My 2012 instructions for building node.js on OpenIndiana still work on recent bits. Now to write some software.
I learned that Logitech has brought the Squeezebox product line to end to life. I’m not prepared to replace (or research what might replace) our current audio infrastructure, so I’m experimenting with a piCorePlayer install to see if a low cost, Raspberry Pi solution can solve this problem, much like OpenSprinkler has addressed home irrigation.
We went on a drive today, to try Fletch’s Chicago-style hot dogs and sliders. They make their own dipping sauce, which has a touch of spice and went well with the fries. I couldn’t muster the appetite, but there is a Beard Papa on the very same block of 2nd Ave.
I just started the spring season in my recreational soccer league last weekend. And I’m still using Adidas’s miCoach system to record statistics in each game. Earlier I showed a couple of individual sessions, with image captures from the miCoach site. Here I’m going to summarize the season, and compare it to the previous season (Summer 2013). Top line summary of the season
- 11 games, 9/8 – 12/29
- 8 goals
- Compared to 1 in Summer 2013
- All on turf
For the quantities tracked by the Speed Cell, we have a group of measurements, summarized as follows
- Distance: 4.0 ± 0.6 miles per game, with a best of 5.1 miles on 12/1. (Improved over Summer 2013, 3.9 ± 0.5 mpg.)
- Sprints: 20.5 ± 4.5 sprints per game, with a best of 30 on 12/1. (Improved over Summer 2013, 18.5 ± 4.7 spg.)
- Maximum speed: 15.0 ± 0.4 mph, with a best of 15.52 mph on 9/15 and 10/6. (Improved over Summer, 2013 14.5 ± 1.1 mph.)
miCoach offers badges (“achievements”) for various performance levels: on 12/1, 5.1 miles of total distance and 0.55 miles of “hi intensity distance” resulted in the Pro achievements for those two categories. Still haven’t reached the Pro mark for Maximum Speed, which I suspect will require a burst over 16 mph. (On 6/9, 3.9 miles of distance and 15.17 mph maximum speed earned the respective Club achievements. On 7/14, 0.38 miles of high intensity distance earned the corresponding Club achievement.)
I was pretty happy with my showing on December 1, but Sean Ingle’s Sunday article in The Guardian, on Chelsea and England defender Ashley Cole, shows how low on the performance scale these numbers are:
The additional physical demands are clear from Prozone’s data. In 2003-04 Premier League full-backs made an average of 29.5 sprints – any movement greater than seven metres a second – over a game. This season that figure is exactly 50. A decade ago the average recovery time for a full-back between high-intensity activities – any movement greater than 5.5m/s, or a three-quarters speed run – was 56.4sec. Now it is 40.4sec.
(Of course, I’m ten years older than Ashley Cole, so I am pleased just to be on the field, uninjured, and possessing a little bit of pace.)
It’s going to be hard to compare the spring season with this one, as the new team only has part-time goalkeepers, and I’ll have to take many more shifts in net. (The two times I played keeper during the fall were 13 sprint games.) Other than working on my metrics, my only goal for this season is to finally score one on the grass fields.
As I mentioned in the sprinkler repair/upgrade post, Northern California continues its now multi-year drought. The United States Drought Monitor currently labels the conditions as D2 – severe drought.
Early last summer, Nathaniel was in the back yard, practicing his kicks into our KixKube. One particularly strong kick missed the cube, and smashed into the exposed sprinkler valves, breaking through the ¾” PVC pipe below one of the valves. The break led immediately to that portion of the garden and lawn being covered in water, so I rushed to close the water main at the street and then scurried to Home Depot to get a PVC cap and fresh (fast setting) PVC cement.
You can see the cap at the right of the above photo; it’s the piece below the blue PVC cement-stained pipe. The fragments of plastic are the remains of the storage container I placed over the valves to protect them from further misses. (Not successfully.)
I decided to make two improvements when I rebuilt this complex: to add a ball valve before the sprinkler valves, so that I can make repairs without turning off water to the entire house, and to add a third sprinkler valve for a drip system. You can see the ball valve underneath the rightmost valve in the picture below; the new valve is the leftmost.
It took a bit of tweaking to get the joints and valves sealed tight, with one or two connections having to be redone. Once I had the valves watertight and the wiring reconnected, my system testing showed that our Rain8 WLM, which was an X10 wireless-based irrigation control, had suffered a power blow-out as well.
Since the Rain8 WLM had been discontinued, I decided to replace the controller with an OpenSprinkler Pi, using WiFi for wireless access. For the X10-based controller, I had built my own set of irrigation programs for
cooler, which had been moving from shell scripts invoking
flipit driven by
cron(1M) to using Redis for state and eventually to a web server model, but I dropped all of that—for now—in favour of Sprinklers Pi running directly on
sprinkles (the Pi). With the combination of a regular and a seeding schedule, I have equivalent (or better, with the Weather Underground integration) capability to the previous implementation. The new system has been working well.
With the watering infrastructure restored, I did our fall overseeding, three months late, using a mix of low-water grass and white clover, topped with new soil and compost. These guys—mature and immature white-crested swallows (Zonotrichia leucophrys nuttalli)—showed up once the grass seed hit the ground (and walkway). Let’s hope they leave enough seed to grow. (The mature one is the one sporting the white crest with black stripes on his head.)
Weeding by grid
Now that we’ve begun repairing the lawn with new grass, the final phase will be plucking out the crabgrass that dominated one corner. I’m going to work systematically through the lawn using a grid system, plucking out each crabgrass shoot.
There’s about ½” of new soil spread over top to provide new nutrients, but there are also some pretty beaten down bare patches. We’ll see what the spring growth brings.
Assuming I establish some level of control over the crabgrass, I’ll connect a small drip irrigation system to that unused valve and introduce a corresponding third schedule to the Sprinklers Pi configuration. If that goes well, I’ll add a second valve to the front lawn for drip—unless we decide that even a small front lawn is an indulgence during a severe drought. (In which case, maybe I’ll transplant the sod from the front to the back and go drip-only in the front to the citrus trees and oleander.)
Not too far from the office, FreeWheel Brewing has good beer and hearty food. The sausage board is tasty, if one has the appetite, but the hot dog is reliable and well accompanied by a pint. (Half pints available for those meeting-rich afternoons.)
Seasonal Lobster Roll, New England Lobster Market & Eatery, originally uploaded by schahn.
We drove farther than average to visit the New England Lobster Market & Eatery [Yelp], but the pleasant outdoor space they’ve created a hundred yards or so from the shore of San Francisco Bay combined with a very credible lobster roll made it worthwhile. The potato chips are also excellent.
