First on the list was the Airbender Arrow from Avatar, I was visiting my sister today and because we’re both crazy and weird she shaved it on my head xD

X-Men X-Traordinaire is a general X-Men server with sections dedicated to all X-Men content including the original timeline movies, the alternate timeline movies, and any and all comic runs along with other X-Men media! 

There are specific categories for a whole slew of different interests! We have a category that focus on all different types of Cherik content, a category where you can chatter and share multi-fandom content, there are a bunch of creative spaces (for writers, artists and cosplayers!), along with locked NSFW (18+) channels where you can share all types of explicit content in a safe, moderated area and a whole heap of other lovely channels to chat in!

You can talk about all of your favourite ships in our multi-shipping channels, trade recipes with people around the globe in our food-chat channels, hold writing sprints in our sprinting channel and even connect with others who are currently navigating the new world of work-from-home in our work-buddies channel. 

If any of that sounds intriguing:

so here’s 20 y/o me playing with my Lego:

It’s silly I know but I wanted to do this xDP

Your iptables firewall is already dead.

When a 100Gbps DDoS flood hits your infrastructure, relying on iptables, ufw, or fail2ban is just an exercise in futility.

Here is the hard truth: By the time a packet reaches netfilter, the Linux kernel has already executed context switches and allocated an sk_buff memory structure. If 20 million malicious packets arrive per second, the sheer overhead of allocating and destroying those structures will cause 100% CPU starvation. Your server is dead.

The Fix: The Kernel Bypass Revolution

It’s time to drop packets before the operating system even realizes they exist. We do this using eBPF & XDP (eXpress Data Path). You attach an eBPF program directly to the NIC driver, executing an xdp_drop instruction to discard the packet instantly with virtually zero CPU overhead.

The "Cloud VM" Illusion

Beware of tutorials running XDP on a 1Gbps Cloud VM. They show you beautiful flame graphs of low CPU usage, but it’s a fatal illusion. XDP saves your CPU, but it does not save your bandwidth. If a 40Gbps flood hits your 1Gbps VM, the pipe saturates instantly. Your upstream ISP will panic and issue a Null-Route (Blackhole), completely isolating you from the internet.

Engineering a Real Scrubbing Center

To build a true wire-speed mitigation pipeline, you need:

Raw Bandwidth: 10Gbps to 100Gbps unmetered uplinks on Dedicated Bare Metal to physically absorb the volumetric attack.

BGP FlowSpec: To distribute the attack load across global datacenters.

Per-CPU LRU Maps: Writing production XDP code means handling multi-queue NIC architectures. You must use BPF_MAP_TYPE_LRU_PERCPU_HASH to prevent lock contention, race conditions, and memory exhaustion from spoofed IPs.

Stop paying the massive Cloudflare tax. Deploy raw compute and build your own scrubbing center.
