Here's a perspective I see little of in the news: In the globally warmed future the big differentiator will be low carbon cost to manufacture the car and low carbon cost to operate it. So tiny cheap EV's that cover 95% of most pe

I tried repeating every vocal noise my cat made and soon found a noise that obviously meant "no!" After a few years of doing this we built up quite a vocabulary. He had a great sense of humor! It helped a lot that he was very v

I got authorship. The problem is that if I came up with the idea I'd have to be listed as the lead author, and that didn't seem to go over well. If I just contributed to their ideas they were fine with that. It varied per prof,

Would be nice if they had a web app that would cycle through the entire collection randomly. I have an old purchased Windows app somewhere that has several hundred images of the Louvre collection that I used to view that way on a projectio

As an engineer supporting researchers I ran into a peculiar problem. If I suggested an idea they often HAD to ignore it, because they couldn't claim it as their own. Especially the grad students who were trying to get a PhD by coming

Professors cheat also. I've seen several of them invite someone with a reputation to a meeting or just talk with them, then offer to add that person to a paper they are working on "because they contributed to the meeting or conve

I use a dokuwiki for persistently storing ideas, documentation, and notes for everything. I use the vi text editor to always keep open a few files for quick notes every day. I email URL's to myself. I use histories extensively (email

Judging by the fact it's costing me less I'd say it is more efficient than my old oil heating system where I did not have individual room control. The conversion of electricity to heat is extremely efficient, close to 100%. If t

One thing that might motivate lawmakers is if someone starts tracking THEM (with license plate readers, face trackers, camera based heart+breath monitors, Bluetooth/WiFi/Cellular trackers, etc.) and makes the data public. It&#x27

I switched my heating to electric, which I find costs me less than heating with oil since I can lower the heat in individual rooms. My state was powered by nuclear energy and is now powered by hydroelectric. If there were $5000 EV's

I'd like to see an overview of everything that has been hacked so far, arranged by both device/protocol and industry/gov/social structure. It would be interesting to see if there are any categories that have not yet bee

So all the military, government, police, medical, utility, CEO, infrastructure, and other people also have their location data in these databases. How do they all feel about this?

We used git to store and manage data sets for a machine learning project involving chewing detection with audio data used in training. It was cumbersome and the huge datasets caused some problems with git (e.g., searches of our code base g

I've worked in both industry and academia and both can have severe abuse problems. PhD students are used as free labor to advance a prof's reputation so the prof's have no incentive to let them graduate, especially if they p

Where can you buy these in the USA? ATV stores seem to be all ICE. Golf carts are way overpriced and often not enclosed and have little cargo space. The only way I can see to get a small electric utility vehicle that costs under $3000 fo

Possibly they could be interrelated, if say thiamine deficiency made insects more susceptible to pesticides or pesticides also increased thiamine deficiency. The link between pesticides and decreased biodiversity would still exist, but the

Mesh p2p networks do not scale to more than a few hundred nodes sending sparse small messages, unless you can add base stations scattered around that have a more robust power source. However, some people in many areas have generators or ca

I use a Garmin Vivosmart 4 or a Xiaomi Mi Band (v4 or v5) and simply don't connect it to the smartphone. That gets you access to the data on your wrist, but no log of the data. Great privacy with no data collection. If you want data
