Phonebank to End the War on Marijuana

Huh; so desalinated water costs between $0.001 to $0.008 depending on the cost of the power.

I pay about $0.0136 / gallon so almost 10x the cost of producing.

Seems like (for non-agricultural use) we will be able to afford desalination -- I guess the real issue will be agricultural uses which are predicated on free water.

For what it's worth; `eslint-plugin-react` has been around for a long time and seems to support running in very old versions of Node.JS (back to v4[1] apparently! tho I can't find anything documenting that for sure.)

I was surprised to learn that Object.values is only supported in Node >v7, Object.fronEntries was added in v12, etc. So for this project maybe the polyfills are needed.

Eggspensive 3 years ago

Tofu scramble might be a little more expensive than egg-based version but 5x seems an exaggerated figure to me.

A 14oz package of tofu is probably the equivalent of 4 eggs and costs $2-3. So maybe 1.5x the cost of egg-based version. (Here's a great basic recipe https://www.budgetbytes.com/vegetable-tofu-scramble/)

Also, if you examine your diet you will probably find that you don't need to replace eggs with tofu 1:1. There are plenty of other ways to get protein (e.g. lentils, nutritional yeast, even whole wheat bread has protein).

Eggspensive 3 years ago

My wife and I started a vegan diet 6mo ago and while there was a transition period, it wasn't nearly as difficult as I expected.

If you're feeling the egg prices I'd encourage you to find ways to limit or remove eggs from your diet. It's easier than you think! Egg replacers work wonders in baked goods and a tofu scramble is similar to scrambled eggs.

Storage will be a solved problem once everyone has an electric vehicle with a 65kWh battery sitting in their garage. Power your home overnight from your car, then recharge during the day when the sun comes out.

If you have a large home or need to always have a fully charged car, spend $15k on a home battery.

We need to get out of this mindset that electric utilities will provide unlimited power at a fixed price. With some investment from individual homeowners we can reduce peak to average ratios for utilities and make it much cheaper and possible to use intermittent green energy sources like wind and solar.

Try this: s/women/people/g

If taking a break to focus on parenting was more acceptable, anyone (man/woman/nonbinary) who wanted to do this would benefit.

Many careers are built around this idea that you spend 5-10 years, with no breaks, in your late 20s and 30s working on something. What if taking a substantial chunk of time off was more common (for anyone)?

I think the indictment is straightforward: BitMEX provided banking services to US customers without implementing Know Your Customer and other required anti-money-laundering safeguards.

Being a "fintech" product doesn't exempt an operator from the law: KYC is the law on the US.

I'm surprised there haven't been more indictments, since I'm sure other exchanges have operated fast+loose w.r.t. AML and KYC

Pro tip: to build in a line before 1.1, click to place a belt and then move the character in a cardinal direction with one of W/S/A/D while holding the mouse button down. You can lay a straight line of any item this way (including e.g. pipe, etc)

I think the IRS number might be spot on.

Quick math:

   ($25,000 cost to buy car new - 
    $4,000 residual value at end-of-life
   ) / 100,000 miles usable lifetime = 

   $0.21/mi depreciation of value

   $3.22 / gallon * (1 / (17 mi / gal fuel efficiency)) = 
   $0.19/mi for fuel

   Maintenance:
     $40 per oil change / 8,000 miles = $0.01 / mi
     $600 tire change / 60,000 miles = $0.01 / mi
     $1,186 average yearly repair / 16,000 average miles driven = $0.07 mile
That all adds up to $0.49 / mi and does NOT include insurance and DMV registration fees.

I'm not sure how you would implement this, since there's no way to provide a proof of deletion. Proof of storage is possible since you can do some operation on the stored data and then provide the result.

However, I assume when a file is "unpinned" in IPFS you stop earning Filecoin for storing it? I'm not sure but I can't imagine why it would be any other way.

It's not quite the same as screenshot testing, but I've had success using snapshot testing in React. The idea is outlined here: https://jestjs.io/docs/en/snapshot-testing

Snapshots of the intermediate representation (e.g. JSX in React) will be less brittle than e.g. a screenshot of pixels. It also works best when your UI is a function of some easily-constructed state. Other frameworks sharing these features would also work well with snapshot testing.

Pro tip: you can make any command into a real-time one with `watch`:

  watch bash -c "topngx < /path/to/access.log"
Will run `topngx` against access.log every two seconds and display the output.

Scoot | San Francisco, Barcelona, Santiago | ONSITE | Backend Engineer (Rails) | https://scoot.co

Scoot is making Electric Vehicles for Everyone. We hope to have a massive impact on global climate emissions by creating an urban mobility solution. In our first city of San Francisco, we launched a shared scooter network that has transformed the way tens of thousands of people get around the city. Having proven our model in San Francisco, our next phase will expand our service to new cities and new vehicles.

We have recently expanded to Barcelona, Spain and Santiago, Chile. Travel to our offices in these locations is encouraged! We are also open to hiring engineers based out of these locations.

Our stack is Ruby on Rails on the backend, React Native on the frontend.

We are looking to hire backend engineers to help build new tools for our riders, fleet technicians, and vehicle engineering team.

Contact jared at scoot dot co to apply.

🛵 Scoot | Senior iOS + React Native engineer | San Francisco, CA | Onsite

Scoot is building electric vehicles for everyone. We have been operating our fleet of electric mopeds in San Francisco since 2012. We just launched operations in Barcelona (our first expansion market outside of SF) and added electric bicycles to our fleet so it's a very exciting time to join!

We are looking for a senior iOS developer with React Native expertise. You will help implement new features for our riders in both San Francisco and Barcelona.

Contact jared@scoot.co for details. Come join us and be a part of the electric vehicle revolution!
