Google kogs the searches and present the suggestions on the base of it, that is the main drawback to use Google search, apart of privacy, the filter bubble effect. Same as someone which always agree with you, even if you are wrong. Same for Bing, and others which log searches, they are not reliable, no valid.

Radiocokkars and Eartags are probably the future of US citizens, but not by aliens. I think more of neuralink, implanted by default on the newborns.

"You are arrested, you have the right to remain silent, as everything you THINK can be used against you", something like this.

It's an imperative need of it to search better alternatives to Lithium, because Lithium is a very dangerous metal (drill a lithium battery and you'll see ☠️) with severe environment, economic and policy impact. Not a solution for sostainable energy, Every investigation for alternatives are welcome.

Proton batteries are emerging as a promising alternative to lithium-ion batteries for energy storage, offering several key advantages. Recent research from UNSW Sydney has demonstrated a breakthrough in proton battery technology using a novel organic material called tetraamino-benzoquinone (TABQ)[^6].

The technology works by storing protons (hydrogen ions) rather than lithium ions, leveraging their unique properties as the smallest and lightest ions of any element[^7]. The UNSW prototype achieved 3,500 charging cycles while performing well even in sub-zero temperatures[^6].

Key benefits of proton batteries include:

  • Fast charging capabilities
  • Zero carbon emissions
  • Lower environmental impact
  • Enhanced safety due to water-based electrolytes
  • Potential lower costs due to abundant materials
  • High energy and power density

The primary challenges currently facing proton battery development include:

  • High production costs for electrode materials
  • Limited voltage range in existing organic electrode materials
  • Technology still in early development stages[^6]

Professor Chuan Zhao from UNSW notes: "The electrolyte in a lithium-ion battery is made of lithium salt, a solvent which is flammable and therefore is a big concern. In our case, we have both electrodes made of organic molecules, and in between we have the water solution, making our prototype battery lightweight, safe and affordable."[^6]

Researchers at the University of Toronto and Korea Advanced Institute of Science and Technology (KAIST) have developed carbon nanolattices with unprecedented strength-to-weight ratios using machine learning optimization[^1]. The team achieved a specific strength of 2.03 MPa m³ kg⁻¹ at densities below 215 kg m⁻³, creating materials as strong as carbon steel but with the density of Styrofoam[^2].

The breakthrough came through multi-objective Bayesian optimization of lattice designs combined with two-photon polymerization 3D printing. This approach improved strength by 118% and Young's modulus by 68% compared to traditional designs[^3]. By reducing strut diameters to 300 nm, the researchers produced high-purity pyrolytic carbon structures containing 94% sp²-bonded carbon[^3].

The team successfully scaled production using multi-focus two-photon polymerization to create millimeter-scale metamaterials containing 18.75 million nanolattice cells[^3]. "If you were to replace components made of titanium on a plane with this material, you would be looking at fuel savings of 80 litres per year for every kilogram of material you replace," said Peter Serles, the study's first author[^4].

Physicists at Washington University in St. Louis created the first-ever "time quasicrystal" - a new phase of matter that breaks conventional time symmetry patterns[^1][^2]. The breakthrough, published in Physical Review X in March 2025, demonstrates how a quantum system can spontaneously organize its motion into complex patterns that repeat in time but lack standard periodicity[^2].

The research team, led by Chong Zu, created their time quasicrystal inside a diamond by:

  • Using nitrogen beams to create spaces for electrons in the diamond structure
  • Applying microwave pulses to initiate rhythmic patterns
  • Achieving hundreds of stable oscillation cycles before breakdown[^3]

Unlike regular time crystals which tick with one rhythm, time quasicrystals produce multiple incommensurate frequencies - similar to playing multiple musical notes simultaneously rather than a single note[^2]. The system demonstrated robust "subharmonic" responses at these multiple frequencies, proving it was a true new phase of matter rather than just an engineered pattern[^1].

The discovery has potential applications in:

  • Quantum computing memory storage
  • High-precision timekeeping
  • Advanced quantum sensors
  • Signal processing[^3]

Every OS nowadays need a good DNS server and better DNScrypt above. An app to control the traffic, like Portmaster or Pi-Hole is also recommended, irrelevant in which OS. Most activity of everyone is online and there is important to protect the privacy, because there is the biggest privacy hole, not in the OS but PEBCAC

I use PC before MS DOS times and I also used several Linux distros in the past, last Kubuntu and Mint, always in dual boot. But I never saw big advantages above a gutted Windows, but problems with a lot of apps which I needed. Currently I'm on a heavy cleaned W11 which works fast, stable and exactly how I want 100%, why because of this I have to change it, installing another OS? There are no practical reasons for it.

That is the point, but Linux, as said above isn't for everyone an option.

Comments in the web:

**Linux faces several key challenges that limit its broader adoption and effectiveness: **

  1. Software Compatibility Major commercial applications like Adobe Creative Suite and industry-standard business software often don't run natively on Linux[^1]. While alternatives exist, they frequently lack feature parity or full compatibility with industry file formats.

  2. Hardware Support Complexity Device drivers and hardware compatibility remain inconsistent. According to ZDNET, even basic tasks like printer setup can require manual configuration[^3]. Multiple competing package formats (deb, rpm, flatpak, snap) create confusion for software installation[^13].

  3. Fragmented Development Focus The Linux ecosystem suffers from too many competing distributions and desktop environments. As MIT researcher Jonathan Birge notes, "It's downright laughable that an OS with single digit market share would further dilute its market share by having two competing desktops"[^21].

  4. Learning Curve Despite improvements in user-friendly distributions like Ubuntu, Linux still requires more technical knowledge than Windows or macOS for many tasks[^1]. The command line remains necessary for certain operations, intimidating new users.

*(With this point I am not in total agreement, Windows with its plug & play and intuitive UI only SEEMS more simple, but to remove the bad habits, bloatware, telemetrias and other crap, are required a more advanced user to get it, entering quickly into Comanche territory. I think that Windows need a more advanced user as modern Linux distros) * 5. Support Structure Unlike commercial operating systems, Linux lacks centralized support. Users must rely on community forums and documentation that can be overwhelming for beginners[^13]. Enterprise-level support often requires expensive consulting contracts.

  1. Market Share Impact With desktop market share around 3%, many software vendors can't justify developing and maintaining Linux versions of their applications[^21]. This creates a negative feedback loop - fewer applications lead to fewer users, which leads to less software development.

Summary: the best OS is allways the one which best fits the individual needs, a perfect OS for everyone don't exist. Every OS has its drawbacks, certainly Windows the most, but at least it's possible to fix.

Yes, dual boot is an option, but for certain things user need to use Windows. But you can make Windows a valid, fast and private OS, not so easy but possible. Telemetries re a minor problem and easy to avoid not needed. My W11 instalation has less than 1 GB and there is nothing working in the background which I don't want. Certainly I don't use any of the default Windows apps, nor the infame powersHell. Only the Defender and security updates.
