If (once again) people of colour being first on the chopping block on UK Traitors isn’t the perfect illustration of baked-in societal racism then I don’t know what is. Literally every time.

I’ll be otherwise occupied for the next while hanging out with my new bestie. See you on the other side.

@freeagentapp.bsky.social is your onboarding flow broken? I can't see any way to "complete" the last two items. No matter how many times I follow those two top links, the actions remain and the flying start banner persists.

As much as Act 3 is occasionally kicking my ass, Hollow Knight Silksong is easily the most fun I’ve had playing a video game in a long time. So much character, inventiveness and attention to detail wrapped up in wonderfully balanced gameplay mechanics.

once you’ve compiled Ruby you just need to download RubyGems from rubyforge.org to get started.

show this to anyone else you know who also assumed DHH was just a normal conservative dude rather than a raging white supremacist lunatic
DHH Is Way Worse Than I Thought | jakelazaroff.com
DHH's politics are not normal. Maybe they used to be, I don't know, but as of right now the dude is_way outside of what most people would consider moral or acceptable.

I've heard the argument that because his behaviour is fine in Ruby spaces/events, then it's all good, but that to me is disingenuous to say the least when it's very clear from his posting just how he feels about large sections of the community.

I have a growing number of unpurchasabels on my shopping list because Siri doesn’t understand me saying “puy lentils”. Alongside “toilet sauce” we now also have “foil lettuce”.

@rhiannon.io 's entire thread here, honestly. Ruby Central lost the plot here and has made a lot of bad calls, but hopefully this can serve as a catalyst to restoring it to what it should be.

Brandon is right. Ruby Central needs broader funding to avoid even more consolidation of power in the Ruby ecosystem. I for one am committing to do my part.
RE: Ruby Central funding, and a consolidation of power with companies like Shopify.
For years now the lead funder of Ruby and Rails initiatives has been Shopify, full stop. They've contributed heavily in both time and money, and through that have left a substantial impact on Ruby and Rails.

Maybe I lucked out but made it out into the coral chamber pretty quickly. Either that or playing the same runback to Last Judge for hours over and over helped me finally learn how to control Hornet properly

Ah I went straight in (and down) from Last Judge. So far pretty brutal, but perhaps I dodged a bullet not backtracking?
