I am a big fan of Michael Polanyi's writings on tacit knowledge and I was disappointed to find that the author completely misuses the term.
Explicit knowledge can be codified and easily expressed. Tacit knowledge is not codified and not easily expressed. Given the details of story one (they went to a library and researched a variety of topics), that seems to clearly be referring to explicit knowledge. The second story is lacking crucial details about why it took a decade and $70m to replicate the foam, but we can assume that there was some reproducible process behind the original foam that was lost and required a great deal of effort to reproduce. Again, that would be explicit (not tacit) knowledge. The only way that it would not be is if there were individuals with a technique that was not codified and easily expressed that the original foam depended upon.
Why do you know those refer to the same individual or at least highly suspect they do?
Now you can begin to explain the rules and logic underpinning that understanding, but for every explanation you give, a counterexample can be shown where you'll go: Ah yes, but in this case... And you'll add more and more rules, yet you'll find that never do these rules and your own judgement are a 1:1 perfect match if you were to test them against yourself, you'll keep finding cases where you concluded differently.
Thus what is this knowledge that you truly leverage to make the decision? It seems that you cannot explain it fully, maybe your explanation isn't even anywhere the true knowledge you leverage, but only an approximation you made up when asked how? That knowledge is thus tacit, because you cannot express it fully to others, you won't be able to document it, or to produce a computer algorithm for it, or to communicate it to anyone else. It seems to become your expert intuition.
It turns out that Machine Learning has made some breakthrough in that realm, in that the computer can similarly learn some tacit understanding, though it may not be the same as yours, it gets closer than what your rules expressed, and it too cannot be explained back, why the computer comes to its decision is also tacit.

In fact, if I'm thinking of the right foam here (codename FOGBANK, believed to be a lithium deuteride aerogel), the problem was even worse. There was a contaminant in one of the original raw materials (acetonitrile, if memory serves) that turned out to be essential to the whole process working. But nobody in the original program knew this contaminant was even present, much less its importance, so of course they didn't document it. Not explicit knowledge, not tacit knowledge, just an unfinished R&D job.
At CNN our initial ML application is around personalization (ie article/video recommendations). While this is our main focus, we are exploring other applications. Eventually my hope is that we are able to provide tools that assist the content creators.
At the Navy, our best usage of ML is simply GUI scraping and figuring out the default action set for new hires paperwork. it basically is a screen macro that screams through forms. Took days before now takes 15 minutes. really dumb, but simple and useful in a bureaucratic 300k strong org, with possible real ML in the future for highlighting possible actions instead.
We've run into some issues with getting AWS Batch to play nicely, though I wouldn't say it is Metaflow specific. Initially we did quite a bit of troubleshooting the Stuck in RUNNABLE errors. We sometimes have issues with batch jobs that can't be satisfied by our compute environment causing other jobs in a queue to be blocked.
There are other small issues, but overall our ML engineers are very happy with it as a tool.
my 2 cents.. I've done a decent amount of work in Cloudformation before working with Terraform, and I generally find it to be far more developer friendly to work with. It is easier to organize and refactor and the syntax is more readable. For me the only negatives are: 1) its not 1.x yet, so you have to pay attention to breaking changes between versions 2) remote state of the infrastructure isn't handled for you like in cloudformation. Neither of these have outweight the benefits for me.
The XEGS was my first computer. My parents bought it for me when I was 11. I later got a floppy disk drive and a 300 baud modem. It honestly felt magical to me. Rescue on Fractalus was one of my favorite games. The light gun was not as good as the NES one, but I still had fun with Bug Hunt. I really enjoyed the Infocom text games, though I think the feelies were the best part of those. Later I discovered Ultima IV and played the heck out of that. I had my first experiences in programming with it. I would read the manual for fun and typing in programs from Antic. I eventually started asking my parents for an Atari ST but ended up with a second hand IBM AT.
Also offtopic, but my 12 year old is obsessed with Hytale.. Loves to read the blog updates and watch the videos and can't wait to eventually play it :)
Haha same, admittedly I don't have a child, I am the child, I can't wait to get into Hytale and work on mods, servers, whatever. Hypixel is singlehandedly the reason I got into Minecraft and Minecraft is the reason I ended up learning Java. That Java knowledge has earned me a respectable income as I go through college. I owe a lot to Hypixel/Studios man :D
Based on internet it seems zerowater filters are much more effective than brita, but they cost a bit more to run (because, well, they filter out more stuff).
Hmm I got to the conclusion that zero water was way better at filtering out smaller chemicals like lead. I’m still think both types of filters are good for pfas. Zero water could be a little better though.
I could still be wrong. It was hard to find any good studies or tests last time I looked into it.
"Both granular activated carbon (GAC) and reverse osmosis (RO) filters can reduce PFAS substances. Both systems provide less water flow than a standard water faucet."
I used http://ohlife.com/ until they shut down. After that I just switched to using a Google Doc. The service mostly just provided me a daily reminder, but after you get into the habit it isn't hard to keep it up without that.
I've lived in ID and MT (bordering BC and Alberta) for most of my life and people mostly say canadian geese even though I've heard that canada geese is preferred.
I agree. I only have ever had one person correct me on this, who was, incidentally, Canadian. It's rather infuriating because the Latin name is literally 'from Canada'...which we already have a term for(Canadian). If anything, it feels like Canada Goose is a bad translation that people stick to.
