.@pmarca: "The person who writes down the thing has tremendous power."

"There are so few people who will just like write down the thing.

And so we see this at companies all the time, which is, one of the ways you find the up-and-comers at a tech company is just, okay, who wrote down the plan?

And, you know, that doesn't mean they came up with everything. And that doesn't mean that they had all the ideas, but they're actually able to organize their thoughts and then actually have the energy and the motivation and the skill to be able to communicate in a written form.

That actually stands out."

The @NASAArtemis crew captured this view of the Moon eclipsing the Sun yesterday. The three "stars" to the lower right of the Moon are actually planets. The middle one has a slightly red tint.

That's Mars.

If you’re tired of seeing my face in your newsfeed or on the TV, apologies in advance, because it’s about to get a lot worse. By the end of the year, you’re going to be absolutely sick of me, due to America’s ever widening skills gap, and our ongoing attempts to close it with a record number of work ethic scholarships from mikeroweWORKS, and therefor, a record number of invitations to apply.

The situation is serious. Skilled tradespeople are retiring much faster than they’re being replaced. For every 5 that leave the workforce, two come in. The math is not sustainable, and not a week goes by that I don’t hear from some industry leader wondering if I can help with their recruiting challenges. Every trade is in demand like never before. In fact, there’s been so much outreach from so many CEO’s and elected officials, that we’ve doubled the size of our scholarship fund, and extended the application period this year from six weeks to nine months.

Last year, we received 10X the number of applications we normally get, and this year, with the disruption of AI, I suspect the number will be even higher. These are AI-proof, six-figure jobs that don’t require college debt, but instead, training. Thus, I will be cluttering up the media landscape with an onslaught of invitations to apply for scholarships, (like the one attached,) and good-natured appeals to support our efforts with a modest (or immodest) donation.

Toward that end, I’m pleased to announce that the enrollment period is officially open. Funds are now available to help train the next generation of skilled workers. My goal this year is to award $10 million in scholarships, and you’re invited to apply today. Or, if the spirit moves you, to support our efforts with a donation of any size. The donate button is big and red and hard to miss at https://t.co/uolhGspFtN.

If nothing else, please share this, so others can be similarly annoyed with another unsolicited invitation to help us close America's skills gap.

We have reached a stage in our country where there are only two sides to every issue and every incident. Each side lives in protected echo chambers which are provided with a curated set of ‘facts’ and/or video footage from certain camera angles that are consistent with the preexisting views and conclusions of that side.

Individuals are ‘convicted’ of serious crimes in the headlines, by politicians appealing to their base, and ultimately in the minds of the public, or they are exonerated, before all of the facts are in and a detailed investigation has been completed.

This is not good for America. We need to go back to a world where we suspend judgment and await the conclusions of a detailed investigation before we convict or exonerate. Let’s not forget that a man is presumed innocent until proven guilty.

Rushing to judgment helps no one and harms us all. It also greatly elevates the temperature, which keeps potential targets of law enforcement and those who enforce our laws on edge, massively increasing the risk to all.

We need to take a deep breath and reserve judgment before this gets even more out of control.

@CityofBA The weather won’t be bad tomorrow morning, Friday January 23rd, so why not carry out the separate trash and recycling runs at least that day? There’s no safety issue on the 23rd, all the weather models show very little precipitation until late Friday.

More evidence on the link between metabolic health, muscle, and the brain.

This review (open access) makes a compelling argument that insulin resistance, chronic hyperglycaemia, mitochondrial dysfunction, oxidative stress, and inflammation interact to promote both muscle wasting and neurodegeneration.

One of the many, many reasons exercise has such a strong benefit for the entire physiological system.

It's not a guarantee, but avoiding type 2 diabetes is a pretty good way to avoid both sarcopenia & cognitive decline (especially Alzheimer's).

On Nov 13th, there was a solar particle event that resulted in beautiful blankets of aurora. You may have seen it. We had the most amazing view and our crew collectively took thousands of photos and dozens of time lapses. Here is one of those time lapses. Nov 13th. Nikon Z9 | 14mm.

Two years of vigorous exercise reversed the age-related structural changes in the hearts of sedentary 50-year-olds by about 20 years

The protocol used by Dr. Ben Levine's team:

• Norwegian 4x4 intervals (initially once per week, later increased to twice per week, eventually returning to once/week)
• Strength training (twice weekly)
• Recovery aerobics (20-30 minutes of light exercise)
• Endurance sessions (weekly 1+ hour endurance training, plus a separate 30-min base-pace session)

A few notes:

• Exercise intensity and frequency gradually increased from the start
• By 6 months, participants were exercising 5–6 hours/week

[Vivek Ramaswamy @VivekGRamaswamy]

Here’s a key point about our mission at DOGE: eliminating bureaucratic regulations isn’t a mere policy preference. It’s a legal *mandate* from the U.S. Supreme Court:
- West Virginia v. EPA (2022) held that agencies cannot decide major questions of economic or political significance without "clear congressional authorization." This applies to *thousands* of rules that never passed Congress.
- In Loper Bright v. Raimondo (2024), the Court ended Chevron deference, which means agencies can't foist their own interpretations of the law onto the American people. Over 18,000 federal cases cited the Chevron doctrine, often to uphold regulations, many of which are now null & void.
- In SEC v. Jarkesy (2024), SCOTUS restricted the use of "administrative law judges" by agencies. The same agency that wrote the rules shouldn't be able to prosecute citizens in “courts” that it controls.
- In Corner Post v. Board of Governors (2024), the Court held that new businesses can challenge old regulations, greatly expanding the statute of limitations & opening many more rules up for scrutiny. So we shouldn't just look at rules passed in the last 4 years, but over the past 4 decades (or more).

DOGE is ready help the U.S. government conform to the U.S. Constitution once again. @elonmusk and I are ready to serve. 🇺🇸

[JD Vance @JDVance]

One of the most important skills I see in successful (and good) people is to constantly reevaluate assumptions. They make predictions based on various inputs, some of them unknown, and reevaluate based on what they got right and wrong. They trust people not because they're always right--no one is--but because if you're constantly seeking the truth it's easy to identify those who are doing the same.

If you were confident that Donald J. Trump was going to lose, maybe you should question what else you "know" about him. Maybe the people who misled you about his electoral chances have misled you about other things.

In the words of Cormac McCarthy, "If the rule you followed brought you to this, of what use was the rule?"

[Bill Day @billday]

It's time to reimagine minimizing government and maximizing liberty, with the Constitution as the bedrock, from First Principles. What an incredible opportunity we have!

[Bill Ackman @BillAckman]

Imagine if we were to consider and reconsider all of the required functions of government using a blank-sheet-of-paper approach and then rebuild from the ground up the necessary agencies to fulfill these requirements, bearing in mind the technologies available today, ie, AI and others, that can be implemented to achieve the necessary outcomes.

How much would we save and how much more efficient and effective would it be?

As of last night, Democrats no longer want to kill the filibuster, and they aren't talking about the Electoral College quite as much. Will they learn to appreciate the 1st and 2nd Amendment as well?
