No it wouldn't. A GPS from an light aircraft cannot successfuly navigate a missle 10ft (that's Feet) off the ground, at Mach 0.8. That's how fast and how low a cruise missle cna fly. That's why they're so lethal, you can't see them on Radar, and by the time you have visual its too late.
Also, range is a big issue. Cruise missles have 100s of miles of range. A little DIY might get 100 tops, nothign to worry about.
Or, do it properly and make sure you work on a T&M (Time & Materials) or Cost-Plus contract. Most Federal contracts are, at least in the "big" industries (Defense, aerospace).
Just make sure you have enough cash to float for 30-60 days,as getting money back takes time. Also, keep detailed invoices, and don't mess with the government money. The government tends to take misappropriation of its money seriously, and an failed audit will sink you.

OpenBSD 3.4 Released
·
· Score: 4, Insightful
DO NOT USE OpenBSD ISOs you randomly find on the Internet. During the 3.3 release, many people downloaded ISOS, only to find out that they were trojaned. This is not a safe, nor supported way, of installing OpenBSD.
If you want the CDs so bad, buy them. They're only $40.
Am I wrong in my assumption that the government of the USA exists to serve the public in the public interest? (You know, "Government for the people, of the people, and by the people?" Sure, it's bullshit, but it's bullshit worth striving for.) No, the government of the United States of America exists to serve the interests of itself and the interests of those who run it. BTW, those aren't the people. While a governement, "for the people, by the people" is a noble goal, it isn't what the US government does anymore.
In that case, the government has no right to hide information from the public, except in the interest of public safety. The problem is that the people don't really know what they should know and don't know. They would demand to know everything, even when they don't need to. This also completely ignores the fact that the public tends to gossip, and if somethign important did get out, it would be the end of it.
That's not to say individual people shouldn't be allowed to have access to government information. That's why we have the NSA. They figure out who should have said information, and give them access to it. Its function is largely due to the fact that an individual person can be trusted, but people as a group cannot. Don't press for it. You're really not missing anything important. What the hell are you gonna do if there really was an alien coverup? The vast majority of the public would do _exactly_ nothing, so what they don't know can't really hurt them.
And what is that reason, exactly? That's what the plaintiff is asking here. Can the government continue to offer a legitimate reason for keeping decades-old documents classified? If so, they'll stay classified.
It doesn't matter. By law, if the NSA deems something to be classified, it stays that way. There is nothing the public can do to declassify the documentation.
Yes, documents do have mechanisms to become declassified over time, but they're fairly simple to override. All someone has to say is: keep this locked up, and it'll stay locked up.
The two most likely resasons for this not being released yet are:
It fell through the cracks
Something about this case is important enough for the government to still protect, for one reason or another. In this case, it will never happen.
Sci-Fi is suing the wrong group anyway. Even if the court rules in their favor, NASA can't declassify the documents. They'd have to sue the department of defense in order to have the documents declassified.
Far more importantly, where is his source code for the testing? The data points looked biased enough that I wouldn't trust his results without being able to review his code.
I'm personally glad that ports to things like vaxen and 68k macintoys are dying. Why waste time maintaining code for systems that are the computer equivalent of a beta VCR? It helps ensure your codebase is more portable. By porting to "Dead" architectures (meaning ones that aren't going to change), you have a constant target that allows you to work out bugs in your codebase (possibly for all architectures) and ensure that it works correctly. Furthermore, if someone is really dedicated to an "dead" platform, it may result in faster code overall, as they may start working on optimizing portions of the codebase for increased performance.
But most of them receive some federal funding, so it seems to me that they have some say on what is installed where. Or, they are federally regulated; same thing. Or not. Besides, for the federal government to put those things in, a law would have to be passed first. If they wanted to do it under the table, then neither you and I have any control over it, or would even know about it. In that case, ignorance is bliss.
That is much slower than realtime. At least it involves some lag behind you.Its also a lot cheaper.
Using a high-gain antenna will amplify the received signal. Doing a little processing on the received signal, and amplifying that signal, can result in a useful signal in cases where the ordinarily specified reception equipment would not be adequate.Except that reflected power drops off expoentially as the distance is increased. To get effictive reception at more than a meter, you would need an exposed, visible attenna, and a signifcant increase in power. RFID works just like a radar system, most of the power is absorbed in the refelection.
In addition, using a highly focussed directional antenna can minimize noise and further improve gain. Filtering at both analog and digital levels can be used to further clean the signal. So you want visible radar dishes, hmm? Oh yeah, the public is really not going to wonder whats going on then.
There are many things you can do to improve the quality of your signal which will not be commonly used in commercial RFID applications because they are simply unnecessary, which will be done in order to do both legitimate and illicit tracking of RFID tags. All of which require time, energy, money, a place to set it up outside the public's eye, things that are not simply practical. CCTV cameras work much better for tracking the general public.
It is not necessary to track you over a great distance. All they have to do is put the scanners nearly everywhere. First they'll install them in the doorways of every building the federal government is involved with. That means every train and train station, bus and bus station (bus stop!), gun store, public utility office, government office, garbage dump, freeway emergency phone. Most of those things you list are not managed or handled by the federal government at all.
Then they'll install them everywhere else - payphones, commonly-traversed areas of streets starting with those with the most foot traffic, parking garage (they might have trouble getting a good signal through your car's body, but they can just wait until you get out) and so on. Way too expensive. Tracking you simply by the forms you fill out is cheaper and eaiser.
Let us not forget that with a high gain antenna, and a good amplifier, you can extend your detection range. Differential receivers which take the local environment into account can achieve even more. And finally, directional antennas with only slightly sophisticated optical recognition and tracking systems can aim the antennae (power send, signal receive) at you and scan up and down your body. You clearly have no clue about how this works. Even if the transmitter was made more powerful, it does you no good, because the tag itself isn't powerful enough to send the reply that distance. Remember that radio is a two way street. Just because one end can talk to the other doesn't mean the other end can talk back. And making a self-powered amplifier small enough to talk back that distance would be nearly impossible.
These tags are essentially nothing more than magentically-activated barcode systems, they are just more modern.
Tracking people with "passive" RFID (a misnomer if I ever heard one, you don't just bounce a signal off it, it transmits) is a much more real problem than you think it is
It is passive. Its passive because it doesn't use any power to "transmit its reply". They work by reflecting back the transmitted signal, and modulating it to provide their ID.
Oh yes it is. When I log in a user with bash as shell, you can _feel_ the delay while bash and the dynamic libraries of it are loaded. Yes, even on my Athlon XP. Why? Because my init system loads neither glibc nor bash.
Now I know you're talking out of your ass. bash(1) depends on libc6 (glibc), and ncurses 5. init(8) depends on glibc, so glibc is already loaded when bash starts up. All the kernel has to do is spawn a new data segment for the new process, which takes nearly 0 time.
The only new library it has to load is ncurses, which is small (241k).
The delay you are seeing is more likely PAM running all its login modules and scripts, not bash being loaded.
If you're gonna try to be smart, at least think before you post.
Maybe, we can't be sure what they really are, as they won't tell them. It'd be very strange for a collection agency to act like this. It'd make more sense for them to be telling him everything about him, not asking him for the information.
Note: Verizon cannot block the call because it's not CID available. If it were to show on CID, it could quite probably be blocked at the service level - but it can't.
Just plain wrong. Ever hear about Out-of-Band call notification? Every single call transmitted in the US carries call information with it, outside the carrier, where only the telcos and the government have access to it.
They can block any call you want, you just have to play hardball. Telcos exist to make life impossible.
Not true... in the ia-32 line of processesors you have two sets of registers: One is a 16-bit set, and one is a 32-bit set. The lower-half of the 32 bit register contains the corrosponding 16-bit register. For example, you have EAX and AX. EAX is 32-bits and AX is 16-bits. The lower 16-bits of EAX happen to be register AX. What this means is a 16-bit or 8-bit variable don't automatically become 32 bits when you use them, it just means that a portion of the full register lies dormant and unused. You don't have to push the full register on the stack either (you can push eax, or ax). Now ia-32 is different from most architectures, and I'm sure there are some that don't have anything besides full-length records that do waste memory, sort of.
Either way, with a move to 64-bits, you also end up using more memory too, and having it. While you don't need 2x as much, you do use more, and don't care about the waste. The advantage of doing the wide math is worth it.
I'd be interested to know how many operations on today's computers actually even use up all 32 bits available to them. I'd expect those situations to be rare: Matrix math operations, some addressing.
How about every time you load a memory address or deference a pointer, since in 32-bit protected mode all you use is 32-bit addresses.
And oh, w/64-bit processors come 64-bit pipelines and the ability to use 64-bit instructions and data. The slowdown is nil.
Although wireless networks offer slower bandwidth than their wired counterparts, they do offer one advantage over hard-connected ethernet: they don't suffer from the same saturation problems. While 100 demanding users could quickly saturate a shared 100 MB/S wire, the same users on wireless will not interfere with eachother. Wireless scales much better than you seem to think.
Or not. Remember, the switch or hub is still usually only 11MBs, meaning the max out still occurs. Your network is only as wide as its narrowest portion. And you still need wires to connect them to your routers, servers, and the Internet. Sorry.
Secondly, a couple hunderd extra broadcast packets aren't going to saturate a 100 base-t network. A packet is tiny. If I do a tcpdump right now, you wouldn't believe the number of broadcast packets flying around here at this moment. My network connnection isn't being adversely affected.
That's because your using only TCP/IP, and not doing any sensitive or real-time applications. When a single packet can't be retransmitted or dropped, 100Mb/s is not so big after all. Your average corporate LAN doesn't have these needs, but 100MB/s is still not at lot of bandwidth depending on your needs.
