Not helping.

Indeed, there are no clean hands. It is clear that Russia is the active aggressor. But the other side(s) didn't even start with a moral high ground to begin with given the young age of the country and entrenched history of corruption. Relatively small amounts of money are being poured on them from Europe (where does that actually wind up?), but not enough to do more than maintain it as a buffer zone against the bitter psychotic depressed bear to the East.

I hope I'm not being too cynical. I just don't see any obvious possible good futures from this distance. I hope people there can find another way!

Here's a great way to visualize traffic incident statistics. Has anyone applied this to data covering a much larger metro area?
Overview. To gain a better understanding of the safety concerns for bicyclists and pedestrians, Great Streets Mountain View has analyzed recent injury and fatality data. The charts and maps below are based on the bicyclist and pedestrian injuries and fatalities reported to the Mountain View ...

Are you familiar with You Are Here? They do interesting things with data and maps that covers a variety of topics. Bicycle crashes, for instance http://youarehere.cc/p/bicycle-accidents/chicago

"... the ability to attach ... used-defined, sandboxed bytecode to kernel probes. This allows user-defined instrumentation on a live kernel image that can never crash, hang, or interfere..."

It was tempting the make the ponycorn the thumbnail for this post, but heatmaps & histograms are so much more tasty and important.
I've taken one small step with eBPF, but it heralds one giant leap for Linux tracing. # ./bitehist Tracing block device I/O... Interval 5 secs.

Great bike to work day this morning. Took the 75 mile route through Los Altos, Page Mill, Pescadero, Stage and Tunitas with 19 other coworkers. Arrived drenched from a downpour for the last 40 minutes in plenty of time for lunch.

Not cool.
Do you like privacy? You’re going to hate this news. A federal court just ruled that law enforcement doesn’t need a warrant to obtain cell tower location data. This is just a year after the same federal court ruled that it did need a warrant, a move some called the biggest privacy wins in recent memory. Now it is a loss.

Sure. Lobbying legislators to change the law, and not traveling to the states that are part of the 11th Circuit, are strategies. But then I wasn't talking about a strategy to begin with, merely probable outcomes given the technical sophistication of judges in other circuits (a few in the 9th come to mind).

I should play some Pac-Man.
Pac-Man mobile games updated, plans for huge birthday bash in Chicago revealed, and what is Pac-Man Rebooted?

It always amazes me that it is even physically possible to build such elementary particle sensing systems. Subatomic particle interactions are always described as producing "flashes" of light when they happen to actually hit a molecule, yet doesn't that really mean one or two photons? And you want to build a sensor tank that can not only notice that on occasion but also notice two successive interactions at near the speed of light to determine direction and antineutrino likelihood? Wow.

Meanwhile I live not far from a linear accelerator where sensing like this must feel normal.

How not to do mobile web. At least it didn't ask me to install an app. Their desktop site is indeed mostly unusable on a tablet.

I wonder about apps which don't automatically register themselves as handlers for their site's URLs.

This answer to "What is the appeal of dynamically-typed languages?" is great. I think the argument also carries over to Go because Go's type system is so much simpler than that of other statically typed languages.
answer @nuttycom - Gist is a simple way to share snippets of text and code with others.

Finally! CFFI 1.0 is almost ready. CFFI gives Python developers a convenient way to call external C libraries. Here "Python" == "CPython or PyPy", but this post is mostly about the CPython side of CFFI, as the PyPy version is not ready yet. On CPython, you can download the version "1.0.0b1" ...

I rented a touring bike for the day. Great full fendered bike appropriate for the season and good advice on where to ride (including on the Forumla 1 race track :).
