Anyone else feeling like we are starting to get a little clumsy without mods?
@Undo hey :) what do you mean?
our own mods, or SE mods not often enough here?
00:30
@Tildal Our own - it seems we aren't a full 'citizen' of the network yet.
@Undo I didn't really get the impression that we're being ignored, actually far from it, but I believe it was mentioned (by Anna Lear IIRC) that Robert wasn't available for some time, or something like that? Could be that's the reason for some "delays"?
But I didn't notice any pressing issues with the Q&A, and it's probably quite normal that we're still struggling a bit with our definition, it's just a young website... You had anything specific in mind?
@Tildal The request for Manish to merge one of the questions from Physics over to here, only to find we don't have mods to do it here, having to have the community team handle any moderation-y thing, etc. have been getting to me :)
Oh... I see, yes I remember that. And I have a few questions / suggestions for the next time one of the SE community mods will be around, but I'm in no hurry... if it won't happen this week, then I'll ask a new question on our meta or mSO
@TildalWave You rang? ;)
@JonEricson Oh, yes it appears so LOL... I'll let @Undo explain what he wanted 1st ;)
00:41
@Undo We're making our final evaluations. Emails will be sent soon.
@JonEricson Actually, you can probably multitask :) I have a few questions... 1st - is that @StackSpaceExp our "official" Twitter address?
2nd - Would it be too early to create a community ads post on meta, but - while in beta - limit it to promoting our own features better (Twitter page, Weekly Newsletter, Blog (??),...)?
@TildalWave We are inboarding several new hires ("Hi there!") and it's taking a little longer than normal to get tasks done. (Hopefully, the trade will be that future tasks will be a lot quicker. ;)
@JonEricson Sure, no problem... I'll let you unbox your rubber duckie :)
@TildalWave Yes.
@TildalWave Yes. Community ads are for graduated sites.
@Jon Ooo! New hires! Completely understood. Have to teach the new guys how to push the shiny buttons!
00:46
@Undo And more importantly, when not to!
@JonEricson Could we somehow else promote those features of ours that I mentioned on the main page / other pages?
@TildalWave Sure. You could try one of the graduated sites. Physics, perhaps?
@JonEricson That's why it's important to have "bring your kids to work" days!
Heh. Or invite cub scouts to tour the facility.
@Jon Invite Girl Scouts to come re-theme all the sites. Then you can teach your new hires how to undo things!

Q: Community Promotion Ads - 2013

Grace NoteAs it is December 2012, we are now going to reset our Community Promotion Ads for the new year. What are Community Promotion Ads? Community Promotion Ads are community-vetted advertisements that will show up on the main site, in the right sidebar. The purpose of this question is the vetting pro...

@Undo with your nickname in mind .... this sounded a bit weird :)) :P
:) I sometimes wonder how many people think it's a button.
hahaha
@Undo well you have 74 profile views, I have 16
True. I'm up to 500-some on SO, I think.
@JonEricson Cheers! Tho, I guess, that'd only serve to promote Space Exploration (if upvoted enough)... how about our newsletter and twitter page? Should I just post some meta question as a reminder to all, that we do have them?
00:53
@Tildal We have a twitter thing?
@Undo @StackSpaceExp
@TildalWave Sure. That's a fine idea.
@JonEricson Right, thanks! It might take me a few hours, I'm a bit busy shooting shooting stars :))
Don't forget to look up the skies tonight and make a wish ;)
But external participation is going to be more important. Short of inviting rocket scientists to answer some questions, asking questions for Google to discover (and making sure they get answered somehow) is probably the best thing y'all can do.
@Tildale What's special about tonight?
00:56
@TildalWave Damned light pollution.
@Tildal Typing on mobile. What's happening tonight? Meteor shower?
@JonEricson meh, just look up for 2 minutes, assume at least one of the Perseid meteors burnt in the upper atmosphere and make a wish anyway... half of the stuff I get with my cam are moths and airplanes also LOL
@Undo it's the annual Perseid peak tonight
Ahh... Need to find question to ask about it!
meh, that's astronomy,... and neck stretching
@Tildal I think I have something...
01:01
right... it's 3am and by my calculations, it should now be the most frequent for my part of the woods... see you in a while ;)
Could be a network hit, methinks:

Q: Does the Perseid peak affect launches of space missions?

UndoTonight (Aug 12 2013) is the annual peak of the Perseid meteor shower. Since meteors are chunks of rock flying through the atmosphere at crazy high speeds, I'm wondering if there are any considerations for the launching of space flights on and around this time, as it is generally detrimental to...

@JonEricson This might be a terrible thing to ask, but I'm working on an iOS SE app and was wondering if anyone at SE would like to help test it - I completely understand if no one wants to, but just wanted to throw that out there...
@Undo Do you know about the StackApps site?
@JonEricson Yep, but I'm not getting much traffic there.

01:16
@Undo Cool. I'll take a look when I have time. (It's about suppertime for me.)
@JonEricson No problem. Have a nice supper!
Thanks. ;)

Q: Can you please find a different reason to close this question?

Major StackingsPlease, if the question needs to be (down voted and) closed, can you find a valid reason for closure as this is not a duplicate question? One asks for the mass launched into Space. My question asks how much mass was required to make those launchs possible. Granted, it may not be the best question...

 
2 hours later…
03:19
@Undo I went to write the answer and was beaten to it... posted anyway, maybe you find some additional info welcome. If not... tough luck :P :))
@tildal Lol. Additional info always wins. Unless it's wrong :p
If it's not a duplicate, it should be corrected. just pretending we closed it as too broad is not okay
the best course of action would be to flag it, not to ignore it
03:37
@JohnB Yes - I'm wondering how this duplicating slipped through the cracks.
Going back to what Grace said here: if it's broad and put on hold but never improved, it should eventually be deleted
I don't think duplicates are meant to be deleted
04:01
@JohnB Me neither ... they add some value to making answers easier to find, and is essentially two differently worded questions pointing to same, or sometimes even a few more answers.
@JohnB There was a lot of confusion with that question, and dare I say OP didn't get up on the right side of the bed that day either... or I was completely misunderstood for some other reasons, whichever the case. But it was later edited by others to read almost exactly as the one it's marked a duplicate of, so in that narrow frame of time, the close votes were possibly spot on.
@TildalWave gotcha
and I apologize for reading your name as TidalWave all along
@JohnB I tried suggesting on mSO that we should get a chance to review our close vote reasons even before the questions are closed (but edited in the meantime), but I obviously wasn't heard :(
I honestly hope the second point will only be a factor on the same revision. If the post was edited in the meantime, that really shouldn't prevent you from acting according to it's new contents. Some Stack Exchange websites don't have as many reviewers for this not to cause a problem or needlessly add to their respective moderators' workload. — TildalWave Jun 11 at 14:55
That was before the new changes to review system were in effect. And I still think it would make sense... someone also commented that we should be notified if the post was in the meantime edited, so we could review our own votes, which is also a good suggestion IMO
Maybe with new updates, huh? :))
it's a complicated thing to think about
or maybe that's because it's past midnight for me, which I just realized o_o
where'd the night go!
04:17
@JohnB It's a bright daylight here, and the Sun is nearly up
@JohnB I actually did the same thing until just now. Obviously I haven't really been paying attention.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
half of my net fell down... you think one of the Perseids hit some satellite? :))
04:41
Thinking of which, that could be a question - How often has it occurred that a meteor hit an orbiting satellite, space station or a laboratory, and what are estimates such can happen for satellites in LEO, GSO,... Would anyone care to ask it, if you think it's any good? I'm off to bed so you can all breathe a little bit easier without me hijacking the chat with my tosh :)
 
3 hours later…
07:43
@TildalWave agreed
@TildalWave hmm, me and you make up 40% of this chat rooms posts, we need to encourage more people to come here and discuss spacey things!
@RhysW ssshhhh I'm supposed to be sleeping! You blew my cover!
08:04
@TildalWave what the, i was leaving messages for you for when you got back, go back to sleep! :P
08:17
@RhysW I'm trying to help out guys in the DMZ with that user ramjet... talking in Belarus now LOL, I think he's now appreciating what we were trying to say better., but I do hope my translations make a bit more sense than his English
@TildalWave ahh, did you get your long exposure shots of the meteors btw?
@RhysW No luck, only moths, bats and airplanes :( I didn't have a good position either, and I wasn't bothered to place the tripod outside. The Perseids were coming from close to zenith, and I couldn't get a clear view of the whole sky. But frankly, I didn't see that many either, I think it was a bit too early and Americans will get the best shots
@TildalWave ahh thats a shame, would have made a nice gravatar for you for a while :P
ooh tha launch times have been updated
looks like we are waiting a fortnight from today for the next one, a launch of a Delta 4 Heavy NROL-65
oh no, one on the 19th, it just wasnt shown for some reason
08:36
afternoon
lull room
@RhysW yup the ISRO one with the troubled cryo upper stage is on 19th
@DarkHorse Afternoon! Wait... afternoon? You're from OZ?
where is OZ?
It's 16:38 at PM
in my time zone
@TildalWave
@DarkHorse Oh, sorry... I thought it's earlier here too :) I really need to go to bed LOL (and OZ = Aussieland = Australia = Down under)
@DarkHorse Singapore?
China
good night @TildalWave
@DarkHorse I was close :) Good night!
08:44
bye
well... close... China is so big, anything seems close when you need to zoom out so much :)) anyway, take care all!
@TildalWave cya wave :P

Tell you what, last night was awesome for shooting stars. We sat out with all the kids and neighbours until midnight. Saw an incredible number of shooting stars, the ISS and eight satellites (think two were Iridium)
ooh very nice!
The view from my friends house here on the north downs is incredible
Last night we sat out on the grass. The night before we watched from the hot tub, which wasnice
But less meteors the night before

15:16
@Tildal How's the view from that 2k mark?
15:26
Surely you can answer that @Undo :-)
@Rory Now I can. I can see little 1.999k users running around trying to get repz!
And a little brown circle telling me to go review my own suggested edits :P
15:46
Heh. The hazard of me going on a camping holiday - very difficult to post so you guys are miles ahead of me in Rep now
16:03
@Rory You could catch up to us with one rep capped day...

Q: Migrated question lost CW status

Q: Can we make "space-sickness" and "motion-sickness" tags as synonyms?

TildalWaveWe have two tags, space-sickness and motion-sickness on the main site, in the context of Space Exploration both describing same range of symptoms known as space adaptation syndrome a.k.a. space motion sickness. Any objections to making these two tag synonyms? I felt I had to reject one suggested...

@TildalWave Nice catch on those two tags.
I saw that suggested edit, and skipped it.

Q: Is the 'microgravity food safety' question on-topic?

Happy Enthusiast Badge Day to all..(250 mins from now)
@trapo Only on Meta for me :(
I will not attend the party, however..need to sleep..
@trapo Good luck with that endeavor!
@Undo: did u miss some day?
@trapo One day, somehow only on main.
19:54
Ouch..
I know... Just 13 more days, though. I'll get my Meta badge today, though:
One day I got fever and I forgot to visit SO.. I've lost 42 days :-(
Now visit SO is first thing I do every morning after stopping the wake up ring :-)
@trapo I've got Fanatic on SO :)
I think I need at least 6 ISS revolutions of sleep ;-)
@trapo Wow - how long's it been?
20:00
@Undo: 92 mins X revolution ;-)
So nine-and-a-half hours. Still a lot.
I wonder if each of these last the same amount of time
@trapo What's your stance here?
It's what I need :-)

20:07
Since English is not my native tongue, space–sickness is more intuitive to me
Motion–sickness recalls me something car related..
@trapo I'm thinking the same way.
Are u from US?
Yep :)
@trapo Hubble time is allocated in orbits.
@Donald.McLean Really? Didn't know that. Could you get a half-orbit?
20:13
@Undo Same as yours :P Congrats!
@TildalWave Ehh?
What's the same?

@Undo the view from the 2k mark ;)
@TildalWave Ahh, yes. It's fun watching the little people run around like ants, no?
Wonder what the view is like from Pearson's perspective :P
20:15
@Undo you'd like them believe that, no? :))
@Undo Probably not. Most targets you have to worry about occlusion by the Earth.
@Donald.McLean Ahh - if only the earth wasn't there...
That's why the Deep Field is just about straight north and the Ultra Deep Field is just about straight south.
The "continuous viewing" zones.
That makes sense.
@Donald.McLean: need at least 6 ISS orbits then, thak you for spotting the error.
20:29
@trapo We knew what you meant.

21:34
I like that the site looks much more alive today :) You're all pushing those share buttons, right? :P
@ManishEarth Is it possible to include in chat room feeds a twitter page? I think that'd make feed management a lot simpler, at least for stuff on twitter.
I.e. make a new twitter account, follow with it anything of interest here, add it to the room feeds
@TildalWave Does Twitter provide RSS/Atom?
@TildalWave Sure
Oh you mean the posts followed by a user
dunno
@ManishEarth Dunno, I'm not often there TBH... I use widgets :P
@ManishEarth No no... I mean one of the room owners (@RhysW in our case) creates a new Twitter account, then add its RSS/Atom feed to the feeds here, and use the Twitter account to add future feeds instead (by simply "following" other feeds)
@TildalWave you rang?
@TildalWave I think there are sites that post feeds to your twitter if that's what you're asking
@RhysW yes m'lord :)
21:42
he means make a twitter account, make the twitter posts come to this room, then use the account to 'follow' feeds of interest
Well, can you follow feeds like that in Twitter?
yeah i think so
Two parts to this: Figure out how to get an RSS feed for a given twitter handle, and figure out how to pipe feeds to a twitter account. They seem doable. I can't say how to do them though :P
@ManishEarth hmmm no. I meant to manage feeds in our chatroom easier... some feeds we have don't make much sense, as we get updates for February next year, and are not reminded of upcoming stuff... I thought that by reusing Twitter feeds instead, this could be made simpler?
oh... this has already been addressed, sorry I was distracted by my cat LOL
@TildalWave Yeah, so basically you want to pipe feeds to a twitter bot-thing, and then add that to feeds here, right?
FWIW there probably are ways of simply aggregating feeds
21:45
@ManishEarth yup... if that makes sense, of course
@ManishEarth but they come in here as they are posted in feeds... which is sometimes completely off with their dates of events... I thought if we use twitter following instead, feeds might be more time relevant?
of course, we'd need to make sure that it wouldn't needlessly spam our chat room, so only follow highly relevant targets
@TildalWave As in?
O_0
@ManishEarth That worldwide launch schedule, for example... the feed was updated to include launch in February next year just a few minutes ago, but we didn't get any update on the launch that's due in next week, short of having it fed to us "en gross" when @RhysW added the feed
@TildalWave Oh, that's because adding feeds on chat is strange
21:50
i plan to check it daily myself
That won't be an issue if you use an RSS aggregator
@ManishEarth Would adding feeds from twitter accounts be better at this?
Ohhh, I see what you want
i dont have time to do one
@TildalWave Maybe
@TildalWave So use an RSS aggregator on twitter feeds. It's hard to get your account to retweet everything it follows
21:51
@ManishEarth Your take - worth a try? I don't wanna employ @RhysW for nothing, sending beer to England isn't cheap LOL
@TildalWave I'm confused as to what you want to do :P
@ManishEarth what's the time in your parts of the woods? :P
3:21 AM
ouchies
joking, it's probably me not explaining it good enough, I'm being chased by my cat LOL
21:54
I'm waiting for mathematica to spit something out :P
it's the feline hunting hour
I gave it some progress bars and its going sloooowly
@ManishEarth because of UI refreshes?
lol no
@TildalWave Probably because it's just big.
He's making the final calculations for taking over the world - it's not simple, ya know...
21:55
I've given it 1000*100 calculations to do, where each one involves the evaluation of this function
@ManishEarth i know the answer
@Undo oh :( there goes the neighborhood
...i hate you, stole my joke xD
21:56
Sorry, the answer needs to be a 1000x100 table
And each element can't be 42 :P
@ManishEarth of 42's
42 42 42 42 42 42 42 42 42
damn
because the graph would be uninteresting
xD
if i was dedicated enough i woul dget the numbers needed to make the graph the shape of a 42
"What do you get if you multiply six by nine?"
21:58
54?
42.
no undo, just no :P
:D
At least we're not too off-topic today...
spaaaace
ahaha
its not new :P
OK, then it's not new.
There, it worked.
22:02
i need to petition to get room owners more powers :P
who wants to sign it? :D
this is a trap, right?
@RhysW Uhhh.... If I was room owner, sure. But the government doesn't need more power :P
no but i do :P
@TildalWave Of course not. The petition is on the other side of this patch of ground with leaves over it.
22:03
@TildalWave only if you dont sign it :P
@RhysW Governm... urrr... appointed leaders
@RhysW here ya go:
Happy?
@ManishEarth yes :)
Space.SE turns out to be a pretty good generator of questions for app development :)
@ManishEarth Not so easily pleased myself... now you have to got to IT Security and ask, if writing 42's to your entire disk makes it safe-erase unallocated sectors and if 54's instead woul make any difference!
2
22:29
@TildalWave I'm pretty sure my current evaluation will wipe clean all free hard disk space due to virtual memory
@ManishEarth Fun!
@ManishEarth Ouch it's that bad, is it? You're computing a rainbow table, or what?
Calculate (FluteAn[n*Pi, k] - FluteAn[0, k])/(n*Pi) for k ranging from 1 to 2 with a step of 0.001, and n ranging from 49 to 51 with a step of 0.005
@ManishEarth Blimey! Yup... you'll have to wait! LOL
That's 2*1000*400=800,000 evaluations. Of that whopper function
My progress indicator(s) tell me that I'm like 1/6th of the way through
22:34
@ManishEarth I'm still not sure I get it what you're trying to calculate tho
@ManishEarth What kind of hardware?
n=49.29, k=1.587 (k is the inner loop)
@Undo 4GB RAM + E1 Vision AMD
laptop
nothing special
Decent hardware - about how long ago did you start it?
It's a pet project, I'm not going to get access to the supercomputer for that
@Undo hmm. an hour maybe?
I paused it in between though as I needed to try something else
@ManishEarth Why not AC2 EC2?
22:36
AC2?
@ManishEarth Ya know, it's pretty easy to get access to a pretty decent supercomputer for hourly prices these days - see EC2.
@ManishEarth sorry, typo
@Undo Oh, aws. Except that this is a pet project, I don't mind running it on my comp :P
Otherwise my insti has a couple that I could use, again
I have a bunch of pet projects I run in EC2 - along with a couple wordpress sites and app APIs and Sendy.
in The h Bar, 6 hours ago, by ManishEarth
I've been playing around with a rather interesting system -- music
22:38
So maybe I can justify it.
in The h Bar, 6 hours ago, by ManishEarth
But I wanted to see how good the resonance was when compared to other notes
in The h Bar, 6 hours ago, by ManishEarth
So anyway I'm analysing the overlap of non-sinusoidal waveforms (that contain strong harmonics) with themselves at varying frequencies. I'm getting some strange results, and it seems to be like chaotic behavior with the fixed points as a subset of the notes
@ManishEarth So this is it... flute is literal there LOL... have you read Jacques Ibert's book on it?
Basically, messing with music theory
@TildalWave Nope.
I understand a decent amount of music theory. I'm trying to formalize a bit of it (it's already sort of formalized, delving deeper)
@ManishEarth you should get yourself a 3D printer and test your theories
@TildalWave I sorta have access to one. Or had access, last year
I was working for a robotics team, and we had one
Not really doing anything robotics-y this year so I don't go to the lab so no 3d printer
22:42
There are 3d-printer kits.
Not cheap, I don't think.
As in?
RepRap?
I don't know - I've seen them somewhere...
Well it's really interesting pet project IMO. I've always wondered how did our forefathers build flutes so much time ago... was it trial and error after having an initial inspiration from nature (bones, bamboo sticks,...), or a genuine insight into things we wouldn't normally attribute to "cavemen"
@TildalWave Note:I'm not actually going to be building a flute or anything :P
@ManishEarth Good.
Building a musical thingy sounds like a ton of work.
22:45
but I've already tried making one once. Was decent. Nowhere near perfect
It's not hard
Really?
Anyway, I'm not musical. The very words 'music theory' hurt my brain.
I think of music as different frequencies flying through the air. Nothing more.
@Undo string theory too?
String theory is different. It hurts my head too, but not as much as music theory
@TildalWave Even the FluteAn function is an integral of an idealized Flute waveform I created by data pulled off the Net. After this analysis I'll take the fourier transform of actual waveforms (me playing a flute, singing, a friend playing a violin, etc)
^^ prettyful!
@ManishEarth -1 for lack of freehand circles.
22:47
@Undo Not really a bunch of frequencies though. It's the harmonics that make the difference, really
@ManishEarth OK, harmonics. I learned about those in Physics. But there are really no rules to making something sound good, unfortunately.
Or at least any I can understand.
@Undo Actually no. That's what music theory is about
You can actually explain where the octave comes from
Now that's cool.
Of course, liking music is subjective. But there's quite a bit of it that is more or less objective
Huh. Might have to look into this.
22:50
Gents, I'm off to watch some science pr0n ;) @ManishEarth's fault, he's too suggestive with his charts and equations :P laters!
@Undo Technically the explanation only works well if you take the Indian or Chinese octaves/chromatic scales. The reason Western music sounds good is that its notes are approximately equal to the notes of the other two
Akk @TildalWave , now my filter's going to kick in :(
@ManishEarth Neat!
(In the diagram above, blue are the Indian notes, Red Western, and Green chinese)
Hmmm...
The western notes have their fundamentals separated by 2^(1/12)
22:52
What are the names above the chart-thing?
@Undo Chinese note names
@ManishEarth Ahhh.
I didn't know about them until ChrisWhite linked me to a pic. They are generated in a way similar to, but not the same as, Indian notes
And so I made that graphic to display how the notes cluster and why most folks can't tell the difference.
@ManishEarth Neat! I just got a music lesson I could understand!
Anyway, got to go now. Bye!
@Undo Basically, what happens is that musical instuments play notes that contain harmonics too. So a note of frequency f also contains 2f and 3f and all
22:57
Hmmm...
And notes sound good together when their lower harmonics overlap
There's something I get.
Using this you get a couple of ratios that you can keep multiplying/dividing by to get the chromatic scale
If you install Audacity or something you can actually verify this for yourself.
Huh.
Might have to do that!
Tweaking the frequency leads to a loss of overlap and it sounds bad
Or you can play an instrument not in tune with a piano or something, but you need those things to do that
22:59
I wish piano teachers talked like that.
@ManishEarth Know anything about UI design?
@ManishEarth As in, does this screenshot look good?
Just a minute...
Not bad, but could use a bit of padding on the right.
And the top block could be smaller (title and the big "Question" thing and all)
Adjust the line spacing?
Dunno
Anyway, I'll take a nap now :P
23:03
Night :)
Got lectures at 9:30
Ugh. Get some sleep!
And drink lots of coffee.
Adios!
