CW: NSFW text (via Google Webmaster Tools)

Google Webmaster Tools is very insightful, for example: I feel sorry for the person who was searching "just tits xxx" (with a 100 CTR) and ended up on a blog post about internet exchange fabrics letting bad packets into their broadcast domains.

Google webmaster tools showing a "top queries" for the last 7 days, the top one is "Internet exchange point", the bottom one with just 1 impression and 1 click is "just tits xxx"

It's so nice that my old tweets did not die in vain, and continue to live again in my fedi account via some slightly cursed import feature of honk.

It also means I get to occasionally boost/retoot/bonk some 2018 tweet that applicable to [the situation/me] right now

I don't really think that there is a wrong way of using any kind of social media, however there is absolutely a wrong way to use LinkedIn.

Please, for the love of god people, add a real photo of you (ideally recent) as your avatar (that's legible) so there's I can match up a name with who I actually met at a conference/event

I keep coming across these mostly forgotten machines in my personal infra, just now I finally solved the question of "where are all of those IRC bots I have actually running"

Downside, it's one of _those_ machines with a 3.5~ year uptime

Tasks: 79, 64 thr; 1 running
Load average: 0.00 0.06 0.02 
Uptime: 1263 days(!), 10:55:45

Pouring one out for this one, as it's about to reach end of life in the interests of having less machines running to look after

A photo I took all the way back in March that I thought was a dud (It was a bit dark and the "stock" jpeg output of the camera body didn't really inspire), but it cleaned up super well! Love this

Only minimally edited via the raw reprocessing on the camera body, plus then some light watermark (sorry) in case some knob wants to print it on something without credit etc

Interesting to so easily see the quite aggressive radar/jamming near key Russian sites on European Space Agency's Synthetic-Aperture Radar images

(See for yourself over here)

I suppose there is a trade off on "jam/radar on 1-3Ghz and reveal exactly where the radar is" and being blind on those bands, I assume if this is what the boring open access stuff can see, whatever the intel agencies have is a lot more interesting

But interesting regardless!

New blog post!

bgp.tools is now on 120~ different IX LANs, and since IX LANs are not that different from the ethernet switches in your office and home, that means there are going to be some weird and wonderful things that people have enabled or attached to IX LANs

So I've rounded up in a blog post all of the weird stuff I've seen, how dangerous it is, and why I sometimes know when the Brazil military makes a typo on their router CLI!


Some interesting stuff I found on IX LANs

Looks like Leaseweb / AS60781 missed the 2 key when they were writing config for a BGP announcement, and is now originating a0f:1ac0::/29.

The transit carriers rejected this (yay!) but seems like a lot of people who have direct/bi-lat sessions with them accepted it (implying they have zero BGP filtering with them)

Some networks who seem to have accepted this and carried it over to a decent number of other networks:

  • AS4637 Telstra Global
  • AS24961 WIIT AG (fka. myLoc Managed IT AG)
  • AS33891 Core-Backbone GmbH
  • AS8218 Zayo Europe
  • AS58453 China Mobile International
  • AS60068 Datacamp Limited (CDN77 / DataPacket)
  • AS7195 EdgeUno
  • AS50673 Serverius Holding B.V.
  • AS2603 NORDUnet

Have you considered a 300mm lens?

Pros:

~ See things from distances you would not believe
~ Super flexible for most other things
~ Birds
~ Read the model/serial numbers off the radios on cell towers

Cons:

~ Your cute mirrorless is now 1kg heavier

I know that January 19th 2038 is going to be super interesting and all, but did you know that DVB (the TV stuff) wont blow up?

It uses a slightly different timestamp (that is pretty miserable to parse as it turns out), so it can last a whole few more months past the end of the world, DVB will keep ticking along (at least in it's TOT and TDT packets) until May 22nd 2038
