Ask HN: Have you had laser eye surgery? What was your experience?
Hi,

I am a long term HN member writing under an anonymous account as this is a somewhat personal issue for me.

I have been short-sighted (myopia of about -5.00 in both eyes) all my life, and generally wear both contact lenses and glasses. I find contact lenses really irritate my eyes when programming (dry eyes due to less blinking when on computer) and am fed up of issues with glasses (steaming, cleaning, etc) and recently have been considering laser eye surgery.

I live in the UK, and have booked consultations at the 3 main providers here - UltraLase, Optimax, Optical Express. I'll write my assessment of them each later once I go for my consultation with the last provider at the end of the month, but so far have concluded that one has to really research the area to avoid much of the nonsense that they tell patients especially with regard to equipment and surgeons used and why e.g. Ultralase charge £4700 for lasik+intralse+wavefront and say they use new Bausch & Lomb lasers that has higher resolution (dpi) and better surgeons (but ironically most of them are ex-Optimax surgeons) but Optimax charge £2395 for a similar lasik+intralase+wavefront procedure but say they use Nidek lasers as gives better results (even though it is older generation device) and they are cheaper as they already bought their machines and premises and have less ongoing overheads.

Anyway, I was wondering if any other HN members have had laser eye surgey (or thought about it and why you did not do it), what prodcedure you took (e.g. Lasek, Lasik, with Wavefront and/or Intralase), what your experience was like, what equipment was used (e.g. Visx, Nidek, Alegretto), and whether you researched this and what your thoughts are about various equipment-factors in the final result, and most importantly your surgeon and final result.

Thank you!
The useless apps get more downloads but I'll bet they're gone as fast as they're downloaded, the churn on that stuff must be enormous. Whereas if an app has real utility I think it will hang around a lot longer.

His marketing is great, I'm sure if that gets applied to a real blockbuster he'll clean up, and make quite a bit more than a few grand. Of course making a serious app with real utility is going to be a lot more work so in the end it might work out to these being still 'easier money'.

As for him living in Poland and not being able to put his apps in the 'paid' section, that's a really nasty thing and should be remedied asap. The playing field is definitely not level in this respect.
Pump-Powered Antennas Could Replace Metal with Fountains of Saltwater
To curb calories, he avoided meat, whole grains and fruits.

Hmm, confounding. There's a lot of crazy stuff in meat, stuff that might well have something to do with obesity rates rising.

There are many studies that show that the vegetarian diet is the most healthy. His results may have less to do with Twinkies than with the meat he avoided.

Edit: Not sure why I'm getting down voted to oblivion? I eat meat... I have no agenda here, just pointing out a deficiency in the article's reasoning.
Something of note: The antenna is near your mouth, not your ear.
Yes, it gets better. Much better.

One big difference you'll encounter after working for just a bit in the commercial world is the amazing, energizing power of a (fat, steady) paycheck. Which somehow really, really helps us bear down and get that (let's face it) nasty slog of niggly, piggly, nose-in-the-mud gruntwork that is most commercial development.

You'll also encounter the opposite, from time to time, i.e. employers who just don't grasp the incredibly demotivating effects of the skimpy, late, or consistently unreliable paycheck (and their sidekicks: poor physical working conditions, bumbling junior management, conflicting and/or basically impossible goalposts, and my favorite, utterly made-up deadlines with no connection to business or technical reality).

But fear not: once you've had a steady enough taste of the former type of environment, you'll be able to recognize (and pivot yourself out of) the negative/unstable environments, before too much damage has been done to your savings and/or your resume.
I think a key point of arbitrage is that you do both of the transactions (the buying and the selling) at the same time.

This insulates the person doing the arbitrage from losing money because one or both of the markets changed (it is 'theoretically risk free').

So they would be theoretically be trading page impressions as they occur, to the highest bidder. Compare this to AdWords, which offers 'some amount of Cents' per impression.

You sell your adspace to opera, opera sells that AdSpace to someone else, dynamically based on market prices. (They could even sell it Google or whoever). Its like an ad stock market.

At least, that is my (very) speculative understanding.

edit: The key point is that they control the cache, so if you sell them ads and your page goes through the cache, they can insert it (whoever's ad it is) quickly. Otherwise it would be an extra level of indirection loading the ad.
Assuming we have a corona ejection, how long a warning would we get?
I would pay $20 to have this set up for two weeks for me. That would give you $6 you could keep for yourself. I'm sure I'm not the only one. Business here possibly?
Indeed. Blocking JS and CSS from all robots will also cause your site to render poorly in most web archives, like the Internet Archive Wayback Machine.
Funny you mention that; the original syntax was actually based on ECMAScript, so the syntactic similarities with ActionScript are not accidental.
i'd pay extra for that.
Yea Signal vs Noise is also on my must-read list.

forgot to mention :)
This is said a bit in humor, and might be seen as a bit of a jump in context, but is the effect the article discusses a reason we have to have so many friggin' meetings?

Your privacy is important

Even when Turbo is enabled, encrypted traffic does not go through our compression servers. This means that when you are on a SSL site, we bypass these traffic and let you communicate with the SSL site directly. Opera generates statistics of the usage of Opera Turbo, but these are aggregated numbers and no information can be linked to a single user. Opera does not store any users’ private information.
We do have a "non-binding" estimate, but they can't turn the wheels in their large organization to get payment for more than the high end of our non-binding estimate. And no one takes us seriously if we say "probably 10 to 12 hours, but this kind of work occasionally has problems that will balloon the costs to 20 hours."
It's a pain in the ass because no-one is on your side.

If you could find a recruiter who got 20% of your signing bonus, it wouldn't be so bad.
Thanks, that's a helpful response. In response to your second paragraph, I'm targeting web professionals (i.e., the group of people most likely to recognize and look down on it), hence my worry.

If he has professional bouncers, and zero-tolerance against drunks, pre-drinking isn't going to be that big an issue and as for after parties, that would be the parents problem (shouldn't they be picking up their kid?).
I think we already have a couple of satellites deployed. (Source is a documentary I watched last month)
Great idea. Seems obvious in hindsight, but I can't recall ever seeing it before.

From a feature perspective I'd like to see more reviews on parts, price to performance indications, and part hierarchies.

For example, I know what an i7 is - but I don't know what the difference is between an i7 870 and an i7 875k. Once I select an i7 I'd like to see descriptions, a breakdown of reviews, and prices to benchmark performance.

From a business perspective you should start to come up with a business model. This is a really cool site but it's also a lot of work to do right. Do any of these sites have affiliates? If not, you may be able to get merchants or hardware manufacturers to pay for paid messages, but that seems doubtful. So failing that it's possible someone like newegg would want to buy this tool from you, but they'd probably just copy you instead.

Other ways to make money: Show people how much money you saved them via comparing merchants and ask for a donation. Sell premium features to people who buy in batches for companies or local shops. Offer to assemble PCs for people. Maybe you can make some money selling MS software licenses to people.
Alright, I know you said you are not responding further, but you are misinterpreting what I am saying. At no point have I been unwilling to acknowledge that Martin committed an intentional act that was wrong. I am not saying that Zed is at least as wrong, not even close. The most wrong person in the entire exchange is Martin. I've clearly failed to communicate this to you and I apologize.

I'm just trying to say that when people make mistakes they should be corrected, but correcting them politely is more effective. I think this is especially true when the person who made the mistake looks up to you.

You are free to disagree with that, but please stop putting words in my mouth.

Edit: If I'm not mistaken, you have just said that Zed's response was "mildly harsh". It looks like we agree with each other. I think Martin committed copyright infringement and that Zed's response was mildly harsh (I think I initially used the word "rude").
Context: There's a big pseudoscience movement very similar to antivax that's essentially trying to get cell phones banned — the precise reason varies depending on the opponent, but a common one is that cell phones use microwaves and that's the same thing we use to cook popcorn. The range of harm cell phones supposedly cause is amazingly wide and pretty fuzzy, including autism, cancer, fatigue, insomnia, "brain farts," confusion, a burning sensation on the skin, anxiety and death of plants and animals.
Un-fucking-likely, Bruce. You mean after JetBlue, Virgin and all the rest tens spent millions of dollars putting WiFi on their airplanes, TSA is just going to undo that with a security directive?

Naah. It may or may not make sense from a sense from a security standpoint, but I can promise you that it will not happen. Not as long as big business is still running the American government.
Thanks for the feedback! I agree - the individual parts do need more information, and that's something I plan on augmenting. Regarding compatibility - I'm slowly getting to the point where I can guarantee compatibility. There's a lot of combinations and data points to fill in. It gets a little complicated with things like CPU/Motherboard compatibility, which can vary depending on bios revision. I've been working on back-filling that data both with web scraping (have to be careful - even some manufacturer spec pages have errors) and by hand where necessary. In time though I intend on filling in the gaps there.
So it's not a big deal that he's making money doing the opposite of what conventional wisdom (and media) says sells, namely parties with the opportunity for underage drinking and drugs?

Kudos to this kid+father for finding a way to make money doing the right thing.
His premise: That in weight loss, pure calorie counting is what matters most -- not the nutritional value of the food.

This should not be a startling revelation. Mind you we're speaking simply of weight loss, not "healthy eating" or "good nutrition" or any of the other topics that people often mix up with weight loss.

It seems that in Professor Haub's case that the benefit to losing the weight outweighed the negative consequences of eating junk food -- at least in the short term.
Sounds like there's a chance you'll be hurt because you've used a template.

How does that compare to the damage / delay suffered because you had to take the time to design the site? Generally, I'll start with a template to get things running quickly, then do a redesign later. Plus, I've found that redesign a great time to re-architect for the pivots I've experienced, so I have a fairly clean layout post-redo.
Wasn't sure if the EMP pulse would be picked up regardless of power state due to induction in wiring or casing.

If you're right about powering electronics down, a early warning system definitely is a no-brainer.
Point 4 is worth expanding on! Maybe a premium feature can be price monitoring. Premium members get to see price history charts and they can get price alerts.
Excellent idea. I'm looking at the cpu tab now -- will probably apply to all tabs; how about a general "value" gauge that's the average of all values (for non-star data such as speed, cores and price, scaled to the full data set's minimum and maximum -- inverted for price, so high price = low score)?

edit: The video card tab is very lacking in attributes. I absolutely need to know how many VGA, DVI and HDMI outputs a card has. (Also, adding the same to the mobo tab would be useful.)
"My concern is that we are building all of this on top of HTTP, which wasn't really meant to be used this way, and there's bound to be some caveats from that". Can you ( or anybody ) expand on this ?
I would wager this is almost certainly why his cholesterol dropped and explains many of the effects. This is basically the central premise of the book The China Study, which is what convinced me to go vegetarian myself about a year ago (I dropped 30 lbs without even trying in about three months and now I weigh less than I did in high school).

Still, he's eating a lot of refined sugar, so I'm pretty surprised. Then again, so am I (thanks Halloween!).
Between 18 hours to a few days.

Flares can take as little as 15 minutes (with early warning from satellites in L2).

For high energy x-rays there'd be no early warning through other means than forecasting.
Depends on what you are launching. A weekend project? Just get your work in front of people. Something you spent six months in stealth mode working on? Sure, get it all set up before launch during the development process.
Error on the side of caution and require qualified editors to fill in cases like bios revisions. There are so many parts to pick from, it's okay if you error safe and exclude 10%.

No, you aren't. Unfortunately, I must say. All those years taking Social Psychology courses haven't even made me immune to fascism!

Seriously, though, reading some essential papers in the area is absolutely worthwhile. Replications of Milgram's initial experiments have investigated exactly this issue. Knowing that you're susceptible to manipulation by authority figures doesn't make you any less susceptible.
This would be much more interesting if he spent the money on auction items, instead of "Buy Now" stuff where the value is not much more than the price.

My younger brothers go to these events -- the whole point of these events is the pre-drinking and the post-drinking. And from things I've picked up (gotta love facebook), there may in fact be a bit of drinking inside the parties, too. (Not sure how much or if it is true.)

Also, there is a certain indicator of "coolness" and reputation that comes along with being one of this kid's ticket resellers.

I think it is an amazing idea -- this kid certainly has a lot going for him -- kids want to be his friends, kids want to be him, etc. Definitely somebody to watch.
Actually good news. His code just became a lot more readable, maintainable, and shorter.
I find it interesting that nearly all the authors listed are primarily novelists.

> ... these apps are useful to someone, otherwise, kreci wouldn't be making money from them.

this logic only works out if you approach things myopically.

do you think drug dealers provide a useful commodity? they're certainly making a lot of money.

the apps described take advantage of some neurological disposition to gimmicks / novelty - it's not a given that the world is a better place because of them.
Technically you can use XNA too, and you can make a browser using that. Ofcourse that means you have to toss away all the platforms goods and libraries you have and produce that on your own as well. Not really the sexy option, no.

So not saying it's going to happen, but technically speaking it's not impossible either.
"Shouldn't they be picking up their kid?" -- this statement, while probably spot on -- is anathema to raising children in NYC. The kids that go to these events? Are a-okay to walk home close to midnight. I would bet no parents show up at the end of the party to be picked up like at a school dance in the suburbs. (Ha. Oh childhood.)

The kids who have parents that would pick up their kids? From my experience with my brothers and experience working with NYC kids -- they wouldn't be going to the party anyhow.
Doc here. I'm not surprised that an adult male carrying 33.4% body fat dropped weight on an 1,800 calorie diet. Nor am I surprised that his cholesterol stayed down. If you've every seen a patient on total parenteral nutrition or g-tube feeds, they all move toward a normal BMI and then get scrawny. The switch over to skinny is due to muscle atrophy from disuse. If they survive and return to a normal activity level, they typically regain the muscle mass.

The take-away: don't eat too much.

Quiz:

1) what three food groups did he cut out of his diet?

2) What is the normal range of BMI for an adult male?

3) Fat is transported in the blood in various kinds of packets. HDL and LDL are proteins that label the outsides of certain packets. If HDL goes up during weight loss, where do you think those packets are coming from? Where do you think LDL packets are going to? If Professor Haub's weight equilibrates with his new 2100 calorie diet, what do you expect will happen to his HDL and LDL?

A bunch of engineers at idealab did this back during the bubble. The idea was the saturate Pasadena, CA with $2 bills, particularly as retailers, lacking anywhere to put $2 bills in registers, tended to quickly re-release them.

We tried buying them a thousand at a time from banks. One time a manager came out to talk to us about it and asked what we wanted them for. We explained and his response was, "So we're going to get them all back."
I think it actually varies depending on the type of warning, some being considered more severe than others.

Yes it does. Basically it says that opera intends to strip out ads from the pages it serves and replace them with new ads. Which new ads? Opera will simply auction the space to the highest bidder. Obviously this will only work for ads that go through its servers, but apparently it controls a large proportion of the mobile proxying/caching market.
Sounds nice in theory, not sure whether it will hold up in practice. Note they state explicitly they will NOT perform behavioural advertising.

That really is above and beyond. Aside from the fact that many companies will find you completely unattractive if you have Guard/Reserve on your resume, paying the difference to keep your existing salary while not even at Apple makes it very military-reserve friendly environment. But you'll probably still have to weigh the other working environment factors.

(It's even hard for me to convince my investors that I'll be around in case my Guard unit is deployed.)
The Wordpress default install is horribly slow out of the box. The sad reality is that most blog software is not tuned to serve any reasonable number of pageviews by default.

It's one reason why letting someone manage all that for you makes sense. (Shameless plug) At Weebly we spent a lot of time making sure that our blogging engine is very optimized. We have free users -- they don't pay us any money, we don't place any ads on their site, and they even use their own domain -- hit the front page of Digg/Reddit/HN all the time, and we can easily handle it in stride.

To do this right, you have to be able to change the terms of the auction. Allow bidding for the $1 to start at a penny so it seems like a good deal. Then allow that the highest bidder gets the dollar, but doesn't have to pay... and the second-highest bidder must pay his bid amount, but receives nothing.

You should see dollar bills purchased for hundreds of dollars at least.

As an API, it was rather unknown. Guess what really ticked people off was the redistribution of the complete data.

I'll take a stab at #1. I'd say he missed the "fish, poultry and eggs", "healthy fats/oils" and "whole grains" groups. He was eating from the "use sparingly", "dairy" (from the shake), and "vegetables and fruits". Eggs are often in the types of snacks he was eating, so it's possible you could argue he was also eating from the "fish, poultry and eggs" group.

I'm using the groups as defined in the Healthy Eating Pyramid: http://www.hsph.harvard.edu/nutritionsource/what-should-you-...
Two things:

1. If you could somehow get ratings on quality/reliability of parts from other sites, that would greatly help in picking individual parts.

2. If you could also make it group the parts into a small set of vendors so that you wouldn't have to buy from more than X (user defined int) companies, that would be nice.
