The French 🇫🇷 don't use air-conditioning even during hot summer months, to save the planet. Thank you for your sacrifice 🙏

[Tony Aubé @aubetony]

After a hellish week in a Paris Airbnb with no AC (100°F outside, 108°F+ inside), I started looking into why the French are so opposed to AC.
There's many reasons: bureaucracy, poverty, etc. But the main one is decades of environmental campaigns that convinced people AC is the devil.
The result? You can't escape the heat. Most buses, metro lines, and shopping malls have no AC.
This Monday, 850 schools are closing because classroom temperatures exceed 104°F.
In Nantes, they built a brand-new train station and a hospital without AC for environmental reasons. The station is now partially closed because it's become a "furnace" that endangers travelers. Hospitals are covering windows with emergency foil blankets to protect patients.
The French demonize air conditioning because it creates carbon emissions that contribute to climate change. Never mind that France already has one of most carbon-free electricity in the world thanks to nuclear, or that it accounts for less than 1% of global emissions.
They also oppose AC because it "just displace the problem" by dumping heat into the street. Never mind that studies suggest even if an entire city were air-conditioned, the increase in outdoor temperature would be at most about 1°F.
Instead, people are willing to endure 104°F+ indoors to avoid a marginal increase outdoors.
This ideology kills more people than firearms in the United States.
Across Europe, between 50,000 and 70,000 people die from heat every year, mostly the elderly and the poor. Compare that to roughly 44,000 Americans killed by firearms.
For comparison, despite having a similar population, deserts, and more extreme temperatures, the United States has only about 2,500 heat-related deaths per year thanks to widespread AC.
That's what bothers me most. The moralizing posture completely detached from reality.
People feel morally superior for "not polluting." They criticize America and its guns while tolerating policies that kills even more people.
I share this anecdote because I know it's shocking to Americans. Here, schools or hospitals reaching 104°F would be unnaceptable.
The absurdity is immediately obvious to us because we're looking from the outside. We see the gap between moral intentions and real-world consequences.
But we're no different. In America, we have dozens of similar issues where we're just as irrational, and we've become blind to them because the solution isn't politically acceptable.
How do can we bring back logic and pragmatism in our societies ahead of irrational political ideological ?

Brazil: For the first time ever, a Brazilian husband and wife were sentenced to prison for the “crime” of homeschooling their daughters.

The judge held that the children needed more diversity, gender and sex education.

Keep in mind, the mother holds degrees in mathematics and pedagogy and the children perform well.

The sentence is suspended, pending appeal.

Pray for this precious family.

What people are missing about the US government's AI regulation announcement:

ID verification will now be forced on all accounts to prove citizenship.

Frontier labs will take your data, and your sovereignty is officially dead.

A permanent underclass division and a total control society are beginning right now.

People ignored me when I started saying this last year, but it is happening right in front of our eyes.

Get into Open-Source and Sovereign AI.

Advancing together through collective intelligence is the only way to fight back.

Local AI hardware = capacity × bandwidth × software stack

- Capacity tells you what fits
- Bandwidth tells you how hard the box can breathe
- The software stack tells you how much of the spec sheet you can actually cash out.

Hardware by Memory Bandwidth
- Mac Studio M3 Ultra: up to 512GB @ 819 GB/s
- RTX PRO 6000 Blackwell: 96GB @ 1792 GB/s
- RTX 5090: 32GB @ 1792 GB/s
- RTX 4090: 24GB @ 1008 GB/s
- RX 7900 XTX: 24GB @ 960 GB/s
- Radeon PRO W7900: 48GB @ 864 GB/s
- AMD Radeon AI PRO R9700: 32GB @ 640 GB/s
- Intel Arc Pro B65: 32GB @ ~608 GB/s
- Tenstorrent Wormhole n300: 24GB @ 576 GB/s
- Tenstorrent Blackhole p150: 32GB @ 512 GB/s + 800G
- MacBook Pro M5 Max: 460-614 GB/s
- MacBook Pro M5 Pro: 307 GB/s
- DGX Spark: 128GB @ 273 GB/s (coherent + CUDA)
- Mac mini M4 Pro: 273 GB/s
- Ryzen AI Max / Strix Halo: ~256 GB/s (~96GB usable GPU)
- MacBook Air M5: 153 GB/s
- Snapdragon X2 Elite: 152-228 GB/s
- Intel Lunar Lake: 136 GB/s
- Snapdragon X Elite: 135 GB/s
- Mac mini M4: 120 GB/s
- Arc Pro B60: 24GB @ ~456 GB/s

Verdict

- GPUs are still the bandwidth kings

- Apple wins: stupid amounts of memory, don’t want to shard across GPUs
- Apple loses: when raw tokens/sec & concurrency matter more

- DGX Spark: coherent memory + NVIDIA stack

- Strix Halo / Ryzen AI Max: first real x86 unified-memory contender

- Tenstorrent: fully OSS stack, excited to see this mature

Fitting ≠ serving

Even if it fits, you still pay for
- bandwidth during decode
- KV cache growth
- dequantization
- batching + concurrency
- scheduler quality
- framework overhead

The only mental model that matters:

1. What must fit?
2. What bandwidth tier do I need?
3. What software stack can actually deliver it?

In short:
- NVIDIA → fastest raw speed
- Apple Studio M3 Ultra → biggest one-box memory
- Strix Halo → first real x86 unified
- DGX Spark → coherent NVIDIA dev appliance
- AMD / Intel Arc → rising alternatives
- Tenstorrent → fully opensource stack

Do ask: “which bottleneck am I buying?”

Not: “which hardware is best?”

Schools make sure that every child knows Thomas Jefferson had slaves, and they carry out a massive agenda to use slavery to attack heritage Americans, so I always wondered why we didn’t hear the names of the big slave owning families… I think I found out why.

Today, on my final day as Director of National Intelligence, I’m releasing never-before-seen communications and documents exposing how Dr. Fauci provided millions in US taxpayer dollars to fund dangerous gain-of-function research at the Wuhan lab, worked with politicized elements within the Intelligence Community to suppress the truth about his actions and hide the virus’ lab-leak origins, and lied to Congress while under oath in 2024. It’s time you know the truth.

Research shows a 72-hour fast can completely rebuild your immune system.

A study from the University of Southern California has revealed that fasting for 72 hours can trigger a complete regeneration of the immune system.
Researchers found that prolonged fasting causes the body to deplete its glucose and fat reserves, forcing it into a detoxifying state that eliminates damaged cells and toxins.

When normal eating resumes, stem cells are activated, leading to the production of fresh, healthy white blood cells. This immune reboot effect was observed in both mice and humans, particularly in chemotherapy patients who showed improved immune health after fasting cycles.

Lead researcher Dr. Valter Longo explains that during fasting, a gene called PKA is suppressed—this gene must be turned off for stem cells to enter regenerative mode.

As a result, the immune system essentially clears out older, weaker components and rebuilds itself anew. While more research is needed to explore the full range of benefits across organs, the study suggests that fasting could be a powerful, drug-free strategy for enhancing immunity, especially for those with weakened systems due to aging or cancer treatment.

[IT Guy @T3chFalcon]

Anthropic the company whose entire pitch is "we're the careful, ethical, privacy-conscious AI lab, not like those other guys" has updated their privacy policy to say they can require ID scans and live facial selfies via a third party called Persona.

for context: Persona is the same verification vendor Discord tried to use for age checks, before backing off after a security researcher found their tech exposed on a government server.

so the most "we think about AI safety 24/7" company in the world picked the verification provider with main character energy in a surveillance scandal. incredible. love this timeline.

Very insightful — check Anthropic‘s updated privacy policy

[IT Guy @T3chFalcon]

The reason is quite hilarious 😂😂.

Microsoft put $50 billion into Anthropic.

FIFTY billion dollars.

they are a Project Glasswing partner. Fable 5 runs inside Azure. Microsoft sells Claude to its own enterprise customers through Microsoft 365 and GitHub Copilot.

and they won't let their own employees use it.

here's why.

under Anthropic's new Mythos-class data retention policy, every prompt you type and every response you get is stored for 30 days. automatically. no opt out.

if their safety classifiers flag anything in your session, anything, they keep it for up to two years.

you don't get told when that happens, what was flagged or who can see it.

Microsoft employees paste confidential contracts into these things. customer data. internal roadmaps. acquisition strategies. legal documents. source code.

all of it sitting on Anthropic's servers for 30 days minimum. flagged sessions for two years.

so the company that invested $50 billion looked at that policy and told its staff: actually hold on.

other Claude models still work internally. under Zero Data Retention rules. the normal ones are fine.

just not the most powerful one they helped fund.

and one more thing.

the Pentagon listed Anthropic as a supply chain risk in March and banned defense contractors from using its products.

Microsoft funds Anthropic. sells Anthropic's models. runs them on Azure. helped build the most powerful one.

won't let employees use it.

the Pentagon won't let defense contractors near it.

the safeguard that makes Fable 5 safe enough to release publicly is the same safeguard that lets Anthropic keep your data for two years.

the guardrail is a data retention policy.

but you can use it. it's in your browser right now. 🌚

have fun.

NEW: malware developers added nuclear & biological weapons text to to their spyware.

Goal? To trigger LLM safety refusals... so that their spyware wouldn't be analyzed by an AI security scanner.

Cleanest practical example I can think of for why over-indexing on first order safety alignment is risky.

When closed (and open) models ship with aggressive refusals, they will be sprinkled with second-order blindspots that attackers will discover...and exploit.

We are only in the earliest days of attackers leveraging these features, and it wouldn't surprise me if users systems that need to handle complex cybersecurity issues demand that models be less safety-blunted.

In the weeds: @SocketSecurity's post also shows why intention matters in how you design a malware analysis pipeline to avoid prompt manipulation.
