Which operation are you asking about? [1] is a sister comment which I posted that outlines how to do most of the operations I mentioned. [1]: https://news.ycombinator.com/item?id=22168494

The first operations I mentioned (adding or removing a device from a vdev, or adding a new vdev) are one command with no downtime: % zpool attach <pool> <vdev> <device> // add to a vdev % zpool detach &lt

You can grow and add/remove raid1 devices (mirror vdevs) in ZFS without any significant work or downtime. Shrinking does require a bit more work, but depending on your setup it can be done fairly painlessly with send/recv (and shr

The downside of 1-based indexing is that pointer arithmetic stops being consistent with array indexing. Both approaches have downsides.

It's a bit strange that they recommend using the Tor Browser, but the Tor Browser is shown as being "unique" using their fingerprinting setup. Presumably this is just a lack of data rather than a real claim that browsers like

Switzerland (unfortunately) doesn't have what I (as an Australian) would recognise as universal healthcare. It's very similar to the "public option" to use the US terminology. It is still closer to modern healthcare than

On the other hand, it does mean that effective ticket prices would now be more expensive for people who have service animals. While not necessarily malicious, it is a form of discrimination. Airlines don't charge overweight passengers

That's not an entirely accurate understanding of the GPLv3 "anti-tivoisation" restrictions. The restrictions boil down to "if you distribute hardware that has GPLv3 code on it, you must provide the source code (as with G

The problem is that if you want to permit users to do things like dereference pointers and do pointer arithmetic (a requirement for a C-like language) there is no way for the compiler to ensure (even at runtime, because the pointer might no

Oh neat, that's quite cool. I was hoping to write an Android app for magic-wormhole -- so you could share files with mobile devices. Packaging Go on Android is much nicer than Python, so I might revive that idea at some point.

Sure, but you can't communicate with someone using just a client. As I said, it would be like referring to email as "Outlook" or "GMail". To compare Signal and Matrix, you'd be comparing the entire ecosystem (b

If any of the people you are communicating with are using an email provider that they don't personally host, then the problem is exactly the same. In fact, arguably a better comparison to E2EE is that they have to host an email server

magic-wormhole solves this problem (while being encrypted and incredibly easy to use). If the two hosts can directly reach each other, it will directly do the transfer, otherwise it uses a public relay server which both hosts can reach.

The result of the "majority vote" is done preferentially, which means that there is no situation in which vote splitting will occur. It makes no sense to refer to the "majority vote" in this context, because the whole po

The array access example shows why this isn't generally possible -- the programmer hasn't written any bounds-checking code or assertions (they just wrote x[y]). Should the compiler emit bounds-checks? If yes, your code is now slow

When it comes to simplicity, Go is definitely quite similar to C in many respects (and not all of them good). After I started working with Rust for a little bit, I think it better matches the feeling I get with C when it comes to being conf

I'm not sure that is the primary reason -- many other projects have had their compile times explode over many years, even though the same logic should apply. Not to mention if you build the kernel regularly, you benefit from incrementa
