  • In any fight, circumstances are king. You need far, far more variables defined in order to be able to answer this question, and even then it won’t be a certain outcome. Who has the element of surprise? What’s the age, weight, and sex of the tiger (and the wolves)? How recently have the tiger/wolves eaten? Does anyone slip on a banana peel during the encounter?

    Maybe we’re going about this wrong. Are you trying to make sure the tiger is dead or are you trying to use as few wolves as possible?

    Sorry, no, water is not a mineral because it doesn’t have a characteristic crystalline structure, and if a dictionary says otherwise it’s wrong: https://geology.com/articles/water-mineral/

    However ice can be, if it forms naturally - the definition of mineral is:

    A naturally occurring, homogeneous inorganic solid substance having a definite chemical composition and characteristic crystalline structure, color, and hardness.

    And yes, this means that if you grow a crystal like a diamond for example in a lab, technically it’s not a mineral (it’s just sparkling rock).



  • This wasn’t “his brain matter”, these were “neuronal organoids” (clumps of neurons) grown from harvesting white blood cells and turning those into stem cells. Then the clumps were networked together with a literal wire to conduct signals between them, for timing.

    Usually in organoids networks the wire delivers either regular, repeating inputs (“clean” pulses) as a reward for succeeding a task, or a random signal (“noise”) for failure; this is how they’re “trained” to play Pong for example:

    In more advanced closed-loop setups, organoid cultures are embedded within simulated environments that allow them to “interact” in a game-like world. By using high-density multielectrode arrays (MEAs) to deliver patterns of electrical signals, researchers can create closed-loop feedback systems that enable organoids to process and respond to certain inputs (Kagan et al. [2022]). For instance, in one experiment, monolayer neuronal cultures were given sparse sensory feedback about the consequences of their actions within a simulated game. The organoids displayed short-term memory by organizing themselves in goal-directed ways, effectively learning to complete simple behavioural tasks. This capability, made possible by reinforcement learning, allows organoids to adapt based on feedback, akin to how a human brain might learn from trial and error.

    These same methods are being used to train organoids as Machine Learning compute substrates, because they’re much more efficient than silicon: https://aapsopen.springeropen.com/articles/10.1186/s41120-025-00109-3








  • Zen is a fork of Firefox, supports Firefox extensions, and retains the built-in access to the Mozilla extension/theme stores from vanilla Firefox. If you go to install an addon, it even gives a popup to “Add to Firefox”.

    It’s a good browser with only minor issues. I’m on Win10; automatic updates don’t always succeed, and it seems like it blocks some communication between the 1password desktop app and the browser extension because I have to sign into each separately. Otherwise, I prefer it to Firefox in pretty much every way.
