No, the most annoying thing in IT is the person you're responding to, who doesn't understand how TLS for email works in the first place, but pretends to do so, and participates in discussions as if he knows the subject matter at hand.

The error being that there is no encryption applied by the person who writes the email, but opportunistically by the email servers if both sending and receiving email servers supports TLS. This is done transparantly to the end users (ie the people who write the email).

Oh come on.

It's always hilarious when people pretending to be techies on slashdot discuss technical matters without understanding the matter at hand.

There is no encryption being removed here. What is being removed is the negotiation of encryption. There's a huge difference.

What happens here is that modern MTAs that are configured to use TLS will issue a STARTTLS command to the receiving email server. If the receiving email server is configured to accept TLS connection, it will respond in kind. If it rejects the command, the conversation continues unencrypted.

Most email servers are still not configured to use TLS.

What happens in this case is removal of ngeotiation of opportunistic encryption. It's of course very very wrong to do this, but it does not remove existing encryption - it prevents it from happening in the first place. It makes the parties believe that neither side supports it.

If that was a serious question, and not trolling:

The in-addr.arpa DNS zone is used for reverse DNS.

Basically, you forward-map hostnames to IP addresses. At the same time, you can reverse-map IP-addresses to hostnames.

The forward mapping is done via 'A' records.
The reverse mapping is done via 'PTR' records, and it's done in the in-addr.arpa hiearchy.

Given your description, you're the sole sysadmin. This means you're the person who should take these decision - nobody else. If the company disagrees with this, then either you've done a poor job previously, or they don't trust you to do your job for some strange reason.

Now, if it's you that have fscked up on previous occasions, then it's understandable that they want the red tape.

If you haven't, then it's time to put down the foot and say "Nope, that's my job". If they disagree with that - linkedin should be a relatively short distance away, and after you find yourself a new job - simply hand in your resignation pointing out that you have no interest in having babysitters.

What repopulates the area? Easy.

Taxes & import duty are very tiny. You've got some of the most beautiful nature you can imagine. There's lots of researchers connected with universities etc. - making for lots of interesting people to talk with.

A lot of the turnover is actually students wrapping up their studies.

This is quite an interesting idea. DYI drones are getting more and more common - and there are plenty of people with electronics background who can make the control interface.

Make the commands sent to the drone be sent encrypted/signed - allowing automatic handoffs between controlling terminals.

It would be pretty easy to make drones do the 'chore' of crossing international borders for you. Just put out a couple of 'base stations' that are quiet unless the drone is coming by .. and which directs the drone when it is close.

I'm wondering how well prepared border control / custom agents are for taking down fast moving drones that sweep in pretty low.

I'm sorry, but first off - Magnus Carlsen has been an extremely well known chess player since 2004. Justin Bieber was discovered when? 2008?

Secondly, while Bieber is famous for being famous.. Carlsen is famous for using his brain and becoming the world champion of chess. He built his career around his brain. Yes, some fashion agency also discovered his good looks and started sponsoring him and using him as a model - but that's not his main work. It's a hobby thing on the side. Good for him.

For those slightly interested in chess, but not interested enough to normally follow ratings and such - take a look at: http://2700chess.com/ for the up to date live ratings.

Aronian is doing a massive jump these days due to Tata Steel. I'm guessing the next WCC match will be between Carlsen and Aronian. They're typically rather evenly matched.

Uhm. Easy to fake? So, how will they fake out the huge amount of telescopes that will be pointed at the moon when they approach? How do they fake the large amount of listening posts that will listen for the chinese signals from the moon?

Not to mention, flybys by other nations, later, will look for the equipment. It would be kind of embarrassing when nobody can find it. ;)

The computer would not need a history of games of the opponents.

Computer chess has moved so far ahead of human players that Carlsen would have been utterly destroyed. These days, spectators watch the game with chess computers on the side, since the chess computers can tell properly which player is ahead, while spectators wouldn't be able to tell properly.

Chess engines such as Houdini, Stockfish and a variety of others have ratings well above 3100. Carlsen has a rating of 2872. He would be crushed.

I hear people claiming that about the command line, but this has never rang true to me. We probably use computers in very different ways.

I have two 'defaults'. Either I'm using various terminal based programs, or I use a webbrowser.

email? Check. Using mutt.
IRC? Check. Using irssi.
Web? Chrome.

I need to edit something / write something down? I've never come across anything better than vim (emacs would've been just as useful if it was my editor of choice). I'll write my stuff there, and store it in text files. Calculations? bc is usually all I need. What if I need to manipulate some data files of some random human readable format? I usually just grab for perl.

Almost everything I do, is done either done in the shell, or is done in the webbrowser. Now, my use case is obviously different than yours.

I've been using computers since '86. Was a huge fan of DOS back in the day. Didn't like Windows 95 much, but eventually installed it in '98. That didn't last too long - around April or March '09 I figured I should try out Linux. First I went with slack, which didn't work out for me. I seem to remember that I first went for Debian, and then later on for SuSE for some years. Then it was a series of SuSE->Mandrake->SuSE->Ubuntu.

I had to fiddle a bit with Win2000 as a window desktop, and then later fiddle a bit with I think it was Win2000 or was it 2003(?) on a few servers. The main bulk of the servers were Linux and Solaris.

I very seldomly had to help out some XP users. I've barely touched Vista, and I don't think I've seen more than one computer w/Win7 ever. Anything newer than that and I haven't seen it at all.

Now; why won't I touch Windows? Quite simple - I have no clue how to do stuff with them. Family has been converted to Linux (and some Mac) years ago. I wouldn't know a thing about how to get stuff done. I've heard rumors that powershell is kind of cool - but I'm familiar with bash that I guess my only option for windows would've been cygwin - but that feels kind of bastardized instead of just having a desktop I immediately feel familiar with.

I'm pretty sure windows is quite cool for those who knows how to use it, but it ain't me.

Put your best foot forward. Or just call in and say you're sick.
