Efficiency

I have 12 posts sitting in the drafts folder.
I have 2241 links flagged in NetNewsWire waiting to be posted.
I have an unknown number of links sitting on my desktops and browser tabs, waiting to be turned into posts.

Clearly, I need to be more efficient.

“Don’t Worry. Your Data is Safe.”

I took my laptop to the Apple Store to get it repaired. (The keyboard doesn’t work.) After explaining to the guy at the store, he starts taking down my contact info. When he’s done, he says. “And what’s your username and password? Don’t worry. Your data is safe.”

Aghast, I say “But my data is NOT safe if I give you my password!*

“Uhh….”

“Can’t you just boot off an external drive or something?”

“Well, umm… yeah, but this is how that prefer we do it.”

Sure enough, the Apple form has blanks for username and password.

In the end, I gave them Ming’s password, because really it didn’t matter. I was giving a perfect stranger an unencrypted drive. It does make me think though. After decades of telling users not to share they’re passwords. Not to give them to people saying they’re from IT. Not to trust anyone with your password, Apple is undoing this as part of standard operating procedure. Or maybe I’m just old, and I’m supposed to think of Apple as a parent.†

* Yes, I recognized the naivete of believing a simple password provided adequate security in this situation.

†My parents never read my stuff. I see no reason to read my child’s.

BestCast™

After years of development, Weather Underground replaces NWS forecasts with their own prediction algorithm that incorporates tens of thousands of personal weather stations – like my dad’s – into its forecasts. The algorithm is called BestCast™. The press release talks about 42,000 stations, but I suspect that actual number is a bit less. Wunderground came up with this figuring by summing the total number of stations from each of three different data sets, however a number of stations actually send data to many different sources. For example, thanks to wview, my dad’s station sends to directly to Weather Underground and to the National Weather Service’s MADIS program via CWOP.

Another thing that’s new on wunderground.com (or at least I never paid much attention to it before) is if you scroll down to the “Forecast” section for a location they publish the RMSE for this location both their forecast and the NWS forecast. As a data guy, I find that transparency absolutely wonderful. Also, they link to the predicted hour-by-hour weather for a location (I suspect this is using an NWS model, since it’s reporting for an airport.), and the NWS’s “Area forecast discussion”, which is a conversational and wonky forecast. Personally, I like how it discusses how different models agree or disagree.

Cryoscope

The Cryoscope by Robb Godshaw is a solid aluminum connected to a peltier, which is in controlled by a computer. The cube heated and cooled to indicate the temperature forecasted tomorrow. The cube doesn’t directly give the predicted temperature, since at room temperature, the metal cube is perceived as cold. Instead, a 73°F outside temperature is mapped to 85°F on the cube, since that temperature was perceived as neutral.
