I was annoyed that the bank my biz uses is increasing prices by 80%, and then I looked at NatWest and see that they charge at least £0.35 to do anything (receiving money, cash, paying something on card, really, the whole lot!) and now I am somewhat less upset

Y'all know what... this #X11 -> #Wayland switch is a great parallel on why we haven't ditched and rewritten #FRRouting yet:

Yes, it's >25 year old code, some of it truly toxic and radioactive, and some really poor design too.

But writing a new one is yrs of pain to get it to 90% (that also need to be funded = 404 here), and then a decade to fix half the edge case hellbugs.

It's written in the blood of previous users&bugs. (h/t @benjojo for that idiom, I had no wording for that concept before)

One for the Brits at the moment

@benjojo HDMI to two cigarettes adapter vibes.

Double ~~barrelled~~ RJ45 QSFP+ module anyone? This monstrosity gets you 2x10G BASE-T in a single QSFP+ port (you are still throwing away 50% of port capacity here though)

It bends around tight spots by the looks of it as well!

Unsure what to think about this, seems like a "well if wg can do it, why can't we"

I mean sure, You can spend all of this time evading advanced memory corruption detection, ASLR, W^X, etc. But have you considered just shoving funny bash strings into every possible hole and seeing if stuff is so busted that it will just run it anyway?

(This compromised a non zero amount of people)

Wow, when did 28TB 3.5" CMR drives show up on the casual market?!

Though looking at ST28000NM000C, the transfer speeds are still not really getting any better. You are still looking at less than 300MiB/s on a 28T spinner...

(You can get 32T SMR from Seagate)

Which needs me to wonder what a "all unnatural ingredients" tea would be like, like how far can science go? What would it even taste like?

Taking a glance at the orange news website's "Whos Hiring" thread and I get the following impressions:

A) Everything is US healthcare tech now?

B) Some YC companies names are so far detached from meaning (What do you think "goblins", "bloop", "Peanut" do?)

C) I see why friends are staying in their semi-grim situation jobs right now

LMAO, does OkCupid run on Excel now???

This just happened recently. I bet this was a botched database migration. Maybe that explains why chat messages are showing out of order too.

It turns out the locking mechanism on one of the uplink ports on a satellite PoP doesn't work, and the RJ45 can move about ~5mm, enough to drop a link when you are fiddling doing something else

Super weird that for the past year+ you just can't transit TCP connections for port 646 (IE: ldp) towards AS6939/Hurricane Electric

Are they patching over some horrible bug in their stack? I mean I don't think anyone is doing multihop LDP, but it's still _weird_ for a carrier to ACL off a TCP/UDP port

Reminds me of the days (maybe still) of Virgin Media dropping all SMB connections at the edge

In the continuing tradition of "everything is AI", Apparently DDoS attacks smarter than a cURL in a while(true){} loop is now AI according to this Nokia slide deck

The idea that botnets are a 2020 thing is a insane assertion to put on a slide deck that is trying to sell people who have DDoS problems mitigation appliances.

There is a conundrum with these kinds of talks, because they are almost always conference sponsor talks. I feel a weird obligation to not call out the insane stuff in their slides, but also. This is such a warped reality being presented. gah.

At some point I do feel a little sorry for the Iridium Satellite Network, it seems to be the punching bag of security research.

On the other hand, it is the most accessible and... vintage/accessible tech

I have a better thermal camera for a few days, one of the infiray sensors that does not have the 9hz ITAR limits!

Little USB-C thing, and only requires a little bit of messing with to give some kind of output in Linux.

sudo rmmod uvcvideo
sudo modprobe uvcvideo quirks=0x02

Is needed, and then the UVC interface "works" (obviously without any of the post processing that is offered by the smart phone apps)

near 30FPS thermal performance is soooo nice, the extra resolution also is welcome

Hmmmm. "cool" feature of some IX's combined with some IX participants.

First, find a IX address that is not in use:

root@linx-ns:~# ping 195.66.231.230
PING 195.66.231.230 (195.66.231.230) 56(84) bytes of data.
^C
--- 195.66.231.230 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

Then hard set it's neighbour mac address to something that is not on the IXP

root@linx-ns:~# ip neigh replace 195.66.231.230 lladdr de:ad:ad:dd:dd:dd dev enp129s0f0.700

Then set a destination route to go via the mac-address-that-does-not-exist

root@linx-ns:~# ip route add 9.9.9.9/32 via 195.66.231.230

and then ping it

root@linx-ns:~# ping 9.9.9.9
PING 9.9.9.9 (9.9.9.9) 56(84) bytes of data.
From 195.66.226.119: icmp_seq=1 Redirect Host(New nexthop: 195.66.225.238)

64 bytes from 9.9.9.9: icmp_seq=1 ttl=63 time=1.47 ms (DUP!)
^C
--- 9.9.9.9 ping statistics ---
1 packets transmitted, 1 received, +2 duplicates, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.720/0.981/1.468/0.344 ms

Cool right??

What is happening here is nuts on many different levels. To start, the non existent MAC address forces this IX (LINX) to treat any packets send to as "BUM" traffic, LINX could have prevented this by using static MAC like quite a lot of the other big ones do.

That however does not explain why we got ping responses... It turns out some routers on the peering LAN don't check if the destination MAC address for a packet is their own before forwarding the traffic! in this case 3 different LINX member routers saw my unknown unicast packet and was like "sure, why not, I'll route that!", and the packet routed all the way through to 9.9.9.9, and a response came back to me.

Mental!
