Author here.

I've spent the last six months replicating the paper "Champion-level drone racing using deep reinforcement learning" and now I'm writing down the blog posts I wish I had along the way.

Any feedback is welcome, especially as I'm a bit unsure if I struck the right balance between being concise and not requiring too many prerequisites.

Also if you're working on RL and robotics (especially aerial), let's connect!

Thanks!

Ask HN: How to release research paper code?

How would you publicly release code from a recently published paper? I have some python notebooks and would like to present them as a library. Should I use docker? Pipenv? Poetry?

Interesting question, from my understanding Pathfinder is only concerned with rendering so it doesn't completely replace FreeType: you still need some software to extract the curves path data from the font file. This can be done in rust with skribo and font-kit

You can check out this issue for more info: https://github.com/servo/pathfinder/issues/143

Absolutely, Subpixel AA, Kerning, Ligatures, Gamma Blending, and Emojis will be treated

Thanks :) I've used what was available on the latest ubuntu lts. FreeType functions return 0 (FT_Err_Ok) on success or a specific value for each function, but yes I agree that error handling could be better, maybe at the expense of terseness.

I agree that it's an interesting topic. On reddit one of the authors of dear imgui has some interesting thought on it: https://www.reddit.com/r/programming/comments/cfxltf/modern_...

Looks like something I did some time ago[0], nice to see that this space is being explored. Wikum[1] from MIT's CSAIL is also an interesting alternative.

Ask HN: Should I join a startup or do open source work to get an internship?

daww — Fri, 06 Apr 2018 21:07:17 +0000

Hi, I am currently a first year software engineering student (in an Italian university) and I would love to get an internship at one of the big fives next summer (2019).

After doing a bit of research I've figured that since so many people apply I need to do something to get noticed among the competition.

I have found two ways to do so: contributing to an open source project from one of those companies or joining a new startup created by ex-students of my school.

Which one do you believe that it would be a better time investment? The startup has a cool idea but since it is a startup provably it will not take off.

In both cases it will be free work, one in form of open source contributions the other in writing a nodejs backend.

Which one would look better on a CV?

Do you believe that the open source work could lead to some kind of referral from someone inside the company and give me better luck in getting the internship?

Thanks in advance
