A TUI FFMPEG builder would be delicious. Just a terminal powered graphical interface that lets me manipulate options, and feedback validation, would make it so much easier to work with complex graphs.

Many thanks! > if you telemetry isn't already packetized, you'll need to do that yourself. Converting your drone's telemetry into something that ffmpeg likes is generally non-trivial. Yes, this is exactly the non-trivial s

The data has temporal component, yes. But how would I packetize it in the first place? I have the high-level concept that I need to take each of my data chunks and put them into some kind of timestamped container/page/atom and fee

The dry-python lambda soup is awful, I totally agree there. That's just there mostly for demonstration purposes though. Generally you'd actually use the flow construct (monads) to compose methods. But `obj and obj.method()` really

My understanding is that Borgs can be subclassed, you can modify the behavior, use descriptors (setters/getters), etc. You also avoid the `global` keyword. It's really not the most compelling reason. I recently found a cleaner way

Question for the peanut gallery, because it's vaguely topical and I've spent hours researching problem to no avail. How can I mux arbitrary data streams into a container? Let's say I have a drone and I want to stream audio, v

Dependency injection and lazy_property are excellent, I use those all the time. I've used visitor on occasion. The rest? Mostly meh, some are straight up bad.

It's basically a global / hoist with a more ergonomic way of accessing the state. Instead of a get_global_state() style function, you just have the Borg constructor. Personally I'm a fan of dependency injection whenever possi

Nullable (Optional[Foo] / Union[Foo, None]) and Maybe[Foo] are similar but not quite the same thing. The difference is quite subtle. Optional[Foo] is same as Foo | None, meaning you can operate on foo with Foo's methods, except th

I was in the same spot when I met this brilliant hardware hacker at this hackerspace who had no formal EE degree but could design circuits in his sleep. "How do you do it?" "I read data sheets and a lot of wikipedia". I

We really goofed as a society on that one. "But humans have ten fingers!" Well, we actually have 8 3-segment fingers and 2 thumbs, meaning you can count a dozen on one hand, and a gross on two, using thumbs as a cursor. You can al

If you use ULIDs for IDs (sortable by time, millisecond resolution) and a tombstone field (nullable deleted_at is a good one) then you have a very stable collection that guarantees no new objects will be inserted/deleted before the wri

The article mentions a virtual optical fence that cuts the beam if anything impinges, so no roast pigeon with this system. Anything which the beam could couple to, haze, smog, etc, would definitely reduce efficiency for sure.

Despite its warts, Python's type system is at least comparable to Go, and better in several areas. The type inference works really well much of the time without any assistance, you can use tools like pyre to generate types for untyped

You mean statically typed? Python is already strongly typed. Try running it through mypy with all the strict options. If you can get it to 100% pass and don't try to "cheat" the system too much with dynamic casts, I think you

How does that solve anything? Any hardware is gonna try to route packets to the "original" x.x.x.x and completely ignore this option field.

It's all about managing entropy. Less surprising means you can use fewer letters. More surprising means more letters. That shouldn't be too controversial. The part where it gets tricky is when a concept is widely used, but is a co

Underground construction is really hard to do correctly. Partial earth bermed foundations as you mentioned are a good compromise, especially if the earth is built up. But even then, drainage and soil pressure are big engineering concerns. A

That's more or less what PEP 659 tries to achieve, albeit without the flag. Given that nearly everything in Python is an Object and can be modified/patched at any time, this dynamic adaptation is probably as best as one can get,

A big part is that Python uses reference counting GC. Java, Go, C# all use tracing GC. Py_INCREF and Py_DECREF are responsible for inc/decreasing the reference count, and are not atomic. The GIL ensures refcount safety by allowing only

It needed to be done; there were several choices in python 1/2 holding the language back, that all but necessitated breaking changes. Mostly with string/bytes/unicode handling. And the non-breaking route would have been a lon

I think python is finding the loosey-goosey dynamic everything makes for bad application scalability, both for maintainability but also performance. Python with types, on the other hand, is pretty great for catching bugs before runtime.
