Nokia 5110 - Back from the dead. Part 1: Nostalgia

I loved my Nokia 5110 and I wonder if it was possible to breathe new life into this long-shelved and still-memed mobile phone. As it turns out, not only is it possible, but it's going to be a lot easier than I anticipated.

Who doesn't love a classic Binary Clock? I remember getting one of these when I was in my 20's from ThinkGeek, and it was pride of place on my desk. LED's are a thing of beauty.

Algorithms are breaking how we think

Today, Alec Watson posted a video titled “Algorithms are breaking how we think” on his YouTube channel, Technology Connections. The whole thing is excellent and very well argued. The main thrust is: people seem increasingly less mindful about the stuff they engage with. Watson argues that this is bad, and I agree. A little while ago I watched a video by Hank Green called “$4.5M to Spray Alcoholic Rats with Bobcat Urine”. Green has been banging this drum for a while. He hits some of the same notes as Watson, but from a different angle. This last month has been a lot, and I’ve withdrawn from news and social media quite a bit because of it. Part of this is because I’ve been very busy with work, but it’s also because I’ve felt overwhelmed. There are now a lot of bad-faith actors in positions of power. Part of their game plan is to spray a mass of obviously false, intellectually shallow, enraging nonsense into the world as quickly as possible. At a certain point the bullshit seeps in if you’re soaking in it. The ability to control over what you see next is powerful. I think it would be great if more people started being a bit more choosy about who they give that control to.
