Citing severe storage constraints, Tsinghua University's TUNA mirror site has removed its Anaconda, OpenWrt, Flutter and GitLab EE mirrors. Existing URLs now redirect to the CERNET joint mirror site or to upstream.
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.
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.
With open source LLMs and the tools the community keeps shipping, AI is finally within everyone's reach. Plenty of people can now run large models on a local laptop — but laptops are underpowered, and they have other work to do; you can't keep a model running on them around the clock. I prefer PVE, so here's my deployment walkthrough, a guide for my future re-deploys.
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.
Sometimes you can't install MariaDB with apt/yum, or you want every node in a database cluster running exactly the same MariaDB version. My motivation this time was building a MariaDB cluster with identical versions across nodes for easier management.
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.
This post shares my personal high-concurrency Nginx configuration on a 2-core 2 GB Ubuntu box. Other Linux systems may differ — take it as reference only.
Recently a new extortion scheme targeting webmasters has emerged from the black/gray industry, and even Baidu is powerless against it — no fix yet. Today I'm exposing how it works from a technical angle.
Fellow webmasters: on November 30, 2023, Baidu's webmaster platform revoked all [Quick Index] and [sitemap] submission privileges. For the record: the revocation has nothing to do with using my [webmaster push tool]. See Baidu Search Resource Platform's December 1, 2023 announcement.
