Bank‑Based Anonymous Age Verification (BAV)

A zero‑storage, privacy‑preserving age check that leverages banks’ existing KYC — with the user as the transport layer.

---

TL;DR

• Banks sign an age claim, not an identity. They never learn which site you’re visiting.
• Merchants verify a short‑lived token against their own nonce and a one‑time WebAuthn key. No database required.

Make Ubuntu packages 90% faster by rebuilding them

TL;DR

You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.

Setting

I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is

GKE zonal cluster migration

Apparently a GKE cluster costs $75 a month; this is the most expensive component of the cloud bill for my side project. There is a free tier ... but I recently learned it only applies to zonal clusters, not regional clusters. Much to my chagrin. The pricing docs are very unclear.

So I moved from a regional cluster to a zonal cluster. If you know kube at all you know this is not the kind of thing kube makes easy.

Hard parts about this:

• moving the storage over
• recreating the NEGs

# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

Core Coding Standard

Coding practices are a source of a lot of arguments among programmers. Coding standards, to some degree, help us to put certain questions to bed and resolve stylistic debates. No coding standard makes everyone happy. (And even their existence is sure to make some unhappy.) What follows are the standards we put together on the Core team, which have become the general coding standard for all programming teams on new code development. We’ve tried to balance the need for creating a common, recognizable and readable code base with not unduly burdening the programmer with minor code formatting concerns.
