The problem with a fileserver (from the students prospective) is this:
1) A fileserver can be accessed by anyone, including the prof. Prof changes testing format, old test value is degraded or lost
2) Fileserver with access permissions won't help because it is still connected to the univeristy network and the prof can have IT manipulate it's network however is needed to access the documents. This is hairy and probably encounters some legal issues depending on state on University laws, but could lead to the result of #1.
3) Have local access (console) only. Now it's basically the same as storing the physical papers, except everyone can printout what they need. This doesn't add much value though, so the work to do it may not get done.
You included the magic word "managed". To add that to a switch could easily add another $200 per switch, which may break the bank to many people. If you can afford it and know network management fairly well, i agree. But a hub will give you this ability and _reduce_ the cost. So I guess it's a matter of what tradeoffs you can live with
So, when you connect to an open webserver (yahoo,/., etc.) is it criminal to connect to it if the admin hasn't granted you specificly to access the computer? No, it isn't. So, why should any other service be different in the eyes of the law? Any service that is left open to the public for access without authorization can't really be prosecuted under this law. This would include telnet (MUD's), www, FTPanon, _open netbios shares_, gaming servers, and anything else (including open relays).
Despite the fact that port 23 and 110 are open, it appears they are explicitly refusing connections on 80
So they probably saw the hits going off the scale and took the webpage offline (or firewalled it off to outside connections), I bet the box handles things other than web (which makes it a Bad Thing if the entire load is being used by Apache)
I think for most of us, the value of information depends on how much time we spent customizing or creating it.
Someone who has spent years customizing their system will put more value in/,/etc, and/usr/local, etc. Those of us who run default distro setups will be more defensive of/home and other directory archives (MP3 dir's,/usr/local/games, etc.) becausing a simple reinstall of./ or/usr directory is easy with an install CD
It will only work for as long as the heat/energy contained in your finger is high enough to maintain boiling the liquid before it begins to cover your finger. After that point, your finger will quickly become like the raquet balls, pens, and other items that get shattered for demonstrations.
Your finger has an advantage in that hot blood gets circulated to it, so it generally can boil the N2(liq) for longer than similar sized inanimate objects.
I personally run my own email server with qmail. Qmail allows all users to set up aliases in some form fairly easily. All you do is set up a bunch of aliases that point to your main account. When you start getting spam on one, you know who you initially gave out the email, and then you can cancel the alias to keep getting spam from those people in the future.
I'm pretty sure sendmail can do this also. It's worked well for me so far.

It is this very debate that has confused me for some time. Despite the fact that this perfect replica would be absolutely indistinguishable from you, it would only be so to anyone BUT yourself. To me, this is alomst like the scientific proof of something similar to a soul. (A really weird concept for someone who does not take kindly to church)
It would be reasonable to assume that you would want the new person to be created before the old was destroyed (in order to verify any possible transfer issues). Suppose the process was stopped before the origional was destroyed. There would be 2 version of you that are indistinguishable, yet to the origional the duplicate is always the obvious duplicate. It suggests there is on some level a human perception of an individual that cannot be duplicated. Since you can't have exactly the same experiences from this point on as your duplicate, you will begin to differ (nature vs. nurture) and thus eventually be able to be distinugished... but for those first few moments after the process these differences will be at a minimum, and perhaps negligable.
Anywho, I believe the article referred to the stopping of light as if not to make it's velocity zero, but to make it's mean displacement over time zero through redirection by diffraction/reflection.
Developing a full organ replacement would still be a ways away. Organs require a lot of organazation in order to develop properly. For instance take the heart. Some cells form the aorti, some ventricals, others form heart valves, etc. It's not just a ball of cellls that have the same type. In fact, some of the heart cells are different amongst themselves. However different organs require different levels of complexity
Aangstrom Biosciences in Michigan, for instance, is in the process of testing a method for producing bone marrow from stem cells. I think they get their stem cells from in the marrow itself, and use a patented method to culture it (which had been impossible before)
I think producing marrow, skin, generic nerve cells (?--may be more complicated), lymph, etc. may be much more within current technological limits than kidneys, hearts, and livers.
You are correct in that the MacOS is not SMP aware, but applications run under MacOS can be compiled that way. Adobe Photoshop is the best known example. There is a SMP library in the Extensions folder that did this as far back as MacOS 8 or 8.1. I've heard it's a pain to do, but do-able. I think distributed.net clients for MacOS can use the other CPU also (though you wouldn't probably buy a 2nd CPU to get your rc5-64 rate up).
Also, who says your going to run MacOS? LinuxPPC will recognize and use the other CPU, as will BeOS PPC (though Apple has not been kind about supplying details regarding the new Mac's, see their web page for details). LinuxPPC also let users access slave IDE drives before the MacOS could as well--it's handy for recognizing other devices that are not supported under MacOS (tape drives, Windows PCI cards, etc.).
I've driven past the Chimney Rock Rd and Woodway intersection while experimenting with ways to get home from work. According to Mapblast, they are not to far west of that spot.
I can stop by sometime during the next couple weeks and take a look. Email me at xmas00 at hellgate dot homeip dot net. I may have messed up the qmail services running while experimenting with httpd yesterday so don't be alarmed if the email doesn't go through till sometime this weekend.
I checked their site, and I cold find any information regarding if you could run programs locally through Xtools. Technically MacX did everything you claim, but it still needs and UNIX server somewhere the run X and send the display back to the Mac. The disadvantage here is the files on the Unix server are not the files on your Mac (unless you have an extravagant netatalkappletalk setup going), and the network slows everything down (and MacX takes a crapload of RAM, though all X servers do I guess).
I never used the product, and you mentioned you did. Just pumping you for info:)
FYI: netatalk is like Samba's filesharing, but for Appletalk/Macs. Also does printer-serving, i think.
It's been awhile, but let me see if I can help enlighten you...
If you are looking for Linux only and have no need for MacOS compatability or native support for the PowerPC's CPU instruction set (also found in the many objects that use PowerPC embedded processors) then there probably is not much reason for you to.
Apple PowerPC's are expensive comparaing hardware to hardware with a BTO i386 option. However, IBM has released a free mobo spec for other companies to make a PowerPC computer with, and they could probably compete with the hardware prices for an i386. The Motorola PowerWave and the BeOS boxes are PowerPC computers that can run LinuxPPC, but are not Macs.
The Mac costs more because:
a) it's Apple branded
b) it includes all hardware certified to run under just about every version of MacOS
c) Much of the whole computer include things that many other computers (except Dell, Compaq, etc. BTO workstations) will not, such as a NIC, video, sound input/output, and firewire. These options are on board (except Video, which is AGP) and not removable.
d) It includes ROMs (or something to point to a ROM file on the HD) and a Forth BIOS (OpenFirmware). Apple puts R&D into these items and passes the cost on to you by marking up their computers.
The hardware Apple uses is not all propriaterary. Macs use IDE same as other computers, and other drivers for other parts can be obtained by looking at the chips inside the mac. the PCI bus is PCI standard, and the cards are mostly the same as you would find for PC's (with some exceptions). Most of the propritariness comes in the BIOS drivers (though OpenFirmware is based on Forth, which is fairly open. I think it was started by Sun Microsystems) and the ROM initilization items. these items are mostly needed for the MacOS to operate properly.
LinuxPPC for me has been every bit as stable as the RTHL I have on my AMD computer at home. Plus the devices are mostly the same. Serial ports still show up at/dev/ttySX, etc. In fact, most programs that are source code distributed can be recompiled under LinuxPPC easily. There are issues sometimes with machine-code optimized programs or things that may get muddled by the big-endian PowerPC vs little-endian i386, but I have not seen many in my experience.
You can run NFS, ssh, etc. between LinuxPPC and Linux i386 systems same as any other. It is truly the same OS on top, just _some_ of the hardware underneath is a bit different.
One of the many reasons I like running LinuxPPC on my Mac because it lets me use hardware that the MacOS won't let me because it came in a PC box. I have a NE2000 and a DEC chip 21040 NICs in my StarMax. The only times I have a problem is with video cards because the primary video card must be recognizable by OpenFirmware so the display can come up at boot.
It is sarcasam. Just a funny to brighten your day; though I learned about localhost from some guys on USENET that convinced me that Marathon IV's test server was running on 127.0.0.1...

Technically, I believe the answer is Yes-No to both. Snakes (though not all) are the obvious choice for IR vision with their heat pits under their eyes (commonly mistaken for nostrils). Deer can see in the UV spectrum above what humans can percieve, but not "true" X-rays. I don't think anything can percieve a true x-ray wavelength due to the damage such high energy photons cause living tissue. Many hunting vests use low UV reflective dyes. I think this is why those bright orange vests don't attract attention to game. They are out the game's color wavelength range and are tuned to stay that way while still being bright to other humans for saftey reasons.
If this is a concern, why can't you just use your own systems? ssh (telnet) in to your own box and use mailsystem stuff there. No files, etc. are kept on your (company owned) computer. And if security is a real concern, do use a mail name/nick that is not obviously you for when the company scans through other people's acocunts you may have been sending to.
The only items you need to do this is a smtp/mail-handler, a domain (check out www.dyndns.org for dynamic IP's) and a 24/7 account of some sort. There are HOWTO's for setting up sendmail, qmail, etc.
Plus, you don't have to worry about a mail quota:).
therefore, it doesn't build up speed as fast while falling. Plus the airbags have to be tight to keep you from whiplashing anything, which probably means you will not be able to breathe.
For fan-based aircraft, and autorotation system would probably be best (unless there is a blade problem)
I would like to patent the notition of producing and object called a "Patent" to protect my rights in a court of law. Despite the fact that this has been done in the past, since no one else has patented it and I have a huge legal team that can lobby my initial draft of this document around 1776, I will proceed to claim all current patents as my own.
Anyone attempting to post a patent to this forum will be sent sleaze and dissect orders as nessesairy. Consider this your written warning...

The primary reason this is so fasinating is not because of mass quanities, but because of the new possibility of manipulating bonds on molecules. This has many potential uses:
1) Taking two reactants and manipulating certain bonds by hand may give more insight to why catylists work on similar reactions. Many catylists work without us knowing a great amount of detail on how they catylize a reaction. If certain bond manipulation cauese a reaction to proceed, it is likely that the catylist is weakening that bond--a clue to what is actually happening.
2) Intermediates. Some reactions (esp. in biochemistry) proceed without a good working knowledge of what intermediates form and what changes take place in getting to the intermediate (and so) onto allow the products to form.
3) Rare chemicals. There are some reactions that entropically / energetically make sense to occur, yet don't react because of other variables (such as bond tension--i.e. the formation of cyclo-pentane from larger molecules, etc...i know this is a baad example, can't think of something better). This gives us a method to try to understand and produce them, though not in bulk.
Besides, it's the Chemical Engineers responcability to do bulk production of anything anyway. Chemists just get to do the fun stuff and take all the credit. ChemE's are the ones that put it in the hands of John Doe.:)
