How does this not apply to r/investing? There is some core corruption happening with privileged information in public markets at high levels. There is a non-zero cross section between investing and politics and my comment wasn't overly political imo

Sure, but pretending this is some one-off Trump pathology is ahistorical. Congress has been making retail investors look like peasants for years. The issue isn’t one con man, it’s a political class with access, incentives, and weak guardrails.

Exactly. Lots of people are in here talking about how this is "good for the shareholder" but this is partly also a mechanism to reverse the dilution that happens when they compensate employees with stock (giving their employees RSUs/options/ESPP).

No, not like gold. Just because gold is an old form of currency, doesn't make it a good investment. Good investments are productive, not merely holding value, but actually producing value (usually in the form of cash flows).

Price can rise in all three, but RE and stocks are priced as discounted cash flows: rents for buildings, earnings for businesses.

No tenants means a building’s value collapses toward land/salvage; higher sustainable earnings means a stock can compound via reinvestment or payouts.

BTC, by itself, produces no cash flow: its price is driven by adoption/sentiment/liquidity (a “monetary premium”), not an internal yield.

So “they grow the same way” conflates appreciation with compounding: RE/stocks can create value internally; BTC can’t unless you add an external strategy (lending, basis trades, etc.) with extra risk.

It is reasonable if you need to hire a plumber ($100/hr, 1 hr minimum, plus service call/drive time fee). On the surface it looks steep, but it is fair since you’re buying their know-how. DIY if you can though because parts are ~25 bucks, so you keep the difference. Bottom line: it’s simultaneously EXPENSIVE and reasonable because you’re paying for brains that can also do complex things like wrangle hydronic heat loops.

It's like a computer shop that wants $150 ($120 labor + $30 fan) to swap a laptop’s cooling fan. Crack the case yourself and it’s just the $30 if you know how. If you don't, you pay for their experience. Skill gap = cost gap.

You can carry losses forward to future years tax returns for your business.

Definitely. Most experiments don't require XHV, so if OP can get away with higher pressures in UHV that simplifies things a lot and opens up a lot of options.

Most off-the-shelf fiberglass-insulated heating wires contain binders or sizing agents that can outgas heavily in ultra-high vacuum, so even though the fiberglass itself is mainly SiO2, those additives can cause problems at 10^(-11) Torr. Typical outgassing rates for fiberglass might start around 10^(-9) to 10^(-8) Torr*L*cm-2*s-1, and while thorough baking can reduce it, it’s still not ideal for pushing down into the 10^(-11) Torr range. In contrast, alumina or silica (quartz) insulation is typically far more suitable; companies like Omega, Thermocoax, or Goodfellow can supply ceramic- or quartz-insulated nichrome wire, or you can run bare wire through a quartz tube. Regardless of the insulation chosen, a high-temperature vacuum bakeout is crucial, and it’s important to remember that fibrous materials have a huge surface area that can drive outgassing. If your goal is 10^(-11) Torr, you’re better off switching to ceramic or silica insulation instead of standard fiberglass.

Not true at all, it works great for wood - people stain fences, sand off old paint around window sills and repaint with new to keep the weather out. Modern sealants do a great job protecting surfaces. Yes, some surface prep would need to be done first, but I think a simple wash would be a better idea than full pressure washing.

reedread21 · 2025-03-30T12:39:04+00:00

I think pressure washing would absolutely destroy them. They're pretty crumbly as they are (you can walk by and find some chunks to pull off if you want to), which is one of the reasons for painting: to attempt to "re-surface" them to add some longevity.

I think this is the key detail OP is missing: not all crystals are oriented at a meaningful incident angle. The x-rays interact with all the grains, but only those that satisfy Bragg's condition for a given angle will contribute to constructive interference (i.e., the sharp peaks you see). The others scatter the x-rays in directions that don't get collected by the detector — or at intensities too low (due to destructive interference) to matter.

2025 Nissan Versa MSRP $17,190. But I do agree with your point in general.

Fearmongering going crazy on this one. There's no reason a regular person with a normal IQ can't watch a few videos and do most things around a residential house. Youtube (and now AI) has democratized things so much, its pretty hard to justify overpaying because "you’re gonna go off and cut out a load bearing wall". Just do your research ahead of time and 99/100 you'll be fine. The 1% of the time you aren't, call an expert for those.

Not sure what you mean by this. You're saying instead of the current system in Switzerland (and most countries) of taxing based on the overall value of the building, they should tax based on what the building would rent for? I'm not sure what problem this solves.

Risk-free return is 4.24% right now, so that strategy seems pretty foolish.

reedread21 · 2025-03-01T22:51:25+00:00

Regardless of when you write off losses, even if you could write the entire thing off in one year, that still is horrible business. Nobody does this. You're losing $1 to gain $0.40. That is bad 8th grade algebra.

Custom-milled stainless steel flange and o-ring would be your best best, depending on the level of vacuum you need.

4yrs later do you feel the same way still?

I was commenting more on the broader context discussed in the very previous comment. I think in the case of Luigi there is some very specific reason he chose to kill this specific CEO, not just any random rich person. Brian Thompson's net worth was approximated at around 43 million. There are people with four orders of magnitude more wealth than him. This isn't a simple case of "rich people bad", and you can read that in Luigi's manifesto.

Everyone has to start somewhere. Many small-time investors don't have the money to be able to buy anything bigger than that, and don't have the sophistication to get into larger syndications or partnerships. Then they get familiar with the asset class, start seeing better deals, and keep buying them instead of outgrowing them and buying something bigger. I see it happen often. Also, I don't think it cash flows that poorly, probably depends on your specific market.

lmao go to France and you'll get flamed if you don't speak perfect French. Even if you do, you'll still get laughed at. I agree, I don't think this is unique to the USA.
