Embarrassing to admit but just found out I was still paying for copilot via GitHub from back in 2023 when that was useful

I like using muse wonder for code reviews because it always tells me my code is awesome and can’t be improved. My colleagues prefer when I use any other model.

In all the time we've spent building PostHog I've never once worried about what our moat was. If you're a founder, just build a good product.

Here is crazy that pretty much every F500 CEO is complicit in
1. They self insure - good thing
2. They hire a third party administrator that is owned by a Too Big To Care insurance company. - Really Bad
3. They allow that TPA to deny care determined by the doctors that the TPA selected to be in network - Horrifically bad
4. They don’t tell the CEOs about the denied care , when it’s their money and ultimately their decision as to whether they should pay for care - more horrific
5. Employees and their families get sicker while the denial is appealed. Again, when the ceo has no clue. Even if the cost to help the patient could a small amount. - insane
Big self insured companies do dumb shit that makes the cost of care in this country far higher than it should be.
It’s not their core competency and they often listen to consultants whose interests are not aligned with theirs.

Running a business is just realizing how dumb you were 6 months ago every 6 months
The PBM fee-disclosure rule (finalized on 10/29) doesn’t just require self-funded plans to disclose what was paid and what it kept. When a TPA contracts for pharmacy services on the employer's behalf, the TPA has to obtain the information from the PBM. So TPA's own contracts may come under scrutiny too. Very good step!

On 11/4, federal regulators refused to re-certify two of the arbitrators who decide surprise-billing disputes under the No Surprises Act.
One of them was the system's busiest: Island Peer Review Organization decided 204,611 disputes in 2025 and sided with providers 98.4% of the time, with a median award of 601% of the in-network rate.
The arbitrator is picked by the provider who files, paid $425–$800 per dispute decided, and paid nothing when a dispute is ruled ineligible — so ruling for providers is how an arbitrator keeps the work coming.

My current “software factory” for side projects seems like a good balance of cost / efficiency for most individual builders:
1) use your local machine (I know, software factory red flag)
2) make claude code your builder with remote control, keep computer awake, auto-fix, open PRs automatically all turned on
3) setup codex to auto-review every PR
Control from Claude app on your phone

while it won’t be fun for our on-call friends for a couple months, at least this timeline is hilarious

Breaking News: John D. Rockefeller IV has died. He championed health insurance expansion over 30 years as a senator from West Virginia. nyti.ms/4zuFtbf
When I first started working in the self-insured healthcare benefits space, I thought the SPD was the key to all problems: a 100+ page legal document defining how the plan functions?! Perfect for both AI and bad for humans, this will be a breeze.
In the years since, I’ve learned that plan docs are almost always driven by a broker/carrier template and often out of date. It’s much better to have the claims system drive the SPD (in-sync and auditable), but this adds friction and cost to the migration process. So AI's first job isn't adjudication — it's flagging the clauses where the document says something nobody at the employer actually decided, before those clauses impact real-world claims.

The provider network is the powerhouse of the healthcare ecosystem. Providers usually want to participate so they receive commercial rate reimbursement and employers want to be a part so their employees can receive care with less friction. A lot of the system seems to be betting on the provider-side friction decreasing soon (ai, cash pay, direct contracts, etc.), but I’m not sure I see enough incentive for providers to make this change rapidly barring massive regulation change.

i've reproduced the results from the MIT blog post today on weight-space programming. but one additional result i have to add: this is a new, step-change emerging capability that's appeared in just the latest set of models.
“make my ai better, make no mistakes”
We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵
Blog: rikiyat.github.io/blog/weigh…
Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math.

Many such cases over the next ~6-12 months
This is INSANE. Cisco’s president Jeetu Patel has given a 27-year-old engineer unlimited AI tokens to try to rewrite 98% of the company’s legacy code within 24 months, Fortune reports.
Padmanabhan Krishnamurthy thinks he can do it with a two-person team. He has just four weeks to prove the approach.

BREAKING: The average cost of a family’s annual health insurance premium in the US is up +$1,303 YoY, or +5%, to a record $28,303.
This marks the 4th consecutive annual increase of at least +$1,300.
Over this period, the average annual premium for family coverage has surged +$5,884, or +26%.
To put this into perspective, CPI inflation has risen +13% over the same period, or half as much.
Since 1999, the average health insurance premium for a family has soared +$22,494, or +387%.
This represents an average annual growth rate of +6.1%, well above CPI inflation at +2.6% over the same period.
Health insurance has never been more expensive.
