The only free way to desalt water is to evaporate it (Which, BTW, would probably get rid of the ammonia from urine.) and recondense it.
Not true -- reverse osmosis will remove salt and other impurities from water. In fact, it is used to produce drinking water from sea water in some areas in the Middle East and Africa, as well as by the military.
Is it though? doesn't that mean it has 3 samples per waveform at 14.7Khz? How then can it reproduce a sine wave, square wave or sawtooth wave accurately at that frequency? How can it differentiate between them?
It can't. It doesn't matter, though because nothing else in the recording or playback system can, either.
Square waves and sawtooth waves, like all waveforms, are the sum of a number of sine waves of different amplitudes, phases, and frequencies.
For example, a square wave contains the original frequency (the fundamental), plus all odd multiples of that frequency (the harmonics). For a 14.7Khz square wave, the lowest frequency harmonic present would be three times 14.7Khz, or 38.1Khz. That's above the frequency response of most of the components in the recording and playback systems. The next harmonic is the fifth, at 67.5Khz. Forget about it.
Even if they could reproduce high enough frequencies to represent and reproduce the square wave, you couldn't hear it as a square wave anyway, because the ear hears sound by breaking it down into it's fundamental soundwaves, and you can't hear above 20Khz at the very highest (probably not even). Since you can't hear the harmonics, you can't hear the difference between a square wave and a sine wave at that frequency.
I wonder if we are able to observe this interplanetary tortoise from earth? If it passes the bright side in full moon, we should have quite a clear view of it since it's going so slowly.
I'm curious what make you think it will be going slowly? It will be orbiting the moon at exactly the same speed as any other craft at the same altitude would be orbiting the moon. The type of engine or thrust has nothing at all to do with orbital mechanics.
Can't anyone write anything tech without feeling the need to throw in a highly-charged buzzword?
If you read the chart's creator's web page, he didn't reverse-engineer anything. He created the chart from the published international specification. That's pretty much the opposite of reverse-engineering: engineering. That is, taking a set of specifications and producing a design that meets them.
In case you aren't aware, the temperature in space where the Hubble sits is colder than -200 Celsius.
In case you weren't aware, the temperature in space where the Hubble is not cold, nor is it hot, or even warm. Space is essentially a vacuum, and therefore has no temperature.
The temperature of Hubble is determined soley by how much it aborbs or radiates energy, since it's actually practically perfectly insulated by the vacuum. It has nothing to do with the temperature of its environment.
In fact, the exterior goes from hundreds of degrees below zero, when it's in the shadow of the earth, to hundreds of degrees above zero when it's in the sun. And it spends much more time in the sun.
Who ever started this "space is cold" idea anyway?
Just imagine that you have a fire in your house blocking access to your exit, now you could go for the window... but your window locks do their job quite well.
Wouldn't you just unlock it? You are on the inside, after all.
Probably a heck of a lot safer than breaking it, anyway.
When we were looking for a photographer for our wedding, I was very disappointed in most of the more popular ones we met with. They all wanted to charge way more than it seemed the job was worth, and none were willing to part with the negatives.
I had a darkroom at the time and was very interested in printing some of the photos myself and made it clear that I was willing to pay somewhat "extra" for the privelege, but no one would go for it.
We did eventually find a photographer who worked out perfect. He shot about 15 rolls of 6x6 medium format and three rolls of 35mm (for low-light and candid shots) for about $1000. This included 5x5 inch proofs of every shot in two albums and all the negatives.
He was primarily a commercial photographer, but we were very happy with him. He got some great shots of fine technical quality, and was very unobtrusive.
So, keep looking, and don't be afraid to look outside of photographers who advertise themselves solely for weddings. I think that there is a lot of compulsive buying behaviors associated with weddings and those "wedding" photographers leverage it to their benefit.
When I was eight or nine years old a neighbor gave me a copy of The Invasion of the Moon 1969 by Peter Ryan. I've read it at least a dozen times since then.
It's a paperback, mostly consisting of transcripts of the communications between Mission Control and the Apollo 11 mission, with commentary and explanation interspersed.
Sadly, the book is long out of print, but you can find used copies through the usual sources. I bought one a couple years ago for a friend who read mine and liked it.
The most obvious example? The fact is that there are 13 of them, in widely scattered locations across the globe, and it's not decentralized?
Even more to your point, there are many more than 13 root name servers. There are 13 root name server IP addresses, but some of those belong to many different servers.
For example, the "f" root server is really 22 servers, themselves distributed around the world. Check out ISC F-Root Information.
I don't know how many root servers there really are, though. Anyone?
there's a reason why Solaris still holds more market share in the enterprise than AIX and HPUX combined
Say what you will about research firms, I know, but have you seen the March 2004 Garner report that talks about server operating system futures?
In a March 2004 report, Gartner predicted that, based on current market share trends, the server operating system shakeout would continue and that only three growth operating systems would exist - AIX, Linux and Windows - through 2008 (0.8 probability). Additionally, by year-end 2008, Gartner predicts that AIX will increase market share and approach or pass Solaris as the No. 1 UNIX operating system (0.8 probability).
I work with AIX systems every day and have worked with Solaris plenty, and the reality is that they are pretty much equally capable technically, and IBM's got a better and more stable business plan, and better a hardware technology growth path.
Nor is there module capable of 'grabbing' the telescope, and has no airlock so even if they did they wouldn't be able to leave the module.
I think the module that would be capable of grabbing the telescope is called a 'man'. Not sure what the name is in Russian. I suspect they could also come up with a technology called a 'tether' or maybe a 'bar' that could be used to attach the telescope and the Russian craft together in orbit.
And why would an airlock be necessary? That's not how they did EVA with the Apollo. Just vent the atmosphere in the capsule and open the door.
Maybe this discussion is indicative of the mental problem that got us to where we are with the shuttle?
Read the article. The cancelled mission was not just to service the telescope in terms of maintenance, it was also to install new instruments worth $167 million as an upgrade.
If they can upgrade what's already there to new technology, why launch a new one? I'm sure the idea of replacing it completely has been considered and the costs weighed.
This book is irrelevant because anyone sane already knows the futility in trying to do anything non-trivial in sh.
I disagree and refer you to an example of a significant shell application that is complex and useful: Enhanced Network Scanjet 5 (I'm the author).
This is about 2,400 lines of Bourne shell (runs under BSD sh or Bash) that reimplements the HP Network Scanjet 5 functionality, with many improvements, particularly the fact that is is completely standalone.
This application was originally written in about five working days, and I firmly beleive that it would have been just about impossible in that time in any other language but shell. The ease with which other utilities such as Sane and Ghostscript were integrated was a huge feature of sh.
Interpolation in the camera does nothing but burn up space on the flash card three times as fast. It certainly doesn't give 6 megapixel image quality. You'd be better off getting a 2 megapixel camera and doing the interpolation on your computer afterward.
A computer that's 5 or 6 years old and likely has hardware that isn't really up to the job any more. I'm curious, does Windows XP run on a PII?
Yes, Windows XP runs fine on a PII.
I have two machines at home that are both 500Mhz K6-3+, both with Windows XP Pro, and they are completely usable. I even do DV video capture, editing, MPEG compression, and burn DVDs on one of them. It takes almost 30 hours in the background to compress 2 hours of video, but all the interactive stuff is very adequately responsive.
In fact, these machines are noticably more responsive than they were previously under Windows 98SE.
If you don't care if it ever locks again, or especially if you want to make sure it doesn't, all you need to do is this:
Drive a sheetmetal or wood screw firmly into the lock cylinder where the key would insert. Next, pull the screw out using a claw hammer. The lock cylinder will fairly easily pop right out.
No they're not, and no they don't. They are like any other private company out there with an on-site telephone system using Direct-In-Dial. Let me explain how it works... (much more deleted)
That's not exactly how it works. If that is how it works, then Vonage would not have been able to transfer my existing phone number to their service that I'd had with the local monopoly for 16 years before that. Surely it is not magically in some block of numbers they have. Their trunks are clearly integrated in the routing infrastructure of phone numbers in the local office here, however that works, for one number to be able to re rerouted from the incumbent carrier to them.
They clearly are hooked into the infrastructure much more like a phone company than an PBX on DID lines. I don't know all the specifics, but it ain't just DID.
_ is not legal in DNS. Please to read RFC's before posting incorrect information. Legal characters in domain names are letters, digits, and the hyphen.
Did you even read the RFC you referred to (RFC 1035)? The section about character restrictions is talking about hostnames, not any possible DNS record type. That would mean names of A and CNAME records.
Specifically, it says (paraphrasing) that you can name anything whatever you want, but unless you want to experience hardship, you should follow existing conventions for the type of object you are naming. It then cites following RFC 822 for mail domains and the old HOSTS.TXT file for hostnames, which is where the character set restrictions come from.
Specifically, in section 3.1 of the RFC you cited, you will find the following quotation:
Although labels can contain any 8 bit values in octets that make up a label, it is strongly recommended that labels follow the preferred syntax described elsewhere in this memo, which is compatible with existing host naming conventions.
How much clearer could they have been that any character is acceptable? They only recommend that existing standards be followed for hostnames. It's not just that "underscores are now okay" as the article says. They were always okay for purposes other than host names.
Later RFCs frequently supercede or clarify earlier ones. Just because you read something once in an RFC and think you understood it correctly, doesn't mean that you are right. In this case, you are wrong. Did you realize the RFC you cited is 16 years old? Did you read or search for any newer ones before you posted?
"Please to [sic] read RFC's before posting incorrect information."
It used to be, though, that "_" was not legal in hostnames. Since these are not hostnames that are being put into DNS, this is a valid usage.
However, it's still a bad idea as some name resolver libraries and other software do assume, through misunderstanding, that "_" is not legal in DNS and fail responses that contain it.
The fault here is with the resolvers, not this scheme, but since the underscores don't add value here, why not make things more compatible with existing broken implementations and just not use underscores?
Myself, I am not wild about the loose use of the TXT resource record type.
Dont you think "fucking dumbass" is a little strong a term to use towards someone who is right, especially when you are wrong?
It probably varies by state, but here in Connecticut at least, utilies absolutely report credit data. In fact, the following text is verbatim from my gas bill (Yankeegas):
As authorized by law, for residential accounts, we supply payment information to credit rating agencies. If your account is more than sixty days delinquent, the delinquency report could harm your credit rating
I will, however, concede your expertise in the area of hookers and dealers.
I FINALLY had to hire an attorney for $1500 to write a poisonous note to them telling them if they ever called again, they would be sued into the ground. $1500 and all this guy did was write a note. After paying him for his services, he never even had to call. Apparently these snakes are so bad that he had a note already written to them and addressed to as many of their staff and even a few home addresses to make certain that they got the clue.
Offtopic to the conversation as a whole perhaps, but to the point of this comment:
There are a damn lot of lawyers out there and a lot of them are actually fine, helpful people. But you need to shop around.
Any decent lawyer will give you a free consultation at which they can tell you if they can help you or not and give you a very good idea of the cost. Especially for something as simple as this. If any lawyer won't do this, skip them and call the next number. If you don't think the price sounds fair, talk to a different lawyer.
Granted, lawyers are highly trained professionals and you should expect to pay at least $125 an hour for real work, but there's no way you should have to pay $1500 for sending a letter.
They're not all snakes. But I agree this guy was. He should have done this for a couple hundred dollars at most. For some reason, though, people seem afraid to shop around for things like this.
VeriSign handles second-level domains. You would ask VeriSign for the nameserver for whatever.com, then ask that server for www.whatever.com. The only way Verizon could do what they claim would be by falsely claiming that whatever.com exists.
That's not true because that's not how DNS works. The full question is always asked of the name server and it returns the best answer it can, which may be a referral to a better server. The root servers indeed would receive a query for 'www.whatever.com' to which they would answer "I don't know, go ask these servers" and return the servers for 'whatever.com', which the client would then ask the same question of.
The root servers could just as easily return an answer instead of the referral.
There is no special-case logic in name resolvers for 'levels' of domain names. They just send the full query to the best-maching server they already know, based on cached and hint data. It's really a brilliantly simple scheme.
