  • That Linux is a single OS where OS means a distro. They end up thinking that there are 3 systems in the world, Windows, Mac and Linux.

    They’re pretty close, there are three types of kernels used my majority of modern computers but they since they aren’t really into different OS software they equate it with “there only 3 types of OS GUIs”.

    That’s assuming that a human will ever see it. People cracking passwords either have all of them and then use an automated tool or hack a person specifically by decrypinc a password hash which will take an immense amount of time and electricity.

    Still since that’s a concern I can modify the formula. By splitting gmail into g and mail and sticking g at the front.

    I use a password pattern. I have hundreds of different passwords all stored in my head and all between 10-20 characters long. The trick is to have a deterministic formula for picking a password.

    Example: short word + First 6 in url + symbol + short word capitalised + number

    Let’s say the first word is cat and second is dog, symbol is - and number is 5 and you have a Gmail it would give you

    “catgmail-Dog5”

    https://www.passwordmonster.com/ gives it 61 years to crack this one but if you use longer words you get better times.


    • ax^2 + bx + c = 0
    • ax^2 + bx = -c move the c over
    • x^2 + (b/a)x = -c/a divide by a
    • x^2 + (b/a)x +(b/2a)^2 = -c/a + (b/2a)^2 complete the square
    • (x + b/2a)^2 = -c/a + (b/2a)^2 factor the left hand side
    • x + b/2a = sqrt(-c/a + (b/2a)^2) now we just tidy it up
    • x = -b/2a + sqrt(-c/a + b2/4a2)
    • x = -b/2a + (2a/2a) sqrt(-c/a + b2/4a2)
    • x = (-b + (2a)sqrt(-c/a + b2/4a2))/2a
    • x = (-b + sqrt(-4ac + b^2))/2a move 2a into the square root and multiply it with what’s inside

    The derivation of the quadratic formula is nice because it doesn’t rely on anything fancy and it’s all tricks the teacher is likely to teach around the same time you’re learning it. It’s not voodoo shit, it’s just the ax^2 + bx + c = 0 and you solve for x.





  • I bought a used desktop with 4 SATA ports. Has i5 7th gen and currently 5 TB and an 500GB SSD and has max ram of 64GB. I guess the HDD are not included in the price?

    I’m not sure what your software requirements are but if you go the DIY route a desktop works. I made the BIOS auto turn on on power restored and have services start on startup so it gives the server feeling.

    Bonus is that you can use it as a gaming server and upgrade the components easily for a while depending on the motherboard.


  • Snaps sucks, canonical sucks, Amazon integration sucks, KDE updates are years behind which also sucks, pushing snaps over deb sucks, pushing snap over flatpak sucks.

    However, Ubuntu is a great distro. Incredibly stable, very well tested and polished. Installation is super easy and hardware support is very good, unless you got some very new hardware.

    I recommend Ubuntu to a lot of people even though I’d never use it myself. Most people just want their computer to work.
