Sometimes, children are so excited you just can t resist. Jacob and Oliver have been begging for a train trip for awhile now, so Laura and I took advantage of a day off school to take them to the little town of Galesburg, IL for a couple days.
Galesburg is a special memory for me; nearly 5 years ago, it was the first time
Jacob and I took an Amtrak trip somewhere, just the two of us. And, separately, Laura s first-ever train trip had been to Galesburg to visit friends.
There was excitement in the air. I was asked to supply a bedtime story about trains I did. On the way to the train station in the middle of the night there was excited jabbering about trains. Even when I woke them up, they lept out of bed and raced downstairs, saying, Dad, why aren t you ready yet?
As the train was passing through here at around 4:45AM, and we left home with some time to spare, we did our usual train trip thing of stopping at the one place open at such a time: Druber s Donuts.
Much as Laura and I might have enjoyed some sleep once we got on the train, Jacob and Oliver weren t having it. Way too much excitement was in the air. Jacob had his face pressed against the window much of the time, while Oliver was busy making snake trains from colored clay complete with eyes.
The boys were dressed up in their train hats and engineer overalls, and Jacob kept musing about what would happen if somebody got confused and thought that he was the real engineer. When an Amtrak employee played along with that later, he was quite thrilled!
We were late enough into Galesburg that we ate lunch in the dining car. A second meal there what fun! Here they are anxiously awaiting the announcement that the noon reservations could make their way to the dining car. Oh, and jockeying for position to see who would be first and get to do the all-important job of pushing the button to open the doors between train cars.
Even waiting for your food can be fun.
Upon arriving, we certainly couldn t leave the train station until our train did, even though it was raining.
Right next to the train station is the Discovery Depot Children s Museum. It was a perfect way to spend a few hours. Jacob really enjoyed the building wall, where you can assemble systems that use gravity (really a kinetic/potential energy experiment wall) to funnel rubber balls all over the place. He sticks out his tongue when he s really thinking. Fun to watch.
Meanwhile, Oliver had a great time with the air-powered tube system, complete with several valves that can launch things through a complicated maze of transparent tubes.
They both enjoyed pretending I was injured and giving me rides in the ambulance. I was diagnosed with all sorts of maladies a broken leg, broken nose. One time Jacob held up the pretend stethoscope to me, and I said ribbit. He said, Dad, you ve got a bad case of frog! You will be in the hospital 190 days! Later I would make up things like I think my gezotnix is all froibled and I was ordered to never leave the ambulance again. He told the story of this several times.
After the museum closed, we ate supper. Keep in mind the boys had been up since the middle of the night without sleeping and were still doing quite well! They did start to look a bit drowsy I thought Oliver was about to fall asleep, but then their food came. And at the hotel, they were perfectly happy to invent games involving jumping off the bed.
Saturday, we rode over to Peck Park. We had heard about this park from members of our church in Kansas, but oddly even the taxi drivers hadn t ever heard of it. It s well known as a good place to watch trains, as it has two active lines that cross each other at a rail bridge. And sure enough, in only a little while, we took in several trains.
The rest of that morning, we explored Galesburg. We visited an antique mall and museum, saw the square downtown, and checked out a few of the shops my favorite was the Stray Cat, featuring sort of a storefront version of Etsy with people selling art from recycled objects. But that wasn t really the boys thing, so we drifted out of there on our way to lunch at Baked, where we had some delicious deep-dish pizza.
After that, we still had some time to kill before getting back on the train. We discussed our options. And what do you know we ended up back at the children s museum. We stopped at a bakery to get the fixins for a light supper on the train, and ate a nice meal in the dining car once we got on. Then, this time, they actually slept.
Before long, it was 3AM again and time to get back off the train. Oliver was zonked out sleepy. Somehow I managed to get his coat and backpack on him despite him being totally limp, and carried him downstairs to get off the train. Pretty soon we walked to our car and drove home.
We tucked them in, and then finally tucked ourselves in. Sometimes being really tired is well worth it.
Back in March I was given an LG G Watch R, the first Android Wear smartwatch to have a full round display (the Moto 360 was earlier, but has a bit cut off the bottom of the actual display). I d promised I d get round to making some comments about it once I d had it for a while and have failed to do so until now. Note that this is very much comments on the watch from a user point of view; I haven t got to the point of trying to do any development or other hacking of it.
Firstly, it s important to note I already was wearing a watch and have been doing so for all of my adult life. Just a basic, unobtrusive analogue watch (I ve had a couple since I was 18, before that it was pretty much every type of calculator watch available at some point), but I can t remember a period where I didn t. The G Watch R is bulkier than what I was previously wearing, but I haven t found it obtrusive. And I love the way it looks; if you don t look closely it doesn t look like a smart watch (and really it s only the screen that gives it away).
Secondly, I already would have taken my watch off at night and when I was showering. So while the fact that the battery on the G Watch R will really only last a day and a half is by far and away its most annoying problem, it s not as bad as it could be for me. The supplied charging dock is magnetic, so it lives on my beside table and I just drop the watch in it when I go to bed.
With those details out of the way, what have I thought of it? It s certainly a neat gadget. Being able to see my notifications without having to take my phone out of my pocket is more convenient than I expected - especially when it s something like an unimportant email that I can then easily dismiss by swiping the watch face. My agenda being just a flick away, very convenient, particularly when I m still at the stage of trying to remember where my next lecture is. Having walking directions from Google Maps show up on the watch (and be accompanied by a gentle vibration when I need to change direction) is pretty handy too. The ability to take pictures via the phone camera, not so much. Perhaps if it showed me roughly what I was about to photograph, but without that it s no easier than using the phone interface. It s mostly an interface for consuming information - I ve tried the text to SMS interface a few times, but it s just not reliable enough that I d choose to use it.
I ve also been pleased to see it get several updates from LG in the time I ve had it. First the upgrade from Wear 4.4 to Wear 5.1 (probably via 5.0 but I forget), but also the enabling of wifi support. The hardware could always support this, but initially Android Wear didn t and then there was some uncertainty about the FCC certification for the G Watch R. I can t say I use it much (mostly the phone is within range) but it s nice to see the improvements in support when they re available.
What about the downsides? Battery life, as mentioned above, is definitely the major one. Mostly a day is fine, but the problem comes if I m ever away. There s no way to charge without the charging dock, so that becomes another things I have to pack. And it s really annoying to have your watch go dead on you midday when you forget to do so. I also had a period where I d frequently (at least once a week) find an Android Wear isn t responding. Wait/Restart? error on the watch screen. Not cool, but thankfully seems to have stopped happening. Finally there s the additional resource requirements it puts on the phone. I have a fairly basic Moto G 4G that already struggles with Ingress and Chrome at the same time, so adding yet another thing running all the time doesn t help. I m sure I could make use of a few more apps if I was more comfortable with loading the phone.
The notable point for me with the watch was DebConf. I d decided not to bring it, not wanting the hassle of dealing with the daily charging. I switched back to my old analogue watch (a Timex, if you care). And proceeded to spend 3 days looking at it every time my phone vibrated before realising that I couldn t do that. That marked the point where I accepted that I was definitely seeing benefits from having a smart watch. So when I was away for a week at the start of September, I brought the charger with me (at some point I ll get round to a second base for travel). I was glad I d done so. I m not sure I m yet at the point I d replace it in the event it died, but on the whole I m more of a convert that I was expecting to be.

Not bad for 23 lines of code, is that? Seems much less tedious to do things
this way than using ncurses. Even with its panels, ncurses requires you to
think about layout of various things on the screen, and many low-level
details. This, by contrast, is compositional, just add another region and a
thread to update it, and away it goes.
So, here's an apt-like download progress display, in 30 lines of code.
Not only does it have regions which are individual lines of the screen,
but those can have sub-regions within them as seen here (and so on).
And, log-type messages automatically scroll up above the regions.

So, my thought was that the video stream is not corrupt. It just is rendering at a slower frame rate. So, there were 2 problems. 1: Video rendering slower than the usual 30 fps rate. 2: As a result of 1, audio not being in sync with video.
Thanks to gpac tools, even a novice, I was able to quickly separate the streams. And then re-encode the video stream into 30 fps. And then merge the audio + video stream together. And the result: Just awesome.
