The Amiga kernel was called Exec, and it really is a micro kernel. It might have been realtime as well, but I'm not sure about that. Realtime is overrated anyway. The C-64 was realtime. Realtime doesn't mean it's fast, just that a process is guaranteed to get cpu time within some amount of time.
One of the reasons that Exec was a blazingly fast micro kernel is that there's no memory protection of any kind. It's a lot more difficult if not impossible to come up with a micro kernel offering full protection and an efficiency anywhere close to that of Exec.
You say that games bypassed the kernel. Maybe some did, but are you sure you know what the Amiga kernel is? It's not Intuition, the user interface. It's not even the file system. You can bypass all that and still make use of the Amiga micro kernel.
Wouldn't it be wonderful if somehow this whole music revolution would result in those "top acts" disappearing, and the real creative artists standing up... I think it could happen: without the record companies we have today, greedy producers might stop grabbing dolls from the street and training them for one year to become spice girls.
This only works if SDMI would encode songs into files of 17 gigs.
The point is that if you can play SDMI on your pc, then it is possible to catch the raw audio stream, and if you have that it's easy to make an mp3 out of it.
At least in Holland, the collective music industry has formed one big monopoly that has been overcharging people forever. It is a fact that cd shops are threatened whenever they try to sell CDs for a price the distributors think is too low. It's very much like Microsoft, except that our DoJ isn't doing anything about it (there have been announcements of criminal investigations, but nothing ever comes out of that).
A while ago the industry announced they are planning to do something about those evil people who will buy cheap CDs when they are on vacation abroad. And last week they demanded a 5 guilder tax on blank CDs of 2.50 guilders.
Stealing is wrong. It is good that parents teach that to their children. But as children grow up, they learn there's more than black and white. Sometimes stealing is the right thing.
Scripting common tasks is more of a CORBA thing, IMO. That should be solvable, or they're not really using CORBA.
Of course KOM/Bonobo (I don't think it's called Baboon anymore) interoperability would be ideal, but that seems unlikely to happen. Two variations of CORBA are still CORBA, but KOM/Bonobo have fundamental differences, or so I think.

Reiserfs Released

Actually, I think it's more like Kaffe. Qt is released under two different licenses, but it's just one source tree. Kaffe has a free GPL'd version, and a commercial version, and it's not legally possible to keep both trees the same. (Unless you only accept patches from people willing to transfer the copyright.)
At the moment there's just one reiserfs. If people start using it, this will change. The community only has to deal with the GPL'd version, but Reiser must maintain both and save his legal butt.

Reiserfs Released
·
· Score: 1
Let's say Sun decides to include reiserfs as part of Solaris. They will most likely not want to GPL Solaris, so they'll pay to get reiserfs under a different license.
And of course people or organizations might pay for support, or to have Reiser and his team implement certain features.
I don't know how easy or difficult it will be to make a living out of reiserfs.
If you write a piece of code, you (or your boss) owns the copyright. If you own the copyright you can release it under whatever license you like. For example to the community under a GPL license, and to paying customers under a different license.
If reiserfs gets included in the kernel, and the kernel developers modify it, these modifications are applied to the GPL'd release, so fall under the GPL again. Reiser won't be able to include these patches in his commercial version (unless he explicitly asks for and gets permission).
Distributions can include the GPL version. No deals are needed at all. I have no idea where you got that idea from, since GPL is spelled all over it.
Anyway, just to reiterate, since you're not the only one who doesn't understand (I'm thinking of a certain BSD advocate who recently tried to crush the GPL using very false arguments): if you release your code under the GPL, the GPL only applies to that release. You are still the owner of your code, and you can do with it whatever you want. (But of course you can't retract the release itself.)
If memory bandwidth is not an issue, then the percentage for 600 would be exactly 600/550 times the percentage for 550.
For integer performance this is the case: 118 is very near to 109*(600/550). So this test fits in the K7 cache and increasing the bus speed won't gain you much.
For the other two tests, the result for 600 is significantly lower than the expected value. So bandwidth is an issue here, and running the bus at 200mhz will boost performance.
About the difference with a P3: since the K7 at 200mhz won't do better at the integer test, and, for all I can tell (I don't have enough information here), the P3 might benefit from a busspeed of 133mhz, the difference in integer performance would actually be less with the K7 at 200mhz and the P3 at 133mhz. (If you don't get this and suck at math, then just forget what I said.)
My post was confusing. The first part is about using an X server to display apps running on a Linux box.
The second part was not entirely related. What I meant to say there is that in windows you can replace explorer.exe by something else. And yes, explorer is not really the window manager, but much more the gui/shell. But replacements include enlightenment and afterstep clones, and those are generally considered to be window managers (although strictly speaking they do more than just managing individual windows). As far as I know, there is no way to change the title bars of standard windows applications. That;s what I meant to say.
And indeed, some X servers allow you to use alternative window managers, and these do take care of the title bars and such. At work I'm using Hummingbird Exceed, so I can do that too (although I am letting MS-windows manage these windows).
This last week I've installed Linux on a computer in our lab, and thanks to the X server on my NT box I can now live a decent life. It not only looks really cool to have the gnome panel there in the corner, but it works perfectly and is fast. I've seen windows apps display on remote NT boxes, and I can tell you that's not nice.
About the MS Windows window manager: you can replace it, and there are several alternatives. Unfortunately, the title bars and dragging of windows is somehow provided by the application process, and I'm not sure much can be changed about that (unless MS goes Open Source).

I have a modem/ppp connection, and sometimes when somebody is getting a file from my computer through ftp, my network comes to a total stand still (except for the ftp tranfer in process). I can't even ping other hosts anymore.
This happens at least with 2.2.7-2.2.10. It is reproducable with one person whose connection is slirp-like through a Digital Unix box, using netscape. I don't know if it always happens with passive ftp. I do know that it doesn not happen with regular ftp (from other hosts) or http from that same Digital Unix host.

That explains why this article got posted at all. Except for the BeDope link, everything had appeared in yesterday's article already.
Roblimo, instead of trying to not look as an idiot, just add an update like Rob always does, and admit you goofed up. Revisionist history is scary.

Send the artist $0.25 for every illegally obtained song and he would be more than refunded.
This only works if SDMI would encode songs into files of 17 gigs.
The point is that if you can play SDMI on your pc, then it is possible to catch the raw audio stream, and if you have that it's easy to make an mp3 out of it.
Oh, but do not forget they donate a few % to the artists...

In Holland, @Home measures it in webpages/minute in their ads...
Can you tell more about this? Would it need support from the kernel to get the most out of this?
Compare the results for 550mhz and 600mhz....
If memory bandwidth is not an issue, then the percentage for 600 would be exactly 600/550 times the percentage for 550.

Very interesting comment.
All I'm saying is that saying that Linux is free and NT costs $$$ is NOT a very good argument.
IIS is not in the kernel on NT, but NT does have some very specific system calls that are great for serving static webpages.
And the Linux developers are actively working on deserializing critical paths. 2.4 should be a lot better in this sense.
You're saying that Linux + 4-way beats NT + uniprocessor in price?
