For coders - Peter Norvig's PAIP (which might be The Best Programming Book, but no room to get into that here) talks about these and leads you through building something like EMYCIN, the base of a functioning expert system without anything particularly domain-specific.

But Norvig also put them in context, and left me with the impression that Expert Systems were proven inferior to Bayesian approaches for a lot of the problems they had been developed for.

I can well imagine, though, that there are problems where expert systems are a good fit.

As an interaction model and as a way of guiding control flow, as a weird and different way of handling user interaction and building extensible applications, I think the EMYCIN example from PAIP is pretty cool. I've wondered how possible it could be to use something like EMYCIN to write webapps ...

You might be surprised. The teachers that taught you relevant things that you end up using over and over tend to be remembered in my experience.

Of course some courses lend themselves to imparting this information better than others, and if you end up in fields other than your major there may be less chances to find your learning useful.

I think they are interpreting pivots as a sign that the founders and/or investors wanted to change direction, because the previous direction wasn't succeeding.

I'm all for small, sustainable sites which provide a service and don't try to monetise too desperately. But when you take $50 million in VC funding, surely the founders know they're boarding the ten-times-return-or-bust train?

> sounds which may not be perceptible in context

There is good reason to think that's different. Audio quality that's measured by subjects' ability to perceive, and report perception of a sound masks the difference between their ear being unable to detect a signal, and hence no signal comes over the auditory nerve and a situation where a soft sound might not be noticed in a loud passage but the ear responds to the signal.

Is this significant? One would probably have to do an FMRI study to answer that. In some applications, like understanding the words of someone speaking, by definition it isn't. But music is emotional and there might be aspects of music listening that are outside the ability to consciously report.

An obvious case of audition working when we can't consciously report what we hear is when we are sleeping, but experiments can detect the influence of those sounds.
But you also have to get rid of the packaging. I was imagining dumping a package of cocaine, but that's stupid: at least opening the packaging would help with the clogging by letting the cocaine dissolve. Not sure what the packaging would do with the pipes and whether this only packaging holds up as evidence.
I disagree. It gives you information you have to treat carefully, but it is useful.

Especially to compare different bitrates. I'm not even sure what bitrate this used, maybe 128 like the example files?

Just getting into development so its slow going. One of the ideas I am working on is a service which will provide a "one stop shop" to manage rental properties and rental relationships. It will includes things such as listing rentals, managing the viewing process, tenant verification, legal documents, and all financial transactions including the ongoing rent payments.

"Landlords" and "Tenants" would set up profiles which will be used to match prospective tenants with listings and vice versa.

Some of the key aspects of this concept are the creation of a marketplace to encourage rental unit upgrades, community management both for large apartment/condo complexes and geographical communities with large concentrations of rental units, and tie-ins with third party services / various partnerships.
It resembles programming koans — you fork a repository and run tests to see if you succeeded:

>At the start of every chapter, you should go to Github and fork the chapters repository. There will be a link to the appropriate repository at the beginning of every chapter. You then clone your own fork of the repository and start working with the exercises when you encounter them among the material. You create commits and maybe push them in to your own fork while working. You also run the tests with lein midje to see if they pass.

Note that they mean the "chapter's" repository, not a "chapters repository" that contains everything.

Grading is done separately: a continuous integration tool runs your assignment and replies with your grade.

>When you want your answers graded, you push all of your work with git push. You then go to Github and send a pull request. At this point, Travis kicks in. It runs the tests for your code and then comments on the pull request whether the tests passed or failed. A link is also provided to see the nitty-gritty details.

I think it's a great service, and was really toying with the idea of creating something like this when I was living in the UK. But mostly for ebay purchases.

There are lots of bargains for furniture and heavier stuff which is 'pick-up-only'. If you can get a quote for picking it up and delivering it before you even bid on an auction, this will open up loads more opportunities for both buyers, sellers, and local delivery companies.

So my 2 cents worth of tip is adding an ebay bookmarklet or a way to add an eBay id instantly to get a quote on.

Also lots of potential if this grows for moving companies who have extra space in their trucks to bid and fill those gaps within the area.

As a Serbian, I see a lot of rewriting history in recent years where Germans want to shift responsibility for horrible acts of savagery to others, especially as EU does carry some of the nazi ideals.

On the other hand, having more balanced approach to events is certainly welcome. Britain for example is not completely innocent at all and prevailing sentiment was always to blame Germans for everything.
That's pretty damn creepy too.
> (As did Scalia, Thomas, and Roberts)

Actually, if you read Scalia's dissent, you'll see it's much narrower than that. The only question before the Supreme Court was whether a preliminary injunction should be granted because Aereo was directly infringing the copyright holders' rights. He argues (and I agree) that Aereo couldn't have been directly infringing because playback of a recorded program was under the control of the user, and therefore Aereo does not commit a volitional act in playing it back. They could still be committing indirect infringement, and indeed Scalia explicitly admits that they probably are. That question is before the lower court, but the Supreme Court was not asked to review it.
I have enormous respect for Andreessen when he's talking on topics of his expertise, as in the first half of the article. And it's not just his talk, either; A16Z is a deeply impressive operation. But so far I find his take on Piketty shallow and unpersuasive; it strikes me more as the view that is convenient for him to have, rather than one of deep study and experience. I'd rather he stuck to what he knows.
95% of their peers dont get the funding these startup got.That's the problem.

If Quora was where it is without VC funding the article would have been quite different.

It would be considered a success.But when one is valued at close to 1 Billion yes it is an underachievement.

Remember 99% of VC fundings are about getting the startup bought at one point or an IPO with a big price tag so early investors can cash in,therefore => GROWTH is a major indicator of achievement. Venture capital is not free money.

> any company that can "use" "free" data from the air and resell it much cheaper than, say, the $150 cable bill, is going to be successful.

OTA broadcasts are free for everyone. You do not have to pay $150 a month to receive them. Aereo did not offer HBO or AMC or other cable-only channels through their service.

To me, the only real issue at play was whether it is legal for a person in OH to receive OTA broadcasts from NY. And there may be some merit there: some of the local stations might possibly be funded in part by local taxes.

# Low-Density Supersonic Decelerator (LDSD)

As NASA plans ambitious new robotic missions to Mars, laying the groundwork for even more complex human science expeditions to come, the spacecraft needed to land safely on the red planet's surface necessarily becomes increasingly massive, hauling larger payloads to accommodate extended stays on the Martian surface. Current technology for decelerating from the high speed of atmospheric entry to the final stages of landing on Mars dates back to NASA's Viking Program, which put two landers on Mars in 1976. The basic Viking parachute design has been used ever since -- and was successfully used again in 2012 to deliver the Curiosity rover to Mars.

NASA seeks to use atmospheric drag as a solution, saving rocket engines and fuel for final maneuvers and landing procedures. The heavier planetary landers of tomorrow, however, will require much larger drag devices than any now in use to slow them down -- and those next-generation drag devices will need to be deployed at higher supersonic speeds to safely land vehicle, crew and cargo. NASA's Low-Density Supersonic Decelerator (LDSD) Technology Demonstration Mission, led by NASA's Jet Propulsion Laboratory in Pasadena, Calif., will conduct full-scale, stratospheric tests of these breakthrough technologies high above Earth to prove their value for future missions to Mars.

> There are lots of us that live in areas with little if no content easily obtainable over-the-air, and our HOAs forbid larger antennas.

Your HOA cannot forbid a larger antenna for OTA broadcast reception. They can put some restrictions on where you place the antenna, such as requiring that it be in your back yard and not visible from the front, to the extent that those restrictions do not preclude reception or unreasonably raise the cost. (For satellite dishes, they can limit them to under 1 meter).

Here is a guide from the FCC explaining your antenna rights: http://www.fcc.gov/guides/over-air-reception-devices-rule
It's been many years since Andreessen's day-to-day concerns have been tech-related, rather than finance-related. Not too surprising he would have opinions common among people in the finance sector, considering that's what he lives and breathes (this doesn't mean they're right or wrong, just that they are unsurprising for someone coming from finance culture).

It probably doesn't help that he's in business and daily contact with Ben Horowitz, who is even more sucked into the norms of that culture (check out the comments on https://news.ycombinator.com/item?id=7191642).
1) Rails is more popular than Django. Rails was the first MVC web framework, and it has been embraced by the startup community for it's ease of prototyping applications. Because of this and the high-profile successes of major companies using Rails (such as Twitter) more people interested in learning to code are guided towards Rails as the first framework to learn.
2)I also suspect that the Rails community is more design-oriented than most other communities and so have pulled some designers, and front-end devs into the community
Notes on False Sharing
Given that there are only two kinds of evidence, circumstantial and eyewitness, and that eyewitness evidence is almost useless unless the witness knows the accused (and was close enough and had a good-enough look not to be mistaken) or the accused was apprehended in flagrante delicto, bet on circumstantial either way (to convict or to clear). Dismissing circumstantial evidence means that if you sort of resemble the impression that an eyewitness had of the perpetrator and were wearing clothes that were "brown, or maybe blue... it was kinda dark" and the testimony of that eyewitness just, you know, feels more credible than the seventeen people who will swear up and down that you were elsewhere at the time, then the more objective (but "merely circumstantial") evidence that can reliably place you elsewhere isn't going to be a whole lot of help to you.

That "legal overhead" is very real; without those lawyers fronting the money to pursue the case, we wouldn't be having this discussion in the first place.

It would definitely be cool to implement a `--hint` function to complement `--cheat`. However, in order to do so, I would need to find a resource that contained said hints on a per-problem basis.

Alternatively, if there is a generalized list of useful algorithms for Project Euler somewhere out there, it would be trivial to add it to a short "problem hints"-esque section in the readme.

Using Self Joins To Calculate Retention, Churn, And Reactivation Metrics
I follow Andreessen and a few of the other a16z folks on twitter, and every day they are tweetstorming what appear to be very insightful opinions and predictions on a whole slew of industries. And then I wonder if these guys are actually orders of magnitudes more intelligent than me and others, and have truly valid and well thought-out opinions, or if a good amount of what they say is nothing more than speculative bullshit that's hardly contested due to their reputation and success.

I've got enormous respect for them, too, but I'm beginning to think that the breadth and depth of expertise and foresight they display shouldn't be taken too seriously.
> And I should care about the trust backbone for my personal web-site and non-commercial projects why exactly?

You don't have to. Issue a self signed cert and provide instructions to add it to the browser as a trusted certificate authority. The fact that no one trusts you by default becomes your problem, the alternative is caring about the trust backbone (or I suppose, paying Microsoft, Apple, Google and Mozilla to add your CA, but I would guess that will run a bit more than $600/year.)

You have to wonder what the economic impact would be if government policy were driven by a top ten list of quality-of-life issues. Would there be PSAs on TV suggesting a bong hit instead of a drink? Would soda pop be locked up behind the counter? "Got more milk than you can digest?" How many points of GDP would it be worth to do the necessary social engineering?

You're correct about the forward secrecy. That's what I get for commenting at 2am. I was thinking about TLS where there can be a frequently rotating asymmetric key pair.

Why are you putting free in quotes? OTA television is completely free to consume.

Nobody is being undercut. Cable companies use most of that $150 to buy private content. Nobody is advocating for splicing into private wires and making copies.

We're in this weird situation where local TV companies tricked their distributor into paying them, even though they previously shouldered the costs of distribution themselves. I see that as the biggest injustice here.

>I simply can't wrap my brain around how content can be produced, grabbed for free, and - importantly - re-sold for profit.

Imagine a taxi that brings you to a free concert. There is nothing wrong with making a profit off of providing convenient access to something. That's what every ISP in the world does. They're not selling the TV shows. They're connecting you with the antenna that sends out free TV.
