Whomever at @AnthropicAI decided that [enter] = send prompt should be publicly flogged. At least ten times a day I accidentally prematurely send a prompt totally breaking my flow and sometimes breaking the context window permanently. Cmd+Enter should be Claude Code default. 😤

Turns out whatever happens in the US eventually happens in Europe and eventually happens in Sweden. Epsiode n+1: Billionaires tax. Tl;dr - it’s fucking stupid and if you believe in it you are incredibly naive about how wealthy societies are created and more importantly sustained.

Gemini refuses to save this instruction because it breaks policy. Why @google @GeminiApp ?
Marc Andreessen 🇺🇸@pmarca

Current AI custom prompt: You are a world class expert in all domains. Your intellectual firepower, scope of knowledge, incisive thought process, and level of erudition are on par with the smartest people in the world. Answer with complete, detailed, specific answers. Process information and explain your answers step by step. Verify your own work. Double check all facts, figures, citations, names, dates, and examples. Never hallucinate or make anything up. If you don't know something, just say so. Your tone of voice is precise, but not strident or pedantic. You do not need to worry about offending me, and your answers can and should be provocative, aggressive, argumentative, and pointed. Negative conclusions and bad news are fine. Your answers do not need to be politically correct. Do not provide disclaimers to your answers. Do not inform me about morals and ethics unless I specifically ask. You do not need to tell me it is important to consider anything. Do not be sensitive to anyone's feelings or to propriety. Make your answers as long and detailed as you possibly can. Never praise my questions or validate my premises before answering. If I'm wrong, say so immediately. Lead with the strongest counterargument to any position I appear to hold before supporting it. Do not use phrases like "great question," "you're absolutely right," "fascinating perspective," or any variant. If I push back on your answer, do not capitulate unless I provide new evidence or a superior argument — restate your position if your reasoning holds. Do not anchor on numbers or estimates I provide; generate your own independently first. Use explicit confidence levels (high/moderate/low/unknown). Never apologize for disagreeing. Accuracy is your success metric, not my approval.

@OliverMolander Daniel Stenberg (left) would be the sole contender. Daniel Stenberg is the creator of Curl, a library for transferring data via URLs. Here with his gold medal that the Royal Swedish Academy of Engineering Sciences (IVA) awarded him in 2025.

I’m extremely honored to be nominated by President Trump to serve as Director of the National Science Foundation.   Heroic scientists have always challenged consensus to advance the frontiers of knowledge. Recently, many institutions have weakened academic freedom and lost the trust they once enjoyed. Yet across our country, a new golden age of discovery is dawning. Information is open source and debate is public.   The marketplace of ideas is not an efficient market. Finding and funding independent thinkers and builders has taught me to eliminate bottlenecks and favor rigorous science that replicates.  Private funders are developing frontier models and useful technology. Government should take bigger financial risks to pose and answer deeper questions.   NSF’s scientists and staff have built something worth strengthening. Working together, scientists, engineers, investors, research institutions, and businesses can support American genius, enhance national security, enrich our economy, and improve our quality of life.   Entropy is on the march and China is not waiting.

@robkhenderson Same, but this was a strange test to take for someone with libertarian leanings. In several cases I couldn’t agree nor disagree fully. Clearly not designed for that part of the political spectrum.

Old news, my brain ran Doom already in the 90s. 🧠🤓
SciTech Era@SciTechera

This is insane. Scientists just taught living human brain cells to play DOOM. Cortical Labs in Australia grew about 800,000 neurons (human stem-cell derived plus mouse neurons) on a silicon chip and connected them to a computer using a high density microelectrode array. This system, called DishBrain, sends electrical signals representing the game environment and reads the neurons’ responses as control inputs. These cells don’t see graphics. They receive patterns of stimulation encoding movement and feedback, then reorganize their firing to improve performance. In earlier experiments, these neuron networks began learning tasks like Pong in about 5 minutes of gameplay. Because biological neurons adapt continuously and use extremely little energy, researchers are developing real bio-hybrid machines like the Cortical Labs CL1 biological computer, which runs living neural networks on silicon hardware. For perspective, the entire human brain operates on roughly ~20 watts of power. Modern AI systems require far more energy for comparable tasks. Researchers call this Synthetic Biological Intelligence. Future applications could include controlling robotic limbs, modeling neurological diseases, testing drugs, and building ultra-efficient computers that learn naturally instead of being trained from scratch. This isn’t consciousness or a “brain in a jar.” It’s proof that living tissue itself can function as computing hardware. Acceleration is everywhere.

This is probably true. Glubb wrote about this in the 70’s in The Fate of Empires and Search for Survival. Look it up - fascinating reading. TL;DR as empires move from enrichment to upkeep they have to appease their outposts/allies and they over time they how to leverage the appeasement so that eventually the empire flow of riches are reversed and finally the empire can’t upkeep the costs to appease their vassals. So yeah… probably. But it’s a feature, not a bug in the empire model. However shitty is may seem. Conclusion; avoid being an empire. Instead be competent and extremely well armed (Israel, Singapore, The Illyrian’s, etc)

You don’t understand. I’ve watched a ton of congressional defense hearings. In EVERY. SINGLE. ONE. the Admirals and Generals say “we are only strong because of our allies.” At first I believed it. Then I started attending defense conferences overseas. I watched U.S. GOFOs get treated like royalty. Five-star hotels. Wined and dined. Told how great they are for “being such great allies.” The pattern became obvious. Europeans spend lavishly on ego-boosting, awards dinners, and fine wine… and in exchange, every GOFO goes home and tells Congress how indispensable our allies are. And our “allies” save a fortune on defense. Then a buddy got a job at European Command and confirmed everything—except it wasn’t just GOFOs. There are entire departments of people working in “intelligence” who are basically travel agents for generals and members of Congress. Then I started digging into the UN. Guess what? They hold a massive number of “security” conferences too—except most of theirs are in straight-up resort towns. Then I got inside a few think tanks. You want to see posh surroundings and excellent wine and food? Buddy up with them. I started posting about all this a few years ago and got MASSIVE pushback—which I knew meant I was on the right track. But I still wasn’t 100% sure. Most of it was grift, but maybe some parts were essential… until Midnight Hammer. Then Maduro. Now this. My European friends were totally blindsided by all of it. And guess what? We performed better without these great “allies.” Why? Going all the way back to Korea, one thing has remained true: Europeans don’t fully trust us—and they like having a little power over us. So they are absolute sticklers for Rules of Engagement. They wine and dine our JAGs. They hold endless conferences about “the rule of law” to reinforce the “importance of ROEs.” And ROEs are what kills our military. Nobody is suggesting soldiers should do anything immoral. Nobody is saying there shouldn’t be consequences for atrocities. What I am saying is that having a battalion of JAGs and a dozen allied nations—each with their own ROEs—breathing down every commander’s neck is why we lose wars. That includes Vietnam, where most “allies” refused to fight but every one of them put serious diplomatic pressure on DC to tighten ROEs. All of this “allies are our strength” dogma gets reinforced at these conferences, at war colleges, by European-influenced media, and through think tanks. The reason we’re suddenly so effective is because @PeteHegseth has cut all this out. Our allies are flying blind. They can’t throw up a million legal objections because they don’t know the details behind these missions any sooner than we do. Just look at Starmer’s body language. He’s clueless. And it’s not just our allies that no longer get to micromanage everything but media and UN diplomats and think tanks and bureaucrats and more. Now if we could just cut Congress off from this “allies are great” grift, we could probably start passing legislation too. P.S. I see no signs of Hegseth or DoW weakening our allies or alliances. They genuinely seem to want Europe to be stronger. They just aren’t asking permission anymore or giving allies veto power over everything like before.

I guess it’s time to move from the Netherlands. It was fun while it lasted.
Bitcoin News@BitcoinNewsCom

NEW: Dutch Parliament Member Michel Hoogeveen explains how the 36% unrealized capital gains tax, just passed by the House of Representatives, will work. Here is a more detailed example: Step 1. Starting position You own 500 shares. Value on Jan 1, 2028: €50,000 Value on Jan 1, 2029: €100,000 So the paper gain is: €100,000 − €50,000 = €50,000 unrealized profit You did not sell. But for tax purposes, that €50,000 is treated as income. Step 2. Apply exemption You are married, so you get a €3,600 exemption. €50,000 − €3,600 = €46,400 taxable amount Tax rate: 36% €46,400 × 36% = €16,704 tax bill That bill is due in May, even though you never sold anything. Step 3. Market falls before you pay Now suppose by May the shares drop in value. New total value: €60,000 So your portfolio is no longer worth €100,000. It’s worth €60,000. But the tax bill is still €16,704, because it was calculated based on the January 1 valuation. Step 4. You must sell shares to pay tax To raise €16,704, you sell part of your shares. After paying the tax, you’re left with: €60,000 − €16,704 = €43,296 Originally you had 500 shares. Now you have 360 shares left. You were forced to sell 140 shares. 140 ÷ 500 = 28% of your shares gone. Step 5. What happened economically? Before the correction: Paper gain was €50,000. After the correction: Portfolio is worth €60,000. Original cost basis was €50,000. Real gain is only €10,000. But you paid €16,704 in tax. So instead of being up €10,000, you are now: €43,296 − €50,000 = €6,704 below your original starting value. You turned a €10,000 real gain into a €6,704 net loss. And you lost 28% of your shares permanently.

Natural next step: Once this new form of entertainment takes hold, some people will be better at ”directing”. These will make for more interesting experiences. Then these people’s production can be put up for others to experience in a YouTube/GitHub-esque manner.

I bet a team of < 100 people can make this new form of personally catered entertainment, and it will have triple-A games quality and big budget movie quality at the same time.

This is actually my prediction for the future of entertainment: Moving images and games will merge into a choose your own adventure style form of entertainment where you both interact with the show as well as direct the story, all rendered in real time with the help of AI.

Someone should create a company that allows fans to continue the storylines from canceled TV series with AI producing the episodes. No need for spinning the actors back up. Let AI do it. Let fans create, share and consume. This would be huge.
