On the ritual foods of the Purim seder

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

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

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 [profile] 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

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

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!"

link round-up

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.

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.

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.

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

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.)

purim science?

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.)

be happy; it's Adar

The month of Adar began a few days ago, which means that silliest of holidays, Purim, is coming up soon. And that means that Purim Torah -- discourse of a, shall we say, not entirely serious nature -- is in season on Mi Yodeya. Here are some of my favorites from this season so far -- recommended, and most of the ones I've selected should be broadly accessible. (Feel free to leave comments here if you need help interpreting anything.)

Why don't Jews accept Our Lord and Savior? The question (which skirts the "can Purim Torah be too heretical?" line really closely) lays out some textual "proofs". I had fun answering this.

What does Judaism think of math? Quite a variety of answers here.

What is the text of kiddush for Purim night? I've heard a couple really silly and (within my limits of comprehension) hilarious texts for Purim kiddush, the prayer of sanctifying a special day. The one (so far) posted here looks like it's pretty funny, but I can only comprehend part of it. (If anybody reading this is inclined to provide a translation, please consider adding it there. If you're not comfortable with that, though, please feel free to post here...)

Why didn't Esther follow Mordechai's instructions? This answer is fun, and check out the link in the answerer's first comment.

Is the torah in the public domain? Wikipedia says that only works published before 1923 are automatically public domain. The torah was written in 2448, so that's safe...

link roundup

Two items seen in rapid succession today:
  • Here's why you're not hiring the best and brightest: (Jeff Atwood) talks about making telecommuting work so that you really can hire the best employees, as opposed to the best employees willing to live in a particular location. I once applied for a telecommuting position at a company that seems to get it as far as that's concerned, and a lot of the stuff they do is reflected in this article.
  • What do programmers care about? (20-minute video): Joel Spolsky (Stack Exchange, Fog Creek) talks to recruiters about how to recruit programmers. If you've read Joel On Software you already know a lot of what he has to say here, but I still found it interesting to watch.

Can you help? Somebody asked a question recently on Writers about guidelines and heuristics for when to use screen shots in technical documentation. The question isn't looking for opinions or what you, personally, do but, rather, formal guidelines along the lines of what GNOME does for its documentation. So far it's only attracting opinion answers. I, too, have opinions and practices that I follow, but I can't source them either and I'd like to see the question get a good answer.

Speaking of Writers, I wrote a little something about writing good API reference documentation (like Javadoc), based on advice I've given informally over and over again -- finally wrote some of it down in a public place. Feedback welcome.

I recently saw an article with interesting-seeming observations and analysis of Modern Orthodox Judaism. I'm not all that tuned into the MO community and can't evaluate its credibility from inside, but I found it an interesting read. If any of y'all would care to tell me where on the spectrum from "yup" to "WTF?!" this is from your perspective, I'd be interested.

Finally, a little something for those who use the text editor vim (which I gather is related to vi?):

Doc Brown to the white courtesy phone, please

As part of a system upgrade at my shell provider, I'm now using Alpine to read mail instead of Pine. Pine showed me plain old dates/times in the list of messages, but Alpine tries to be clever and I haven't yet figured out how to turn it off. So instead of a date it'll say "Yesterday", or "Monday", etc. Very annoying, but it did produce a laugh:

I was unprepared for Alpine's treatment of the message I just got from somebody more than halfway around the world: "Tomorrow". Yes, tomorrow's mail today! Sadly, tomorrow's mail, so far, has not reported usable lottery numbers.

random bits

In the last two weeks we lost both [livejournal.com profile] merle_ and [livejournal.com profile] pedropadrao. I will miss them both. :-(

And there's no good transition from that to, well, miscellany, so this paragraph will have to serve.

I suppose, technically, if you're not sure if a TV show has jumped the shark, then it hasn't. But, that said, I doubt I'll be back for the next season of "Once Upon a Time", a show that got off to a good start in season one, carried it through part of season two, and then started going farther and farther afield of its original context. In addition to links to "the enchanted forest", the land of fairy tales, they mixed in an Arthurian knight (short-lived), Captain Hook, I think a couple other odd ones, and now, in the season finale, it's clear that Never-Never Land is going to be a major factor. If they were doing the work to tell a Gaiman-style story about all these realms being intertwined or some such I'd be on board for that, but it sure feels like they're just making things up as they go along now. Oh well.

[personal profile] thnidu over on Dreamwidth posted a link to "Earth as Art", which looks to be a nifty photo collection. The link isn't currently working for me, so I'm linking his entry instead of there for now.

More beautiful photography, from a locked post. Warning: gravity alert -- it wouldn't be hard to get sucked in.

Some time back I noticed that one of the regulars in the Mi Yodeya weekly parsha chat drew a lot on Abarbanel and that it sounded interesting. I asked him if he knew of an English translation and at the time he didn't, but more recently someone else who remembered my question pointed me at this adaptation (not translation). This sounds like something I should check out. (And it's kind of cool that, months later, somebody remembered my asking and followed up.)

misc updates

We did Thanksgiving dinner with my parents, sister, and niece, as usual. (My nephew is currently away at law school.) Someday my parents will decide that this is too much fuss and that's what they have children for, but apparently not yet. My niece brought her boyfriend, who I enjoyed talking with. I overheard my mother say to my father "that's the most I've heard Monica talk in ages" and, well, it's because there was more to talk about. Old family tropes only get you so far, and my mother and sister, at least, share basically no interests with me and Dani.

I've decided that Felix and Oscar aren't the right names for the cats; the initial behaviors that prompted them haven't continued. I'm currently leaning toward Orlando and Giovanni, which pass the random-friends-and-relatives test and the neighborhood test (would I be embarrassed calling an escapee?). A pair of perfectly-nice Italian names will suit, and if you happen to know that I'm a fan of Renaissance music, you might correctly detect a further inspiration for those names in particular. :-) (Orlando is the brown one, who's also the lovey guy who sleeps in my lap purring loudly.)

We had a couple of people over for board-gaming this weekend. History of the World plays differently with four players than with six. We also played San Juan (a "light" version of Puerto Rico), Automobile (only our second time playing), and Pandemic. I suspect we haven't really "gotten" Automobile yet; our scores were pretty close and nobody did anything really unusual. (Well, only one player took out loans, but other than that we seemed to be playing similar strategies.)

Some links:

HTTP Status Cats: the HTTP return codes illustrated. I've seen 408 (timed out) around, but many of these were new to me. Also, I didn't know about some of those status codes (402 I'm looking at you).
