Beaglebone Black made it to the internet

gaugecam_BeagleBoneBlackThe beginnings of the new Beaglebone Black based GaugeCam software have finally made it to the internet. I have it up on our dev site right now. As soon as I have it a little further along with a camera hooked up and some of the basic functionality working I will let everyone know where it is.

The GaugeCam team is currently in talks about how we want to move forward with this project, especially with regard to whether we want to Open Source the software or keep the whole project commercial. We are still several months away from making any decision about that kind of thing, but it would be nice to get this camera based water level measurement tool into the hands of more people who might be able to use it.

Running LXQt on the Beaglebone Black

BBB_wTightVNCI spent last evening working on the Beaglebone Black embedded computer for our GaugeCam project. I set the computer up to run on the home network, then installed Subversion, Qt Creator, OpenCV, Wt and Boost–the libraries I use to develop the application. It worked, but it worked so slowly I have decided to rethink the whole thing. Tonight and tomorrow, I am going to try to get a cross compiler going so that I can do all my development on my home computer, then just download the program to the Beaglebone. It dawned on me that the Beaglebone might not have the horsepower we need to run the GaugeCam application. If that is true I will have to rethink this whole thing, but I am going to do some testing to see whether it meets our need. The Beaglebone Black is an amazing little computer with great documentation and a very active user community. I still have a lot of hope that it will work.

Community college and big projects

There is a great community college where Lorena will have a good chance to finish her degree within six minutes of our apartment. There was never any doubt about that. The system of community colleges in the United States is, along with the homeschool movement, the greatest educational hope for our country. Pretty much everything else about our educational systems are either bad or getting that way rapidly.

Lorena will almost certainly wait until the Fall to get started, but that means I will have to find a project to keep me busy and out of trouble while she studies. I think she could probably finish up within three or four semesters at one or two classes per semester. I think that will give me the time I need to finish up with the current phase of our GaugeCam project. She is checking the whole thing out and plans to start getting all her transcripts sent to the right place today. So far, she has been to five different community colleges–three in Oregon and two in North Carolina. This will be her first in Texas.

Starting back on the Beaglebone Black

BeagleBoneBlackA brand new Beaglebone Black embedded computer arrived to our apartment yesterday. I plan to use it on our GaugeCam project. I would like to say it is for work or business, but there is no money in it and stuff like this is so much fun it is pretty hard to call it work. I have talked about some of my projects over the years on this blog, but I have never really explained in any detail what it is, exactly, that I am doing. I am going to take a stab at changing that with this project. At GaugeCam, we put small cameras out in very remote places (e.g. the tidal marsh of North Carolina) to measure the height of water in streams, lakes and other bodies of water. The problem out in places like that is the lack of power and connectivity (no Wifi), so we have to get our power from solar panels connected to batteries. The problem is compounded by the fact that we need to run the cameras 24/7–the solar panels do not work at night. Until now, we have communicated the images back to our internet server where they can be seen via cell phone connection and the server can calculate how high is the water in the scene. For some locations, not even that is available so we will eventually have to figure out how to transmit the images via satellite. We have a working system that does now.

What is new is that we want to turn all the cameras in the field into web servers. To do that the cameras need to be able to calculate the height of image, form a web page and serve the web page–something, as was just mentioned that is currently being done up on the server. That is the goal. We will see if we can make it happen.

Settling into life in Texas

There are lots of good reasons to move from Oregon to Texas. There is the fact that Texas has no state income tax nor does it have an outrageously high minimum wage that kills off small businesses. There is still a sense that individual liberty, morality and responsibility mean something and are not on the wane as in many, more liberal parts of the country. Honestly, I am very glad to be here. We have reengaged with old friends and made new ones during the short time we have been back.

For me, there is nothing like being in Texas to make me realize who I am and, especially, from where I come. I am an enthusiastic fan of Texas, its people and everything about it, but I say that as an outsider.  Even though I have lived in Texas two different times for several years both as a student and as a working engineer, I am an Oregonian, heart and soul. What makes me sad about this is that the Oregon from whence I came no longer exists or, if it does, it is well hidden. Maybe I feel this way because my last couple of stints in Oregon were in places, Portland and Corvallis, whose cultures have coarsened greatly in my lifetime.

We are here in Texas to be closer to Lorena’s mother in Northern Mexico. We are not sure where we will land for retirement because so many things are in flux with the kids and aging parents, but Dallas is a fine retirement place.  There are great people here. We are close to our beloved Monterrey. The food fits us to a T.  The weather is acceptable. The mountains, ocean and vegetation are less so, but I will trade that for a government that stays in its place and does not dictate immorality any day.

Kelly’s last Easter birthday

Kelly visits us before her birthday 2016Our daughter, Kelly’s birthday lands on Easter today. She checked it out the last time that happened when she was eleven and this will never happen again in her lifetime. So this is a special birthday. She came to visit us for a week, but had to leave after a small, early celebration. She is in a very good place right now. She has very good friends in Seattle. She struggled early in her PhD program, but just finished her best term ever. The picture with this post shows her sitting at her computer working through some of her research. More important than all that and above all, she considers God and her place in this world relative to his will. We are so thankful God lent her to us even it is just for a little while.

Kelly was a beautiful baby. One of the first things we noticed about her when she was born, after the full head of black hair and the blue eyes, was that she had a little butterfly birthmark on her left forearm. You can see it close to her elbow in the picture. It beats the monster Rorschach test birthmark I have on my back all hollow (even though I am quite fond of my birthmark).

It is fitting that today I used up the last Betty Blonde comic Kelly drew as part of her homeschool education. I think there are a few that I lost, because there are some missing dates and we never missed a date (five times per week) in the five years she drew them. Still, 501 is a good number of comics. She drew them from when she was 14 until she was 16 for an absolutely stellar run. The quality of the comics improved greatly over that time. She really hopes she can get back to that one day–maybe not to draw Betty Blonde, but something new.

Happy Birthday Kelly. We love you.

Short term health care

I learned today that Obamacare is every bit as evil as it is represented to be. I also learned that the affordable health care available from some insurance companies is not eligible for avoidance of the draconian health care tax required by our increasingly totalitarian, but abjectly immoral executive branch of the government. Fortunately, the bridge insurance I need to get during my job change is only required for a couple of months. If it were for four months, I would get nailed. This is definitely cause for sadness and trepidation. What is happening to our country.

First visit to new job

I visited my new work today to meet my new boss and get the lay of the land. It is going to be great. Not only do I get to work on a product that will help the helpless, but I will be able to uniquely contribute. I will be working purely in Linux. It is all C/C++. It does not get much better than that.

Dallas Museum of Art

2016-03-20-DMA-MonetLorena, Kelly, Christian and I all went to the  Dallas Museum of Art. It is wildly impressive. The picture with this blog post is of me with an original Claude Monet. There were Pissarros, Manets, Gaugins and much, much more. It was at least as good as the North Carolina Museum of Art and we truly love the North Carolina Museum of Art. We have just touched the tip of the iceberg in Dallas and are looking forward to much, much more.

Up and running in Texas

We left Christian’s place in Tempe last Sunday afternoon to arrive at Lorena’s cousin Beto’s place in Mesquite, Texas on Monday evening. The next day we had the extreme good fortune to find a great little apartment in Lewisville a short way from my work and only a half a block from Anytime Fitness. The proximity to Anytime Fitness was a happy accident that made Lorena very, very pleased. We stayed with Beto two nights and have been in the apartment since.

LewisvilleNewWasherDryerSince we arrived, we have been out buying “stuff.” Since we sold the old washer and dryer, the gas barbecue grill and all our beds we had to replace all that or go to the laundromat, cook on the electric range and sleep on the floor. We will have to continue to sleep on the floor until Monday because the Nebraska Furniture Mart does not deliver our bed until then. Amazingly, we got the best price on the washer and dryer from the Lowes right around the corner from us and it included free delivery and installation. We still need to buy a breakfast nook table and a sofa, but after that we will wait until we are in a house before we do too much more furnishing of the house.

It is great to be back in the saddle blogging again.

Kelly goes to the opera with Aunt Julia and Uncle Rich

Kelly goes to the opera in Seattle with Uncle Rich and Aunt JuliaAunt Julia and Uncle Rich drove up to Seattle to see the opera last night. I got Kelly a ticket as a gift for surviving a period of insane school intensity. I think she is finally over the hump and has figured out both what is required, but also that it is also possible to for her to do what is required and have a life. That is actually, I think, a very big and important breakthrough.

Kelly bought a new dress for the affair and Uncle Rich and Aunt Julia took her to a really nice dinner. Kelly was a wildly big fan of her Aunt and Uncle before the opera, but even more so now. Her is Aunt Julia’s very insightful quote about the opera:

It was great. Mary Queen of Scots gets killed in the end by the declaration of the evil queen Elizabeth after much hand wringing, agony and weeping.

Just so. That would probably be a good description of many operas if you switched the names out and maybe added a little sword waving and romance.

Thank you Uncle Rich and Aunt Julia. We are grateful for your efforts on our daughter’s behalf. The only thing that might have made it just a little bit better is if it would have been a Russian opera!

Lazy days in Tempe along with quasiconvex optimization

Lazy days with Kiwi in TempeLorena spent the whole day cleaning and cooking. She had the time of her life. It is counterintuitive to me how those first two sentences hang together. Part of it had to do with the fact that she bought him a new mop. Looking back at that last sentence, I concede that, still, none of this makes a whole lot of sense to me. Lorena picked up Christian after school, just like the old days at NCSU and they went down to Target to buy “stuff.” Both of them had a ball. I am losing hope that I will figure out all the joy associated with these events. On the other hand, I hung around in the apartment all day, did nothing and felt really good about it for the first tie in years.

Christian was at school today for his bi-weekly meeting with his sponsor from MIT. The difference about today’s meeting was the quasiconvex optimization proof Christian did for his research. He has been working on it for the last several months and he finally got it figured out since after we arrived. It was a big relief for him, but I have no clue what any of it means. Still, like Conoscopic Holography, even though you have no idea what it means, you know it must be great because it sounds so cool.

A visit to Christian in Arizona

Lorena hits Anytime Fitness in ArizonaWe are taking a brief hiatus in Tempe to visit Christian in our road trip to Texas. Lorena needs to get her workouts in. She explained it is not so much that she is fanatical about doing it, she just hates the pain of starting all over again when she has missed a week or two. She is actually up to two 35 minute sessions per week on the elliptical and three 60 minute sessions per week on the Concept II rowing machine with some weight lifting thrown in the mix, too. It pains me just thinking about it.

In the meantime, we get to see Christian mostly just in the evenings because he has to work even though it is spring break for the undergraduates. He remains dedicated to his research. I think the classes are just a pain in the neck for him now even though he says he learns some stuff.

We plan to continue on to Texas right after Sunday morning meeting.

Lorena’s last Oregon flower garden blooms the day before we leave

Tulips on the fourth floor balcony gardenLorena loves to grow flowers. She did a vegetable garden last year in the Wilsonville community garden areas. She loves her vegetables but she is crazy about flowers. She bought a wrought iron flower box holder for our balcony and was very gratified her tulips bloomed before we left. She has already donated the flowers to Gladys, but hung on to the flower box holder. We hope to get some ficus trees for inside the house as soon as we get to Texas.

All our bags are packed and we’re ready to go

All our earthly goods in a UHaul headed from Oregon to TexasThis morning we packed all of the things we had accumulated from a year of fourth floor studio apartment living in Wilsonville, Oregon into a 5×8 U-Haul. It is amazing how much stuff one accumulates, even in such a cramped space. Dinner is planned tonight with our dear friend Gladys followed by church tomorrow morning and evening with Grandpa Milo and Grandma Sarah. After that, we are off to Texas.

It has amazed us how everything worked out for us to return to Oregon, but then nothing worked out after that for us to stay. We are not too excited about spending too much more time in an apartment so we are working hard to find a house where we can settle down for the long term. In the meantime, we look forward to some time with Christian in Tempe next week.

Last day of work in Oregon

I am scheduled to go out to lunch with my manager and several others today as it is my last day of work at my job here in Oregon. These are always melancholy things. My theory is that work is never as bad as one thinks it is while they are in it, but never really quite as good as they remember it after they leave. The work in this job I am leaving is not nearly as “bleeding edge” as I hoped, but it has been a great place to be to have the chance to spend a year close to Grandpa Milo and Grandma Sarah. I am very grateful for my time here, but look forward to some new and very interesting challenges.

We pack this weekend. We do not have much because we never got out of our fourth floor studio apartment into a house. Everything should fit into a 5×8 U-Haul trailer. Lorena took our Honda CRV to get a trailer hitch so we are all set to go. I pick up the trailer and we plan to pack tomorrow. Kiwi the remaining twin cat sister, Lorena and I should be on the road to Tempe for a visit with Christian early Monday morning.

Will Kelly share her art with us again?

KellyCaricatureKelly went to a conference in Las Vegas. While she was there, here group gambled at the craps table for a little while. Since did not gamble, one of the guys in the group had her roll the dice for her several times and she won him $300. The guy gave her $25 for her trouble which she promptly blew on the drawing she holds in the picture. It was from a slightly tipsy street artist and you can see it is a monumentally bad likeness. You know what they way about ill-gotten gains!

This has inspired Kelly to start to share her art once again. She has started a new Instagram account named Betty Blonde Draws. She has her first three caricatures up there now. They are very good likenesses, but of the very quickly drawn ones. She plans to do more quick ones, but she also plans to spend some time to create some that are more thoughtfully drawn.

This is all great because she is kind of an amazing caricaturist. One of biggest worries is that the kids would have a lousy art education if we homeschooled. It turns out the had a fairly amazing art education including the study of art history. Maybe it was because I am so weak myself in that area, we worked harder to make sure we overcame my weakness. It is certainly true that I also received much more art than I had before we started the effort.

So if you want to be drawn, send her a picture of yourself. She is always looking for more material.

Help from old friends

Kindness for Grandpa Milo and Grandpa Sarah by old friends provided a great, very much needed boost to our move to Texas yesterday. It is hard to express how grateful we are for these friends who have agreed to take on the far from inconsiderable task of getting Grandpa Milo to church. It is really hard for Grandma Sarah to get out much at all any more. These friends met with Grandpa Milo and Grandma Sarah for Sunday and Wednesday meetings for over twenty years, understand Grandpa Milo in his infirmities better than just about anyone else. This is truly a gift, not only from them, but from God.

Grandpa Milo, Alzheimer’s and Sports

When we drive Grandpa Milo to church, we have time to talk with him. It is a lot of fun and we always learn something. We have to talk about things that happened a long time ago because his short term memory is not so good. Our talk yesterday, as usual was a gift to us. We talked about when he played sports in elementary school and high school in Cottage Grove, Oregon back in the 1940’s. One of my favorite stories that I have heard often was when his high school basketball was doing well, but not as well as the coach desired.

The coach gathered the team around and asked the question in what, I suppose was a rhetorical way, “Are you here to have fun or are you here to win!?”

That was probably the wrong thing to ask a bunch of extremely hard working farmer and logger boys whose brothers had just come back from fighting World War II. Sports were definitively not anything to be taken seriously. No one believed then that the “courage” and “sacrifice” required to participate in sports were a good way to build character. Nor did they believe the exercise they got playing them was anywhere close to the physical duress they experienced when working on the farm or in the woods. So, the idea that it was a builder of character was transparently wrong. That left sports as something to do for fun and, to a much smaller extent, exercise.

Grandpa answered for all of them, “We play for fun. As soon as this quits being fun, we will quit playing basketball.”

Maybe we ought to get back to thinking that way about sports again in our day.

Davy Crockett went to Texas under similar circumstances

We really are going to Texas to try to balance family responsibilities. We have wonderful friends here in Oregon, I am a native son, we love the unparalleled beauty and we even love the weather (most of the time). That being said, Davy Crockett’s famous quote when he resigned from the U.S. House of Representatives resonates with us. He said, “…you may all go to hell and I will go to Texas.” The reason it resonates with us has to do with the draconian land use laws, the horrible Portland freeways, the outrageous new minimum wage that will drive small business into the ground, the abysmal public education system and a coarsening libertine culture that is abortion friendly, anti-traditional marriage and, frequently anti-Christian.

Oregon, we love you and our roots are here, but unless law, culture and our personal responsibilities change, to paraphrase Oregon governor Tom McCall, “We will come visit again and again… But for heaven’s sake, we don’t plan to come here to live.”
