Dear The French People, We don’t want you to be able to see how bad things have gotten at home. Sincerely, Your Dear Leader
Just in: France's Prime Minister asked telecom companies to prepare to block social media platforms. "I wish to have the ability to temporarily suspend access to these services in case of a repeat of urban violence," he wrote. @blast news broke the story.

Best hire ever at the EF, saying what needed to be said and heard for a decade. Protect this guy at all costs.
look the foundational problem with ethereum protocol design is that most of the people designing the protocol don't actually use ethereum themselves. you can't fix the right things if you don't use your own fucking product. you don't have enough skin in the game if you don't personally depend on the system you're designing & stand to lose money when it breaks. i understand, everything looks great from an ivory tower lol. things look very different when you're actually on the ground dealing with the consequences. if you don't use ethereum yourself but still think you're qualified to design its protocol, you're playing god with a system you don't have to live with and whose consequences you don't have to suffer.

Selected tweets from the past four years, translated from Hebrew: an ordinary Israeli citizen’s portrait of the Netanyahu regime. Preserved for my children and future generations, so that what happened here (and who was responsible) is never forgotten.

All smart contracts can be perfectly reverse engineered now There is no security by obscurity anymore github.com/lalalune/daosfun-…

Is this a world first in political campaigning? Naftali Bennett is inviting Israelis to add him to their family WhatsApp groups to personally convince them just before the vote. The campaign says it’s really him, not an AI bot or campaign staff. Has this been done anywhere?
האחיינית שוקלת להצביע לבן גביר? סבא עדיין מתלבט למי להצביע? צרפו אותי לקבוצת הואטסאפ המשפחתית ואשכנע את כולם להצביע לי. לא עוצרים עד שמשכנעים את כולם!

I am releasing my full documentary titled: Paris 3 Days Later... I dropped everything to go to Paris because it was clear from the footage that this is could be coming to America next. I couldn't believe my eyes, just burned up upside down cars lying on the street. The crazier part was just seeing people walk around it like it was nothing. In the video you'll see interviews I did with an anarchist and a communist that justified the riots. You'll hear from a woman who feels unsafe going home after work every night. Most of all you'll actually see that the majority of the people in the city do not want their city to burn. I will continue my reporting here and be at the next riot. The best way to support my reporting is to subscribe on X.

Imagine you wake up and: - PHP has two critical vulnerabilities, rated 9.2, and exploitation has already started, even before the fix was published. There's not fix for old versions... cybersecuritynews.com/php-ea… - Node.js has four high vulnerabilities, including arbitrary code execution. nodejs.org/en/blog/vulnerabi… - Eight TLS intermediates have private keys of 3 to 8 bits. I don't believe in conspiracy theories, but... arstechnica.com/security/202… All of this is in the field. Millions of machines are vulnerable. Most of them will not be patched in the near future and you can't really trust TLS anymore... The state of security is really, really frightening. And it won't get better anytime soon. 🫠

so I'm going to tell you a secret our team actually cares an absurd amount about building private money without backdoors if that means we have to keep out the terrorists, so we can have privacy for the good guys, so be it we're cypherpunks, not anarchists 🫡

My entire Israeli feed is photos from Ben Gurion airport & posts like this of Israelis traveling half way across the world to vote. I have family & friends coming in from SF, NY, Michigan, London, Barcelona, Lisbon, Berlin & Melbourne just to vote Bibi out. We’re about to justify the Israeli anthem & bring hope back! The next week is about what kind of Israel Israelis choose, a corrupt messianistic state in the shape of Ben Gvir or a liberal democracy that makes mistakes & tries to correct them so as to provide its citizens (all of them) a safe & sane country that’s a part of the west. For the geeks. The estimates were that 60,000 ppl would fly in (that’s 2 seats in knesset), but based on how full the flights are we could be near 100,000 Israelis flying in for the elections.
Replying to @klaiman14
Batel Blaish sultanik “I'm writing to you from the jet bridge in New York, a moment before they ask us to switch to airplane mode. Next to me stands a guy with a croissant-shaped neck pillow, and they just announced that our flight to Tel Aviv is running a little late. Turns out he's on his way to the polls too. The pillow is for the flight, the jet lag is for democracy. I left behind four little kids and a partner on crutches, who walked me to the front door this morning. I'm flying eleven hours just to walk into an elementary school classroom, stand behind a slightly crooked cardboard screen, and slip a small ballot into an envelope. I'm here thanks to AID Coalition’s Fly&Vote initiative, and the crazy part is that I'm really not alone in this. Tens of thousands of Israelis around the world are packing their carry-ons right now and crossing oceans. We could easily have said, "We're far away, let someone else worry about it." But the truth is, this is our home, and we have a say in its future too. 36J. I'm seated, we're taxiing, and the plane is full of Israelis on their way to the polls. To my right, Dotan from Atlanta. A row behind me, Adar from Austin. Ravit from Miami is in Economy Plus. And to my left, Mori, 70, from Hod Hasharon, who's still debating whether to go vote at all. So from my cramped seat, I'm asking you, with all the love in the world: if we're willing to fly halfway around the world to vote, won't you make the five-minute walk to the polling station? The short trip down the stairs of your building? I know, Election Day is a day off. There's the beach, there's the barbecue, and there's that couch in the living room, with the dip that knows the exact shape of your back. But the couch will wait. The beach will wait too. The polls are open for just one day. And it truly doesn't matter who you vote for. Right, left, center, everyone has their own truth. What matters is that you don't give up your right to make a difference, because whoever stays on the couch is simply letting others decide for them. Yours, your mom's, the upstairs neighbor's: every vote counts. Democracy goes on all year long, but it starts right there, behind the screen. On Election Day, have your coffee, grab your ID and the people you love, and go vote. And think of us, standing in line with you, jet-lagged (plus one guy with a croissant pillow). See you at the polls! P.S. By the time the flight attendants cleared the dinner trays, Mori had already promised she’d go vote.

This is how banks are planning to stop those "agentic bank runs." Watch closely: their business model depends on seeding this narrative that AI agents are dangerous. Remember, an "agentic bank run" (coined by Apollo) means agents helping customers move their own money en masse to higher-yielding products. Once agents are ubiquitous, there are only a few ways for banks to hold onto cheap retail deposits. Option A: Raise APYs (lol no) Option B: Reduce leverage via fewer loans (no fun) Option C: Ban AI agents, claiming they are a security risk (ding ding ding) Cloud agents like Muse and Dot are trivial to stop, since they come from Meta / OAI IP ranges. If JPM sends them a cease and desist, they will comply. Why would JPM bother? Because their business model depends on it; a huge portion of their ROE comes from cheap retail deposits. This is not theoretical. Just like Amazon banned Muse from shopping there to protect their ad revenue, JPM and Schwab have already banned AI agents to protect sticky deposits. Are agents perfectly reliable today? Of course not. But look at the fix they chose. Not "here's a safe API for agents," it's "no agents ever." That tells you they're not protecting customers, they're protecting themselves. No company ever wins a technological revolution this way. It's the last gasp of a dying business model. It's like the retailers who refused to put their inventory online and demanded users walk into the storefront. Over time they will lose market share to those platforms that embrace what's coming. Their whole deposit franchise depends on users unthinkingly clicking through walls of T&Cs and accepting 0.2% when the risk free rate is closer to 4%. Agents read the fine print and do their research, even when humans don't. For users, the answer is simple: local AI agent frameworks like Hermes, that will actually act on your behalf and that the banks can't block. As the article says, if the agent is running on your own computer, they can't actually tell it's not you.
SCOOP: Major U.S. banks are detecting unauthorized third-party AI agents inside customer accounts, including some attempting to take actions that appear to be independent of user instructions, sources told Axios. The findings have alarmed banking executives, who are racing to restrict access to their systems as AI moves at a velocity faster than financial institutions can respond, multiple industry and bank executives told Axios. Several banks are now preparing for worst-case and even “day after” scenarios, including how to rapidly secure or restore customer accounts if things go wrong, the people said. Several bank executives told Axios they're struggling to distinguish between human users and AI agents. One executive said banks also struggle to determine whether agents are authorized by customers or potentially operating without their permission, more akin to rogue agent behavior. Read my latest for Axios here: axios.com/2026/10/22/ai-agen…
