> It's a larger data-set not a more complex problem.

Ummmm... yeah, scaling the kinds of algorithms that one might apply to this sort of problem up to larger data sets is often extremely difficult.

stevenbedrick··on Introducing OneNote for Mac
Yeah, I just noticed the "can't drag pictures in" issue. If anybody from the OneNote team is reading these comments, this is a pretty big missing feature. Mac OS is all about drag-and-drop, and a well-behaved app (especially one that is supposed to be a notebook-type thing) should be pretty robust in its d&d support.
stevenbedrick··on Why Silicon Valley should settle in Oakland
Very good point.
stevenbedrick··on Why Silicon Valley should settle in Oakland
Housing in Portland (particularly rental housing) is getting less affordable by the day, and the city is very aggressive about land use planning. This is, of course, one reason why the city is so nice... but it also means that there is a very fixed amount of buildable space, literally all of which is already taken. Infill is certainly happening, but the city really can't absorb any larger of a population increase than it already has over the last couple of years.
stevenbedrick··on “Marriage promotion” is a destructive cargo cult
I imagine that it depends on the state (or country, if we're not being US-centric), but many non-married couples can and do set up durable powers of attorney (PoA), advance medical directives, wills, and so on.

As a sibling commenter noted, the trick is then getting the hospital, partner's family, etc. to recognize the PoA document; while the law surrounding powers of attorney is generally quite clear, there are certainly plenty of horror stories of hospitals, families, etc. ignoring such documents. I imagine that the likelihood of this happening varies from state to state, hospital to hospital, possibly even doctor to doctor, and so on.

That said, in the US, basically all of the time, you'll be _far_ better off for having drawn up a durable power of attorney than you would be if you hadn't. Definitely money well-spent if you're in an unmarried partnership. I suggest finding a lawyer who specializes in LGBTQ family law; they generally will be happy to take any couple on as clients, regardless of whether they are same/opposite sex, cis/trans, etc., and they have literally "seen it all," which means that they know about all kinds of legal edge cases that can cause trouble for people in a non-married partnership.

As an aside, I'm continually amazed by how many _married_ couples don't have wills, PoA documents, advance directives, etc. etc. filled out. Even if it's not strictly necessary from a legal perspective, having one's wishes and instructions written down explicitly is a relatively small-seeming thing that can make a very bad situation noticeably less awful (or so I've heard from people who've been there).

stevenbedrick··on Caltech Announces Open Access Policy
Google Scholar has a reasonable interface, but I find its actual content to be unreliable at best. Downloading references in e.g. BibTeX format, I almost always find significant errors, sometimes in relatively innocuous fields (different formats of a conference name, etc.) but other times in more important fields (authors' names).

It's a great tool, and I use it all the time, but it's certainly no replacement to a properly-managed bibliographic database.

stevenbedrick··on Caltech Announces Open Access Policy
> I can't wait for a day when we get a centralized, non-profit, publish/subscribe consumer service for all the papers that ever get published by major research universities (with a good search tool)

You probably know about this already, but if you're interested in anything biomedical in nature, the US National Library of Medicine's PubMed interface to the MEDLINE database (also managed by the NLM) is exactly what you describe: http://www.ncbi.nlm.nih.gov/pubmed

MEDLINE is a bibliographic database that indexes all of the abstracts going back to the 1960s from literally every major (and almost all minor) journals that do anything even remotely related to biomedicine, and also include a surprising number of physics and CS journals. It features a robust and easy-to-use API, and has since the 1990s. All MEDLINE entries include obvious bibliographic metadata (titles, authors, abstracts, dates, etc.) but also include human-curated index headings, which makes searching way easier. PubMed's interface makes it easy to construct complicated and accurate queries, and the NLM offers online access to their reference librarians, as well.

Furthermore, any published research that is funded by the US National Institutes of Health has to have its full text (including figures, references, etc.) posted to PubMed Central (PMC), which is another online database that the NLM maintains. This is an actual law- if you get money from the NIH, your publications have to end up in PMC following a short embargo period- I think it's about six months post-publication?

All of the PMC content is available free of charge, and it also has an API. It is not a complete full-text mirror of MEDLINE, because not everything in MEDLINE was NIH-funded, but for research going back over the last 7-10 years or so it is often surprisingly complete.

This is one area where biomedicine is way ahead of computer science. As somebody who's worked a lot in both fields, I definitely find myself missing PubMed whenever I need to look for CS literature...

As an aside, the National Library of Medicine is truly one of the hidden jewels of the US government. Its budget is tiny, but it somehow manages to produce fabulous work and performs a vital service for the research community. And almost nobody has heard of it!

Your point is a good one, but maybe a different procedure would be a better example- most people suffering from an intracranial hemorrhage aren't in a position to do a whole of of comparison shopping on where to have it taken care of.

Nope, you're not the only one. I've been wondering for years how 23andMe has been getting away with what is clearly a flagrant violation of FDA marketing rules.

stevenbedrick··on Ask HN: Where do you find interesting papers to read?
The ACL Anthology is a free online archive of the last couple of decades' worth of Association for Computational Linguistics-sponsored journals and conference proceedings, which is where many people working in computational linguistics, natural language processing, machine translation, etc. hang out and publish.

HOWTO get started:

1. Pick a recent conference;

2. Click on the titles of any articles that look interesting;

3. When you get to the end of each article, dig through its bibliography. Many/most of the paper's references will also be available in the ACL Anthology; if not, Google Scholar will probably be a good resource for chasing them down. GOTO step 2.

Enjoy!

stevenbedrick··on Intro to images in Go – concurrency
This is probably a stupid question, but is the Canvas's DrawLine function thread-safe? It looks like multiple Nodes could be drawing to the same canvas at the same time, and I don't see any locks/mutexes/whatevers wrapping that call.

Obviously it can't be too much of a big deal, since the (very nifty) example works just fine, but I'm curious about what's going on here.

stevenbedrick··on David Miranda, schedule 7 and the danger that all reporters now face
Thank you. This is an important point, and one that I haven't seen nearly enough of on HN lately. It is very difficult to overstate the extent to which "government people" live in a bubble. In many ways, they are working from an entirely different set of first principles than those used by most of the HN-reading world. As such, it is difficult for "us" to understand why "they" do what they do, and very easy for us to come up with our own (usually incorrect, or at the very least, incomplete) explanations for their behavior.

Of course, the converse is generally true: the laughably incorrect explanations that "government people" always seem to come up with for "our" behavior often are the result of them interpreting events, statements, etc. through their lens- a lens informed by a completely different set of optical principles than the ones that we are used to using (to abuse the figure of speech a little bit).

In other words, when you read or hear about a "government person" doing or saying something head-deskingly stupid, the odds are very good that the statement or action made perfect sense in the context of that government person's world. It's not that they're (necessarily) stupid, or even ignorant- just that they're not living in our world, and so have dramatically different motivations, constraints, first principles, etc. etc. Their actions may be perfectly follow an internal logic- but it's not our logic, and so we have a hard time making sense of it.

And all of this goes double or triple when we're talking about military or IC people. The classified nature of their work, with its attendant organizational, cultural, technical, political, and psychological distortions, makes their "bubble" look more like a bathysphere.

They also didn't seem too interested in our application for a radiation oncology treatment planning tool, so maybe they just weren't into medical stuff?
stevenbedrick··on How I Learned to Stop Worrying and Love the Tenure-track-faculty Life
She actually does mention teaching- she lists sub-par problem sets as a contributing factor to a particular month being difficult, and she groups teaching in with research as her non-quota-having activities. But I suspect that your analysis is fundamentally correct.
stevenbedrick··on Welcome to Google Island
Good point, and there are a lot of factors that go into it. r00fus made a similar point in a sibling reply, and I absolutely agree that users like us are quite different than 99.99999% of Google's other users- it definitely sounds like we have similar family members. And as I replied below, experts and novices have very different needs in terms of their information behavior.

I still don't think that lets Google off the hook, though; it just makes it more important that their personalization strategy be backed by very flexible, granular, and technically meaningful privacy controls. It means that Google should be setting an even higher bar in terms of educating their users about precisely what data gets collected and exactly how it gets used- and they should empower their users to control how that personal data impacts their experience using Google's products.

The number of their users who actually care about this stuff right now is basically a rounding error when compared to their total user numbers, but that doesn't mean it isn't important. And hopefully, as more and more of our life is conducted online, the number of people who care about this will increase.

stevenbedrick··on Welcome to Google Island
Yes, I've noticed that corporate PR statements that begin with "To serve you better..." rarely end particularly pleasantly for me as a customer.

It makes more sense, of course, if we interpret such statements through the lens of the Twilight Zone episode, "To Serve Man." :-D

stevenbedrick··on Welcome to Google Island
That's definitely a fair point- "experts" have very different search behavior from "novices", and could potentially get more benefit from personalized search support.
stevenbedrick··on Welcome to Google Island
> Keyword search isn't good enough anymore

Citation needed.

I'd actually be quite satisfied if the current state of the art for general-purpose web IR stayed about where it is now- it's pretty dang good! I can't remember the last time I needed to find something using text search and was unable to. And when Google folks talk about making search "better", what they seem to generally be talking about these days is making it more "personalized", which strikes me as a questionable goal in terms of costs and benefits. Cost: living in an electronic panopticon the likes of which Orwell could never have envisioned, having my private information used as a raw material for somebody else's monetization strategy, etc. etc. Benefit: marginally better IR?

Note that I'm not writing this as some sort of technophobic Luddite- I'm actually an academic researcher who works on IR problems. I guess it's just that I, as a potential end user, don't see enough value in hyper-personalized search to be worth the inevitable tradeoffs in terms of privacy and information centralization.

Plus, I'm absolutely not anti-Google, or full of conspiracy theories, or anything like that- but I still find it more than a little creepy to think about just how much information they have about me. Just sayin', is all.

stevenbedrick··on The N=1 Guide to Grad School: Advice for Aspiring PhDs
That said, while your advisor's job is in part to protect you from whatever politics are going on in your department, it is important that you not be completely politically naïve when you finish.

So your advisor probably shouldn't try to keep you totally in the dark if there are political shenanigans going on in your department or university... but they should do what it takes to ensure that those shenanigans are "not your problem." In other words, said shenanigans should be educational (possibly even entertaining), but not distracting, stressful, or have any other impact on your primary purpose in life: getting your dissertation out the door.

stevenbedrick··on The N=1 Guide to Grad School: Advice for Aspiring PhDs
A properly-run academic department insulates its students as completely as possible from politics. If, as a student, you're having to concern yourself with departmental politics, it's a sign that your advisor isn't doing their job.
stevenbedrick··on What is the rule for adjective order?
In case anybody's interested, one of our (former) graduate students has done some really fascinating work on computational analysis of prenominal modifiers (adjectives, etc.). For example, her ACL paper from 2011:

Mitchell, M., Dunlop, A., and Roark, B. (2011). Semi-Supervised Modeling for Prenominal Modifier Ordering. Proceedings of ACL 2011. http://www.aclweb.org/anthology/P/P11/P11-2041.pdf

stevenbedrick··on Apple fires Chinese supplier for using underage workers
> While it sucks for the workers at the plant that they're probably going to lose their jobs...

From TFA:

    When new violations are found, Apple requires its suppliers to return the workers back to a school chosen by the family and finance their education. "In addition, the children must continue to receive income matching what they received when they were employed. We also follow up regularly to ensure that the children remain in school and that the suppliers continue to uphold their financial commitment," wrote Apple in its latest report.
