BASH Coding:How to Code a File Search Tool


This is a small script I helped a member on fix. It will search the entire file system for a file you input and display all locations of the file found. It will also give the directory you are working from. You can run this script from anywhere on the machine, however it will only give file details if the file is located in the same directory.

Hiking the frozen Waterfall

earthquake photography

Last week I had hear from some friends that the waterfall was frozen over around this time of year since it finally got cold to do so. The hike went while substantially more difficult do to the ice and slush, also happened to go quite a bit faster than usual. I’d wager it’s because of all the snow creating a long ramp to the top. In some places the snow was up to my waist or about three feet deep. So between sliding about or sinking into a random pit trap, I finally made it too the top where I managed to snap a few shots of the waterfall:

While I don’t think either of the shots is perfect, I like the blues and contrast on the top one. I also like the more prominent detail of the black and white version.

Since both of these images were composites of…

The computerization of economics: a chronology (in progress)

The Undercover Historian

On Hardware, there’s a great illustrated history of computers here (and timeline). For econometrics software, I relied on Charles Renfro’s massive history. I have tried to classify the various ways in which computerization affected the development of economics here and I list further research questions here. Comments welcome. 

Late 1940s


While the first general-purpose computer, the Electronic Numerical Integrator and Computer (ENIAC) becomes operational in 1946, economists’ fascination with machine is then still related to the utilization of physics metaphors and tools to build economic models. In 1949, for instance, engineers Walter Newlyn and Bill Phillips (of the Phillips curve) built an hydromechanical analogue computer to simulate monetary and national income flows, the MONIAC.

Phillips’s MONIAC

Less known are the analogue electrical-mechanical devices Guy Orcutt built during the 1940s to compute solutions to complex duopoly and spatial location problems, and his regression analyzer.  In these…

Red Flags of Waste in the FY 2017 Defense Budget


FY 2017 Defense Waste“FORBES”

“The defense budget process for 2016 (FY 2017) has just started, with the Administration’s $582.7 defense budget.

Here are red flags of waste:

 Overseas Contingency Operations (OCO). Defense spending is divided into a base amount, in the regular defense spending bill, and another account, OCO, intended for unpredictable wars and commitments abroad, in a supplemental spending bill in 2017. Last year, Congress threatened to put massive amounts of regular weapons purchases into the OCO, to get around spending ceilings (which do not apply to OCO).

Because of last year’s deal about budget ceilings between the President and the Congressional Republicans, it seemed like the OCO maneuver, for padding the defense spending bill, would stop. Wishful thinking. It won’t. The Administration has announced a proposed $59 billion OCO, most of which would actually devoted to overseas operations (although $8 billion is in regular weapons buys). The House majority intends…
