Since GPT-6 Astra launched on September 3, PCB fabs, AI tool makers, and independent engineers have run PCB design tests with it. We follow this topic closely, so we read and summarized all available reports. The boards are two to six layers, Freerouting often did the routing, and none of the reports says how much cleanup it took to get to a board you would send to fab. We also looked at the gigabit switch an engineer at @OpenAI posted this weekend. quilter.ai/blog/gpt-6-astra-…

As an architect, I believe these collapses are symptoms, not accidents: the outcome of a built-environment ecosystem whose structural flaws run far deeper than any single site. 🧵 I have attempted to ventilate on the issues I feel need to be addressed urgently along with possible solutions for evaluation. 1. Our zoning regulations are clear on paper, yet divorced from the ground. Relentless land fragmentation yields plots too small to honour setbacks, building lines and coverage limits. (On a 50x100, compliance may leave a quarter of a premium plot buildable.) Meanwhile, the street has already drawn its own building line, beacon to beacon. Out of this dissonance, the industry has normalised two parallel realities: a compliant set of drawings for approval, another for the site. Or no approval at all; build now and regularize later. Neither option survives without the inspectorate's knowledge. Their vigilance is formidable. (Try replacing the tiles in your own bathroom and see how swiftly they appear.) To cast the architect as the culprit is to credit us with a power over sites we simply do not hold. 2. I dare propose that just as licensed doctors treat without seeking permission per patient, let registered architects, engineers and contractors self-certify, bearing full legal liability for code compliance, while counties register projects for record and revenue as does the NCA. This will help to cure protracted delays which erode financial models and tempt developers toward self-help. I do not think counties can afford the technical depth to interrogate submissions sufficiently. In any case, they disclaim responsibility for the very designs they approve through signing of mandatory indemnity forms. 3. Design professionals remain the most undervalued link in the supply chain, undercut by unregulated practitioners and developers who view fees as negotiable. When expertise is paid in peanuts, diligence is the first thing to erode. Building collapses are the sum of a system in which planning, approval and remuneration all reward the shortcut. Until we redesign that system, we will keep mourning lives. #BuildingCollapse #Nairobi #ArchitectureKE

Why Does √3 Appear in 3-Phase Formulas? In a balanced 3-phase system, the phases are separated by 120°. This geometry creates the √3 factor when converting between phase and line voltages or currents. Line Voltage = √3 × Phase Voltage Example: 230V × √3 ≈ 400V.

We had a Linux server that showed two successful SSH logins from an external IP overnight. The strange part was that there were no failed password attempts before them. The attacker got in cleanly. So I checked the SSH logs properly. Both sessions said: Accepted publickey That meant we were not dealing with a guessed password. I pulled the fingerprint from the logs and compared it with the keys in: /home/deploy/.ssh/authorized_keys There was only one key there. And it matched. The comment on the key was: deploy@old-build That name sounded familiar, so we checked our records. The build server it belonged to had been retired months ago. But nobody had removed its SSH key from this production server. I checked the timestamp on authorized_keys. The key had been sitting there since November 2025. So this was not some new persistence the attacker had just created. It was an old trust relationship we had forgotten about. That was actually worse in a different way. I checked the login history and confirmed both sessions came from the same external IP. Then I looked for files touched during those sessions. A backup copy of the application’s .env file had been created under /opt/api/. That immediately raised another concern because environment files often contain things like database credentials, API keys and application secrets. At that point we disabled the deployment account, removed the stale key, rotated the application secrets and started checking every other server that might still trust the same old build key. The lesson from this one was simple. Not every compromise starts with malware. Sometimes the attacker just finds a credential or key that your own environment forgot existed. Passwords expire. Employees leave. Servers get retired. But SSH keys can quietly sit in authorized_keys for years if nobody is actually reviewing them. That is why key rotation and access reviews matter. The attacker did not need to break SSH. We had already left the door open.

Government websites across Denmark, France, the Netherlands and Finland were taken offline after the disclosure of a widespread security vulnerability. PHP has issued an urgent security update and warned that hackers worldwide could exploit the flaw within a short time.
The NSA has warned over two critical PHP security flaws that could put websites worldwide at risk, telling organizations to take affected systems offline if they cannot be secured immediately. Belgium's foreign ministry temporarily pulled its websites following reports of cyberattacks exploiting the PHP vulnerability. The Centre for Cybersecurity Belgium has recorded no attacks on Belgian websites. Japan PM Takaichi urged checking whether sites use PHP and applying the fix patch. CISA: no observed exploitation, but the flaws pose a risk to unpatched organizations.

1/3 Sifuna Too Young to Lead? In 1963 He Would Have Been Too Old. @edwinsifuna Edwin Sifuna is 44. In 2026, that apparently makes him too young to lead Kenya. In 1963, it would have made him one of the older men in the room. That is the uncomfortable truth our political elders would rather we forget. The Kenya that won independence was not built by grey-haired patriarchs waiting patiently for their turn. It was built by young men and women in their twenties and thirties who were handed the keys to a nation and told to make it work. Today, the beneficiaries of that faith in youth are telling a 44-year-old senator to sit down and wait. Either we are very poor in history, or we suffer from a serious case of selective amnesia. The latest round began when COTU Secretary General Francis Atwoli suggested Sifuna is too young to run for the presidency and should wait his turn. The Constitution sets the minimum age for a presidential candidate at 35. Sifuna clears that bar by nine years. So the objection is not legal. It is cultural, and measured against our own past, it is nonsense. The boy wonder who built a nation Start with Tom Mboya. He was in his early twenties when he took charge of the Kenya Federation of Labour. He was elected to the Legislative Council at 27. At 28 he chaired the All-African Peoples' Conference in Accra and stood before the leaders of an entire continent. That same year, still only 28, he stood beside Martin Luther King Jr. before 20,000 people at the Washington Monument, demanding an end to segregated schools in America. Weeks later, King personally went to Atlanta airport to welcome his plane, then hosted a dinner in his honour and introduced him as a symbol of the world's hunger for freedom and human dignity. Let that sink in. The most celebrated moral voice of the twentieth century treated a 28-year-old Kenyan as a peer. In March 1960, at 29, he was on the cover of TIME magazine, the first Kenyan ever to appear there. At around 30 he was the founding Secretary General of KANU and a leading negotiator at Lancaster House, sitting across the table from the British Empire and bargaining for our independence. He was a Cabinet Minister in his early thirties and wrote the blueprint of Sessional Paper No. 10 of 1965 at 35. He was assassinated at 38. Everything we honour Tom Mboya for, he achieved before reaching Sifuna's current age. The greatest proof of what a young man can do is the Airlift.In 1959, a 29-year-old Mboya looked at a colony on the eve of freedom and saw a nation with almost no university graduates to run it. He did not wait for permission. He did not wait for the colonial government, which was openly hostile to the idea. He flew to America, knocked on doors, raised money from ordinary Americans, persuaded colleges to open their gates, and won the backing of Jackie Robinson, Harry Belafonte, Martin Luther King Jr. and a young senator named John F. Kennedy. Between 1959 and 1963, hundreds of young Kenyans and East Africans crossed the Atlantic to study at American universities. Look at who came out of that dream. Wangari Maathai, who went on to become the first African woman to win the Nobel Peace Prize. Barack Obama Sr., a young economist from Siaya whose American education belongs to that same wave of Mboya's scholarship drive, and whose son would one day sit in the White House. Doctors, engineers, economists, diplomats and professors who would staff ministries, hospitals and universities across a newly independent Kenya. Pause on that. A man under 30 conceived, funded and executed one of the most consequential human capital projects in African history. He shaped the future of a nation, and arguably the politics of the most powerful country on earth, before his 30th birthday. Today we tell a 44-year-old senator he lacks the maturity to lead.

I am a member of the Norwegian Nobel Committee. There are five of us. Five people, appointed by a parliament most of the planet could not find on a map, who decide, once a year, which human being the world has agreed to call good. I know. I know. I think about it on the tram. We meet in a building on Henrik Ibsens gate, a street named after a man who wrote almost exclusively about people discovering they are frauds, which nobody on the committee finds funny except me. There is a room with a long table and the portraits of the dead laureates looking down, Mandela, the Dalai Lama, a great many earnest men in spectacles, and one portrait we do not discuss, which is Kissinger, 1973, awarded while the bombs were still falling, after which two of our predecessors resigned and the satirist Tom Lehrer said political satire was now obsolete. We keep him on the wall. A reminder. Every family has the uncle. It is October in Oslo, which means the sun gives up around four in the afternoon like a civil servant, and it rains the particular Norwegian rain that isn’t quite falling, just hanging there, judging you. I arrive with wet shoes. I always arrive with wet shoes. There is coffee, because this is Norway and there is always coffee, we drink more of it per person than almost anyone alive, and someone’s wife has sent kanelboller, the cinnamon buns, and we sit, five Norwegians, damp, caffeinated, sugared, and we decide the moral standing of the entire species. Let me tell you how it actually works, because the world imagines a cathedral and it is, I promise you, a book club with a mandate. 287 nominations this year. 208 people, 79 organizations. Anyone can nominate, that’s the secret nobody understands: a professor, a parliamentarian, a former laureate, so the “nominee” list is meaningless, it’s a suggestion box, and every autumn some congressman nominates his own golden retriever and the press writes “SHORTLISTED.” Nobody is shortlisted. There is no short list the public ever sees. There is us, and the coffee, and the rain, and the portraits, and a Norwegian stubbornness that is older than the prize itself. We read reports. The institute’s advisers write them, thick dull documents, and we argue. Our chairman told the BBC once that in the final meeting “there is a high temperature.” High temperature, for a Norwegian, means someone slightly raised an eyebrow and then apologized for it. We don’t do high temperature. We do a long silence, and then Kristin says “well,” and everyone knows exactly what “well” meant, and it’s settled. That’s our shouting. “Well.” You’d have to be raised here to hear the violence in it. Now. This year. I will not say the name, because we never say the name, but you know the name. A certain head of state wanted this prize the way a child wants a thing in a shop window, which is to say loudly, and in public, and with the full belief that wanting it was itself the argument. He said he deserved it. He said he’d ended eight wars, a number that grew most times he said it, like a fish. He had other heads of state phone us. Israel’s prime minister posted it on the internet, “Give him the Nobel.” The leaders of Cambodia and Pakistan announced they’d nominated him, as though announcing it were part of it, as though we tally mentions. A man flew around the globe collecting endorsements for a Norwegian committee the way you’d collect signatures for a petition to the council about a noisy dog. And here, uff da, is the detail I treasure, the one that makes me smile into my coffee. The nomination deadline is the 31st of January. He took office on the 20th. So for all the phone calls, all the posts, all the gilded lobbying, the only nominations that could possibly count for this year’s prize were filed in the first eleven days of his term, before he had, by his own arithmetic, ended a single one of the eight wars. He campaigned all year for a prize whose window had shut while he was still hanging up his coat. We didn’t have to reject him. The calendar did. We just watched. Norwegians are very good at watching. We have long winters. People think we sit there weighing his deeds. We don’t. That’s the thing I can’t make the world understand. We’re not grading his homework. We don’t owe anyone the prize for a ceasefire, however real, however loud the announcement. “He made peace” is not a sentence that ends in a medal, the way he believes it does, the way he believes every good thing ends in his name on it. The will of a dead Swede says the prize goes to whoever did the most for fraternity between nations. A dead Swede, I should add, who made his entire fortune inventing dynamite and selling arms, and spent his last years horrified at his own obituary, which called him a merchant of death, and so bought his way to immortality as a man of peace. The whole prize is one guilty arms dealer’s attempt to launder his name. We are, all of us, administering a dead man’s public relations. I find this clarifying. It keeps me humble. It should keep everyone humble, and it keeps, by my count, no one humble at all. So who did we give it to? An eighty-five-year-old woman. A judge. Born in Durban, under apartheid, granddaughter of a Tamil man who came to South Africa as indentured labor, a bus driver’s daughter from the poor Indian quarter, who became the first non-white woman to run a law practice in her province, who defended Mandela’s people when defending them was dangerous, who sat on the Rwanda tribunal and the court at the Hague, and who, at eighty-five, is right now a judge weighing whether a genocide is a genocide. When we told the world, our chairman said the rule of law “underpins the system we have set up to ensure peace,” and that “peace requires justice.” She wasn’t even in Oslo. She was in Nuremberg. In courtroom 600. The actual room where they tried the Nazis. You cannot stage that. God staged that, and God, it turns out, is a better satirist than any of us. She did not phone us. She did not post. No prime minister demanded it for her on the internet. She had, as far as our deliberations are concerned, the one qualification the loud man could never manufacture, which is that she wanted the work and not the medal. The medal finds those people. It flees the ones who chase it. This is not a rule we wrote. It’s just the only pattern the hundred-odd years of our mistakes has ever shown. The reaction from across the ocean was immediate. His spokesman posted that we “place politics over peace.” Ja. Perhaps. We’re five damp pensioners in a rainy city; of course it’s political, it was always political, it was political when we gave it to a sitting American president nine months into his first term for the promise of things he had not yet done, and we have been quietly embarrassed about that one for fifteen years, so believe me, we had a particular reason this year to prefer a woman with fifty years of verdicts behind her over a man with eight wars in front of him and a deadline already behind him. Here is what he will never understand, the thing I’d tell him on the tram if he ever took one. We are the one prize he cannot buy, cannot post his way to, cannot have a friendly dictator phone in for him. Not because we’re incorruptible, nei, we’re as vain and wrong and human as the portraits on our wall. But because the entire point of the thing, the only power a small cold country’s book club has ever held, is that it goes to the person not performing the wanting. The moment you demand it, you’ve proven you don’t understand what it’s for, and proving that is itself the disqualification. He ran the most expensive campaign in the history of the prize and the campaign was the reason. He was never losing to Navi Pillay. He was losing to the concept. It’s dark now. Four o’clock dark. The buns are gone. Kristin said “well” an hour ago and we all went home. I’m on the tram with my wet shoes, and somewhere across the water a very powerful man is explaining to a camera that the prize is rigged, that we’re corrupt, that he’ll win it next year, and he genuinely might, we’re only five idiots and we’ve been wrong before, Kissinger is still on the wall. But not this year. This year an old woman in Nuremberg, in the room where the law once stared down the exact kind of man who thinks wanting a thing loudly enough should make it his, got a phone call she didn’t ask for. That’s the job. We don’t reward the man who ends the war and announces it. We reward the woman who spent fifty years deciding what a war was. He’ll never see the difference. That’s rather the whole point of him. Takk for i dag. I have to change trams.

Scientists just built a clock that loses 1 second every 30 million years. Not an atomic clock. A nuclear clock. It uses thorium-229 nuclei instead of electrons. Nuclei are 10,000× smaller than atoms. Less affected by magnetic fields, heat, vibration. The clock locks onto a laser frequency, corrects its own drift in real time, and ran for 24 hours without intervention. Relative precision: 10⁻¹⁵. GPS currently uses atomic clocks at ~10⁻¹³. Nuclear clocks could be 100× more precise, and small enough to carry in a spacecraft. TU Wien + PTB Braunschweig. Published Nature, Oct 10 2026.
