## CAROL'S BLOGBlog 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!
Tuesday, June 15, 2016Ron/Peter discovered that when you put in a BIG number whe creating a worksheet, it can lock up the computer. So, I'm putting in a max of 100 for worksheets. If you put in a number greater than 100, an alert box says that ‘your worksheet will have 100 problems’ and then does that. I've gone back to the 50 files already updated and put in this new feature; I'll put it in with my other updates as I move forward. Tuesday, June 14, 2016I've finished the exercises for Introduction to Vectors. Monday, June 13, 2016I put a blocking cookie on my
Number Line Population statscounter, so my own visits won't be counted. Then, I reset
the counter to zero.Saturday, June 11, 2016I modified the worksheet on Finding Least Common Multiples so that it won't give any repeat problems. Kept the same variability as the online problems (so they're quite easy), and limited the max number to 20, so it wouldn't have to work too hard to create unique problems. Friday, June 10, 2016A pillow cover from an old shirt, I love it! Thursday, June 9, 2016I've created a Number Line Population as a donation incentive—so much fun! Opened it up (for free) to my Facebook friends to start populating the number line, and there has been very positive feedback. Hooray! I had to download the newest version of JSXGraph in order to use ‘over’ for a hovering-over-a-point action. Finished all the squares with external fonts for my ‘embroidery machine sampler’ quilt. Now, I'm doing the squares with the built-in fonts. Got five more updates done in my Algebra Pinball chart. I've got the concept discussion done for Introduction to Vectors. Productive day! Tuesday, June 7, 2016I'm keeping track of my updates via the middle-school Algebra Pinball chart. As I put in the concept question feature (and other tweaks) I add the exercise to this chart. Trying to do about 5/day. I've got 30 done so far. I want to keep track of Doodle for things like: Who will bring a dinner to a sick church member on what night? It's easy and free! Sunday, June 5, 2016I've been on ‘kitty duty’ for five days. Kitty Mommy and Daddy (AKA Julia and Tony) get home tonight! Saturday, June 4, 2016Came across this website, www.pdffiller.com. I saved one of my randomly-generated worksheets to my desktop, then brought it into pdffiller—then the answers can be typed in. This might be useful to some people using my site. Friday, June 3, 2016I created a blank Algebra Pinball table to make it easy for people to keep track of their own progress. I put links to it from my main Table of Contents, and from both of the existing Algebra Pinball pages. Thursday, June 2, 2016I updated the Multiplication algebra pinball sheet to include info about which numbers were used, and whether variables were used or not. I've scheduled an Algebra Pinball Ice Cream Party for Saturday, June 11th, at 3PM, for locals (via Facebook): the admission is one Algebra Pinball timing sheet that beats Peter/Ron's time! We'll see if I get any takers! I'm managing to stay a few lessons ahead of Peter/Ron in updating my lessons! Wednesday, June 1, 2016I updated my monthly stats for May. Tuesday, May 31, 2016I've updated Expressions versus Sentences to include the available/mastered/in progress concept question feature. I also changed some text: -
Jump right to the exercises!
See the best Algebra Pinball time. The concepts for this exercise are summarized below. For a complete discussion, read the text.
was replaced by:
PRACTICE (online exercises and printable worksheets) ... ... and lots MORE PRACTICE! This page gives an in-a-nutshell discussion of the concepts. For a more thorough discussion, read the text. - I inserted the word ‘PRINTABLE’ on the worksheet buttons
- After ‘Want to time yourself?’ I inserted a link
‘(See a
*blazing fast*time at Algebra Pinball.)
I also changed the top text on my main Algebra Pinball page, and I changed ‘cross-dressing’ to ‘dress-wearing’ on my homepage. Monday, May 30, 2016I've been gone for several days to attend a niece's wedding in Utah. The day after the wedding, lots of the family got together to hike to Stewart Falls. It took a while to locate the trailhead, since their posted info was wrong. Once that was figured out, it was a beautiful hike. Tuesday, May 24, 2016Peter/Ron and I uploaded several pages for the summer project: - the main table of contents now includes new entries for:
- We put in a place-holder for the page that Peter/Ron will create that documents their progress through the curriculum.
<input>
tag and adjacent word(s) inside a <label></label> container. Thanks, Peter and Ron, for this
great suggestion! I'll update my relevant exercises as we go through
the curriculum.
Monday, May 23, 2016Today was the first meeting with Peter and Ron (both entering 7th grade), to talk about a summer math project. It went great—they think it will be lots of fun. My goals for them: - have fun
- deepen their understanding of existing math, and learn lots of new math
- learn about web design while creating their own web pages that document their progress through Tree of Math
- Get feedback on what works and doesn't work. I believe that my curriculum, starting with Algebra I, is accessible to self-motivated middle-schoolers. Peter/Ron will go through the lessons, and help me locate places that could use improvement.
- Peter/Ron will put up Algebra Pinball scores, so other users can have a sense of what people their age are able to do.
- I want parents/teachers world-wide to say to their children/students: ‘Go visit Peter and Ron online—they'll guide you through Tree of Math’!
Sunday, May 22, 2016Here's a technique for a ‘dowel pocket’ for hanging a mini-quilt on a wall. Also, here's a sleeve technique (which is good for bigger quilts). My Aunt Martha sent me a huge bag of scraps! Together with
the ones I got at a recent tag sale, I am now extremely well-stocked!
Here are some scrap project ideas I want to keep track of:
- crazy square block
- turning fabric scraps into yardage
- I've got a good variety of leaf dies for my Big Shot, so this pretty leaf design (coaster?) would be beautiful
Saturday, May 21, 2016This is a great
binding tutorial.
I'm using this technique to put the binding on Julia and Tony's
wedding sampler quilt. It's actually going to be finished in time for
their one-year anniversary!!I want to keep track of this fun memory game; a great use for the many fabric scraps that I have! Thursday, May 19, 2016I added this beef and rice casserole to my online recipe collection. It definitely meets my criteria: easy, delicious (a near-10 with Ray), healthful, and inexpensive. Bought bathroom wall tile and paint for Pebble today! (We won't have much that's painted—just a tiny bit in the bathroom, and behind the kitchen appliances.)Wednesday, May 18, 2016I've added two dynamic JSXGraph boards to Calculating Percent Increase and Decrease, to help people visualize percent increase and decrease. This has been my most popular page for years. (We'll see if this change helps or hinders the page popularity!) Thursday, May 12, 2016I've finished Solving Pseudo-Quadratic Equations. I'm really pleased with the variety of equations. Now, a few days of dedicated sewing! Saturday, May 7, 2016Julia and I went to the Tucson Botanical Gardens (their ‘Weird Plants Sale’) for a Mother's Day gift to me! She got me a gorgeous Kelly Griffin aloe hybrid and a homemade pot to put it in, to have on my kitchen window in Pebble. The color and texture is very different and beautiful. She also took me out for sushi for lunch. What a wonderful day! What a wonderful daughter! Friday, May 6, 2016I've added some material to the Quadratic Formula. Realized I didn't have a simple example of actually using the
quadratic formula.And—exciting day—we got Marybelle a car!!! It's a 2002 Honda Accord EX Sedan, in excellent condition. One big thing checked off the to-do list! Thursday, May 5, 2016I've finished the concept discussion for a new section, Solving Pseudo-Quadratic Equations. I thought I had this flower stitch attachment video in an earlier post, but I couldn't find it! Tuesday, May 3, 2016I finished the exercises for Solving Trigonometric Equations. I've loaded all my fonts (almost 50) into AlphaTricks, and adjusted baselines where needed (like dipping ‘y’ beneath the baseline). I'm creating blocks for my ‘sampler quilt’ that illustrate each of these different fonts. It will take a while to finish this, but I'll have a fantastic at-a-glance sampler of what fonts I have available, when I'm done! I've finished three (of seven) of the blocks for Julia and Tony's wedding quilt: the ‘robot’ invitation, the map, and the lego heart. We've decided on three of the four remaining blocks, and also decided to put a multi-colored border around all the blocks, with a black border around the outside edge. Monday, May 2, 2016Julia located this free color-blindness simulator at http://colororacle.org/ to let you see what your site looks like to people with common color vision impairments. Friday, April 29, 2016I added more Fun Facts, so I now have 80. I also now allow the full set of fun facts to appear on the bottom of each of my pages (I was using a subset). I tweaked my header, so the logo and links are vertically-aligned-top instead of middle. I got back late Wednesday night from my three weeks with my Mom in Massachusetts. It was a great trip: lots of double solitaire, snuggling watching movies, good meals together, playing piano, laughs and hugs! Wednesday, April 27, 2016I need to keep track of these links: - Wolfram Mathematica Online (free)
- the Wolfram Language: Fast Introduction for Programmers (free)
- An Elementary Introduction to the Wolfram Language (free)
Tuesday, April 26, 2016I finished the concept discussion in Solving Trigonometric Equations. On to the exercises! Sunday, April 24, 2016I finished Example 4 (using graphical methods to approximate solutions) in Solving Trigonometric Equations. Saturday, April 23, 2016I've made some progress on Solving Trigonometric Equations. Thursday, April 21, 2016I added javascript recursive-sequence-calculating forms to Loans and Investments. Couldn't get WolframAlpha to give me a future value of a recursive sequence, no matter what syntax I tried! Wednesday, April 20, 2016I've started a new section, Solving Trigonometric Equations. There are a bunch of word-press-related files that are continually appearing in my server error files. I briefly experimented with WordPress many years ago, but never used it. I don't want all these errors occurring, so I
uploaded php files with these names, that merely say ‘Who is
accessing this file? Contact me from my homepage, please!’. We'll see
what happens!I want to keep track of these instructions for how to hide/show hidden files (those preceded with a dot, like .htaccess) on MAC OS 10.6.8 (Snow Leopard):
- To call up the Terminal window:
`command-space "terminal" (then enter)` - To SHOW all hidden files:
- In the Terminal window, type:
`defaults write com.apple.finder AppleShowAllFiles TRUE`(then enter)
`killall Finder`(then enter)
- In the Terminal window, type:
- To HIDE all hidden files:
- In the Terminal window, type:
`defaults write com.apple.finder AppleShowAllFiles FALSE`(then enter)
`killall Finder`(then enter)
- In the Terminal window, type:
Tuesday, April 19, 2016I updated TeX Commands Available in MathJax so that it contains all macros through the newest version, MathJax 2.6. I added: `\textsf` ,
`\texttt` ,
`\hfil` ,
`\hfill` ,
`\overparen` ,
`\underparen` Sunday, April 17, 2016I've finished going thru all my pages after the MathJax upgrade! They look amazing, and load unbelievably fast. HOORAY!! There are pages that have some lingering issues if you're using ancient Safari (like me, with version 5.1). Some I fixed, but if they required too weird of a tweak then I chose to leave them broken for this tiny audience (which includes myself). Here are the two main issues that I discovered: - when I use overset/underset constructions in display math, the baselines are often incorrect
- when there is a mix of text and math in a special text phrase (like emphasis, bold, highlighted), every time math is hit it is moved to a new line
In the second case, stuff is readable, just ugly. Saturday, April 16, 2016I changed my ‘Need a Short Break?’ section to include a button to suggest some mathy/nerdy/geeky/fun things to search for at Amazon or Etsy. (A reward for hard work!) Friday, April 15, 2016I found code at Simple Sharing Buttons Generator that allows me to use the nice social icons supplied with my Pen & Pencil template (instead of getting icons directly from Facebook, Twitter, etc.) They seem to work great! I also got share buttons (for Facebook, Twitter, Google +, Tumblr, Pinterest, and LinkedIn) up on all of my lessons! Hopefully, this will make it easier for people to spread the word about my site. I think they look good! Thursday, April 14, 2016I've removed all my website summary statistics and income information. These images/comments are on MAC OS X version 10.6.8, with - Chrome version 49.0.2623.112 (64-bit)
- Firefox version 45.0.1
- Safari version 5.1.10 (6534.59.10)
- baseline issues:
`displaystyle\frac{2}{7} = 0.\overline{285714}`
$\displaystyle\frac{2}{7} = 0.\overline{285714}$

Wednesday, April 13, 2016So far since upgrading MathJax to the CDN, I've checked through all of Geometry, Algebra II, and Calculus; up to lesson 40 in Algebra I; up to lesson 15 in Precalculus. I've checked each lesson in (ancient) Safari, Chrome, and Firefox. Some more ‘ancient Safari’ bugs: - The $\,5\,$ should be on the same line as the $\,4\,$, with the $\,n\,$ and
arrow beneath the $\,5\,$. It renders fine in Chrome and Firefox.
`{}_5P_2 = \overset{\text{2 factors}}{\overbrace{ \underset{\underset{\displaystyle n}{\uparrow}}{5}\cdot 4} }`
$$ {}_5P_2 = \overset{\text{2 factors}}{\overbrace{ \underset{\underset{\displaystyle n}{\uparrow}}{5}\cdot 4} } $$ MathJax rendering in current browser; display mode image: rendering in ancient Safari -
Here, the $\,i^2\,$ should be centered on the summation symbol.
It's fine in inline mode; just breaks in display mode.
It's fine in Chrome and Firefox.
`\sum_{i=1}^{10}\ i^2`
$$\sum_{i=1}^{10}\ i^2$$ MathJax rendering in current browser; display mode image: rendering in ancient Safari Consequently, Summation Notation and Mean, Median, and Mode look horrible (basically unreadable) in ancient Safari. - Not aligned properly in display mode in ancient Safari; fine in Chrome and Firefox:
`\overset{\text{coefficient matrix}}{\overbrace{ \begin{bmatrix} 2 & -3\cr 1 & 7\cr \end{bmatrix}}} \ \underset{\text{variable matrix}}{\underbrace{ \begin{bmatrix} x\cr y \end{bmatrix}}} \ =\ \begin{bmatrix} 5 \cr 4 \end{bmatrix}`
$$ \overset{\text{coefficient matrix}}{\overbrace{ \begin{bmatrix} 2 & -3\cr 1 & 7\cr \end{bmatrix}}} \ \underset{\text{variable matrix}}{\underbrace{ \begin{bmatrix} x\cr y \end{bmatrix}}} \ =\ \begin{bmatrix} 5 \cr 4 \end{bmatrix} $$ MathJax rendering in current browser; display mode image: rendering in ancient Safari
Tuesday, April 12, 2016I FINALLY DID IT!!! At about midnight last night, I changed my entire site over to use the newest version of MathJax from the CDN (Content Distribution Network)!!! This gets rid of the Chrome bug that was affecting almost half of my users—an ugly vertical bar appeared on the right of every bit of math. The pages also load much faster. I had to set display:none; on the MathJax Preview class. In the 'ole days, I had explicit spans with the desired preview before the math, and these
were hanging around after the math was processed with the new version. Other than this, I just changed
a few lines in the javascript that loads my MathJax, and it was done!I can't believe I waited so long to do this. I feared that some little bit of code that I tweaked in the old version might not look perfect with the upgrade—instead, I was living with all
the math looking horrible in Chrome (half of my users). Stupid, stupid, stupid. So far, I've only seen one thing that rendered differently in my very old version of Safari—an extremely complicated underset/underbrace/overbrace construction. It will take me a while to check all my pages. Please contact me (contact form on my homepage) if you notice anything that seems broken. Thanks!I'm removing the GeoGebra pages, since they're no longer reliable in all major browsers. For people using an ancient version of Safari (I have 5.1.10), some of the mathematics is no longer correctly rendered. Here are some of the ‘ancient Safari’ bugs I'm seeing as I check through my pages: -
`(\overbrace{\vphantom{(x+h)^2} x^2 + 2x + 1}^{f(x)})`
There is horizontal space left for the $\,(x+h)^2\,$ (there shouldn't be).
$(\overbrace{\vphantom{(x+h)^2} x^2 + 2x + 1}^{f(x)})$
MathJax rendering in current browser; inline mode
image: rendering in ancient Safari - Inside emphasis, bold, italics, etc., math is being put on a new line:
`<em>this is $\,x^2\,$ and $\,t\,$</em>` yields:
*this is $\,x^2\,$ and $\,t\,$*
MathJax rendering in current browser

Limits are not rendering correctly in display mode:
`\lim_{x\rightarrow c} f(x) = \ell`
$$\lim_{x\rightarrow c} f(x) = \ell$$ MathJax rendering in current browser; display mode
image: rendering in ancient Safari
- Here, there are thinspaces around each $\,x^2\,$:
It's $\,x^2\,$, it's $\,x^2\,$, it's $\,x^2\,$, it's $\,x^2\,$, it's $\,x^2\,$, it's $\,x^2\,$. MathJax rendering in current browser
image: rendering in Chrome and Firefox - Here, there are NO thinspaces around each $x^2$, and everything displays correctly:
It's $x^2$, it's $x^2$, it's $x^2$, it's $x^2$, it's $x^2$, it's $x^2$. MathJax rendering in current browser

Monday, April 11, 2016I finished Inverse Trigonometric Function Problems: All Mixed Up. Now, there are a couple projects I need to finish for my Mom, before starting a new section. Saturday, April 9, 2016I switched both TeX Commands Available in MathJax and its Korean version, to use the newest available stable version of MathJax, via the MathJax Content Distribution Network (CDN). They now work like a dream! Makes me want to update all
my pages to newer versions. However, on my first test, something actually
rendered differently—so I would need to test each of my pages if I do this. This will wait until Ray gets involved; there will be lots of changes made then.
Every time I make a single pass through all my files, it is a tremendous time commitment, since I have so many files!There's a bug with the rendering of $\,\rm\TeX\,$ in Safari; they initially render correctly, but then they break and look horrible. This problem doesn't occur in Chrome or Firefox. Update 4/11/16: the problem is only with very old versions of Safari (pre-version 6; mine is currently 5.1). Good to know! Friday, April 8, 2016Applesauce day! So easy! Mom loves applesauce, and we're almost out. Here's her recipe: - Wash / core / quarter / remove seeds on about 16-24 apples (Macs are good). (Do NOT peel; the skins add color and flavor to the sauce.)
- Put in large pot (about 8 quarts) with about 1 cup water.
- Cook on low heat, stirring and smushing occasionally (with potato masher), for 20-60 minutes (depending on type and hardness of apples). There can still be chunks; apples just need to be soft enough to put through the food mill.
- Put through rotary food mill (this removes peels).
- After putting through food mill, add about 1/2 to 1 tsp cinnamon, if desired.
- Eat, freeze, enjoy!
- Makes about 8 cups applesauce.
much better than the big ugly ad on top.Wednesday, April 6, 2016Trip to Massachusetts to visit my Mom for three weeks, so my sister can get a break from Mom's care. The flights were on time and uneventful—just the way I like them! We actually got pretzels on the flights (after no snacks on flights for years). Goals for this trip (besides lots of snuggle time with Mom): get Jean's room ready for Marybelle to come and live with Mom; make lots of progress on Precalculus. Tuesday, April 5, 2016I've gotten a bunch more problems done on Inverse Trigonometric Function Problems: All Mixed Up. Finally back to content! I'm testing a small AdSense ad in the box beneath my search box, together
with a marquee to get a daily message to my users. Right now, it's primarily
in the Precalculus lessons. I'll see if I get any negative feedback—I
certainly don't want to annoy my users!Sunday, April 3, 2016After all this time, I finally updated all my Algebra I pdf files to get rid of the fishcaro@crosswinds.net and to put
in my new name instead of Carol J.V. Fisher. I was
worried that people were finding one of these pdf pages in an
internet search, and then never being able to find me! Big job done!
Hooray! Also, two extended family members came over today and
mentioned that they had visited my site, and they were like ‘Wow!’ After about 17 years of working on this, I've rarely had such an enthusiastic
response—so I'm hoping this is a sign of good things to come!Saturday, April 2, 2016Ah hah! An answer to my question about the image tag inside the Amazon affiliate links! I updated my monthly stats and website income for March. Friday, April 1, 2016I've spent the last couple days fixing broken links on my site. I have so much old stuff that I no longer maintain, that it sometimes feels out-of-control. I want to start a fresh new domain, with JUST the lessons!! I was accepted into the Etsy Affiliate program, so now users can support my work by shopping either Amazon or Etsy. Thursday, March 31, 2016I went through my entire main Table of Contents, updating all the pages (and sub-pages) with the new site style. This was a lot of work! Now, most of my site should have the same look-and-feel. I'm sure I'll discover pages that have been missed in the coming months, but I think I've hit the majority. I also deleted all the old versions of my web pages from the server. (Many lessons had a duplicate version with OLD appended at the end of the name.) Now, I can get back to my Precalculus course! I also created a custom 404 Not Found page. Now, if someone goes to a page on my site that isn't there, they'll get this page, asking them to please notify me of the error. My most-requested file that wasn't found for March was apple-touch-icon.png. There were 1687 requests, each of which returned a 404 error. I researched and discovered that this file is looked for when people bookmark your page from an Apple device—so this is a good thing! I've now got a file in place.
Tuesday, March 29, 2016I've cleaned up all my footers, replacing them with a simple common footer throughout, that contains only my copyright info and terms of use link. I've also cleaned up a bunch of other pages (including this one!) that had miscellaneous headers and footers, giving a more consistent look-and-feel to my site. Finally, I've re-done all my course tables of content, to give them a more consistent look. I've consolidated, winnowed, checked, and moved my ‘Fun Stuff’ links into a separate file, available from my main table of contents. Busy day! Monday, March 28, 2016Ray fixed the email problem for my homepage. He inserted code so that, when I get the email, the email return address is inserted as text at the end of the message. (Crosswinds was over-writing the email address with their own address, evidently due to security issues.) Ray also put a re-direct from treeofmath.org to my new homepage. Ray is amazing!! Here's a machine-pieced hexagon quilt that I want to keep track of. Another machine-pieced hexagon quilt. Sunday, March 27, 2016Happy Easter, everyone! I got a new testimonial up—a beautiful email from a former student at Miss Hall's School. (What an Easter gift to me!) I want to keep track of these die-cutting videos for quilting. Saturday, March 26, 2016I've now got five slides in the opening slideshow for my new homepage. I've spent hours trying to figure out how to guarantee that the first image (the cat on the swing) loads first when my page is first visited—but haven't been successful. Sometimes it does, sometimes it doesn't. (Yes, I've cleared my cache many, many, many times this morning.) I've also tweaked my ‘support my site’ display, adding a thank-you link (with a fun color-changing button). And, I've applied for the Etsy Affiliate program (similar to the Amazon Affiliate program); it will likely take a few days to hear back from them. I want to keep track of Jet Anywhere. I could have bought my Orbitz plane tickets thru them, and gotten back 5.6% in JetCash to use toward future purchases. Okay, now I need to check both retailmenot.com AND Jet Anywhere before I buy anything online!! Friday, March 25, 2016I replaced the text-only links with image links, in the ‘Lessons’ section of my new homepage. There are 18 images; when they were full-size (about 1Mb each), the page was way too slow to load. So, I imported them into Pixelmator and exported them for the web (reducing the quality a bit) to cut them each down to about 350Kb. Still too slow, so I removed the Language of Math links (added that to the ‘More’ section). The lesson images add lots of interest, so I think it's worth a bit slower load.I've also taken off AdSense, and replaced it with Amazon. Now, the tops of the pages look much cleaner and more professional. We'll see if the Amazon revenue will increase and make up for lost AdSense income. Wednesday, March 23, 2016I added CAMT 2015 to my online vita. My new homepage is up!! I'm excited!! This has been a long time coming!! Sunday, March 20, 2016Big website change! I changed the background color from the green (that I love, but I think the rest of the world doesn't) to colors that will appear in our new (eventual) website design. Makes it a bit more mainstream! Thursday, March 17, 2016I'm in Massachusetts for a week with Marybelle, visiting my sister and Mom. I added a KenKen link to the Algebra I Table of Contents (‘Fun Stuff’ column). Saturday, March 12, 2016I started my next-to-last section in trigonometry: Inverse Trigonometric Function Problems: All Mixed Up. I've also started the third square in Julia and Tony's memento wedding quilt—the map. I can't finish either the robots or the map until I get my embroidery machine back from the repair shop! I had forgotten how to use my needle threader that I keep velcroed to my machine! I was having trouble with some of the thicker threads, and this really helps. Wednesday, March 9, 2016I got my cornbread recipe up for Friday's cooking/driving date with Marybelle! Tuesday, March 8, 2016I finished the exercises for the arctangent section. I'm getting close to being done with trigonometry!! I broke my embroidery machine, and it won't be ready for pick-up until the end of March. Likely I've (unknowingly) tortured it over the past three weeks, since I'm new to embroidery machines. So, fewer distractions for a bit here! Saturday, March 5, 2016I finally finished going through all the embroidery files that I was given with my Janome 350E! I had to re-organize, re-group, give meaningful names. I've spent mega-hours on this. There are many that I'll likely never use, but a bunch are good. Glad to know what I have, though! I'm making a ‘sampler quilt’ with lots of my favorites (and ones that I've purchased). Bethany got a new rat, so she can breed again! The two major pet store chains stopped carrying rats, but we found one at Tropical Kingdom on Prince Street in Tucson. The man who works with the rats in the back is so nice, and Bethany got a handsome happy rat! Thursday, March 3, 2016I finished the concept discussion for the arctangent section. Seeing all the yellow highlighting (press the ‘see changes’ button) makes me realize why it took me so long, even though this wasn't a ‘from scratch’ section!Wednesday, March 2, 2016I updated my monthly stats and website income for both January and February. Don't know how January got forgotten! I also archived 2015. I'm making good progress on the arctangent section. Monday, February 29, 2016These really cute paper monster and owl corner bookmarks were posted on Facebook, and I want to keep track of them. Seems like a fun, practical project for a rainy day with (possibly future) grandkid(s)! This is just one of many fun crafts from Red Ted Art. I'm starting the arctangent section. Since it's basically a copy of the arcsine section, with appropriate changes, Ray suggested a button that users can click to see all the changes highlighted. I figured out how to do this today using getElementsByClassName . The default background-color for a span is ‘transparent’ (needed to turn off the highlighting).
Saturday, February 27, 2016I added an in-section exercise (at the top) to Addition of Signed Numbers. It was conceptualized by Robert Fant, Technology Integration Enthusiast. Robert was kind enough to send me his code, and give me permission to use it on my site—I then altered the concept a bit and added some functionality. Robert does so much for his students—they are so lucky to have him as a teacher! After about four years, we finally got family photos taken (by
Melony Hall Photography in Sahuarita, Arizona—she was great). Then, I tested out
some different online photo developing places, and have purchased a variety of
inexpensive frames. Want to keep track of my preferences here:- ONLINE PHOTO DEVELOPING:
Mpix: their prints were a bit more expensive than Snapfish, but (in my opinion) definitely worth the extra money. The Mpix prints had better color, and the weight and feel of the photo paper was much more desirable. - MAGNETIC/ACRYLIC PHOTO FRAMES:
I ordered three different kinds online from Amazon, and bought two kinds from Walmart. All were for holding a 4in x 6in print horizontally (i.e., positioned with the long side left/right, the short side up/down).**MY FAVORITE #1** Walmart, Mainstays rigid acrylic, for table display. Only 94¢ each (I made several trips, buying them out each time). You remove a protective film and a paper insert; photo slides in effortlessly. This and the other Walmart frame below are my favorites—most economical and easiest-to-use. Walmart ‘beat out’ Amazon on this particular item.
Also, both of the Mainstay frames are borderless, which I like. The three more expensive (Amazon) ones end up with a narrow white border around the picture, which I don't like.**MY FAVORITE #2** Walmart, Mainstays magnetic photo frame (rigid acrylic). Only 98¢ each. You rip open the plastic bag and remove a plastic insert from the frame; again photo slides in effortlessly. Has a small magnet centered in the back, which is more than enough to hold it securely to the refrigerator. I prefer this to any of the full-magnetic-backing flexible (not rigid) frames below (all of which were more expensive).- Magtech white magnetic photo pockets, set of 10; full magnetic backing; final cost \$1.20 each; ordered on Amazon. The two short sides are open; photo is a bit easier to slide in than the two (more expensive) kinds below.
- Magnetic photo sleeves by Regent Products Corp., comes in set of two, full magnetic backing; flexible (not rigid); final cost \$1.50 each; ordered on Amazon. Only one (long) side has an opening; a bit tricky to get photo in. Feels sturdier and higher-quality than the (more expensive) one below.
- Freez-a-Frame magnetic photo pockets, comes in set of five, full magnetic backing; flexible (not rigid); final cost \$1.85 each; ordered on Amazon. Only one (long) side has an opening; a bit tricky to get photo in.
Wednesday, February 23, 2016I finished the web exercises for Inverse Trigonometric Function: Arccosine. (It wasn't enough work to have taken a week, but I've been distracted with my incredible new embroidery machine!) On to the arctangent! Wednesday, February 17, 2016I got a Janome 350E Memory Craft Embroidery machine! I need one for Julia and Tony's wedding quilt. It retails for \$1999; I saw it new on Amazon for \$1199, and I got it used on Craigslist (in great shape, with lots of extras) for \$750! She recommend the free Wilcom software (TrueSizer) to be able to see and work with the embroidery files (which I haven't yet worked with). While watching the instructional DVD that came with the machine, I made an unfortunate mistake. I was going through the bobbin-area-cleaning process, and after cleaning with the provided lint brush, I noticed that lint seemed to be stuck inside the hole beneath where the bobbin sits. I couldn't get it dislodged, so I got out tweezers to gently pull it out—and immediately realized my goof. Ends up it's an oil wick (it pulled up like a thick cord), and it's supposed to be there.Figuring I had just made a very expensive mistake, I was distraught. An internet search (eventually) turned up someone else who had made the same mistake, and who said the lady at the quilt shop quickly fixed it (but didn't say how). I
was lucky enough to have a wonderful service man at Cathey's Sew and Vac in Tucson who told me over the phone how to fix it—just poke it back down with a long narrow object, and it will be fine!
I also mentioned that a little ‘ball’ of a wax-like substance had come out (like a wax plug), and he said that was likely just dried oil, and to discard it. I did what he said, and my machine is working perfectly!!
Thank you, thank you,
thank you to this kind person who saved me lots of money and turned me into a
future-loyal-customer of Cathey's when I do need repairs!!Moral of the story: DON'T TRY TO CLEAN WHAT LOOKS LIKE LINT IN THE HOLE
BENEATH THE BOBBIN!!! It's actually an oil wick, and it's supposed to be there!
Tuesday, February 16, 2016I finished the concept discussion for Inverse Trigonometric Function: Arccosine. Tweaking the graphics still took a reasonable amount of time, but definitely not as long as first time around! Saturday, February 13, 2016My newest section, Inverse Trigonometric Function: Arccosine, should emerge quickly, since it's just a copy of the arcsine section with appropriate changes. Hopefully just a few days (instead of a few weeks)! Friday, February 12, 2016Hooray! Finally done with Inverse Trigonometric Function: Arcsine. There are 43 different problem types; no teaching-to-the-test when using my materials! Thursday, February 11, 2016I've finished thirty problem types for Inverse Trigonometric Function: Arcsine, and still have lots to go!! Saturday, February 6, 2016I'm putting some recipes and cooking tips on the web; Marybelle and I will be getting together about once each week to start to create a ‘repertoire’ of meals she can make. Thursday, February 4, 2016Finished the concept discussion for Inverse Trigonometric Function: Arcsine. On to the web exercises. I'll have near-identical sections for arccosine and arctangent; then, a lesson with a wide variety of problems that incorporates all three inverse trigonometric functions. Wednesday, February 3, 2016More good progress on Inverse Trigonometric Function: Arcsine. Getting close to being done with the concept discussion! The graphics are taking me a long time to get just right.Monday, February 1, 2016My daughter Julia does a lot of aerial silks at the Circus Academy of Tucson. It's located at 400 W Speedway Blvd; the NW Corner of Speedway and Main. Me, Ray, and Bethany all tried it out—and both Ray and Bethany loved it!! I archived my 2015 blog. Saturday, January 30, 2016More good progress on Inverse Trigonometric Function: Arcsine. Friday, January 29, 2016I'm beginning to be pleased with the concept discussion for Inverse Trigonometric Function: Arcsine. There will be near-identical sections for the arccosine and the arctangent, so it's worth my taking the time to get it right! Tuesday, January 26, 2016Some of these unconventional binder-clip uses are fantastic! I've finally started the concept discussion for a new web exercise: Inverse Trigonometric Function: Arcsine. Wednesday, January 20, 2016I added a sample annotated verse-by-verse Book of Mormon (with exercises) to my things Spiritual page. I had thought about starting this project in 2011 and had come up with this potential format. I may never actually take on this project (it would likely take me decades); but I definitely won't attack it until I'm done with Precalculus (and likely Calculus). But, I didn't want to lose the work I had done. Someone else might want to take on this project!I've been learning Spanish. I've created some online Spanish practice for myself! Wednesday, January 13, 2016I've finally finished the web exercises for Trying to ‘Undo’ Trigonometric Functions. With the busyness of my month in Massachusetts and the holiday season, it took me a month to get this section done. Phew! Tuesday, January 12, 2016This is great: Amazon Shopping Tips There are many of these tips that I didn't know! Saturday, January 2, 2016Happy New Year, everyone! May 2016 be a good one for all. I updated my monthly stats and website income for December, and for all of 2015.
