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.

He makes $200k / year from his newsletter: http://www.niemanlab.org/reading/ben-thompsons-stratechery-i...

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:

Given a table of currency exchange rates, determine whether there is a possible arbitrage: https://dailycodingproblem.com/blog/2018/01/02/find-an-arbit...

I run a (paid) newsletter that sends fun coding interview puzzles every day. If you're interviewing around (or if you just enjoy programming problems), check out Daily Coding Problem: https://dailycodingproblem.com/!

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.

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.

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

I'm the founder of Daily Coding Problem (https://dailycodingproblem.com/).

We send high quality programming questions every day. You can sign up to our mailing list for free to get problems starting tomorrow at 9AM PST.

I hope you enjoy our problems!

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.

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

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!

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.

Yup!

It also doesn't mean a decrease in unemployment, which is what this report claims. I'm also still unclear on _how_ a minimum wage would have no effect on unemployment, which is what the law of supply and demand predicts.

- Raise the minimum wage

If we raise the minimum wage, that would surely increase unemployment. Even a minimum wage job is hard to get for an uneducated, unskilled person, so how would it be easier for them to get a job at a rate employers are even less willing to pay?

Easy to say, hard to do. We don't like change. Change means possible danger, it means relinquishing opportunities, it means no safety net.

Part of the happiness that comes from a new relationship comes from not just discovering new things about each other (or NRE, or the Coolidge effect) but from the (misplaced) belief that things will go on this way forever. Embracing change means sacrificing that pleasure, which you might be able to do if you possess foresight/discipline, but it is hard and not obvious, especially when you have an of love that's foolish, us-against-the-world that reinforces that mentality.

Nice playlist!

Shameless plug, but you can also check out a collection of my favorite songs on my Juicebox: http://www.juicebox.dj/lawrence

It's mostly hip-hop, deep house, and experimental music.

I don't know why you are getting downvoted because you're absolutely right. The first three markets named (airlines, telecommunications, health care) are all heavily regulated and the barrier to entries are controlled by the government, not natural market forces.

Monopolies are not all bad. Sometimes a company has a monopoly because they just offer a better product (Amazon, Google) and they shouldn't be punished for that, especially when there's no government intervention that exists to protect them.

I don't think this is a good solution. Where is the incentive for anyone to maintain properties anymore?

"Owners of valuable land would be forced to make maximum use of land with higher density rentals in order to make sufficient rental income to pay the land tax."

I don't see how this follows if all income is taxed at 100%.

The correct solution is to eliminate NIMBYism by eliminating the ability for homeowners to restrict the construction of new buildings so that new housing can be built. Rent control should also be eliminated, allowing demand to match supply.

It rubs me the wrong way too. But rationally, it's just your classic price discrimination tactics (coupons and special discounts) on steroids, so if you aren't upset by those, you shouldn't be upset by this.

I guess my main issue here is the clickbaity title, since I don't think Amazon is making us suckers. The consumer ultimately has the upper hand since they can just choose not to purchase the product, or use a price search engine to find a better deal (which is akin to using a coupon - people that are price-sensitive are more willing to put in effort to save money).

So is it unfair when someone uses a coupon they found in a flyer? They're not paying the same price for the same item as someone without a coupon, and people using coupons are likely to be less affluent.

And what about student discounts? Is it unfair that students get better deals on Photoshop and Microsoft Office?

This article paints a pretty good description of how price discrimination is used in online shopping and how places like Amazon try to extract consumer surplus. I don't know if I agree with the title's claim, though. If a product is shown at a higher place and you click buy, you're still choosing to buy the product at an accepted price, i.e. the value of the product is still worth more than what you're willing to spend, otherwise you wouldn't have bought it at all. How does that make you a sucker? Because someone else might be getting it for cheaper? That might seem unfair at first, but ultimately it's irrelevant. Other people have different opportunities for a lot of things. Complaining about what price someone is voluntarily willing to pay for a good is probably near the bottom of my list of injustices.
