The Nineteenth Byte

hosch250

18:00

It won't look very good.

Rainbolt

How did I end up with an image that is sharper than the original?

hosch250

My guess is you enhanced it somehow. Geobits is really fuzzy, and yours is crispy clear.

Oh, it is because Geobits is so far down the chat line.

I think.

Beta Decay

Yeah, that makes sense

Wait, no, durron's avatar is still crisp

hosch250

So is Geobits when you hover over it.

Not as crisp though.

I think Rainbolt used a lower resolution when he swapped it or something.

That might cause it somewhat.

Or else the swap enhanced the image.

@Rainbolt We should make a smiley with our avatars.

Beta Decay

Geobit's avatar is hosted on Gravatar and Rainbolt's is on imgur. That's probably it

hosch250

18:04

That could be it too.

Geobits

We should just get everyone to use scrabble tiles. Then we could play with words in the list.

hosch250

That could be exciting.

Geobits

l

hosch250

@BetaDecay QUICK!

Geobits

k

hosch250

18:07

@Bet QUICKQUICK @BetaDecay @BetaDecay

Geobits

:P

hosch250

:)

Geobits

:(

hosch250

:<))

Geobits

Ok, enough fun. Line it up whenever :D

Beta Decay

18:08

How does @Bet still notify me?

hosch250

this

YES!!!

Geobits

That looks terrible.

Rainbolt

Lol

Geobits

You could have at least given me an eyepatch or something

hosch250

Now everyone pin it:

6

Beta Decay

18:09

You've got a very pointy hat...

Geobits

It's clear from that picture that he's just a pale imitation.

2

hosch250

@Bet Does this notify you?

Rainbolt

If you hover over the message it highlights him

hosch250

I think it was probably the two @BetaDecay's that I had in the line.

Yup.

Hmm.

Geobits

You only need 3 letters for a ping, @hos

hosch250

18:12

Oh, I see.

Beta Decay

Has my avatar updated yet? I wanted to get first dibs on the b :)

Martin Büttner

@BetaDecay 3 characters is enough

Geobits

@hosch How is your sandbox sudoku different from this non-guessing one?

hosch250

Here I am with the H.

That allows brute force.

Geobits

(beside being fastest code instead of golf)

hosch250

18:16

It is code golf, mine is fastest code.

Mine does not allow brute force - I am more interested in the different algorithms people use.

Geobits

That one doesn't allow brute force either, see comment: codegolf.stackexchange.com/questions/355/…

hosch250

OK.

Martin Büttner

Hmm... I just received an announcer badge, for a link to this question ... but a) I don't recall posting a link to the question anywhere, and b) I definitely haven't posted a link anywhere off-site, and afaik if the referrer is SE itself, views aren't counted towards the total

hosch250

@MartinBüttner Probably from the Robbers thread.

Martin Büttner

that is the robbers thread

hosch250

18:19

Oh, it is probably a link from the Coppers thread then.

Martin Büttner

but even then... those are on the network, and all of those are answer links.

hosch250

The answer links go the the question thread though, so they probably count.

Martin Büttner

possibly

that leaves the question why they are counted in the first place

hosch250

I don't know - ask Doorknob if he knows.

Geobits

> 2012-01-10: The Announcer, Booster and Publicist badges can now be earned multiple times and they can also be earned for the same question. The time limit has also been removed. Sharing direct links to answers now also counts towards these badges.

From here

Martin Büttner

18:22

yeah

Geobits

Since you have a bajillion cracks all linked to answers, I'd be surprised if you didn't earn one :P

Martin Büttner

I think the off-site requirement might only be for gold

@Geobits I was referring to "Only clicks from outside the Stack Exchange network count towards the badge"

Geobits

Oh, yea I think that's just the gold.

Geobits

18:58

Can someone explain to me what Amazon's goal is with Echo? From what I can tell, it doesn't really do anything that my phone can't. The only thing I really see is that it has better speakers. Oh, and it seems better at taking up space also.

hosch250

Make money by selling junk.

I've never seen Amazon software that wasn't riddled with bugs.

Why should their other products be better?

Geobits

Kindles are amazing. But yea, lately...

By Kindle I mean the e-ink reader type, not the shitty tablets.

hosch250

My Kindle software looked awful and crashed.

Geobits

I've had mine for a few years without problems. Still gets weeks of battery life.

hosch250

Their Fire phone sounds like it could be interesting if it was made by MS or even Apple, but it has terrible reviews.

Oh, I don't have a device - just the software on Windows to read Kindles.

Geobits

19:02

Oh, I don't know about the software. I mean the devices themselves are great.

hosch250

OK.

BTW, do you have a Spotify?

Geobits

Yep

hosch250

I'll make one if they have they music I like.

I need to ask my sister to check for me.

Beta Decay

19:14

Wow, I finally managed to get my avatar to update across the whole SE...

hosch250

I don't think mine did.

Up, just did.

Beta Decay

Yeah, yours has just

hosch250

Here is a big B for you: ih2.redbubble.net/image.12148403.5491/flat,550x550,075,f.jpg

This is where I got my H.

We should get a bunch of people and write "The Nineteenth Byte".

Martin Büttner

we almost never get 19 people in here

(17, unless you want the spaces, too)

hosch250

We would need to collude.

The spaces would be nice too.

OK, everyone, you need to go verify your status in the chatroom or you account will be terminated :)

Once here, we could explain what we want.

We actually have 16 right now, and several people have popped in and out.

Geobits

19:27

We have two users participating right now, and their avatars don't even match up. Good luck with 19 :P

hosch250

I lost my other avatar.

Beta Decay

Hm maybe you could try and reproduce it on MS Paint? :P

hosch250

I don't have it anywhere.

VisualMelon

you can have it regenerated, or what not, I made sure to check when I changed mine

hosch250

I had a custom one - the one it gave me is hideous.

VisualMelon

19:31

ah, I see

was it the one with the 8 hour-glass shapes?

hosch250

I actually found it in my recycle bin,

Not very large though. From a screenshot.

Beta Decay

Ahh. You could maybe sharpen that up or something...

hosch250

Maybe.

It isn't as good as it was, but...

OK, refresh me.

We need to get it so we can refresh our images ourselves.

How do you like it?

Lunch time. See ya.

Beta Decay

19:47

Lunch? Which country are you in?

Rainbolt

@hosch250 Free site, no ads, hundreds of users refreshing their avatar all day = probably asking too much

@BetaDecay If he eats lunch around noon, then he's on the west coast of the USA or Canada

Beta Decay

@Rainbolt Ohh... BTW I can't tell you and @Geobits apart without looking properly..

Geobits

Weird. Normally when I get pinged it's because someone's talking to me, not about me. I guess no response is needed.

Rainbolt

@BetaDecay Who is @Geobits?

Beta Decay

@Rainbolt I have no idea who @Geobits is...

Geobits

20:02

I'm about to write a script that appends both of your names to every message I send.

Rainbolt

There goes the avatar again

Beta Decay

Hahah mine should change to the emblem of the Klingon Empire at some point..

Rainbolt

I just had a funny idea but it might end up being slightly offensive

I should arrange scrabble letters to read "ITCH"

That way hosch and I spell Hitch!

Geobits

Yea... I'm sure your target is the H :P

Rainbolt

I just zoomed in with ctrl + + and my avatar is way clearer than yours

Why is my copy of your avatar so much clearer?

Beta Decay

20:07

@Rainbolt Where did you get Geobits' avatar from?

Rainbolt

His profile

Geobits

Mine was uploaded to gravatar at 400x400, so it's probably just bad sampling on their part.

Rainbolt

I'm on the left in the image below. Geobits is on the right.

@Geobits I just figured that my copy of your bad sampling would also be bad sampling.

Beta Decay

What did you do when you flipped it then?

Geobits

Depends. They might do an okay job shrinking it to profile size, but suck for chat size. If it's gravatar that does the sampling on the back end, yours (on imgur, right?) might handle that better.

Rainbolt

20:10

Open in paint, click "Flip horizontally", click save

Not imgur

Straight from my pc after I flipped it

Geobits

Right but I believe SE uses imgur.

hosch250

@BetaDecay I am in MN.

We ate lunch way late today.

Did any of you see my new avatar yet?

Rainbolt

The H4?

hosch250

No, the CHECKMATE.

Rainbolt

@BetaDecay's just changed

hosch250

20:14

Mine hasn't.

Beta Decay

@Rainbolt What d'ya think? :D

FryAmTheEggman

It did on your profile, chat takes longer for some bizarre reason..

Geobits

I think I'm about due for an avatar change anyway. Been using this one for almost five years now.

hosch250

I know.

Here goes!

Halfway, that is.

It changed my picture by the typing box.

Gone!

Trying to decide if it will be worth it to give this a bounty:

Q: Graphical Representation of Koch Snowflake

Generate a Koch Snowflake A Koch snowflake is a triangle that for each n, another equilateral point is added in the middle of each side: http://en.wikipedia.org/wiki/Koch_snowflake#Properties We already had a kolmogrov-complexity Koch Snowflake challenge for n=4. The new challenge is to draw ...

Beta Decay

I'm working on my solution now..

hosch250

20:20

OK.

I don't know the turtle library, so I can't be of any help.

I would be of very little help either way (as Sp3000, grc, and FryAmTheEggman could testify).

Martin Büttner

@PeterTaylor didn't we have this yesterday?

Beta Decay

@hosch250 Yeah.. I tried Falko's tips but they didn't really work... :/

hosch250

@BetaDecay It appears to do the angles right still, it just doesn't draw the lines.

It just sits there and spins around a single point (although you probably know this).

Beta Decay

Yeah, just fixed it :)

It's a bit longer though

hosch250

Nice. The image is much smaller now.

I need to walk my dog now. Have fun!

Beta Decay

20:33

Yeah. Saves a byte instead of 30. Also fits on the page for n=10 as well

See you!

Rainbolt

20:49

@BetaDecay I like it. Did you make it?

durron597

20:59

anyone given my Java cops and robbers a try? @Geobits?

FryAmTheEggman

@BetaDecay Ok, I've decided to stop littering your post with comments. [0,9/b]["F"==j] could be used instead of the other ternary.

Actually make that [0,9/b]["G">j]

Also I seem to have dyslexia'ed my first gold. It should be ~- not -~

Beta Decay

21:17

@FryAmTheEggman Won't both work though?

Also, how will [0,9/b]["G">j] work? There aren't any Gs...

FryAmTheEggman

No, one is equivalent to +1 one is -1

"F" is less than "G", but both "R" and "L" are greater than "G"

You can also change the "R"==j to "Q"<j

Rainbolt

One of our SQL gurus has checked in changesets today titled
"Removed deadlocks"
"Removed dreadlocks"
"Dreadlocks more of em"
"So many dreadlocks"

The bug he's working on has been reopened three times

Beta Decay

@FryAmTheEggman How on earth does that work?

xnor

it's a lexicographical comparison

FryAmTheEggman

The comparison or the ~- thing?

xnor

21:25

by the way, [0,9/b]["G">j]is shorted as 9/b*("G">j)

FryAmTheEggman

Why is being good at maths so good for golf? ;p

xnor

check out my tip on these kinds of conditionals: codegolf.stackexchange.com/a/40795/20260

hosch250

21:41

@Rainbolt I am studying "dreadlocks" as he called them.

I wish I could get a bit of practice in with C++ or C# sometime.

Also studying how a processor works (I actually am studying a sort of Java processor thing our professor made) and memory management.

xnor

what do you call the Python feature that 1<3<5 evaluates the and of both conditionals?

i'm trying to find a reference to exactly for what things it works

hosch250

Chained conditions?

Martin Büttner

chained comparisons

hosch250

OK.

xnor

thanks, both of those point to the right thing on Google, but I still can't find a source for exactly which binary operators are supported

does anyone happen to know?

can i do any chain of comparisons, in, is, is not, etc?

hosch250

21:49

Yes, as long as you know what you are doing.

Some of them have higher priority...

xnor

which ones?

hosch250

I think AND is higher than OR offhand.

There should be a list somewhere.

* and / are higher than + and -

I don't remember which group has %

Here is a webpage that may help: tutorialspoint.com/python/operators_precedence_example.htm

xnor

ok, i see, but do any break chained connectives

2 < 3 in [3] > [] happily gives True

but 2 < 3 in [3] > [] is not False gives False

hosch250

Try (2 < 3 in [3] > []) is not False

Rainbolt

Why is it that Java lets you BE a thread, while C# only lets you HAVE a thread?

xnor

21:52

(2 < 3 in [3] > []) is not False gives True

hosch250

Which version are you using?

Python 3 gives true for this: 2 < 3 in [3] > [] is not False

Rainbolt

Who said we rarely get 13 people in here? We have 15 now.

xnor

@hosch250 oops, you're right, I miscopied

hosch250

@Rainbolt 17

xnor

so do we have any example of things that don't chain?

Doorknob

21:54

@Rainbolt Must resist urge to kick everyone...

hosch250

Also, how can you be a thread in Java?

I never got that far, and I'm not sure I want to.

Do you mean the process is run in the context of a thread instead of the thread being in a process?

I know that is an experimental feature being studied by some people (not sure which language).

@Rainbolt ?

Quincunx

Ugh, google calculator isn't working with this wifi. That's my most-used calculator :-(

hosch250

Use the calculator on your computer.

Or try Bing.

Just search sqrt(9) or whatever.

Quincunx

I really dislike my computer's calculator, except for doing things with hexadecimal/binary. I just pulled out my scientific calculator, that's it. But now I have to manually translate km/hr to m/s; I'm usually lazy

(and plug into google instead)

hosch250

My TI 36XII has a conversion function.

@Quincunx Try this: bing.com/search?q=9+km%2Fh+to+m%2Fs&form=MOZSBR

Rainbolt

22:05

@hosch250 You can inherit from Thread in Java. You can also have a Thread.

Quincunx

But why bring a big CAS calculator to school when I can just bring my scientific? I already computed it. Don't worry

hosch250

OK.

OK, that makes sense.

I can see why C# doesn't have that, but I wonder why at the same time.

Rainbolt

C# Thread class is sealed. Can't be inherited :(

Quincunx

@Rainbolt From what I understand, it's bad practice to extend Thread, rather, you should implement Runnable.

hosch250

Quincunx is probably right.

Rainbolt

22:08

Look at the ominous comment from alex zhevzhik on this post

Quincunx

I bet the problem with the wifi is that it is library wifi and I'm using Spotify at the same time. Also, the wifi tends to get bad around this time

FryAmTheEggman

@xnor See the doc

xnor

thanks, that's exactly what i was looking for

so it is in fact exactly the operators i said

FryAmTheEggman

I believe so

in, not in, is, is not, <, <=, >, >=, <>, !=, == Should all chain

Quincunx

Heh heh, I just read Martin's starred post about reverted votes. I was one of those users :-). Now instead of every post being voted on, none of the posts have votes.

Peter Taylor

22:16

@MartinBüttner Sorry, have what?

Quincunx

No wait, the vote markers just weren't showing for some strange reason. Now they're all there.

xnor

22:30

btw, quincunx, thanks for the bounty on the rotating rectangle of code problem

i'm glad my answer makes you so happy

Quincunx

You're welcome. Honestly, I was just going through my answers, and discovered that mine wasn't accepted which meant there was a shorter one, so I went to investigate. I'm happy that someone was able to come up with a shorter one.

Martin Büttner

@PeterTaylor Sorry, I meant to include a link... there was a question about getting the next number with the same number of bits set

Peter Taylor

Yes, I saw it (and your link to my answer)

I'm wondering whether it might be useful for Suboptimus Prime's answer to Lembit's latest question, but I suspect that it wouldn't make much difference. At least, not unless it's greyified.

Quincunx

22:51

That horrible moment where the thing you are plugging into your calculator is too long to plug into your calculator.

hosch250

Mine supports 70-some characters.

Never had anything too long.

Quincunx

Yeah, it supports a lot of characters in the input. But this thing I'm trying to plug in is huge (physics homework, what do you expect?)

hosch250

Ouch. I usually split those up into little ones.

That way, I can find my mistake easier.

Quincunx

Yeah, but they want us to have a symbolic solution. And I used the quadratic formula (which hopefully is right), so with everything being symbolic inside the quadratic formula, it got huge.

hosch250

OK.

Quincunx

22:57

And I didn't want to split up the computations. Looks like I'll need to though

It's like 150 characters long...

hosch250

Woah.

Quincunx

I'll store the individual parts of the quadratic formula into memory (A, B, C), then just input the quadratic formula. That should work.

Martin Büttner

Mathematica...

(or at least Wolfram Alpha)

Quincunx

Too long for wolfram alpha

I'm betting I made a mistake, since I got a complex result. And when I flipped the one sign that would do that, I got a really small number. Oh well, I'll just finish this homework later.

hosch250

23:22

This has to be ridiculously easy: ""((((()))))....abefiilllmnnprrssttuz

I'm not getting it though.

It only uses keywords and built-in functions.

And functions that are "string".func()

433 is prime, if that helps.

Martin Büttner

@hosch250 language?

hosch250

Python.

Martin Büttner

what's it printing? 433?

hosch250

Yup.

It might have print()

Martin Büttner

Python 2 or 3?

hosch250

23:28

3

Martin Büttner

k

let's see

hosch250

if, str, min, zfill

Martin Büttner

int

hosch250

as, assert, elif

in, is, pass

raise, return

Martin Büttner

no colons though

hosch250

23:31

abs, all, bin

filter, iter, len, list, map, min, print

repr, set, str, sum, super, tuple, zip

I think it might have sum

Martin Büttner

well I don't know enough about python's built-ins to be of much help here, I think

hosch250

isalnum, isprintable

istitle, title

lstrip

rsplit, rstrip, split, splitlines

strip, translate, and zfill

I think this is it.

Martin Büttner

the thing is that some of them probably go into the string to give it some initial length

hosch250

That would probably be zfill.

That adds '0's to a string up to a certain length

Like this: "string".zfill(number)

Martin Büttner

yeah, but you gotta get a number somehow, right?

hosch250

23:39

Right.

Typically, you would use ord or that.

There is no o or d though.

You could use .zfill(len(something))

I doubt that would work though.

xnor
