I can't. I bought with some high expectations, unfortunately I knew almost everything in it from a couple of years of using ssh to my several VPSs. I was quite disappointed at the level of detail it had -- StackExchange level, I thought.
You're right that it doesn't go into detail but it's short and provides high-level overview of the most important features. It's much easier to learn the basic of something from a book and then find the details in the manual than working with the manual only.
But if someone expects to gain deep, expert level knowledge of how OpenSSH works then he'll be disappointed. What expert-level books can you recomment?
Unfortunately, I can't recommend anything, but I'm not a wide reader on the topic so my knowledge is limited.
Perhaps I was a bit hard on that book, my expectations were that it would be a deep, expert type of book. If that's not what you are looking for, it is perfectly fine. Actually, now that I think about it, the epub version is good to keep on your mobile phone as a handy, easily-accessible reference for use in the coffee shop, so I guess it does get a credit from me.
A friend of mine was a trader of some long term with a particular bank and, because of his length of service with the bank, had to receive a few month's notice of termination.
They terminated him and made him come in to work to sit in a featureless room with only a table and chair -- no computer, nothing. He'd rather stay at home and garden or whatever, even it meant finishing up early, but they wouldn't let him. He always said that he must have seriously pissed someone off in HR.
Despite the other commentators' views, I completely agree. My Panasonic's YouTube app cannot ffwd or rewind. WTF! For a video streaming app! Unbelievable.
What I do is fire up the XBox. It's a brain-dead app there too+, but at least I can rewind a few seconds if I missed a word or two.
+ Titles truncated too much; no comments viewer; unresponsive UI.
But neither can Mars. Most of its early atmosphere was blown away and that will continue. There's nothing we can do about the lack of gravity.
The problem with Mars is that it is cold, terminally. The nuclear furnaces have gone out. I haven't seen a proposal from the terraformers that counteracts that. You might be able to counteract it with CO2, but then that gets blown away by the solar wind. It's crazy hard to fix.
Don't get me wrong, I would love to see us on Mars. Unfortunately, the engineering and science obstacles are huge, enormous.
> Unfortunately, the engineering and science obstacles are huge, enormous.
Yes, I agree we should go to Mars. I don't see the urgency, though. I mean, in terms of the humanity-backup situation, ten years or a hundred, doesn't really make much difference.
We would be better putting the money into energy research, and when we've got that figured out, then we tackle mars.
For Bash, M-# (alt-shift-3) puts a comment token '#' at the start of the current line and begins a new empty line. Handy if you are 150 characters deep in a command and realise you need to do something else for a moment (i.e. momentarily in the correct sense). You can store your 150 char command and come back to it, it is in the history and can be retrieved with a couple of Up-arrows.

Yeah, that was my first thought when I saw him interviewed. He had no empathy at all. He basically admitted he ran a shady business that monetises peoples' misfortunes, but, hey, if he didn't someone else would. As if that justifies it, somehow.
I have four VPSs, mostly on different hosting companies. 99% of ssh attacks come from China, the rest are eastern Europe (mainly Romania or Ukraine) or Brazil.
The Chinese attacks use a group of about 15 IP addresses, then, every so often, they all change the addresses to new ones at once. This has just happened, last week, in fact. So now I have dozens of attackers all coming from a group of about 15 IP addresses, which are different to the 15 or so IP addresses they used a couple of weeks ago. (No kidding, the regularity that this happens, it would not surprise me if their military is training a new class of crackers and has been assigned a different set of addresses to use this term.)
When I get a new IP address in the log, I do a whois and rewrite the "inetnum:|NetRange:" field to a class A|B|C address and then DROP it in iptables. Fuck 'em. The whole darn network class gets dropped. Not that I'm likely to be logging in from China any time soon anyway.
I now have a list of network classes with about 35 address ranges that get dropped, if anyone is interested in the list.
Exactly. Henry Ford paid his workers very well, not out of altruism because he was the one of the most unaltruistic people you can think of, but because he wanted them to be able to afford his car. They would become mobile advertisements of his new technology.
In that, they were much like the Google Glassers are today.
