A few more things have come up since yesterday, so here we go.
First, the pile of accumulated hail is still present, now more than 48 hours after it fell:
Temperatures are in the 7-9 degrees (Celsius) range, so it's cool, but well above freezing. Apparently it was a lot of hail.
Next, I went to school today - despite it being a Saturday, and covered my slab project in white slip. The photo isn't great - they were on the top of the drying rack, well hidden, but you can see them here, sort of:
Those will be white once they are bisque fired. Then I will cover them with a turquoise glaze, I think, which should make them quite pretty. Tentative title is "E.M and J.B. Early Efforts". Someone will work it out. Email me when you think you have it.
After that work was done, I decided I had a few minutes to spare while there, and one of the perks of being an art student is you get a locker which you are allowed to paint. A few weeks ago I covered mine in gesso, to hide the old homage to The X-Files (which was nice, but a bit stale, to be honest). So, today, I turned it into this:
It really stands out now. You can't miss it. And I rather like it. I might need to do another layer over it at some point, but possibly not. Also, for the record, the texture on the front predates me, and I left it there. I kind of like it, actually.
On my way out the door to go home, I noted this:
That's a display cabinet in the central arts courtyard area in which the various art instructors hang shows of the work their students are producing. Down in the lower left, that's my most recent project from design studio. The other works in there are really good, though. Much better than mine, in my opinion. Top right is a sea snake or eel. Middle left is jelly fish. Middle right is a rabbit. Bottom right - unlabeled - is a jumping frog. I think they are all more expressive than mine, but each has its strengths.
And finally, from this morning's dog walk, I have several photos for your consideration:
Each of those shows a bunch of torn up grass. The question for you is, what is doing that? What is ripping up large areas of grass like that?
Before I tell you, I should mention that this started a few weeks ago. The torn up spots started appearing - at random - all over the area we live in. Sometimes they were under trees, sometimes they were out in the open, well away from everything. For several weeks we didn't see what was causing them, and we wondered. Squirrels digging up old nuts, perhaps? Skunks or raccoons digging for grubs?
Anne finally saw the answer, and I saw it as well a couple of weeks later. I was rather surprised, really.
Crows. Yes, crows.
The local crows have can openers where their beaks should be, and we've seen them pulling the grass back to get at something - we're not sure what - beneath. There is a lot of sod in the area, and perhaps that makes it easier to pull it back, even years after it was installed. Or maybe not. Maybe they are just that strong and that determined. Either way, it's crows, and they are prying open people's yards to get at some sort of food. It's quite impressive, in a certain destructive way.
Those are the updates for today. Hope they were fun!

Mysteries Reprise
A while back I wrote a post about three mysteries, things I didn't know the answer to.
After a very brief period of time I had an answer to the first one. It turns out that these lines in the road:
in freeways, as seen here:

Are part of a kind of road repair called a "dowel bar retrofit". It's a way of tying one section of concrete to another so they don't move as cars cross from one to another. I'd seen these for years all over the country and had no clue.
The second mystery to be resolved was a problem with using my USB scanner under Ubuntu Linux. That was fixed with my own continued digging and a reader pointing out a final syntax issue in something I did. The scanner works again, which is the important thing.
And the final mystery is now resolved as well. A series of strange items out off the western coast of Richmond are now identified as "Beacon Piles," and are present to keep ships from running aground. They are unlit, round, orange signs visible from the north and south, looking like this from the back (on land):
(The front sides are painted orange for visibility to ships out in the channel.)
The only question I have remaining about these is why they are where they are. The actual channel is well beyond these beacons, and any ship of significance will run aground long before it gets to them. Still, the contributions of several readers helped definitively identify them, so I can stop pondering them now. (And I am sure they are not radar reflectors, despite many references to them by that name. They are simply visual markers for ships to see in the daylight.)
Much of the conversation about these things took place on Facebook, and while I have all kinds of problems with that platform, it helped in these cases. If you're friends with me there, you can find the back & forth on this in the comments to the post announcing that earlier blog entry.
Also, if you have a burning question needing an answer, consider sharing it with me. Apparently I have more than a few readers who love digging into things, and who know all kinds of stuff. Maybe we can get it answered for you.

Mysteries
This post is going to cover three different mysteries. These are things I have wondered about, and want to know the answers to, but that I have yet to understand.
Anyone who can help me with the answers to any of these things will earn my eternal gratitude, and a link here to their website if desired. Obviously that means I will update the post with new information as it arrives. As with all things, you can reach me if you try, despite comments being off here.
Oh, for all images here, click to see a larger version.
MYSTERY 1 - Strange marks in highway pavement in the USA
SOLVED! SOLVED! SOLVED!
Here's a picture taken on I-5 in Northern CA, on a trip to Vancouver:
MYSTERY 2 - Wood, round, antenna structures west of Richmond, BC
On our regular dog walks along the dyke on the western edge of Richmond, BC, we see odd, round structures, apparently made of wood. There are several of them, well spaced out. Here's one, from afar, and zoomed in. (The zoom'd image is blurry... sorry.)
MYSTERY 3 - The scanner that stopped working in Ubuntu Linux 16.04
SOLVED! SOLVED! SOLVED!
No pictures for this one, I'm afraid, but I wrote it all up in great detail in a post on the Ubuntu Forums here:
https://ubuntuforums.org/showthread.php?t=2369422
In short, I updated my OS and everything works (as far as I know) except the scanner. And the failure mode of the scanner is really, really odd. It's as if the bus ID and device ID that were in use for the scanner in the previous version of the OS were saved somewhere, but after the OS update everything got renumbered. When software to find the scanner is run as a regular user, the scanner cannot be found. When the same software is run as root, it does find the scanner (apparently).
As with the other mysteries, Google has not revealed a solution so far.
And that's it. Fame* and fortune** await the people who help me understand these things. Consider it a challenge, please!

MYSTERY 1 - Strange marks in highway pavement in the USA
SOLVED! SOLVED! SOLVED!
Here's a picture taken on I-5 in Northern CA, on a trip to Vancouver:
Look at the road in front of the car. See those sets of 3 marks on each side, roughly where the wheels of the car go? Those are the mystery. Here's a closeup:
What are those things? Here's what I know so far:
- I have googled quite a bit and been unable to find a search that tells me anything.
- It appears that they happen on expansion joints (or some other linear crack in the road, perpendicular to the direction of travel).
- I have seen them in several states, mostly in I-80, but also (as above) in California on I-5.
- The spacing between groups (in the direction the cars travel on the road) can vary.
- Sometimes there are 2 groups of 4 marks instead of 2 groups of 3. No idea why. But that happens on very different roads. I have never seen groups of 4 & 3 on the same road.
| Mystery 1 has an answer! Readers K and P (possible links still coming) tell me these marks are made as part of a 'dowel bar retrofit', which is a mechanism used to reinforce cracks in highway concrete. Here's a Wikipedia article about the technique. |
MYSTERY 2 - Wood, round, antenna structures west of Richmond, BC
On our regular dog walks along the dyke on the western edge of Richmond, BC, we see odd, round structures, apparently made of wood. There are several of them, well spaced out. Here's one, from afar, and zoomed in. (The zoom'd image is blurry... sorry.)
And here is a shot showing several of these things off to the south:
And finally, here is a captured image from Google Maps, where I have measured the distance between these things. The points on the white line show their locations.
And here's what I know (it's not much):
- They appear to be made of wood, and have no apparent electrical connections.
- They face South West. (Bring up google maps for Richmond, BC, switch to satellite mode, and zoom in to confirm that yourself. You can see them in some detail there.)
- The spacing between them isn't regular. (See map above.)
- They are in a straight line running very close to due North/South, as far as I can tell. (Again, see map above.) It is just possible that they do not run perfectly North/South, but from the level of detail I have, it's hard to know.
- And once more, Google has let me down on finding more details.
That's it. I know nothing more.
| Mystery 2 has been solved. It prompted a lot of discussion on Facebook and in email, and many people participated in the conversation. K suggested these are navigation markers for ships, and looked at some nautical charts but didn't find them specifically. I found them in openseamap.org, but couldn't find the description of the actual things I found. J found the actual information about the chart annotation that resolved it, along with the formal description of the item type - "Daybeacons" - which says: "Generally, daybeacons are unlighted aids used primarily to assist the mariner during daylight hours" and goes on with other information that makes it clear that these things off the coast of Richmond are there to keep ships out of trouble. Thanks to the many people who looked into this and helped find the definitive answer! It was really fun to get it worked out. |

| Mystery 3 has been solved. Without going into too much detail, there was a permissions problem because of changes introduced in Ubuntu Linux between 14.04 LTS and 16.04 LTS. I, personally, got the problem about 95% solved, but thanks to confusing and inaccurate documentation, I missed a bit of syntax that kept it from working. A good friend (John M.) pointed that last issue out, and suddenly everything works again. I think someone at Ubuntu needs a kick in the head for this, but such is life. The scanner works, and that is all that matters for now. Anyone wanting all the details can read this thread: https://ubuntuforums.org/showthread.php?t=2369422 wherein I document the entire mess. |
