CAROL'S BLOG

Blog is short for weblog (weBLOG).
Check here to see the latest information about my site (and, occasionally, about my life in general).
It isn't a conventional blog—it just lets you know what I'm currently working on!

I returned to my local version of MathJax 2.3, since MathJax is discontinuing the CDN on April 30, 2017. At some point, I may upgrade to the newest version of MathJax, but for now, I'll just return to the version I was using before I started loading from the CDN.

Loading crossword puzzle . One moment please.

I'm having trouble with my seeds sprouting and then the seedlings shriveling up and dying. This is evidently called ‘damping off’. Here are two good articles on damping off: Here are things I'll try: Also, I want to keep track of this seed ball youtube video. I might make some and throw them out into the desert, and see what happens!!
Lots of the seed ball videos don't show the results, leading me to wonder if they actually work. However, this seed ball video shows the results, and it also mentions possibly adding some pest deterrents to the seed balls to deter predators once the balls have gotten wet and started to dissolve. They mention these four: red chili pepper, catnip, pennyroyal, and peppermint. They also mention a minimum density of one ball per square foot.

Based on my work with Paul and Ryan, I added a "clear all" button to the Sentence Shuffle activity in Work Problems. They had so much fun choosing names and seeing the names randomly appear!

Because I haven't been there in a while, I zipped up to MathJax yesterday. Good thing that I did! I learned that the MathJax CDN (Content Distribution Network) is shutting down on April 30, 2017. Please spread the word to anyone who might be serving up their math web pages with the MathJax CDN!

My entire web site uses this CDN, so I'll now need a different approach. There may be some downtime while I transition to a new delivery solution over the next few weeks.

Also, I just learned that rabbit droppings are great for both the garden and the compost pile. (By the way, we do have a rabbit right now—and the droppings are small, dry, mess-free and odorless.)

Happy Easter, everyone! I don't want to lose track of this collection of ultra-cute Easter treats!

I added new material to Rate Problems, based on my work with Paul and Ryan.

I plan to go to POWWOW (Produce On Wheels With-Out Waste) tomorrow morning, and get 60 pounds of produce for \$10. This will be my first time (my daughter brought this to my attention)—I'm excited to see how it works!

I thought the email address on my homepage was sufficiently disguised to be spam-proof, but Ray said that spammers could see right through it. So, now, we've created a table containing a mixture of text and graphics to present the email. We'll see how this one works in keeping the junk email down!

I added new material to Multi-Step Conversions, based on my work with Paul and Ryan.

Friday, April 7, 2017
I put Google's reCaptcha on my homepage, to cut down on spam I'm getting from my contact form. We'll see if it works! [Update: It ended up requiring server-side processing, which I don't do. So, I removed my entire contact form and put spam-safe instructions for users to contact me instead.]

I've finished several fabric/cardboard bookshelf dust shields , and I'm pleased with the result. Now that I've made a few, they're quick and easy to make. Again, I'm just using up pieces of fabric from my stash, so they're all different.

I finished modifying the cover for our hauling trailer, so the wind (hopefully) won't be able to get underneath, lift it up, and rip it to pieces. It was massive sewing—about 4-5 hours of steady sewing machine use (because the trailer is BIG). Now my sewing machine is making a horrible noise, although it's still sewing great. Hopefully it just needs a rest! The cover now has four sides with velcro closures. We'll see if it works!

I also started a rock enclosure for a compost pile, and I'm working on getting rid of the pile of sticks in front of the Holiday Trailer. Good exercise day!!

I've finished the web exercises for Partial Fraction Expansion: Linear Factors. These were tough ones! I'm particularly pleased with case 6.

Happy Pi Day, everyone!
WolframAlpha offers this cool Find Your Personal Pi Day.
I start at digit 17,347.
Ray is a lot further in: he has 2,025,366.

I've finished the concept discussion for Partial Fraction Expansion: Linear Factors. It feels good to be back doing some math!

I updated my monthly stats for February 2017.

This has been moving month! We gave notice on our rental (Stepping Stone) at the end of January. We were there for 2-1/2 years, from 8/28/14 to 3/1/17. We had a year lease, then a six-month lease, then (highly-expensive) month-to-month rental, each time thinking that ‘Pebble is almost done’. But, it IS now done, and was definitely worth the wait! Awesome things take time!! I LOVE LOVE LOVE it here!!!

So, we've been moving out, cleaning, and moving in all month. I started by thoroughly cleaning the Holiday Trailer (our ‘Pebble overflow area’) while Ray finished some final items on Pebble. Then, I thoroughly cleaned Pebble (it wasn't bad—Ray had been cleaning regularly) and started moving in. Bring a car-load, settle those items in, repeat. The only big items here are the dining room table, our mattress, a twin mattress, the double rocker, and the electronic keyboard. The final move-out inspection at Stepping Stone was today (yesterday was a no-show). Stepping Stone is clean, clean, clean—I keep places very clean all the time, so ‘move-out’ cleaning is really fine-tuning. We should get the entire security deposit back (hooray).

I still have lots of things to do to feel fully settled in, so I probably won't start back on math for a few more weeks. Currently, I'm making cardboard/fabric shelf liners (using up lots of odds-and-ends fabric).

I updated my monthly stats for January 2017, and did the archive for 2016.

I also did my blog archive for 2016.

And, I completely finished my Georgetown quilt! The batting was attached to each square individually, using a ‘bramble’ pattern on my embroidery machine. At the end, I just did straight-line stitching to frame the squares and hold the front/batting/backing together.

I had a lot of trouble with puckering when trying to quilt my Georgetown quilt. I suspect part of the issue is that because it is composed of so many tiny pieces, there is some irregularity from square-to-square. Finally came up with a successful technique; I'll document it here for future reference. This is for a block quilt, so I just used straight-line stitching to hold the layers together. Tuesday, January 31, 2017
I used this youtube video to make the mitered corners on my Georgetown quilt. Came out great! I want to keep track of this link. Also, this is a great resource for binding a quilt. I've used the continuous strip binding, and sewing it to the back of the quilt with no hand sewing.

We did it!  We gave our official one-month notice on our rental home in Rancho Sahuarita.  As of March 1, 2017, we will be ‘one house down’—no longer renting Stepping Stone!! The move is on!! Ray has been working around-the-clock (with only like 4 hours sleep) to finish things up in Pebble. He's a Superman!! HOORAY!!!!!

Also, I finished the last quilt square on my Georgetown quilt; now, the border and backing. It's sized for our on-the-floor-of-the-loft bed in Pebble. I'm pushing to finish it here in Stepping Stone—since Pebble is so small, it would be difficult to work on something this big there.

I've finished the exercises for Partial Fraction Expansion/Decomposition (PFE).

Wednesday, January 18, 2017
I've expanded the concept discussion for Partial Fraction Expansion/Decomposition (PFE), and finished the first 18 exercises. Lots more to go, though!

Friday, January 13, 2017
I've finished the concept discussion for Partial Fraction Expansion/Decomposition (PFE).

I'm making homemade appliance covers for the appliances I'll keep out on the counter in Pebble. Finished the Instant Pot and Magic Bullet covers; now working on my breadmaker cover.

Thursday, January 12, 2017
I've started the concept discussion for a new section, Partial Fraction Expansion/Decomposition (PFE).

I want to keep track of this acceptance speech by Meryl Streep. I've always loved and respected her, and this is why.

I updated my monthly stats for December.

I changed the formatting for the three approaches, to simplify the presentation in Vector Application: Forces Acting On an Object in Equilibrium.

I used an old bedspread to make a draw-string table cover, to protect our Amish-made wood table as we move and settle into Pebble.

I'm extending my ‘boxes system’ to include all of my non-closet-hanging clothes (again, in preparation for the move into Pebble).

I've finished three of eight rows of my Georgetown quilt (which will be a bedspread for Ray/Carol's bed in Pebble). It's made almost entirely from my stash of scraps! I'm quilting-as-I-go: make a square, place batting on the back, join with the ‘bramble’ pattern on my embroidery machine.

After seventeen years, I sent out a Christmas letter! It was a wonderful opportunity to contact many people from my earlier life.

Happy New Year, everyone! 2017 is a prime number!

I haven't used my Speedy Stitcher Sewing Awl for a long time, so I need to remember how it works. Here are some good youtube videos: Blog Archive, 2016
