Windows, OpenSSH, and FIDO2

Being able to use your FIDO2 key (e.g. Yubikey) for OpenSSH is amazing, as long as you're on Linux. For some reason, Windows has very limited out the box functionality if any for this, mainly because the OpenSSH they ship with (C:\Windows\System32\OpenSSH) is very outdated, even on the most up to date Windows 11. Fortunately, Microsoft maintains a more up to date fork of OpenSSH for Windows that can be installed and is very easy to get FIDO2 SSH working.

Using IPv6 with your Custom Domain on Blogger

If you want your custom domain on Blogger, you will most likely just use the typical two CNAME records. This is all easy if you use Google Domains. Instant verification and does all the DNS handling for you no problem. But you might not be using Google Domains and want to redirect your root domain. That doesn't use CNAME because you actually cannot put CNAMEs at the root domain level. This is supposed to be solved by CNAME flattening (sometimes called ANAME or ALIAS records) but you still cannot put IP addresses in either a CNAME or an ALIAS record because these are meant to resolve to IP addresses. Wanting to put an IP address at the root domain using CNAME is called an A/AAAA record.

For Google Domains users, this is dealt with by just checking the box. For non-Google Domains users, Google has documentation on setting this up. But it's missing something: the AAAA records (IPv6). Something even more interesting? Google Domains deals with both A records and AAAA records. Fear not, this is easy to solve.

Making Realtek Audio useful using Realtek-UAD-generic

It's no surprise that Realtek is really bad when it comes to sound drivers on Windows. Ranging from horrible DPC latency issues that people solve by downgrading to extremely old drivers (stop pls), to bugchecks/crashes and just flat-out bad audio. But it is solvable (for the most part).
