Computer gore!

Some network device between San Francisco and London is sometimes corrupting packets (in a way that the packet checksum survives), causing my collectd metrics packets to show up with broken hostnames (and often internal metric values...) and also causing fun named files to be made on my metrics server...

I also wonder sometimes if the destination is sometimes corrupted and my metrics packet zoops off somewhere else on the internet

(The right hostname is airmail .benjojo .co.uk)

Good news, the Tuscolo CT logs are now "Qualified" (meaning that some of your certs are/will soon be using our CT log!!)

The bad news is that by including our new logs in the well known list of CT logs, some stuff now instantly crashes (seemingly because the array of non "Sunlight" (aka next gen) logs is empty).

Impacted things seem to include:

1. 80% of the food delivery app market in Brazil
2. Lots of banks in India
3. Lowes????
4. Basically any app that uses appmattus/certificatetransparency

Suboptimal.

The email that no small biz owner wants to get 🥲

It's wild to me that some reasonably loud speakers can be just 8 watts, puts a Single Board Computer into perceptive, and also my 2kw kettle

Finally rigging up speakers to the desk has been a huge win all around, apart from I assume the NAS's who I assume are not enjoying loud bassline music

TIL collectd (or RRD maybe) tops out at 1000 days of uptime

Also I should probably do something about this 1000 day+ uptime server

(to be clear, this machine is not involved in my biz, this is just a personal system that doesnt run anything that listens on the network)

The access point for Pub WiFi does LLDP, and seemingly also is requesting I send power... I guess maybe if I point a magnetron at this AP it wont like it, but that would I guess be power over 802.11 WiFi

I would like to congratulate google for creating the most perfect phishing email (clicking the button asks for auth on the most powerful account in the org) while also not using any of the counter measures (BMI etc etc) that they tell other people to use to defend against phishing emails

Now this is a cool new trick that is definitely borderline on the halon razor (is it a fuck up? or is it someone doing something malicious?)

This LLM crawler is supplying two different user-agent headers presumably with the idea to confuse systems that restrict or log user-agent values

On the way to lunch the last couple of days I've noticed a tern has found a new fishing spot on my route.

Came back with a real camera just now to take a break from staring at some kernel code, Pretty happy with the results!

New Blog!

There is lots of RFC1918 space out there, yet most people use the same 10 /24 subnets

I ended up having my OOB LAN collide with someones home network a few weeks ago, and decided to find a new subnet to use that won't collide backed up with actual usage data!

Picking uncontested private IP subnets with usage data

Some misc Antwerp pics, I love the idea that being immortalized as a statue means that you're also the resting stop of many pigeons

Antwerp has a nice park (even though a local said this was the bad park ¯\_(ツ)_/¯)

Got some nice crow pics regardless

Love these escape guy icons at Antwerp train station, very Portal-esque

General PSA: don’t apply for a job at Canonical. Do NOT apply for a job at Canonical. Treat the blatantly artificially enormous number of job openings they post as the mirages of trickster fae. They are unhinged. Mark Shuttleworth is unhinged. They will drag you through the mud, disrespect you and your time, and definitely not give you a job. This article I saw today is like the thirteenth of its kind that I personally have seen https://dustri.org/b/my-experience-with-canonicals-interview-process.html

I'm just not in a good place right now :(

BGP handling bug causes widespread internet routing instability

On May 20th 2025 a BGP message was propagated that triggered some surprising (to many) behaviors with two major BGP implementations that are often used for carrying internet traffic.

In a new blog post, I will dissect what that message was, and my thoughts on how it happened:

https://blog.benjojo.co.uk/post/bgp-attr-40-junos-arista-session-reset-incident

WTF happened here I wonder?

Why did a considerable amount of people see a random /17 from Yahoo in their google results for a few days

Fancy mandarin duck

This "We simulated what it would be like if LLMs ran a vending machine biz" paper ends up with the same kind of insane emails that I sometimes get in my inbox, maybe they have emulated the true mind of the average vending machine operator after all

Found some Bees! Love the difference between the 300mm on the camera body I like, vs the 300mm on the body I was pretty meh on

Also, all of these pics are miracles, amazed the bees could hold on in the wind, for getting photos of them was a challenge as they were swishing around

Normal internet infra/computer posting will resume soon btw, I'm just having a lot of fun with the new lens on my Fuji and I have good reasons to go to parks at the moment

London paraqeet !

Also enjoy some crows, who are a real pain to take good pictures of because my camera does not like metering on a black bird in bright sunlight

Squirrel pics!

(the 300mm was a great call, lots of good photos without being in the danger zone of animals)

I wish there was a easy way to write a fedi bot that posts all of the slightly deep fried AliExpress marketing copy

TIL there are PCIe Sound cards (such as the one pictured, a ASUS XONAR_AE) that are actually two devices glued together, a PCIe USB card, and a USB Sound card.

I cannot tell if this is incredibly stupid (this is obviously sub-optimal), or incredibly smart (this will not have any driver issues)

Thinking about that time the robot called google "smart reply/compose" was trying to tell other people that it was not a robot

This RIPE Atlas probe is soon going to be old enough to have mailing list arguments with, and boasts a industry leading "one nine" uptime over those years

DZ: Ben being upset at the state of windows

I boot windows 10 in a VM like once every week for basically just microsoft word (for contract review stuff / blog post edits) and excel (Excel still does better in some areas than gdocs)

but holy fuck, the situation just keeps getting worse. I rebooted this time to get:

A) A new splash screen full of crap I don't want like news tickers etc
B) A intro "Welcome to Microsoft 365 with Copilot" that would not go away

How on earth does the rest of the world deal with this, I'm not trying to get on the desktop linux user superiority complex or whatever, but it's such a user hostile environment that is just constantly trying to test my patience with the amount of crap it's going to throw directly into my face every time i'm just trying to use my goddamn computer to do something

Cant believe I even paid for this bloody license

I would like to congratulate AS49450 for having the longest RIPE org-name, causing bgp.tools wanting to display it's name as:

Federal State Budget Institution NATIONAL MEDICAL RESEARCH CENTER FOR OBSTETRICS, GYNECOLOGY AND PERINATOLOGY named after academician V. I. Kulakov of the Ministry of Healthcare of the Russian Federation

(But it gets crushed down to just 56 chars to prevent a CSS explosion)

Rolls right off the tongue right?
