IBM is now letting anyone play with its quantum computer / wired

user54412

1:12 AM

IBM can't even make a good classical computer...

user54412

Also, I thought they were bought out by Lenovo.

dmckee

@ChrisWhite They sold their PC and laptop business, but kept the mainframes and the research stuff for themselves.

user54412

Ah.

dmckee

And my wife had an early thinkpap that was a tank. Later models didn't wear as well.

But they kept costing more than the competition so we quit buying them.

user54412

The mainframes are the ones that make me sad nowadays. After being spoiled by Intel chips, IBM (and everyone else) just seems 10 years out of date.

dmckee

1:17 AM

@ChrisWhite Instruction sets not providing the level of control you want?

user54412

From branch prediction to out-of-order instructions to cache management to just plain ignoring those empty loops you forced into the code to slow it down, Intel does it all. And apparently no one else can quite figure it out.

user54412

Basically their hardware does another level of optimization beyond the compiler.

user54412

But there are exceedingly few big clusters that are Intel based. They're all IBM, Cray, or GPU.

user54412

I guess the others are more cost effective or something, but it's cruel to know there is such amazing technology out there and not be able to use it where performance matters most.

dmckee

The little clusters that some of my postdoc bosses ran were all linuc PC's.

user54412

1:22 AM

@HDE226868 Are you one of the ones engaging in all the edits on the wiki page? ;)

dmckee

Sometimes even in the form of desktops, thought the bigger and beter ones were rack mounted.

Bernard Meurer

@ChrisWhite Quoting you on this matter "ICC16 can probably solve the halting problem"

HDE 226868

@ChrisWhite No; I wasn't aware of that! I came across it thanks to two questions on Worldbuilding, where nobody really understands it, either. :P

I have received warnings about vandalism being done by someone with my IP address, though, so maybe I'm sleep-editing. Scary thought.

user54412

@BernardMeurer If it can't, the Skylake i7 can.

Bernard Meurer

I was very amazed by what the ICC did on that branch prediction case, it was pretty cool

user54412

1:28 AM

@HDE226868 I think the issue with the blurry line is that deuterium and lithium fusion aren't too powerful, so even with them gravitational contraction (or maybe compositional rearrangement a la Saturn?) can be more important.

user54412

Or at least I wouldn't be surprised if that were the case.

dmckee

@ChrisWhite You have to figure that a little thing like that could pump out Virial heat for a long time before it cooled appreciably, so knowing the difference has got to be tricky.

HDE 226868

@ChrisWhite I always forget how important contraction is at those scales.

Bernard Meurer

@ChrisWhite When you start messing with optimization you begin to see how far behind AMD really is

user54412

@HDE226868 Have you read the Nature paper‌?

Bernard Meurer

1:40 AM

@ChrisWhite particlezoo.net

Have you seen this yet?

This one in particular

user54412

That's the cutest CMB map I've ever seen certainly

Bernard Meurer

Isn't it cool? I've been wanting to get one

HDE 226868

@ChrisWhite I looked at the abstract, but was stopped by the paywall. I did find a different source, though, that might be the same version.

Bernard Meurer

What's the difference between a hypothetical particle and a theoretical particle?

user54412

@HDE226868 Yeah, that looks like a preprint. In any event, it's a Nature paper, so probably wrong in some significant way.

user54412

1:45 AM

But note how they gave up on deciding if it was a brown dwarf or not.

Bernard Meurer

"brown dwarf" sounds like a very racist name

user54412

They report $0.080 \pm 0.009\ M_\odot$ as the mass

HDE 226868

@ChrisWhite Just using the phrase "ultracool dwarf" seemed like a cop-out.

Bernard Meurer

ultracool dwarf is a nice name

user54412

well it is cool :)

user54412

1:47 AM

even iron wouldn't melt on its surface, to say nothing of tungsten

user54412

as in, you could sci-fi up some story about a civilization living on the surface

Bernard Meurer

@ChrisWhite BTW you owe me money

you addicted me to chocolate coffee beans

Why have you forsaken me @ChrisWhite?

user54412

because your heart is with ACM and his trivia now

user54412

I wonder if anyone makes chocolate covered, cocaine dusted coffee beans, especially in South America

Bernard Meurer

But..but there's space for both of you!

@ChrisWhite Oh god WHAT HAVE YOU JUST DONE

DanielSank

2:14 AM

@BernardMeurer <3

Bernard Meurer

@DanielSank! <3

DanielSank

Come hang out.

Bernard Meurer

Literally or digitally? Or both?

Also, refresh my memory, is the road from LA to SB flat?

user54412

what a strange question

Bernard Meurer

@ChrisWhite I remember it being super pretty, so I wanted to bike the way there. It's about 100miles which I do at least once a month but I don't remember if I have to go by any hills or things like that

user54412

2:22 AM

I think it's pretty flat, just really curvy and indirect

Bernard Meurer

That's alright, I'm high endurance low performance in biking:p

Like most other things in my life apparently :v

user54412

When I visited SB I had a 10 mile, hilly commute by bike. Nearly killed me.

Bernard Meurer

@ChrisWhite I'm on a 50 miles daily bike routine :D

user54412

@BernardMeurer In the first world, we have machines take us places :p

Bernard Meurer

@ChrisWhite Hahaha, do you have machines that make you tan and fit yet? :p

Because my biking literally takes me nowhere

user54412

2:29 AM

Tan: yes.

user54412

@BernardMeurer I'm pretty convinced Californians don't actually go anywhere in their cars either. They just drive for the sake of clogging up roads.

Bernard Meurer

Haha, yeah there was a lot of traffic when I was there

but still a bliss next to Rio's roads

DanielSank

@BernardMeurer There is a part where you go over a small mountain.

Very small.

On bike it would be arduous.

But people do it.

Bernard Meurer

@DanielSank Grab your car wait me there, get me over the mountain and we meet at SB :p

DanielSank

@BernardMeurer k

Bernard Meurer

2:35 AM

Oh no you didn't just 'k' me

DanielSank

Actually, you on a bike has a higher probability of making the trip to L.A. than does my car.

@BernardMeurer Uh... is that bad?

Bernard Meurer

@DanielSank Every time I received a 'k' from a girl it ended up horribly; I'm still deciding what it means for other people

Ha, I remember my first comment when I came in the lab was "Hey, cool bike" to which you replied "Nah, it's a piece of crap"; Do you not have any good means of transportation?

DanielSank

@BernardMeurer Are you trying to get my to go home with you?

@BernardMeurer yeah.... at the moment my transportation options are crap.

Bernard Meurer

@DanielSank You're an engaged man!

DanielSank

@BernardMeurer Yes.

How's Isabel?

Bernard Meurer

2:38 AM

I'd only do that if you had very large breasts

Okay, nevermind that was unethical

and immoral

DanielSank

Not really immoral... people can choose however they want.

Bernard Meurer

She's alright, we've been talking a lot and she's surprisingly nice

I have trouble engaging in long conversations, I get distracted and drop random comments, she seems to rather enjoy that

DanielSank

Your sense of humor is awesome.

Bernard Meurer

Unless you're referring to the de facto Isabel who, last time I checked, was very octopussy

Ha, that word worked out nice

DanielSank

heheh

Bernard Meurer

2:40 AM

@DanielSank Thanks! That's generally a controversial subject

DanielSank

Well, you take my jokes without explicitly acknowledging them. I appreciate that a lot.

hmmm, why is the "thonk" ping sound on SE chat so incredibly unceremonious?

Bernard Meurer

Oh god, I just got blueberry juice all over my white pajamas

This will be hard to explain in the morning

DanielSank

@BernardMeurer Take that.

Bernard Meurer

Ouch, my ears

DanielSank

@BernardMeurer Really?

Can't you say "I spilled blueberry juice"?

You explained it to me rather effectively.

Bernard Meurer

2:43 AM

@DanielSank My mother last saw me at 10:30 PM when I said goodnight and there was no juice in this house

DanielSank

@BernardMeurer I see.

Bernard Meurer

I left home at night in the rain to buy blueberry juice because I had an inner craving

that'll be hard to explain :p

DanielSank

"I went and purchased blueberry juice. Then I spilled it."

?

Bernard Meurer

I'm glad I'm not a woman, I'd be so weird during pregnancy

@DanielSank We're brazilians, that's not how it works :p

DanielSank

@BernardMeurer You don't trade money for goods and services?

Bernard Meurer

2:45 AM

Hahaha, with our current currency value I'd say we trade monopoly money for goods and services

It's just unusual to leave home after 10:00 here, it's somewhat dangerous where I live

specially to buy juice

and it's kind of a far walk

but IDK my brain said bed but my heart said juice

and I'm a romantic

DanielSank

hahahahaha

Well my heart said tomatoes and chick peas, so that's what's on the stove.

Bernard Meurer

Ah, chick peas, those make a funny sound when you eat them

I like that

DanielSank

They do?

Bernard Meurer

Idk, in my head they do

That doesn't mean much though, a lot of stuff happens there

Isn't this just dancy as hell?

Oh, and Dan, on the good news side of things, I just passed to the third phase of that full coverage 'wherever you go' scholarship program; after the interview Friday there's only one left for me to get in :)

DanielSank

@BernardMeurer Wow!

Bernard Meurer

2:55 AM

@DanielSank Pretty neat right? This blueberry is well deserved

also on related news I'm now 18 and a big boy

DanielSank

@BernardMeurer yep

By the way, I was just watching the 3-way standoff scene from The Good, the Bad, and the Ugly when you pinged me.

I almost jumped out of my chair.

@BernardMeurer Hahaha, you want a cookie?

Bernard Meurer

Hahahaha I'm telling you this ping is from hell

dmckee

@BernardMeurer Depends how you. Most routes have at least one good sized hill, and some have several. I think sticking with the coast highway might be the best bet for avoiding hills, but it'll put you in some narrow places without proper bike lanes and with manic drivers.

Bernard Meurer

@DanielSank I'll take a cookie :)

DanielSank

Of course you will.

Cookies are awesome.

Bernard Meurer

2:57 AM

YES, and tremendously hard to find around here! Quality ones at least

DanielSank

eh?

You mix sugar, eggs, flour, etc. in a bowl and then bake it.

It's pretty quick.

Bernard Meurer

@dmckee Nice tip! I bike on Rio de Janeiro's traffic though, I think I can take a CA road :p

@DanielSank The only thing I can cook are bad jokes and explosions

DanielSank

I see.

Try making scrambled eggs to start.

You should move to CA.

I'll show you how to cook.

Bernard Meurer

I can make fried eggs!

DanielSank

@BernardMeurer ok, then graduate to cookies.

Bernard Meurer

2:59 AM

They're not good but my cousin ate them once

I know I should! I'm working on it, if the scholarship doesn't go through there's another guy who offered to sponsor half my tuition

DanielSank

How much dynamic range is there in fried eggs quality?

@BernardMeurer Nice.

Bernard Meurer

@DanielSank Quite a lot, taste mine and my grandmothers and you'll see

from Lil'Wayne to Mozart

Actually I'll change that, to Ravel, I like him better

DanielSank

This is going to sound slightly dumb...

Mozart is incredible.

Really, truly amazing.

Bernard Meurer

Why is that dumb?

DanielSank

Well, because I think a lot of people would say it's obvious.

Anyway, there are very few pieces of music I listen to without disagreeing with some parts.

Bernard Meurer

3:04 AM

He is incredible, and is certainly one of the greatest composers of all times

DanielSank

But Mozart... everything is just right.

Bernard Meurer

That doesn't make it less true :D

DanielSank

I have no disagreement with anything in his music.

Bernard Meurer

That's Grieg for me

DanielSank

He embellishes without sounding tacky.

Bernard Meurer

3:05 AM

Ah, Morgenstimmung

DanielSank

It's just amazing.

Bernard Meurer

What a piece

I like Mozart's Piano Concertos a lot

20 and 22 specially

DanielSank

I listen to them, thanks.

I don't often listen to piano music.

Bernard Meurer

You like orchestral? String Quartet?

Flute solo?

Hand clapping rap?

DanielSank

Flute is a wonderful instrument.

I like most music. Opera not as much.

Bernard Meurer

3:07 AM

It really is, my grandfather plays it

DanielSank

I'm not usually too inclined toward vocals and opera sort of relies on it.

Bernard Meurer

I only like Wagner's stuff in Opera

Yep, same thing, not a fan of vocals

DanielSank

I played this for a while with a flute playing friend of mine.

Bernard Meurer

I'm so obsessed with Ravel's Daphnis et Chloé I have 3, 4th on the way, different recordings of it

DanielSank

@BernardMeurer Ok I have to write this all down.

Bernard Meurer

3:09 AM

That reminds me of Brazilian classical compositions

It's a lot like that one

Didn't know you played the guitar

DanielSank

yes

I'm not good anymore because I haven't played in several years.

I used to be reasonably ok.

Bernard Meurer

DanielSank

Flute is one of those really awesome instruments that's unique and has no crappy aspects.

Bernard Meurer

If this stands to show anything, word analysis on my library :p

DanielSank

It shows you listen to classical music.

heh

Bernard Meurer

3:11 AM

Same with me but Piano

DanielSank

ehhhhhh

Ok, I'm not criticizing your tastes, please remember that... I'm just voicing my opinion.

The piano has a lot of sound, probably because of how the hammers work, that seems to get in the way of the notes.

Bernard Meurer

What? You don't like exactly what I like? I'm sorry I don't think we can be friends anymore

You mellon

:)

DanielSank

@BernardMeurer mellon? What?

Braziallian slang?

Bernard Meurer

@DanielSank Nope, just my awkwardly specific memory at work

Apr 15 at 5:42, by DanielSank

Hey, @BernardMeurer, you're a mango. Ha, take that.

DanielSank

I also just... I think a lot of piano players just sort of bang out the notes without giving the music texture, and for some reason this is considered "good" in the piano world.

@BernardMeurer Hahaha, nice.

Bernard Meurer

3:13 AM

I remember all these things, I'm weird like that :p

It's a virtuoso thing, banging notes like a mechanical man

Some like it some hate it

I think soul is what set's western pianists apart from eastern ones (rough generalization of course)

DanielSank

Wait a minute... eastern pianists?

wut?

Bernard Meurer

Here in the West, specially Europe, there's less value to the 'mechanical' precision of the piece

IMHO of course

Yeah yeah, Russians, Ukrainians, Chinese

They generally have a school of thought in piano more towards precision than interpretation

Check the song I just shared to your drive for example, what makes it great is the interpretation work put into it

It'd be hard to find some virtuoso that would play that well

@BernardMeurer found a reddit thread about the best scenes in movie history. Watching on youtube. So far they're really good.

Bernard Meurer

Do link!

DanielSank

3:19 AM

The stand off I told you about, Maximus's reveal in Gladiator.

reddit.com/r/AskReddit/comments/4hw9ct/…

Bernard Meurer

My favorite is by far the ending scene of Dr.Strangelove

DanielSank

@BernardMeurer That movie is so weird.

Bernard Meurer

that made me cry, and that rarely happens with movies

DanielSank

@BernardMeurer oh wow

I wasn't really into it when I watched it. Might have been a defense against getting too depressed.

Bernard Meurer

@DanielSank I get attached to weird things

Dr.strangelove ending (good quality)

►

The song man, that song

It has a very special meaning to me

Which I can explain if I have a beer one day :D

Watching Il Triello

DanielSank

3:23 AM

@BernardMeurer Have you seen the film?

That scene is awesome in context.

Bernard Meurer

@DanielSank Not yet sadly, I'm going to tomorrow though

What a scene!

and the music too!

DanielSank

yeah

don't watch the end!

zomg if you haven't seen the movie stop!!!!!

Bernard Meurer

OKAY OKAY

I stopped before the end

Oh yes the Gladiator one is great

DanielSank

yeah

I think I'll watch that film again.

Bernard Meurer

I was thinking the same thing!

Princess Bride - My Name Is...

►

This one is damn good too

DanielSank

3:31 AM

Yeah, that's a classic.

Bernard Meurer

Lectures was the wrong folder :p I shared the right one now

Lectures are well, lectures, by Simon Rattle on how to play Sibelius' symphonies

DanielSank

I'm trying to figure out how to share google photos with you without sharing all of them or making them public

Bernard Meurer

Select the ones you want

then click right click and share

DanielSank

If I do that I get an option to give out a link.

That means anyone with the link can view.

I don't want that.

Bernard Meurer

What about the "more options" button?

DanielSank

3:35 AM

I want it to work more like Google Drive where I can set who is allowed to access the link.

Bernard Meurer

Wait aren't we talking about google drive?

DanielSank

Not quite.

The photos program is separate.

Bernard Meurer

Picasa?

DanielSank

It's not called that any more, but yes.

Bernard Meurer

I think you click "New shared album"?

Nope

That makes a link

Bloody hell google

DanielSank

3:41 AM

They usually have reasons when stuff is dumb like this.

Sometimes the reason has to do with technical problems and some times it's because of user experience trade-offs.

If you think about it, the way Drive works is awesome and kind of unique.

I think you can share photos with specific people via Google+.

Bernard Meurer

I think you can via G+ yes

Drive is AMAZING

DanielSank

Does this work:

goo.gl/photos/RkJtX5vBdNFxi9D19

Bernard Meurer

Is it a single photo of food?

DanielSank

Yes.

@BernardMeurer Yeah, it's basically Unix permissions over the internet.

Bernard Meurer

That looks very tasty

DanielSank

3:45 AM

@BernardMeurer Just made it. It's so good.

Bernard Meurer

@DanielSank yes, hadn't thought of that before

What's that background?

DanielSank

@BernardMeurer My table cloth.

I've been making my apartment look nicer recently.

Bernard Meurer

I was about to say, It's very pretty

DanielSank

Thanks!

Bernard Meurer

Doesn't getting married automagically do that for you?

DanielSank

3:49 AM

heheheh, perhaps.

Here, I'll show you some more random photos... one moment.

Bernard Meurer

I'm only getting married when I need furniture

DanielSank

@BernardMeurer This is nice, I'm learning how Google photos works.

Check your email. You should have a link.

I guess the links can be considered cryptographically unguessable, but I'd rather my cryptographic tokens not be transferable!

Bernard Meurer

Yep, just got it

DanielSank

Capabilities model, remember! That's what we want!!! Capabilities should not be automatically transferable.

Bernard Meurer

That butterfly one is cool!

YES!

DanielSank

3:53 AM

@BernardMeurer I grow butterflies.

When they're in season.

Bernard Meurer

Oh I have a story you'll like

DanielSank

A lot of them died this year.

They got a fungus or something.

Bernard Meurer

Is that snow one a little after I visited?

Yikes, that's a shame!

DanielSank

@BernardMeurer No that was many years ago.

Bernard Meurer

Dat mug tho

DanielSank

3:54 AM

YES!

Bernard Meurer

Damn I like your view

Isabel!

DanielSank

It's so awesome. It looks like the octopus is tasting the beer!

Bernard Meurer

THAT FOOD OMG

DanielSank

Actually, that is Lauralie, in Baltimore.

Bernard Meurer

THAT FOOD OMG²

DanielSank

3:55 AM

@BernardMeurer Yeah bro. Cooking is legit.

Bernard Meurer

Some cows

THAT FOOD³

DanielSank

@BernardMeurer In Davis California. Drove up there with friend.

Bernard Meurer

Ah, I had heard that UCD smelt like cow dung

DanielSank

Hmmmm, most of my photos are food...

Interesting.

Bernard Meurer

Tells something about you hahaha

You should be fat, this is unfair

God why have you forsaken my metabolism

And the butterfly thing was just that I once went to a MASSIVE butterfly vivarium

DanielSank

3:57 AM

@BernardMeurer I eat mostly healthy stuff, and then a lot of chocolate.

@BernardMeurer Oh yeah? Cool!

Bernard Meurer

Yeah it was amazing man! I had never seen so many butterflies

DanielSank

It's hard to get fat if you cook your own food.

goletabutterflygrove.com

This is five minutes from my apartment.

Look at the photo gallery.

Bernard Meurer

Damn the pictures are so cool

Yep, hahaha

Very cool

Is SB housing expensive?

DanielSank

@BernardMeurer Depends.

Most of it is.

Bernard Meurer

Dang it

DanielSank

4:03 AM

But, if you're patient and friendly you can share a nice house and pay maybe $500 per month, which is perfectly fine on a grad student stipend.

Bernard Meurer

500 sounds reasonable

DanielSank

It is but that's the lowest you'll ever find.

You can share a perfectly good apartment with one other person and pay $800 per month.

In a nice neighborhood, close to the beach.

Bernard Meurer

That sounds better

I like to swim at night a lot when I'm anxious

so basically every day

IF I get that scholarship I'll have a considerable amount of extra money

the people I know who got it live very well (for a student)

@ChrisWhite: that's a great answer. I have to confess that when I sat down to answer yesterday evening I couldn't be bothered to write at anything approaching that length.

user54412

@JohnRennie You've caught me avoiding work I see.

user54412

I'm actually somewhat surprised how effective it is.

John Rennie

@Danu Honestly, it's not worth it. What I meant by my answer was your question is crap but here's the way to think about it if you're really interested. However I'm not sure the message got through.

As for the effect of the HNQ, look no farther than this rather obvious answer currently at 116 upvotes.

Or this answer about a chair at 196, yes that's 196 upvotes. But maybe I'm being elitist here - if people enjoy reading an answer why shouldn't they upvote it?

@ChrisWhite I started work 20 minutes ago, but haven't done any yet :-)
