Systems Building

Recently, a personal computer I built around seven years ago for one of my older brothers died. All heads turned to me since I’m “Uncle Computer Guy” (as my older nephews occasionally call me). Since I have evolved from lowly PC technician to the higher life form of software engineer, I was somewhat reluctant but filial piety won out.

Confucius would be proud.

Out of the back of a bottom drawer came my old computer repair kit, primarily consisting of the primary tools of the trade: a magnetized Philips head screwdriver and a giant flat head screwdriver. These days, most screws on a desktop computer are Philips head, making the Philips head screwdriver the one absolute necessity for PC hardware repair. My personal belief is that the giant flat head screwdriver is also necessary but not for screws. It’s primary purpose is prying apart stubbornly attached components.

Most of the other tools sold in an over-the-counter PC repair toolkit like they used to sell at CompUSA are redundant.  Not that I haven’t had to use other tools on occasion. Once I needed to install a 4 speed CD-ROM in an old Compaq that my dentist had inherited. It had been a corporate workstation so there was a lock on the back of the case to keep all of those employees who love messing with PC hardware during business hours. I had to use a hacksaw to open the case. Other proprietary cases were almost equally nightmarish, taking hours not to actually deal with the hardware but with the nightmares of industrial design that they’d encased the hardware in. Proprietary PC manufacturers seemed to be in a constant race with each other as to  who could come up with the most idiotically designed and poorly manufactured computer case.

When I was building systems for people a decade ago, most of the time I would force them to buy a better quality case than they would get from a proprietary PC vendor like Compaq, Hewlett-Packard, IBM, or Dell. My observations of contemporary proprietary systems hasn’t improved my opinion of these companies’ industrial design skills. While Apple’s industrial design for cases remains unmatched, industrial design by PC manufacturers remains consistently and bafflingly poor. Though many earlier Apple cases are equally awful from a PC repair perspective, Apple towers in the Jobs era have been excellent. The ideal computer case can be summed up in one word: foldout.

The Coming of the Quantum Economy

From FT.com:

Computers set for quantum leap

A new photonic chip that works on light rather than electricity has been built by an international research team, paving the way for the production of ultra-fast quantum computers with capabilities far beyond today’s devices.
 
Future quantum computers will, for example, be able to pull important information out of the biggest databases almost instantaneously. As the amount of electronic data stored worldwide grows exponentially, the technology will make it easier for people to search with precision for what they want.
 
An early application will be to investigate and design complex molecules, such as new drugs and other materials, that cannot be simulated with ordinary computers. More general consumer applications should follow.

I bet.

Proliferation? That horse has bolted.

Steven Den Beste worries that solving our energy problem with small thorium reactors will lead to nuclear proliferation.

I disagree but I don’t do so based on the technical specifics of thorium reactors. I would argue that stopping nuclear proliferation has nothing to do with the non-military use or non-use of any particular technology.

So how do we stop nuclear proliferation? The answer is simple: We can’t.

When people talk about stopping proliferation, they forget one key fact: Nuclear weapons technology is 60 years old. You can’t stop countries from recreating a 60-year-old technology.

Rare Earths

The rare earths are a collection of 17 elements in the periodic table: lanthanum, cerium, and erbium, to name a few. These materials play an important and increasing role in electrical and electronic devices, including batteries and magnets (which are used in electric motors and geherators.) Considerable concern has been raised lately about the concentration of rare-earths production in Chinese hands: see for example today’s Business Insider post, which deals with the Chinese government’s push for consolidation of that country’s rare-earths industry into a smaller number of companies. See also this post regarding dependency of key U.S. military systems on rare earths.

I’m interested in discussing rare earths from two standpoints: overall U.S. economic and security policy, and investment opportunities/risks.
