2023-10-14 02:18:43 https://www.youtube.com/watch?v=-5wpm-gesOY 2023-10-14 02:18:48 That's classic... 2023-10-14 02:19:45 Some interesting history too. It's a wild wild world we live in... 2023-10-14 13:48:25 Well, just poked a hole in a piece of aluminum foil with a toothpick and used it to project a sun image on the patio. Can definitely see a "bite" taken out of it. 2023-10-14 13:48:43 I was busy earlier during the best part of it, but we got to see at least a little of it. 2023-10-14 13:54:52 clouds, clouds, clouds, and more clouds. also maybe too far north. but, clouds 2023-10-14 15:57:35 Bummer. I hate it when that happens. 2023-10-14 15:58:05 oh, solar eclipse? 2023-10-14 15:58:09 pacific northwest probably isn't ideal for stargazing 2023-10-14 15:58:40 beautifully clear here right now 2023-10-14 15:58:47 of course it's 9pm so it's pitch dark, but still 2023-10-14 15:58:51 So, a night or two ago I was out walking with my wife and noticed that considerably more stars were visible than is usual for the Houston area. We bantered about possible explanations, but I think I realized yesterday what was going on. It's been drier than usual - humidity down nearly 10 points from the norm. I suspect just getting some of the water vapor out of the air is what let the light come through 2023-10-14 15:58:53 better. 2023-10-14 15:59:01 I think it's over now, but I don't know for sure. 2023-10-14 15:59:42 But yes, a annular solar eclipse cut a swath down from the northwest US, through Texas and on down through Mexico's Yucatan peninsula. 2023-10-14 16:00:16 We were slightly off to the side - only got 80% coverage here. The main line passed south of us. 2023-10-14 16:00:27 yup 2023-10-14 16:00:37 So I didn't get to see "the diamond ring" effect. 2023-10-14 16:00:45 we're a bit too far north to really get much of a shot at total solar eclipses 2023-10-14 16:00:46 so less light blooming due to less vapour? 2023-10-14 16:00:47 Just a little sun disk with a crescent cut into it. 2023-10-14 16:00:57 Yes, something like that. 2023-10-14 16:01:18 It's not like the stars were "popping" or anything, but normally here you see only a meager few. 2023-10-14 16:01:38 It's sad that we've deprived ourselves of the sky our ancestors took for granted. 2023-10-14 16:01:55 It takes a major effort now to get to see a first-rate nighttime sky. 2023-10-14 16:02:10 the 2015 eclipse was good, roughly 75% of the Sun obscured 2023-10-14 16:02:26 We had a total eclipse here a few years ago. 2023-10-14 16:02:32 I got a really good look at that one. 2023-10-14 16:02:35 it was actually better further north but I got a good view of it even down south at 56° 2023-10-14 16:02:58 Do you live in the southern hemisphere? 2023-10-14 16:03:11 no, why? 2023-10-14 16:03:26 "down south at 56." 2023-10-14 16:03:35 I think of 56 as quite far north. 2023-10-14 16:03:36 yeah, I live in Scotland 2023-10-14 16:03:48 I see. I thought that was what I remembered. 2023-10-14 16:04:02 I live at like 29 degrees 40 minutes or something like that. 2023-10-14 16:04:05 from where I'm sitting, England is roughly twice as far as space 2023-10-14 16:04:16 maybe 1.75x as far 2023-10-14 16:04:30 What are you calling space? A hundred miles? 2023-10-14 16:04:45 250 2023-10-14 16:04:52 basically the orbit of the ISS 2023-10-14 16:04:52 miles or km? 2023-10-14 16:04:55 miles 2023-10-14 16:05:06 Ok. That's about how far I am from San Antonio. 2023-10-14 16:05:07 that'd be about 400km 2023-10-14 16:05:07 nautical or statutary? 2023-10-14 16:05:17 Austin's a little over half that. 2023-10-14 16:05:21 laden or unladen? 2023-10-14 16:06:26 I actually moved a couple of hour's drive north, because I got pissed off with having to drive to England 2023-10-14 16:06:59 What did you have to go for? 2023-10-14 16:07:05 I fix fire stations 2023-10-14 16:07:08 basically 2023-10-14 16:07:25 I work for the fire brigade, in the "How The Fuck Did You Manage To...?" department 2023-10-14 16:07:36 :-) 2023-10-14 16:07:48 oh, do tell stories 2023-10-14 16:08:16 when I lived a little north of Glasgow I kept getting sent to places like Langholm, for which I had to drive like 20 miles into Cumbria to turn round and drive back up again 2023-10-14 16:08:34 or, drive about 30-40 miles over single-track roads at about 25mph 2023-10-14 16:09:17 paved or just barely bitmuned? 2023-10-14 16:09:27 paved, but a lot of slow traffic 2023-10-14 16:09:31 lots of tourists 2023-10-14 16:09:54 frenchmen with baggos in tow? 2023-10-14 16:09:54 Zarutian_iPad: people underestimate how long it takes to get around Scotland, it's hilarious 2023-10-14 16:10:37 I should know, I live in Iceland and it always supprises tourists how distant things are 2023-10-14 16:10:48 ... and getting more distant over time! 2023-10-14 16:10:51 I had to explain to my mate's girlfriend who was over from the US - she's a logistics person for the US Navy and has a fair grasp of geography - that you can't really fly into Prestwick airport, drive up to Inverness, then drive over to Skye, and then back to Glasgow in one day 2023-10-14 16:11:05 Zarutian_iPad: I expect you have the same problem 2023-10-14 16:11:20 Zarutian_iPad: yes it's only <-------> that on the map, but that's a two hour drive 2023-10-14 16:11:35 also I hope you know how to *really* drive off road 2023-10-14 16:12:11 we get a lot of tourists from the US who see that it's about 300 miles from Edinburgh to Skye, so they think they can get there, see Skye, and get back the same day 2023-10-14 16:12:37 that'd be cracking on for 12 hours of driving for me, and that would *not* be sticking to any speed limits 2023-10-14 16:13:06 naah, we do not drive off road but there have been so many times that tourists in rentals have beentraffic impediments that it is now part of the mandatory video for rental customers to watch 2023-10-14 16:16:04 Zarutian_iPad: so we have single-track roads the width of one car, with "passing places" about big enough for one car 2023-10-14 16:16:20 Zarutian_iPad: if you've got a passing place coming up on your right - we drive on the left - you stay left 2023-10-14 16:16:37 yebb driven those, even a bridge and tunnel version 2023-10-14 16:16:42 Zarutian_iPad: it's amazing how many people dive right, and run into the car going to the left 2023-10-14 16:21:24 I've noticed on the drive up to Scotland there's stretches where the average speed limit is a solid 10mph over the legal limit 2023-10-14 16:21:39 veltas: yes 2023-10-14 16:21:54 veltas: also, if you're coming up this way and you're on the M74, sack that shit 2023-10-14 16:22:08 get onto the "old A74", from about Gretna up to damn near Hamilton 2023-10-14 16:22:10 And there's no speed cameras because they don't hate their people enough to make them drive that road at the speed limit 2023-10-14 16:22:16 you'll be about the only car on the road 2023-10-14 16:22:52 when I'm driving down to Bradford I stick to A roads as much as possible 2023-10-14 16:23:54 When I started at my job I would always drive down the M1, now I have to drive down the A5 because they've just continuously made it worse to drive on the motorway 2023-10-14 16:24:07 the M1 is a shitshow 2023-10-14 16:24:21 There used to be a hard shoulder and then they did works for years to remove that and make it a "smart motorway", which didn't improve congestion but made it more dangerous 2023-10-14 16:24:54 I went down it a few years ago to go to Infest because we were sitting in traffic for the M74 Raith Interchange, and my mate Malc said "oh hey there's a post in scotgoth saying that two of the Edinburgh folk are stuck because their lift has flaked on them" 2023-10-14 16:24:57 Currently they're 'upgrading' a roundabout at my junction and it's made it just painful, always traffic, so I've been avoiding that junction for months 2023-10-14 16:24:58 say no mre 2023-10-14 16:24:59 *more 2023-10-14 16:25:02 we have two spare seats 2023-10-14 16:25:03 we're on it 2023-10-14 16:25:08 fuuuuuuck meeeeeeee 2023-10-14 16:25:18 the A1M and M1 were a blasted blighted hellscape 2023-10-14 16:25:35 Nice 2023-10-14 16:25:36 and, now they've completed it, it's orders of magnitude worse somehow 2023-10-14 16:26:22 I've noticed there's constant work around here upgrading roads that don't need touching and creating traffic 2023-10-14 16:26:31 It's just job creation 2023-10-14 16:26:37 about six months ago I drove from just outside Edinburgh, over to a bit south of Glasgow, picked up a bootload of crap, drove down the M74 and back across the A69 2023-10-14 16:27:00 and *still* beat someone leaving from Edinburgh to the Scotch Corner services 2023-10-14 16:27:12 how is this possible 2023-10-14 16:27:12 how 2023-10-14 16:28:29 Yeah I've done both routes and preferred M6 / M74 route 2023-10-14 16:29:46 Also on A1 where there's a single lane people were driving quite mad, went over a hill crest at one point to an oncoming vehicle overtaking someone, had to emergency stop for them 2023-10-14 16:32:35 one thing I have always hated regarding folks driving is the tendency of some to 'plug' the only lane in that direction by driving min distance from another car 2023-10-14 16:33:08 making it so that one has to overtake both cars 2023-10-14 16:33:19 which is often unsafe 2023-10-14 16:34:31 I do an awful lot of driving and at this point I wish people would just be more patient 2023-10-14 16:35:47 Some days people's impatience drives me mad, it's not worth trying to save a minute by doing something dangerous to me or you 2023-10-14 16:36:41 Yeah, sometimes around here it feels like taking your life into your hands going out at rush hour. 2023-10-14 16:36:48 I avoid it if at all possible. 2023-10-14 16:36:53 As for people driving fast, I don't care, I let people overtake me easily if they want to drive faster than me. 2023-10-14 16:36:59 You do you etc 2023-10-14 16:37:57 My main peeve is when people plug the passing lane and just hover by the car they're next to, or take 2-3 minutes to ease their way by. 2023-10-14 16:38:03 It's just rude. 2023-10-14 16:39:04 Yeah either them ... or the car they're overtaking if they're just speeding up while being overtaken 2023-10-14 16:39:35 or the "hobby" of many of staying in your blindspot instead of going a bit forward or back 2023-10-14 16:40:45 There's a lot of weird psychology to driving 2023-10-14 16:40:52 Oh yeah. 2023-10-14 16:41:22 People will behave in ways behind the wheel they'd never consider "face to face." 2023-10-14 16:42:13 Almost like the internet (people will say things online they'd never say in person), except driving isn't *quite* as "anonymous" as the internet is. 2023-10-14 16:43:39 you mean like Penny Arcades greater fuckwad theory? anonymity + "normal person" + audience = great fuckwad 2023-10-14 16:44:34 turns out you only need the last two 2023-10-14 16:44:39 Yes. A) people know you can't reach them, so their "ugly" can be completely uninhibited, and B) people LOVE to operate in front of an audience. 2023-10-14 16:45:29 And 99% of them have a severe case of "I WILL have the last word." 2023-10-14 16:46:02 And they're not willing to just "disagree" - they want you to publically bow down and acknowledge their greater wisdeom and knowledge. 2023-10-14 16:46:14 I'm just not very good at bowing down. 2023-10-14 16:46:52 I think my first wife beat that all out of me. I remember leaving that situation with a very strong "never again" mentality. 2023-10-14 16:47:49 one line I heard a manager respond to a Karen saying she will tell her friends how awful the place is: if your friends are like you the please do as we do not want any of your kind of tantrum attitude 2023-10-14 16:48:04 :-) 2023-10-14 16:50:05 Yeah I have learned you need to never apologise insincerely 2023-10-14 16:51:44 I always try to tell the truth for spritual reasons, but there are some people who are strongly antagonistic towards the truth or honesty 2023-10-14 16:52:29 I really pissed a nurse off once because she was following up on me after a surgery, they told me to do some stuff to treat the wound and I didn't do it 2023-10-14 16:52:43 And when she asked if I had I told her no and she thought I was saying that to be rude or aggressive 2023-10-14 16:53:16 And I was just being honest, I couldn't be bothered or forgot or something, not trying to upset her 2023-10-14 16:53:33 I think she's used to people just lying and saying they do everything they're told when she phones up 2023-10-14 16:54:08 so she can tick her boxes and go back to whatever she was doing 2023-10-14 16:55:08 I'd never thought of that, but it's a plausible idea - that what people really want to here is whatever is "normal" so they don't have to deviate from their standard program. 2023-10-14 16:56:48 I call those crankspinners 2023-10-14 16:57:16 as they might as well just be spinning a crank 2023-10-14 17:05:11 I see folks kind of like that at work. There are always "go getters" who always try to get positive attention from the higher up folk, but this category I'm talking about right now just wants to find a little crevice somewhere in the organization, snuggle into it, and attract as little attention as humanly possible. 2023-10-14 17:09:04 I think some organisations essentially create these people by failing to reward good work and so they just stop playing a game of skill and start farming 2023-10-14 17:09:49 Just water those plants 2023-10-14 17:10:12 one of my better bosses liked to give out tasks and just let us get on with it but asked to be let known if there was an problem 2023-10-14 17:15:56 Yes, I think that is often the case. 2023-10-14 17:16:46 The thing is, it feels to me like big organizations don't actually want people to "stand out." If someone is uniquely capable, then they're not replaceable as easily. 2023-10-14 17:17:07 They just want that crank Zarutian_iPad was talking about spun. 2023-10-14 17:17:31 I.e., they don't tend to create positions that encourage staanding out. 2023-10-14 17:19:29 I want to add a little mount platform to my telescope for my notebook, and a camera that will let me put the image on-screen. The scope has one of those "GoTo" motor control handsets - I'd like to move that control functionality into the computer as well. 2023-10-14 17:19:52 There are a number of software packages that will do that, and I already have one of them installed; it's called Stellarium. 2023-10-14 17:20:21 KipIngram: the hanset has a serial or usb port? 2023-10-14 17:22:09 Serial unfortunately. 2023-10-14 17:22:41 So I'd need some kind of little adapter for that. 2023-10-14 17:23:01 rs232 via db-9 connector I presume? 2023-10-14 17:27:11 No, the controller plugs in via a little phone-jack like thing. Except not really a phone jack - it's smaller. 2023-10-14 17:27:56 But I don't think there's anything in the telescope itself that is digital - I think all of the digital stuff is in the handset. I think it's just sending motor control signals to the main scope. 2023-10-14 17:28:07 oh, probably ttl via tip, ring, and sleave mini mini jack 2023-10-14 17:28:18 I think the handset is a self-contained computing unit. 2023-10-14 17:28:25 oh? 2023-10-14 17:28:32 I think. I don't know for sure. 2023-10-14 17:28:44 But I don't see anything else anywhere that looks electronic. 2023-10-14 17:29:07 how many contacts are on that connector? 2023-10-14 17:29:08 I'm sure I can find some documentation on it somewhere. 2023-10-14 17:29:17 Hang on I'll go see. 2023-10-14 17:33:51 Looks like 6. I think I found a manual for it here: 2023-10-14 17:33:52 https://inter-static.skywatcher.com/downloads/Synscan_V4_Hand_Control_Manual_SSHCV4-F-161208V1-EN.pdf 2023-10-14 17:34:21 Page 48 has pinouts of the two connectors - the second connector on my setup isn't hooked to anything. that is probably where they'd have you plug in a computer. 2023-10-14 17:34:37 I'm not sure i see why the handset is needed at all, though, if the computer has the right software on it. 2023-10-14 17:36:25 And it looks like there is electronics somewhere in the main scope - that manual seems to imply it. 2023-10-14 17:36:35 It says something about "motor controller firmware update." 2023-10-14 17:36:44 the Telescope Mount Port is on the mount itself? 2023-10-14 17:36:59 And there are Tx and Rx signals in that connector - they're talking to something. 2023-10-14 17:38:07 Actually the connector that's pluged into the mount looked to me like it had six conductors, not eight, so that matches the "Multi-purpose port" in the pin-outs. 2023-10-14 17:38:23 The other one is called "telescope mount port," though, so... I'm not sure. 2023-10-14 17:38:37 it was hard to count - I need to get it under a magnifier and in better light. 2023-10-14 17:39:41 Anyway, my preference is to dispense with the handset altogether and connect the computer directly to the telescope. 2023-10-14 17:40:37 But that may or may not be something supported with the commonly available software. 2023-10-14 17:40:51 I'll wind up having to do it whatever way they planned it. 2023-10-14 17:41:42 you could bus sniff it 2023-10-14 17:42:13 just to see what the protocol is 2023-10-14 17:50:00 Ok, it says in there that the multi-purpose port is an RS-232 connection intended for a PC. I counted conductors on the end of the cable that connects to the telescope - I should have counted at the other end. Checking on that now. 2023-10-14 17:52:02 Ok, makes more sense now. Eight pins on the other end - so that is the "telescope mount connection" just like you'd expect. The multi-purpose connector jack is sitting right there next to it. 2023-10-14 17:52:29 So, likely I can just establish an RS-232 connection through there to the PC and it will just work. 2023-10-14 17:52:42 It already says that it's meant to interoperate with popular planetarium programs. 2023-10-14 17:53:12 You can't do long-exposure astrophotoraphy with this because it's a Dob. 2023-10-14 17:53:40 Dob? 2023-10-14 17:53:46 It will track targets, but when you track with a Dob you turn both motors instead of just one and the field of view "spins" around the viewing axis. 2023-10-14 17:53:58 Dobsonian. Altitude/azimuth motions. 2023-10-14 17:54:01 Not equatorial. 2023-10-14 17:54:35 But just having the thing stay on target without me having to nudge it constantly would be great. 2023-10-14 17:55:03 It should be able to do that now, no PC required, but I've never managed to get it polar aligned well enough to make it work. 2023-10-14 17:55:10 Of course, I haven't tried that hard either. 2023-10-14 17:55:23 I've mostly used it as a fully manual Dobsonian. 2023-10-14 17:55:34 so having an extra motor to spin the optics the other way might be a hack 2023-10-14 17:55:52 Yes, but figuring out how to get that in there would be a trick. 2023-10-14 17:56:03 I'm more inclined, though, toward short exposures and stacking. 2023-10-14 17:59:05 Actually an idea I had once, which I'd have to do myself - I've not seen it off the shelf - would be to use a linear CCD instead of a 2D one, and just let Earth's rotation carry the image field across the CCD. 2023-10-14 17:59:30 Basically grab the image one strip at a time and glue them together in software. 2023-10-14 17:59:56 That way all your pixels would be along one axis, and it would be like having a much larger pixel count whole-image. 2023-10-14 18:00:01 like some earth observational satelites do 2023-10-14 18:00:15 Yeah, similar. 2023-10-14 18:11:22 But anyway, that's a digression. Looks like my options are to either get a serial adapter and plug into that other port, or upgrade my handheld to a newer USB model and connect that way. 2023-10-14 18:11:49 The latter approach probably puts me on a more well-maintained path. 2023-10-14 18:12:21 But would likely cost more. 2023-10-14 18:27:42 Wow. I emailed a company about one of their CCD cameras - I asked them if it could be expected to work with Linux. The guy already replied - and on a Saturday no less. And he included a link to a page re: using their products with Linux. That's great service. 2023-10-14 19:36:22 Ok, that guy's info included a link to their "studio" software - I snagged that and it installed and runs. So I guess I'll look at ordering a camera. Got my eye on a 20 Mpixel one. 2023-10-14 19:36:51 I need to study on it, but it looks like these are made to just go into the eyepiece holder. 2023-10-14 19:39:36 veltas: yes i did starting forth. did the gforth tutorial too. good stuff. 2023-10-14 19:46:37 Croran: You'll be an old hand in no time. I do think some aspects of it only come through practice, though - as you write some Forth code, you'll gradually evolve your own practices that work well for you. 2023-10-14 20:06:49 hey KipIngram 2023-10-14 20:07:11 Hiya. 2023-10-14 20:07:19 I was thinking about the collatz conjecture and making a piece of wall art 2023-10-14 20:07:40 ever consider some kind of decoration based on math? 2023-10-14 20:07:52 I mean something that does computations 2023-10-14 20:08:18 You mean something that is dynamic? 2023-10-14 20:09:01 Like you'd be able to somehow give it a starting number and watch it go? 2023-10-14 20:10:10 I think it's a neat idea - look forward to hearing the details. 2023-10-14 20:13:42 ya we need wall decorations and some of the wire are things look pretty neat 2023-10-14 20:13:52 Found a suitable looking notebook platform that I can just bolt onto the side of my scope. 2023-10-14 20:14:07 Sounds fun - I do actually like that kind of thing. 2023-10-14 20:14:14 whether the result went up or down doesnt seem that interesting to display though 2023-10-14 20:14:24 Great conversation starter, too. 2023-10-14 20:15:14 yep 2023-10-14 20:36:58 I thought about making a 7400 logic computer for that purpose 2023-10-14 22:31:54 Oh come on - that slacking. You should use pipes, valves, and water pressure. 2023-10-14 22:32:13 that's 2023-10-14 22:33:19 I've never actually comtemplated a project quite that far back - I did give pretty serious thought to using a fleet of 22v10's, though. 2023-10-14 22:33:46 I felt confident there wouldn't be any back doors in 22V10's.
