@trichoplax I think you didn't say anywhere that it would be a royal battle, and not 1on1s

By the way, how do you intend to "steal" food?

@Katenkyo The only food stealing that is possible is a queen taking food from a worker. Most of the time that is what you want - your own queen takes food from her own workers. But if an enemy queen is adjacent to one of your workers she will also take its food

In the overview:

"All players are competing in one large arena."

Do you think I should say

"All players are competing in one large arena at the same time.

Rainbolt

I left a comment on a code review and the response I got was "I haz fixored". If I approve the second code review, then "I haz fixored" will be in TFS for all of project management to see :-/

Katenkyo

Ho, yeah, my bad missed this.

@trichoplax It's great as it is, once again, I'm tired and forgetting details :/

trichoplax

@Rainbolt Will that reflect badly on you? I'm guessing the person who left it already knew it would become a permanent record?

Katenkyo

@Rainbolt haha "I haz pwned"

Rainbolt

3:07 PM

@trichoplax No, it wouldn't reflect badly on me. Chances are nobody will ever see his comment.

trichoplax

@Katenkyo I think this is a sign I need to shorten the spec - by the time you get to the end you can forget the beginning ;)

Rainbolt

Nobody looks closely at changesets unless they cause the build to fail

And if I approve a changeset that causes the build to fail, then that would look bad

Katenkyo

@trichoplax You must be right

@Rainbolt Then reject and ask him to put a serious message?

Rainbolt

I'm just being a grumpy cat today. It's been raining for over a month now almost every day, and today is the first day it actually rained on me. For an entire month it has miraculously stopped raining at exactly four points of my day: going to work, lunch, home, and dinner.

trichoplax

That's a reason to be happy, surely - once out of a month is a pretty good record...

Wait, dinner? Does that mean you go out every day for your evening meal?

Rainbolt

3:11 PM

I go to the store four times a week and I eat out the other three.

I'm pretty weird about leaving raw meat in the fridge

trichoplax

Ah I see

Katenkyo

@Rainbolt then leave it in the freezer

trichoplax

A great way to keep meat fresh is not to kill it until you need it

Rainbolt

@Katenkyo I should do that

trichoplax

Vegetarian meals are also a great work around

Katenkyo

3:13 PM

well, anyway, leaving for now, have to go to the store :)

trichoplax

Have fun

Katenkyo

@Rainbolt It's always pleasant to not have to move to eat :)

@trichoplax I love so much meat that it would be harsh :/

Rainbolt

I wonder if I would get home and think "I can wait for this to thaw or I can eat out. Hmmmmm...."

I have a pretty low willpower when it comes to cooking. I will find reasons not to

trichoplax

Maybe you need something fairly thin that you can just cook from frozen

Vioz-

I personally keep a herd of cows in my backyard so I always have fresh meat

Rainbolt

3:15 PM

My dad has about 950 of them these days (cows that is)

trichoplax

@Vioz- You must have a pretty big family to get through a whole cow while it's still fresh...

Vioz-

Big in terms of lineage or size?

trichoplax

I guess either could work

Vioz-

In reality my backyard probably has 150sqft of grass space

I don't think that qualifies as suitable even for 1 cow

Geobits

That's basically a smallish bedroom.

The good thing about cows is that the space they need grows sublinearly (just with a large initial constant factor). Correct me if I'm wrong, @Rainbolt.

Rainbolt

3:27 PM

@Geobits Assuming that about half of your land is covered in trees or other non-grassy pastures, I'm pretty sure that each cow needs about 1 acre.

When you add in potential drought and the need to separate pastures by pregnant, newborn and nursing, cows with bulls on them (breeding pasture), etc., then you lose some efficiency.

Because if you have exactly enough, you won't have enough when a drought comes

Oh, and the lakes. You can't have a pasture without water

Vioz-

Is the 1 acre/cow a law or a general rule where you live

trichoplax

Cows just hate the metric system

Rainbolt

Just a rule my dad follows. But we have so much forested land that we have 2150 acres and only 950 cattle

Most of our land is woods

Geobits

Hmm. I guess maybe it's a bit different with horses. That's my only experience raising grazing animals, and only a few of them.

Vioz-

The largest cattle station is 6 million acres and only has 17,000 cows, apparently

trichoplax

3:34 PM

Cattle station?

"All hands! Cattle stations!"

Vioz-

Anna Creek Station

Anna Creek Station is the world's largest working cattle station. It is located in the Australian state of South Australia. Its area is roughly 6,000,000 acres (24,000 km2; 9,400 sq mi) which is slightly larger than Israel. It is 1,977,000 acres (8,000 km2; 3,089 sq mi) larger than its nearest rival, Alexandria Station in the country's Northern Territory and over seven times the size of the United States' biggest ranch, King Ranch in Texas, which is 825,000 acres (3,340 km2; 1,289 sq mi). The nearest township is William Creek (which is surrounded by the Anna Creek station), but the nearest town...

Geobits

Like a train station, but a bit louder, and a bit less smelly.

Rainbolt

I love "the Australian state of South Australia"

It's so original

I guess South Africa is also a country

Vioz-

For comparison, the Sultan of Brunei's palace has 49 acres of floorspace for him (we'll pretend he's the only person who stays there).

Each cow at Anna Creek has 353 acres of groundspace

I mean, the Sultan does have a fleet of 600 Rolls-Royces, and the cows have none

Geobits

Not to mention "...an air conditioned stable for the Sultan’s 200 polo ponies..."

BrainSteel

3:50 PM

Air conditioning?!! Now it's unreasonable!

Vioz-

Apparently the Sultan also owns 134 Koenigseggs. Only 366 have ever been made, so he owns 36.6% of all Koenigseggs on the planet

My biggest question is that, if he can afford all this nice stuff, why would he own a Toyota Previa?

Dennis

I couldn't find anything on linear Diophantine equations on main or in the sandbox. Has that really not been done before?

Geobits

@Vioz- Gotta catch em all

Vioz-

Slight correction, he has 10

Yes, I can see how with that much money it would be appealing

Geobits

I don't need a Rattata, but I have one.

Vioz-

3:56 PM

I think I could get by with about $5 billion in cars

Geobits

The more sensible explanation is that they're for staff use. I don't want my servants using the luxury cars to fetch eggs.

Vioz-

There's reportedly a RR that is left running at all times for whatever purpose. Like, actually idling. 24/7.

Lembik

hi @MitchSchwartz

Vioz-

Some of his staff are paid $200,000

A WEEK

At least he's humble when it comes to his cigars, you can buy 'em for $50

Mitch Schwartz

@Lembik hi

Lembik

4:05 PM

@MitchSchwartz so.. I just want to say I still don't understand feersum's answer! :(

I feel a little dumb for it too

but it looks so simple I wonder what magic it contains

have you had any thoughts about it? Maybe the implementation can be sped as you did with j = 1 too of course

Mitch Schwartz

have you tried looking at it while doing a handstand?

i haven't thought about it, no

Lembik

yes!

(re handstand :) )

BrainSteel

Have you tried explaining it to a rubber duck?

Lembik

@BrainSteel actually no.. that is my next step

of course the author could explain it better perhaps :)

Mitch Schwartz

rubber ducks can be harsh critics. i'd go with a ceramic duck if i were you

Geobits

4:16 PM

Only if you don't ask them pointed questions. They crack under pressure.

BrainSteel

4:27 PM

@Geobits I am impressed.

Lembik

4:37 PM

@MitchSchwartz hmm... sounds tougher

@MitchSchwartz sorry to go on about this problem to you.. you seemed really interested at one point :)

@MitchSchwartz please tell me if you never want to hear of it again!

Mitch Schwartz

4:49 PM

@Lembik it's a matter of not having time to get around to everything, rather than not being interested

Lembik

@MitchSchwartz oh cool

I completely understand.. I am frustrated I have found a clear hour to study feersum's answer

aditsu

@Vioz- ok :)

Vioz-

Wow, nice!

Mitch Schwartz

5:05 PM

@Lembik for things like that, if i don't see a way to proceed after a while i'll often just work on a different problem instead (unless it's a bug finding situation)

Lembik

5:20 PM

@MitchSchwartz makes sense . I was thinking that feersum's new solution might open a door to j = 3 if I understood it

Lembik

5:41 PM

or just a really fast j = 2 :)

like you did for j = 1 so successfully

Mitch Schwartz

6:00 PM

@Lembik do you also participate on challenges as a solver sometimes?

Lembik

6:10 PM

@MitchSchwartz hardly ever sadly

I wish I had more time too!

Vioz-

7:18 PM

Quick question: right now my question has two answers of equal length. If nobody beats them in say, 6 more days, do I mark the solution as the one that was submitted first? Or is there other criteria.

Geobits

I think the normal "unspoken" tiebreaker is first submitted if nothing else is mentioned in the question.

As for Eulerians. I'm not sure.
But, there are definitely many people who are great at math than I.
About the closed formula. Yes, I saw it.

@Lembik I think I could write a formula for j=3..it will have 10 summations

Nathan Merrill

is there a reason high level languages that don't support arbitrary precision integers don't throw a runtime error when you try to add 1 to their maximum integer?

or does it make more sense to simply wrap the values?

Dennis

@PeterTaylor: I knew this had to be done before, but I didn't include orange or cents in my search terms... Anyway, my challenge is code golf, asks for a solution (not the number of solutions), forbids built-ins and is code-golf. Do you think it's sufficiently different?

Rainbolt

@NathanMerrill What do you mean by "high level languages"? I don't think all high level languages actually follow the behavior you describe.

Here's a table showing some behaviors: en.wikipedia.org/wiki/Integer_overflow#Security_ramifications

I found the IEEE spec for floating point arithmetic, but I'm having trouble finding a similar spec for integer arithmetic

All I can find in the Java Language Specification is "The integer operators do not indicate overflow or underflow in any way." It doesn't explain why

Carnegie Melon has a Java coding standard and one of the rules listed in it is to protect against underflow/overflow securecoding.cert.org/confluence/display/java/…

But again, doesn't explain why

BrainSteel

9:25 PM

Fun fact, though languages like C/Java exhibit undefined behavior (most of the time) you add one to the maximum of a signed integer value, I can personally confirm that doing (SIGNED_INT_MINIMUM)/-1 will make some C compilers, rather than allowing an overflow, violently crash and throw an EXC_ARITHMETIC. This was a difficult bug to track down.

feersum

C compilers or C programs?

Peter Taylor

@Dennis I searched for Frobenius. Will look at your sandbox post later: I'm off to bed in about two minutes.

Rainbolt

@BrainSteel Java exhibits undefined behavior?

I thought it just wrapped

Peter Taylor

@MartinBüttner, three drafts submitted to OEIS: one for A066931 and two for related sequences.

BrainSteel

@feersum The compiler doesn't crash, the program it generates does. Whoops.
