New top story on Hacker News: Ask HN: Should grapefruit juice have warning labels for medicine interactions?
Ask HN: Should grapefruit juice have warning labels for medicine interactions?
18 by acadapter | 11 comments on Hacker News.
I recently saw a short documentary with a case where someone had an overdose because of interaction with medicines and grapefruit juice. This is apparently due to substances in grapefruit that interact with an enzyme used to metabolize some medicines. Warning labels in the leaflet seems like a very inefficient solution. Why isn't the warning placed on products containing grapefruit?

Who acquires big (13,000 lines) Mac apps?

I don't want to deal with Apple any longer. My app helps college students in academic trouble organize and sustain large academic projects. It's mostly for very bright college students with ADHD. Any potential acquirers you would like to suggest?

I've published the sources for the code generation and the code that was generated on GitHub: https://ift.tt/MPILJKG I've been experimenting with merging prompts together, with a goal to write the full backend in a single prompt. On the form: > 1. Setup a flask web server > 2. Add a /add endpoint It works reasonably well, but it seems like it's loosing some precision in the prompts... The person that coined the term "prompt engineering" was right, it's really important to learn what words to use to get the AI to do exactly what you want it to do.

New top story on Hacker News: Ask HN: How to price a service that saves hundreds of engineering hours?
Ask HN: How to price a service that saves hundreds of engineering hours?

I've built a Cypress test runner that completes all tests (no matter how many you've got) in less than a minute. In contrast, based on my experience, a medium-size Cypress test suite takes about 15 minutes to complete. The only catch is that individual tests have to be under 30 seconds. The idea came out of frustration running Cypress in my previous company, where it was taking 10 minutes+ to run all Cypress tests while parallelizing across 30 VMs and costing us in excess of USD 2k/month. In order to achieve this, I have effectively built a new Cypress test runner from the ground up. It understands Cypress syntax, but otherwise have nothing in common with how Cypress works. The way it achieves this performance is by splitting each spec into individual tests and starting all of the tests at once, i.e. if you have 10 specs with 5 tests each, this program will start 50 VMs to run your tests. I have two companies trialing this at the moment and the feedback has been incredibly positive, saying that it is saving _hundreds_ of engineering hours. I am trying to establish how to price this. The challenge is that this model is profitable at scale, but losing money if there is not high density of clients. This is because it costs me USD ~0.15 to run a VM for 1 hour and I need to spin up enough VMs to complete all tests, and I am charged in increments of an hour. My thinking is to charge 2 cents per a test-minute, i.e. Using previous example of 10 specs with 5 tests each, it would cost USD 1 to run all tests once. If you run integration tests 100 times per day, that's USD 100/day. This may sound much. However, if prior to using this you were waiting 15 minutes to run all tests, that is 14 minutes saved. If avg. engineer in your company is earning USD 60/hour, you are saving USD 14 by having engineers get immediate results rather than waiting for them. If positioned that way, it doesn't sound expensive. I am currently targeting companies with 30-50 engineers (existing customers are series A and series B companies). At this size, they don't have crazy amount of tests, so I can deliver on the 1 minute promise, and they care a lot about moving fast. What sounds reasonable?
