Stategically, $INTC is the most valuable businessi. the US right now. And it is not even close.

FYI: 5.6 Sol medium is better than 5.5 xhigh. As you go higher in reasoning levels on Sol, you will get insane levels of performance, but can burn through limits much more rapidly. We’re working on communicating this better!

We're extending access to Claude Fable 5 on all paid plans through July 12.

For years, people assumed pulling the power plug instantly erased everything in RAM. It doesn't. That simple assumption led to one of the most influential hardware security papers ever published: Cold Boot Attacks. The key observation was that DRAM doesn't lose its contents immediately after power is removed. It stores data as electrical charge in tiny capacitors, and those charges leak away gradually. At room temperature, memory can retain data for several seconds. Cool the DIMMs, and that window can extend significantly. Researchers showed that an attacker with physical access could exploit this behavior by quickly rebooting a machine into a small custom OS or even transplanting the DIMMs into another compatible system, and dumping memory before the contents fully decayed. Why is that useful? Because RAM often contains things you never want an attacker to see: • AES disk encryption keys • RSA private keys • Kernel secrets • User credentials • Session keys The clever part wasn't just dumping memory. Even after some bits had decayed, the researchers developed reconstruction techniques that recovered valid cryptographic keys from imperfect memory images. They successfully demonstrated attacks against systems using BitLocker, FileVault, dm-crypt, and TrueCrypt (in configurations where the encryption keys were already resident in RAM). The paper changed an important security assumption. The cryptography wasn't broken. The operating system wasn't broken. The weakness came from a physical property of DRAM itself. It's a reminder that computer security isn't just about software bugs or weak algorithms. Sometimes, the behavior of the hardware underneath becomes part of the attack surface.
