Europe is in hibernation mode and it's both scary and embarrassing. And unfortunately, it's not clear if it will be able to evolve to save itself in time.
Oleksandr Yakovenko@alex_chenkov

Dear Mr. Armin Papperger, CEO of Rheinmetall, When you referred to Ukrainian drone manufacturers as “Ukrainian housewives with 3D printers” you revealed just how deeply the European defense establishment still fails to understand the nature of modern warfare. This is not about emotion. It is about battlefield reality. Here are the facts your industry refuses to acknowledge: In 2025 alone, Ukrainian drones carried out 819,737 confirmed strikes. They caused 90 percent of all Russian combat losses, more than all other weapons systems combined. TAF alone produces up to 100к FPV drones monthly. In any given 90-day period, my company’s products alone achieve more confirmed strikes than your entire fleet of equipment has across its full combat history in every conflict. And most importantly, I built this company and achieved these results in two years, not fifty. Think about that. Our drones generate more kinetic effect in three months than your flagship platforms have in half a century. Why? Because the battlefield has changed, and your business model has not. •Russian electronic warfare has made GPS-guided Western munitions such as Excalibur and GMLRS nearly ineffective. •Expensive and complex systems designed for wars with air superiority and traditional peer-to-peer combat have become easy prey for drones costing $500, attacking them from above. •The cost-to-effect ratio has been turned upside down: one 120 mm Rheinmetall shell or one anti-tank missile costs more than a dozen of our drones, and yet our drones still win. This is not a “Lego game.” It is industrial Darwinism in real time. We iterate every week. We print parts in basements and ship 100к strike systems per month, while your engineers still require three to five years and hundreds of millions of euros in certification costs for even a minor upgrade. The war in Ukraine is not a temporary anomaly. It is the first true drone-industrial war. And it has already proven that outdated European platforms, no matter how expensive or “serious” they may seem, are becoming less and less relevant unless they integrate the very technologies you mock. So when you say, “this is not innovation,” I hear something else: “We do not want to admit that the future is being written in Ukrainian workshops, not in Düsseldorf boardrooms.” #MadeByHousewives is trending for a reason. Because these “housewives” destroy more enemy equipment every month than entire European armies do in full campaigns. And they do it while your industry continues to sell 20th-century solutions at 21st prices. The invitation remains open, Mr. Papperger. Stop laughing at the kitchen table. Come and learn how tomorrow’s war is actually being fought. Because the next time someone asks, “Who needs tanks in the age of drones?”, the answer may be simpler than you think: Whoever still believes in 1979 will lose to whoever is building in 2026. With respect, but with facts, Oleksandr Yakovenko “Ukrainian housewives” Founder TAF

@dragonflydb @CeleryOrg @laravelphp Not everything compresses equally. RQ, Dramatiq, Taskiq — minimal gains. Different data structures, less redundancy. This is pattern-dependent. But for JSON-heavy list workloads, the savings are dramatic.

The interesting question: can the data store itself do something about it? Most of these payloads are highly structured and repetitive — class names, queue metadata, retry configs. All screaming for compression. We're working on something at @dragonflydb. Early results are very promising. Stay tuned.

I got curious: how much memory do popular job queues actually use in Redis? I benchmarked @celeryorg, @laravelphp, Sidekiq, RQ, Dramatiq, and others — 200K jobs across 10 queues each. The differences are massive. 📷

@elonmusk @elonmusk it creates nudity even if not asked. Including full frontal nudity or drawing naked little girls based on the innocent prompt asking to draw princesses. Better fix it quick.

@elonmusk @aibiceps I wanted to draw princesses for my daughter. Typed the prompt based on her request and imagine created bunch of naked girls at all ages - including naked little girls. Did not find any control within the product to mark it as porn. @elonmusk - I suggest fixing it.

Today, I am proud to be Israeli. Despite all the shaming. Despite all the UN "resolutions". Despite all the academics. Despite all the online pressure. Israel is cleaning the Middle East from radical religious terrorists. One by one. They will not thank us for it. But someone had to do the job.

The worst thing is that it happened for no reason. The pacifist Hamas society, composed entirely of doctors under the age of 18, was "unprovokedly genocided" - actual language - from the sky like the planet Alderaan. Horrific. Gaza, both a concentration camp and a lively rave that was easy to leave, is now gone. For no reason. Never forget EIGHT October, 2023.

@Yuchenj_UW @_arohan_ Agree that as a junior engineer you become much more productive and capable. But how do you actually learn as a human without having a "learning curve"? AI brings speed and abilities but takes away the sweat.

ex-Google and Meta distinguished engineer, Gemini co-author @_arohan_: “if I had agentic coding and particularly opus, I would have saved myself first 6 years of my work compressed into few months.” This matches my experience. AI collapses the learning curve, and turns junior engineers into senior engineers dramatically fast. New-hire onboarding on large codebases shrinks from months to days. What used to take hours of Googling and Stack Overflow is now a single prompt. AI is also a good mentor and pair programmer. Agency is all you need now.

Claude Code built in an hour what took a Google team a year. That part isn’t shocking. What is shocking is that Google allows their engineers to use Claude Code instead of forcing Gemini, Gemini CLI, or Antigravity. Giving engineers access to the best AI coding tool is the best decision you can make.

@lemire Soviet Union fell due to another "bug": the most "powerful" person at that time decided to make a change. Of course the environment at that time was already disfunctional, but they could carry on without the regime change if they wanted. People did not actively protest.

We have decades—or more—of studies on what makes totalitarianism work. Some of the world’s best intellectuals were trapped in the Soviet Union. We have seen multiple instances of the rise and fall of totalitarian regimes. Germany fell into it in 1933 and, arguably, much of the country only escaped totalitarianism around 1989. All of Chinese society descended into madness for years during the Cultural Revolution. The naïve view is that it is a top-down phenomenon driven by a few powerful individuals. Iran fell to Islamism because of one particularly charismatic and cruel leader; the same for Germany, and so on. But that is not the case at all. Totalitarianism is essentially a software bug—a mathematical phenomenon. It is the ultimate game-theory challenge. Totalitarian thought acquires a life of its own. It resembles how all teenagers suddenly start wearing the same type of jeans at the same time, but at a much greater scale. You imagine that, if you lived in Iran, you would have openly fought the regime every day for the past ten years. You imagine that, in 1938 Berlin, you would have stood up for the Jews. But you most likely would not have. And what if you had been a powerful person—say, the mayor of Tehran? Then you could have easily done something? No. That is the whole point: the entire society is captured, which is why it is totalitarian. It is not eternal and can collapse, but not easily and not predictably. The key lesson is that you are likely no better in this regard than the Iranians. How do you fight? It seems that the most effective counter-totalitarian technique is an minimally coordinated collection of small networks. That is, you make the system fragile from the ground up a bit like multiple infections and parasites can take down a beast. It is easy for the Iranian government to control a TV network. It is significantly more difficult to break multiple informal systems. grokipedia.com/page/parallel_…

\\ As Iranians rise up, a reminder that totalitarianism Isn’t Just “Extreme Authoritarianism” — It’s a Social Mathematics Problem // When talking about Iran and these waves of protest, it’s important to remind people what totalitarianism actually is — and why overthrowing it is mathematically difficult, even when most of the population opposes the regime. Totalitarianism isn’t simply “top-down authoritarianism done really, really efficiently.” It’s a psychological state a society enters — a social mania or cult built on righteous narratives, purity tests, and new definitions of who is unclean and must be hated. Crucially, it is enforced from the bottom up. Ordinary citizens — neighbors, coworkers, even family — become the monitors and enforcers, and they demand the top-down repression that inevitably follows. We saw a softer variant of this dynamic during Covid. And it doesn’t require a majority. A sufficiently zealous minority can dominate public life while the rest of the population keeps its head down — intimidated, disorganized, and terrified of displaying anything less than full enthusiasm. Everyone knows they’re being watched. So yes, in places like Iran it is entirely possible — and even common — for the vast majority to oppose the system that governs them. That’s when outsiders ask the perennial question: “If most people oppose the regime, why don’t they just overrun it?” Even ignoring the regime’s capacity for violence, the answer lies in coordination mathematics. The first person to raise their head, to openly resist or try to rally others, is the one most likely to be arrested, tortured, killed — and to see their family destroyed. No one wants to be that person. Each individual will only step forward if they’re confident that many others will step forward at the same time. But everyone is thinking the same thing. This is a society-scale variation of the Prisoner’s Dilemma: the individually rational strategy is to remain silent, even though the collectively rational strategy would be to rise up together. And so the stalemate persists — sometimes for generations. What makes the present moment in Iran significant is that people have again pushed past that initial barrier — at least for now. Enough of them are taking simultaneous risks to make protest possible. The next inflection point lies within the military and security services. There, the very same coordination dilemma repeats — only now among officers and commanders. Who defects first? Who risks everything, without knowing whether others will follow? That is the brutal arithmetic of totalitarianism. Overthrowing it is never just a question of courage — it is a question of coordination under fear.

Exact numbers on IDF strikes in Gaza are disputed. UN reports (as of 2024) indicate direct hits on 212+ schools and 94+ health attacks early on; HRW notes widespread residential destruction, with 1.9M displaced by 2025. Israeli sources claim targeted ops against Hamas sites. Maria Avdeeva's posts focus on Ukraine; no public condemnations of IDF actions found in her X history.

Horrendous. Russia massively attacks Kyiv. Multiple residential buildings hit. One third of the city is without heating. Bastards.
