It’s technically nothing new. High-power, long-range PoE links have been a thing for a while. There’s still plenty of voltage drop. These are essentially high-powered switches designed for long-range links if need be. What’s cool is, with such high-powered ports, a bunch of their high-end commercial PoE PTZ cameras can be easily installed with dedicated links or branched off with flex switches. Now I need one. Fml.
Introducing: Long-Range PoE Switching
Power remote devices up to 800m away over a single Ethernet cable when paired with the required Long-Range Endpoint.
🔹 8 PoE+++ ports, 90W ea.
🔹 IPX5-rated outdoor endpoint with built-in surge protection.

Do you even mine, bro?

A biological attack is planned for Saturday
600 million pounds of sugar laced with synthetic chemicals will enter the bodies of our children.
Wreaking metabolic havoc, injuring vascular architecture, acidifying oral lining, releasing bacterial toxins, and blunting neural reward pathways.
Instructing that gluttonous consumption of poison is celebratory.

i’ll do everything in my power on the technical side to help this initiative move forward and navigate any protocol-level obstacles along the way.
on a personal note, Alex has a rare mix of technical depth, bizdev talent and deep Kaspa knowledge. i honestly can’t think of anyone better suited to lead it, and i really appreciate him taking this on

ASUS is releasing urgent updates for some of its Wi-Fi 7 routers after serious security flaws were discovered.
The vulnerabilities could allow hackers to gain control of an affected router and run their own commands.
One of the flaws is rated 9.4/10, or Critical, because it can potentially be exploited using a specially created VPN configuration file.
ASUS has released fixes for affected models, including the RT-BE88U and RT-BE92U.
If you have an ASUS Wi-Fi 7 router, check for a firmware update and install the latest version for your model.

Bend, Oregon man who shot and killed a shooter at his daughters' school speaks out, praises female teacher for fighting the shooter, allowing him to have a clear shot.
Kaylub Giamanco says he is haunted by the sound of children pleading for their lives.
He also praised the teacher for grabbing the gunman's weapon, allowing him to take a shot at the shooter.
"I want to recognize [the teacher]. She gave me the opportunity to make my shot without losing my life..."
"I swung the door open, and I stepped in, and I fired, and they dropped to the ground... I looked down at the gunman, and he was scrambling for his weapon. And I looked at him, and I shot him 2 more times..."

Dear @nvidia, a friendly ask from a guy running 4 of your 3090s and 1 of 3080 Ti.
The 30 series is 6 years old. You dont make these cards anymore. Maybe its time to hand them over to the community completely.
My post about unlocking the 3090 got 270K views in a day, and the replies are the real story. People asking about the 4090, 3080, 3060 and 2080 Ti. People asking how to do it on Windows. Others listing what the community already patches on these cards: the NVENC session limit, P2P between GPUs.
Thousands of people are digging through your old cards with kernel modules, 1 setting at a time, because they love this hardware and want everything it can give.
Publish what is limited on consumer Ampere and Turing. Ship an official driver switch for older generations. Or just open it up.
I understand the business side. Some people might keep their old cards longer instead of buying new ones. But it would be a huge gesture. You talk about local AI on stage, you ship open models, you sell DGX Spark for home. This would show the care goes all the way down to a used 3090 under someone’s desk.
Give them to us. We will do the rest: benchmarks, guides, models tuned for these cards.
@NVIDIAAI
NVIDIA sold millions of 3090s with 50% of the tensor speed switched off. Not missing. Switched off.
1 kernel module flips it to full, and my BF16 tensor pipe went from 82 to 155 TFLOPS. Nothing else changed on the cards, and the outputs match the stock run byte for byte.
All so the gaming card wouldnt eat into workstation sales. Every 3090 owner ran at 50% for 6 years, so a pro card could look worth the price. Fine, its their business model.
And LLMs are the least interesting place for this. Decode waits on memory, and my engine runs its experts in int8. Still +10% on prefill.
The models that live on BF16 tensor math are everything else. Qwen Image 2.1 and FLUX 3 Klein, where every diffusion step is big matmuls. MiniMax H3, which takes 4 to 7 minutes on my cards. Music and speech models. And training, every LoRA anyone ever trained on a 3090 went through exactly the path that was cut.
Thats what I measure next. This is only the start.
Nobody call me. Just shut it down till later.
Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance.
Proof of work relies on miners. A network forcing miners to front power, hardware, and infrastructure for a year will fail. That’s not how this business works. 45 days was extreme but acceptable if paid within 60 days, per traditional NET 30/60/90 terms. Claiming we or the developers do this for anything but fiat is wrong. These developers and maxis pay internet bills, send their wives to Costco, and donate to church in dollars. None of this works if you can’t keep the lights on or send kids to school. Nobody wants BTC, not even a fake improvement, regardless of spam. BTC is old, outdated, slow, and expensive to produce. It’s not for mainstream use. kaspa:native is the PoW closest to the ethos these plebs dream of. They’re stuck in the same boat as BTC, whose only path to success is the Lightning Network—a Layer 2 crutch, not Layer 1 PoW, that centralizes efforts further into oblivion with SHA-256 BTC that you loathe.

JUST IN: Elon Musk unveils the Tesla Roadster by launching it off a ramp before the car flipped in midair and safely landed on the ground.
The car is a collaboration between Tesla and SpaceX.
One of the most insane things I've ever seen.
California had lost the plot a while ago.

if you're living in california, it's very important that you vote against the state's abolition of private property this november. excerpt from our california voter guide for people who aren't insane:
Prop 40 // One-Time Wealth Tax for State-Funded Healthcare, Education, and Food Assistance Programs Initiative
No. Well, it’s time to talk about the “wealth tax.” Look, we’re not going to mince words here, if this thing passes it will be the end of our state. The “wealth tax” is our AI apocalypse. This is our Doom.
We’ve been writing about this thing for a year now. A very, very, very long story short: the state’s largest healthcare union wants to launch a new kind of tax, which we have never before seen in the history of this country, which would assess the total net worth of all billionaires in the state, and then seize five percent.
This is not an income tax. This is not a tax on an opt-in purchase of a finite resource (land) used to service that purchase with public resources. This is an inescapable, unavoidable seizing of property unlike anything we have ever seen.
Vote no. Vote no as if your life depended on it. This is not a simple matter of disagreement. If you meet someone in the real world supporting this, they are a bad person. Please tell them.
Steam games can drain your wallets via malware. The safer way to hold self-custody is in a clean computer, not one you just bought. A formatted and clean, windows only installer, fresh computer. A step further would be to host/build your own server and run separate VMs for each software-native wallet. I’ve was gifted 3 ledger wallets over the years and never once felt they were safe. I sold them all and never regretted it. I would never get a tangem or trezor either.
