#162We (Ananas) are working on the challenge of using technology to eliminate extremism amongst other things. We will be hiring in a few months.
What sort of extremism are you hoping to eliminate??

This is really interesting. I have never heard of Terminal.com before and I'm now deeply interested. Do you hire remote or sponsor visa?
Feel free to ping me on the email address in my profile. Be forewarned, we have a pretty serious technical interview for all candidates. I would say it's not easy to get a technical job at Terminal.
Thank you. I pinged you ;)

Any hints on where I would be able to find more in the Agriculture category?
A few off the top of my head: - Trimble - Granular - Farm Logs - The Climate Corporation I work at Climate, and we work on some pretty cool science based projects to help farmers make better decisions. We are hiring for a variety of positions you can check out here: http://hire.jobvite.com/CompanyJobs/Careers.aspx?nl=1&k=JobL... If you (or anyone) is interested in a role on the remote sensing team (satellite/drone su…
Climate is owned by Monsanto (market cap USD 56 billion).

#165There are several startups attempting practical nuclear fusion, including: Helion - has investment from ycombinator, attempting D-D/D-He3 fusion, which would produce only 6% of its energy as neutron radiation. General Fusion - D-T fusion, but with a clever design that pretty much solves material issues caused by hard neutron radiation. Fusion happens in a spinning vat of molten lead, compressing plasmas with acoustic…
Pardon, I think you meant to say: http://www.helionenergy.com/ http://www.generalfusion.com/ http://lawrencevilleplasmaphysics.com/ http://emc2fusion.org/ http://www.lockheed.com/ http://www.sandia.gov/ http://www.washington.edu/ I'll send you my bill in the mail.
I place higher value on the executive summaries given by the parent than root level links. And you're sending a bill? You must be a management consultant.

#166maybe not a hard technical problem; but they're tackling (with science) a gigantic challenge i.e. the global food industry and its discontents.

I think a lot of startups are solving important problems that might not be obvious. Any Musk startup - Tesla (electric vs. oil consumption), SpaceX (building space "colonies"), SolarCity (alternate energy), Paypal (payments). You also have Uber (limiting cars on the street & oil consumption), AirBnb (better utilization of current buildings rather than building additional hotels). Even stuff like meerkat, etc could po…
Oh, FFS. Tesla has done a fine job at showing electric cars are feasible, for sure. But without real innovation and progress in emission-free baseload electricity generation (i.e. fission or fusion) it has negligible effect on reducing GHG emissions.
Anyone care to explain why I get downvoted for stating an accepted fact? Take e.g. the IEA Blue Map scenario (50% reduction in GHG emissions by 2050), which depends heavily on electric vehicles. It also requires a 320% increase in nuclear power generation.

What a name!..
Yes, they're obviously not Scandinavian (where the name means male genitalia, plural). Funfact: in the northern parts of Norway, calling a policeman a "horses penis" is not illegal, as that is a somewhat common thing to call another person. Yes, this was tested in court in 2008.
Funny coincidence, in some Spanish speaking countries kuka refers to the female genitalia. I have never heard kuka used in Swedish though. It does mean who in Finnish.

Let me answer your latter questions first: In-protocol multiplexing must be pretty high up the list of necessary features Yes :-) but how about transparent multi-network roaming Yes :-) I'm talking about hopping between different transports. Yes :-) (I was thinking of writing a much more detailed answer to above, but it's so detailed that it would be far better as a blog post... I'll post the link here for a more inc…
Let's start with the encouragement: please, please put the technical details into a blog post and publish it on HN. This is the kind of stuff I've always[tm] been interested about. > umpteen middle-boxes on the internet who won't let it through. That's all you need to know to explain the lack of industry adoption of SCTP. Heh, I've dealt with IPSec. You don't have to convince me on the futility of getting new protoco…
Now, as for "turnkey service"... I would guess you're positing yourself as the platform provider. You need to control the server endpoints to work with multi-homing; you'll have to provide and maintain the mobile app libraries, along with best practices documentation and aids for debugging; you probably want to provide a patch for wireshark (dissector); and then there's the security to think about. That's just off the top of my head.
That's a good list of issues. And yes, we've thought about each of those issues and have had enough success that a few pretty rigorous customers are currently using us in live apps.
Because this is aimed at mobile developers, unreliable latency will be a major factor. That's something you do not have control over - maybe the protocol library can help a bit, and multi-homing already mandates graceful handling of concurrent retransmits. But mobile networks are not just unreliable, they are all too often outright crappy.
Well the general issue of lossy connections, unpredictable latency and outright disconnections and reconnections (often with a different IP address) is the main impetus behind designing a brand new protocol. TCP does a woeful job here and any new approaches that limit themselves to just tweaking server side TCP are DOA when it comes to solving those issues. We'll be going more public with some of this info soon (in a couple of weeks).
Btw, checked out Cricket WC odds on Smarkets. I think you guys are spot-on on the second Semi Finals ;-)

#170Scrape.it works on building a web scraping tool that minimizes effort and time invested to quickly extract data from websites. Web scraping is simple in theory but building a tool that can work with a lot of different websites in the wild is no easy task.
I am looking for a co-founder.
