Why America cannot be fixed through government/politics

Book: Hillbilly EulogyI just read a short review of a book that tells a specific story about the helplessness and hopelessness of growing up poor in rural America with a drug-addicted, single mother. The book titled A Hillbilly Eulogy: A Memoir of a Family and Culture in Crisis by J.D. Vance sounds like it is a painful but truly enlightening read. This post is not about the book–it is now on my reading list, but I have not read it yet. It was something that was said in the review that captured a truth of which many people with a similar world view to my own have been reminded due to the trajectory of culture, politics and government today in America. It is about the source of our current problems and the direction from which the only hope for a solution can come:

The book demonstrates in spades that there is no simple statist solution to the so-called “plight of the working poor.” Vance’s experience shows that the problems in these communities lie far beyond the reach of the nanny state. Rather, broken people produce broken cultures and social pathologies. The only way to fix the culture and eliminate the pathologies is to fix the people. And that is the primary conflict of the book. Can people really change? Indeed, Vance’s own doubt about whether he himself could truly escape the demons of his past is one of the most poignant aspects of this story. It is clear that the problems he describes are primarily moral/spiritual in nature, and therefore so are the solutions.

The article has motivated me to make the effort to read a book that is sure to be a painful but worthy exercise. The review article will give you a sense for what you might be getting yourself into.

Nothing comes from Nothing. Something NEVER comes from nothing.

Lots has been made about activist atheist Lawrence Krauss’s attempt to equate a quantum vacuum with nothing. Krauss was not mentioned by name in a post on a blog that is new to me named Popular Science in English and Divulgación de la Ciencia in Spanish. The author seems to be quite an impressive man with a long, very technical career as well as authorship of technical articles, musical pieces, poetry and even children’s literature. I am absolutely adding him to my list of blogs of interest. Here is his quote from the the article on “something” coming from “nothing”:

[Out] of nothing one can create nothing. Nothing does not exist, as we know since the time of Parmenides. As usual, nothing is confused with the vacuum. A vacuum is not nothing, because it has several qualities (space, time, energy, existence) that nothing does not have. Our current theories about quantum vacuum cannot be wholly correct, for they predict that the energy of the vacuum is infinite. Physicists solve this problem by a mathematical procedure called renormalization, a process that essentially involves dividing by infinity (which is forbidden by mathematics), equivalent to hiding the problem under the carpet.

Update: An insightful comment a day later from a blog that discussed the above post–

Even more basic, the quantum vacuum presumes quantum theory which is not nothing. In fact, all physical theories including quantum mechanics presume an existent universe of things. Physics is just accounting. It accounts for the correlation between things now and things later (or previously). It can not account for the things itself.

Live webcam app with OpenCV and Wt libraries


The purpose of this video is to show the status of my work on an application to process live video in real time from a webcam (or other camera) using OpenCV and the Wt libraries. I will try to get this up and running live on the Internet from my BeagleBone Black in the next few days.

Pushback on Christian’s latest blog post

Christian recently wrote a technical post on his blog about demosaicing of images captured with Fujifilms new X-trans sensor. He tested some methods to perform the demosaicing, wrote a first pass of his own demosaicing code and then posted about it all on the blog. That kind of thing is pretty interesting to guys who work in that area and/or have cameras. He got a couple of nice comments on the blog post itself, but what boggled my mind was that some guy wrote this over on Hacker News where his article got some coverage:

[sic] someone is wasting a [sic] phd scholarship to solve a problem that only [sic] exist because people keep dumping money on a company that damages their own product by now releasing source or specs?

What a tool. That is like saying people are wasting McDonald’s, Amazon’s or the local donut shop’s money to solve a problem just because the guy solving the problem happens to work for that company. PhD scholarship students are not slaves. Some of their time is their own. Beside that, Christian is not on scholarship. He is a Research Fellow and A Dean’s Fellow, so he is an employee, just like if he were working at McDonald’s, Amazon or the local donut shop. And who cares how the problem was caused. People have the problem and it an interesting problem. Why not solve it? What kind of a waste of oxygen writes a comment like that?

CoffeeSig web GUI

CoffeeSig single camera GUI startI spent much of the day today trying to figure out how to use CSS to control the way the web pages look in the Wt application I am writing. This is the one I hope to use to learn how to capture images from 1-n cameras to the web with analysis in real-time. It is fun, interesting and frustrating all at the same time. The funny deal is the frustrating part is that it is difficult to get all browser types to behave the same way. I have decided I will just aim at Firefox and Chrome because they are the most ubiquitous in my little world. The companies that make those browsers have, in my humble opinion, very sketchy reputations, but that is another story for another time.

The next step will be to start hooking up the camera. I think I might go back to the license plate reader as my first application for this thing, but I am not sure yet. When I get a camera hooked up that is controllable from my local network with a browser, I will port it over to the little BeagleBone Black I have been running as a web server that does not do much from the apartment for quite awhile now. My buddy John H. from Arizona is helping with this whole thing. He will be a big help because we will be getting into some pretty serious 3d/time domain image processing here as we get past the one camera application.

Chronological snobbery and biblical archeology

"House of David" inscriptionJust a day after I wrote a post on The Veracity of the Bible which included links to articles about fairly recent archaeological discoveries that confirm the biblical record, Eric Metaxas wrote an article that describes the blinders worn by much of academia when they evaluate these kinds of new evidences. In the article, titled A Flood of Evidence, Chronological Snobbery and Archeology, he describes a concept using terms first coined by C.S. Lewis. The article starts out like this:

In his conversion story, “Surprised by Joy,” C. S. Lewis explains how his close friend, Owen Barfield, demolished his “chronological snobbery.” Lewis defined chronological snobbery as “the uncritical acceptance of the intellectual climate of our own age and the assumption that whatever has gone out of date is on that count discredited.”

In Lewis’s time, much of academia was already convinced that every past generation formed a staircase of progress, leading (of course) to enlightened modernity. And since Lewis’s death, many intellectuals have only become more convinced of their own perch at the pinnacle of history. These days, we barely even notice the snobbery.

Metaxas goes on to list some relatively recent discoveries with links to some great articles about what they mean with respect to the veracity of the biblical record. An example of one of the discoveries is described in a post on the same site about confirmation that King David was an actual, living breathing person (the famous Tel Dan Stele). There are additional links in and after the story to additional confirmations. Then he goes on to describe the silliness of chronological snobbery and how it dampens the acquisition of a better understanding of ancient history.

Balloon chasing

My buddy Bryan out chasing balloons this morning. I texted him way to early in the morning for him to be up, but he was out having fun. It is a great time of year to be up early in the Willamette Valley. Nothing like it. Envious.

The veracity of the Bible revisited

Dead Sea Scroll FragmentOne of our most fondly remembered homeschool outings was a visit to the traveling exhibition of the Dead Sea Scrolls at the North Carolina Museum of Natural Sciences back in 2008 when the kids were in their early teens. It was particularly exciting for me because it had been a hobby, an avocation really, to read Ancient Near East history for the previous twenty five years to try to get an understanding of what we really know about the events that transpired in the Old and New Testaments. Of course the New Testament and the events surrounding Jesus’ time here on Earth or the most well attested events in antiquity as represented by the documents available to us today and the proximity in time of those documents to the actual events. As part of our world view studies in homeschool, we studied all these things carefully and it was nice to see the artifacts themselves. That this exhibit arrived in Raleigh was coincident with our studies was truly serendipitous.

The Old Testament is so far removed from us that, historically speaking, it is a lot more difficult to find the level of verification for those events from either the available documentary evidence or from archeology. Still, there not nothing and what there is continues to confirm the biblical record. I was very happy to find a couple of articles that talked to all these issues in the last couple of days. The first is a blog post about the way the canon of the New Testament was selected. It put into one article what it took me a long time to figure out reading about it piecemeal. The upshot is hat 22 of the books of the New Testament, the gospels, the Acts, Paul’s epistles (including Hebrews), I Peter, I John and Revelations have always been universally recognized as canonical. In addition, things like the Gospel of Thomas, the Gospel of Peter, the Acts of John, etc. have been considered to be heretical from antiquity. There are a couple of other categories that describe how the canon got to 27 books and no more. I highly recommend this concise article titled An Essential Key to Understanding the Development of the NT Canon.

In addition to that, I found a blog post titled Historical Reliability of the Old Testament: Resources for Study. It is a series of links to articles about what we do know and what we don’t know, historically speaking, about the Old Testament. The articles talk about the controversies, the archeology, etc. of the Exodus, the Babylonian exile and other events and persons in the Old Testament. I good survey of what we know today and a good place to start (from the list) is this article by Peter J. Williams.

Walking at lunch time.

Only mad dogs and Englishmen go out in the noon day sun.Only mad dogs and Englishmen go out in the noon day sun. I walk to and from a grocery store every work day to buy myself some lunch and get some exercise. I am beginning to realize that unless I want to remain damp from the exertion for most of the rest of the afternoon, I need to think about doing my exercising in the gym after work. That is really not nearly as satisfying as walking outside everyday, so I will probably just be damp until things start to cool down in a month or two. The walk was optimal at my last job in Oregon–it was a little further and a lot cooler. Still, I am thinking it is going to be great here in the Dallas area for all but a couple of months in the winter and a couple of months in the summer.

For the first time in a year and a half, I bought new shoes

I am quite pleased with myself. I bought new Rockport walking shoes when I moved to Oregon and wore them out walking five miles per day for over 1000 miles. Yesterday, I was the fattest I have ever been in my entire life, so I bought some new Rockports that should get here tomorrow. I hope to do a lot of walking in them. In addition, I got myself my first pair, ever Chukka boots. Nothing quite as uniquely satisfying as a new pair of shoes.

My BeagleBone website server and learning new stuff

home dev site screenshot
Learning new things keeps me sane. The reality is that it is hard work to learn new stuff and I am not that fond of new stuff. I am fond, though, of having learned new hard stuff. I am currently on a kick to upgrade my programming skills. A lot of programming is minutiae–a massive jigsaw puzzle of minutiae tied together with clever tricks and best practices that are not always obvious. Right after I arrived in Texas I worked on a webified version of my old GaugeCam project software. I did not get very far–just some user interface stuff, but I put it onto a little BeagleBone Black embedded computer that runs Xubuntu and serves the site from our little apartment. You can access the site by clicking here (not so much to see). The thing has been up and running for several months now. I am kind of amazed.

The upshot is that I thought I would change the focus of my learning effort a little, put up a second page on the same server and see if I could serve live images from two cameras and do some realtime image analysis all from this wimpy little embedded computer. I started on it last night. We will see if I get anywhere with it over the next few months.

A truly astounding video

I was amazed and I laughed. What more can you ask from a YouTube video of less than a minute?

Dog bites man, press misleads public

There are a continuous stream of reminders for why thoughtful people should not get their news from the main stream media. In an article titled New York Post flubs the strange case of a liberal church and a lesbian minister’s pension, Terry Mattingly of the religious journalism watchdog site GetReligion.org discusses the outrageous misrepresentations made by the NY Post in an article they titled, Lesbian pastor’s widow takes on church to get pension payments. It reminded me of a set of articles written about a homosexual man who was an acquaintance–a friend of a family member, but got caught abusing a boy who was his foster child. It was a horrible, very sad affair. The way the events were reported in the main stream press led people to believe the guy was a serious church goer, but neglected to say he actually taught sexuality classes to eighth and ninth graders at a very liberal Unitarian (who reject the beliefs of historical Christianity) until deep into the articles if they were reported at all. You can read about it and follow links to a couple of the articles on this topic here, here and here.

Maybe I do not get any respect, but I never miss a plane

Kelly sent me this link: Dad Suggests Arriving At Airport 14 Hours Early. I did not see the humor in it. Not even a little bit. This is probably why I am so well read.

Oddly productive, unproductive weekend

Kiwi and I studying hard over the weekend
Lorena and I planned to drive to Wichita last Friday for a working weekend. I turned out that the people with whom we were to work planned to leave after lunch on Saturday so we decided a conference call working session made a lot more sense than twelve hours of driving followed by four hours of work. I have a ton of things to accomplish at my day job and planned to spend the bulk of what time I had left on the weekend for that. I accomplished two things: the conference call (four hours on Saturday morning) and a lot of “contemplation” sessions with Kiwi like the one shown in the image above. Well, there was a little bit more to it than that–Kelly and Christian both called and we talked for long stretches on life and their current paths.

The talks with Kelly and Christian were the most productive parts of the weekend. Christian is at about the halfway point of his PhD program, living through the pain of his third Tempe summer and the bloom of graduate school is definitely off the rose. He is in a good place with his work–he and his professor are performing the final edits on a paper about the research he has performed over the last two years which they will submit in the next week or so. On the other hand, he spends so much time working, there is little time for anything else, so he is looking forward to the day when he can get a regular job where he goes to work in the morning, goes home in the evening and has weekends off–all in a place where the daytime temperature only hits triple digits four or five days per year.

Kelly, on the other hand, is not so enamored with the actual day to day work of her degree. She does not think she wants to do marketing research and/or be an academic, so she is trying to decide whether to finish where she just to have her graduate school complete forever, or switch graduate schools and go back to a degree and field that is a little bit more rigorous–probably in the use of statistics. It is a hard decision, but she has a great opportunity to go either way. The good thing is that she is thinking about it objectively. It might be worth it to just finish out–she is in a good place to do that academically, but if she hates it, she might be better served to step back, reconsider what she wants and move onto something for which she has a passion.

A bigger office!

I have been at my current day job for about four months. My normal stay at a job is usually in the one to three year range because I am usually there to solve a narrow, very specific hard problem that, when it is solved, they have no more need for the likes of me. This time, though, there was a prefect storm. When I first got there, I got put into an office with a door that had a lock because it was over on the business (as opposed to engineering) side of the house. The lock was a pain in the neck because I had to use my key on Thursdays and Mondays to get in after the cleaning people came the night before. Now, the business is doing well, so they hired a new business guy which was timed by one of the technical guys moving on to another job and leaving me a double size office with a beautiful wood desk and a window. Alright, the window is one of those tall narrow ones beside the door that looks out onto the hallway, but it is still a window. Feels good!

The Amazon interview “bait and switch”

Christian sent me a great article about a guy who got “bait and switched” by the Amazon interview process. The title of the article is My Interviews with Amazon. Full disclosure: Amazon has approached me three times. I made it through the first interview to the second time one time before I got feed up and told them to not call me back. I was smarter on the next two passes, telling them I was not interested at the outset. Amazon has a reputation as notoriously bad place to work. It might not be as bad as Apple, but it seems to be pretty bad. Even though I love their services and prices, I am rethinking how much I really want to spend with them.

My experience in the interviews I had with Amazon were very much in the same vein as that described in the article. The funny deal is that I have a good friend who works for them at a high level. He is good at his job, but the first product he worked on for them (a famous hand-held device they tried to make) failed miserably. The reason they interviewed me was because they knew I had the exact skills they wanted from the mouth of one of their most highly regarded scientists, but were willing to treat me badly enough in the interview that I knew working for them was something I would neither do nor advise any of my highly skilled colleagues to consider.

Take harder classes in high school? A better idea is to skip it altogether.

After hammering on The Atlantic yesterday for shoddy reporting, I found an article they published that suggests that taking harder classes in high school does not necessarily translate to future success in college. The article is titled When the Value of High School Is Exaggerated, but whose title on the tab of my browser is Success in High School Doesn’t Mean Good Grades in College. I think both titles and the articles point describe our experience well:

Instead, the pair [who did the research on which the article was based] thinks that if high schools want to prepare students for college, they should focus less on specific content and more on critical thinking and reasoning. Most students will forget the specifics of, say, mitosis shortly after they take their AP biology exam, but they might retain the broader concepts of conducting an experiment and presenting evidence. “It’s really the underlying skills that stay with people,” Hershbein said. That may be one reason that calculus seems to be the one exception in the research, where students who have exposure in high school benefit “mildly” in terms of better college grades. That’s “probably because it is based on cumulative learning to a greater extent than other subjects,” the authors note.

Our premise all along has been that there are a lot of students who could easily transition to community college after the eighth grade. This allows the students to avoid the academic and cultural malaise that characterize the vast majority of traditional schools in America (government and private) and move into an environment much better suited for success in their future endeavors. The community college system in the US is profoundly better at preparing students for life after school either in a trade or further educational endeavor at a four year college. You can read about our experience pursuing that path in the series of posts on this blog titled Why Not Skip High School?
