Not hard to imagine but very hard to do. There are several huge challenges:

- Power. Contact lenses are too small to hold batteries that will last for a reasonable period of time. You could possibly use inductive coils in conjunction with regular eyewear but that means a fair electromagnetic field aimed right at your eyes and some obvious health risks.

- Optics. This is actually 2 issues - First, you can't focus on anything that's literally right on your eye so you'd need to do something very clever here. Possibly direct laser projection from the lens to the retina. Second, all the electronics in the lens will be opaque and could occlude your regular vision. Let's suppose you can move most of it to the outside of the lens (as with coloured contacts now), the HUD part is still going to cover part of your pupil. So it needs to be really tiny and still produce a clear image. Not impossible maybe but very hard.

- Health. Less of a showstopper, but contact lenses need to breathe. Impeding the flow of oxygen to the surface of the eye can lead to corneal neovascularization - the growth of blood vessels over the cornea. So ideally these contact lenses need to be gas permeable as well.
When defining our initial data schema, we forgot to put a unique constraint on user email addresses. There ended up being quite a few duplicates, so before we added the constraint I had to write a query to remove the duplicate users. About 2/3 of our users didn't have an email listed, and my query failed to take that into account, so it wiped out all but one of those users.
Hi there,

I saw this comment and the one on TC as well, though a little bit later than expected.

I'd love the chance to chat with you further, since it seems you have many unanswered questions about our process, our mission, our research backgrounds, and our process of transparency. We are working hard to improve the way we message these things, so a chance to answer them for you would doubtless be helpful for future inquiries.

Feel free to drop me an email at denny@microryza.com! I would really love to learn more about what you are thinking.
As said it's not the same thing.

MD here. The headline on your webpage: "For serious medical conditions, you need direct access to the world’s best researchers." [my emphasis added]

Pardon my skepticism, but that sentence and the rest of your not-functioning-very-well website smell of nothing more than an attempt to ripoff very vulnerable people, and other marketing bullshit.

But do please prove me wrong - kindly link to the world-class research your docs and researchers have done thus far.
And this would be my response, should I become an android-investing capitalist: Take my profits, create a community, and invite people a family unit at a time to live there (as profits increase, invite more people); you get a place to live, food to eat, and all you have to do is learn to fix the androids when they break. We can all be leisurely, except that once-in-awhile when an android needs a-fixin'.

>That's a large part of the reason I like semi-enforced distributions in curve-oriented review systems.

I'm still at the point where I tend to see the disadvantages of this approach. It seems to me that, in terms of performance management, that the important pieces are the regular one on ones and an honest effort to work equally with people who are high/normal/low performers to improve. A forced distribution seems to work against that because it puts people in the position of defending themselves rather than being open to a discussion. However, that's my view from a bit further down the food chain from your own experience (as a first level lead for teams between 21 and 37 developers). I also agree with InclinedPlane that ultimately it's about intrinsic motivation and being connected to work that interests you. If you can create that kind of work environment you'll get developers who are engaged and want to work hard because it's something that interests them.
It's probably worth testing, but as hackers and web users we all can't stand websites that don't list prices.
Have they given any indication of what stage in development they are in? Do we know this thing works yet? I couldn't find any mention on their site.
It's nice to see more tool support for dart, hopefully lowering the bar of entry for developers.
My bet is this is a short lived trend, like other buying mechanism; coughgroupon.
Doesn't sound like open sourcing is relavent to your product. Focus on the minimal viable product, getting users and growing that revenue stream first. You can always open source later.
Try getting DOCSIS 3.0 (50Mbps down/5Mbps up) if it's available in your area. That's what I have both at work and at home, in NYC, and it's great. The service rarely ever has outages, and speed is very good. I am using Time Warner as well.
Ah! Yes, very soon, you may be banned for overposting. Then you will only be allowed to submit two or three posts a day! That is what happened to me.
Yup, there are all sorts of interesting problems in solving the back end problems of organizing our research.
Your example doesn't fit the parameters discussed.
Maru (a Lisp) looks awesome! However, unoptimized C runs at about 25% the speed of aggressively-optimized C.

The current version of Maru seems to be about 9000 lines of code (almost half the entire complexity budget for STEPS!) I think this reinforces army's original point, "Sure, you can define a lisp interpreter in very few lines of code. But to build a decent standard library and optimizing compiler/JIT, that is where the LOCs rack up."

Well, standard consultation does not cost $5000. If I have $5000 to spend, why should I use this website as opposed to directly finding another expert (with real MD degree and hand-on experience) and get their second opinion? I'm not sure of equivalent hourly rate of doctors but even at $500 per hour, I should be able to get a real specialist to study my reports in-depth and take their couple of hours of consulting time for a fraction of the cost. Again website needs to make explicit how much it would cost, who would do the work and what are their credentials. Lot of statistics such as 50% of second opinions contradicts looks very bogus. Is it from a reliable source?
I'd say rel=nofollow ALL user generated content.. but hey, that's just me.
Our consultant network includes Nobel laureates, heads of biology departments, famous professors, and as top-rate people as one can find. They aren't on the first version of the site because a) they're not full-time employees - being very busy, they usually only have a few hours a week - and b), before you ask someone to be on a website, you first have to show them the site, and the site's only been up for about twelve hours because it's launch day. We're currently compiling our business, scientific and medical advisory boards, and will have them up over the next few weeks.

Also, why the rudeness? In terms of the disagreement hierarchy (http://www.paulgraham.com/disagree.html), you're using DH1 through DH3 - attacking credentials and tone rather than facts.

WordPress: What is an optimal CMS experience?
> HN is for brutally honest feedback

HN is for civil discussion:

" The most important principle on HN, though, is to make thoughtful comments. Thoughtful in both senses: both civil and substantial."

http://ycombinator.com/newswelcome.html
If you have a relatively small site.. curating content isn't too bad... limiting the tail of articles so that comments can only be added for X days helps with that. Only allowing logged in users to comment (and making login easy via oauth sites like facebook/twitter/g+ etc) I kind of like Disqus, but would rather have something more home-grown.
What keeps the valuable, skilled, and productive employees from switching to a more accommodating firm while the useless workers who couldn't find employment elsewhere scramble to hang on? Seems like this could easily backfire.
Those are pretty much RPC (remote procedure call), which Kay names as the opposite of message passing. My take on what Kay is saying is that he is in favor of something much more like "service oriented architecture" -- but certainly without all the buttloads of cruft that have come to be associated with that phrase.
Last week, we talked about several specific problems with WordPress. I know I said this week we were going to look at some solutions. But in thinking about the problems mentioned, I realized that it was more important to first go over some key user experience (UX) principles before discussing specific solutions.

So this week we will look at what an optimal CMS user experience should look like. We’ll outline the groundwork needed to create a really good editing experience in WordPress, and any other CMS.

I'd attribute it to your custom software. Break phpBB and you can infect thousands of sites. Break your custom software you get to infect 1 site.

I ran a forum using SimpleMachines. Turned on all the spam fighting stuff. Didn't matter. Bots or Mechanical Turks made 10-30 new accounts a day. I tried moderating the accounts but who wants to spend time every day to delete the fefRFGR34@foobar.com account.

I gave up and shut it down.
I wouldn't.

You might be able to make an argument for the tech workforce reflecting the demographics of people with CS/engineering degrees, but not of the population as a whole.

Leaving eye color aside it's a simple fact that members of some groups are much more likely to go to college than others. Black males, for example, are more likely to go to jail than college. Of those who do go to college relatively few study computer science. Are we supposed to be surprised that there are few black coders? Is my company racist because I don't hire non-existent black computer science graduates? Give me a break. There wasn't a single black person in my CS program in college but there were several East Asians and at least one Indian.

Who are these people who think that companies are racist against blacks and Mexicans but not Indians or Chinese? Ever work in tech? Ever notice how many Indians there are? That's some mighty selective racism.
Anyone have a mirror? Seems to be down for me.
My own standard is this:

foreach ($array as & $ref) {
// Do something with $ref
} unset ($ref);

i.e. put the `unset()` call on the same line as the closing brace, forever "welding" it to that block.
Interesting take on the matter.

I think it's a generally accepted view that pirating does create more buzz, or at least free available content will get more buzz, than locked down stuff, if it's of the same or better quality as the paid stuff.

> Also, why the rudeness? In terms of the disagreement hierarchy (http://www.paulgraham.com/disagree.html), you're using DH1 through DH3 - attacking credentials and tone rather than facts.

I think you've got things turned around a bit here. He's not using claims of authority to spuriously attack an argument that you're making. You are the one asserting authority, and he's asking for proof. Since you are basing some of your credibility on authority, it seems like a reasonable request.
About the N9, there is almost no relationship between Meego+Maemo hybrid on N9 and Tizen, except for use of the Linux kernel, despite some claims otherwise. APIs and most of the libraries appear to be very different. For example, Qt was the primary native API the N9 but is not supported in the official SDK for Tizen. Tizen is instead supporting Bada's native APIs.

Further, the critically acclaimed UI on the N9 was a proprietary solution developed by Nokia and Tizen has a different user interface.

I think you are right on this point: they need to figure out the strategy and direction of the company, and then blast it out everywhere (isn't this the CEO's job)? Define the vision, communicate it, then arrange your resources to aggressively pursue it.

I see this all the time and it makes no sense. Mayer has not eliminated maternity leave. She eliminated working from home. They are not the same thing.

You cannot work full time from home AND take care of a newborn baby. Anyone who has been at home with a newborn knows this. Working from home is about flexibility and focus, not cheaping out on child care. If you work from home, you still need someone to watch your kid(s). If you are watching your kids, you're not working to the same extent you would in the office.

So yeah, Marissa created a situation so that she could come back to work way earlier than most new moms do. I bet the board of Yahoo prefers that to a CEO who takes her federally-mandated 3 months of family leave.

Why would this be a strange concept?

Every network service offered by a company -- mailserver, Samba, proprietary web applications for internal use, whatever -- needs to be locked down pretty hard if it directly faces the Internet. It takes time and engineering talent to make sure everything's configured securely. If you don't believe this, take a look at the length and complexity of the top Google result for the terms mailserver howto [1].

Servers still should be secured if they're accessible on the VPN, but limiting access to employees vastly reduces the likelihood that an insecurely configured server will be hacked. (Compared to an identically configured server with an unfiltered Internet connection, that is.) Not having servers connected directly to the Internet also provides another level of protection against zero-day exploits. And if something does happen, the VPN's login credentials can point you in the direction of who's responsible [2].

[1] http://flurdy.com/docs/postfix/

[2] Bad guys can still get on your VPN if they compromise someone's credentials with malware. To mitigate this, many companies that use VPN's either require client machines to run regular virus scans and keep their OS up-to-date, and/or only issue login credentials for company-issued machines.
Ask HN: Having trouble finding 2 past submissions; can anyone help?
1. There was a post in the last 1-3 months for a site that offered photographs of (mostly) Apple devices out in the real world. I vaguely remember a photograph of a macbook on a picnic table. They were offering real photographs/settings for you to lay a screenshot of your website into.
2. There was a post in the past couple weeks for a tool that (as of it's posting) tracked python package and NPM releases. You pay monthly to get notifications about releases of various packages you're interested in. They promised support for Ruby gems in the near future on their blog.

Thanks.
The problem is that the retaining company doesn't receive black marks for hiring bad recruiters because the companies are anonymous until the candidate shows strong interest (and this were happy to receive the call.)

I can think of two healthier payout structures. One is for the recruiting company to pay regardless of results and better instruct the recruiter what to do and not do (this would be followed more closely since there would be little incentive to spam.) The other is to retain the firm and pay an earnout for every candidate hired during that period regardless of source, with the understanding that the recruiter must identify the company that is hiring.
I don't understand why you would ever refer someone to a job through a cold-calling recruiter. If you know someone good who's looking for a job, just help them find a job directly.

"Ignore advanced web developers complaining about ‘not another Bootstrap website’" I agree. It's your customers that matter. And unless you're building a product for advanced web developers, pleasing them should be no matter to you.

I've shown Bootstrap sites to non-developers and the response is usually that the sites look nice. Never has it been "ug. boostrap?".

>I don't get the ire against HFT. The only ones who should be worried about HFT besides regulators are the human traders who are going to be put out of work by HFT shops.

I'm not convinced that HFT is anything particularly insidious, but the fig leaf of providing liquidity is pure rubbish and it seems like the sort of activity that shouldn't be rewarded with billions in profits. It reminds me of the scam from Office Space. Take a fraction of a penny from a large number of people and nobody really cares, but that doesn't mean you deserve the money. And it's causing an enormous amount of resources and brain power to go into beating the runner up by a fraction of a millisecond that could be going to something more productive.
You made an account 18 days ago and you're posting 10-15 posts a day? Maybe you should try to get involved in the community a bit.

Sorry for the total sidetrack but I laughed out loud at this title.

Maybe its just my New England sensibilities (read: frugality) talking, but I sometimes refer to Silicon Valley as "the land where money is make-believe". I'm referring to the (perceived) bubble of course, but also my (perceived) view of the conspicuous consumption that seems much more pronounced over there than around here, perhaps as a result of VC money.

I swear walking around some places I didn't see a car that was made between the years 1960 to 2005. They all looked either vintage or brand new.

Not that it's a bad thing, I'm sure people have a great time and get things done, etc, but my mind translates the title as "In a bid for credibility, largest make-believe currency exchange moves to the land where money is make-believe".

I mean is there a place in the U.S. where the cultural perception is that people take large sums of money less seriously?

Our rendition and torture programs are not governed by the rule of law and are known to take into custody many innocent people. The decision to carry on with these programs even though they are quite flawed is essentially the decision to carry out collateral damage on civilians... on purpose.

Also, don't be deceived and think that "smart" bombs and missles are smart enough to avoid lots of civilian casualties. They may be better than the previous technology was, but they are far from perfect, and considering that they are used outside of an actual war (targeted strikes in mostly civilian areas) there is definitely the deliberate tradeoff being made to commit some very horrible atrocities in the hope that the actual (though still extralegal) target is the one who gets killed.

And, when you consider the horrible regimes we support and fund (yet also turn on when their atrocities are exposed) it becomes clear that the US Government is the largest sponsor of human suffering in the world.

This is too bad, and it's escalated under Obama. Our militarism is out of control to the point where a massive propaganda effort must be used to keep the public supporting it. Smart bombs are actually propaganda bombs, b/c the footage can occasionally be used as part of the "good guy" narrative that is fed to the public.

For some reason "retirement" comes to mind as having a disadvantage when it comes to women who chose to start a family (compared to men who chose to start a family) but I'm young and planning a offbeat retirement plan for myself, so I don't know much on common retirement to elaborate on it.
