> Juggling eggs:
Keeping a lot of state in your head while modifying a program. “Don't bother me now, I'm juggling eggs”, means that an interrupt is likely to result in the program's being scrambled. In the classic 1975 first-contact SF novel The Mote in God's Eye, by Larry Niven and Jerry Pournelle, an alien describes a very difficult task by saying “We juggle priceless eggs in variable gravity.” It is possible that this was intended as tribute to a less colorful use of the same image in Robert Heinlein's influential 1961 novel Stranger in a Strange Land.

Q: "Engineer" vs Programmer

I'm towards the end of first year and I'm studying Software Engineering at the University of Waterloo; I'm in the midst of midterms and I'm thinking if this is really worth it. I know kids that are younger, or even my age; that know how to program better than me, and know a lot more about progra...

Thomas Owens

Ah, a question from the school that teaches software engineering instead of software engineering.

user41796

What do you do with suggested edits like this one? programmers.stackexchange.com/review/suggested-edits/53945

Thomas Owens

@GlenH7 Personally? I'd reject.

user55340

20:04

reject, anon changing too much. They have a registered account, use it.

Thomas Owens

That's not an edit, that's a brand new answer. Perhaps a derivative answer, but a new answer.

user41796

I have seen where new users screw up an edit because they return anonymously. But it makes sense that they can come back as themselves and fix the issue.

Thomas Owens

So, the 5S police came by my cube today.

user41796

@MichaelT I sympathize with their plight, but am forced to VTC as OT -> career | education

user41796

@ThomasOwens how did it go?

Thomas Owens

20:07

Apparently, having books horizontal is a bad thing and they want me to move them to a different wall mounted plastic holder. However, it's very unsecure to hold the weight of books, plus having books in two locations would break my 5S score.

So I'm choosing to ignore them. If they don't want my books to be horizontal, they can give me a bigger cube.

user55340

Ask if you can annex the next cube too.

user55340

"I claim this cube in the name of 5S and vertical books on a bookshelf."

Thomas Owens

Dude. I could.

It is vacant. I could just lay down some tape on the desks and be like "I hereby declare this to be the regional book cube!"

user55340

Thats a pretty thick book to be a cube.

user41796

@ThomasOwens He has to actually enter a chat room first so he gets registered with chat.SE

Q: How to teach pointers to beginners in C?

I'll hold a little presentation about C-Pointers in a small group of people with beginners programming skills, with no CS background. Just people who would like to learn something about coding and prefer a practical hands-on approach. In fact, they are using the C-Language to do so. We are about...

@user120547 I'm in my 5th year of uni so I know where you're coming from

@GlenH7 You're getting this one?

Dr.Elch

Hi. Yes, that question is why i'm here :-)

user41796

Engineering can be a hard path to follow, but if you enjoy the work then it's worth sticking with. And you will likely have opportunities to pursue that your non-credentialed friends won't be able to do

user41796

@MichaelT Oh, I was in favor of the community process. Lord knows I like listening to my opinion, but there are other valuable opinions in here too

user41796

@MichaelT at some point we'll need to nuke the question so you might as well put the user handle in there

user55340

> So I am wondering, how would you approach this topic to make it fun and interesting? Do you have great examples that really help people to understand the concept of pointers?

user41796

@user120547 - you asked "What if we end up working similar jobs as well " and that's a mighty big presumption. I have worked a wide range of roles, and my engineering background has consistently opened more doors for me. Case in point would be my current gig where they hired me to program specifically because of my engineering background.

user55340

user120547

because I seen some people without Engineering or Computer Science Degrees that are really good at programming get better jobs

user55340

20:27

@Dr.Elch thinking about your problem... Pointers are tightly coupiled to arrays making it difficulty.

Dr.Elch

well would you suggest introducing arrays first?

user41796

@user120547 programming is certainly a meritocracy - so the talented folk will / should rise up to a degree

Thomas Owens

@user120547 For one thing, it depends on the company. If you don't have a degree, good luck getting into aerospace, medical devices, automotive...

Robert Harvey

Yeah, there's something wrong with the popup menu, there.

Stack Exchange

Robert Harvey has added user120547 to the list of this room's owners.

user55340

20:28

I'd start with static sized arrays - the on the stack...

user55340

and then ask the question of "what if you don't know how big the array will be at the start, how do you solve that?"

Robert Harvey

OK, that was weird.

user120547

Oh okay, but why is the school teaching you extra stuff about physics, chemistry, and circuits if all you're going to be doing is coding (i know a lot of schools that do this)

user55340

That leads you to malloc (and free).

Jimmy Hoffa

It varies highly. Some believe an engineering degree focuses entirely on process management and control topics and is extremely weak technically. Occasionally but rarely true, though the point is terminology is VERY non-uniformly applied in this industry

user41796

20:29

@ThomasOwens And other fields show a heavy bias in the credentials they want to see for their candidates

Robert Harvey

@user120547 Because you need domain knowledge to be an effective software engineer.

Dr.Elch

true, i could actually do that.

Robert Harvey

It's not enough to just write some code.

You have to write code that models real-world things.

user55340

@user120547 writing code is the easy part.

How to be a Programmer

user41796

20:29

And the better your engineering skills, the better able you are to model the real world

Thomas Owens

@user120547 I made a comment about this before you joined the room. You should pick up a copy of a Steve McConnell book called "Professional Software Development".

amazon.com/…

Dr.Elch

and I'd have a more defined application for pointers. I really want to avoid too much abstraction

Thomas Owens

I have a degree in Software Engineering, but I didn't have to take physics or chemistry (I took two quarters of physics and a quarter of chemistry, though, but others took biology and more recently, image science became a valid course).

user55340

@Dr.Elch The other approach... would be an old school pascal-ish approach and the problem of "what if you want to change 3 variables at once"

user120547

OK that makes a lot of sense now. So as a software engineer, you work on relating real life practical stuff to software..... makes sense

user55340

20:31

You can't return them all back with a single function (without structures, but that leads to later topics)

Dr.Elch

you mean like "oh why can a function only return 1 value"?

right

user55340

So you make a procedure that takes the address of three parameters and modifies them.

user55340

And then that leads you to pointers.

Thomas Owens

@user120547 True. It also depends on your school's emphasis. McConnell denoted two types of software engineering programs: software engineering and software engineering. His two examples were actually your university (Waterloo) and mine (Rochester Institute of Technology).

user41796

@user120547 whereas I have both a BS and MS in non-traditional engineering branch along with a minor in electrical. I took 2 years of physics, 2 years of chem, and some biology.

user55340

20:32

The concern there is that thats not... best practice... its sometimes necessary, but not the best thing.

user120547

yeah i guess my school focuses more on the engineering aspect instead of the software aspect

Ampt

You know, my first real industry experience with a programmer was modifying his tester code. He was writing a test for an embedded system. On this specific system there are 20 high voltage outputs. One of the big parts of this test is to ensure that when you turn one output on, none of the other ones react to it: each has to be independent of the others. So that was his goal. You know what he did?

Wrote one test, then copy and pasted it 19 times, then went through and changed the numbers. It was ugly, but it worked.

user41796

@Dr.Elch I think it requires a balancing act between abstract in order to wrap your head around pointers and then concrete examples to show how it all works.

Dr.Elch

the second approach would focus more on the true character of pointers, which handles stuff in other places, while the array approach may let to the assumption that a pointer is merely an instrument on such structures

user120547

okk stuff is starting to make sense now, Thank you guys so much :) I feel a lot better now knowing that what I'm learning is actually leading to somewhere

user41796

20:33

@user120547 Not a bad thing. I work with a mechanical who understands thermo really well. We do Energy work, so it makes sense and helps him model our clients' problems.

user55340

(btw, you do see why chat works better for these types of questions? - both career questions and the broad 'how to do...' ones?)

Thomas Owens

Whereas you take things like physics and chemistry and other hard-engineering courses, I took software process courses, product quality courses, economics courses...

user55340

A lot of this requires a dense back and forth conversation that Q&A or comments don't do well.

user41796

@ThomasOwens And I'll admit I suffer a bit when it comes to my algorithms and other fundamentals. A lot of that I had to learn after the fact to make up for the lack.

user120547

yeah thomas yours makes more sense, i like your curriculum better :(

Dr.Elch

20:34

i do actually. :-) not sure why i hoped for a clear answer to that question ^^ i had a lot of trouble to figure out which SO Board I should use, since it became so fragmented

Thomas Owens

@user120547 It's not better. It's different.

user120547

yes, i have a stackexchange account already with like a few hundred rep, its just i didn't want people seeing my name asking such an embarassing question

user41796

@user120547 so long as you feel inspired to tear things apart and understand how they work, you'll do well. You should never stop learning from that point of view.

user55340

@Dr.Elch In pascal, we had the 'var' parameter: wiki.freepascal.org/Variable_parameter

Ampt

@ThomasOwens I have a pretty solid mix of both. you didn't have to do any physics or chemistry?

user55340

20:35

Which dealt with pass by value vs pass by reference.

user120547

yeah but i'd prefer yours its more practical

Ampt

(I had 1 chem course, but 4 physics)

Thomas Owens

@Ampt There was a lab science requirement of three quarters of physics, chemistry, biology, or a combo.

user41796

@user120547 bah. I wouldn't worry about that. You sound discouraged more than anything else.

20:38

@RobertHarvey Bam!

Dr.Elch

so using var gives you a call-by-reference
otherwise call-by-value?

user55340

In pascal, yep.

user55340

You could go into explaining "everything so far, we've passed the value of the thing to the function"

Robert Harvey

Ah, good old Pascal. Excellent for learning, but not much else.

user55340

And write a void function that swaps two values.

user55340

20:39

@RobertHarvey My intro class in CS was in pascal. Made it slightly awkward when the next class was in C.

user55340

(and then the next one was in C++ as "we're going to try this OO thingy")

Robert Harvey

I wrote a program once for the Apple II (in Apple Pascal) that had 30 procedures in it. It took 10 minutes to compile. Same program took about 10 seconds to compile in Turbo Pascal.

Dr.Elch

sure i can do that. but in the end of the day i will be required to answre the question: "that's neat, but why do i need it?"

user55340

@Dr.Elch Because then you can pass larger structures around... and introduce the struct in the next class?

user41796

FYI - I just did a stealth edit on user120547's question so anyone can remove up votes if they would like.

Dr.Elch

20:41

that's what i would do with technical people

but I have people that need something closer to a real world problem, they can relate to

user55340

I'd bias to staticlly sized arrays to start with then...

Dr.Elch

fair enough. I begin to think the same... :-)

user55340

and then show what they were really doing with an array and go to variable sized arrays (malloc).

user41796

@MichaelT It's a simpler approach and sidesteps knowledge they may not have regarding functions

pass by value vs reference is a confusing topic for quite awhile.

user55340

@Dr.Elch any other thoughts / questions about the ciriculum?

Dr.Elch

going down the array path would require me to limit arrays to integer arrays.

strings are another can of worms :-D

user41796

@Dr.Elch I don't think you want to introduce them to arrays of strings in C at this point, no

user41796

20:48

Although a single string is a valid exercise to play with

user55340

How abut a: int sum(int *arr)

Dr.Elch

so arrays, then pointers, then strings?

user41796

@Dr.Elch not a bad sequence, no. Gives you a chance to highlight how the variable name for a char array in C can also be used as a pointer.

user55340

Start out with "here's a sample program that reads 10 numbers - lets modify it to print out the sum"

user41796

And pointer arithmetic for char arrays is still somewhat common despite being dangerous once you start supporting unicode

user55340

20:50

and start with input1 .. input10 and how cumbersome that is... and adding it isn't easy either.

Dr.Elch

no pointer arithmetic for those guys for a long time Glen :-)

user55340

So then you make int[10] to store the values instead.

user55340

(but keep the int[0] + int[1] + int[2]) part

Dr.Elch

ok so far a good example

user55340

Then, you move that part into a sum10(int *arr) that works with 10 values only.

user55340

20:51

And then make it into sum(int *arr, int count) to handle arbitrary sized params.

user55340

And then go back to the original program and make it read an arbitrary number of values.

user55340

(pascal flashback... integer[10] was a different type than integer[11] -- you couldn't pass an integer[10] into a procedure that required an integer[11])

user55340

So anyways, now that you've got the arbitrary sized array, you show whats really happening with that int *arr- that its a pointer.

Dr.Elch

hmm but that example would already incorporate pointer arithmetics

user55340

@Dr.Elch Not really.

user55340

20:55

Your'e not doing *ptr++.

user55340

That's where the confusing part of pointer arith happens. You can keep it safely behind the []

user55340

int sum = 0;
for(int i = 0; i < 10; i++) {
    sum += arr[i];
}
return sum;

Dr.Elch

true i can still write it like that

user55340

And then you change to the arbitrary sized version, replace 10 with count and move back to the part where the array is allocated.

Robert Harvey

So you sneak pointers on them without them even realizing it? I like it. Smack! I got 'cher pointer right here!

Dr.Elch

21:02

but how do I explain the notation? :-)

[] vs. *

user55340

user55340

it would be int sum10(int arr[])

user55340

Same notation.

Dr.Elch

maybe I can use the [] notation and later on refactor it to use the * notation to show them it's the same thing

user55340

Yep. The thing to start with is showing the use case first.

A: Strangest language feature

In C, arrays can be indexed like so: a[10] which is very common. However, the lesser known form (which really does work!) is: 10[a] which means the same as the above.

user55340

And then the solution to the problem... just look at all the programs on SO that have int var1, var2, var3, var4, var5 rather than int[5] var

Robert Harvey

that's because a[10] means *(a+10) ... and 10[a] means *(10+a) :) — Michel Kogan Jan 3 '10 at 14:50

user55340

@RobertHarvey Unfortunately, a[b] == b[a] doesn't work in C++ because [] can be redefined.

user41796

@RobertHarvey <shudders> Sooooo dirty.

Robert Harvey

But quite illustrative of pointer arithmetic.

user41796

21:08

I'm sticking with: Soooooooooooo dirty.

user55340

Its more a side effect of how [] works.

user55340

Its not that its dirty... any more than '1 + 2 == 2 + 1' is dirty.

Dr.Elch

holy crap I wasn't really aware of that ^^

user55340

@Dr.Elch Pointers though, they are dirty.

user41796

and 10[a] is really dirty because it breaks the semantic model that's been promised

user55340

21:11

@GlenH7 it breaks how you think of the operator, but not how the operator works.

Dr.Elch

it works because it is still a normal binary operator, but with a strange notation?

Robert Harvey

It works because addition is commutative.

This question may sound dumb, but why does 0 evaluates to false and any other [integer] value to true is most of programming languages? String comparison Since the question seems a little bit too simple, I will explain myself a little bit more: first of all, it may seem evident to any programme...

A: Why is 0 false?

Because the math works. FALSE OR TRUE is TRUE, because 0 | 1 is 1. ... insert many other examples here. Traditionally, C programs have conditions like if (someFunctionReturningANumber()) rather than if (someFunctionReturningANumber() != 0) because the concept of zero being equivalent to...

Yeah, my math background isn't all that rigorous. But I do know about commutation. :)

Dr.Elch

alright guys, I think I have some good new insights what I will do with those people next time. Thank you a lot for your input!

@MichaelT - so did you determine that room owners do not have the ability to give chat privs to under-rep users?

user55340

@GlenH7 There are too many variables in that bit that I'm not sure if it was the rep, owner, or some other issue.

21:28

Fair 'nuff. Sooner or later we'll find another user account to try and validate against

user55340

Still, today was a good day for chat.

@GlenH7 It's too bad you guys don't have a sock puppet for testing

user55340

@GlenH7 how many downvotes would it take to reset @Ampt to 1 rep?

user41796

serial down voting algorithm kicks in much more quickly than up vote algo.

Ampt

@MichaelT More than I have in all my questions and answers

@Ampt good point - go write some more Q & A!

user20683

Various essential algorithms

Ampt

@WorldEngineer are any of those good for creating ascii art lines?

user20683

@Ampt Is ASCII line art essential?

Ampt

@WorldEngineer uh.... yes?

at least for this stupid lab it is

user41796

@Ampt asciiflow.com/#Draw good enough?

user55340

21:43

asciiflow is my favorite.

user41796

I forget who first mentioned it in here

@MichaelT I can taste the bitter, metallic irony...

Ampt

@GlenH7 close. I need to be able to draw actual slopes

like, given two points, draw an ascii asterisk line between them

got the vertical case done

gnuplot?

@Ampt alternativeto.net/software/asciiflow

user41796

maybe draw.io then? But it's not ascii line art

Ampt

gotta be ascii. Really i just need the damn algorithm haha

but I'm slowly making one

user41796

google asciiflow and you'll find the git / github code

user41796

github.com/lewish/asciiflow You're a coder - fix it. :-)

Q: Python ASCII plots in terminal

With Octave I am able to plot arrays to the terminal, for example, plotting an array with values for the function x^2 gives this output in my terminal: 10000 ++---------+-----------+----------+-----------+---------++ ++ + + + + ++ ...

You'd just need a raster line drawing

Q: Command-line Unix ASCII-based charting / plotting tool

Is there a good command-line UNIX charting / graphing / plotting tool out there? I'm looking for something that will plot xy points on an ASCII graph. Just to clarify, I'm looking for something that will output a graph in ASCII (like ascii-art style), so I can use it over an interactive shell s...

user20683

and then just use the value of * in ASCII rather than others

Ampt

oh damn, ascii plotter looks like it fits the bill
