Douglas Barnes, an Oakland-based hacker and cypherpunk, looked into this issue a couple of years ago when, inspired by Bruce Sterling's Islands in the Net, he was doing background research on a project to set up a data haven in the Caribbean. "I found out that the idea of the Internet as a highly distributed, redundant global communications system is a myth,'' he discovered. "Virtually all communications between countries take place through a very small number of bottlenecks, and the available bandwidth simply isn't that great.'' And he cautions: "Even outfits like FLAG don't really grok the Internet. The undersized cables they are running reflect their myopic outlook.''
So the bad news is that the capacity of modern undersea cables like FLAG isn't very impressive by Internet standards, but the slightly better news is that such cables are much better than what we have now.Here's how they work: Signals are transmitted down the fiber as modulated laser light with a wavelength of 1,558 nanometers (nm), which is in the infrared range. These signals begin to fade after they have traveled a certain distance, so it's necessary to build amplifiers into the cable every so often. In the case of FLAG, the spacing of these amplifiers ranges from 45 to 85 kilometers. They work on a strikingly simple and elegant principle. Each amplifier contains an approximately 10-meter-long piece of special fiber that has been doped with erbium ions, making it capable of functioning as a laser medium. A separate semiconductor laser built into the amplifier generates powerful light at 1,480 nm - close to the same frequency as the signal beam, but not close enough nike free 3.0 v4 shoes
to interfere with it. This light, directed into the doped fiber, pumps the electrons orbiting around those erbium ions up to a higher energy level.
The signal coming down the FLAG cable passes through the doped fiber and causes it to lase, i.e., the excited electrons drop back down to a lower energy level, emitting light that is coherent with the incoming signal - which is to say that it is an exact copy of the incoming signal,nike free 5.0 v3 uk discount
except more powerful.
The amplifiers need power - up to 10,000 volts DC, cheap nike air max
at 0.9 amperes. Since public 10,000-volt outlets are few and far between on the bottom of the ocean, this power must be delivered down the same cable that carries the fibers. The cable, therefore, consists of an inner core of four optical fibers, coated with plastic jackets of different colors so that the people at opposite ends can tell which is which, plus a thin copper wire that is used for test purposes. The total thickness of these elements taken together is comparable to a pencil lead; they are contained within a transparent plastic tube. Surrounding this tube is a sheath consisting of three steel nike air max 2014 uk
segments designed so that they interlock and form a circular jacket. Around that is a layer of about 20 steel "strength wires" - each perhaps 2 mm in diameter - that wrap around the core in a steep helix. Around the strength wires goes a copper tube that serves as the conductor for the 10,000-volt power feed. Only one conductor is needed because the ocean serves as the ground wire. This tube also is watertight and so performs the additional function of protecting the cable's innards. It then is surrounded by polyethylene insulation to a total thickness of about an inch. To protect it from the rigors of shipment and laying, the nike air max 90 hyperfuse mens
entire cable is clothed in good old-fashioned tarred jute, although jute nowadays is made from plastic, not hemp.
This more nike blazer shoes
or less describes how all submarine cables are being made as of 1996. Only a few companies in the world know how to make cables like this: AT&T Submarine Systems International (AT&T-SSI) in the US, Alcatel in France, and KDD Submarine Cable Systems (KDD-SCS) in Japan, among others. AT&T-SSI and KDD-SCS frequently work together on large projects and are responsible for FLAG. Alcatel, in classic French fasion, likes to go it alone.
This basic technology will, by the end of the century, be carrying most of the information between continents. Copper-based coaxial cable systems are still in operation in many places around the world, but all of them will have reached the end of their practical lifetimes within a few years. Even if they still function, they are not worth the trouble it takes to operate them. TPC-1 (Trans Pacific Cable #1), which connected Japan to Guam and hence to the United States in 1964, is still in perfect working order, but so commercially worthless that it has been turned over to a team at Tokyo University, which is using it to carry out seismic research. The capacity of such cables is so tiny that modern fiber cables could absorb all of their traffic with barely a hiccup if the right switches and routers were in place. Likewise, satellites have failed to match some of the latest leaps in fiber capacity and can no longer compete with submarine cables, at least until such time as nike blazer high mens uk
low-flying constellations such as Iridium and Teledesic begin operating.

Within the next few years, several huge third-generational optical fiber systems will be coming online: not only FLAG but a FLAG competitor called SEA-ME-WE 3 (Southeast Asia-Middle East-Western Europe #3); TPC-5 (Trans-Pacific Cable #5); APCN (Asia-Pacific Cable Network), which is a web of cables interconnecting Japan, Korea, Hong Kong, Taiwan, Malaysia, Thailand, Indonesia, Singapore, Australia, and the Philippines; and the latest TAT (Transatlantic) cable. So FLAG is part of a trend that will soon bring about a vast increase in intercontinental bandwidth.
Large portions of this section cheap nike free run shoes
were written in a hotel in Ban Hat Yai, Thailand, which is one of the information-transfer capitals of the planet regardless of whether you think of information transfer as bits propagating down an optical fiber, profound and complex religious faiths being transmitted down through countless generations, or genetic material being interchanged between consenting adults. Male travelers approaching Ban Hat Yai will have a difficult time convincing travel agents, railway conductors, and taxi drivers that they are coming only to look at a big fat wire, but the hacker tourist must get used to being misunderstood.
We stayed in a hotel with all the glossy accoutrements of an Asian business center plus a few perks such as partially used jumbo condom packages squirreled away on closet shelves, disconcertingly huge love marks on the sofas, and extraordinarily long, fine, black hairs all over the bathroom.nike free 3.0 v2 uk
While writing, I sat before a picture window looking out over a fine view of: a well-maintained but completely empty swimming pool, a green Carlsberg Beer billboard written in Thai script, an industrial-scale whorehouse catering to Japanese "businessmen," a rather fine Buddhist temple complex, and, behind that, a district of brand-new high-rise hotels built to cater to the burgeoning information-transfer industry, almost none of which has anything to do with bits and bytes. Tropical storms rolled through, lightning flashed, I sucked down European beers from the minibar and tried to cope with a bad case of information overload. FLAG is a huge project,nike free 4.0 v2 uk sale
bigger and more complicated than many wars, and to visit even chunks of this cable operation is to be floored by it.
For this Instructable first a Tektronix 1241 Logic Analyzer was used, then a Saleae Logic which allowed us to precisely measure the frequency with which frames of data were sent (22ms) including the format, quantity, and content of characters in each byte of its Nike Air Max Shoes uk online
serial protocol (8 data bits, no parity, 1 stop bit), as well as its rate (133000 baud). Each frame contains 14 bytes which can be conveniently represented in hex notation.
Note: The baud rate quite critical. The closest standard baud to our target supported by most if not all serial devices (including the USB to Serial device we require) is 115200. This was too far out from our transmitter and during initial experimentation attempts at communication failed. It became necessary to select a USB to Serial device whose Cheap Nike Air Max 95 uk
chipset permitted the setting of an arbitrary baud rate. For the final version we settled on a model which included a FTDI chipset (specifically the FT232 USB Serial (UART) IC, see Glossary for details).
In our earlier analogy, we stated that the water pressure and level as it flowed through pipes was akin to the voltage level of the electrical current flowing through our circuit, being altered by the "gates" of the joysticks being raised and lowered. As we learned by using the oscilloscope however, the signal Air Max 2012 uk sale
sent between the micro controller and the transmitter chip is digital, not analog. This effectively means that any time we take a measurement the water pipe will either be full, or empty at any given point, never in between. By alternating between these two extremes, binary numbers are being sent.
Another way to think about this is to imagine two people at either end of the pipe, a sender and a receiver. In this case the sender is the micro controller (because it knows the value of the numbers to be sent) and the receiver is the transmitter chip. Attempting to send Nike Blazers online UK
information by flooding and draining the pipes would be very slow, so instead they are using a flashlight to communicate in a form of morse code.
Every so often, the receiver will peek into the pipe and at the same moment the sender will either turn on the flashlight to indicate a one, or leave it off to indicate a zero. Each time this happens a single bit is communicated. This will happen rapidly eight times in a row, forming a byte. If every bit was a letter in a word, the work would be the byte. The logic analyzer further tells us that there are fourteen bytes or "words" in each sentence spoken by the micro controller to the transmitter chip, and each sentence contains all Nike Blazer Low Women shoes
of the joystick settings for each motion direction the remote control is capable of setting. The complete sentence gets constantly repeated approximately 45 times per second (once every 22ms) as long as the remote control is powered on.
The baud rate mentioned above as being critical would be the predetermined timing the sender and received would have agreed upon for sending flashes of light. In other words if the sender is going to send a flash once every five seconds but the receiver was only looking once every ten seconds, the receiver would only Cheap Nike Blazer Low shoes
be there to witness half of the signals, and after the first view would record each of the subsequent bits in the wrong positions within the words they are recording. When we say the baud rate is 133000 what that actually means is there are up to 133,000 individual flashes happening every single second!
After using the oscilloscope to establish a digital signal was being sent between the micro controller and the transmitter chip, and using the logic analyzer to decode the characteristics and content of its serial protocol, it became clear that the easiest method for us to interface with our radio Toms Toms Canvas Classics Mens
controlled helicopter via software would be to bypass all other components and communicate with the transmitter chip direction using a USB to Serial cable. Had this not been the case we might have instead used the analog outputs of an Arduino to simulate the voltage levels normally indicated by the potentiometers.
As the transmitter chip was actually a separate circuit board (see photo) and there was enough clearance on the pins connecting the two for us to clip in, we might have been able to record and analyze all of the data being sent to it from the micro controller without any physically modifications. However we eventually would want to be able to simulate these messages ourselves, which would require powering the transmitter board. If the power switch Nike Blazers for sale uk
of the remote control was on then the micro controller would also be sending data, which would conflict with the data we were generating. If we left the power switch off the transmitter board would also be off, preventing it from sending any data to the helicopter. We considered that we would be able to power the transmitter circuit from the USB to Serial cable, however we were not certain that the electricity applied at this point would not also flow back to the micro controller.
Therefore we decided to desolder the transmitter chip from the remote control entirely as that was the only component we required for certain for our project. Once the transmitter chip was desoldered, we wanted to be able to reconnect the original remote control to it and still fly the helicopter as before, or be able to connect the USB to Serial cable to it and operate the helicopter using software, or be able to connect the remote control to the USB to Serial cable to capture and record data frames directly. We ended up building a simple Cheap Nike Blazer Mid Men
switch circuit using a prototype board which would allow us to flip switches as desired into any of these configurations. In the attached photos we ran this module from a console, issuing the "read" command in the following way:Note: In our specific configuration, the serial port created on our Linux system when the USB to Serial device was attached was "/dev/ttyUSB0" and this may be different for your specific system. Under Windows a COM port such as "COM1" might need to be indicated.
Here is how I added an extension to a bicycle so I could haul boxes of vegetables from a farmer market. The Xtends unit uses a discarded bicycle frame and some electrical tubing. My cost was under $20 but the Xtends unit could be built for free if you have a Nike Free Run sale
good recycle pile. Some bikes are probably better for this project however. I used a 26" bike with a heavy frame for strength. The stays in the rear fork are going to be carrying the load so it helps if they are sturdy.
I pulled this frame from my scrap pile after it had been stripped of handlebar, brakes, chain, front fork, etc. It looks weird because I just put parts back on it that I had lying around. It does support the idea that you can use whatever bike you have as a starting point. ya man make it like a tank man you should be able to pull a car Men Nike Free 3.0 V2 UK
from th e rack its so strong. uhmmm, i got an idea but i dont no if i can explain it with just words but here, it you the middle tube of the rack, were the seat post connects to it. you could have somthing like a seat post, just have it slide out, then those 2 little bars going from the cross bars to the front of the rack "the part that your backs to when your sitting on it" ya those bars you could make "lock in" to a little hole, notch what ever. so just have some bolts(a hinge) so when you want take it off you just slip the "lock" and slide it out. hope ya'll under stand
I think my photos make the pedals look closer to the ground than they really are. I have to tip the extended bike to 40 45 degrees before the pedal hits. That is a lot more tip than I would care to do riding, especially loaded. The main reason for that angle matching stuff in step 3 is to get the chainstays of the Xtend unit to line up with the chainstays of the main bike. You can see this in the first photo in the intro. The chainstays are parallel with the ground and so the pedal height of the extended bike should Cheap Women Nike Free 3.0 V2
be the same as it was before the extension was added. (I think.) You could raise the pedals by adding some blocks between the Xtends unit clamp and the seatstays of the main bike. The angle that the Xtends unit makes with the main frame is easy to adjust.

With the recent storms hitting the northwest there are a lot of bikers piling on the bus or even driving! Though you can order expensive European made studded ice tires, you can also modify your own cross tires into effective ice tires with just a few dollars' worth of rivets. These tires will keep you upright on hard packed snow Nike Blazers online UK
and glare ice. There are other methods for DIY ice tires (like sheet metal screws in mountain bike tires), but these ones made with pop rivets are elegant and suited to narrower tires used on hybrid/cross/touring bikes.
Some steel pop rivets, long enough to reach through the washer and tread. The ones I used were 1/8" capacity, for a pretty ordinary cross tire. If you have very deep tread or puncture resistance layers in your tire you might need longer ones. I wound Nike Blazer Low Women shoes
up using 33 rivets in my rear tire and 90 in the front. Washers just big enough to fit over the rivet body some are usually sold alongside the rivets. Some cyclocross tires (not pictured) I got some off the used rack at my local bike shop. You want tires with some good tread to propel you in snow the rivets will help with ice and strong hardpack.
Thanks for the instructable. I normally don't ride in the winter, but I couldn't wait to get riding this year. I did this for my SS Cross bike. A lot of our city side streets will have mixed pavement, ice, and packed snow for long periods during the winter. Other roads will clear up after a few sunny days, and be bare cold pavement. It is Nike Blazer High Women uk sale
nice to have a tire that can handle the mixed surfaces, without alot of rolling resistance on the dry. First off, I only did one tire for my bike, the front. This is a skinny 30c cross tire. I feel the front is the most critical to keep a bike upright when you hit slippery stuff. I can live with the rear slipping once in a while. I cut off the outermost knobs, and placed a rivet every 5th knob, making 20 per side.
The knobs are about 4" apart along the circumference of the tire. The opposite side is staggered. When the tire is at or near full pressure, the rivets/washers do not make contact at all going straight on dry roads. If you hit crusty packed Nike Blazers for sale uk
snow/ice the rivets make contact. If you are turning, the bike starts to lean, and the rivets make contact. The rivets are at about the same height as the knobs, so they don't really seem to interfere with cornering on dry surfaces. You hear them clicking, but they don't seem to affect the traction (on dry).
On pure shiny ice, I would want more studs, and on the rear, too. But for the mixed condition roads, this is just right. Today, we had fresh snow. I found that lowering the tire pressure helped for that. This is cool, I just learned that biking in the winter can be fun. I have a blog, and I am going to start a series of articles Nike Blazer Low Men shoes
on thrifty bicycle tips. I will feature this instructable in one of my first articles. Update: Have done a few test rides on pavement, dirt and on an ice (a frozen pond) and here are a few thoughts. 1) These work AWESOME on ice. Rode on a frozen pond for an hour without even slipping once. Great traction, it felt like riding on packed limestone. 2) These are wobbly and weird on pavement when descending at speed, and overall lousy on clear pavement. 3)
I lost a few of the washers, but it has made no difference as far as traction. Actually, without the washers the tires look more like store bought studded tires. 4) No flats (knock on wood)! The main thing is that riding on frozen ponds, lakes and streams is amazingly fun, stable, and just plain rad. I had a sht eatin' grin on my face zipping around that pond. Of course, take your speed at 70% tops, and take her easy on turns, but overall not too different from Cheap Nike Blazer Mid Men
normal traction. Thanks again for the clever instructable. Hi, thanks for the idea. I just finished the rear tire and I'm halfway done with the front. It is time consuming, but a fun project. I used 43 rivets in the rear, and will have 80 something up front. Testing out the rear, I would recommend some strips of duct tape lining on the inside for a few of the uglier rivets. Some rivets leave a tiny sharp end on the inside, but most are flush and are causing no problem.
The way I was tought to do it(by my barber, a life long cyclist) is to take quarter inch sheet metal screws and screw them into the tread at regular intervals, line the inside of the tire with duct tape just in case the screws rub against the interior, and slightly Nike Free Run sale
overinflate the tire before use. I later was inspired by the idea to take an old pair of work boots and screw some quarter inch sheet metal screws into the tread, making them pretty effective for gripping on ice, or any sort of slippery substance that can get spilled on the ground at work. Just don't forget to take them off before walking on any sort of wood floor, or any other material that could be easily damaged.
I just finished this procedure on a pair of 26x2" MTB tires and they work great. Predrilled all the holes with a 7/32" drill from the outside of the tire. I found that if I didn't predrill, pushing the rivet from the inside of the tire could rip the nub on the outside. At first I didn't line the inside of the tire with Women Nike Free Run 2 Shoes uk
another tube, and instantly got a flat. now both tires are lined with old tubes. Problem solved. These are loud on the road. Took it out on a pond and the grip was surprisingly good. Overall the task was quicker and easier than I though, and the result really is quite good. But it'll be amazing if anyone actually reads this post by making it past all the flaming comments about how someone reading a dedicated DIY site should just buy studded tires.
A wide flange head type rivet may be more secure than the standard head rivet shown in the lead photo. I expect these would not pull out when locking the brakes on pavement or such. second thought. what about using heavy green package strapping as an inside reinforcement. I refer to the plastic replacement for 3/4 inch wide steel banding used for binding lumber shipments together and dicarded at your local lumber store. that plastic banding Cheap Women Nike Free 3.0 V2
is a versatile product in my experience and it's free. . I have rode my bike in the winter for the last 16 years. If you are buying studded tires I have heard the tungsten carbide ones are the best and will last for usually 3 seasons. I have a pair of Nokians on order, a lower cost version with not as many studs. The really good ones with lots of studs were $120 Canadian a tire which was above my current budget. The cheap studded tires I had years ago had non carbide studs and didn't last, and didn't really do much.
