Nietzsche accusing Socrates of being a hipster (ha!):

---

"And science itself, our science -- what indeed is the meaning of all science, viewed as a symptom of life? What is the purpose, and, worse still, what is the origin of all science? What? Is scientific method perhaps no more than fear and flight from pessimism? A subtle defense against -- truth? Or, to put it in moral terms, is it something like cowardice and insincerity? To put it immorally, is it a form of cunning? O, Socrates, Socrates, was that perhaps your secret? O, mysterious ironist, was this perhaps your -- irony?"

If Linus has to patch Linux to get his home wifi working, then what hope have the rest of us got?

"Year of the Linux desktop."

(haha, only serious)
 
Lazyweb update..

I've got a couple of days of actual results now, so maybe people want to get some early feedback on my attempt to get a virtual wireless network that looks like a single AP to clients, while having multiple APs to get better coverage.

So the reason I'm doing this is that we have this kind of rambling house, with my office above the garage, and just having a single AP has never worked very well for it. I've tried several different setups with multiple AP's, but they just haven't worked all that wonderfully. I ended up having reasonable behavior with having identical APs, but I still find that clients connect to the wrong one, and other clients get confused by having the same SSID with multiple APs and just connect to the first one they see.

And I appreciate the comments from people, but when looking at prices and availability, it was really a no-brainer. The Ubiquiti single-band UAP runs at about $60 a pop, so you can buy a three-pack off Amazon for $180. The other "commercial grade" APs that do this seem to be in the $800 range. For a single AP.

So with that no-brainer, I now have a UniFi zero-handoff network  at home. And as people told me, you really don't need to run the Java controller thing except for setup. Which isn't that big of a deal.

It all seems to work fairly well, except for the fact that the UniFi APs are apparently quite picky at authentication time, and really don't like clients that optimistically connect using authentication packets at high data rates. Which the Linux 802.11 layer does by default. 

So I'm blaming the UniFi AP for being fairly fragile at connection time. Tssk, tssk.

I have a patch to make Linux just connect at slower rates, and that makes it work well. That patch is almost certainly a good idea in general, and some drivers (like the intel iwlwifi one) already did it on their own because apparently driver writers had found other picky APs.

So I hope/expect it will be merged by the networking people soonish, but it is a black mark against the UniFi AP.

That said, $60 vs $800? Yeah, I think I can live with it.

The patterns of passive consumption that are philosophically baked in to the iPad are not a hurdle for developers and educators to overcome, they are a carpet bomb dropped on the city center of our teaching and learning.

The iPad is the part of the psychedelic experience where you sit back on the couch and go "Whoa, man."

Recent images I've been posting are outputs of computer programs I've been writing for the Chaotic Dynamics course I'm taking.

Here's another. This plot is called the 'bifurcation diagram' for the logistic map x_{n+1}=Rx_n(1-x_n) with R in (0, 4).

Sounds right.

Part of being 'chaotic' (they have a definition for this, even though it seems a bit soft so far) is what they call having a 'sensitive dependence on initial conditions.' This, like you said, means that there are big changes in long term behavior that can stem from small changes in inputs. Definitely makes prediction difficult (e.g., weather).

The connection with differential equations is almost certainly there. The text I'm reading spends a good deal of its time on them. Though, so far we've worked primarily with these discrete systems which (they claim) exhibit many of the interesting properties and behaviors but at a lower level of mathematical sophistication (which I can appreciate).

I like this piece of artwork, and I am intrigued by the title, Permutation of Eight.

It would be a fun to write a program that produced similar output either by a completely random process, or potentially by a Markov process trained on her works (would the two produce significantly different output?).

I also wonder if there is an encoded message here. These works predate QR and similar codes (http://en.wikipedia.org/wiki/Mobile_tagging) by several decades.

"The mind is identical to the brain, but not the other way around."

Ha! Couldn't have said it better myself.

Does anyone know the origin of this quote?

Bifurcations in the attractor of the Lorenz system due to smoothly varying one of the parameters.

I have seen many still images of this particular chaotic attractor. They typically look calm on the page.

I am starting to feel that there is nothing calm about this attractor at all.

Excellent animation, +Harold Hausman! I'm starting to understand what They Might Be Giants meant with their lyric “the spiraling shape will make you go insane”.

What sort of epistemic claim is being made by someone who tells you, "You don't know what you're talking about."?

+Brian Knab - I'm glad to have your attention on this channel. I was certainly thinking of you when I posted this.

On Friday I was both very Bob and very drunk; and at that precise point in the conversation I got very distracted by the word 'know' and didn't know how to respond.

Five-hundred iterations of x_0=0.2, x_{n+1}=Rx_n(1-x_n), with 1<R<4.

This time plotted on axes: x_n, x_{n-2}

Nice. Now the relation with Feigenbaum diagram is clearly seen.

I want someone to write a book titled, "Making the Contemporary Modern Again: An Instrumental Approach to Being with Anxiety" so that I can read it and it can be my favorite book.
