although this bulb is 'twice as efficient' as current LED bulbs, 140 lumens per watt is not far from where LEDs are going to be in the year 2012. Leds are also narrow band light pollution (usually a specific single frequency)
not to mention, you have to buy this bulb every 20,000 hours, compared to a MTBF of 300,000 hours for LEDs. so, by 2012 Everyone is going to want LEDs, especially the super efficient ones, that produce around 130 lumens/watt.
of course, even 70 lumens per watt isn't bad when you consider the 300,000 hour life. Especially since you can throw a well designed led bulb against a wall, without breaking it.
well, the html code is fairly clean, but since it loads a couple swf files, and avi, and numerous websites and irc, as well as im clients, there is the possibility that the swf file or avi are malformed to contain an exploit, or the websites could have exploit code on them, while connecting to im and irc can expose your ip address to hackers, and since aim and irc often have gaping security holes, that could be the vector of attack.
I'm basing this on the guy who pasted the web page code, after a reset.
it would be far more scientific to take a known clean, preferably sp3ed machine make a backup of all files in linux (dual boot with 2 hds or whatever) then diff the results after letting that site run for 1 minute. any exploits would then show up among the files that normally change, the list should be fairly short, and programs and prefetched files etc will be easy to spot.
so now, everyone who's a 'novice' is a child now? does that mean if i google basic wiki articles i'll be getting hasbro ads?
there are a lot of things i have an above average understanding of, but there is no shortage of subjects in which I'm still at a novice level of understanding. google, and wikipedia are the first tools i turn to to find information when I'm lacking... does that mean they'll be skewing ads to think I'm a child?
"Their unique molecular structure results in extraordinary macroscopic properties, including high tensile strength, high electrical conductivity, high ductility, high resistance to heat, and relative chemical inactivity"
carbon fiber is made from graphite and "Graphite is a crystalline material"
Crystals shatter bucky tubes (aka carbon nanotubes) bend before they break
so no they don't shatter, the main problem is producing them, and aligning them to create greater structural strength
As long as we don't use zinc painted shells i think we're set here, except for the parking, such a vehicle it is easier to have several ropes pulled by dozens of men to tie the ship down to moorings rather than to reduce the amount of hydrogen gas stored. so who's going to pay for that valet parking service?
pedantic on: Technically the 'center' of Jupiter is a single point in the very middle of the planet not the 'entire core of Jupiter' so technically storing 'as much hydrogen as the center of Jupiter' is Technically 1 atom of hydrogen, or perhaps a single quark, which may or may not belong to a hydrogen atom, depending on the resolution of your examination of the Exact Center of Jupiter.
Just being pedantic, but the core of Jupiter is Much much larger than the exact center of Jupiter. which is a single reference point, and not a mass of atoms. the article suggested that a buckyball could contain a higher Density of hydrogen, without breaking than the hypothetical density of Jupiter at it's central point (which is where mass is the most compressed)
in no way was the volume of hydrogen in the core of jupiter mentioned, only the density at the 'center point of jupiter'
"for DVDs the keys needed for the decryption process is stored in an area on the disc which is not writable on DVD-Rs."
*cough* bullshit *cough*
DVD mastering involves, shockingly standard DVD recorders and Grade 1 recordable media.
and it's the other way around DVD-Rs contain data that pressed DVDs lack it's called the ATIP groove. which helps recording software burn media at the correct speed.
In countries where marijuana is legal (the Netherlands) people go to stores and buy cultivated marijuana why? People aren't farmers, most city dwellers don't even own arable soil, and marijuana plants while they can be grown indoors, are tall, and processing them is an effort as well. So people pay money, for other people to grow, harvest, prepare, and package the marijuana... it's like saying tobacco is legal so people should grow their own to avoid the high price of taxes... growing tobacco is easy, refining it for smoking IS hard. That's why people pay other people to do it for them, even with absurd $2.50 a pack taxes on them.
the MTBF on a fluorescent light is 2.7 years, although they can last longer if not constantly switched. also they have components to 'jump start' the bulb, fluorescents have a component that creates a large electrical surge to 'switch' the bulb on... LEDS just have vanilla AC/DC inverters and low wattage ones too. yeah cheap companies can produce substandard designs, but all it takes as they say is one major manufacturer to 'target' the 34.2 year MTBF crowd (airlines, major companies like wal-mart etc...) and then Everyone who wants a decent bulb will buy from company A with this awesome 34.2 year MTBF bulb.
Well TFA mentions the mercury problem of compact fluorescents, but CF bulbs have other problems, the first compact fluorescent bulbs were big circles, meant to be able to be installed in Some table lamps... well, table lamps went by the way side, in terms of popularity, and CF bulbs are much much larger than a 'normal' light bulb, and they 'look funny' and to get the same lumens you need a larger bulb, plus CFs are fragile, really bad for parents of small to medium sized kids, or larger less mature models.
http://www.superbrightleds.com/cgi-bin/store/commerce.cgi?product=MR16 if you look at some of the models available online now for LEDs spotlight and normal bulb shapes are the ones currently for sale, although, I'm sure when the inverters get smaller or they become more popular decorator bulb shapes will become reasonable. FREEZER lights are now POSSIBLE LEDS can operate in the temperature range of freezers Easily. In the past, freezers with lights, kept the light somewhere odd, or unusable like in the edge of the lid, or something but LEDS can easily operate in a freezer, as long as the control circuitry is protected from temperature. It has always annoyed me that freezers don't have lights, now there no longer is a reason for this annoyance. YES not as good as the psychedelic rainbow bulb... but more practical.
because of shape and color possibilities LED lights are more practical than CF bulbs, as long as you can make the integrated circuitry small enough any bulb shape is possible instead of being limited to tubes and spirals and circles or very long tubes...
going from 2.7 years (MTBF of fluorescents) to 34.2 years is really not that bad considering some LED bulbs are now as cheap as $8 if they can 'market' CF bulbs as 'seven years' of life then that means they should be able to market 'LED bulbs' as '92.3 years'
Sweet they Even have a RGB 'color changing' bulb, not quite the psychedelic rainbow bulb i imagined but it's getting closer... So close, psychedelic LED lights YES MUST HAVE must own psychedelic light bulb!!!
you know, this subject (1 TB RAM) brings up an annoying point, every year RAM access has gotten slower and slower relative to the CPU. when you bought a 486 computer, the RAM and Processor were running essentially at the same speed if the CPU needed data, as fast as it could be transfered from disc to ram was good enough, the cpu never hit cycles where the ram couldn't keep up with cached data and would miss a cycle for the want of data. But every new system, from the Pentium 1 on up ram has gotten slower and slower than the CPU, so now the CPU comes with 256KB to 8MB of 'very fast ram' that is specially designed to run at the speed of the processor, because the processor needs that cache for when the ram hasn't acquired and written the data to ram from HD because the system memory simply isn't fast enough.
I have a gaming rig I custom built 5 or 6 years ago with some very sweet OCZ ram with 2-2-2-2 timings, but now when i was wish-listing a new gaming PC the best ram i could find was 3-4-4-15 timings that's ALMOST HALF THE SPEED that means that it's going to hit those 'unable to fetch ram for the CPU' TWICE AS OFTEN with horrendous results... And it's getting worse, DDR3 ram is all running at 5-5-5-15 timings stock, and mind you 4-4-4-15 is the normal variety of DDR2 'fast' ram, this was again OCZ over-clocked ram...
with multi-core processors this is only going to get worse, with a dual processor rig, to truly keep both processors from missing cache you realistically need 1-1-1-10 ram and they KEEP MAKING THINGS WORSE by bumping up the amount of 'burst' data the RAM can put out, instead of how FAST the ram can access and reload ram!!!
really with such pathetic timings realistically a dual core is going to be spending about 20% of it's cycles 'waiting on ram' if it needs randomly accessed memory, that can't be 'burst read' a lot of applications need random access, database, server farms, complex 3-d video game graphics... the reason why 512MB graphic cards cost so much is they really all need REALLY FAST random access memory that is way faster than 'stock' DDR3... and the reason why frame rates don't scale with more processor pipelines very well, is because those cards keep missing strokes because the system wasn't able to load the memory in time for the processor to work on it...
I can't think of a single mainstream computers need to 'burst' more GB/second Instead of improving latency, yet the crazy computer scientists keep making it worse by engineering for 'burst' mode rather than latency.
it almost makes one want to use normal DDR 1 ram, with the sweet 2-2-2-2 timings instead of ddr2...
call me crazy but i've always preferred ed. vi is ANNOYING remember how to do everything with keyboard commands?!?!? what am i a nuclear physicist????? i need context sensitive text menus that come up with an on screen displayed keystroke.. i come up with simple text cyphers to encode secure passwords on a plain piece of paper....i don't have spare memory to assign for how to 'use' a program man it's all in use so i can remember what i did today! if I'm lucky jeeze. i constantly look at man pages in a separate terminal every time i need to run a terminal app it's pathetic, but it works, some times i can grep the man page, but that only saves me a little time... if i remember/know what part of the man page i need to see in part...
They could always use aligned carbon nano tubes... supposedly you can get them quite a bit stronger than aluminum for the same weight very spendy, but if the roll bar and side impact beams are carbon nanotube you could make a safe, but light roll cage to protect the occupants, without adding as much weight as steel would use.
but like you said, if it's not in the requirements they probably wont do it. also, carbon nano tubes are hardly mass production techniques, especially since it takes a whole day for 1 factory to produce 1 sheet of non-aligned carbon nano tubes. perhaps nano-production techniques will get better, but right now they're still an early, unproven material.
LEDs are the best and worst thing to happen to the lighting industry.
On the one hand, they're Extremely bright for the electricity consumed, very good, they can come in any wavelength of color, for multicolored lights like Christmas lights, or for 'party bulbs' that with a little circuitry could produce a flashing swirl of rainbow colored light by switching various LEDS off and on... They're very small, and that means you can make any variety of decorator bulb configurations...
that's over 1305% longer than Compact Fluorescent Bulbs... in truth a LED can easily last 500,000 hours of use, the MTBF is just an estimate.... and forget them burning out from being switched on and off, Myth busters tried to do it, they tested every array of lighting combinations, and the LED array was happily blinking away 3 months later, when they finally pulled the plug on trying to get them to burn out from switching them on and off...
So, now what do you do? The government assumes that by 2012 LEDs will use 1/3 the watts per lumen VS Compact fluorescent bulbs... so it's not going to take environmentalists long to promote the usage of LED lighting...
So LEDS are a double edged sword for the lighting industry, on the one hand they're the best of the best for the environment, but on the other hand there is no turnover of bulbs. you'll be giving the LED bulbs to your grandkids before they have to replace them... For instance if you use a light 3 hours a day it will last statistically nearly 274 years. if like wal-mart you run the bulb 24/7/365 the bulbs will last an average of 34.2 years. 34.2 years.... yeah you might forget how to change a light bulb, once you get used to LEDs.
Ironically, the US radium paint was toxic for 2 reasons. 1. radium 2. phosphorus most of the women died from the phosphorus poisoning that degraded away their bones, not from the radium poisoning. and you know what? in france, where radium was discovered, they used 'cotton swabs' to apply the paint rather than horsehair brushes. cotton swabs had no need to be licked (the horsehair brushes had to be licked ever 2-3 strokes)
analysis of public voting machines will turn up ugly bugs like being able to report 100% of the district voting for one candidate, while 67% voted for the other. there are so many things that can go wrong with voting machine software, not to mention a lot of the machines are shipped by companies with strong political ties, who some argue 'rig' the firmwares results for specific elections. the latter is why I'd bet they don't want random voting machine testing. people finding 'bugs' for you will just cost a little programming work to debug it, the only reason i can see for them to sue, is if they really are rigging the elections for a price.
AV probably won't protect you but... I remember a long time ago how apple managed to ship OSX with ALL Kinds of remote unix vulnerabilities that had been patched for YEARS... AV software won't catch any of it though, you need an intrusion detection system.
by now you'd think they'd have patched all those holes, but still running anything remotely related to unix without an intrusion detection system is like going out side, in mid-winter, in Antarctica with no pants on to moon some penguins...
but yeah, anti-virus programs are useless in unix environments, because if they root you you'll never read the viruses files anyways... windows rootkits work the same way if they're programmed right (to claim to the ntfs reader process that real files that load every boot are deleted and so don't show their files in the list even though they're still there..) its a bit easier in unix, because once you've escalated to root, its every other process that has to do your bidding.
use of frell!?! Ah yes, why the Frell do I have to be the one to mention frelling dren!
ah yes, farscape found a loophole in the FCC censorship problem... just make up a word, it's made up after all. and with websites it's easy to link a made up word to a 'real' curse word.
splice in the thc making dna into kenaf and they'll start promoting kenaf too they are after all Related plants... and hemp is widely used already in china, while kenaf is just starting to be really looked at...
it would be more useful to know what effects kenaf has on the hydrosphere, compared to 'trees' and if parts of the kenaf plant can be burned to produce the paper, the way the bark is burned to produce paper from wood..
they say kenaf uses little water, and grows fast, but that doesn't give specifics on long term effects on the hydrosphere of using kenaf instead of trees... many crops ruin the hydrosphere, causing water to run off, and evaporating little rainfall back into the atmosphere..
kenaf looks almost as tall as a sapling tree, so perhaps it's an eco-friendly crop, but it would be better to have hard science than speculation. well it does use 'safer' bleaching agents than wood, and having less potable water, is better than polluted water. very interesting, most paper mills can be converted to kenaf, and makes 'superior news print' because it's whiter than paper, i wonder how well it recycles.. another troubling thing people forget to mention.
ah well, it uses about 1/10th the land paper production needs, and we can always use trees for something else. like bio-renewable energy
LEDs are good for the environment in many ways... for one thing they've been catching on as 'Christmas lights' for decoration use the plus side, they can blink a trillion times and never burn out. the downside, you need more sophisticated controls to make sure people can see the blinking. this will undoubtedly save a lot of 'wasted' resource by allowing Christmas decorations to be used for decades, instead of fiddling with bulbs every year to find the shorted ones, or 'just buying new ones' to avoid that hassle.
If the DOE expects them to provide almost 3x the light per watt vs CFL they really really will be the way to go for most consumer lighting. on the plus side, the little ones can play with the light switch until they have carpel tunnel, and LED bulbs will Never burn out from being switched on and off. Myth busters was unable to design a rig that would cause LEDs to burn out, so you Know they'll be good for the environment.
phase 3 studies are from 300-3000 people (max) I've never read about phase 3 studies so i didn't know, but i Knew they don't go to 'hundreds of thousands' of people
well, from what i read online, a 'small' phase 2 study (50 people) cost about $800,000 to fund (and the person trying to patent it as a 'cancer cure' is doing this, and raised the money over the internet...)
maybe because it's being done in Canada and not the US that laws may be different... but, yeah also, keep in mind 90% of phase 1 studies are rejected by the FDA and those animal studies cost money too, so there IS a lot of money savings by it being an approved drug. You know for instance, a safe dose for humans (it was approved after all) and what possible side effects are etc...
Phase 2 and 3 studies don't 'involve hundreds of thousands of people' so I'm not sure where you're getting your numbers from...the largest study I've personally heard of was 300 people... although yes, with small numbers the fda can deny your application and say you need more people etc...
In practice you'd get sued... ala the Sony Rootkit fiasco... they did it not once but Twice, once with music cds and a second time with move dvds... you think they would have learned that putting a rootkit in your software (with the aim of ratting out 'music/movie pirates') is going to get you sued.
now on the other hand, if you live in china, creating a virus that shuts down a couple million computers, That will get you a job. in IT security... likely with one of the companies that can't remove your virus...
Depending on where you live in the world you Might get away with anti-malware malware, but then those are the kinds of places where they don't ask questions about people with bullets in their heads...

the MTBF on a fluorescent light is 2.7 years, although they can last longer if not constantly switched. also they have components to 'jump start' the bulb, fluorescents have a component that creates a large electrical surge to 'switch' the bulb on...

by now you'd think they'd have patched all those holes, but still running anything remotely related to unix without an intrusion detection system is like going out side, in mid-winter, in Antarctica with no pants on to moon some penguins...
but yeah, anti-virus programs are useless in unix environments, because if they root you you'll never read the viruses files anyways... windows rootkits work the same way if they're programmed right (to claim to the ntfs reader process that real files that load every boot are deleted and so don't show their files in the list even though they're still there..) its a bit easier in unix, because once you've escalated to root, its every other process that has to do your bidding.
use of frell!?! Ah yes, why the Frell do I have to be the one to mention frelling dren!
ah yes, farscape found a loophole in the FCC censorship problem... just make up a word, it's made up after all. and with websites it's easy to link a made up word to a 'real' curse word.
splice in the thc making dna into kenaf and they'll start promoting kenaf too they are after all Related plants... and hemp is widely used already in china, while kenaf is just starting to be really looked at...
it would be more useful to know what effects kenaf has on the hydrosphere, compared to 'trees' and if parts of the kenaf plant can be burned to produce the paper, the way the bark is burned to produce paper from wood..
they say kenaf uses little water, and grows fast, but that doesn't give specifics on long term effects on the hydrosphere of using kenaf instead of trees... many crops ruin the hydrosphere, causing water to run off, and evaporating little rainfall back into the atmosphere..
kenaf looks almost as tall as a sapling tree, so perhaps it's an eco-friendly crop, but it would be better to have hard science than speculation. well it does use 'safer' bleaching agents than wood, and having less potable water, is better than polluted water. very interesting, most paper mills can be converted to kenaf, and makes 'superior news print' because it's whiter than paper, i wonder how well it recycles.. another troubling thing people forget to mention.
ah well, it uses about 1/10th the land paper production needs, and we can always use trees for something else. like bio-renewable energy
LEDs are good for the environment in many ways... for one thing they've been catching on as 'Christmas lights' for decoration use the plus side, they can blink a trillion times and never burn out. the downside, you need more sophisticated controls to make sure people can see the blinking. this will undoubtedly save a lot of 'wasted' resource by allowing Christmas decorations to be used for decades, instead of fiddling with bulbs every year to find the shorted ones, or 'just buying new ones' to avoid that hassle.
If the DOE expects them to provide almost 3x the light per watt vs CFL they really really will be the way to go for most consumer lighting. on the plus side, the little ones can play with the light switch until they have carpel tunnel, and LED bulbs will Never burn out from being switched on and off. Myth busters was unable to design a rig that would cause LEDs to burn out, so you Know they'll be good for the environment.
phase 3 studies are from 300-3000 people (max) I've never read about phase 3 studies so i didn't know, but i Knew they don't go to 'hundreds of thousands' of people
well, from what i read online, a 'small' phase 2 study (50 people) cost about $800,000 to fund (and the person trying to patent it as a 'cancer cure' is doing this, and raised the money over the internet...)
maybe because it's being done in Canada and not the US that laws may be different... but, yeah also, keep in mind 90% of phase 1 studies are rejected by the FDA and those animal studies cost money too, so there IS a lot of money savings by it being an approved drug. You know for instance, a safe dose for humans (it was approved after all) and what possible side effects are etc...
Phase 2 and 3 studies don't 'involve hundreds of thousands of people' so I'm not sure where you're getting your numbers from...the largest study I've personally heard of was 300 people... although yes, with small numbers the fda can deny your application and say you need more people etc...
In practice you'd get sued... ala the Sony Rootkit fiasco... they did it not once but Twice, once with music cds and a second time with move dvds... you think they would have learned that putting a rootkit in your software (with the aim of ratting out 'music/movie pirates') is going to get you sued.
now on the other hand, if you live in china, creating a virus that shuts down a couple million computers, That will get you a job. in IT security... likely with one of the companies that can't remove your virus...
Depending on where you live in the world you Might get away with anti-malware malware, but then those are the kinds of places where they don't ask questions about people with bullets in their heads...
