Next Trump will propose helping America's farmers out by ordering all the sparrows killed.

I've been through it myself; I know how painful it can be. Just remember that as bad as today might be, it's the worst pain it's ever going to be. Each day is a bit better than the one before.

I'm getting a real big "Mao's backyard furnaces" vibe from this whole situation.

Congrats! And hope for a quick recovery.

I've ordered DIY before. I'm an international supply chain and logistics expert!

It will never be more efficient to 3D print a part that can be made via casting or injection molding. An injection mold takes seconds to make a part that would take a 3D printer many hours. It's the old Swiss army knife problem. A purpose-built tool will always perform a task better than a general-purpose one.

They need to run a former Democratic primary candidate who has the bona fides to truly win over Republican voters. Dems keep trying to appeal to Republicans, but it never works. They need a candidate that the right will finally accept.

Say hello to 2028 Democratic presidential candidate David Duke!

Thanks to sprawling American car-dependent infrastructure, not even Bigfoot can walk to places anymore.

Ultimately any retirement system suffers from these weaknesses. You can have a retirement system based entirely on universal generous state pensions; it won't matter. When the economy takes a hit, the state is less capable of generating revenue.

Exactly. For middle class folks who still have to rely on the stock market for retirement, the best option is to just buy dumb index funds and hold them til retirement. You aren't going to be able to outsmart and out time the actual Wall Street traders who have PhDs in mathematics, access to microsecond trading, and a trading bankroll of billions. If you need to rely on the market, buy and hold is the only sane strategy. At least then you minimize the number of trades you make and the chances for the snakes to screw you over.

If you want real investment advice: no. If you're investing for retirement, and you're not near retirement age, you have decades ahead of you before you need these funds. You know those people who "lost everything" in the 2008 recession? Sure, some people lost their jobs and were forced to burn their retirement savings just to keep the lights on. But far more lost money because they sold when the market was in the toilet. The market did eventually recover, but the timing of the recovery couldn't be predicted in advance, so they lost out on much of the recovery. The market went back up, but they still had their 401k sitting in cash. They lost money on the dip, and then they lost money again on the upswing.

Also, keep in mind that Trump's policies mean that cash savings will be far more vulnerable in this crash than in the 2008 crash. At least in 2008, the inflation rate was basically zero. Cash didn't lose much value just sitting in your savings account. But Trump is trying to weaken the dollar to make imports more expensive and US exports more appealing to foreign consumers. And Trump's policies are expected to be rather inflationary. Cash is no safe haven right now. You could try to move your assets to foreign currencies and companies, but this crash is global. The US set itself up as the linchpin of the global economy after WW2. If the US stumbles, everyone stumbles. The only country that won't be hurt much by this crash will be North Korea. But there really aren't that many investment opportunities for foreigners in the hermit kingdom.

It sucks, but at this point you should just ride it out. If you still have decades till retirement, just ignore your retirement balance for the next few years. Just ride it out and remember that you're investing not for today, but for decades in the future. Or consider the parable of Bob, the world's most unlucky investor.

The "crash it and buy the dip" strategy only works if you're confident that asset prices will recover after the crash. There is no guarantee that's the case. Trump is doing damage to the US economy that won't be easily recovered. Even if free and fair elections happen in 2028. Even if a Democrat manages to win. Even if they reverse every one of Trump's economic policies. Even if all of this is true, Trump is doing damage that may not be reversible.

Let's say you're a company overseas that sells a lot of products in the US. You go to great lengths to make your products compatible with American markets and appealing to American consumers. Think of a company in China that makes products for Walmart stores. Walmart works closely with manufacturers. If you want to sell something at Walmart, you need to go through their processes, make products to their specifications, etc. You have to make custom versions of your product just for Walmart stores. Walmart is such a large market that it is worth it for manufacturers to do this, but it is a long and expensive process.

Imagine you're such a Chinese manufacturer, producing products specifically to sell at Walmart. Now you get hit with a massive tariff. Suddenly your Walmart sales drop in half or more. You've spent millions tailoring your products to the needs and preferences of Walmart, and now that investment is just gone. Poof. Millions lost in an instant.

Now imagine that after 2028, all the tariffs go away completely. Are you going to be so eager to go through the process of interfacing with Walmart again? Would you invest those millions again, knowing that in 2032 another Republican arsonist can roll into office and put the tariffs right back up again? I think you would rather spend your finite resources tailoring your products to the consumers of saner countries.

Or consider US arms manufacturers. They're losing a fortune on cancelled arms sales in Europe and other allied countries. The US is now showing itself to be an unreliable ally. As long as the US was a rock-solid member of NATO, countries didn't mind buying F-35s from Lockheed Martin. But if the US's allegiances can swing wildly with each election, that's no longer the case. The F-35 is a modern fighter that runs on American software. Ukraine just found out that a lot of American tech can be remotely disabled at the flip of a switch. Even if a Democrat wins in 2028, and they're the biggest NATO supporter in all of history, would you trust the US? Or would you rather buy something made in Europe that is less risky? If you're Poland looking to buy a jet fighter, one from France probably looks a lot better than one from the US right now. At least France is unlikely to suddenly decide that Putin is great.

Or the ultimate issue - the US's status as the world reserve currency. Trump is currently setting fire to the global trade order put in place after WW2. Remember. This system was built by the US. We dictated the terms of it. We built a system that gave us immense profit and benefit. And Trump is slaughtering the goose that laid the golden egg. The US gains huge economic benefits from being the wold reserve currency, and Trump is in the process of ending that. That isn't something that can just be regained, regardless of who is sitting in the White House in 2029.

This is why I am very skeptical of the narrative that billionaires want Trump to crash the economy so they can buy cheap assets. Buying cheap assets during a crash is only a windfall if the prices of those assets go back up at some point. But Trump is doing a lot of damage to the US economy that simply won't be easy to repair, regardless of what happens in the next election.

 

A question for the home brewers out there who know a lot of chem. One of the biggest problems with home brewing is verifying that the raw active ingredients you order are in fact what you ordered. You order estradiol enanthate or some other ingredient from a manufacturer, and an unknown white powder shows up at your door. There are crude testing methods available like the melting point test, but they are limited. There are also testing services like janoshik out there, but they're expensive and involve shipping samples internationally. With shipping, testing a single specimen with a service like janoshik can be $100-$200.

I know dedicated dedicated optical spectrophotometers like these exist. While accurate, these units are big, bulky, expensive, and not really suitable for the kinds of simple compact labs home brewers use.

I stumbled across this video describing a little cheap spectrometer available from a small shop in China. The videos I can find of it only show measuring the spectra of various light bulbs. However, I'm wondering if it's possible to use such a device to measure the purity of specimens of estradiol enanthate and other HRT medications.

I'm not an expert in spectrometry by any means, but I am aware of the general process. With a dedicated desktop spectrophotometer, you create a calibration/standard curve by measuring the spectrum of solutions of different concentrations prepared with a sample of known purity. Then you use that curve to measure the concentration of your unknown specimen.

But the big desktop units are designed from the ground up to do this. You place solutions in dedicated transparent cuvettes. Everything is in a single fixed unit designed for this purpose.

But is it possible to do something similar using just a simple spectrometer? Could you maybe buy such a spectrometer, bolt it to a surface, and cobble together some means of holding a cuvette? If you could fix the cuvette, light source, and detector a fixed distances from each other, then perhaps you could use such a device to cobble together a basic simple optical spectrophotometer?

Would this actually work? My thought is that while this wouldn't be the most accurate spectrophotometer out there, ultimately it doesn't matter. The goal of testing raws is not to measure their concentration to four significant figures. The goal is simply to verify you have the right compound and to ensure that it hasn't been cut with fillers. Even if such a setup had an error rate of a few percent, this would still be perfectly acceptable for raws testing.

I hope I'm explaining this question well enough. I'm really just wondering if a simple cheap usb spectrometer like this one here could be used or modified into a device that can measure raws concentrations.
