The presidents of @Harvard, @MIT, and @Penn were all asked the following question under oath at today’s congressional hearing on antisemitism: Does calling for the genocide of Jews violate [your university’s] code of conduct or rules regarding bullying or harassment? The answers they gave reflect the profound moral bankruptcy of Presidents Gay, Magill and Kornbluth. Representative @EliseStefanik was so shocked with the answers that she asked each of them the same question over and over again, and they gave the same answers over and over again. In short, they said: It ‘depends on the context’ and ‘whether the speech turns into conduct,’ that is, actually killing Jews. This could be the most extraordinary testimony ever elicited in the Congress, certainly on the topic of genocide, which to remind us all is: “the deliberate killing of a large number of people from a particular nation or ethnic group with the aim of destroying that nation or group” The presidents’ answers reflect the profound educational, moral and ethical failures that pervade certain of our elite educational institutions due in large part to their failed leadership. Don’t take my word for it. You must watch the following three minutes. By the end, you will be where I am. They must all resign in disgrace. If a CEO of one of our companies gave a similar answer, he or she would be toast within the hour. Why has antisemitism exploded on campus and around the world? Because of leaders like Presidents Gay, Magill and Kornbluth who believe genocide depends on the context. To think that these are the leaders of Ivy League institutions that are charged with the responsibility to educate our best and brightest. On the bright side, our congressional leaders deserve accolades for showing tremendous leadership and moral clarity in their statements, by the questions they asked, and the respectfulness with which they conducted the hearing. It was a masterclass of how our government and democracy should operate. If you have time, please watch the entire hearing. Throughout the hearing, the three behaved like hostile witnesses, exhibiting a profound disdain for the Congress with their smiles and smirks, and their outright refusal to answer basic questions with a yes or no answer.

As fighting in Gaza resumes, reminder that fire could cease tomorrow if: 1) Hamas releases all hostages 2) Disarms and destroys the tunnels 3) Hands over planners and perpetrators of the Oct 7 Massacre to justice 4) Disavows “From the River to the Sea” ideology. Shabbat Shalom.

🧵 I just witnessed ~45 minutes of footage of the October 7th terrorist attack at the @AtlanticCouncil courtesy of @IsraelinUSA along with colleagues from think tanks across the ideological spectrum. What I saw was worse than I’ve ever seen. Pure evil. ***Trigger Warning***

Oh you like Hamas? Siding with Hamas isn’t easy when you know what they actually stand for. Well done: FactsForPeace on IG

The only ‘occupiers’ in the Gaza are Hamas. If you care about ‘occupied’ Palestinians, care about the death-cult Hamas. And hope they are defeated.

Anyone in any doubt about what those marching today are calling for should know this. There would be peace tomorrow if Hamas laid down its arms. If the Israelis laid down their arms there would be a second Holocaust. The people marching either don't know this, or want it.

I call upon all Harry Potter fans around the world to share this picture in memory of the lovely Noya, a 13-year-old girl on the autistic spectrum who adored Harry Potter and whose tracks disappeared during the murderous terror attack by Hamas. Unfortunately, no whisper helped, and her story did not have a happy ending. Last night, her body was found. Hamas killed her too. Share in memory of Noya! #HamasisISIS

Ruth Peretz (16), seen here with her devoted father Arik (58), lived with cerebral palsy. Noya Dan, 12, lived with autism, while her grandmother Carmela, 80, battled dementia. All four were found dead yesterday, murdered in cold-blood by genocidal Hamas terrorists. Their crime? being Israeli. These are the people @Penn students vilify as "legitimate military targets". Theirs is the blood that "exhilirates" morally corrupt @Cornell professors. Their violent, senseless death is what Israel-haters define as "a day of celebration". Killing disabled people on account of their ethnicity is the most virulent evil a human being can commit. It puts our entire species to shame. Nothing -- not the "occupation", not even the tragic deaths of war -- comes close. Yet these horrors are precisely what Palestinian "heroism" is made of. #HamasisIsis #TheWestIsNext

Dear @AOC and friends: You don't understand the first thing about international law, but that doesn't stop you from spreading your ignorance. Here is a quick primer on the Law of Armed Conflict to explain why you and @Ilhan are incredibly, dangerously, wrong as usual:

Merci @Charlie_Hebdo_ Israel stopped providing water for Gaza and the Hamas-ISIS terrorist says: "how barbaric can one be" למעלה כתוב שישראל הפסיקה את אספקת המים לעזה ומחבל חמאס מגיב: עד לאן תגיע הברבריות? #حماس_هي_داعش #حرروا_فلسطين_من_حماس #therealimage #hamasisISIS #FreePalestineFromHamas @thalicim

Beheaded babies. This wasn’t an accidental consequence of war. These pure babies were hunted and beheaded. There aren’t two sides here. There is no moral equivalence. If you haven’t spoken up yet, it’s not too late. Don’t be complicit. Don’t remain silent.

@benediktbuenz All of them use basic DL NIZKPok

@benediktbuenz Threshold ECDSA wallets?

Is it fair to claim that Bulletproofs is the most widely used zero-knowledge proof today? Monero has ~20k transactions per day vs. ZCash <1k shielded. Anything outside blockchain? Don't want to make a false claim.

First (?) Exit for Israeli crypto(currency)-startup Congrats Ben Riva, Dan Yadlin, Itay Malinger and entire @curvmpc team, well done!

@SmartCryptology @curvmpc @PayPal I thunk that this is the first MPC exit!

מוקדם יותר היום אצל @kereneubach דיברנו @moshebst ואני יחד עם היועץ הכספי לרמטכל לשעבר ראם עמינח על תקציב הביטחון, פנסיה תקציבית וכל זה. היו הרבה אמוציות בשיחה הזו. מוזמנות ומוזמנים להאזין omny.fm/shows/kan-news…

@cryptodavidw Another property of the weak eddsa is related key attacks - given a valid signature for public key ok, one can create a signature on the same message for public key pk+xG for any x.

@cryptodavidw I believe both schorr and the weaker eddsa you described have the same property - in both one can create a single valid signature and a public key for which it doesn't know the secret key.

my article on Ed25519 still has one unanswered question: why does the challenge includes the public key of the signer? have you figured out the answer? cryptologie.net/article/497/ed…

Being quick to criticize and slow to praise makes managers feel tough, but it doesn't motivate employees. hbr.org/2017/05/why-do…
