12:04 AM
you know when you said a bit ago when we were talking about tensors that the definition would need to be revised when I got into GR/SR/all that?
@ACuriousMind
 
well, i started reading a bit about GR
*listening to a video about einstein's field equations
not reading
 
12:16 AM
@ACuriousMind eh?
 
@DanielSank I find the text not being justified much worse for my reading experience than the font, for example
 
obe
12:42 AM
@ACuriousMind 0celo7 asks how in-depth your FA class went into the boundary conditions relating to Sobolev embeddings.
specifically: if a Lipschitz condition on the boundary implies a cone property

@obe: Hey! Are you Ice lord or was that Obliv?
 
@Kaumudi.H, hello!
 
user228700
@heather Hi :-)
 
@BernardoMeurer, hello to you too!
 
obe
@Kaumudi.H I was obe when I left.
so I don't get what you're asking.
 
user228700
@obe I'm asking if at any point of time your name had been Ice Lord.
 
obe
2:30 AM
yea
 
user228700
Cool. Glad that you're back :-)
 
obe
thanks.
 
@heather Howdy
 
i heard you're transferring to canada.
best of luck =)
 
Last night dream is a platformer game of some kind where the ending hints at a very dystopian story:
 
2:40 AM
I think I'll be trying yeah :)
Thanks
@Secret I literally talk about your dreams every day to people
 
Ending text:
"Eventually it was discovered that among the human |male female (forgot) (forgot)|, the females and the last surviving (forgot race name start with C) male were found to be at its prime. Eventually an eurasian female was produced who was the first one to be free of any genetic errors. Since then those who are terminally ill have been receiving constant transfusion of the perfect genetic cells to prolong their lives."
"It may also serve as a cautionary tale to the situation in Hong Kong."
 
obe
@BernardoMeurer you're transferring to canada?
 
user228700
@Secret Where is the starting text? This sounds a bit like Divergent, now I'm curious...
 
@obe Applying
 
obe
where to?
 
2:42 AM
There is no starting text, the whole thing is a platformer flash game where the main character is an eurasian female (although appearance is white blonde) and throughout 6 levels, you played as her as she made her way to the exit
 
user228700
@BernardoMeurer Good luck :-)
 
the ending is kinda bleck when you realise that...:
 
user228700
@Secret Ohh, I thought you were describing a dream.
 
At the final level, which is layered on top of some old marvel comic like drawing style showing a crowd of humans, along with a comic panel on the right showing the blonde woman seemly resting on a basic hospital bed receiving some kind of transfusion and
look content but tired. The game eventually end when the woman character jump slightly to the right which is then replaced by a similar panal of the woman on the hospital bed. The level then fade away and replaced by the following ending paragraph:
 
@obe UW and UT
 
2:43 AM
It is my last night dream
 
@Kaumudi.H God bless
 
Ihave no idea why it can fabricate so much stories recently
That is, the whole game take place WITHIN the dream
Here's how it started:
 
user228700
@Secret That's crazy. Say, dyou feel refreshed after waking up from one of these dreams?
 
Playing a game where the main character is a blonde woman character (wearing gray t shirt and dark trousers. Reminds of gym and action females in various movies). The
game is perspective 2.5D and has 6 dark levels took place among building tops. The woman jump from the top of some dark buildings, avoiding the white square spotlights as she carefully made her way down to the exit at each levels. Level 5 has conveyor belts and some electric flooring of some sort. In level 1, there are also some hoodie guys roaming around that does not seemed to do anything.
@Kaumudi.H Well, I feel quite normal, neither refreshed nor tired
 
user228700
@BernardoMeurer :-) Hereabouts, "God bless" is only told by the elders. Is this the case in your culture as well?
 
2:46 AM
This is what level 1 roughly look like:
You start at the top of a building and work your way down. Many hoodie guys walk around in the streets but they don't seemed to do anything
And this is roughly what level 5 look like
 
@Kaumudi.H As it so happens, yes, I hadn't thought of this. It's something my grandmother would tell me.
 
The long light gray rectangle is a conveyor belt and the 3 grate looking things are electric plates
 
I say it to people though
 
As for the story itself, it strongly reminds of the Mazerunner triology, such as the theme of transfusion and harvesting people to prolong a dying society
 
user228700
@Secret Wow, you were able to remember and draw/design a picture?!
 
2:49 AM
It's not common to have such vivid dream recall, but they do happen
Btw, there's another wall of text after I finished that game and close the window:
"Time travel done right:
Many stories like to include time travel simply because to give a very loopappro(forgot)aloop impression
However all characters must exists WITHIN the loop (drawing of a rectangular loop). Please ensure this when writing a time travel story
Please refer to the following (7 minibook icons including Doctor Who, Time Travelers wife etc.) to ensure that!
(rest of text not read and then I proceed to the powerpoint (in the dream) to recreate the game scenes)
 
user228700
Firstly, Do not spoil the mazerunner trilogy because I haven't read the books (and don't plan on it--I have read too many dystopian novels for my liking already) and will watch the last movie when it comes out.
 
user228700
Secondly, when I read the Ending text, it reminded me more of Divergent.
 
oops, sorry I did not knew you haven't read mazerunner. Apologies
 
obe
@BernardoMeurer nice
good luck
 
user228700
@Secret No problemo :-) You didn't reveal anything that I don't know already but I only wanted to bring light to the fact that I'm waiting for the last movie and it would be nice to watch it un-spoiled. Hang on, let me read everything you posted just now... (Usually, I don't understand much of your dreams because it involves geometry so I don't bother to read everything:-P)
 
obe
2:53 AM
@BernardoMeurer if you come to UT we can be best friends.
 
@Kaumudi.H ...one possibility is that I watched the 3rd movie (Allegiant) on a plane by accident last year (saw that when I peek through the seats and the passenger in front of me is watching it as it near its end)
 
@obe I owe you a lot of coffee
 
my dreams are known to include a lot of peripheral data received from my senses
 
@Kaumudi.H not spoiling, haven't watched the movie, but the books are terrible
 
obe
lol
 
2:55 AM
My first thought after reading that time travel text and waking up is the following: Are these really MY thoughts?
 
user228700
@Secret I haven't watched Allegiant and I hear that it's nothing like the book. Dyou plan on reading the books?
 
@obe Do you have a car?
 
I am usually not patient enough to read novels (although I do get dragged in easily). I used to have that patience when I was young
 
user228700
@heather Thanks for the heads-up. I was debating about whether or not I should give it a go but now I will not :-P
 
obe
@BernardoMeurer no, there's no parking here lmao
 
2:57 AM
I always felt like I have alot of task need to do except the schedule always end up trashed into the drain as I browse facebook like a zombie
 
@obe I'll need a canadian with a truck for moving lol
Gotta move all my vinyls
 
user228700
@Secret I absolutely love that you used the phrase "peripheral data received from my sense" to describe watching a movie by peeking at it from behind as someone else watched it on their screen.
 
@Kaumudi.H read the Giver series, four books, absolutely fabulous, by Lois Lowry - dystopian, but good dystopian. and i'm not a dystopian person.
 
user228700
@heather Ooh, I have heard of it. Will try to obtain a copy in the summer, thanks!
 
For that dream last night, I also strongly suspect that the fact it is rendered in 2.5D birdeye view might have something to do with yesterday's discussion.
 
user228700
2:59 AM
@Secret Oh, I see. Well, in the book, Tris dies at the end. Many many people (excluding me) hated this ending, which is why they changed the movie so much.
 
obe
@BernardoMeurer It's kinda early to discuss these things but will you stay on residence or rent a place?
 
@Kaumudi.H four books: The Giver, Gathering Blue, The Messenger, Son
 
Well, the movie has this big difference, basically what you said have already spoiled about Tris
 
@obe No clue, probably residency b/c it's cheaper when it comes built into the tuition like @ UW
 
user228700
@Secret One time, I dreamed about a game. Unfortunately, I woke up but when I fell back asleep, the dream continued from where it had left off! It was the only time it happened and I am so grateful that it happened especially during a night in which I had dreamed about something so vivid.
 
obe
3:01 AM
@BernardoMeurer UW is in a boring city, I don't think you would want to go there.
 
user228700
@Secret What other difference is there? I don't care so much for watching the movie...
 
@obe I'm a boring man
 
user228700
@heather Oh, I see. Thanks :-)
 
enjoy =D
 
and Isn't Waterloo close to Toronto?
 
user228700
3:02 AM
@heather In the summer! :-)
 
@Kaumudi.H Well if my memory serves: Tris lives, the group managed to stop the gas spreading and the bureau of whatever's existence is revealed to the public
 
obe
@BernardoMeurer 1.5 hours driving.
 
At what speed?
 
obe
highway speed.
 
user228700
@Secret Oh, I see. Hmm, IIRC, that's not too different from the books. I wonder what everybody was going on about. I preferred the ending in the book tho--she dies and there is a beautiful scene in which Four goes zip-lining through the broken city of Chicago and spreads her ashes all around. It is all the more touching because Four is afraid of heights but does this for her.
 
obe
3:05 AM
it could be less if you're lucky, maybe 1 hour. @BernardoMeurer
 
user228700
Anyhoo, @Secret: Your brain is fascinating, to the say the least.
 
Meh than why would I not live in Waterloo? I can't take >1h every day to get to class
 
obe
if you're going to UW you will have to live in Waterloo duh.
 
I already feel tempted to not go to class and I live 1.4km away lol
 
That happened to me roughly 4 times per week, although it really only count waking up at bed and going bed to sleep again. If I left the bed and go back to sleep, the dream will not continue.

I have dreams of a wide variety of structures. Seen many characters from Satan to God to Santa Claus to celebrities to my friends etc. Have experienced many crrazy spacetime geoemtries etc.

...The only know dream structure I yet to have is a "sequel dream" a dream that continues the story of where a past dream left of, and also recurring dreams.
 
obe
3:07 AM
@BernardoMeurer I know that feel.
 
There are still some things I don't understand about my dreams: As 6 years worth of dream logging have shown, my mind seemed to remember intensely a lot of peripheral data that I (at least my conscious self) don't think or have reason to think they are interesting.
I have no idea why they so secretly caught my attention so strongly, to the extent that they manifest in my dreams
 
user228700
@Secret I would absolutely love to talk about your dreams more but for now, I have to finish some chapters :-(
 
ok
 
@Kaumudi.H, have you studied general relativity at all?
 
user228700
@heather 3 years ago, I studied it just a little bit for fun but I have long forgotten whatever little I learned and plan on taking it up in University later this year.
 
3:20 AM
ah, okay.
 
rob
4:14 AM
@vzn Wow, 10% is an amazingly high response rate for a survey like that. I probably would have tossed the thing.
 
vzn
4:35 AM
@rob so it apparently had a slightly higher status than junk mail although some hardcore copenhagenists might disagree. not sure if he emailed it or mailed physical copy, seems to be the former. his professional affiliation/ background might have helped with responses. it would be interesting to read his cover letter. its the ~3rd in a set of surveys/ polls over last few years since 2013. maybe triggered by this one, they seem to have been rediscovered lately by reddit crowds.
 
 
2 hours later…
user228700
6:10 AM
@JohnR: Morning! :-)
 
Morning :-)
 
user228700
@JohnRennie The air is filled with smoke because:
 
user228700
Bhogi (భోగి: Telugu) (போகி: Tamil) is the first day of the four-day Pongal festival. According to the Gregorian calendar it is normally celebrated on 13 January but sometimes it is celebrated on 14 January. In Tamil Calendar, this corresponds to last day of the Tamil month Maargazhi. It is a festival celebrated widely in Tamil Nadu, Andhra Pradesh and Telangana. On Bhogi, people discard old and derelict things and concentrate on new things causing change or transformation. At dawn, people light a bonfire with logs of wood, other solid-fuels and wooden furniture at home that are no longer useful...
 
Is it during Pongal you eat that sweet rice dish?
Or am I thinking about a different festival?
 
user228700
Ooh, you know about the sweet dish?! (Yes, that is correct)
 
6:13 AM
It seems a bit like the UK rice pudding
 
user228700
How do you know about it?
 
Rice pudding is a dish made from rice mixed with water or milk and other ingredients such as cinnamon and raisins. Different variants are used for either desserts or dinners. When used as a dessert, it is commonly combined with a sweetener such as sugar. Such desserts are found on many continents, especially Asia where rice is a staple. == Rice pudding around the world == Rice puddings are found in nearly every area of the world. Recipes can greatly vary even within a single country. The dessert can be boiled or baked. Different types of pudding vary depending on preparation methods and ...
 
user228700
Hmm, it is similar but I don't like Pongal (the dish).
 
I can't remember where I heard about pongal. It's just one of the things I've always known.
I love rice pudding :-)
In fact I had rice pudding for lunch yesterday
 
user228700
@JohnRennie Hmm, I didn't think that the festival or the dish was famous at all!
 
6:15 AM
Maybe my father mentioned it
 
user228700
@JohnRennie Oh, nice :-) I actually don't like sweets that much--I only like Rasgulla and Gulab Jamun and of all the other varieties of "sweets", I like some kinds of pastries and dark chocolate. That's about it. When I eat some varieties of sweets that I don't particularly enjoy, my nose itches :-|
 
Have you ever had mint fondant?
Sometimes called mint creams
 
user228700
@JohnRennie ...and this is why I don't go so far as to say that I hate sweets; you see, I haven't had many sweet dishes made outside Indian homes.
 
They are my favourite sweets
 
user228700
I see. If I find them, I will try them out :-)
 
user228700
I don't use eggs :-( I wonder if there is a substitute...
 
Fondant doesn't use egg
 
user228700
> "1 free-range egg white"
 
user228700
^ ?
 
You mix water, glycerol and sugar and boil it until the mixture thickens. Then let it cool until it's just starting to crystallise and beat it vigorously.
As the sugar precipitates it forms a soft solid.
 
user228700
6:23 AM
Wait, what are u describing?
 
Add mint flavouring to make mint fondant. It's an alternative way of making mint creams. It's more difficult but they are even better than the ones made with egg white.
 
user228700
Oh, I see. Hmm, they do seem ridiculously easy to make (as desserts go anyway)!
 
user228700
Perhaps I'll make them on a slow day :-) Thanks! (::Copy-pastes the recipe::)
 
user228700
...however, I must add that I've never been a big fan of mint.
 
user228700
6:27 AM
Oh, I see. Have u heard of Hajmolas? (Hehe)
 
Googling suggests that's a cure for indigestion :-)
 
user228700
:-) Yep, that is correct, although not always ingested only during ingestion problems.
 
user228700
People eat it like candy.
 
user228700
x'D Exactly.
 
user228700
6:35 AM
My mum bought one bottle, which we finished in about 3 days, after which we didn't buy another lest we become addicted--this was about 8 years ago and I haven't had it since.
 
It seems to me that the UK has the widest, and possibly the best, range of sweets of any country I've been to. Maybe excluding the US ...
 
user228700
I see...(?)
 
India doesn't seem to make sweets with just sugar.
They are more like what we would call cakes.
 
Aren't the Swiss famous for their chocolate?
 
user228700
@JohnRennie x'D That's true.
 
6:37 AM
@Pissedofflayman they have a good reputation for high quality chocolate, but they don't have the huge range of sweets that you get in the UK.
Hi @rob. Don't mind us, we're talking about sweets :-)
 
user228700
...food. As always :-P
 
rob
True story: I traveled from the US to Switzerland for a conference several years ago and was excited to try famous Swiss chocolates.
At home I get the higher-end stuff from the grocery store: Lindt, Toblerone, Ferrero Rocher
The first chocolatier I visited in Switzerland was selling ... Lindt, Toblerone, and Ferrero Rocher
I concluded that I was doing something right
 
@rob Toblerone and Ferrero Rocher are somewhat overrated I feel. I don't like their taste. Lindt is better :). But I don't think these are the predominant chocolate companies in Switzerland (though I have never visited that place) :)
 
rob
@anonymous I found some others eventually.
 
@rob You remember any names (of the other chocolates) ? I too had some Swiss chocolates but as always I forget their names :P. I love the bittersweet aftertaste of Swiss chocolates :).
 
rob
6:49 AM
@anonymous No, the others had wrappers in German, no recollection at all.
 
I see :P Same happens with me!
 
Is this question have something to do with physics?
 
@Ramanujan Obviously it is. Also a good puzzle.
A potential candidate for Puzzling Stack Exchange maybe.
 
How are your studies going @anonymous
 
@Ramanujan I agree that will be a better fit.
@Ramanujan Good. Moving fast :)
How's yours ?
 
6:57 AM
Need to learn alot
 
@Ramanujan Good luck!
 
user228700
7:54 AM
@JohnR: Oh, I only just remembered! Any news on the refund?
 
8:07 AM
In the end I didn't chase it. I didn't want to get the guys in the Indian office in trouble.
 
user228700
@JohnRennie So how should we go about paying you?
 
[Rambles]: Given a bunch of functions, if they are not injective, then for each mapping the kernal only grew bigger and bigger.

How to reverse a kernel? By breaking symmetry in the function so you have enough degrees of freedom when composing them together to regenerate the parts that are lost in the kernel
 
@Kaumudi.H Don't worry about it :-) After all I could have got a refund if I wanted to, so I don't see why you should pay simply because I'm squeamish about getting people into trouble.
 
user228700
@JohnRennie .__. That doesn't seem right.
 
@Kaumudi.H it seems fine from where I'm standing (sitting) :-)
@Kaumudi.H my next potential laptop ...
 
8:21 AM
Nice, should be yours in just under 10 hours.
 
user228700
Brb.
 
maybe ...
I want a laptop with a 17" 1080p screen, but that laptop has a relatively low powered processor and the battery will probably need replacing because it's three years old. So I won't pay much more than £200 for it. I suspect it will sell for more than I'm willing to pay.
But that's OK. I'll just wait for the next one ...
 
@JohnRennie Wow! That's almost 3 times cheaper than a new Inspiron 7720! (Seems a bit suspicious though :-P)
 
They'll be plenty of good deals out there.
 
8:28 AM
@anonymous bear in mind that the new Inspiron comes with a 6th generation i5 while that laptop has a 3rd generation i5. Also the new one has a 3 year warranty while obviously the old one doesn't.
£200-300 is about right for a laptop of that age and specification.
 
@JohnRennie Oh. Now I see. I didn't notice the processor specifications. Got it now :)
 
It's always a bit of a risk buying old laptops because you don't know how much longer they will work for.
But I can fix most problems with laptops so I'm not too worried.
 
a bit of a handyman?
 
@JohnRennie That is awesome! You can fix hardware problems also ? From where do you buy the spare parts ?
 
@anonymous I do work for an IT support company. They get old broken laptops returned from customers and I take them. So I can use parts from broken laptops to fix other laptops.
However this only applies to Dell laptops because the IT company deals only with Dell.
That's why I only ever buy Dell laptops on ebay.
Sometimes I have to buy parts, and if so I generally get them from ebay.
 
8:38 AM
I see. Wow :) I've always had a bad luck with laptops. Each one of my previous laptops (mostly Dell and Samsung) developed some kind of problems within 6 months of usage :P. I guess this current laptop is the 10 th one. Unfortunately in my place hardly any store can fix laptops :P And if I use the company warranty then they take over 2-3 months to fix and return it ! I think I need to learn to fix laptops myself from now on :D
 
Have you tried YouTube for fix it yourself ideas?
 
@anonymous software or hardware problems?
 
Preventive maintenance works for me :-)
Contrasted with corrective maintenance.
 
For software the no. 1 rule is do a clean install of Windows then don't frig about with it. Don't install dubious software from dubious web sites. If you don't bugger about with it your Windows installation should stay fast and responsive for years.
For hardware there's not a lot you can do. It isn't like a car that needs servicing once a year.
 
user228700
Sorry about the timeout, something terribly important came up.
 
8:52 AM
@Kaumudi.H Lunch?:-)
 
user228700
@JohnRennie :-) No, my mum is not feeling well.
 
Oh! :-(
Nothing serious I hope?
 
user228700
No, no :-) She'll be fine, thanks.
 
user228700
So. New laptop huh? Hang on, lemme read the transcript...
 
user228700
8:55 AM
:-o Weren't u a bit wary of them?
 
user228700
Oh, crap, BRB.
 
They're not an obvious buy for me. If I wanted sweets I'd buy sweets. But I'm curious now.
 
@JohnRennie You can clean out the fan to keep it from over heating.
 
@JohnRennie My last laptop fell on the floor once (about 3m height ) and from then on it used to shut down automatically every half an hour or so ! The one before that developed a problem in the speakers (no sound ) and cursor. And so on...
 
@Pissedofflayman I don't think I've done that with my laptops. Well, not unless I had it open to do something else e.g. upgrade memory.
> My last laptop fell on the floor once (about 3m height)
Not many laptops will survive that unscathed :-)
 
8:59 AM
Actually it might be a bit less like 2.5 m or something :P .I wish laptops were a bit more flexible :D. As I said I have a terrible relationship with laptops :D
