does anyone who is visually impaired or otherwise rely on screen readers have any experience with trying to use linux ?
from what i can tell the linux experience seems pretty hostile to screen readers, and there's not very much resources dedicated to orca, which seems to be the main implementation .
please share your experiences with me if you can, i want to try to make things better .

This wall was opened up 2 years ago to fix a wiring problem. Jay and I finally closed it back up today.
Whoops. Even a Snap-on 3/8" drive 12" breaker bar isn't gonna hold up to being used where a 1/2" drive 36" breaker bar should be used. Guess I need to buy both now. 😬
You see a corgi puppy. I smell a chemical warfare delivery system.

In the spirit of NFTs, I propose UnsafeCoin. Mining is a side effect of compiling Rust code. Coins may be used to buy indulgences that allow you to use the unsafe keyword. Each indulgence generates an NFT to commemorate the event. I will not be taking questions at this time.
Line trimmer has a compatible, but not OEM, carburetor. Worked on it for an hour before realizing high and low speed adjust are reversed from OEM. 🤦
Preparing for winter with a new wood rack built from scraps. Trips to the wood shed should be much less frequent.
Found a really good deal on Akro-Mils bins on Craigslist. Finally sorted my common cables.
NXP has updated a few LPC55S69 documents since our DEFCON talk. Spreadsheet attachment removed from UM11126. AN12868 changed "hidden coprocessor" to "dedicated processor." Still no public notification of CVE-2021-31531. Feels more like a coverup than an disclosure.
