I'm doing some well needed scanning and shredding of old letters, and I just came across this 2017 letter from Hargreaves Lansdown claiming that brexit is likely not going to be that bad """ Oh if they could see into the future
Nevertheless, what seems clear to me is that the vote to leave the EU has so far not been anywhere near the economic disaster many predicted

OH HELL NO. This is my name on a version of the Glue pizza/Gasoline spaghetti moment. Other than shitposting about EVPN on fedi and maybe IRC, I've not done anything publicly to do with EVPN. Urghhhh
Thinking back to around that (2017-2020~) time where my primary phone had basically a stock-ish android camera setup. I don't think the phone took very good photos almost all of the time, but there's this weird aesthetic that it sometimes nailed (sort of a dreaming in space kind of feeling) where the HDR would combine to make something quite unique and appealing, while also being a signature to these kinds of cheap phones. I get oddly nostalgic when I see the "overprocessed HDR" aesthetic in other peoples clearly cheap android phone photos, I suppose in the same way that some people adore the ascetic that very cheap/broken film cameras give
"I miss you, too" being suggested by machine just feels like the ultimate "mechanization of conversation" by allowing the outsourcing thought in what are intimate/vulnerable moments. I don't really know how to describe this, but it really does feel quite disheartening I have a Pixel 7, and google appears to have taken the stance that the feature that they put on gmail where they try and guess a appropriate sentence to reply with, should also be taken onto the keyboard on phones. And (IMO) there is some kind of use in this with email, as it turns out that many emails can simply just be responded with "OK"/"yes"/"go for it", and that's basically what the gmail interface excels at (I've never seen it attempt to suggest anything more complex). I've left this feature on my phone for a while a sort of "useless but i'm not going to get out of my way to disable it", until recently where I've got this suggested reply which kind of put a bunch of existential dread in to me. This being a google-ism of course, trying to disable this feature is quite difficult because you not only have to go and disable it on "gboard" but you also have to go and find a page about 5 taps into the settings page to actually stop the UI of the phone itself from trying to suggest the message as a tool tip (see pictured). I would be surprised if many people have. It all just seems... sterile. It's a cliche sure, but it does make me wonder for the future if we hand over moments like this over to word models of the average person replying.
I've lost track of how many "Updates on Lets Encrypt Subscriber Agreement & Ending Expiration Notification" I've gotten already Turns out, I am inconsistent with email addresses!
Talking of ping quirks. If you have a IP address with more than one PTR on it's reverse DNS like so: If you ping it (on seemingly older versions of ping) it will pick a random PTR to display per ping. Resulting in amusing displays like: This was noticed because for some reason, one of Google's net infra IPs has 3 different PTRs, in two different city metros

Oh come on, what a cop out of a danger sign. Tell me where the danger is!
I wonder how often on live DJ gigs is there a talkback style RF channel open with what is going out to the monitors/amps, and how plausible it is to bring a not-bomb-looking phone+SDR setup to dump it during a gig. In unrelated news, I can't wait for a more clean version of whatever this ID to come out
Well, I guess "fuck me" for trying the greener option I guess

My best guess is on a reasonably loaded Intel SP1 system, a SSH connection setup takes 0.007 Joules of power. A random machine I picked out has 15200 SSH connection setups a day A rough estimate on the amount of accessible SSH servers is around 16,280,000 (based on some scanning stuff from 2 years ago) or a constant ish 18.925kw of power. And that is only assuming one party , so likely 2x, so all of the SSH bruteforces going around is costing around 38kW of power. on one hand, not that bad (there are some DCs that can put that into a single rack), on the other hand, that's quite a lot of wasted CPU energy
0.007 * 15200 = 106.4J ~ 0.0000279 kwH
16,280,000 * 0.0000279 kwH = 454.212 kwH (a day)
I wonder what the overall global power consumption is caused by SSH brute force attempts. I guess I need need to figure out how many joules a SSH connection setup costs on a average system ...
Heh, I've reached the bgp.he.net top {N} IX Participation list with the bgp.tools route collector!

Hmmm, did NTT As2914 and Arelion AS1299 depeer in EU? Seemingly everything in the EU between them right now goes via the East Coast USA... (see examples of London-London going via the US, but seemingly this is also happens FRA-FRA) Unsure if this is a maintenance, since surely the whole of the EU would not go at once? Maybe just a misconfig or interesting localpref? Surely that would not happen on both ends though...
You know, some are saying that AI will one day get free will, but they have been overlooking ceph all this time!

closing all my jira tickets as “by design, won’t fix” because the purpose of a system is what it does
The debian java/JRE/JDK situation seems insane. bookworm (stable) is shipping JRE 17, lots of applications require at least 21, Trixie (next stable) is shipping JRE 21, the the current openJDK JRE version is 23 Most of the time if you search for the errors caused by out of date JRE's you get "just install Oracle JDK" with instructions, but as far as I can squint that comes with some licencing payment obligation. All of this feels like putting your head into a alligators mouth! (Do not reply "use nix/arch")
Took apart a DWDM XFP optic left over from the 140km TOSLINK stuff, A lovely person sent a load over that they no longer needed and they were part of my back up plan if more optics didn't work Anyway it seems like they would not have worked anyway because the chip is a The Receiver/Transmitter Optical Sub Assembly (ROSA/TOSA) may be useful for future fun though, Especially since the TOSA seems to have the DWDM Channel written on it, implying that it's statically tuned for that wavelength...

Does anybody know of any academic literature around the medium-term (10 hours a day for 5 days) exposure to smoke machines? The best thing I can find is literature around accumulated exposure around vapes, and this isn't really a fair comparison as people typically don't vape via their noses I'm mostly asking because it turns out that I get a very slow running nosebleed around these things, it's not really an issue but I know other friends where who get much bigger problems (For what it's worth, I realise it's not just a #38c3 smoke machine thing, I've never managed to figure out what causes these very slow nose bleeds until just the last few days, but the last 10 years of these now make sense with this context)
