Ask HN: How can I work towards building a company while employed?
392 by mr_puzzled | 179 comments on Hacker News.
I will start a job as a software dev and with the job offer comes a bunch of contract clauses that basically lets the company own all IP while employed. I am from a third world country, so I won't be able alter the contract clauses. With these restrictions in place, what can I do while employed to have a better chance of succeeding when I do start a company? My plan : - continue learning while on the job - prepare for interviews so that I can apply to companies that are friendly to side projects (stripe, gitlab, github and a bunch of other such companies. Please mention companies that are ok with remote workers and are side project friendly, even startups paying $30,000 work for me) - build side projects in my free time that demonstrate my skills - maybe participate in Pioneer.app tournaments so I can network - basically work on stuff that won't become a company - once I get a job at a more side project friendly company, I'll start working on my ideas. As you can see, it's quite a shitty situation to not be able to pursue my side projects that could become companies, but it is what it is and I want to make the most of the next year or so. Any suggestions would be appreciated. Thank you.

Ask HN: What overlooked class of tools should a self-taught programmer look into
608 by nathanasmith | 280 comments on Hacker News.
15 years ago I learned Python by studying some O'Reilly books and I have been a hobbyist programmer ever since. The books went into detail and since reading them I've felt confident writing scripts I needed to scratch an itch. Over time, I grew comfortable believing I had a strong grasp of the practical details and anything I hadn't seen was likely either minor quibble, domain specific, or impractically theoretic. This was until last year when I started working on a trading bot. I felt there should be two distinct parts to the bot, one script getting data then passing that data along to the other script for action. This seemed correct as later I might want multiple scripts serving both roles and passing data all around. Realizing the scripts would need to communicate over a network with minimal latency, I considered named pipes, Unix domain sockets, even writing files to /dev/shm but none of these solutions really fit. Googling, I encountered something I hadn't heard of called a message queue. More specifically, the ZMQ messaging library. Seeing some examples I realized this was important. The step of then plowing through the docs was nothing short of revelatory. Every next chapter introduced another brilliant pattern. While grokking Pub/Sub, Req/Res, Push/Pull and the rest I couldn't help breaking away, staring in space, struck by how this new thing I had just read could have deftly solved some fiendish memorable problem I'd previously struggled against. Later, I pondered the meaning of only now stumbling on something so powerful, so fundamental, so hidden in plain sight, as messaging middleware? What other great tools remain invisible to me for lack of even knowing what to look for? My question: In the spirit of generally yet ridiculously useful things like messaging middleware, what non-obvious tools and classes of tools would you suggest a hobbyist investigate that they otherwise may never encounter?

Launch HN: Prometheus (YC W19) – Remove CO2 from Air and Turn It into Gasoline
676 by rmcginnis | 379 comments on Hacker News.
Hi HN! I’m Rob, Founder of Prometheus. We’re removing CO2 from the air and turning it gasoline, diesel, and jet fuel. Since we use zero-carbon electricity from sources like solar and wind to make our fuel, there are no net CO2 emissions when you use it. An article about us came up on HN recently and people seemed interested ( http://bit.ly/2PCPFcN ), so we thought it would be good to try to answer some of the questions we saw there and try to dive in some more to any questions that follow! The only inputs to make the fuel are CO2 and water (both from the air) and electricity. The only outputs are fuel and oxygen. One way to think about it is that making fuel is reverse combustion. The process isn’t super efficient (we expect 50-60% overall efficiency at maturity), but it turns out that doesn’t matter as long as the electricity is zero carbon and low cost. If the cost of our equipment is also low, then we believe we can not only make zero carbon fuel, but actually compete on price with fossil fuel. We’re not the first to make fuel from the air - in fact Google, Audi, Carbon Engineering, Global Thermostat, Climeworks, and labs at universities and national labs have all done it before us. What no one has been able to do so far is do it at a low enough cost to compete with fossil fuel. The thing that’s new about what we’re doing is that we have gotten rid of all the thermal processes normally used, and instead use a process that uses only electricity (no natural gas, etc) and does it at room temperature. This is a big deal for both capital cost and for being truly carbon zero. We can use inexpensive materials, which keeps our cost low, and can start up and shut down quickly, which allows us to run intermittently, matching the intermittent nature of many renewable energy sources. We can also only run when the power is at the price we want. Digging in to some more details, we absorb CO2 and water vapor from the air into an aqueous electrolyte. We then react the CO2 in the water with a copper catalyst to directly make alcohols like ethanol, butanol, propanol, etc. Both of these things have been done by many others and the science is known. Normally at this point one would have to use a thermal process (distillation) to get the fuel out of the water, and this is expensive and makes the economics really hard to get right. We don’t have to do this step thermally though, because we have a carbon nanotube membrane that replaces it, extracting the alcohols from water in a single step at room temperature. This makes a huge difference in cost. The last step is that we up-convert the alcohols to gasoline, diesel, and jet fuel. This last step is also well known and we can actually buy this step from others. The carbon nanotube membrane that makes this all work is the product of 6 years at my previous startup, Mattershift. I was developing it for desalination and water purification. About 3 years ago I realized it could do this job, but it wasn’t clear that a startup could raise money for such an ambitious effort, especially one linked to a political issue (unfortunately) like climate change. When I saw the YC request for startups in carbon removal, I knew that the timing was right, and I founded Prometheus to do it. Please let me know if you have more questions or feedback. I’ll do my best to answer any questions, but please excuse if I’m not able to go too far into details like our piping and instrumentation design, or other really specific things we wouldn’t want to help competitors with. Thanks!

The process isn’t super efficient (we expect 50-60% overall efficiency at maturity), but it turns out that doesn’t matter as long as the electricity is zero carbon and low cost. If the cost of our equipment is also low, then we believe we can not only make zero carbon fuel, but actually compete on price with fossil fuel. We’re not the first to make fuel from the air - in fact Google, Audi, Carbon Engineering, Global Thermostat, Climeworks, and labs at universities and national labs have all done it before us. What no one has been able to do so far is do it at a low enough cost to compete with fossil fuel. The thing that’s new about what we’re doing is that we have gotten rid of all the thermal processes normally used, and instead use a process that uses only electricity (no natural gas, etc) and does it at room temperature. This is a big deal for both capital cost and for being truly carbon zero. We can use inexpensive materials, which keeps our cost low, and can start up and shut down quickly, which allows us to run intermittently, matching the intermittent nature of many renewable energy sources. We can also only run when the power is at the price we want. Digging in to some more details, we absorb CO2 and water vapor from the air into an aqueous electrolyte. We then react the CO2 in the water with a copper catalyst to directly make alcohols like ethanol, butanol, propanol, etc. Both of these things have been done by many others and the science is known. Normally at this point one would have to use a thermal process (distillation) to get the fuel out of the water, and this is expensive and makes the economics really hard to get right. We don’t have to do this step thermally though, because we have a carbon nanotube membrane that replaces it, extracting the alcohols from water in a single step at room temperature. This makes a huge difference in cost. The last step is that we up-convert the alcohols to gasoline, diesel, and jet fuel. This last step is also well known and we can actually buy this step from others. The carbon nanotube membrane that makes this all work is the product of 6 years at my previous startup, Mattershift. I was developing it for desalination and water purification. About 3 years ago I realized it could do this job, but it wasn’t clear that a startup could raise money for such an ambitious effort, especially one linked to a political issue (unfortunately) like climate change. When I saw the YC request for startups in carbon removal, I knew that the timing was right, and I founded Prometheus to do it. Please let me know if you have more questions or feedback. I’ll do my best to answer any questions, but please excuse if I’m not able to go too far into details like our piping and instrumentation design, or other really specific things we wouldn’t want to help competitors with. Thanks!
