Thanks for the post, I am starting a role as a data analyst soon and am curious to hear more about two aspects of your role:

1. How are the dynamics between engineering team, product managers and data scientists. Understand that LinkedIn's data team plays a huge role in creating and improving features (like People you may know), how is it like at Facebook, and in general other companies?

Engineers build things, managers make decisions, data scientists answer questions

2. What are the tools you use ( I see R mentioned in the thread), what books would you recommend? I mostly write in python, use D3 and gephi for visualization.
Am also taking the Coursera course on Social Network Analysis (https://class.coursera.org/sna-2012-001/class/index) and reading the course book Easley & Kleinberg, Networks, Crowds and Markets. Thanks for sharing again.
Right, but that's considerably higher friction than downloading an app. Stands to reason that many fewer people would do it.
I've had way too many experiences driving in a city when I've just needed to run inside somewhere for 2 minutes and really wished someone was in the car with me to drive around while I'm inside rather than spending 20 minutes to find a parking spot. An "orbit" feature would be pretty useful for situations like that, and would even save gas occasionally, considering how long you can spend driving around looking for parking.

(Too bad it'll probably be a while before robot cars can legally operate without a human in the driver's seat and paying attention, though)
Yes. And in other countries the public prosecution would have brought a case and the school administrator who ordered the picture taking and the system administrator who followed orders would have gone to prison, where they belong.
I don't see this being disruptive at all. I think they will be adopted in industrial applications, such as self driving dump trucks on mine sites, where humans are not riding in the vehicle, and where there will be significant cost savings.

There is also the human factor. People aren't going to give up their livelihood quietly, and people won't be willing to trust their life to a computer.

Also, who's going to control these vehicles, government? Does that mean that the government has the power to redirect a car to anywhere they please, depending on the passenger, who has been identified by facial recognition?

Trains/trams/buses are proven, already exist, and are a much better solution for public transport.

This is the answer I was hoping for. I know of at least one solution for your ISP concerns. I think it will work very nicely.

ISP's can obviously block anything they want to block. But with bigger bandwidth and things like VOIP services on the rise I would think that means letting some regular customer UDP traffic pass in/out. In your opinion, would you think that most ISP's would not allow customers to keep some long-term UDP "connections" open on any port? I have not had any trouble with this in the places I've tried, but it's hard to know what most ISP's do. Honestly I just can't see any reason they would block a low number of low traffic UDP peer-to-peer connections per customer (the customer's social network), when you consider they are allowing things like Bittorrent which are huge network hogs by comparison and are being blatently used for the sole purpose of downloading bootlegged entertainment media from random strangers.

The interesting thing is that if we can achieve this sort of peer-to-peer social networking, concerns about email servers being online, at least with respect to mail that you send to people on your social network, may turn out to be less of an issue. Why do I say this? Because the reason you want your email servers to always be up is so you can receive mail as timely as possible. Ideally you would like to have near "real-time" mail. Otherwise, if time is not an issue, then storing messages for pickup later on, e.g. in the cloud, should be fine. But if you and I are both on a private peer-to-peer social network, all that's required to send "real-time" email (or whatever format of bits you choose) is that we are both logged in. We might leave low power machines on in order to stay logged in over long periods. I would guess this might be a much more popular form of "email" between friends and family.1 Remember the UNIX programs talk and finger?

1. Obviously there is no spam. The only people who can send and recieve mail to members of the peer-to-peer private social network are those who are logged in. Spammers can't log in. Nor can they be bothered to try to crack their way into myriad disparate small p2p social networks.
Thanks for looking guys. This site has been a side-project/hobby of mine for a while now. The past few days for me have been spent rewriting it from the ground up to be a much better site. I know that there are other beer sites out there, but I think that there is something special about making a service like this freely available and open source, and I'm really proud of what I've created.

When I worked at a consulting firm we liked a single rate. Don't paint yourself into a corner and waste your time by having a complicated set of rates especially if you are a one man/woman show. Take what you are considering as your highest rate, double it, (because if you are like 90pct of people I know your are probably under charging) and use that. (I'm only half kidding here)

The overhead to keep your complicated rate structure straight can be difficult for an organization and especially hard for an individual or one man show. More importantly it makes the sales process more complicated. You spend time laying out your complicated rate plan instead of getting them to agree to a proposal and SOW and giving you a nice chunk of money up front based on that estimate. If you are freelancing you absolutely should get a percent of the money up front especially for a new relationship. You can always offer people a discount rate for larger commitments of work if you like - now you are doing them a favor. Set the expectation of availability early for short term emergency work and don't do an hourly rate at all for this if you can help it. Get good at estimating and give them a (high) project based price that reflects your costs for bumping them to the front of the line.

Car sharing only works well for urbanites without children living with them. The rest of us keep a lot of stuff in our cars: strollers, child seats, spare clothes, shopping bags, diapers, pens, ski racks, toys, first-aid kits, etc. Even with computer driven cars I'll still be willing to pay a lot to avoid the hassle of loading and unloading every day.
I believe there is indeed a countermovement that the author overlooks. It's a generation of tools beyond HTML, CSS, and JavaScript directly where content is distributed in slide decks or a similar presentation-like format. It's great for readability, it's relatively interactive, and it's flat. Surely you're not making an app in PowerPoint, but the Web is not the only/best way to consume content.

For examples see Issuu, Slideshare, and especially Prezi.

I'd be lying if I didn't mention that I miss the days of HyperCard stacks and MacAddict CDs.

This weekend I lost myself in the mountains of West Virginia on a whitewater rafting trip. The great thing about bouncing around class 5 rapids is that you have no time to think about anything but the present. The phrase "laser-like focus" is tossed around amongst the tech community, GTD folks, minimalists, etc., but I never knew what it actually felt like until I was on the water. Getting away from the computer for long periods of contemplative thinking is one of the best activities I've done for my mind in a lifetime.

Spotify should turn this into an opportunity. Situations like this, allow users to pay-to-unlock albums, otherwise seamlessly integrates with the rest of Spotify. Virtual Currency and pay-to-win works extremely well for social gaming/zynga/et al, why not music industry?
Spotify doesn't pay much to artists because it doesn't take in much money. It has to remain competitive against piracy -- it can't charge $100 per month. I pay $10 per month to Spotify Premium and probably play 100 tracks per day -- whereas I used to pay $20 per CD that I'd probably play 100 tracks from in its lifetime.

The bottom line is that I pay a lot less for music now than I used to, and most people do, which means there's just less money from recordings in the pot that can go to artists.

It's incredibly difficult to figure out how much it costs, because none of the rent-to-own websites will give you a price. Instead, it's all bespoke, so that they can rip you off for the largest possible amount.

Example: "Aaron’s shopping cart is a little different than other web sites. You will of course get a guaranteed low price on everything you choose, but you won’t see pricing or payment info here on Aarons.com. So, you will only begin the process of purchasing or starting a new lease with our shopping cart.
If you take 5 minutes now with the easy, 4 step shopping cart process, your local Aaron’s store will contact you ASAP and provide you local pricing and availability and help you take delivery in as little as one day."

Based on the one advertised price I was easily able to find [1], they're charging about a 400% markup, over retail. This would be equivalent to a loan at about 157% APR.

[1]: http://www6.rentacenter.com/Rent-A-Center-Home.html - the $24.99 a week "RAC Pack" - for 126 weeks, total payments $3148.74 for a Samsung PN51E450 and a Samsung HW-E450, total retail price on amazon: $737.94 ($547.99 for TV + $189.95 for soundbar)
So far the stuff that has qualified for the "Emergency rate" has been along the lines of "My server/website/software is down/badly misbehaving, and a simple re-start won't fix it. I'm bleeding money, please help." It's the type of thing where I don't (and they don't) know what it will take to fix it, but getting things running again (and fast) is important. I can't give a quote without being able to see the actual situation, so an hourly rate to just band-aid the problem makes sense. I'll usually follow up with "Here's what the cause was, this is what it will take to fix it _properly_, and I could fit it in next week. Would you like to get it fixed?", which has been a great success at gaining me more work and very happy clients.

In general, they are happy to pay the higher rate because when it gets to that situation, leaving it for longer will cost them more than paying a higher rate to get it running. Once it's done, then they're usually more than happy to talk about a longer term fix to ensure that it doesn't happen again.
It all comes down to Query = Function(All data). The architecture I describe is a general approach for computing arbitrary functions on an arbitrary dataset (both in scale and content) in realtime. Any alternative to this approach must also be able to compute arbitrary functions on arbitrary data. Storing data in Cassandra while also indexing it in elastic search does not satisfy this, and it also fails to address the very serious complexity problems discussed in the first half of the presentation of mutability and conflating data with queries.

The Lambda Architecture is the only design I know of that:

1) Is based upon immutability at the core.

2) Cleanly separates how data is stored and modeled from how queries are satisfied.

3) Is general enough for computing arbitrary functions on arbitrary data (which encapsulates every possible data system)

It's not a criticism of the relational model. It's a criticism of the relational database as they exist in the world. The normalization vs. denormalization slides explain how these concerns are conflated. The fact that you have to denormalize your schema to optimize queries clearly shows that the two concerns are deeply complected.

Yes, the Brazilian legal system is based on civil law and the US one is based on common law, they work differently for example.

This is not the first decision against Google in this election and will probably result in nothing for Google and their president and workers, I have a couple of friends working in Google Brazil and life is the same as before, there's no police in the door of their building harassing them, if everything else fails he could appeal to the Supreme Federal Court who judges matters of constitutional issues, including free speech and complication involving this basic right.

Brazil does not have free speech as in the US, the legislation is almost the same that exist in France and a couple of other European countries for example, you cannot open a website containing hate speech, hosting neo-nazi websites is illegal in Brazil, hosting terrorism related websites is illegal in Brazil, the list follows, I prefer this way although I see value in the American system.

Following HN for such a long time I saw a couple of comments about how the legal system in the US also sucks and how the legal system there is a mess, nothing different from, people here in São Paulo generally idolizes the American criminal law and how it's easy to put people in jail for long times or even applying capital punishment, which does not exist in Brazil, with a exception in military justice in times of war, and yet I saw more than one discussion of how this same system in the US sucks right here on HN some months ago.

There's a point in the last paragraph, why are you generalizing? Are you a expert in comparative international law? If not I do not see how your opinion matters or how your last paragraph is valid, I used to be a grad student in the US I got the impression that Americans are over litigious and that the justice system generally benefits the rich who can pay better lawyers, not much different from here in Brazil, but that is just pure personal experience, I'm not a lawyer, I am a statistician. Must I say then that the US judicial system is corrupt? I don't think so, personally I would love to live in a world where judges are not necessary but we know that this won't happen.

And by the way in Brazil a judge is employed by the state not by a government.
I charge a straight hourly rate for all, with it multiplied by 1.5 for off-hours and 3x for emergencies. The only type of work with a higher rate is knowledge transfer.

I don't get many off-hours or emergency requests, but when they happen they are almost always events which clearly require it. Overall, it has been a great structure.
I'm guessing its much more than 400%. After all, the stores that don't post their prices online (most of them) are probably the more expensive ones
NewSQL inherits mutability and the conflation of data and queries. It's no longer 1980, and we now have the capability of cheaply storing massive amounts of data. So we should use that capability to build better systems that fix the complexity problems of the past.
The approach of prompting the user "Do you want to call this number?" is far simpler and safer. After all, you could probably use tel: links or tel: redirects or something if the frame didn't work.
No. The big record labels are not dying. Album sales are UP. And at least according to Nielsen, the big four record companies account for 90% of those sales.[1]

Nielsen's methods of measuring probably favor established record companies over independents. But the fact remains: sales are UP among the big four in 2011.

Price per album has of course dropped like a stone with the switch to digital. But so have distribution costs.

And do you know what happened when the price dropped? The number of units sold went up! This is mad, MAD, I tell you, an outcome never even dreamed of by any economist ever.

Their profits aren't quite as obscene as they used to be perhaps. But they are still making money hand over fist.

This myth that the big record companies are dying needs to stop. It gives weight to their whining about piracy. Which is the real long-term danger.

You're forgetting the ~15% improvement from pure software in the iOS 6 Javascript interpreter mentioned elsewhere. Combining those, I get 2/((2150/1864)*(1200/800))== 1.156. So a 16% improvement in IPC. That's much more in line with what we see elsewhere in the industry for this sort of increase in transistor count (c.f. Nehalem to Sandy Bridge, etc...)

Needing lots of expensive invariants is almost "invariably" (see what I did there?) a code smell. You often see big, complex classes with 10 different booleans and a ton of assertion crap, when what is really needed is to refactor the class into smaller classes which are unit-testable. In C++, I've even seen people assert that an unsigned integer was >= 0. You can just feel the quality.

The notational similarity of a broken invariant that intended to never occur vs. an error condition.

Go has a notation for problems that are never supposed to happen: panic. For other errors, there are return codes.

That's true, but sort of missing my point. Security bugs are very rarely "security bugs" in isolation. They're far more often unexpected interactions between subsystems. Here, the expectation of the browser is that it can fire a "phone number" Intent securely, because the dialer app will handle it. But the phone number intent also happens to hook to the USSD layer. It's not USSD's "fault", as the check needs to be in the browser according to the architecture. But USSD remains a booby trap because it's an unexpected legacy feature with surprising security behavior.
