Be aware: that was the old days. Nowadays, most need a business class service just to have port 80 and 25 unblocked. You can't run a web server or a mail server on most customer grade connection because the ports are blocked by your ISP.
I used to do it too. Only risk was that during the IP switch, due to the lag of DNS updates depending mostly on TTL and how server respect it, you may have somebody impersonating your site or grab your mail.
Risk was very slim, the machine that gets your old IP would have to know in advance that it will get your old IP and be configured accordingly.
Minitel and trumpet winsock remind me of a time when the French government, Microsoft and others believed that Internet competing networks would emerge and that they should create their own. Minitel actually had a competing network for quite a while and Microsoft did not believe into the need to include a IP stack in their product.
It's the same way I react to all the melted-soap fugly cars of today. Give the gorgeously creased Giugiaro-styled 1977-1982 Audi 5000 and mark 1 VW Rabbit and Scirroco any day.
Most cars today are shaped like rain drops due to aerodynamic efficiency concerns. A rain drop possesses its shape because it is the most natural aerodynamic shape it can get into to offer the least air resistance possible.
OMG, could have I been right 15 years ago when I perceived sudo as a security hole? Still nowadays, no system I have the last say on have sudo enabled...
In init scripts, to start gpg-agent as root so it runs under user nobody which has a nologin shell, I use: eval `/usr/local/bin/gpg-agent-copy-nobody --daemon`
with gpg-agent-copy-nobody suid nobody: # ls -al/usr/local/bin/gpg-agent-copy-nobody -rwsr-x--- 1 nobody root 1238888 Mar 02 2013/usr/local/bin/gpg-agent-copy-nobody*
I never seemed any gain in using sudo, especially when most sysadmin allow users to do "sudo bash".
Sudo could nevertheless be used in some setup where you really want to manage what users are allowed to do but I have never seen it used as it should be yet. It's like: "we are using sudo therefore we are more secure"
So, in all cases that I have witnessed, you could do "sudo bash". This makes sudo another complex thing to maintain and patch therefore a potential security hole while, in that context, it doesn't protect you from anything compared to plain su.
I actually appreciate that side effect of using "sudo bash". That way, I do not contaminate other admins history files... I don't recall using su without the "-" on non-sudo system having the same effect.
I encountered no issues such as the ones you mention. As long as the files already exist and are owned by the regular user, root won't change the permissions on the files.
I might have used chown a couple times at most on some files that were created by root but I can't recall where, so really seldom...
I just hope they can only see information and have no control from the ground.
Yeah, right, it seems to ring a bell for me, let's see... OK, let's say: like having a read-only access to a web-site?
Hopefully the plane pushes the data if it reports in real-time and the plane doesn't have any listening sockets accepting connections on some kind of wireless network. Pilots could also transmit problem reports through radio...
Ok, I am sick of this. Java is a fine language and platform and it doesn't deserve all the bad press it got lately just because it is poorly managed at the moment in one specific area: browser plugins. Banks and other corporate customers that feed Oracle couldn't care less about the flaws because they use Java server-side.
Here is my theory, I could be wrong...
Sun and Oracle philosophy were pretty different. Since Sun's was acquired by Oracle, Oracle is spilt in 2 camps and stuck with a problem:
1) Sun's former employees. The ones that haven't left yet but that are kind of resisting still from the inside. 2) Legacy Oracle employees.
Sun's employees are much closer to the real old school geeky Linux user style than Oracle employees that are closer to a Microsoft representative in their style. Sun's employees know this, they have also a strong ego.
So making Java look stupid would sure get a stab at those former Sun's employees that think they know everything and possibly make them easier to merge into the company mentality or cause them to resign.
When you bitch about Java, you may just be playing Oracle's game... But then again, could this theory possibly make sense to anybody else?
He could have been using Textpad;-) A lot of developers have problems editing text files with command line Unix tools... Most of them know the "save as Unix" option in textpad although...
I remove the stands and just hang my second row of monitors to the wall with tie-wraps and use rolls of toilet paper between the wall and the monitors to adjust the angle. It works great.
It might be two closely orbiting bodies of rock...
In that case, send the asteroid some closely orbiting space junk that is currently orbiting Earth. They should cancel each other and we get rid of the space junk, win-win.
Yeap, the whole mail system is designed from the core so mail should never be lost as I learnt in my young days.
Managing to loose a single email never mind millions is quite an achievement.
Which VP is he under then, sales?

CEO of SpaceX and Tesla Motors
Holy shit, I just realized it was the same guy although I know a little bit about both company!
Yea, let's talk about bytecoin instead!

At some point, somebody must have built a bridge and a terminal emulator program so you could use Minitel from a personal computer.
Was the technology that proprietary or what ?

Who would redo the same today?
But with a recent headline-stealing dispute between the Redwood, Washington company and Google,
it's competitor down in Mountain Diew, California...

It doesn't work because root has no password set on a typical sudo system.
~# grep root /etc/shadow
root:!:15997:0:99567:5:::
I use my user (not root) password to execute sudo bash. Thanks to the guy who gave a hint about sudo -s!
woosh...

He,he, I kind of never got used to sudo. On all systems I ever had access to, simply typing "sudo bash" gives me the old root shell...
This would make perfect sense ;-)
Hopefully, they meant a TCP/IP connection, not "Internet" connected ;-)

This might work too if you remember to have them closely orbiting together...

In 2000, F5 networks and vmware were already running linux as many others were.
It is just not that well known, they kind of not advertise it that much...
News at eleven...
Linux has been dominating the embedded market device for at least 10 years.
80/20 was a figure of speech that I improvised right of the top of my head. I could have written 50/50 and my post would still make the same point.
Feel free to modify percentages to help you but please stay focused on the core idea.
