2009/2/23, erik quanstrom quans...@coraid.com: this seems dated to me #w, #H and #b no longer exist and the install is now quite different. - erik The book seems rather old and somehow outdated, but I think (meaning hope, since my german goes as far as knowing what a maulesel is) that the main design ideas are there. I really don't expect him to read it, but maybe he does, and he can end up like me (hopefully better than me) lurking around 9fans to get some knowledge out of it. -- Hugo

Re: [9fans] spreding the word
It's got a whole chapter on alef, and the UI is still in B/W. Definitly for an older edition of Plan 9. 'Tis a shame there's absolutley no attribution to be found. I wonder who wrote the book? Seems to be quite readable. Robby

Yeah, looking at it I was thinking that the only Plan 9 book I know of in German was co-authored by Axel Schreiner, who teaches at my school :) Now if only I could read German... John Floren
Re: [9fans] spreding the word
Hello Hugo, 2009/2/23 hugo rivera uai...@gmail.com: Well, I made an obvious mistake and sent the last email to the wrong address. I apologize for that. Some mistakes can be usefull, at least for other people. ;-) In my case I welcome your mistake, because I didn't know that a german document covering Plan 9 exists. Plan 9 is fascinating, but understanding the documents can be quite difficult. At least it was for me as a non native speaker. This is why I keep on lurking around on this list, gathering information mostly, instead of working with Plan 9. This document might be old and even outdated to some degree, but I guess it's still worth reading. It would be great to have the source of the book, maybe it would be worth it to create a community based 2nd release. But I guess with all the copyright issues involved this will be next to impossible. Cheers Christian Walther

But I guess with all the copyright issues involved this will be next to impossible. i can't think of any advantages of 2e over 4e. perhaps others disagree. if you're after the historical progression of how the structure of the kernel evolved, the file server kernel is much more interesting. - erik

Any bits in particular? Any reason why? port/proc.c is very interesting, as are pc/lock.c and pc/trap.c. they are all very interesting as they illustrate the same concepts the pc kernel deals with, but they are substatially simplier. i fear i've complicated things a bit. hardware is more complicated these days. naturally, the fs kernel is less capable. it lacks dynamic memory, for example. but the beauty is that it doesn't need those things. i think it's an interesting study in tradeoffs. einstein said make everything as simple as possible, but not simpler. i think ken's take is that if it's not simple enough, you're solving the wrong problem. - erik
