Concise explanation of the consumer experience in the 2020s. It's analogous to how the internet is different for everyone these days.
conorsen.bsky.social Conor Sen @conorsen.bsky.social · 1d
The whole recent dynamic of consumer-facing businesses that exist due to capturing a large % of rich consumer spending and then offer some capacity and a worse experience to non-rich consumers leads to a lot of societal tension.

i think one of my hotter takes is that we don’t need a bigger LLM context for continual learning, we just need better recall over the context we have

subagents = stack
files = heap

we got gobs of context space already

2025 is now, officially, the worst year for job creation outside of recession since 2003.

One of the major uses of Claude Code is to build Claude Code and to create a bunch of skills and tools and config for Claude Code. It is a tool that is constantly being used to improve and extend itself.

This makes it a type of emacs.

lol when boston traded doug mirabelli, realized that no one else could catch wakefield’s knuckler, traded back for him a few months later and rushed him to the game with a police escort, was truly a great moment for Sports

The "Coverage Sack" was a myth in 2025.

Forcing the QB to hold the ball longer actually led to WORSE defensive results.

When QBs held past 2.9 seconds, the defense wasn't winning with coverage—they lost to the scramble drill.

If the jets aren’t gonna play any semblance of respectable defense, then I say punish them. Hang 8 touchdowns on them and force your division rival to sit with that in the record books for all time.

No mercy. Pats aren’t winning the Super Bowl anyway. Make this count.

Man, I really hope the Patriots are aware of the obscure NFL rule that says a quarterback automatically wins MVP if he throws eight touchdowns in a game

Lily is my marketing friend at work

she single-handedly convinced me that the future is in tools like Claude Code

the future is going to be disrupted by high agency people who just want to hack, no longer constrained to people who know how to code

Lily Luo • • 1st Marketing Operations Leader | Al Automation & Orche... 4m • G As we head into the new year, I've been reflecting on what changed for me in 2025. I used to think Marketing Operations was about buying the right tools and stitching them together. Data problem? Buy a data tool. Need account research? Ask the rep to spend two hours Googling and summarizing in a slide deck. This year, that mental model broke. The scale of what we needed: 1:1 ads for thousands of accounts, executive research briefings, content at scale, wasn't something I could buy off the shelf. So I started building with Al. After seven months of experimentation, l've shipped systems now running in production: over 1,000 automated account research reports, a Python-based engine for personalized ad copy, and workflow automation that replaced hours of weekly "Excel Hell" with one click. But all of those tools share a limitation: they're stateless. They run, produce an output, and forget everything. Over the past couple of weeks, I've been exploring something different, inspired by a brilliant colleague (Tim Kellogg, who built his own ultra-sophisticated agent l've modeled off of): Al that maintains memory and context over time. I started building an autonomous agent called Atlas that wakes itself up every two hours, progresses projects in its backlog, and can even modify its own code based on research it conducts.

Andrej Karpathy is worried about keeping up with software engineering practices
Andrej Karpathy @karpathy X.com l've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.

I was prepared for Xmas with plenty of AA batteries, and all the toys for the kids required AAAs instead. I've raided every remote in the house to try to cover up the mistake.

Contact import has always been the most effective way to find people you know on a social app, but it's also been poorly implemented or abused by platforms. We weren't willing to accept that risk, so we developed a fundamentally more secure approach that protects your data.
bsky.app Bluesky @bsky.app · 25d
v1.112 is live!

We’re launching Find Friends, a contact import feature that helps you find people you know on Bluesky.

Try it! In the mobile app, go to Settings → Find friends from contacts.

Read how we took a more secure approach to this than other platforms: bsky.social/about/blog/1...

Meanwhile, over on the other site:

> …someone who is developing an end-to-end encrypted messenger platform MAY unwittingly be considered a hostile actor against the UK?

To be confirmed:

assets.publishing.service.gov.uk/media/69411a...

x.com/AlecMuffett/...

#encryption
6.17. Since hostile activity does not require any knowledge or tasking by a foreign state430, the phenomenon of double-ignorance could arise. A person may be engaged in hostile activity if they do something which, unknown to them threatens, national security and which is in the interests of another State, also entirely in the dark. For example: The developer of an app, whose selling point is end-to-end encryption which would make it more difficult for UK security and intelligence agencies to monitor communications. It is a reasonable assumption that this would be in the interests of a foreign state even if though the foreign state has never contemplated this potential advantage.
