rpaddock··on TSA expected to phase out shoe removal policy at airport security
I don't know about my feet. They did take away my shoes to be scanned, which took ~15 minutes. Just normal shoes from a shoe store.

I regularly set off the scanner for no apparent reason and get pulled aside to have a Wand run over me, which finds nothing.

On international travel I get frisked every time I have to show my passport.

rpaddock··on TSA expected to phase out shoe removal policy at airport security
At the Pittsburgh airport the guy at the conveyer belt for the luggage scanner told me to leave my shoes on, as he did for the person before me.

When we got to the body scanner the guy there told me to take my shoes off and put them on the luggage belt. Person before me walked right through with their shoes on.

Glad to see this Security Theater end.

rpaddock··on The first non-opoid painkiller
My late wife took her own life because of Chronic Pain. She was told "The pain has become fixed in your perception".

Many years later we found that the actual cause was a Cerebrospinal Fluid (CSF) Leak.

After two failed surgeries to fix it, she had enough and checked herself out.

See our documentary Pain Warriors for the whole saga.

rpaddock··on Cyborg Embryos Offer New Insights into Brain Growth
I'd thought they were going to talk about things like Cortical Labs, which would match that title.

"Introducing the CL1 The world’s first code deployable biological computer. Test how lab-grown neurons process information and learn."

This is something I've been wondering about:

I have zero concerns about LLM based AIs ever becoming conscious, as SiFi and the current popular press pushes.

What about devices like the CL1 that incorporate real living biology?

rpaddock··on Open-source AI platform for ear-based sensing applications
Thank you, from all those with CSF Leaks and intercranial pressure issues, being high or low. Let me know if I can help.
rpaddock··on Open-source AI platform for ear-based sensing applications
I see "Ear Canal Pressure Sensor" is listed on the website.

I know that NASA was doing some research on using the tympanic membrane to measure intercranial pressure. Ask around, please, and find out if anyone has considered that application. We really do need a better way to detect cerebrospinal leak (CSF Leaks). A CSF Leak was a significant contribution to my late wife's death.

rpaddock··on WSJ These Electric Motors Could Help Break the Dependence on China
I thought they might have been talking about QM Power's technology. They are talking about something else.

I don't know anything about QMP claims other than I came across them a couple of days ago.

"Q-Mag is a breakthrough brushless electromagnetic machine with both permanent and electromagnets on the stator with a magnet-free rotor."

Those were on my late wife's bill too.

After she got hit, ultimately leading to her death in time, by an uninsured guy we had to get a lawyer and fight Eire Insurance for three years for them to honor that line on the bill.

rpaddock··on 'Audible enclaves' could enable private listening without headphones
How is this even remotely new?

There have been patents on it since the 90's. A company was trying to commercialize "Silent Sound" back then.

For example:

US6052336 Apparatus and Method Of Broadcasting Audible Sound Using Ultrasonic Sound As A Carrier (Ultrasound) Lowery 1998.

Holosonics has been selling such systems for a while:

rpaddock··on Lithium-sulfur battery retains 80% charge capacity after 25,000 cycles
For 22 years I designed the electronics controls that ran Longwall Coal Mining Machines. I've been in many mines.

The problem with extracting things from tailings is that they are often contaminated with low levels of Thorium. Extracting the other things like Lithium, Sulfur etc, starts to build up the quantity of Thorium. Which sounds good if you want to build a molten salt Thorium reactor; I understand that China and India have prototype to come on line around 2027. Based on designs and experimental units that the US did in the ~1950s.

The tailing problem is that the company is how handling Nuclear Grade Material which causes the Nuclear Regulatory Commission (NRC) to show up at the mine site. No mine wants to deal with this paper work, and health ramifications, headache so the tailings are not used.

If the profit ratio to headaches would improve things might change.

rpaddock··on The hallucinatory thoughts of the dying mind
About eight hours before my father died he was having a conversation with his unseen mother, who died when he was 14.

I asked him "Who are you talking to?" and got a rather rude response, not like him, "My mother" in a tone you give a five year old "go away kid you are bothering me".

The International Association for Near-Death Studies (IANDS) is worth checking out if you have interest. I've never had a NDE, however I've spent a lot of time in their library in Durham North Carolina.

Females have better episodic memory than males. The structure of the brain is physically different. Male brains are wired more front to back and female brains more side-to-side:

rpaddock··on FCC opens entire 6 GHz band to low power device operations
“DNA Breathing Dynamics in the Presence of a Terahertz Field” by B. S. Alexandrov, V. Gelev, A. R. Bishop, A. Usheva, K. O. Rasmussen (Submitted on 28 Oct 2009)

"Abstract: We consider the influence of a terahertz field on the breathing dynamics of double-stranded DNA. We model the spontaneous formation of spatially localized openings of a damped and driven DNA chain, and find that linear instabilities lead to dynamic dimerization, while true local strand separations require a threshold amplitude mechanism. Based on our results we argue that a specific terahertz radiation exposure may significantly affect the natural dynamics of DNA, and thereby influence intricate molecular processes involved in gene expression and DNA replication."

rpaddock··on FCC opens entire 6 GHz band to low power device operations
The book "The Body Electric: Electromagnetism And The Foundation Of Life" by Robert Becker and Gary Selden, is a foundational book for this research. First published in 1998.

Becker in his research found that lower power levels could have biological effects, everything else being equal, than higher power levels.

rpaddock··on Meta Says It Is Cracking Down on Organized Crime Behind Scam Centers
I reported a Scam account to Facebook and their replay was more or less:

"We are too busy to look at your report. We know you are disappointed..."

There also isn't a way to report Scams in Messenger or Chats, at least that I've found. They just look at the profiles which usually have no content in them, so not a violation of TOS, and let the people continue with their scamming.

Many single men have given up on the whole dating scene. WGTOW's see 4B's as win for them.

rpaddock··on An Evaluation of the Remote Viewing Program: Operational Applications (1995) [pdf]
"including those funded under government contracts..."

Anyone interested in Remote Viewing needs a copy of the four volume set The Star Gate Archives, covering 1972 to 1995.

https://www.lfr.org/book-store

That is Ed May's site. Ed was the project manager for many years.

Every year some new politician would show up and question the funding. They knew if they showed the politician how it worked they would go back to DC thinking it was just some trick. So each new politician they taught them the protocol and let the politician do it themselves. They got funding for another year.

rpaddock··on LG TVs Start Showing Ads on Screensavers
"...never ever connect your new TV to the internet. ..."

I needed a small HDMI monitor so bought a small Samsung TV at Big Box Store.

It would not function without an Internet connection, could not get past the first power up screen. I returned it to the store.

rpaddock··on Inside a Ferroelectric RAM Chip
I designed in a Everspin MRAM. Had to take it back out when we learned that the small magnet, to activate a reed switch, near the MRAM would destroy it. It did not just lose a few bits, the device was forever dead. We are talking Refrigerator Magnet level field in close proximity.

Great technology as long as no magnetic fields are close to the device.

rpaddock··on Ask HN: Just how dangerous are lithium-ion batteries?
I have this classic "Bag Check" XKCD cartoon taped to my wall. The TSA actually did respond to this cartoon. Some of the comments in that response may be helpful to you.

Phones and Laptops have started fires in peoples homes and on airplanes. The risks are real. Today we have somewhat better charger designs. The most often failure is using a replacement battery that has fake certifications.

In my Day Job I have to deal with UL1642 that deals with Lithium Batteries, you should look that up. I've had one China based manufacture try to self-certify their products with this comment: "Battery burst into flames but did not ignite Cheesecloth". Thereby proving I could use their product. Sorry, I can't have any flames.

rpaddock··on "We've got big news": reMarkable special event – September 4, 2024 [video]
I hope the news is they've added an Opt-Out for uploading all of the tablets data if you want to download a PDF to it.

As far as I'm concerned their Cloud Sync feature ruined a useful tool. Some people, think accountants, doctors and lawyers, are contracted to not share client data. So can no longer use a reMarkable for taking notes.

rpaddock··on Great smartphones to take photos in all life situations
Why do SmartPhone manufactures focus so much on the camera?

If I want a good camera, I'll buy one.

When I buy a phone, I care about the ability to make phone calls without drop outs, not having calls with no audio etc.

I know some of those are network issues, but first you have to connect to the network.

Thank You.
rpaddock··on Table of US Deaths by a physician or surgeon or by medical treatment
Sadly suicide is not listed as one of the causes of death.

My late wife took her own life because of the pain from failed medical treatments. I'd like to know where that falls in those tables?
