Cooking: internal temperature increase

Self-tutoring about cooking: the tutor mentions an observation.

Today I was heating some chicken burgers whose instructions suggested, for a start, to bake them in a preheated 425F oven for about 20 minutes, then continue until an internal temp of 165F.

The chicken burgers were frozen, so ideally they started at 0F. After 20 minutes I checked the internal temp: only 140F. I put them in for another 8 minutes at the same heat. Checking afterwards, the internal temp was 210F: it was 50% higher than at 20 minutes, from cooking only 40% longer.

Perhaps internal temperature can rise more quickly during the last minutes of cooking. There might be several reasons. As water evaporates from the food, for instance, it likely becomes easier to heat.

Programming: Java file runs w/o compiling

Self-tutoring about Java: the tutor mentions an interesting observation.

This morning, on this computer, I updated Java to openjdk-13. Having done so, I wrote a small class file to test the installation.

On the command line I forgot to compile, just typing
java Testfile.java
which ran. Apparently, it’s possible now:

Music: “Kiss You (when it’s dangerous)” part II: the video

Self-tutoring about music videos: the tutor mentions one he’s long considered.

In yesterday’s post I mention “Kiss You (when it’s dangerous)”, circa ’85, by the band from Ottawa, Eight Seconds. It’s a song I remember from then, but I’ve grown to like much more since.

“Kiss You (when it’s dangerous)” caught my attention when I first saw it on CBC’s Video Hits back in ’85 or ’86. As I mention yesterday, music videos were relatively new back then. Many (or most) tried to tell a story, with varying success.

In my opinion, “Kiss You (when it’s dangerous)”‘s video shows that the band Eight Seconds were ahead of their time in understanding the music video medium. In about four minutes, the video tells a coherent, haunting story:

The band members (as explorers), searching a forest in the dark, enter a clearing, at whose center is a white square platform raised above ground by a set of stairs. On top of the platform, on a stone slab, lies a priestess in white, apparently dead.

But for the body of the priestess, the area is deserted, possibly for some years: the explorers brush leaves and dirt from the staircase and platform, and discover musical instruments among the debris. They start playing. Soon, the body of the priestess disappears, in a flash of light. Yet we see her – with three others – looking on, perhaps from another dimension.

The rainy season comes while the band continues to play. Then comes the summer, and you can see the band members struggling with the heat as they play. A priestess appears among them sometimes, and can be embraced and kissed. She’s not the same one they discovered on the slab. Yet, like her, she can disappear in an instant.

Leaves blow around and lie thickly on the platform steps: fall has arrived. A different priestess is present.

The four priestesses appear in their other dimension, all in white. Their leader has snow in her hand, which she lets fall. The priestesses now desert the band, who continue playing, struggling in the snow and cold. Eventually the band succumb to the cold and we see them lying under the snow. The winter(?) priestess returns to survey the scene. In the snow, the instruments lie in ways similar to how they were found at the start of the video.

Apparently the clearing with the platform is cursed somehow: those who find it can’t leave, but are compelled to stay and play the instruments. Perhaps the priestesses help sustain them through spring, summer, and fall, but when winter arrives, the priestesses finally desert them so they yield to the cold. When new people arrive, they will find the instruments, so the cycle will recommence.

I think the video tells a clever, haunting story, reaching to viewers on a much different level than many videos.

Canadian culture: Eight Seconds: “Kiss You (when it’s dangerous)”

Self-tutoring about Canadian culture: the tutor mentions a song he continues to enjoy.

“Kiss You (when it’s dangerous)” came out around ’85, as I remember, having seen it on CBC’s Video Hits show. Samantha Taylor mentioned the band – Eight Seconds – were from Ottawa.

Music videos were an experimental medium back then, often competing with the song for attention. Therefore, I saw many videos, but sometimes forgot their songs.

“Kiss You (when it’s dangerous)” is a catchy song that continued to revisit me, in the 90s, from the radio. I’d be driving – often alone – when it would start with the keyboard, bass, and drums. The fullness of its beginning would seize me – “What’s that song?” I would wonder. Then I’d realize: “Kiss You (when it’s dangerous)” by Eight Seconds, from ’85. By then, it was 15 years – or more – since.

Reaching the YouTube era, I looked for “Kiss You (when it’s dangerous)” and found it easily. I was excited to revisit the video – and song – from over twenty years earlier.

I’ll follow up about the video.

Smartphones: a way to get rid of “Unfortunately, Google has stopped”

Self-tutoring about a smartphone: the tutor mentions a solution he found.

Recently my smartphone (Nexus 4 from 2013, I believe) started popping up a message pane: “Unfortunately, Google has stopped.” It would pop up over and over, sometimes only a few seconds apart; texting, etc., got difficult to do.

At the same time, the phone appeared to work normally, save for the annoying pop-up that kept getting in the way. I’d hoped it would just stop, but after about 10 days I decided to take action.

I’m no tech expert. I followed a solution shown in this video from the YouTuber Ultimate DIY. The pop-up no longer happens. Whether it’s the best solution I don’t know, but it’s apparently worked for me.

Health: Shoulder injury, two months in

Self-tutoring about health: the tutor reports on his shoulder injury, which happened two months ago.

As I report in my post August 22, my shoulder got injured August 7. An X-ray suggested bursitis, tendinits, and calcification.

During the first week after the injury I could barely move my right arm from the shoulder, and the pain was intense in the evening. Mobility did begin to return during the second week, but some movements were still impossible. In the morning, after sleep, the shoulder would be tender. However, during week 2, the pain vanished.

Three weeks in, I could write on the board all day. Stiffness still prohibited certain movements – the mobility gains seemed to slow down. I recall starting the lawn mower with my left hand, which was awkward. I guess that was a few days before school resumed.

A week ago I woke up and knew something was different, but took until the following morning to realize what: the shoulder wasn’t delicate when I woke up. On second thought, it wasn’t complaining anytime, having regained equality with my daily activities.

The shoulder isn’t strong yet – I can’t return to martial arts, probably for months. I’m keeping in shape with running, the stairclimber, and other cardio activities. If I ever restart bench press, it’ll likely be at square 0.

For everyday life, though, the shoulder is a match, which was hard to imagine six weeks ago.

Tendinitis or tendonitis – which one is correct? Both are, it turns out: they mean the same.

English: preventive or preventative?

Tutoring English, questions arise I’ve wondered about for years.

Preventive or preventative? According to Merriam-Webster, they’re equivalent.

Weather and seasons: frost today?

Self-tutoring about weather and seasons: the tutor mentions a surprising event.

Normally, in our family, I’m the first up in the morning. Lying awake, around 6:20am, I heard no crickets. I speculated the overnight temp must have been low enough to quiet them.

Some minutes later, at the computer with a coffee, I checked the temp. Would you believe it was -2C?!

At first I didn’t believe it, so I went out to check. In the dawn twilight I could feel that, indeed, the temp might be sub-zero.

Maybe I shouldn’t be too surprised: Oct 4, 2018, dipped to -2C as well.

Math: break-even year-over-year

Self-tutoring about math: the tutor mentions perhaps an oft-considered question.

Suppose an investment loses x% this year. What percent does the resulting sum need to gain next year in order to break even?

Imagine an investment of initial value $250. If, for instance, the investment loses 12% this year, it’s worth 250(1-12/100)=220 at year end. The % growth needed, the following year, to return to $250 is (250/220 – 1)x100% = 13.64%.

In general, if an investment loses x% this year, its result will need to grow by (1/(1-x/100) – 1)x100% next year to break even. So, by the example above, an investment that loses 12% this year will need to gain
(1/(1-12/100) -1)x100% = 13.64% next year to break even.
