First, thanks for your very interesting posts. Do you mean visibility at ground level or at the altitude where the pressure is 1atm ? If the former, then why did the Russian probes only show pictures with about one meter of visibility ?
Personally I really liked the idea put forward at the end of K.S.R.'s Blue Mars: put a gigantic thin (monomolecular) film at L1 between Venus and the sun to lower the solar input and let Venus atmosphere condense to the ground.
It gets worse: we couldn't pee in the toilets either ! This was insanely hard not to do and took the training of a yogi master. The reason is that the toilets were actually shit burners and liquids would mess them up, if not straight short-circuit them !
Yeah, I don't really understand this rule. It's not like you pee alcohol after drinking it, it's transformed by the body (acetaldehyde, then acetyl).
Also I tested a water recycler for a year while in Antarctica, which was intended for space use (it was an ESA model, probably different from the NASA one), and there was no limit to the amount of alcohol we could drink (fortunately!!!), yet the only issue was with some shampoo and urine: we had to use the officially sanctioned shampoo and we were forbidden to pee in the shower ! Well, now that I think of it, it could have been due to the high alcohol content ! No, seriously, IIRC it was the urea which would damage the reverse osmosis filters.
But then if the footage 'disappears', so does the checksum. While with an online realtime blockchain you at least know that the footage did exist at one time, even if a truck rolled over the camera...
Ideous ? Why ? Most (all?) countries have an ID card system. It's necessary for interactions between you and the state and I don't see what the big deal is. I guess replublicrats find it easier to cheat on elections without ID cards.
Yup: Banqiao Dam, 1975: 170000 dead, 10 millions displaced, an ungodly amount of land stripped to the bedrock and uninhabitable forever... Fukushima is a joke compared to it.
Checksum every minute (?) of footage and feed the checksums in real-time (or later offline if no connection at the time) to a public blockchain used only for that purpose. Then archive the footage.
Now, slightly different case. Hear me out:
- You work for a FOREIGN gov agency on critical material (say nuclear for instance)
- You are invited to the US for a collaboration, so you take work (encrypted) laptop with you.
- You are not allowed by your gov to give access to anyone
- At US border, TSA asks for access.
What do you do ? What CAN you do ?
Color CCDs have several disadvantages over monochrome ones for science applications: lower sensitivity, bleeding, aliasing, complexity... So normally for color pictures in space, they simply use filters of various frequencies: R, G, B for color pics, but also IR, UV and various peak frequencies of interesting chemicals (very important for science). This way it's not just a camera, but a full on science measurement. Every space camera is used like that. But why wasn't it used here ? Simply because the relative motion was too fast: they already had to use a short exposure time in order not to get a blurry shot, but changing filters take time and the pics wouldn't match in later post-processing. This method only works for subjects that don't move (or if you don't move yourself).
The more energy they pack, the more damage they are likely to cause when something goes south. Shouldn't there be some kind of national certification / testing program before they are allowed to be put on the market ? Discuss...
OK, I started reading the comments hoping to be enlightened about what "Concepts" are (Gee, another common word reused to mean something else, it's going to be great searching for that on Google), but you are the only one who even mentioned it. Everybody else is too busy fighting about the bloating of C++.
So I'll ask: what are Concepts ?!? And please talk to me like I'm a stupid C programmer...
...we need the ability to disable permissions right upon installation of the app. When android says the app requires wifi password, camera, SD card access, your firstborn, address book access and more, there should be a box next to the permission to disable right then. I know there are apps that allow you to do that, but you need to remember to run them afterwards, you need root, and you need to redo it in case of upgrade.
What's the point of having a piece of plastic gathering dust in your house ? It's not like I want to watch a movie more than once. Except in exceptional case I can count on 2 hands.
No one is actively taking your gasoline driven car away.
Well, if you follow what is currently going on in Europe, in many cities they actually are: you need to purchase special stickers for you car depending on it's type (old diesel, recent diesel, hybrid, full electric, etc...), and at some times the more polluting models are simply banned from entering the city. In some cities it means most of the time making those cars useless if you already have them.
This is neither good nor bad, but it's unquestionably different.
I beg to differ: it IS bad. Because when you read a+b, you have NO idea what may be happening. And this applies to ALL the operators. And the effect of the overloading can be completely different for various types. If participating in the underhanded C contest is not too hard, there's no need for an underhanded C++ contest because it'd be beating a dead horse.
Exact same thing here. Soon after purchase I noticed that the phone was slow: 15 to 45s to switch apps ! After a year it was unusable, burning hot, kept rebooting for no reason, couldn't read the SD card anymore, etc. Fried mobo.
The ribbon was the ONE reason I gave up on Office for good and took on OpenOffice and then LibreOffice. A set of menus and buttons without order that changes depending on what you are currently doing, so it's impossible to have a memory of it, yeah, what a great user interface advancement, right ! And it takes up a lot of real estate too, instead of being nicely tucked away in hierarchical menus with quick alt-keys...
Their dates seem off. I thought that monogamy in humans had emerged with agriculture: once you own a plot of land and invested lots of work into it, you pretty much want to limit access to it (and its production), so that means only to your kids, and to be sure the kids are yours you pretty much have to be monogamous. See all the still existing tribes of hunter gatherers that practice polygamy.
The encryption does not necessarily need to happen on the fly. You can save the images and videos as usual, and then pipe it for the camera to process slowly, even when it's been turned off. Making it use little power is more important than speed IMHO. Although I see no reason why encryption cannot be added to the ASIC.
The above mentioned law, voted in France in... 1978 (!) offers a good start: government entities are allowed to collect user/citizen data and make databases out of it. But they are expressly NOT allowed to share it with others (even other branches of the govt). This should be expanded to the private sector. And it also should actually be _applied_ because in later years in France they've been stepping all over this law.
Yeah, like you are going to start arguing prices with an hospital. Right. The ONLY ones who can do that are centralized healthcare systems like in Europe where they argue prices, enforce them and sometimes (rarely) fine establishments who won't play along.

visibility is a couple kilometers

There is no clear, universally agreed definition of what a continent is.
I've been to all 7 continents. And even if they add an 8th one in NZ, I don't care as I've been there too !

So it's artificial intelligence vs natural stupidity...?
I knew it'd come to that someday.

Thank god Altavista is still around !
