  1. PDP-8/E runs great on OS X on Don't Nurse Old Hardware - Emulate It · · Score: 4, Informative

    the PDP-8/e Simulator for Macintosh is a LOADED system (up to 32K words of memory, KE8-E Extended Arithmetic Element, ASR 33 Console Teletype, ASR 33 Auxiliary Teletype, PC8-E High Speed Paper Tape Reader and Punch, RK8-E Disk Cartridge System, LP8-E Line Printer, and a KC8-EA Programmer's Console) that runs a quite a bit faster than the original - fastest benchmark is a G4/450 at about 22x; my 2x1.25 runs the tests well under 1sec. If you need to support an -8 legacy, this seems like the logical way to go.

    [A]strophysicists have a good understanding of the development of the universe only as far back as 10^-34 seconds after the (apparent) singular creation event. What happens before, therefore, remains an open question...This unthinkable void converts itself into the plenum of existence-a necessary consequence of physical laws. Where are these laws written into that void? What "tells" the void that it is pregnant with a possible universe? It would seem that even the void is subject to law, a logic that exists prior to space and time.
    Enjoy.

    the challenge is whether you can successfully gut yourself without showing any emotion, then calmly set the tanto down on the table and bend forward, presenting the back of your neck to the second for the sword blow; if you're going to start screaming like a little girl when your intestenes spill out, the second pins you down and stabs you to death. either way, i'd rather use a shotgun.

    Couldn't you put a small-ish battery in the VOIP box and have it switch over in case of power failure? I realize VOIP hardware is a lot more complex than POTS, but surely a laptop sized battery can keep just a VOIP system running for several hours? in case of prolonged outages, the phone could shut down to conserve power, so you always have enough juice to make a 911 call or whatnot.

    oh, i'm not claiming AES is the NSA's super-duper-tippity-top-secret encryption, just pointing out that they allow for its use, which has gotta say SOMETHING about Rijndael. whether that something is the robustness of the algorithm or the ease of backdooring is left as an exercise.

  9. Re:5.56mm bullets don't usually overpenetrate. on iPod: Your Portable Corporate Hellraiser · · Score: 1

    I totally agree, after having put many a 308 bullet clean through a deer - KE dump, hydroshock, fragmentation, blah blah blah, as long as you make a HUGE FREAKIN HOLE in your target, your weapon is effective (a 168gr softpoint in a whitetail's chest makes an exit wound the size of a cantaloupe).

    I picked that page as a link mostly because it was the smallest, lightest page that had images of wound profiles and i wanted to show the 5.56mm's depth of fragmentation. Matter of fact, I did pull up the steyr scout page from google, but i didn't link it up because it was so dense and information-loaded; i didn't want to bring up the various schools of terminal performance, just the depth of penetration. although i don't mind a rousing debate on the subject (specially since my preferred caliber is 7.62/308, which has no "performance issues"...one hit, one drop...).

  10. 5.56mm bullets don't usually overpenetrate. on iPod: Your Portable Corporate Hellraiser · · Score: 1, Offtopic

    The .223 has been gaining popularity with LE over the years due to the development of frangible bullets - they still pack enough kinetic energy to slice through body armor, which is one of the primary reasons for choosing a 5.56 instead of a 9mm, but once the bullet hits a 'resistant' material like flesh or a wall, it disintegrates into small, harmless pieces. Anecdotal evidence from tactical entry situations that even NATO M855 ball ammo (62gr steel-core) doesn't tend to overpenetrate - the bullet is traveling so fast and is so hydrodynamically unstable that it tumbles and snaps in two after about 10cm of travel through flesh.

    Now, in Europe (or at least Geneva), where the army d00dz have H&K 7.62mm battle rifles, the overpenetration issue is legitimate - a 168gr 308 bullet will blow right through a man like a hot knife through butter,.

  11. Arbitrary USER code execution isn't a ROOT exploit on Security Statistics and Operating System Conventional Wisdom · · Score: 1

    The Safari browser hole didn't allow superuser code to be run, only the particular users code - *any time* setuid is used on OS X, it will pop up a password dialog, and if you're dumb enough to not Cancel an unprovoked password demand, you deserve to be r00ted.

    Contrast this with the Windows (and Linspire...) model, where Joe User is already root, and the ability to run arbitrary user code becomes a lot more of a problem. OS X isn't "perfectly secure", nothing short of a totally unplugged bx is, but it is a hell of a lot MORE secure than Windows.

    yes, there's always a scientific explanation for what goes on in the pan. my point is, from what i've watched of alton (admittedly not a horrible lot), he lays down the science as far as heat+acid+dairy=curdling, but doesnt then go into the varous ways that rxn can be stymied or manipulated to the cook's advantage. example besides the mock beurre, i make a wicked lemon cream sauce for lobster that involves taking rather a lot of butter and lemon juice, whisking in a bit of cornstarch, then adding cream and reducing. again, no curdling, just a wonderful thickening. i'd guess something is happening along the lines of the starch preventing extensive crosslinking and clumping, but i can't say for sure. my point is, the science behind cooking can be so wildly..well, illogical and seemingly non-scientific that it can hamper your culinary progress to be overly fixated on the exact chemistry of what's going on in the pot.

  23. ahh, but curdling isn't as simple as that... on The Thermochemical Joy of Cooking · · Score: 3, Interesting

    That was where i first learned the limits of chemistry as applied to food. it was making a mock beurre blanc. after the vinegar, lemon juice and wine were reduced i was told to whisk in a quart of heavy cream. now, as you yourself pointed out, tossing cream on top of hot, concentrated citric and acetic acids (reduced lemon and vinegar) would result in an instant hideous clumpy mess. oh wait...look, it's really rather smooth...add a bit of butter and beat it well, and it turns into a nice, thick, almost perfect approximation of beurre blanc that can be cooled, frozen, reheated and boiled without breaking! as near as i can tell, the acid-induced protein polymerization (curdling) was distributed evenly throughout the sauce, thickening it, while the added fat from the butter stabilized and emulsified the sauce. Dunno though. Quite a nasty shock, i literally didn't believe it even after i saw it. it tempered my scientific arrogance quite a bit, and was the first in many lessons that taught me that to truly master cooking, one must embrace both the hard science and the soft artsy side of it.

    wow, fast results...i was a bit quick on the draw with that, let me clarify. i dont' have a as much of a problem with alton himself as people like the submitter, who do think that by reducing the culinary arts to the most empirical values, anybody can become an alain ducasse or a masaharu morimoto. like i said, home cookery can be broken down and still yield excellent results for a pot roast or coleslaw, but all the science in the world isn't going to help you make a better shabu-shabu, paella, or cassoulet.

    yes, i am putting on snobby chef airs (which i really have no right to do, i'm just the sous/saucier), but i'm also speaking from the firsthand experience of trying to fuse chemistry and cooking. if that concept really does it for you, try baking - that branch of the food arts really is a science, everything has to be weighed out just right and mixed in the proper order and fashion, or the proper reactions won't take place and you get a limp, flabby cake or gooey, chewy bread. i'm actually surprised i dont' see alton in the bake shop more...
