I love random numbers for distribution. I had a similar problem with a set of distributed clients that needed to download email, but only one client downloading at a time. The email servers also had an issue where a large number of emails in the inbox would cause the server to slow down exponentially. (eg. it didn't matter how many MB of email were in the inbox but it did matter if there were more than about 1000 emails)

The downloaders would download the list of inboxes to be fetched, randomize them and then lock the inbox when they started downloading, then the downloader would randomly pick a size cutoff for the max email size it would download, 10K, 1 MB, unlimited with a n inversely proportional maximum email count so that about 100MB could be downloaded at anytime.

We even had an issue with one server behind an old cisco router that barf'd on window scaling, so a few machines in the pool had window scaling disabled and that account would naturally migrate to those servers with window scaling disabled.

It worked wonders for distributing the load and keeping the Inbox counts to a minimum.
Isn't that what the article says, too?

"Last week’s r17 developer tools release included x86 system images and host drivers (available through the SDK Manager), allowing the emulator to access the host CPU natively and offer significantly faster execution."

I just wonder, does this mean that the apps built on this version will only work on x86 devices and you need to modify the app later to work on ARM devices, too? Because if that's the case I probably won't bother with this, since 99.9% of Android units have an ARM chip.
No worries ;)
To be fair the facebook announcement was posted 10 minutes prior to the instagram.com post and so generated discussion quicker.

Sure, but the harsh reality of life often gets in the way of your lifestyle choice.

I've known several post-docs that have a wife and kids...and zero in savings because they only make $40k a year. Not everyone can afford to continue "doing what they love" when they have a family to provide for.

A lot of these people leave academic research to take up industry jobs where they reformulate cholesterol medication or research new ways to cure allergies.

I personally got out of biology because I enjoy software engineering just as much, but one compensates so much more in terms of pay. If I was making an equal salary in biology, there would be a good chance I would still be there trying to solve the world's problems.

So I suppose that's my point. Not everyone has the willpower, option or incentive to stay in a field they would otherwise enjoy working in, simply because of the timescale involved and the meager financial pay.
While I do agree with the author that FP has in-arguable benefits when it comes to optimizing for multithreading, I'm not sure I buy the logic pronouncing the full-fledged demise of imperative languages.

The notion that dev shops will switch to fully-functional languages because a junior dev is bound to muck up the code base seems a little far fetched. That's a huge price to pay for what amounts to a warm fuzzy feeling of immutable certainty (pun intended).
There is risk, but that's why you lessen it by diversifying your traffic streams, and even your income streams. I own multiple software products and web apps; if any of them tanks I still have more than I need to live on. Actually, at this point, more than one could totally disappear and I would be ok financially.

The odds of you selling out and making $5M are ridiculously lower, and I mean hundreds or thousands of times lower, than making a few small apps that generate a full-time income.

Instaport.me
It breaks SOME minifiers. There was some inlining tool used by some mobile ISPs that basically downloaded referenced JS files in <script> tags and injected them inline to get rid of another HTTP request. They broke, because they are stupid, broken tools.

A correct minifier works on the AST of the code anyway (at least in the abstract). It works on the semantic meaning of the code, so it interprets semicolons or the lack thereof exactly the way any other implementation would.

The first case with the broken inlining tool is typically not actually an issue, because your semicolonless code gets put through a minifier which probably adds a bunch of semicolons again :)

You need some serious perspective, they just got 2x return in a few months. They can, I don't know, re-invest the money perhaps?

And you're cherry picking out one of many Sequoia funds (and still a successful one at that) to point at to call VC life hard? A dot-com period fund as well?

Big pharma isn't ignoring it because of the patent issue, they are ignoring it because it doesn't work that well.

They may not be able to get a "composition of matter" patent on it, but they could get a "use" patent on it.

For a great example of a VERY common chemical that big pharma is developing, check out BG-12 from Biogen. It's dimethyl fumarate, something you can buy in ton quantities and most labs have jars of it. They are developing it for MS and it looks quite promising.

Who says that all new architectures must be easy targets of C? Perhaps this is part of the fun.

I am convinced that alternatives to C will produce much more compact programs.

I am enjoying the rash of assemblers, compilers, emulators that this architecture has generated. It is tickling an key aspect of hacking that has been underrepresented here on HN.
You can still post to Instagram without sharing the photo on Facebook. So this "paranoia" - if I may call it that - is only because Facebook now has acces to all of Instagrams information? And Facebook will abuse this position why, exactly?
I have considered it myself, but quickly dismissed it because, yes, the output would grow considerably.

I use American Express Plum. It's a trade terms card -- pay your bill within 10 days of the due date for a 1.5% discount on all your spending, or pay 10% of the bill and you have 60 days to pay the rest interest-free.

It's not a traditional credit card, you can't maintain a balance past 60 days... but there's also no credit limit. You can spend as much as your business needs. I've been given credit cards with useless spending limits; Amex let me charge over $10k in the first half month I had the card.

Amex has amazing customer service, and they'll FedEx 2-day the card to you and activate it on the phone with you as soon as you receive it. And you'll get all the benefits all Amex cards come with that almost no one else offers, from extended warranties on all purchases, accidental damage reimbursement, return protection to discounts on purchases at all the OPEN partners like OfficeMax, FedEx and hotels.

I think we can take you at your word that you are not trying to sleep with all of your female friends. Talking specifically about hetero males at the moment, for the sake of discussion, I hope we can all also acknowledge value for men in relationships with women beyond sex - "they're funny, interesting, loyal, give good advice, etc" as you mention, with the "etc" representing a huge list of additional items.

But the point is not whether you can be friends with a member of the sex you are sexually oriented towards, but whether you can be just friends.

Take your list of female friends and think about each one in turn. Please only include people that you invest in a relationship with, not just acquaintances or additional people that happen to be around or in your social circles. For each, assume that both you both have no social/practical/ethical/moral constraints keeping you apart (other relationships, for example). Further assume that somehow this person is the best reasonable prospect for a mate available to you. Would you pursue a romantic relationship with her?

You seem to suggest that you find some of your friends attractive. I can take this no other way except to mean attractive as a potential mate or sexual partner (though you don't intend to act on this in your current situation - that is understood). For those you consider attractive I will assume that the answer to the question is "yes", you would pursue her. I think we are getting into the definition of attraction here and I can't think of another way to look at it.

Are there any in your list that you would answer "no" to? Why? I suspect that an honest assessment would yield very few or not any "no" answers for female friends that a man has developed a friend relationship with beyond the acquaintance level. Am I wrong?

I think it is natural that the things that draw you to a woman in friendship probably correlate strongly with your list of what makes women attractive to you, so you will tend to be friends with women you consider attractive. Please don't read any suggestion of ill intent into this - that's not the point. Again, the point is that we are talking about whether you can just be friends. The sexual attraction and potential for romance, even if very theoretical, will often or nearly always be there and will color the relationship, perhaps even in a very subtle way. It does not mean you have any conscious sexual designs, but it is still part of the relationship.

> The NFL's revenue is not really a reflection on our priorities.

Isn't it reasonable to assume that, if costumers had different priorities and seek for science research news more often. Then advertisers would, maybe, consider investing in science research instead of football? If we could, somehow, teach and get people interested in science. Then having your brand name associated with the cure of cancer could be more valuable than having your brand associated with football.

It just seems to me that it's a matter of whose priorities are we talking about. You're not wrong, but I have the impression you and noonespecial are talking about different things.

Christine Herron's comment on this post seems to explain: http://techcrunch.com/2012/04/09/right-before-acquisition-in...

"It's common to use an impending investment valuation to drive a higher acquisition valuation. Strategic/acquisition values are typically much higher than investment values. eg, as of today, Instagram is worth more to Facebook than it is to Sequoia, because Facebook gets strategic value in addition to market value. Also note that an investor with a signed term sheet would be fully aware that acquisition discussions were taking place, as well as what valuation range they were in. I would be surprised if Sequoia did not go into this with eyes wide open. They win either way - an instant 2X multiple on investment (and a crazy high IRR), or a highly desirable company that they believe has growth potential. Call me jealous."

Nope. Android apps are, with one caveat, independent of any particular architecture, due to their Java/Dalvik base.

The only situation where anything developed on x86 would not also work on ARM is if you include native code via the NDK (which is not usually done except where you need to wring every last bit of performance out of the device), and that's just a matter of building the native code for all the platforms you intend the app to run on.

The platform used by the emulator image makes no difference to any of that, it just makes it a lot more practical to get usable speed out of it.

Well,

"Cancer isn't like a virus or pathogen that has evolved to avoid it our immune system..." until it start reproducing at a quick rate -then, as the article says "Tumor cells undergo evolution as they grow, so that the cells in them are genetically heterogeneous.".

But another thing to think about is that science based medicine has so far been more or less powerless against degenerative diseases - in general. Our treatments for cancer, heart disease, arthritis and so-forth as basically ad-hoc as contrasted with our treatment of externally-caused disease.

And this isn't surprising given that a degenerative disease is essentially a breakdown in engineering of the body and we essentially don't have a clue how to re-engineer or repair those processes (with many fine exceptions but they are exceptions).

The genetic diversity that the author talks about in cancer is basically present fully functional human beings. The way that different people function is far more different than even the way two different cars work. When human any part of a human being breaks down, we can't in general produce a replacement. Sure, there are advances in understanding the processes involved but these are, again, ad-hoc so far.
Not so sure about that. As people on the thread commented, the popularity could lead to better contracts. For example, wedding photographers get paid quite well. If there are so many "free" contracts, that itself is a valid reason to start charging for the next one: I won't do your work, unless you pay me -- sorry, I have too many requests, and need to prioritize.
I've got the photos-that-get-better-with-time problem nailed, but I don't think it can be as viral as daily-nothing apps. Nostalgia tends to be more individual; daily-nothing is entirely social.
Aside from the managed bytecode, when you build with the NDK you can target multiple platforms in the same APK.

e.g. (in the Application.mk)

APP_ABI := x86 armeabi armeabi-v7a

This app will run with gust on any of those platforms.
Huh? Same as what? We are talking about 0-day vulns. By definition if you think you have found a 0-day, you have little to compare it to.

Exploiting a bug on your system to verify that it is a bug that can be exploited would seem to be one of the very first things to do after verifying your backups, if you think you have found a 0-day vuln.

Otherwise, how would you know that it is what you think it is?

There is no general procedure you can run on code to check this for you other than actually checking it and seeing what it does.
I use a personal card for my business expenses - the purpose is to separate expenses not establish credit - the bank accounts and other bills can do that just fine.

I've seen the charge it and get reimbursed approach used at a Fortune 100 company and at every level between that and my business.

Obtaining business credit for a small business can be time consuming, and often provides little real benefit. Other than the annual fee, I've been happy with Amex.

Ask HN: UX expert advice needed
Hey, we are a bootstrapped startup (4 people, 3 developers and 1 biz-dev) currently preparing a prototype of a web based application. Because we think first impressions matter, we would like usability to be the most important aspect of our application (among other qualities as well).

Now because we have little experience when it comes to proper UX planning and testing, we kindly ask HN if there is any UX expert that would help us out mostly with pointing us in the right directions.

If anyone is interested, drop me a line to tomaz@carmivore.com

Cheers!

I love this stuff. I haven't had a chance to implement a summed area table yet for anything, but I did do variance shadow maps very recently (did you mean to cite that?). I did read about them though, and one drawback that I remember was that you might have a precision overflow in the bottom/top corner where the summations are the greatest?
I would like to throw some random thoughts:

1) It seems like people coming from Lat Am makes the most progress out of the program. Not only they get contracts from recognized companies and banks like Telefonica and BBVA, but they seem to find private investment after the program far more easily (Eg: Junar, Taggify, inbed.me, Safertaxi, Hadza, AgentPiggy, etcetera). Why? You can prolly draw your own conclussions as i don't have an answer just hypothesis.

2.- It is hard to find good developers that are fluent in English and if you find them they will be expensive. In the other hand it is a far easier to find good designers, business development employees/founders.

3.-While Chileans are shy and elusive the first time you met them, they are incredibly welcoming with most of the foreigners and WILL appreciate any effort you make speaking Spanish (even if its the most awful Spanish in the world)
It would be dishonest not to point out that despite it's utility to hackers, Scheme shares Haskell's unsuitability for production code. The difference is that Scheme is limited by its minimalistic standard library, not by a flaw in the language, and you can "upgrade" to a syntactically similar, but heavyweight, cousin such as Common Lisp, or Clojure, to get work done.

I wonder if there's something to this notion. Would it be useful to study the "standard" libraries of various languages to determine what constitutes "suitability for production code?"

Most likely, everything is relative to the particular application a shop wants to build.
Facebook's core feature, apart from the graph, is photo-sharing. Instagram is the only company at the moment who has any real chance at building a base to compete with Facebook on photos right now. Looking at this from a $/engineer or $/user seems misleading. I have got to imagine that managing future competition motivates this move. That being said, it seems absurdly expensive.

I'm surprised they didn't try to add photo-filters to their mobile app first. I don't think people are going to spend the next decade taking retro pictures. Just like with location - they could've added the feature to their app, people can "be part of location" without having to join a new network.

Over time, most people get bored of filtering their photos and move on. By putting that feature in mobile app, Facebook likely could've done a bit put the curb on Instagram from ever pivoting away from filters into a full fledged photo-sharing network and saved themselves a billion.
This is great. Can I quote you?

Flickr is still big in numbers but has more or less gone south for a lot of users, and Instagram may have filled this gap.

there's a lot of people that wouldn't fit the bill for facebook friending but are perfect in a looser setting. In this perspective, even if userbase has overlap, I'd guess that the social graph on Instagram is radically different than the one on facebook for a lot of users.

Now depending on how much Instagram gets integrated into fb, that might become less and less the case and give an opening to another photo sharing service...
It's a prototype (meaning the website is not coded yet, no comment system etc...).
