erva··on Pattern of brain damage is pervasive in Navy SEALs who died by suicide
I think the whole point of the study is exploratory. Looking for commonality in a search of a cause or suite of factors instead of making assumptions.

Maybe it is a physical phenomenon like adrenal fatigue or brain injury, maybe it isnt; that is why people study it.

I'm not sure how much of it you can minimize. You can only control what you can control...and war/combat is chaos. Honestly it seems most things in relation to this over the years has been on treatment, not so much prevention.

Qualifier: Former US special operations operator that served in multiple wars.

My anecdotal take is there are many ways that shock and trauma can accumulate through training and war that are far beyond the minimal effects of an M4.

Firearms: While the primary weapons systems are the M4 and side arm (pistol), there are many weapons systems utilized by special operations such as sniper rifles, crew serve weapons, and niche small arms.

The M82 sniper rifle shoots a 50 BMG round. In either the bolt action or semi-auto versions they feel like you are getting punched in the face when you shoot them.

Crew serve weapons like the MK19 and M2 do pack a punch. The MK19 is a machine gun that shoots 40mm grenades. The M2 is a .50 cal machine gun. These weapons systems are mounted, but the percussion of them is still far greater than an M4.

More niche arms like the M249 SAW, M16 HBAR, full-auto AKs, M240 Golf, MP9, etc are not as mild as the standard M4/M16.

Blasts: There are many types of blasts encountered such as Mortars (inbound and outbound), Flash Bangs, Entry charges, IEDs, Landmines, etc. These do make your head ring if you are close enough to them.

In my own personal experience there are many other daily jarring events that aren't nearly as sexy to talk about. Riding in the back of a 5 ton will almost shake your brain out of your head. Riding in an LCAC (hovercraft) is like riding in a 5 ton. Doing boat work in Zodiacs will bounce you all over the place, especially when doing surf passages. Doing hydrographic surveys right where the surf breaks will pound you for hours and make you a little sick afterwards. When your chute opens on a jump, if jumping round chutes, will make you see stars...the landing is not a soft pretty one like rectangle chutes...you hit the ground hard.

There are many more ways your body gets pounded on a daily basis far in excess of the weapons you use.

erva··on Off-Grid Cyberdeck with RPI and Pelican Case
I am running the Pi from a solid state hdd as I don't trust the sd cards. ATAK/FreeTak does run well on it. Funny you mention LoRa as I am using exactly that. I have a bunch of the TTGO T-beams (915 MHz) that I have paired up with old Android phones that run entirely off the T-beams/Meshtastic. They can be slow at times for messaging, but it really depends on the channel setting (short range vs very long range).
erva··on Off-Grid Cyberdeck with RPI and Pelican Case
I was originally trying to set it up as the Kiwix wifi hotspot. But after playing with that I decided I wanted the pc to have more than one function so I switched to regular Linux with Kiwix.

So now instead of just Kiwix; I also have my handheld radio programming software (CHIRP), ATAK Server, microcontroller dev environment, copy of Collapse OS, etc.

erva··on Off-Grid Cyberdeck with RPI and Pelican Case
I have been tinkering with a cyberdeck for a while now for off-grid usage, so this is a nice find for the hardware side. My main battle lately has been building out the software side; primarily Kiwix (https://www.kiwix.org).
erva··on Americans Are Using Less Steel, Paper, Fertilizer, and Energy
Andrew McAfee did an interview last week w/ Sam Harris [1] that was a fun listen if you are interested in a conversational understanding before reading his book.

erva··on I was just subjected to the most credible phishing attempt I’ve experienced
My wife had the same thing happen to her but luckily our bank clearly says that this is a password reset pin code (don't share with anyone) type of message along with the pin code in the SMS. So, my wife refused to give it to the person on the phone.

A better sms password reset flow would be to first send a text asking "A password reset has been initiated. Was this you? Reply: YES or NO". Then after a YES confirmation they send the reset code along with the same big "Don't share with anyone on the phone" message.

erva··on Spaced Repetition
I have been patiently waiting on the Soffos[1] product from Fountech to be released to give it a try. I am assuming that there is a repetition algo in there as well.

Purposeful mixing or mild randomization of search results also seems like a decent way to help obscure the ranking algorithms to help thwart reverse engineering.

YT now has channel "memberships" built in that mimic Patreon. Since it is integrated into YT you get a streamlined perks platform along with a special icon noting you are a "member" of the channel when commenting.
erva··on China may match or beat America in AI
> academia is a reflection of how wealthy and educated the population is

This is correct, but that doesn't mean causation. Look at any civilization and look at what came first wealth or academia. It seems to me that wealth creates academia.

> That's an "observation" based on racism and nonsense.

Saying something is "racist" does not constitute an argument. I didn't say whether it was "good" or "bad" to have a culture that promotes or suppresses risk taking...no one can. It is not "racist" to say that two things are not exactly the same.

> The things you need to "innovate" are wealth and security. Innovation is a luxury.

Dead wrong. Wealth and security create complacency. "Necessity is the mother of invention" is not just some stupid quip.

>What makes you think they won't?

I don't. My entire post was a postulation, which is why I used phrases such as "it could be", "general observation" and "there may be", etc. It appears that you are merely looking for a fight instead of having a conversation.

erva··on China may match or beat America in AI
I agree. I wasn't using it as de-facto; rather as an idea that may calm the panic of "OMG They have more X than we do!" "They have more X than we do" only works to determine an outcome if all other things are perfectly equal, which they are not. My primary point was the idea that academia does not necessarily mean applied innovation.

That said, how long does it take for a culture to change part of its core structure? Cultures seem to me evolutionary and, aside from rare radical mutations, very slow to change. Then again, with over a 1.3 billion people there are sure to be plenty of sub-cultures with enough size to be a driving force for the whole.

erva··on China may match or beat America in AI
A wordsmith I am not. Thanks for the correction.
erva··on China may match or beat America in AI
Not to sound like an anti-intellectual, but it could be a mistake to assume that innovation comes from academia. Nassim Nicholas Taleb has a convincing chapter (I think it is Chapter 13: Lecturing Birds to Fly) in his book "Antifragile" about this very thing.

Then there are cultural differences that could be at play concerning innovation. It is a general observation that east asian cultures tend to suppress risk-taking and innovation. Whereas, western cultures seem to promote risk-taking and innovation. That is not to say that there aren't risk takers in China and risk averse individuals in the West...just that overall there may be asymmetry. And, very little asymmetry can create very big differences.

So, have all the smartest people you want, doing all the research you want; but if they have no pressure to put that research to practice, nor a desire or support to take the risks associated with implementation then you might as well have nobody doing anything.

Just a thought.

erva··on Bitcoin withdrawal processing suspended
Think about what you just said there. Imagine you are talking about governmental regulatory agencies and banks and re-read the same sentence.
erva··on Chromebox, now for simpler and better meetings
That seems to be the easiest scheme to implement. Most other systems will spin up a unique hyperlink and a require a passcode. By building in something that simple, Google could really have a winner on their hands with this.
erva··on Chromebox, now for simpler and better meetings
> Need to meet with a customer who doesn’t use Chromebox for meetings? That’s easy too—all they need is a Gmail account.

This would be amazing, except no partner or customer our company works with has a gmail account. I have used quite a few different solutions, and while none of them wow me, the one thing all of them did was work for everyone.

For this to become a viable solution for this market it will need to include non-gmail users.

erva··on Bitcoin users smash their iPhones after Apple bans Blockchain from App Store
He meant that you could have sold the iPhone on ebay for $500. You could have then bought a Nexus 5 for $400. You would then have an Nexus 5 and $100. By just smashing the iPhone (as they did here) you just get a Nexus 5.
erva··on Heirloom Chemistry Set
As a resident of Kansas City and having visited John's store many times, I can tell you that this guys is amazing. He does hands on classes for kids (minimum age 7) on chemistry, archaeology, botany, geology, robotics/ electronics, wood working, etc. Just like this kit; he doesn't dumb down anything.

I turn into a kid every time I go into his store.

erva··on 3D Printer for less than $400
You are assuming that "the market" is one homogeneous mass, which it is not.

>Does the market need a cheaper printer, or a better one?

Yes. Some are in the market for a cheaper printer as demonstrated by the popularity of this kickstarter. Some are in the market for a better one. There is plenty of room for both.

erva··on "Attrition is a group statistic. It doesn't apply to me."
As a former Recon Marine I can attest that there are two reasons that people would drop out or be dropped for selection.

The first wave of drops is how you describe. It is people that don't have the basic physical performance to continue. This in my perception accounts for a relatively small number of drops due to everyone going through prior screening.

The second wave of drops is very similar to the first, but the root is different. The failures are typically for physical reasons, but the source was mental. A lay thing to say is "He didn't have the heart." These people are typically labeled as "badge hunters" as they are looking for the bravado of the title, but honestly don't enjoy the job itself. The wrong types of motivation will quickly weed themselves out.

erva··on My New FiberHouse in Kansas City

erva··on My New FiberHouse in Kansas City
The biggest advantage I thought of with fiber access is being able to run initial production servers from you home. This would be a decent way to keep costs down while having the physical server only an arms length away (not really necessary, but makes me feel better anyways).

As a northern Kansas City resident I am patiently waiting for Google fiber expansion to my area (Currently in "Coming Next"). Having an extra bedroom I am excited to make my home available to the Homes for Hackers project as soon as the fiber is available. It will be great to see a startup progress from my couch.
