We need to normalize multifactor for every saas service. Why isn’t this a priority? Seems like such an easy feature.

If you’re the founder of a company operating at reasonable scale and you’re not actively planning to spend >$100k to try to hack yourself in the next 30 days using agent swarms
I beg you to reconsider
DMs open if you want to chat
shit is crazy. stay safe out there fam

Just in case any builders are wondering
@multicoin has no interest in expanding the mandate and we will continue spending 100% of our time and capital on crypto and blockchain markets
our DMs are open if that interests you

What would Solana’s consensus look like in a post-quantum world?
Meet Quantumglow: a proposed adaptation of Alpenglow that aims to protect consensus while preserving fast finality.
@jacobvcreech and @qkniep explain how it works. Full video below👇

I used this treatment last year and my tinnitus is basically gone.
A groundbreaking treatment pairing auditory tones with mild electrical shocks rewires the brain to quiet chronic tinnitus.
Chronic tinnitus, the agonizing perception of ringing in the ears without an external sound source, affects millions worldwide and has long eluded effective medical intervention.
However, innovative research in neuroscience shows that bimodal neuromodulation—a technique combining audio tones with gentle electrical stimulation delivered directly to the tongue—can effectively quiet these phantom sounds.
By stimulating touch receptors on the tongue while simultaneously playing targeted acoustic signals through headphones, the treatment leverages the brain's natural neuroplasticity. This dual-sensory approach encourages the central nervous system to reframe its sensory processing, essentially retraining the brain to ignore hyperactive auditory signals.
In a landmark clinical study involving over 300 adults suffering from chronic subjective tinnitus, more than 86% of compliant participants experienced a significant reduction in symptom severity following 12 weeks of daily treatment.
Remarkably, these therapeutic benefits persisted for up to 12 months post-treatment, representing a major leap forward in long-term tinnitus care. Described by patients as feeling like a mild fizzing sensation on the tongue, this non-invasive therapy offers a promising and safe alternative to traditional management strategies, bringing renewed hope to millions seeking lasting relief.

The GENIUS Act marks a watershed moment in American finance, further cementing the United States as the crypto capital of the world. Just as President Abraham Lincoln’s National Currency Act of 1863 established a national framework for bank-issued currency, the GENIUS Act establishes a federal framework for payment stablecoins in the digital age.
The @USOCC's final rule carries that landmark legislation forward, providing a clear, practical foundation for private-sector innovation, competition, and American leadership in digital assets.
The announcement we've been waiting for... Anthropic is about to drop their personal agent Duet (love the name)
A direct competitor to Dots, Grok Bot, Hark, and Muse
All powered by what I believe to be the best model on earth right now Opus 5.5
This is the one I'm anticipating the most. Claude more than any other AI has felt the BEST to talk to
It feels truly human and collaborative
This has been what's dearly missing from this new class of agent harnesses. None of them feel truly HUMAN
I have no doubt this will be the warmest, most fun personal agent to use
I truly believe this personal agent harness race is the most important race of them all. More important than the model race
People are giving their personal agents access to EVERYTHING
Their emails, calendars, text messages, finances, EVERYTHING
This is unbelievably valuable data people are now willing to give away to any company that makes helpful assistants
The winner of this harness race will have access to incredibly valuable data it can then use to train even better models
Anthropic is officially coming for the crown

Alpenglow is live! It's been a crazy grind over the past 20 months bringing this to mainnet.
Huge shoutout to the Anza engineering team, @TheWattenhofer and the research team, the Anza security team, all our auditors and bug bounty participants.
And of course the validator operators who spent countless hours with their own hardware to help us test and bring this to mainnet.
We couldn't have done this without you all! Lets AlpenGO.
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.
Have you ever seen a great white breach?

Not just PHP. Node.js has also announced security releases for October 21, with HIGH-severity vulnerabilities affecting its 26.x, 24.x and 22.x release lines.
If you run either stack in production, keep an eye on official advisories and apply patches promptly.
Security maintenance doesn't stop at your application code. Your runtime matters too.

New Delphi Podcast with Andrej Radonjic @0xdrej, founder of Grass
To a website, Grass looks like normal users browsing. Behind it is millions of opted in residential nodes and a data platform that has delivered exabytes of web data to the frontier labs
We get into how AI flipped the hard part of search upside down. The index used to be the moat, and crawling was free. Now AI tooling makes the index cheap, while AI crawlers have pushed the web into blocking everything. The hard part is getting the page at all
Training data is already a profitable business for Grass with most of the top labs and multiple Mag 7 companies as customers. Crawling for that data also means mapping the entire internet, which is what puts Grass in a position to build search on top of it. Contents API is live, Search is next, and multimodal grounding follows
