He can only buy it if someone's willing to sell it. ISPs won't sell information this granularly - not directly.
fsargent··on Healthy California Act: proposal to make findings about single-payer healthcare
It's reasonably easy to establish pricing differences relative to land value costs to account for increased rent in the area. It's almost the same way the GSA determines Per Diem rates. https://www.gsa.gov/portal/category/100120
fsargent··on Healthy California Act: proposal to make findings about single-payer healthcare
Either way you're going to be reducing rent (ie, gaining market efficiency) until you're not doing that anymore. There are testable ways to evaluate the market's ability to handle cost reductions and operate effectively. Even better that California can rely on the US and Canadian market overall to compare itself.
fsargent··on To fix L.A.'s traffic, we need tolls
With any Pigouvian tax[1] you encounter the problem of progressivity. The answer is to make sure that the tax revenues are directed towards making it easier for low income people to have better transit options. Whether that means improved transit systems or income based toll exceptions, it's relatively easy to offset the detrimental impacts that tolling may put in place.

fsargent··on Penguins inspire a novel way of making sure code in smart cars does not crash
Relevant publication: http://ieeexplore.ieee.org/document/7397214/?reload=true Can aquatic flightless birds allocate Automotive Safety requirements?

TL;DR: Penguins Search Optimisation Algorithm (PeSOA). PeSOA mimics the collaborative hunting strategy of penguins, using the metaphor of oxygen reserves as a search intensification operator. This allows the penguins to preserve energy, consuming it only in areas of the search space that are rich in good solutions. The performance of the approach is evaluated by applying it to a benchmark hybrid braking system case study, demonstrating performance that is an improvement to those reported in the literature.

fsargent··on Penguins inspire a novel way of making sure code in smart cars does not crash
Can someone translate this for me? Why do penguins change how software development works?

"They forage in groups and have been observed to synchronise their dives to get fish," said Prof Papadopoulos. "They also have the ability to communicate using vocalisations and possibly convey information about food resources."

"This solution has generic elements which can be abstracted and be used to solve other problems," he said, "such as determining the integrity of software components needed to reach the high safety requirements of a modern car."

By mimicking penguin behaviour in a testing system which seeks the safest ways to arrange code instead of shoals of fish, it becomes possible to slowly zero in on the best way for that software to be structured.

... What?

fsargent··on Ask HN: If you were to switch career, what would you do?
Yeah, absolutely. More of a "Home Economics" tint to it, but something I feel most people are missing in life.

I feel the math should be used to prove the philosophical points. It's rare that the math actually improves understanding without a novel hypothesis behind it.

fsargent··on Ask HN: If you were to switch career, what would you do?
I'd be an economics teacher. I'd love to teach High School and/or College economics. Since this is my own fantasy land, I'd be able to set my own curriculum.

  1. Why do we work? (Jobs, Businesses, and the individual economy)
  2. What is wealth, and how do I get it? (Saving, investment, real estate)
  3. Is it supposed to be like this? (Capitalism, Government, modern political economy)
  4. Systems Design (If you want to change the system, how should it work? How do we measure things that aren't money? Love, time, attention?)
I wish I'd had an education like this earlier in life.
fsargent··on Bill Gates et. al. launch massive clean-energy fund to fight climate change
Exactly.
fsargent··on Bill Gates et. al. launch massive clean-energy fund to fight climate change
It's a pity that charity is the best way (currently) to find solutions to these issues. Market mechanisms could create an incentive if only we put an appropriate price on carbon. Then industries would be falling over themselves to develop clean energy.
fsargent··on The Fake Factory That Pumped Out Real Money
True, but looked at holistically it'd be better to have the revenue go to the government, and reduce a tax that punishes behaviors we want - such as employment being punished by the income tax. https://en.wikipedia.org/wiki/Pigovian_tax
fsargent··on The Fake Factory That Pumped Out Real Money
Cap and Trade and a Carbon Tax are equivalent in outcome. Cap and trade would impose fees on everyone regardless of how much it costs them to lower emissions also. The problem with Cap and Trade is that it targets the large scale emitters rather than the item desired to be limited.

Imagine that you had five major producers putting out 30% of airborne carbon, and 50,000 minor producers putting out 70%. The cost of administering a cap and trade system to the minor producers would be incredibly expensive - the legislation would instead focus on gouging the five major producers. Also imagine that the 50,000 minor producers could very easily cut their production of carbon in half.

The price should be set to the amount of damage the externality causes. Current estimates of the social cost of carbon is ~$220 per ton. http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nc...

Cap and trade punishes large players - taxes are fair because they impose the same fees on everyone.

Cap and Trade being the least expensive way possible is also a terrible loss for good tax reform. If we implement a responsible carbon tax, the offset income can be used to reduce associated corporation taxes, sales taxes, or even income taxes.

An optimal tax system taxes things and behaviors we don't want, and subsidises things and behaviors we do want. Let's get rid of an income tax, and replace it with a environmental tax. More money in your pocket, and cleaner air.

fsargent··on Ask HN: Who is hiring? (June 2016)
Senior Backend Engineer (Scala) at SeamlessDocs - full time, onsite in SoHo, New York, NY

SeamlessDocs specializes in digitizing and automating business and government forms and PDFs. The platform is like Google Docs for PDFs. It allows anyone to easily convert any PDF into a fillable, mobile friendly cloud version that can be completed and eSigned from any device. Then it builds a database in real time of the info collected and has workflow and process automation tools.

Due to its government focus, SeamlessDocs has been able to continue to differentiate itself as THE standard in government forms as well as through its government sales funnel expertise. This allows them to avoid repetitive admin tasks and data entry; cutting costs and increasing efficiency.

--

Our ideal candidate has strong experience with Scala and writing stable, scalable backend services. Bonus points for experience with additional backend languages such as OCaml, Haskell, Go, C++ (with preference towards functional languages). Candidate should also have experience leading a team of engineers.

. You are actively engaged in software development communities, Open Source projects or projects of your own; where coding in collaboration with other engineers is a necessity. The principles of Agile development, coding standards, unit testing, documentation and communication are second nature. You’ll be successful at SeamlessDocs if you are able to look at existing code, which isn’t always pretty, and say – I love a challenge and I know how to turn that into something beautiful. You follow design patterns that lead others to more elegant solutions.

Responsibilities

• Develop efficient web services and APIs.

• Participate in daily code deploys while working on individual or team projects.

• Take ideas and concepts from the business and turn them into tangible components of the site.

• Participate in thorough code reviews with a goal of illustrating quality engineering practices and to produce the highest quality code possible.

Skills / Experience​

• Strong software engineering fundamentals. Interested in Scala not because it's the 'hot new thing' but because its type safety and functional nature enables stable growth and beautiful code.

• Experience using PostgresSQL

• Experience working with large data sets (data mining, data analytics, data manipulation and reporting)

• Experience working with a production environment with zero or very minimal downtime

SeamlessDocs seamlessdocs.com/jobs Soho/Tribeca NYC, NY

Positions: Senior Front End Javascript Engineer (React, especially).

SeamlessDocs is working to change the way citizens interact with their government. We came out of Code for America, and are supported by the GovTech Fund. We have started with the worst part of government -- forms, and we're making incredible inroads. Government Clerks can upload their PDFs, mark them up, provide signable, public place for citizens to submit building permits, soccer signup forms, or even teacher evaluations.

We're still a small team, you would be coming in as a senior front-end engineer to manage and grow the team using the best practices you choose.

Qualifications: Read this: https://medium.com/javascript-scene/10-interview-questions-e... If you can answer that, we should talk.

fsargent··on Medical Breakthrough in Spinal Cord Injuries Was Made by a Computer Program
This is the breakthrough: In the case of the spinal cord injury data, Ayasdi’s TDA-driven approach mostly confirmed what researchers already knew: The drugs didn’t work. But the discovery of high blood pressure’s detrimental effects on long-term recovery has immediate implications for human patients, namely whether the use of hypertension drugs immediately after their injuries and before surgery could improve outcomes,
fsargent··on The world needs at least 600M new jobs in the next decade for young people
It's mostly related to real estate prices. In uncertain economies investment goes into stable markets -- land and buildings. Prices increase, rents increase, people need more money to pay for their housing. Everything else gets cheaper, but housing keeps getting more expensive.

If you want to decouple these things, look into Land Value Taxes and a Citizen's Dividend.

Excellent post. I was curious about how to do this properly but always got scared off by the fear of having to actually write my own crypto code. It's a pity it's not maintained better by Google. Maybe the EFF will get behind it...
fsargent··on Liu Cixin, China’s hottest science-fiction writer
Scarcity of habitable planets is absolutely solvable with technology - space ships, stations etc. Sufficiently advanced technology may also allow people to switch to more efficient bodies, or upload their consciousness to computers, or simply different forms designed for 'uninhabitable' worlds, or space itself.
fsargent··on How do machines learn meaning?
This isn't learning by any means - this is just similarity. Machines don't understand what the words mean, nor the nuance of how to use them via this method.

fsargent··on Signal 2.0 released with private messaging support
Left button/Screen is active conversations. Right side check box blue thing is the Archive.

Swipe right on a conversation, and it goes into the right hand side. No idea why it's that way. Very odd. Why even have the option if it's going to be a first level function.

fsargent··on How the Brain Uses Glucose to Fuel Self-Control
I have done exactly this, and it's been fine. I regularly ride centuries around the Bay Area on a sugar free diet.

Your body definitely needs time to adapt to a fat based diet, but it can satisfy all your energy needs.

I've also done centuries with sugary 'energy' foods. I frequently found myself having to pull over or dangerously balance in order to keep my blood sugar high by dosing myself every 45 minutes. Your stomach churns, your teeth feel awful, being constantly in service to your legs. Burning the fat is a much more comfortable proposition.
