The Next Decade, George Friedman, 2010
This book looks at the near future of US foreign relations in terms of a realignment of the balance of power through actions of the President as Commander-in-Chief. There are two themes, the unintended empire, and whether it can be managed to allow the republic to survive. The US global military supports economic policy. Its President is always engaged in the art of war. This will move beyond recent fear of rising oil prices and Jihadist war and establish surrogates in each region. While democracy, human rights and social progress are still important, strategy becomes more of a concern than ideology. The issues are economic, geopolitical, demographic and technological. There is an aging population, contracting workforce, and lack of water. The state, in the form of the DoD, is more powerful than the market for long-term investment. On the American contents, Cuba is likely to be a target of influence, Latin America will include Brazil, Argentina and Mexico. The latter’s violence and corruption will be resisted at the border and cartels are expected to be in control there, while US hypocrisy will scapegoat members of its government staff during investigations. Canada is stable. In Asia, Korea, Australia and Singapore balance Chinese splintering and Japanese assertiveness. India surges economically, but is not a threat to China, and is balanced by Pakistan to keep its expenditures on Army and Air. In Europe, Brits’ interests are closer to US, and Poland is important to containment since Germany dominates economically, backed by France allied with Russian military which seeks to balance US with radical Islam. Denmark blocks Baltic sea exits. NATO is irrelevant. In the Middle East, US withdraws from Iraq, distances from Israel, and has detente with Iran. Sunni Turkey eventually rises and is important to Russian containment in Balkans and Caucasus. There are fourteen chapters.

“It prospered strangely, and did soon disperse
Through all the earth:
For they that taste it do rehearse
That virtue lies therein”,
George Herbert, Peace, 1633.
In this case the wide-spread subject is virtualization. This makes a computer or storage system look like many to its users. Popularity is due to the costs and power saved by not having to load up on hardware, often to meet a temporary peak demand, and the agility in fielding appropriate infrastructure and applications. Sometimes it is as easy as drawing a capacity plan and having the hypervisor and virtual machine monitor assemble the hardware emulation software automatically on hosted servers, tuning each virtual machine (VM) instance’s portion of resources such as processor instruction cycles, memory or bandwidth for proper load balancing.
The techniques sprang from time-sharing, portable OSes, and redundant storage devices. Of course, hardware was also often developed using simulation and functionality implemented in firmware. Now the bare metal can host a layer which mimics popular processor, memory, I/O, and network switch architectures so that off-the-shelf applications can run anywhere, operating system optional, and migration is easier. This is offered for servers, desktops, phones and data centers. The approach spans cloud, grid, parallel and high-performance computing (HPC) systems. Vendors include VMWare, Microsoft, IBM, Intel, Oracle, Cisco and many others. There are open-source versions which lower cost further if vendor support is not necessary, e.g. Xen and KVM. Hardware may also have virtualization built in as a multiplier and for compatibility to a variety of interfaces, for instance.
System management is significant since integration issues are likely and software may require licensing. A virtual machine often has to reboot when a bug causes a crash, but the rest of the VMs run intact. Version changes introduce risk. Infrastructure patches cause side-effects to virtual apps. It is possible to mix various ratios of physical and virtual components. Performance may be adversely affected by additional virtualization layers. VM sprawl makes end-to-end administration more difficult. The visibility and testing tools need improvement. Standard quality measures can still be taken, such as use cases, architectural review, and measures of functionality, usability, security, scalability and performance. Benchmarking in VMs may have time drift.
Users, developers and administrators can expect to see this topic expand as more virtual appliances are developed. Here is an example introductory Glossary.

IT might have a future where it can strategically edit a map of this century based on actual and projected conditions. Various types of networks interact to realize scenarios. Each continent has players. Population growth changes demographics. Ideally can preserve civilization commons such as health, rights, law and trade. Dependencies include at least energy, natural resources, transportation and communication. Disruptions to states lead to realignments in treaties and rivalries. Downing big guardians can result in various melees, so there may be attempts to order conflicts to preserve security, lower intensity and defuse escalation, though these still have to deal with surprise attacks and arms dealers. Issues of national security may be construed as threat to species whether from war (conventional, WMD, guerrilla, cyber, nano), climate warming, pandemics or natural disasters. New powers may emerge, e.g. Turkey, Poland, Mexico and Brazil. Politics range across democratic, socialist, communist, religious, martial and possibly growing sympathy among distributed small groups. Complex human emotions often seem two-sided, e.g. fear/greed, mortality/sex, or group-power/free-will. Simultaneously, science offers prospects of augmented physiology, cloning, smarter machines, robotics, and conquering space. Waiting on reality transport protocol.
Topics of interest include network support by Allen 2009, software test by Davis 2009, survival fiction by Forstchen 2009, hardware design verification by Fujita 2007 and Martin 2007, and hardware testability by Wang 2006.

Whether the internet is the primary achievement of the age, on a par with the wonders of the world, is yet to be seen, though the polar ice caps seem to be yielding quicker. As more components are joined, it seems to become like materials such as wood, metal, and plastic which are used extensively to rework structures, in this case adding interactive behaviors. Internet protocol is second-nature for networked machines. Other robust standards can therefore be built upon it. If a part of the web disappears, for example, it is relatively straightforward for it to grow back. It is not considered a biological phenomenon which would regenerate without knowledgeable human supporters, but that can possibly be emulated using automation that adjusts for prevalent local elements. As new regions are built out, and history is rewritten, each social region may take credit for inventing the thing, presumably finding workarounds for previous gotchas, the most immediate of which include at least spam, censorship, and weather. The last might be averted if the environment was allowed to give feedback symbolically rather than dramatically which might lead to advances in the areas of look-ahead, testability and accessibility, e.g. if coupled with augmented mobile sensing. Dangling some non-specific user-interfaces at various scales might hook unexpected demonstrations of intelligence if not new actors. At least, it could lead to some new ringtones.
Books included Boleyn-Fitzgerald 2010 on cognitive mapping (in process), Osherove 2009 on unit testing, Wang 2007 on hw test, Johnson 2006 on virtual instruments, and Munden 2004 on hw verification.

Popular media is awash in sci-fi. Summer is an optimistic season. The final year of the decade is seen as a pivotal manifestation of change in approaches to issues. Human history is treated as a runaway which various groups are scrambling to deal with in order to define and position themselves for whatever is ahead. Depending upon perspective, one may simultaneously be experiencing growth on the order of multiples of previous levels of experience, as well as a disconcerting collapse of structures which had previously been relied upon for responsibility. In a time series, this can be portrayed as a changing of the guard, or alternatively considered as transition from nationalist vertical to globalized flat, or other domains may see length of time shift to height of relevance, or orthogonal rotation of moments, and so on. The next decade may attempt to maintain part of this through economics. Optimistically, an inclusive balance sustains the good, realistically society continues to cater to a market of might, and pragmatically, correlations of ideas across previous boundaries connect various people in unexpected ways.
Titles from the reading list were Hibbs 2009 and Pezzè 2008 on software testing, Singer 2009 on military robotics, Wolf 2008 on VLSI design, and Aezel 2001 on quantum physics.
