I just moved out to San Francisco and am looking for a data scientist position locally or remote. By training I'm a PhD computational physicist, but have been working as a data science consultant for the past year and a half+. I am a generalist, with a focus on analysis and simulations, but have experience across the whole spectrum of data science (i.e. data acquisition, cleaning, modeling, machine learning, evaluation, etc.). I'm looking to join a team of really smart people working on something interesting. I love learning new stuff and hearing about what people are working on.

You're probably calculating your SaaS MRR incorrectly. Here's why
It's pretty clearly the opposite. Uber has no product yet but rushed out an announcement to steal Lyft's thunder. Lyft actually has a product and at worst might be announcing it early because of Uber's move.
We could always pay people (sign a contract) before the work is produced. Seems to work fine for the other 99.9% of professions.
So, paranoia, delusions and chromosomal damage are just part of the 'openness'?

Seriously, I can imagine your mind gets altered by sticking a wrench in it (LSD) and stirring. I can imagine it might convince you that everything you know is wrong. But you'd be wrong - all I learned is, if you screw with your mind, you start thinking goofy things.

Steve Jobs was noted for his perpetual black turtleneck and blue jeans.

Thing is, the "simple" black turtleneck was the result of commissioning a top Japanese designer to research and develop an optimal outfit (with intent that it actually become the company uniform). Jobs then bought a closetful of them. ...so a prime example of the subject bought something on par with a "hoodie", but paid way more than $20-40.

If I'm gonna look for a hoodie for work attire, it would be a properly embroidered "Jack Frost" one - which ain't going for $40.

Once you make any style standard business attire, prices for "respectable" quality will fast move into good-suit prices.
It really isn't with respect to libertarian values in particular; all I am saying is that in a given scenario regardless of Ideology A, a watered down form of Ideology B that is closer to Ideology A does not necessarily represent the values of Ideology A - it is just closer on the spectrum.
This is people asking Google to stop surfacing old content about them from other web sites, not their own web site.
Uber caught wind of Lyft's announcement and stole their thunder. It wouldn't surprise me if Uber employees read Hacker news too.
"Any distance" is a little much. I'd love this just to clear up wires on my desk, and at that distance I can't imagine the inverse square law would be too much of an issue.

Across the house? Yea, that'd be a huge problem, I think.
I would've posted an area a bit younger/more residential, but I didn't know what the article meant by "city center" for SF. Moving back is on the radar: we'd like to buy a place at some point and we can't really conscience the housing prices in DC or NYC, especially considering that in our field Chicago pays as much as anywhere else.
These were not taken with any form of "camera obscura".
For Apple, quite possibly.

Was going to say definitely, but there are actually some pictures in there with Woz in a tie. Jobs bow tie, though, in those pictures, is definitely a sartorial mark of non-conformity for that era.
I think we agree, but let me explain.

> The benchmark was how does Swift go compared to Objective-C, not C

Objective-C is a strict superset of C, in other words, there's no such thing as "Objective-C, not C". This is not me being pedantic, its an incredibly important feature and selling point of the language. You are making ObjC perform with one arm tied behind its back, exposing all of the pitfalls with none of the benefits.

> In Swift you get performance that absolutely trounces the equivalent functionality in Objective-C. That's a nice thing to know.

Precisely. I think there is a great blog post about how you get certain things in Swift for free that would be time consuming/hard/whatever in Objective-C. But without making the actual comparison, we can't know or understand that tradeoff. If this also showed pure-C or ObjC++ perf, I would walk away thinking "damn, I can get 0.9x the speed of C AND have it be safe? Cool." Instead, here I'm just left thinking "ok, so Swift is faster than something I'd never do in Obj-C. Great." Then immediately I'd start asking "wait, isn't this maybe just because we're using an expensive -[NSNumber compare:] thousands of times? Maybe this can be trivially remedied by changing that call to compare to direct accesses to the internal ints?"

Edit: As an additional comment, I'd point out that you'd make an IntArray subclass to the NSArray class cluster to get both the perf and serialization of NSArray. Again, convoluted and unnecessary work, but ultimately what you'd actually do in ObjC.
I'm going to add this to my list of coin flip 'rules' I don't really care about. Coin flip in the sense that you might as well flip a coin, or perhaps a roll a die to determine the 'correct' answer for any given person you meet.

One person doesn't do business with suits. Another is a self-styled fashionista who reads all sorts of things into whatever your choice of clothes. A third is ready to show you the door because you you took your jacket off.

One person thinks saying 'I don't know.' is sign of humility and intelligence. Another wants to hear you try to triangulate a solution based on what you do know. A third thinks either of the first two answers is pure garbage and wants you to be able to recite tricky code by rote.

In general, I find these these sort of 'rules' to be lazy bullshit.

Therefore, I can only imagine that this is merely a catchy side note among the actual strategies of someone as successful and by all accounts as smart as Peter Thiel.
I completely agree with all points. I used to check-in every time I went somewhere, but now without the mayorship, badges, etc., I don't do anything anymore. I actually haven't opened Foursquare in about a week now.

Not sure why they were so excited about losing functionality and fragmenting their user base.

Really, vaporware? Considering they've launched it in private beta already and have said they plan to expand it greatly in 9 days, I'm going to say that it's most definitely not vaporware.
1) In my view the primary reason to drastically shorten copyright is so that it is easier to create new works. For example, documentaries have startling problems due to copyright, see for example http://www.nytimes.com/2005/10/16/movies/16rams.html?_r=0

2) Isn't someone who holds a copyright other than the creator (say in this example the Conan Doyle estate) profiting from the work of others?

3) Like all sensible issues, deciding the proper term of copyright should be understood as a set of tradeoffs. Longer copyright terms may encourage more creative work by increasing the payoff, may give authors more creative control in how their creations are used and so forth. Shorter copyright terms may encourage more creative work by reducing the cost of remixing other's ideas, can provide a common pool of cultural resources for all to draw on, and so forth. What is necessary is to try to balance these competing interests against each other. It is not that shorter copyright terms are "automatically better", but I (and apparently many others in this thread) strongly believe that the balance right now has copyright terms that are too long to be socially beneficial.
Date handling in PostgreSQL has always seemed ideal compared with what was available in Python. I'm happy to read about arrow.
"Right? In another couple of years it'll be "disruptive" to wear a suit instead of looking like a slob."

This might be true already.
"Is the Tea Party a “real” movement, or is it “astroturf”?
The speed at which this debate is bouncing around partisan circles is
shocking, considering how silly the question is. If a movement is astroturf if some
outside force is organizing it, then all movements are astroturf."

This seems like a non-sequitur. Grassroots vs astroturf movements differ based on what's in the best self-interest of the majority of it's members. Or in some cases, astroturf means they actually have no members - only PR specialists bombarding politicians and newspapers with letters from supposedly "real people".
The right to be forgotten only exists in certain jurisdictions. It doesn't apply to American users on an American website.
Gmail addresses with periods can't sent messages via mail clients
If any denial of opportunity counts as discrimination, then why discriminate against everyone who didn't write the book by prohibiting them from making copies? Copyright is inherently discriminatory, and any specific implementation of a copyright system will discriminate in certain ways against certain people.
Lyft has "Plus" which as far as I can tell is very similar - http://get.lyft.com/plus/ (both services are mid-sized SUV's, not vans, and claim to seat 6)
The last, and best paragraph:

At the end of the day, the trend toward informality doesn’t actually get away from the traditional business emphasis on appearance and presentation. It just replaces one standard with another that is, in its own way, just as obsessed with appearance. Still, insofar as this new bias emphasises—at least for some time—originality, independence, and substance over style, it serves a purpose, as Mr Thiel's anecdote highlights. The irony is that it still has to go through style to get there.

When it comes to dress code, slide deck preparation, demo length vs. pitch length, and what questions to expect, the answer is always the same: know who you are pitching to.

The best entrepreneur isn't the one who always wears a hoodie or always wears a suit. The best entrepreneur is the one who picks one or the other out based on who they're going to meet that day.
Ah, gotcha. Didn't they say the plan to expand on August 15th? I'd assume they'd be announcing the availability outside of the SF private beta then.
Does this mean You can split the fare with your friends (people you know) or even with complete strangers who want to share the same route as yours? Both features need different approaches and I guess the later one will drag down cost of transpiration much lower.

Traffic lights. While not directly personal or "Internet of Things", traffic lights could really use some AI. It would be fantastic if they could learn routine traffic patterns (rush hour, weekends), detect flow (green light, but no one is there), even receive traffic data from Google/Apple/etc., then automatically adjust timing accordingly. Even mesh networking with nearby intersections.

I can't count the number of times I have been waiting at a red left turn light, with a green straight light and no other cars around. Or, backed up at a red light with no cross traffic, yet cross traffic has a long green.

It is probably a complex problem to solve and suspect the biggest barriers are bureaucracy and control. Is there anyone on here that works with traffic lights? It seems like they are setup once with a predefined timing and are rarely ever changed.
Nice Article, hope you do these for other providers as well such as Softlayer, Rackspace and Digital Ocean -- all have thier quirks!

It still has value as a "brown M&M" filter [1] where you're testing for whether they were thorough enough to follow your stated criteria, regardless of whether it has any other predictive power.

Of course, even then, it's not the (non)suit per se but the fact of having done your research.

Ha. This.

I led a project to connect my company's products (large, instrumentation devices) to the 'net a few years ago to improve serviceability, tell us when things are wrong, let customers order supplies, etc. It was a big success and I've been following the field for a while. Subscribed to the appropriate magazines, follow industry trends, get asked IoT questions from LinkedIn, etc.

I still don't see much purpose for consumer devices to be connected. Big industrial machinery: sure. Obvious benefits there. But my fridge being out of something? My oven timer went off? Why?
I doubt that the value of knowing you will pass on wealth to your children when you die is the same as just selling the copyright to a third party while you're still alive. I thought that was the point of the original argument.
Just to name a few:

- Stove

- Cat feeder

- Sink

- ...actually pretty much everything in my kitchen

- Selectable thoughts

- A physical notebook

- All restaurant ordering systems. So I can get the check right to my phone, pay with my phone, tip with my phone. No paper checks.

- City streets. So I can get real time data when I'm biking that tells me a certain road is closed or if traffic is heavy. I know this exists with Google maps but I'm talking about having the physical streets connected so the data is real time.
One of the problems we had to solve is compressing the data set so you don't need to keep too many bins around. To get one more significant figure, you need to keep 10x the number of bins. Once you have those individual bins you can always merge them in the visualization, the problem is defining them in a way that covers the distribution and doesn't take up too much space.
(See above response). Sure for C++, but certainly not C. When you use a double in Objective-C its not "no longer Objective-C and actually C now". C is a part of Objective-C. Not using c-style arrays is an arbitrary limitation, and forcing one to not use the proper data structures. No one recommends using an NSMutableArray for gigabytes of ints, it is well established that it is not the proper data structure for that. That being said, I totally agree that it is better in Swift. My point is simply that the demonstration should be one of the impressive ease of use/performance tradeoff vs. a questionable raw speed comparison where you don't actually see how fast it would go in a shipping Objective-C program that used every available tool at its disposal.

In other words, this blog post could be misinterpreted to give the impression that apps will now necessarily get faster thanks to Swift. But this is certainly not true if the C version is 1) faster and 2) in wide use. Instead the argument should be apps will be more reliable at negligible speed loss, and possibly even faster (again we don't know since that benchmark wasn't done).
If you think about it, (fiction) books are even less of real life. It's a fictional world invented by someone else, and you get engrossed in a book and don't talk to anyone.

But books are old and socially admired, so no-one who complains about Facebook also complains about books.
This is a lot of fun, I enjoy seeing the relative distances/rotation of the planets from eachother. It's a little disappointing that the planet/sun scales seem to be very off, it takes away from the overall simulation.

But that's a small nitpick, great project.

Later in his words, it's the enthusiasm he saw in me to take the initiative to rectify a problem.
The main question for me is - what exactly should your co-founder do? which skills / knowledge required?
Interestingly, this was how Lyft started (as a company called Zimride). That concept didn't take off and the Lyft one did, so they shuttered this a long time ago. They've come full circle.
Downvotes also apply to "demonstrably content-free".

I suspect it was that he showed the ability to judge a situation and to adapt to it.
One piece I think was missing from this article is how dressing in a suit vs dressing casually affects the culture within a company.

I have to wear a full suit every day to work, and I hate it. In offline conversations with co-workers, they hate it too. The formal business requirement came straight from the CEO who is of the traditional belief that our suits set us apart (whatever that means). What has resulted (along with our open office plan) is a culture that is artificially stilted, both in conversation and relationally between employees. The reason I believe this to be true is comparing "normal" formal business days with the random, once a year day where we all go on a team building exercise or have to do some physical "outside" activity and we can wear jeans and shirts. The office moral, attitude, and conversation are completely different. I don't know if there is a way to quantify exactly what I am talking about, but have noticed a distinct change in our behaviors that seem directly tied to how we dress.
It's symbolic because you can only choose who to vote on out of the options presented to you.

It's pointless because (at least in the US) the government has too much power and it sells that power to lobbyists.
There's a documentary about the best Tetris players (on NES): "Ecstasy of Order: The Tetris Masters"[0].

It follows one man's journey to gather the best Tetris players in the world for the first "Classic Tetris World Championship", as well as the preparation of the players, who try to break a new record, or to reach the unattainable level 30.

If you like obsessive people and want to learn more about the boundaries of Tetris, I recommend this documentary.

Sure and then when production errors happen I'm left with having to deal with debugging a VM process rather than a User mode process :)

Enough can go wrong in the packaging and distribution that it's a real risk.

At the end of the unikernel generation pipeline I get a little Xen VM spit out that I can run. How do I debug this guy? It's running on a hypervisor but is essentially in a different environment. I'd love to be able to take code written in one environment and be 100% sure it'd work in another, but that ain't going to happen soon.
I'm not sure about the art and music making. Computers will make this too and not just better, but also personalized for your brain. I think, there will be a great depression, when even creativism becomes boring.
This is won't stop corrupt Chinese officials with money to burn, and also will play out just like the BYOD scenario for mobile phones in corporations in the US:

BYOD phenomenon:

* company issues BlackBerry or Windows 6.x phones
* executive has money to burn, likes the iPhone/iPad
* executive brings iPhone/iPad to work and tells I.T. guy "hook me up or you're fired"
* I.T. makes an exception, deals with it
* other people start bringing their iPhone/iPad to work
* corporate policy adjusts and everybody can bring iOS/Android, corporate issues iOS/Android
* players like Citrix, MobileIron, etc., have a market for Mobile Device Management

Chinese gov't evolution:

* corrupt official has money to burn
* corrupt official buys MacBook/iOS/iPad or Samsung, etc.
* corrupt official uses his stuff at work despite policy
* underlings want to show off too and bring their devices
* Hmmm, except the US gov't still depends on BlackBerry, at least DHS
Fair enough. But 'legal tender' still implies the force of fiat. Switching to Bitcoin wouldn't be the same as switching to Euros, to me it would mean a government admitting to the rest of the world that it no longer has the means or the will to regulate its own economy.
It may be time for HN to add a feature that TechMeme already offers: combine multiple links that cover the same story under one thread. I'm sure the smart people at HN have already considered it.

For instance, yesterday's news of Apple's Sep 9 launch date was shown on TechMeme as one item, with about 100 sub-links from every possible publication. They even get the primary source right most of the time, which is great.
A big round of applause to whoever did this.
Sexual organs. Enough said.
In fact, the original purpose of the business suit was to call attention away from the clothes. Fancy people in the UK call them "lounge suits", because they were originally for lounging with ones' friends.

The 'interview suit' with its charcoal grey and boring stripey tie is the most business-appropriate item of clothing I can think of. The lines of the lapel, tie and collar call attention to your face, and the plainness of the suit calls attention away from the clothes. The primary reason it's uncool to wear it is because good, comfortable tailored suits are expensive and require a few minutes' preparation. (Yet it is still cool to wear designer jeans, drive expensive cars, &c.)

I don't like the trend of streetwear becoming effectively businesswear, because it gives room for a fashion-conscious person to choose more coordinated and expressive clothes to create a greater impression, which seems inappropriate for business. Streetwear is also more distracting, the lines are less clean, and so on.
I see someone mentioned Lono. Another company called Rachio[0] has a connected sprinkler controller available for purchase now. It's connected to Wifi instead of Bluetooth which I think is interesting in the Internet of Things discussion.

This already happens in some cities. There are traffic lights in my city, for example, which adjust for trains, presence of cross-traffic, etc. The cross-traffic one is neat because a light will, quite literally, stay red forever and only change when a car pulls up to actually use the green light.

From this[0] article:

> Today, cities use computer-controlled traffic lights that adjust their timing based on traffic levels, the time of day and even the number of trucks on the road. In Los Angeles, for example, city officials use traffic management to control their 4,400 traffic lights, reducing travel time by 12 percent.

The 3 second record was unofficial in 1992. The 1-second record has stood since 1997 (and is officially unbreakable.)

The expert record of 32 is really impressive. I can't finish intermediate in 32.
