A new version of the firmware can be uploaded to an already programmed device only if the source code of the updated firmware differs from the current version by no more than one character (including whitespace, comments, and newlines) ...

... If these conditions are not met, the update can only be applied to newly manufactured hardware.

This is an urgent message from Head of Technical Engineering Department at X-COM :

We have found a great deal of newly manufactured hardware in our on-site laboratory, it appears it has exceeded our inital expenditures and getting out of control. We are also running out of storage space and had to resort to additional bases from other firmware. **QUICK, SOMEONE PUT A HALT TO IT, OR ELSE WE ARE GONNA FILE FOR BANKRUPTCY ... **

Lua translation

initialValue = 319
decrement = 31

Test Failed
  Expected: equivalent to < 319, 288, 257, 226, 195, 164, 133, 102, 71, 40 >
  But was:  < 319, 288, 257, 226, 195, 164, 133, 102, 71, 40... >
  Extra (1): < 9 >

Why?

Lua translation!

The kata description should state what keycap emojis are, so the user can look for their codes in the kata description instead of digging through the specification.

Missing fixed tests that check for solutions that only check that each line and block has sum 45.

aka this solution should not pass: https://www.codewars.com/kata/reviews/63d317f5d71133047010a3e3/groups/63ddccee4084800001fafe59

The random test feedback is completely useless at pointing out how the actual results are wrong. e.g Tests will give these messages:

Task going to work for 1700ms.
Task going to work for 500ms.
Task exited after approx. 500ms.
Task going to work for 900ms.
Task exited after approx. 900ms.

Test Failed
  Successful tasks mismatch
  Expected and actual are both <System.Collections.Generic.List`1[Worker+Runnable]> with 7 elements
  Values differ at index [1]
  Expected: <Worker+Runnable>
  But was:  <Worker+Runnable>

It's impossible to decipher anything from this mess.
