@PinkNews @politics-PinkNews It's a shame Charles Davey is a #transphobe, but that is no reflection on his brother, #EdDavey. I'm glad the official #policy of the #LibDems is to oppose the #EHRC #guidelines, & to #support the whole #LGBTIQA #community without #exception. Charles Davey's argument is total nonsense.

TIL Ruby's Exception class has a `detailed_message` method which includes both the exception class and its message:
begin
1 / 0
rescue => e
puts e.detailed_message # => "divided by 0 (ZeroDivisionError)"
endI've lost count of the number of times I've implemented something very similar myself! 🤦

The price of #marijuana is going down because people don't have any money. If you withdraw your #consumerism, you can force a lot of things and you will think differently and you will come up with new ideas that you haven't had before that I bet will be better. Why does #oil appear the #exception?
-
I always ended up at what I thought was nothing. I would take the #exception to the #rule, the new rule, ding ding ding, chase that, and go through the exception to the next rule etc. It always got to what I now understand is the only explanation for everything, the #space. IT IS THAT IT IS.

One of the coolest techniques for writing structured code is to use a decorator. Ruby has a Delegator class (https://docs.ruby-lang.org/en/master/Delegator.html), a DelegateClass method (https://docs.ruby-lang.org/en/master/Object.html#method-i-DelegateClass) and a simple delegation implementation SimpleDelegator (https://docs.ruby-lang.org/en/master/SimpleDelegator.html). If you are really interested in their implementation, you can find the source code here (https://github.com/ruby/delegate/blob/master/lib/delegate.rb).

[Перевод] Почему GZIP сыпал исключениями только в жару и в дождь
В квартире стояла летняя жара. Впрочем, ненадолго: хозяин квартиры как раз привез мне кондиционер, и его пора было запускать. Через несколько недель Я писал на C# программу для распаковки gzip-файлов и неожиданно поймал странное исключение, из которого следовало, что архив поврежден. Ситуация выглядела дико: ошибка намекала на поврежденный архив, хотя сам файл не выглядел реально битым. Сказать, что это напрягало значит ничего не сказать...

More observations about checked vs. unchecked exceptions and why unchecked exceptions should not be called "exception". I rather suggest "explainer". Thy explain why an operation could not be performed.

Terrific explanation of the inner-workings of the #CommonLisp condition system (a powerful superset of #exception handling that can do way more cool stuff, like restarts): https://www.youtube.com/watch?v=pkqQq2Hwt5o
Basically, the condition system itself is built directly in Common Lisp using facilities in the language that are available to the user: dynamic variables, closures, and non-local flow-control (tagbody/go and block/return-from). Nice syntax/structure provided by macros, of course. Fucking brilliant.
