Обработка исключений в Kotlin Coroutines

Представьте классическую ситуацию: вы запускаете корутину для фоновой задачи (например, сетевого запроса) и хотите подстраховаться от падений. Как бы мы сделали в синхронном коде — обернули бы в стандартный блок try/catch блок кода, в котором может быть ошибка:

🎉 Wow, #Wasmtime 47! 🎉 Apparently, after years of blood, sweat, and tears, we can finally throw #exceptions and collect garbage like it's 1999. 🤦‍♂️ For anyone who thought adding more features would make Wasmtime simpler, congrats, you played yourself! 🏆

It's #Canadian #census time again! Seems like we just did this 5 years ago. My how time flies.

The #online version doesn't work for me - no surprise, governments rarely take any #exceptions into account when designing #processes, so I run into stuff like this all the time. So like last time, I go to request the paper version of the #questionnaire, and ... you can't. Not online. Not self-service, anyway.

Even if you go to start the online version and get errors, there's no "send me a paper version" link or button anywhere. The only option mentioned anywhere (hidden away in the FAQ that no one will read) is to *phone them* to request a paper version.

Ya, not happening. So used their "chat now" function, and it's #automated, and it can't help either, only repeats what you already know. Curse at it a bit, and it asks if I want to talk to a human agent.

Yes!

"It's out of business hours, there's no one to help you, goodbye, #chat ended."

Hoookay... so wait until today during business hours, open the chat again, and ... it takes me back into last night's chat. The one that's ended. And that you therefore aren't allowed to send any more messages in. The "end chat" button doesn't work, because it's ended already. No option to start a new chat.

Excellent work, boys, no #notes!

I had to clear cookies to get it to work. How's *that* gonna work for "click the colourful circle to go on Facebooks" crowd?

So I get to wait a week, then make some census workers sad.

Unchecked exceptions in production:

try {
DateTimeFormatter UTC_PARSER = ...
return UTC_PARSER.parseDateTime(date);
} catch (IllegalArgumentException e) {

2023 commit where I replaced joda.time with JDK builtin.

- return UTC_PARSER.parseDateTime(date);
+ return Instant.from(UTC_PARSER.parse(date));

No IDE, no compiler told me the fuck that the **unchecked** exception had changed to DateTimeParseException. Crashed today.

I’m working on adding some support for Haskell exceptions to agda2hs. I needed to do something so make throw not break soundness so I added an (erased instance) argument of some postulated type MayThrow exc, essentially making all exceptions be checked exceptions on the Agda side.

I know there’s much nicer ways to exceptions in dependent type theory (i.e. exceptional type theory by PMP et al) but given that Agda doesn’t implement that, this seems like a decent first step. I’m curious to hear any comments you have!

Programming in MicroPython is interesting, in multiple ways.

If you're not familiar with it, it's a port of the Python language to run on very small systems - primarily microcontrollers of various types. Programming for any of these types of systems, in any language/environment, always poses some challenges because of the limited resources. Forget 32-bit machines limited to 1GB of user-mode address space - think 256 KB of RAM being unimaginably vast for many MCUs, even today.

They did a pretty amazing job getting Python to run on these MCUs. It even supports a lot of the standard library, with restrictions, limits, and various missing bits an unavoidable side-effect.

The specific things that have tickled me about it recently include:

* Missing stdlib modules that a modern Python programmer just takes for granted.

* Don't do more than basic type hints / annotations, because MicroPython won't like them.

* Get used to running into out-of-memory errors if you build lots of complex data structures at runtime.

* Some of the more modern features and syntax aren't supported.

It actually feels kind of like programming in Python 1.1 or so did. I haven't checked, but it wouldn't surprise me if exceptions were strings 😉

Любовь, смерть и жизненный цикл: считаем, сколько люди проводят времени в вашем Android-приложении

Приветствую всех заглянувших трудяг! Помните, как вы готовились к первым собеседованиям на должность Android-разработчика? Жизненный цикл, пересоздание Activity, коллбеки ЖЦ: все эти понятия хорошо знакомы каждому молодому специалисту в нашей с вами области. Однако одна из прилетевших от аналитиков задач на отправку событий, связанных с длительностью нахождения пользователя в приложении, ввела меня в ступор, заставила провести небольшое исследование, проявить чудеса ведения переговоров и узнать много интересных нюансов. Об этом увлекательном путешествии сегодня расскажу вам я, Александр Лебедь, Android-разработчик Core команды приложения WB Partners.
