A coronal mass ejection (CME) hit Earth's magnetic field on March 8th around 1100 UT. The impact was weaker than expected, sparking only a mild (Kp=5) geomagnetic storm. However, the storm could intensify in the hours ahead depending on electromagnetic conditions in the wake of the CME. High-latitude sky watchers should be alert for auroras

The Bitcoin Story
I wondered where things are now with Bitcoin and went looking for a report. This story at Wired is pretty good.
Raspberry Pi
$35 and $25 mini computers. The Verge.
Uh, that's “mini” in a new, modern sense, not in the PDP-11 sense. I used to say that, soon, we'd have computers that you could actually lose. “Did you notice were I put the email server? I can't find it!”

Radar images from the March 2012 tornado outbreak
from United States Tornados. “a collection of a handful of the most gripping radar images of the March 2, 2012 storms as they were occurring.”
Solar Flare
Watch for aurorae!
From Space Weather: “ Big sunspot AR1429 has unleashed another major flare. This one is the strongest yet, an X5-class eruption on March 7th at 00:28 UT. NASA's Solar Dynamics Observatory recorded the extreme UV flash”
And: “A coronal mass ejection (CME) hit Earth's magnetic field on March 7th at approximately 0400 UT. The impact was not a strong one, but it could stir up polar geomagnetic storms anyway. High-latitude sky watchers should be alert for auroras.”

Strings in Scheme Lisp
I was recently trying to find what string functions were built into Scheme. Yes, it actually is in the manual but my web search brought up this site: Python vs. Scheme: strings.
Spray-on Antennas
Using nano-particle capacitors. [Article at Discovery News]. I still don't know what to make of this—it feels somewhat like a hoax.
R-Like Statistics in Clojure
“Incanter is a Clojure-based, R-like platform for statistical computing and graphics.
Incanter can be used as a standalone, interactive data analysis environment or embedded within other analytics systems as a modular suite of libraries.” From incanter.org..

I'm not saying that getting in a United economy seat is _exactly_ like squeezing into a Mercury spacecraft. But there are similarities. (From @ihnatko)

From @mashable, in spite of the fact I despise these integer headlines.

Google’s Python Lessons are Awesome
via Hartley Brody
Google's Python class
The lovably geeky Nick Parlante — a Google employee and CS lecturer at Stanford — has written some awesomely succinct tutorials that not only tell you how you can use Python, but also how you should use Python. This makes them a fantastic resource, regardless of whether you’re just starting, or you’ve been working with Python for awhile.

Don't Return Null
Use a Tail Call. This is a fascinating read, particularly if you follow the links.
Drone Data
I found this interesting from the article Counting on a Rush to the Cloud from Bits.
It reminds me of astronomers returning from a run at an observatory.
(One interesting side note: The cameras on drone aircraft in Afghanistan take such precise pictures that not all the data can quickly travel over the local Internet connections to analysts in the United States. The usual method is to store everything in a local cargo container full of receiving gear, computers and storage, then airlift it home when it’s full, swapping out another container to absorb more info from the drones.)

Large Scale Design with Haskell
I'm revisiting the question, why and how is Haskell well-suited for large-scale projects? Here's one set of answers at Stack Overflow.
