Hardest and most rewarding was all the serious engineering we did to make the app and gestures fun and fast. Most of the components in the app are custom, from the navigation controller to the story menu down to the scroll physics. Aria just answered this Quora question that goes into some of the details.

If you have any particular things you'd like us to elaborate on, we'd be happy to answer your questions.
This makes perfect sense... I could easily see how a chemist could come to one conclusion, whereas a biologist would come to a completely different conclusion. In this case, I think the judge's chemistry training actually worked against him.
Before we pursue this metaphor too far, some observations about the National Electrical Code.

One is that software is many orders of magnitude more complex than an electrical delivery system. People have spent decades trying to figure out how to construct secure software by bolting together "secure components" in a simple way. Let's be charitable and just say: That work continues, and will continue throughout my lifetime. It's a much harder problem. Electricity is easy.

The other is that even the electrical code doesn't provide strong guarantees against malicious attacks by hostile humans. That's not in the spec. There's no armor on the wires that come into my house, no alarms that would go off if a ninja with a saw started cutting down a crucial utility pole in a DoS attack on my power, no formal procedures for screening the wiring in my walls for wiretapping devices. The electrical code doesn't even mandate a backup battery or generator, let alone that said generator should be tamper-proof.

Similarly, the fire code doesn't specify that my smoke detectors should have locks so that those ninjas can't easily remove the batteries before setting off a gasoline bomb in my living room late at night. There isn't even a gasoline-fume detector in my house. The windows aren't armored. This place is not defensible!

Of course, there are places in the world that are built at great expense to withstand attacks by armed bandits or trained spies. But if we wrote our building codes to incorporate such measures, what would happen is just what we see happening with software: People would line up to sign waivers and variances, so that they could just build a simple inexpensive house and get on with their lives.
As a recruiter I can provide advice on what I look for... Even if you cannot provide examples of your work, if you can explain what you can offer then most people can determine your skill level through coding exercises and just talking through examples. Hope that helps!
Awesome. Again. Another keyboard implemented for an OS where you can't even use the damn thing.
This seems to be a pretty common story around aqui-hires. I've heard of very few instances where two separate companies can mesh successfully after an acquisition. If nothing else, it makes me pay much closer attention to company culture with potential new employers.

For better or worse, company culture will have probably the largest impact on whether you enjoy your job - even more than tools/programming languages/hardware/etc.
Agreed. This may have replaced Sinatra for my go-to for building quickie Rest APIs
How could having nearly 2 hours extra each day NOT improve your QOL? That really surprises me.

Yes, new native Facebook iOS app is faster
This HN meme that all companies should be like Apple is getting a bit ridiculous. FB has always been an efficient engineering organizing that pushes out features constantly. They don't derive their value from their UI nor have they ever. There is no reason for them to start copying Apple now.

FB users don't use it because of the slick interfaces, they use it because of network effects. For that type of business, adding features fast (to create more lock-in) > focusing on great UI.
Ask HN: HTML5 Mobile apps that work?
I am in the middle of a new project where we need to publish a new mobile app. We are a team of pretty good js web devs, so we went with the (for us) obvious choice of cordova + jQuery Mobile.

We implemented a prototype with most of the features we would like to use in our finished product, and the app does what it has to, but animations are very slow, and using the app just feels "wrong".

Should we ditch jQM and switch to something else? Has anyone of you experience in building a Hybrid app with HTML + JS with any framework where the result was a bit better than acceptable?
In this case, the level playing field between Olympic athletes is that they have all four limbs and normal (or above) coordination and muscle capabilities. In the paralympics, I would consider a level playing field to be one where all the athletes were injured or disabled in a similar fashion. If one athlete is able to automatically raise his/her heart rate while the rest cannot, this is not a level playing field.

Although it is an inspiring story to see athletes at a disadvantage even considering their competition in the paralympics still out there training hard, focusing on their personal goal, and succeeding where their fate has previously told them they cannot.

DebtRank: a PageRank-like measurement of systemic financial risk
I appreciate the use, but in this context I think the word you're looking for is "emblematic."
I actually just bought your book. Looks like a steal for $3.75. The reason I bought it is because in your blog post you seemed genuine and like you put a lot of effort into. $3.75 is definitely a no-brainer as well. Also, learning from someone who is smarter than me but not someone who runs a company like Zappos is probably a more realistic and practical way to learn and apply the knowledge I gain :)
Cars and planes aren't under constant bombardment from invisible human adversaries all over the world. They're required to withstand failure in the face of known natural conditions and flawed workmanship, but not constant attempts by human adversaries to break them.

And an example that proves the rule - we don't sue car manufacturers when their lock system fails to prevent a thief stealing the radio or the car.

And, should we hold military vehicle and fighter aircraft manufacturers legally responsible for damage to their products by enemies shooting at them?

If a delivered software product doesn't meet a contractually-agreed-upon spec, then there is legal recourse for that. Maybe software contracts should specify exactly what penetration attempts it has been designed to withstand, and in very specific, not general, terms.
I have bluetooth off on my Air and it still has this wifi issue. Its some race condition because it doesn't happen all the time and for it only happens when waking up from a deep sleep(ram persisted to disk).

I guess I'm still missing it. I think measuring economic deals in dollars is pretty sensible. I'm not implying the terms of the deal have changed, however the value of the deal has changed MATERIALLY since it was announced to approved.
I'm impressed with how quickly FB, able to transition from emphasizing their web experience, to emphasizing their mobile experience. Most established web companies are moving much slower on this (ie Microsoft, Google, Yahoo!, Amazon, eBay, Flickr, Yelp, Craigslist, Tumblr, etc...).
The app is great.I can easily see myself using it daily. One feedback though -- while the ios app is incredibly fast and slick, some of the gestures and menu is not intuitive enough. Like - where are my settings (twitter/fb etc.) ? Can I change my email / password ? I guess others are providing similar feedback below and I hope that some of these 'small' things improve in the next version. Great app though !!

Half (or more) of Microsoft's business, and far more of their profit, is two product lines: Windows, and Office.

They're also synergystically linked: if you're running on Windows, you're far more likely to want/need Office, and if you're using Office, you're far more likely to want Windows.

Crack either side of that diptych, and you've vastly undermined the business. Apple is attacking both. The OS through both its laptop and desktop (yes, you can still buy desktop Macs) offerings, but increasingly, mobile (iPhone, iPad, even iPod). Apple iWork is a competitor to Office, and some products (notably Keynote) are vastly superior to the Microsoft offerings.

Apple's not the only competition, of course. Google appear primed to take on more of the space as well (Google Apps, Android). And there's even Linux on the desktop. One of these years.
They also sell lots of Angry Birds merchandise. Clothing and plushies and pencil erasers and coloring books and keychains and usb drives and multitudes of other branded products.

Not having a nasty commute would surely be an improvement, but the social aspect of working face-to-face with your coworkers has a morale value as well (I've found).
I don't think so - putting "WITH FIREWALL" and "SHIELDS YOU FROM EVIL" will cost manufacturers maybe a few cents and is almost guaranteed to boost sales.

And for services running behind that router there'll probably be some kind of PNP port opening (so there can be "PLAY WITH FRIENDS EASILY" next to those other stickers)
Do you know if they plan rewrite those also?
I think that staying HTML 5 is a mistake. As the needs of your app expand, there will be a greater and greater need to use native API's. The longer you develop in HTML 5 the more code you will have to port when you finally do decide to transition to native. You're better off minimizing your pain and transition to native early when there is less code to port.

I don't think the Python community in general dictates the use of buildout at all. I reckon there are more supporters for pip install -r (although I would take correction). So the question becomes, why some smart people consider buildout Pythonic. I guess they just like it.
Honestly if its bad for iPhone and android it's just to feel horrible. You might be to base on iPhone though. I suggest just swallowing the bullet and go native or at least titanium mobile.
You're obviously right that "emblematic" would be clearer writing.
The dozens of different Windows versions, the fact that their new flagship tablet ships in two versions with incompatible instruction sets, where one will only run "Windows 8 style" applications, and that the operating system itself has two completely different user interfaces that doesn't interoperate well. Actually taking the Kin to product launch instead of killing it off internally and refocusing efforts at a time when Windows Mobile was losing market share.
It's interesting that you say that because I have the opposite experience. When I'm at the office I find that people around me talking causes a significant distraction. I use noise-canceling headphones almost all day at work just to block out the noise.

In addition, I sit right next to a QA guy that works on my product and I can easy waste half a day dealing with his issues and questions.

I find that I get significantly more work done while at home because I don't have the distraction of coworkers tying up my time. I also find I tend to put in at least an hour more a day because I work when I would normally be commuting.
As dbarlett pointed out, the sub-vocalization is a big part of it, but once that's gone, there's still a long way to go to read quickly and effectively. I learned to read exceptionally fast, but had a very low retention rate of what I read (I use those techniques when typing), it's symbol recognition/word recognition, not real comprehension. I eventually slowed down my reading, but followging a rhythm (per-word rate) and process/think about/determine application for what I've read up to that point. In the end, reading quickly hadn't been as beneficial as being able to have a strong working knowledge of what I've read after only the first read through. However, I dislike reading fiction and don't prefer reading stories, an in depth whitepaper or textbook is my enjoyment reading, so learning as I read was more of a priority than just getting the high level view or enjoying the story construction.
The copy on this article and the book page itself feels so spammy that I would never buy the product. I respect the desire/need to make money, but I do think a certain percentage of your potential audience will be turned off immediately by the excessive use of this type of obvious marketing-speak (excessive use of bold fonts, short, pointed sentences, all the vague truisms, "money back guarantee"..). I hope this doesn't become the standard type of post on Hacker News, I'm sorry but after clicking on that link it really feels like I've just been spammed.
CBO: 2013 Projections - Coming recession with 9%+ Unemployment
Interesting initiative, but I see many issues in the study:

- As others have mentioned, it is not generalizable to other types of jobs. Call-center work may be improved when working from home, but what about other types of jobs requiring more interaction/communication

- But the biggest issue I see is with their mention of a "Randomized experiment". Well, technically it is randomized among those who volunteered for the experiment. So from a causal inference perspective, the results generalize only to the population of employees who volunteered, not to the entire company.

More generally, one of the problems with these types of study is that the best it can give is an average gain from home working. But suppose the gain is null. It doesn't mean that this is not a viable option. Maybe there is a huge variance in the gain, depending on the individuals: maybe the gain in productivity is huge for some employees, while it is negative for some others. This could depend on the employee's self-discipline (whatever that means), his family situation (single/married, how many kids), where he leaves, is he introvert, etc... A useful study would be to randomized the assignment, stratifying by according to these covariates, in order to learn more about their effect on the performance of the employees.
This headline doesn't pose a yes/no question. More generally: at this point, do you still think it's helpful to remind people of this Wikipedia article?
Similar to GluePHP: http://gluephp.com/documentation.html
Similarly to rhizome, I appreciate your use of a word I hadn't seen in a long while (and that HN spellcheckers flag), and I agree this is much more interesting than the article, but I would have gone with something in {emblematic, symptomatic, representative}.

I'm holding firm in claiming that synecdoche should be reserved for referencing oral or written expressions, viz., intentional usages of a part to indicate the whole.

Thanks for a little diversion :)

I've been running W3Counter for around 8 years. A fraction of 1% of its users pay anything, while a significant number of people log in to the site multiple days a week for years. They obviously find it useful, but they have no reason to pay.

> If they find your service truly useful, they'll pay without question.

If they find your free service truly useful and it meets all their needs, why would they give you money?
Yes. IE was "small" (being closely tied to the OS) and fast.

But the only reason MS gave it to us was to destroy Netscape.

Over the years there's no doubt been countless conveniences and innovations that MS could have introduced but didn't. They do just fine without having to share the products of their extensive research. That's the beauty of a monopoly. You do not need to innovate. You only need to keep delivering (just change the version number and some UI stuff) and you need to stifle any competition, early and often.

But those days are slowly coming to an end...
As someone who has mostly worked from home for the past decade:

1) Really long commutes for the sake of my butt keeping a seat warm to keep a manager happy are dealbreakers. I have never made such a job work out for me. At the most recent example, my brief position at Google involved a 1-hour commute each way only to spend 8-10 hours in a dead-silent office, where no one significantly interacted and for which I was forbidden to telecommute by my mostly absentee manager, ever. Loved the food and the gym though.

2) Working at home 3-4 days a week is productivity Nirvana for me leading to patents, promotions and pay raises lather rinse repeat.

3) Working utterly and completely from home eventually leads to a sense of isolation and depression.

4) Despite #3, I prefer to do crunch mode work in isolation because I'm easily startled and prone to the excessive use of colorful metaphors when under the gun. My cat doesn't mind. My dog doesn't care. But I suspect coworkers in proximity would fear for their lives.

> to PHP (again, huh?)

Were you not aware that Facebook is a PHP shop? Or are you just questioning its inclusion in the app's credits?
The word "synecdochic" exists and you can use it in this context, but it's a matter of lightning and lightning bug. Isn't the word "emblematic" more appropriate? We're not just using a part to signify the whole; we're stating that the part typifies the whole, and "emblematic" embodies both of those meanings. Besides, it's less likely to confuse, and applying Occam's razor to language, the best word is the simplest one that most closely approximates the intended meaning.

Ask HN: Does Google consider .../somepage/ different from .../somepage?
We have recently migrated our system from PHP to RoR.

However, in our PHP implementation, all URLs were of the form:
http://somedns.com/hello-there/ and redirects the pages with a 301 without a / to the /.

(e.g. http://somedns.com/hello-there -> http://somedns.com/hello-there/)

Whereas, our new RoR implementation is of the form:
http://somedns.com/hello-there and redirects the pages with a 301 that end in / to the no /.

(e.g. http://somedns.com/hello-there/ -> http://somedns.com/hello-there)

Will Google understand that both pages are still the exact same, and leave our SERPs in a good place, or will we lose our SERPs due to the change in trailing /?

If Matt Cutts, a Google Search Developer, or an expert SEO/SERP HN'er could chime in that would be incredibly greatly appreciated.

Our team members are split 50/50 on whether or not this would affect SERPs or not, so it would be great if we could hear some opinions, thoughts, comment, complaints, criticisms regarding all of the above.

Thanks in advance

When you start capriciously kicking various people out of your bazaar, it's reasonable to ask why you are destroying yourself.
Who says Facebook needs to be like Apple? No one is arguing that Facebook needs to change or make their UI better than it was or that it was even a feature they cared about. The issue was the experience delivered by the client they had out, which sucked. They picked a technology which everyone knew would be slower in order to make it easier on their mobile team. Instead of investing in an Android team and an iOS team, they wanted to make the code portable. Sadly using a UIWebView comes with zero benefits on iOS and Facebook suffered for that. They should have kept their native client in the first place. The point of using a web view is so that you can rapidly prototype features and UI, and as far as I can remember, Facebook did very little of that on mobile anyways.
Patenting a method to isolate the genes would be okay; but patenting the genes themselves; holy shit!
I'm the developer of Haiku Deck. Chute is powering a core piece of our functionality, and they've been a joy to work with. Our early beta testers were asking to import their own images from their device and existing online albums like Facebook and Instagram, and with Chute I was able to add that functionality to our app in less than an hour. We're a small team, so it's incredibly helpful to use tools like Chute as leverage points to get our v1 app in users' hands as quickly as possible.
