🛡️ DHCP Snooping: First Line of Defense in L2 Security
Rogue DHCP servers can poison your network, assign fake IPs, and redirect traffic. DHCP Snooping protects against this by:

• Validating DHCP messages via trusted ports
• Building a binding table for IP–MAC–VLAN mappings
• Blocking untrusted responses at the switch level

It’s simple, effective, and essential for campus & enterprise networks.

📘 Learn how it works, where to deploy, and what hardware supports it:

Solved! 🥳

This was a pretty "interesting" bug. Remember when I invented a way to implement #async / #await in #C, for jobs running on a threadpool. Back then I said it only works when completion of the task resumes execution on the *same* pool thread.

Trying to improve overall performance, I found the complex logic to identify the thread job to put on a pool thread a real deal-breaker. Just having one single MPMC queue with a single semaphore for all pool threads to wait on is a lot more efficient. But then, a job continued after an awaited task will resume on a "random" thread.

It theoretically works by making sure to restore the CORRECT context (the original one of the pool thread) every time after executing a job, whether partially (up to the next await) or completely.

Only it didn't, at least here on #FreeBSD, and I finally understood the reason for this was that I was using #TLS (thread-local storage) to find the context to restore.

Well, most architectures store a pointer to the current thread metadata in a register. #POSIX user #context #switching saves and restores registers. I found a source claiming that the #Linux (#glibc) implementation explicitly does NOT include the register holding a thread pointer. Obviously, #FreeBSD's implementation DOES include it. POSIX doesn't have to say anything about that.

In short, avoiding TLS accesses when running with a custom context solved the crash. 🤯

One thing I notice when reading about people's problems #switching to #linuxaudio is that their attempts/workflows often seem quite complex.
To avoid setbacks and frustration, my suggestion would be to start simple and accept limitations in the beginning, get to know the system better, and then aim for more complex setups as your know-how grows.

🐰🌐 "Switch to in 120 Minutes or Less"—because clearly, everyone has two hours to spare for a process that was *so* easy it needed a 1000-word guide. 🚀🌟 Welcome to the future where swapping out a service involves more than a reality TV show. 📺🤣

New Phone Museum coming to the Denver area. Volunteer search for people who want to help maintain old telecom switching equipment.

Thought I need to install #LibreWolf, but somehow it does not turn up on the @elementary #dock
Well, I really don't need to. They ship #GNOME #Web. It's fine, too. At least for many tasks.

Un nuevo reporte en mi aventura . He estado buscando una app de tareas tipo Todoist para remplazar a la que llevo años usando: @things. Cuestiones: que fuera multiplataforma (Mac, iOS y Linux) y software libre.

La cosa está complicada y la propuesta más habitual es @joplinapp, que ya uso para las notas y mezclarlas con las tareas me da toc 😆

De momento estoy usando , que no es software libre pero que cumple bien. Pero sigo buscando.

@vetgaming @linuxmint actually, @fuchsiii does some clever #Wine #Version #Switching to workaround game-specific compatibility issues instead!

Hola a todos. Estoy borrando todo el contenido de empresas americanas, sustituyendo aplicaciones y cancelando suscripciones. Ahora le ha llegado el turno al lector de pdf de Adobe. ¿Podría alguien recomendar alguna alternativa europea? Muchas gracias

Sigo con el a alternativas éticas y hoy le ha tocado el turno a las notas. He de decir que soy un usuario muy intensivo, desde hace tela de años. De hecho, me he sorprendido al saber que tengo más de 2.400 notas en total 😬
Así que en lugar de migrar todas, he decidido empezar a tomarlas en una aplicación diferente y ya veré cuándo y como las voy pasando. De momento, he visto dos aplicaciones interesantes: y . Va ganando Joplin, pero no lo tengo decidido aún.
