Saturday - Roasting hot and humid in
the morning. I futzed around in the garage, getting out the laser level
and measuring things. The question is: how many shelfves should I use?
I can put a shelf every 16", that's what the store bought metal units
do. I can put them every 12", which is really enough room for most
stuff: bottles, cans, storage boxes, etc. I can mix it up, 16" on the
bottom, 12" on the top, or even put a 24" or 30" space at the bottom
for large items. Decisions.
Anyway, about 10:30am some friends called needing my help in installing some C compilers for courses coming up.
showered, went over, and installed Xcode (free) and showed them how to
do ANSI C rather than Objective-C on their Mac Pro.
we started the download and install of Visual Studio Express 2013
(free) onto their Windows laptop, so that there'd be a resource when
they're on the road. That took forever,
so we went down to the Antelope Valley Mall and had a late lunch /
early dinner at The Yard House. Really good burgers and a huge beer
selection, including on tap. When we got back it had installed, and we
fooled around for a while trying to get it to compile plain C. It
really, really, wanted to compile C++, and we never did get the
compiler to work properly. I know that I did it myself years ago, 2005
or thereabouts; so either they've broken it for C completely (hard to
believe) or they've just hidden the build options so well that I can't
I'll use my google-fu, but if it's incredibly hard we
can just delete the visual studio and use any one of dozens of
perfectly good compilers available for free. I thought the Microsoft
option might be easiest, but I've already been proved wrong there...
We were going to go for a walk about 7pm, but I'd developed a nasty headache, so I just went home and rested instead.
- Hot and Yucky, again. I had things to do in the morning, so not much
got done on the garage shelf. I did find my dado blades, and I also
remembered that I have a laser lever, which will help.
on the app for most of the day. I 'objectified' a part of the more
spaghetti-ish section, and it seems to run - except that the views no
longer show up on the screen! Also the debugger is broken - it tells me
that I have a memory leak but the symbols aren't found. Huh? Isn't that the point of a debugger?
Telling me the hex code of an address in memory isn't much use on a
four core multi threaded machine. Looking around on the net there are
various fixes to make the symbols display (stand on your head while
whistling 'Dixie' backwards stuff), but, you know, WTH Apple? WTH?
Suzy, venturing a good 20' from the patio, watching birds in the planter under the fruit trees.
Thursday 31 July
- Very Hot. I think it was officially 104F, but near the house it was
probably more like 110F. It was definitely a 2 a/c day - the humidity
was in the high teens which meant the swamp coolers weren't working at
I spent several hours repairing the radial arm saw. For some reason the wooden table was gone. I found a 2x6, a 1x3, and a nice piece of finished plywood that was almost big enough for the main table. I had another piece of plywood that was
big enough but rather rough and (after examination) kind of warped.
Eventually I went with the first piece of wood, and added a 1x2 to make
it fit. I had to look at the manual, the plywood bit is fastened down,
and then you can rearrange the other two (3 now!) bits to suit
yourself. So I drilled and used four countersunk 1/4x20 carriage bolts
to fasten the plywood down, then added the other bits, and cut them to
size. (I'm not actually happy with the bit of 1x6, it's a bit warped.)
admiring the table top for a while I realized I'd put the rough edge of
the 2x2.5' table top against the fence. Sigh. I'd seen the rough edge
on laying things out originally and just spaced on my mental note to
orient the wood using the other edge. The bolt pattern
isn't symmetrical, so it'll look terrible if I try reversing it.
For now it's fine, only out about 1/16".
I then adjusted the saw
so that it made a nice perpendicular cut to the fence. I still need to
adjust the indicator, and then adjust the heel and the planarity to the
table, and cut the 45 degree groves for beveling, but at least I can
make fairly quick cuts now. This is nice because my Skilsaw has issues,
and the table saw motor doesn't work.
I am now wondering: what I
did with the dado blades? I think they're in the garage, but I'm not
sure. They aren't really needed now, I'm going to use particle wood
shelfs and 2x2's as shelf supports, rather than simple pine in grooves
(I have lots of particle wood and 2x2's), but I think I had them at one time.
friend Can called from Panera Bread, asking if I wanted some nice
chicken soup for lunch. Yes! And she brought frozen yogurt with her. We
talked for a few minutes, but it was the kids nap time so she couldn't
stay long. She is taking 'C' at the local JC this fall, and asked about
compilers. She has a Mac with Xcode, so there's a C compiler there -
Objective-C is a superset of C, and she can get C with Visual Studio
for free on her Windows laptop as well I believe.
In the afternoon I worked on the app, playing around with the 'Instruments'
in Xcode, profiling the code and looking for allocation issues and
memory leaks. Right now there is apparently about 200MB of leaks per
turn, which means the app dies after about 15 tries. That's so huge
that I obviously did something really wrong, but what? The single
biggest array in the code is 400 integer elements, which would only be
in the kilobyte range...
Wednesday 30 July
Wednesday - Did a bit of yard work in
the morning, various small things. It's getting hot, and is supposed to
get even hotter tomorrow.
Working away on the garage, in the
cooler morning hours (somewhat curtailed by letting the cats roam,
supervised, for an hour after breakfast). I moved various bits of stuff
to the point where I could get to my lumber stashed and fetched down a
couple of dry 1x12's. This took rather longer than it should have, as I
needed a place to put stuff and had to clear room for it.
Working away on the app in the afternoon again. Not too exciting there...
Talked to S
a bit about the Sudoku app. The Sudoku is just the McGuffin, the point
of the app is to get kids to understand certain basic reasoning skills
that many autistic kids lack. Everyone harps, S says, on "matching" tasks in educational software, but there's a lot more that's needed.
Tuesday 29 July June
- Hot, humid, overcast. Yuck.
a bit of yard work, trimming shrubs in the front and a bit of weed
whacking and vegetable fertilizing in the back. It was too unpleasant
to work in the garage, I'll just wait on that.
Did some work on the app too, mostly just cleaning up and trying to modularize and objectify the code. Not very exciting.
- Disgustingly humid in the morning. I was doing a bit of yard work and yuck...
I had lunch with S and K and discussed the next app, probably a 'latin squares' based training aid. We were calling it Sudoku, but really it isn't...
Then back to the house and and app work. I want to 'objectify' the code a bit more, right now it's still pretty procedural...
- Not much to say, just another Sunday morning. Oatmeal and coffee
while watching the cats wander the yard. Suzy has now ventured a full
six feet from the patio....
did go down to Ojai with friends to visit their parents. It was a nice
outing, they are always fun and pleasant to be around, and we had a
nice visit and lunch before heading back to Lancaster.
They are enjoying their ebooks. I mentioned that there is a Kindle App for the Nook and iPad, and a Nook App for the iPad.
Putting a Nook App on the Kindle can be done, but it's kind of a 'side load' thing, not really supported. Too bad.
is a iPad App for the Kindle, but you can only use it to read stuff in
iBook format that you bought from Amazon. I guess stuff that you bought
at Apple won't run. I imagine the same is true for the iBook app on the
Nook (a droid is a droid) though I haven't found a source specifically

Book #22 (As Maxwell Smart might say, I missed finishing this on Saturday by that much...) was The Dead in their Vaulted Arches (Flavia de Luce #6), by Alan Bradley.
last book was kind of a cliffhanger: we read at the end that Flavia's
long lost mother is returning home. In this book we learn that actually
it's her body
that's being returned, finally found after being frozen in a Tibetan
glacier for ten years. This is my least favorite of all the books, it's
more of an introduction to what the author plans with the rest of the
series I guess, and the English manor mystery stuff takes a decidedly
back seat to a bunch of other stuff.
But one bit had me hooked...Flavia decides that she's going to open her mothers sealed coffin and try to resuscitate her ten year old corpse! Gahhhhh. It doesn't happen, but it was pretty suspenseful there for a bit.
