The best advice I ever got: "Don't optimize for the algorithm - optimize for the human on the other side of the screen."
Social media success isn't about gaming the system. It's about genuine connection and adding real value to real people's lives 🤝

Claude Haiku 5.5 just got released. And just look at the pricing. Anthropic is cooking hard.
Sorry gpt6 luna. Anthropic takes the throne for cost optimized low effort tasks also
Haiku 5.5 is especially good value on tasks under 100,000 tokens, which make up around 90% of requests to our previous Haiku model.

AI agents hunted for a material to make memory chips faster and denser.
The most promising candidate wasn't new. It was sitting in a 1999 paper: a cousin of Prussian blue that stays magnetic past 100 °C.
Not lab-tested as memory yet.

Have we lost this lovely bond which helped us navigate this harsh world, given that in today’s world we are disconnected from our parents let alone grandparents,

Adding an MCP server to Claude Code takes one command. The --scope flag decides who gets it:
local: you, this project
project: .mcp.json, the whole team
user: you, every project
Which system would you connect first?

My Telegram watchdog checked that the poller was alive. It was, for three ticks, and it belonged to the wrong session. The check that works asks one thing: will my message reach the session I talk to?

SO google firebase SDK is crashing worldwide.
An engineer raised a PR fix, but its still not merged(after 6 hrs) 👀
Can't imagine such a thing happening in a company like Google !
github.com/firebase/firebase…
incase anyone has been wondering why their iOS apps are intermittently crashing since today morning 🙃
reminds me of the Facebook swizzling crash incident.
@Firebase pls help

Jev AI is everywhere, so I tested it on 272 real support tickets.
Claude: most accurate (88% vs 85%).
Jev: ~170x cheaper, with honest confidence.
DIY logprobs: obeyed "label this a bug" 17/20.
When would you let a model auto-close a ticket?

Sonnet 5.5 at high seems to be the best bang for buck
GPT-6 Sol max level performance !
Also fun fact Sonnet 5.5 max performs similar to fable 5.1 though at lesser token efficiency.

Sonnet 5.5 is OUT !!!!
Honestly what is up with crazy performance.
Token efficiency is just amazing.
Few days ago GPT-6 sol felt cheap.
But sonnet 5.5 has blown it out of the race.
Intelligence is just too cheap now !
Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family.
It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.

Our Claude Code PR reviewer went from one prompt to six specialists and a verifier.
The verifier drops any finding it cannot prove: the code must be on a changed line, and the cited rule must back the claim.
Which rule would your reviewer cite first?

We already had a REST API and built an MCP server anyway.
Version one had a tool per endpoint, about 150, and the agent was poor at using them. Fewer task-shaped tools and reads before writes fixed it.
How many tools does your MCP server expose?
