> Same reason why they stared iodine to salt… because people were having mental development issues.
This is not directly related to the topic of Fluoride, but Iodine was actually initially introduced to reduce goiters. The mental benefits were a wonderful, unexpected side-effect. Studies have put the effects anywhere between 8-15 IQ bump for populations that were Iodine deficient. Pretty jaw dropping when you think about it.
About 2.5% of the population has an intellectual impairment (if mean IQ is 100, and SD 15, 2.5% have IQ less than 70 the WHO cut off). Of this 2.5% some will have social/adaptive impaitment similarly 2SD below the mean and have an "intellectual/learning disability".
Move that mean down one SD (15 IQ points). And now OVER 15% of the people meet the intellectual impairment criteria.
Put it another way, due to the shape of the normal distribition moving IQ down 10-15 points amounts to 2-3X increase in the number with abnormally low IQ.
Cut to the modern era, where fewer and fewer jobs are available for those with intellectual impairments, and the world requires more and more technical prowess and the situation is far worse than the figures appear.
> The interesting plot twist is that Dendrite development has ended up increasingly focusing on embedded matrix server use cases - particularly to power Peer-to-Peer Matrix, where clients require a server to be embedded within them. So while Synapse has ended up increasingly focusing on large-scale deployments, Dendrite has ended up pursuing smaller instances (which is ironic, given originally it was meant to be the other way round!).
This reminds me of the general idea behind Tripwire[1] for macOS. I last looked into it back in 2005 (we went with other approaches), so it may have changed since then, but it monitors for changes, and allow you to revert them or deploy them to other computer (as in a lab, etc).
Those things are tanks. Perform a maintenance kit on one of those, and it's good for another 150k pages no problem. The main thing that needs attention is the rubber feet that pick up the paper get dry. Some rubber rejuvenator on a q-tip goes a long way.
I have a 4050 for home, and I have no reason to doubt its future longevity. :-)
The firmware, though, is ancient (telnet, and a web interface that requires IE 5 IIRC). Now if there was open source firmware for these things...
Sadly, my experience with FLEXlm has been far from fascinating. Matlab uses it, and Matlab has some weird license types (that we use) that don't map well to FLEXlm, so they approximate it in odd ways.
I build (internal only) Debian packages for Matlab and FLEXlm, and admin the license server. I've seen far more of FLEXlm than I care to.
Mathworks made the mistake once of asking for my feedback about their product, from a sysadmin's perspective. They received about three earfuls from me, about half of which was dedicated to my disdain for FLEXlm.
FLEXlm seems simple on the surface, but has poor and outdated documentation (even once you find and read through the 300-400 page tome that's floating around) and is a pain to debug when under fire.
We have it running well enough now, but the road to get there should frankly embarrass those who ship (and/or rely on) the software today. Frustratingly, Mathworks' response to my feedback largely boiled down to "it's 3rd party software, so we can't do anything about it." As if FLEXlm were a force of nature, and there were no viable alternate models for physics. Not a good look.
I use zfsnap.[1] It's been forever since I've worked on it (hence why it's now "archived" on GitHub), but it's stable for my use and I use it on all ZFS systems I manage.
I would like to second this recommendation. I have found "Beginning Portable Shell Scripting" to be invaluable --- and far more comprehensive than I expected given the "Beginning" in the title.
I highly recommend it (and the POSIX docs) to anyone who is is interested in portable shell programming.
Most of the consumers so far have been neuroscience researchers and statisticians, but we do hope (and think) that there's value for a wide variety of interests.
There's a bunch of different data, but the highlights are fMRI scans of people watching and/or listening to the movie Forrest Gump, eye tracking, and detailed annotations of the movie. We are also about to begin acquiring simultaneous EEG and fMRI.
I personally have no problem staying under $100k; I live in Germany and work at a university. But imagine if you lived in Switzerland or Norway. Somewhere with a high cost of living and with a currency that is very strong vs the USD. Then it doesn't take much to go over that 100k.
And even though I don't have to pay US federal taxes (being under that $100k), I still have have the file state taxes, federal taxes, and an FBAR. Every single year. The time and effort is an annoyance, but what bothers me most is the principal. I don't live in the US; I don't use its services; and still, every year, I have to allocate a weekend to provide them with every single detail of my financial life.
