This single record will suffice as we will be using a reverse proxy to map each of our application. For the reverse proxy solution, we will be using Caddy, particularly xcaddy.

hosts
🔒 Consolidating and extending hosts files from several well-curated sources. Optionally pick extensions for porn, social media, and other categories.
Why use NextDNS when you can use a lightweight, native solution[1]? Sorry if this sounds condescending but I need less services and not more.

keepassxc
KeePassXC is a cross-platform community-driven port of the Windows application “Keepass Password Safe”.
Thanks for your reply. I do want this tech to work, so I keep hoping I'm wrong here. Unfortunately, you haven't convinced me yet.
> some of them may reject Passkeys without certain metadata or attestations. But you will find out quickly on sign up with that key.
I don't think that's applicable to the case I'm talking about. A relying party could change their implementation to ban the client you are using, after you set up the passkey.
The spec compliance at issue is the truth of the "User Verification" boolean when submitting your unlocked private key to the site for authentication. While it's true that your client could lie about this and the RP would not know, the spec authors view this as a violation of the spec, and a valid reason for RPs to ban users using that client. They even maintain a list of clients they feel violate the spec for UV.
The spec authors are very explicit that clients not meeting their standards are at risk of being blocked by relying parties. See:
>> RP's blocking arbitrary AAGUIDs doesn't seem like a thing that's going to happen or that can even make a difference
> It does happen and will continue to happen because of non-spec compliant implementations and authenticators with poor security posture.
https://github.com/keepassxreboot/keepassxc/issues/10406#iss...
The spec authors' comments on these issues make it very clear that they feel RPs may correctly block users for using clients that do not handle user data in the way the spec authors want them to. This isn't come corner case, it is explicitly built into the spec. I consider that to be incompatible with open source. It's my data and my software. It's my choice what software to use and how to handle my data.

Win11Debloat
A simple, easy to use PowerShell script to remove pre-installed apps from Windows, disable telemetry, remove Bing from Windows search as well as perform various other changes to declutter and improve your Windows experience. This script works for both Windows 10 and Windows 11.
Project mention: I Tried Windows Gaming on a Mac and It's Amazing | news.ycombinator.com | 2025-04-26I simply run this Powershell script once on a fresh install of Windows 11 and don't have to deal with any annoyances even after updates.
https://github.com/Raphire/Win11Debloat
I daily drive MacOS, Windows 11 and Linux Mint on different devices and Windows doesn't particularly bother me post de-bloating, and it easily has the most reliable multi monitor / variable DPI support of the three in my experience.

GoAccess
GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser.
I use https://goaccess.io/ to parse the logs and generate a html report.
As mentioned elsewhere in the thread, there is a lot of bot activity there, that using JS might cleanup a bit.
If you are interested, I have a write up of my setup here, with the report generation down at the bottom:

Project mention: Show HN: First major release of Ente Photos – v1.0 | news.ycombinator.com | 2025-03-29
Hi HN,
We started building Ente in 2020 as an end-to-end encrypted[1] alternative to Google Photos.
We've come a long way since then,
- deploying on-device machine learning[2]
- undergoing a cryptography audit[3]
- open sourcing everything[4]
- replicating to 3 clouds[5]
- and shipping a lot of features[6]
We're trying to build a business that can outlive us, so we have a long way to go – this is only v1.0.
HN has been historically kind with feedback[7][8], a lot of which has influenced our culture in engineering, product, and marketing.
If you've any thoughts on what we could do better, please do share.
Thank you!

I tried years ago, I don't think I got it working, ended up using Rhasspy/voice2json instead (TIL: the creator of both is now the Voice Eng Lead for Home Assistant).
Looks like the GitHub is still somewhat active, although their roadmap links to a dead Trello: https://github.com/leon-ai/leon

Project mention: My Windows Computer Just Doesn't Feel Like Mine Anymore | news.ycombinator.com | 2024-06-21
every software that ever updates has options that are subject to change; a user needs to be proactive in knowing whats running. i do agree we shouldnt need a the privacy treadmill, but until we have better consumer laws the treadmill will continue...
as far as powershell scripts; i cant say i am a fan (i do like the potential targeting of offline machines with something like the mentioned website) - but my favorite to date is still: https://github.com/hellzerg/optimizer/
