So today I found myself looking up Wikipedia for standard temperature and pressure which as I understood it was 25°C and then right there in the standard laboratory conditions section it says “schools in New South Wales, Australia use 25 °C at 100 kPa for standard laboratory conditions”. I had no idea those “standard” conditions I learned in school were so specific to my context!

Wealth and money
I read this one: The Art and Science of Spending Money which was interesting, but I didn’t find myself agreeing with it much.
For myself I am quite sure that I don’t spend money in order to impress others. My discretionary spending is mostly directed toward my health, capacity, and growth.
On the health front I have a nootropics program which costs me about $4,500 per annum.
Under “capacity” are all my computers and electronics equipment, which give me a certain capacity to do particular kinds of work (the kinds of work I happen to be interested in).
And then growth is about information and learning, mostly books, but not only.
In my head things kinda work the reverse, and I worry “people are going to think I’m doing this to show off, but I’m really not, I just wanted to get an opinion…”.
Of course I am proud of things I have made such as my lab, and I enjoy showing them off, but I do so not to show you that *I’m* cool, but to show you *how cool my lab is*. If *you* have a cool lab, I would love to see it and bask in how cool it is with you.
Within my peer groups I’m somewhere in the middle between living in relative poverty and having extreme wealth, only the latter bringing me embarrassment.
Radio Shack (Tandy) Kit
So it turns out that in competition to the Maxitronix stuff that I was interested in there were a bunch of competing kits from Radio Shack / Tandy.

Empty $_FILES array with PHP file upload
Wow. I just spent a few hours debugging a problem with my PHP file upload. Turns out the fix was to include an ‘id’ attribute on the file input element. Have no idea why that is required or works, but it does.
