Thanks - just using Amazon SES to send the emails.

Yeah, it uses all airports within 40 miles of your location (or your closest airport).

Thank you. The front end is hosted with Netlify and the back end uses Chalice: https://github.com/aws/chalice It also uses Chrome Puppeteer for scraping. Chalice is super awesome. I'm planning to write a blog post

Thank you! I’ll take a look at the scroll bar issue.

That’s right, it uses the 90-day average price of flight + hotel. I take the z-score relative to that and filter for trips with lower z-scores.

Not currently — this is just for flight and hotel combinations. Good idea though, I want to add that along with train and boat trips.

Flying at higher altitudes in lower density air also reduces lift, though [1]. A plane does get extra benefit from flying higher as drag on the fuselage is reduced, but there is a limit — the plane has to go faster to make up for the reduct

Larger planes aren't significantly more fuel efficient. Look at the A380 vs. the 787. The reason airlines thought hub and spoke was more profitable was because they could basically guarantee that every flight would be full. If a flight

You clearly don't have a basic understanding of the issues here. Cars that use gas incur the additional penalty of environmental damage that is unaccounted for in the value of those vehicles relative to their cost. For example, a gas c

The government didn't say "give us the one we can make bombs with" or anything like that. In a review [1] they discuss groups working on thorium reactors who find that these reactors are potentially cheaper than water cooled

Why are you so in favor of nuclear energy startups when solar+batteries seems to be the cheaper and more immediately implementable option?

by gusgordon 11y ago
You would need to have huge amounts of batteries on the satellite, like 15 tons of lithium ion batteries per kg you want to get to orbit, or a nuclear reactor. Then you have the fun problem where if you miss the heat exchanger you have a de

Thank you! Websockets speed it up a little, about ~20-50 ms. I am a fan of open source, I would consider open sourcing part of the backend if I can turn it into a library that is useable.

Thank you! These are all great suggestions. I am probably just going to go down the line and add most of these. I want to stray away from user accounts because they take time and resources, but I'm not sure if that's the right cal

Thanks! I am pondering how I want to take this, but I want it to stay pretty lean because I like it more and it's faster to develop. I'll consider a dev blog, probably just in the form of a more comprehensive about page.

The percentage bar is % energy content. Maybe there is a way to make that more clear. Displaying things in terms of weight percentages is misleading because the body burns a set amount of calories, not a set amount of food.

Thanks for the suggestion. I agree, I think I could improve how details are displayed more effectively anyways.

Should be fixed now, thanks

Thanks, the trailing s is missing because it's trying to singularize "kaas" :) The information is from USDA, and scraped from a bunch of other various sources. The info should be vastly correct, "correctness" is als

Yes, I want to include that. There are a couple problems — incomplete nutrition profiles for certain foods, and slightly different foods having very different micronutrients (vitamins and minerals). For example, while a homemade cheeseburge

Thanks! I do plan on expanding it, not sure how yet. Right now, you can create a list and each list will have a unique URL. If you want to save a list, you can save the URL.
