#Lisp is the $4!7!!!

Who's Using #emacs with #evil

I took it out and when I went to put it back in, I notice there are 65+ packages that start with Evil* I have put evil back in place. But do I want these others?

@billstclair you around?

@billstclair Hey, got that installed. Works pretty slick. I have a few semi-questions if you have some time.

I guess, while I am at it, which #lisp #commonlisp should I settle on

#ClozureCL, #GnuCommonLisp #gcl, #Clisp, #SteelBankCommonLisp (#sbcl)

#spacemacs ... sell me.

I have started to do a bit more #isp and lisp like language things. This just generally pushes me into the #emacs world (just feels wrong doing lisp stuff in Vim). But if I am going to gear up and retool Emacs to use, maybe it is time to reconsider Spacemacs.

I am open minded enough to consider facts in making a decision. :)

Just to clean it up a little, and add some more entertainment.

Okay, here's one with a story :) Let's see if this is entertaining enough :D

Here is a problem that involves being jerk.

You receive a parking ticket and decide to pay in the least
convient way possible... change. This decision comes to mind
because the tickets are in strange amounts because they use
the cents portion for some kind of internal encoding.

You decide to pay all in pennies but when you start to collect
them someone informs you that although change will be accepted,
if the counts of coins exceed the quantities required for a wrapper
then you must roll them. You also figure out that collecting all
these coins is a bit of a nuisance for you. So your goal is to
reduce the overall number of coin rolls while maximizing the
number of free (or unrolled individual coins).

US Coinage count to a roll
0.01 = 50
0.05 = 40
0.10 = 50
0.25 = 40
0.50 = 20
$1.00 = 25 (small) or 20 (large)

Question 1.
How many rolls and free coins of each can you provide to pay your
$100.37 ticket in order to use the highest count of unrolled coins
while using the least number of rolled coins?

Considering that a ticket can cost anywhere from $1.00 to $250.00.
You start telling everyone else about your plan and they decide to
play too, so you calculate how they should pay as well.

To make things a little more interesting, you show up at a city council
meeting and propose that because of the time involved in processing
unrolled coinage that the parking authority should, rather than
bother with unrolled coins, all unrolled coins they collect should
just be donated to the city coucil's general fund. They pass this
unanimously.

For example, 45 pennies 21 nickles for a $1.00 ticket might be
pretty obnoxious :).

Question 2. Which fine amount (in that range) would allow you to
provide the highest number of unrolled coins?

Question 3. The parking authority figures out what you are doing
and decides to change things up by hiring you. Your job is to
determine the best fine values to get paid in the least amount of
unrolled coins. What are those amounts what are those amounts (still
within that range of $1.00 to $250.00)

@namark that one is simple, why not give this a try:

@Lossberg by the way, I do a #toyprogrammingchallenge here, you can look at the origination of it all the way back the 'Ninety-Nine Bottles of Beer" challenge. https://qoto.org/@Absinthe/102805659580967435

Feel free to play at any of them that interest you. There is no timebox on these. Watch for the tag #toyprogrammingchallenge and include it on any answers you offer to any of them.

Okay folks, this should be simple, but maybe not.

The goal is to write a function that takes a positive integer and returns a list of its prime factors. So if you did 12 you should get the list [2, 2, 3]

As neither 1 nor zero are prime, as a result should return an empty list.

This is taken from a #tdd #Kata, so if you have not done this one I encourage you to do so. If you are not into #TDD then solve it however you like.

Is anyone interested in, or has anyone been a part of a programming or coding club?

#tdd #kata #vim #python #testfirst

This is for python, but could be easily tweaked for any other development system.

Your suggestions and opinions are appreciated.

If you like to do code kata and you like to use Vim, here is a script that will create your 2 starter files (<kataname>.py and test_<kataname>.py)

#!/bin/sh
#
# kata, a script for starting up a new kata exercise
#
# Given a name for the kata the script will create 2
# files. One with the same name as the kata with '.py'
# extension added to the end and another named 'test_'
# followed by the kata name and '.py' extension. It will
# be opened in a 3 window layout of Vim with a vertical
# terminal to the left in which you can run 'pytest' or
# 'python -m unittest' or whatever appropriate runner
# you use.
#
# If these files don't alreay exist they will be created
# with an import , and basic docstrings.
#

if [ $# -eq 0 ]; then
printf "Usage:\n\t $0 <kataname>\n"
exit 0
fi

if [ ! -f "$1.py" ]; then
printf '"""%s module."""\n\n' "$1" > "$1.py"
fi

if [ ! -f "test_$1.py" ]; then
printf '"""Unit tests for %s module."""\n\n\n' "$1" > "test_$1.py"
printf 'import %s\n\n' "$1" >> "test_$1.py"
fi

vim -c ':vert topleft term' -c 'wincmd p' -o "$1.py" "test_$1.py"

TDD is awesome. #TDD is anyone out there using TDD? Anyone learning to use TDD? Do you want to?
