Your instincts are correct here I think. If you're writing games then I suspect this is pretty accurate. You'd likely have to purchase a lot of test devices and do a lot of tuning to keep up with the hardware. Android vs. iOS game dev strikes me as a lot like the difference between windows and console game development.

If, however, you're writing basic apps like I am and using the standard development tools then it's a lot less of a hassle. I primarily write appwidgets (apps that run on the home screen). Theoretically these have could run into more fragmentation issues since various manufacturers have built their own home screen replacements and improved appwidget capabilities have been a focus in 3.x, 4.x. Yet in about 2 years since I started I've rarely hit a device specific issue and I'm supporting 2.1 - 4.x. I have about 3000 active users so not exactly large scale, but enough that if it were a serious issue I think I'd be hearing about it more.

I have two devices - a nexus one to test on 2.x/phone and a transformer prime to test on 4.x/tablet. Other versions I spot test in the emulator (admittedly this is awful). That's been sufficient for me.

I'm sympathetic to the technical difficulties of developing and maintaining a high quality game for the platform, but that shouldn't scare anyone off from developing regular apps.

Count me in the school of thought that the control key is meant to be to the left of the A key, just like the horn button is meant to be in the center of a car steering wheel. Every computer keyboard I worked with before the advent of IBM PCs had this arrangement. Every computer I work with now I reconfigure to swap the caps lock with the control key.

IT IS THE NATURAL ORDER OF THINGS.
I'm assuming they're making use of the fact that the iPhone is multihomed when wifi and cellular connections are both enabled. This means that any outboard traffic from iOS could take two routes, but the ad-hoc wifi network is only advertising routes to IP addresses in a (predetermined) private address space. So when the websockets app talks to a private IP address it choses the wifi route and when it talks to a public IP address it choses the cellular route.

http://en.wikipedia.org/wiki/Multihoming
And this is bad enough. There are plenty of services that could make anonymity and privacy as part of their offer, and laws such as this make it a moot point.

Worse, it touches defaults. By default, most sites don't keep IP addresses (no point really, for most businesses). Changing this opens so many possibilities for law enforcement, and they are all the kind I'd expect the chinese government to be happy about.
> That isn't correct,

Fair enough. But don't ISPs and other commercial entities tend to share that stuff "voluntarily" already?

> you could go and read the bill if you want

I like the part about "the term ‘Internet’ has the same meaning given that term in section 230(f) of the Communications Act of 1934."

It says "the term ‘commercial provider’ means a provider of electronic communication service that offers Internet access capability for a fee to the public or to such classes of users as to be effectively available to the public, regardless of the facilities used"

Why wouldn't that apply to a coffee shop that offered free Wifi?

Wouldn't they then be required to collect and retain information which "enables the identification of the corresponding customer"?

Are coffee shops and libraries going to have to check photo IDs like Iran and China?
Asher's Gridlinked supposed a limited set of society [operatives & wealthy] who could manage this fulltime connection, and even then it was perceived as unhealthy.

Wikipedia has undoubtedly changed how our generation views knowledge, but it's still a pull-technology. Outbound messaging will still be a push-technology (nobody wants to compose an email of their stream-of-consciousness, and brains are poorly wired to retain full structure in mental 'RAM')

Wetware doesn't add significant differences to the existing protocols - merely a more rapid input mechanism than checking your phone. Assuming contact is voluntary, people will not opt for the PubSub model for comms. If you choose to use it for trivia, caveat emptor.

Playn - Cross platform game library for N≥4 platforms - Google Project Hosting
I started off reading this essay a bit carelessly -- it seemed that pg was saying that these ideas are too nuts, and YCombinator would never back something like that. I was about to write a post completely disagreeing.

Our company for example is building a new type of social search engine, will in many cases replace email for messaging, AND long term have a third party platform that will enable websites to take advantage of our single sign-on and be instantly social, while safeguarding privacy. We have a patent application on this (yeah, I know...)

I don't know... all I know is, I am driven to accomplish this. And so far we've got some positive results.

"Look at a large enterprise org - you think that Lockheed with 150K employees would spend $50/yr/user on email?
Hell no. they dont spend 7.5MM per year on their email accounts for the employees."

Yes, I certainly do believe that any American corporation with 150K employees spends significantly more than $7.5mm/year on their messaging system.

These systems actually get _more_ expensive as they grow larger - Disaster Recovery, Business Continuity, Sarbanes Oxley, Customer Service, SLAs, Data Loss Protection, Intrusion Detection - All these email services that the small enterprise doesn't worry about (that much) - add up significantly in larger enterprises.

Ask HN: I'm an Economics prof. & I need your help teaching about SOPA/PIPA/ACTA
Dear HN,
I am teaching my introductory-level microeconomics students about market structure (perfect competition, monopolistic competition, oligopoly, and monopoly), and I am looking for articles that discuss the market structure of the media industry (preferably in context of SOPA/PIPA/ACTA). So far, I've read a ton of stuff that asserts that the industry is a monopoly (which it is not, btw) but haven't found a single article with any real analysis. I am certain such articles are out there and I just haven't found them. I am also certain that someone on HN has read them and can probably post a link or two for me. Thank you for your help!
you are vastly underestimating how much email has changed the world. if a better email can do for this generation what email did for the last one, i'll back it against anything on your list for sheer bang for the buck.

When I say it, I mean that I'm not fucking letting it break me.

Last year cancer ate my mom's brain. Knowing that it was almost certainly fatal, she still fought it all the way: surgery, chemo, radiation, and a host of complications. She may have died, but cancer didn't win. Even though more tests were the last thing she needed, she participated in a study. After she died in hospice, her body went back to the university hospital so they could take extensive samples for an astrocytoma tissue bank. I'd say that's a fine fuck-you to cancer.

It would certainly nice if nations stood together, et cetera. But if they don't, fuck them. Why? Fuck cancer, that's why.
Lots of stock option data - what do i do with it?
For the last several months, I've been collecting stock option data on roughly 3700 US financial instruments. That's about 200k rows of data per day. The project started on a whim, but is getting more robust and interesting as I optimize the data-collection process. It feels like I'm at a point where I can do something with the data - some basic information/data mining, charts, etc. but I'm not sure which way to go. Any ideas?

the prvt.org domain? the jester, who was the guy who first published that a year ago, tweeted that he thinks Sabu was arrested before the whois record on that domain was leaked.

somebody needs to sit down and work out the timeline here and figure out what happen.
Bloated frameworks, and software with many layers (some quite unnecessary) were facilitated by increasing clock-speeds - but at least it's possible to get rid of them. Also, work has been done on JS JIT compilation. Server languages are getting faster too.

It's instructive to note how much more compact alternative operating systems have been made compared to the mainstream ones. Full fledged BeOS systems used to weigh in at just a couple of hundred megabytes, with feature sets comparable to OS distributions taking several gigabytes. Also note that users of Symbolics Lisp machines used to be under the impression that the company had hundreds of programmers, and were amazed to learn that there were just 8.

A bit of bringing back Moore's Law could be done by getting rid of bloat. Perhaps the advent of the Raspberry Pi will allow this to happen.
Not sure what you are arguing here... if you are arguing that screening for cancer can be useful and saves lives, then I agree with you!

If you are arguing that a start up could have come up with a screening program for bowel cancer for example, then I don't agree with you for the stated reasons.

Also:
Prostate cancer screening is not recommended (http://www.cancer.org.au/File/PolicyPublications/Position_st...)

Breast cancer screening is not as useful as you would hope either. (http://dx.doi.org/10.1002%2F14651858.CD001877.pub4)
2000 women need to be screened for 10 years to save 1 life, with 200 initial false positives requiring biopsy. Also, I see lots of people diagnosed with breast cancer despite having mammograms.

Radical ways to do early detection are fine, but you have to prove that it works and that requires a lot of people for a lot of years and a lot of money.

Building a toilet with a bowel cancer screening kit built in is a form of behavior modification to improve uptake, and that is a great area for start ups to get involved in. pg was talking about something different however.

So, the link you gave me is nice and it says this: "Overall, though, the optimism among tDCS's believers remains high." I'm sure it is but my point remains regardless of the votes. This research is very sparse and the benefits are not quite that clear and the possibility that these fairly unclear benefits could be the result of some kind of mental priming or other the should leave suspicion intact.

Given the kind of claims being made, don't we need more than this?

OK. Fine. Wonderous possibilities - transhumanism and all that.

This is hardly a "proven" scientific thing and the benefits are somewhat murky. What I'm seeing on HN, surprisingly, are people talking about buying some contraption that purports to make them smarter and the CONSENSUS seems to be that that is entirely reasonable. Disturbing.

More disturbing I'm seeing comments about people experimenting on themselves with crudely crafted contraptions and hurting themselves and others simply offering advice about voltage regulators and the like. This is clearly a "sucker born every minute" territory." I'm really surprised to see this on HN.

I get the impression that I could post about some kind of startup in which I am going to disrupt biotech by curing cancer with some kind of Wi-Fi therapy and probably what I would get as a response is hints on how to optimize the timing protocols, reduce latency, and so forth.
Yes - I've done that to produce more portable Linux binary installers where static binaries would have caused other problems - I tested it for backwards compatibility, but hopefully it will also improve forward compatibility.

One problem that you encounter if you do that is that glibc has an option to disable support for older kernels in exchange for better performance, so you lose backwards compatibility unless you are very careful about how you compile glibc (it fails with an error that the kernel is too old).
> It's really hard to access academic journal articles online.

We obviously need something better than the status quo here, but the status quo isn't as bad as it seems if you know how it works.

Quick hints: email the article author. They'll probably more than happy to send you an article and a quick summary worded for a lay audience (not to mention talking your ear off about their more recent work...) They're not worried about you not paying the publishers, they want to spread their work around.

Another trick is knowing people in academia. Maybe you have a friend who's doing graduate work, or lecturing. You could ask your old lecturers if you went to university and if the paper you're after is in their field. There are also communities like /r/scholar on Reddit, though I imagine some people are against that sort of thing.
To me, this sounds very anecdotal; it doesn't match up with my experience (also anecdotal).

Remember, not all courses are made equal. I went to a tech school, and transferred after my first year to a high tier liberal arts school. I had a much harder time with a 050 level into liberal arts course my second year, than I did with a 400 level course on Poetry (of which I didn't have any sort of background in). I found the liberal arts courses at the tech school were aimed towards tech students - meaning, in that specific case, many of them felt somewhat watered down.

I would be willing to guess that, as a frequenter of Hacker News, you're more likely to be more active in a tech oriented circle. Growing up, and at college, I was more active among humanities oriented folk; my experience was that the tech folk were good at one thing (whatever they studied) and otherwise just played lots of video games, while the humanities students did every thing + 1.

So, all in all - my point is that anecdotal evidence is just that. Technical people can have a broad understanding, but it doesn't mean they do. Same goes for Liberal Arts.
A bit of nostalgia: Python.org in 1997
This is the crux of the problem with our current political system, I think. It's not campaign finance, it's not religion, it's not disagreements about economics, foreign policy, security vs liberty (a lovely false dichotomy) or what have you. It is simply the fact that lies win and truth loses. Or, if that statement is not necessarily true, it is true in the current practice.

I think Eric Drexler had hopes like this for hypertext before the World Wide Web started to hit it big. However, "In every age, in every place, the deeds of men remain the same."
For me, "coffee with Chuck" is #2 rather than #3 and yes, I want it in my inbox (maybe simply stay there until it happens, then archive it automatically).

Your other examples are clearly #3... and I don't need to read any of those emails.

Amazon confirmation emails are completely useless since Amazon always ships on time; in the exceptional case where a package doesn't arrive, I can go fetch the tracking number somewhere to investigate; but reading these for every package is a waste of time.

Mailing lists should go to a special folder labelled "things to read on a rainy day".

And finally "crap" is spam, no?

- - -

What about a service that would let you give a special email address for Amazon confirmation emails, for example, that would receive these emails and index and categorize them. When a package doesn't arrive you go there to look for the tracking number, but only then.

Of course you can do that with tags in Gmail.

What you can't do in Gmail is to generate a single PDF of all proforma received from a given provider, for example.

The CEO of that company, the "next Steve Jobs," might not measure up to Steve Jobs. But he wouldn't have to. He'd just have to do a better job than Samsung and HP and Nokia, and that seems pretty doable.

Some might say that Amazon is already doing better than Samsung, HP, and Nokia.
Also frighteningly ambitious is the prospect of any meaningful startup driven disruption in the energy industry. Which is a worry considering how desperately disruption is needed.

rπ is interesting because of its positioning as a learning platform equivalent to the BBC Micro which nurtured David Braben and many of the other backers. Not because it holds some magical quality over Gumstix, BeagleBoard, PandaBoard, CottonCandy, GuruPlug, DreamPlug, Arduino etc.
