Technically it's an IPv4 router once you enable net.ipv4.ip_forward in step 1, the rest is enabling a whole lot of supplementary services and operations not intrinsic to the definition of a router.

> * dotted zero vs slashed zero (i prefer the slashed zero, but dotted is fine as well)

The most shocking revelation that I took from this game is how many coding fonts think it's acceptable to neither slash nor dot their zeroes.

I can't imagine using one of those fonts that leaves 0 and O nearly indistinguishable.

Might be a good idea in general to throw out a few preventative iterations of "Your code is broken, can you find the mistake?" before you even bother reading its initial output

Windows NTP client uses UDP port 123 as both the destination and source port, rather than letting the OS assign an ephemeral source port.

Many ISPs (e.g. AT&T Fiber) block UDP traffic with source port 123 to mitigate NTP amplification attacks.

Most people won't notice that problem since low-end consumer routers tend to mangle the source port when they perform outbound NAT. The ISP-provided router will generally do this itself until you enable "DMZ+" or "IP Passthrough" or some similarly-named mode, as home networking experts will typically do so they can manage NAT and firewalling on their own devices.

If a Windows laptop can sync and the wired Windows desktops can't, your wi-fi AP might be doing the necessary source port mangling.

If you add a NAT rule to your router to change the source port for NTP traffic, you should get time sync working.

Yep, humans have had a remedy for the problem of ambiguity in language for tens of thousands of years, or there never could have been an agricultural revolution giving birth to civilization in the first place.

Effective collaboration relies on iterating over clarifications until ambiguity is acceptably resolved.

Rather than spending orders of magnitude more effort moving forward with bad assumptions from insufficient communication and starting over from scratch every time you encounter the results of each misunderstanding.

Most AI models still seem deep into the wrong end of that spectrum.

> do anything under the slogan of "protecting the children".

This is far too forgiving a representation, they are surveillance wolves disingenuously wearing the sheeps' wool of protecting children to further their eventual thought-policing goals of "total information awareness."

Doing anything to protect children is difficult to object to. Using the children as their pretense for monitoring dissidents is really the heart of the matter. It's important to differentiate between the two.

I get that this difference could be subtly implicit in that comment, but let's please make it explicit.

> seemingly private identifiers are SSH pubkeys (I always delete the comment trailer), which are sent to every server you SSH to and also published to places like GitHub

I use this in my .ssh/config file:

  Host *
    IdentitiesOnly = yes

... then you'll only send keys that are specified per-host in .ssh/config with 'IdentityFile' or with a command-line argument.
