Joining clean & transparent plastics w/o adhesives or solvents. We at Kurz and our peers at @LPKF developed a new transparent particel-free laser welding technology ready to be used in micro fludics, medical devices and point-of-care diagnostics. Seamless integration. Traceless welds. Full transparency. @LPKF_USA

@Chris_OH58D Let me introduce you to the type-j triplet.

Maybe just introduce proper sockets.

@nic_amadio Expats verändern das Wohnen in der Schweiz – die einstige Zürcher Pfnüselküste heisst heute Platinküste nzz.ch/nzz-am-sonntag…

Let me introduce you to: the platinum shore. Gentrification powered by the free movement of ppl and a series of almost four decades in bilateral agreements. Yes, this has been great for me and my family. However, I do see so many local young families struggle. What a brutal and honest world we live in. The strict housing and building regulations sure are the main catalyst for the skyrocketing home prices. These regulations are in stark contrast to the often so free market oriented Swiss economy. Many of the displaced families depend on a local salary. Many of the displacing come in with a global (capital) income. There just was a great article on the matter in NZZ — link below.

My take on these 2 setups (there's also a 3rd, good setup not discussed here, which I'll post about next week): 1. Zug LLC setup Lucerne area for life-base is good/great. Another good alternative not mentioned by Ale is Horgen in Zurich. By train: • 10m to Zug • 25m to Zurich HB • 40m to airport (direct) Hard to beat. Lucerne is like 1h+ for almost anything except for zug (20-30m). If you're keeping most of your profit in the LLC and reinvesting it there, then the income tax difference on the income you'll take out for living expenses won't make a big difference with lucerne (not tax advice). Also health insurance not a big difference. Plus: Horgen is by the lake, with decent beaches. Thalwil is a decent/good alternative to Horgen as well. A good thing about Horgen/Thalwil is that you get most Uber Eats restaurants to deliver there. Delivery costs will be ~10 CHF but if you do Uber Eats One sub (~20 CHF/mo) then it's free. 2. Lugano You pay the highest health insurance in CH for the worst healthcare facilities in CH (more or less). 'Cause it's a small town. But: also not too bad cause anyway healthcare in CH is centralised, so if you need to, you'll be rerouted to better facilities in other cantons. Also some of the worse infra in CH (but still good for global standards). But you need a car, unlike 90% of CH. Another good option if you value proximity to Milan is Mendrisio: 1h to Milan by car door to door, instead of 1h30m of Lugano. Ticino in general you get more sun, proximity to Milan (but also Liguria for beaches, and Piedmont for food/wine/nature), and are still close to ski slopes. Lake water is worse than in German CH, but still OK for global standards (less clean, although a tad bit warmer). --- I will write (probably next week) about another 3rd option which I think might interesting for Swissmaxxing. And I'll attach in the comments a guide on Swiss cities (for paid subs of Remote GOATs dot com) and some free articles on Lugano, Zurich, and CH setups.

@IncognitoIceMan @i2cjak You might be interested but in this emerging new technology they call an electro magnet. On a good day the LHC is pumping 1.5 MA* through its veins. * mega Amps, that’s a one with six zeros before the A.

@EngelJona @i2cjak Nope, that goes the other direction

finding that I desperately need a 0.1V 1000A power supply

Going to see a lot more local for local. It’s a yes for global businesses. It’s a yes for supply chain resilience. It’s a yes for security. For many, it will make an enormous bag of deferred investments visible. Not at last in workforce education.

@DJSnM @AudreyPorne So does the Swiss j-type, in a much more compact and tidy way.

@AudreyPorne American’s complain that the plugs in Britain are so big, but they handle twice the voltage and power, and also include fuses in the plug.

Americans not having electric kettles is kind of insane, no?

The BEV critics are not ready for the full rollout of those current gen EVs with >700 km range.

@FabianoSolana CHF is just living in a different world.

Gold is crashing. Silver is crashing. Crypto is crashing. Stocks are crashing. The dollar is crashing. There's only one thing not crashing...

@roeymiterany @theapplecycle @privatetalky So much untouched potential on FP64 flops. Greetings from the HPC & multi physics world.

I’m not sure what meaningful upgrades are left for the M series. I’ve been using the M4 Air, and it already feels like a real powerhouse. I don’t see a reason to upgrade for the next 3–4 years. If anything, improvements could focus on: 1. GPU performance 2. AI-related capabilities 3. Battery life Beyond that, it’s mostly incremental.

The all-new MacBook Pro is now 7 months away! 👀

@predict_addict @grok @grok analysis the federal budget for the ETH domain and discuss if it is an investment in the sense defined above.

@EngelJona @grok It’s not “investment” it is cost. Investment is something that results in creating long lasting assets. Most of this spend results in subpar skills and large number of migrants

I didn’t realise that some supposedly “elite” universities in Europe often skip proper oral/verbal exams in core subjects and instead use multiple choice formats. This feels off for university-level assessment. This isn’t a school test or even an entry exam — it’s an actual exam from a top 10 European technical university. At least ETH is transparent about it publicly. TU Munich doesn’t even publish exams - wonder why. It may help explain some of the outcomes we’ve been discussing. Low structured teaching hours, limited upfront selection, and these assessment methods raise questions about the overall model.

@predict_addict @grok Swiss Federal spending on the ETH budget is among the highest total return investment a tax’s can pay.

@EngelJona Needles to say Swiss taxpayers are paying for it and many use ETH and other universities as immigration vehicles @grok what is percentage of non Swiss students in ETH programs by faculty?

It’s basically the real entry exam. As it’s a public education, everyone who finishes high school is allowed to give it a shot. For most, this sort of university education or the specific topic might not be the right fit. So students have one year to find out, learn and show. It’s not the Anglo-Saxon approach.

@EngelJona No it is a function of turning universities into conveyors. How can supposedly “elite” university have 700 students at one course? This is totally insane

@homegymcoop You should really consider Osmium.

I want to start a gym equipment company that makes everything out of tungsten instead of steel or cast iron. This way you could truly justify every home gym purchase as an “investment.”

@dwarkesh_sp @DanielleFong Na. We are golden here. We will run out of copper fast enough that the tire 2 suppliers of ASML should make sure to not overspent on the hype. Energy and energy distribution, let alone the whole capex and return on capital tropic, will be the bottlenecks.

EUV machines are the most complicated tools humans make. Their supply chain has over 10,000 individual suppliers, and any one of them not scaling fast enough can bottleneck the entire AI industry. An EUV tool fires lasers at a tiny tin droplet three times in precise sequence, blasting it hard enough to emit EUV light. That light bounces off 18 multilayer mirrors onto the wafer. Meanwhile, the two platforms inside the machine - one holding the stencil, one holding the chip - are flying back and forth at 9Gs in opposite directions. The successive passes have to land on top of each other to within 3 nanometers. If any part of this is off, yield goes to zero. Take just one component. The mirrors are mostly supplied by Carl Zeiss, who have probably fewer than a thousand people working on them. In turn, Carl Zeiss rely on machines from Switzerland to deposit each of the layers, and use a coating process co-developed with a different German company. None of these companies have woken up. They’re gradually increasing production, but nowhere near the levels necessary for what the labs want by the end of the decade. @dylan522p predicts production can't scale beyond about 100 EUV machines per year by 2030, no matter how much money gets thrown at the problem. In the medium term this is the key bottleneck on scaling.

@ProfessorPape This might be neglecting a big piece behind much of global trade. Reuters’ Clair Farley et al give another perspective reuters.com/graphics/IRAN-…

Iran hit 16 vessels so far in Strait of Hormuz. That’s all it takes for Iran to control 20% of the world’s oil and become an oil hegemon — the number 1 strategic outcome US has sought to prevent in Middle East since 1970s. Iran is not weakening— it is gaining power.
