Mama told me not to come.

She said, that ain’t the way to have fun.

  • Generally the US should start having a not shoddy electricity grid, brown- and blackouts and you call yourself a developed country?

    I just want to say I’ve never had a brownout in my part of the US, and the only blackouts we’ve had are due to weather or a car hitting a pole or something. And our electricity is inexpensive.

    I’ve mostly heard of these issues in California and Texas, because of unique issues with their power utilities.

    And yeah, I think both the AI hype and disdain are stupid. It’s a tool that does less than proponents claim and more than detractors claim. Don’t blame all our problems on it, and don’t suggest it’ll solve all our problems.









  • I have tracks near my house that I could take to work, if they bothered to extend the line. There are some parts that need repair, but the land exists and the rails are largely unused for freight and mostly used to store extra cars. It goes right through most of the city centers in my area, and a large company has already promised to create a ton of jobs if the line is built. Oh, and there’s crazy congestion on the highway that runs parallel to these tracks, and these tracks go right next to two professional sports stadiums.

    So when are they starting construction? Not until 2050 at the earliest… Why? A handful of people in one small area of the line oppose it…








  • Information theory is all about cutting through the waste of a given computation to compare apples to apples.

    I’ll replicate an example I posted elsewhere:

    Let’s say I make a machine that sums two numbers between 0-127, and returns the output. Let’s say this machine also only understands spoken French. According to information theory, this machine receives 14 bits of information (two 7-bit numbers with equal probability for all values) and returns 8 bits of information. The fact that it understands spoken French is irrelevant to the computation and is ignored.

    That’s the same line of reasoning here, and the article makes this clear by indicating that brains take in billions of bits of sensory data. But they’re not looking at overall processing power, they’re looking at cognition, or active thought. Performing a given computational task is about 10 bits/s, which is completely separate from the billions of bits per second of background processing we do.


  • You’re misunderstanding the terminology used then.

    In information theory, “bit” doesn’t mean “bitrate” like you’d see in networks, but something closer to “compressed bitrate.”

    For example, let’s say I build a computer that only computes small sums, where the input is two positive numbers from 0-127. However, this computer only understands spoken French, and it will ignore anything that’s not a French number in that range. Information theory would say this machine receives 14 bits of information (two 7-bit numbers) and returns 8 bits. The extra processing of understanding French is waste and ignored for the purposes of calculating entropy.

    The article also mentions that our brains take in billions of bits of sensory data, but that’s ignored for the calculation because we only care about the thought process (the useful computation), not all of the overhead of the system.
