I was just browsing through the classic "Mining of Massive Datasets" book (which is free!) when I noticed this apt passage in its introduction that explains the difference between data mining and machine learning:

http://infolab.stanford.edu/~ullman/mmds.html

> There are some who regard data mining as synonymous with machine learning. There is no question that some data mining appropriately uses algorithms from machine learning. Machine-learning practitioners use the data as a training set, to train an algorithm of one of the many types used by machine-learning prac- titioners, such as Bayes nets, support-vector machines, decision trees, hidden Markov models, and many others.

There are situations where using data in this way makes sense. The typical case where machine learning is a good approach is when we have little idea of what we are looking for in the data. For example, it is rather unclear what it is about movies that makes certain movie-goers like or dislike it. Thus, in answering the “Netflix challenge” to devise an algorithm that predicts the ratings of movies by users, based on a sample of their responses, machine- learning algorithms have proved quite successful. We shall discuss a simple form of this type of algorithm in Section 9.4.

On the other hand, machine learning has not proved successful in situations where we can describe the goals of the mining more directly. An interesting case in point is the attempt by WhizBang! Labs1 to use machine learning to locate people’s resumes on the Web. It was not able to do better than algorithms designed by hand to look for some of the obvious words and phrases that appear in the typical resume. Since everyone who has looked at or written a resume has a pretty good idea of what resumes contain, there was no mystery about what makes a Web page a resume. Thus, there was no advantage to machine-learning over the direct design of an algorithm to discover resumes.

Right. Calling someone that makes 250k a single year of their life rich (likely from selling a house, a small business, or some stock options) is as silly as calling someone who was unemployed for one year of their life poor.

The same article could be written in reverse: "Rise of the 'new poor': 5 in 5 Americans earn $0 at some point in life"

This is a great description, I've tried to explain something like this to novices before -- but this is amazingly eloquent.
I wonder if there are any rigorous studies on the side-effects of Japan's host industry (which is exactly what you described). Business seems to be pretty good judging by the number of clubs you come across in Kabukicho alone...
It's probably already bigger, but they guard their numbers. Tube sites are just portals to get you to go to a cam site or a dating site. There are fewer regulations with those sites as opposed to professionally produced pornography (2257 regs, condom use laws in LA County, etc.). You also don't have to worry about copyright infringement (executing it or defending yourself from it) with cams and dating sites.
Yes, you work for Code.org but I doubt if the president is involved you get the fine numbers.

> label David as a "defector"

I'm not seeing that. Maybe you can help?
Good question.

I fail to see how these buses are any different from:

* Megabus / BoltBus / other private bus companies that park on city streets (mentioned in the parent comment)

* privately chartered bus (for a school or community group)

Is the issue that they are crowding out actual city buses? Because I could see that would be a problem if the Google bus waits X minutes at a bus stop and people need to walk around it to get to the "real" city bus.

But if it just shows up to pick up a handful of people and then leaves, without disrupting the regular public transport, I don't see what the issue is, or why these "activists" are so butthurt about it.

As far as metrics go, I'm not too worried about syncing speed. My main complaint with dropbox is indexing - it slows my computer to a crawl whenever I make lots of changes. Enough so that I disable it the second I'm on battery power. Anyone have any insight in to how BT sync performs in this area?
The percentages for each group seem to include everyone in the higher groups as well.

I'm making this assumption based on the percentages of the 60-year old graph: 76.8%, 50.9%, 32.2%, 20.6%

I guess I was thinking about this plot like a histogram which makes more sense in a bar chart like this. Read like that, the percentages in each bucket are: 25.9%, 18.7%, 11.6%, 20.6% for the age 60 chart and 17.7%, 7.4%, 2.1%, 2% in each range for age 30

The Redis criticism thread
> Now the President is distancing himself from them for his own political reasons.

But whether the President distances himself or not is irrelevant. The agency is still nothing more than a tasked employee. So when people object to the NSA's actions they are essentially objecting to the policy and the choices the policy makers set in place.

Also when the NSA is blamed with overreach, it is blamed for not following orders within the boundaries of the law.

So if it was the first point that is the center of this debacle then both the President and Congress are responsible for the NSA's actions. If it is the second point then the NSA, the President and Congress shoulder the blame. Either way, this has nothing to do with the President distancing himself.
Congratulations to mitchellh and the Vagrant team. Vagrant is a fantastic tool for streamlining workflows, but also an amazing educational opportunity. Disposable Linux servers: Play, experiment, destroy, try again. Thank you for this, I can't believe how much I've learned.
Only one of those trips was for work--the rest were trips to see friends and family, and traveling (and a few of those were visits due simply to spurious data--it shows me visiting Canada twice, but only the Quebec trip was real. The other was when my phone apparently decided it was in Banff).

I would have loved to take the train on most of those trips, but they don't allow dogs or go where I need to go.

And this is only since mid-2010. Had I had data from before then I could have shown some decidedly uninteresting maps.
Coinpunk! I have been looking into implementing CoinJoin though. Had a discussion with Peter Todd and the Dark Wallet people about it. It's kindof a difficult proposal considering the amount of work I already have to do, but I'm not opposed to implementing it.
Looks like someone is busy setting up the narrative for raising taxes on "the rich" who earn more than 100k. This is how it starts. A whole bunch of "studies" come out, then the talking heads roll it out 24/7 on the news media and then Obama makes a speech and a bunch of people pound the table and ta da... brand new taxes for you "rich" people making 100k a year.
> $200k for a household is not affluent. Its just two people with good jobs.

Yes, and 2 earners with good jobs makes one affluent :)

Affluence is one of those words, it all matters of perspective. But I try to use the test of "would an average guy on the street" consider a HHI of $200k affluent. I think yes, they would.

Remember, that income level puts a couple in the 96th percentile.
They actually get hit less hard because we don't have enough tax brackets and the tax rate at the upper brackets is way too low: http://i.imgur.com/gogxtbv.jpg
Well I think we're about ready to get some pretty Bell Curve nonsense going here soon.

Also, you may be interested in comparing the responses here to Obama's video here and HN responses to similar videos (like the Bill Gates ad).

It's not so much about learning to code, as about learning how to solve problems using algorithms. Coding is a natural application of that. It surely is a very useful skill and teaching that in school makes perfect sense.

The problem is not that Google, Facebook, and others are "solving a problem" by providing these bus fleets. They are offering jobs on the peninsula paying more than jobs tend to pay in SF [because SF companies have to pay more for rent and ACTUALLY PAY THEIR FUCKING PAYROLL TAXES TO PAY TO MAINTAIN THE BUS STOPS], with a greater likelihood of becoming filthy rich, to people largely moving from other parts of the country and/or world, with the promise that they can work in one community and live in another.

When such employees are not being recruited from other places, they are being recruited from SF. Google and Facebook have a problem that their offices are in FUCKING BORING monoculture suburbs which young, smart, energetic people do not typically want to live in. And their big, monolithic companies aren't a great match for the culture of SF, though companies like Twitter have been trying to make it work by insisting that SF is doomed without them.

One has to ask, why do people want to live in SF rather than Mountain View or Palo Alto? Is it because those places are FUCKING BORING?

Yes. And they are not FUCKING BORING because they lack craft cocktail places, they have a monoculture that is unattractive to people accustomed to diversity.

That is why these buses are gross, and that is why it is gross that people who just recently moved to SF after rents roughly doubled think that people should just get a better job if they want to live here, because who ever lived in SF except rich people?

How can someone who moved here as a student and began trying to build a life for themselves in the bay area ever fit without basically letting Larry, Sergei, and Zuck declare the sort of job that people who live in SF can have?

How can people ever own a home in this city if the only way is by being [un]lucky and boring enough to be at a behemoth company or a random startup that couldn't easily be predicted to hit, and take a bunch of stock away?

Also, if SF becomes a place where most people who can afford to live here have to work in another city, it will be largely devoid of employed people during the day. There will be jobs serving coffee in the morning, dinner in the evening, mostly stocked by people who live in the east bay, and we're likely to see some of the crime problems that Oakland has which I believe directly have to do with this, specifically that lots of people who pay rent and mortages in Oakland have to go to another city to do so, on woefully overloaded transit systems that are struggling for funding, leaving the city largely full of unemployed people and violent police officers during the day.

SF is an amazing place and I can't imagine why anyone would only want to work here during the first and last hours of the day, when I do my best to be here as many hours of the day as possible, though I can't afford to live here.

Plus a lot of these assholes don't even like SF. It's like a fancy fucking pair of shoes for them to brag about.
>>aren't having income issues.

I had the same kind of revelation about high school. Programming and the internet allowed me to build a life outside of school that eventually became the source of my livelihood and lifestyle.
I expect there to be a fee associated with these permits.

What if the permits are issued with a retroactive start date (and proportionately large initial issuance fee)? Perhaps one that extends back to when each company started stopping in city bus stops? How would you feel about that?
> The telcos aren't going to perform an active MITM attack to decrypt peoples SMS.

Given how easy it would be to do, I think they'd at least think about it. However, it's also trivial to detect, so we have that going for us.
While the number of views may be small, the potential payoff could be huge. Drug companies advertise with doctors, give free samples, etc. for a reason.

my comment from the last time this was submitted:

> Because they spend just 60 percent of their before-tax income, often setting the rest aside for retirement or investing, he says their capacity to spend more will be important to a U.S. economic recovery.

As a salaried employee at less than $100K, my tax withholding in california was 35%. Spending 60% of your before-tax income doesn't seem to leave much room for any "capacity to spend more".
At the same time, you can argue the exact opposite: Having to know all these libraries and frameworks makes programming substantially harder.

When I was growing up, in the 1980s, I saw 10-years-olds around me code in assembler. They were not geniuses, they just wanted to draw sprites on a screen. I don't think that, say, learning CSS would have been equally attractive.
What came next for you when money started to be less appealing as you earned more of it?
No, only views which hit a stale copy of the rendered page and have to call that render() function. Normal views would (I imagine, I haven't traced it back) use the get_rendered() instead, which checks that the cached version is current and schedules a re-rendering (which obviously requires DB writes anyway) if necessary.
The parent comment didn't make a claim about legality; it made a claim about enforcement:

> If you tried to pick up and drop off someone in a bus stop everyday, you would get ticketed for it.

And I can say, from direct personal experience, that the claim is wrong.
Volatile, high-profit incomes more closely matches a market based on nature or real progress. It makes sense that high-earners who do real work are doing work that is risky. What is concerning is the 'old rich' who've managed to make obscene profits by market manipulation such as regulatory capture, or removing risk from their operations and moving it to the employees.

The irony is that the 'old rich' are required to create the more real-market-representative positions artificially, and as a result a large percentage of the new rich's work goes to keep the old rich in their current positions.

i.e. the old rich (who were once the new rich) are keeping the new rich from being the new old rich. Often this is done by keeping the new rich from using strategies and tools outside the power of the old rich, thus impeding real progress. Real progress would be outside of the control of the old rich, who, let's face it, are just too old and stupid to make good returns on new things. The general populous does this best, and if the general populous is out-innovating the oligarch, then that would be socialism and socialism is scary because informed markets don't buy sugar water and red labels.
The main problem I foresee with this is that the American school system is based on a religious school template whereby the students become very good at unquestioningly following instructions... and the whole point of coding is to describe to machines how to do exactly that so we can think about more interesting things.

I'm keen to see details of how the US government expects the programme to work. Given their track-record, particularly with the Obamacare site debacle, my hopes are not high.

Throwing in a compulsory coding course to the curriculum isn't the answer. Until a decent plan emerges, it's just phony rhetoric.
For this specific problem Object.observe will offer a better solution, but for now Object.observe is only supported in Chrome while proxies are only supported in Firefox.
Not that it matters in any way, as IE is far far behind..
The typical student loans for people graduating today is only 30k USD. Now that will be much higher for some people, particularly lots of people on the higher end of the income scale (doctors, surgeons, etc), but if we are talking about the 30-60+ age bracket then their school debt straight out of school will likely be lower than you could expect for the same school/program today.

What I am getting at is that I doubt student loans are a significant consideration for most people in the age ranges the article is talking about (from what I understand they are for doctors).

Also, most young people in the SF/tech scene sort of deal are likely looking at the typical school debt (~30k), but are looking at the low range of these salaries (100k+) starting at a much younger age. I know people that are obliterating their student loans with the starting bonuses from their first jobs out of college. (That's what I did, albeit several years ago, and only 5 years worth of tuition.)

These sort of scenarios won't get you "country-club rich", but will certainly get you into the elusive "traditional middle-class security" range. The kind of wealthy where you can tell your kid they can go to any college accepts them, can take your whole family on 1-2 week long holidays every year as a tradition, buy your kids a shitty car when they turn 16, etc. It is this sort of wealth that can prove troublesome politically. People in this range are relatively isolated from true hardship; they don't have to worry about making rent or worry about how to feed their family. They are much more susceptible to pseudo-concerns like "is my corporate chain coffee fair trade" and "what if I become properly rich, then get taxed a lot?".

Remember that HN is an echo chamber. While we can talk about 250k and pretend like it is normal, the median household income is in the general neighborhood of 50k. Most Americans will never see this sort of income. For most Americans, 250k is wealth.

I think we have the tendency to define "wealth" as "something that is beyond our grasp". The more money you have, the more money it takes to become "wealthy".

Can you not see how programming, as a skill, and computer science, as a discipline, are fundamentally different than things like plumbing and farming?

Society is on a trajectory. Automation, information processing, software. It is well on its way to permeate literally every facet of life. If there is a more direct way to position people to not be left behind in this shift than ensuring they have a basic grasp of computer science and understand they can make computers do what they want via code, I'd be hard pressed to come up with it.
Track 1 is encoded as 7-bit digits, track 2 as 5-bit digits. So the data is only redundant after it is decoded, not in its binary form during the swipe.
The article isn't talking about the ultra-rich making millions a year - it's talking about people making >$100k.

I'd guess that most people making >$100k per year are making less than $353k, where the taxes start decreasing. So they would, in fact be getting hit hardest by taxes, according to your graph.
It's actually worse than that: the article measures wealth by the maximum salary that someone is paid in any year of their life. So, if you made over $250,000 for one year back in 1999, and are now jobless, you're considered part of the New Wealthy.

The clauses are often ignored by employees with side projects or startups because these clauses seldom cause any harm. But they seldom cause any harm because these side projects or startups seldom succeed. If your startup becomes the next Facebook, everyone will be after you.

In short, by taking these clauses lightly, you are creating failure paths for yourself that begin from the initial light of success. You may not want to kill your big success even before it happens. If your goal is just to create a side income, you would most likely be fine simply because a lawsuit would cost more money than what it may recover, or you may just get some threats/scoldings.

I have heard that if your side project or startup reaches something like $10 million in revenues, your big-company employer actually becomes liable to their shareholders to recover this money from you since it technically belongs to the shareholders.

Some high-profile entrepreneurs have told me that you should not worry about lawsuits as they only come when you succeed and when you do, you have resources to take care of them. But I have also known specific cases of things doing down because of such issues (like the example from etsimm, who also responded to your comment).

By the way, YCombinator submission form includes a question on such IP issues, though I may guess everyone just blindly picks "No issues" for it.
