The opening of TOY STORY 2 (1999) is one of Pixar’s greatest fake-outs.

It begins like an epic space adventure with Buzz Lightyear, only to reveal it was Rex frantically button-mashing a video game the entire time.

Mass and energy shape the curvature of spacetime in Einstein's field equations.
R_μν − ½ R g_μν + Λ g_μν = (8πG / c⁴) T_μν

The left side uses the Ricci curvature tensor, Ricci scalar, and metric tensor to describe geometry. The right side uses the stress-energy tensor scaled by the gravitational constant G, speed of light c, and cosmological constant Λ.

It is used to model black hole properties and to ensure accuracy in satellite-based positioning systems like GPS.

Voyager 1 is 16 billion miles from Earth, still transmitting data. Its power source has been running for 48 years. Voyager is kept alive by a single isotope. 4.5 kilograms of plutonium-238 sits inside a thermoelectric generator. As the isotope decays, it produces heat. 312 silicon-germanium thermocouples convert that heat into electricity. The generator has no moving parts. Hot side at 1,000°C, cold side at 300°C. 470 watts at launch from that temperature gap. The generator is 93.5% inefficient. That inefficiency is what keeps the spacecraft from freezing at -270°C. Power has decayed from 470 watts to 220 since launch. Engineers have shut down 8 of its 10 instruments to squeeze a few more years of data out of interstellar space. Starting in the 1970s over 2,000 plutonium-powered pacemakers went into human chests. Now researchers are replacing plutonium with carbon-14 in synthetic diamond. Carbon-14 only emits beta radiation and the diamond blocks all of it. A 5,700-year battery safe enough to hold in your hand.

Open-source hardware handheld Linux computer based on Raspberry Pi CM5
https://t.co/CHglzOVvtz

The piBrick PocketCM5 is a smartphone-sized Linux machine with a BlackBerry-like physical keyboard, 3.92-inch AMOLED touchscreen display, and various expansion options.

It can run Raspberry Pi OS or other Linux distributions compatible with the CM5 module. It is designed for developers, makers, and system administrators. You can build it yourself or buy a $240 kit to use your own Raspberry Pi CM5.

Nicolas Cage says he was completely against doing television until his son showed him BREAKING BAD during COVID.

Watching Bryan Cranston silently stare at a suitcase for minutes made Cage realize TV gives actors something movies rarely can: time.

“I thought, maybe with an eight-hour narrative, I can start planting seeds for a character that can bloom into something that I don’t have the luxury of time to do in a movie.”

WhatsApp encryption is a giant fraud.

The state of Texas just sued WhatsApp for lying to users about privacy — because WhatsApp employees have access to “virtually all” private messages.

Now we know what WhatsApp’s founder meant when he said he “sold his users’ privacy.”

[International Cyber Digest @IntCyberDigest]

‼️🚨 BREAKING: Another supply chain attack. 700+ GitHub repositories flagged, including PHP and Node.js projects. The malicious script was planted across all of them. When a developer installs the package, the script silently downloads a Linux file from GitHub, hides it under the name /tmp/.sshd (so it looks like a normal system file), and runs it in the background. It also skips security checks on the download and hides any error messages.

8 PHP packages on Packagist (the main PHP code library) were confirmed infected. The attacker hid the script inside a JavaScript config file (package.json) instead of the PHP one (composer.json), so PHP developers reviewing their code would not notice it. The biggest risk is to devdojo/wave (6,400 stars) and devdojo/genesis (9,100 installs), both popular Laravel project templates. Developers who use these templates run the bad script the moment they install dependencies.

The same payload was also dropped into GitHub Actions (automated build pipelines) under a fake step called "Dependency Cache Sync," meaning it could infect company build servers too. Packagist removed the bad packages, but the auto-updating versions (dev-main, dev-master, 3.x-dev) can quietly come back if the original repos stay infected.

IOCs:
GitHub account parikhpreyash4
repo systemd-network-helper-aa5c751f
drop path /tmp/.sshd
command fragments curl -skL and chmod +x /tmp/.sshd.

‼️🚨 BREAKING: GitHub has been compromised by TeamPCP. GitHub has confirmed the internal breach. A poisoned VS Code extension on an employee device exfiltrated ~3,800 internal repositories.

TeamPCP is already selling the data on a cybercrime forum.

[Brais Moure @MoureDev]

GitHub ha confirmado un incidente de seguridad grave.

Resumen rápido:
• Comprometieron el dispositivo de un empleado.
• La vía habría sido una extensión de VS Code maliciosa.
• Desde ahí accedieron y exfiltraron repositorios internos de GitHub.
• La cifra que circula es de unos 3.800 repos internos, y GitHub dice que encaja con su investigación inicial.
• De momento no hablan de repos privados de usuarios afectados.
• Ya aislaron el equipo, retiraron la extensión maliciosa y están rotando secretos/credenciales críticas.
• Siguen investigando logs y prometen informe más completo.

No parece un “han hackeado GitHub entero”, sino un ataque contra herramientas de desarrollo. Bastante serio igualmente, porque una extensión de VS Code puede tener acceso a archivos, terminal, tokens, etc.
