downer··on Personalized Education -- how would you do it?
> Telling me I need to take 10 minutes of tests for a site to be able to provide value isn't going to be an easy sell.

People LOVE those kinds of tests. Just look at all the ones on LiveJournal and OK Cupid. "Tell me about ME!!!"

[wipes tear] That's a good one!
downer··on Seth Godin on Iminlikewithyou: Learning from flirting
I'd consider it rather a problem to have a dating site that supported only Windows and Linux users.

At least Mac users tend to be attractive...

The people on the other side of that gap aren't legal anyway.
downer··on The Daily WTF - "Could You Explain Programming Please"
This is awesome. Sounds like Cargo Cult development almost.
downer··on Personalized Education -- how would you do it?
Naively I'd say you can't do it without a mind-reader. Someone may not know what they don't know; thus an intelligent agent probes to determine. This is where tutoring/mentoring comes in, but it's never exact, as the instruction from any given person is probably hardly ever the most effective way to get the concept across to someone else's brain.

Just present all the material and they can skip ahead as warranted. But books tend to be better at reinforcement than introduction; e.g. go out in the field with a paleontology dig and you'll probably remember stuff you learn much better because of the associations with all your senses at once.

I often note important but subtle points in material when re-reading on a subject after personal experience, which I missed when reading the same thing previously. In the repeat case I now have references, and the written word causes those experiences to spring forth from whichever compartment of my mind contained them, whereupon I can hold up the new piece of information to see how it fits, compare it to what's already there, add it in, and then pack the whole thing back up.

The best way to teach someone is to get them as engaged as possible through as many avenues into their brain as possible. You can read about elephants all you want but there's no substitute for meeting one in person.

> So, what you mean by saying something is more intelligent than something else?

Obviously people say that all the time despite our lack of a definition for exactly what it is, so we apparently don't need an exact definition.

> and unless they are deterministic, you can't write code.

You might be interested to know that the behavior of your OS isn't deterministic once you add a second CPU.

That sounds like something to score brownie points.

In reality, with their millions, there's nothing stopping them from re-Lisping it. (Not even time considerations -- when they were in negotiations to be acquired, they didn't do any development for months [1]. If you can get away with spending that much time not developing before you have money, you can get away with doing a rewrite after money is no longer a concern.)

downer··on Hero Worship in IT - Good or Bad?
> If anything, the celebrity around PG signals a deep desire for good, honest mentors.

I agree with the second part of this point; in regard to the particular subject, hopefulness that said subject will finance one's startup is an integral part of it.

Be sure that you have

 ProxyRequests Off
specified, with <Proxy [asterisk]> deny from all (or allowing just as needed). E.g. in Ubuntu, make SURE you link to proxy.conf from mods-enabled, because Apache has a horrendous bug where if it doesn't see that option in a config file it defaults to ON.

Which means people can joy-ride using your server as an open proxy.

I don't know what possessed them to make that an opt-OUT.

<Proxy *> -- news. yc markup bug, can't specify a single asterisk if italic markup follows.

> we are actually trying to define intelligence through IQ tests, for example

Fail. IQ tests only measure how well you do on IQ tests.

> The problem here is that not every human being is intelligent

Unless they're in a vegetative state, they are more intelligent than any artificial system, so far.

> Is that the way you formulate tasks for software engineers?

The only way to make a specification so precise that it does exactly what you want is to implement it, and then the code itself becomes the specification.

downer··on Hackers and Painters (on Google Books)
The only thing that has prevented nuclear genocide is mutually-assured destruction. If the U.S. could've gotten away with it, who knows how many cultures we'd have nuked in pursuit of the American Dream.

If anything, the spies who stole U.S. secrets inadvertently did the world a favor. Countries with a nuclear arsenal don't get invaded.

If Iraq had had nukes, we might have made major strides to become energy independent by now, instead of thinking it was easier to go in there, beat them up, and steal their oil.

PG on why Reddit switched:

"Incidentally, the last straw, I've been told, was some bug in CMUCL threads that kept making the system crash."

If we all took that attitude, we'd never get anything done.

The process of discovery is hands-on, learning by doing. You don't know all the rules at the outset, or all the definitions, or even know what you don't know. You find out as you go along. Thus it has been for every great invention from sex to agriculture to post-it notes to landing a man on the Moon and back to on-demand porn.

The real requirement is that we have some way to test it; that we can do, e.g. by conversation. To cop an example from quantum mechanics (which I know nothing about), we don't have to understand why it is like that in order to make predictions with it.

We don't need a clear and unambiguous definition of intelligence in order to tell that other human beings are intelligent. Likewise, we don't need one in order to start trying to create an artifice that impresses us into thinking it also is intelligent.

This was quite impressive, and on the right track, seemingly: http://hci.stanford.edu/~winograd/shrdlu/

downer··on How to become a programmer
> Where would you begin?

Begin at the beginning and go on till you come to the end: then stop.

> I do not want to wait five billion years.

You're darn well gonna wait -- and LIKE it!

Fortunately, it takes significantly less time than that -- no more than three and a half billion years. Haha, and you were worried!

I recommend throwing out the entire field of computers and starting from first principles. Let's put the Ermine back in determine and stop weaseling our way out of deterministic systems.
downer··on The Depth of eBay's Problems 1: Disappointed Buyers
[Meg Whitman, eBay's chief executive] wasted $2.5 billion on Skype under the "I better do something to justify my existence plan." She could have bought the Kinko's chain for the EXACT same price. To the penny. What a coup that would have been. What a great combination of services and opportunities. Oops, FedEx bought it instead.

Wow. Word to MY mother.

downer··on Schneier: Never use it (MS has added RNG that could have an NSA backdoor into Vista).
Vista is proprietary. They can stick in a backdoor wherever they want. Wasn't there recently an issue with Windows Update ignoring your settings and updating itself anyway?

Not to mention all the hidden metadata and undo information in your MS Word files. If you value privacy, using a proprietary OS (including OS X) is not the way to get it.

downer··on US, EU Reach Internet Gambling Agreement
How does making a deal with a country compensate the business owners for lost revenue? It's just bizarre that they would rather bribe other countries than allow money to come into their own country via legally-operated sites.

"Instead of rewriting its gambling laws, the U.S. rewrote its trade rules to remove the issue from the WTO's jurisdiction," writes Lorraine Woellert. "The prospect that other countries may take a similar tack if cases do not go their way has alarmed the international trade community."

Hey! No erasies!

Rewriting the rules after you already agreed to them... priceless.

I can't think of any phenomenon less likely area to have a simple algorithm than intelligence.

Cf. Evolution.

Amazing how people with all this knowledge still haven't gotten anywhere close to AI.

It might even be something simple, overlooked, done a little differently.
