I get the impression that implementing a 28.8Kbps+ modem pretty much uses up the capability of a near-state-of-the-art DSP chip. Further, recently an item appeared on CP concerning a new voice-compression standard that was claimed to put good-quality voice into a 2400 bps stream. Each function, coding and decoding, was claimed to occupy about (don't recall the exact figures) a little over half the capability of a TI 32025 DSP chip, which admittedly is an older unit. Assuming full-duplex is desired (and that's the purpose of this exercise) you'd need the full resources of something with greater 'ooomph' than a 32025 just for the coding/decoding. Sure, it may not be necessary to compress voice audio all the way down to 2400 bps, since the current modem standards allow 28.8kbps and beyond, but I suggest that decreasing net traffic by a factor of 12 (28.8k to 2.4k) is a desirable goal. Remember, in the long term "everybody" will be using Internet telephone. (And no doubt you've noticed that high-volume hardware gets cheap, really fast. Putting in a second DSP for compression/encryption won't increase the costs all that much.) Leaving the encryption in hardware would improve exportability, at least from a legal/ITAR standpoint. While eventually full-fiber-capacity Internet will be able to increase the capacity to "unlimited" levels, in the meantime the capacity is limited (by switches if nothing else) and going the extra mile to limit Internet telephone's impact on the national net would be better. >With the right drivers you could use >the telephone/speaker/mic jacks that are on most of the integrated cards. > Also, they have a standard realtime OS with most of the functions being >portable across cards as well, so you'd have to do very little work to >support other Mwave cards. The reason I think a system I've described has a future is that modem manufacturers have a PROBLEM. Their problem is that they've pretty much run out of room to improve the bit-pushing through a 3 KHz bandwidth. Sure, they can focus their attention on cable modems or ISDN units or other toys, but the market for such beasts won't develop for a few years. They'll pretty much be stuck doing an occasional upgrade, or selling into new computers, but that will slow down. What they'd like to have is a new function that "everybody" wants to have, and allowing people to bypass LD telephone charges is a powerful motivating factor to get people to upgrade their modems.

-----BEGIN PGP SIGNED MESSAGE----- SecureDrive Users: It's been brought to my attention that the detached signatures for two executable files in SECDR14B.ZIP don't verify. COPYSECT.EXE FPART.EXE These were supposed to be identical to the 1.4/1.4a files, so the same signatures were used. It seems the files were inadvertantly re-compiled with a different version compiler, hence the mismatch. Anyone concerned, can use the files from SECDR14A.ZIP, which are still available, and should match the signatures. It's also been said by a couple of correspondents that the listing of CRC values from PKZIP could be easily counterfeited.

Crypto added to anti-terror bill in US at last minute?!?!!

>From ACLU's site: http://www.aclu.org/issues/cyber/terror.html The latest understanding from ACLU's legislative representatives is that the "Anti Terrorism" bill that is expected to be acted on today and tomorrow will include government controls on encryption -- a scheme for key escrow of private keys for encryption. It is also likely to include expanded use of wiretapping without a Court order. --- No-frills sig.

Pipe bombs vs high explosives.
by James A. Donald 17 Dec '03

17 Dec '03

Does anyone have any experimental information comparing an untamped high explosive with a pipe bomb? A pipe bomb is a device for getting a decent explosion out of a low explosive, such as gunpowder. A low explosive combusts relatively slowly. The purpose of the pipe is to hold it together for long enough to get decent pressure. Homemade low explosives tend to be even more feeble than manufactured low explosives, because it is inadvisable for amateurs to recorn their powder, with the result that home made powders burn slow, whereas homemade high explosives are just as effective as manufactured high explosives. My theoretical expectation is that pipe bombs would be very ineffectual when compared to high explosives, especially using home made powders. Note that very large pipe bombs can be made by using propane cylinders or compressed gas cylinders in place of pipes. --------------------------------------------------------------------- | We have the right to defend ourselves | http://www.jim.com/jamesd/ and our property, because of the kind | of animals that we are.

In addition to the possibility of reloading them (and saving a bundle on ammo costs) you can sprinkle them around liberally in the aftermath of an encounter (assuming you survive) and give the crime scene people a bunch of red herrings to deal with. Of course, you should never touch them, (the FBI got DNA samples from stamps the Unabomber licked on his mailbombs, so even tiny droplets of sweat can bust you) and you should collect the actual brass fired and sandblast it. Incidentally, one of the interesting traits of a shotgun is that buckshot is not subject to the ballistics matching techniques used on rifle and pistol bullets. The plastic wads (which prevent the shot from touching the barrel) do not take the microscopically detailed impressions from the barrel that copper or lead bullets do. The heat from firing always melts the plastic slightly--enough to defeat this. Of course, if you leave the fired shells lying around, the primer and ejector marks can bite you... > FOR IMMEDIATE RELEASE > > MICRON COMMUNICATIONS, INC., ANNOUNCES AGREEMENT WITH THE FEDERAL > AVIATION ADMINISTRATION > > Boise, Idaho, August 2, 1996 - Micron Communications, Inc., today > announced a Cooperative Research and Development Agreement (CRDA) > with the Federal Aviation Administration (FAA) to develop a model > Positive Passenger Baggage Matching (PPBM) system.

USPS has proposed that the new postmark contain a unique digital signature carried in a 2-D bar code. A new indicium substitutes for a postage stamp or postage meter impreint as evidence that postage was paid. Because of the information the indicium will contain, the agency will be better able to deter amil fraud as well as provide additional services, such as mail tracking and tracing, according to Roy Gordon, program manager for the agency's Information Based Indicia Program. 'USPS' inidtial strategy is to sample [letters] in the mail stream and scan on a random basis,' Gordon said. 'In the long term, it will scan 100 percent of the mail to deter fraud.
