Fortune Cookie in Hex Code
It is an old hack. On boot-up, the computer displays a random good-luck saying. I chose 60 of them and called the seconds counter of the system clock to point to one. I wrote it in hex in Debug.

BASIC: Turing’s Truth
Alan Turing showed that any finite-state machine can model any other. … Earlier this month, I answered a challenge from the Praetorian computer security company to decipher this block of text: “Mpyza johsslunl ZWXY, Zluhabz Wvwbsbzxbl Yvthubz … Zll fvb vu aol ihaaslmplsk.” To do that, I wrote a program in BASIC.

Awesome Austin Foods
Locally crafted foods abound here in Austin. Lovebean produces a confectionery fudge made from coconut oil, coconut nectar, and cacao beans. Jade Monk teas are packets of powders. Technically, not local to Austin, Perdenales Brewing is located in Fredericksburg. Baby Zack’s smoked hummus brings an array of Texas flavors to this international staple and snack treat.

“Documentation for Developers” was the topic when I addressed my Ruby on Rails group. I spoke on the subject of private security to my local DefCon group. I volunteered to present a chapter of exercises from Wireshark 101 to an OWASP lunchtime study cell.
PowerPoint slides for “Physical Security for Data Centers” here.

Redshirts: Expendable in Fiction and Fact
Seeing in the Dark by Timothy Ferris is a narrative rhapsody honoring amateur astronomy. You do not need even a telescope to be blessed by the wonder of the skies. City lights are not a barrier. Certainly, a large telescope deep in the countryside, above the surrounding landscape is best. Building your own observatory is the epitome of the hobby. But for anyone, anywhere, passion and patience deliver the rewards. Seeing in the Dark is about the people whose love and work open the universe for themselves and others.

FRIDAY, MARCH 15, 2013: Another day and night of fun and splendor as 6th and Congress remains the focal point of energy in downtown Austin. On Saturday, March 15, Oliver and Wilder Lee moved across the street. Balafon player Abou Sylla returned from last year. The Yellow Roses returned from yesterday. The Magician and Sonia did not.
These were some of the people who worked the intersection of 6th and Congress on Thursday. Blues and bluegrass, rock or skittle, tuba, xylophone, acoustic and electric, break dancing, no corner goes unoccupied for long. These shots were possible only in the moments when the on-lookers were sparse. To get me to work, we just waited for traffic to stall and did a “fire drill.” Later, on my way to a bus stop after work, I found the poet Bill Keys up a block, once again surrounded by girls. (Oh, why I did choose technical writing?)
Chamber of Commerce Biobash February 2013
Before and after the presentation, Austin life science professionals enjoyed hors d’oeuvres – courtesy of the Chamber of Commerce – and the opportunity to sit and talk with each other about their interests. Maggie Bishop of the Chamber made sure that I met Dr. Tim Meehan of Saber Astronautics. (Tim and I actually met at Benjamin’s Meetup last month.) I also met Samantha Fechtel, executive administrator of the Texas Medical Accelerator, Joe Smith director of technology innovation for Globiox, Jim and Sabine Accuntius whose Research Equipment Alliance is selling femto-second lasers for histology and similar research. (Calling them microtomes is three orders of magnitude too large.) Sharon Manley just joined Growth Acceleration Partners/Mobius as their new business development specialist. Although we talk a lot about “cloud computing” most of our work is done on the ground, and so, Christopher L. Marchbanks from Cresa Austin (“The Tenants Advantage”) was also at the Biobash.
Autobiography of a Worker
Growing up, I did not acquire a good work ethic. What I did well at I did more of, but I never learned to work through a problem to gain a skill. I quit practicing the piano as soon as my younger brother eclipsed me. We competed by being successful at different activities in school. I did not work for money until I was legally of age. At my first summer job (in a hospital laboratory), I was more of a pain than a help. I liked sterilizing labware – which is to say that my best skill was washing dishes. Then, I read Atlas Shrugged. Twice.
Atlas Shrugged is too easily mischaracterized as a glorification of the rich. It is truly an anthem to all workers. Growing up in Cleveland, I knew the Rearden Steel mills (Republic and Jones & Laughlin), the Taggart Terminal (the Terminal Tower), and Patrick Henry University (Western Reserve University).
After two years at the College of Charleston (1967-1969), I came home to work at the Are-Jay Game Company making wooden games and puzzles. I ran drill presses and sanders. Mostly, I sprayed lacquer. I also learned to box shipments and fill out a UPS book and bills of lading. Between stints at Are-Jay, I worked for an employment agency. There, I attended a sales training series and practiced Approach-Benefit-Close making 60 phone calls a day.
After we got married, Coletta and I moved to Lansing. I worked a lot of spot labor jobs, mostly through Manpower. (Fifteen years later, I interviewed the franchise owner for a four-part series on “Quality” published by the Greater Lansing Business Monthly.) Finally, after about a year of that, Coletta said, “Mick, you need a real job.” So, I got on the phone, and a few pitches later I had an interview at Montgomery Ward. I worked there for two years as a stock boy, unloading trucks and distributing goods to the floor.
About a year into that, passing through Lansing Community College to see else I could learn, I picked up a brochure for a certificate in transportation and traffic management. It was a two-year course in government regulations of common carriers. It was painful. But I finished. And I went to work as a dispatcher for a regional truck line. That was 1976.
Toward the end of the course sequence, one of my classmates from General Motors said, “You know, Mike, these computers are going to be everywhere some day and you should find out how they work so the people from data processing can’t hand you a bunch of baloney.” So, I did. I had a semester of Business Programming in Fortran IV and got a C+, having no idea what I was supposed to have learned for the grade. But it was compelling. While working for the trucking company during the day, at night I learned to hack free time at the LCC and MSU computer labs. I took Fortran again (for an A); and then learned Basic in the LCC arts and science division. The class was experimental and resisted by the data processing curriculum of the business division. I met my present wife because we had the same instructor for physics and Basic, Claude Watson. (Man and the Computer by John G. Kemeny reviewed on NecessaryFacts here.)
Laurel and I moved to Las Cruces, New Mexico. I worked as mover’s helper for Bekins Van Lines until I got hired by the NMSU’s Physical Science Laboratory and was assigned to White Sands Missile Range as a computer programmer in Basic on Hewlett Packard desktop micros. Eighteen months later, we moved back to Lansing. Our daughter was born (1979).
Both Aristotle and William Graham Sumner pointed out that laws are only expressions of tradition. To cite the terminology of Thomas Kuhn, only a paradigm shift can change a folkway. A hundred years ago, Bhagat Singh Thind (a veteran of the U.S. Army in World War I) was denied citizenship on racial grounds: though admittedly a speaker of an “Aryan” language, the U.S. Supreme Court found that he was “Asian” and therefore not qualified to become a citizen, despite his honorable service in the armed forces. Almost at that very moment, the self-taught Srinivasa Ramanujan was astounding the mathematics faculty at Cambridge.
The numbers speak. 12. 5 crore Indians use English, whereas only half as many in the UK do the same. When the USA invaded Iraq, I distrusted the American news media and sought international coverage. India’s English language newspaper websites provided some objectivity. One of them also delivered this: “Bush Ploy Foxes Pundits.” I could put the foxes in a bush, but I knew that “he pundits” is incorrect: pundit is a noun. So, I reparsed the sentence.
We think that our vernacular is the standard, but Jews who speak Yiddish have an old joke: “What is the difference between a language and dialect? Dialects do not have armies.” The so-called standard language is only the local dialect of the capital city. See, for example, The King’s English by Henry Watson Fowler and Francis George Fowler (Oxford: Clarendon Press , 1906), which was published at the height of the British empire. But Rudyard Kipling was the first English language writer to be honored with the Nobel Prize in Literature (1907) and he was born in Mumbai. (Ironically, the Fowlers complained that Kipling introduced Americanisms into his prose.)
Now, India has an army (with nuclear weapons) and …
Twenty percent of scientists are crooks. At university in both Introduction to Criminology and the Senior Seminar in Criminolgy, our professor, Liqun Cao liked to cite an easy claim of “twenty percent.” The exact numbers – 18.3% or 23.9% – did not matter and neither did the specific study or survey. The teaching point was that criminality is not unusual. Heinous crimes are rare. Daily harms are all too frequent – and we all engage in one or another of them whether speeding or padding expense accounts. So, too, in science is it important to realize that fraud and misconduct in research are not rare.
False Prophets: Fraud and Error in Science and Medicine by Alexander Kohn (Oxford: Basil Blackwell: 1986), is a classic work that remains important. It sets a baseline for understanding fraud and misconduct in research. Kohn repeats famous cases such as Margaret Mead, Robert Millikan, and Trofim D. Lysenko. He also tells of N-rays, the Allison Effect, the Davis and Barnes Effect,, and polywater. From there, Kohn focuses on his special interest, clinical research. The book closes with chapters on broad and deep issues in ethics and science.

Criminality and Scientific Research:Why Scientists Go Wrong; and Why the Wrong People Become Scientists
On 6 April , a federal district judge in Boston, Massachusetts, dismissed a lawsuit that I had filed in 2009 under the US Freedom of Information Act. He concluded that the US government does not have to release a report on an investigation into a case of alleged scientific misconduct at a national laboratory. The ruling was disappointing but liberating: I finally had occasion to write about a case that has shown how the US Department of Energy (DOE) takes a strikingly hands-off approach to the oversight of such investigations.

University oversight committees focus on human factors. We seek to protect individuals from unintended harm during experiments and surveys in psychology and sociology. But you cannot hurt a chemical or a star. Short of serendipity, we only find what we seek.
