A Minnesota synagogue built an ice rink — and is inaugurating it with a klezmer skate
(JTA) — A forecasted low of -16 degrees in the Twin Cities on Thursday has the stage set perfectly for two frozen Jewish firsts — a Klezmer on Ice festival and a synagogue-run skating rink.
Such is life in Minnesota, where bone-chilling temperatures are no match for Jewish festivities.
“It kind of shows us the Minnesota-style of thinking about the winter where just because it’s freezing cold outside, you don’t have to stop doing everything,” said Marcus Rubenstein, rabbi at Temple of Aaron in St. Paul.
“I used to be a rabbi in New York. They said you couldn’t schedule any big events in the winter because no one would come in case it snowed,” Rubenstein said. “But [here] sometimes it will snow 6, 7 inches and be -5, -10 degrees, and you’ll have everybody come out. I mean people in their 80s, 90s to little kids. And they just put on their coats and go out and have fun.”

Temple of Aaron, a Conservative congregation of about 700 families, is inviting families to bundle up and have fun on what Rubenstein believes is the first-ever skating rink on a synagogue property. The rink, which can accommodate about 30 people at a time, was built and is being maintained by “Ice Captains” — synagogue members who clear it of snow and shovel off any extra ice that forms.
On Thursday, skaters at the rink heard the kickoff performance of the klezmer festival, featuring Jewbalaya, a hybrid klezmer and New Orleans jazz band in which Rubenstein plays the trumpet.
But the music will be piped in from inside the synagogue — a concession, Rubenstein and others associated with the festival said, to the cold.
Last week, musicians promoting Klezmer on Ice with a pre-festival performance alongside Lake Harriett, the (usually frozen-over) body of water at the heart of Minneapolis, ran into some technical challenges. Anticipating frigid temperatures, the musicians planned to play from a lakeside booth decorated like a boom box as part of a pop-art initiative called Art Shanty. But there was a wrinkle.
“We were supposed to have a sousaphone player who by the time they got their heavy big brass instrument into the box, the valves were frozen so they couldn’t play,” said Josh Rosard, an organizer of Klezmer on Ice. The performance went on without the sousaphone.
It’s not just brass instruments that are vulnerable to cold snaps. Strings and woodwinds can quickly go out of tune in the cold, as metal contracts and wood begins to warp. Clarinets and violins, staples of the Eastern European Jewish music genre, just can’t take it.
That’s why most of the Klezmer on Ice events will take place indoors — including but not only at Temple of Aaron. On the schedule for the weekend-long festival are local and national performers Sarina Partridge, Tzipporah Johnson, Izzy Buckner, the Klezmommies and the band Midwood. There will also be a cabaret variety show; klezmer-infused Shabbat services; and a luminary Havdalah ceremony.
Rosard said he saw the event as a breakout moment for the Twin Cities’ klezmer scene and, given the strong track record of longstanding klezmer festivals at spawning new acts, an opportunity.
“I’m really excited for what players in the community are going to take out of the workshops in particular and excited to see what may come out of it in the future,” said Rosard, who grew up casually playing the accordion but got more seriously involved in the klezmer world during the pandemic. He met his Klezmer on Ice co-organizer, Jewish musician and folklorist Sarah Larsson, with whom he attended KlezCanada and the Portland Klezmer Festival.
Still, he acknowledged, “It’s a little bit tongue in cheek to do something like this in the middle of February in Minnesota.”
Rubenstein said his congregants are up for it. Temple of Aaron’s new ice rink will be open not only during the klezmer festival’s opening night but for skating sessions most Saturdays after Shabbat morning services and Hebrew school classes finish.

If the activity isn’t exactly standard after-synagogue fare, it’s perfectly permitted under the Conservative movement’s interpretation of Jewish law. The movement, of which Temple of Aaron is a part, permits non-competitive ice skating on Shabbat, so long as no Shabbat rules are violated (such as driving to or from a rink or paying to rent skates), and the skating takes place within the boundaries of an eruv, or Jewish legal enclosure inside which certain objects can be carried on Shabbat.
Rubenstein said he was thinking about the activity in different terms — as it relates to making Temple of Aaron a centerpiece of a St. Paul Shabbat.
“The kids are ice skating anyway,” he added. “So why not ice skate at shul and come do it together with their Jewish friends, and build community that way?”
Temperatures are supposed to rise over the course of the weekend, but the high on Friday should be in the low single-digits. So for the klezmer performance that is supposed to take place at Lake Harriet, Rosard says, a plan is in place to avoid last weekend’s snafus.
“We’ll have the sousaphone player drive up as close as possible, then run-slash-briskly walk straight into the performance shelter,” he said. “We didn’t quite have the urgency last time.”

Iron Beam: IDF’s First Operational High-Power Laser Defense System

i24 News – Israel has achieved a major technological breakthrough in defense with the delivery of its first operational high-power laser system, “Or Eitan” (Iron Beam), to the IDF. The handover took place Sunday at Rafael’s facility, with Defense Minister Israel Katz and senior military and industry officials in attendance.
Developed over several years, “Iron Beam” is the first interception laser of its kind in the world to reach operational maturity.
During extensive testing, the system successfully intercepted rockets, mortar shells, and drones under conditions simulating real combat scenarios.
The laser will be integrated into Israel’s multi-layered air defense network, complementing the Iron Dome, David’s Sling, and Arrow systems. Operated by the Israeli Air Force, it offers a significant economic advantage: its marginal cost per interception is nearly zero, a major shift in the cost equation for missile defense.
The project was led by the Ministry of Defense’s Directorate of Research and Development in close cooperation with Rafael, Elbit Systems, responsible for the laser source, and other Israeli defense companies. Combining an advanced laser source with a unique electro-optical sight, the system provides maximum accuracy and efficiency at extended ranges.
The system’s name, “Or Eitan,” (Iron Beam) honors Captain Eitan Oster, who fell in battle in southern Lebanon.
Minister Katz described the milestone as a “game changer” that sends a strong message to Israel’s adversaries, from Tehran to Sanaa and Beirut. Rafael hailed the delivery as the beginning of the defensive laser era, placing Israel at the forefront of interception technology worldwide and reinforcing its strategic technological edge for future security challenges.

i24 News – A group of 21 Arab, Islamic and African countries, organizations and entities issued on Saturday a joint statement condemning Israel’s recognition of Somaliland sovereignty.
The statement’s signatories said that they condemn and reject Israel’s recognition of Somaliland “in light of the serious repercussions to peace and security in the Horn of Africa and the Red Sea region, and its serious impacts on international peace and security, which also reflects Israel’s clear and complete disregard for international law.”
It was signed by: Saudi Arabia, Egypt, Turkey, Iran, Pakistan, Qatar, Jordan, Algeria, Iraq, Kuwait, Oman, Libya, Palestine, Somalia, Sudan, Yemen, Comoros, Djibouti, Gambia, Maldives, Nigeria and the Organization of Islamic Cooperation (OIC).
The joint statement voiced support “for the sovereignty of Somalia and reject any measures that would undermine its unity, territorial integrity, and sovereignty over all its lands.”
The signatories also “categorically reject linking Israel’s recognition of the territory of the land of Somalia with any plans to displace the Palestinian people outside their land.”

Nvidia, Joining Big Tech Deal Spree, to License Groq Technology, Hire Executives

Nvidia has agreed to license chip technology from startup Groq and hire away its CEO, a veteran of Alphabet’s Google, Groq said in a blog post on Wednesday.
The deal follows a familiar pattern in recent years where the world’s biggest technology firms pay large sums in deals with promising startups to take their technology and talent but stop short of formally acquiring the target.
Groq specializes in what is known as inference, where artificial intelligence models that have already been trained respond to requests from users. While Nvidia dominates the market for training AI models, it faces much more competition in inference, where traditional rivals such as Advanced Micro Devices have aimed to challenge it as well as startups such as Groq and Cerebras Systems.
Nvidia has agreed to a “non-exclusive” license to Groq’s technology, Groq said. It said its founder Jonathan Ross, who helped Google start its AI chip program, as well as Groq President Sunny Madra and other members of its engineering team, will join Nvidia.
A person close to Nvidia confirmed the licensing agreement.
Groq did not disclose financial details of the deal. CNBC reported that Nvidia had agreed to acquire Groq for $20 billion in cash, but neither Nvidia nor Groq commented on the report. Groq said in its blog post that it will continue to operate as an independent company with Simon Edwards as CEO and that its cloud business will continue operating.
In similar recent deals, Microsoft’s top AI executive came through a $650 million deal with a startup that was billed as a licensing fee, and Meta spent $15 billion to hire Scale AI’s CEO without acquiring the entire firm. Amazon hired away founders from Adept AI, and Nvidia did a similar deal this year. The deals have faced scrutiny by regulators, though none has yet been unwound.
“Antitrust would seem to be the primary risk here, though structuring the deal as a non-exclusive license may keep the fiction of competition alive (even as Groq’s leadership and, we would presume, technical talent move over to Nvidia),” Bernstein analyst Stacy Rasgon wrote in a note to clients on Wednesday after Groq’s announcement. And Nvidia CEO Jensen Huang’s “relationship with the Trump administration appears among the strongest of the key US tech companies.”
Groq more than doubled its valuation to $6.9 billion from $2.8 billion in August last year, following a $750 million funding round in September.
Groq is one of a number of upstarts that do not use external high-bandwidth memory chips, freeing them from the memory crunch affecting the global chip industry. The approach, which uses a form of on-chip memory called SRAM, helps speed up interactions with chatbots and other AI models but also limits the size of the model that can be served.
Groq’s primary rival in the approach is Cerebras Systems, which Reuters this month reported plans to go public as soon as next year. Groq and Cerebras have signed large deals in the Middle East.
Nvidia’s Huang spent much of his biggest keynote speech of 2025 arguing that Nvidia would be able to maintain its lead as AI markets shift from training to inference.
