Serendipity - just the other day I was replying to a comment about education and IQ and explained I didn't believed in ethnic differences of IQ, but also in IQ altogether - http://news.ycombinator.com/item?id=4680279

At least looking for "dumb genes" is more plausible, because if IQ is an aggregate of multiple functions, some functions could be separately damaged

Copy paste:

The current perspective of IQ and ethnicities show that while there might be slight differences, they are dwarfed by the differences in the education process.

Regarding IQ:

First, I don't believe that IQ exist as a measurable quantity - IQ is too many things thrown together in a single bad. Tests group together various things which may be handled by different subsystems in the brain. If there is something called IQ, it's an aggregate.

Anyway, if there was such a unique quantity, actual data shows a progression of IQ scores in time - therefore if the tests are considered accurate and unbiased, it must be a "quantity" that can evolve based on the society a person lives it. It should then be considered not as a value, but as a function depending on a variable called society.

I do not know if studies have tried to measure the accuracy of repetitive measurement in low education adults enrolled in a learning program. If there are such studies and if they show inconsistent result (ie any change of IQ), then IQ should be considered as a function of 2 variables : f(society, personal experience).

Now, even if we consider that at a time t it could be accurately measured and that societal bias could be removed, considering how other qualities (such as determination, work ethic, consistency, creativity, competitiveness...) influence the outcome of any human activity, it seems foolish to rank people based on just one quality - especially if we don't know the other values, and their individual ponderation in the end result.

This ponderation could also be different depending on the activity, and IQ provide an absolute advantage in some activities (rhetoric?), but say determination would give an absolute advantage in other activities (startups?).
Two things caught my eye straight away:

50 words of youthful arrogance. Seniority is not so one dimensional. In addition to the hard skills (algorithms, patterns, best practices, etc) there are also soft skills:

1. Managing people
2. Managing time
3. Office politics
4. Understanding the big picture (beyond the technology)
5. Perspective

I could go on but would rather see others contribute here.
I'll let onlookers decide whether this is a discussion of politics on Hacker News (disfavored by many of the users who have been here longer than I have) or a discussion of something else. On my part, I'm curious about one empirical question: Richard Branson claimed in his blog post on the current law in Portugal (which "decriminalizes" marijuana but still treats marijuana possession and use as an administrative offense)

http://www.rollingstone.com/culture/lists/top-10-marijuana-m...

that marijuana used had declined since Portugal changed its law. That's an interesting claim. Do we have strong evidence from before-and-after policy comparisons in other countries that use of marijuana declines if use of marijuana is responded to by administrative sanctions rather than criminal penalties? If so, that would be food for thought for people like me (a generation older than most HN participants) who have seen a lot of promising young people in two generations "burn out" from marijuana use. Criminal approaches to social problems are harsh and expensive. If they are also less effective in dealing with reducing marijuana use than administrative approaches, and voters can be convinced of that, perhaps there is a path forward toward reforming marijuana laws on the basis that marijuana should be neither casually used nor a ground for imprisonment. (I think the actual enforcement practice in my state, Minnesota, largely is of the form of diverting users of marijuana to drug treatment programs.)
ah, I was mistaken there.

Yes, and it's cool, but not as awesome as the demos make it seem.

There are basically three major downsides:

1) It's another at least $399 x 2 as a single developer to use (but you can develop against it for free and only buy the license when you want to deploy). Professional licenses are more expensive than that.

2) The runtime can take a long time to load. 3-5 seconds for some apps. You can create a splash screen to mitigate this, but it's a *t experience when you do an a/b comparison on a native app and a mono app (this time is basically while it loads the runtime).

3) 3rd party library support sucks. It just doesn't really exist; if you're used to pulling nunit, ninject, shouldly, nhibernate, nsubstitute, etc. into your project, forget it. A handful of libraries have been ported to the touch and android runtimes, but most of things you'll look at either won't work or you'll have to recompile manually (to be fair there are a fair few that are easy drop ins; Dapper works like a charm for example).

That said, you get some pretty cool stuff: you can separate your core application logic, including database access into its own library and share the code between your various projects. Fix once, fix everywhere.

You can have common unit tests that you can run on a non-windows server.

It's vastly more productive (than writing two code bases in objective c and java).

You can develop without using visual studio~ <3 (some people see this as a downside; it's not to me. VS2010 is rubbish as far as I'm concerned; it crashes, freezes, loses my work all of the time. For all that I love resharper, I'll take monodevelop in a second thanks).

Overall; if you can afford it, do it.
> we can actually get into the datacenter to fix it.

But better and faster than Amazon?

I'd rather spend three hours at home saying "Shit. Well, we'll just wait for Amazon to fix that", than dropping my dinner, driving to the datacenter, and spend three hours setting up a new instance and restoring from backup.

The counter-complimenting (but not contradictory) point is that it's also true that you could create a business, especially a purely software-based business in terms of how it scales, and it could hit only say $1M or even $200k in revenue or profit each year, and that would be a huge success -- as long as you kept the team small, the ownership in your hands, etc., ideally as close to 1-2 people as possible even. Getting say $200k/year of mostly passive income would be a huge life-changing state of affairs. We don't all need to become GitHub or Pinterest or Facebook, etc. In business, a homerun is relative. FU money for a single founder with 100% ownership is pretty small in the grand scheme of things.

Good observation! It is actually a seven-day smoothing to offset some weekly periodicity, but the backward influence is very limited. We tested this with a hourly granularity without smoothening (the curves become really fuzzy), and it shows very similar results.

The conflict of interest argument is bogus. There's no conflict of interest between a dealer selling small cars and large cars. Or between those quipped with automatic transmissions and manual transmissions.

A more valid reason is that car companies should be able to sell their products anyway they like. The purpose of government is not to hand out protected status to existing merchants.

Of course, I can't pretend that government isn't already giving Tesla a lot of handouts.

Beautiful comment, both insightful and self-aware. I wish this was an article so I'd look through your blog; instead I'll have to make do with looking at your HN comments and try not to be a creeper.

I went to the event with a couple friends (them: corporate + quarterlife-ish crisis) and found the event to be heavy on the inspiration side, with the constituency consisting of those hungry (students, underemployed folks) and those who are in the process of "killing it" and looking for new acolytes.

I had a mildly unsettling feeling that, at the end of the day, like any other domain that celebrates superstars, this celebration serves the interests of the investors who want and need that kind of competition to hone the best of us into market-disrupting entities. And while the interests are completely understandable, they are maximized towards extreme outcomes... good and bad. Some would see it as tough love; others… need to see it.

And to be fair it is what it is -- the ability to efficiently bring about change makers is a net positive to society as a whole. But the vision and expectations of many people in MemAud that day were probably on the prize of greatness and billion dollar valuations, not in seeing what constitutes passion, work, and self-awareness. (Many speakers touched on this, though perhaps it's just poor sampling on my part to the people I interacted; it left nary a mark on them.)

I guess if I had to sum up my thoughts and highlight some advice from SS as a startup survivor (Bellyup School, if you will):

Things are always harder than they seems (Marc Andreessen touched on this with his MJ story).

Dedication does not preclude optimization (focus on your startup only after you get the commitment in terms of users or funding -- see Zuckerberg/Livingston stories on both).

Work hard, and be luckier/opportunistic. For every Dropbox that nailed the vision/execution, is most every other startup that pivoted a bunch till they found their niche.

Hrm, I gotta admit, now that I'm reviewing things, pretty much everyone has warned of how much things would be difficult... but somehow it just doesn't stick with most of us. Caveat emptor. :)
The idea of video timelines corresponding with external actions to create an immersive experience is definitely not new although its always good to see anyone trying to move the ball forward. I know advertisers get all wound up about the potential of this stuff.

I do find it kind of disappointing that what is a decent and relatively mainstream tech demo is featured through TED - I don't know just doesn't seem TED-worthy to me personally. Looks good though.
Glad I could help. This post was mostly a stream of thoughts, and it contains errors and approximations. I'm preparing a real article on the topic. Hopefully ready in a few days.

Why e-voting is on the decline in the United States
> Otherwise the heap will grow until it reaches close to full before the GC does a stop-the-world style collection of the old generation.

Most real applications will be using ConcMarkSweepGC(or G1) and ParNewGC. With these collectors the JVM won't just burn through all the memory and halt the world unless you throw a workload at it which the GC can't handle with its normal GC cycles.

The GC makes small sweeps regularly but the duration of those sweeps is limited to ensure relatively consistent response time. If you were creating and throwing away so many objects which were promoted to the tenured generation that these small, time limited, GC sweeps couldn't keep up, then you would see the heap grow to its maximum and a 'stop the world' GC would take place. In practice that doesn't happen in the vast majority of workloads.

Clearly pg should release the dataset and institute a annual round of hn golf where participants compete by recreating hn and trying to get the best performance for a given (changing) deployment target (SSD vs HDD, different RAM & CPU).
So on one hand this is a nice little framework, on the other hand using html5's timeupdate to load things dynamically based on approx timestamp isn't exactly a new idea. This is definitely going to popularize the concept due to the lower barrier of entry.

On the other side of the same coin: HN gets 120k uniques per day (as of October 5, 2011 - http://ycombinator.com/newsnews.html ). So it will take another 1,199 people who've had accounts closed to put the ratio at above 1%.

Of course, this is all incredibly blatant misuse of statistics. What we really need is a poll.

"Do we have strong evidence from before-and-after policy comparisons in other countries that use of marijuana declines if use of marijuana is responded to by administrative sanctions rather than criminal penalties?"

I don't think this is a fair question. What's important isn't what percentage of people are using one specific drug, or even abusing one specific drug, but rather how healthy their overall patterns of drug use are. If marijuana were legalized tomorrow and everyone who currently smokes cigarrettes switched to marijuana then obviously there would be a huge increase in marijuana use, but it would be great news from a public health perspective.

Similarly, in ~2020 when MAPS (maps.org) gets FDA approval for using MDMA to treat PTSD then we will see more people using MDMA, but this will undoubtedly be a good thing.
Yeah, I think the biggest danger is paying too much attention to what other people are doing. It's not that you can't learn from success or failure, but these days that information is far too accessible. The talent and conditions that lead to success in one case are probably completely inactionable for anyone else by the time the story is told.

What you really need is to hone your ability to recognize success and failure on a minute-by-minute basis in your own startup.

The engineering practicalities around the storage and transmission of hydrogen mean that it's a bust.

Prediction: iPad Mini will be priced at $249.

- Apple has traditionally been willing to eat into their margin a little bit when facing competition & establishing a new market

- We know that the Nexus 7 & Fire HD at $200 don't make a profit for Google & Amazon, but they do make a small profit for ASUS & Quanta.

- According to rumours the iPad Mini is lower spec'd than the Nexus 7 (1024x768 screen rather than 720p screen), primarily, but it will probably also have less RAM, dual core vs quad core CPU, etc.

- Apple gets better prices for their components than their competitors do.

- combining the 2 above suggests that a $160 cost base is a reasonable guess. (the BOM would be less than that).

- $250 gives a very Apple-like margin of 40% given the above.

Apple is having trouble with rumour control. The traditional mechanism to deal with rumours if they can't be squelched at the source is disinformation. Given their supply chain, it's quite difficult to control the hardware rumours, but price rumours seem a lot easier to control with disinformation.
I discovered when I was in China that Amazon will not sell music to you there (interestingly, iTunes will). I don't remember whether or not I had the same problem with ebooks. However, solving the problem was as simple as visiting them from a US-based IP address. (Granted, my credit card was based in the US, so that's a hurdle I cleared implicitly.)
The "related" videos are likely from youtube's shit related videos system.

Youtube, while the largest - is a fucking nightmare of a service. HORRID buffering, zero relevance with videos, spammy ad overlays etc...

Stop focusing on youtube lack of everything and focus on the fact that this idea is a BRAND NEW service that looks like in a years time will kick everythings ass.
Christian cheapsale

I am, at least to some degree. My back-of-the-envelope calculations a while ago suggested that ebooks are cheaper to produce than paper books, just by not as much as people probably imagine. (My figure then was 25% less, although I confess I don't remember how I came up with that now. It may have been a cocktail napkin.)

There are certain fixed costs which remain the same no matter the format: you have to (or at least should!) pay the authors, editors, proofreaders, artists, and cover designers the same amount no matter the form because they're doing pretty much the same work. And while ebooks don't have typesetting/layout processes identical to physical books, they still have them. And if you don't want the ebooks to look like ass -- something that a lot of big publishers clearly don't care about yet, unfortunately -- it's not going to take all that much less time, particularly if you have to prepare them in multiple formats; you have to do a "final proof," ideally on the actual devices you're targeting.

In practice, all of the costs above are generally much more of the production cost than the actual printing is. The biggest savings you have with an ebook isn't from not paying the printer, it's from not paying the distributor. But there's still a catch there: while you're not giving 50% or more of the cover price to the distributor the way you would if you were trying to get the book into Barnes & Noble or what have you, you're still giving 30% or more of the cover price to the retailer. (And you have to pay attention to the "or more"; you may be paying a middleman like Lulu to get you into some of the online stores, or you may be paying Amazon's bogus "download charges" in addition to their stated 30% cut. Assuming your sale qualifies for their 30% cut bracket, rather than one of the higher ones.)

There are no preset rules for these kind of things. I used to hide things and use "tactics" but recently I've tried being completely open and transparent.

Have conviction in whatever you do. For me the most effective way is to be completely open, share with each party the offers I already have and transparently share with them the pros-and-cons for joining them.

It's important to not just try to sound genuine but be genuine. Involve them in your decision making process, invite them to explore all options.

But once they've offered you everything they can, sit back and take a decision that serves your best interest.

By offering the option to do either by month or a 1 time fee, your customers are doing the following:
1) Calculating number of months to wedding day (since they likely know the date)
2) Deciding which is cheaper
3) Purchasing the cheaper option.

*You are probably also losing conversions to people who decide to wait to save money, then just forget to purchase.

I'm not suggesting you do this, but just think about what would happen if you priced it in the opposite way. 6 months before the wedding, $80, 5 months before the wedding $90, 4 months before the wedding $100 etc.

My guess is that you may end up making a bigger $/user, and may even increase your conversion rate.

Looks like a good site and like you are offering real value. Best of luck!
