Let’s imagine the variable $v0 is not defined, and therefore false from Perl’s point of view.
$v0 ? print ‘defined’ : print ‘not defined’
will output not defined.
a?b:c is known as the ternary operator. If a is true, then b happens; else, c.Source:
Jack of Oracle Tutoring by Jack and Diane, Campbell River, BC.In my Feb 14 post I use the word hilarities, which the spell-checker doesn’t like, though it’s happy with hilarity. So, is the word hilarities valid?
A source online describes hilarity as “a situation of humour.” Well, then, two different situations of humour are two hilarities, aren’t they?
PS: The spell checker doesn’t like humour, either:)

Jack of Oracle Tutoring by Jack and Diane, Campbell River, BC.On February 8 I talk about red velvet cake and my decision to make it.
My wife arrived as I was blending the icing. Seeing the cakes cooling on the wire racks, she naturally asked if I wanted her help. I happily agreed for her to ice the cake, but watched her do so, looking for hints.
The cake turned out well, but was better on the second day than the first. Moisture from the icing penetrated the cake, while the icing itself seemed to get lighter as a result, becoming like whipped cream. The cake, after a day, reminded me of strawberry shortcake.
It’s long gone now. The question: If I make another one, will I use the same recipe, or experiment? This recipe turned out fine:)

The word relatable is listed by a couple of authorities I’ve checked. Yet, the spell checker in one of the apps I use doesn’t like it. I wonder who finds this situation relatable?

Who knew?

Jack of Oracle Tutoring by Jack and Diane, Campbell River, BC.I’ve never heard of anyone’s waxing a snow shovel. Yet, this morning, the idea came to me.
I was using a deep shovel. When I would throw the snow, about 20% remained embedded within the shovel: it wouldn’t clear. I wondered what to do.
I recalled a story told me many years ago. An outdoorsman came upon some skis, so decided to try them. He was used to waxing toboggans, so did so to the skis.
He found the skis moved far too easily: he quickly gained unsafe speed on the hill. Not being a skier, he couldn’t control it properly and went down. Next he scraped the wax from the skis: much better.
Would wax work as well on the shovel? I dried it then rubbed an old candle in its bed. Trying it out, I noticed an absolute difference: the snow didn’t stick.
The wax needed re-applying every few minutes, yet it helped a lot.
Best of luck with your snow-clearing:)

@arr=map {‘and a ‘.$_} (1,2,3,4);
yields

Jack of Oracle Tutoring by Jack and Diane, Campbell River, BC.In PHP, register_globals, when set to 1 (or on), could allow variables to be created and set from within web requests. In particular, if a variable was uninitialized in a function on the server, it could be initialized with a compromising value from a request.
| PHP version | register_globals status |
| <4.2 | default ON |
| ≥4.2 | default OFF |
| 5.3.0 | deprecated |
| 5.4.0 | removed |
For specific purposes, register_globals offered a useful and interesting option. However, its inherent security risk led to its removal from PHP.

Jack of Oracle Tutoring by Jack and Diane, Campbell River, BC.Returning from the gym this morning, my son mentioned Eddie Hall.
“He dead-lifted 500kg. From the exertion, he forgot his children’s names for two weeks.”
I paused, then looked at my son. “Well, I guess that was a great accomplishment, then.”
“Obviously.”
When a person is really devoted to a pursuit, they celebrate the sacrifice it can take.
