I love how if you look at the total unique prefixes in the BGP DFZ over 3 months you see these small spikes (less than 30 min) of like 4000~ prefixes, implying that someone accidentally exported their more specifics and obliterated a subset of their transits/peering sessions, causing the roll back.

But the table grows regardless

a graph that shows prefixes going up over time (3 months) there are tiny spikes and they are all annotated with "Oops"

The kind of photo where you inadvertently take a selfie via another creatures eye

A bird / kookaburra sitting on a ledge, the photo has a "lookup upwards at the bird angle", the 2nd photo is a zoom crop of it's eye where you can see in fisheye style two people in the reflection A bird / kookaburra sitting on a ledge, the photo has a "lookup upwards at the bird angle", the 2nd photo is a zoom crop of it's eye where you can see in fisheye style two people in the reflection

You think web page size bloat is bad on some things? oh boy.

Good afternoon to everyone, except bumn.go.id (an Indonesian government website) for having a (at least) 3GB web page because of embedded MP4's with uncompressed audio and video seeming straight from the camera...

This must cost so much for them, like a single page load could cost at least $0.15 in cloud egress fees alone

The firefox dev tools for bumn.gov.id showing (and still downloading) 1.5GB

This is a sad way for something like Packet.net to end, First sold to Equinix metal and then shutdown, then it's customer list (silently?) sold to some other company as a marketing channel.

Email from limestone networks, to a packet.net spesific email address, the first bit of the email says Hi Ben,     Just wanted to follow up and make sure my last note didn’t get buried.  If you’re still evaluating options for any infrastructure affected by the Equinix Metal sunset

Do you find yourself in the position where you just bought a piece of server kit (new or used) and you do not know what the IPMI password is, and you don't have a OS/screen to reset it, or it's set to some static IP that you don't know?

Please enjoy this small (70MB) image you can put on a USB stick and blindly boot the machine into, assuming the USB boots, it will set the IPMI to a known value, and set the network back to "normal" values (no VLAN and DHCP)

Enjoy! (and report back if you find it worked on things not already confirmed in the readme)

I do appreciate the future proofing of gnu coreutils's "free" command having a --pebi (show output (of RAM) in pebibytes), at the current rate I think that might be a little preemptive

# free --pebi
               total        used        free 
Mem:               0           0           0 
Swap:              0           0           0

Suppose you could probably(?) configure a PiB of Swap though...

I swear some systems setup advice on the internet is literally written by intelligence agencies as a psyop

One of these methods for generating a LUKS (full disk encryption) password is not like the other....

Creating, Formatting and Mounting an Encrypted Disk : Create a passphrase for encryption. Choose something with high entropy (i.e., lots of randomness). Here are two options (pick one): the first one is an open ssl command that is actually okay, the second one is a chain of hashing on the current date time to the second, this is very much not okay

I would love to understand what is going on inside IDNIC, The IRR (outside of the APNIC hosted endpoints) hasn't worked for nearly a entire year:

-rw-r--r--    1 0        0          757397 Jan 30  2025 idnic.db.gz

and their RPKI repo has AAAA records, but the v6 addresses don't work. this may seem harmless because things will eventually fall back to the A/IPv4 record, but that doesn't actually happen in NAT64 environments...

I tried emailing them about this and have never got a response (even trying to go via APNIC to see if they had any better contacts). For a NIC for a country with a population that is reasonably comparable to the United States this is an impressive level of abandonment to infrastructure.

Only realised until I wanted to rack something in U34 that I had accidentally last year racked a 4U 120kg+ mega chonker on the piss... So everything in that box is slightly on a slope, but even worse is blocking out a entire unit under it...

There is no way that I am moving that 4U chassis until the day it dies, or I move colo's. It was reasonably traumatic bringing it in...

Urgh

There should be some kind of browser extension where you can see what your friends of bidding on to avoid accidentally stepping on each other's toes (I don't think this counts as price fixing... probably?)
