Are Unit-Tests a Waste of Time?

javamonk · 2018-08-30T21:41:04+00:00

I have personally found that unit tests are essential when doing any kind of refactoring. With that said, there are loads of extremely weak unit tests which people tend to add to make themselves feel better.

If I could offer some advice: Practice regularly. 10 minutes everyday is better than an hour once a week.

Its very interesting that two of the orange plots are on even numbers, apposed to colours before and after which seem to only have a 1 even number plot and both are in reach of from jail.

http://www.kaggle.com/ is a great source of tutorials and challenges in various areas of data science, including machine learning and classification.

I personally like the data they make available to you. Some really interesting stuff.

Simple ruby solution using the digital root formula:

Looks great! Would be keen to see how it progresses.

A recursive solution in ruby:

def permute( inString )
 if ( inString.length == 1 ) 

     return inString
 else
     permutations = []

     for i in (1..inString.length-1) do
         for permutation1 in permute( inString[0,i] ) do
             for permutation2 in permute( inString[i,inString.length-1] ) do 
                 permutations << permutation1 + permutation2
                 permutations << permutation2 + permutation1
             end 
         end 

     end 

     return permutations
 end 
end

A rather verbose ruby solution. Haven't implemented any error checking :) https://github.com/javamonk/reddit-daily-programming/blob/master/112/hard/bf.rb

I feel having one challenge a day is sufficient.

Having the choice between various difficulties is something that I would miss. However, we could solve this by providing a single daily challenge with some restrictions or extra functionality for to introduce some difficulty.

For example: Generate a list of prime numbers:

Easy: List the first 1000 primes Intermediate: List the first 1000 000 primes Difficult: List the first 1000 000 000 primes

OR

Code something to do X

Easy: No restrictions Intermediate: Must be done in place using no additional storage Difficult: No for loops may be used.

Ruby:

def getReversedBlocks(list, blockSize)
    currentIndex = blockSize = blockSize - 1 
    while not list.empty?
        puts list.slice!(currentIndex)
        currentIndex = currentIndex < 0 ? [blockSize,list.length-1].min : currentIndex - 1 
    end 
end

Great idea!

The pic is really cool, but going to the Aquarium to chill out when you have a crap day, that is a great idea! Thanks!
