What's the best way to learn sales for a technical founder?

You're right, 8 bits is small enough to just store in a table.

This trick will work for any number of bits though. You might not want to use 2^64 entries in your table.

Thanks for your comment. Working on this now!

Hey there. I found that regression models do okay when the feature-set is simple. And I can see that deep learning seems like overkill but I found that it can create models that does justice to the complexity of real estate.

Hey Arubis, you're absolutely right. I copied the model from Scott (even the domain name). I'm unabashedly a huge fan and early subscriber of his newsletter since mid-2014.

Isn't this basically tumblr?

You're right, I updated it to reflect that it's paid. I think email address is implied by the newsletter though.

I'm obviously biased but I think the problems are fun and the solutions are valuable. Here are some blog posts I wrote that hopefully give you an idea of our questions:

Saved your comment, thanks very much! This was very helpful.

Edit: By the way, the tracker wasn't what.cd, was it?

Do you happen to know the name of the course? Very interested.

lawrencewu | 8 years ago | on: Ask HN: What are you hacking these holidays?

I'm working on better automation and alerts for my newsletter, Daily Coding Problem (https://dailycodingproblem.com/). Specifically, I set up a bot on Slack and now I want it to message each day's stats (emails sent, open rate, click rate) as well as notify on events (subscribe/unsubscribe, email).

I'm also working on a new landing page!

Oh god, thanks so much for this. I've literally just been testing on prod and praying that it works.

lawrencewu | 8 years ago | on: Ask HN: What coding challenge sites should I try next?

Sorry! There was a bug in the subscription logic. It should be fixed now. Mind trying again?

lawrencewu | 8 years ago | on: Ask HN: What weekend projects have you created?

https://www.juicebox.dj/ - Listen to YouTube/SoundCloud with others

Ended up taking way longer than a weekend but it's still basically a passion project of mine. I used Node.js, Firebase, and React.

lawrencewu | 8 years ago | on: Why I’m dumping Firebase for Web

Hey -- nice job! I have a question: is there a way to use MongoDB in the backend?

lawrencewu | 8 years ago | on: Ask HN: Projects that don't make you money but you're doing it out of sheer joy?

I created Juicebox, which lets you listen to youtube/soundcloud songs with other people: https://www.juicebox.dj/

I have made no money off of this. In fact, I've probably paid hundreds in hosting/domain fees. But I love what I've built so far and use it everyday with my friends. Please check it out, I'd love to hear any feedback!

lawrencewu | 8 years ago | on: Why I’m dumping Firebase for Web

Wow, this is the exact thing I've been thinking of writing, but so much better. I'm so glad this exists, brb trying it out right now

I agree with that. However, nothing is perfectly inelastic, and so increasing the minimum wage would still increase unemployment, even if only by a little amount.
