In Dutch, this has become the thing people do now as well. Being a Germanic sister language of German, Dutch also does/should not use the apostrophe in this sense, but people do it anyway. Then again, a language is a living thing, and in the end, it is what people speak and write. I can live with this.

Stolen directly from Reddit, but very true.

Yes, and no. Yes, if you work off the model where there is a universal "now", and light just happens to travel at some high speed. In that model, the explosion happened, and we are now just waiting for the light to finally arrive. However, the problem with that model is that there is no universal "now".

So no: The speed of light is not related to light. Light travels at that speed, but there is nothing about the properties of light that somehow determines that speed; other things, such as gravitational interactions, travel at that speed as well. That speed is not just some arbitrary speed limit, but rather the speed of causality, full stop. There is nothing at point A that can even influence point B in less time. This is what determines our past light cone, or rather, our past causality cone.

And to be clear: this star's bright light-up is not in our past light cone, and so, for us, it did not yet happen.

The fact that we nowadays have these launches and first-stage landings as a matter of course, with little mention outside of technically-minded news sources, is in fact a great achievement. This is exactly what space travel should become.

There isn't really any proof that Waymo vehicles are driverless, only that the driver isn't in the vehicle. If you compare a dozen dubiously driverless vehicles to a million collecting data every moment and already doing a pretty good job at autonomy, which do you think will succeed?

The fact that the driver is not in the vehicle does not mean that there is no driver.

I believe that this was figured out in the amateur observer community before NASA confirmed it. I saw it go by in my twitter feed. Not sure I can find it now...

Linear Energy Transfer

It's not radioactive. When high-energy particles strike it, they break apart into lower-energy particles that are more harmful. So, you need enough shielding to catch the particles that break apart in the top layer of your shielding.

While radiation mostly results in transient errors, it can also cause latch-ups that blow a gate off of the die. For rad-hard equipment in space this is mitigated by silicon-on-insulator fabrication, so that you can't have a latch-up between the substrate and a silicon feature.

We could have REAL ZOMBIES! YEAH!

I hear you. Going to be an interesting future, if we live.

Oops. To continue: I'm just not seeing that it is so hard to access. But then, I use a Linux desktop, which has always come with a proper PDF renderer, there has never been a need to download "Acrobat".

Web pages use SVG to render vector graphics. It uses the exact same imaging model as PDF and is implemented in all modern browsers. The web in general has taken a lot of lessons from Adobe because Warnock and Geshke, in the PostScript Red Book, got so much right about how to build an image model that many GUI developers are still learning today. If you start with a PDF, it should be possible to machine-translate it to SVG and present it as a web page.

PDF exists because it is trivial to generate it from the document renderer meant for printing. Although I have once in a while run into an improperly scaled PDF meant to be printed 8-up, I'm just not

Lithium battery fires are in the news because they are new. There are many more gasoline fires every day.
