"Summarize from here" in Claude Code is awesome:
Here is how it works:
1. Hit Esc+Esc or type /rewind. This will open the checkpoint menu with a scrollable list of all checkpoints Claude has created during the session.
2. Pick the checkpoint you want to summarize from. Everything before this checkpoint stays intact, and everything after it will get compressed.
3. When you select the checkpoint, you'll see the "Summarize from here" option. This is the one you need to select.
Claude will collapse all messages from that checkpoint forward into a compact summary. The conversation history before the checkpoint will stay exactly as it was.
This is what you want to do after a long session where you worked on specs, architectural decisions, and constraints, but Claude went on a debugging detour and started installing a library, or did something else that added a lot of garbage to the context.
If you run /compact, you'll be summarizing the entire context, and you don't want that.
Instead, do the "summarize from here" trick to keep everything valuable in place.

the real reception is the stuff people are building this week that they couldn't last week. that's the metric.
Sam Altman@sama
so fun to see the reception to 5.5! there is almost nothing that feels more gratifying to me than builders saying they find our tools useful.

For GBrain I built a proper eval harness. 145 queries, Opus-generated corpus. The retrieval stack uses graph based, vector based and Grep based strategies in combination.
The graph layer is worth +31 points on precision. Vector-only misses 170/261 correct answers that the full system finds. Keyword + vector + graph are three separable wins, each load-bearing.
Standard information retrieval metrics: the same ones Google uses to measure search quality.
Precision at 5: You ask a question, the system returns 5 results. How many of those 5 are actually useful? If 3 out of 5 are relevant, P@5 = 60%. It measures: am I wasting your time with junk results?
Recall at 5: For a given question, there might be 3 pages in the entire brain that are genuinely relevant. If the system finds all 3 in its top 5, R@5 = 100%. If it only finds 1, R@5 = 33%. It measures: am I missing things you need?
High precision = low noise.
High recall = nothing slips through.
GBrain's 97.9% R@5 means it almost never misses the right answer. The 49.1% P@5 means about half the results are relevant — which is good when you realize that for most queries there are only 1-2 right answers out of 17,888 pages, so 2.5 hits out of 5 is strong signal.
Entity resolution is zero-LLM-call: regex extracts typed links (works_at, invested_in, founded) on every write. Re-embed on write not on a timer, so decay = stale pages, and stale pages get rewritten when new info lands.

@ImpliedByLisa the talent was always there. the internet made it visible and the system still hasn’t caught up.

@eventuallyright @BitcoinMagazine @TheBitcoinConf historically yes, BTC dominance drops and alts run. but this cycle's different because ETFs are absorbing BTC supply that used to rotate into alts. the rotation might be slower this time.
English

@BitcoinMagazine @TheBitcoinConf Do Bitcoin outflows lead to Alt coin inflows? Transparently, I don't know shit about how the technology or finance system of crypto works.
The reason I am asking is because it seems like the Alts look ready for a run.
