Deepmind will start playing fair?

195 words

In case you missed it, last week bought the most exciting piece of AI news of the past couple years. Deepmind’s Alphastar will be playing real non-NDA’d humans for multiple games (via Ars Technica).

This is cool news. Partly because they finally seem intent on fixing their cheating with superhuman micro, but mostly because repeat games could allow humans to develop counter strategies. The exhibition matches earlier this year only had the humans play one match against any given bot, thus giving the bot a huge informational advantage.1The neural nets were trained through supervised learning on human matches before being pitted against each other. These new matches will hopefully end up being more fair. However, Blizzard’s press release is vague enough that Deepmind could still decide to play only a hand full of games, which would prevent humans from gaining enough knowledge to devise counter strategies. Worse, the Alphastar team could decide to stop playing once they observe online message boards sharing good tactics between human players or any other nasty hacking of p’s.

The hype labs haven’t been doing well in fair play or reproducibility so far, but I’m willing to hope they’ll improve.

Ovens have secret built-in automatic timers

269 words

Every oven I’ve ever used has had a secret function, a mechanism that automatically tells you when the food is ready. It is wonderful and I want to tell you about it.

So most ovens control their temperature using a bimetallic strip. When the temperature inside is less than the target temperature, the strip closes a circuit that activates the heating. As soon as the temperature is sufficiently big, the strip will have deformed enough to open the circuit and stop the heating. In many ovens, especially older ones, you can hear this as a soft *click*. If you are lucky, the mechanism is sensitive enough to rapidly go on and off to stay on temperature, at least for a couple seconds.

If you eat frozen pizza, it often only has to be heated to a sufficient temperature. When it reaches this temperature, the pizza will stop cooling down the air around it, thereby allowing the oven to reach its target temperature and starting to say *click*. So the sound will tell you when the food is ready, no need to read the packaging to find the correct baking time.

The same happens for dishes that are ready when enough water has evaporated, or when a certain endothermic chemical reaction has stopped happening. All are done the moment the oven says *click*. There might be some exceptions to this phenomenon, but I have yet to run in to one. Which is great because I always forget to read oven instructions on packaging or recipes before throwing them out. Try it out with your own electrically powered food heating units.

Which companies are adversaries?

I’ve been looking on and off for mp3 players for a couple months. I wanted a device with proper playlist support, bluetooth, and sufficient battery and storage capacity. It had to be cheap and with a UI that does not make me wish for death.

I ended up buying a $30 second hand Nokia Lumia 650. I deleted everything except the music player and maps app, downloaded maps of every country I might reasonably ever visit and the complete contents of Wikivoyage, copied my music onto it from my pc and put it permanently in airplane mode. It is a bit too laggy, but other than that I like this setup a lot.

But more important than my love for Windows Phone, is my hate for Android and iOS. I dislike the former for its role in the global surveillance economy and its butt-ugly interface. I dislike the latter because of its adversarial pricing model and excessively walled garden.

I don’t want to get my dinner from the pathologically neoliberal butcher, the dominant-strategy-playing externality-indifferent brewer or the stalking, price-discriminating, search-engine-optimizing baker. Their antithesis probably consist of the local organic farmer’s market, self-hosted FOSS software and artisan everything, but I do like economies of scale.

I’m still searching for the synthesis. For now, I’ll start with trying to minimize my interactions with companies who relate to their users or customers in a very adversarial manner
