|
Hello everybody
|
|
and welcome to Hacker Public Radio.
|
|
This is Dave Morris
|
|
and I'm talking to Mr. X. Hi Mr. X, how are you doing?
|
|
Hi Dave, doing fine and doing fine and these interesting things we're loving him.
|
|
Indeed indeed.
|
|
So we're just doing the thing that I think more and more people are doing
|
|
which is just getting together over Mumble Wars or other methods
|
|
just to have a chat, you know, because that's sitting in your house
|
|
without a much chance of talking to anybody is a bit frustrating.
|
|
So it's quite nice to virtually get out and have a wee chat.
|
|
So that's what we're doing.
|
|
Yes indeed indeed.
|
|
Of course, it's also been a video chatting and whatnot
|
|
with other members of the family and whatnot.
|
|
And my mother's becoming very...
|
|
or fear with hangouts and whatnot.
|
|
And my mother's been using duals.
|
|
Which as soon as it seemed to be a bit of a kind of mess
|
|
at Google's done with the video conference and they've got the dual
|
|
which kind of replaced hangouts, but it doesn't do text, chat, you know,
|
|
you can't do text, you want to do video.
|
|
And I didn't even really know anything about duals.
|
|
My brother was telling me he's an IT, so it seems a bit of a mess.
|
|
All right, I don't know anything about it.
|
|
So actually, I was telling you earlier that I had a wee chat
|
|
with a friend using Jitsi during the week.
|
|
We just used the Jitsi Meet thing, which is a web-based thing.
|
|
So you just go to it and start up a chat and it gives you a name.
|
|
I think you can probably give it your own name and then share it
|
|
with your friends or whoever you're speaking to.
|
|
And I think this password is involved or can be, but we didn't bother with that.
|
|
So that seemed to work quite well.
|
|
It does have a text stream as well.
|
|
So you can, when I was having problems with my microphone,
|
|
we were able to say, baby, then can you hear me?
|
|
You know, some stuff over the text, which is quite cool.
|
|
Yeah, yeah, it's a favourable word.
|
|
We just had a wee chat before we hit the record button.
|
|
And I did have a weeb cam many years ago and I gave it to my mother
|
|
and I thought, did you ever use it?
|
|
So next time I see her from a distance,
|
|
it's a socially acceptable distance.
|
|
I'll ask her if she can place it somewhere between us
|
|
and I can pick it up.
|
|
Yeah, that'd be quite good.
|
|
I should say, by the way, just as a digression,
|
|
I'm sitting in my back room with my house,
|
|
but sort of back kitchen, dining room,
|
|
with the back door open,
|
|
because it's really nice weather.
|
|
And my name's Kate's right.
|
|
I'm passionate about it.
|
|
So you will hear noises off,
|
|
but it's all part of the ambience, I think.
|
|
Yeah, I'm sitting in the spare room,
|
|
hobby room, stroke video room,
|
|
and it's cooking.
|
|
So yeah, I'm sure it'll manage.
|
|
Yeah, yeah, yeah, it's just,
|
|
I forget sometimes,
|
|
because I've done recordings like this in the past,
|
|
and then I'm listening to them and they think,
|
|
oh, it's bird song on it.
|
|
You know, there's this,
|
|
some twittering bird outside in the back garden
|
|
or a crow or something shouting.
|
|
And you think, oh,
|
|
what the hell that comes across to people at the end?
|
|
Yeah, well, I actually had that.
|
|
I think I had another diada.
|
|
I was down in the garden at the back of the garden.
|
|
It's not, I think it was garden.
|
|
And I had a tablet with me,
|
|
and I gave my mother a call,
|
|
and it was really weird,
|
|
because I had to turn the brightness
|
|
fairly high up on the screen, obviously.
|
|
But, you know, it was fine.
|
|
And of course, she could see all the greenery in the garden
|
|
and whatnot.
|
|
And I was surprised, you know,
|
|
the life I signal held up really nice.
|
|
And we found our internet connection has been good
|
|
and solid so far,
|
|
so of course,
|
|
all these people online,
|
|
it might be an issue,
|
|
but we've been doing all right, you know?
|
|
Yeah, I can't complain either.
|
|
It's been pretty good.
|
|
I'm actually on an internet connection,
|
|
because I've got a lot of wiring in my house,
|
|
so I like to use that over the wire,
|
|
rather than the Wi-Fi for a lot of things.
|
|
But that's just me.
|
|
My kids would not bother at all if they were here.
|
|
They don't use it.
|
|
Even the way, I'm actually got an eight-port network switch
|
|
on the kitchen table here,
|
|
so sometimes when they come to visit for dinner or something,
|
|
the laptops and tablets and things come out
|
|
and they say,
|
|
Dad, is there a port I could use on that
|
|
and they plug in?
|
|
And so it's a new fitting on the dining and table these days,
|
|
which is, I don't know if that's ultra geeky or just realistic.
|
|
Yeah, that kind of made people
|
|
that have a multi-port switch
|
|
and they're hubbing the room table.
|
|
It works, it works.
|
|
But you see my daughter,
|
|
I'm not seeing them much,
|
|
they don't live with me at the moment,
|
|
but they do come in for a quick visit every so often.
|
|
You know, we sit the right,
|
|
because the distance apart.
|
|
But my daughter earlier on this year was doing a lot of study
|
|
and she used to like to come over here
|
|
and use this big kitchen table for stuff
|
|
and she'd say,
|
|
oh, can I just plug my laptop in?
|
|
To get a better signal than on the Wi-Fi.
|
|
But it's a fairly rare thing.
|
|
I think it's just sort of getting access to weird systems
|
|
and stuff,
|
|
or maybe the university's system
|
|
that she's using or something like that.
|
|
So it seemed like the right thing to do, though.
|
|
Maybe there's a time will come when there won't be an eight-port switch
|
|
on the table here, but we'll see.
|
|
I used to have an old BT router
|
|
and it was hacked, not by myself,
|
|
but obviously it was originally locked down to BT,
|
|
and I had a very limited number of ports on the back.
|
|
So I've got myself a cheap switch
|
|
and I used that for a while.
|
|
So I don't have something like that here,
|
|
but now we have another router
|
|
which has got a few more ports on it.
|
|
I don't actually have as many ports as I used to have,
|
|
because with the switch I had more,
|
|
but I can just about squeeze into the four ports on the back
|
|
and I use Wi-Fi for the other bits and pieces.
|
|
But I tell you, I think I noticed was,
|
|
when I got this tablet,
|
|
I discovered obviously Wi-Fi's, I think I'm very touched on this before,
|
|
obviously the Wi-Fi standards have gone up and up and up,
|
|
and my Nexus 7 was so key,
|
|
but I've discovered that my Wi-Fi speed across the network,
|
|
because just transferring from machine to machine
|
|
is way faster than the Ethernet,
|
|
so it's just surprising.
|
|
Yeah, well, yes, you're right, you're right.
|
|
I've actually got two routers in the house.
|
|
I probably mentioned this before,
|
|
but I had one that my ISP said was failing.
|
|
You know, the Wi-Fi network side was failing,
|
|
which happens.
|
|
I don't disbelieve them,
|
|
but of course the rest of it was working,
|
|
so I've actually transferred it through to the back of the house,
|
|
and I'm just using it as a bridge system,
|
|
so it's got network switches, network ports on it,
|
|
but it's also got a whole load more wireless connection,
|
|
so maybe that's why my kids tend to not to be asking for direct connection
|
|
so much these days,
|
|
because the wireless is better, but yeah, yeah.
|
|
I see that nowadays a lot of,
|
|
if you go and buy some of the more upmarket routers,
|
|
they come as a sort of cluster of machines, in some cases.
|
|
I've not really got into this.
|
|
I'm sure other people will know a lot more about this,
|
|
and I do.
|
|
I see some like the Google selling routers,
|
|
and they come as a sort of a cluster,
|
|
which you put all over the house,
|
|
and they network between each other.
|
|
I made a sort of matrix,
|
|
or whatever you'd call it,
|
|
mesh, I think, mesh networking between them.
|
|
Obviously dealing with the instance where
|
|
your reception is good here,
|
|
but not so good there, because of the walls in the wire or whatever.
|
|
Which is interesting.
|
|
It's quite interesting.
|
|
Yeah, yeah, it's funny.
|
|
I don't know, I do have people who have,
|
|
they should have had issues with the Wi-Fi and whatnot,
|
|
maybe because the house isn't so big,
|
|
and I don't know.
|
|
I was at the bottom of the garden,
|
|
and I had a video conference,
|
|
and it was working fine as well.
|
|
I don't really need any extenders,
|
|
but I think it's probably more to do the fact
|
|
that the house isn't anything else.
|
|
I think the walls are not like solar stone or anything like that,
|
|
so jobs that absorb some of my growth and whatnot.
|
|
Wi-Fi is okay for me to be.
|
|
My work in IT at the university down the road
|
|
is from here.
|
|
Again, Wi-Fi around that place was a nightmare,
|
|
because a lot of the buildings are steel framed things.
|
|
When they build a good structure,
|
|
and then they do glass fill,
|
|
or a concrete panel or something in between,
|
|
and so to get reception wise,
|
|
reception through them was a total nightmare.
|
|
No, I think I was involved with it,
|
|
but even though the guys had to do that swearing about it.
|
|
The building we were in had a sort of corrugated iron skin on the outside.
|
|
It was not corrugated iron,
|
|
but it was a sort of metallic skin on the outside of the building,
|
|
because it was trendy in architects thought it was good.
|
|
Of course, that led to all sorts of problems as well.
|
|
Couldn't get a...
|
|
Still can't get a phone signal in the place.
|
|
You have to go out to use your phone.
|
|
So, also, it's a clever thing.
|
|
Wow.
|
|
That's all court, yeah.
|
|
I've got to...
|
|
It's just a standard router that came with ISP,
|
|
and it got slated.
|
|
The router, when it came out,
|
|
and just recently I got an alternative stone.
|
|
If you send it for another so many months,
|
|
we'll make it cheaper, and you'll get a new router.
|
|
So, I've got that anyway, but I don't want a new router.
|
|
I'm happy the one I've got.
|
|
Just give me the cheaper contract,
|
|
but it no longer end up with my new router,
|
|
but it doesn't even take me to the box.
|
|
So, I'm quite happy with this one.
|
|
It's all set up, and I can't be bothered
|
|
if we can figure it out on a router.
|
|
So, I've just missed it.
|
|
I've just missed it.
|
|
I've just missed it.
|
|
It's...
|
|
They seem to be fairly disposable these things, don't they?
|
|
My daughter had a...
|
|
when she was away at university,
|
|
living in a flat with some friends and stuff.
|
|
And it came with the router,
|
|
and then at the end of the contract, when they left,
|
|
said, well, do you want your router back?
|
|
Said, oh, no, you can have it.
|
|
So, it's in this house somewhere,
|
|
so I'm not quite sure what to do with it.
|
|
It's probably something you do with it.
|
|
It's probably hackable,
|
|
but there's too many things to play with here,
|
|
so I haven't done anything with it.
|
|
Yeah, and that's a double of these things.
|
|
Like the BT, this one, that one will be a lot to talk talk.
|
|
So, I'll give you a couple of other talk talks
|
|
I'll mix that up.
|
|
So, you won't really use it,
|
|
unless you hack it as you see.
|
|
Yeah, yeah.
|
|
There's also facts that you can come across.
|
|
I've not looked on looking for that particular one,
|
|
but other ones I've seen where people show that,
|
|
if you bridge these two points on the circuit board,
|
|
then you can do a fact you reset on it,
|
|
and then your liberty to do whatever you like,
|
|
even put new firmware on some of them.
|
|
So, you know, some of the ones that are compatible
|
|
with OpenWRT and that type of thing.
|
|
Which is feel than used to be,
|
|
but you can do it.
|
|
Oh, yeah, it's OpenWRT.
|
|
I looked into that,
|
|
because I had myself one of these slugs.
|
|
I didn't actually end up doing anything with it,
|
|
but remember the open...
|
|
What was it doing?
|
|
Yeah, the slug thing.
|
|
Yeah, yeah.
|
|
I don't remember.
|
|
It was probably nine mores.
|
|
Yeah, yeah.
|
|
I've known a number of people have these over the years,
|
|
and they were quite a thing at one time.
|
|
They're a bit slow now, I think.
|
|
Yeah, well, that's it.
|
|
I never really got anywhere with it.
|
|
I had great plans for doing something with it,
|
|
but I never did.
|
|
So, it was always the time, really.
|
|
Yeah.
|
|
I am in the early days of household computing and stuff.
|
|
I bought myself,
|
|
way before the Raspberry Pi era,
|
|
I bought myself one of these plug computer things,
|
|
which was...
|
|
What was it called?
|
|
Oh, Shiva plug.
|
|
Shiva plug.
|
|
So, that's just a little arm processor in a box.
|
|
It wasn't actually part of the plug,
|
|
but some of them were.
|
|
It was a separate box on the end of a cable.
|
|
But it ran devian,
|
|
and I used to use it quite a lot, actually, for a while.
|
|
It was pretty weedy, especially when the Raspberry Pi started to come out.
|
|
It looked quite feeble.
|
|
But I still got it, and I was thinking the other day,
|
|
I wonder if I could actually put something useful on there
|
|
and get it back to life again?
|
|
So, it's not actually dead,
|
|
but it will have a very, very, very old Linux version on it,
|
|
and I think a lot of the support for these things is gone.
|
|
But be quite nice to resurrect it just so I can say,
|
|
you know, it's still usable.
|
|
Yeah, I remember with these Shiva plug things,
|
|
looking in the envy of thinking,
|
|
oh, I should have bought that rather than the slug thing,
|
|
because I think we bit after the slug,
|
|
and they did look a bit more fun,
|
|
and there was a bit more you could do with it.
|
|
So, well, I remember it was a typical Cany Scott.
|
|
I bought this thing.
|
|
I've not been buying another one.
|
|
No, no, it's probably very wise.
|
|
I changed my own issue once the Raspberry Pi came out,
|
|
and started to buy them whenever they took me,
|
|
because they're so relatively cheap,
|
|
especially the zeroes for a five,
|
|
or whatever it was in the first instance.
|
|
Amazing, so you have a few of those knocking around the house.
|
|
Yeah, I never bought a Pi zero,
|
|
and I never got down to that,
|
|
and it's so cheap,
|
|
but I've got three or four Pi's around the house,
|
|
and I think there's a Pi three years,
|
|
and most recently I haven't got the four,
|
|
but yeah, I've got very, very useful,
|
|
great devices, you know.
|
|
Absolutely.
|
|
But Pi four is a bit of a mixed blessing,
|
|
still I think it's with all the heat issues,
|
|
and the fact that you can't boot them off the USB,
|
|
which is what I'd been doing,
|
|
which is the way my Pi three is set up.
|
|
I've just got the one three, I can't remember that.
|
|
So I've got SSDs,
|
|
and plugged them into these various machines,
|
|
and it was great to be able to put the entire operating system
|
|
on the SSD, and then boot it from there,
|
|
without the need for an SD card at all, you know.
|
|
That was entirely possible,
|
|
but it's not possible with four at the moment.
|
|
So you've dropped out there, Dave?
|
|
Oh, you hear me?
|
|
Yes, yes, but it was great to be able to put the entire,
|
|
and then you dropped out of that moment out of my ear.
|
|
That's very strange.
|
|
You hear me still?
|
|
Yeah, loud and clear.
|
|
Maybe in my finger slipped off the push to tool button or something.
|
|
No, just to say that being able to boot off the SSD
|
|
without needing an SD card at all,
|
|
I thought it was quite good,
|
|
you can just do the boot of the SD card on the Pi4,
|
|
and then do the rest of the SSD,
|
|
but I haven't got around to setting that up yet.
|
|
But why didn't it make that available from day one, I don't know?
|
|
Yeah, I've never taken any of that.
|
|
I've always been very, very happy with the SD card.
|
|
It's funny, people have complained,
|
|
I've had people complain,
|
|
oh, I've been, about, about, about,
|
|
tracking SD cards in their Pi,
|
|
and also about the sound as well.
|
|
And it's funny that the SD card,
|
|
I've never had a single SD card failing any of my Pi's.
|
|
I think I've probably still got the original SD card
|
|
that had my very, very first Pi kicking out here somewhere.
|
|
And I've got a Pi3,
|
|
which runs every single day, non-stop,
|
|
and it's never crashed,
|
|
and I've upgraded the card a few, a couple of times.
|
|
And all the audio as well,
|
|
you know, okay, it was a little bit clicking,
|
|
popping in the early days,
|
|
and I used a lot of processing,
|
|
if you checked, you know,
|
|
the top of whatever you'd see,
|
|
but using a bit of the processing.
|
|
But now, there's so much firmware hacking going on
|
|
by the Pi Institute, you know,
|
|
that it uses halfway any processing,
|
|
and I think I'll do sounds great.
|
|
I mean, I use it on my colours headphones,
|
|
and certainly more than good enough for voice,
|
|
and I'd probably even good enough for music,
|
|
as well with Arca, you know?
|
|
Yeah, yeah, yeah, that sounds good.
|
|
Yeah, you're right, it has come on a lot, hasn't it?
|
|
And a lot of clever add-ons,
|
|
hardware add-ons for the pies,
|
|
for the improved things a lot.
|
|
It's a very fancy audio add-ons.
|
|
I see quite expensive ones,
|
|
in some cases, that you can, you can burn.
|
|
So yeah, a lot of possibilities,
|
|
sticking with the Pi, regardless, I guess, is the way.
|
|
I haven't had one SD card fail, I think.
|
|
I think it did.
|
|
My original Pi,
|
|
the first generation of the Model A,
|
|
or whatever it was called.
|
|
So what it was called, I've forgotten.
|
|
It's just here on the shelf beside me,
|
|
but I was using that for a while,
|
|
as a cups driver for my old inkjet printer.
|
|
It's a laser jet, now it's just an inkjet.
|
|
I didn't, I didn't waste my show about it,
|
|
but it failed eventually than the Pi.
|
|
And I think it was the card,
|
|
though I've not actually investigated.
|
|
It's here because I was going to try and resurrect it
|
|
with a new card and put one of these very minimal versions
|
|
of something on it,
|
|
and, according to Miranda,
|
|
did a show recently where he was talking about.
|
|
And it was tiny cool.
|
|
Did he put one more of these?
|
|
So I was going to give that a shot,
|
|
to see if that was usable on the top.
|
|
Yeah, tiny cool.
|
|
I've had a wee clip of that many, many years ago.
|
|
That was fun.
|
|
And quite amazing, we distro.
|
|
And I was speaking to you,
|
|
I think last time in time,
|
|
to work with this small minimal distro,
|
|
I've been playing with, before,
|
|
it was populinix, that was a one.
|
|
I couldn't remember the name of it,
|
|
but populinix.
|
|
Well, you knew that, didn't you remember?
|
|
Is that still going?
|
|
I don't think so.
|
|
No, I think it's moved on.
|
|
Somebody was talking about that on a podcast recently.
|
|
I don't remember the details.
|
|
I think it's changed name,
|
|
and it's been sort of subsumed into something else.
|
|
I believe, but I don't know the details.
|
|
Yeah, well, funny feeling,
|
|
did it not bark when you put it up or something like that?
|
|
Something better than that.
|
|
I think I ran it because,
|
|
did it not come with a bunch of useful tools
|
|
for investigating discs and that type of stuff?
|
|
So you could use that as a means of looking
|
|
over a possibly dead disc from another system.
|
|
Possibly.
|
|
Am I confusing over something else?
|
|
Well, am I, am I, am I, am I, am I, am I, am I, am I, am I,
|
|
maybe I'm getting confused with pop,
|
|
the different type of populinix.
|
|
Well, I remember, was it dance mallinix?
|
|
Was that the other one I tried?
|
|
I can't remember.
|
|
There was a few I did try.
|
|
There was one I was using on a machine,
|
|
which, which wasn't mine.
|
|
There was just a way to get a,
|
|
a Linux prompt to experiment sort of thing.
|
|
I can't remember whether it was dance mallinix
|
|
or popularinix or one of these,
|
|
these ones anyway.
|
|
So, but I can't remember very much about it.
|
|
It was really interested in getting that,
|
|
a bash prompt rather than else, you know?
|
|
Absolutely, absolutely.
|
|
No, I think I just played around it.
|
|
I've seen years and years and, you know,
|
|
and it's too, too, to any great degree.
|
|
But, too, it was cool.
|
|
Maybe it was an old laptop or something else.
|
|
I ran it on a curry.
|
|
I really can't remember.
|
|
I still have,
|
|
still got my daughter's old laptop,
|
|
which is pretty weedy now.
|
|
I'm trying to think what to put on that.
|
|
So, trouble is though.
|
|
You go and resurrect old machines.
|
|
Then,
|
|
there's always, there's not always a good use on them.
|
|
And with the Raspberry Pi,
|
|
they're not using it much power.
|
|
Whereas, you know,
|
|
using old desktop or an old laptop,
|
|
then you can potentially have this thing running,
|
|
running along each time.
|
|
And then using up quite a lot of electricity.
|
|
It just goes against the grain a bit.
|
|
Yeah, yeah, that's right.
|
|
You were talking about the,
|
|
what's it now?
|
|
Or it was a print server using cut sandwiches.
|
|
I did that for a while as well,
|
|
on my old compact server.
|
|
And that I was planning on using
|
|
my Raspberry Pi to take over from that.
|
|
But it ever happened.
|
|
And I just thought,
|
|
I kind of moved it close to the print,
|
|
the PC anyway,
|
|
so that I could just plug this USB plug in and that'll fix it.
|
|
That was just too easy.
|
|
Yeah, yeah.
|
|
It was just one of those challenges I set myself.
|
|
And it was really happy when I actually managed to solve it.
|
|
In fact, it's one of those printers with a scanner in it.
|
|
And I think within the past couple of months,
|
|
maybe a bit longer now,
|
|
my daughter came in saying,
|
|
Dad, I've got this thing.
|
|
Can you scan it?
|
|
And I was thinking, wow.
|
|
And yes, the answer was yes,
|
|
I could scan it from my desktop machine,
|
|
believing me,
|
|
the other one was in the front of the house.
|
|
The printer.
|
|
And I was able to grab the scan off it still.
|
|
It was quite surprised that
|
|
I've got to put a different pie on it to act as the cup server.
|
|
I knew a pie.
|
|
So yeah, it did work.
|
|
But it's just once a year you get asked to do things like that.
|
|
I find that.
|
|
And I've very, very rarely scanned stuff myself.
|
|
Yeah, I've got a bog stand-up sort of,
|
|
kind of scan off which is compatible with on it.
|
|
That works fine.
|
|
Canon scan, I think it is.
|
|
But it's funny, I am.
|
|
I had, when I had my network printer set up through cups
|
|
on my server.
|
|
I had a, the printer could print onto DVDs and CDs.
|
|
You remember, and that was all the rage.
|
|
So there was a dedicated CD DVD printing application
|
|
that came with the printer,
|
|
or maybe I bought a Canon member.
|
|
And of course, that only ran on Windows, of course.
|
|
I guess it was maybe Windows XP or something like that.
|
|
And I had my, and of course I didn't.
|
|
I didn't really.
|
|
I mean, I tend to use Linux when I can.
|
|
And I very rarely use Windows.
|
|
But I had this happen.
|
|
Of course, there's an option to print to a network printer.
|
|
And it's not the standard Windows network printer.
|
|
It's, it's where you'll know more, I can't really remember
|
|
enough little bit of cups now.
|
|
But it was actually able to get Windows to talk this cup server.
|
|
And it would actually spit out a desk.
|
|
No, I've got an error at the end of it.
|
|
Or there's a critical error that didn't work.
|
|
And then out came the desk.
|
|
And I said, oh, that's my perfect way.
|
|
So, yeah.
|
|
So I was amazed.
|
|
I could print something in XP through these cups on my server.
|
|
Let's say the room.
|
|
So I think.
|
|
The cups are actually pretty good.
|
|
We did a lot of work with that at work.
|
|
You know, we used it a lot is what I mean.
|
|
Because in the, in the various days when PCs appeared,
|
|
getting stuff printed off PCs was a, was a real pain.
|
|
And there were, there were various.
|
|
There was things like LPR.
|
|
It was a thing called LPRNG.
|
|
It was called LPR next generation.
|
|
And then cups, as I recall, that let you do some quite smart things.
|
|
We had a photocopier.
|
|
It was a big photocopier, which I think it was mainly used by the department
|
|
to produce documentation and stuff.
|
|
It was a huge great thing.
|
|
And it, I discovered, it was on the network.
|
|
It can put on the network.
|
|
And I discovered that it was actually just a printer.
|
|
So you could print, so you could do double-sided A3 with it.
|
|
And I think you could also print stuff.
|
|
And it had a binding capability.
|
|
And no idea why we had this sort of printing and binding capability
|
|
in the, in the department.
|
|
But we did.
|
|
And I say to be the only one who used most of it at one time.
|
|
Great.
|
|
Great stuff.
|
|
Yeah, very good.
|
|
Of course, because the tattoo did an episode, one of the great episodes,
|
|
because it became a, by mistake, it became a bit of a cups' experience.
|
|
So, and I know what you, it was since I think about how he sort of stumbled
|
|
across the bit behind, you know, the cup server.
|
|
And you know, you look through your suit as a web client.
|
|
It seems to me, you pop your address in the bar at the top.
|
|
And then you get right into cups.
|
|
So I think it's like, oh, this is the stack, it's a new little sort of thing, you know?
|
|
Yeah, yeah, it's got a lot of features.
|
|
It's really quite cool.
|
|
And a lot of these network printers and stuff also have quite sophisticated interface.
|
|
You can access through web servers in my fairly limited experience.
|
|
So, but yes, the whole business of printing on fancy stationery and stuff is quite fun.
|
|
But the university worked out, there was a point at which our land printers on a mainframe,
|
|
we used to generate the student matriculational cards.
|
|
And they had special stationery, which had, you know, sheet of paper with a card,
|
|
stuck to it.
|
|
And the printer would have to go and print their name and, you know,
|
|
a matriculation number, all sorts of stuff on this card.
|
|
And then spit it out.
|
|
And then somebody took the card off the sheet of paper and handed it to the student,
|
|
because they've got pre printed for the students arrived.
|
|
And, yeah, so I was a little bit involved in in that and say now, I can so forth.
|
|
It is enormous fun.
|
|
It's a university is a stranger like that, because you can, there's a certain element of messing about
|
|
or, you know, having a bit more leisure to get a thing to work, or there was.
|
|
That was the case back in the 80s and 90s and stuff, less so now.
|
|
But, yeah, a lot of fun in that area.
|
|
Yeah, it's funny.
|
|
I think, I think, I don't know whether it's an age thing, you know,
|
|
whether, you know, you just remember things with rose tinted glasses and stuff.
|
|
But I hear this all over and over again that, you know, you had more time to do things in the past
|
|
and things more satisfying, you know, you get hands on and there's less and less in that now.
|
|
It's just, everything's just, just sit on the computer and say,
|
|
we used to do big print jobs.
|
|
We did with, it was like folded,
|
|
don't make friction with these kind of, what do you call it?
|
|
If the folded sheets, they go, you know, left, right, left, right,
|
|
and a big, big pile, basically.
|
|
You can go back and forward and come in and tear bits off,
|
|
you should do big print ones sort of thing of computer program listings and whatnot.
|
|
So, yeah, that was, that was.
|
|
Yeah, that was pretty much the stuff I was involved with when I first started working in IT.
|
|
Fan fold, 132 column line printer paper stuff.
|
|
The sort that you, you would get and it had alternate green and white bars on it or something like that.
|
|
That's right, fan fold, I couldn't think of a word.
|
|
That's exactly it, yes.
|
|
It's quite holds down the side and all that sort of good stuff.
|
|
Yeah, yeah, we also work for these great big, the able of discs.
|
|
You know, huge big things are like a big giant pizza,
|
|
that's sort of like a pizza box.
|
|
And you pull the front face down on the device and on the drive.
|
|
I mean, it was a size of a coffee table and it would hold,
|
|
I think it holds a hell of a massive five megabytes of data.
|
|
And see, you slide it into the front, the machine and you've lifted the wall.
|
|
I was almost like a bit like a big, often nut or almost like a,
|
|
so if you were a toaster or something, you'd pull the thing down and you would slide the big,
|
|
drive into it and then push it back up again and you'd flick a switch from,
|
|
from a load to run and it would slowly build up and build up and build up and you'd,
|
|
you know, a big clunk and a big flag would pop up this show that the heads had engaged.
|
|
And yeah, five megabytes of hell.
|
|
Yeah, I do remember those times, oh wow, yeah, yeah.
|
|
I probably told the story before, but in 1987 I remember the year very,
|
|
very clearly because at the University I was at the,
|
|
because it was in the days when universities used to get funded centrally for their
|
|
computer facilities and they got mainframes and stuff.
|
|
We finished the seven years that we were funded for our mainframe at the time
|
|
and we were allowed by government.
|
|
This is a government body that had all that money to buy a new,
|
|
a new machine for the students and stuff.
|
|
And we ended up spending about 1.1 million,
|
|
which is a lot in 1987 on a couple of deck faxes.
|
|
Yeah, one point, one point one million it was,
|
|
it felt a big real two massive big machines networking with handle
|
|
or something like 200 and odd simultaneous connections from terminals,
|
|
of course, and they had always a ray of big machines with disks in them.
|
|
So there was like a stack of disks one on top of the other and they stood almost as
|
|
high as, you know, sort of fridge freezer does these days.
|
|
You know, the sort of big, big almost walk in fridge freezes you see nowadays,
|
|
each one of these and they had like three disks in them.
|
|
And the total disk capacity for this 1.1 million quid's worth of machine was
|
|
one gigabyte from the entire university.
|
|
Wow.
|
|
People just can't comprehend how things would, you know,
|
|
if you have a certain age, you just wouldn't comprehend that.
|
|
You know, I think I'm sure the first company PC in office,
|
|
I think there's something like 100,000 pounds,
|
|
something like that.
|
|
I can't remember.
|
|
Something crazy like that for one PC or something like that.
|
|
Yeah, the things were just so expensive.
|
|
Even a dot, even a dot meat expenter would be
|
|
positively expensive for the everyday person, you know.
|
|
Yeah, yeah.
|
|
It was all, it was probably, they were so rare.
|
|
I guess that was part of why the process was so high.
|
|
They wouldn't become commodities at that point.
|
|
There's also a massive markup on it, I suspect.
|
|
It's the machine that we got rid of in 1987.
|
|
It was a boroughs mainframe, boroughs being a company that's long gone now.
|
|
But great, great chunk of a thing.
|
|
And I think two guys arrived in, we sold it for square.
|
|
Two guys arrived in sort of low loader thingies
|
|
and thought left did it the bits of it into the bag of it.
|
|
And you can see the suspension on these things sort of way down at the bottom.
|
|
No way they wanted to go over any significant bumps.
|
|
But the stories once, those were going to be sold into Africa.
|
|
Are they probably going to be put back into years again?
|
|
You know, it was a, it was a very scientific world then.
|
|
Yeah, yeah.
|
|
But I think we tended to have a equipment that was, you know, old heart,
|
|
probably even when I joined, because we were using punch card machines.
|
|
They were amazing because they were like, it's like a big hoover.
|
|
You know, you would, you would power up the whole hopper back.
|
|
I need to have your stack of cards, which you were very careful not to drop.
|
|
Because if you did, you'd have a hell of a job getting them back in the right order again.
|
|
So put them in a hop bar and you push the button and it would build up.
|
|
For all of us, it seemed like a great big hoover.
|
|
I need to get a giant sucking noise.
|
|
I would just fly through this machine or often not just jam halfway through.
|
|
And that was to boot the machine up, you know, computer up.
|
|
Yeah, I see those sorts of things.
|
|
Yeah, the boroughs machine that we had before had, it was all, love it was punch cards.
|
|
And as a student, I had, you used to get a thing with like a small suitcase,
|
|
which was the width of a 80 column punch card.
|
|
And you, you put your card deck in there and then it was sort of locked.
|
|
It was locked the lid down and there's a handly controller around it.
|
|
Because, well, the target, if you, if you ever dropped that a lot, as you say,
|
|
you find and putting them all back together in order of the nightmare.
|
|
Even though in those days people would, there was a machine that would put sequence numbers on them,
|
|
on the columns from, whether it was 72 onwards or something,
|
|
they'd put a sequence on them and you could actually take that deck to a collater
|
|
and get sorted according to that number.
|
|
But you'd need to have been really careful about putting anything you added to that card deck
|
|
you would have to make sure that you put numbers on it on the cards which interleaved
|
|
in the right place with the cards already there, you know.
|
|
So yeah, had a little bit, so there's never dropped one.
|
|
Well, we never had anything as fancy as that.
|
|
You know, we were the collaters if we dropped it, we had to fix it.
|
|
And then I've seen, I've seen great big piles up in the desk, you know,
|
|
a few feet high sort of thing, but I've seen people carrying big piles of them.
|
|
You know, you just tap rubber bands out of it.
|
|
You know, that's how we was going to keep them together with a big rubber band.
|
|
Yeah, yeah. I've seen that as well. I've seen that as well.
|
|
I once saw that this was a Manchester University when I was a student.
|
|
I saw a guy come from the computer department with his punch cards
|
|
and a big pile of printer on the top of it.
|
|
There's something which must have been six, eight inches thick or something like that,
|
|
maybe even more.
|
|
And he had that balance on top of his cards and he walked around the corner
|
|
and he'd have anything on the top of the printer just wet down and it was a windy day.
|
|
And then between the buildings of the university,
|
|
you used to get some incredible, you know,
|
|
winds and little mini tornadoes and stuff.
|
|
And his entire stack of printout just got sucked up into the air by a mini tornado
|
|
and disappeared.
|
|
It was tragic.
|
|
I think it was completely wrecked because it sort of mashed up and sent all over the place.
|
|
Oh, yeah, yes.
|
|
Of course with the dice.
|
|
Oh, Craig, that's something else.
|
|
You're talking about suitcases.
|
|
Just reminding me, these Diablo discs, as I say, they were.
|
|
I mean, if you imagine the size of the, you know, the seating,
|
|
the seat cushion of the seating portion of a room office seat.
|
|
And it was probably that diameter, maybe even more than that, in fact.
|
|
And they had case thing, maybe, I would lower the low and then she'd eat something like that.
|
|
And I remember that are with a clerk in office and he was given this fancy device,
|
|
it was a big, it was a big sort of aluminum clad suitcase.
|
|
And it looked, honestly, it looked like something out of either a mission impossible thing
|
|
or something, maybe James Bond or maybe Joe Ninth or something like that, people have certainly
|
|
as well know all these sort of things. It was a silver chrome thing all around even chrome
|
|
and really really expensive. What's going to be inside this thing is amazing. You know,
|
|
it looks so, so high-tech and you open it up and it was almost like a record deck thing
|
|
and you basically placed the Diablo disc on this device and it had base attachments
|
|
he clipped on in various places and opened the, there's a kind of slice it would open
|
|
so the head could get in and then there was like vena calipers that lay on top of the
|
|
disc surface and you could rotate the disc and look for wobble, you know, as a disc
|
|
buckled by more than x percentage if it is then it will refueled and all this. It's
|
|
just to check the integrity of the disc sort of thing, you know.
|
|
And of course the heads of the disc was too wobbly I think.
|
|
Yeah and that's exactly it, you know, so the whole host of, you checked for, you checked
|
|
that sort of edge to make sure it wasn't moving in and out basically and also up and down
|
|
as well and in VH other tests he did another thing, you know, and there was counters and
|
|
all sorts of things but I thought it just looked so high tech, I think it came from America
|
|
typical, you know, it helps the Americans make things look very flashy and look, you
|
|
know, like something out of a movie sort of thing, I was just to pass with the way it
|
|
looked basically.
|
|
Yeah, yeah, some of the technology back in those days it did look very, very impressive
|
|
isn't it? Yeah, yeah, it's, so I was, something I was seeing recently, I can't remember
|
|
where I saw it on the, on the web some web apps, there was some excitement over the ability
|
|
back in the day to visualise the contents of magnetic tape, I think maybe something like
|
|
that. I have seen that done, you know, magnetic tape has got sort of recording in, I mean
|
|
computer stuff, half inch stuff, it did get recorded in chunks with tape marks in between
|
|
and stuff like that, so there was this thing, there was a liquid you could get which was
|
|
very, very, very fine iron filings in some sort of a medium, I don't know what it was
|
|
like alcohol or something like that and you had to put your tape out onto a flat smooth
|
|
surface and paint this stuff onto it with a little, little brush thing and then it would
|
|
all align itself according to the magnetic recording on the tape, so you could, the idea
|
|
was that you could spot in a faulty tape where to cut it or splice it around where the
|
|
tape marks were, because the tape marks were just sort of clear, clear spots on the tape
|
|
so yeah, I remember seeing somebody doing that and then being taught how to do it was
|
|
often, because I had the job of doing some mag tape restoration or recovery after they
|
|
got wrecked, you know, they got jammed in the machine and stretched and then you'd cut it
|
|
at the coming point and then try and re-read from the sort of last good spot on the tape,
|
|
I'd never seen them spliced actually, because it would be really hard, they moved so fast
|
|
if a splice caught inside the machinery, it would wreck even further, I would imagine,
|
|
but yeah, it's, oh, it seemed like clearly cool stuff now, it sounds okay, I can read,
|
|
no?
|
|
Well, it's funny, I know we're talking about, there was, I saw an episode, because it was
|
|
a series, it was in the 80s when Channel 4 here in the UK was called The Secret Life
|
|
of Machines and it was done by, I think, a chap called Tim Hunkin and he was, he did
|
|
one on the video recorder and of course, he took it from the very early, so he just
|
|
didn't know how, how, how, how did we first record things, it was about wax cylinders
|
|
and whatnot and all the way up to eventually get the video recorder, oh, I just had to
|
|
climb this just now, hold on a wee second, and that was my mother trying to call me, she
|
|
wondered what's happened and hope she doesn't try again, oh no, anyway, so they, they've
|
|
actually got to the, you know, magnetic recording and he swiped stuff onto the surface of
|
|
the tape to show, he actually recorded blips on a bandsaw and they had a coil around the
|
|
bandsaw, it's a bandsaw went down slowly and then made the magnetic, moving coil,
|
|
licked up and down to show how we recorded it, it's really clever, he's got a lot of clever
|
|
ideas and now, what else did he do now that I'm telling, boy, so what he did eventually was

|
to show what a tape is, he took, he took a piece of cello tape and then he got some iron
|
|
filings and rubbed it over the sticky bit of the iron filings and then it looked into the tape
|
|
mechanism of a tape recorder, I know I'm real to real, but it just held both ends basically
|
|
and as they let it slide through his fingers, you see, this is recorded in a sticky tape and rust,
|
|
and he put it back into the heads and pushed the play button out of the cave.
|
|
Wow, yeah, yeah, the technology was, it was effective, but it was, it was very primitive,
|
|
I guess. Yeah, I was listening, funny, I was listening, I've got one of these,
|
|
you know, it's funny, I've got one of these Google speaker things, which I got given,
|
|
and it was, it would have been a thing I would never, ever have bought, you know, but this is one of
|
|
these things, you know, I've got given it and actually I found it useful, so I ended up keeping
|
|
the thing, and it was talking about, thank you for listening to this, and if you have a
|
|
certain age, you might have been listening to, instead you could have been listening to
|
|
an invention tapes and such like an invention, and I feel old enough, you won't even remember
|
|
the 8 track, and of course I looked at Mrs. X's, do you know what an 8 track is, can you remember
|
|
an 8 track? Oh no, I don't know what that is, so I'd explain what an 8 track is.
|
|
Yeah, yeah, I think I had a cousin here who had an 8 track player in a car or something,
|
|
they weren't all that popular over here as I recall, but they did, they did exist, I have seen
|
|
Yeah, you know, I never had one, I don't know, it's probably a little bit before my time may be
|
|
just, but I have seen one in maybe an operation, and even more interesting I think I saw was,
|
|
there's the Museum of Communications, which is over, I don't know, obviously for people,
|
|
most of them, there's our Museum of Communications over, let us say to the, what is it now,
|
|
it's over, let us say to the fourth road bridge, I can't even remember where it is now, but anyway,
|
|
it's a museum, and I've got some really unique pieces of technology, and there's a device that
|
|
came from Germany, and it uses, it's like a cartridge thing, and it's got a tape, and it runs through,
|
|
but it's surely the thing about it, it isn't, it isn't based on magnetism, it's actually
|
|
almost like a record, a bit in tape form, so that the needle gets pressed onto the tape, and as a
|
|
tape goes past, it plays a cyclist, and I think depending on where you place the head, you could have
|
|
a number of recordings, different tracks, which you can just select, and it will, by switching from
|
|
one groove to the next, and it's astonishing, it's just, you know, there's no magnetism,
|
|
toruses, it's grooves, and on a tape. Oh, I've never heard of that, that's amazing, I'd like to,
|
|
yeah, I'd like to find out where that isn't going, it sounds like a good thing to see.
|
|
Yeah, they do the whole host of things, this is the museum of communications, if anyone's in
|
|
Edinburgh area, it's only on in certain things of the year, they had a many storage or exchange,
|
|
which you can, they've got different things in different years, so you don't know what you're
|
|
going to see with the website, and it's called the Museum of Communications, and let's say,
|
|
one of the years I had a wee many storage, storage or exchange, and you could pick up the
|
|
handset, and turn the dial, and you could heal a whole lot of them, flip to mechanical things,
|
|
clunk and round, and brazen, and drooping, and all that sort of fascinating stuff.
|
|
Yeah, I do remember them, there was a guy, when I was a student at Manchester University,
|
|
there was a guy who was controlling a bank of cameras or something, using an old,
|
|
remained at Stroudger, because it basically pulsed, was it some sort of a motor, or was it
|
|
stepper motor, was it solar noise or something, because basically you moved an arm around
|
|
an arc, I think, didn't you, and it made different connections as it went along, something like that,
|
|
I'd only seen this once or twice, but he built a machine, but let him take timelapse,
|
|
I think that with timelapse pictures of animals or some sort, I can't remember what,
|
|
just remember him saying, or he went to see my new timelapse machine, and it was one of those
|
|
inside it. Yeah, that's exactly how it works, it's it's electoral magnets, there's coils
|
|
wrapped around that, I'm a ferric core, I guess, and when they put power through the coils,
|
|
it turns into a magnet, and draws a thing to the next contact, that's how he's like to a magnet,
|
|
I'm sure told the story before, but I believe it was a funeral director or something in America,
|
|
it came up with the idea, and it was through necessity, again, this is in the secret life
|
|
machines, if you, I think, if anyone gets a chance to watch it, I would really recommend it,
|
|
and they were saying that what happened was that there was a, there was a
|
|
fist funeral director, and he noticed that the business was getting quiet, and he couldn't work
|
|
out what we're going on, and then they realized that one of the neighbors or one of the relatives
|
|
was going to the funeral directors down the road, and passing on information about people who
|
|
had deceased, and of course he was nicking all these business, so so I'm going to fix this,
|
|
you know, or that's it, she would, she worked in the telephone exchange, that was it, that was it,
|
|
so she was finding out all of all these deceased people, and so he said I'm going to, you know,
|
|
find a way of cutting out the middleman, and having my own exchange, so I don't need a person
|
|
to do this, or something to that effect, and it was through necessity, he wasn't even in an
|
|
engineering, he just built it out of bits and pieces, you know. That's how some of the best ideas
|
|
get done, I think, or used to be anyway, probably got two technical. Yeah, that's quite cool,
|
|
that is very cool. Good stuff. Well, we've been chatting now for, getting on for 50, 51 minutes
|
|
going to this, so do you want to carry on, and you want to call it quits fairly soon? Yeah,
|
|
it's probably done enough, I mean, I was going to talk about, I wasn't going to brief a talk
|
|
about how things are, you know, we've never got on to talking about... No, maybe we should do
|
|
that another time, I don't know, because we're going to have it that long. Yes, it's typical, isn't it?
|
|
We say, Liam got much of an agenda, there's a few things to chat about, and then the thing just
|
|
goes on and into all sorts of areas, but yeah, we were originally planning to just sort of cover
|
|
how we've been coping with all the lockdown and everything. Well, maybe we get a good excuse to
|
|
do this again before too long. Yeah, yeah, what I could say is that there's, I know that everyone
|
|
finds some people finding more difficult than others, but I don't know, I'll tell you why not,
|
|
it's just too complicated, maybe talking out to them, because we'll get all embroiled in the
|
|
losses we also. Yeah, I think that's enough to you, I think. Yeah, okay, fair enough, we'll call
|
|
it quits at that point and say goodbye to everybody, okay. Yeah, so how do we say it? How do we,
|
|
how do you, you create kin and we finish off a kind of number? Yeah, so we say something like
|
|
hanka, and then the other one says public. Radio, yeah, yeah, yeah, okay, bye.
