Berkeley has a hudge breadth of top ranked Phd courses, so depending on how you account for that it matters greatly. It also has a surprisingly strong brand internationally, including in Asia. So, smart people think differently depending upon where you are getting the data from. (What USA tennie-boppers think is "prestigeous" doesn't always play well in other areas, etc).
They won't present their patents until there's a big haul of cash to be extracted. There won't be a big haul of cash to be extracted until some deep-pocketed manufacturer implements the algorithms. Which they likely won't do because they understand the same thing I do -- the system is rigged.
I have a Metroboard, and definitely feel less safe on it than I would on a bike at the same speed. The big problem is the relatively short wheelbase -- it's not hard to go over the front of the thing when braking. The Metroboard controller is pretty smart and applies braking force gradually, to give you time to lean back -- but that means stopping distances are longer.

On the whole, I thought it a rather wooly way to go 2 miles from my house to the Caltrain. For trips around 1 mile or less I think it would make a lot of sense.
After reading some of the speculation about it in the online forums, I thought "Wouldn't it be fun to set up something like this as a prank?" It almost sounds like something Woz would be into...
Definitely. The jump from univariate regression to multivariate regression is a non-obvious step because the univariate approach does not generalize in a straightforward fashion.
It's a nice article and a cute history lesson... but unless you're going to be deploying that website to a production server also running OS X, you will be much better off in a variety of ways installing Lighttpd and Rails to a virtual machine and developing against that.
Selling an extra Quantified Self 2012 conference ticket
Hi - I wanted a ticket earlier today, and ended up with an extra. If you'd like it, please email me at katiebenedetto at gmail. Thanks! :)
This is a good opportunity for YM to educate their customers. I have a great mechanic who I trust and bears with me when I ask exactly what is going on. We built a relationship based on him educating me. YM could do the same for it's customers. Your cam belt needs repairing? Why exactly? Your wheels needs alignment? Why exactly? Keep a dossier on the car and what's going on and your customers are happier and have less to complain about when they get hit with a $2k upgrade because your car is 15 years old and you can't get a used radiator for your model.
I, and millions of others, don't think Google when I think content. I, do, however, think Amazon. This is the difference between Google and Amazon.
Quora Co-Founder Charlie Cheever Steps Back From Day-To-Day Role At The Company
Amazon is, like Apple, a "sell people stuff at a price they're willing to pay" company, versus a "free but we will auction slivers of your soul" company. Apple makes most of its money up front, Amazon makes most of its money... um no one is quite sure how or if Amazon makes money. Google "gives" away goods and services and makes money selling ads ... like an old fashioned TV network. Not exactly the same thing at all.

Oh, and how much net profit has Android yielded Google?
They'll just be air-cooled: 2KW motors in a skateboard are going spend very little of their time running at max load.

I of course have no idea what the average load is, but a reasonable wild ass guess is ~100W.
I wonder at which point did you ended up going on this direction, did the launch of recent businesses like http://developerauction.com/ influenced some how this decision? Would you still describe as the "online reputation system for developers" or are you going to turn around and head into a new "job market" where companies can show off their profile? what do I gain following a company? The profiles look really nice :D.
Probably the best method is to give more power to your users and let them be MODs - probably vote-to-exile? Yes, it could be abused just like the case of Socrates.

But it's definitely better than blocking IP class which hurts innocent users and useless against trolls under proxy.
I think it is especially important to note that linear regression assumes that the relationship between the variables is, well, linear, and that in the real world, it very rarely actually is.

At best, a big asterisk should come from any of these results if you didn't have someone with actual experience validate your design/proposed analyses first.
The battery casings look pretty small. What's the watt-hour number?
So, this seems fairly intuitive to me - mostly because I have been trying to build one of these for predicting strategic actions by states ie: when is x country going to launch a missile. I am curious what they are using as their heuristics for developing solutions and how they are determining confidence intervals (my guess: number of samples).

It is actually pretty easy to build a process that "fills in the blanks" the hard part, obviously is getting those blanks correctly. In my experience that takes a fairly deep set of expert opinions and coherent "causal" node programmatics which have assigned confidence intervals. Not to mention the fact that people are going to be scrutinizing this data and if it is wrong, they are going to lose faith in the system, and quickly.

When you talk about implementing this on databases however, either the blanks which are being filled need to not be critical processes which require precision or they need to iterate corrections very quickly. In the end I think this is useful for non-critical products which users can correct if necessary. If however they have a novel solution with a significant history of "right" answers, they may be onto something in machine learning.
So then, is imagined property set to be the basis of this century's systematic child abuse, much like religion was the last's? I suppose it's not the only similarity between the two.
Good thing my neighbor only uses WEP encryption on their AP.
Correct. I think it's a wonderful country in a great many ways and it would be a pleasure to live there. I was recently in Toronto and was surprised to find that it has a solid startup scene. I'd never heard that about the city, I'd just assumed it was full of back-office banking jobs for techies like me. I met some potential partners there and if/when something clicks, I'll still enjoy zero rights to be colocated with a Toronto-based team. There's the possibility of getting TN status I suppose but that's intended for employees, not founders.
Googles strategy with android is to serve ads but they do not have a model to get that to work.

Until they do that Android is not a win.
> Oh, and how much net profit has Android yielded Google?

Probably a whole lot. When my sister, who would otherwise be in front of a computer at most half an hour a day, can get an android smartphone for 150 euros and idly browse the Web all day, Google makes a shitload of money they wouldn't have if all these people were on cheap nokias.
When The Code Finally Works
And this is why we don't do statistical programming in Ruby.
I also like the idea and look, but have you thought about a different launch approach? When your content needs to be geographically dense to be useful, makes sense to limit your launch. For a non-FB example, you can look at companies like Uber, or even today's YourMechanic launch. Yes those are both service based, but it seems like you require a lot of users in one location to be truly useful just like them.

On a similar note, I put in Madison, selected car repair, and my search didn't return any results. Just kept on loading--not sure if this is due to traffic or just no results available.

Keep it up though! I can see real potential in this, I think you just need to keep tweaking to get there. I have faith :)
Most credit card processors have recently cracked down on pre-paid cards. It's almost impossible to pay for web hosting or VPSes using them now.
Or would you rather work at a place where every little change you want to make needs to be "approved", and any new ideas you wanted to try needs to be checked off by a manager, who may or may not want it implemented depending on the political situation?
Ha, totally forgot about backlift. Did you guys send out an email when the open beta was launched?

I'm looking forward to trying this out as I'm front-end developer turned product manager that can't seem to build any of that 'backend stuff'.

Have you seen any good prototypes built using backlift yet? I'd be curious to check them out.
- They are all over with their tablets trying to compete with iPad or Samsung ones, it doesn't seem to have the same focus of the original: simply a good device to consume digital content. They will lose if they try to compete like that, trying to release full-featured tablets at low margins.

Why would they lose? The Kindle Fire seems like a great device to consume content: movies, music, books, and also many popular Android apps.

- Their event is way too much like Apple's WWDC. I mean, even the slides look like they are done on Keynote. It doesn't give a good impression.

Doesn't give a good impression to whom? Do you think the average Amazon costumer cares? I don't.

> Their event is way too much like Apple's WWDC. I mean, even the slides look like they are done on Keynote. It doesn't give a good impression.

It was nothing like WWDC--there was no developer conference. It was a single presentation. That they possibly used a major presentation application to run a presentation is not very surprising. They probably had coffee in the back of the room too.
Yeah they could had focused on a mobile-first mobile site, but to be fair, if they didnt make the iso app how were they going to get a copy of your address book?
Don't iPhone users make just as many (probably more) Google searches as Android users? Or do you think that without Android, nobody would have put out cheap smartphones by now?

It is a dangerous thing to not think like a leader until you get to a position of leadership

This should be qualified. Their are formal and informal notions of leadership. You are only a leader to those who follow or report to you, but there are other beyond that scope with or for whom you work. Part of "being a leader" is knowing the difference. A 2nd lietenant is a leader to his platoon. In many ways, he's more of a leader than his higher ups.

But he does a huge dis-service to himself and his team if he doesn't integrate his team's operations into a larger context. That doesn't mean just "following orders" per se. (Although respecting formal rank goes without saying). It might just mean keeping a distinct identity for good morale and "brand image" for his platoon, however subtly (reliable, good to work with). So when assignements or opportunities arise he is well placed to get his pick of the litter.

Likewise, this idea scales. A CEO needs to maintain such a position with his company in the market place. And a similar position in the minds of his investors relative to their other portfolio companies, etc. So, you don't outgrow this. You are never to young. Or too old. Or too successful. Its just a question of scale and peergroup and mental frame. Everybody has a boss. etc.

So, a leader knows how to exploit his position. But he never ignores it, images it, or forgets it. He is aware of it and works to improve it. And he keeps this all in proportion to the scale with which he is endowed with both respect and authority.
I _would_ have been surprised, but I saw this on their homepage:

"2012-09-09 in Redwood City CA

Whitney worked on 2000 Ford Mustang to do Tail Lamp Bulb - Driver Side"

Whereupon I remembered that just like most people don't whip up a quick Perl script to "fix" things on their computer, there people who ring up companies and pay them to replace light bulbs.

When you're the sort of person who's happily scheduled a Saturday afternoon to pull the engine out so you can replace the clutch, it's easy to forget that even the most trivial of car maintenance tasks are things that many "regular people" choose to pay someone else to do rather than learn how to do it themselves.

(But I'm still thinking to myself "You paid someone to come out and replace a lightbulb? _Really?_)
This sounds like a special kind of hell. I don't think I'd fit at all.
Ask HN: railstutorial equivalent for PHP framework?
Is there a tutorial along the lines of Michael Hartl's Rails Tutorial for a (widely used) PHP framework? Obviously there are tons of tutorials for e.g. Codeigniter, CakePHP, Symfony, etc., but I haven't been able to find one that is as extensive as Rails Tutorial is. Ideally, I'd like something that takes you from nothing to building a complete, functioning application with at least a decent amount of complexity.
Sorry I forgot to mention, after I declined the reduced rate and told them I would not be taking the position, they countered with a rate that was %10 below what the original offer was, stating that no one can reasonable expect to gain a 35% increase in salary by just moving jobs, but I was underpaid at the job I was at (A start-up that did not have a lot of capital) and the rate, I was looking for was only slightly above market. When I refused that, they then came back with the original offer and when I refused that they came back with %10 above what we had agreed on. I did not let them drag it out any further and notified them that I was taking another offer. The thing was, their client was a large online travel company and I have worked on a lot of the travel systems people use every day. My background read like the job description they where looking for. So I am sure they had to do a lot of explaining as to why they lost the perfect candidate. Their client is a household name in travel and they where extremely happy that I was coming on-board, I am sure they held their clients feet to the fire with my background and where just looking to squeeze out more profit by taking it out of my end. They got greedy and it cost them.
Great post, I wish our startup CEO would read this as well.
Yeah 8 million Nexus 7s sold is what I heard somewhere. Only reason to buy Kindle Fire over it is if you want the option of a bigger screen and you watch lot of Amazon instant video.
Probably more? As far as I know, there are more Android devices in the market than iPhones.

"In my opinion software and programming skills are worth LESS THAN NOTHING if they don't have a business idea to monetize them... "

Tell that to the developers that Facebook, Google, Twitter, etc are fighting each other to bring on board. The skills are worth a job with a guaranteed paycheck.

"And last time I checked, my programming colleagues rarely possessed valuable insights into what problems non-programmers are willing to spend money on."

Nobody possesses this without putting in the legwork to see if the idea will somehow make enough money to be worth the effort. You do the legwork and from that feedback, decide to keep moving forward, drop the idea, or pivot. The key is getting the process started. Sure, different people have different industry knowledge, but nobody can predict success from the beginning.
> Mark is one of the premier CEOs of his generation. Removing him would be completely insane. He is, by far, the single most responsible for having created a $60 billion company, something few can ever even hope to do.

There aren't many CEOs in his generation (of large companies) so that's not a great comparison. Facebook is also a $40B company, it has dropped like a rock since the shares became liquid. How much lower before his leadership is questioned? With the lack of growth and low profits I could easily see another $10-15B dropping off in short order.
Google doesn't have a strategy to serve ads on android? sure they do, it's called a web browser. Google has the largest ad network on the internet, and just about every time you view a webpage google gets a cut of it. It doesn't matter whether you use an android device or an iOS device or a windows computer or a potato, google makes money.

if google can encourage people to use the internet more by selling smartphones, they win. The point of android is not to cannibalize iOS market share, it's to eliminate the dumbphone. They don't want anybody to ever be without internet.

FTA:

"If you really are a law-abiding citizen with nothing to hide, then why don't you always send your paper mail on postcards? [...] If you hide your mail inside envelopes, does that mean you must be a subversive or a drug dealer, or maybe a paranoid nut?"

Whenever I try to explain the importance of privacy (online and in real life) to family or friends, not surprisingly, the most common retort to this is: "I have nothing to hide". When I counter this argument and explain why privacy matters, usually by giving them instances from day-to-day life where they want their privacy respected but don't think about it that way, the message gets across quite clearly. There is this paper [0] "'I've Got Nothing to Hide' and Other Misunderstandings of Privacy" which dives deeper into countering this argument; it's a very interesting read.

You're comparing apples and oranges. If you optimize for a mobile browser, you can target every modern mobile platform simultaneously, and most of your work overlaps with making your app work nicely for people on laptops and desktops.

If you go for a native app, you'll have to practically start over for every operating system.
it is like that model. the only difference is that we dont ask our mechanics to compete. we set the fair price for them so that there is no bidding.

Why wouldn't the slides be done on Keynote? Keynote is an excellent presentation app, and it's not like Amazon makes their own presentation software that they ought to be using instead. I can't understand that comment at all.
Hence using a function to extract that and then indexing the function's output. That can be done in PostgreSQL right now.
> what about the Nexus 7? I thought they were being sold faster than they could be manufactured.

The implied statement is compared to iPad, nobody is buying Android tablets.

They might be selling faster than they can be manufactured, but it's still a tiny fraction of iPad sales. All of Google's revenue is a tiny fraction of iPad revenue.

Instagram Has 100 Million Users, Says Zuckerberg
Android is winning for Google in a massive way once you understand their goal. Google's Android and even Chrome strategies are that _no one_ should win at the OS/platform level. They never want another Windows, or Mac, or IE, or anything that prevents them from leveraging the open web because it's fronted with proprietary code that can block them.

The best way to win at that game is to either force the market to adopt the system they can manage ("with Google" approved Android phones and the market) or make the web the only worthwhile source of truth among a hodge-podge of OSes that try to bolt on proprietary components. Even the major commercial forks of Android have not yet proved to derail this from succeeding.

I hope that comments referring to obvious nuisances as "awesome" will be deleted.

Here's the problem, as no one has quite caught on yet: The public transport areas consist of two main areas: Those for street-legal vehicles (cars, motorbikes, bicycles) and pedestrians (walkers, wheelchairs, baby carriages). There is simply no place for semi-powered vehicles on sidewalks. A moped or segway or motorized skateboard is an absolute nuisance on the sidewalk, and is a danger to everybody on the roadway. It doesn't fit outside of a mall-cop context.

Zuckerberg: Spotify, Airbnb, Nike+ And Runkeeper Are Killing It
Good point. By 'best tooling' I'm mainly thinking about two things:

- How easily can I debug things if something breaks?

- In case I'm not happy with a certain behavior is it a dead end or can I simply swap out a parameter / function / module (in that order)?

These two aspects are IMO essential for choosing any development environment if I have the choice. This goes for web development too, which is why I'd prefer something like Django over something like Joomla for example. I don't even care so much about performance at that point.

Do you agree with me that at least in case of iOS, native beats html+js+webviews in those two points?

I mostly agree with this, because I do like Ruby even though I don't use it.

The missing link here, and the reason Python gets more love from the data community, is that Python scales down to the smaller data sets as well as it handles big ones. (Not sure if you ment it couldn't, but the distinction you make implies that.)
