Simple machines run on instant pulses. We run on chemical reactions that linger.

Think about your phone or computer—they operate on clean electrical signals that turn on and off instantly. Flip a switch, and the current flows. Turn it off, and it stops. No lingering effects, no chemical residue.

But we're not simple machines. We're incredibly complex bio-electrical systems that use calcium and magnesium channels to generate the electricity that moves our muscles and fires our neurons. The difference? Our electrical signals are created by chemical reactions—and chemical reactions take time to fully resolve.

Here's what happens when you get triggered, angry, or face danger:

Your body floods with stress hormones like adrenaline and cortisol. These chemicals don't just flip a switch—they create a cascading biochemical response. Your heart races, muscles tense, and your entire system prepares for action. Even after the immediate threat passes, **these chemicals are still circul

So if you do the Docker setup, obeying the instructions and substituting everything that needs to get substituted, but don't proofread the files in detail and so miss that line 40 of docker-compose.yml doesn't have the variable {{domain}} like in every other location you need to write your domain, but instead just says LEMMY_UI_LEMMY_EXTERNAL_HOST=lemmy.ml and so you fail to change it away from lemmy.ml... then, everything will work, until you type in your admin password for the first time, at which point your browser will send a request to lemmy.ml which includes your admin username, your email address, and the admin password you're trying to set. And, also, of course your IP address wherever you are sitting and setting up the server.

I have no reason at all to think the Lemmy devs have set their server up to log this information when it comes in. nginx will throw it away by default, of course, but it would be easy for them to have it save it instead, if they wanted to. And my

The Stop ICE Raids Alert Network let's you send and receive mobile alerts about nearby ICE activity whenever, and wherever it occurs.

No downloadable app required. StopICE works with technology already built into your phone. Send and receive mobile alerts via text message, or at stopice.net from any mobile device with a tap of a button.

Puerto Rico has far more rescue animals than can be adopted by the local population, and being an island it's much harder to transport them to other rescues with more space or even who already have an adopter lined up for the animal. It's not feasible for volunteers to regularly transport them.

If you are visiting PR, you can sign up to escort a cat or small dog on your return flight. A volunteer meets you at the departure airport with the animal in a carrier, and another meets you at arrival to pick them up. It's a very easy process since PR is a US territory. The rescue pays for any costs associated with bringing the animal as a carry on, and you get an adorable travel buddy.

This is a little guy named Halo that I escorted a few years ago 🥲 I still think about him and am so happy I got to help him to his new life.

A 2023 study at MIT made this discovery, which could be a boon for storing electricity.

The team calculated that a block of nanocarbon-black-doped concrete that is 45 cubic meters (or yards) in size — equivalent to a cube about 3.5 meters across — would have enough capacity to store about 10 kilowatt-hours of energy, which is considered the average daily electricity usage for a household.

3.5 cubic meters of material ought to be enough to make quite a comfy house

There is a tradeoff between the storage capacity of the material and its structural strength, they found. By adding more carbon black, the resulting supercapacitor can store more energy, but the concrete is slightly weaker, and this could be useful for applications where the concrete is not playing a structural role or where the full strength-potential of concrete is not required.

They talk about making roads with the material, but I suspect electrical posts (utility poles) could also be made of this, which would certa

YSK: How to document that you are a US citizen

https://www.usa.gov/prove-us-citizenship

The most common way to show that you are a US citizen is to show a passport. However, only about 50% of US citizens have a passport.

An alternative to a passport is a Certificate of Citizenship.

Certificates of Citizenship and Naturalization show proof that someone is a U.S. citizen. The website https://www.usa.gov/prove-us-citizenship shows how you can get or replace these documents.

Prove your citizenship: born in the U.S. with no birth certificate. If you were born in the U.S. and have no birth certificate, learn how to get documentation to prove you are a U.S. citizen.

Prove your citizenship: born outside the U.S. to a U.S. citizen parent. Prove your U.S. citizenship without a birth certificate if you were born outside the U.S. to a U.S. citizen.

In Firefox and its derivatives, you can add the non-AI version of DuckDuckGo as a search engine by going into Settings > Search > Search Shortcuts > Add and then giving it a name of your choice with https://noai.duckduckgo.com/?q=%25s being put in the "URL with %s in place of search term" part. You have to remove the 25 part from the URL though, that seems to be a Lemmy quirk with posting a link.

I don't know when they made this available, but I'm learning about this now and it's super useful if you hate LLMs and also use a browser that clears cookies on close (such as Mullvad or LibreWolf).

Red meat has a huge carbon footprint because cattle requires a large amount of land and water.

If you don't have a car and rarely eat red meat, you are doing GREAT 🙌🙌 �*

Sure, you can drink tap water instead of plastic water. You can switch to Tea. You can travel by train. You can use Linux instead of Windows AI's crap. Those are great ideas. But, don't drive yourself crazy. If you are only an ordinary citizen, remember that perfect is the enemy of good.

You can even add a search like this to your browser's inbuilt search engines, with a string like this:

• https://searx.oloke.xyz/search?q=filetype%3Apdf+ %s &language=all (or pick another SearXNG instance here)
• https://duckduckgo.com/?q=filetype%3Apdf+ %s &ia=web

The %s is the placeholder string used by both Firefox, Chromium, and many of their derivatives like LibreWolf, ZenBrowser, and Vivaldi. You'll need to remove the spaces around it in the two URLs above (as Lemmy changed all my URLs without spaces to something different).

This is a general warning to most people, always focus on the accuracy rather than the advocacy part.

Don't read or share an article just because it aligns with your world view.

News organizations in general are the "middle man" between you and events happening in the world.

Don't let the middle man shape your view on reality, focus on accuracy and hopefully you will get a balanced world view.

I had the feeling I couldn't poop for some reason for two days, I also had some sickness from being exposed to too much AC (the doctor said), the doctor gave me medicine against the other stuff which works wonderfully. But my stomach hurt a lot so I ordered a 1 liter bottle of prune juice because I heard it helps against constipation.

Once it arrived I drank the whole bottle at once just to be sure, because I heard it's a natural mild laxative and my stomach hurt so much.

And it worked very well, after 2 hours I was running to the toilet and getting rid of whatever was stuck in there. It worked very well, my stomach stopped hurting after one more hour, wonderful!

But I didn't need to drink the whole bottle, I'm stuck on the toilet the whole afternoon now because as soon as I get out, 2 minutes later I need to run back in, so it's just easier to stay on it.

I think like a cup or two might have been enough.

With the recent event the US just pulled, it is a good idea to freshen up or learn what a Proxy War is and is not.

This makes it much easier to set your screen's brightness to a comfortable level at each time of the day, and to save energy.

(For Windows, see the very bottom of this post.)

On Linux, if you currently have no keyboard shortcuts for that available, a good way to create them is via ddcutil. Once you have ddcutil installed, have your displays' properties printed in the command line by typing ddcutil detect.

This should show you a list of parameters for each of the displays you have connected. For a display of your choice, try these commands:

 undefined

    
ddcutil -n <Serial number> setvcp 10 - 5 # reduces brightness by 5 %
ddcutil -n <Serial number> setvcp 10 + 5 # increases brightness by 5 %

ddcutil -n <Serial number> setvcp 12 - 10 # reduces contrast by 10 %
ddcutil -n <Serial number> setvcp 12 + 10 # increases contrast by 10 %

ddcutil -n <Serial number> setvcp 10 0 # sets brightness to minimum
ddcutil -n <Serial number> setvcp 10 100 # sets brightness to maximum

We all know WD-40 works for making things move when they’re seized, but it also works better than anything for getting rid of all traces of adhesive left behind after peeling off stubborn stickers from things you buy.

It works on nearly all surfaces* – even coated paper! (just be sure not to leave it to soak into the paper.)

Instead of peeling slowly for ages with your fingernail or doing that peel-stick-peel-stick thing for half an hour, soak a paper towel in WD-40 and dab it on the offending sticker remains, wait a few minutes, then wipe off. (*if on coated paper, don’t let it soak, just gently rub it.) Clean the item afterwards to remove the oil left behind.

*it’s best to test a small area first if the object is painted or porous, and be careful with items meant to be food safe, because WD-40 is obviously not food safe.

This is something I wish more people knew, because soooo many manufacturers and retailers put stickers in the worst places and with near-permanent adhes

Most people either use google as their search engine, or one of the "privacy friendly ones" (ddg, qwant, brave, startpage, ...), or use self hosted or publicly available metasearch engines, like searxng, or whoogle, etc.

This websites lists out websites which have their own indexes, and which depend on big providers.

Why YSK?

It is good for your privacy to not use a big provider like google, which now prefers to serve you ai generated ssummaries, which are based on a few giant websites, and this is not good for a open web.

I am also a person who almost always uses "(insert query) reddit" to get better results, because I mostly do not want SEO spam, and reddit results used to be human generated content. Now even that is hit and miss. Also, reddit made a deal with google, so for newer results from reddit, you can only get them from google.

Then we have the "privacy friendly ones" which most of the time are wrappers for other bigger indexes, for example ddg famously uses bing, brav
