As another commenter pointed out, the accuracy really needs to be evaluated using a validation set, not the test set--the approach described in the post is training with the testing data. In the field, we call this "cheating".

The basic idea of automatically tuning hyperparameters (the things this post discusses tuning with genetic algorithms) is cool, though, and is becoming a popular subject in machine learning research. A couple recent research papers on the topic are pretty readable:

Yes, even for DYI's, 3D printing now (even with the rough ones) is a cheap tool to just try out prototypes. And try out A LOT of prototypes cheaply. Even though they are slow, it is cheap and you just can try out so many things before you go to production with CNC & injection molding. And you can give away limited prototypes so you can do market research with the printed models; even though they are rough, I have seen them work well enough for people to get this 'wow I want this' feeling.
Even if it does require billions of flashes to begin to fade artwork in a gallery setting, consider some of the most popular pieces of artwork, such as the Mona Lisa, which are heavily photographed and will continue to be so over hundreds of years. Over time, it's feasible that enough people would photograph it with a flash that it would begin to fade.

If the data and its analysis in this article are correct, it doesn't make much sense to ban flash photography in most settings, but it does for things which are and will continue to be extremely popular for centuries.

Additionally, I think it is incredibly telling that we've been banning texting-while-driving and yet expect stationery, ~1ft away UI to be the solution. With texting, you still don't have the benefit of tactile feedback but you at least have the ability to try to steady the phone on your steering wheel to give you the best road:phone visual you could possibly get, it's closer to your face and you probably understand the UI better. All the same, it's been the cause of innumerable accidents. Given that you're likely using a GPS unit because you don't understand the area as is, these controls need to be on the steering wheel or accessed through voice controls. Even someone who understands their GPS still has to deal with the bumps and swerves of the road.

A small point, but your API doesn't appear to use any kind of authentication/authorization:

$handle = fopen("$sendy_url/subscribe/$sendy_email/$sendy_list/".str_replace(' ', '%20', $sendy_name).'/true', "r");`).

In theory, anyone who knows you are using Sendy (I'll assume looking at the headers in the emails sent would reveal that) could subscribe/unsubscribe any email address and possibly wreak havoc. You should secure that somehow: either an authorization scheme or a secret or SOMETHING.

Am I the only one who's not impressed at all by the touchscreen-based interior of the Model S? I can find the button I want to hit/knob I want to twist to adjust the radio or AC by feel in my current car, so I don't have to look at it while driving.

Buttons are good! I'd like buttons with little screens on them so that they can always display their function in the current "mode," instead of having to be labeled with multiple things in cases like that, but I'm not seeing the benefit of going full touchscreen. On a phone or tablet it's extra screen space for displaying content—but I don't expect to be browsing the internet or looking at a photo slideshow on the center console of a car.

The other is a link to a build of pnacl sdk that also doesn't include source (src/ folder is empty).

Am I being dense here? Where's the hg, github, code.google link that actually has the source code? I couldn't find where the source is. You would think that would be pretty obvious for an open-source project, like maybe some giant button on the project page.

Anyway it doesn't change the point. This isn't being developed as a public open-source project. It isn't designed to be easily added to browsers other than Chrome. Like ActiveX, it's being used as leverage to make one browser better at the expense of others.

(b) The US being two orders of magnitude more populated. It really is more of a continent than a country.

I don't think patents OR copyrights are moral. You shouldn't have the ability to stop people from using ideas in their mind (which belongs to them) even if you were the one who came up with the idea originally and put it into their mind. Other people's brains don't belong to you, neither does their equipment for making books, games, movies, music, medicine or anything else. If they can make it, why the hell should you be able to stop them from using their hands and their property to turn out exact duplicates of your own creations?

By the way Notch, I disagree with you on the government research thing. Government is terrible at just about everything. Instead, vital research should be done by the free market, but without the protection of patents or copyrights, as anyone who owns either is automatically a troll.

In a decade or three we'll be able to ask a computer to invent medicines and technology on the spot, so why should we let one person dominate something that is going to be so easy to discover and produce in such a short amount of time?
sure, having four devs organize this event would have been nice for credibility, but they wouldn't have necessarily throw a better hackathon just by being devs.

there's a learning curve to throwing good hackathons, just like with anything else. we talked to a ton of people before this event, including devs and other hackathon organizers, read every best practice we could find, and solicited a lot feedback from our attendees. sure, we made some mistakes (demos need to be queued up a la TC, peoples choice award needs to be fail-safe), but we'll fix them moving forward.

While it's not common practice, I strongly believe that for particularly important services, there should be a time delay built into the reset process, so that if a user's email account is compromised in such a way that both the attacker and the victim receive the emails, the victim gets a chance to stop the reset process before any damage is done.
Timing attack vulnerability. A negative containment check is probably faster (at least statistically measurably so) than a positive one, so you'll see three peaks:

It is just you: empirical evidence finds that balancing things out artificially increases participation without affecting performance. See, for example, http://www.tirol.gv.at/fileadmin/www.tirol.gv.at/themen/gese...

This isn't a quality problem: it is a cultural problem. There are enough high-quality women programmers out there to have 50/50 gender balance (obviously). It does not usually happen because of self-perpetuating social dynamics.

I notice you are only in favor of interventions that don't require you to do anything. What if overcoming bias required you, and everyone like you, to take a step back and create space where women can participate? Would you be willing to forgo participation in a hackathon to an equally-qualified women so that the other women would find it a more welcoming space?

I would, because the comfort of more-than-one woman is more important to me than my own participation. If I don't have a hackathon to participate in I can always start one of my own; I don't need to see participation as a zero-sum competition with the women and men around me.

Interesting link. I agree that perhaps the value is sometimes overstated and I agree that we are moving towards domain-based reputation, but I've personally been bitten by other customers getting my shared IP on a blacklist.

While it's true that ISPs and spam filters will take the reputation of neighboring IPs into account, surely having a dedicated IP insulates you from the actions of others better than sharing the exact same address as them.

I agree with the bottom line, though: use an ESP that has a low tolerance for shenanigans.

When you develop a model, for instance, when implementing a classifier, you supposedly want to apply the developed model to other data, i.e., data you don't have available during development.

In many situations, it doesn't make sense to test your model only when it's put to make or influence decisions in the real world (although you have to test in the real world too). You'll want to test the predictions of your model on data you already have the actual results for. To test your model you'll split your data into data you know and will let the model know about (training dataset), and data you know but the model can't know about (test dataset). That way you can use the data the model doesn't know about to make controlled experiments and compare models (and, if your data is really representative of the real world, your mofrl comparison and the performance of your chosen model will hold).

The moral of the story is: if you don't split your data, you won't have any idea of how it performs in the real world, you'll only know how it performs with data it already knew about.

To take a very recent bitcoin-related example, the owners of bitcoinica were using LastPass to manage their passwords. LastPass leaks membership through the "forgot password" function, and probably months ago an attacker determined that info@bitcoinica.com was a LastPass account. Then, when the bitcoinica source code was leaked, attacker tried the api key within the code (set as password by naive investor) and bam: synced with LastPass account to get mtgox passwords and clear out bitcoinica's mtgox account of ~$350k USD.

From an evolutionary psychological standpoint I find this ridiculous:

Traditional standpoint is that men go to places where women are (e.g. bars) and hit on them. This requires a combination of various skills on the part of men, including resource acquisition (to be able to buy drinks for women), social skills, and the ability to be aggressive in a non-threatening way (e.g. to approach an attractive woman and chat her up).

There are of course many variations on this, but the skills that men ostensibly need to succeed in them are, generally speaking, some rough combination of the above -- which, perhaps unsurprisingly -- are some combination of the same skills that many women would want for a male partner (i.e. assertive, successful, socially capable, attractive).

The presence of these so-called "feminist" threads on HN often take the form of hackers, who presumably do not have all of the aforementioned skills, attempting to get women to come to them. I think it is reasonably obvious that the motivations include the fact that people who do not have all of the aforementioned capabilities and who are limited to incredible hacking skills, want to be able to succeed with women (e.g. obtain sex and/or relationship) on their own terms.

Personally, I believe this is both selfish and a violation of evolutionary norms. Certainly, there is a place for certain types of affirmative action, but in this case (and many like it) it is pretty clear that the action is not made so that the end product is better (i.e. better computer programs built in less time), but that nerds get babes.

While there may be some success with respect to the unstated motivation, I think the fundamental dishonesty with respect to the approach vector means that you will never attract the type of woman that you would ideally want to couple with (yes, I'm speaking primarily to a male audience here).

There may be "good enough" couplings insofar as there clearly is some appeal here from the standpoint of women, given the relatively high salary of nerds (I saw some unusual couplings
in silicon valley along these lines, particularly in the South Bay), but I don't think this is a very good strategy long term.

At the very least, I think the motivations need to be clear. Why do dudes in industries that are dominated by dudes want to have women around them in the work place so bad? Yes, we know why, and so do most women. There are other reasons of course, but we have to be honest about all of them when we are coming up with a supposed "solution."
