  • Yeah, fair enough. To my mind I guess I don’t think of array indexes as an example of actual zero based numbering, simply a quirk of how pointers work. I don’t see why one starting from zero has anything to do with the other starting from zero. They’re separate things in my head. Interestingly, the article you linked does mention this argument:

    Referencing memory by an address and an offset is represented directly in computer hardware on virtually all computer architectures, so this design detail in C makes compilation easier, at the cost of some human factors. In this context using “zeroth” as an ordinal is not strictly correct, but a widespread habit in this profession.

    That said, I suppose I still use normal one-based numbering because that’s how I’m used to everything else working.


  • Indexes start from zero because they’re memory offsets, but array[0] is still the first element because it’s an ordinal number, not an offset. It’s literally counting each element of the array. It lines up with the cardinality—you wouldn’t say ['A', 'B', 'C'] has two elements, despite array[2] being the last element.

    When done correctly, the banner is actually a consent banner. It’s a legal thing, not necessarily trying to discourage criminals. It’s informing users that all use will be monitored and it implies their consent to the technology policies of the organization. It’s more for regular users than criminals.

    When it’s just “unauthorized access is prohibited”, though, especially on a single-user server? Not really any point. But since this article was based on compliance guidelines that aren’t all relevant to the homelab, I can see how it got warped into the empty “you no hack” banner.


  • That 10Gb link is almost certainly oversubscribed, though. You don’t actually have 10 Gb of dedicated constant bandwidth, you just have access to 10Gb of potential bandwidth. You’re unlikely to saturate that link very often, so you won’t notice, but it’s shared with other people.

    It’s different from Google or any other company paying for bandwidth that’s being actually used, not just a pre-allocated link like your home internet.


  • Yes, but only if your firewall is set to reject instead of drop. The documentation you linked mentions this; that’s why open ports are listed as open|filtered because any port that’s “open” might actually be being filtered (dropped).

    On a modern firewall, an nmap scan will show every port as open|filtered, regardless of whether it’s open or not.

    Edit: Here’s the relevant bit from the documentation:

    The most curious element of this table may be the open|filtered state. It is a symptom of the biggest challenges with UDP scanning: open ports rarely respond to empty probes. Those ports for which Nmap has a protocol-specific payload are more likely to get a response and be marked open, but for the rest, the target TCP/IP stack simply passes the empty packet up to a listening application, which usually discards it immediately as invalid. If ports in all other states would respond, then open ports could all be deduced by elimination. Unfortunately, firewalls and filtering devices are also known to drop packets without responding. So when Nmap receives no response after several attempts, it cannot determine whether the port is open or filtered. When Nmap was released, filtering devices were rare enough that Nmap could (and did) simply assume that the port was open. The Internet is better guarded now, so Nmap changed in 2004 (version 3.70) to report non-responsive UDP ports as open|filtered instead.




  • The “make a fork” thing is part of the issue, I think. In general there’s this culture in the open source community that if you want a feature, you should implement it yourself and not expect the maintainers to implement it for you. And that’s good advice to some extent, it’s great to encourage more people to volunteer and it’s great to discourage entitlement.

    But on the other hand, this is toxic because not everyone can contribute. Telling non-technical users to “make it yourself” is essentially telling them to fuck off. To use the house metaphor, people don’t usually need to design and renovate their houses on their own, because that’s not their skillset, and it’s unreasonable to expect that anyone who wants a house should become an architect.

    Even among technical users, there are reasons they can’t contribute. Not everyone has time to contribute to FOSS, and that’s especially notable for non-programmers who would have to get comfortable with writing code and contributing in the first place.

    It definitely encrypts the traffic, the problem is that it encrypts the traffic in a recognizable way that DPI can recognize. It’s easy for someone snooping on your traffic to tell that you’re using Wireguard, but because it’s encrypted they can’t tell the content of the message.





  • I do think people get caught up in hating Epic, but the difference is that if any of those developers felt like releasing on another platform, they could. The “exclusivity”, such as it is, is just happenstance. Whereas Epic’s exclusives are largely actual contracts.

    99% of the games on that list are small-time indie games that only release on Steam because that’s where the market share is, and they probably only have the dev capacity to support a single platform. Steam also has a lot of API support for devs. Those games exist on Epic too, but when people complain about Epic they aren’t complaining about those games, they’re complaining about bigger games that are artificial exclusives, timed or otherwise.

    Steam offers the better customer experience, and Epic can’t compete with it, so instead they just buy exclusivity rights to games. It’s arguably anti-consumer, and definitely different from those games that just happen to only be available on one platform or another.



  • I just don’t understand why you want to copy-paste ChatGPT. Surely the parent commenter could access ChatGPT if they wanted, so you’re not bringing a new perspective. If “content” is all that matters, you could generate a thousand different ChatGPT responses and reply to their comment with each one, but that’s not acceptable. Why not?

    People come here for a conversation with other people, and copy-paste ChatGPT responses don’t actually contribute to that. If all they want is information/content, there are better places to find it. They could use ChatGPT, sure, but they could also use Wikipedia or even an economics textbook. It’s up to them. Even if they use ChatGPT, they’d probably prompt it a few times in a few different ways to get the best info for them.

    If you really want to use ChatGPT in your responses, why not add your own voice? When I suggested commentary I don’t mean that you should just prompt ChatGPT into pretending to be a human, I mean that you should add your own perspective. Editorialize. Pull out the good bits.
