[Patrick Heizer @PatrickHeizer]

Many new followers, so an introduction:

By day, I'm a cardiovascular scientist at AstraZeneca.

I also own & operate a permaculture farm. Since '21, we've planted chestnut, pawpaw, & more. This year we began silvopasture rotational grazing.

I'm an avid reader, especially Camus!

[Adrian Bonenberger @AdrianBonenber1]

Thanks to @PatrickHeizer for showing me around his remarkable farm (and for this delicious honey) — he's organized the farm for efficiency and for correctness, to "work" for and with his family — it's a great project and designed to be emulated. Stop by and check it out!

[Patrick Heizer @PatrickHeizer]

@squarepianocase Yes, I'll re-emphasize the "political" in my statement and did not not mean anything beyond it.

Operationally, it might be something like algorithmic pricing of any edible food at the POS.

But Idk, haven't thought about it much deeper than "political."

[Patrick Heizer @PatrickHeizer]

One of the easiest political wins sitting right there for the taking would be making algorithmic pricing of groceries illegal.

Bet it polls at 90+ popularity.

Walmart and Kroger are quietly rolling out an internal store technology across America that could either modernize retail or bankrupt the middle-class family budget.

Starting across thousands of locations heading into 2027, traditional paper price tags are being ripped off grocery shelves and replaced with cloud-connected digital screens. Raise the price of bottled water by 20 percent the second the afternoon temperature hits 90 degrees. Surge the cost of ground beef, milk, and sandwich bread between 5 PM and 6 PM when exhausted commuters are rushing home from work. Drop prices at 10 AM on a Tuesday, then hike them right back up the minute the after-school crowd walks through the sliding doors.

Every price change happens wirelessly in seconds from a central corporate dashboard. No store employee has to touch a single shelf.

Walmart has already signed a massive deployment deal with VusionGroup to wire 2,300 American supercenters with EdgeSense digital shelf rails by 2027. Kroger is expanding its own Microsoft-backed system called EDGE across hundreds of supermarkets. Over 60 million digital price tags are already blinking on US grocery aisles right now.

This is not supply chain inflation. This is Uber-style surge pricing built directly into the shelves where Americans buy baby formula, eggs, and medicine.

Last week I sat down for coffee with a former retail pricing director who spent 14 years building supermarket margin algorithms before leaving the industry. What he shared over the table completely changed how I look at a grocery aisle.

"Retailers just turned static shelves into live stock tickers. The question is not whether grocery chains will use instant price changes, because they already spent billions installing the hardware. The question is how much extra money a family of four will lose every week simply because both parents work until 5 PM and cannot shop during off-peak hours."

Here is how the digital grocery pricing system actually works, how it tracks you in the aisle, and the exact phone settings and checkout playbook you need to beat it.

"To put that in perspective, Republicans haven't reached 56% of the [midterm] vote since 1928."

[Lucas Romero @LucaRomero]

No es una derrota de Trump, es una catástrofe. El escrutinio continua y la diferencia en el voto popular ya es de casi de 14 puntos (16 millones de votos). Es la victoria más aplastante desde 1974. Para tener una idea, los Republicanos no llegan al 56% de los votos desde 1928.

Influenza season continues to hit sooner than typical.

It's a notable risk for the elderly, small children, the immunocompromised, or those with chronic conditions. If those describe you or your loved ones, consider taking the annual influenza vaccination.

[Patrick Heizer @PatrickHeizer]

Note that this was a study of 65yo diabetics, so unless that describes you, it's irrelevant.

Moreover, it was a retrospective and observational study, meaning we have no understanding as to *why* they stopped the GLP-1, or if the stoppage was *causally* related to mortality.

[The Lancet @TheLancet]

Stopping GLP-1 treatment linked to twice the risk of heart attack, stroke or death compared with continuing, in people with type 2 diabetes and no cardiovascular disease, according to a new study.

My mutual @AdrianBonenber1 stopped by the farm and was kind enough to bring me a copy of his book.

I'm excited to read it and you should check it out too!

[Patrick Heizer @PatrickHeizer]

@TheLincoln Okay, but what about Mein Kampf?

[Patrick Heizer @PatrickHeizer]

The novel that just won the Booker Prize has a lower score on Goodreads than Mein Kampf.

[Patrick Heizer @PatrickHeizer]

My wife sent me our eldest's very first school photo and I'm overwhelmed with a sense that time is going too fast. I just want to go back to the NICU and relive it all again.

[Patrick Heizer @PatrickHeizer]

@codechallenged 1) Do nothing and "leave" them there. Run a lawnmower over them if you want to speed degradation.

2) Rake them into flower/garden beds for mulch.

3) Rake them into a pile and bring to the compost pile.

[Patrick Heizer @PatrickHeizer]

Remember, they are called "leaves" for a reason.

[lex @lexisoupertramp]

Big Landscaping has boomers in such an ironclad chokehold, I tried explaining to my mom that it's actually better for nature not to rake the leaves and she looked at me like I was trying to tell her fairies are real

@amwilson_opera A brief but fantastic read.

#14 The Uncontrollability Of the World by Harmut Rosa

A short treatise on how one of the driving cultural forces of "modernity" is an incessant desire to make the world engineerable, predictable, available, and accessible, i.e. controllable, yet it's ultimately the **uncontrollability** of the world that allows us to resonate with it and become human in the process.

Rating: Fantastic to the point of now joining the books I frequently recommend.

[Patrick Heizer @PatrickHeizer]

@Tyler_Menzer Are you thinking nutrient runoff into the watershed?

If so, I agree that organic material near impervious surfaces, and especially drains, should be cleaned.

[Patrick Heizer @PatrickHeizer]

@VGrubsky Thought you were going to say use an electric mower to increase their surface area to volume ratio and speed up degradation.

[Patrick Heizer @PatrickHeizer]

@Tyler_Menzer It's certainly not the highest leverage intervention point!

"Do not bow down before anything that cannot give you life. And if you have ever fallen, get back up."

Truly the Pope for our times.

[Pope Leo XIV @Pontifex]

Today idols arise and demand our worship: success at any cost, money, an obsession with appearance, popularity, or the unrestrained pursuit of pleasure. Sometimes, in order to win the approval of others, we may go so far as to lie, betray, or humiliate someone on social media. Do not bow down before anything that cannot give you life. And if you have ever fallen, get back up. Do not allow anything or anyone to take away the freedom God has given you. #ApostolicJourney #Argentina

Foul shots remain the most underrated aspect of basketball. They straight up win you games.

Every team not shooting 75%+ should be ashamed.

#15 On the Equality Of All Things by Carlo Rovelli

An concise overview of Rovelli's thoughts about a range of topics across physics and philosophy.

Rating: Fine enough, some highlights, but wouldn't recommend unless highly interested.

[Patrick Heizer @PatrickHeizer]

Thread: Books I've read in 2026

Written in simple prose that is both beautiful and haunting, this is the story of the life of Arseny, a 15th century Russian medicine man, a tale of magical realism and redemption that spans from rural Russia to Jerusalem.

Rating: Solid, there are truths within these pages that I understand, yet don't comprehend.

@Bookish_Drifter I don't know! The only options I thought of were 1) people just really didn't like the book and 2) it was review bombed for some reason.

[Patrick Heizer @PatrickHeizer]

Even with a broken arm, the little one insists on helping fill the trough.

[Patrick Heizer @PatrickHeizer]

Every night after dinner, we go out as a family and do the evening farm chores. While working, we talk about our days, life, the farm, and even run around or play with the water hose.

I'm certainly not the richest man, but I am the wealthiest
