I don't think I can eat that much Judaism every day

The left tried for decades to pass green energy subsidies, passed them, the subsidies worked, and now literally the entire planet's electricity grid is going to convert to solar+battery. It just doesn't feel like "tech" because it mostly produces kinda boring blue collar jobs instead of billionaires

Every photo from Minneapolis looks like this. Cops decked out with guns and full tac gear facing off against people in bathrobes, parkas, and sweatpants armed only with whistles and cell phones.

Yet every verified MAGA chode on X dutifully calls it a riot or violent insurrection.

Zionism was never a single concept. We should be grateful to JFNA’s survey for the reminder. - Jewish Telegraphic Agency A Jew can believe in a Jewish, democratic state and still doubt whether contemporary Zionism advances both of those commitments, writes a scholar of European Jewish intellectual history.

I wrote about what it tells us that Martin Buber, a proud Zionist during his life, would probably be considered an anti-Zionist by the standards of what the word means today. www.jta.org/2026/02/09/i...

STATEMENT FROM MATT MOBERG, CHAPLAIN OF THE
MINNESOTA TIMBERWOLVES

IF YOU'RE A CHURCH POSTING
PRAYERS FOR PEACE AND UNITY TODAY
WHILE MY CITY BLEEDS IN THE STREET.
MISS ME WITH THAT SOFTNESS
YOU ONLY WEAR
WHEN IT COSTS YOU NOTHING.

DON'T DRESS AVOIDANCE UP AS HOLINESS.

DON'T CALL SILENCE "PEACEMAKING."

DON'T LIGHT A CANDLE AND THINK IT SUBSTITUTES FOR SHOWING UP.

TONIGHT AN ICE AGENT TOOK A PHOTO OF ME NEXT TO MY CAR,
LOOKED ME IN THE EYE AND TOLD ME,
"WE'LL BE SEEING YOU SOON."

NOT METAPHOR.
NOT HYPERBOLE.
A THREAT DRESSED UP IN A BADGE AND A PAYCHECK.

PEACE ISN'T WHAT YOU ASK FOR WHEN THE BOOT IS ALREADY ON SOMEONE'S NECK.
PEACE IS WHAT THE POWERFUL ASK FOR WHEN THEY DON'T WANT TO BE INTERRUPTED.

UNITY ISN'T NEUTRAL.
UNITY THAT REFUSES TO NAME VIOLENCE
IS JUST LOYALTY TO THE ONES HOLDING THE WEAPONS.

STOP USING SCRIPTURE LIKE CHLOROFORM.
STOP CALLING YOUR FEAR "WISDOM."
STOP PRETENDING JESUS WAS CRUCIFIED BECAUSE HE PREACHED GOOD VIBES AND PERSONAL GROWTH.

YOU DON'T GET TO QUOTE SCRIPTURE
LIKE A LULLABY,
WHILE INJUSTICE STAYS WIDE AWAKE.

YOU DON'T GET TO ASK GOD TO
"HEAL THE LAND"
IF YOU WON'T EVEN LOOK AT THE WOUND.

THERE IS A KIND OF PEACE THAT ONLY EXISTS
BECAUSE IT REFUSES TO TELL THE TRUTH.

THAT PEACE IS A LIE. AND LIES DON'T GROW ANYTHING WORTH SAVING.

THE SCRIPTURES YOU LOVE WEREN'T WRITTEN TO KEEP THINGS CALM.
THEY WERE WRITTEN TO SET THINGS RIGHT.
AND SOMETIMES THE MOST FAITHFUL THING YOU CAN DO IS STOP PRAYING AROUND THE PAIN AND START STANDING INSIDE IT.

IF THAT MAKES YOU UNCOMFORTABLE-GOOD.

GROWTH ALWAYS IS.

Our researchers found at least 450 posts on Telegram dating back to 2020 that shared the song mentioned in this reporting.

Nearly all the posts we found were from explicitly neo-Nazi and white supremacist channels. And a review of our datasets found it hasn't circulated much outside those circles.

Great question!

It’s not just about whether or not the gyre is widening – its that the falcon cannot hear the Falconer. In today’s blood-dimmed world, it’s a game-changer that many don’t consider.

The kicker? A beast that is rough, slouching, and born.

The ICE shooting in Minneapolis shattered my Holocaust survivor father's' American dream The fatal shooting of RenΓ©e Good in Minneapolis by an ICE agent has made the daughter of a Holocaust survivor see the U.S. differently.

Beth is good and JCA is good and this piece is excruciating but good:

Governor Walz came to my kids school for Hanukkah today, but per my daughter the highlight of school was "I don't know, I can't remember".

Thanks for the ping and the kind words. The inconsistency here is due less to an intentional choice and more a compromise of efficiency vs correctness. I do think I can fix this with some work though - would you mind opening an issue to track?

I was playing proto-typing @jcristharif.bsky.social's msgspec to (de)serialize a big nested python object. Converting the object to a dict using `msgspec.to_builtins` was 50x faster than my current recursive method and json serialization was 7x faster than `json.dumps` for serializing the dict.

True. "Practicality beats purity" I guess 🀷 - relying on recursion in the parser eases the implementation, and seems to be fine for typical use. All software is tradeoffs, I'm happy enough with the ones I've made here.

25.11.2024 22:44 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

Sure. We do respect the python `sys.setrecursionlimit` setting though, so you can increase the recursion depth if needed (on modern systems the stack is pretty big).

In what application do you see json nested enough where this matters?

It will be three years next week that I have not owned a car. I could easily afford one. I have kids who do activities & stuff. I live in part of St Paul with ok transit & mediocre bike facilities. But, we have to make different choices if those kids will have a future. Here are some reflections. 🧡

A very serious line chart illustrating "Time from ideation to dissemination" crossing the x axis into negative territory.

A very serious line chart illustrating "Time from ideation to dissemination" crossing the x axis into negative territory.

Given the rate at which time from ideation to dissemination is decreasing, it's only a matter of time before we reach the posting-before-you-think-of-it tipping point.

This is a very serious chart.
