While Qinetiq has managed two weeks, DARPA is working on a five-year lifespan for its vehicles through the VULTURE program. Additional specs: 450 kg payload, 5kW payload power and flight in the 60k ft region.
Frequency hopping by itself is not secure. It does add value to the system by making it more difficult to intercept and jam communications. By placing the entire output power of the radio into a limited frequency band, you get better range and jamming resistance. By both radios being on the same hopset, the receiving radio already knows where to tune its receiver and seek the new signal. From the linked description, SINCGARS has 2320 channels, so monitoring all of them at a given time becomes difficult. However, SINCGARS is a fairly old technology, so the chipping frequency is low compared to more modern radios.
Things you should note: There is no such thing as a multi-level secure (MLS) operating system (OS) that is in common use. Sun used to be certified, but it was always several years before the OS could be certified and by then the technology had moved on. Note also that there are various ancient versions of the Oracle DB that were certified MLS. No more. They typically run only in a "system high" mode where everything on the net is assumed to be at the same classification level.
The fine folk at NRL are producing something closer to a "High Assurance Guard" between networks of various security levels. An example is Radiant Mercury, which I have been informed is a PITA to use and a constant drain of funds because you have to go back to the vendor every time you need to open it up for an application. It's a very restrictive and expensive tool. Anything that will permit a cheaper, and faster guard will benefit them.
How would you address the critique that you excessively extrapolate from a single data point to a generality?
In particular I refer to a show where you were examining fuel mileage on SUVs with windows open vs. air conditioning. As an engineer, I believe that you failed to conduct adequate experimentation to demonstrate anything other than results at a single data point and you didn't make that clear to your viewers.
They do the same thing at my workplace. And pick out the top ten or so (ab)users each month for a little reality check on what is and is not permissible. And end up firing about one person per month.
Management also supports this because it's really bad when a government agency shows up as being one of the top ten visitors to a porn site. That's the type of thing that can put you on the Base Realignment And Closure (BRAC) hitlist.
You miss my point. You mistake component variety for vendor independence. Just because you are blind to your shackles doesn't mean that they're not present.
Having programmed more architectures than you have fingers, I know full well what the implications of my choices are. And I choose to put my money where my mouth is. I have multiple unix boxen at home for various programming chores and choose a Mac as my primary system. When you understand how powerful a choice that is, perhaps you will have a chance of reaching adulthood.
It's also obvious that you don't know what you're talking about when you speak of Apple. A trip to the Apple Store shows me four laptop lcd display sizes, multiple drive options, multiple memory options and a build-to-order section. Check it out. You might actually learn something today.
You are correct. Being a monopoly is not illegal. They were convicted of illegally maintaining their monopoly. There's a right way and a wrong way. Microsoft exemplifies the latter in its business dealings.
[begin snide commentary] I always make sure that all of the software I purchase is compatible with that of a convicted monopolist! [end snide commentary]
Vendor independence? From whom? Microsoft or Intel? Multiple distribution channels does not correspond to vendor independance.
However, if you want the Quartz graphics and user interface and the various iApps that are provided with the system, you will have to purchase and use their hardware.
In the US, the government is considered "self-insured" and is not permitted to purchase policies from commercial providers. Any adequately large business may do this as well. It comes into play when I'm on travel and not permitted to purchase the various damage waivers on rental cars. The travel office refuses to reimburse them.
IBM/Lotus, in order to be able to export Notes with encryption, inserted a method that separately encrypted 40 odd bits of the key with an IBM-only key. End users had full keys, IBM could recover 40 bits, TLAs sould have to brute-force the rest of the key. An interesting compromise.
IBM had a choice of processors. Morotola's 68000 or Intel's 8088. They were afraid that Motorola couldn't produce the 68k in quantity and therefore chose the 8088. Engineers in IBM acknowledged that the 68k was the better microprocessor, closer to its mainframe architectures, and easier to work with. It was fear of shipping a product without having anything to ship that made them chose the 8088. Intel has been riding the gravy train from that one decision ever since.
1) They stole the _Ground Station_ software.
2) You still need a ground based satellite station to make use of the software.
and I suspect the links up to the satellites are encrypted so:
1) the encryption algorithm is now considered public/compromised (safe assumption)
2) the keys are not compromised
Under standard protocols, the keys would be changed immediately and periodically thereafter (at least monthly). Particularly since the link also distributes the P(Y) weekly and monthly subkeys to the satellites.

Bad science is bad science. And we certainly don't need for a TV show that's purporting to dispell urban legends to display poor technique.

Juniper has a horse in the race, selling network devices.
There's currently an IPv6 conference at which they're appearing as well. The conference ends today (2005-May-26).
There's a Washington Post article on the summit.
I'm posting from the summit, where they have a IPv6 802.11 network up for visitors use.
would highly resent having to replace all it's fine work on NMCI with a new technology. Even if it would be an improvement.
I'll install their client on a Sinclair Z-80 operating over a 110 bps teletype line and make out like a bandit!

> Apple!!!! Bring OSX to X86 and we will make it worth your while!
Apple does provide the core system at http://developer.apple.com/darwin/
However, if you want the Quartz graphics and user interface and the various iApps that are provided with the system, you will have to purchase and use their hardware.
And then $100/hour for "assistance" - it's a better business model than many .coms had.
and $800 for his enemies.
Make them part of the Government IT workforce. Protecting the rest of us from their ever younger brethren...

IBM went looking for an OS afterwards.
