Erster Eindruck iPhone Duo: Vom Form Faktor eher ein Tablet mit Telefonfkt. Nur beidhändig bedienbar. Websites in Safari sehen schrecklich aus. TouchId-Button ist im Weg. Bin mehrmals versehentlich dran gekommen und damit das Duo gelockt. Screens mit Falz super; Sound sehr gut.

We all saw that disturbing footage yesterday of trump snarling at a reporter in the Oval Office.
But do you know what that reporter was trying to ask?
Trump just announced a new program that rewards people for reporting government fraud.
The reporter simply wanted to know why we need this new program when we’ve already had a law doing something similar since 1863, and that law actually pays whistleblowers a higher percentage.
THAT’S A DAMN GOOD QUESTION.
And here’s the crazy part. There was a perfectly reasonable answer! The new program is supposed to cover types of fraud the old law doesn’t.
THAT’S IT. THAT’S ALL HE HAD TO FUCKING SAY.
Instead, we watched the president and vice president turn a legitimate question into a confrontation.
This man is unhinged. The way he reacts to questions is disturbing. He treats every question like a personal attack. Every reporter is an enemy. Even the simplest fucking question becomes some kind of threat.
And that’s what worries me. We have a president who appears so defensive that he can’t even handle someone asking him to explain his own policies.
This is the President of the United States, folks.
And this shit is NOT normal.

Wow, the US truly has the most incompetent president in history.
Just listening to how clueless this man is, it’s no wonder we have been humiliated in Iran.
Trump: “The Russians had a thousand tanks riding up a concrete highway. They would have been in Ukraine in four hours, going maximum tank speed, which is 48 miles an hour, to be exact. Nothing to stop them. The war would have been over in one day. And this very stupid general - I have no idea who he is. I doubt he’s still with us. I doubt he’s still living. He decided to hang a right onto the farmland and then take a left and go up to Kyiv, rather than staying on the highway - the concrete highway, perfectly good highway - where they were doing very nicely. It would have been three and a half, four hours, and the whole war would have ended. He ended up getting stuck in the mud.”
Does he understand that Ukrainian troops destroyed all the bridges and cut off the retreat points, so the only option left was to go off the highway? I mean, if you have the IQ of a 10-year-old child, you should be able to get it.
I am honestly shocked at the basic level of ignorance. And this is the man who is in charge of the US Army.

I have read dozens of outraged posts because the US special envoy Witkoff called Putin a "humanist." But no one is writing about the fact that the American negotiators are simply not doing their job. Let me explain.
Peace negotiations are important in their own right. Even if they do not lead to a lasting peace, the process itself is an opportunity to resolve urgent humanitarian issues. If, of course, the human dimension is a priority for the negotiators. But it is entirely obvious that neither Witkoff nor Kushner cares about people's fates in this war.
The Pope calls on Putin to save thousands of people from starvation in occupied Oleshky and the surrounding villages. The UN speaks about a humanitarian catastrophe and asks Russia to allow the evacuation of the civilian population. European Parliament Vice-President Pina Picierno goes on a hunger strike to draw attention to this tragedy unfolding before the eyes of the whole world.
And what are Witkoff and Kushner doing?
That's right, almost nothing.
Except for passing along greetings from Putin’s aide to the First Lady.
Thousands of people are already eating grass to survive and begging to save their lives. The Ukrainian side raises the issue of Oleshky at every meeting. And I can name dozens of such urgent humanitarian issues off the top of my head where American negotiators must be proactive.
Trump’s peace negotiations have already gone down in history as the deadliest years for Ukraine’s civilian population since the start of the full-scale invasion.
I don’t know if anyone will remember the names of Witkoff and Kushner.
But history will certainly record how American negotiators, who had the opportunity to save a huge number of people, refused to raise uncomfortable questions before "humanist Putin."

I haven't been this excited about smartphone apps since 2008.
The iPhone Duo seems to have galvanized the developer community, leading to an explosion of novel concepts and new designs. Feels like the iPhone 3G all over again, and I'm *very much* here for it

Spent years watching models ace a single image and completely whiff on anything that moves or changes angle. Today we’re fixing that.

Meet Nigel. He’s not enjoying our cause-and-effect demo.
So I let him sit in the DeLorean. Still not happy.
I didn’t write his lines. What he says is generated from his personality and the context of the shot.
It’s an entirely new way to create: place imaginary characters in your world, record your performance, and let Simulon generate their reactions and realistically integrate them into your footage.

People seem confused about why Tesla is getting so much backlash over its new "flying Roadster." For those of us who were once genuinely enthusiastic about Tesla, this isn't about hating innovation. It's about a long history of broken promises, misleading expectations, and increasingly absurd marketing.
Tesla unveiled the second-generation Roadster in 2017, took customer deposits, and promised deliveries in 2020. Six years past that deadline, it still hasn't delivered the car. Instead, it's demonstrating an even more outrageous version with features that will likely never make it into production. The original 2nd gen Roadster would still be an amazing car today. Why not just deliver what was promised?
Then there's Full Self-Driving. Tesla marketed the idea that Model 3 owners could turn their cars into income-generating robotaxis. That never materialized. Even if the technology eventually gets there, the opportunity has already passed for many early buyers. Timing matters. Delivering something a decade late isn't fulfilling the promise you sold to customers.
And then there's Solar Roof. Unveiled in 2016 as a revolutionary approach to residential solar, it struggled with costs, installation challenges, and adoption far below expectations. After nearly a decade, Tesla discontinued it entirely in August 2026. Another grand vision abandoned, leaving existing customers with a discontinued product to maintain.
Then came the Cybertruck, marketed as a nearly indestructible, revolutionary truck. Instead, we got a vehicle with questionable build quality, numerous recalls, expensive repairs, disappointing results in several real-world off-road tests, and specifications that fell short of the original promises. It literally looks like a dumpster, but aesthetics aside, the collapsing demand speaks volumes about the reality of what Tesla delivered. Another heavily hyped product that fell dramatically short of expectations.
This is how consumer trust erodes. Not through one disappointment, but through years of accumulating them. And this is part of the reason why many people who were once enthusiastic about Tesla have become critical and cynical about it.
But there's something even more fundamental here: Tesla has completely departed from the grounded, practical vision that made so many of us enthusiastic about the company in the first place.
Electric cars were ambitious, but the idea was grounded in reality. People could charge at home, infrastructure could gradually expand, technology could improve, and millions of ordinary people could eventually benefit. There was a realistic path toward mass adoption.
What the hell does a flying Roadster powered by compressed-air thrusters have to do with any of that?
It's an expensive, impractical engineering stunt with enormous packaging, safety, and regulatory challenges, and no credible near-term path toward mass-market usefulness. Modern electric cars already achieve ridiculous acceleration without this nonsense. What practical problem does it solve? Who actually needs it? When will ordinary consumers benefit?
And watching Tesla fans compare this experimental prototype in a Roadster-shaped shell to actual production vehicles people can buy today is ridiculous.
What's especially infuriating is the cult-like mentality surrounding all of this. You can't point out the history of failed promises, question the practicality, or demand realistic timelines without being accused of being a "hater" or having "Elon derangement syndrome."
Tesla deserves recognition for helping make electric cars a reality, but that success doesn't give it a blank check to keep marketing increasingly fantastical promises while failing to deliver on previous commitments.
This isn't hatred. It's disappointment from people who once believed in the company, watched it accomplish extraordinary things, and have since watched it increasingly substitute practical innovation with spectacle and promises.
Elon fanboys are also ignoring a bigger pattern that goes beyond Tesla.
What made many of us enthusiastic about Elon and Tesla and in the first place was a grounded vision of technological progress that could genuinely improve millions of lives. Electric cars were ambitious, but practical, achievable, and useful to ordinary people. Now we're supposed to get excited about flying cars with compressed-air thrusters that have no credible path to mass adoption and solve no meaningful problem for the average consumer.
It's the same kind of thinking behind marketing the colonization of Mars as some urgent necessity for humanity's survival. There's nothing wrong with space exploration, but Earth isn't about to become uninhabitable because of the Sun. We're talking about geological timescales, while humanity faces enormous problems RIGHT NOW: poverty, hunger, access to education, corruption, abuse of power, wars, and a lack of government accountability. We have plenty of very real problems to solve before worrying about humanity's survival on another planet.
And then there's DOGE. I was genuinely excited about the original idea of making government more efficient, reducing waste, and increasing accountability. Instead, we got questionable savings figures, inexperienced people making sweeping decisions, serious concerns over access to sensitive personal information, and an initiative that ultimately fizzled out without delivering its grand promises. Another enormous narrative that fell apart when confronted with reality.
That's what makes all of this so frustrating. It's not that we stopped believing in technological progress. It's that we've watched someone who once pursued grounded, transformative ideas increasingly embrace fantastical promises, political spectacle, and questionable narratives disconnected from practical reality.
And somehow, pointing out this history of disappointment gets you labeled a "hater" or accused of having "Elon derangement syndrome."
The problem isn't dreaming big. It's repeatedly selling people those dreams, failing to deliver, and then expecting everyone to applaud the next, even more ridiculous promise without asking what happened to the last one.
The world doesn't need more spectacular promises. It needs practical solutions to real problems, honest expectations, and accountability for what was promised. That's what made Tesla exciting in the first place, and that's what so many of us feel has been betrayed.

🇨🇭🇩🇪 German manufacturing is undergoing a structural crisis, and credible identification of its causes clearly requires rigorous research. Yet my advice to fellow researchers remains the same, namely to study 🇨🇭 in depth, since, as the chart suggests, it offers an excellent counterfactual. Why is nobody studying the stellar performance of Swiss industry?
Very well written. Indeed, learning 3D Printing requires a lot of knowledge and trial and error. Therefore participants love our workshops / trainings in Switzerland for learning the whole process from ideation to getting repeatable high quality results. hancon.ch/schulungenworkshop…
3d printing becomes a lot more interesting once you stop thinking about what you can print and start thinking about what material the part actually needs. pla, petg, nylon and flexible resin might all produce something that looks similar, but mechanically they’re very different. pla is stiff, easy to print and excellent for prototypes. petg offers better toughness and layer adhesion, making it useful for functional parts. nylon brings wear resistance, toughness and good fatigue performance, which is why it appears in gears, hinges and moving mechanisms. flexible resin allows complex, compliant geometries, but its durability depends heavily on the formulation and curing process.
the interesting part is that material selection is only half the problem. print orientation, layer adhesion, wall thickness, infill, moisture, temperature and loading direction can completely change how a part behaves. a perfectly designed bracket can fail because the load pulls its layers apart. a nylon gear can perform poorly because the filament absorbed moisture before printing. a flexible part can lose its properties because the wrong resin or curing process was used. the same geometry, printed with different materials and parameters, can behave like an entirely different mechanical component.
this is why i think every engineer should learn additive manufacturing. you’re not just learning to operate a machine. you’re learning materials science, mechanical design, manufacturing constraints and failure analysis through direct experimentation. print a part, load it, break it, understand why it failed, change the design and repeat. the real value of owning a 3d printer isn’t producing plastic objects. it’s having a small manufacturing laboratory on your desk where you can turn engineering assumptions into physical evidence.
