Post printing a very small amount of time with sandpaper (or acetone for certain materials) would smooth things out. It wouldn't work well for small details though.

As a very rough ballpark, hard drive cost was around $1/GB, putting a single copy of everything around a half million dollars. Honestly quite a bit less then I expected for back then. Of course there are tons of other costs, but still

For what it's worth, I saw the same in a hot market in Iowa. I was taken aback, because generally speaking we saw a much less bad 2008-era than other places across the country. We have particularly low unemployment, which could be le

Oh yes, I was only covering federal taxes. To my knowledge, the general structure in most states doesn't matter. I don't know of any states where income taxes are partially paid by the employer and partially by the employee (lik

You are in the US as well. We have FICA (social security, medicaid, Medicare) of which half is paid by the employer and half employee. If you hear "self employment tax", that's typically referring to the fact that you're

The thing that shocked me the most is that it's economically viable. The tolerances are so tight, the machines so expensive, the volumes so big, that the math works. If I had no idea what semiconductors were and you just sat me down

Not sure I follow. The 99.8% is just an example number. If one machine messed up really bad and had just 50% yield, all other machines would need to do far better in terms of overall quality to achieve 36% yield. Of course every single mach

Sorry if that came off abrasively. avs733 mentioned everything is on a different scale in semiconductors and I forgot how long it took me to grasp that. In school (industrial engineering) we talked about length and thickness tolerances bein

Yes it is. The 99.8% hypothetical number is on a per operation basis. Depending on the layers and complexity of the chip, the ballpark number of operations might be 300-1500 (lots of hand waiving here). The gist of that part is meant to sho

I spent some time working in a fab. Nothing is cheap, competition is tough, yield is everything. 99.8% yield on each step of a 500 step process is good for 38% overall recovery. These events have been shown to be very rare, and the costs wo

Whether the funds would be removed wasn't explicitly clear, but in a roundabout way, you brought up a good point. 401k's typically have a select 20-40 funds you can choose from, and this won't necessarily be available to GP.

Admiral shares come in at 10k for most of their funds. E.g. VTSAX has the 0.04% ER and a 10k minimum, while the Investor class is at 0.14% (VTSMX). https://investor.vanguard.com/mutual-funds/fees > Admiral Shares &
