Nokia Siemens: LTE more than higher speeds
"LTE will offer latency below 20 milliseconds, which is about half that of current HSPA (High-Speed Packet Access) networks and much lower than the 120 milliseconds of GSM."Good news. Low latency is definitely a big part of perceived speed, even for regular web surfing.

"A secure, decentralized, data store. This filesystem is encrypted and spread over multiple peers in such a way that it remains available even when some of the peers are unavailable, malfunctioning, or malicious."

"More than a million people in China, including human rights activists and expatriates, are using special software to circumvent the nation’s complex online censorship system, known as the “Great Firewall.” This has created a booming market for software companies..." The Internet sees censorship as a business opportunity and markets around it.December 19 2009
Gadget Patrol: 21st century phone [Charles Stross]
Great essay on the future of smartphones and cell networks. "The real message here is that if Google succeeds, the economic basis of your mobile telephony service in 2019 is going to be unrecognizably different from that of 2009. ... What's good for the internet is good for Google. Right now, the phone companies are not good for the internet. If I'm right about the grand strategy, the Googlephone will change that."December 03 2009
Google Public DNS
"Google Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your current DNS provider." I've been trying it out for a few months; it makes web surfing at home noticeably faster. Just set your DNS servers to 8.8.8.8 and 8.8.4.4.July 08 2009
What is AmbientTalk about? [ Ambient-Oriented Programming]
"Ambient-Oriented programming is a programming paradigm whose properties are derived from the characteristics of hardware platforms for mobile computing. Mobile hardware devices are often provided with wireless networks facilities, allowing them to engage in collaboration with their environment. However, the autonomous nature of these devices as well as the volatile connections over their wireless infrastructure has its repercussions on the software that employs them. The basic assumption of the Ambient-Oriented Programming paradigm is that languages should incorporate possible network failures at the heart of their programming model."February 25 2009

What Carriers Aren’t Eager to Tell You About Texting - NYTimes.com
“But text messages are not just tiny; they are also free riders, tucked into what’s called a control channel, space reserved for operation of the wireless network. ... The channel uses space whether or not a text message is inserted. “‘Operating costs are relatively insensitive to volume,’ he said. ‘It doesn’t cost the carrier much more to transmit a hundred million messages than a million.’”October 05 2008
Network Applications of Bloom Filters: A Survey
"A Bloom filer is an ingenious randomized data-structure for concisely representing a set in order to support approximate membership queries ... Bloom's beautiful approach has seen a sudden resurgence in a variety of large-scale network applications such as shared web caches, query routing, and replica location. This survey presents a plethora of recent uses of this old data structure"September 18 2008
Panda - Open source video platform
"Panda is an open source solution for video uploading, encoding and streaming." The interesting part is that it runs in Amazon EC2 -- it's a prefab server image you just unzip into an EC2 virtual server and run there. This is an interesting midway point between huge centralized systems, and locally-run servers.August 30 2008
Revealed: The Internet's Biggest Security Hole
"The tactic exploits the internet routing protocol BGP (Border Gateway Protocol) to let an attacker surreptitiously monitor unencrypted internet traffic anywhere in the world, and even modify it before it reaches its destination."
