In colo, power runs out before rack space.

Size your cabinet for real draw, A/B redundancy, and growth.

https://xt.om/63Sa

Sizing a colocation cabinet means committing to rack space and power before you've finished filling it, whether it's your first cabinet or your fifth. Here's how to size both realistically, and what to check before you sign.

Most BGP route leaks are missing filters, not attacks.

Detect and prevent them with filters, max-prefix, and RPKI.

https://xt.om/rEDY

A BGP route leak can silently reroute a meaningful share of internet traffic through the wrong network for hours before anyone notices. Here's what a route leak actually is, and how operators monitor for one.

Rate limiting can't stop a full uplink.

DDoS scrubbing filters attack traffic upstream, before it hits your server.

https://xt.om/mxhv

Rate limiting can slow down a determined attacker, but it isn't built to handle a genuine volumetric DDoS attack. Here's what DDoS scrubbing actually does differently, and when a server needs it.

BGP was built on trust. RPKI adds proof.

Major networks now drop RPKI-invalid routes, so getting ROAs right matters.

https://xt.om/sxk5

RPKI has gone from a nice-to-have to something more networks expect from their BGP peers. Here's what it actually does, how it works, and why it's becoming a baseline expectation rather than an edge case.

One IP address, many locations.

Anycast lets BGP route users to the nearest node. It powers DNS, CDNs, and DDoS defense.

https://xt.om/FZRT

Anycast lets a single IP address be announced from many locations at once, routing users to the nearest one automatically. Here's how it actually works, where it's used, and what it takes to run it yourself.

Docker or Podman?

Daemon vs daemonless, rootless by design, and ecosystem support. How to pick your container engine.

https://xt.om/NARS

Docker built the container ecosystem, but Podman has become a serious daemonless alternative. Here's how they actually differ, with real commands, and which one fits your setup.

Not every project needs a database server.

SQLite is a full SQL database in one file. When it fits, and when to move on.

https://xt.om/sbfx

SQLite runs as a single file with no server process at all, and it handles far more real-world workloads than people assume. Here's how it works, when it's genuinely enough, and how to migrate later if you outgrow it.

SysV init vs systemd.

Sequential scripts and runlevels versus parallel, dependency-aware startup. What changed and why.

https://xt.om/rjxx

Every Linux system boots with the help of an init system, but the one running on your server today looks nothing like the one from a decade ago. Here's what actually separates traditional SysV init from systemd, and why it matters for how you manage services.

Containers are two kernel features at work.

Namespaces isolate what a process sees. cgroups limit what it uses.

https://xt.om/QJ7x

Linux namespaces and cgroups are the two kernel features that make containers possible, one hides what a process can see, the other limits what it can use. Here's how they actually work under the hood.

Bash, dash, zsh, or fish?

Each Linux shell trades speed, features, and compatibility differently. Here is how to choose.

https://xt.om/CoNQ

Bash isn't the only shell on Linux. Here's a breakdown of the most common shell types, sh, bash, dash, zsh, ksh, csh/tcsh, and fish, what each is actually built for, and how to check or switch which one you're running.
