Ballmer: Microsoft to go after Linux strongholds (ZDNet)Ballmer: Microsoft to go after Linux strongholds (ZDNet)Posted Oct 22, 2005 1:00 UTC (Sat) by ncm (subscriber, #165)In reply to: Ballmer: Microsoft to go after Linux strongholds (ZDNet) by cross Parent article: Ballmer: Microsoft to go after Linux strongholds (ZDNet)
... but don't blame Portugal.
mmarq, please take the time to condense your thoughts into the most concise, clear and relevant text you can post. Otherwise, thousands of people must each do the same work to try to extract your meaning. Many (myself included, I admit) tend to just skip past your postings; if you didn't care enough to condense and clarify your thoughts before posting, why should any of us care enough to do it for you?
That goes for everybody else, too. Yes, you. :-)

It makes for a very distracting reading. If you really have to stress the occasional word, make use of HTML resources like italics.Good writers only emphasize individual words, as a grammatical resource (to display focus); it should be used sparingly. Stress should not be there to attract interest -- if your words alone do not deserve attention, do not write them.

If the sentence doesn't read right without the exclamation mark, chances are it's better left unsaid: not surprising enough, or funny enough, to be worth the reading.On the subject of focus, consider (from the soap opera actress, in John Sayles's movie "Passion Fish", pondering how to play one of her assigned lines, presumably post-UFO-abduction): I didn't ask for the anal probe. [must have been somebody else]
Style and form Posted Oct 22, 2005 22:35 UTC (Sat) by mmarq (guest, #2332) [Link] Thank you for the good intentioned remarks. I honestly try do to better next time. Never the less, its a pitty there isn't none related to the issues i brought above namely:
NX (for distrib. computing)http://freenx.berlios.de/
and last but the most important, new model for a completely free of virus and crackers platform, which is achievable with a exokernel benneth traditional Linux, since exokernels are perfect and natural structures for full capability systems and some hard real time configurations;

Sometimes it may seem that i'm doing it on purpose. But the fact is that some very good and future seeking issues, brought into this forum by many people, are invariably left untouched. It seems that there is fear of departing from the official views. Me thinks the contrary! LWN is a perfect site for people discuss new prespectives not code or writing style, and as i type as i go from the simple LWN editor, without italics or other formating tools (dont need), i invariably find myself abusing the marks, to only get remarks of how bad my writing looks... pitty!
Style and form Posted Oct 24, 2005 0:29 UTC (Mon) by njhurst (guest, #6022) [Link] I think it is a dangerous plan to re-implement everything from scratch on the premise that the new design will be more robust or secure. Security comes as much from years of harsh real-world testing as it does from special models. We can probably achieve all that is suggested here by putting the same amount of work into fixing up the existing kernel interfaces and designing tools for detecting bad code patterns.
Auditing also helps, and everytime we build from scratch we lose all the previous auditing work. I say this having spent considerable time working on a security from the ground up system using capabilities (the real ones, not the fake capes that linux has). Time heals many security holes.
I think the general consensus is that we like your posts, but they are a struggle to read. If you wish, I am happy to read your posts before you post and correct the language. (Nevertheless, one word)
I don't think that we have a serious problem with group think here, several times people have corrected popular pro-linux myths and brough us back to reality. If anything I think lwn is one of the least biased linux related sources around. things like newsforge are just full of drivel, slashdot suffers from groupthink to a larger extent and most commercial rags are too heavily dependant on advertising dollars to stay NPOV.

I belive the "Grand Beauty" of putting an exokernel beneath the present Linux kernel, is doing it without having to re-invent the wheel.It could go even to a Single Adress Space design with the Linux synchronization mechanisms, locks, semaphores, because the adress space is mandatory handled by a dynamic library in an exokernel design... as in XOK/ExOS(could be XOK/Linux)
Full *POSIX* support can be achieved in this type of designs as in Meshix and Angel http://citeseer.ist.psu.edu/cache/papers/cs/294/ftp:zSzzS...
"" Security comes as much from years of harsh real-world testing as it does from special models.""
No. I belive its simply proved, so simply that it hurts, that the present model is inherently *INSECURE*, no matter what. http://www.skyhunter.com/marcs/capabilityIntro/index.html
"" We can probably achieve all that is suggested here by putting the same amount of work into fixing up the existing kernel interfaces and designing tools for detecting bad code patterns. ""
Not likely. Building good interfaces and detecting bad code patterns also has to be applyed, but in less extense and without "crazy hacks", to an exokernel/Linux design with capabilities, or better, to an exokernel/Linux with the actual Unix file acess list protection design on top of capabilities, beying it a SASOS or not.
That is an exokernel/Linux design could be full POSIX, have the Unix file acess list protection style available and yet the ensemble behave like a monolithic Single Adress Sapce Kernel... only much much more secure, to the point a * virus and crackers prove* LABEL can be arguably applyed.
"" Auditing also helps, and everytime we build from scratch we lose all the previous auditing work.""
I belive auditing would also be necessary, and even more because in a exokernel design, you could have as exemple the Apache server having its own virtual memory and file system directly on top of the exokernel (achieving perhaps more than 1 order of magnitude more performance) , and so everything from the OS and every application and service as to be audit to *guaranty* safety. Many of Previous work, and followed disasters, *could* be an example of where and why stating secure a system that is *inherently INSECURE* is a bad policy.
Sincerely thanks for the offer, but one of beautys of posting is learning how to write properly and not get lazy.
I also belive group thinking could be much more enhanced then today, by people losing fear of posting more radical ideas.
