Code Refactor Review

Review code changes the way Sahaj usually asks for review: go deep on reuse, composition, codebase consistency, and anything that reads like slop.

Bluetooth Page Turner for Kindle Paperwhite 6 (12th Gen)

Firmware 5.18.5 · KOReader · AB Shutter 3

Written by Kaj Maney, April 2026 · Major revisions May and August 2026 A working Bluetooth page turner for the PW6 (MT8110 "Bellatrix") platform.

⚠️ Update — April 2026: An upstream fix is in progress that may significantly simplify this setup in future KOReader releases. @zampierilucas (the kindle-hid-passthrough author) has merged a uevent listener for input device hotplug into koreader-base. Once this lands in a KOReader release, UHID keyboards created by kindle-hid-passthrough may be detected natively, potentially allowing direct key-based page turning without the HTTP API workaround. If you're setting this up after the next KOReader release, test native key input first before following this guide. This guide remains valid for KOReader v2026.03 and earlier.

**⚠️ Update — August 2026: the

Why?

If you often connect to your Linux server using VSCode, the "~/.vscode-server/" folder (and sometimes the ~/.cache/ folder too) can get very large because VSCode:

Does NOT clean its download cache after installing extensions;
Does NOT delete old extensions after updating them;
Does NOT remove old VSCode servers after installing a new version.

If your server storage space is limited, you might consider cleaning "~/.vscode-server/" (and ~/.cache/) regularly using the bash script I wrote. Simply run the following command:

curl -sL https://gist.githubusercontent.com/XDflight/5f3509eb84fc282b88059c909036f5bc/raw/fe2a3e7dab19160c17efc7025d138f5350964c0f/clean_vscode-server.sh | bash -s

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k
