On the right of the image is a sheer cliff face marked with vertical striations; talus lies at its base. The left of the image is in almost total darkness, and the background is deep space.

This is a cliff on comet 67P/Churyumov–Gerasimenko.

It's about 1 km tall.

If you jumped from the top, it would take you 47 minutes to reach the bottom, and you'd probably be OK.

I like coming across vehicles like this as they don’t like right when they do there job but clearly they are built for purpose but just not something you see often. #reference

I guess 0 technically has two syllables, but I usually read it as "oh" in this context.

This is how I do it too, and with 7 being the only two syllable digit there are only 8 distinct "beat" patterns across all 3 number combos, and they each have a nice little rhythm to them, makes it easy

Road Rash - pure nostalgia from playing it with my Dad (and working together to hack the checksum based save codes)

A rough, rubbly looking terrain that looks like that weird lint crap that builds up in crawlspaces.

Six tile image showing the progress of the lunar eclipse. Top two images are partial but last four are closer to full eclipse and so are red.

Six tile image showing the progress of the lunar eclipse. Top two images are partial but last four are closer to full eclipse and so are red.

Here come my #LunarEclipse pics from earlier tonight. Imaged with the DSLR attached to the telescope (as my lens).

These six are my best ones from the event.

The clouds were ultra-annoying but I managed a few snaps when there were empty patches.

The last total lunar eclipse until 2028!

The full moon, partially eclipsed and behind some thin clouds

These first two show Earth’s curvature, as the Moon moves into Earth’s shadow (sorry, flatearthers).

I really like the first one, as the Moon sits just above the dimly lit silver ridge of a cloud. The shadow makes it look 3D and SciFi-like.

The second is behind some thinner clouds.

This is a good analogy. He moves any piece he wants in any way, fills in white squares black with a sharpie, etc. His sycophants clap loudly at his genius and the rest of us are standing around hemming and hawing about how that's against the rules

Grew up in Chicago, live in Indiana now, it's rough. I can get away with an ironic "y'all" every once in a while, but if I really need to address a group it's something awkward like "what do we all think about [pizza|mexican|a movie]?"

Agreed, unless you can’t choose the beer and get stuck with an 8% IPA or something. Interesting twist would be 1) you can’t tell anyone about the $50M, and 2) it has to start on a Tuesday

There's a lot of "fine print taketh away" in that last paragraph. I've had experiences like his first example, and I've had really awful experiences with the same models trying to do things like re-factor ugly legacy code. I think the occasional big wins tend to cloud our judgement.
