For PPE: an effective respirator is not that expensive, should be wearing them and safety glasses for sanding as well. Only extra PPE you really need for acetone smoothing is some nitrile / latex gloves, and those are fairly standard in shop / art environments anywho.
Also, MEK, Methyl Ethyl Ketone, apparently smooths PLA out quite well too, but if you can print in ABS I would already be doing that for finished products anywho.
while writing documentation in Markdown, I almost always have the preview open in split-screen in vscode, not because I need it, but mostly to make sure that the other people reading my work have a good experience.
Right, so if I drink straight-up HFCS it'll be fine provided I also stick trace quantities of antioxidants and pollen fibre into it? But if I don't do that, it'll be terrible for me?
Honey is formed by the hydrolysis of the complex sugars in nectar into fructose and glucose. HFCS (high fructose corn syrup) is formed by the hydrolysis of cornstarch into fructose and glucose. They're chemically extremely similar, except for differences in the ratio of fructose to glucose, and for small traces of other stuff (pollen etc.).
The statements I was responding to claimed that "until recently it was very expensive to get sugar" and then "honey is not the same as refined sugar". Honey is refined sugar formed by the same process as HFCS[0], and some hunter-gatherers get a surprisingly high amount of daily calories from it with seemingly little impact on their health.
[0] From a different precursor, but the general process of breaking down complex carbohydrates into simple sugars is the same, and so is the output
Yes, but to be fair the reporting is incomplete because the Boeing-maintained records of the maintenance were incomplete in seemingly-deliberate ways. So... we just don't know. At least one, plausibly two bad guys there.
As far as I can make out, Spirit employees (probably with the knowledge and tacit approval of management, because that's the way these things usually go) found a loophole in the record system that allowed them to avoid triggering QA checks. Boeing has blame for creating a system with such a loophole, or failing to find it before it was used, but it was Spirit personnel who actually used it.
IIRC from one of the whistle-blower accounts, the main issue was that the Boeing computer system only had an option for fully removing the door, which wasn't done, only a partial removal to allow access to the parts needing work. There was then a disjoint between the Spirit work system and the Boeing one which resulted in someone saying "fuck it" and skipping it.
It is amusing to me in a comment about a particular group only seeing hammers and nails that the presented solution focuses specifically on a singular technology / implementation.
I literally covered the "driving with traffic" issue in the comment you are responding to. Driving at higher speeds isn't inherently safer, it is conditionally safer.
If the speed limit is 60MPH, and everyone is driving 80MPH, it is safer to drive 80MPH than to drive the speed limit and get hit from behind by someone going 20MPH faster than you.
Of course, every single person driving 80MPH in this scenario is breaking the law (in most states this is reckless driving), and making the road less safe for everyone, especially motorist obeying the law. The status quo isn't great if we just accept that everyone has to drive recklessly because the people around them are. That's a problem in need of a solution - a solution that can include mandatory speed governors and geo-fencing.
If you require governors and geo-fencing, the condition of "everyone is driving 20MPH over the limit" doesn't exist, because everyone's cars will be capped at the legal speed limit. Driving with traffic will only entail speeds up to the speed limit, not up to the fastest speed that drivers around you feel like driving.
Thus why I said that regulators would have to go all-in on this technology, rather than allowing slow roll-out, because a transition period would make the roads more dangerous allowing older vehicles to drive recklessly fast while not allowing newer vehicles to safely drive according to road conditions (created by reckless drivers).
If everyone is going 80 mph, then being the one driver actually obeying the 65 mph speed limit puts you and everyone around you in MORE danger.
Would it be safer for everyone to be going 65 mph? Absolutely. I'm definitely not disputing that.
But speed differential is more dangerous than speed itself.
EDIT: To be more accurate, speed differential makes crashes more likely, but speed overall obviously makes the crashes more likely to be fatal. Whether it's safer to go 80 when everyone is going 80 to reduce the likelyhood of a crash, or if it's safer to go 65 mph to reduce the severity of a crash if it happens is very debatable, and I'm not sure there are good enough statistics to back up either claim.
One thing to keep in mind is when is the breaking point? If one person drives 100mph, should every single driver match that speed? What about 90? 80? What is the cutoff?
There is a reason there are speed limits. They are the cutoff.
I've found that many drivers feel uncomfortable being passed by other drivers. They translate that discomfort to being "Less Safe." Despite the fact that they are objectively much safer traveling at slower speeds. Not many people appreciate the difference in fatality rates between 65 and 85 mph. Fatality rates go from 20% to 70%. In addition, your ability to control your car in a minor collision at high speeds is heavily compromised.
I've read both of your links, and both fail to address one scenario and a question regarding it:
If EVERYONE is driving 80 mph, is it more dangerous to be the one person deciding to drive 65 mph?
Most studies and statistics either focus on speed alone OR being the ONE person driving 80 while everyone else is driving 65.
Speed differential increases the frequency of crashes, and overall speed makes crashes worse. I posit that the best crash is the one that doesn't happen, so reducing the frequency of a crash by going with the flow of traffic is the safer option.
