Hello From Flushing



Steve Jobs


I ordered the book. That was months ago. If you know what I mean. And waited, and waited, and waited. Finally I went online to Amazon.com and filed a complaint. I never received the book, I said. I was immediately refunded. I used that money to immediately reorder. This time I was closely tracking the delivery. One notice said, delivery attempted. Two days later the notice said, delivered. Delivered? I never received the book. I went to the post office. They gave me a print out. See? Delivered. They said. I talked to pretty much everyone in the building, including the landlord. No book, nowhere to be found. I figured either the post office lied to me, not very likely, or there is a Steve Jobs fan in the building. Or the delivery man himself is a Steve Jobs fan. I went online to Amazon. This time there was no refund. The book was delivered, they said. I did not get the book, I said.

Oh well, I thought.

Today I bought the book from this sidewalk bookseller. The cover price said 35 dollars. I haggled. I looked interested, then I walked away. The guy came after me. He said 30. I said 25. He said okay. I don't have the cash, I said. I need to get money from the bank. How long, he asked. Five minutes, I said. Then I reached into my pocket. I had 21 dollars. This is all I have, I said. You can have this right away and I will take the book. He thought for a split second. He looked at me. He took the money, and gave me the book. I could not believe it. I had just brought the price down by 14 dollars. When will you be back, he asked. When will you be back with the four dollars? Five minutes, I said. And I walked over to the ATM at the bank on the same block. On my way back I bought a mango lassi for two dollars. So I had a 10 dollar bill, a five dollar bill and three one dollar bills. 20 minus two is 18. I gave him three dollars. I was trying to get one dollar ahead. He took it. Then he grabbed my mango lassi. Can I have it, he asked. Sure, I said. He made it look like he gave me the book for 24 dollars when we had already brought the price down to 25 from 35. Mango lassi does not count for payment, it counts as hospitality.

I don't know if he got one dollar ahead, or I did. But I finally have the book now. This sidewalk bookseller just beat Amazon in delivery - instant - price - really low - and there is no way Amazon can match the experience.

Tip: try haggling.

"Where you from?" I asked as I walked away.

"Bangladesh!"

60 Milli Seconds

Bathymetric/topographic map of the Arctic Ocea...Bathymetric/topographic map of the Arctic Ocean and the surrounding islands (Photo credit: Wikipedia)The ocean route might make sense for inter-continental destinations, but I think air is still the best option for dense cities.

ExtremeTech: $1.5 billion: The cost of cutting London-Toyko latency by 60ms
the first ever trans-Arctic Ocean submarine fiber optic cables ...... a smattering of branches that will provide high-speed internet access to a handful of Arctic Circle communities ....... All three cables are being laid for the same reasons: Redundancy and speed. As it stands, it takes roughly 230 milliseconds for a packet to go from London to Tokyo; the new cables will reduce this by 30% to 170ms. This speed-up will be gained by virtue of a much shorter run: Currently, packets from the UK to Japan either have to traverse Europe, the Middle East, and the Indian Ocean, or the Atlantic, US, and Pacific, both routes racking up around 15,000 miles in the process. It’s only 10,000 miles (16,000km) across the Arctic Ocean, and you don’t have to mess around with any land crossings, either. ...... The massive drop in latency is expected to supercharge algorithmic stock market trading, where a difference of a few milliseconds can gain (or lose) millions of dollars. It is for this reason that a new cable is currently being laid between the UK and US — it will cost $300 million and shave “just” six milliseconds off the fastest link currently available. The lower latency will also be a boon to other technologies that hinge heavily on the internet, such as telemedicine (and teleconferencing) and education. Telephone calls and live news coverage would also enjoy the significantly lower latency. Each of the fiber optic cables will have a capacity in the terabits-per-second range ..... Currently, almost every cable that lands in Asia goes through a choke point in the Middle East or the Luzon Strait between the Philippine and South China seas. If a ship were to drag an anchor across the wrong patch of seabed, billions of people could wake up to find themselves either completely disconnected from the internet or surfing with dial-up-like speeds. The three new cables will all come down from the north of Japan, through the relatively-empty Bering Sea — and the Arctic Ocean, where each of the cables will run for more than 5,000 miles, is one of the least-trafficked parts of the world. That said, the cables will still have to be laid hundreds of meters below the surface to avoid the tails of roving icebergs
New Scientist: Fibre optics to connect Japan to the UK – via the Arctic
In mid-August, construction should start on the first submarine fibre-optic cables to cross the Arctic Ocean ....... The longest of these links will become the world's longest single stretch of optical fibre. ....... the biggest threats to cables in warmer waters: fishing trawlers and ships' anchors ........ Reduced transmission time will be a boon for high-frequency traders who will gain crucial milliseconds on each automated trade. Optical amplifiers will boost signal strength every 50 to 100 kilometres. The firm also plans to drill a tunnel 40 metres deep to take a shortcut through the Boothia isthmus in the Canadian Arctic ....... Isolated Arctic communities will also be connected by extra sections of cable that branch off from the main one. ........ "choke points" such as the Luzon strait near Taiwan, the strait of Malacca between Indonesia and Malaysia, and the crowded and politically unsettled Middle East. ....... Ships must be built to withstand the pounding of ice as well as waves. ...... Icebergs can plough more than a metre into the ocean floor, endangering cables. Greenland's icebergs extend to depths as great as 170 metres below the sea surface, so Arctic Fibre will lay cable at least 600 metres deep in the Davis strait, where icebergs are most likely. The underside of sea ice also has ridges, or "bummocks", that reach depths of 18 metres, so Arctic Fibre aims to stay at least 50 metres down.
Ars Technica: Europe moving 60 ms closer to Japan with new undersea cables
The climate change-induced retreat of Arctic ice has had one positive effect. The Arctic Ocean is now sufficiently navigable that cable-laying ships will be able to plant undersea cables directly linking London with Tokyo. ...... 6 pairs of fibers with a 1.6 Tbit/s capacity per pair will be laid, and minimum latency between London and Tokyo will be 76.58 milliseconds.
