Few people in the United States have seen what great infrastructure looks like. This is the future that is scary to many. You’ll notice at one point the train, a car carrying cargo, bicycles, bicycle parking, and wide sidewalks are all in frame with a park in the middle.

A lot of people assumed that the United States was basically finished as a nation, and acted accordingly. I'm starting to think those people are about to have a very bad time.

This new Reuters report is stunning. A week before the U.S. captured Venezuela's leader, JD Vance reportedly met at a private Montana ski club with John Addison, an oil trader who had given $300,000 to help elect Vance to the Senate in 2022. Vance allegedly asked how fast Venezuela's oil could be sold if America took control of it. Both men deny the meeting. Flight records show their planes parked together that day. Two days after the Venezuela operation, Energy Secretary Chris Wright called Addison and offered his company, Vitol, the job of selling Venezuela's oil. There was no public bidding. Vitol and one rival have since made hundreds of millions of dollars. Addison and his wife also gave $7 million to help elect Trump, and he now chairs a board advising Secretary Wright. Congress has a duty to act. We should bring Secretary Wright, Vitol, and Addison in to testify under oath. We should demand the phone records, emails, and flight logs. We should find out whether anyone got a heads-up about a military operation. And we should require open, competitive bidding before any company profits from our foreign policy. If nothing was wrong, let’s see the records. reuters.com/business/energy/…

One of the least compelling points mainstream Christian's make to Latter Day Saints is implying that the LDS belief that men become like God is bad. That belief, and the doctrines that spring from it, are some of the most genius creations of Mormon Doctrine. I am no longer LDS, but think the mainstream Christian view is that we are creatures of God, not his children. Children can grow up to be like their parents. Also, what kind of a parent wants their children to never reach the same level they are at? That isn't love. Love is wanting everything you have for your child, and more! Mainstream Christians, if they want to persuade LDS folk, need to find a better angle.

It'll be a huge miscalculation by the @GOP if they don't have a candidate for 2028 that opposed MAGA. If they want a chance at moderates they will likely need to get some anti-Trump GOP nominees in there. But will Republicans only put forward MAGA candidates as the nominee?

I think that raising income for wage earners is a tide that rises all the boats in the harbor. Society is more peaceful when wage earners have a good life. It's better for them, and its better for those who own the capital as well.
When I’m wrong, I’m wrong. I thought when unemployment was low, GDP was hi, household income rose, it meant everyone was winning. Not true. The American economy has decoupled the economic progress of asset owners from wage earners to such a degree that broad based measures of success are no longer reliable measures of progress. This single issue of asset ownership vs progress of wage earners will be the defining issue in all future elections. Other issues will get caught in the interpretation (price of eggs, Iran war, price of gas etc) but the candidate that realizes that those are downstream of asset vs wage earners and gets their messaging focused on it will win. No amount of money spent in an election or gerrymandering will change this outcome. That is what I learned on Nov3.

He needs to return the crypto scam money to the public treasury. It was the most egregious thing a president has ever done. $1B a week before inauguration.

The gap between an average engineer and the best engineers was never quite 10x, but it was meaningful. AI has made the gap at least 100x.

Never Trump conservative opposition in 2016 was premised on two prongs: 1. Trump lacked character/temperament, & 2. Trump would lose, & ultimately discredit the GOP/hurt conservatism The former was obviously & demonstrably true The latter was FINALLY established this week

This reminds me of that one time in law school I tore the ligament in my ankle playing basketball on campus during lunch. I sent a picture of my foot to my professor for why I was missing so he didn’t think I was lying. It was black and blue from my toes to mid shin and insanely swollen. In his response he said “please don’t ever send me pictures of your feet again.”

A Thomas Massie/Mitt Romney presidential ticket would have Democrats scared. Because a lot of us normies would be persuaded now by those two.

I think a @ossoff / @MittRomney ticket would be even better. Let's work together for some change with reasonable people.

Trump was offering $5,000 bribe checks. Republicans were the ones offering "free money." That is different than Democrats saying "we will raise the minimum wage" or "offer universal healthcare with your taxes and pay less than private insurance." That's better bang for the buck

Some of the most vindicated individuals in American political history. Trump was always exactly what they said he was.

Now we'll finally learn what's in the Epstein files. Mike Johnson is no longer in a position to shut down the House in order to prevent votes on measures to force their release. It's time. It's past time.

About 24 hours from now... Fox News is suddenly going to remember that the National Debt has ballooned to over $40 TRILLION, and they're going to expect the Democrats to fix that

Several figures here aren’t federal results or NY-specific. The $472B combines US wide pledges: Micron's $250B is nationwide (NY site $100B) Anthropic's $50B covers TX and NY. The 48% murder drop is from NY's state run GIVE program (28 departments, Jan – May 2026). arkolith.com/news/news-micr… therepublic.com/?p=843020 governor.ny.gov/news/safer-str…

If you've ever wondered why smart TVs are so cheap, this is why. @log4j rooted his Samsung and found an always-on hot mic, automatic content recognition, geolocation, network mapping, ad targeting and user profiling, shared with Samsung's "400 partners". A lot of it can be blocked in <15 min, wrote a basic guide below. What your TV is doing The main culprit is ACR (automatic content recognition). Your TV screenshots what's on screen, fingerprints it, and sends it home to build your ad profile. Samsung does it every 500ms, LG every 10ms [1]. What is insane: it happens on connected devices too. Plug in your laptop, your console, your work machine, and your TV can fingerprint that via HDMI [1]. He also found that if your Samsung doesn't have a mic, it'll look for one from a connected soundbar or bluetooth device. teapaw.org/log4j/status/211376224… It's on by default, and you likely agreed to it on the setup screen you clicked through in 10 seconds. Step 1: Turn off ACR Samsung: Terms & Privacy → Viewing Information Services LG: Live Plus Vizio: Viewing Data Roku: "Use info from TV inputs" Sony/Google TV: Samba Interactive TV Menus vary by model, but those are the names to look for. While you're in there, opt out of interest-based ads, reset your advertising ID, decline every optional privacy agreement, turn off voice recognition, and delete apps you never open. Step 2: Give smart devices their own network Put the TV, cameras, speakers and vacuum on your router's guest/IoT network. The logic is simple: these devices rarely get patched. If one gets compromised (getting drastically more frequent with AI), it shouldn't be able to see your other devices or home network. Step 3: Block trackers for the whole house with DNS-level filtering NextDNS (cloud-based) is easy and has a solid free plan. Pi-hole is a little bit more work if you prefer self hosting. For simplicity we'll focus on the former. 1. Sign up at nextdns.io (free tier is plenty) 2. Privacy tab: add a blocklist (OISD is a good bet) and turn on Native Tracking Protection for Samsung, LG, Roku, Amazon (see attached image) 3. Setup tab: copy your endpoint 4. Paste it into your router's DNS settings as DNS-over-HTTPS/TLS (or use the IPs + "Link IP" if your router only does plain DNS) 5. Bonus: block outbound port 53 except to your router. Some devices hardcode their own DNS to get around you Then open the NextDNS logs and watch how often your TV phones home. It's eye-opening. If an app or update breaks, find the domain in the logs and allowlist it. Why they do this TV prices are down 97% since 2000 [2]. Most of that is better manufacturing and brutal competition. But once margins on the hardware hit zero, the cost moved to you. In Q3 2024, Vizio lost $6.7M selling TVs and made $115.8M in gross profit from ads and viewing data [3]. They've said on earnings calls that they keep TV prices low to grow the audience they sell to advertisers. Walmart bought them in 2024. This isn't a conspiracy theory either. Vizio paid $2.2M to the FTC in 2017 for tracking 11 million TVs without consent. Last December, Texas sued Samsung, LG, Sony, Hisense and TCL over ACR. Samsung and LG have since agreed to stop collecting that data without explicit consent [4]. TL;DR 1. ACR off 2. Ads + voice off 3. Smart devices on their own network 4. NextDNS filtering on the router Sources: [1] ACR study: arxiv.org/abs/2409.06203 [2] Cost of US consumer goods: aei.org/economics/chart-of-t… [3] Vizio Q3 2024: sec.gov/Archives/edgar/data/… [4] Texas v.

i own a relatively new (2025) samsung tv. i kept getting weirdly targeted ads. i tried reversing the firmware but it was aes encrypted and no keys unless tear it apart and do uart/jtag magic. zero days it is. root shell on new samsung TVs! discovered PRIVACY HORROR. write up?

Got a cheap embroidery machine off amazon for $300 where the biggest complaint is the mandatory $12/mo app that you’re forced to use. Had ChatGPT create its own app that communicates with the machine. Generative art patches incoming!
