Speciální díly neděláme s @kweenolog často. Tentokrát jsme ale udělali výjimku, protože Zineb Riboua je fenomén. Tři dny zpátky (pátek) jsem seděl v její kanceláři ve Washingtonu; a obrázek, který v pátek nakreslila se v sobotu stal. Proto jsme ji dnes v noci poprosili o 30min času. Díl níže i na platformách.

Do studia jsme opět pozvali top expertku na Blízký východ Dr. Zineb Riboua z Washingtonu. Řešili jsme posledních 48H v Íránu, ptali se, čeho chce Trump dosáhnout, proč je Írán neoddělitelný od Číny a co to znamená pro Rusko, země Perského zálivu, Izrael a Evropu. Celý díl níže.

A new study finds that work-from-home raises fertility more than any conventional family policy. "Estimated lifetime fertility is greater by 0.32 children per woman when both partners WFH one or more days per week as compared to the case where neither does." 🧵.

🇨🇿🫂🇺🇦 The collection of Czech citizens has just reached CZK 80,000,000 (and still growing) - The first generators purchased with these funds for Ukraine have already left Prague. 🥰 Thanks, Czechs!🫡

Moral Bankruptcy. While a horrific massacre takes place in Iran, the European Union clings to its old obsession. Instead of helping the people of Iran and promoting the designation of the Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization, the EU issues a statement on Israel that is, as usual, absurd. The European Union's assertions regarding Judea, Samaria, and Jerusalem do not align with the reality on the ground and ignore the historical, legal, and national right of the Jewish people to live in their homeland. Claims regarding a "risk to stability" consistently ignore the primary cause of instability in the region: Palestinian terrorism and incitement, and the persistent refusal to recognize Israel’s existence as the nation-state of the Jewish people.

We are Arabs. We are Muslims. We are Middle Eastern. And we banned the Muslim Brotherhood as terrorists. In Britain and Australia, they are allowed to operate and riot. Why are you trying to be more Muslim than Muslims themselves?

@samokhvalov Would be great to see TLS transfer method numbers. I guess it will perform better than SSH. But I admit that it will be more complex to set up.

#PostgresMarathon 2-012: Ultra-fast replica creation with pgBackRest postgres.ai/blog/20251105-… Couldn't believe the numbers: 35 TiB/h copying PGDATA from one EC2 instance to another. That's fast enough to clone a 10 TiB production database in ~17 minutes. Modern hardware + pgBackRest trick = game changer for zero-downtime operations at scale Credit: Maxim Boguk, Postgres expert I've known for years, who now helps the @postgres_ai team excel with really large systems [Chart showing throughput progression from 3.9 TiB/hour to 35+ TiB/hour when involving more processes]

I always say Israel is losing the PR war, but have a read at this...……. Mitch Schneider October 10 at 12:09 PM “I keep hearing that Israel "lost the PR war." And you know what? Fine. Sure. Whatever. The world thinks we're monsters. The UN passed over 30 resolutions condemning us. College campuses exploded with protests. "Genocide" trended on Twitter for 700 days straight. We lost the PR war. Congratulations to everyone who won it. Now let me tell you what we won instead. Two years ago, my country was surrounded. Hezbollah had 150,000 rockets aimed at us from the north. Hamas controlled Gaza with an army in tunnels beneath it. Iran was months from a nuclear weapon. The Houthis were firing missiles at our ships. Assad's Syria was an Iranian highway. Iraqi militias were itching for war. We called it the "ring of fire." Iran spent 40 years building it. Billions of dollars. Endless weapons. Thousands of fighters. All of it designed for one purpose: to destroy Israel in a coordinated attack. October 7th was supposed to be the beginning. Hamas attacks from the south, Hezbollah from the north, militias from the east, Houthis from the sea. The final war. You know what happened instead? Israel dismantled the entire thing. Piece by piece. Threat by threat. Not in some distant future. Not "eventually." In two years. Nasrallah spent 32 years building Hezbollah into the most powerful non-state military in the world. Israel killed him in his bunker and took out his entire command structure in weeks. Hezbollah isn't weakened. It's finished. Iran built a nuclear program for decades. Israel set it back years. Killed their top scientists. Destroyed their facilities. Made the regime so weak that its own people are revolting. Assad survived a civil war, Russian intervention, and American strikes. He couldn't survive losing his Iranian backers. His regime collapsed. The land bridge is gone. The Houthis thought they could close the Red Sea. Israel crippled their long-range capabilities and neutralized the threat. Hamas? Sinwar died in rubble clutching a stick. Haniyeh was eliminated in Tehran. Deif is gone. The tunnels are destroyed. And this week, Hamas agreed to a ceasefire and the release of all hostages. Read that again. The terrorist organization that started this war by massacring 1,200 people just agreed to release every hostage and accept a ceasefire on Israel's terms. So yeah. We lost the PR war. I'll take that loss. Because here's what we gained: My kids don't have to run to bomb shelters anymore. The north is being rebuilt. Hezbollah's rockets are gone. Iran's nuclear threat has been pushed back years. The tunnels under Gaza are rubble. The "ring of fire" is extinguished. And now? The hostages are coming home. There's a ceasefire. The fighting can finally end. Two years ago, we were facing an existential threat. Today, we're the dominant power in the Middle East. Here's the thing about the "PR war" - it's a luxury. It's what people with security worry about. It's optics. It's perception. It's whether someone with a blue checkmark likes you. Israel doesn't have that luxury. We never did. When people scream "genocide," we're preventing one. When they cry "disproportionate," we're stopping rockets. When they demand "ceasefire," we're rescuing hostages. While the world was busy judging us, we were busy surviving. And not just surviving. Winning. Fundamentally, decisively, historically winning. Iran's 40-year plan to surround and destroy Israel? Over. The axis of resistance? Shattered. The greatest coordinated threat in our history? Defeated. So let me ask you something: Would you rather win the PR war and lose your country? Or lose the PR war and secure your existence for the next 50 years? Because that's the actual choice. And Israel made it. Again. The world can have its hashtags. We'll take our sovereignty. They can have their protests. We'll take our security.

@artur_novy Jak dlouho Židům trvá uvědomit si, že volba fašistů byla chybná? To se zanedlouho dozvíme. Ti nízkopříjmoví voliči jdou proti sobě nejen ekonomicky, ale i bezpečnostně. Tak uvidíme, jak dlouho jim bude trvat, než jim to dojde.

Chcete o sobě a svých dětech nechat rozhodovat úplné dementy - volte SPD. Proruské bolševické kurvy, protože 40 let bídy a ponížení vám nestačilo - volte Stačilo! Pokud vám imponuje upištěnej pablb, pohrdající i dětmi a bojící se konverzace s oponenty z jiné pozice, než poroučení - voltě esťébáke, ostatní v ANO vůbec o ničem nerozhodují a mají jenom přemístit vaše peníze do Burešovi šrajtofle. A kdo si myslí, že infantilní Kikinův revival placenej vekslákama brzdí green deal, je slušně řečeno intelektuálně nesmělej

Moldavsko je jedna z nejchudších zemí Evropy, která byla dlouhá desetiletí periferní částí sovětské říše. Tamní volby měly být pro Kreml rozcvičkou před důležitými volbami v ČR, měl za to, že je zvládne. Projel to na celé čáře. Co ty, bohaté Česko, tolik hrdé na svou vyspělost?😉

Nacionalisté, komunisté a Zeman vyhrožují zvolenému prezidentovi ČR. Jsou si jisti, že když je demokraté nechají vyhrát volby, Moskva je proti Pavlovi podpoří. Jen potřebují, aby lidé nepřišli volit proti této chásce.
