After I finish listening to the "Classic Starts" Audiobook collection, I plan on working my way through this list:

[Dissident Teacher @educatedandfree]

It is done. Here are clickable links of over 400 books in the western canon, separated by age group. It's meant for all of you who want the best for your child's education and for your own as well.

The good news? Emily Dickinson was right when she said of books: "How frugal is the chariot that bears the human soul."

THIS is why I will stand on my soap box about only K-8 being compulsory!!! 9-12 should be based on what a student wants to do in life. If the want college, they can do all the pre-reqs. If they want to join a trade, they should start learning that trade. There is NO reason for a kid who wants to learn construction to take Algebra 2 or 3rd year arts

🚨 This is a prime example of fraud and waste inside California's homeless industrial complex

California bought this hotel for $8 million in 2020 and now wants $20 million to fix it. That is $625,000 per homeless person.

6 years later and NOTHING to show.

EXPOSE IT ALL.

There are now NINE states where more than 1 in 10 homes listed for sale have entered fire-sale territory.

Arizona.
Florida.
Louisiana.

These states lead the nation.

This is what happens when inventory rises faster than buyers can absorb it.

The housing market isn't crashing everywhere.

But the cracks are getting harder to ignore.

The glass is already being broken out on the new Throne Labs smart portable restrooms in Seattle, Washington

These bathrooms were installed just 2 weeks ago and are now already unusable because the windows are broken out

Cost to taxpayers is $116,250 per year, per bathroom

Seattle installed them as part of a one-year pilot program with the Seattle Department of Transportation to support increased foot traffic ahead of the 2026 FIFA World Cup

No one is surprised by this. The only surprise I have is it not always being completely covered in multiple layers of graffiti yet

Hey WA,
I need your help.
I am asking @GovBobFerguson to call a special session to suspend the CCA to immedietly lower gas prices and utilities.
If you want Bob to suspend the CCA to help working families and lower gasoline and electricity costs then share this post and like it.
Others in the legislator are starting to call for it.
Let's see if Bob actually cares about working class people in Washington.

UNDERWATER DATA CENTERS

China has achieved what it calls the world’s first fully operational, commercially running underwater AI data center off the coast of Shanghai.

The facility, developed in partnership with HiCloud Technology (also referred to as Hailanyun), features nearly 2,000 servers housed in sealed, submarine-grade capsules submerged in the ocean.

By leveraging the natural cooling power of seawater, it dramatically reduces energy demands cutting cooling costs by up to 90% compared to traditional land-based data centers. The entire system is powered by nearby offshore wind farms, making it highly renewable and energy-efficient.

The $226 million project was officially launched in June 2025, with construction completed later that year and full commercial operations beginning in recent weeks. It supports high-performance AI workloads, including GPU clusters from partners like China Telecom.

For context, the U.S. explored similar concepts through Microsoft’s Project Natick but quietly shelved the initiative in 2024 after successful trials, opting not to pursue large-scale commercial deployment.

This development highlights China’s aggressive push to address the massive energy and cooling challenges of scaling AI infrastructure.

This is an interesting engineering achievement in the AI infrastructure race, though scaling, maintenance, and long-term reliability in a marine environment will be key factors to watch.

Janicki is a fantastic company that was founded in Washington. People I know in the aerospace industry call Janicki the "gold standard" for machining critical parts and tools for the military, NASA and companies like SpaceX, Boeing, and Blue Origin. They hire Americans and lots of trades.

Just imagine, this could be a $800 million investment to expand in Washington. Great Falls is a fantastic location for them to expand to.

Congrats to Janicki and Montana!

This is where I go to research stock most of the time. There's a couple companies (IREN) that don't seem to fall in the category in which they are placed.
@EmmaStockNotes created a gem of a tool for finding value stocks. Beautiful.

I’m here for the long run.

More investing education, market analysis, company research, investing frameworks, portfolio tracking and the Top Percentile toolkit to come.

So my kid just finished a semester in the dorms at a CA junior college. His roommate is a previously homeless 18 year old that apparently got free dorm, free meal plan and even extra cash for checking the homeless box. He spent the cash on a gaming system. He dropped out the first month, but was allowed to stay in the dorm because... homeless. Today 5 of 6 suite mates got together to clean the dorm, to get their deposit back (and also to not be slobs).

This guy sat in a chair watching, because taxoayers payed his dorm deposit.
Anyway just a little report on CA efforts to house the homeless.

@voteholyk Washington State

REPEAL (Not Pause) Washington State Climate Commitment Act

And ... REPEAL the 2% increase on the state gas tax that hits every July, too.

@Sessler
@JimWalshLD19

[Isaac Holyk for U.S. Senate @voteholyk]

Hey WA,
Gas prices in WA have officially hit and all time high and it is going to get even worse because the gas tax automatically rises in July.
I am calling on @GovBobFerguson to do what is best for WA and call a special session to repeal the CCA and lower gas costs for WA immediately.
Gas would be about $4.25 a gallon if we didn't have all the state taxes and Climate Commitment Act that has done NOTHING!
It's a worthless piece of legisaltion that has only increased the cost of living for WA families so woke Democrats can feel like they are saving the planet.
News flash, woke politicians are not going to change the weather or save the planet but they sure will bankrupt everyone trying.

@EconNotes_ IREN. The company that sells to both NVIDIA and MICROSOFT.

[Hart of Learning @HartofLearning]

@danroberts0101 Great work. Early innings indeed. Long-term I'd love to see IREN data centers as the heart of new communities, literally the foundation.
Multi- story buildings with data centers at the bottom, then a floor of stores, a floor of communal space, floors for housing, gardens on top.

My high school AP English teacher bought me a suit and gave me gas money so I could afford to attend a merit scholarship interview weekend at Sewanee: The University of the South. Without her, I never would have landed a full ride worth close to $500k between tuition, room, board, books, fees, and annual international internships. She’s the reason I broke my family’s cycle of not even graduating from HS and thanks to her, I got a world-class education without student debt. I owe her so much. 🥹

A community college professor named Marty Lobdell taught the same study skills lecture for 30 years. The video quietly became one of the most watched educational recordings online, with over 10 million views.

He spent his career watching students fail not because they were lazy, but because no one had taught them how their brain actually works when learning something difficult.

The lecture, “Study Less Study Smart,” contains a powerful framework.

Your brain cannot sustain focus the way most people believe. Studies show the average learner hits a wall between 25 and 30 minutes. After that, efficiency collapses. You’re still sitting there, but almost nothing is being absorbed.

Lobdell told the story of a student who planned to study 6 hours a night, 5 nights a week. Thirty hours total. She failed every class. She was not lacking effort. She was confusing time near books with actual learning. The fix is simple: when focus drops, stop, take a 5 minute rewarding break, then return. That reset makes a massive difference.
He also destroyed the myth of highlighting and re reading. Recognition is not the same as recall. To prove it, he read 13 random letters. Almost no one remembered them. Then he turned them into “Happy Thursday.” The entire room recalled them instantly. The brain stores meaning, not repetition.

This is why elaborative encoding works so well.

Finally, he shared the most important principle: 80 percent of study time should be active recitation. Close the book and explain the material in your own words. Teach it to someone else or an empty chair. Retrieval is where real learning happens.

His closing line stuck with me: If this information does not change your
behaviour, you have not actually learned it.

The best students do not study more hours. They stop confusing the feeling of studying with the reality of learning.

@DividendBreeder The area I disagree with Ramsey is paying off lowest debt amount first. I say pay off debt with biggest interest rate first.
Though, I just don't acquire debt- pay off monthly.
