  • I’ve been using delta chat for about a year now and I will say I really do like it compared to signal.

    For one thing, email encryption (yes the fucking bedbug of the internet) is being used here, it’s decentralized, and just recently (on android) they’ve added phone calling functionality… fucking phone calling functionality on email encryption.

    I’ll say signal isn’t any safer (in terms of privacy and security) than WhatsApp, and i had a revelation that all centralized messaging services aren’t any better than WhatsApp even the proclaimed privacy focused ones. I have two reasons for this: 1.) They have the option to flick a switch and monetize their entire platform, that includes selling data to data brokers and other individuals. 2.) Because it is centralized it’s easier for hackers to breach and easier for governments to get user data.

    I’m not saying that signal is monetizing their platform, but compared to their decentralized counterparts, they have the option to do so. Delta chat requires building a new messaging service from the ground up, if they wanted to monetize.

    My only complaint is, since it is on email encryption, I can’t receive SMS messages, so everyone would have to transition to delta chat (atleast if you plan to use a chatmail) to get the same network as before. You can also create an account using your personal email and send messages via email.


  • Dark matter isn’t matter, I know shitty name to call something “matter” that isn’t matter, Dark matter is a force. The most common example where dark matter shows up is in astronomy, where galaxy positions aren’t where we calculated them to be, hence there is some external force that is being applied, that we don’t know and haven’t found a way to take into account. I guess we call it “dark matter” instead of “dark force” is because for a force to be applied there must be some mass. Still i think it’s illogical to assume that dark matter is a matter, because we don’t know what force is exerting on it. For all we know it could be the accumulation of other galaxies applying a force on the observed galaxy that we’re simply not taking into account.





  • I’ve personally started using KDE plasma shell version of fedora, its as close to being windows (in terms of technical functionality) without actually being windows. On top of this you have the fedora community, and in a time where access of information has gone to shit, you can be rest assured that someone will get to your question or you’ll find an answer to a question you may have on fedora.


  • Do not fully know the entire context, but based on what’s given, it seems you enjoy math or majoring in mathematics. I think this isn’t an overreaction on your end, this is asshole behavior.

    To clarify, You have the option to learn math, you chose to learn math. I don’t think that’s greed or entitlement, you had the opportunity to learn math and you took that opportunity. Working comes into play when you are in a dire need to make money, and it seems you’re not in that current situation.

    I was once questioning my self-worth, since I wasn’t working at community college. I remembered in 2023 I was doing arithmetic, and in 2025, exactly 2 years from when I started, I was doing multivariable calculus. Within 2 years I’ve surpassed every low expectation set upon me: people thought I was going to do a trade, I graduated with an associates in mathematics, and I’m now doing a bachelors in electrical engineering because I fucking can.

    This random non has no idea of your back story, don’t let him get into your head and make you doubt your self-worth. If you plan on doing engineering or physics the math that you are learning right the fuck now will be applied. By the time you start working there will be so much fucking money that you won’t have a care going into debt. For fuck sake, I’m a sophomore, I could quit now and make $100,000 a year as an FPGA developer, technically speaking.





  • My god, yes. Just yesterday I stopped using duckduckgo since even that has now become increasingly infuriating with AI. I’m using this search engine with no AI it’s based on database queries and to go to a specific website there is a small tab you can use. I love it because now I get to appreciate and use textbooks (whereas i would have chatGPT’d it) because of how limited the queries are and the limited selection. It’s not like google where it dumps the most relevant information at the top, you have to search for it. Anyways, if you were wondering it’s called marginalia search.

    Came from windows laptop that I got about a year ago, before then I was running unironically chrome os. I liked chrome os for it’s Linux features. So when I did go from my Chromebook to a windows, it wasn’t as fun. I also didn’t like all the spyware on windows, and this was the time when I was removing myself from the internet as if I didn’t exist, So it was inevitable I would switch.

    The only reason why I haven’t switched earlier is because I am a university student (currently in electrical engineering) and I was concerned that I would be given an exotic application that my laptop cannot support on Linux. Then I learned the majority of students have macbooks, so if it doesn’t work for me it doesn’t work for them too. That’s when I made the conscious decision to switch from windows to Linux.

    Currently trying out fedora workstation, it is like the Mac os of Linux operating systems (and that’s a compliment).


  • I’ve been using fedora workstation for about a month now, you really can’t go wrong with it. It’s great for laptop, there are also ways to customize it to work with a desktop. I am running it on amd CPU/GPU, so i don’t know how well it works with nvidia and Intel, I know some distributions do a really poor job managing the drivers. I don’t use CAD, but I have done FPGA design and programming (C/C++) and it works great. Haven’t done much gaming, all I have is minecraft installed, I could imagine you can install steam on there as well. Hope this helps.




  • You seriously can’t go wrong with the lenovo thinkpads on eBay. I Got a thinkpad E14 ryzen 7 (7th gen), 48gb ram, 1tb ssd for $400 on ebay with a small hair crack on the hinge.

    At the end of the day, a laptop is a laptop, and the cost difference between a $2000 brand new laptop and a $400 used laptop there really is no argument/justification to be made to buy a $2000 laptop in less-intensive tasks. Here’s a better instance of your money: find a $400 laptop with semi-good performance (ryzen 3 or intel equivalent) put $1600 to a gaming computer and setup a virtual environment with a radeon or rtx gpu at your fingertips.


  • Idea have been summoned.

    Any type of decay, either that be uranium (U) strontium (Sr) thalium (Th), it is caused by an imbalance of radionuclide’s (protons and neutrons) in the nucleus. This is not to confuse with an imbalance of protons and electrons which changes the charge. Basically the nucleus wants to be balanced (IE: x amount of protons and neutrons). If there’s an imbalance of radionuclide’s in the nucleus, it will emit them as forms of radiation.

    There are three kinds of radiation that can be emitted by a radioactive isotope; alpha, beta, and gamma.

    alpha radiation is the heaviest of the three, containing two protons and two neutrons, it is also the weakest in penetrating power because of how much mass it has. You may have also noticed that alpha radiation takes the form of a helium nucleus from its proton-neutron count, that’s because alpha radiation is a helium nucleus!

    Beta radiation is comprised of two forms beta plus (B+) and beta minus (B-). B+ is a positron and it’s a very uncommon form of radiation. I think carbon-13 is an emitter of B+. B-, on the contrary, is an electron and is far more common/abundant across many radioactive isotopes. Th-204, is, approximately, a B- only emitter. U-238 is also a B- emitter.

    Gamma radiation doesn’t have any mass, and is light making it the most potent of the three.

    Now to answer your questions:

    “What happened to the respective electrons?” I think your confusing the difference of a helium nucleus and a helium atom, the helium nucleus indicates the number of neutrons and protons, it does not include the orbiting electrons of which the atom does includ. Alpha radiation is a helium nucleus not a helium atom

    “Does this mean that each uranium atom, with 92 protons, entirely splits into 46 helium nucleei or does it release some number of helium nucleei leaving another element behind?” I highly recommend looking at the U-238 decay chain wikipedia article, it Illistrates how the decay chain process actually works. To answer your question, U-238 releases a helium nuclei during its decay chain process leaving strontium-xyz (forgot the isotope name).

    “How does the concept of half life play into this?” Half-life states that for a given radioactive isotope how long does it take for that isotope to decay half of it’s initial quantity. I think for uranium-238 it’s 4.5 billion years or 9 billion years to fully deplete itself of any radiation.
