Andre Dublin said:

Looks good, how did you come to the number on line 2 in https://github.com/narendahr15/coursework/blob/master/ex1b.rb

Nice to see some C code in there :)

If you didn't know Ruby is an interpreted language like PHP in C

Also you should put some space between your '=' operator and your vars for readability.

Rhodee said:

please try adding github to your list of safe ssh domains.

This can be done with

ssh -T git@github.com

SSH will bark-no worries: simple accept the prompt with a 'y' or 'yes' if you like typing.

After that check your ssh permissions to ensure your key is actually being picked up by your system:

ssh-add -l

Please post the results of both commands

Hi,

I've done the first three excercises in chapter 1 (the chocolate one was too silly and I didn't understand the last one :/ ).

All the best,

Oh, and here's the ones from chapter 4:

Andre Dublin said:

Looks great. For formatting of your code you may want to put some space between your '=' operator and your variable so other programmers will be able to pick up what you have written.

Krister Löfgren said:

Yes, that would make it more readable. Thank you, Andre.

Exersice 1, should be:

Havn't figured out how to delete the other as yet.

Andre Dublin said:
To delete files from you repo you can do this

$ git rm <filename>

or if you want to remove files from your repo but not delete it from disk you can do

$ git rm --cached <filename>

So far everything looks good, as for your age in seconds problem. Use ruby to calculate your age to seconds instead of thinking about the answer. Let the computer to the work for you.

Hint

Age / Days in Year / Hours in Day / Seconds in Hour

Tony Shaper said:

Hi I have just uploaded the first weeks exercises to Github. Location is

https://github.com/cylons/coursework Sorry it's a bit late.

In the first exercise I have used constants for hours in day etc. According to my Ruby book constants should start with capital letter and "unlike most other programming languages" are mutable i.e. can be changed. I find it slightly amusing to have constants that can be changed.

It reminds me of the old programmers lament "Constants aren't and Variables won't!"

Any comments welcome.

on March 20, 2012, 4:50 p.m.

Andre Dublin said:

Looks good Tony. Your right about the constants in ruby, its best practice to let those values remain unchanged.

The best practice method of writing constants in ruby is this

MY_CONSTANT_VARIABLE

aka screaming snake case

not

MyConstantVariable

aka Camelcase

Camelcase must be used for classes and modules

check out the ruby-style-guide

Peter Hwang said:

I'm having some trouble adding my program to the coursework using git. I'm really new to all of this so I'm probably just doing something dumb.

Basically, I'm trying to add my week.rb from my documents folder to the coursework. Check out the error I'm getting below. Any thoughts?

Command I am running:

Peters-MacBook-Air:coursework hwangpet$ git add /Users/hwangpet/Documents/Week1.rb

Error I get:

fatal: '/Users/hwangpet/Documents/Week1.rb' is outside repository

on March 18, 2012, 11:18 p.m.
Andre Dublin said:
It looks as if Documents isn't a working git repo. My suggestion would be to do this:

1) Navigate to your Documents folder, then run this command.

$ git clone git@github.com/hawngpet:coursework.git

This way you have a working copy of your github repo on your harddrive.

Now you can perform the usual workflow

$ git add . or $ git add filename $ git commit -m 'your message' $ git push origin master

Hi everyone!

Please find my week one assignment here. Please ask me questions. I am not exactly a complete Ruby nuby, but I certainly am not that far from the beginning. Besides, being new means you can ask all kinds of questions =)
