  • 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.


  • Its a problem but it isn’t a major problem. I am using rspamd without any sort of exotic configuration (basically just enabling things that are provided, not my own rules) and I only get a few spam messages leaking through a week. Maybe slightly worse than GMail but not considerably slow.

    IMHO the only real missing thing out of the box is contacts checking. Which is a huge thing because it is great to have reliable delivery from contacts. But my false-positive ratio is so low anyways that it isn’t a big issue and things like the known_senders module mostly mitigates it.


  • Yes, blocking port 25 outbound is incredibly common by default. Even on some server connections. It is probably better overall for exactly the reasons that you mentioned.

    Or just don’t self-host email

    IMHO this is a bit overblown. Hosting inbound is fairly easy. Mail senders (probably for the worst) are very forgiving even if your TLS cert is expired you will probably get mail. Plus senders are supposed to retry for days if you have downtime.

    However it is unfortunately true that due to spam sending is a huge pain because IPv4 reputation is a huge component. Sure you can get GMail to trust your domain after a month or so of sending if you have decent volume. But other providers who you may mail once a year are just going to go off of IP reputation. However email was basically designed for forwarding and you can use a service like AWS SES to forward your email from a trusted IP pretty easily. If you are low volume (like personal mail) there are tons of services that will do this for free.






  • I’m pretty surprised that all of the audio formats work. I’m not so surprised that the TV has h265, although maybe a bit surprised that it is exposed to the browser. The container support is also pretty surprising. Unless your MKVs are so simple that they are effectively WEBM.

    Or maybe it pops the link out of the browser into a dedicated media player which has decent codec support.

    iDevices do expose h265 in the browser, but the container support is still a bit surprising. But then again WEBM is basically MKV, so maybe that is why it tends to work.


  • There are a handful of common reasons.

    1. The client doesn’t support the formats. Browser clients are notoriously picky not supporting some common video (for example few browsers support h265 and it isn’t generally considered web-safe) and audio formats. But embedded devices may also cause trouble if they don’t have enough CPU to do non-accelerated playback and don’t have hardware support for the codec used.
    2. Playing at a lower bitrate. In that case you can transcode at the fly.
    3. Remuxing. This is things like the moov atom where the actual codecs are supported but not the container or exact packaging of the file.

    But yeah, especially if you are using a player with wide format support you may not need it.




  • 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.

    Actually I would pick GIMP.

    1. Says what it is, an image editor.
    2. No popups and random interruptions.
    3. Not only AI editing examples which makes me thing the tool is AI only.
    4. An overview of the variety of major features it has rather than just AI editing.
    5. Links to helpful documentation rather than endless marketing pages that say nothing.

    Really think only thing I would like to see is some screenshots and examples of using the tool, rather than just info on what it does. But the Photoshop page barely has this, just a few examples of the AI tools.


  • It’s definitely an option. It will do the things that you want (as long as your phone is online, but that is the same for any other solution).

    sending Signal messages with it would be less secure

    Yes, this is because Beeper converts the Signal protocol to the Matrix protocol and vice versa. In order to do this it needs to access the messages. So it needs to decrypt the messages, then re-encrypt them on the other side. This means that the bridge (in this case operated by Beeper) has access to your messages. This is often referred to as “end-to-bridge” encryption, as it isn’t end-to-end anymore.

    This is going to be true of any bridge you use that is hosted by a third party. You are always adding one additional trusted party into your communication.

    the recommended bridge instructions sends me over to Beeper, since I don’t have my own server

    Yes, to practically operate a bridge you need your own Matrix server. This is because the bridge will create a new Matrix user for every remote participant (every phone number you communicate with in this case). Doing this with regular mechanisms would be difficult (as signup is likely restricted in some ways) and inefficient (as each account would need to be checked for new messages separately). Beeper runs their own homeserver so that they can operate their bridges. However Beeper’s bridges are only available to users on the same homeserver (this is not a protocol limitation, just their choice). So in order to use their bridges you need to make an account with them (which you can, it is free IIUC). Beeper also offers custom clients which have special features for interacting with their bridges (for example making it easier to start a conversation with a new phone number).

    The alternative would be to run your own server and bridge (or hire someone to it on your behalf).
