The Do's and Don'ts of Error Handling • Joe Armstrong • GOTO 2018

Joe Armstrong - Principal Inventor of the Erlang Programming Language
ABSTRACT
Handling errors in programs is tricky.
We want to write systems that work reasonable well even if there are errors in the code. This is possible, and the results have been used in production systems for many years.
This talk outlines the do's and don'ts of error handling. Things you should do if you want to write fault tolerant code, and things you should not do.
I will argue that making fault-tolerant and scalable systems is possible if you [...]

RIP, Joe Armstrong; I learned about you too late, but will certainly study your work.

"Kubernetes--" Joe: 'Who? Who's that?' LOL

What a fantastic mind. Sad to hear about your parting, Joe. The world was better with you here.

@JeremyAndersonBoise 5 років тому

Esdras Mayrink oh no! I am so sad to hear this news. The world is darker without him, surely. Rest in peace, Joe.

RIP Joe Armstrong your work made significant impact on software industry

Wrap your main/entry point in a try-catch and pretend like nothing bad is happening.

Rip Joe!

Amazing talk, a shame the sound is so bad...

@koredeaderele1666 5 років тому

the emphasis on "messaging" in OOP, makes it seem like there's a lot more inherent similarity between FP and fundamental OOP

@JeremyAndersonBoise 5 років тому

Korede Aderele; I believe that’s because almost everyone misapprehends the historical essence of OOP as described by Alan Kay. OOP is about messaging between objects, not about instantiating Classes.

@AlNewkirk 3 роки тому

Fwiw, OOP doesn’t prescribe encapsulating state. That’s just how most people do it.

Smalltalk actually did Erlang style message passing. (Joe says I was wrong.)

If Joe isn’t among your heroes then you’re still a junior dev.

Joseph Leslie Armstrong (27 December 1950 - 20 April 2019) was a computer scientist working in the area of fault-tolerant distributed systems. He is best known as one of the co-designers of the Erlang programming language. Died‎: ‎20 April 2019 (aged 68) :/

if the concepts he is talking about here are foreign for you, then you are a failed developer, enjoy your salary and don't make the community a toxic place.

'The type system doesn't tell you that "open a file, close a file, read the file" is incorrect'.... well, a good type system has a different type for open-file and non-open-file.

@lepidoptera9337 Рік тому

Type systems can't prevent people from being stupid. If you are trying to reduce programming to the art of hiring people who can't program as much as "Hello World!" to reduce hourly wages, then you are in for a bad surprise.

Concurrency is the execution of independently executable tasks. It doesn't mean they all are executing at once...

@JeremyAndersonBoise 5 років тому

Christopher Stamp a fact not lost on Mr. Armstrong. Was your comment a shallow criticism, or did you have a deeper observation to make?

@nobodygone1763 3 роки тому

If you want to get pedantic even if you neglect the fact that the model and runtime he's promoting satisfy both properties because concurrent tasks are performed on multiple cores. Even if he's using a single threaded event loop on a runtime with a GIL because he's running the code on multiple machines it is still both concurrent and parallel. Honestly in general when it comes to nerds the ones who are super invested in pedantry and jargon are full of shit or are just OCD and hard to work with.

The word "do's" is not correct. If it was, why isn't its counterpart written as "don't's"? The answer is that an apostrophe is not punctuation to denote plurality.
