Worth a Read: My Experience With the Great Firewall of China

Most westerners who visit China have a perfectly legitimate reason for evading the GFW: it blocks all Google services. That means no Gmail to access your airline e-ticket, no Hangouts to stay in touch with your family, no Maps to find your hotel, no Drive to access your itinerary document. This was my primary need for evading it.



Software: Warp 17

WARP17, The Stateful Traffic Generator for L1-L7 is a lightweight solution for generating high volumes of session based traffic with very high setup rates. WARP17 currently focuses on L5-L7 application traffic (e.g., HTTP) running on top of TCP as this kind of traffic requires a complete TCP implementation. Nevertheless, WARP17 also supports application traffic running on top of UDP.


Worth a Read: Minimize Frequency Drift In Crystals

Drift can affect systems in different ways. For communications systems, the impact can be significant. Consider a wireless device like a cell phone, tablet, or embedded sensor. As the frequency drifts over time, the device will begin to both experience and cause RF interference problems as it drifts into other frequency bands. It may experience synchronization issues with other devices, reducing performance and reliability.

Worth a Read: Innovation and Investment in IP Interconnection (PDF)

1. Decentralization of the Internet: the emergence of national and regional Internet Exchanges facilitates private peering
arrangements by increasing number of ISPs’ access networks edges in one central location.
2. Commoditization of IP Interconnect prices (falling IP transit, CDN or router costs) led to substitutability of IP Interconnection
products and countervailing powers in the IP Interconnection value chain.
3. Proliferation of Content Delivery Networks: Content & Application Providers leverage the increased value of their Internet
content by building proprietary caching server parks or, alternatively, using independent, commercial CDN services that are
located close to the ISPs’ access networks.
Still, the majority of Internet traffic is progressively being concentrated to a limited number of large Content & Application Providers
and a few wholesale carriers. In 2013, 35 networks carried 50% of all Internet traffic in North America, down from 150 networks in
2009. The concentration of IP traffic is a major evolution in the IP Interconnection value chain, and has the potential to influence the
negotiating power among connectivity stakeholders and affect the current equilibrium in the Internet ecosystem.

Worth a Read: What Really Happened with Vista

I do not claim to have had unique insight during this period. I was frustrated by the focus on these managed code layers and their uselessness for most Office scenarios but I could not articulate the strategic issues clearly. In fact, the OS innovations in iOS were what made it so clear in retrospect how wrong-headed the overall world view driving this work was.

Worth a Read: There Is No Free Market for Electricity

Understanding the sector is not just important because electricity is important; the market for electricity is really a window into the workings of the modern administrative state. The economic regulation of the sector often blurs the line between government and business, turning each into the other’s client. Even in places where competitive features exist, the marketplace is still designed by government and warped by subsidies. Today there is no genuinely free market for electricity.
