Why do we need fibers
...niteSeries.new.take(10) # => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
I don't know if this uses fibers under the hood, but it could. Fibers can be used to implement infinite lists and lazy evaluation of a series. For an example of some lazy methods defined with Enumerators, I have defined some here: htt...
Multiprocessing - Pipe vs Queue

Chaining multiple filter() in Django, is this a bug?
...__event=event) & Q(shiftregistrations__shifts=False)
What you can do now is to use an annotation count-filter.
In this case we count all shifts which belongs to a certain event.
qs: EventQuerySet = qs.annotate(
num_shifts=Count('shiftregistrations__shifts', filter=Q(shiftregistrations__e...

However, a more fully featured, more robust, tested script version is now available at the npm registry as CLI ttab, which also supports iTerm2:
If you have Node.js installed, simply run:
npm install -g ttab
(depending on how you installed Node.js, you may have to prepend sudo).

Structure padding and packing
...means that it can not deal with an usual byte arrays? Struct packing as I know mostly used in transmitting(i.e networking) a data, when you need to cast a byte array to a struct, and be sure that an array fit to a struct fields. If the spark can not do that, how those working at all?!

While you are usually free to design your own build process, nowadays most people will use a standardized approach such as Apache Maven. Among other things Maven defines defaults for which resources in the project structure map to what resources in the resulting artifact (the resulting...
