C# 8 introduced async generators with IAsyncEnumerable, so you can combine yield and await in C# as well. Those async generators are consumed using the ”await foreach” statement (which offcourse can be used nested from within another async generator).
Dependently typed languages such as Idris or Agda uses types for validation. Their type systems are also Turing complete, but you are only allowed to use total functions (that do halt) as proofs in types.
I used to work with a medical software where we turned off logging completely in production, to mitigate the risk of accidentally log patient information.
We needed to log that kind of data during development and just tagging what messages were sensitive would have been too error prone, so we couldnt reliably have any logs once we went live.
We did however have a special crash handler that logged the exception type and callstack, but not even the exception message could touch the harddrive.
An non-async Task<int> is returning a Task<int> object, where the return statement of an async Task<int> method is of type int (which will be wrapped in the resulting Task). ”return 1;” eg only works in the latter case.
We had been trying for weeks without result, both with trainer wheels and to run behind with an attached handle. Then one day we unmounted the pedals and lowered the seat... after just an afternoon we could reattach the pedals and he was now cycling on his own!
It depends on the userbase. I write medical imaging software intended to be used by MDs, and can’t just ask a random person at a coffeshop to try to establish a certain cancer diagnosis using our software. Finding candidates that have time for usability testing in that target group can be quite a challenge.
Dailyscandinavian seems to have mixed up the numbers a bit.
In Sweden parents get 480 in total together, of which 390 are at 80% (capped at 989 SEK = 138 USD / day), and 90 days are at a minimum level (180 SEK = 25 USD). Out of the 480 days, 90 are reserved to each parent (used to be 60 before 2016) and the non-pregnant parent (usually a father) gets extra 10 days at the birth.
It’s when you want to synchronize multiple atomics it gets complicated.
With a mutex you can lock for an entire ”transaction” where you fetch a unique index and write your value to the queue. With just atomics you can get a unique index into the queue concurrently with other threads, sure, but how do you mark it as ready to be unqueued once you are done writing your data?
Thats where lock free data structures come into play. They have solved this intricate synchronization between multiple atomics so you don’t have to.
