@Cerberus No. Pennsylvania has definitely had a primary already. It was April 24th. That map was updated in May.
 
But...
Are you sure that wasn't a Democratic primary?
 
Oh OK.
So people get to vote, but the delegates are not contractually bound to abide by that vote.
And that won't change until after the first voting round.
Or it would be contradictory.
 
No. The green ones specifically are unbound. There's about 1/3 of the state bound to Trump but the rest are free to vote as they like.
Or maybe that's what you mean?
 
Yes?
 
12:04 AM
South Dakota is completely unbound, so the primary just tells them who the people want them to vote for... but they can still vote for whomever they like.
 
I was only talking about the green guys in Pennsylvania, not the red ones.
 
Yes, they're unbound, even in round one.
 
Right.
And my assumption was that the green girls were not added to the totals Trump has won in the papers.
 
Yes, I would agree with that, though Jefromi makes a good point that it may depend on the publication.
 
I think I have seen graphs where a number of of delegates were labelled as unbound and not added to Trump's total.
 
12:20 AM
Probably. Anyway, I'm off. You should sleep :P
 
Sleep well!
It's still early for me.

Q: Why do chefs use salt and pepper bowl after touching raw foods

Brooke GritchWhen I see chefs on tv handling raw chicken or such and then stick their fingers in a salt bowl to seasoning them why is the salt in the bowl not contaminated too. I see this all the time on cooking shows.

Q: Is it contaminating to spice to touch it after touching raw meat?

CeleritasWhen I cook raw meat, especially chicken strips, I have it spread out on the chopping board with a few bags and containers of spice to the side. I don't actually use too many shakers for spice. Since my fingers can only hold so much spice at once, I often go back to the bag and grab some more and...

 
Huy
?
 
The old question is badly worded
the people overlooked that and answered the real, answerable question behind the bad one
now somebody posted a new question which asks the same thing as is answered in the old one
I wonder if I should close as a duplicate
technically, it is not a duplicate, as the nominal question is different
practically, they are asking the same thing
also, if I close, I would like to keep the well worded question open and not the old badly asked one
 
Huy
how bad is it really though
 
but the old one has more extensive answers
so I wonder what to do, close or let them both open
and if I close one, which one
 
Huy
I'm pretty sure I've forgotten to wash my hand very frequently in the kitchen but I'm still alive for now - not that I do it on purpose
 
9:19 AM
that doesn't matter
your spices were contaminated. "Contaminated" doesn't mean "it will make me sick".
 
Huy
ok
kinda thought it did
 
no, it just has a chance to make you sick. The chance is low.
 
Huy
oki
 
@rumtscho any chance of merging them?
 
@Stephie I could, but I don't think this will work well
if I keep the old question, I have annihilated the better one, in this case I would prefer to close the new one without merging
 
9:32 AM
Or should someone heavily edit the old one?
 
if I keep the new question, the many answers to the old one won't fit the wording of the question
Hmm, now I look at the answers of the old one again, they won't be all that bad at the new one. The TV chefs are mentioned, but the answers are not centered around them.
 
I didn't vtc (remembering the old one), because the new one asked about spices, the other about salt and pepper. There, one answer focuses on practises in pro kitchens, one on salt alone. The new one is from a different context (home cooking) and more general.
 
Hmm. I see that one answer is specifically about salt, but the old one still asked about "seasoning" which in my usage can include any spices beside salt.
 
@rumtscho very elegantly done.
 
and the salt-specific answer is not out of place on the new one.
@Stephie thanks
 
9:41 AM
Now we just need to upvote @Jefromi to adjust proportions ;-)
 
I already did
 
Me too, of course
 
So others are needed to push his answer up. I hope it still gets noticed, even being the third answer now.
 
Have to get started with lunch. Chicken Korma today. I sense an upturned nose with minor 2...
 
@Stephie how would you say "keep you in mind" in German, poilitely?
 
9:45 AM
Kontext, please?
 
I met person A at a conference and he asked if my employer does a specific service for external people
I asked B, who works at the right department at our house, if we do
B said "no, not as a service, in principle it is possible if we set up a collaboration project together with research grant etc."
this is not what A needs
so I have to write B back and say "OK, A will keep the possibility of that collaboration in mind and get in touch with you if the opportunity arises" or similar
I'm not sure how to word that mail well, it feels delicate.
 
Ich behalte sie / das Thema /... im Hinterkopf or
Ich denke an sie wenn sich was ergibt / ein Projekt aufgemacht wird / ...
Oh, sorry, writing to B.
 
yes, just to let him know that he doesn't have to start preparing for a collaboration soon
but without making him feel snubbed
> Vielen Dank für die Info. Ich habe die Information weitergegeben. Er hat im Moment kein großes neues Projekt geplant, wird aber die Möglichkeit im Kopf behalten und auf euch zukommen, wenn sich etwas in dieser Richtung ergibt.
Does it sound OK, or a bit rude?
 
Passt.
 
Danke!
 
9:59 AM
Morning.
If I make caramel by boiling condensed milk in a can, does any one know if that will freeze solid or if it will have an ice cream like "solidity" ?
texture
 
Aka dulce de leche?
No idea.
 
Indeed, dulce de leche
I don't have an ice cream machine, and want a small amount of caramel ice cream and was hoping it would just about freeze enough :)
Looks like, add a bit of double cream and it does :) epicurious.com/recipes/food/views/…
 
Seems you're good to go.
 
:)
 
10:22 AM
If you are sitting home anyway, you can use the granita method to make it creamier
pour it into a flattish tupperware, stick in the freezer
every half an hour, stir by hand, breaking up what has already solidified, then put it back

1:39 PM
So I made cabbage stew last night
and its really yummy
Plus everything was really cheap
I essentially made minimum 6 meals worth of food for like $5
Tomatoes, cabbage, with like .5lbs of chopped up pork and a can of beans
It was kind of what i had lying around. I didnt want to go grocery shopping. So im happy my random whatever I had stew turned out so tasty
 
yes, random stews can turn out great
 
2:15 PM
Excellent!
 
Jay
The weather is gorgeous outside today
 
Were you a cabbage person? I forgot whether you liked the sulphur or not.
 
Jay
About 75C but with a very nice cool breeze
 
I know Rummy doesn't.
 
Jay
@Cerberus i do like cabbage. and brussel sprout and broccoli.
 
2:16 PM
75C is a nice temperature for sous-vide.
 
Jay
Oops
 
Or custard.
 
Jay
lol i meant 75F
 
Hehe.
 
Jay
and around 25C
 
2:17 PM
It was nice of you to at least use the C.
25C is nice.
If you can stay in the shade.
 
Jay
i even used google to convert the 75F to C but forgot to use the 25
 
Aww.
You tried.
That's what counts.
 
Jay
Theres a nice cool breeze so its perfect
 
That helps.
And dry air.
It's 14C here but I'm all sticky because it's so humid.
 
Jay
thats so chilly
 
2:30 PM
It's nice if you're biking or sitting in the sun...
 
Jay
2:56 PM
really? the temperature feels a lot colder when you are biking
or at least initially
In any case, we have very different temperature preferences :P
 
@Jay Yes, initially.
But then the exercise kicks in...
@Jay When I'm sitting in someone's shaded garden, 25C is perfect for me as well!
 
Jay
3:42 PM
im excited for lunch
so i can eat more of my cabbage stew!
hehe
 
4:10 PM
Haha.
My life is sometimes equally exciting.

Q: How to create looped output with knitr?

rumtschoIn my thesis, I have found 79 different concepts I need to describe in detail in the appendix. I used R for the analysis, and I want to use knitr for creating that appendix. Each description follows the same basic "template" filled with the values for one concept. The template is not overly com...

I very much hope I'm wrong and that there is a better way
 
A&C is too much on the brain :P I can't see "knitr" without thinking knitting.
 
If I could turn in a sweater as my PhD, I would have had several titles by now
no, sweater is too easy
let's make it a hat for a bachelor's, sweater for a master's, lace shawl for PhD
 
Hmm sounds painful.
 
I would still have a bunch
on a more serious note, the knitting reference is intended
 
Can't you e.g. write a programme that simulates the input you'd need to give to Latex and execute that when needed?
 
4:48 PM
the older technology is called "Sweave"
 
Even simulate mouse clicks if needed (I have no idea how Latex works).
 
the idea is that you weave in S expressions (or R, as R is a free implementation of the proprietary language S) within LaTeX code
 
@rumtscho Interesting... so someone made a series of tech based on bastardizations of fibercraft terms?
 
so the guy who wrote the better version wanted something reminiscent of "weaving" and thought it is like "knitting"
 
But they're so completely different.
 
4:50 PM
and made it "knit-R" because it knits R code into LaTeX documents
 
Ah... now that makes more sense/
 
from the point of view of code, there is no difference if the foreign "matter" is knitted or weaved into it
@Cerberus that's what I'm doing, and it is hideous, and a pain to write
just think of all the possibilities to mistype stuff
or to forget to escape a backslash
 
Ah OK.
I pity you.
 
and the knitr code gets compiled to LaTeX code by knitr, which then gets compiled separately by a LaTeX compiler to a PDF
which means that I can't create a loop in LaTeX (which would create some WTFs on its own, but not as many) and fill it in with R expressions
 
That must be annoying.
 
 
1 hour later…
6:24 PM
Argh! Now I really don't know whether to laugh or cry or what.
The coding brought me into a blind alley
 
Jay
its not impossible to both cry and laugh
but i guess thats not really helpful
 
an expression which is output by standard R just disappears when it is output by knitr into LaTeX without throwing any errors
so I did what any frustrated grad student does: checked my mails.
 
Oh, dear!
Haha.
 
My prof wrote back that she has read the chapter I sent her yesterday
 
Jay
When i need a "moment" i go on a pee break
 
6:26 PM
it is a chapter describing basically all the work I did in the last two years
it was a systematic literature study. I had to go over the same 136 articles over and over again, extracting data, analysing it, noticing that there are flaws in my analysis, devising a different method, realizing that I need some other data for it, back to extracting...
so now it is complete, and I described it
it had two research questions
1) which concepts have been linked to satisfaction
for example, in some of these studies the authors calculate the correlation between usability and satisfaction, others calculate the correlation between learnability and satisfaction, and so on
I found 79 such concepts
and then 2) how strong is the link of each of those concepts to satisfaction
the second one is known as a meta analysis
if there are three studies which find a strong link between learnability and satisfaction, I can say that there is a strong link
but mostly there are 10 studies, of which 3 find a weak link, 5 find a medium, and 2 find a strong one, and I spent ages devising a way to decide what to do with those cases
anyway, that's complete, and I described it
and there comes her offhand comment
"It would be interesting in the discussion to say why these concepts have a strong or a weak relationship to satisfaction"
WTFFFF!!!!!
How should I know why they have a strong or a weak link
 
@rumtscho Is she asking for a conclusion with some speculations about causes?
 
@Jefromi I don't know, she only wrote this one sentence. I will ask her what she means.
But I don't even have enough to go on for a speculation
also, I'd really hate to bring in random speculations into the discussion
 
Perhaps she is just asking for an hypothesis.
Speculation, yes.
But the discussion comes at the end, right?
 
really, if it were obvious that the weakly linked concepts are not good for measuring satisfaction, those people wouldn't have studied them in conjunction with satisfaction
 
So it's basically in addition to your main research.
 
6:33 PM
the discussion is not an addition, it is a summary of "what did we learn"
 
But you can pepper it with a few bits of speculation?
Without basing them on your research.
 
I know I've seen speculation in conclusions before, in the vein of "some parting thoughts, maybe directions for further investigation, etc".
 
I have no good basis for speculation
 
Maybe you don't need a basis.
 
yes, the "directions for further investigation" thing is common
 
6:34 PM
And it's often without much solid basis... but it's also nicely isolated.
 
but they are not explanations gotten out of thin air
 
Can you think of any causes for weak or strong relationships?
 
@Cerberus no, I can't
 
I'd say out of thin air is OK in this situation?
I suppose 79 concepts is way too much to be able to speculate about them all.
 
@rumtscho, do you happen to know the English term for "Hexenstich"?
 
6:36 PM
@Stephie if I do, I don't know that I do
 
@Stephie Cross stitch maybe? I see some images that are similar for both search terms in Google Images.
 
@Cerberus that's one of the problems
the other is that in my view, filling my thesis with unsubstantiated speculations is worse than offering no explanations at all
especially when my research goal wasn't to find explanations
 
But it's not filling?
It's just an afterthought.
 
I totally agree about not putting speculation in the middle of things, and not speculating about a million things, but I do think you might have a fairly high standard for what constitutes substantiation for speculation :)
 
I mean, imagine your standard metaanalysis
 
6:38 PM
@Jefromi Rummy is indeed very thorough and precise!
 
maybe the one which finds that Prozac isn't better than placebo (I've heard it exists, but haven't read it)
Could you imagine the people there starting to speculate about the reasons why Prozac doesn't work?
 
What is the correlation between learnability and satisfaction? Is it positive, negative? Strong, weak?
 
it's ridiculous
 
I think people do just that in articles?
 
@Cerberus nope. It's a stitch to fix two fabrics slightly elastic and almost invisibley. And you stitch against the general sewing direction.
Whatever, more googling later.
 
6:39 PM
@Stephie Oh, I see.
Sounds complicated.
But useful.
 
@Cerberus OK, let's see. The first concept I have on my list is "accessibility". Defined as "refers to the speed of access and availability of the Web site at all times".
 
I guess you might have some basis when there's weak correlation because your sources might've mentioned causes of noise, confounding factors, etc?
 
What would your speculation be for its relationship strength to satisfaction?
@Jefromi I am working with 800+ separate correlations. I don't have the time to look into each one separately and see if the authors mentioned causes of noise or similar.
 
Sure, didn't mean you should necessarily do it, just that it might in principle be possible in some cases.
 
People are psychologically disinclined to enjoy waiting, so a fast website is more satisfactory. And a lack of availability means positive expectations do not come true, so more disappointment and less satisfaction.
These are fairly universal human characteristics, so a strong link is perhaps not unexpected.
What I would find hard to describe, though, is the relation between my speculation and Rummy's satisfaction!
 
6:44 PM
@Cerberus well yes, that's just an explanation of why it would have some link to satisfaction at all. But there are such reasons for every single concept on my list, including the ones which turned out to not be related to satisfaction.
 
Okay, and can you think of counter-arguments for the weak ones?
 
So thinking up such explanations for the positively related ones is useless, because they obviously don't have to be true.
 
What is an example of a weak one?
 
user participation
 
Y'all aren't exactly having the same conversation, I don't think.
 
6:45 PM
@rumtscho What does that mean?
@Jefromi We are engaging in a Socratic dialogue.
 
Yes, you can speculate about absolutely any of what rumtscho's found, but she doesn't think that's worth doing.
 
it means the degree to which users were involved in creating the software, like asking them "what features would you like to see"
 
Ah, OK.
 
@Cerberus you are engaging in a socratic dialogue; I'm not sure rumtscho needs a demonstration that you can speculate about everything. Could be wrong, though.
 
I can surely come up with some reason why it doesn't matter much for the final satisfaction.
But the problem is that, had it been that learnability has a weak link to satisfaction and user participation a strong one, I could have come up with speculations for that constellation too.
 
6:48 PM
Well, then you could perhaps offer some counter-arguments, such as: 1. there is some time in between the involvement and actually using the end result, and that time may dull the positive link. 2. There is a chance that they won't like their own contribution as much as they expected, which would be extra disappointing, because it is an unfulfilled positive expectation.
 
so my speculations have zero explanatiory value.
 
@rumtscho Yes, but isn't that why it's speculation?
 
I am OK with educated guesses.
 
But speculation has even lower standards.
Perhaps none at all.
 
But if there is good evidence that the educated guesses are not consistent with reality, then I prefer to not make any.
 
6:49 PM
Because they might be wrong?
 
They are worse than wrong - they are misleading.
 
Oh, wait, you said evidence.
 
They seem like nice plausible explanations, and invite people to believe in them
 
Yes, okay, but what if there is no evidence one way or another?
That is true: it is important that don't treat speculation as more than it is.
 
If there is no evidence, then there should be no conclusions made based on the missing evidence
 
6:52 PM
But what if you explicitly say that you're speculating? Then readers are cautioned not to believe it, but just consider it "food for thought".
 
psychologically, the caution doesn't matter
 
It may matter less than it should.
 
you remember statements you read much stronger than modifiers about their truth value
 
However, isn't the food for thought worth something?
 
and from a scientific point of view, they are worthless at best - if the readers are very scrupolous about not taking them as true
 
6:53 PM
There may be a lower standard for speculation in conclusions of a paper than for the claims in the paper itself, but it's not a "zero" standard either.
 
but harmful in other cases - if readers forget that they are completely random
 
@rumtscho They may inspire others to conduct new research in order to test the speculated cause?
 
the presence of the link itself should be enough inspiration
 
I don't know: I think I would find speculation about the mechanism behind the link extra inspiring.
 
the creation of a new hypothesis worth testing requires much more than a bad speculation, and it should be done by the person who wants to do the test, in the first step of their research, using more sources than just my information that the link exists.
 
6:55 PM
Then again, I won't be researching in your field.
 
Look, if there was any sign that my speculation is worth something, I would do it.
 
Yes, it requires more, but that doesn't mean inspiration doesn't work or has no part in the emergence of an hypothesis.
So why do you think your professor wants the speculation?
 
Maybe the professor doesn't even want the speculation, she's just expressing curiosity?
 
I think she wants it because she wants to know the reasons
 
and so "I don't really have that information, neither do the papers I reviewed" would be a fair response.
 
6:57 PM
If I could list such reasons, my results would be much more likely to be accepted for publication in a good journal
She really said that she expects me to include such reasons in the discussion
 
I see.
 
hm. Just unreasonably high expectations, perhaps?
 
she is correct that it would make for a much more interesting article
 
But would she still be interested in those reasons if they were baseless speculation?
 
@Jefromi Yes. This is typical for her.
I mean, it is a recurrent problem here, because I also have very high expectations of myself
just today talked about it with my customer (who has been advisor to many PhD students myself) and her advice was that I should learn to cut corners and just produce a deliverable study instead of making every last detail perfect
 
7:00 PM
She's probably right...but it's easier said than done.
 
but within my PhD-writing department, we all know that our professor is the worse perfectionist.
 
How about if you offered two contradictory speculations for each link that you mention?
 
Come up with 160 separate speculations? This would take me weeks, and I don't have that time. Or the space to write them up in the dissertation.
 
There is a weak link between x and statisfaction. On the one hand, that might perhaps be expected based on speculation that p. On the other hand, one might expect the opposite based on q.
 
and it would, in my view, severely reduce the quality of the thesis.
 
7:03 PM
@rumtscho Oh, no, just treat two or three salient links.
 
I don't see any of them as salient. They are all the same to me.
 
If you offer two mutually exclusive speculative 'causes', then people can't just read it as if you really thought one cause or the other was a justified explanation.
@rumtscho Hmm perhaps that is something you could talk about with your professor: there is no space or time available for speculation about each link. Do you should I should pick two or three? Which ones do you think are most salient?
Two opposing explanations could also serve as a nice illustration of the uselessness of speculation.
 
The best I can expect of this is for my professor to understand better why it is nonsense. In the worst case, she will still want me to include it.
jinx.
 
Hah.
 
@rumtscho I guess the two things that might be naively interesting would be strongest correlations, and weakest correlations for things that are routinely prioritized. But I still agree that it's a little much to expect something like your work to generate a ton of new knowledge about underlying reasons like that.
 
7:07 PM
I purposefully don't use "strongest correlations" and "weakest correlations"
 
never mind then!
 
it is inadmissible to do numerical comparisons between different psychometric studies, the measurements are just not that precise
so I very early divide the effects into "strong", "medium", "weak" and "no clear effect" and leave them at that
 
And a strong effect can be positive or negative?
 
There are 22 concepts in "strong" and 2 in "none", which is still too much.
 
Or do you have no negative effects?
 
7:09 PM
in principle yes, in practice all are positive.
 
OK.
Are there any effects that are strong even though the average person might not expect a strong effect there?
 
In reality, I am not even claiming that the categorization is correct in principle
 
Understandable.
 
I have a model with 80 variables and 136 data points - that would be the mother of all multiple testing analyses!
 
Presumably people tend to come up with concepts they think will be positive for users, so as long as their intuitions aren't totally off, they won't end up with negative correlations?
 
7:11 PM
"Unexpected" may be salient.
 
So I don't do hypothesis testing, I only do descriptive statistics on the available data set, with a bit of a sensitivity analysis
@Jefromi yes, that's a speculation I did include, to explain the absence of negative correlations.
this is an example of a speculation I am comfortable with, it feels reasonable and I cannot come up with equally good speculations for the opposite effect.
@Cerberus yes, I thought of that, this would be the two concepts without no effect at all.
 
Ah, OK.
You could do those.
 
Still, I don't think I can come up with a good speculation for them - my gut feeling is that they should have an effect on satisfaction, so any speculations which try to explain why they didn't have it are unsatisfactory.
 
What are the two concepts?
 
user participation is the one, effort is the other
as in, "the amount of effort it takes to use the system"
 
7:16 PM
Hmm odd.
How about the delay between creating the software and actually using it once it's finished?
 
What do you mean by "odd"?
that your gut feeling is also that they should have some link to satisfaction?
 
Odd as in, I would have expected a positive correlation too.
Yes.
 
because that is true of all 79 concepts on the list
 
I'm sure.
 
More effort as long as it works means more satisfaction! You did something hard, good job! But if it doesn't pay off then it means more frustration :(
 
7:18 PM
But that doesn't make the lack in these two expected.
 
if people think that a concept won't have a link to satisfaction, they don't make a correlation study linking it to satisfaction in the first place.
 
Of course.
@Jefromi Sounds good to me.
 
It doesn't matter which ones fall into the "no effect" category, it would have been unexpected for any of them.
 
@rumtscho So those people researchers expected a link. And I would probably share their expectation. So it's odd when my and their expectation doesn't come true.
@rumtscho So the expected result would be that all concepts have a clear positive effect.
Of course it's not "odd" on a deeper level.
Because expectations are often not fulfilled.
 
Yes, for each of the concepts in isolation, it is odd that they don't have a positive effect on satisfaction.
 
7:20 PM
Yeah.
That's what I meant.
 
But it is not odd that it is those two which were measured to have no effect and not some other two.
 
Indeed not.
 
In reality, I have no explanation why some of the concepts on the list were measured to have a better relationship to satisfaction than others.
 
Of course.
 
7:34 PM
<Sigh.>
 
Hi Stephie!
 
Hi Catija!
 
Feeling better?
 
Sigh? Your chicken korma stays there uneaten and your child runs around hungry?
 
Hi @Catija!
 
7:34 PM
@Jefromi HI!
So many serious discussions in here these last two days :D
 
I must be a bad influence then, I return from vacation and suddenly the room turns serious :)
 
@rumtscho nope, wonder of wonders: she ate one piece of meat and some sauce. (And an extra serving of plain rice.
The sigh was deep satisfaction: A sandwich with salad leaves and radishes picked from the balcony just minutes ago.
 
@rumtscho Not at all! We've also had plenty of silly conversations.
 
@Cerberus Yeah... I'm blaming Cerberus ;)
 
growls
 
7:38 PM
Crap, forgot about all the teeth... nice doggie?
 
Wait, for what?
 
Have a biscuit?... or three?
 
For the silly conversations or the serious ones?
 
@Cerberus <offers a bite of sandwich>
 
Thank you, both!
nibbles
Who am I kidding... devours
 
7:42 PM
@rumtscho ha, and for running around hungry: she knows how to fix herself a bowl of cereal...
 
all is settled then
I have much understanding for her
used to be a very picky eater myself as a child
(although I at least had the excuse of growing up with a mother who didn't cook well)
 
And now you're no longer picky?
 
@rumtscho She might claim the same...
 
I didn't starve, and I have less weight management problems than my former classmates who were required to finished their plates
I am still picky about some stuff, but eat much more than as a child, both in relative and absolute terms
 
I see.
 
7:46 PM
@Stephie I suspect it would be much less substantiated than in my case
 
Oh, gosh, the old "finish your plate" battle. We put our foot down with the grandparents nine years ago and repeated it occasionally. Now the kids remind them themselves.
 
You are focusing on details of food quality my mother wouldn't have noticed if they bit her in the tushy
