At SFTP and SCP if there is noise or the connection fails (what will have exactly the same appearence) you'll end with no file at all at the receiving side, not a corrupted file. FTP will create a corrupted file.
Anyway, from what I've read, he's looking for rsync.
To be fair, backup in general is too hard a concept for most people to grasp. Paid backup more so, and paid bandwidth consuming backup is still worse.
also, I doubt the technical users would be interested on that. In site backups are good enough for most home applications, network backups are too slow for most enterprize applications. Add to that the security problems of a 3rd party maintaning your files and you'll get a solution that is too problematic for widespread adoption.
Too much brains for me. Unisson needs to first look at every file and see if there are changes, only then it starts syncing. That completely breaks things on unreliable low speed links and on the reliable hight speed ones I use file sharing, thank you.
"I find NFS performance is barely acceptable (probably not acceptable to most people) over an old 6 mbps WIFI card my kids' laptop uses."
That's a funny thing to say. There is no file protocol that will give you better performance than NFS. Make sure you didn't disable caching, that you are following a straigt route from laptop to server or that the server isn't overloaded.
As a side note, I find it quite useable over the 1mbps WIFI link I use at home, but file sharing in general isn't very convenient to use for laptops, since it does not fit well to what I expect from my firewall.
If you file server dies, you put the disk on another computer. If the disk dies, you restore your last backup. There is no solution as convenient as a centralized file server, even if you are using Windows (that can't handle file sharing that well) it is still better to keep things centralized on a server. For that NFS is a great choice at a home network.
Now, there is no solution for keeping our files as safe as making backups. Synchronizing several disks isn't even nearly as good. If you don't want off-site backups, I'd recommend using rdif-backup on a different server at the LAN. Schedule the backup routine at your file server, make it turn the backup machine on and off at start and end of the task, and set the backup machine to send email alerts when it get any SMART error. That is as close as a set-and-forget setting as you can get for backups, once in a while you must look if the backed-up data is on the right place, and that is all.
Well there is a difference on how much of the energy you gather from the Sun - Earth temperature difference and the Earth - Backgroung temperature difference. Theoreticaly, you could use all the energy from the Sun 2 times.
There is also nuclear, like a previous poster said.
"What makes you think that if they opposition was successful in their political ambitions that they would become pro-American?"
That is the kind of thing that creates anti-american sentiment. Souldn't you be expecting a party that is pro-iranians, instead of pro-America?
And yes, every pro-America dictator that the US has put in the middle east turned anti-America as soon as the circunstances made it more luvrative. Only a fool would expecting a different behaviour.
Slax is a small live-cd Linux based on Slackware. It's newest version is 100MB big, but I have an old 50MB iso that I can make available. If you have installed those tools by scratch, you'll need at most to recompile them at Slax, if you installed them by apt-get there may be some problems hidden at the instalation... If you need some help installing them, I can help you.
You can get my email from my profile. I'll see if I can get a smaller live distro.
But anyway, I must support the previous post that said that some aspects of computer science use empirism. He just got the wrong aspects, if you look at artificial inteligence, you'll see lots of it.
"This is not to say the RIAA won't do this. just that it would be illogical."
That is good that you finished with that line. By their history, we can expect the RIAA to discredit that study, but you are right, it would be completely illogical.
"DRM has its uses in business with rights managements on documents..."
Let me fix it for you: DRM has its uses hidding evidence in business and government corruption more than it has uses limiting the freedom of a consumer...
As I just pointed on a previous thread, you can always break DRM while the authentication server is running, but there is no guarantee you'll be able to break it after the server is gone.
Except that there is no guarantee that you can crack a software after the authentication server goes under. You can always do it before, but only weak DRM makes it possible to do it after the server failure.
On the fly error checking. Really, that and go to function definition (somehow with a keyborad, while a click is acceptable for Eclipse, it will be quite out of hand at Emacs).
It didn't got any better. Eclipse C++ is still slow, full of bugs and hard to use. It is also still one of the best C++ IDEs available for Windows.
To be fair, that entire IDE concept applies to Java quite well, but has some problems when applied to C++. It is quite hard (would require a very good AI) to read a bunch of macros and discover that, since the developper likes Pascal, they rewrite the C++ language, for example. Hell, C++ compilers can't even point the line number of an error sometimes.
"VIM is powerful indeed. But one should never forget that sizable chunk of its utilities depend on good shell and system file/text tools. Otherwise you probably want to pick Emacs instead. "
As a heavy emacs user, I'd disagree on your assumption that emacs isn't dependent on the shell. Of course, theoreticaly, it is, but why would you reimplement make, grep, find, etc in lisp if they are already there? Emacs can do near everything, even leting bash do the work.

Wait... There are still humans around?

First, random IO is mainly dependent on seek time, not rotation speed.
But we try to not do random IO at disks anyway, currently people are quite good at avoiding it.

Well, all the data, except for their home dirs. But I guess that isn't important when you already have backup of their wallpaper settings.
Yes, at the NFS option there is a yellow pages services implicit. Try NIS, it will sync your UIDs and GIDs.

It is nice to see democracy working the way it should. Normaly they'd just bribe other parties until they get a majority, and then piss people off.
You should check again how much solar would be needed. Hint, it is still a lot, but it would cover an irrelevant part of the world.

The dissidents would probably just steal bandwidth from the allies.
Well, the US could oversee the next elections to ensure that it gets an honest result...
Ok, for irony impaired people and for those that think that would be a good idea. Forget it.
So, it is based on mathematical models :)

Those are the only features worth adding.

Gdb is even usable inside emacs... I mean, you can scroll, and read other files... Just don't forget to kill it before you save!
