Bunch | Full-Stack Developer | New York | https://bunchenterprise.com/ | Onsite | Visa sponsorship available

Bunch builds video applications for the world’s largest companies. Millions of people communicate using our technology every day.

We are profitable, 100% employee owned, and developer driven. Our team leans heavily on React, and projects often include cutting edge server technologies - think time series databases, IPFS, and IoT - to offer features for a market with unique, large-scale challenges.

We focus on a stable of core products and often extend them to customer specifications. We have recently developed applications that use drones to assess disaster sites for insurance companies, distributed systems that move huge amounts of video data across high-security networks and web interfaces that give financial organizations real-time insight on what’s happening behind markets. We value elegance in implementation and invest heavily in the user experience.

The Bunch offices are the East Village, one of NYC's most historic and exciting neighborhoods and near many public transportation options.

We believe people do their best work when challenged, excited, and well-rested. Excellence in execution forms the bedrock of our organization, and we understand that developers, like professional athletes, need collaboration and support to perform at the highest level.

Hi Rob! Is it possible to produce gasoline through atmospheric CO2 capture for less than traditional methods? Will CO2 capture be competitive in real costs?


I cannot see how you could take CO2 and make gasoline out of it using less energy than what the gasoline contains. At best, you will need to supply that energy via something like solar panels. Then it becomes a question of efficiency: how many Watts of gasoline can you produce per Watt of electricity you have? My guess is, not many.


It can still be competitive with things like tar-sand extraction, which takes more energy than you get out of the oil. It's only economically viable because energy in gasoline/oil form is more valuable than the energy content itself, due to it's ease of transfer. Air sequestration might be a viable fuel source in regions where import costs of fuel are high, but energy is cheap.


I did not know that! Thanks.

I am less concerned about economic efficiency and more about environmental efficiency. The process to set up carbon sequestration facilities will itself produce CO2. If you produce a paltry amount of gasoline because all your energy is going towards that conversion, it might take you years or decades to actually reduce atmospheric CO2.

Even more important is the fact that the gas you produce and sell will go right back into the air as CO2, further reducing your net impact. You would basically need to produce gasoline faster than people can use it. Do you think a private company can do this process and outpace the consumption of Asia and Africa? It’s a catch 22: either your process is so inefficient that you pollute more than you clean up, or it’s efficient enough that you just drop the prices of gasoline, putting CO2 right back into the air. Their option is that you produce so much gasoline that you cannot sell it fast enough. Ironically that will tank your profits.

I think doing something other than gasoline is the answer. Make fertilizer: it will help grow the ecosystem while not immediately winding up as CO2.


This is false, the net energy is positive for tar sands it is just less than for conventional oil extraction.


The ideal method would be CRISPRing up some algae to synthesize gasoline, but we're pretty far from that.


you cannot. That would be a perpetuum mobile


> Old packages that you simply don’t want to version

It’s important to think of IPFS as a way to share using content hashes - essentially file fingerprints - as URLs. Every bit of information added is inherently and permanently versioned.

This is a tremendous asset in many ways, for example de-duplication is free. But once a file has been added and copied to another host, any person with the fingerprint can find it again.

While IPFS systematically exacerbates the meaningful problems around deletion that you describe, they are not unique. Once information is put out in the world, it’s hard to hide it.


> It’s important to think of IPFS as a way to share using content hashes - essentially file fingerprints - as URLs.

That's not at all unique to IPFS though - in fact, this is what the ni:// (Named Information) schema is supposed to be used for https://tools.ietf.org/html/rfc6920

(Depending on whether the hashes being used are properly filed with the NI IANA Registry, some IPFS paths might already be interconvertible with proper ni:// format, though with some caveats. sha256 hashes are definitely supported in both, though ni:// does not use the custom BASE58BTC encoding found in ipfs paths. Moreover, ni:// does not standardize support for file-level paths as found in ipfs, but does support Content-Type, which ipfs seems to leave unspecified. Files larger than 256k in IPFS are a whole other can of worms however, as you apparently lose the ability to lookup by sha256 hash of the whole content, and thus to properly interoperate with other mechanisms.)

Also, nitpicking but a content hash defines a URI not merely a URL, since its use is not restricted to looking up resources over a network.


I've been working on Observed-Remove Map and Set implementations that replicate the native Javascript API, as well as versions that use IPFS PubSub for synchronization.

* https://github.com/wehriam/ipfs-observed-remove

The inherent tradeoffs can be challenging to explain. For example in these implementations, there are caching constraints on certain delete operations.

Automerge looks fantastic, and I look forward to more progress in the space.

Designers | Community Managers | Developers

Four out of five people report a negative experience when buying a new car and most new car sales departments lose money. Tred helps solve these problems by allowing consumers to configure the perfect new car, then working with dealerships to find it at a great price.

We are pre-release, angel-funded, and backed by some of the biggest names in the industry, including the former CEO of General Motors. We are looking for independent thinkers ready to build a company from the ground up. It would be great if you love cars - but you should love people more.

* Designers: Your portfolio should include click and touch interfaces. You want to write production level HTML and CSS.

* Community managers: You excel at marketing and support. You are excited about inventing and exploring technical solutions.

* Developers: You have strong front-end web skills and will rock our Node.js + Backbone.js based platform. You enjoy communicating with a diverse product team.

We are a small team with a diverse background:

* John Wehr, former CTO of http://flavors.me and http://goodsie.com

* Grant Feek, former private equity associate, former BMW sales, Harvard MBA

* Lead Investor Rick Wagoner, former CEO of General Motors

Where we are:

* We have been working out of http://generalassemb.ly/ in New York for the last six months

* The founders are based in Seattle until November

* We are actively looking for office space in the New York area

After years of working with Django, I choose Node because of an abundance of developers with experience in Javascript, an environment free of context shifts when moving between languages, and code portable to the front and back end of the stack. Python is much "shinier" to me, but I think Node will make my company more competitive.
