"Causality: Models, Reasoning and Inference", https://a.co/d/6b3TKhQ, is the technical and researcher audience book.
Then I'd go to a restaurant and when reading the menu, I'd start swiping at the paper or vinyl menus like it was a tablet. It's a curious phenomena to have that brand new tablet gesture overtake decades of behaviors and perceptions with real paper.
Kudos to Apple, I guess.
Solace in particular is magnificent.
One had a dramatic improvement very quickly, where one or more of the Ws was resolved. Another had the spinal tap indicating she was a good candidate, but the shunt is still not resolving all the issues even after 2 months.
Do you have any clinical experience with the success rates of the shunt?
I’ll check out the ones with custom molds. Thanks for the suggestion.
They work really well to dampen loud sounds and, importantly, they let conversation through, though it sounds muffled. But you can feel the difference. They are much better than using foam ear plugs, which muffle everything.
I used to go to a lot of concerts without any ear protection, when I was young and dumb. I REALLY wish I had these things back then, since I've acquired mild tinnitus as a result.
Now I carry them on my keychain all the time and use them even in restaurants and bars or whenever I'm some place where I have to speak at an elevated level.
Anyway, antibiotics causing damage like this sounds like it could have triggered an auto-immune problem. If so, then that is a large quagmire.
That is, I can see how to solve a problem in the common case. But as I code, I encounter the myriad of error cases, exceptions to the common problems, and especially the interactions of all these. Then add in performance considerations and the complexity can multiply quickly. The long-tail of those errors and exceptions can be very time-consuming to solve, so the mean is likely to be way off.
It's obviously much easier to estimate when you're experienced with a problem space. This should mean that you know how to solve a particular problem as well as the likely exceptions (non happy-path) you'll encounter.
If you're experienced with the domain, you can fit the relevant partial solutions in your head and more accurately judge what could go wrong with your code. But more generally I think this is similar to solving problems in other domains as well, such as architecture, building a car, or anything with many moving parts. These domains do not usually have loosely coupled sub systems.
I've taken 5000 IU/day (with vitamin K2) and have my blood levels tested every year. I don't remember what my serum levels are but they were on the high end of healthy individuals. Last I checked, my levels matched what a person reaches who spends the day in the sunlight, perhaps like a outdoor worker.
Whatever you try, if you have an annual check up, you should get you blood levels tested to verify you reach sane levels. I think most studies and articles fail to mention how dark the subjects are.
But I'm stealing the last line on reasoning about software, "If Tony Hoare were not alive today he would be turning in his grave."
Needs an entry for Crypto. Used to be cryptography, now it means ponzinomics, or something...

Their website docs suggest that you can build static libs that could be linked to an iOS app. But I haven't had time to try this.
[MITCBMM - Center for Minds, Brains and Machines] https://www.youtube.com/c/MITCBMM - great lecture source for AI, cognitive science, neuroscience.
[Steve Brunton] https://www.youtube.com/c/Eigensteve - great lecturer on applied math for engineering and computation science. Like an advanced Khan academy
[The Royal Institution] https://www.youtube.com/c/TheRoyalInstitution - science talks for lay audiences, like Ted Talks but more advanced.
[Mathologer] https://www.youtube.com/c/Mathologer - misc math topics, like 3blue1brown. This guy is quirky and funny and good at explaining some advanced math topics.
[Numberphile] https://www.youtube.com/c/numberphile - topics on mostly math, but also CS adjacent.
The timer is MUCH better than the built in iOS timer. It has pleasant (less jarring) bell/gong sounds and customizable presets.
It also keeps track of your sessions which is useful as a subtle nudge to keep a routine practice.
It’s not essential but is nice, useful and free.

Many large certificate issuing orgs run timestamping authority servers. Tools like Java jarsigner, Adobe Acrobat, and many other tools are designed to work with them. Search for "rfc3161".
I like the style. It reads like something that Spock, Commander Data or the HAL 9000 would say, which IMO is a good thing.
So to be statistical about it, the difficulty level for him was at the edge of 1 standard deviation of the mean of his capability. Maybe that's enough margin that he could detect when he's really in trouble.
I was always somewhat concerned about the abundance of critical raw materials for ARC or other fusion projects. I had assumed that the rare-earth elements in the REBCO tape, e.g. yttrium, would be constrained. I didn't suspect that beryllium could be a limiting resource. But I wonder if the lack of supply is related to true scarcity or just to a lack of a profitable market currently.
These are all questions I'd want to ask domain experts in mining and fusion.
But I agree that fission would be a better solution for baseload, at least for the next 10-20 years. If only newer modular designs were actually approved...
In short, from my basic understanding, there are quite a few additional major challenges involved with fusion power generation. e.g. After creating net-positive fusion, the heat must be efficiently extracted without stopping the reaction. Also tritium must be continually extracted from the FLiBe (fluorine-lithium-beryllium) bath that stops and collects neutrons and extracts the heat.
Since I'm a total novice in all this, I don't know if these require incremental innovations or major advances. But from the video, the problems mentioned seem to be more tractable than achieving fusion ignition or Q>10.
The game changer here is not very new reactor designs, but cheap high performance high-temperature superconductors that enable very high field and therefore much smaller size.
Other fusion work, like ICF or the LLNL laser fusion or Lockheed or General Fusion all seem to be built on designs that are far less understood and less Q performance so far.
And so far, the company, CFS, has been achieving their milestones for the performance of their magnets. The HTS magnets and coils is the main ingredient that the startup is optimizing for. Sometime in the last year, they implied that their Qplasma was much better than they minimally hoped for. I think they achieved Qplasma > 10, but Dennis was keeping the details proprietary.
From all the talks I remember, they are targeting power on the grid with the ARC reactor by 2035.
Edit:
This is the best recent video I've seen, about SPARC and ARC. Jumped to 2:25 for Dennis Whyte.

It's targeted to MechE students and gives a lot of details about other aspects of a potential ARC reactor design, e.g. how to get the heat out.
It's marketed as a gaming keyboard, but it's fantastic as an ergo. It's the best keyboard I've ever had. Previously I used the Microsoft ergo, forever.
Another subtle consideration is the placement of the Alt/Option keys next to the space bar. A deal breaker with a lot of other split keyboards, like the Kinesis, is that they have space bars that are too wide, so the modifier keys are too close to the outside edges. But the Raise has a compact space bar, so your thumb doesn't need to contort as much to use them. The software to reprogram the layers is decent, somewhat obtuse, but easy enough for basic remappings. For example, I reprogrammed some letter keys to be arrow keys when pressed with a modifier.
Oh, the only downside so far is that it really could use a row of function keys on the top, to mimic the macbook laptop layout.
They haven't released a keyboard tilt/tenting kit yet, so I had to make my own to give the inner edges a height of about 1.5 inches. Also, I place an elevated magic trackpad right in between the two halves. It's a frankenstein keyboard-mouse setup, but now it's very comfortable.
