years without knowing what an epoch is, or the difference between a directory and a folder.

Are you in any way related to our intern? He can't even test a binary flag in a flag word, but is quite sure that you don't need to know about such oldfashioned stuff anymore. His proof for that? There are no classes or methods for this in the framework, so it can't possibly be important.

No, are you? I assure you that in my situation knowing binary math is not very important and has never, ever, been needed.

Hi Guys, I am doing a bit of research and was just wondering... How many programmers know how a computer does math? We take it for granted that those beige boxes (or white, shiny ones in my case :o) know that 2 + 2 = 4, but how many devs know how they work it out? How many care? Should we know? If you know, how did you find out, and when / under what circumstances etc. I learned Boolean Logic in the nineties while working with 68k assembler, and it was a real eye opener. What are the teams thoughts? Danny

x, where x represents the good ones.

Yes. You should also know how to change the oil in your car even if you usually have someone else do it.

They should also know how a computer works, and how the VM or runtime they are targeting works.

What will be the next question, then? Perhaps you could ask some fishermen if they regard knowledge about fish and steering a boat as important. Or ask your reverend wether or not anything written in the Bible is important to him :) Seriously, I was almost moved to tears when our intern (Mr. Framework himself) looked at a hex dump and saw no connection at all to that '1 and 0 stuff'.

What you think should be important may not be important to me or the next guy. I do very well for myself in my profession (on all levels). To slight me because I don't get off on 0's and 1's is lame. Instead of talking smack about your intern and crying about it, why don't you take the time to show this person the connection between the 1's and 0's and why they are important.

There are 10 kinds of people: those who know binary maths, and those who don't. OK OK, exptected.

That's me. I have a two story house, a cabin in the mountains, two cars, and a bitchin' retirement plan and I did it all without knowing binary math. Who would of thunk it? :)

Although "knowing" how a computer does stuff (math, calculations, etc..) is nice, unless you need to know this stuff it doesn't really mean anything to the average developer/programmer. I learned a lot of this in College but have forgotten most of it over the years because I have never needed it...at all. I think "knowing" this stuff is on a personal level...do you care to know it. My thoughts on the subject. :)

Betcha you learned subnetting, too. I've yet to walk into a place having to know any of that...and if, by chance, I ever do have to design a network, I'll use a calculator. Certainly won't try to do it in my head.

Trouble is that they don't. They might know that 010 + 010 = 100, but not the 2 + 2 = 4.

For my part, it was the first thing I learned when I started program, but I have not had to use my knowledge of binary or hex since 2001. I doubt I could pick it up quite so easily now, and as it stands, I'm not particularly worried. I don't plan on writing any code at THAT level anytime soon. But, BUT it would be nice to know I could.

Hi, I have a book called ["Elements of Programming"] and when I was reading your post and question I thought about the back cover of this book were Martin Newell (Adobe Fellow) wrote this: "As a mechanical, structural, or electrical engineer how far they would get without a heavy reliance on a firm mathematical foundation, and they will tell you, 'not far'. Yet so-called software engineers often practice their art with little or no idea of the mathematical underpinnings of what they are doing. And then we wonder why software is notorious for being delivered late and full of bugs, while other engineers routinely deliver finished bridges, automobiles, electrical appliances, etc,, on time and with minor defects" I think we should care and should know about how we can use math algorithms correct and efficient to write better and more reliable software, or at least give it a try

Not strictly true... '010' is as abstract as '2' if you're going to be picky - but I get your point. ;P
