Financial academics and other experts often recommend that investors should use index mutual funds to invest in entire markets. This advice is common with both stocks and bonds and with both domestic and international investing. Why do we so often hear this advice? When is it appropriate for an individual investor to not follow it or to use it as a starting point but deviate from it?
For this series we try to look for patterns which become visible only over an extended time period. As development of a system proceeds, early decisions can have consequences that were not fully appreciated when they were made. If we can find patterns relating these decisions to their outcomes, it might be hoped that a review of these patterns while making new decisions will help to avoid old mistakes or to leverage established successes.
Unless developed economies learn to compete the old-fashioned way - by making more goods and making them better - the smart money will continue to move offshore to Asia, Brazil and their developing economy counterparts, both in asset and in currency space.
The broken windows theory states that monitoring and maintaining urban environments in a well-ordered condition may prevent further vandalism as well as an escalation into more serious crime.
With the growing prominence of Asian financial markets, we often are asked, "How much should I allocate to Asia?" Thoughts on how Asia fits within a globally diversified portfolio.
When playing this simple non-zero-sum game, people consistently reject the rational choice. In fact, by acting illogically, they end up reaping a larger reward--an outcome that demands a new kind of formal reasoning.
From its unheralded beginning, the Soviet Union’s modest little gun, dubbed the Avtomat Kalashnikova-47, would become one of the most recognizable artifacts of the 20th century.
We argue that the challenge of future multicore hardware is best met by embracing the networked nature of the machine, rethinking OS architecture using ideas from distributed systems. We investigate a new OS structure, the multikernel, that treats the machine as a network of independent cores, assumes no inter-core sharing at the lowest level, and moves traditional OS functionality to a distributed system of processes that communicate via message-passing.
The Fed’s announcement of a renewed commitment to Quantitative Easing has been well telegraphed and the market’s reaction is likely to be subdued.
We are in a “liquidity trap,” where interest rates or trillions in asset purchases may not stimulate borrowing or lending because consumer demand is just not there.
The Fed’s announcement will likely signify the end of a great 30-year bull market in bonds and the necessity for bond managers and, yes, equity managers to adjust to a new environment.
RAID based on the magnetic disk technology developed for personal computers, offers an attractive alternative to SLED, promising improvements of an order of magnitude in performance, reliability, power consumption, and scalability.
Pennsylvania sits atop one of the world’s largest natural gas reservoirs, promising clean energy and new jobs. But can this resource be extracted sustainably?
U.S. energy industry innovators unlocked the natural gas found in deep shale rock by combining and super-charging old oil industry techniques.
Hopes are high that jobs will flow as fast as the natural gas in the energy boom that has hit Pennsylvania.
The shale gas industry maintains that it safeguards the environment, but accidents have sown mistrust as the industry has moved into rural communities.
Overall principles of how to organize a business and get rich.
Really isolated groups are at a disadvantage, because most groups get most of their ideas and innovations from the outside.
You don't want excessive unity and you don't want excessive fragmentation; instead, you want your human society or business to be broken up into a number of groups which compete with each other but which also maintain relatively free communication with each other.
Foxes bred for tamability in a 40-year experiment exhibit remarkable transformations that suggest an interplay between behavioral genetics and development.
Why there is no silver bullet that slays the software productivity monster.
Why the very nature of software makes it unlikely that there will be any silver bullets in future. No inventions that will do for software productivity, reliability, and simplicity what electronics, transistors, and large-scale integration did for computer hardware.
Accidental and essential complexity. Advocates addressing the essential parts of the software process. Believes that a series of innovations attacking essential complexity could lead to significant improvements.
Why witchcraft trials in renaissance Europe were practiced on a large-scale violence and scapegoating prompted by deterioration in economic conditions.
Details of data collected for trails and weather showing systematic evidence of a relation between witch trials, weather and economic growth. Within the renaissance cultural framework witches became targets for blame.
Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio.
Views on populations past and present effects on human happiness. An enquiry into our prospects respecting the future removal or mitigation of the evils which population occasions.
Hamming's observations and research on "Why do so few scientists make significant contributions and so many are forgotten in the long run ?". What Hamming has learned in terms of the properties of the individual scientists, their abilities, traits, working habits, attitudes, and philosophy.
Magazines: A per-CPU caching scheme called the magazine layer that provides linear scaling to any number of CPUs.
Vmem: A general resource allocator, vmem, that can satisfy allocations and frees of any size in guaranteed constant time. The allocator can manage arbitrary sets of integers (not just virtual memory). Linear scalability to any number of CPUs. Low fragmentation.
Slab allocator improvements: Object caching for any vmem arena. Reclaim callbacks to notify clients when the arena's resources are running low.
