Yahoo News Canada: One big step… for future missions: what did we learn from Artemis II? One big step… for future missions: what did we learn from Artemis II? Now, this causes the following warning: FutureWarning: Downcasting object dtype arrays on .fillna, .ffill, .bfill is deprecated and will change in a future version. Call result.infer_objects (copy=False) instead. I don't know what I should do instead now. I certainly don't see how infer_objects(copy=False) would help as the whole point here is indeed to force converting everything to a string ... London Evening Standard on MSN: One big step for future missions: what did we learn from Artemis II?

One big step for future missions: what did we learn from Artemis II? An asynchronous operation (created via std::async, std::packaged_task, or std::promise) can provide a std::future object to the creator of that asynchronous operation. The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std::future. The code above might look ugly, but all you have to understand is that the FutureBuilder widget takes two arguments: future and builder, future is just the future you want to use, while builder is a function that takes two parameters and returns a widget. FutureBuilder will run this function before and after the future completes. These actions will not block for the shared state to become ready, except that they may block if all following conditions are satisfied: The shared state was created by a call to std::async. The shared state is not yet ready. The current object was the last reference to the shared state. (since C++14) C++ includes built-in support for threads, atomic operations, mutual exclusion, condition variables, and futures. The class template std::packaged_task wraps any Callable target (function, lambda expression, bind expression, or another function object) so that it can be invoked asynchronously. Its return value or exception thrown is stored in a shared state which can be accessed through std::future objects. If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. This function may block for longer than timeout_duration due to scheduling or resource contention delays. The standard recommends that a steady clock is used to measure the duration. wait_until waits for a result to become available. It blocks until specified timeout_time has been reached or the result becomes available, whichever comes first. The return value indicates why wait_until returned. If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting. The behavior is undefined if valid () is false before ... The scoped enumeration std::future_errc defines the error codes reported by std::future and related classes in std::future_error exception objects. Only four error codes are required, although the implementation may define additional error codes. In summary: std::future is an object used in multithreaded programming to receive data or an exception from a different thread; it is one end of a single-use, one-way communication channel between two threads, std::promise object being the other end.
