Why you might want a remote dev environment

Fearmongering aside — and Cthulhu knows there’s been a bunch, since this unfortunate tweet — there’s a bunch of reasons to want a remote dev environment.

Hi everyone. Has it been two months since I last posted something? Yes it has!

That seems like a nice round duration, so let’s break the silence with a few announcements.

I have a new website

If everything goes well, you’re on it right now.

Does it feel okay? Take a minute to accustom yourself to your new surroundings. Identify potential sources of fresh water. Gather some supplies with which to fashion a makeshift shelter.

Remember the snapshot we made allll the way back in Part 1? Now’s the time to use it.

Well, make sure you’ve committed and pushed all your changes, but when you’re ready, let’s go back in time to before we installed anything catscii-specific in our VM.

This should emulate the experience of a colleague onboarding onto the project well enough!

(I didn’t actually use VirtualBox’s snapshot feature for this, I actually set up a Ubuntu 22.10 VM on another computer entirely, but the effect should be much the same).

Our ping API is simple, but it’s also very limited:

pub fn ping(dest: ipv4::Addr) -> Result<(), String> // called as: ping(ipv4::Addr([8, 8, 8, 8])).unwrap();

It doesn’t allow specifying the TTL (time to live) of packets, it doesn’t allow specifying the timeout, it doesn’t let one specify the data to send along, and it doesn’t give us any kind of information on the reply.

Addressing the rumors

There have been rumors going around, in the Reddit thread for facet, my take on reflection in Rust, which happened a bit too early, but here we are, cat’s out of the bag, let’s talk about it!

Rumors that I, podcaster/youtuber fasterthanlime, want to kill serde, serialization / deserialization framework loved by many and which contributed greatly to Rust’s success, and I just wanted to address those rumors and say that…

I was not planning on doing anything specific this December, but a lot of folks around me (on Twitter, at work) have chosen this Advent of Code to pick up Rust, and I’ve got big FOMO energy, so, let’s see where this goes.

I’ll be doing all of these on Linux, so there may be some command-line tools involved, but don’t worry about them - the code itself should run on all platforms no problem.

Being creative is hard work, let’s go optimizing instead! My graphics engine dye was pretty naive about displaying text, and it was wasteful. Let’s see how I made it all better with this one weird tip.

Disclaimer: Even after a few years I’m still very much an OpenGL newbie. Please don’t hit me with crowbars.

Once upon a time, OpenGL was easy to use - and also falling out of relevancy as far as high-performance 3D graphics were concerned. But it wasn’t all bad! You could basically pick up any library out there and integrate it with your existing GL project. Not that it’s a good idea, but it usually just worked.

Background

I recently had a bit of impromptu disaster recovery, and it gave me a hunger for more! More downtime! More kubernetes manifest! More DNS! Ahhhh!

The plan was really simple. I love dedicated Hetzner servers with all my heart but they are not very fungible.

You have to wait entire minutes for a new dedicated server to be provisioned. Sometimes you pay a setup fee, et cetera. And at some point to server static websites and serve as a K3S server, it’s simply just too big, and approximately twice the price that I should pay.

Blog posts that praise Rust are many but funding is generally in short supply.

If even a small percentage of the money Rust saves companies was put back into the ecosystem it would help secure the future of the platform tremendously.

Multiple sources of funding

It is unreasonable going forward to expect the same handful of companies to provide all the funding.
