The question is whether a tiny cubesat can emit enough plasma to be even *detectable* with radar or other ground based communications (like ham radio). There is very little mass available. I suppose this is a science experiment to characterize the dispersal and recombination of plasma clouds in LEO. That might be useful for understanding natural processes -- or as a prototype for some *serious* propagation enhancement project in the future.
IIRC, there have been experiments like this in the past with sub-orbital rockets that emitted ion clouds. They make nice visual displays.
Ham operators use ion trails from meteorites for communications. They last for a few seconds at most.
On the face of it, it seems the US Government is recognizing privacy rights of EU citizens -- that the US does not give its own citizens. What does the US get out of this? More profits for MS, Google, et al.? I would support it if the US was willing to step up to European standards of privacy for everybody.
Can't find any clue as to what frequency is being used for the charger. The prospect of 50 kW of power in your garage or wherever is worrying, despite being "well shielded". Even if it's a lower frequency (in the kHz range), there will be harmonics all over the spectrum, putting radio amateurs and anyone else using sensitive radio gear in a bind.
Negative rates are nothing new. Banks have been doing this, but instead of "interest" they call it "fees". For any smallish balance, you've been getting a negative rate for a long time now.
This is reasonable in a way. I am happy (more or less) to pay a small fee so that I don't have to carry my savings around in a wheel barrow. The bank provides safety and convenience. The value of this service is proportional to the amount, so it's fair to charge a negative interest rate -- as long as it's small.
This is the single worst thing Microsoft has ever done in my book. Basically, they are trying to gain control over every Windows PC out there. And it's not going to be optional if they have their way. Forcing you to download 5 GB of undesired files is just the beginning. Once you're locked in to Win10, all your data is theirs. They are transforming the desktop PC into a locked-down glorified cell phone.
There are two things here. Do you identify yourself (publicly or personally) as "Christian" -- or "Anonymous"? That's entirely up to you. The other is would other people identify you as "whatever"? If you do religious things and act out of religious feeling (as the world sees it), then the world might call you "Christian". (By their fruits you shall know them.) If you're an Anonymous hacker and you participate in their stuff and people know that you do it, then they'll say you're part of Anonymous. Not a big deal IMO.
Hellschreiber *is* a type of fax service -- stripped down for use with simple equipment and a noisy communication channel. It has been around for a very long time. Why are we suddenly rediscovering it?
"Cosmologists Find..." makes a snappy headline, but TFA is right - the discoverers were astronomers. Those galaxies are far away, but probably not at _cosmological_ distances, i.e. comparable to the scale of the universe. The scale of astronomy is mostly << scale of cosmology.
Or perhaps TECO, the world's most perfect text editor? A TECO command string is famously like random keystrokes. I suppose comments were possible, but I don't remember using any.
The abstract doesn't say how bad it is to be hit by a GRB beam. GRBs don't last for more than a couple of minutes. It seems that would fry the side of the planet facing the GRB, but the other side would be shielded from much of the radiation. So you zap half the lifeforms and maybe you boil some ocean. No doubt it's unpleasant on the dark side, but is it lethal?
There are at least 2 issues with cloud mail like gmail -- having GBs of mail archive sitting there (the static problem) and you have email coming & going over SMTP (dynamic). Got to deal with both. Unfortunately, you probably do need a first class (authenticated) SMTP relay for reliable outgoing mail. Tanstaafl!
I just replaced my Google Mail account with a Raspberry Pi running Postfix and Dovecot. It does the job, if you don't get more than a few messages per minute. My motivation is to reduce my Internet Data Footprint -- the amount of stuff that is available to Google, NSA, et al to paw through. It uses trivial power, so there's no issue running 24/7. (If you're thinking about this, I'd recommend the BeagleBone Black - a lot faster for $10 more.)
The worst downside (besides having to set up and manage the thing) is spam control. Gmail is excellent at this, and Postfix/Amavis/Spamassassin only catches a fraction of the incoming bad stuff. There are cloud services for spam filtering, but they seem expensive for a single user.
This is basically Dropbox parroting Google's Chromebook. I use a Chromebook at times, and it's remarkably good for 90% of what I do. Doesn't seem to run automake, however.

TECO will solve all your problems.
(or "best regards")
"73" is well known in the telegrapher community as the code for "Best Wishes". It is commonly used in ham radio to this day.

Just let TMO explain that they're optimizing shareholder value. I think that's the expression.

And what company is pure enough for you?
Anybody who gives you free social networking is evil, and anybody who charges money will fail.

Perhaps you are thinking of APL?

Clearly, you can NAT an entire nation! IT JUST WORKS!
(Of course, the fact that one of the most reclusive and oppressive nations in the world is using this isn't a shining endorsement, but still....)
Sure, but your big NK router only has 64K ports per external IP address. It will probably croak well before it has 64K NAT sessions going, though.
Run BOINC. Discover pulsars, gravity waves, prime numbers, cure cancer. Isn't that enough?
If you haven't used TECO, you might not be a real programmer. (The languge that is indistinguishable from line noise.)
You're surprised that Mosaic doesn't run well on current hardware?
Analytics = !Synthetics Tearing stuff apart instead of putting stuff together.
But those are some expensive radio covers.
