(disclaimer, I work at Scopely) I don't quite understand what you mean by saying that it's an "office for sales people". Agreed, it's a bit crowded! I think we doubled (or more?) our team's size since we moved into this space. But other than that, the type of office suites me and most developers quite well. We are working on acquiring more office space and making dedicated "quite rooms" for people to work in with less distraction.

It's been at the back my of mind for years but I haven't found the courage to do it. The reason may sound silly: I feel extremely squeamish with anything that involves contact with eyes. It's the same reason I've stayed away from contact lenses and keep wearing stupid glasses instead. If there was a way to fix my eyes without me or anyone else having to come in contact with them (at least when I am conscious), I'd do it in a heartbeat. Anyone else with the same hang-up?
That's not really the point, which is that terrorist tactics were being used in the region long before the United States existed.
Get one eye done, then the other a few months later (2nd only if you are happy with results).

If you get both done at once, you have no objective way to independently compare whether the results are better than what you already have....

My doctor was pushing me to get both done at once, but I wanted to have a control to compare against, and boy am I glad I did.

Both my eyes were about -6, but I only had my right eye done (left eye not). It is useful having one eye that doesn't need contacts. But it is also useful having one -6 eye because it makes close-up work easy (I can't use the right Lasik'ed eye for fine detailed work - it can't focus on anything closer than 30cm - like long sighted but actually isn't).

With a contact in my left eye, and the Lasiked right eye, the left eye has much better clarity even in day time. The results on the right eye were normal (this situation isn't because things were stuffed up).

The halo effect is due to uneveness/dimples/ripples created, so can never be corrected by lenses.

Anyone that has both eyes done at one time cannot make an objective comparison of advantages/disadvantages.
Watch out, this affects small rails applications with few dynos as well.

If you hit the wall with one dyno and add another one, you won't get twice the throughput even though you pay twice the price.

I've always had suspicions about this on some smaller apps but never really looked into it. You can configure New Relic to measure round-trip response times on the client side. At peak loads those would be unreasonably high. Much higher than can be explained by huge latencies even.
Blade Runner kills his GF
What is happening in North Korea can only be summed up as epic fail at human rights and people's right to free from an oppressive regime.

Maybe I don't quite understand how mass psychology works, but I know that the population of the country is 24 million people and that the current system probably doesn't benefit 99.9% of that population (the other 0.1% being the regime members, for whom the whole thing works out just fine). Sorry for pulling the numbers out of my ass, but I am trying to convey an idea here.

If that's the currently the case, then why wouldn't those 99.9% rise up and overthrow the regime that oppresses them? Even the soldiers are most likely normal people who have been conscripted at some point, why would they kill their own neighbors, friends and family members in the case of such an uprising? The people of North Korea have EVERY reason on this planet to overthrow their "government", what's preventing them from doing so?

Like I said, I may be totally misunderstanding how mass psychology works in dictatorships, but this kind of thing seems pretty logical to me, even a no-brainer. Is it the lack of critical thinking? Critical mass? Inability to build up that critical mass? If so, why? Do people there really rat on their neighbors and family members like we often hear?

If I were a more dismissive person I would just say "They're just getting what they're asking for", but I really want to understand how this works better, so someone please enlighten me.
I have a permanent side effect from LASIK which is dry eyes. it's supposed not to last more than a couple of weeks, but it's essentially permanent in my case.
That's one way of putting it.

Another, more correct way, would be to state North Korea invaded South Korea and the US (and its allies) stepped in to stop them. They did this not to "free North Korea" but to prevent "communism" from overrunning one of its allies.

(They were also so succesful at it they pushed back North Korea almost all the way up to the Chinese border, which got China very nervous, leading to them getting involved as well).
Two issues: One, in a matter of dispute, he is claiming his own logs as proof -- which is nonsense. Two, even if the logs are legitimate, the error could have been somewhere between the computer and the user (e.g., the user might have been getting wrong information).

In either case, Tesla is being very unprofessional. Very petty, too. Think about Musk: he created PayPal, where he was a total scumbag. Why would it be different here?
Well if you want to start with the previous product, the inPulse, they have an SDK here:

That is why when conducting a review and not just a blog post , you should have a protocol - what were you testing, how, why.

After all - see how detailed the testing methodology for some hardware sites is. For a world class media like the times it is inexcusable. So it is very sloppy to have times making reviews of expensive products that are worse than these of 300$ video card.

I pushed the car to the limits is a viable test, just notice it.
You're definitely not alone. I cannot stand anything getting near my eyes, so there is no chance I could ever wear contact lenses.

I don't mind my glasses, mainly because I'm very short-sighted and really need them if I'm driving or walking around outside, but if I had the guts I'd probably get the surgery. The thought of having lasers shone into my eyes while I'm still conscious is enough to make my stomach turn.
"simply smash one group of soldiers to another" Wow, massive simplification of a highly effective discipline based strategy (nicked off the Romans).
You've made those tactics succeed. It is your fault that sites keep using them.
It's interesting to compare the state of charge and range remaining graphs around this point. Remember the x-axis is miles, not time. The car does not appear to have lost much charge overnight, but with a cold battery, it's discharging much faster just after he starts driving again. Thus the range remaining is pretty low, even though the battery is still charged. As soon as the battery warms up, the discharge rate becomes what it was the day before, even before he's got to the Norwich recharge station. For some reason though, the range remaining graph doesn't increase after the battery warms up, when you would think it should.

From looking at these graphs, it doesn't look to me that there's a problem with losing charge, but there may be a problem with how the state of charge is reported as range.

> or Mac OS X should tailor its windowing system to Photoshop CS4

I'm taking this example out specifically, because it illustrates my point quite nicely.

If there were a sizeable community of people who only wanted to use a computer for Photoshop, and tailoring the windowing system to them made it a significant usability improvement for those people, then it would be a completely imaginable situation that upon first opening your brand new Mac, it'd ask you whether you're one of those Photoshop people and want the special windowing system setup.

Well, ok, haha Apple and customizing anything for anyone, ever. But many other vendors might make such a choice.

The apparent stubborn refusal of many PaaS services, including Heroku and yours, to particularly tailor to a very common configuration of Rails sounds like a hole in the market, to me. As a customer, I don't care whether this is "incorrect" because Rails does not conform to some yet-to-be-defined standard or simply because the PaaS doesn't have their shit together. The customer experience is the same: I'm running a blog tutorial app, and the performance sucks.
Thing is though, it says that a Dyno is a Ubuntu virtual machine. In what sort of horrendous configuration can an ENTIRE VM serve only a SINGLE REQUEST AT A TIME?!

That is utter madness, and the validity of the argument depends on whether it's the Heroku or this dude's fault that the VM is serving only a single request at a time (and it taking >1sec to handle a request).
Like the OP, I'm assuming many of us, have a great deal of respect for his intellect and integrity, but honestly, I can't help feeling a bit let down by the way Mr Musk has handled the situation.

Musk opens the rebuttal with: "We are upset by this article because it does not factually represent Tesla technology, which is designed and tested to operate well in both hot and cold climates."

It certainly feels somewhat disingenuous to mention nothing, of what arguably should be, the central discussion point:
The Model S (more specifically the car's Li-Ion battery pack) performs unusually poorly in frigid conditions.

While as a nerdier group we tend to love data and generally have a higher faith in empirical methods, in this instance, it does appear more like a data deluge. As a result, this ends up detracting focus and deflecting any valid criticism of the car.

Although I've been following TM for years now, the battery pack temperature issue was still a surprise to me. More importantly, Tesla owners are finding this out the hard way too. [1][2]

Did the NYT reporter add a little journalistic embellish to the story? Probably. Is the review a complete work of fiction as Musk judged it? Unlikely, and what is more probable is that Musk has simply overreacted and has taken it personally. Indeed he is still human after all.

I don't need to stop whatever I'm doing to think.
To stay with your Ratatouille analogy, how does YC know that "someone (anyone) can cook"? Either they eat something that you have cooked, or they look at your past achievements to see if you can cook (chef at a Michelin star restaurant maybe?). Barring these two, YC doesn't know that you can cook.

If you build a site which gets 10 million visitors daily, YC will know that you can "cook", and won't care about what your background is.

Slightly weird coincidence.
Doesn't know even the basics of thermodynamics or can't apply it to his subject.

Oh really? You probably also think that cold water freezes faster than hot. Taking the thimbleful of knowledge that you have and making snap judgements based on it will often mislead you.

In the case of the cars, without looking it up it is not obvious to me which is worse - the energy loss in starting and stopping at low speeds, or the quadratically scaling energy loss from wind resistance at high speeds. Certainly if you go fast enough you'll find that your driving range drops substantially - this is why the old 55 mph limit was passed during the oil crisis.

If I am not certain without looking it up, then I can't fault someone else for not knowing it either.

About the water, if you have equal amounts of hot and cold water in wooden buckets and put them out in the snow, the hot water can easily freeze faster. Several possible factors are known, but their relative importance is unclear. See http://math.ucr.edu/home/baez/physics/General/hot_water.html for a detailed discussion.

Actually the laser itself is the least of my stomach-turning thoughts. It's things like this from TFA: "a thin wire kind of thing was slightly poked into the side of my eye to see how many tears I would shed in a certain period" and "an instrument was physically pressed against eye, which vibrated in and out slightly". No way Jose.
I don't think anyone is claiming that, just that it is a good introduction to the principles.
You're assuming that the change was actually made. Until we hear definitively from Heroku, the only evidence is an (admittedly, well documented) blog post.

Erhm. What?

I had both eyes done and I can surely compare before/after; I don't need contacts anymore.

I don't know how long you waited before you had your other eye done, but it takes ~1 year before the eye is fully funcitonal and the brain re-callibrated.
Hey Dmitri, a couple of questions...

Will you be reducing the involvement of sponsors now you're raising £3k per event?

What are the additional events and projects now in the pipeline as a result of the extra funds?

Having just got back from San Francisco and seeing a lot of the pay-it-forward culture in action, I'm glad there is a fee at it means that we're able to contribute to something that can help build something larger and be part of a difference in the London startup culture. So I'm really keen to hear about how those funds are now going to be invested to make that change happen.

Also, while it's okay to have a somewhat complexe form to fill when making a request, it's really sad that it's as much work to share a paper, it should be very easy, in particular when clicking "I have this, send it", the form should have only one field: the file upload, or at least have the other prefilled with the request's values.

> Previously it seems that only one request could be handled by the dyno so requests had to queue on the dynamic routing layer but with multiple request support with unicorn or whatever, wouldn't it be more efficient to dump all the requests to dynos?

It would be if all requests were equal. If all your requests always take 100ms, spreading them equally would work fine.

But consider if one of them takes longer. Doesn't have to be much, but the effect will be much more severe if you e.g. have a request that grinds the disk for a few seconds.

Even if each dyno can handle more than one requests, since those requests share resources, if some of them slows down due to some long running request, response times for the other requests are likely to increase, and as response times increase, it's queue is likely to increase further, and it gets more likely to pile up more long running requests.

> Followup question, also how would intelligent routing work if it just previously checked to see if which dyno had no requests? That seems like an easy thing to do, now you would have to check CPU/IO whatever and route based on load. Not specifically targeted at you but to everyone reading the thread.

There is no perfect answer. Just routing by least connections is one option. it will hurt some queries that will end up being piled up on servers processing a heavy request in high load situations, but pretty soon any heavily loaded servers will have enough connections all the time that most new requests will go to lighter loaded servers.

Adding "buckets" of servers for different types of requests is one option to improve it, if you can easily tell by url which requests will be slow.

I'm too risk averse for eye surgery (read the other comments, it's not perfect for everyone, doesn't always last, and you only have one pair of eyes to play with). I used to wear glasses, because I found contact lenses to be too much hassle.

About three years ago I swapped to "silicone hydrogel" continuous wear contact lenses. After getting used to them, I can leave them in for a month at a time, and then throw them away (no cleaning!). I forget I'm wearing them, and wake up being able to see. If you have severe short-sightedness (I'm -8) having contacts makes everything bigger than with glasses, it's much better. I recommend giving it a go; opticians often fall over themselves to give you a free trial.

Edit: the precise lens type I'm using is Comfilcon A (Biofinity, CooperVision), which wikipedia describes as "3rd generation" silicon hydrogel. There are other types, and apparently different people get on with different ones.
I did FS-LASIK exactly 1 year ago. I didn't have very bad sight at the time only had to use glasses/contacts when driving a car but I felt this was just a hassle.

My doctor told me that it would take about 1 year before my brain calibrated correctly, these "spikes" (dunno what to call it) around for instance car lights goes away after that time because the brain needs to "get use to it".

According to my doctor my result was better than expected, I've got as perfect sight as possible after the operation. I did however spend a couple of days in bed even thought I was told that I could work within the next couple of days (I wanted to be on the safe side though).

People have asked me if I would do it again and I sure would.
Anecdotes aren't worth much. What matters is statistics. What fraction of those who have corrective surgery regret it? The answer: less than 1 in 20. Most of that fraction includes those who are unhealthy: mainly people with high blood pressure. Those who are in risk groups shouldn't go for it. Everyone else should. The FDA, an extremely risk-averse organization, advocates laser eye surgery [1]. In almost all circumstances, those who undergo surgery vouch for it.

I had epi-LASEK in both eyes, spaced apart by 10 days. Even though healing times for my surgery are measured in weeks, I could certainly tell the difference between my corrected eye and my uncorrected eye. LASIK is much more pronounced, since one's vision improves within days instead of weeks.

Yes, yes, but isn't it awfully interesting how with all of Mr. Broder's complaints about the car, he completely forgot to mention just how hard it was to find the Supercharger station? Doesn't that seem like a relevant detail in an article ostensibly reviewing the Supercharger network?

I'm just so upset that I can't help wringing my hands. Just think of all those uninformed citizens. Those poor souls buying this fancy car with the wool over their eyes. So naive: thinking they can just drive right up to a Supercharger station whenever they want with nary a thought. Who is going to tell them that they must not only drive to the station, but commit to a parking lot odyssey? Think of all the electrons that will be burned whilst the good people of this country waste their time searching for a Supercharger! Who? Who, I say, will bring this message to the masses, if not John Broder? And he has failed! For this, I demand the Times investigate his journalistic malpractice at once!

Seriously, though, at what point are allowed to invoke Occam's Razor and admit that maybe, just maybe, Mr. Broder may not have been giving the car a fair shake?

Like what? Numbers and studies? Khan Academy said that they have very promising results in which students perform significantly better on standardized tests.

That being said, I already wrote in my post how we can improve efficiency and effectiveness by leveraging computers for all they're worth. I think this is sufficient to show how dated the teaching is done in schools, if not exactly proves how inefficient our school teach. I think it's quite obvious that it's better to watch a recorded lecture than to see the teacher perform the same lecture years after year.

I ask because my girlfriend is a teacher, and teaching is a lot harder than most people seem to believe.

All I am advocating is giving the teachers and students better tools based on cognitive science that we discovered a long time ago. Making sure students get the practice they need on summer vacations and scheduling practice problems to reduce unnecessary studying isn't rocket science.
