xkcd: Gravity is now live!This was a really fun one to hack on. Back when we made a previous exploration game comic, we gave the character a hoverboard to skip animating a walk cycle.For this one, I was getting frustrated thinking about handling collision edge cases, so I asked Randall and davean if we could give the ship an unbreakable circular shield. That made life soooo much easier š¤£https://xkcd.com/2712

@pixel It cuts the other way though. A few months ago I inundated my moonlander with beer because I want used to as tall of a glass being in my arm space. š

Yesterday morning, I pulled open my laptop to send a quick email. It had a frozen black screen, so I rebooted it, andā¦ oh crap.My 2-year-old SSD had unceremoniously died.This was a gut punch, but I had an ace in the hole. I'm typing this from my restored system on a brand new drive.In total, I lost about 10 minutes of data. Here's how. (Spoilers: #zfs #zrepl)

I donāt back up my drives, I replicate them.Last winter, I set up my first serious home network storage. Part of this project was setting up periodic backups of the computers I do creative work on. After surveying the options, one approach stood out: ZFS incremental replication.One of the flagship features of ZFS is the ability to take efficient point-in-time snapshots while itās running. You can then send only the changed data to other machines...

To automate taking snapshots and sending them to my NAS, Iām using a really cool piece of software called zrepl (by @problame). I configured it to snapshot and send my entire filesystem every 10 minutes.Since the snapshots are incremental, this is fine to run in the background on my home network to keep the replica up to date. The last run took 14 seconds to transfer and sent about 64 MiB.

@problame Restoring the system was a learning process, and unfortunately quite manual. I let the 625 GiB ZFS receive operation run overnight.My snapshots are encrypted by the original computer (this is cool because the NAS canāt read them!). So I also needed to restore the encryption āwrapper keyā to be able to use the backups.Not gonna lie, it was pretty terrifying until I had my first confirmation I could decrypt the data.

@problame To rebuild my system, I followed the OpenZFS guide for setting up a filesystem from scratch via Ubuntu 22.04 live USB:https://openzfs.github.io/openzfs-docs/Getting%20Started/Ubuntu/Ubuntu%2022.04%20Root%20on%20ZFS.html#step-4-system-configurationThis was a priceless resource for getting back up and running. Itād intimidated me in the past, but itās *so* thorough, and I learned a ton going through the process. This is the best hand-on guide Iāve seen for modern partitioning and chrooting in a Debian environment.

@problame The end result was a beautiful moment: my laptop booted back up to right where Iād left it. Even my browser tabs restored my unfinished work from the previous night.Thereās this classic series of Chromebook ads from 12 years ago where computers are repeatedly destroyed in elaborate ways, and the host picks up a new machine and picks up where they left off, with no data lost:https://www.youtube.com/watch?v=lm-Vnx58UYo

That ad has been in my imagination for over a decade. I finally achieved my dream of having a similar disaster recovery plan. And it worked!Setting ZFS up initially had a really high starting cost: it took a full filesystem swap. Maintaining it takes fairly knowledge-heavy and manual processes. But it certainly has unique benefits.This is the first time I can recall losing an SSD in over 15 years of using them. It was fantastic luck that Iād set up replication before my first one failed. š

Btw, if youāre curious, the offending drive was a WD_BLACK SN850 from my original Framework order. Iād heard unsettling stories on the Framework forums of this drive spontaneously dying or becoming unbootable. I guess it was my turn to roll some unlucky numbers.Amazon shipped me a new SK Hynix P41 SSD and a Sabrent NVMe enclosure in about 3 hours yesterday, which was phenomenal. I usually try not to order tech from there if I can avoid it, but credit where creditās due.

@matrix This seems like a reasonable way for Element to continue to sustainably fund development. The CLA gives Element unique power to sell exemptions from the AGPL copyleft requirements for these projects. If Element uses this privilege to grow Matrix as a whole, it seems like a win overall.

I've been on a quest to find the perfect sleep mask, so I wrote a guide about what I've learned. No sponsors or affiliate links, just design thoughts and hot takes I needed to get off my chest. Hope it's useful to someone!https://chromakode.com/post/sleep-masks/

@ilovecomputers Thanks! @konahart and I did a fun little photo shoot to get those. I wanted to be able to see where each mask rides in the context of eyes & nose š
