They're also up to their eyeballs in pre-IPO AI equity & need retail investors to provide exit liquidity when those companies go public.
Hard to unload your overpriced AI bags on retail when BTC is starting another bull run.

‼️ Anthropic and Google researchers found a flaw that lets one crafted packet hijack a server during network boot, before Secure Boot checks the OS.
Almost all servers on earth are affected.
CVE-2026-97631 sits in TianoCore EDK II, code in the UEFI firmware of most servers.
Readers added context they thought people might want to know
The vulnerability is limited to servers actively PXE network-booting with vulnerable EDK II firmware; most servers boot from local disks and are unaffected in normal use, with Intel noting limited impact on supported products.

Bitcoin will never break its all-time high again." — Jason Calacanis
Jason, I'll bet you $1,000,000 it will break its ATH. Here are the terms:
Bitcoin hits or exceeds $126,210.50 on or before October 28, 2028, 12PM PST
I’m happy to trust you to pay or if you prefer we can each escrow the dollars with independent party.
The bet is either settled when Bitcoin hits the ATH or on October 28, 2028.
@jason Do we have a bet?
Sean Walters retweeted
Guys, @Jason is literally a professional engagement farmer.
That's his full time job of the past thirty years, since his Silicon Alley Reporter days.
Just enjoy the absurdity and have fun dunking on him if you like
There's zero signal involved, and he's completely aware of it.

Chamath’s Bitcoin that he sold is worth more than his entire net worth is now
Of course he’s bitter and retarded about it

Experimental releases of GrapheneOS with our initial port to the Linux 6.18 branch are now available for testing on the Pixel 10, Pixel 10 Pro, Pixel 10 Pro XL and Pixel 10 Pro Fold. We've done initial testing but there will likely be at least a dozen more crashes and other issues to find and fix.
People should only help with testing this if they're able to tolerate regular kernel panics and various hardware functionality not working. We've done basic testing of Wi-Fi, Bluetooth, cellular, GNSS, Vulkan and virtual machines via the Terminal app and microdroid API but there's far more to test.
If you're interested in helping with testing, please join either our #testing:grapheneos.org channel on Matrix or #testing on our Discord server. We've posted links to over-the-air updates for each of the 4 releases in both channels. These are production builds signed with the official signing keys.
Users can update to these from our current releases and update from those to future experimental and regular releases. Hardware functionality should be the focus. Bluetooth / BLE, NFC, assorted Wi-Fi APs / standards, DisplayPort alt mode, USB peripherals, USB host modes, GNSS and NFC are examples.
These experimental releases have all of the changes from our current development branch and are security preview releases with the security preview patches from our previous release. We have 4 official build machines so we can build for all 4 devices in parallel and make new releases as people test.
Do not install the experimental releases unless you can tolerate regular freezes, kernel panics and broken hardware functionality. These are highly experimental and you should not expect the device to be very usable during the early testing. We'll make new releases with fixes for discovered issues.

Announcing 3 Critical vulns for hundreds of millions of IoT, Firewalls, OT, and Military devices including: Palo Alto Networks, Comcast, D-Link, HP, Canon, Honeywell, GE, Oracle, Siemens, Rockwell, Digi, Lockheed Martin, Boeing...
The vulns are with GoAhead Web Server which is a backend library used by these devices. There's a patch available from GoAhead but that doesn't mean there's a patch available for the devices yet -- that's up to the manufacturer.
- TLS traffic over DHE ciphers have a 1-byte secret, "04", meaning anyone can decrypt connections to these devices and steal login credentials and session tokens if the client negotiated with DHE ciphers like the latest TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256, which is extremely likely.
- LibreSSL mTLS has been completely bypassed, meaning anyone can connect over mTLS. If you have one of these devices listening on the internet and are expecting mTLS to protect it from attackers, take it offline or patch asap.
- OpenSSL Certificate Revocation Lists (CRLs) are not enforced, meaning if a user device is stolen or compromised, and you revoke that mTLS cert, nothing actually happens. There are a lot of other attacks this can be used for.
These are critical because these types of devices run our world. Water systems, electricity, military, firewalls, critical infrastructure.

Trace Mayer’s annual #ProofOfKeys day was a brilliant idea, a holiday that should've united both plebs and institutions
Too bad nobody talks about it anymore. One day you're gonna find out the hard way that Coinbase marked the same 11,000 coins to 40 different treasury companies
A Bitcoin treasury company (@Datavault_ai $DVLT) just crashed because they informed investors that they haven't been able to withdraw BTC from the exchange (@BiconomyCom) that is holding all their treasury funds after 4 months of transfer requests.

Coinbase lost customer data and calls it a vendor incident. A shipping partner at least gets your order to your door. An analytics vendor means nothing to you, the customer. @coinbase chose to hand over that data, so it's their own fault. Another reason to hold your own keys.
Coinbase has not had a data breach.
Amplitude, an analytics vendor, experienced a security incident which impacted a small subset of Coinbase customer contact data, among other Amplitude customers.
We’ve found no evidence of unauthorized access to Coinbase systems, and customer funds were not impacted.
We are notifying impacted customers and regulatory agencies in accordance with our legal obligations.

here's my AI cybersecurity apocalypse white pill.
I've been fixing bugs in leftover human code non-stop for over a year now. literally cleaning up years of human slop.
at the same time, i've been building fully AI-written complex software which I regularly review with AI the same way that I'm reviewing the human code.
the difference is like day and night. good models don't just find the bugs, they also produce far fewer bugs.
the difference between a big project written exclusively by modern frontier models and one written by a dozen engineers is just incredible.
all those little obscure mistakes that humans overlook are mostly absent. if you take care of your project, the code quality can be great and there's almost no accumulation of weird edge cases that sneak in inevitably over the course of multiple years of working on a code base with a team of humans.
makes me very optimistic about the future.

Some people who plan to disappear into the woods better figure out how to evade LiDAR.
Some people is me.
Purdue University's IDEAS Lab built an autonomous drone that tracks runners through dense forests completely without GPS or cloud networks.
By running 3D LiDAR mapping and obstacle-avoidance AI entirely on-chip, it can weave under tree canopies and predict target movement through blind spots in real time.
Massive implications for next-gen search & rescue and edge AI.

Steak 'n Shake is giving hourly workers 21¢ in Bitcoin per hour. Inflation already ate ~20¢ of purchasing power for a $14/hr worker since March, but that Bitcoin is now worth ~26¢.
Bitcoin is quietly defending the purchasing power of American workers. partners.wsj.com/the-nakamot…

A hacker is actively attempting to breach the US Federal Election Commission's systems, forcing the agency to temporarily shut down all web-facing services one week before midterms, according to an email reviewed by Reuters.
The FEC confirmed its electronic filing system is currently offline and IT staff are working to restore service. The agency's website remains down.
While the FEC regulates campaign funding and enforces campaign finance law, it does not administer elections. Elections are run at the state level.

Code-execution flaw in UEFI firmware threatens most servers on planet Earth arstechnica.com/security/202…
Readers added context they thought people might want to know
The vulnerability (CVE-2026-97631) only affects systems actively PXE network-booting using vulnerable EDK2 firmware; it requires sending malicious ICMP packets during that window and does not impact systems booting from local disks or with PXE disabled.
