  • ELI5 : Take the string AAAA.

    A simple Cypher would be to change the letters to the next one in the alphabet and offset by 1 for each letter, the message would encrypt to ABCD.

    If you try to compress that, well you can’t do it, otherwise you lose required information.

    If you were to compress AAAA first, you could represent it as the string 4A. You can then encrypt that to 5B.

    Encrypting is about adding entropy to a message. Compressing is about finding common groups and represent them differently so that the size is lower. Compressing an encrypted message is basically useless because you added so much entropy to the message that there are no more recognizable patterns to apply compression to.



  • There are already tools existing for dyndns that are free. If you’re using cloud flare as your dns provider, there’s cloudflareddns that checks your public ip and updates dns records. You just need 1 record to be updated, the other records can just be CNAME to that primary one.

    OVH has DynHost to deal with that as well.

    You could also write a script to do that with your own DNS provider if one doesn’t exist yet. Most have good APIs you can use to that extent. At worse just use cloudflare since it just works and is well supported.


  • I mean, we first need to define what a luxury and what a necessity is. For some things like food, shelter, water, healthcare it’s pretty straightforward. But for resources like energy or communications it’s less obvious.

    I’d argue that the internet is now a necessity rather than a luxury, but many people to this day still don’t have or choose not to have internet access (due to geography or religion). Energy is the same way, if we take an obviously bad example, but say you’re socializing electricity for everyone, what’s to stop someone from mining cryptocurrency on everyone else’s dime ? That person would be profiting off of the social net. Where do we put the cursor between “luxurious” energy use and “necessary” energy use ? It’s a tough thing to figure out.

    Furthermore, for most people you need an incentive to work, right now it’s survival, which is not great, but if all of your needs basic, and more are taken care of by the state, you only work for the luxuries, which would greatly reduce the available workforce. It’s again a tough balance to find.

    Chromium being so prevalent means that it’s a monopoly (internet explorer anyone?) and it can control the web standards, which is something Google already does to some extent.

    They also push their agenda with extensions, manifest v3 being way less powerful for ad blocking extensions. All in all, the more people use Firefox, the less power Google has over web standards, and the more devs are forced to make sure that their site works on Firefox.
