Each time they were disconnected, their lawyer called in 30 minutes or so of opening hours threatening action for breach of contract.

    I believe they were disconnected for good after the rest of the system covering a good portion of the state had been severely crippled for about a month. The ISP had to countersue to get them out of the ISP's collective hair. I don't know if they ever admitted their machine was at fault, or fixed it.

    I'm no grammar expert, but I'd like to point out that some people miss 1 or 2 of the commas in the 2nd Amendment. From the Library of Congress version, there are 3 commas. "A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed." This sentence has 4 phrases. Not one of these phrases alone is a clause and cannot stand independently; no phrase has the proper subject-verb relationship to convey a complete thought. The phrase "being necessary to the security of a free state" is a present participle; it acts as an adjective modifying the noun "[a well regulated] militia." It contains neither the subject nor verb of the sentence. Taken together, "a well regulated militia, being necessary to the security of a free state," is an absolute phrase; absolute phrases do not modify any specific word in a sentence, but rather modify the entire sentence by providing context. "The right of the people to keep and bear arms" is the subject phrase of the sentence. The subject is "the right." "Of the people" and "to keep and bear arms" are prepositional phrases modifying "the right." "Shall not be infringed" is the verb phrase of the sentence. "Shall not be" is an auxiliary verb string modifying the main verb "infringed."

    Therefore, the main idea conveyed by this sentence is "the right shall not be infringed."


    That is so clearly, concisely written that I cannot do the quote without doing the whole thing, all I can add is:

    Hear! Hear! This was written back when people actually studied how the language worked, and those comma's are NOT mistakes, but inserted to make it damned clear to any wannabee tinpot dictators that this is how it works.

    All these newbies that have no concept of how our chosen language is constructed, and therefore choose to interpret it in their own limited tunnel vision view of how things ought to be, often based on their own personal agenda, had best go back to school and actually STUDY the language.

In 100 years, tv as we know it will all be either satellite for the rural areas, or fiber for the municipalities.

That stuff is far less powerfull than the 100kw erp tv transmitters being relegated to the scrap heaps of time.

But strangely, no one is taking into account the rate of defaults for those that have won previous auctions when the business model that made them submit the winning bid cannot be converted into either a service to sell in the time frame the VC people will tolerate, or simply falls on its face in the marketplace. The last figures on the default rate I saw were above 90%, so there will be a rather large 'shakeout' that will take decades to settle.

From that viewpoint, even a source of white noise that cannot be explained would be a candidate for further study.

    I know, I've suffered from the not enough coffee myself for quite a few years, the green tea I use for that just doesn't have the kick in terms of the caffiene content that a good cuppa joe has.

    But that good cuppa joe had taken to keeping me up all night, instead of just half the night, hence the switch. The accumulated years tend to do that, and not much I can do about those, they just keep adding up.

    I suspect I'm probably old enough to be your grandfather too, at 68. Hence the years to have learned as much about ballistics, both internal and external as I have. Thats been one of my hobbies while making a living in electronics for the last 55 years, the last 39 in broadcasting.

    I'm the guy yhou never see, but who makes it all work when again after somebody else has let the smoke out or broken the mirrors, both of which is required to make it all work.

    Guns don't use iron bullets. They use softer metals like copper, lead, uranium...

    Except that this method requires an iron bullet due to its use of strong magnetic fields to move it, not the normal high pressure of burning gunpowder. You should have read the parent article, which tries to explain that, albeit not terribly well in laymans terms.

    A normal guilding metal clad lead cored bullet would in this case, not do much except heat the bullet due to eddy current losses. Possibly enough to melt the lead, and certainly enough to cause heat damage in the surrounding parts of this type of gun.

    Also, depleted uranium isn't terribly soft and usualy is equipt with both a base banding of some softer metal in order to properly engage the barrels rifling as its sized a few thou smaller than the barrel, and a forward band to help guide it. Its main claim to fame is that its heavier than lead by quite a bit. So its harder to launch it, requiring carefully profiled burn rates in order to maximize the total push without causing excessive barrel erosion from the hot gases, always a problem in larger cannon as it can litterally change the barrels perfomance on a shot to shot basis.

    By the same token, holds up its velocity better than lead, making it capable of penetrating the average tanks armour plate where a steel cored 'AP' bullet would knock out a good sized cookie of armour and bounce back at the source of the shot even if the impact is at an angle, making the richochet dangerous to the shooter. We're talkng about springback in the struck surface, which will always bounce back on the same path as the incoming one. Mirror type analogs aren't valid here where the surfaces lock together for a few microseconds...

    If you can penetrate, then no richochet to worry about, except inside the tank, which is where you want it to do maximum damage anyway :)
