An interesting little tidbit: ants and the TCP protocol behave very similar. Natural engineering:
This feedback loop allows TCP to run congestion avoidance: If acks return at a slower rate than the data was sent out, that indicates that there is little bandwidth available, and the source throttles data transmission down accordingly. If acks return quickly, the source boosts its transmission speed. The process determines how much bandwidth is available and throttles data transmission accordingly.
It turns out that harvester ants (Pogonomyrmex barbatus) behave nearly the same way when searching for food. Gordon has found that the rate at which harvester ants – which forage for seeds as individuals – leave the nest to search for food corresponds to food availability.
A good read about the perils of being a woman on the internet. Sadly nothing with which I wasn’t vaguely familiar, though the specifics drive the point home. The overview is pretty simply expressed by this point:
Abusers tend to operate anonymously, or under pseudonyms. But the women they target often write on professional platforms, under their given names, and in the context of their real lives. Victims don’t have the luxury of separating themselves from the crime. When it comes to online threats, “one person is feeling the reality of the Internet very viscerally: the person who is being threatened,” says Jurgenson. “It’s a lot easier for the person who made the threat—and the person who is investigating the threat—to believe that what’s happening on the Internet isn’t real.”

Really good piece about the secret world of high volume internet backbone operators and how their small political squabbles redound on the average person’s ability to have the internet work in the way they want.
“Right now, YouTube doesn’t work too bad on Free,” Felten said earlier this month. “Three weeks ago it was horrendous. A 30-second video, like an Angry Birds solution video, would take 12 minutes before the first frame moved. Right now, you get some lags but it’s acceptable. I suspect whatever they’re doing, they’re constantly shifting it so it doesn’t look like it’s constantly horrible.”
As always when the topic of internet comes up in a US context, it’s worth noticing how much worse the problem is made by the near monopolies most television and high-speed internet providers enjoy in the areas they serve.
The premise of this piece — stop using the acronym “IRL”! — is thin, but its substance resonates with the way I use (and love) the internet.
8. When you spend your online time on what really matters to you, you experience your time online as an authentic reflection of your values.
9. When you embrace online conversations as real, you imbue them with the power to change how you and others think and feel.
As an IE hater, I’m a fan of the globe metaphor theory.

That’s apparently the time that internet congestion is the worst. And though I’d take this result with a grain of salt, it makes some sense to me.
Speaking of international figures doing unexpected things, Demitry Medvedev has a video blog.
