02:53:05 <coppice> A London A level maths paper from 1948 is very very similar to one from the mid 70s, and then they started going down and down

10:52:10 <steve30> hi
10:52:16 <Halcyon> Hey Steve
10:54:17 <steve30> I wonder whether I should take the risk of going out somewhere
10:55:02 <Halcyon> My shoulder hurts :(
10:55:29 <EEVBlog> New EEVBlog Tweet: RT @TheAmpHour: This week on the show, @eevblog and @Chris_Gammell discuss downsized labs, flex PCBs, arsonist robots, PCB manufacturing, F…
10:55:51 <steve30> Playing with IP phones is making me run out of Ethernet ports on my switch

11:07:05 <steve30> I don't think I'll bother going out anywhere. Too wet.
11:09:54 <Halcyon> I need to go to the shops
11:14:22 * steve30 hugs Halcyon

12:19:35 * Ampera hugs Halcyon
12:19:49 * steve30 lies down on halcyon's keyboard
12:23:39 <steve30> I've got a pile of old jeans in the loft, all with holes in them. Don't know whether to throw them out or try and repair them.
12:39:35 <Ampera> steve30, make jean micarta

13:31:47 <Halcyon> Hey Ampera
13:35:57 <coppice> Accidental Suspension sounds a bit lynchy
13:37:29 <Halcyon> Depends where the holes are steve30 ;-)
13:37:45 <steve30> Knees
13:37:58 <Halcyon> That can still be taken sexually :P
13:38:19 <steve30> How? Is knee sex a thing now?
13:38:28 <Halcyon> Been on your knees too much ;-)
13:41:25 <coppice> not too much. just enough
13:44:21 <steve30> Maybe I'll go to bed now

14:01:22 <Ampera> how do
14:01:31 <Halcyon> Not too bad
14:01:36 <Halcyon> My shoulder still hurts :(
14:01:42 <Ampera> why does it hurt
14:01:52 <Halcyon> Pinched a nerve or something
14:01:55 <Halcyon> I dunno
14:02:44 <Halcyon> It's been like this for 3 days or so
14:03:12 * Ampera smacks Halcyon with a large bottle of aspirin
14:03:26 <Halcyon> Meh

14:06:56 <Guest|71972> hi
14:07:03 <Halcyon> Hi
14:07:07 <Ampera> hi
14:09:29 <Guest|71972> whats everyone up to
14:09:45 <Guest|71972> what do people do here? I have never jumped on before
14:09:48 <Halcyon> At home, installing Windows applications onto Linux :P
14:09:55 <Ampera> We sit here and try not to let the pressures of life get to us.
14:10:00 <Halcyon> Just chat, that's what IRC is
14:10:25 <Ampera> I thought IRC was basically a fancy scrying mirror
14:10:34 <Halcyon> :P
14:10:37 <Guest|71972> so everyone is on here through the EEvlog then?
14:10:53 <Halcyon> We're all fans of the channel/forum, yes
14:11:26 <Ampera> If you intend to stay I suggest you look into a real client. The web chat is only meant for occasional drop-ins. Most of us have quite complicated IRC systems and clients to ensure we're on here 24/7
14:11:35 <Halcyon> *nod*
14:11:39 <Halcyon> Hexchat is quite a good one
14:15:03 <Ampera> you know what sucks about where I live
14:15:11 <Ampera> I have to drive around 200 miles just to get to a bar
14:16:01 <Halcyon> ?
14:16:07 <Halcyon> Like a drinking bar?
14:16:09 <Ampera> yes
14:16:16 <Halcyon> But you can't drink yet?
14:16:21 <Guest|71972> what is the bandwidth of a scope?
14:16:27 <Ampera> well when I do turn 18
14:16:27 <Guest|71972> dave needs to make a vidoe on that
14:16:37 <Halcyon> I thought the drinking age there is 21?
14:16:42 <Ampera> it is
14:16:43 <Halcyon> Guest|71972: It depends on the scope
14:16:55 <Ampera> thus when I turn 18, I'd have to drive 200 miles to drink at a bar
14:17:06 <Ampera> actually to be strict, we don't have a drinking age
14:17:12 <Ampera> we have a furnishing age.
14:17:22 <Halcyon> OK?
14:17:53 <Halcyon> Speaking of drinks, I might grab myself a wine, might help dull the pain of my shoulder
14:18:44 <Guest|71972> i mean what does bandwidth mean in regards to a scope
14:19:00 <Guest|71972> if im just looking at something that is DC does it matter?
14:19:16 * Halcyon calls for T3sl4
14:19:23 <T3sl4> buh
14:19:27 <Ampera> Bandwidth in general means a range of frequencies.
14:19:30 <Halcyon> Nerd questions :P
14:19:41 <Ampera> So a scope with a, let's say, 200mhz bandwidth can measure anything from 0 to 200Mhz
14:19:42 * T3sl4 plinks a MTG card at Halcyon
14:19:55 <coppice> Guest|71972: If you are looking at DC, why would you need a scope?
14:20:09 * Ampera calls T3sl4 a sexist pig and flips the table, like a true MTG player
14:20:10 <Guest|71972> rise times
14:20:32 <Guest|71972> measuring rise times of DV
14:20:34 <Guest|71972> DC
14:20:40 * T3sl4 bends over and holds a praying gesture beside Ampera's conspicuous fat buttcrack
14:20:41 <Guest|71972> and fall for that matter
14:20:41 <coppice> DC has no rise time
14:20:52 <Guest|71972> it most certainly does
14:20:56 <T3sl4> lul
14:20:59 <Ampera> if it did, then it wouldn't be DC
14:21:07 <T3sl4> you can have DC with an AC component that has rise time
14:21:14 <Guest|71972> ever heard of a step response
14:21:19 <T3sl4> that's what's meant by "pulsed DC"
14:21:27 <Guest|71972> the steady state result is DC but it has a rise time
14:21:31 <Halcyon> Jerry is nibbling on my face
14:21:39 * Ampera nibbles on Jerry
14:21:49 <T3sl4> the steady state result is 0 for t < 0 and 1 for t > 0, i wouldn't call that DC nor steady state
14:21:51 <Halcyon> No, Cockatiels are not for eating
14:22:03 <Ampera> Halcyon, why not
14:22:05 <T3sl4> Ampera likes to nibble cock
14:22:06 <T3sl4> atiels
14:22:10 <Halcyon> :P
14:22:20 * Ampera throws T3sl4 and has him stick
14:22:23 <Ampera> *to the wall
14:22:41 <Guest|71972> when you close a DC switch you get a DC voltage that does not oscillate but the action of closing the switch has a time it takes to do it
14:22:46 <Guest|71972> hence rise time and DC
14:22:49 <T3sl4> also, my inside joke on this subject, makes a reference to "squab on a stick" from Indiana Jones and the Fate of Atlantis
14:23:03 <T3sl4> what is "close a DC switch"
14:23:10 <T3sl4> if it's a DC switch, isn't it always on?
14:23:14 <T3sl4> or always off?
14:23:22 <Ampera> why not both?
14:23:32 * Ampera throws a poisoned cat at T3sl4
14:23:39 * T3sl4 sizzles Ampera with a half-opened, arcing switch
14:23:50 <Ampera> huh, surprisingly I no longer want cock
14:23:57 * T3sl4 poisons Ampera in the park
14:24:06 <T3sl4> which is also a moderately topical reference
14:24:15 <T3sl4> https://www.youtube.com/watch?v=yhuMLpdnOjY
14:25:51 <Ampera> https://www.youtube.com/watch?v=Obdv1jghXAE
14:26:02 <Ampera> Halcyon, https://www.youtube.com/watch?v=U4zA0xnBEJU
14:26:16 <Halcyon> Good song
14:26:38 <Ampera> of course it is, it's new wave ∴ good
14:27:36 * T3sl4 serves Ampera a little https://i.imgur.com/A2Eoac6.jpg
14:27:55 <Ampera> No, I have turned over a new leaf, I only want tacos now.
14:28:03 <coppice> T3sl4: DC is a vague term. It both means not crossing zero, and not consuming bandwidth. We really need separate terms for these things
14:28:57 <T3sl4> yep
14:29:16 <Ampera> weirdly enough I'm reaching a point where I'm beginning to understand what the fuck you two are even on about
14:31:47 * T3sl4 differentiates Ampera
14:33:21 <coppice> Guest|71972: try looking at the specs for scopes. Associated with their bandwidth they show the risetime that translates to. That is the fastest signal risetime they can follow
