comment Tish'im - mi yodeya?
While on the topic: Ksav Ari has the heads of the Tzadi facing away from each other; Ksav Beis Yosef has them facing each other. Heard from R' Hershel Shachter, machlokes mekubalim if the separate faces before Adam/Chava split were facing or separate, philosophical disagreement if it's "each for himself" (even before the first sin) or harmonious.

If you haven't guessed by now -- I started thinking about this because many places sell plucots, dinosaur eggs, etc. as new fruit for Rosh Hashanah!

So what about, say, someone else did plum X apricot; can that product now be hybridized with a plum? With an apricot? I recall seeing halachos about animal breedings, e.g. can a wolf-dog hybrid be bred with wolf or dog, but what about plants?

Rambam kilayim 3:6 says almond x peach is prohibited. (See actahort.org/members/showpdf?booknrarnr=470_26) Acc. to wikipedia, scientifically, almond and peach are cousins; plum and apricot are cousins; the two pairs are more distant from one another, so I'd assume no peach x plum. Probably not plum x apricot either. (See hort.purdue.edu/ext/senior/fruits/plum3.htm and hort.purdue.edu/ext/senior/fruits/apricot3.htm).

Woops my mistake about nectarines! If a nectarine is really just a kind of peach that would be okay.

@mekubal, yes the questions of what you can eat before hamotzee and still have covered by Birkat HaMazon are rather complicated.

comment Do you have to close your blog / website on shabbos?
E-commerce is a question. But you're not shipping the product till after shabbos. [Hm, what if it's fully electronic and instant, like selling e-cards or online-redeemable gift certificates?] As I said, Rabbi Heinemann first was machmir then reconsidered and was matir. Pay-per-click is an interesting one.

comment Which rabbi was it who checked a person's identity by asking where he sat in shul?
Thanks Alex. Hence my question.

comment What is a good way to make one's website inaccessible on Shabbat?
In theory, a "continue at your own risk" button could mean some people now will do one extra click to view your website. But I don't think that's a problem. (There are rabbis who have given a lost driver exact directions on Shabbos, "so he doesn't drive around any extra.")

comment Using Eiruv Tavshilin to Cook for a Gentile Shabbos Guest
Are you actually cooking something just for the one non-Jewish guest? Or merely making a slightly bigger soup for 1 more person?

Though it's about the rabbi's wisdom and insight rather than his piety per se.

comment Signifigance of the foods eaten on Rosh Hashanah?
Doesn't the Gemara ask that question (what kind of honey is the land flowing with?) with regards to the question if bee honey is kosher?

comment Signifigance of the foods eaten on Rosh Hashanah?
@mekubal, my impression was otherwise. (Acc. to wikipedia, beet sugar didn't happen until the 1500s.) I'm not sure what they were doing with dates in the time of the Talmud (paste? Juice?). But there's a reason that the word "sugar" in Hebrew is its Latin cognate -- ancient Hebrew had no word for it, only "dvash" for anything sweet.

@mekubal, you mean people aren't saying a bracha rishona on them? That's really weird. Or they say bracha rishona on them before hamotzi, then assume they'll be covered by birkat hamazon.

My impression, based on this, is that the definition of "fruit" vs "vegetable" here is a culinary one, not halachic. So strawberries for dessert get ha'adama; avocado in your salad doesn't get ha'etz.

Um, they were foods available 1500 years ago in Iraq that had Hebrew or Aramaic puns? (At the pshat level. It's certainly possible there's something deeper going on.)
