Hi, would love your feedback.

We've been concentrating on making a system so that remote parents and long-distance relatives can stay in touch with what their kids/ grandkids are doing on mobile devices.

In our early user-research, it transpired real-time tools (Skype and Facetime) weren't that great because schedules didn't coincide. Any tips on UX for late-adopters welcome :-)
You are ignoring the energy in the fuel. Which is arguably a reasonable thing to do as we don't have great fusion reactors yet and H Bombs are not exactly sold at Home Depot. But, it's still the kind of fuzzy thinking that leads you to assuming bad ideas will work.

As to 100W vs. > 100W. 100.001W might as well just be 100W in just about any meaningful way. However, Jet is vastly cheaper per watt of liberated fusion energy. https://en.wikipedia.org/wiki/Joint_European_Torus

He's arguing against those who have tried to make advancement of marriage part of public policy as an anti-poverty measure.

The math stuff is just to prove that, as a policy measure, it's nonsense.

John Gruber needs to feed and house himself, his wife, and his kids. I'm just guessing here, knowing nothing about the internal workings of the company, but I'm pretty sure Imgur has a few more mouths to feed than a single founder's immediate family.
Could be a problem with how ST reports its project names to the system. I'll take a look soon, sorry about that.
Thoughts app, sketch in infinite canvas, is now free
Just like in real life, all kinds of people can be equally reprehensible to each other. It just varys in the ways. Men are typically assaultive, with in-your-face accusations and threats. Women often use exclusivity and shame as a weapon in equal parts. Because men are typically louder and more violent in their abuse, we tend to register it more often.
Hello! I just want to let you know about Thoughts, a sketching app for iPhone and iPad + Pencil.

The cool bit of the app is that the engine is vector-based so basically you can zoom in and out and the image remains sharp.

Please take a look and ping us if you want to know more about it.

Thanks!
Can someone who uses Snapchat routinely tell me why you use it routinely?

I've been using it for a few weeks to send a picture or two to the few people I know who use it, but it seems pretty limited. I follow a few "famous" people on it, and they basically just post random images of them walking around NYC or them traveling. I don't yet see the benefit.
Please, I can see you don't know what you're talking about.
I'm not a fan of Facebook, and I think their core product is fundamentally antisocial and creepy. That said, the company is hugely successful. There's no denying it.

While Facebook may be less hip than it once was, the company now owns mobile (Facebook, Instagram, Facebook Messenger, WhatsApp). They would have loved to had Snapchat too.
I don't see it that way at all. I think the sort of casually calling other women slags and hoes or whatever (ie normalised internalised misogyny) is a very different ball game to the gamergate style evil shit that happens.
Is it only for OS X?

> You haven't considered 2 things: marginal returns and opportunity cost.

Yes, I have.

> this overlooks the millions of hours spent in C systems

No, it doesn't. You are assuming that I am advocating re-writing existing C code in this hypothetical new language. I'm not. The hypothetical new language should be backwards-compatible with C, either a superset of C (like C++) or with a C (and C++) FFI (just about every other language out there today).

But even that is not strictly necessary. It is already common practice for programs written in different languages to interact with each other via language-independent mechanisms like pipes and sockets.

> If the better language already existed, and was a drop in replacement (meaning everything just works) then your argument would indeed mean an end to wasted effort if adopted.

Many such languages exist. The one I like to use, Common Lisp (and specifically Clozure Common Lisp) not only has a C FFI, it has an Objective-C FFI, which allows me to easily write Cocoa applications and leverage all of the power of both C and ObjC libraries on OS X with all of the efficiency of C. No wheel-reinventing required. And yes, everything Just Works. (With QuickLisp it really Just Works!)

> But as it is, it means tons of EXTRA effort

No, it doesn't. If you think it does, then you're doing it wrong.
Tycho Brahe was wrong but on stronger scientific ground given the observations available

Depends on how much weight you place on different lines of reasoning.

One of Galileo's key insights was that there's no fundamental difference between the terrestrial and the celestial. In contrast, the Aristotelian heavens are made of aether, in part to be able to account for the diurnal motion of far-distant planets and stars.

Alright, touche. Facebook is actually worth what the market claims it to be worth, because of the large amount of people in one place, all willing to tell the world exactly what their interests are. Its a marketing heaven.

Snapchat might be worth a lot, but I'm just sick of companies like this being valued so high, simply because they provide literally no benefit to society.

If Snapchat went down tomorrow, would it really affect anyone? Nope, the World would keep on spinning.

It's time to incentivize people to make a difference, not build photo sharing apps. There are real problems in the world that desperately need to be solved, yet we're getting rich off dick picks and calling ourselves the "innovator of the century." Yeah...no thanks.
I agree that we need to be careful when talking about online abuse to distinguish between name calling, vicious name calling, and then threats of sexual violence or other violence. And I agree that at the severe end the perpetrators are probably mostly male.

But for one example of a woman making these extreme threats of sexual violence: one of the famous cases in the UK is the Caroline Criado Perez trolling. Two people went to jail because their tweets were so threatening and one of those people was a woman.

http://www.independent.co.uk/news/uk/crime/twitter-trolls-is...

She got a longer sentence, because her tweets were more extreme, than the other (male) perpetrator.

Ask HN: Should I work in the US on a tourist visa and get paid via PayPal?
I'm working with a company for a few months remotely, and now they ask me to come aboard to states and work from there for a few months. But they can't sponsor a J-1 work (internship) visa and I only have a tourist visa (B1/B2) valid for a couple of years from now.

Should I move to the states for a few (2-3) months as a friend/visitor and get paid via PayPal or some other means?

What are your thoughts ?
Thanks !
Was this updated recently? This has been up for awhile.
I apologize - I did not notice the slight variance in spelling and made a hasty assumption.
That wasn't ranting, it was cogent and well-structured and made good points. If you disagree with those points, say so, but don't diminish it by calling it a rant.

I think those points are extremely relevant for an article targeted at people trying to get involved in open source. The for-pay vs. free-time divide is a fundamental problem with using open source work as an "in" to the industry, and despite being scoff-worthy to some people, it's helpful for people coming into this with fresh eyes (ie. the target audience of the article) to be given some context.
Many people do. S3 is convenient though. It handles durability, replication, uptime, etc... and even with the insane markup on bandwidth many startups / companies can afford a $10k/mo bandwidth bill because it's cheaper than hiring some devops and a team to build out the appropriate infrastructure.

I also really liked this article but found that bit orthogonal. Thought that comes to mind is like clean code an essay should ideally do one thing and do it well...but if it has to do more than one thing, it should do what it says. I'd suggest splitting the article into 2 (["So You Want to Be a (Compiler) Wizard", "Contributing to Open Source Compiler Projects"]) or if not that then update the title "So You Want to Be a (Compiler) Wizard; Plus Thoughts on Contributing to Open Source Compiler Projects".
It's more immediate than a text, less intrusive than a call. With a snapchat, you're more likely to open it and respond quickly than a text message, because just like the time limit on images, once the time has passed, the moment is gone. It keeps you hooked in.
I'd bet a shockingly high percentage of however they're defining 'online abuse' - is specifically middle to high school age girls targeting other middle to high school age girls
People need to stop focusing their criticism on how stupid the app is or how they're going to lose all their users. It's almost a meme by now of how people say this every time Snapchat is brought up. By now it's a foregone conclusion, and requires active ignorance and not really caring to keep an open mind, to continue to hold onto that belief in the face of tremendous evidence that 1) Snapchat is very popular, 2) Snapchat has been around for 5 years now and hasn't gone anywhere, and 3) Users of Snapchat use it very actively.

Personally, I think one good way to see why people use the product is to 1) be in a relationship, and 2) regularly send pictures of what you're doing / funny things you've encountered / your face, back and forth with your partner.

Where I feel like there is legitimate criticism of Snapchat is their ability to monetize. Unlike Google, there is no purchasing intent. Unlike Twitter or Facebook, there is little ability to target users beyond age/gender/location (and no amount of computer vision in the short term will change that). Their Discover / Live products (which allow you to see snippets from brands / news channels / publishers) are promising but unlike the core product, I think there is legitimate reason to be doubtful about the appeal of these products because they have nothing to do with chatting with friends.
An GWT engineer and former Scala guy, Lex Spoon, proved a similar theorem several years ago when we were upgrading generics for GWT-RPC. The GWT RPC code generator has to reason about return types of methods and which classes could possibly be deserialized say if you return a List of Foo.

Lex showed how to construct the peano arithmetic in Java generics and how to formulate problems such that solving the question of what types could be returned from An Rpc call with List would amount to deciding these small theorems or problems and therefore the GWT SerializationTypeOracleBuilder class would have to solve the halting theorem.

That's probably a wrong paraphrasing and maybe lex will see this and chime in but I think the original discussion was lost forever ironically when Wave, which was built with GWT, was shut down.
Yep. The GitHub readme says Windows and Linux are not supported at this time.
Eh, considering that TCP support already exists in the standard library, I could see HTTP also being added someday if there were sufficient demand.

Bignums in general are a bit too open-ended, but I could see bigints at least being added someday.

And as for async io, I think it's the same story as with HTTP: imaginably included contingent on implementation maturity and user demand.

>The media singling out a group such as the Chinese visa students is certainly a popular thing to do to gain clicks, but it's a little unfair.

Did you bother to read the article? There is a cheating industry that caters to the Chinese. This is a valid topic to write about. I think going full politically correct just makes us all stupid. This industry exists for a reason; there's demand from the Chinese and this most likely ties into the ideas of success from Chinese culture where cheating and copy is tolerated, if not encouraged.
To save you a search query, Facebook today has a market cap of $342 B (this 2010 article says they're not worth $33 B).
Sounds fishy. I get that sneaky OS updating is unwanted, but it can be avoided and there's an easy 3 click process to roll back if Windows 10 is installed.

Don't forget that Apple now enforce mandatory iOS updates, with no option to opt out or disable the annoying reminders. Even if you have automatic system updates turned off, the point release iOS updates are downloaded without your permission in the background when the phone or iPad is charging. These updates might be between 80 - 300 MB. The notification dialog boxes then begin their attack, every day with two options "install now / remind me later".

This is actually worse than Windows, since on Windows we at least have the option to disable the scheduled update and the reminder notifications. Not so on iOS as of version 9.

A month from now there will be a debate/argument in HN comments about women being harassed online, someone will claim something along the lines of most online insults toward women are posted by men and someone will link this article. Tune in to next month's broadcast to see who gets down voted into oblivion, the person making the unsubstantiated claim or the person rebutting it.
Anyone know where we can download the leaked pitch deck?
"if I could prove someone broke their oath with knowledge, what is the legal punishment offered?"

I think you answered your own question. It depends on who that person is and whether the people in charge like what he or she does. Manning gets 35 years while Cheney goes free. The answer, to be clear, is impossible to know. When charges and trials are dished out arbitrarily like this, the idea of the rule of law becomes completely laughable. It simply boils down to arbitrary persecution of people for arbitrary reasons, no different than a king or other authoritarian tyrant's rule.
Why in this kind of sites, there is not a single person behind the marketing site? What's the reason to be hidden?
I've given up on Jolla. Their OS got worse with every release. Their hardware was very sloppy (three dead batteries in a year time, design flaw which required me to keep a piece of paper under the battery to keep it in place). Their support was god awful. The only way to get my device fixed was to mail it to Finland and spend over a month without a replacement.

The idea was great. They tried to keep the Maemo spirit alive. But they failed.

Every single person here seems negative about Snapchat.

I am 30+, use it occasionally, and see more and more of my older friends signing up. Especially those friends far away from the echo chamber. This fundraising feels smart for investors who want a great return and for the company to use to get to an IPO.

If you don't use Snapchat, or haven't used it in a few years, it is probably time you take a second look.
Is there any research that show being peer reviewed in fact makes a difference? General speaking, I would think research should just speak for itself.
There is no system without logging in,the login via facebook or instagram is crucial to the process.I have a demo, actually is more than a demo but for now i am trying to figure out how to turn it into a business and not just a game.Almost every social media user wants his uploaded photos to be nice and some social media users are actually making an effort to maintain a good image but who cares so much that he would pay? When i first had the idea i made a research and found something similar but different.It's called photofeeler.People judge photos based on how trustworthy the person in the photo looks or how smart etc.On the other hand i say people if based on their previous photos they make a good or bad upload,i give them an estimate of the number of likes they will get.It's like reading a review for a movie from a magazine and listening to a review from a friend of yours that you know he has the same taste as you.It's completely different.
I'm pretty sure programmers will be replaced by AIs at some point - it'll just take longer than truckers or welders.
Don't forget that lots of people said Facebook wasn't monetizable either, just a few years ago.
I read it as an article aimed at people who want to get into open source for the first time, specifically targeted at compilers, because that's what the author knows. Like it or not, the social aspects of open source communities is very relevant to that target audience.
It checks the site immediately when it's added, then once a day afterwards.

The sentiment of http://issnapchat.deadyet.lol/ is amusing, but I agree it shouldn't be with the dead-product-walking list. Will add something that can filter or move these.
Which "n word"? Do a simple twitter search with the two spelling variants and you'll immediately notice completely different results.

Half of the article is sensationalist and bashes OpenBSD for bashing's sake. The devs are right about 90% of the time; they'd rather do something right than jump on the bandwagon and ride the hype off the cliff.

Yes, that's exactly what you'd expect from OpenBSD, now, in the past, and hopefully for many more years in the future. Years and years and only two remote holes.

Thank you OpenBSD!
It was a foregone conclusion that he would win the nomination after Cruz quit, but it's still interesting that it happened before the last big primaries e.g. California. Indeed this may affect turnout in the California primaries: GOP down, Dems up. The Dems may be charged up a bit to rally behind the leading candidate to counter Trump. But, we'll see next week.
Gross.

In a private environment squashing history is the precise opposite of what I want. I want immutable history. Anything anyone every checks in is there forever. Safe and secure. Impossible to lose. Impossible to screw up.

Furthermore, I want all the changes they made along the way to their feature. Because lord knows there will be a moment down the road where there's a line of code that doesn't quite make sense. And I'll want _full_ history to understand where that line came from. See how it evolved.

Git still doesn't have anything as good as p4 timelapse view. Which is deeply unfortunate. That's a great tool for spelunking the past.
One terrible way that bad professors try to enforce students attending their class periods is by sprinkling in "clicker" quizzes into their lectures. These are little four-button devices that you have to buy/rent at exorbitant rates from the school IT department. One class that I took, informally known as "Stars for Stoners" aka Astronomy 101, based something like 10% of the total grade on these clicker questions. Naturally, people found ways to circumvent this kind of bullshit[1], at least for a while...

Looks great! The interface picture, halfway down, should be the top one – it's too hard to tell what the app does from the first one. Might give it a try.

Yes. Otherwise you'll end up with an ugly Python or Perl script that generates code, coupled with ugly build system hacks to make it work. This will happen sooner or later.
We use feature branches, using atlassian stash rather than github.

I'm confused though -- I thought that if you rebased & squashed something after you pushed it, then it would confuse the git clients of anybody who had pulled before the squash?

Thanks so much for all the suggestions!

More better answers.
Tokyo and Mexico City have very, very few buildings over five stories and still have double the density of SF. Paris and Barcelona have almost none over seven stories and have four times the density of SF.

So it doesn't have to be high rises and skyscrapers. SF can look like SF and build enough to make living affordable.

Of course, the real problem is the peninsula cities that insist on densities much lower than one third of SF. 80% of buildable land on the peninsula is tied up there being wasted.
That's a symptom of capitalism. When your sole objective is maximizing profit, all else be damned, there is no such thing as working for the greater good or solving any of the critical problems we need to solve to keep our species moving forward. You get photo-sharing apps.
