Doing the work of evaling my badass GitHub Actions skill then tweaking, then eval, then tweak, ♾ to prove that my skill works even on Haiku, which is the shittiest of all the models now

Which is more active and more authentic at #kubecon, X or Bluesky? I asked Claude for analysis of last two days. Across both, 2/3rd of posts are corporate accounts or humans promoting, with 1/3rd being genuine experiences and shared learnings. X has more posts, but Bluesky has more "real humans"
Stats of posts and people posting them on X and Bluesky for KubeCone, with this summary text underneath the stats: Verdict: X Has More Volume, but Bluesky Has More Authentic Voices
X has more raw posts (~260 vs ~190), driven heavily by corporate and bot accounts. The percentages are actually similar across both platforms — about 64–67% of posts on both are some form of marketing or corporate presence.
However the unique human voices in Category 3 tell a starker story: Bluesky had ~54 distinct humans just sharing their experience, while X had only ~32. Bluesky's Category 3 is qualitatively richer — more humor, personal observations, reactions to talks, community moments. X's Category 3 is thinner and more diluted by news-summarizer accounts and amplification bots.
One notable X-specific pattern: about 14+ near-identical tweets from different human-looking accounts all sharing the exact same Broadcom press release within hours of each other — coordinated PR amplification that has no real equivalent on the Bluesky feed.
So yes — your hypothesis holds on X too. But the ratio of authentic-to-promotional is actually slightly better on Bluesky, and the humans posting there are doing so with noticeably more personality.

My bank can't keep statements after a year, but Amazon still remembers what I purchased in 2000, including this banger. Only 1.8 stars? They must have hated the ending.

What's your wildcard localhost domain for dev? I use *.bret.lol and you're welcome to use it too. I've used many over the decades for localhost DNS resolution (without editing /etc/hosts) but many have shutdown so I made my own years ago and it costs $20/yr at cloudflare. Here's how you set one up:

With so much AI fan fiction showing up, I have a friend who keeps taking the bait, so I'm thinking of starting a campaign to convince him that Obi-Wan had a son and that Disney bought Mattel

TIL that AI prefers blue, purple, and pink, which I'm fine with since they are my favorite colors. @bethfish.bsky.social pointed out recently that when you search Canva for AI templates, they are mostly the same colors... across hundreds of designs!

Tried using Cursor to build a swift macOS app tonight (with only xcode cli tools installed) and it gave up after many failed builds and blamed my mac. Then tried to update system and prompted me to sudo rm system tools. Maybe enabling the YOLO setting to let it do things w/o approval was a bad idea

I only recently learned that certain hats styles fit certain heads better. I evidently don't look good in the small curved "dad hats" 🧢 that that I've been wearing since a kid. I'm now trying out the flat brim hats.

Can I just say how great AppleCare+ is... a month-old iPhone 16 and I dropped it 2 feet to a plastic chair and shattered the back glass. I immediately submitted a support case through the app and chose the "ship me a replacement" option. Overnighted to me and 24 hours later I'm setup on a new one
