Soondubu victory

Katara and I are in a virtuous cycle where she thinks of some food she wants to eat and then asks me to cook it, I scratch my head and say "Well, I never did, but I could try", and then I do, and she tells me it was really good. This time she suggested I should make soondubu jjigae (순두부찌개), which is a Korean stew that features very soft tofu. (“Dubu” (두부) is tofu, and “soon dubu” is soft tofu.)

I did it and it came out good, everyone was happy and told me how great I am. Cooking for my family makes me feel like a good dad and husband. Hey, look, I am doing my job! I love when I do my job.

Soondubu in the
bot on the range.  The  pot is dark-glazed heavy earthenware.  The
soondubu is a dark-red soup (from the chili paste) full of floating
pieces of white dubu and green-edged zucchini.

I thought maybe soondubu would be one of those things where you can make it at home with endless toil but in the end you have a product that is almost as good as the $6.95 version you could get from the place downstairs. But it was actually pretty easy. Korean cuisine is often very straightforward and this was one of those times. I approximately followed this recipe but with several changes. (One of these days I'll write a blog article about how so many people stress out about the details of recipes.) The overall method is:

Dice up some onion and garlic finely and put them in the pot with sesame oil and kochujang. Then you add the meat if you are doing that, and then about a half a cup of chopped up kimchi. Then you put in broth and you add the soondubu. Easy-peasy.

The recipe on that page called for beef but I used chicken meat in cubes because that was what Katara asked for. All the soondubu recipes I found call for kochugaru (red pepper flakes) instead of kochujang (red pepper soybean paste) but I didn't have any handy and so what?

Somewhere in the world there is some food snob who will sneer and say that Real Soondubu is always made with kochugaru, and using kochujang is totally inauthentic. But somewhere else there is someone who will say “well, my grandmother always liked to use kojujang instead”, and Grandma outranks the food snob. Also I decided this year that the whole idea of “authentic” recipes is bullshit and I am going to forget about it.

I used chicken broth out of a box. The recipe called for scallions but I think I didn't have any handy that time. The recipe called for anchovy paste but I left them out because Lorrie doesn't like the way they taste. But I put did in some thin slices of zucchini. We do have a nice Korean-style glazed earthenware pot which I cooked in and then transported directly to the table.

Everyone in my family likes soondubu and it made me really happy that they considered my first one successful.

Help me ask why you didn't just…

Regarding the phrase “why didn't you just…”, Mike Hoye has something to say that I've heard expressed similarly by several other people:

Whenever you look at a problem somebody’s been working on for a week or a month or maybe years and propose a simple, obvious solution that just happens to be the first thing that comes into your head, then you’re also making it crystal clear to people what you think of them and their work.

(Specifically, that you think they must be a blockhead for not thinking of this solution immediately.)

I think this was first pointed out to me by Andy Lester.

I think the problem here may be different than it seems. When someone says “Why don't you just (whatever)” there are at least two things they might intend:

  1. Why didn't you just use sshd? I suppose it's because you're an incompetent nitwit.

  2. Why didn't you just use sshd? I suppose it's because there's some good reason I'm not seeing. Can you please point it out?

Certainly the tech world is full of response 1. But I wonder how many people were trying to communicate response 2 and had it received as response 1 anyway? And I wonder how many times I was trying to communicate response 2 and had it received as response 1?

Mike Hoye doesn't provide any alternative phrasings, which suggests to me that he assumes that all uses of “why didn't you just” are response 1, and are meant to imply contempt. I assure you, Gentle Reader, that that is not the case.

Pondering this over the years, I have realized I honestly don't know how to express my question to make clear that I mean #2, without including a ridiculously long and pleading disclaimer before what should be a short question. Someone insecure enough to read contempt into my question will have no trouble reading it into a great many different phrasings of the question, or perhaps into any question at all. (Or so I imagine; maybe this is my own insecurities speaking.)

Can we agree that the problem is not simply with the word “just”, and that merely leaving it out does not solve the basic problem? I am not asking a rhetorical question here; can we agree? To me,

Why didn't you use sshd?

seems to suffer from all the same objections as the “just”ful version and to be subject to all the same angry responses. Is it possible the whole issue is only over a difference in the connotations of “just” in different regional variations of English? I don't think it is and I'll continue with the article assuming that it isn't and that the solution isn't as simple as removing “just”.

Let me try to ask the question in a better better way:

There must be a good reason why you didn't use sshd

I don't see why you didn't use sshd

I don't understand why you didn't use sshd

I'd like to know why you didn't use sshd

I'm not clever enough to understand why you didn't use sshd

I think the sort of person who is going to be insulted by the original version of my question will have no trouble being insulted by any of those versions, maybe interpreting them as:

There must be a good reason why you didn't use sshd. Surely it's because you're an incompetent nitwit.

I don't see why you didn't use sshd. Maybe the team you're working with is incompetent?

I don't understand why you didn't use sshd. Probably it's because you're not that smart.

I'd like to know why you didn't use sshd. Is it because there's something wrong with your brain?

I'm not clever enough to understand why you didn't use sshd. It would take a fucking genius to figure that out.

The more self-effacing I make it, the more I try to put in that I think the trouble is only in my own understanding, the more mocking and sarcastic it seems to me and the more likely I think it is to be misinterpreted. Our inner voices can be cruel. Mockery and contempt we receive once can echo again and again in our minds. It is very sad.

So folks, please help me out here. This is a real problem in my life. Every week it happens that someone is telling me what they are working on. I think of what seems like a straightforward way to proceed. I assume there must be some aspect I do not appreciate, because the person I am talking to has thought about it a lot more than I have. Aha, I have an opportunity! Sometimes it's hard to identify what it is that I don't understand, but here the gap in my understanding is clear and glaring, ready to be filled.

I want to ask them about it and gain the benefit of their expertise, just because I am interested and curious, and perhaps even because the knowledge might come in useful. But then I run into trouble. I want to ask “Why didn't you just use sshd?” with the understanding that we both agree that that would be an obvious thing to try, and that I am looking forward to hearing their well-considered reason why not.

I want to ask the question in a way that will make them smile, hold up their index finger, and say “Aha! You might think that sshd would be a good choice, but…”. And I want them to understand that I will not infer from that reply that they think I am an incompetent nitwit.

What if I were to say

I suppose sshd wasn't going to work?

Would that be safer? How about:

Naïvely, I would think that sshd would work for that

but again I think that suggests sarcasm. A colleague suggests:

So, I probably would've tried using sshd here. Would that not work out?

What to do? I'm in despair. Andy, any thoughts?

Octopuses opening jars

A while back a YouTube video was going around titled Octopus Intelligence Experiment Takes an Unexpected Turn. Someone put food in a baby bottle with a screw cap and a rubber nipple. There was a hole drilled in the bottle so that the octopus could reach in to taste the food, but it was not large enough for the food to come out or for the octopus to go in. The idea, I suppose, was that the octopus would figure out how to unscrew the cap.

The “unpexected turn” was that instead of unscrewing the cap, the octopus just ripped the entire nipple out of the bottle.

A still from the video.
The bottle is transparent plastic and the octopus, about the same
size, is behind it, with its arms wrapped around various parts of the
bottle, looking at us.  The orange screw cap that secures the nipple
in place is still screwed to the top of the bottle, but the white
rubber nipple itself is floating away. One of the octopus’s arms is
inside the bottle, entering through the large hole previously blocked
by the nipple.

I have mentioned this before but it bears repeating: this outcome should not have been an unexpected turn:

Crabs can be wrested from containers (Pieron, 1911; Schiller, 1948; Cousteau and Diole, 1973) but the results appear to be achieved by chance and there is little indication that the octopus can learn to deal with the situation more efficiently with practice. The animal approaches and struggles with the apparatus until something happens; if it learns anything as a result of its experience it is only to be more persistent and vigorous.

(Martin Wells, Octopus: Physiology and Behaviour of an Advanced Invertebrate (Springer, 1978), page 241.)

Wonders of the Internet, II

We have had two of these plastic thingies cluttering up our dish drainer for years. We didn't know what they were but we didn't want to throw them away because what if they are important?

A photograph of my hand, holding rectangular piece of white
plastic with a handle-shaped indentation on the front and two short
feet sticking out below

I got tired of them this weekend, and examined one more closely. There wasn't any indication of what it had been part of, or what it was for, but it did have the marking PART 2198768 on the back, so I handed that to The Goog.

And the result was instantaneous and unequivocal: it belongs to my refrigerator. Specifically, it goes in the back of the freezer compartment to keep food from falling down into the back and blocking the drainage path.

Partial screengrab of Google Search results.  At the top is a
link titled “Whirlpool 2198768 Read Fence”.  Then there follow some
images of the part, looking just as it does in my picture.  Then there
is a hit titled “What is the 'rear fence' and what does it do?”, and
one from Amazon offering a replacement part for sale.

Truly, we live in an age of marvels.

Wonders of the Internet, I

I suddenly wondered: was Andy Warhol ever a TV show guest star? So I asked the Goog, and the answer was better than I could have imagined: in October 1985, Andy Warhol was a guest star on The Love Boat.

According to Wikipedia, one of the subpots of the episode was “a woman avoids Warhol, wanting to forget the time she was in one of his movies.” That is a lot more plausible than many Love Boat plots!

Also starring in that episode were Milton Berle, Tom Bosley and Marion Ross, Andy Griffith, and Cloris Leachman. TV Guide named it one of the hundred greatest episodes of any TV show ever.

Wow.
