@bertspaan Very cool! The colour scheme is great and it's all very smooth.

the most underrated hire right now is a great product person.

when i say product person i'm def not talking about a product manager. perhaps i think there has to be somewhat of a new role. i don't have a good name for it yet but maybe something like "product thinker".. someone with an intuitive grasp of the product as it exists, where it's soft, where it sings, & how to iterate it toward something even sharper. in some sense, this person has to cohesively hold in their head where this product should be 2 years from now & work backwards from that.

i say this cuz when building was hard, engineering was the bottleneck & the status hierarchy often reflected that. building is no longer hard. which means the variance in outcomes has shifted almost entirely to judgment on what to build, how to sequence it, & how to talk about it.

& the story matters as much as the thing. internally, it organizes the team around a shared model of why. externally, it shapes the interpretive frame users bring to their first experience. you can't retrofit narrative onto a product & expect it to land, it has to be load bearing from the start.

the rarest version of this person sits at the intersection of culture & deep technology. someone genuinely bilingual. they know what's technically possible & they know which cultural currents are real vs. ephemeral. that combo is what separates products that feel inevitable from products that feel assembled.

before ppl clap back with this person has always been valuable, i know.. i am just saying now they might be the most *important* person in the room. their value compounds like never before.

Released today: /loop

/loop is a powerful new way to schedule recurring tasks, for up to 3 days at a time

eg. “/loop babysit all my PRs. Auto-fix build issues and when comments come in, use a worktree agent to fix them”

eg. “/loop every morning use the Slack MCP to give me a summary of top posts I was tagged in”

Let us know what you think!

Skills are among the most consequential new tools for AI, and Anthropic just released a very impressive nontechnical Cowork Skill that builds Skills, including doing interviews & providing benchmarks.

I think you still need to add the human touch, but this is a big leap forward

Whilst the broader idea has been on my mind for years (bought the domain in January 2013!), this wouldn't have come together without the latest developments in AI. Started just after Christmas, and got the final bits of inspiration on flow from lovely new bookmarking tools such as @brian_lovin's https://t.co/aMynVn5P2s and @ephraimduncan's https://t.co/11wfmDXS5M. That improved the user flows and capturing approach a lot. Now there's a ton more I'd like to add, but in it's current state works well enough for the primary use case of organsing travel research and inspiration.

I'm excited to share one of the projects I've been building this year: Epic Itineraries.

I built it for myself first. I'm the kind of traveller who spends hours online researching, reads every restaurant review, digs up the off-the-beaten-track spots, and treats the pre-planning phase as part of the adventure. Epic Itineraries is a bookmark app on steroids, for travel. Save links from anywhere, manage them in collections, and create tailored itineraries based on your finds. I'm using it for our summer holidays to France and a city trip to Rome in autumn. I also backtracked scattered links and scribbles from our epic adventure to Peru last year. The app is now my one source for all travel findings and research, and develops as I encounter limitations or get new "this would be cool" ideas.

It's also a proper playground of all sorts: URL fetching, evaluating AI models for itinerary generation based on saved links, building a ChatGPT app, developing an MCP server, launching browser extensions, verification. Lots of firsts. Lots of trial and error and repeat.

And whilst writing code has indeed become much easier, hooking it all up is still quite the grind.

Collect inspiration, generate adventure.
Your itinerary is as good as the research you put into it. I think that's exactly how it should be.

If you’re the kind of person who spends hours digging up the best places to eat and the best activities to do, then gets lost between 27 tabs and still got no proper plan — this could work for you too. Try it out → https://t.co/BQuaxtsuK9

@blwiertz Very nice. Registered!

[Edwin van Leeuwen @evanle]

Hahaha the README is golden, nice ;)

Going to try this out, I've been manually switching terminal tabs to achieve the same, and share the experience of the models complementing each other.

"Key takeaways from the synthesis:
- 10 overlapping findings — high confidence, independently confirmed by both reviewers
- 2 severity disagreements resolved: cross-PTO test mutation escalated to P0, silent weighting clamp to P1
- 27 findings unique to Report A (broader multi-agent coverage), 0 unique to Report B (all 10 were covered by A)
- Consolidated total: 4 P0, 18 P1, 17 P2 (39 unique findings)
Report B's value was in severity precision — it correctly flagged the cross-PTO mutation as P0 where the multi-agent audit had it at P1."

@bnj @variantui This looks golden, very well done on the video. This fits how my brain works, excited to test this.

Oh, somebody's watchin' me (oh, it keeps on trying me)
Anxiety, anxiet-, oh, I feel anxiety (it keeps on trying, t-trying, trying, oh)
My anxiety, it's my anxiety, can't shake it off of me

Weekly reviews never stuck for me until I turned them into an ongoing conversation. Combining Claude Code with @rickpastoor's GRIP templates and acces to previous entries, I now get new and engaging questions each week that I answer using @WisprFlow. #NewYearResolutions
