The Most Detailed Images of Uranus' Atmosphere Ever 105

New submitter monkeyhybrid writes "The Planetary Society's Emily Lakdawalla reports on the most detailed images of Uranus ever taken. The infrared sensitivity of the ground based Keck II telescope's NIRC2 instrument enabled astronomers to see below the high level methane based atmosphere that has hampered previous observations, and with unprecedented clarity. If you ever thought Uranus was a dull blue looking sphere then look again; you could easily mistake these images for being of Jupiter!"

System Admins Should Know How To Code 298

snydeq writes "You don't need to be a programmer, but you'll solve harder problems faster if you can write your own code, writes Paul Venezia. 'The fact is, while we may know several programming languages to varying degrees, most IT ninjas aren't developers, per se. I've put in weeks and months of work on various large coding projects, but that's certainly not how I spend most of my time. Frankly, I don't think I could just write code day in and day out, but when I need to develop a tool to deal with a random problem, I dive right in. ... It's not a vocation, and it's not a clear focus of the job, but it's a substantial weapon when tackling many problems. I'm fairly certain that if all I did was write Perl, I'd go insane.'"

Good answer. To be fair to the parent post, the certificate authorities *do* have some work to do in cleaning their own houses. Stolen or compromised certificates do exist, and while we can revoke the ones we know about, there's the ones we don't know about, and there's the clients that don't handle revocation properly. It's not clear that the CA houses are doing their jobs well enough.

That's not wrong, but it still doesn't explain to me why I, as a user, should trust both application A and site B that have agreed to trust each other with a self-signed certificate. The reason was have the CA model is to introduce a trusted third-party* that can verify for us that everything is on the up-and-up. The user should not be in the position of having to trust unknown parties.

*Yes I know the CA companies have problems. Maybe the model is so broken by nature that it doesn't matter, but it's still true that the self-signed model bypasses it.

it does not delegate trust to some 3rd party that might screw up and cause things to have be changed, or risk compromise

Instead, the company that issues the self-signed certificate is to be trusted not to screw up? "Just take our certificate, it's fine, trust us".

If Alice and Bob trust each other, this is OK, but what if Bob is bumbling idiot? What about when Alice and Bob, who trust each other, tell Mallory to trust them to trust each other, and Carol mistakenly trusts Mallory?
