BREAKING: The US has bombed Tehran’s main refinery and burning oil is now flooding down the streets into the city’s sewers.

This is a vision from hell, unleashed by the US tonight.

Our hearts are with the people of Tehran, Beirut, and Gaza as they survive unprecedented violence at scale.
US and Israeli warfare, powered by AI-assisted mass targeting systems, has further turned urban centers into testing grounds for algorithmic carnage. We’re seeing the results.

Unplugging a Nation: Iranian Digital Workarounds in the Face of Total Blackout When the State plunged Iran into darkness, cutting the web, texts, and even landlines, Iranians leaned on a hard-won toolkit. Decades-old tactics are now encoded into the digital front.

Authoritarians can’t win when people refuse to be erased.
In #IranProtests, people built their own internet — #MeshNetworks, email relays, smuggled access, diaspora bandwidth, stealthy features, & IRL stealth.
Even in total comms blackout, every barrier met an instinctual workaround.

Super fascinating for cryptographers - some of the attacks out there are beyond what we could imagine

“Every participant who was detained by authorities & had biometrics enabled, said they were violently forced to unlock their phone. […]”
The research is clear: those with biometrics lost the power to resist device searches. Only using passcodes had some ability to refuse, delay, or obscure access.

A GKR Tutorial

Great blog by @vitalik.ca
exploring how to efficiently prove Poseidon hashes using GKR.
Love the shoutout to multilinear polynomial commitment schemes like Basefold for added efficiency

one more election thing this morning: because New York is large, people might lose sight of the Mamdani victory being local politics. but it is, and it points up the potential of local politics to reshape direction, to inspire broadly, to change the story

Our struggles are connected: Palestinians, migrants in LA, families in Tehran, queer folks in Cairo, or Sudanese refugees. The decentered are policed, surveilled, criminalized. Same tools. Same logic. Different uniforms. Identify the decentered, expose the system, break its power. 🔏 1/3

This is the same admin that violently fearmongers about "foreign threats" & boasts abt pouring billions into “advanced tech” for "national security." Subscribe to @micahflee.com and see how the Israeli chat app used by Trump officials was hacked within 15 mins. bsky.app/profile/jose...

As immigration controls are violently targeting pro #Palestine students & other migrants, their low-tech tactics remain the most dangerous & authoritarian, Afsaneh Rigot writes.“The oppressed know the oppressor better than it knows itself.” We can outsmart them. the-decenter.ghost.io/dehumanized-...

Just updated a result on eprint (2024/1843), improving the query complexity of the BaseFold IOP, while maintaining small soundness error. Also relevant for improving the communication complexity of coding-based SNARKs

I have work to do but I'm distracted by watching US scientific progress & leadership being irreversibly undermined because a few unelected malcontents are penalizing researchers for following legal requirements set out by congressional orders to augment basic research with benefits to society.
