Saturday 20 August 2016

Saturday - Did some yard chores.

Worked on the app. Came up with a better approach to the logic, simplified things. The level is working now, though the graphics are a bit rough.

I had a couple of bugs - one was me, just a mistake in the array being used. Duhhh.

The other was a bit more subtle: comparing NSNumbers in an "if" statement.

If you write:

NSNumber * someOtherNumber = [NSNumber numberWithInt:3 ]
for ( NSNumber * someNumber in SomeArray)
{
    if ( someNumber == someOtherNumber ){
            // do something clever
    }
}

and someArray does in fact contain the value "3" it will work. Mostly. But not all the time. Apparently the statement can be interpreted by the computer as something like:

if( 2.999999 == 3 )

on occasion.

What you need to do is compare the NSNumbers with their own operator (yes, you'd expect that automatically given that there is an NSNumber of either side of the equality operator, but OC doesn't do it). If you use:

if ( someNumber isEqualToNumber: someOtherNumber )

you'll get the right answer.

Basic stuff, but it can really mess things up.

Friday 19 August 2016

Friday - Hot.

I waited too long for my walk, and decided it was too hot. No sense in getting heatstroke...

Debugging the logic for the new level.

I was texting with a friends son about school, it starts next week. There is a class being offered Wednesday nights at the community college in C++. I'm tempted, it'd be nice to get some real training in this stuff, but it's also pretty expensive, both units and book. Maybe I'll audit and see what the syllabus looks like.

The library received the third Peculiar Children book, and the last in the Temeraire series, so I went by and picked them up.

Thursday 18 August 2016 Thursday - Hot.

Still grinding away on the new level. It is, as usual, more work than I expected.

Wednesday 17 August 2016

Wednesday - Hot.

R & S are off to San Francisco so I'm house watching for them. Making sure cats, dogs and fish are fed and watered. One of the dog even needs medicine twice a day. No biggie.

A walk in the morning, three miles.

Tuesday 16 August 2016

Tuesday - Hot.

Working on the app. This is a new level of play, so thinking and experimenting with various things.

Monday 15 August 2016

Monday - Hot. Low 100's in the afternoon.

School has started, so from about 7:15am to 8:05am there is a constant flow of traffic.

I took a morning walk, just after 8:00. A dog (probably a pit bull breed of some kind) jumped his fence (I saw him do it) and followed me for about 500', growling, and maneuvering to come up from behind. Sheesh. I should report it, but I understand that PB's are put down almost immediately at the pound, and I'm softhearted.

I did about three miles, with no foot problems.

That was the day's excitement. I worked on the app until after 6:00pm. It was dry and the house stayed relatively cool.

My gardening is a bust this year. Sheryl says it's just been too hot for the buds so there have been a couple of stunted peppers, a couple of cucumbers, and absolutely no tomatoes whatsoever.

Sunday 14 August 2016

Sunday - Hot. In the low 100's.

I did some shopping in the morning, groceries, then small chores around the house and yard.

I put up the new hummingbird feeder. On the box it said "New & Improved!" and I just sort of chuckled and thought "I doubt it - Marketing made them say that!".

But, actually, it IS much improved! The mouth to the glass reservoir is triple the size of the old so it's easy to clean and fill. The feeder base is two parts, so it also can easily be opened and cleaned. The top hanger unscrews, and the glass reservoir below is flat topped, so it will stand upright on it's own for filling.

Too hot to do anything outside, so just worked on the app in the afternoon.
