Captchas are just Turing Tests

The comments on Jeff’s post that Software development is basically a religion found themselves talking about Jeff’s captcha, which is the word orange. Always has been. Basically, there’s a mandatory field. Fill it in wrong, and you get no comment. But because having this mandatary, when’t a spam bot going to figure that out? You may as well have the word “orange” as text, not a graphic, and then the vision impaired can play too.

I think I’ve talked about this before.

BTW: welcome to the 6th of the 6th of the 6th. Finally Americans and the rest of the world can agree on the date.

Tell me how to fix the problem!

It timed out, or I closed something, or something. Then I tried typing, and Writely figured out I couldn’t prove I was me anymore:
Not logged in - fine. What do I do about that?
Not logged in – fine. But you’re meant to tell me how to fix the problem, or better yet, fix it for me.

Eventually I brought up the login screen in another tab, logged in, and all became good again.

Idiot builds Homemade Air Conditioner

Geoff has built a Homemade Air Conditioner – by running ice water (made from ice-cubes, and bottles of water he’s frozen in his freezer) through copper tubing at the back of a stand fan – fluid motion provided via capillary action.

Once the water runs out, the house has cooled off enough that the fan alone provides sufficient cooling.

That would be evaporative cooling, Geoff.

Geoff also suggests adding salt to your mix, because

this will drop the freezing point of the water and increase the cooling effect of the fan.

Uh, no. That would be lowering the freezing point of the water. It doesn’t lower the temperature of the water, it means that it takes more energy to freeze the water in the first place. But you’re already dumping frozen water into your water bucket, so you’re too late.

Geoff apparently had to “poke a little hole” through his flywire for the exhaust of his water tube, but draws the line at digging up his landlord’s garden to make a geothermal cooling system. I’m glad for his landlord, but what’s the problem with digging up a backyard only to cover it up again? A hole in your flywire is there for good!

Geoff goes on to suggest that if you hang a car radiator off your fan – in a bid to increase the efficiency of the system – you might want to check it can handle the weight.

Nice work Geoff.

Windows Automatic Updates

The following question is clear, with the answers easily and quickly selectable.
Ask me once, fine. Ask me every fricken ten mintues, I kill you! I kill you!
But if you pick “Restart Later”, it obviously means “Ask me in another ten minutes”. Which is tiresome over an eight hour day.

I now understand how toddlers get all that candy they eat.

DIY Digital Picture Frame

Full, step-by-step instructions (with pcitures) on building your own cheap and easy Digital Picture Frame. Answering an unasked question on the selection of componentry, the author says:

Why a toggle switch? Because toggle switches rule, that’s why. We don’t want no puny sliding power switches. Oh no, this power switch is 25 percent functional, 75 percent hardcore awesome.

But why do this? You can buy one for a few hundred bucks. I guess it’s just the whole DIY thing, isn’t it? I guess you’re also recycling unloved tech into totally hardcore awesome tech.
