Is it political for Apple to forgo investment?
EMCymatics··on Hezbollah pager explosions kill several people in Lebanon
Possibly hydrogen explosion.
EMCymatics··on China is beating the U.S. on high-tech nuclear power by about 15 years
Only cooperation with France and the west has made this possible. There has already been at least one damaging incident that needed a group think to solve.

EMCymatics··on Augmenting biological intelligence with RL in C.elegans using optogenetics [pdf]
They have already done optogenetics on non-human primates.

However, I think those methods of triggering opsins are rather invasive (implants). I don't think it would be hard to design light activated opsins to recieve frequencies in the optical window of skin/bone. If I remember correctly the human body is somewhat resistant genetic transfection, so we have that going for us, which is great.

There is an optical window for skin in the near infrared band.

Bone optical windows are being explored though that has some interference with water.

Better watch what you put in your body /s

Yikes

RIP.

He was a real cool guy.

Offline gaming should never have been destroyed.

Wonder what data they collect from gamers.

They buried the techniques in a few places.

Laser induced breakdown spectrometry (LIBS) https://appliedspectra.com/technology/libs.html

*Enhancing Nuclear Analytical Techniques to Meet the Needs of Forensic Science’ (F11021)*

https://www.iaea.org/projects/crp/d52040

>This project will consider applications based on hand-held and portable devices including (but not limited to) ion mobility spectrometry (IMS), near infra-red (NIR) and X-ray fluorescence (XRF) spectrometers and some bench-top laboratory instruments that have become ‘field’ transportable including laser induced breakdown spectrometry (LIBS), laser ablation molecular isotopic spectrometry (LAMIS), nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS) and multi-spectral imaging (MSI). This CRP is conducted jointly with the Nuclear Sciences Instrumentation Laboratory under CRP G42007.

*‘Field Deployable Analytical Methods to Assess the Authenticity, Safety and Quality of Food (D52040/G42007)*

https://www.iaea.org/projects/crp/f11021

>ion and neutron beam techniques for elemental and molecular analysis is well established and such services are available through a great number of laboratories in the IAEA Member States operating ion beam accelerator or research reactor centers

Isotope spectroscopy I knew of:

For carbon/water isotope determination with spectroscopy you can use cavity ring-down spectroscopy (CRDS) for gas state stable isotopes (water, CO, CO2, CH4). https://en.wikipedia.org/wiki/Cavity_ring-down_spectroscopy https://www.picarro.com/environmental/support/literature/mea...

Picaro instrument is ok at precision, cleaning is not fun, and matrix effects suck. Laser lifetime leaves much to be desired.

EMCymatics··on Facial recognition error message on vending machine sparks concern at university
Worked at a place that put your last four of your ssn for the vending machine. I really hated that.

Yikes. Who knows when I'll remember to look them up again.

I don't see how this move changes anything.
EMCymatics··on Jeff Lawson steps down as CEO of Twilio
Why would that be why George Hu left Twilio?

A CEO has to be the face of the company and needs a good reputation. It seems like he was a good leader.

From an outsider it looks wrong.

EMCymatics··on Duty to Document (2023)
The worst environment is when people don't bother to update documentation. That's when you know you have a garbage shop.

How would you gather evidence of such incidents?
EMCymatics··on Bad scientific code beats code following "best practices" (2014)
>Ultimately I’d say the core issue here is that research is complex and those environments are often resource strapped relative to other environments. As such this idea of “getting shit done” takes priority over everything.

That conforms to my experience

EMCymatics··on Tech Automated the January 6 Investigations
>The FBI was able to identify Coker and gather information about his actions using only location data from his phone and image-recognition technologies. According to the charging document, agents did not even interview him before filing a criminal complaint.
