Und jetzt alle zusammen einmal nachsprechen, damit wir es uns gut einprägen, weil es immer wieder Leute falsch machen:

*X11 ist nicht das gleiche wie Xorg*

So wie es in dieser Überschrift falsch ist, denn der Support für X11-Anwengungen geht noch lange nicht in Rente, Xwayland sei Dank; es geht nur um den Support zum Betrieb von Gnome mit Hilfe von Xorg[1].

After we're done with containerization of software, let's continue with banks? 🤔

Overheard at the lab: “I don’t understand why people do drugs when they could be doing operating systems research instead.”

New network equipment with a fancy gadget. 🥰

@deneb Well, as long you are aware of the memory foot print, all good.
Have an eye on the nf_conntrack slab (/proc/slabinfo).

@deneb If you don't need port translation, consider static nat using `tc-nat(8)`.

@bmgnrs @phoenix hehe, no worries. :-)

@bmgnrs @phoenix Thx! TBH, I was interested in the particular variant of @phoenix's version. All the subtle differences make it interesting.

@phoenix do you mind sharing the recipe?

I don't know why and how, but it took me years to find this extremely useful trick:

Seriously impressed with Victoria Logs.

We're replacing our ElasticSearch cluster (27 nodes, ~588 CPU Cores, with 4656gb RAM) with a single VL Node (8 CPU Cores, 64gb RAM).

We shipped 100m logs to VL in the last hour - box is basically idling with only a couple of GB of RAM used. Any random search query returns in a fraction of a second.

Seriously seriously impressive.

Sometimes bugs are so funny that you don't know whether to cry or to laugh.
Today: Linux on a Raspberry Pi booted from U-Boot loads an initramfs, even though no initramfs address was explicitly configured in the booti command.

Q: "Why have you suddenly been reworking coredumping, Christian?"
A: "Because I'm a clown and also I had it with all the CVEs because we provide a **** API for userspace."

So now that @torvalds merged the pidfs and initial coredump work things are already better but I have more work there.

In other news, there's two new CVEs in userpace that should be gone completely by installing a pidfd into the umh or by using the coredump socket.
