Ask HN: how to get into a data analysis / machine learning career?
Hi all,

I'm currently a PhD student in materials science working on a polymer microfabrication-oriented project. Initially I was very interested in this project but my enthusiasm level plummeted rapidly. I've stuck it out a few years partly through wanting to finish what I started and partly, I'm ashamed to say, through inertia.

However, over the past year I've also been involved in a side project which has involved some pretty interesting data analysis (some complex image analysis and analysis of fluorescence time series), and it's like night and day. Science is fun and my work is exciting again.

And it's not just this side project: I'm learning R in my spare time, and reading through course material from Andrew Ng's Stanford machine learning course. I also did some analytical work as an undergrad which I really enjoyed, but I felt like I was commited to the microfab path. I'm really regretting that decision now.

I'd love to be able to push my current research more in an analytical direction but that's...unlikely, to say the least. And while leaving the program would be a really bitter pill to swallow, so would spending three more years on a project I don't like, and feeling even more committed to the work after I got a damn PhD in it.

My question is, does anyone have any suggestions for how I might do a course correction towards analytical work after a BS in Physics and years in a microfab PhD program? Should I be trying to take classes in statistics or CS? Are there "entry-level" jobs in this kind of thing I could qualify for?

Note: I realize this is not necessarily a HN kind of thing, but I see machine learning and data-oriented discussion here fairly often and it seemed like a good place to ask. Pointers towards more information or other communities are welcome.
There is no proper math. 99.999999999% is a very silly number. The probability of all of Amazon's datacenters being destroyed in nuclear war within the next year well exceeds 0.000000001%.
You have no idea of what I have an idea. Why do conversations here seem to degrade into "You don't know what you're talking about?" Or as camperbob puts it, "Clearly you've thought a lot about this?"

bit sharing and open source are two topics that are so religious around here. This community has a huge axe to grind against powerful organizations who have profited off intellectual property. Why?

What exactly is so wrong about profiting off intellectual property? Software, music, movies?
A lesson I once learned from a mentor: attention to detail in the little things often demonstrates attention to detail in the big things.

No one really cares if you misspell a word, use the wrong tense, or make some other grammatical error. But sometimes, that's all they've got to go on to assess your attention to detail. I've seen vendors proposing multi-million dollar purchases rejected because of carelessness in their writing. And the explanation was always the same, "If he's that careless with his writing, how careless will he be with my business?"

When the division manager who has made us $90 million misspells a word in an email, no one bats an eyelash; he must have been in a hurry. But when a cover letter has errors, it really makes people wonder.
It's different for software companies.

Yes, this is a point I wasn't thinking about.
But in iPhone OS 4 multitasking is coming and is similar to the android one.

But I think (my personal opinion, not backed by any data) that this was a decision based on technical matters. From the quoted passage it seems that Adobe was keeping the technology for itself to outpace competition. I don't think this applies to Apple using multitasking while developers can't.
That's what I thought - I don't think I've ever seen an application that would bother with that difference.

This has been pretty obviously coming for a while, since Amazon has been talking about their upcoming Android tablet and its Kindle support. Still, it's great to see that this is a) still coming and b) not going to be restricted arbitrarily to a single tablet.

This, combined with the Notion Ink Adam whatever tablet (due sometime this lifetime) will definitely push me to drop the "real" Kindle.

*Edit: I was thinking of the Dell Mini 5 (aka Streak) tablet with the Amazon partnership, actually. So not an official Amazon tablet, but effectively the same as far as content apps.

That baby name graph is showing how popular names are over time. The NYT Box Office graphic does the same - http://www.nytimes.com/interactive/2008/02/23/movies/2008022... .

This kind of graphic is bad for showing exact numbers, good for showing relative share during time and change over time.

But the graph in the parent article wasn't making that comparison, so yes, it was a stupid, pet peevey way to do a graph.
Ask HN: How important is location, really?
We always hear how important it is to be in the Valley, but of course that advice always comes from people actively building companies in the Valley. And we hear from a few out-spoken companies how unimportant it is to be in the Valley, but of course they're actively building a business elsewhere.

I think Naval Ravikant makes a good point (http://startupboy.com/2010/01/17/why-you-need-to-be-in-silicon-valley/). For winner-take-all situations like Facebook or Twitter, you need every advantage you can get, and it makes sense to move to the Valley. But what about the other 99% of startups? (And development shops, and freelancers, and un-funded side projects, and the rest...)

I know plenty of companies move to the Valley after a certain point. And, although much rarer, some companies leave the Valley after starting there (for example, Wufoo).

So what do you think? To those people who have experienced both locations (SF and something else), what differences have you found?

How important is location, really? And why?
Help me understand this. Did you not have bandwidth caps?

I understand how 'one or two abusers' could clog up a network at, say, a university where there might not be per-port or per-device limits on bandwidth.

But I pay my $40/mo. for 10 down 1 up, and I never get more than that. How does, say, seeding WoW updates 'clog it up for everyone else'?

This kind of post is probably against the guidelines. It does not engage any intellectual curiosity, and probably falls under:

>Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.

This isn't meat & potatoes, this is cotton candy. There is already lots of it on Reddit.

Basically this is the kind of Reddit-like submission that has turned y-combinator alumni off from HN.

You mind it mostly because the Lisp funcall/lambda syntax is complex. Contrast with Smalltalk, which lacks special forms, and does use lambdas to get short circuiting:

someBoolean ifTrue: [ 'it was true' ] ifFalse: [ 'it was false' ]

Brackets introduce lambdas. I don't find this syntax clunky, and while I've never wanted to map ifTrue:/ifFalse: before, it's nice to be able to write your own special-form-like operators this way.
Because intelligence is a quality, not a quantity. That makes it like beauty and flavor, not height or weight. You can't put a point scale on it. Chocolate cannot be 7 better than vanilla. A beautiful person is not the one with the biggest lips and the largest cheekbones.

We we can do is to put general parameters around it, such as "beautiful people tend to be taller." In the same way, scoring generally well (over 120 or 130) on an IQ test is like saying you're tall. It's actually meaningless as to how smart you are, but they share some of the same parameters, so they will correlate a bit more.

"I want to suggest abandoning the article for the constantly updated topic page (a la Wave). The problem with an article online is that it has a short half life and gathers few links and little ongoing attention and thus Googlejuice. It’s for this reason that Google’s Marissa Mayer has been advising publishers to move past the article to the topic."

I like the idea. A lot. I would want an updating history of immutable canonical versions of a story, to reduce the re-writing of history that the internet makes relatively easy.

But I wouldn't want Facebook to actually be the repository of objects.

> But Firefox wins, against stereotype, for memory usage and page load speed (more so with ad blockers installed).

I'll agree on memory, and that's one of the reasons I continue to use Firefox but memory is not speed. It's my impression that Chrome wins on JS execution and DOM manipulation/reflow, which is really what I are about as a developer and (generally) as a user. When you're on a low end machine, these make a big difference. When you're on a machine like most developers have, it really doesn't except in technology demos.

The Jaegermonkey and Layers work should help out, but I'm not sure that Firefox will ever catch Chrome. It's a difference in development philosophy. Webkit reverts ANY performance degradation while Mozilla reverts all performance regressions except for new features. I prefer Mozilla's philosophy since the places where this matters is generally a performance vs edge case correctness tradeoff.

Good luck, if you have any questions about the service (first watch the videos ^_^ ) let me know. You can also send me a direct message from the link on my contact page if you need any more information from me, though i'll only give you the logs data for your account, and you will need to prove your ownership of the account.
I never said nobody uses it. We have several thousand free accounts. But we make it much easier & more appealing to sign up for a paid account.

P2P is a deliberately greedy process - you are consistently opening a large number of connections (as opposed to a single high volume connection).

One of the big issues with P2P is not the downloads per-se but the discovery process - that can seriously hammer the network (imagine how you stress test a server!)

Also; it's entirely infeasible to offer a service as you describe - partly because networks just don't work like that (this answers the other commenter too).

ADSL is a shared line; what other people are doing can adversely impact you regardless of the networks theoretical capability.

None of the other events she describes have an obvious sexual undertone, even if we accept the paper did. She appears to be describing a friendly person who enjoys talking to his colleagues about things he's interested in when he gets in to work. Let's look at her complaints:

1. He asked her to comment on a scientific paper involving sexual behavior in animals.

2. He told her about a book he was reading on Casanova — specifically that he admired Casanova's adaptability to different situations and skill at gambling (Note: This is the emphasis she herself gives; I'm not downplaying any sexual component)

3. He said he would like to do a course on "sinful" behavior such as gambling, in which he might dress like the devil on some occasion

4. He asked her out to dinner, saying she could bring her husband and he would bring his girlfriend. He showed up without his girlfriend, but did bring another companion in her place. At the end of the night he gave her a hug and kissed her cheek "in the presence of [her] husband"

5. He likes to come into her office in the morning and chat, often about technical fields outside of his degree

6. He initially complimented her along the lines of "You look good in that outfit," she told him she didn't appreciate that sort of talk, and since then he has been more distant and kept his conversation with her strictly to scholarly matters

The picture she paints of him is very much that of a friendly guy who likes to talk to his peers about the things he's thinking about. Particularly the incident where she was scandalized that he hugged her and gave her a kiss on the cheek in front of her husband combined with how upset she was that he'd thought about dressing as the devil makes me think this is a culture clash between somebody extremely conservative and somebody much less so.
Which makes perfect sense for documents. So why do we use a markup language suitable for documents for general data? Whitespace matters in a document, but does not matter for data. (I'm not accusing you, I'm actually curious if you know the answer. I've never had to deal with XML.)

Because of poor-but-good-intentioned and outright malicious reasoning about gender in laws.

I wonder if, over time, this trend will lead to a shift in what is considered acceptable writing. Once the "texting" teenagers of today take positions of leadership in government and corporations, they may be more accepting of this writing style.
The Kindle is great, I just don't use it enough to justify keeping it around, especially if I buy a tablet. If the Notion Ink Adam (http://www.notionink.in/) lives up to the hype, then I will buy it, and it's more likely to be with me. I love the display and the form factor on the Kindle. It just disappears in your hands and is great for reading. My problem is I consume so much more dynamic media (blogs, websites, etc) these days and a lot less static (books). More often than not I grab my phone than the kindle for reading, which means I read fewer books and more websites.

The Kindle is horrible for reading magazines. Navigation and skimming are stone-age, and there aren't any of the pictures that many of the magazines I want to read (I don't read physical magazines as they aren't conveniently located) are enhanced by.

The Kindle also is horrible for reading anything with footnotes. The "joy"stick provides anything but. Try reading a footnote heavy book (my particular example being one Oliver Sacks book) with the Kindle and you'll be ready to send a blank check to the inventor of the touchscreen.
I'm glad you were able to say that without fear of being attacked.

As for me, you can slander my person, my family, my dog, my culture, my religion, my property, my intelligence -- you can say whatever you want. I may disagree and be angry by your words, but I will fight to the death for your right to say them.

Freedom of speech means nothing if it comes with your right not to be insulted.

Whenever someone gets in trouble for sexual harassment, I like to find a picture of the perp. The funny thing is that you almost never see someone noticeably more attractive than average getting caught committing sexual harassment. And if you do, you find out that he's a serial harasser, with dozens of unreported past cases.

SNL had some fun with this: http://www.youtube.com/watch?v=gBVuAGFcGKY (moderately not safe for work, but no nudity).

It's interesting to have a law that says, not "X is bad behavior," but "X is behavior that you can only get away with if other people like it." It would be like having a law that banned porn of ugly people.
Or "Innocent as long as it fits into the agenda of the people deciding your innocence." (e.g. finding him guilty of sexual harassment would look back for the University)
When I was younger I was a pirate for one reason and one reason alone. Lack of funds. Now that I am older I take pride in supporting the developers and content creators. However, without the internet and pirate downloads I never would have gotten interested in graphic/website design or discovered so many great genres of music and film - which then translated into sales later in my life. I guess art and education tools should only be for the rich?

Ask HN: SEO Question - Domain-Based Versus Path-Based Site Structure?
Over the last few weeks we’ve had a brewing debate over the best way to structure a new site we’re working on from an SEO perspective. Basically, we’re planning for the site to become very big over time and want to make sure our structure is giving us the biggest bang for our SEO buck. Below I have linked to a post on our blog that outlines a perspective from a key member of our the team. Clearly a more descriptive context as to what type of site we’re working on could be helpful, however my question to you is this: which structure - domain-based (topic.company.com), path-based (company.com/topic), or a hybrid - will deliver the most value from an SEO standpoint? If you have an opinion on the matter, we’d love it know it! Thanks!

Are you familiar with python? Perhaps this will help:

if cnd:
return do_big_stuff
else:
return do_other_big_stuff

has different semantics than a hypothetical "if" function call:

def a():
return do_big_stuff
def b():
return do_other_big_stuff
return if(cnd,a(),b())

Note here, both "do_big_stuff" and "do_other_big_stuff" are evaluated, regardless of the value of "cond".

A short-circuiting if (only possible if "if" is a special form) will ONLY evaluate a() (and thus "do_big_stuff") if "cond" returns a truth-value.

Now, Factor's "if" works like this (in python):

return if(cnd,a,b)()

That's fine- and it still has the short-circuiting semantics, but there's still a question of taste here.

"Here's a list of some major PC software products. Do you know what they all have in common? They were first successful on Apple systems, and only later took off in the PC world."

Call me crazy, but maybe the PC is easier to develop for. At least the software listed there is still available for the Mac. When Apple bought Emagic, production of the PC version of their digital audio workstation Logic ceased.

I remember the year Photoshop's sales for PC were higher than Photoshop's sales on the Mac. More and more, the myth that Macs are better for creative software eroded.

Nonetheless, it does basically boil down to philosophical differences. I'm still a big fan of my iPhone and will probably even get the iPhone HD (or whatever), but Apple's made it very difficult for me to transfer that enthusiasm to anything else they do.
