I thought router has to have 6 Ghz band to be called wifi-7, guess I was wrong... -

I have the Pixel 9 Pro XL...Unless this thing is "leaps and bounds" faster than the 9, I'll pass. And by leaps and bounds, I don't mean on benchmarks. "Real world" faster. Most people don't even come close to topping out the performance of their phones. Tensor G5 is Google's most powerful chip to date, boasting a staggering 36 percent performance leap over G4. -

MIT's stunning 'bubble wrap' device squeezes water out from thin air even in deserts by Sayan Sen Image by Matteo Roman via Pexels Massachusetts Institute of Technology (MIT) engineers have built a new kind of device that can pull clean drinking water straight out of the air—no electricity needed. It’s designed for areas where water is scarce and traditional sources like rivers or lakes aren’t reliable. Right now, more than 2.2 billion people globally don’t have access to safe drinking water. In the United States alone, 46 million face water insecurity, with either no running water or water that’s not safe to drink. This new device, called an Atmospheric Water Harvesting Window (AWHW), uses a unique hydrogel panel that looks like black bubble wrap. These dome-shaped bubbles soak up water vapor from the air, especially at night when humidity is higher. During the day, sunlight makes the vapor inside evaporate. That vapor then condenses on a glass surface and drips down through a tube, turning into drinkable water. The AWHW doesn’t rely on power sources like batteries or solar panels. It’s completely passive, meaning it works on its own. The team tested a meter-sized panel in Death Valley, California, one of the driest places in North America, and got between 57.0 and 161.5 milliliters of water per day even with humidity as low as 21 percent. That’s more than what other similar passive devices have managed. “We have built a meter-scale device that we hope to deploy in resource-limited regions, where even a solar cell is not very accessible,” said Xuanhe Zhao, a professor at MIT. “It’s a test of feasibility in scaling up this water harvesting technology. Now people can build it even larger, or make it into parallel panels, to supply drinking water to people and achieve real impact.” Another cool part of the design is how they kept the water safe to drink. Usually, these kinds of hydrogels use salts like lithium chloride to absorb more vapor but that can lead to salt leaking into the water, which isn’t ideal. To solve this, MIT’s team mixed in glycerol, a compound that helps keep salt locked inside the gel. In testing, the lithium ion concentration in the harvested water stayed below 0.06 ppm (parts per million), which is way below the safe limit. The hydrogel domes also give the material more surface area, letting it collect more vapor. The outer glass panel is coated with a special polymer film that helps cool the glass, making it easier for vapor to condense. “This is just a proof-of-concept design, and there are a lot of things we can optimize,” said lead author Chang Liu, now a professor at the National University of Singapore. “For instance, we could have a multipanel design. And we’re working on a next generation of the material to further improve its intrinsic properties.” Published in Nature Water, the study says the AWHW could last at least a year and shows promise for making safe, sustainable water in places with harsh climates. The researchers believe an array of vertical panels could one day supply water to individual households, especially in remote or off-grid locations.

Clear Linux is open source, indeed, so its source code is available for anyone. They're just shutting down its support from them, they're not forbidding anyone else from taking over. -

Linux Mint is also my favorite distro, but I fear what will happen with it if Clem were to disappear tomorrow, to be honest.

Question
firey
Hello, I've got a website that I initially wrote with PHP and jQuery (with jQuery UI, Bootstrap, TouchPunch, etc). I found I was doing a lot of jQuery related work, coupled with some php for initial loads. It became that I was more or less doing double the code (one for php to do the logic at render time, then jQuery adding the same logic for dynamic Ajax related functionality).
I was looking into Angular, and I think that it will allow me to reduce the jQuery code, and remove much of the PHP loading and really keep the PHP on the backend as opposed to front-end. However, I am running into some difficulties (which as I have found out isn't that surprising).
I am starting with my options page as it has multiple pages and the next step with it was to really make it more dynamic/jQuery oriented (perfect spot for angular controllers). However I have a problem and I am not sure how to handle it.
Basically I have a main file called app.js which creates my base application:
This is what is set in the html tag (ng-app="davesapp"). Then I have a second file called: options.js. It defines a second app/module:
This file is included in the options.php page in the content section (so it is loaded only on the options page). This file has all my objects/functions related to the options page. Including loading settings via ajax, ($http.get) and saving settings ($http.post) as well as a function for controlling which options setting to show.
This files controllers only work if I include it in the app.js file. Like so:
Now, this works fine on the options.php page however it causes issues with other pages as I don't include the options.js file on other pages (not needed). Is there some way for me to create an array of some sort that based on the page I can tell it what to include/not include? Like for example on the options page have it look the same as above, but on say the archive page have it be:
Also, I am really liking the Angular idea primarily for things like the ng-repeat and the ng-show/hide that I can put right in the raw html (similar to the way the PHP is done) vs doing foreaches / $('div').show()/hide() of jQuery separately. However I kind of feel like maybe adding in Angular might be over complicating things... but with the level of dynamic stuff that this site will have.. I think it will be much cleaner than trying to do it with both PHP and jQuery alone.
Also, not sure if it will make any difference, but I use the Slim Framework with the site so it handles all the routing/templating. The Angular is purely to make sections of the code much cleaner and allow for more dynamic sections without a bunch of jQuery.
