And in recent news IBM backed away from the Blue Waters program with the NCSA. Looks like they bit off a bit more than they could chew. http://www.ncsa.illinois.edu/BlueWaters/system.html ***** Moderator's Note ***** It sounds like a mutually-agreed-upon tombstone for a project that got out of control. Either IBM tried to pad the specs - a time-honored practice in government contracts - or NCSA realized that they were fighting above their weight: either way, it's very rare for a major player to walk away from a high-visability (and high-prestige) project such as "Blue Waters". I wonder what the straw was that broke this electronic camel's back. Bill Horne Moderator

That one is easy to explain. Americium is a weak alpha emitter. It is used in smoke detectors because smoke (and steam!) can block the emissions of Americium.

Very interesting. I don't think my Samsung Galaxy would hold up too well if it got wet, but my Yaesu VX-7RB is just dying to go out and play in the rain. The latter is gasketed like nobody's busines and is rated to be able to withstand a dunking with no ill effect. The gasketing/water tightness is interesting on that radio. Even the earpiece/mic connector screws down and forms a seal.

Subject: London Rioters' Unrequited Love For BlackBerry Message-ID: <firstname.lastname@example.org> London Rioters' Unrequited Love For BlackBerry BY NIDHI SUBBARAMAN Aug 8, 2011 Rioters in North London have been using BlackBerry Messagess to rally, presuming RIM's phone-to-phone, encrypted messages won't land in the hands of authorities. But in an increasingly familiar move, RIM has now pledged to work with those authorities. ... http://www.fastcompany.com/1772171/london-protestors-unrequited-love-for-blackberry ***** Moderator's Note ***** The problem with organizing against the government is that protesters sometimes forget that governments have tax collectors as well as riot gear: if one doesn't work, the other will. Of course, there are always other ways to encrypt messages, but the fact remains that so long as the crown can identify who sent a message, it can practice rubber-hose cryptography. It will take a while, but the protestors will have to resort to using other means to keep their electronic communications out of Her Majesty's inbox. Bill Horne Moderator

The purpose of the company is to charge money. Providing telephone service is something that they do only so that they can charge money for it. This being the case, the company spends a large amount of time trying to figure out new ways to charge you money. The justification for charging extra, therefore, is that they can charge you extra and you'll pay it. >I pay my provider $X for 2 GB of data per month.

The cost of providing the service has little connection with what they charge for the service. You can think of the telcos as being sort of like vacuum cleaners that attach to your bank account. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

They did the exact same thing which made it REALLY easy to hack into someones voicemail. I clued a friend about MagigJack and a little PERL script proxies the MJ connection and lets you set your Caller ID to that of the cell phone. Then dial the phone via MagicJack and voila, you're in!

You're not "splicing in" to an existing, lit strand. That would not work -- it could be done under some circumstances for wiretapping purposes, but that's not legal unless you're the authorized LEA. What you're apparently asking is how do you physically get service brought in to a building when the fiber passes nearby, right? The general idea is that you need to take a spare strand from the fiber and splice it to a lateral fiber going in to the building. So let's say that the passing fiber has 288-strands. First off, they can only cut in to the fiber where they have some slack, so most fiber providers have slack loops at various intervals. That's what those "snowshoes" up on the poles are for, quite visible in FiOS areas -- about a hundred feet of slack fiber wrapped around two snowshoes facing each other. This slack lets the fiber be lowered to the street where they can easily work on it. Then the technician cuts open the outer sheath, finds the buffer tube (usually 12 strands apiece), opens that, selects the desired color-coded strands, and splices them to the lateral cable. The splice itself is usually done with a fusion splicer, a tool that will set you back at least ten grand for a cheap one. Then it's all nicely closed up and put back onto the slack loop holder. The lateral might well be longer than the distance from your building to the pipe, depending on where the slack loop was and thus where they accessed it. This is pretty standard practice nowadays. If it's aerial fiber, it only costs a few hundred dollars of labor for two guys and a cherry picker truck. Plus they run the lateral to you. Underground is a little different; it's done in a manhole, but there are still slack loops down there. Pulling an underground lateral into a building can require some fancy digging under the street, sidewalks, and yards, so it can be very expensive (five figures per site). -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701
