How to Burn a Magnesium NeXT Cube

Saint Aardvark the Carpeted writes "How do you set a magnesium NeXT cube case on fire? It took this guy two years, *two* cases and the cooperation of Lawrence Livermore Lab's burn cell." A seriously bizarre tale, but worth a read if you're curious. And I have one of those cubes in my office... all sorts of fiendish ideas start.

    I used to shave and burn (DowMetal) magnesium as a kid. Made my own sparklers with iron filings, magnesium powder and sulphur. :)

    On a different note, there used to be a speed week or something up at the Bonneville Salt Flats which would end with a ritual burning of a VW beetle engine block (which is magnesium) and would probably be visible from Mars. Can't find a link tho.

      Yeah, Magnesium alloys typically provide their own oxygen when they burn. Wrong. Metals (alloys or otherwise) do not contain oxygen. However magnesium has sufficient affinity for oxygen that when it's hot, it will rip H2O apart to get more oxygen. That is, spray water on burning magnesium, you supply it with oxygen AND it releases hydrogen gas, which will drift til it mixes with some non-oxygen depleted air, and then probably ignite...

      Yeah, Magnesium alloys typically provide their own oxygen when they burn. This is why you have to use chemical extinguishers to put the fire out. (They will even burn under water as some soldiers in Vietnam found out when their Hueys were shot down and submerged in rivers. "Burnt like the sun")

      As for Bonneville, yeah its a geek fest in its own right. In addition to the hot rodded Studebakers and such, their is some truly bizzare hardware out there. We used to go out quite a bit a few years ago when a friend was racing, to support him and work the occaisonal pit crew bit. Two pits over there was this guy (Norwood or something, but a great guy) who had an 85 Ferrari GTO body wrapped around a tube frame with a twin turbo NASCAR engine in the thing. Strange....... There was also lots of incredibly innovative stuff as well including hydrogen powered, battery powered, some factory stuff etc....

    I can answer this as a materials engineer.

    There is no need to mark it as being a flame risk. The possiblity that it would catch on fire is nil. Bulk magnesium is very hard to burn because it is a very good heat conductor. If you have a lot of magnesium, it is very difficult to ignite, because it conducts heat away. and you can never get any part of it hot enough to ignite.

    If you have a small piece (Like a strip that they use for chemistry demos), there is nowhere for the heat to go, so you can heat it up to the ignition point much easier.

    Why do you think they had to go to Lawrence Livermore National Lab? It is not easy to generate that much heat safely.

  7. NeXT boxes by BWJones · · Score: 5, Interesting

    Remember this NeXT poster?

    "In the 90s, we'll probably see only ten real breakthroughs in computers.
    Here are seven of them." The seven:

    R/W Optical Disk
    The power of Unix (with a GUI)
    VLSI chips
    Postscript (display and printing)
    Digital sound
    Multimedia e-mail
    Object-oriented/visual development

    The NeXT cubes that we used to use were something special. This NeXT poster essentially got it all right, years before its time. Hell we even had a program called zilla.app written by a true code master (Richard Crandall) that allowed us to do distributed computing across platforms (SGI at least). This was back in 1989 or 1990? I think. Wow great machines. I wish I could have purchased one for my own use like the ones in the lab we had back then, but the in our campus bookstore Cubes outfitted like that were something like $10k. But that would get you a completely badass system in all of its black cubeness. Geek coolness was practically sweating out of those things. A Cube with color, an optical drive, one of the sweetest monitors I had ever seen, and best of all a development environment that is still to this day, an amazing workspace.

    Unfortunately at $10k a pop NeXT could not afford to keep making machines, but they did focus on the important stuff. (The NeXT OS reborn again as OSX and Webobjects which I wish I had spent more time learning). As the successor to NeXTstep I have great hopes for OSX (If you have not seen the development environment of OSX particularly the GUI developing environment of OSX, it is pretty sweet.) Here we have it folks, potentially the pinacle of UNIXdom. Time will tell.......

  11. Re:Destroying Art by SClitheroe · · Score: 3, Interesting

    Agreed...Not just art, but vision. The NeXT was a harbinger of things to come (that never did..alas), a bold vision of the future. I remember when there was a NeXT dealer in downtown Toronto. Us developers would go down on a hot, lazy, afternoon and gawk at the absolute beauty and precision of those machines. We were developing on generic 386's, running OS/2 1.3, using Smalltalk. Win95, NT, OS/2, and Linux were blips on the horizon, but there they were..black, powerful, and pure geek lust. They were the most futuristic looking, and most futuristically capable machines out there. They made all the high end offerings (like the RS/6000) look primitive, and made our 386's look just plain pathetic.

    Now, everybody has machines 20x or more powerful, minus the grace and elegance (the iMac cube came close, but cutesy can't hold a candle to how the NeXT Cubes looked back then), and we still haven't achieved the panache, both visual and hands-on, that these things achieved.

    Fortunately, here in Calgary, there is a certain oil company that still runs NextStep, although it is being phased out. Talking to the developers, to a person they nearly cry lamenting their phasing out.

    Truly the passing of a legend. I'm not sure whether to be outraged that the folks in the article burnt one, or to be proud watching a Viking warrior go out in a burning effigy...

    Ok. This is going to come off sounding a little harsh, but here it goes anyway:

    You've never used a NeXT, have you ? You really dont have a fucking clue what you're talking about, do you ?

    1) you didn't read the article (typical)

    2) NeXT machines didn't use X-windows, they used something completely NeXT proprietary. The server process that managed the GUi was called "WindowServer". THe whole GUI was based on DPS. There _were_ Xservers for NeXT, but most were commercial.

    3) what does "fully bsd style" mean ? I bet you couldn't come up with a definition for that that made any sense, but even if you could, it wouldn't be NeXTSTEP or OpenSTEP.

    3a) NS used funky non-unix stuff, like NetInfo (sort of like NIS, but NeXT specific (although ports to other OSes were made))

    3b) NS was not very posix compliant.. there were basic posix things missing from NS

    3c) Many things in NS/OS were GNU software.. they had no issues about throwing away GPL software and replacing it with GNU as necessary.. hardly a very BSDish thing to do ? A notable example is the system compiler - gcc/objc. Other examples include the use of gnutar in many popular next packages (although I suppose this isn't a NeXT decision so much as a user community one)

    4) "handle scsi devices in unix"

    Uh.. wtf are you talking about ? On real hardware, SCSI is utterly brainless anyway. But its especailly so on NeXTs.. you just plug in a device and the GUI pops up a box saying "new disk, blow it away or mount it ?" Whats to configure ? Theres none of this sd0a bullshit, NS just figures it out..

    so, for what its worth, i agree, NeXT boxes are cool and its too bad they were burning them.. 7+ YEARS AGO. And while everyone is entitled to an opinion, your post is like >50% erroneous as far as your "facts", and then you use these "Facts" to apparently justify ranting about something that never happened.

    Nice post, pal.

    I know NeXT boxen are relics from the past, for all intensive purposes, useless. However, they are antiques from a company that no longer exists. They were, in reality, a milestone in computing technology. Superior to everything else around them, NeXT boxes a testiment to innovation (unlike most of what we see today).

    There's a finite number of this machines left in the world, and it's a shame to see such a silly waste. Instead of burning these classic machines, try donating them to people who appreciate them. You wouldn't burn down Abe Lincoln's cabin would you?
