Typically, threads are given functions to run. Worker threads are different, thoug, taking a *file*. This is where suspicion starts to come in, as sending execution to a separate file implies that the thread is a separate program, rather than a single program sharing state.

These are surprising improvements over traditional threading libraries, because it allows the thread to easily send and *receive* updates whenever it gets them instead of waiting until it's out of work to return everything it has collected. *However*, this still smells of running in a separate process, basically treating the thread as a peer to coordinate with across a network connection or a special kind of shared file called a "pipe" that I won't bother to discuss, here.

There's actually a lot more available, here, too. The threads can communicate through console I/O. A thread can set up additional communications channels, which can be passed to the parent for another thread, allowing two worker threads to communicate directly. Ports (endpoints to a communications channel) can be manipulated to prevent the thread from exiting, and so forth.
|

|

Like I said, though, we have our basic create-exit-join model *plus* communication back and forth, which is fairly useful for a lot of kinds of work. If they're not "really" threads, it doesn't matter much, as long as the code doesn't block and they basically at like threads.

As [discussed previously]({% post_url 2019-12-31-new-year %}), this is my weekly Twitter roundup. Note that tweets of articles generally include header images from the articles, which are not included here unless they *happen* to be available under a free license. Most are not. But I now add most of my commentary here, where I'm not restricted by the message length.
|
||||
|
||||
|
||||
|
||||
I also don't generally attach pictures to posts with quotations.
