I'm not sure. I think a lack of metals makes a star less stable and burn out more quickly, but I could be wrong on that. There's some episodes of Astronomy Cast and Ask a Spaceman that I think would answer your question about

No. Size is the dominant factor. Lifespan and what stages of fusion it undergoes are dependent on its size. The more massive the star, the shorter its life span. Red dwarf stars can live for trillions of years, but massive stars may live le

Funny seeing this on HN. I worked at PolySat until 2010 (a year before that article was published), so I know most of those names. When I worked there, our avionics was embedded C on bare metal. We had several problems we were trying to sol

Assuming ZeroMQ batches messages like other message queue technologies, you're comparing apples to oranges. The article is about receiving 1M network packets per second.

Thanks for the list. I'll keep these in mind for my next GUI project. I've used Qt a few times for hobby projects, but was thinking about trying something else for my next GUI project.

It’s be helpful to have some concrete examples of where one might run into limits with the minimalist frameworks and why a larger framework is required to overcome those limits.

Heh. That's the argument that was made against using Rails' `try()` method at my last place of work. Made me laugh. Thanks. :)

> writing Rust like it is X year Are you reacting to the talk about "editions," e.g., Rust 2015 and Rust 2018? Those are actual concepts in Rust, similar to how C has C89, C99, and C11. I personally don't feel compelled

Thanks. Didn't know about the raw identifier syntax. That's kinda ugly, so I'd probably still go with copying it to all of my projects and giving it a new name if I were to update to Rust 2018.

That would make sense if science was a monoculture and could only be challenged from the outside, but scientists question each others' findings all the time. You can't have a scientific process without scrutiny.

The orbit didn't physically change. The author fixed his code and reran the analysis.

Eccentricity describes the shape of an orbit. 0 is perfectly circular. Between 0 and 1 is elliptical. 1 is parabolic. Above 1 is hyperbolic. So an eccentricity of 3.0 is hyperbolic, which means the object is of interstellar origin. (Picture
