Thanks for writing this, Jessica.

This is a great paragraph:

> If you want to, you can just decide to shift gears at this point, and no one's going to tell you you can't. You can just decide to be more curious, or more responsible, or more energetic, and no one's going to go look up your college grades and say, "Hey, wait a minute, this person's supposed to be a slacker."

I've often seen people get too attached to an unproductive "identity" instead of looking at things as they are. It's way too common for people to fail once and think they're a failure, rather than thinking that they just failed at that particular time.

By the way, I remember meeting you during the S23 batch and how genuinely excited you were to meet us, young founders who were just getting started. It does seem like you found your people!

I know this is repeated ad nauseam by now, but as an ardent user of em dashes for many years pre-LLM, I think this a bad heuristic.

Co-author and founder of Briefer here.

I used to use em dashes before they were cool. I actually learned about them when I emailed a guy who's a software engineer at Genius and also writes for The New Yorker and The Atlantic.

I asked him for tips on how to write well and he recommended that I read Steven Pinker's "The Sense of Style", which uses em dashes exhaustively, and explains when and why one should use them.

It also pains me that I can't use them anymore or else people will think an AI did the writing.

We've tested almost every visualization library under the sun when building Briefer (https://briefer.cloud) and I can confidently say that Apache ECharts is the best.

The main issues with other libraries is that they're either:

(a) ugly (b) difficult to use (i.e. having to do things imperatively) (c) not flexible enough

Apache ECharts solve these 3 problems. It's pretty by default, it allows us to mount/calculate the declarative spec for the graphs in the back-end and then only send the desired spec to the front-end so it can render, and it's also extremely flexible to the point we can support everything that traditional BI tools can do.

We've never had to extend the lib to do anything new, everything we need is already there.

Glad to see this great piece of work on top of HN.

lucasfcosta commented on Money lessons without money: The financial literacy fallacy   anandsanwal.me/financial-... · Posted by u/herbertl

Most people’s money problems would be solved if we taught them not to chase status instead of focusing on the numbers.

Financial literacy itself is quite simple: spend less than you make.

Everything else is an optimization and it’s pretty easy to learn with a few days of research.

I know this is the classical HackerNews type comment, but I honestly can’t understand why it’s so hard when there’s so much information available and so few pre-requisites (almost none) to learn about it.

I love this idea so much.

Lan parties were probably the best part of my teenage years.

Also, the terrace part is amazing.

I miss the good old days of playing DotA (the old one) the whole night while drinking coke and eating pizza with friends.
