Meow meow meow

It must have been a very short amount of time. 2 HP is 1,500 watts, probably more light than all lightbulbs in my house combined.

The muon traverses a few hundred meters of detection volume very close to the speed of light, so in the order of one microsecond.

1500 watts is about what an electric kettle uses.

American kettles. Kettles in hard core countries push 2300 to 2400 watts ;-)

American stove startups can do it in 40 seconds with ??? watts by precharging a battery.

Slow-boiled water gives superior flavor!

Keeps the midichlorians from jumping out.

I always cook my water sous-vide

Meh, Lidl sells 3200w kettles.

Where are the three phase models??

Seriously though, a 15A kettle sounds great.


Photonicinduction's 10-second kettle[1] managed about 10kW max (took around 5s to boil water) for a short time, 440V 23A. Then the resistance dropped, it went up to 16kW (426V 33A) and popped. 7-8kW (375V 19A to 400V 20A) seemed more sustainable.

2500W on 240V, single phase AC, 16A, German 'Schuko'-plug is normal. Or was. Some EU-regulation limits that to 2000, or even 1500W only now, for new devices, or something.

Don't care. Still have the old ones, and whatever the electrician wired as '120V 3-phase AC' for the full US-style range in the US.


UK 240V with 13A sockets, 3120W. Sounds like Lidl are rounding up.

Oh boy oh boy I'm excited for the 5G shutdown when the phone I haven't even bought yet will quit working :)

I get the spirit of what you're trying to say (I think) but the truth is that wireless spectrum is an extremely scarce resource. It is bad policy to let inefficient protocols use it without good reason - 2G has the status of "lowest common denominator" and that's probably the only baseline that you should be able to rely on.

There are a ton of other inefficient allocations of spectrum^1, but not all spectrum is suitable for all purposes and the bands for cellular connectivity are highly sought after.

I know you are being sarcastic but 3G antennas in the US were only just recently shut down. 20~ years isn't bad for how rapidly tech advancement has been happening in the recent decades. Obviously AM and FM radio have been continuing for far longer than that but there are legal and logistical reasons for that, at least for now.

Similar to how Apple how moved forward with breaking compatibility for apps with older OS X versions.

Incredibly different scenario, but I think you knew that before leaving a snarky comment... or at least I hope you did.

And wealth inequality means power inequality. It's not really democracy if you can buy elections and buy your way into a government job

That and, bring back the "new tab" custom URL, and, a way to securely host local servers without root but also without just praying that another app doesn't port-squat me

Localhost is an entire /8, so you have a few million possible addresses you can bind to if you want, all on whatever your preferred dev server port is.

Use https://github.com/daisylb/newtab or other extension to load a home page when you open a new tab.

I use an extension for the former and the latter has never been a problem for me using ports > 8000.

+1 for having your own local 'tab home page'!


You can bind to port 0 and have the OS then pick an available port for you.

I don't understand the downvote.

OP said

> a way to securely host local servers without root but also without just praying that another app doesn't port-squat me

Binding to port 0 is a solution. I tested it and I always get a port not used by other programs.


I guess the main disadvantage is you can't reliably link to anything. Maybe not a problem if you only ever need one local server.

Maybe this is an opportunity. Is there already a “DNS for ports” whereby the hosts file is propagated with application process identifiers that are mapped to localhost:port in hosts file?

SRV records do this.

hosts file (the hosts NSS database) does not speak DNS.

however I guess this line of thought comes from that web developers want a number of *.dev.myproject.net domain names to use in URLs and handle by different web listener processes. why don't just run a nginx as reverse proxy for all of your *.dev.myproject.net domains? update your port number ↔ domain name in nginx config; reload is quite cheap.


Careening back to inetd and /etc/services …

It's amazing to me all of the fancy new ways eventually evolve into the thing they were trying not to be in the first place. We see this time and time again. I've been around long enough to have seen it in several situations to the point that at the start of the trend someone looks like the old dog refusing to learn a new trick, then eventually people realize they could have saved a lot of time/effort/money by taking the old's advice and experience.

I have said it before and I am unsure if I stole it: you can recreate nearly any "service" the web/internet has to offer today with only the RFCs prior to April, 1995, with the caveat that I'm technically fine with HTTP; I haven't given it much thought.

I think it was LogStash or Summit Patchy Project, that let you use IRC as a sync for redirecting logs or making a copy. So I made a PCI compliant logging service, immutable ircd (ro fs) that logged to itself via eggdrop locally. All little cattle VMs would have thier logs sourced and synced via logstash to an IRC channel for the vertical the VM "belonged to". All the irc stuff was on an append-only mount on the ircd server, so if audit just snapshot that mount and hand it over.

NOC was in the channels. I think some teams set up dashboard widgets that triggered on irc events.

All that was a POC done completely to prove that it could be done using only stuff from pre-1996 RFCs. I'm sure the company I built it for went with some vendor product instead and I don't blame them, I wouldn't have maintained that - you ever set up ircd? The volume of traffic just for logs was already fun to deal with.

Pedants: I'm working from 15 year old memories and I changed a few details to protect the innocent. I can't remember the project name other than it was a play on "BI" for business intelligence.


In some ways it is an inversion of inetd. Instead of something that listens to a bunch of ports and launches a port corresponding process, the user has a service that will listen to a random port and they wish to address it in a human-readable kind of way.

As far as I know, the hosts file does not afford a port number so a solution would look similar to a proxy on a known port like 443 listening for a particular domain name that hosts routes to localhost and the proxy routes to the service on port whatever. Also need to set up local CA to sign a cert for each of the hostfile domain names. . .

Isn't this "service discovery", which, at least, apple had 23 years ago "bonjour"? I'm not claiming that stuff like bonjour (I'm referring to the apparently infringing "rendezvous") and upnp did what we're discussing; but you could hack em to do it.

I know I generally use fing in a pinch, or nmap, or ask the DHCP server for all the hostnamr<->ip mappings and then nmap -A - t5 (that's threat level five - the system I use)

Is this thing on


That's a good point. I assumed it being a single local server per app.

Support for Unix sockets would be a gamechanger.

I need to trim my fingernails but I am not going to let a crazed axe murderer in my house to do so

Funny enough, I never heard of Quip until now. Looks like Salesforce bought it.

We use it at work and honestly I'd rather have Google Docs. Very limited formatting (why are there only 3 levels of headings?), very slow interface (why does it take what feels like 30s to load a folder with 25 entries in it?) and the search feature might as well not exist. When I write a Quip doc I basically have to realize and rationalize to myself that I am not going to be able to find it again in the future. So much time lost to "anyone else have the link to...". It's a black hole that allows real time collaborative editing and comments. Sometimes they'll have spells of a few hours to weeks where comments or edits are randomly lost. Randomly the UI will also pop up a 500 or 503 error, which never inspires confidence that it is actually saving my edits. I basically do all my writing in markdown locally, then copy it into Quip — both so I have a local copy I can full text search on and so that if it has one of its random fits I don't lose a half day of work.

(You can also very easily get the UI in an inconsistent state. I forget what the exact sequence is for the one I found most recently but it is something like: if you position your cursor after an image, and there is an empty line and then a line with a header, and you press forward delete, it'll get rid of both line and the header. Clicking undo won't get the header back, it'll only reappear when you refresh the page)

Apparently it works on a 30% majority of people
