02:56:21 <Guest|1775> Is the HP 54502A scope any good?
03:41:42 <Agripa> second, need to look it up
03:46:45 <Agripa> There is nothing wrong with it.
03:48:34 <Agripa> real time sample rate 400MS/sec ETS sample rate 20GS/sec
03:48:51 <Agripa> So plenty for 100MHz and 400MHz operation
03:49:39 <Agripa> Oh, wait
03:50:24 <Agripa> No peak detection. So no, I wouldn't recommend it.

04:15:35 <coppice_> Guest|1775: Is the CRT in good shape? I've seen some very badly burned ones
04:16:01 <coppice_> Agripa: why do you find peak detection so important
04:16:51 <Ampera> coppice_, I find peaks quite important, big and round peaks, I love em.
04:18:11 <coppice_> summit's wrong with your notion of a peak if something rounded counts
04:58:02 <Agripa> coppice_, because it maintains the maximum sample rate under all conditions preventing aliasing.
04:58:25 <Agripa> That HP supports envelope detection like any DSO should but not peak detection which happens during decimation.
04:59:16 <Agripa> I don't consider a DSO usuable in a general sense unless it supports peak detection. That makes the oldest good DSO the Tektronix 2230 which as far as I know, was the first to support peak detection.
04:59:47 <Agripa> Note however that DPO style oscilloscopes don't need peak detection because they have something even better.
05:00:28 <Agripa> peak detection is DPO operation with the minimum hystogram depth.
05:01:01 <Agripa> Hp had some peak detecting DSOs in that series but not that specific one.
05:03:19 <Agripa> The 546xx series had peak detection
05:04:14 <Agripa> So I'd recommend any 546xx series but not any 545xx series

07:59:16 <Agripa> coppice_, there is a reason most DSOs support peak detection or its equivalent. That view is from experience.
07:59:39 <Agripa> You can simply do things with peak detection which cannot be done without it and it saves a lot of time and user frustration.
07:59:58 <coppice_> Agripa: you seem to have a very narrow view of what someone would expect of an oscilloscope
08:01:40 <Agripa> coppice_, and consider the extend that Rigol lies and continues to lie in their documentation and marketting about which of their DSOs support peak detection. They consider it important enough to deceive their customers into thinking that their products support it when they do not.
08:02:05 <rust_collector> I am thinking about buying oe of those tiny dso-shell things. I do not expect much from it at all, lol

13:17:22 <Agripa> OK, why do people like Chick-fil-A? They basically have chicken paddy burgers and no greens or mashed potatoes like KFC or Lee's.
13:18:00 <T3sl4> it's a cromulent sandwich/tenders, so what
13:18:10 <T3sl4> why do ppl like mcd's? BK?
13:18:50 <Agripa> Yea, but I like hamburgers. I just don't see why people like Chick-fil-A in place of KFC or Lee's
13:23:09 <coppice_> Agripa: do people like Chick-fil-A, or is it just value for money, or in the right place at the right time?
13:25:47 <Agripa> Damnifiknow. That's why I asked.
13:26:14 <Agripa> Apparently the chicken breading has crack in it based on the answers I am getting.
13:27:56 <T3sl4> otherwise known as garlic powder, yes
13:28:58 <coppice_> if there's craic the Irish will go for it
13:30:46 <Agripa> I'd prefer KFC or Lee's but a Chick-Fil-A moved in at the local strip mall and is a lot closer.
13:32:21 <coppice_> so, you're tempted by the right place at the right time?
13:33:30 <Agripa> Oh, I like chicken. But I am dubious since there is a Wendy's and Hardy's there also.
13:36:14 <Agripa> The only place closer to me is Taco Bell and that gets boring after a while. I'd prefer Arby's but that is a long way from me.
13:41:03 <coppice_> Have you consider a little more diversity, like fish, or Asian cuisine?
13:41:45 <coppice_> or combine then, and have sashimi
13:43:23 <Agripa> I'm not interested in sushi. The only fish around here is fried. And there are no Cantonese places close unless I want Panda Express.
13:43:48 <coppice_> or, even if you want Panda Express

19:19:53 <Halcyon> Meow
20:10:30 * Halcyon nibbles on Ampera
20:10:32 <Halcyon> Mmm salty
20:10:52 <Halcyon> and a little chewy
20:33:22 <Ampera> hi Halcyon
20:33:46 <Halcyon> How's it going?
20:36:24 <Ampera> uhhh
20:36:36 <Ampera> great grandmother died
20:39:00 <Halcyon> Oh shit, I'm sorry mate :( *hugs*
20:39:14 <Ampera> ew gay
20:39:22 <Ampera> nah she was 91, would have been 92 this month.
20:39:39 <Ampera> She died effectively of late stage dimentia, but I don't know what the final cause of death was.
20:39:44 <Halcyon> Good life
20:40:16 <Ampera> I got a domain
20:40:19 <Halcyon> I guess people do die of old age
20:40:24 <Halcyon> Oh yeh?
20:40:51 <Ampera> currently just redirects to my dad's soccer club site, since I need to do some sort of web routing
20:40:59 <Halcyon> Fair enoug
20:41:00 <Halcyon> h
20:41:09 <Ampera> looking at using a reverse proxy to push traffic to different servers
20:41:24 <Halcyon> How do you mean?
20:41:29 <Ampera> I've found one I can integrate into pfSense, so I don't even need another machine, or worry about reliability.
20:41:55 <Halcyon> Can you not just add an A record for each server?
20:42:15 <Ampera> I've seen that some reverse proxy applications have the ability to determine what domain a request was resolved from, and route the traffic appropriately.
20:42:23 <Ampera> Not if each server is on the same IP
20:42:43 <Halcyon> Sure
20:42:58 <Halcyon> But you can just add the relevant port number to the URL?
20:43:24 <Ampera> so now everyone who wants to visit my website, first visits my dad, and then realize I told them to stick a strange :4263 on the end of it
20:43:27 <Ampera> that sure sounds practical
20:43:53 <Halcyon> If you're hosting a website on port 80, by default a browser will go to that
20:43:58 <Ampera> so instead of amperaa.net, it's amperaa.net:4263, don't forget the 4263 otherwise you get a soccer club
20:44:11 <Halcyon> But if you want someone to connect to FTP, you'd route the port number through your router to your FTP
20:44:13 <Ampera> Yes, but I have two webservers on one IP.
20:44:17 <Ampera> Both on ports 80/8080
20:44:19 <Halcyon> Ahh
20:44:25 <Halcyon> Well yes, then that gets more complicated
20:44:49 <Ampera> That's why I wish to use a reverse proxy to route all requests to different servers based on what domain it originated from.
20:44:55 <Halcyon> *nod*
20:45:06 <Halcyon> I didn't realise your dad was hosting at home as well
20:45:13 <Ampera> I just told you he was.
20:45:29 <Ampera> amperaa.net is the domain if you want to look at a German football club at all
20:45:45 <Halcyon> You said it redirects to your dad's page
20:45:48 <Halcyon> That could be anywhere
20:46:06 <Ampera> The A record goes to my IP.
20:46:11 <Halcyon> Anyway, I need to go make dinner, I'll be back soon
20:46:16 <Ampera> On port 80 and 8080 of my IP is that website
20:46:19 <Halcyon> Making steak sammiches
20:46:25 <Ampera> Nice.
21:32:39 <Halcyon> Mmm nummy meats
21:55:22 <K> hello
22:11:01 <Halcyon> Hey K
22:12:12 <steve30> morning
22:15:32 <steve30> I need to pop out to the shop and buy some coffee
22:19:01 <Halcyon> Morning Steve :) I'm off to bed shortly
