On the ritual foods of the Purim seder

Thu, 25 Feb 2021 02:05:31 GMT

Shameless self-promotion:

As we know,[1] the evening meal for Purim starts with Wacky Mac, a dish that features four pasta shapes: wheels, shells, spirals, and tubes. What is less widely known is how we are to eat this ritual item. Like the Pesach seder a month later, the meal has specific requirements and specific meanings! And like at the Pesach seder, your child should ask you to explain why this night is different from all other nights and what the laws and customs are and what they mean. It is only because of the other celebratory aspects of this holiday that in most families the child is too inebriated to ask (and the parents too inebriated to answer). So prepare yourself now, so you can both fulfill the commandment and explain it to your child.

First, we must examine the symbolism. [...]

See the full article at Judaism Codidact.

Pass the wine! :-)

P.S. For the programmers, we have this question on type systems and the use of void -- more answers welcome!

rabbinic teaching

Thu, 11 Feb 2021 02:56:45 GMT

Forwarded to me without attribution:

Rabbi Moshe Karelman, a brilliant Talmudist, and his star pupil Yeshaya are traveling to Vilna when they have to stop for the night, and pitch their tent in an empty field.

After the evening prayers Rabbi Karelman and Yeshaya retire for the evening. Some hours later, Rabbi Karelman wakes up and nudges his student. "Yeshaya, look up at the sky and tell me what you see."

"I see millions and millions of stars, Rabbi Karelman."

"And from this, what do you deduce?"

Yeshaya ponders for a minute. "Well, astronomically, this view conveys the vastness of the heavens. Chronometrically, I deduce that the time is approximately a quarter past three. Meteorologically, I suspect that we will have a beautiful day tomorrow. Theologically, I can see that God is all powerful, and that we are a small and insignificant part of His universe. What does it tell you, Rabbi Karelman?"

"It tells me that someone has stolen our tent."

I've seen variations on this before, but this is the most thorough answer from the student I've seen in any of those tellings.

taking data at face value

Fri, 21 Aug 2020 01:59:04 GMT

This is surreal. A year ago, somebody entering data on Open Street Map recorded a suburban building as being 212 stories. A backyard shed, apparently. It seems to have been an honest typo, later corrected. It happens. No big deal, right?

The error was later corrected by another openstreetmap user, BUT, in the interim, Microsoft took an export of the data and used it to build Flight Simulator 2020. The result... this incredible monolith (2/2)

The original thread where people tracked it down is hilarious.

choral part-balancing

Wed, 18 Dec 2019 02:24:52 GMT

Overheard at last night's choir party:

Director: ...And I told (another choir's director) that we have five tenors now and quite a few basses too, and she was blown away. [Context: for whatever reason, SCA choirs and maybe amateur choirs in general have a lot of trouble getting enough tenors. Our choir has about 25 members and five tenors is considered very good.]

Transgender tenor: Some of our tenors used to be sopranos.¹ She could suggest...

Other choir member: In the Debatable Choir we make tenors!

¹ Two, in fact. There is also a woman in the bass section (who hasn't undergone physical changes thus far).

talmudic humor

Sun, 14 Oct 2018 22:41:34 GMT

I heard a story the other day at minyan:

A rabbi has a long-time friend who's a gentile. One day the friend comes to him and says "Rabbi, we've been friends for decades and I've heard you talk about the talmud; will you teach me some?" The rabbi shakes his head and says "look, you aren't one of us, you haven't been trained in this, you won't think about it the way we do -- I'm sorry, but I can't teach you this". The friend persists, and the rabbi finally says "ok, tell you what -- I'll ask you a question, and if you can correctly answer it, we'll study some talmud together". The friend eagerly agrees.

The rabbi says: "Two men climbed down a chimney together. One of them was dirty and one was clean. Which one washed himself?" The friend responds "Oh that's easy. The one who was dirty washed himself."

The rabbi shakes his head. "No no, my friend. The one who was dirty looked at his friend who was clean and concluded that he was fine. The clean one looked at his dirty friend and rushed off to wash up."

"Oh please, give me another chance!" The friend pleads. "Ask me another question!"

"Ok," the rabbi says. "Two men climbed down a chimney together. One of them was dirty and one was clean. Which one washed himself?" The friend, having learned from the previous response, says "the clean one did, because he saw his dirty friend and assumed he was dirty".

The rabbi shakes his head. "No no. The dirty one looked in the mirror, saw he was dirty, and washed." "Wait," the friend objects, "you didn't say anything about a mirror!" The rabbi shrugs. "So it turned out there was a mirror."

"Let me try again," the friend begs. The rabbi sighs and asks again. "Two men climbed down a chimney together. One of them was dirty and one was clean. Which one washed himself?" The friend responds, "if there was a mirror or other reflective surface, the dirty man could see that he was dirty and he washed. Otherwise, each man looked at the other, so the clean man thought he was dirty because of what he saw and he washed."

The rabbi shakes his head once more. "How is it possible that two men come down the same chimney and one is dirty and the other is clean? Clearly this never happened!"

Some stuff has been accumulating in browser tabs. Some of it lost relevance because I waited too long (oops). Here's the rest.

This article explains the Intel problem that's going to slow your computer down soon. I don't know much about how kernels work and I understood it. I do have some computer-science background, though, so if somebody who doesn't wants to let me know if this is accessible or incoherent, please do. In terms of effects of the bug, you're going to get an OS update soon and then things will be slower because the real fix is to replace hardware, but you probably want to take the update anyway.

This infographic gives some current advice to avoid being spear-phished. It has one tip that was new to me but makes a lot of sense: if you have any doubt about an attachment but are going to open it anyway, drop it into Google Drive and open it in your browser. If it's malicious it'll attack Google's servers instead of your computer, and they have better defenses.

Sandra and Woo: what the public hears vs. what a software developer hears.

This account of one hospital's triage process for major incidents blew me away. I shared the link with someone I know in the medical profession and he said "oh, Sunrise -- they have their (stuff) together" -- they have a reputation, it appears. Link courtesy of metahacker and hakamadare.

I was one of the subject-matter experts interviewed for this study on Stack Overflow's documentation project. Horyun was an intern and was great to work with.

From siderea, the two worlds, or rubber-duck programming and modes of thinking.

The phatic and the anti-inductive doesn't summarize well, but I found it interesting. Also, I learned some new words. "Phatic" means talking for the sake of talking -- so small-talk, but not just that. Social lubricant fits in here too.

Rands on listening for managers.

From the same source as the "phatic" post, a story about zombies made me laugh a lot.

From Twitter:
Three logicians walk into a bar. The bartender says "Do you all want something to drink?"
The first logician says "I don't know."
The second logician says "I don't know."
The third logician says "Yes."

A friend shared this with me earlier today and I literally laughed out loud:

(Source)

The second-last column is about a famous Zulu leader. The last one is about walled cities under fire.

"Shaka, when the walls fell" is a key phrase in a rather unusual episode of Star Trek: The Next Generation, named "Darmok". The famous universal translator doesn't work when the Enterprise encounters these particular aliens, because their language doesn't work at the word level. They speak in what the crew calls metaphor. I've seen discussions of this over the years ("could that really work?" "improbable, because..."). The post about the Jeopardy episode links to this Atlantic article about the episode that argues that we're looking at it all wrong. I found it an interesting read.

Also, Atlantic does in-depth articles about episodes of SF shows? Who knew?

(I don't have a Trek icon. Here, have one from one of my favorite shows instead.)

I have some things collecting in tabs, so here's a hodge-podge:

First, border-crossing. You've probably heard by now that border control in the US has gotten aggressive, including demanding passwords for encrypted devices and then taking them out of view for an extended time. You don't have to give up your password, but if you don't, they can confiscate your device for weeks or months for "review". The rights you have against unreasonable search and seizure in the US are not the same as those you have at the border. While they can't deny entry to US citizens, they can to others.
It's important to know what you don't know. David Director Friedman has an interesting idea about applying economics to teaching -- specifically, grading exams.
A lot of the Rands article The New Manager Death-Spiral sounds very familiar.
We all know one of the Internet rules: don't read the comments. The parts of the net I frequent tend to be better than, say, a random sample of YouTube, which is due to a mix of conscientious participants and comment moderation. A while back I came across a comment-moderation policy described as "Victorian Sufi Buddha Lite": they require a comment to be at least two of true, necessary, and kind.
I'm not sure that philosophy applies to windshield notes, but they sure are funny.
How do we know Humpty Dumpty is an egg? The rhyme doesn't say so. Huh, I never thought about that.
Speaking of things I hadn't thought about, have you ever noticed the similarities between fantasy-adventurer settings and westerns?

purim science?

Mon, 13 Mar 2017 14:21:53 GMT

One machine-learning technique is to pit evolving neural networks against each other in cage matches and then learn from the results. This is called Generative Adversarial Networks (GANs).

At yesterday's Purim festivities somebody described the following cutting-edge research, and I remembered just enough keywords to be able to find the paper later:

Stopping GAN Violence: Generative Unadversarial Networks
Samuel Albanie, Sébastien Ehrhardt, João F. Henriques

While the costs of human violence have attracted a great deal of attention from the research community, the effects of the network-on-network (NoN) violence popularised by Generative Adversarial Networks have yet to be addressed. In this work, we quantify the financial, social, spiritual, cultural, grammatical and dermatological impact of this aggression and address the issue by proposing a more peaceful approach which we term Generative Unadversarial Networks (GUNs). Under this framework, we simultaneously train two models: a generator G that does its best to capture whichever data distribution it feels it can manage, and a motivator M that helps G to achieve its dream. Fighting is strictly verboten and both models evolve by learning to respect their differences. The framework is both theoretically and electrically grounded in game theory, and can be viewed as a winner-shares-all two-player game in which both players work as a team to achieve the best score. Experiments show that by working in harmony, the proposed model is able to claim both the moral and log-likelihood high ground. Our work builds on a rich history of carefully argued position-papers, published as anonymous YouTube comments, which prove that the optimal solution to NoN violence is more GUNs.

I haven't read the full paper yet, but on a quick skim it does not disappoint. More info.

I'm delighted to see that the paper was submitted to SIGBOVIK 2017. I had no idea that Dr. Bovik had his own SIG.

ETA: Not only was that paper submitted to SIGBOVIK, but SIGBOVIK is a real thing. How did I not know about this gem from my alma mater? (Sadly, this year's conference starts at 5PM on a Friday, which would be challenging. Maybe I'll have better luck next year.)

Purim torah!

Wed, 01 Mar 2017 02:08:11 GMT

It's the season of Purim Torah on Mi Yodeya. Here are some of my favorites:

From this year:

My answer to a question asking what Birkat Amazon is and what giving thanks after a meal has to do with amazon.com
What are we supposed to do about losing an hour of Purim this year? (I answered that one too)
Why do we shake four heretics on Sukkot? (on Sukkot we shake the "four species", different plants; the word for "species" resembles the word for heretics)
Can one go back in time to complete a minyan?

And some from past years:

Perl programming in the Torah
Surviving the zombie apocalypse
Using the Force on Shabbat
Rejecting others' friend requests on Facebook
And one I had a lot of fun answering, Why don't Jews accept Our Lord and Savior?

There are a lot more where those came from, and the season continues for about the next two weeks.
