After 1Password raised prices by 33%, I nearly switched to Bitwarden — but one critical problem made me stay. This post compares the mainstream password managers, analyzes the risks of Passkey lock-in, and shares how to boost security with a YubiKey and successfully negotiate a 25% renewal discount.
Cloudflare Tunnel — familiar to every Cloudflare user. On Linux the binary is called cloudflared, and the open source repo lives at https://github.com/cloudflare/cloudflared. So, with nothing better to do, I registered cloudflared.cn, hooked it up to Cloudflare's services, and then — my account was gone.
In everyday life online, we constantly need to sign up for websites, download resources, or try out services — and most of these platforms ask for an email address. Handing over your real inbox is convenient, but what follows can be endless marketing email or even a potential data leak.
I quit smoking on March 25, 2025. As of this writing I've been smoke-free for 158 days — roughly an 83% success rate (17% chance of relapse). Here I share both my failures and what finally worked.
Microsoft never publicly released a VL edition of Office 2019, so the standard edition has to be converted to VL. I could never remember the steps, so this post is my operating notes for the next reinstall. If you spot a mistake, contact me.
For the past few days my Aliyun CDN has been alerting constantly — traffic and request counts suddenly spike, triggering automatic shutdown. After analyzing the access logs, I found the requests mainly came from IPs in the following areas, all hitting a single image on my CDN.
If you work in IT, you know the 'e-waste scalpers' crowd. I'm one of them — used enterprise hardware is cheap and performs well, and nothing epitomizes it like the Xeon E3/E5 lines: multi-core, multi-thread CPUs for a few dozen yuan, sometimes just a few. But by the law of board-and-CPU pricing, the cheaper the CPU, the pricier the motherboard. So I put together a rough compatibility table of Intel chipset generations, the CPU generations they take, and the DDR memory generations they support, for my future junk-picking reference.
On December 3, 2024, Cloudflare updated its 'Cloudflare Self-Serve Subscription Agreement', explicitly banning IP cherry-picking (deliberately selecting specific Cloudflare edge IPs) and building proxies (circumvention tunnels) on its platform.
Now that Google Chrome has been pushing HTTPS hard, almost every website is served over HTTPS. Have you heard of HSTS (HTTP Strict Transport Security)? It makes your website more secure and faster to load.
The other day someone asked me how I integrate Cloudflare and why it's relatively fast — and why the resolved IPs are still three A records? Let me share my site's architecture and how I use Cloudflare.
