There is market opportunity, China has found it, but the US won't allow them to be imported because it undercuts everyone else so thoroughly. The US automotive market is extremely far from being a free and open market. You can't just build a car to a set of standards and automatically be allowed to sell them, there are substantial legal and political barriers that cost tons of money to overcome, which doesn't make financial sense to anyone with that amount of money to just sell low margin vehicles.

Photogrammetry is one. Generally results in messy geometry though and tolerances get finicky.

The CAD plugin in Blender is my favorite though. Need a caliper to get measurements and then I can build out my hooks/clamps/whatever. FreeCAD for when I just need sketches as I find the solid part workflow utterly confusing, whereas I'm very well versed in Blender.

The premise of "fuck it" as put forth by the author, when the victim ends up paying that erroneous bill due to the thousands of litres of "sludge" poured out by the offending organisation can no doubt be identified as the root cause of rep's general attitude towards their customers and direct managerial hierarchy.

Awful wages, toxic work environments, long, thankless hours and disparaging company culture - all arguably by design - is contributing to this sludge that everyone reading this comment often encounters.

The common approach is to take a photo of an object from above together with a ruler or something of a known size for scale, then import that directly into the CAD software, scale according to the scaling object, and create a cutout along the object's outline. No need for calipers, 3d scans, or other complex measurement procedures. There are a lot of videos and guides on how to do that.

> You'd lose things like hardware acceleration.

I've been gaming through a VM for the last few years now, and hw acceleration is not an issue.

You would passthrough a GPU and then enjoy near native performance.

I use iGPU for my Linux desktop and a dGPU passed through to my gaming vm.

I also passthrough the whole bluetooth device to the VM as I don't use bluetooth on my host anyway. That way I can use gamepads and headset in the vm, too.

Inflation is a result of too much money being created than what is needed by the growth of the economy. Average price increase that we use to estimate it is just a useful proxy.

Inflation is always the main contribution to price increase. It only makes sense to compare price raise above or below inflation if you want to unearth factors specific to any given product or industry.

For me the best insight learned from wearing a GCM is that a cardio exercise with 150bpm heart rate for 40min+ is probably not healthy. I would easily see my glucose level drop to below 80 mg/dL (5 mmol/L) 30min into the exercise. I always thought the exhaustion towards the end of my exercise was due to normal fatigue, and never thought it was caused by hypoglycemia.

Now I would exercise and closely monitor my glucose level, then adjust my intensity when it dip lower than 100 mg/dL (5.5 mmol/L). It made the cardio exercise much more bearable, and easier to stick to it as a daily routine.

I'm baffled by your comment. I specifically recall getting some new Samsungs at work two years ago, so I got one to play with for a little. I was shocked by how janky scrolling felt. Just going through the android settings screen, there were "hiccups" and there was a clear lag between my finger moving and the screen moving. My iphone 7 felt so much smoother, although much older and "crufty", as opposed to the Samsung being brand new and "untouched". It was a then-current mid-range model, don't remember which one specifically.

And on R&D; the QC bar for software and manufacturing is much higher. Every process has validation testing. So it is expensive both in R&D and manufacturing.

Another thing is that these off the shelf CGMs don't really differ in quality to their prescription only counterparts, which have a pretty extreme risk profile (patient death or hospitalization if it spits out the wrong number). They use the same parts so those costs are inherited.

I do not know and do not care much about robotics per se, but I wish LLM's were better with spatial reasoning. If the new insight helps with that - great!

I dabbled a bit in geolocation with LLM's recently. It is still surprising to me how good they are with finding the general area a picture was taken. Give it a photo of a random street corner on this earth and it is likely will not only tell you the correct city or town but most often even the correct quarter.

On the other hand, if you ask it for a birds eye view of a green, a brown and a white house on the north side of a one-way street (running west to east) east of an intersection running north to south, it may or may not get it right. If you want it to add an arrow going in the direction of the one-way street, it certainly has no clue at all and the result is 50/50.

"Like, what if you recently bought tickets to see another summer blockbuster movie? Using Apple Wallet? And then you got this ad? It’d be completely sensible to be spooked by that, and conclude that Apple Wallet is tracking you."

I am not in anyway agreeing with the tracking of people's activities and purchases, but if you use either of the main payment processor networks (VISA or MasterCard) then your purchase history is being tracked and sold to third parties.

Any choice of wallet app, or ecosystem (ie iOS or Android) will not make any difference.

Some people do have a lot of issues with the adhesive and skin reactions. I am lucky and don't have that.

I use an Anubis, a modified Dexcom G6, (https://www.loopandlearn.org/anubis/), which allows up to 60 days of wear. Although realistically I've never gone over 25 days. This is with adding over patches as the adhesive starts to fail though. The one I'm wearing right now is on day 18 and still doing great.

After day 10-12 I also start to do daily checks with a blood glucose meter to verify that the readings from the CGM are still correct.

If there’s something you really want/need to get, I would strongly encourage asking a librarian for help (assuming you haven’t already).

I had assumed this would be an imposition and I could handle searching myself. However, good librarians can work magic, whether it’s finding the same material in another format, arranging a loan, or even buying it outright.

The ones I know also assure me this is one of the fun parts of their jobs!

There is also the option to do half bins / half grid pattern at the edge. So you have the normal 42x42 grid pattern, then on one edge there are 21x42 sized boxes. There are a number of designs that support the half grid pattern. This would reduce your maximum lost space down to 20mm, and you would still have compatibility with the gridfinity system.

> The once efficient and punctional trains in Germany have deteriorated severely in the past years due to lots of delayed maintenance causing lots of delays and even regular cancelations of trains.

The main cause (often somewhat hidden behind the term "decayed infrastructure") is that there are too many trains on too few tracks. There are many reasons for that. I think the main ones are:

* Political pressure to have more trains, without an adequate increase in infrastructure capacity (trains are cheaper than tracks and can be delivered faster). For example, political pressure utterly destroyed the reliability of the local rail system in our area, because the number of trains per hour was increased by a factor of 2-3, with only a minimal amount of new tracks (the majority of the network is still single-track). Apparently, the system worked in simulations under near-perfect conditions (no delays, few passengers, no technical problems). So let's build it! The chaos that ensued during the first few months after the network opened again made national headlines. Another example: the highly overloaded Rhine valley line between Mannheim and Basel was proposed to be upgraded to 4 tracks in 1964. In 1970, the project was scheduled to be finished in 1985. Currently the (ambitious) goal is to finish the project in 2041 [0]. The original line (270 km) was finished after 17 years in the 1840ies.

* On regional and local lines, a tendency to increase train frequency and to decrease train capacity (more trains, but shorter ones). I suspect this is also because of political pressure ("your station now has 4 trains per hour!!"), but it doesn't make any sense. A short train which can hold 150 passengers occupies exactly the same amount of "space" (blocks) on the tracks as a full-length train with a capacity of 1,200 passengers, and they require exactly the same amount of personnel.

* Privatization of DB on the early 90ies, with political pressure to be profitable. Tracks are expensive to maintain, so those parts of the infrastructure that could be classified as "redundant" were dismantled. Now they have a network with little redundancy, which is great from a short-sighted business standpoint, but terrible for reliability.

This shouldn't be a surprise. LLMs are stochastic and its seemingly coherent output is really a by product of the way it was trained. At the end of the day, it is a neural network with beefed up embeddings... That is all. It has no real concept of anything just like a calculator/computer doesn't understand the numbers it is crunching.

The company fleets are a thing of the past in my part of Europe so I didn't have them in mind when I was making my comment.

I would speculate that European fleet purchasers in other parts of Europe would be wary of buying Teslas now partly because of the current trade war stuff and also with an eye on the resale value at end of lease; its really hard to shift a second hand Tesla these days.

Naive intuition says adding more roads and lanes would finally solve the bottlenecks, right? And it does, briefly. But after a little while it's back to bumper to bumper. That’s induced demand [1]: when new capacity just encourages more driving.

Counterintuitively perhaps, bike lanes, road diets and public transport actually work better. Give people other ways to move around, and you take pressure off the road system, making traffic better for everyone. And that includes the drivers.

I've made a utility that uses LLMs to compare specifications against implementations, called "semcheck" (semantic checker). I’ve often found that even though I set up Cursor rules or CLAUDE.md files, the implementation tends to drift away from these documents. I built this utility to be run as a pre-commit or CI step to check that they are still the same.

> If it is the same as in Switzerland, the solution is in helping people get the health care they need. [...]

Switzerland SBB/CFF and the German DB can not be compared, not even from far.

The Swiss trains are amongst the best in the world in term on punctuality. Delays barely exceed few minutes most of the time. Every connection is scheduled to be done < 5min. The usage is smooth like butter and It works like a Swiss clock.

At the opposite, German trains in the eastern part are barely on time and give you an almost Soviet experience for the regional one: The trains are old, poorly maintained, like the track itself and the service suffers of it.

The only place in Western Europe I experienced train to be worst than in Germany is currently in Hungary where there were actual soviet trains.

Even the freaking French SNCF with their legendary strikes tend to be more punctual than the DB.

I do plan on open sourcing more of the code over time. I also have started working on other sites using the same algorithm implementation (music, movies, video games)

This has just been a side project over the year generating passive income. I get around 250,000 page views a day, and with ads, memberships, and affiliate links I make around $2,500~ a month.

Also, the passenger miles per unit of energy drops geometrically, as speed increase linearly. Most of the loss is aerodynamic, so you either need a hyperloop tunnel or wings to take you into the literal stratosphere, to avoid high fuel burn at high speeds, so even if you could run the train at 400 km/hr along the whole track, it would be unlikely that any operator would do so, on a recurring basis.

Heritage that is so remote that it doesn't matter anymore. Most of their ancestors left centuries ago.

I would like to see laws against constructive illegal practices, or at least an assumption that any forseeable outcome of the company's policies is considered by the court to have been the intentional outcome. Codify "the purpose of a system is what it does" into a legal presumption.

Say, Wells Fargo giving their front line staff unattainable targets for account openings, which was a somewhat deniable way to mandate that staff illegally open accounts for everyone that they interact with.

Or, a gym requiring a certain retention rate for customers calling to cancel. Predictably, this just results in the call center staff illegally refusing to cancel the gym membership, so it's tantamount to a company policy that customers can't cancel their accounts unless they get lucky.

Or airlines that are required to give you compensation, but only do so if you ask, and ask in a very specific and timely manner, for example, hotel compensation for cancelled flights.

Of course they can, though not as easily as you seem to think I suspect. Radar technology is very secret. Regardless, it’s a matter of numbers. I’m sure the Ukranians would love to field unlimited predator drones if they could. In reality, they field DJI and other commercial drones en masse because of availability. Only relatively recently have they got their own cheap mass produced drones online. These drones are also easier to destroy than a predator, so by your logic, why would they have invested in this? Wunderwaffe never wins wars, logistics do.

Earth revolves around the Sun? Let's see. In a twin-star system which one is going around the other? Let's make one of them have higher mass. Did the heavier one completely stop going around, or does it still wobble a bit? That wobble mean the heavier one is still going around their common center of mass. Also, since there is no static fixed point in the space, the interpretation of movement of Sun and Earth could be very subjective to the reference frame selected. There is nothing wrong if someone wants to consider Earth as that fixed point for some arbitrary local reference frame. Infact, a lot of calculations that matter to human life on Earth require that.

Who's never worked on a spaghetti code? Luck you.

I've worked on sever projects that had some spaghetti code. And all this started because of a lack of structure.

A well-structured application helps you avoid that mess by clearly separating concerns. One common and effective approach is using a layered architecture.

While the number of layers can vary depending on your domain, the core idea is the same: group logic by responsibility. Here's how I typically split it.

I avoid situations like this as if it was the plague but a long time ago I dealt with it for both myself and others who lost the will to deal with it.

This included both commercial and government entities. I never raised my voice, I simply made it abundantly clear that I had a nearly infinite appetite for being litigious in a very public manner if they did not immediately address the issue at hand in good faith. It was effective. In literally every case they did something reasonable and I never heard about it again, even in cases where they had been dragging someone for years.

To be clear, I would have pressed the point if they hadn’t relented. But in every case they did in fact relent. They are obviously making judgments about blowback potential when they do these things, which is terrible policy. Doubly so when governments do it, since they explicitly work for us.

I like that no one brings up the question that Bitcoin is not really decentralized. Most of the Core devs are paid by a company (iirc it was Blockstream but might've changed), and ultimately, the paycheck they receive dictates which direction the most used Bitcoin wallet should go, which dictates the direction of the project as a whole.

There were several attempts of merging important BIPs, which were rejected because some developers thought it wasn't in line with the direction their employer wanted.

I don't think cost is too much of a concern for ICEs. They are already a higher-priced option that competes with plane travel for many destinations.

You can take RE trains at virtually no cost between any two cities you can dream of, yet people en-masse still happily fork over a hundred bucks to save 3-4 hours with an ICE train.
