In dark times, our only hope is work-life balance.
Following the ongoing situation in Iran, I am convening a special Security College on Monday. For regional security and stability, it is of the utmost importance that there is no further escalation through Iran’s unjustified attacks on partners in the region.

Show me the outcome. If an executive at Patch bragged about their costs being up 66% *and* didn’t describe the associated impact - their things would be in a box before the end of the week.
Student funding in California is now a RECORD HIGH! Since Governor Newsom took office, it’s increased 66%— reaching $28,282 per student as the state makes historic investments in public education.

The best part of working with AI is that it's Christmas every week.

Introducing Claude Opus 4.7, our most capable Opus model yet. It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back. You can hand off your hardest work with less supervision.

Also English in the caption makes it clear this is for the world, not French nationals.
Say what you will about the current admin’s social strategy - allies are following suit. Cold War propagandists could never imagine.

I’ve gotten to the point where if I’m not redirecting or continuing to prompt claude/codex/opencode between meetings - I feel unproductive. Constant foreground and background work is a paradigm shift.

It's pretty remarkable how quickly we're seeing some of the knock on effects of a *potential* wealth tax in California. Brin, Thiel et al. all making moves. Imagine the capital flight if such a tax actually went to a vote or was actually ratified?
NEWS: Google co-founder Sergey Brin is cutting ties with California. In the 10 days before Christmas, an entity connected to Brin terminated or moved 15 California LLCs that oversee some of his business interests or investments out of the state. With @RMac18 @hknightsf.

Oldest American ally is officially with the program.
The Venezuelan people are today rid of Nicolás Maduro’s dictatorship and can only rejoice. By seizing power and trampling on fundamental freedoms, Nicolás Maduro gravely undermined the dignity of his own people. The upcoming transition must be peaceful, democratic, and respectful of the will of the Venezuelan people. We wish that President Edmundo González Urrutia, elected in 2024, can swiftly ensure this transition. I am currently exchanging with our partners in the region. France is fully mobilized and vigilant, including to ensure the safety of its nationals during these uncertain times.

Too many “years in review” and victory laps on the timeline. Not enough accountability on what didn’t get done in 2025.

why not just raise income tax rates? because your real intent is not to just “provide healthcare”. you’re masking that you are proposing the creation of, for the first time in the 250 years of this American republic, an organized government seizure of private property from citizens. you’re calling it a “wealth tax” or a “billionaires tax” or “millionaires tax” or whatever nom du jour polls well. but at the end of the day, it’s the seizure of private property from citizens by the government. citizens that earned money, paid their fair taxes on those earnings (53% if they live in California) and are now being told they need to hand over after-tax assets because the government has failed to provide promised services with the revenue it’s collected, and are now re-casting their own failure to be a socio-economic inequity that must be justly resolved... a slippery slope that has never gone anywhere good (see economic effects in USSR, Cuba, Venezuela, France and Norway wealth tax etc.) the American founders fled tyranny in Europe and this amazing nation was populated by immigrants (myself and your parents) from around the world not just looking for a “better life” but for a place where they could have freedom from tyrannical governments that can take what they want from private citizens. a great nation borne of property rights, the rule of law, and endowed freedoms to believe, speak, or act. these principles led to the greatest run of innovations, successes, and widespread increase in prosperity, for all citizens, ever seen. the citizens, the individuals, not the institutions, delivered this progress. those who invented, who toiled, who bled, who sacrificed, who took risk and persevered, who led, and who changed the world, are not charlatans, kleptocrats, or oligarchs. they’re what made us all better off. prosperity is a measure of america’s success, not its failure. it is your principle that is so offensive, as evidenced by the broad disdain for your flippant flirtation with the darkest of human fantasy - socialism. you and other neo-socialists have led so many of us to reflect on America’s history and what it is becoming. that now leads so many to consider, so unnecessarily, leaving their homes for a place where everyone stands up to shout down the principle you suggest. because if your ideas are now considered moderate, it’s clear this titanic is sinking. that a “simple tax” of taking assets that have been earned, through toil and tribulation, rightly taxed, and preserved, should now be unjustly seized, is your solution to a problem of obvious government mismanagement and outright fraud, tells us that your true motivation lies not in giving people healthcare but in cutting down success and deleting the system of prosperity and opportunity for all. i don’t care, and neither should anyone else, what the sum total market value of a private citizens private assets might be. it is none of my business and should be none of yours. because, again, once you open that pandora’s box, we might as well study Lord of the Flies … there is literally nothing stopping 51% of citizens demanding that their government go out and seize 100% of the private property of the 49%. want to give healthcare to people in need? do your job and fix healthcare. make it affordable. want to be lazy about it? then do your job lazily and raise income taxes. want to take private property from private citizens who have paid their fair share of taxes and legally earned their property, then honestly declare that it is envy, not inequity, that you strive to resolve…

The tech capital of the world will finally have AVs the moment you arrive. We’ve been back, but now we’re accelerating.
Waymo is coming to SFO! The airport has approved a pilot permit to begin autonomous rides. This rollout will happen in phases—and we’ll keep you updated every step of the way until anyone can request a @Waymo ride right from @flySFO.

My 21 townhouse HOA is about to get smoked on property and liability insurance this year. Price nearly doubled last year, trending toward growing another 30% this year. What do folks use? Potential alternatives we should consider?
