- the Economist endorses the Liberal Democrats in UK election (in Europe, a liberal democrat is roughly the same thing as a libertarian in the US)
- “One of the most important lessons of Trump’s success is that classically liberal rhetoric and positions were not very important to voters.“
- “It turns out that Westerners are rational, virtuous, and liberty-loving, while Orientals are irrational, vicious, and slavish.“
- The West is indifferent to Afghanistan and Iraq’s world of terror
- Roman slavery, revolution, and magic mushrooms

When teaching the machine, the team had to take some care with the images. Thrun hoped that people could one day simply submit smartphone pictures of their worrisome lesions, and that meant that the system had to be undaunted by a wide range of angles and lighting conditions. But, he recalled, “In some pictures, the melanomas had been marked with yellow disks. We had to crop them out—otherwise, we might teach the computer to pick out a yellow disk as a sign of cancer.”
It was an old conundrum: a century ago, the German public became entranced by Clever Hans, a horse that could supposedly add and subtract, and would relay the answer by tapping its hoof. As it turns out, Clever Hans was actually sensing its handler’s bearing. As the horse’s hoof-taps approached the correct answer, the handler’s expression and posture relaxed. The animal’s neural network had not learned arithmetic; it had learned to detect changes in human body language. “That’s the bizarre thing about neural networks,” Thrun said. “You cannot tell what they are picking up. They are like black boxes whose inner workings are mysterious.”
The “black box” problem is endemic in deep learning. The system isn’t guided by an explicit store of medical knowledge and a list of diagnostic rules; it has effectively taught itself to differentiate moles from melanomas by making vast numbers of internal adjustments—something analogous to strengthening and weakening synaptic connections in the brain. Exactly how did it determine that a lesion was a melanoma? We can’t know, and it can’t tell us.
And, in the same vein, here are some thoughts on terrorism.
I’ve been busy with real life for so long that I haven’t been able to produce shorter blog posts that give you a snapshot into my daily thinking routine. That should change now, but for today I wanted to give a shout-out to a bunch of bloggers who have put NOL on their blog rolls. Please be sure to check them out and add them to your daily feeds!
- Catallaxy Files: “Australia’s leading libertarian and centre-right group blog”
- Farmer Hayek: A group blog of agricultural economists based out of the American midwest
- Maggie’s Farm: A group blog of non-conformists based out of the American northeast
- The Money Illusion: The infamous-though-prestigious economist Scott Sumner’s personal blog
- Policy of Truth: Irfan, David, and the gang discuss philosophy, Israel/Palestine, and American politics and culture (amongst other interesting things)
- Popehat: a law blog that is much more than that
- Samizdata: A (mostly) British group blog of libertarian-ish bad asses
These guys are all on our blog roll, too, so don’t feel like you have to save this page in order to find them in the future.
These guys are also really cool, obviously, so feel free to jump into their ‘comments’ threads and introduce yourselves. They’ll talk back.
I’ve noticed a trend over the past few years of blogs getting rid of their blog rolls altogether, and I think it’s stupid. People think it makes their blog look sleeker, and that blogging as a form of communication between like-minded people has come to an end, but that’s all hogwash.
Show these guys some love!
