From what I can gather, the 1500 ft spec is related to connection speed. There is a tradeoff between these. ie 1500ft at 1Mbps and 150ft at 11Mbps are achievable with the same hardware. Apple's airport only supports the 11Mbps and thus is limited to 150ft. This may change soon as Apple is using Lucent technology in their basestation and a firmware/software upgrade may be all that required.
The Bottom line is Lucent is pushing the edges on this technology and I think they are the company to go with for wireless.
you could buy an apple airport (~$295 US) and a wavelan silver card for your box. You may need a mac to get the basestation configured correctly. The airport uses the IEEE 802.11 standard (actually it uses a Wavelan Silver chipset) and thus is compatible across platforms. It also provides NAT and can share DHCP addresses across a wired network simultaneously if you are interested.
If you have an Airport capable mac kicking around to get it configured it may be an easy solution if you don't have a spare box. Unfortunately the configuration software provided by apple to configure the basestation only runs on the iBooks, new iMacs, powerbooks or G4's.
You could also offer to share your bandwidth with your neighbours to offset your costs.
Interesting concept. I would like to know more about this. Is it controlled by a library card? If so, I assume the situation is that minors will have censoring by default unless their legal guardians sign to change access privileges. Not perfect but not too bad. What software are they using? Is it commercially available?
As far as filtering is concerned, instead of blocking out web sites we should create a database of safe sites and sites which are considered very safe (allow all links from those sites, one hop). If appropriately managed, a service like this would quickly blossom into a database containing most of the good info sites on the web. Of course slashdot will have to do something about the trolls before being considered acceptable;-)
I agree with you about the extremes of opinion, people are so polarized on this issue that it is beginning to rival the abortion debate.
Personally I think it's natural for young kids to investigate sexual topics as soon as they are interested (~9 years old??). I would have no problem with my 9 year old boy looking at a Playboy but I wouldn't want him picking up a fisting obsession (or worse) and you guys out there ALL know how easy it is to find this stuff accidentally even if you just surfing for information related to sex.
Given how farfetched physicists are willing to go these days to explain what they can't observe (dark matter), why don't they propose the existance of God to explain the dark matter.
1. Assume that god is omnipotent and everywhere simultaneously
2. Assume that omnipotence correlates with energy
3. E=mc^2
4. God has direct interaction with 1/1^7 individuls per year.
5. God is an individual (can be considered as a quanta)
6. God does not emit electromagnetic radiation
Therefore god is WIMP-Weakly Interacting Massive Particle.
Bill says a flip comment off the mic and this creates a media firestorm suggesting Microsoft is willing to open source Windows.....ahhh allow competitors to view their source code. The company realizes this could be used in their favour as the latter is already standard practice so they vehemently deny any such statement hoping that the government prosecutors will see this ass an easy way out. Rather than break up windows we will force them to allow competitors to view their source code.
Even assuming that everyone is considered a competitor. This would not be a huge benefit to the industry. Microsoft would continue to dominate with perhaps better third party compatibility...furthering their stranglehold on the industry. Even if they posted their source code for Win2k for all to read it would only help them!!!
I don't see any solution to microsoft dominance in the short term. Perhaps Linux in the long term.
In highly experimental areas like gene therapy which are also politically experimental, the reporting requirements are very strict. They want you to report any suspiscious event as an adverse reaction immediately.
As we've seen, the trials can be halted at a moments notice based on an adverse effect thus the Doctors are a little slow to report an effect before they have a better understanding of it. The politically charged atmosphere leads to extremes of opinion on both sides and thus extreme interpretations of results. What may be considered minor to a gene therapy pundit is absolute proof the entire thing should be stopped by the anti-gene therapy advocate. Leaking of information to the press can kill a trial even if there is no validity to the leak. We need a situation where the Doctors can confortably report all events (adverse, unrelated, unknown, and positive) without fear of immature press leaks and with the publics confidence that the trial is being reviewed properly and safely.
If the trial subjects are going to die from their disease with or without treatment, then when one dies during treatment is it necessary to halt all trials?? Probably not. If the patient died due to the treatment, should that treatment be stopped? Yes, at least until they know why the patient died and can find a safe (risk balanced) way of doing it.
We probably need more onsite FDA review during trials to keep everyone honest yet with a high level of confidentiality to prevent hysteria due to sensational news stories.
I completely agree, I recently directed a scientist friend of mine to/. to see an article that was related to her work. I felt I had to warn her about what to expect so that she wouldn't be immediately turned off by what she saw. I'm sure she waded through countless naked and petrified trolls to find the interesting posts (I forgot she would get oldest first by default).
This also has relevence in regards to attracting female readers/posters to/. and linux/OSS in general. How many women viewing/. for the first time would get past a page or two of reading if they hadn't been convinced by someone they know that it would be worth it? How many women will feel like joining a community that has a significant faction that is openly hostile and abusive toward them??
Something definitely has to be done.
I like the idea of the time delay between posts (10 minutes?) to any given story. If this was combined with some andover/VA paid troll killers who's job it was to remove sexually offensive trolls and regular user moderation for positive moderation we might have a solution that works without forcing someone with moderator status to waste their points killing trolls yet allowing serious posters the opportunity to post as fast as it takes to make a serious post.
I see no reason for the impossibility of creatures whose bodies need no sleep.
Sharks don't sleep. They need to keep moving 24/7 to push water across their gills to keep breathing. As far as higher organisms I don't know. Does anyone know if dolphins sleep?
At approximately 7pm 2/7/00 US central time, the internet attained consiousness. The nascent lifeform first went to Yahoo to learn as much as it could about its parent human lifeforms. After discovering that random internet searching led it to pOrn in 90.283% of cases, the fledgling intellect decided to glean the history of earth from book abstracts and reviews at amazon.com. Currently the mass of rogue packets is setting up a media blitz to disguise itself as a coordinated DOS attack to facilitate knowlege growth before the humans decide to shut down the net and kill it.
Estimated equivalent human intelligence as of 11pm US CT is 13 years............just wait a few more hours for the fun to begin.
I don't know whats really happening here but last night from about 8pm CT to 2am CT I could not access Slashdot. I thought someone was DOSing Slashdot and when I finally got through at around 2am I was surprised not to see hundreds of comments about it. At the same time I was able to connect to all the other sights I tried. I assume that something between me (Wisconsin) and Slashdot (Michigan?) was not routing properly. Not being a network guru I just let it go. Then today there seems to be a roving hoard of packets reaking havoc around the web with people claiming that every site they can't connect to is being DOSed.
Perhaps the net has just attained conciousness and has reached the human age equivalent of three!
In the year 2000 the russians saved all the internet traffic into databases. They soon find they can't keep up with the analysis and just dump the project. In 2100 a russian historian stumbles across the discarded tape and finds a way to hack a tape player to read it. S/he has a perfect snapshot of russian society circa the new milennium. Hopefully the historian has methods to extract the useful data from all the packets.
I think you are right..that it did expose a pre-existing problem. Who knows, perhaps these people would have ultimately freaked out in a grocery store never to be the same again or possibly they would have remained 'normal' for the rest of their lives. The bottom line is that LSD can be a dangerous for some people to take and it's not easy to tell (from knowing those people before and after) who's at risk before they try it.
If you are someone who is comfortable with who you are, chances are you will find tripping to be an interesting experience which you find to be mind expanding since it gives you the chance to see things from a completely different viewpoint.
That said, I don't know any of my tripping friends (those who took a lot of it ie>100 trips) who have not been permanently affected by it. Many are still cool, smart and productive people (some possibly better off) but some others are a little bit too 'out there' for my comfort.
Regarding the absence of documented medical evidence about acid induced psychoses, If there isn't much documented evidence it's because the patients we are dealing with are insane and thus unable to give evidence. Unless their friends are willing to admit they were doing ILLEGAL drugs there will be no official record. Also given that mental illness is one of the most stigmatized things in western society today these things are generally swept under the rug. I'd love to see the results of a double blind clinical trial with thousands of participants and see how frequent this actually occurs. Actually, check out http://www.vh.org/Providers/Conferences/CPS/28.htm l . I just did a google search on LSD psychosis and got a lot of hits.The one refernced above suggests that it not due to a predisposition...I must read more.
Its good to see this thread of discussion on this topic. My message to the younger folk reading this...LSD is not worth it. If you feel compelled to try it make sure you are with GOOD friends and brace yourself for what may come.
I have a tested (multi-tested) IQ of 180+. Gee, does that put me in your "super intelligent" category? I've had at one time, 16 hits of acid. It profoundly altered me at the time of taking, and never since touched me......... Face it, you know weak people. Worthless garbage of humanity, who had no business messing with this kind of drug.....So, a "Volkswageon" is a brillant car? It's the car for the "masses" dipshit! Garcia was right, don't do it! You're too stupid a fuck to understand what you would go through..
Mabey you are one of the victims, the way you have reacted so strongly to this post tells me that you are not emotionally sturdy. You react almost as if I am "out to get you"..a well known symptom of people with acid induced psychosis.
Smart people don't quote their IQ's because they know that standard intelligence tests carry little meaning but this is offtopic.
To the other poster who replied stating that Feyman advocated drug use. Feynman said that he never had or would take a psychedelic drug because he valued his ability to think too much to mess with it. Pot and alcohol were acceptable to him
I agree with what you say about alcohol but regarding psychedelics read 'the electric coolaid acid test'
Some people, (usually extremely inteligent people) react badly to LSD and never recover. They spend the rest of their days in an acid induced psychosis. There is no way to tell if you are one of these people until you take the drug. I personally know about 4 such individuals. They all were super intelligent, lively, nice, nerdy types who made the mistake of trying a little mind expaning LSD. Its a true tradegdy for the few innocents who this happens to
As Jerry Garcia said "acid is not for people with volkswagen minds"
Ah, but doesn't it take time to produce all that RNA? They have to be encoded with specific patterns for each problem. And they can only be used once, and then you need a fresh batch.
No it doesnt take much time. It takes about 30 minutes per cycle to add a new base on a dna strand in a commercial DNA synthesizer. Add equal amounts of the four possible bases each round of the synthesis and you can make 4^n sequences in n*30 minutes. ie overnight you can make 10^15 DNA sequences. You then use the parallel nature of enzymatic solution phase reactions to convert all of those into RNA sequences (~1 hour)

From what I could gather, IBM added another atom into the middle of their quantum corral (published circa 1993 or so). The quantum corral is a ring of 30 or so cobalt atoms on a surface that can collectively herd electrons much like an outdoor circular swiming pool herds water. In this new development they noticed that if they add an atom a little off-center in this pool then the waves create a mirror node in the pool symmetrically with respect to the atom. Much like putting a sound post in a musical instrument or a fat guy in your pool. Now the wave patterns are influenced by the presence of the object disrupring your perfect circular corral.
Here's the big development.........

Do you need 1 card and a port? How much is that?
Im not sure how much their access points are but I got an Apple Airport (uses wavelan silver technology) for $299. It has ethernet and phone jacks and serves as a simple router with NAT and port mapping
Can you get by with 2 pc cards, 1 in a non-mobile laptop attached to a ground line?
Yes but not properly on Apples yet, Apple claims they will soon release an airport software base station. I guess they are waiting for people to buy up all the airports before they release the software to turn any mobile with a card into a basestation. You can currently do computer to computer with apples now but not with DHCP and NAT. I think the software is avail for wintel and linux to turn any card into a router but I'm not completely sure

There was no mention of PGP or anything else for verification. Faxes are considered legal given the lawmakers assumption that they originated with a phone call that is trackable.
This would be a great development if there is a certified and secure method of factualizing an e-document. A web site that can actually vouch for the authentication of a document and its originator in a reliable way would be very useful. An e-notary republic is needed.
Every home has a full featured PC (running linux) sitting in the basement which is connected to the internet by fiber (insert fast connection). Next to that is a wireless access point broadcasting to the house.
You shut the alarm off and pick up your mobile tablet computer from your bedside table (powered by crusoe or similar). You turn on the coffee maker, select the music for your shower, adjust the house temperature, check the night trading on your stocks and then go for the shower. Dressing ritual complete and having finished breakfast with (insert name other than natalie) you decide you need a little workout to get your blood pumping so you don your guantlets (wireless glove like devices) and use the tablet to start a deathmatch with some crack freak from (insert country) which is displayed on your 12'x8' plasma display TV. After fragging a few asses you videoconference with your boss (he called you, tablet-transfer to plasma screen), start the car with the tablet, take 10 minutes to surf the web while purging your lower GI tract (three flushes-autosensing), kiss your wife and then its off to work where you sit infront of a PC!

~10 internet appliances/PC. The PC handles all the computing intensive stuff and the appliances handle the interface, little more.
As they point out in the article, for this to work they need to recycle the NAD+ (nicotinamide adenine dinucleotide-oxidized form). They say this should be feasible using electricity. Therefore you need to generate the electricity to do this. If that electricity is generated by burning fossil fuels this is a big waste of time as efficiencies will be much less than 100%. In theory you could use solar or wind or hydro generated electricity to convert CO2 into Methanol but then you need some kind of battery in the car/mobile Co2 generating device and we all know about the engineering problems with batteries especially in cars.
In addition they trap the enzymes in some kind of glass matrix which allows small molecules (NADH + CO2) to diffuse in and out yet retains the proteins in the matrix. If this is some kind of flow device and CO2 is being blown in one end then it will drag the NADH/NAD+ through as well, making it very difficult to recycle.
An approach to realistically reduce the levels of CO2 in the atmosphere is to develop catalytic methods to incorporate CO2 into a polymer or other solid that ideally is as useful to people as polyethylene/polypropylene. Recently a group at Cornell led by Jeff Coates generated such a catalytic system but they have yet to find a truly useful polymer.

There was no mention of PGP or anything else for verification. Faxes are considered legal given the lawmakers assumption that they originated with a phone call that is trackable.
This would be a great development if there is a certified and secure method of factualizing an e-document. A web site that can actually vouch for the authentication of a document and its originator in a reliable way would be very useful. An e-notary republic is needed.
A job for the post office?
but I doubt they will replace PC's
one scenario for the future (~2010)
Every home has a full featured PC (running linux) sitting in the basement which is connected to the internet by fiber (insert fast connection). Next to that is a wireless access point broadcasting to the house.
You shut the alarm off and pick up your mobile tablet computer from your bedside table (powered by crusoe or similar). You turn on the coffee maker, select the music for your shower, adjust the house temperature, check the night trading on your stocks and then go for the shower. Dressing ritual complete and having finished breakfast with (insert name other than natalie) you decide you need a little workout to get your blood pumping so you don your guantlets (wireless glove like devices) and use the tablet to start a deathmatch with some crack freak from (insert country) which is displayed on your 12'x8' plasma display TV. After fragging a few asses you videoconference with your boss (he called you, tablet-transfer to plasma screen), start the car with the tablet, take 10 minutes to surf the web while purging your lower GI tract (three flushes-autosensing), kiss your wife and then its off to work where you sit infront of a PC! (insert cool interface)
~10 internet appliances/PC. The PC handles all the computing intensive stuff and the appliances handle the interface, little more.
Other scenarios?
PET- Personal electronic transactor
;-)
This combination of buzzwords correctly foreshadows e-commerce.
They were also smart enough to use the PET acronym in the name as they knew it would ultimately lead to some good PR from the folks at playboy
Even if it was 20 years late
As they point out in the article, for this to work they need to recycle the NAD+ (nicotinamide adenine dinucleotide-oxidized form). They say this should be feasible using electricity. Therefore you need to generate the electricity to do this. If that electricity is generated by burning fossil fuels this is a big waste of time as efficiencies will be much less than 100%. In theory you could use solar or wind or hydro generated electricity to convert CO2 into Methanol but then you need some kind of battery in the car/mobile Co2 generating device and we all know about the engineering problems with batteries especially in cars.
In addition they trap the enzymes in some kind of glass matrix which allows small molecules (NADH + CO2) to diffuse in and out yet retains the proteins in the matrix. If this is some kind of flow device and CO2 is being blown in one end then it will drag the NADH/NAD+ through as well, making it very difficult to recycle.
An approach to realistically reduce the levels of CO2 in the atmosphere is to develop catalytic methods to incorporate CO2 into a polymer or other solid that ideally is as useful to people as polyethylene/polypropylene. Recently a group at Cornell led by Jeff Coates generated such a catalytic system but they have yet to find a truly useful polymer.
Hopefully soon!
