Notes may be permanent. My opinions aren't. Founder, Tetrapolar — bitcoin-native settlement for global trade. Secure, non-custodial, discreet.

I still have irrational fear of heights (in open spaces).

I bungee-jumped into a mountain river. I sky-dived. None of that matters.

It appears to me that to truly get rid of irrational fear, you must be exposed to the fear factor on a regular basis.

I’m not going to sky-dive regularly as a hobby though, so I just have to live it it.

Fanaticism is the killer of reason.

For some reason, Orion (@kagi) can’t connect to my #Tailscale devices (via IP or magic DNS) but Yandex Browser works flawlessly.

Can’t help but think government agencies are extremely happy that open-source developers build awesome things for them for free or, at least, through grants that they give out through their pet foundations.

Tailscale vs. Traditional VPNs

Tailscale reimagines VPNs by leveraging WireGuard’s speed and security while adding layers of usability and resilience that set it apart from legacy solutions. Here’s how it stands out:

1. Decentralized Architecture:
Unlike traditional VPNs (e.g., OpenVPN) that funnel traffic through centralized servers (hub-and-spoke), Tailscale creates a peer-to-peer mesh network. This eliminates bottlenecks, reduces latency, and removes single points of failure.

2. Zero-Config Simplicity:
Tailscale automates setup, NAT traversal, and key management. Users log in via SSO (Google, GitHub, etc.), bypassing manual certificate configurations required by protocols like IPsec or OpenVPN.

3. Built for Restrictive Networks:
If direct WireGuard connections are blocked, Tailscale seamlessly routes traffic through encrypted DERP relays over HTTPS, mimicking standard web traffic. Traditional VPNs often fail in such scenarios without complex workarounds.

4. Granular Access Control:
Tailscale adds an ACL layer atop WireGuard, enabling precise user/device permissions. Legacy VPNs typically grant broad network access, increasing security risks.

5. Scalability:
Tailscale’s mesh design scales effortlessly for distributed teams, while hub-and-spoke VPNs struggle with performance drops as user counts grow.

When to Choose Tailscale:

* Remote teams needing low-latency access

* Environments with strict firewalls/NAT

* Organizations prioritizing ease of use without sacrificing security

Traditional VPNs Still Fit:

* Static, on-premises setups with minimal remote users

* Scenarios requiring full control over server infrastructure

In essence, Tailscale modernizes secure networking by combining WireGuard’s efficiency with enterprise-grade management—ideal for today’s dynamic, decentralized workflows.

“I’ll pull you out of the matrix if you buy my course!”

People wanted to spam the bitcoin blockchain with random messages that cannot be deleted, so here’s a protocol that basically does that but without a blockchain.

It’s been over two weeks since I came up with my app idea and I still think it’s awesome.

My idea generator usually works well, but I always have doubts about ideas on the second or third day. This time it’s different, and I haven’t had it happen for a long time.

If I ever launch, I plan to blog about it on Nostr.

Decision:

For a couple of weeks, I will work with a developer from Pakistan whom I found on a classifieds app.

IF works_out

continue

ELSE

hire_dev_company

So, risking a couple hundred bucks and a couple of weeks of time before going with a company that will cost 100x.

Correct. Notes can potentially be rebroadcast to other, free relays and spammers may see them and, say, comment under them using the free relay. But as you’re only subscribed to your paid relay, you won’t see the spam.

If all “proper” users are on paid relays, the spammers will have to also join paid relays and pay for them, which means they have to spend money to join (say, a yearly relays fee for each npub). And because paid relay operators will be quite vigilant with keeping their relays clean, it’ll be cost-prohibitive for spammers to do so.
