I can't speak to the physics but I've done cold water dives, and if you prime your wetsuit with a thermos of hot water, that envelope of hot water stays in your suit for a surprising amount of time
I wrote a Ruby gem to address this problem of hiding sequential primary keys that uses a Feistel network to effectively shuffle int64 IDs: https://github.com/abevoelker/gfc64
Kinda similar idea to this library but you're encoding from an integer to another integer (i.e. it's format-preserving encryption). I like keeping the IDs as integers without having to reach for e.g. UUIDs
It's really an indictment of how far HN has fallen to Redditification* that you see this kind of low-brow ignorance so prevalently and so often.
Yes, the greedy doctors who are lucky to get a couple hours of medical coding training when they start practicing and get needled constantly by their billing department for underbilling actually have "years of learning" in how to screw over their patients.
Maybe they mean the man-years of time wasted arguing with insurance companies, shuffling around medications and care plans to please them, evenings and weekends spent in the EHR finishing up patient notes (because there's no time to get them done during the working day with 20 minute visits) and correcting and signing off on patient care for the PAs and NPs (cold-heartedly taking 100% of the malpractice risk burden for the nurses who actually care about "healing").
I'd encourage people this far gone on the deep end of visualizing physicians as hand-rubbing greed machines to spend a day actually shadowing one. Because you are very ignorant about how they spend their time and the amount of effort they put into caring for patients in spite of continual soul-crushing roadblocks put in their path.
* Yeah I know it's against site rules to say but I don't care it's true
He seems to do an annual "update" video from wherever he's at, about minutiae of whatever he's working on at the time. It used to be QuakeCon keynotes[1] when he was at id.
Take heart, even if you weren't shadowbanned, with a young, low karma account your first comments on most subreddits would get automatically modded as spam by Reddit's dumpy spam filter anyway.
As a primarily Ruby dev I'd prefer the AI/ML ecosystem not be split-brained between two languages that are semantically 90% the same thing. Just learn Python and integrate the models into your Rails (or whatever) apps.
Just using the file system is inadequate for some reasons that TFA mentions. For instance, returning gzip or Brotli compressed versions of resources, or returning HTTP 301/302 redirects for certain requests.
Also if you use CloudFront be aware you'll be paying for bandwidth, so if one of your pieces goes viral (or you're just a popular writer) the cost can be surprisingly high (over $50/mo).
Which only looks at greenhouse gas emissions (and only then compares grass feeding to grain feeding), and does NOT consider the effects to local groundwater, surface water, or air quality from CAFOs.
Besides things like frequent manure spills that pollute surface and groundwater, children living near these CAFOs have elevated rates of asthma.
The piece is very focused on greenhouse gases and the benefits of "economies of scale" but doesn't say a peep about the meltdown of our consolidated food supply when the pandemic subjected it to supply shocks.
We don't? Didn't Zuckerberg just admit on Joe Rogan that during the last election all the major media companies were briefed by feds that were was a big "misinformation" news piece incoming, so that when the Hunter Biden laptop story finally dropped, they all censored it, sight unseen? Therefore it seems all the big social media tech companies have no problem with rubberstamping gov't requests for censorship.
They almost made it glaringly obvious when they tried to roll out their Disinformation Governance Board, which fell flat.
This shortcoming becomes immediately apparent when you try to use certain VMs, like from Vultr, which are IPv6-only with no CG-NAT. You can't clone anything or fetch any release binaries at all.
I'm assuming it relates to operations management but I imagine this type of person not accidentally taking a little shine from the name collision with spec ops soldiers and Matrix movie characters
