Normies don’t understand the difference in server RAM and desktop, yet find time to chime in for engagement baiting.
People crying over this are idiots. Clearly the RAM in a data center running full tilt 24/7/365 serving millions of people is better allocated than the RAM in your machine powering your Reddit browsing.
Readers added context they thought people might want to know
Sam Altman was specifically discussing local AI inference on personal computers versus cloud needs, not general use like web browsing. Cloud servers average ~13-22% memory utilization per analyses of major providers, not full tilt 24/7.

Binance is trash. Not because it didn't list Kaspa; because it didn't *use* Kaspa to protect its users funds. Kaspa with Covenants would have stopped this $6B breach.
Covenants allow to attach customized spending rules directly onto individual coins (UTXOs) enforced natively at the protocol level.
Instead of relying on a heavy, account-based virtual machine like Ethereum (EVM), Kaspa enforces these conditions natively at the protocol level.
Hot wallet operational risk just cost the industry $6B+.
Build systems where large movements are $KAS covenant constrained by default, enforced on the L1.
We’re looking for those founders for the KaspaBots accelerator.
Apply if you’re building the infra that makes “one compromised laptop” irrelevant.

OpenAI CEO Sam Altman says it’s “quite terrible” that people have so much DRAM sitting in their own PCs instead of being used in data centers.
“Everyone have a bunch of the world’s limited supply of DRAM sitting in their own computer. And be used 5% of the time,”
He argues that cloud data centers should make better use of limited memory supplies instead of people running AI models locally.

Binance's initial investigation suggests that the security incident may involve a compromised DevOps engineer’s laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions. We have found no evidence of any wallet private key leak. We will share a detailed technical post-mortem once the investigation is complete and the facts are fully verified.
The estimated total impact sits at around $6.3B. We have worked with blockchain partners to freeze affected assets, with ~$3 billion frozen on-chain so far.
Binance will cover all losses from the SAFU fund and the company’s funds. User funds are safe. We will also publish an updated Proof of Reserves once the remediation is complete.
As an immediate precaution, Binance has:
- temporarily suspended deposits and withdrawals while security checks are completed;
- revoked the affected address authorisation;
- engaged law enforcement and blockchain intelligence partners to trace and recover funds.
Our teams are working around the clock to resolve this issue safely and thoroughly. We are working closely with our law enforcement partners to confirm the identity of these criminals and bring them to justice.
Please rely only on official Binance channels for updates. Please feel free to contact Binance Customer Support if you have any further questions.

Oh no, BTC is falling. Must be those suits controlling the market. I heard it’s up and to the right only.
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.
