It might be more efficient (and effective) for the filtering to happen closest to where the water is drank. If it happens at the treatment plant, then you end up filtering lots of water that is used to water lawns, shower, etc. Only a small percentage is used for drinking.


I don't think it's good to have toxins on our lawns (where our pets roll around) or in our shower water either though?


This is correct. Pollution absorption though the shower is a thing


Agree, you also need chlorine in the water to treat the distribution system of pipes to your home. So you need to filter chlorine at point of use anyways.


Square | Back-end or Full-stack Software Engineer | REMOTE (US and Canada) | Full-time

Apply to join the Channels & Fulfillment team at Square. We are helping many traditionally in-person sellers succeed with moving parts of their businesses online. The two forms this is taking right now:

- Make it ridiculously easy to list your products across many channels/marketplaces (e.g. have your product start appearing in the Google Shopping search tab)

- Expand Square's common fulfillment APIs to simplify the "behind the scenes" operational part of what happens after they receive orders and need to execute on these contracts

We're already seeing a lot of success, and it's been really rewarding to help these businesses. This is a massive project, and most of work is in a new Go / Golang codebase hosted with the help of Redis, Kubernetes, and AWS.

Note that the job post says "Canada" but we're open to folks in both Canada and US for this remote position. Please start your message with "[HN]" when you apply. Feel free to send any questions in comments. https://smrtr.io/4RcLd


Square | Front-end or Full-stack Software Engineer | REMOTE (US and Canada) | Full-time

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Many teams are hiring at Square, but I am the hiring manager for the Channels and Fulfillment team. Note that the job post says "Canada" but we're open to folks in both Canada and US for this remote position. Please start your message with "[HN]" when you apply. Please send any questions in comments.

Tech we use: Go/Golang, Ember, React, Redis, AWS, Kubernetes


Is Square hiring SWEs with < 2 years of experience right now?


"Now you can code" means "Now that you've done this preemptive thinking, you can start coding the function."

It definitely was NOT written to imply you are a certified software engineer now : )


It's amazing for anyone learning to code. I run my coding school's classes off of Replit Classroom.

What if there were humanities bootcamps?

That probably sounds like a joke...but why should a traditional expensive university be the only structured way to get exposure to broader human knowledge?

An intensive bootcamp model doesn’t actually make sense for breadth (they are designed for the opposite)...but if you told me I could be part of a structured organization in my city where I’d be introduced to interesting broad humanities topics through lectures from experts and assignments over several months then I’d be interested.



But would you be 5 months off of work and $15,000 interested?


If the answer is 'no', we have to ask why people are "4 years off work, 100k+ interested"?

There is a value to history, the arts, humanities. But that value isn't always well captured by our current society.

Optimization systems (like our economy) optimize for what I'd easy to measure, and ignore what's hard. A lot of those fields accrue value to the commons, which is value which is hard to measure, as a result their dollar reward is often lower than the value they produce.

There isn't an easy solution - and often when faced with hard problems the answer taken is fall back to the tools were used to using to measure.


How on Earth does it cost $450,000 to teach humanities to a class of thirty adult students for five months?


I was just taking the costs from most tech boot camps.

When I first invested in Bitcoin several years back, I tried to imagine ways that it could one day be deterred from becoming increasingly adopted and valuable. Government regulation and hacking were obvious possibilities, but I never considered “death by fragmentation” at the time. I think Bitcoin would be a lot more valuable today if it had not been for the explosion of largely greed-motivated shitcoins (and later ICOs) entering the market.


It was the scalability problem that killed Bitcoin and it probably would have happened a lot sooner without the fragmentation.
