Nobody's landed a MOXIE on Mars before, not one broken or working. Until that happens you can't definitively say "yes you can produce rocket fuel to go back home to Earth with". Once you can say this, the logistics for putting a human on Mars and returning him safely become a realistic goal. Right now it's just a theory.

to maintain your correctness. You are wrong

 
I'm glad I could make your day by making a broad statement that you could nit-pick to feel better about yourself. Congratulations on your tiny win! You deserve it.

"Normal use" for my grandparents is "Off"

Yes, this is idea. The google play store is completely useless for finding top notch apps. As with the PC market, there's usually 2-3 applications that have all the features and aren't buggy and don't have a terrible user interface, and then 1-2 open source options that are very similar, and then 10,000 one-off single feature applets which are mostly useless and ancient.
 
I don't even use the google play store search function. I just google for lists of top versions of the type of app I need (with this year's year in the search results), then go download/buy that one and hope it stays updated.
 
I used to wonder why people use brand names when product names are so important. This is why. Complete chaos. In 10-15 years there will probably be an umbrella of 20-30 companies that offer suites of good programs that all work together well. Right now I'm going to avoid a new program by a new developer unless it does proper magic like Word Lens (which is now owned by Google), and just stick with curated lists on %RandomAndroidApprRviewSite%.

Given your pedantic argument, I stand by my statement.

So you've come up with the ultimate heat sink, but now you have to run it in a positive pressure ventilation clean room.
 
Might as well just stick the PC in the closet and run an HDMI over Ethernet to your desk and use wireless mouse/keyboard. Now that we're not forced to use a maximum of 9' VGA cable, and nobody uses physical media anymore, there's zero reason not to stick the PC somewhere else and run an extra CAT-6 drop for the video (HDMI over Ethernet needs 2x1gbps)

And in the 20th century Spain was mostly a ghetto and the rest of the Spanish speaking countries, banana republics were mainly dealing with internal conflict (or US intervention *cough* Guatemala *cough*; all of South America has been peaceful since the Bolivar republic split over 100 years ago; China hasn't had a military victory of note in the last 120 years, which is why I explicitly said 20th century. Thanks for the irrelevant 400-year history lesson, though.

And yet strangely the two largest language groups are Mandarin and Spanish, the two least successful millitaries of the 20th century.

NASA is mainly concerned about micro debris from the comet/coma shotgunning the solar panels/instruments at 60,000mph

It's really hard to do this kind of landing burn (nicknamed 'suicide burn' as you run out of fuel as the landing feet touch the ground at 0 velocity, and miscalculation and splat or a nice bounce (elon called it the hover slam)) with a solid rocket booster, which we keep buying/making to prop up the ICBM industry with civilian dollars. The shuttle ended up with SRBs instead of L(iquid)RBs purely due to political reasons.
 
Actually, for the Saturn V, blueprint drawings do exist made by NASA of a cockpit on the side of the main booster tank with glider wings, to take it the 300 miles back to a safe landing site. Obviously that complication got scrapped in the mad rush to get to the moon in a decade.

The wiki page they link to has a photo of a converter that converts solar DC to electric grid AC. I'm not sure if they're looking to do residential solar with the inverter on the back side of the panel group or use this in a datacenter...

I've yet to see the "killer app" for the Pebble smartwatch. Neither could they, which is probably why they open-sourced the SDK. If they had a killer app they would have been purchased (or emulated) by Apple/Microsoft/Google et all already.

Distributed drone delivery and refueling? Bit torrent for packages! Genius! Cut the US Postal service out of the snail mail business completely using technology in e-space and meat-space.

Have you looked at how much robotics parts cost? A cheap servo is $12, an acceptable servo costs $45, and good servos you might use with surgical precision start at $95. High torque high precision motors a human sized model start in the $450 range and go up from there.
 
Six range of motion arms (let alone three digits per finger) means 12 servos for just the arms. It's no wonder people are looking at pneumatics, hydraulics etc for high torque high precision "digitla muscles". Robotics is expensive. And when you wire a servo wrong at 4 in the morning because you've been working too long you end up replacing these things at a fast rate (Ask me how I know). Just getting in to a 5 degree of motion laser cut wood arm, starting the hobby from scratch, cost me about $600. And that's with the $12-20 level servos.

Social media works great for things I will talk my friends about movies, politics, and occasionally global sports like the world cup or Olympics. Since I don't watch TV I couldn't tell you what's playing right now, especially since most movies are reboots or sequels which really blend together unless you've seen the trailers a few times. I did end up buying a ticket to the Lego movie due to an ad on Facebook. After almost all of my friends had been talking about it for weeks. Ads for dishwashing soap, soda, pizza etc don't even register for me mentally online.
