What is the limiting factor? Buildup of CO2?

People need a certain amount of oxygen for their metabolism, you need to carry that much. CO2 effects the blood pH: too little and the body is too alkaline, too much and it's too acidic. So, you need to maintain a precise amount of CO2 and remove the rest. The scrubbers in the space shuttle were able to regenerate the CO2-absorbent material after use, so there was use of power but material wasn't consumed.

Beyond this, you need to control temperature and humidity. The other requirements than atmosphere for crew survival are that you water, feed and shelter the crew, maintain orientation, and maintain a G-force envelope that doesn't injure the crew.

Submission + - September 19th SpaceX Launch will be visible across California, Nevada. (reddit.com)

Bruce Perens writes: The nighttime launch of a SpaceX Falcon 9 containing Iridium satellites at 9:49 PM PST Monday September 19th from Vandenberg AFB SLC-4 is likely to be visible across California and in some Nevada locations. Although Vandenberg has a landing pad for the Falcon under construction, this will probably be a drone-ship landing and some California observers might see two of the landing burns.

Comment Crashplan between friends (Score 1) 356

You probably have a friend with a similar question. The solution is that you buy a backup disk the size you need, they buy a backup disk the size they need, you both install it at the others place and then you run Crashplan between yourselves. That gives you off site version controlled backups.

Done.

Precisely. It's like the idiot light on your car for gas/overheating/whatever. If you failed to note the problem, it might warn you. Find a lightweight program and suck it up. I ran without AV from the late 80s to about 2011, and then I gave in based on the more subtle threats that were becoming common. Just not running scripts and untrusted attachments wasn't feeling entirely safe in an age of hidden filesystems that could get past air gaps.

For the record, i'd never gotten anything I knew about and no AV was ever able to find malware on my personal systems. No guarantees, but it was a pretty good record.

I've been injecting insulin and other drugs for 16 years now. No fuckups. No reactions. Nothing, and i'm no one special in this regard. It sounds like epinephrine is less stable than insulin in storage, but I could work with that - I used to carry my drugs in a sealed metal thermos on travel. Deployed to Iraq and back that way in 07-08.

Tee hee! Back in the day, one of the points I made to the old farts was that I had passed the 20 WPM exam and had my K6BP call to show for it, but refused to use the code on the air until the requirement was gone. Nobody spat at me or punched me out, the worst that ever happened was a poor behaving slim using my call and a postcard from the ARRL observer who thouht it was me.

WSPR tells you when communication paths are open between two points at a specific frequency and S/N ratio. This is useful but does not span the extent of research that HAARP is directed to. One of the most interesting things about HAARP is that it can incite the formation of radio-reflective regions in the ionosphere. That takes a lot of power.
