San Fransisco, CA OR Boulder, Co - Full-Time - On Site

Occipital, Inc http://occipital.com

We make the Structure Sensor http://structure.io

We're looking for a backend web developer with serious Python and database skills, who also has semi-serious sysadmin skills and wants to work in our SF or Boulder offices full-time.

Us:

Occipital is equal parts science lab and software startup. We created RedLaser, 360 Panorama, and the the Structure Sensor, the latter raising over $1.2 million on Kickstarter earlier this year. We run on coffee, think in pixels, and fight for milliseconds (and millimeters). We have really good benefits including health, dental and an HSA. We provide equity to all employees. Also, money.

You:

You are a person. You are meticulous and forward-thinking. You're up on The New. You are opinionated but your ego is in check. You use Python every day, or almost every day. You know various sorts of databases, of which Postgres is one. You take your tools seriously and want to work on a small team building some crazy exciting tech. You do things the right way becuase it's the right way, not because someone is looking over your shoulder. You take complicated things and make them simple, and elegant.

We don't want a ninja, or a rockstar, we want someone who cares about the work. If this is you, then let's talk. Drop us a line at jobs@occipital.com
It adds complexity to the dev process, and I'm not sure of the benefits of said complexity. The devs still at the core need to understand JavaScript it seems like.
Wow, this is a huge red flag to me that I missed the first time I looked at the site. There is absolutely no way they're going to be able to support cloning EMV cards. Maybe they mean something else, that the'll support EMV in coin so long as the data comes from somewhere else (eg the card issues partner with them). But without stating more details it's very misleading.
The data is actually from GovTrack.us, which I suspect is also where DW-NOMINATE gets it. My script for querying GovTrack is on Github: https://github.com/DavidChouinard/congressviz

No, you have a "social network" because of your social contacts, that doesn't need the Internet at all. Also, the internet consists of more than the Web - e-mail and IM are also fine tools for maintaining your social network over the Internet, for example.

Now, there may be functionality that those services provide that others currently do not, and I never disputed that. But the original argument was that somehow that little fenced garden had a large userbase.

Other than that, I am not sure I am interested in the surveillance, lock-in (potential), and manipulation possibility that FB/twitter/G+/github/whathaveyou "provide".
> No where in the article itself does it mention "dark web" apart from the title.

Yep. I was looking for the reference to Tor and hoping that they were offering "dropbox" via a hidden service.
Marketers already have access to all your purchases.

Your bank statement has ads. Your credit card issuer sells your transactions to their partners. Retailers sell your data to data processing companies. The three big scoring companies have access to all your key financial information - and they sell it back to you (in the form of credit score monitoring services), and to marketers. DSPs allow marketers to bid on impressions at a very precise level, based on which sites you visited yesterday.

Marketer's dreams were already fulfilled years ago. They have a more data than most can handle.

Coin can become the credit card of credit cards. They could offer financing, revolving credit, analytics (like Mint), and tons of other financial products based on credit history. These are a lot more interesting - and profitable - than selling ads (or data) to marketers.

It's an obvious idea, but (apparently) nicely executed. It's a perfect acquisition target for Square. Or Visa/MC/Amex.
Referencing a URL, especially a blog, that could die anytime in documentation isn't good.
Huh, what for?
In general I agree with your argument, I just think there are a small percentage of actual sociopaths in the world (I've met one).

> I'm not sure what you are calling the premise and what you are calling the conclusion. But in general, I think that acting in your own self-interest actually results in cooperation with others and not victimizing other people. So we need to be arguing for more rational self-interest. We need to stop making the typical "moral" arguments that amount to, "If you want to be good, sacrifice for others; if you want to be happy, sacrifice other people." That is a completely horrible argument that will never result in anyone being good OR happy.

Sorry for not being clear here. I meant the premise is "Trust is a common good" and the conclusion is "sacrifice for the 'common good' and be good, or help yourself and be evil"

My data source (GovTrack) only has vote count, but not roll calls, before the 101th Congress. It might be possible to get data before that, but I suspect it's quite hard.
To Design A Bottle
Man that's so trendy now ;-)
I recently went through the process for my kid, who is currently attending elementary school in SF. You list seven schools in order of preference. If you are not assigned any of the schools, then yes, you will get an assignment that wasn't on your list, and (because nobody requested it), it usually isn't a good one.

Your odds of getting something on your list depends of course in large part on the list. SF has a number of what we call "trophy" schools, as well as a number of highly in demand language immersion programs (Mandarin, Spanish, etc). If you list only those programs, your odds of getting skunked are high. Some people do this strategically, as people who went 0/7 on their list have a higher priority on wait lists than people who got one of their choices. They figure if they get one, great, if not, they have a priority position on the wait list. Other people play it a bit safer.

My approach was to avoid the trophy schools and focus on very good schools below the radar. In my opinion, there are plenty of very good schools in this range, but this is a matter of opinion. Here's the greatschools list.

http://www.greatschools.org/california/san-francisco/schools...

I did get one of the schools on my list. That's partly luck, and partly going in with realistic expectations (even my first choice was only an 8/10, I didn't go for the 9's or 10's). It is absolutely possible to create a balanced list with a good chance of an assignment and still get skunked, it's just less likely.

There's good and bad in the ranked choice system. San Franciscans are very split on it (a recent non-binding vote to make district residence the determining factor in school assignments, prop H, actually failed by a few hundred votes, as close to a 50-50 split as you'll ever see in an election).

I think the reason article summed up the benefits from a libertarian point of view pretty well, so I won't expand on it here.
If you have ghostery it blocks stuff the site needs. This was the problem for me anyway.
That leads to another useful heuristic: since the people currently practicing in a field are making money, the current practices and norms in any field are always wrong.
It does run contrary, given "pick a percentage number, preferably one that's above COLA, and just give everybody that" which explicitly doesn't (a) differentiate improvement from non-improvement; and (b) doesn't address significant salary increases due to professional growth and changing responsibilities.
What you are telling me is completely at odds with what others have told me (including faculty on admissions committees) so I imagine it varies from institution to institution. I had a pretty compelling application a year ago and my statement (in my opinion anyways) demonstrated that I was caught up with the academic literature on a particular topic and I had done some work myself implementing and attempting to improve existing techniques. I realized that I may not have worked on that topic in particular, but my hope was that it would demonstrate research aptitude. My application was rejected from 8 schools and I contacted several to see what the problem may have been.

The GRE point I was trying to make was that since 99th percentiles are expected, the test shouldn't exist at all as it is clearly a poor filter.
Yep, totally down for us also on NA13 for the past 20 minutes.

Credit card skimming is big money. A cheap, innocuous device like this could be very interesting.
Older ones did. Newer ones tend to run over the internet. They don't tie up a phone line at either end of the connection, and the information transfer is much quicker, so in most circumstances it works better for everyone.
This is amazing. It makes me so happy to see people coming up with technology like this to make people's lives better.

I know almost nothing about the medicine of childbirth, but I think this is most likely a great technology if the WHO got behind it so fast.

Hi Dhruba, thanks for volunteering to ask questions.

What are the big algorithmic ideas behind RocksDB?

My understanding is that LevelDB is based on log structured merge trees. These can be deamortized using methods from Overmars's "The Design of Dynamic Data Structures" or Bender et al.'s "Cache-Oblivious Streaming B-trees". How did you reduce latency?

What else was slowing down databases larger than RAM? How did you fix that?

> It seems to me the real trouble is that, with torrents, that history teacher will also be giving unauthorized copies to others, who are most likely not also history teachers.

I don't see how that gets you around the problem. You would still have to litigate the fair use defenses of downloaders before you could charge anyone, and if you find a downloader without a legitimate fair use defense, how are you supposed to prove after the fact who uploaded to that specific downloader?

I also don't understand the common perception that it should be the uploader who is liable for infringement. The downloader is the one who best knows the character of the use and therefore whether it would be permitted under the law, so it makes sense for the downloader to have the liability. And liability for the downloader is the one that doesn't require twisting the rights granted under the copyright act into a knot to find liability -- downloading should be reproduction because the downloader is creating a new copy on the local hard drive. Uploading is.. what exactly? The downloader is making the reproduction/copy. No copy is ever "distributed," since the uploader's copy and the new downloader's copy never move from their respective locations. No one is displaying or performing the work in public or creating a derivative work. What does that leave that doesn't require fudging to make it fit?
Interesting stuff, thanks for putting it together.
Apples and oranges: you're conflating copyright/fair use with terms of service.

Google's not claiming you don't have a right to reuse the text. They're placing restrictions on how you use their service to access that information. It's no more a copyright claim than your local library telling you that you have to come during their operating hours.
The last url looks like some kind of political mitosis. There's probably a joke here related to the genome of government being split into two identical halves…
I believe GP is talking not about this decision but about what would have happened if https://en.wikipedia.org/wiki/Google_Books_Settlement had not been shot down in 2011.

This outcome allows everyone to digitize out-of-print books, whereas the settlement would have granted Google a monopoly on them in exchange for a fee to the Authors' Guild.

As others have mentioned, its been around for a long time now. Its for YC companies to post.
This probably works great for all-hacker teams, but I think it's worth pointing out that some people don't like typing or otherwise aren't comfortable expressing themselves in text. I work with some people who simply refuse to use online collaboration tools. Were I starting a company, I probably wouldn't hire them, but I wonder if there's something to be done about this.
I've definitely considered that, but it's computationally difficult to make it in the browser. This animated gif is as close as it comes: http://i.minus.com/ibi7p66VbETpnU.gif
The primary enhancements over LevelDB seem to be parallel compactions of disjoint ranges, to take advantage of cheap seeks on flash storage, and the ability to parameterize core algorithms and data structures to suit a particular anticipated workload. All very cool; anything else major?

Also, there aren't JNI bindings... are there?

Thanks for the contribution. Just started using LevelDB on a project, but deployment will involve fast flash storage and rocksdb looks like a worthy successor.

How much do you think RocksDB/LevelDB performance is impacted by the use of relatively coarse-grained locking? Another LevelDB fork, HyperLevelDB [1] implemented a fine grained scheme with performance benefits. Disclaimer: I am working on a (unreleased) fork of LevelDB that uses hardware transactional memory for synchronization using the new TSX-NI instructions present on Haswell processors.

> It is quite puzzling about how you are equating buying & selling on e-bay without ANY misrepresentation (Product is as described & Payment is legimatelty delivered) to a Confidence scam where the author very clearly cheated the stores by misrepresentation/lying.

I read the parent as being pretty aware that those are distinct activities and that a confidence scam is solidly across an ethical dividing line most people would agree on -- but also aware that ethics can be seen on a continuum and that there are other dimensions to it beyond whether or not deception is involved.

And that taking advantage of ignorance/misunderstanding has something in common with cultivating it.

> Is it possible that there is some cultural/educational/somethingelse deep-seated mooring that does not see this as "hard-work" and instead as profiteering?

Is it more or less likely that the parent is in such a grip, or that more of us are in the grip of a market-oriented mythos where all profit received is simply profit due from hard work?

Which belief is more convenient, and more likely to be compromised by an opportunity to benefit from it?
have you seen www.getsolo.com they have some patents on this.
I found this to be a good summary: http://criminal.findlaw.com/criminal-law-basics/mens-rea-a-d...

No, the modern optimal approach is to have a birth in a giant hospital so 1) you don't risk leaving the medical decision of whether intervention is necessary to someone without medical training; and 2) you don't risk the time lag of transferring to a hospital when a distressed baby is getting more brain damage from a lack of oxygen with every second that goes by.

I don't understand how this could work. How can they 'forward the purchase' to the appropriate card in such a way that the receiving card still sees your purchase as being from a 'gas station', or 'grocery store'.

I wish I could upvote this about a thousand times.
I can't remember the last time any merchant took an imprint of my credit card. Certainly not this year, not even on large transactions.

Given your large average ticket, it makes sense to be extra paranoid and take an imprint (mostly to avoid scammers), but certainly doesn't apply to 99% of merchants.

I don't think this would be a roadblock for them. Unless, of course, Visa/MC/Amex finds some obscure legal clause (or technical way to detect the different card) to shut them down.

Western medicine treats pregnancy and child birth like a high-risk situation, which it is. It's the same principle behind having doctors standing by at a boxing match, except the natural rate of maternal mortality in child birth is far higher than the mortality rate of even the dirtiest fight scenes.
Their suits could have logos on them, sort of like boxers' robes.
Afraid of Bitcoin? No. Afraid of regulators? I'd imagine.
for almost a second I thought you were serious.
Seriously. What's with the sudden surge of all of these one-card-fits-all startups?
Exactly. It's funny that on a network of primarily tech founders, everyone seems to be looking at this as spending money, when the real pleasure is in using wealth as capital to really "make a dent in the universe".
Pulling a con is very similar to being a hacker (the good or bad kind, your choice). You find weaknesses in a system and exploit them. Finding and exploiting them becomes a rush and pulling the con off can be just as rewarding as the financial gains (or more so). Creating a persona and successfully acting it out becomes almost an addiction.

Back when I was into fraud I was always looking for loopholes and weaknesses. Most of them I didn't exploit because the risk / reward ratio wasn't good enough. But there were still plenty of "good" ones. Store doesn't check serial numbers on returns? Buy a new item and return a broken one in its place. Store lets you do self-checkout on high ticket items? Use stolen credit cards cloned onto gift cards. Mail drop photocopies your ID? Make a fake ID with matching foreground and background contrast so the B&W copy looks black. Get online access to someone's bank or credit card with no additional info? Change the mailing address and request a new card (and PIN).
> my wealthier friends who give birth are 'over-educated and academic', and the understanding of a natural birth is a given

This is what happens when over-educated people take first-world problems to the extreme and turn them into third-world problems. Like a highly-educated acquaintance of my brother's who married a sherpa and is now upset that he won't accept her working outside the home.

> The time I've spent in developing countries, it's just anecdotal to me that a midwife is the first call for a pregnant woman rather than an obstetrician.

My father (who works in international development and has long specialized in maternal health) has spent much of his life trying to disabuse women in developing countries (like his native Bangladesh) of this habit.
