Rate vs. timing (XIII) Flavors of spike-based theories (3) Polychronization « The Brian spiking neural network simulator

http://briansimulator.org/rate-vs-timing-xiii-flavors-of-spike-based-theories-3-polychronization/

It occurs in balanced excitatory-inhibitory networks with irregular activity and standard spike-timing-dependent plasticity, and in such conditions neurons are known to be highly sensitive to coincidences. In other words, it is a particular perspective on the dynamics of such networks.

In systems which meet some self-consistency criteria, the appropriate action can be modeled using a utility function which assigns points to each possible action. In such a system the rational thing to do is to choose the action with the highest utility value.

X11: How does “the” clipboard work?

https://www.uninformativ.de/blog/postings/2017-04-02/0/POSTING-en.html

Even worse than I thought. 1. Clients retain the data, so must keep a window around to 'own' the selection, but not the primary one because that may close. 2. You can specify a data type to get the data in, but there's no guarantee it'll be specifiable as MIME so good luck figuring out how to request the type you want. 3. Even though the client retains the data you can't request more than about 256k at once and everything larger must be retrieved in chunks via the X server. 3. There are two common clipboards and it is basically a matter of trying one and then the other. 4. There are also more clipboards (by convention) and in fact unlimited clipboards (the identifier is just an X atom). 5. Working around this with a clipboard manager is humourously inefficient because to re-host the clip data the manager needs to retrieve it with all its target types, and there is no way to discover which ones don't require the client to do extra work (e.g. GIMP providing 50 mime types for image data)

What Really Happened with Vista – Hacker Noon

https://hackernoon.com/what-really-happened-with-vista-4ca7ffb5a1a

1. MS neglected important hardware trends (mobile) because they were focused on software innovation; key features of successful devices in the 2000s (battery life, connectivity) were not really about software. 2. The focus on managed code as a response to security vulnerabilities was terribly overambitious and resulted in MS dropping the ambitious parts halfway through the development cycle.

Is the Hard Problem of Consciousness Connected to the Hard Problem in Physics?

http://nautil.us/issue/47/consciousness/is-matter-conscious

From my notes to M: not that convincing: Basically the argument is, as I understand it: 1. Science doesn’t tell us about “things in themselves”, but only about how they relate to other things. In other words we can accurately describe how a photon behaves, but we can’t say what exactly a photon fundamentally *is*. 2. It doesn’t make sense to have a universe of relationships between things but no actual things. 3. Consciousness is a way of describing things-in-themselves (the concept of “something being red” for example, which is something you understand as a thing even if you can’t really describe it) 4. So we posit that this set of things-in-themselves is the actual structure of the universe (the hardware) and everything we do is just describing interactions between those things (the software).

This claims to talk about consciousness, but actually ends up making the argument that to efficiently and dynamically make predictions one needs a) a rich variety of input categorisations and b) a locus of attention, neither of which require consciousness.
