  • Reverse DNS is different than static IP.

    But yes for outbound email, if you can’t control reverse DNS you will have pain. (Inbound is totally fine) You can in theory just use whatever hostname the ISP’s reverse DNS resolves to however you will get some spam score (or be rejected) as it doesn’t match your “from” domain.

    Outbound email is a huge pain really no matter what. Unless you have a long-term lease on the IP and it isn’t in a bad network you really have to pay someone else if you want reliable delivery.



  • I live in Toronto and was in the Chengdu metro a month ago. I didn’t do a close inspection but it was fine. Honestly probably better than Toronto. The trains had AC and the terminals that I went to were not crumbling.

    I think this meme is pretty reasonable. Toronto had a great start with subways, and still has huge ridership. They also have an excellent bus network. But the funding is very tight and the city has long prioritized inefficient personal vehicles. But it is a good point that you are comparing cities that an order of magnitude apart in population. Toronto also has 2 train lines (one light rail that should be opening within a year, and one subway that is probably 10 years away from opening) which are great to see, finally showing some investment in public transit. But the rate is nowhere near what the political will in China allows and also has a huge focus on new projects rather than keeping maintenance of existing infrastructure.

    In many ways this is a wakeup call. If we wanted this level of infrastructure we could have it. But we need to actually commit rather than continuously slashing budgets so that we can let the rich pay less taxes and continue to subsidize car ownership.








  • I think this is a little confused. Unless your WiFi is open someone seeing your network can’t find out what the WAN IP is.

    And getting your ip can connect the people directly to your box

    “Connect” is a strong word here. Yeah, they can send traffic at it. But that shouldn’t do anything.

    A trace route command to this IP could return intermediate equipment of your isp, helping to pinpoint your town or even your street.

    This is the most reasonable concern. Depending on your ISP and location the IP itself or packet tracing you can get a pretty good idea of the user’s location.




  • IMHO this isn’t really worth it.

    1. x264 is very fast at lower profiles. Especially if you aren’t streaming across the internet often the size hit from the fast profiles is fine. Even if you are streaming over the internet it is probably fine. Getting a slightly faster CPU will also get you super far and is more useful to have lying around than a GPU as it will benefit most things that you do on the server. And worst-worst case a bit of CPU usage isn’t going to hurt much of the things that he is running (except maybe a game server if people are playing at the same time and you are really maxing out all of your cores).
    2. Integrated GPUs are fine for a handful of concurrent streams. Especially the Intel ones which have amazing media engines.
    3. Even if you are going for a dedicated GPU I would go with an Intel ARC. They are way better at media encoding and cost less.
    4. You can always add a GPU later. Wait until you have a need and are seeing problems without.

  • This article really keeps getting better and better.

    • ‘Unparalleled’ snake antivenom made from man bitten 200 times
    • In total, Mr Friede has endured more than 200 bites and more than 700 injections of venom he prepared from some of the world’s deadliest snakes
    • He initially wanted to build up his immunity to protect himself when handling snakes, documenting his exploits on YouTube.
    • he had “completely screwed up” early on when two cobra bites in quick succession left him in a coma
    • I didn’t want to die. I didn’t want to lose a finger. I didn’t want to miss work
    • It just became a lifestyle

  • I still recommend it. I’m not fully happy with the situation but for now I consider it my best option.

    1. I consider Chromium-based browsers out of the question as they give too much power to Google. This is already showing to be a problem with new APIs and “features” that Google is pushing into the web platform and the bigger the market share gets the more control they have.
    2. Web browsers are the biggest attack surface that most people have. Displaying untrusted webpages and running untrusted code is incredibly difficult and vulnerabilities are regularly discovered. I don’t yet know a Firefox fork that I trust enough to reliably respond to security vulnerabilities quickly and correctly.

    So for now I am staying with raw Firefox. Not to mention that as a disto-built Firefox I have some insulation from Mozilla’s ToS. But I am very much considering some of the forks, especially the ones that are very light with patches and are mostly configuration tweaks.
