More Network Nonsense
More trouble with the home network today. We had a smart electricity meter installed a few days ago. Though without the “smart” part, because they couldn’t get a good enough signal down in our basement. You’d think they’d have considered that possibility in designing them, since that’s the kind of place where a lot of people’s meters are. Anyway, I think it was interfering with our powerline connection.
We have a BT HomeHub as our main router and connection out to the fibre. But the wifi was a bit crap up at the top of house. So about a year back I got a couple of powerline connectors and used them to extend the 5GHz network upstairs, using another router that we had accidentally acquired as the other access point.
It worked fine, until just the other day. The first symptom was that the Sonos app couldn’t connect to the speaker. I did some diagnosis, and everything was just weird. We could mostly connect to the outside world without any trouble, but I couldn’t connect to the HomeHub’s web interface by name. Nor, I think, by IP address. And then in one of my experiments I tried a slightly different IP address (one that shouldn’t have existed on our network), and I found myself at… a Sky box.
Now you know my dislike for that bunch. There’s no way I’d let their networking hardware on my LAN, any more than I’d subscribe to their channels. and in any case, just, what?
I wondered if our network could somehow have got crossed with one of the neighbours’. But it seemed so improbable. The neighbouring network would need to be using the same SSID, at the very least.
As you’d imagine, I started taking components out to try to isolate the problem. With just the BT HomeHub in place, things were back to normal. But as soon as I began adding parts, everything went weird.
Eventually I concluded — guessed, really — that the smart meter might be using powerline itself. We’re supposed to get a screen-based device for monitoring usage, and maybe that communicates with the meter over powerline. And the meter could have an embedded sky router? That seems unlikely, but maybe Sky have the contract to do the phoning home for EDF.
Anyway, since the root of the problem seemed to be at least partly to do with IP address conflicts, I decided to factory-reset everything and rebuild with a different IP address range (I’ve never used 172.16.0.0 before). Along with a new wifi SSID and password.
And so far so good. But I’m having trouble getting the second router to route properly via the first, so upstairs is going to be problematic till I can solve that.
All this is doing, of course, is making me wish that we could get Eeros in the UK. A self-configuring mesh network is exactly what we need, and not all this jerry-rigged nonsense.
Mac Wishing
Those times when you’re typing a document at work on a shonky Windows 7 machine, and longing for your Mac, where you’d have professional text-handling tools, like Marked for previewing Markdown.
Not that you can’t preview, as long as you’ve got a decent text editor such as Sublime Text (well, specifically Sublime). But things are just so much easier with Mac tools.
And I speak as one who has never had the opportunity to use the Mac professionally. I’ve used Windows machines at works since about 1993, and before that green-screen 5250 terminals.
One of these days, though.
Wifi Blues
I didn’t write a post tonight because I spent most of the evening struggling with wifi configuration. And the less said about that, the better.
“Ping” Pong
When the original Unix designers (or, as it turns out, Mike Muuss) chose ping as the name for the command for checking the status of a network host, it was a moment of inspired genius. The word is almost onomatopoeic in its appropriateness.
But nowadays people are pinging each other all over the place: emails, IMs, even phone calls are “pinged” at each other. “I’ll ping you an email,” they say.
The purist in me cringes a little each time I hear it. But it shouldn’t. The word that was so apposite for those early savants is just as suitable today: it communicates a needed concept. And English, of course, is a living, thriving language. So let people get on with it
Just don’t expect me to use it myself.
Civil Disappointment
I’m disappointed about the ruling on different-sex civil partnerships. But at least there’s hope for the future. The judges agreed that things need to be equalised, but they’re giving the government more time to sort it out.
You’ve got to wonder, though, why is the government bothering to fight it? It’s just a waste of public time and money. Who suffers by removing the difference?
Well, on that last, according to the Guardian article:
Jean Rathbone, a celebrant for humanist ceremonies, said opposition to extending civil partnerships came from the “marriage industry and the church.”
The “marriage industry?” I didn’t know there was such a thing. But the term makes sense when you think of the crazy amounts of money people can spend on weddings.
Anyway, onwards. There’s a GoFundMe page to contribute to help keep the campaign going. I’m in.
Maybe
Sometimes you just want to write something. Maybe you have something specific to say, maybe not. Maybe you have nothing to say at all, but just want to get something out there.
Maybe you’ve set yourself a target, and having missed a day (and being aware that you’ll doubtless miss others) you’ve decided you want to keep the average up. So that at the end of 2017 you’ll be able to look back at at least 365 posts in the year.
Maybe at the start of the year, that was about as many posts as were on your blog in its whole history. So it’s a major challenge. But maybe you keep going, even with nothing to say.
Whoops!
OK, I missed a day. Obviously it had to happen sooner or later. But yesterday I just totally forgot.
Oh well. We pick up and keep going.
Brain Explain
Interesting article on psychology wherein Robert Epstein tells us that “Your brain does not process information and it is not a computer.”
It is, as I say, interesting. But it’s also profoundly annoying in the way he asserts that the human brain is not an information processor, but then makes no attempt to explain what it is, instead.
He asserts that the brain does not hold a copy of a song it has learned, for example, but instead “is changed in a way that allows the person to sing it” (I paraphrase).
But isn’t that just another way of saying that it has stored a copy? If that change does not in some sense denote making a copy, then what exactly does it mean? What is the brain doing when the singer recalls the song? Inventing it anew, exactly (or not) as the original composer intended?
I don’t doubt that what he calls “[t]he information processing (IP) metaphor of human intelligence” has its limitations; but he has completely failed to explain them or provide an alternative explanation.
The truth is we don’t understand much about how the brain does what it does; and this guy knows more than most of us. But he’s a psychologist. He no doubt has a deep understanding of the workings of the human mind. But I think if you want someone to explain what we understand of the workings of he human brain, then you want that person to be a neuroscientist.
Right Message, Wrong Messenger
I mean, he’s right, but he’s still fuckin Tony Blair.
