SSI would be when multiple connected computer running an instance of, say, dragonfly bsd, can act like a single (multi-user and multi-tasking) computer. Tasks will migrate to any processor core in the cluster (and ideally factor in the cost of migration over network).
Similar to what openmosix did for linux ages ago - and very different from the infamous beowulf cluster.
By the way - Hammer does not only do simple snapshots but it does them automatically in intervals. So if you use it with samba or nfs you get sort of an instant apple time-machine workalike - albeit with deduplication and all. Only disappointment for me was that trying it in a VM was not really going well - you need a spare PC for that.
Yeah, OSnews has mostly become a mobile website, but I still enjoy it more than Slashdot nowadays.
while many features of ZFS (and Hammer) are included in btrfs too, Hammer (specifically Hammer 2) has design goals that go way beyond those of ZFS (I believe it is going to be a fully fledged cluster FS). So there is something to wait for.
And I am still hoping that theiy will pursue their single-system-image design goal eventually.
I installed a Solaris 10 prerelease on my inspiron 8200 notebook, which is definitely not sun approved, and it (now) works perfectly fine, even with my nvidia graphics card.
I did, although, notice the exact same problems as the original poster (like "eject cd" not doing anything etc.), and it took me quite some tweaking to get X going and to configure a german keyboard. The keyboard config thing is definitely an installers job and differs a lot from linux.
There are some rough edges there (never mess up your X config with xdm login on until you know how to boot into single user mode), and some things are beautiful and quite configureable, like ksh, but not preconfigured worth a dime when they come out of the box!
While normal parachutes are built to open comfortably (so skydivers dont have an acheing back after every jump), reserves are made to open rather _quickly_. A reserve can be deployed below 500m and still slow you down in time before you reach the ground.
The CYPRES emergency opening device for example deploys at an altitude of 750ft (230m). The reserve chute still has enough time to open at that altitude.
Skydivers have a problem that we would not have with our balloon cluster: they deploy at terminal velocity (around 180 km/h, maybe a little more), so at 500m they would only have something like 2.5 seconds left to react. With a cluster of balloons, ideally your initial vertical speed will be a lot lower.
Reiserfs is a journalling filesystem in that it keeps your metadata and filesystem structure intact. Indeed, like any other journalling filesystem it does not journal your data. (with the exception of ext3 with the respective features tourned on). Reiserfs to my knowledge never tried to rescue data. Its simply something you have to know/remember.
... send him abroad for a year, if he`s around 16. There are even scholarships from places like yfu or afs. Dont go with the coomercials. And a year abroad really helps you reflect on culture, society and your place in it. It doesn`t matter where he goes, either. Does not have to be an exotic place. Just make shure he feels comfortable with his choice. He`ll think he knows everything about the place, and maybe that it going to be one long holiday, and then he`ll find out. Kind of stressful experience for a youngster, but cool to no end.

Growing battery-bacteria in your kitchen sounds like one heck of a funny geek-hobbyist experiment. The only thing I need now is an online store where I can buy a few grammes of freeze dried Rhodoferax ferrireducens.
I wonder if you could make it work as a hobbyist. Any biologists here to answer the question if it would be feasible to grow these at home?
Its always sad and annoying to see jokes that werent even half funny fifty years ago still proliferated by a generation that 1. should know better, and 2. does not actually relate to the pun of the joke at all.
it also is sad to read all these constant efforts to compare cultures here on slashdot. Especially if the rating of cultures is done by europeans who really should be aware of the fact that (imho) there is no way and no use in actually comparing or rating cultures, especially not without even looking at the historical reasons for cultural developments.
OK, this is just a thing i think i remember: I thought I read something about hooks or an api for color correction/measurement being already implemented in X, but nobody using it... Does anybody have more specific information?
Yeah, been there, done that. I`ve had same experience with reiserfs and various kernels, but right now Im considering the interactive performance probs to be vm problems really. I havent really tried to test this, though. What does everybody else think?
i still dont understand why a mini black hole would pass through the earth without making a hole or crater of some sort. Arent mini black holes supposed to suck up matter that gets in their way? Then it really should puncture earth while going through it, not?
Guess I dont know squat about mini black holes...
Na, you _should_ use the reiserfs, because if nobody uses it, it will never be properly debugged. And that you shouldnt use reiserfs in a production environment is just a rule of thumb: in a production environment you should _always_ do proper testing an you should also know what you are doing.
I`ve been using reiserfs in production for a long time without trouble, but you have to keep in mind that my servers are usually not running under heavy load. No problem. You also have to know that you shouldnt use software-raid5 at the moment and that you prolly should avoid using tar for backups.
Make shure you know what you`re doing. Read the docs and the mailing list and then go for it. Reiserfs is cool. Its somewhat fast, and its very reliable. And dont ever stick to rules of thumb too closely. Proper testing helps a lot, too!
Exactly. And in lots of places that have both the technology and the money for solar power and fuel cells (like central and western europe) about 95% of the annual solar energy becomes available in the summer months only (western germany: 95% in 3 months, june - august!) and as of yet there`s no halfway decent way to store it until you really need it in the winter.
Same goes for fuel cells: they are incredibly efficient if you use not only the electric energy but also the heat they generate, but lets not forget that in the summer most of that heat will go unused and thus efficency will certainly not be 80%!
OK, MacOS X on the whole looks pretty nice, but there`s one thing I simply don`t understand: why are they using BSD on mach? I mean, I do not understand the benefit mach gives them. Nobody seems to want to run two mach-based os`s at the same time, and on the other hand mach would help with porting the whole thing, but nobody`s going to port this os (+ GUI) anywhere in the near future. Can you enlighten me?
Really, if I was in the security business, I wouldn`t hire a guy who probably spent half of his youth on irc, exchanging Es for 3s, bragging with the machines he 0wn3s and trying to keep "lusers" off the irc-channel.
So apart from that this guy is really really bright and knows his tech? Well, but in a company he won`t be some kind of robot, no, he has to work with the team.
I realise people will say that, no, we are not talking about script-kiddies here, this guy`s a real hacker (and cracker).
I can understand anyone who tries to crack some machines, just because they want to know what its like, but this guy was a big name in the business, and to have a name, you have to participate: you have to be on irc, you have to boast and do other things that your fellow "hackers" expect you to do.
No, I dont think I would want to work with a truly "assimilated" cracker on my team.

I think suse _did_ GPL their installer. And a while ago, too.
I`ve always been longing for a sort of VFS extention for Tarballs or a similar package format. You could put the packages into a special directory without unpacking, and the files are automatically symlinked to the proper directories.
This way you could edit config files within the package by editing the symlink in/etc, and the system would take care of the links when you move the package file.
There would be a tool you could run over the package file to give you information about what was linked where, and you could delete the whole package with a single rm .
Of course, dependencies would still be a problem. But this system would cure the filesystem mess. And it would be easy to use: put the package in/home/username/packages, the files are automatically linked to home/username/bin, ~/etc and so on. Put it in/packages, links go in/bin,/etc,/lib and any user can use them (given the proper perms).
Nationalities, countries and national states as we now them are a construct that evolved during the 17th and 18th century and were precedented by families, tribes, Shires and kingdoms and other forms of traditional rule (whoops, this is getting tough, I hope I can make myself understood... My english...). Imho national states and national identities as we know them are based upon common cultural knowledge shared between (*usually* not very) different ethnic entities.
Basically a state or a country are based on some sort of agreement between the people of the given country and the respective group or person in power who wield power based on e.g. charisma, birth, legitimate rule (elections...).
What they all have in common is a monopoly on the legitimate use of physical force on ots citizens or others. You do (at this point) not have this with corporations. They also provide a deal: citizens have to obey to the given rules, and in turn receive secutity. Security against external powers, like other countries, and security whithin the community through the set of rules they should obey to. Its a whole different story just how these rules evolved and wether they are legitimate in any way. You could argue that you can find different sets of rules and corporate culture in different corporations.
Now I am therefore not shure if a company could provide all this, thus replacing nationalities. After all multiple companies can exist in the same territory and have to obey to the laws and the government of that territory (to an extent, I mean that`s exactly what John is arguing).
What`s interesting about this idea is that you do not get to choose your nationality, and you also do not get to choose the culture that influences you most. Even If you go abroad later, a lot of cultural influence of the place where you grew up will stay with for you all your life. You do get to choose your place of work (well at least I hope so... to some extent...), and thus you get to choose a certain corporate culture and work environment, which could be positive.
BUT you do not grow up in a corporation, and neither you nor your family spend their entire time in your corporation, which does not make it a real choice in cultures.
The rise of international corporations could actually weaken the national states and there could be a chance there and problem. Apart from many people considering any change a bad thing. But I guess if international corporations rise in power, they will somehow have to provide a greater share of the services that were formerly provided by other, now weaker entities. This is a big problem, because: Why exactly should they do that? Who will make them do it? And corporations get to choose their own members: They do not want just anybody.
OK, I`ll stop here, there`s a lot to think about there. Remeber, I was just typing away, so go ahead and rip it apart:-)

OK, well Be *was* at CeBit, they were just not showing off anything but their appliance stuff.
And yes, CeBit is a (sort of) consumer trade fair. A big one. Tres importante. At leat its not a conference.
And even if it were, an OS needs applications, and apps need developers who need to be convinced to develop for that OS.
And maybe a company has to share its plans about the future of one of their products if thy need third parties like developers to make it a success.
When I saw Be`s booth at the Cebit earlier this year, I was very intersested in seeing Be0S at work, but it was nowhere to be seen! They only had a couple of handouts with some internet appliance blurb on it.
I mean from how they displayed their OS (like not at all) I would neither develop for it nor make hardware drivers or anything.
And they simply denied dropping development, too. Not a single sentence about having future plans or a strategy.
(apology: I didn`t look at their website before writing this, its just my impression)
I`ve been using reiserfs for some months now (~3)and its been rock solid! I mean, sometimes when it gets really late at night, I really just hit the power button without any shutdown because I want to go to sleep and nothing else. In the morning you just boot up, and thats it.
Just yesterday I had to reinstall win98 and it somehow hosed my lilo, which cant be resurrected by all means. And now I have this perfectly working installation and cant get to it ( Imean not easily).
I mean: hey, try reiserfs. I`d even put it on a small, low volume production server, you just have to remember not to use it with software raid5 (raid 0 and 1 are OK afaik).
