I like eclipse, or at least need its features, but it always feels like a fragile program that needs lots of babysitting. In fact right now I'm on HN because I just cleaned a project to force eclipse to rebuild it because when I tried to run my program I got an AbstractMethodError (which should be impossible when running something you just built).
I use sentry, and it doesn't provide anything really like the timeline feature.
I applaud this effort and it is a step in the right direction for JS app error tracking, but it is a half-measure: we need to get to the point where frontend frameworks track this by default, post back to a common server endpoint, and then that error report is emailed to the dev/admin list

Even assuming you START with random experimentation, you will end up with non-random feedback. And assuming even cursory logical competence, the results of experiments will be useful. Even doctors get better over time with experience and practice.
> "you restrict your domain when you divide by a variable expression"

Why is this a problem?

Whenever you perform an operation that has a restricted domain, you restrict your domain. This may result in an actual "not defined at x=1" result, or simply "the value at x=1 is found through an alternative method" result.

> "0/0 is only undefined when it persists after simplification"

When you're working in the context of limits, it wasn't an actual 0/0 to begin with; it was near-0/near-0, which is perfectly OK to simplify. The limit defines a function that already has a restricted domain -- h->0 means h is not actually zero. The expression naively evaluating to 0/0 simply tells you that you need to do more work to properly evaluate it -- 0/0 is not the actual result.

Note that using the limit to find the derivative gives you a function that you'd like to be continuous in x, but the divide-by-zero is in h. Consider f(x)=x^2. The derivative is

lim h->0 [(x+h)^2 - x^2 ] /h

lim h->0 [ x^2 + 2xh + h^2 - x^2 ] /h

lim h->0 [ 2xh + h^2 ] / h

lim h->0 [2x + h] * h/h

since h does NOT equal zero, we can treat h/h=1, and the limit trivially collapses to 2x. Note that we never had the variable x in the denominator of our fraction; we never placed a restriction on x or suggested anything about a discontinuity relative to x. We only restricted h, which was already restricted by the limit itself.
Missing the condition on the UPDATE statement is a classic. I blame the SQL standard which has most of its syntax backwards. It should be FROM <table> WHERE <conds> UPDATE <variables>.

Anyway I dont think you can prevent screwups in general. The only thing you can do is have systems in place which mitigate the consequences of screwups. Like unit tests and backups.

> book on mathematics that demonstrates the "beauty" of it

I'd say that you're asking wrong question. Yes, there're quite a few books intended to demonstrate the very thing you're asking for: beauty of mathematics. You are even likely to find some showcases interesting, might be somewhat beautiful. But essentially it won't be the same "beauty" that mathematicians see. It will be more like a thousand more-or-less scientific examples of how number φ appears in different places in our life, which isn't the essence of it obviously.

So if you're scared by "summation" symbol you're better to reconsider or forget about understanding "beauty of mathematics" forever. Because "beauty of math" is math itself.

About FFT: are you sure that you mean FFT? Because it's merely an algorithm to compute Discrete Fourier Transform. If you want to understand the Fourier Transformation itself, here's basic explanation: http://betterexplained.com/articles/an-interactive-guide-to-...

Anyway, here're some easy-to-read books about math considered good by various people:

Hardy, "Mathematician's Apology"
Hofstadter, "Gödel, Escher, Bach"
Klein, "Mathematics and the Search for Knowledge" (he wrote many sci-pop books which I expect to be good, but I read only few of them, so I'll recommend only this one)
Сонин, "Постижение совершенства" — a good one, but I don't know if it was ever translated to english, sorry

How would that work from a free market standpoint? What I mean is, when everyone has a baseline amount of money, the relative scarcity is diminished and the market prices will inflate as the value of money(real & perceived) decreases.

I cannot recall the historical character at the moment, but I recall reading of a benevolent king(central or south american?) who give all his subjects generous amounts of gold to the effect that it crashed their economy. Anyone?

> If that's a 60fps camera (I think it is?) ...

The camera appears to be recording at a rate of about 10 frames per second. This is a way to reduce memory consumption in a portable device in which recording duration has a higher priority than recording frame rate.

AT 10 FPS, the rock's sequential positions seem consistent with a falling rock.

According to the above, ten frames per second is the highest available frame rate.

Not a meteorite until it gets to the ground.
Soylent claims to have every dietary macro-nutrient necessary for maintaining life. And it's pretty simple to look at it and say, "yep." It meets that claim perfectly as we understand macro-nutrients.

The problem is, there may be more to us than just "add macronutrients." We might need things like micro and nanonutrients. We might need variations in the kinds of proteins. The bacteria in stuff we eat might be the key to keeping us healthy in the long term. But how are we ever to know any of this unless someone studies it?

That, in absolutely NO WAY, should be misconstrued with homeopathy, which is absolutely bullshit about water "remembering" molecules that used to be in it.
The discussion here (http://libcom.org/library/phenomenon-bullshit-jobs-david-gra...) which is linked from the original post is, imo, more interesting and thought provoking.

I think most people can immediately identify with the idea of "working" 40 hours while really only doing 15 hours of hard work and 25 hours of paper pushing and procrastinating. Maybe not in your current job but almost certainly in some job you once held.

I think this is a product of work culture. There are, at almost every halfway useful company, a number of truly busy people. These people have 40 hours of things to do every week, or at least need 40 hours to properly instruct their subordinates. However it is often the case that they only really need 15h of hard work from each subordinate. The issue is that it's not culturally acceptable to say to your boss "I just did all you need from me this week in a few hours, I'm going to the beach now". So such a worker faces the choice of either speaking up and asking for more work, or dragging out the minimal work they have to do until it takes an "acceptable" amount of time. Since time is our most valuable asset the culture of a company is considered fair when people are giving relatively equal time sacrifices to the task at hand.

I know I have been lucky enough to have a manager that was not offended if I finished all of my work early and left, but 99% of people never have that luxury. It's psychological, most people don't want others to get off easy.
Because it doesn't happen on a regular basis, and they seem to have reasonable blockers in place to prevent it when they can. But, their drivers are people, and some people will do anything they can to get around that system.

Even if it's not, the relative speed is what's the issue here. The thing I take most issue with is his statement that this rock would've killed him. If it's only moving 120 or so mph in relation to his speed, it probably wouldn't kill him, let alone cut him in two.

So "Because it is on the NYT website" is your answer?

The excerpt from the book is largely the story from a single point of view, I don't see a lot of corroborating quotes, zero footnotes, and the facts are too convenient to the narrative to be the whole of the story.

Pulling one paragraph:

> As it happened, at almost exactly the moment Carlin Financial entered Brad Katsuyama’s life, the U.S. stock market began to behave oddly. Before RBC acquired this supposed state-of-the-art electronic-trading firm, Katsuyama’s computers worked as he expected them to. Suddenly they didn’t. It used to be that when his trading screens showed 10,000 shares of Intel offered at $22 a share, it meant that he could buy 10,000 shares of Intel for $22 a share. He had only to push a button. By the spring of 2007, however, when he pushed the button to complete a trade, the offers would vanish. In his seven years as a trader, he had always been able to look at the screens on his desk and see the stock market. Now the market as it appeared on his screens was an illusion.

His trading problems coincide with changing to a new technology platform and he blames the market and not the new software? Did anyone else experience a severe degredation in their trading performance? Did Lewis even ask anyone else?
Some of those graphs and arguments are terrible, and probably would help the antivaxer arguments than hinder them.
I was a ketamine user for over a decade. It really did work wonders for clinical depression, even brought me right out of suicidal hysteria and despair within moments, but it comes with severe drawbacks. It can ruin your bladder. It will sap the b vitamins out of your system, and could cause nerve damage. More importantly, it is VERY addictive psychologically. I'm not saying to stay away, but to be careful and disciplined.

Thoughts on the research: to the extent that the mind is already chemical in nature, yes depression can be a chemical issue. However, I think they are looking at it all wrong. I believe the reason ketamine (and nitrous oxide, they may soon find out) are so effective at attacking depression is because they are disassociative in nature. Looking at it as simply a chemical problem erroneously reduces what is likely a complex issue in a complex organ. What ketamine and other disassociatives do is they "loosen" one's attachment and identification with various parts of their cognitive minds, allowing thoughts and feelings to exist in their own space without having such a strong hold on a person's conscious self, or seat of awareness, or whatever. Its basically like induced meditation, and from my experience with both disassociatives and years of meditation, I will tell you that they are VERY similar and the ancient traditions of buddhism and yoga got the nature of the mind and depression more right than any of the shit I learned in university or this kind of research. Meditation WORKS, it just takes practice and discipline. Like brushing teeth, but for the mind. If you dont do it, you will get plaque and your mind will rot. A drug may help pull a person out of the depression temporarily, which is definitely useful in times when a person can't break out of the loop and is immobilized with despair, but to reduce the whole thing down to this chemical or that chemical will only continue to find chemical solutions, which are never ideal.

No, I also like eclipse the best.
Maybe the most important thing is the SWT toolkit. Netbeans and intellij feel slow and clunky, and render fonts horribly (of course if you use linux or os x then the fonts are always a little too smoothed and blurry).
Maybe 5-6 years ago eclipse crashed sometimes (or plugins made it crash), but now it hasn't crashed for at least two years.
On mac again it seems to bring up the spinning beach ball or what do you call it sometimes.
Also eclipse doesn't get in the way too much with too many autocompletes etc, it just does the things which are useful and does them fast and well.
Intellij took forever to load all its unnecessary plugins and was constantly indexing something or other. Really horrible.
> The problem stems from the fact that the DNS specification dates from 1987 ... As a result, the DNS spec enshrined that the root record -- the naked domain without any subdomain -- could not be a CNAME

This isn't due to a lack of foresight in the spec, but people's misunderstanding of what a CNAME record actually means. A CNAME says that this name refers to the exact same thing as another name, including all subnames.

You can CNAME the "bare" example.com to foo.example.org, but it would involve getting the .com nameservers serve that record instead of NS records. By having NS and SOA records for example.com, you can no longer say that the two names are equivalent. Rather than having to define a merge algorithm (eg what happens if example.com and foo.example.org both have MX records?), the RFC simply rules out additional records on the alias.

A little perspective, here, please. Humans sell lubricant specifically marketed for introducing foreign objects to their lower digestive tract. We also sell home enema kits without a prescription at local drugstores. You don't need clinical supervision. At best, they could provide donor screening to reassure you that you aren't going to give yourself a new disease. If you know the donor, you could probably do at least as well just by observing them for a period of time.

Putting someone else's poop in your colon is not that disturbing when you realize that it already had your poop in it. It wasn't exactly squeaky clean before the procedure.

Why would someone else invent it? If people decide to stop paying for the machines, or at least stop paying enough for him to suitably benefit from making/obtaining & maintaining the machines, why would anyone else fill in the gap if they're not going to benefit either?

Such technologies are common: per-unit and per-use cost may be low, but price of reaching that cost level may be extremely high. Integrated circuits are individually very cheap (!), but the machines making them cost $billions - they're not something you are, on your own, going to construct just so you can have an iPhone. iPhones exist because Apple put enormous money into making their components in such volume as to reach commodity cost.

Mr. Myne's machines may cost just a couple dollars a day to rent & run, but may have cost a billion dollars to produce to achieve that cheap cost - heck yeah he wants 4x retail price thereon because he needs to earn back that billion dollars and make enough additional profit to make the whole enormous activity worth his while.

A thing is worth exactly and only what another is willing to pay for it. If people will pay $8/day for Mr. Myne's machines, that's what it's worth.

- What's the performance impact, both in terms of initial page load and in terms of tracking stuff.

- How big is the buffer of "events" in the timeline?

- You charge per hit. Is there a way I can load the javascript from my own CDN? Does it ping your server upon load?

- What prevents somebody from going to my website and triggering a large number of "hits"?
People don't just want to do well, they want to do better than those around them. it's natural to many people (maybe not to you, but to many). I read this quote from a wall street executive in an article recently posted on HN: " “It's not just enough to fly in first class; I have to know my friends are flying in coach."

So unless nobody is selling first class tickets, people will work harder to afford them. And in order for the market to work, the seller of tickets will raise the price of first class until only ~10% of flying passengers can afford it.

So are you one of those EU critics who think there should be no free trade in Europe? Thereby sacrificing a significant amount of points of GDP and disrupting (in a bad way) the European Economy?

Or are you of the other faction which actually believes you can have free trade without the EU, and even without talking to each other? Really, the alternative is 28*27 bilateral treaties on each and every issue in international trade. More, if you include Switzerland and Norway.

I think the back and forth isn't necessary. On the other hand, the parliament is regulating the biggest single economy in the world. I'd be careful of penny-pinching at the wrong end. And the parliament isn't the biggest cost in the EU budget. Quite the opposite.
