  • I understand that this is frustrating but it is arguably the right option. If the correct owner can recover the account without TOTP then the TOTP isn’t really protecting the account.

    Of course there are various ways to authenticate and it can make sense to have authentication to be (username + password + OTP) OR (email verification) but for a lot of people that email verification is a weaker link. It is more secure to only allow the former.

    What I wish is that more sites would document their account recovery procedure. Often times they ask for a phone number for verification or notifications and that silently becomes a backdoor into the account. Even better would be if users can select what authentication combos are supported on a per-account basis (there are a few companies with “lockdown” settings that are a simplified version of this).

    Of course it then becomes important to make it clear to the user “if you ever loose you X your account is forever lost”. It shouldn’t be surprise.


  • Generally speaking it will be fine. SSH will also refuse keys with open permissions so you would notice if it was wide-open to other users of the device.

    But you know if you are running random code or AI harnesses as that user it can be at risk. Or if you copy around the key all over the place it is more likely to leak. But generally speaking you are secure by default, just don’t do something dumb with the key and you’ll have no problems.


  • It sounds pretty reasonable. As long as you keep SSH patched and keep the key safe it should be quite locked down. Do double-check that password login isn’t allowed (or that all users have a very strong password).

    One non-security note is be careful with rsync backup. Generally rsync isn’t considered a backup as any mistakes made in the source will be propagated to the “backup” on next sync. Although there are ways to use rsync to take good backups (like copying to a new directory for each backup).

    I built Chibichange to have a way to conveniently deliver changelogs to Dawarich users

    Have you considered just posting a changelog to your blog? That would be much more convenient than every app I run pinging me in its own way by phoning home to its server.


  • https://xkcd.com/1200/ comes to mind.

    Games have no sandboxing anyways. They can access most of the data on the systems on which they run. Whether the game, crack or a HV crack makes little difference.

    Sure, running a hypervisor or kernel level does allow them a bit more access, mostly around persistence. But I don’t think it is a huge difference to most people.

    So IMHO you are already putting a lot of trust in any pirated software or crack, hypervisor bypasses are really just a small matter of degree. If you don’t trust the crack don’t run it. Easy as that. Or if you want robust protection run games on dedicated hardware with no personal information or in a dedicated untrusted gaming VM.


  • The fact is that it depends and it is a bit confusing for people not familiar. But it isn’t hard to get used to.

    +8Q, Paris isn’t specific enough. There are multiple +8Q inside Paris. It can also be a bit risky to make short codes like this especially with larger cities as different maps may put the city in different spots.

    What does work is +8Q Eiffel Tower which is useful for something like “Meet me here by the Eiffel Tower” or “I’m right here” when you are texting someone you are meeting and you know you are close but can’t see each other.

    So you end up with a few common options:

    • +8Q Eiffel Tower We are pretty close together but need to get the exact spot.
    • V75V+8Q Paris, France For exact spots around a known area.
    • 8FW4V75V+8Q For fully qualified with no reference needed.

    And a few less useful options:

    • 8FW4V7+ This large part of a city.
    • 8FW4+ This part of the country.
    • 8F+ This area of the world.

    If I was designing the system I don’t think I would have done this “trailing zeros assumed” approach. Because IMHO for day-to-day use V75V+ Would be more useful as a shortcut for ????V75V+ rather than the actual V75V????+ showing a rough location on a human scale (in this case the Eiffel Tower park is pretty clearly targeted) rather than an area larger than a city. But that is really the only complaint I have.








  • 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.
