dfsegoat··on 10-sec 1-leg stance duration predicts survival in middle-aged/older individuals
> I used to see an ex-NFL running back in the gym sauna. He could barely move most days before 30+ minutes in the heat.

This. Anecdotally, I know a retired NFL Offensive lineman. He is on a full NFL disability pension at 35 years old because of knee and shoulder injuries. Moving anywhere is very difficult for him.

> Would decades of squats, deadlifts, free weights/kettlebells ... to withstand most chances of hip breaks occurring

If you look at a lot of competitive athletes and bodybuilders, they tend to be pretty broken in their old age. E.g. Ronnie Coleman - former Mr. Olympia - could barely walk after tons of spinal and back surgeries.

Maybe you have the bone density - but if you are immobile with tons of joint and arthritis issues, it probably will not help.

Ouch. Out of curiosity, are those local or federal regulations?
dfsegoat··on Effects of fexofenadine, diphenhydramine, and alcohol on driving performance
Maybe. But I would say for me the benefits of not suffering "breakthrough" hayfever attacks far outweigh the side effects.

Antihistamines are great - but the nasal corticosteroids are what really control my hayfever (1) when used consistently.

1 - Hayfever so bad that I used to have to get custom serum shots containing the local pollen profile, every 2 weeks as a kid. Had anaphylaxis twice.

dfsegoat··on U.S. Air Force Creates Completely New Drone for Ukraine, in 2 Months
You don't need a gun when you can create a shotgun like effect covering 15-20m.

E.g. a Russian loitering drone has 2kg of steel ball bearings and plastic explosives combined together. [1]

dfsegoat··on I'm a scam prevention expert and I got scammed
I know it doesn't matter for reading text, but the look is no bueno.

I really think this detracts from the credibility of a "Security expert".

dfsegoat··on Okta’s Investigation of the January 2022 Compromise
> "I am greatly disappointed by the long period of time that transpired between our notification...once WE received the Sitel summary report WE should have moved more swiftly to understand its implications."

This is an example of total non-ownership. He is the CSO. It should be "I" or "My" and not diffusing responsibility onto his team with "We".

In my book you should celebrate your successes as a team ("we", "our") but failures are ALWAYS on leaders ("I", "my").

I switched to a 34" UW UHD display, from 2x 24" - I definitely prefer it.
dfsegoat··on Acute aerobic exercise to recover from mental exhaustion
> I'm curious to learn from your experience if you are able to grow from a "weak-minded" people to a "strong-will" one, however painfully.

Train brazilian jiu jitsu, or another martial art that involves actual physical contact. Mental toughness is a skill that you can develop quickly in endeavors like those.

Generally, pick something that is difficult, or uncomfortable - and do that thing over and over again. It could be as simple a making yourself take 1 minute of cold shower every morning.

dfsegoat··on Silenced AirTags with disabled speakers are popping up for sale online
Genuinely curious:

What are other examples where specific protocols (open or not) are mandated by regulation ?

dfsegoat··on The Geysers – Geothermal Plants Powering Northern California
I live here and a family member managed environment regulatory affairs for companies in the Geysers for about 20 years.

The Geysers power field is a very cool area for a number of reasons. It's dangerous: You can't just walk around in the steam fields. There are risks of poisonous hydrogen sulfide gases everywhere, etc. - but the companies take a lot of care in mitigating these human & environmental risks.

I think one of the coolest things is this:

> However, since October 16, 1997, the Geysers steam field has been recharged by injection of treated sewage effluent, producing approximately 77 megawatts of capacity in 2004

They are literally turning treated human waste into clean energy.

dfsegoat··on The Geysers – Geothermal Plants Powering Northern California
It's a geothermally active area anyway - so seismicity is there to start. But yes, I am pretty sure the consensus is the water injection process causes the seismic activity.
dfsegoat··on Searching for Susy Thunder
Not saying this is the case here, but there is at least a historical precedent from WW2, for the one word reply:

"[McAuliffe] is celebrated for his one-word reply to a German surrender ultimatum: "Nuts!" [1]

dfsegoat··on Doing too much work on one's own before looping in others
No mil. experience myself, but I'd say that while the officers may technically 'manage' the NCO's, that with few exceptions it is the NCO's that actually get things done.
dfsegoat··on Sibyl – Prediction Service at DoorDash (2020)
It's a $12 minimum order where I am anyway. So you pay $12 whether you have $12 of items or not.

So, I am guessing GP has a couple egg-mcmuffins in there somewhere.

dfsegoat··on BioNTech-InstaDeep Early Warning System to Detect High-Risk SARS-CoV-2 Variants
I think most high school (USA) biology courses probably touch on the concept of viruses? This level of detail was certainly taught in high school Advanced Placement (AP) Biology when I took it many years ago.
dfsegoat··on Russia sends troops to Kazakhstan to put down deadly uprising
Anecdote: My martial arts gym hosted a Kazakh olympic wrestler for a few months. He was won of the nicest and friendliest people I have ever met, even though we had a serious language barrier.

Reading this, I will definitely reach out to him.

dfsegoat··on Learn Django Web Framework
A few reasons I like Django in general [Have also used Laravel]:

- Out of the box db modeling + true relational schema generation, migrations & rollbacks. Get going with local sqlite right away.

- You can always check what db migrations are going to do by generating the raw SQL for a migration file. [1]

- It has a separate, secure web admin for data management, user management, + whatever [2].

- Combine with e.g. Django REST Framework [3] for REST API functionality.

- Can run it on AWS Lambda with zappa.(<sigh> "serverless")

dfsegoat··on Artificial Intelligence in the Cockpit
> I find it very surprising that there isn't at least non-AI software to monitor what the pilots are doing.

For a multi-crew aircraft, I believe this is the entire point of Crew resource management [1].

> "Specifically, CRM aims to foster a climate or culture where authority may be respectfully questioned. It recognizes that a discrepancy between what is happening and what should be happening is often the first indicator that an error is occurring"

For commercial aviation, I'd rather take my chances with the crew with 60+ years of combined experience vs. an AI model.

dfsegoat··on Study: Most Dog Breeds Highly Inbred
> What I find interesting is that dogs are way better adapt at living a “city life” or an “apartment life”

This is certainly not the case with some of the herding / working dog breeds (GSD, Malinois etc) - it is borderline cruel keeping them in an apartment in some cases, and dangerous in others.

I lived with a presa canario for a year in an apartment (roommates dog) - it was not a good situation for the dog or anyone else. After I moved out, I learned the dog attacked someone and was euthanized.

Same situation. Most of South Koreas infrastructure / urban centers would be decimated in an 'all out' conflict with North Korea.

dfsegoat··on ‘Rust’ crew describes on-set gun safety issues and misfires days before shooting
These are the 4 most basic tenants of gun safety.

You are expected to know them on any gun range, and most staffed ranges will safety brief / quiz you on them before they let you shoot.

In this case, they say industry SOP would be for 2 people to verify that the weapon is unloaded (set armorer + 1 other).
