Welp, I guess this is the path... of LLMs? My favorite LLM for scientific research (FutureHouse's Platform) is now part of @EdisonSci and only offers a $200/month option or enterprise option. Nothing in between? Sad because I was actually using it to help patients.

Good reminders from @mitsuhiko. Not just for software dev. Cannot count the number of times the “roots” have anchored me: “I or someone else, planted something, and then I kept showing up, and eventually the thing had roots that went deeper than my enthusiasm on any given day.”

Agree with sentiment, but the logic can be disproven by reviewing your own paper from >1-5 years ago. Knowledge, judgement, taste change within individual. Under some circumstances, an individual provides better “external” feedback to themselves than the available (and willing) alternative sources.

Remember that you, by definition, cannot distinguish between a good idea and a failure of your own knowledge, judgement, or taste. This is why external (ideally expert) feedback is crucial

@bobbyfijan Same shock moving Charlottesville -> Cambridge during infant days. On weekends most Cambridge coffee shops open at 8AM, vs plentiful 7AM options in small college town… Dunkin is a drain on the universe

@bijans Auchinsloss? PBMs arguably bigger source of waste than healthcare fraud.

Some of this healthcare fraud video stuff is of course performative and bad use of data. But a lot of it isn't. Yet, not a single Dem that I'm aware of at national/state/big city level is making the case for good government, efficiency, and catching and stopping healthcare fraud at its core. They've handed the entire narrative to Rs. That reputational hole / letting voters brand Ds as sclerotic, wasteful spenders, beholden to interest groups and who enrich fraudsters and raise your taxes to do so vs. the “efficient” R image will take a generation to climb out of.

Not sure whether my point was misunderstood—relative to low COL states, MA is losing population. The driver is not high net worth individuals moving, though, it is people that are priced out (which is due to largely non-partisan, boring issues, not headline-grabbing issues). Cost tells us most of the story—MA is a very desirable place live. Infrastructure is incredible relative to other parts of USA, evident by COL.

check the numbers of net out migration by tax-paying regular citizens in recent years in MA. Total population change is misleading due to the enormous per capita increase in relatively unskilled/needy immigrants (except on Nantucket) who are mostly here illegally. Please comment on our amazing, beautiful, well-functioning infrastructure and super low energy costs, the envy of the nation. And also how we have zero fraud and corruption. I look forward to continuing the conversation on these topics.

My colleagues that I work with every day closely are amazing. The state - really not so great and I would love to live somewhere else. Every day it is something annoying, the legislature cares more about insisting that men can use ALL women's restrooms at my institution (a harsh law is enforced) than about fixing infrastructure.

Residents exiting Massachusetts took a net of $4.2 Billion in adjusted gross income with them in 2023, one of the largest totals in the country, after a tax on millionaires took effect - Bloomberg

Not disagreeing with specifics, but net flows of revenue and population suggest tax policy is beneficial and that when people speak with their wallets, they find the services provided and culture outweigh the costs. Most issues causing migration out of MA are self-inflicted, non-partisan (e.g., localities non-compliant with MBTA communities act; local zoning constraining housing supply and inflating housing costs, etc.).

Zeitgeist of normal taxpayers is still - what do we get for our money? A lot of social programs of questionable benefit (other than favorable press from legacy media for politicians and their friends), distracting from infrastructure problems that persist and degrade quality of life for all.

@JustinPerryPhD @LindaGGriffith1 Well, the alternatives (theory-based modeling, extrapolation of empirical results from other regions with similar policies) generally find the same result as this analysis from the first year of implementation in MA.

@LindaGGriffith1 @MedlockGreg A fixed time point analysis to argue why a millionaire tax is a net-benefit is quite misleading. We are facing similar things in CT, with the constant stream of punitive policies passed by a supermajority in the state. It's really sad to see, given how beautiful NE is.

Have any parents ever discovered that their 5 year old did indeed have a disease that made it too painful to walk?

@emmma_camp_ The methodology for the survey doesn’t seem to be public, and only 877 preschool teachers responded (far lower numbers for k-3). Amongst preschool teachers, I don’t think tenure is long enough for even a modest fraction of those teachers to have been teaching pre-COVID.

If it's parenting, why? What made parents just stop ensuring their kids develop basic motor skills?

Hopefully this experiment shows other folks how peer review and collaborative work are going to evolve with AI... you can just "do the thing" now. I came away with a much better understanding and appreciation of GPU-kallisto! cc @lpachter

I definitely found that the bgzip vs. gzip point in @pmelsted's paper is critical. GPU-kallisto takes 10X as long (which I learned through trial and error, as I did not catch in Claude's implementation that it did not use bgzip). Opus 4.6 also was not terrific at figuring out compilation issues (though this is a pretty unique approach). If anyone knows of skills out there that optimize this, I'd love to learn more.

I was curious how @pmelsted's new GPU-kallisto implementation affects compute costs. Given the massive (50X!) improvement in speed, this wasn't straightforward. Instead of just asking "ackchyually, is it cheaper", my friend Claude and I did the analysis!

Excited to share this preprint that describes my latest work on using GPUs to accelerate processing of RNA-seq data. The title says it all: "RNA-seq analysis in seconds using GPUs" now on biorxiv biorxiv.org/content/10.648… Figure 1 shows they key result
