Except the only thing that interferes with is your ground troops. A GPS guided bomb can easily have it's antena situated to block ground signals. Even at the height they are dropped this would not significantly reduce the GPS satelite recept (assuming 90 degrees.
A quick redesign should minimize that risk.
Jammers also have to jam 2 frequencies, both civilian and military. If either of them work the results can be accurate enough for military operations.
(There is an advantage to turning off civilian signals in the area, but in the past during conflicts the signals were upgraded, not degraded because the U.S. military used civilian receivers in many instances.)
According to various reports (scientific papers, etc. not stories) it is quite possible to recover multiple generations of data from harddrives.
Thats right, your 20gig drive can contain about 60gigs worth of data. Of course, it would probably take 8 months to recover it all, and a couple hundred thousand dollars... but, theoretically it is possible.
(I'm pretty sure my credit limit isn't woth a few hundred thousand dollars to recover:)
I remember reading an article about a year ago where-in the USB based ethernet/modem for a sat system as actually an ETHERNET device, with a USB to Ethernet adapter built in.
pop the cover and have a look...if you don't mind voiding the warranty.
See, from my perspective thats BULLSHIT, since, the tower I have a problem with could EASILY have been located much closer to a populated area.
Instead, it is in a perfect location to draw a nice large coverage area on a map, but not actually provide service.
(I am aware of the problems and issues as you describe them and know they are real, in this particular instance that I mention that was NOT the reason for the decision.)
but you see, thats entirely my point. The problem isn't analog or digital, it's the damn cellular companies and their stupidity with antenna placement. (especially in the problem I have at the client I mentioned. The ground is FLAT, it's a small town, but the largest in the area, and instead of putting the tower close to town they put it too far away. It made their coverage map look good though.
I've had a Digital phone for several years. The first would switch between digital and analog, the second is GSM, so digital only.
You know what? It rocks. I've never had significant issues with it except at a client site that is not served well. (The 'local' tower is not local and the buildings in the town where the client resides are sufficient to block the signal entirly. This was a screwup on the part of the cellular company.
Anybody that bitches about the sound quality on digital should either find a new provider, or get their hearing checked. I've never had to yell into my phone, and, with the odd bit of noise I've only occasionaly had to ask people to repeat themselves. (and that is because I wasn't paying attention:)
I was using a TDMA Startac, but have since switched to a Nokia 8390 GSM phone. Works great and the coverage is similar or identical to my TDMA. I also notice that less people yell into their phones these days...
Jitter is the shift in frequencies caused by the difference in timing between multiple samples not being consistant, or (this is a stretch, needs a diff. name) the frequency being accurate to itself, but different than intended. (44.5 instead of 44.1, etc.)
While coax or fiber may make a difference on some systems as the the EXACT delay introduced into the signal before being converted to analog, and could, in a complex setup with multple systems handling the signal (in parallel, not sequential) cause unintended distortions. (2 independant amps introducing different delays driving front, and rear speakers in, say, a THEATER....)
There is no real reason to believe jitter will be introduced differently by the two in even a half decent system. (Any system which would convert the sample as a whole, and not per bit would NOT be effected.)
ding. wrong, it IS digital, but at the frwuqnecies used for Ethernet, and, at the LENGTHS used for ethernet there are issues. (Never mind that high frequency binary on a wire starts to act more analog than digital in some ways...)
Typical cable for a stereo system (DVD to stereo, etc) is what, 6ft? You could probably point the 2 systems at each other and use the fiber port without a fiber cable and get a good response....
6ft is nothing, and unless the singal is seriously distorted there will be no data loss or corruption. As for jitter... unless your amplifier has no internal processor doing anything to the sound the jitter is irrelevent as the signal is re-encoded before becoming analog anyway. (my system, admittedly low end has an internal DSP to add various effects. Nothing is immediatly turned to analog from digital, it all goes through a processor first. hence, jitter in isn't the same as the jitter out. (Assuming the internal clock -is- skewed and it results in jitter before the singal is converted to analog the only jitter introduced is from the internal clock, there is no cummulative effect caused by the incoming signal and the outgoing.
Amusingly enough I think DVD players are the absolute exception to th whole debate.
There isn't a huge difference between a $100C (75us?) DVD player and a $200C DVD player. The only feature I bought SPECIFICLY in my last DVD purchase was component outputs. If it weren't for that I would not have replaced my DVD player. (The one I had worked fine, I gave it to my parents, it cost about $200C when I bought it. Worked BETTER than any of the $400+ ones I had seen and used at the same time.
Get an mpeg encoder card (of decent quality) and then compare.
I bought a Tivo and am in the middle of hacking the thing so I can use it in Canada.
It's worth the effort instead of trying to toss a system together to do the same thing. The tivo makes it 'slick'. (All I need to do now is get guide data into the unit for my area, and I'm working on that as we speak.).
ReplayTV, Tivo, etc all BLOW AWAY videocard input as the only way to get anything decent is to either dedicate a fast processor (500Mhz or better) or get a hardware mpeg encoder.
Me, I'll take a unit like a Tivo. (The series2 units, as difficult as they are to hack are slick. USB 2.0 on most of them (the first units had usb 1.x) and they support USB ethernet devices so hooking them to your LAN is easy enough. (You can configure it to get updates/guide data over the net WITHOUT hacking the units.).
Only if you want to abuse it like I do is the Series2 a problem (it is locked down quite tight so you can't run your own code...) I've had an ATI all-in-wonder card, as well as VIVO on my Nvidia card (which I use to watch tv when I play on the computer) and they do not compare to what Tivo can do and does.
oh come now, of course it sounds better with the higher quality cable, I mean, the bits are more easily recognized, they have less distortion and the processor can determine weather it is a bit or not more accuratly and in precise time...
me, I bought the $15 cable. (Somebody somewhere is going to have to spend a week with me and explain why you have to worry about jitter in any piece of equipment *EXCEPT* the last one.
And even then I have my doubts, but atleast it is possible to measure jitter.
I'm no audiophile. I think the long protracted discussions about cables, wiring and shit are a joke. (And convincing me to spend $40 on a OPTICAL cable to run 6ft ain't going to happen, I'll take the $15 cable. ($15C)
But even *I* think 128k MP3s really aren't that great when compared to the original music.
The problem is, being a hit, of any kind, is irrelevent.
It has to be a major hit with a SPECIFIC target group that actually spends money.
Oh, and if it is the wrong target group (even if they spend money) they will still junk it and try something new.
This is why fox hit it big, and now mostly sucks. They spent a lot of money with shows that 'might' be hits. Most of them bombed, but a few hit with an audience and bingo. You had Married with Children, Simpsons, etc.
But, now they go for target markets like everybody else.
Wish I knew what market I was in (of any channel) cuz damnit, I don't seem to get the channel.
If the spam is fraudulent then they likely cannot claim Copyright even if they wanted to.
And if they wanted to they would be rather stupidas you would have sufficient information to have them charged.
If it is NOT fraudulent, or you have no reason to believe it is then yes, Advertising copy is copyrighted like anything else, automatically and all rules apply.
Rule #1. It's Business. Rule #2. Pay me. Rule #3. It was never personal.
While I freely admit I don't run my life off these rules I do repeatedly remind myself of them anyway.
I've helped a previous employer out a couple weeks after I was laid off. The prior-president of the company had moved to another city and in doing so his HD failed. I helped him install windows over the phone. Probably cost me a couple of dollars in longdistance.
On the other hand, 6-8 months after working for my new company I received a call and was asked if I could do some work for them through the company I was working for now. (The first was a distribution company, the second a consulting company). So, the company I worked for got the work, and I got paid to help a previous employer.
A couple years later the guy who was running the IT department after I left had lost his job and moved to another company, he gave my name to a consultant looking for a new employee to pickup some extra work he had available. I got the job and have been happier working for this company than previous. (amusingly doing pretty much the same work, but thats another story).
Did it help being a nice guy? Sure. Did it make up for the couple of dollars I spent on a long distance call, sure.
Would it have paid to be a really nice guy and do the work for them on the side when I was working for the consulting company... no. could have cost me my job and would not have been worth the pay.
If a previous employer calls you up and wants you to do some work for them do it, and charge them consulting rates to do it. If they won't pay then they don't actually want you to help them.
If they are only offering it to you because it would cost them less (and not because you can do it in less time because you know the system) then don't take it. It probably isn't in your interest. (10% less is one thing... 75% less is another...)
If you honestly believe your employer is a threat to your cause you cannot work on other, on going Open Source projects. You would contaminate the project and would potentially expose it to legal liability.
I doubt too many projects would survive such an effect. (It could be illegal to distribute the source code, etc...).
If you really want to do some programming outside of work stick to your own stuff. Open source it if you wish and realize that the project could be killed by/for legal reasons.
Sure signals would leak from floor to floor, but floors are made of more significant material thanmost walls in buildings as well. Which means then atenuate the signal more. So, inherently less interference from the floors below (assuming all else is equal... it isn't...)
According to one article I read on the antenas used for a particular access point it mostly radiated on the plane. Meaning there would be less signal from above or below, combined with the added issue of a floor/ceiling between them and your almost home free...
Buying a product in the U.S. and importing it to Canada is perfectly legal.
Hell, you guys tons of Canadian stuff... (oil & gas, lumber, etc, etc...)
I won't get into the legal issues surrounding satellite reception in Canada with American equipment. I disagree with the current intepretation of the law, but I don't have a directv system and if I did I wouldn't have a problem using the Tivo, it would just 'work'. (it would get the APG guide data and it would call (a local number) to confirm the subscription to tivo.
(Yes, the unit calls a local number, it seems they don't filter out area codes they don't support. I was amused. )
I could careless about it phoning home. I want to damn thing to function fully.
I can afford the subscription. I'd just like it to have my guide data.
I knew this was going to be difficult and time consuming, but when I go looking for information required for me to get the unit to WORK, and not bypass Tivo's subscription model and get hassled about it because people think I'm trying to rip Tivo off.
As it stands I've grabbed a couple of scripts from the Australian website which someone mentioned, I will peruse the scripts and see if they are taking a vastly different approach than I have already started. I doubt they are, a quick glance tells me I'm headed in the right direction. (and my unit may not match up perfectly with the existing scripts as it is a series2 and the scripts are more likely for the original series.)
(it would have been under my account, but it was on a 3rd party computer when I submitted it...) anyways...
I've checked all the forums, so far this is the best response I've gotten.
Which amounts to not much.
The hacking information from the Tivo community is helpfull, but the fact is that the subscription data I wish to get into the unit CANNOT BE PURCHASED FROM TIVO.
And, with a series2 unit you have to be subscribed to use it anyway. (I believe that is coded seperate from the subscription guide data now too.).
I want to use the Tivo in Canada and it is not supported here yet. The DirecTV Tivo units get the data via APG and they still require a dial-out every 28 days to verify subscription status. Putting guide data into a series2 does not bypass this.
For now, I can tweak an existing guide to give me some channels (American ones) with valid guide data. I'd like to put more into it and so far I have seen very little good documentation (or clean source) to do so.
