teddyg1··on Results from first US trial of genetically modified mosquitoes
Oxitec has also been doing trials in other countries for a while dating back to 2014. https://www.oxitec.com/panama

teddyg1··on Ask HN: Who is hiring? (April 2019)
Rho AI | Software Engineer | Data Scientist | Remote (US based) | Full-time

Rho AI is a team of engineers and data scientists building machine learning based software solutions for real-world problems. Our core product, Pit Rho, was created in 2012 as a tool for enabling motorsports teams to make real-time strategy decisions, and is used on race day by teams at Richard Childress Racing, Hendrick Motorsports, and more.

We have since expanded into other domains that we care about (healthcare, energy, climate change, etc.) with a mixture of products we own and services we offer. And as a self-funded and 100% remote company, we retain an enormous amount of freedom to do things our way.

We’re looking for software engineers and data scientists who want to hone their craft by building tools that actually get used, and with people who you’ll actually enjoy collaborating with.

Our stack: python / postgreSQL / react / docker / kubernetes / scikit-learn / pytorch / more…

teddyg1··on Ask HN: Are you working on interesting technical problems?
I love the focus. Starting at the base level data and working to normalize it is definitely the most difficult piece. How far back have you assembled data?

Feel free to reach out to me individually (email in profile), I'm working on operationalizing climate data like this and would like to look at this together!

teddyg1··on Google is releasing 20M bacteria-infected mosquitoes in Fresno
In this case, the particular species that carries Zika (aedes aegypti) does not pollinate any plant species in any meaningful way.

Can someone with knowledge of this particular experiment explain how they've overcome the regulations that have stopped Oxitec / Intrexon with their aedes aegypti solution? They key regulatory factors cited against Oxitec, especially in their Florida Keys trials in the past year, were centered around controlling for the release of only males (which do not bite humans), thus avoiding transmission of any kind from the genetically modified varieties, or bacterially modified varieties in this case.

Oxitec has worked for years to filter their mosquitoes so only ~0.2% of the released mosquitoes are female[1]. They then had to demonstrate that and more in many trials before being allowed to release their mosquitoes in the wild in Panama and Florida.

Otherwise, it's great that Google can overstep the other factors that would stop this solution like NIMBYism and working with county / municipal boards. These solutions are great.

teddyg1··on Turning CO2 to Stone
Not mentioned in these comments is the actual method they cite in capturing the solid CO2. The method involves bubbling CO2 through water and hydrogen sulfide, which is incredibly toxic. Not sure if there's a better way to do it, but their current process is both economically infeasible and dangerous.
teddyg1··on What we learned from failing as first-time founders
Glad it's still a side project!
teddyg1··on New U.S. FAA rule requires drone owners to register by Feb 19
When flying, spotting anything from a higher elevation is very difficult - you essentially have to track the differential velocity of the bird / plane with respect to the ground. That's the reason why generally, the right of way in air goes to the airplane with higher elevation.

Adding additional things to spot in the air, especially slow moving objects like drones, demands focus and divert attention away from flying. Other airplanes in the air are fine to spot because they move quickly, and in unrestricted airspace, generally communicate on a universal radio channel. Drones have none of these capabilities and are essentially high flying birds to avoid.

In non-urban spaces, airspace above 500ft is always a potential manned aircraft flight path.

teddyg1··on I Tried to Buy an Actual Barrel of Crude Oil
>You don't need to stop anything to fill a sample bottle.

Gotcha. I had trouble reaching people who were willing to do sampling, which led me to that conclusion.

>H2S also deadens the olfactory nerves

Going back to check my ventilation right now, haha. From what I know, the scent disappears only above concentrations in air of ~150-200ppm.

teddyg1··on I Tried to Buy an Actual Barrel of Crude Oil
Those minimum orders are astronomical it's almost funny. Does anybody actually purchase manufacturing-level quantities of goods on alibaba? Genuinely asking.
teddyg1··on I Tried to Buy an Actual Barrel of Crude Oil
I did this recently as well (though for a different purpose, chemical testing). it's even more difficult than the journalist describes. No refinery wants to stop processing or halt flow in their pipelines, and so getting WTI or Bakken oil is immensely difficult when you're not at the source. There are small mom & pop ~2-3bbl/day producers who are willing to sell their oil at a premium, however.

Ventilation is a huge problem - H2S emits a very foul smell. Quickly open and close a small bottle of crude in a room, and the scent lingers for a few minutes or more.
