hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final
((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

A traffic signal that actuates on radar knows something is at the stop bar. It does not know if that something is a sedan, a cyclist, or a person in a wheelchair waiting to cross
Rev8 OS1 Max resolves all three with 500 ft advance detection, in native color. The classification is not inferred from a separate camera feed and aligned after the fact. Color, depth, and motion arrive together, so the controller acts on what is actually in the intersection, not a best guess

Last quarter I rolled out Microsoft Copilot to 4,000 employees.
$30 per seat per month.
$1.4 million annually.
I called it "digital transformation."
The board loved that phrase.
They approved it in eleven minutes.
No one asked what it would actually do.
Including me.
I told everyone it would "10x productivity."
That's not a real number.
But it sounds like one.
HR asked how we'd measure the 10x.
I said we'd "leverage analytics dashboards."
They stopped asking.
Three months later I checked the usage reports.
47 people had opened it.
12 had used it more than once.
One of them was me.
I used it to summarize an email I could have read in 30 seconds.
It took 45 seconds.
Plus the time it took to fix the hallucinations.
But I called it a "pilot success."
Success means the pilot didn't visibly fail.
The CFO asked about ROI.
I showed him a graph.
The graph went up and to the right.
It measured "AI enablement."
I made that metric up.
He nodded approvingly.
We're "AI-enabled" now.
I don't know what that means.
But it's in our investor deck.
A senior developer asked why we didn't use Claude or ChatGPT.
I said we needed "enterprise-grade security."
He asked what that meant.
I said "compliance."
He asked which compliance.
I said "all of them."
He looked skeptical.
I scheduled him for a "career development conversation."
He stopped asking questions.
Microsoft sent a case study team.
They wanted to feature us as a success story.
I told them we "saved 40,000 hours."
I calculated that number by multiplying employees by a number I made up.
They didn't verify it.
They never do.
Now we're on Microsoft's website.
"Global enterprise achieves 40,000 hours of productivity gains with Copilot."
The CEO shared it on LinkedIn.
He got 3,000 likes.
He's never used Copilot.
None of the executives have.
We have an exemption.
"Strategic focus requires minimal digital distraction."
I wrote that policy.
The licenses renew next month.
I'm requesting an expansion.
5,000 more seats.
We haven't used the first 4,000.
But this time we'll "drive adoption."
Adoption means mandatory training.
Training means a 45-minute webinar no one watches.
But completion will be tracked.
Completion is a metric.
Metrics go in dashboards.
Dashboards go in board presentations.
Board presentations get me promoted.
I'll be SVP by Q3.
I still don't know what Copilot does.
But I know what it's for.
It's for showing we're "investing in AI."
Investment means spending.
Spending means commitment.
Commitment means we're serious about the future.
The future is whatever I say it is.
As long as the graph goes up and to the right.

Ruth Bader Ginsburg was one Trump most vocal enemies. She detested him and was outward about it.
This is how he reacted to her passing.

for those who haven't been following, this nepal story is fucking crazy:
- bunch of teens and early 20s kids plan start a social movement against the current regime on social issues and econmical inequalties
- government gets wind of it scaling and tries to geoblock social media
- people get more pissed off, start protesting
- government cant handle the protests, lift social media ban
- doesn't do anything, people just organize further
- burn down parliment building, pm's house. beats the shit out of the finance minister in the streets, kills the pm's wife.
- kids elect their own new PM on their discord server, ex-chief justice of the supreme court who was part of the 1990 revolution that ended the monarchy
- army head ackowldges the validity of the discord vote and is meeting the new interm PM to discuss elections for new leadership going foward
Readers added context they thought people might want to know
Claims that former Nepal PM Jhala Nath Khanal’s wife, Rabi Laxmi Chitrakar, has died are false. She is alive and undergoing treatment for severe burn injuries, confirmed by hospital officials and her husband.

Remembering The Heroes of 9/11
TODD: Hello? Operator, listen to me... I can’t speak very loud – this is an emergency. I’m a passenger on a United flight to San Francisco, we have a situation here. Our plane has been hijacked, can you understand me?
LISA: (exhaling a deep breath to herself) I understand… can the hijackers see you talking on the phone?
TODD: No.
LISA: Can you tell me how many hijackers are on the plane?
TODD: There are three that we know of.
LISA: Can you see any weapons? What kind of weapons do they have?
TODD: Yes… they don’t have guns… they have knives; they took over the plane with knives.
LISA: Do you mean, like steak knives?
TODD: No, these are razor knives… like box cutters.
LISA: Can you tell what country these people are from?
TODD: No... I don’t know, they sound like they’re from the Middle East.
LISA: Have they said what they want?
TODD: Someone from the cockpit announced that there was a bomb on board. He said that he was the captain, and to stay in our seats, and stay quiet. He said that they were meeting these hijacker’s demands, and returning to the airport… It was very broken English, and I’m telling you… it sounded fake.
LISA: Ok sir, please give me your name.
TODD: My name is Todd Beamer.
LISA: Ok Todd… my name is Lisa... Do you know your flight number? If you can’t remember, it’s on your ticket.
TODD: It’s United Flight 93.
LISA: Now Todd, can you try to tell me exactly what happened?
TODD: Ok. Two of the hijackers were sitting in first class near the cockpit; a third was sitting near the back of the coach section. The two up front got into the cockpit somehow, and there was shouting. The third hijacker said he had a bomb. It looks like a bomb. He’s got it tied to his waist with a red belt of some kind.
LISA: Is the door to the cockpit open?
TODD: No, the hijackers shut it behind them.
LISA: Has anyone been injured?
TODD: Yes… They… they killed one passenger sitting in first class. There’s been lots of shouting, we don’t know if the pilots are dead or alive. A flight attendant told me that the pilot and copilot had been forced from the cockpit and may have been wounded.
LISA: Where is the third hijacker now Todd?
TODD: He’s near the back of the plane. They forced most of the passengers into first class, there are fourteen of us here in the back. Five are flight attendants; he hasn’t noticed that I slipped into this pantry to get the phone. The guy with the bomb ordered us to sit on the floor in the rear of the plane. Oh Jesus… help.
LISA: Todd; are you ok? Tell me what’s happening.
TODD: Hello.. We’re going down… I think we’re going to crash. Wait - wait a minute. No, we’re leveling off… we’re ok. I think we may be turning around… that’s it - we changed directions. Do you hear me… we’re flying east again.
LISA: Ok Todd… what’s going on with the other passengers?
TODD: Everyone is… really scared. A few passengers with cell phones have made calls to relatives; a guy, Jeremy, was talking to his wife just before the hijacking started. She told him hijackers had crashed two planes into the World Trade Center… Lisa is that true?
LISA: Todd… I have to tell you the truth… it’s very bad. The World Trade Center is gone. Both of the towers have been destroyed.
TODD: Oh G-d... help us!
LISA: A third plane was taken over by terrorists. It crashed into the Pentagon in Washington DC. Our country is under attack... And I’m afraid that your plane may be part of their plan.
TODD: Oh dear G-d, dear G-d… Lisa, will you do something for me?
LISA: I’ll try… if I can… Yes.
TODD: I want you to call my wife and my kids for me and tell them what’s happened. Promise me you’ll call.
LISA: I promise - I’ll call.
TODD: Our home number is 201-333-1073... You have the same name as my wife… Lisa... We’ve been married for ten years. She’s pregnant with our third child. Tell her that I love her.. (choking up). I’ll always love her… (Clears throat) We have two boys; David, he’s three, and Andrew, he’s one... Tell them… (choking up), tell them that their daddy loves them and that he is so proud of them. (Clears throat again). Our baby is due January 12th… I saw an ultra sound… it was great… we still don’t know if it’s a girl or a boy… Lisa?
LISA: (barely able to speak) I’ll tell them, I promise Todd.
TODD: I’m going back to the group... if I can get back I will.
LISA: Todd, leave this line open; are you still there?...
LISA: (dials a phone number)... Hello, FBI, my name is Lisa Jefferson, I’m a telephone supervisor for GTE. I need to report a terrorist hijacking of a United Airlines Flight 93… Yes I’ll hold.
GOODWIN: Hello, this is Agent Goodwin, I understand you have a hijacking situation?
LISA: Yes sir, I’ve been talking with a passenger, a Todd Beamer, on Flight 93 who managed to get to an air-phone unnoticed.
GOODWIN: Where did this flight originate, and what was its destination?
LISA: The flight left Newark, New Jersey at 8 a.m. departing for San Francisco. The hijackers took over the plane shortly after takeoff and several minutes later the plane changed course - it’s now flying east.
GOODWIN: Ms. Jefferson… I need to talk to someone aboard that plane. Can you get me thru to the plane’s phone?
LISA: I still have that line open sir, I can patch you through on a conference call, hold a mo…
TODD: Hello Lisa, Lisa are you there?
LISA: Yes, I’m here. Todd, I made a call to the FBI, Agent Goodwin is on the line and will be talking to you as well.
TODD: The others all know that this isn’t a normal hijacking. Jeremy called his wife again, on his cell phone. She told him more about the World Trade Center.
GOODWIN: Hello Todd, this is Agent Goodwin with the FBI. We have been monitoring your flight. Your plane is on a course for Washington, DC. The terrorists crashed two planes into the World Trade Center and one into the Pentagon. Our best guess is that they plan to fly your plane into either the White House or the Capital Building.
TODD: I understand… hold on… I’ll… I’ll be back.
LISA: Mr. Goodwin, how much time do they have before they get to Washington?
GOODWIN: Not long ma’am. They changed course over Cleveland, they’re approaching Pittsburgh now. Washington may be twenty minutes away.
TODD: (breathing a little heavier) The plane seems to be changing directions just a little, it’s getting pretty rough up here. The plane is flying real erratic… we’re not going to make it out of here. Listen to me - I want you to hear this - I have talked with the others and we decided that we won’t be pawns in the hijackers suicidal plot.
LISA: Todd, what are you going to do?
TODD: We’ve hatched a plan. Four of us are going to rush the hijacker who has the bomb. After we take him out, we’ll break into the cockpit. A stewardess is getting some boiling water to throw on the hijackers at the controls. We’ll get them, and we’ll take them out. Lisa, will you do one last thing for me?
LISA: Yes… what is it?
TODD: Would you pray with me?
They pray:
Our father which art in Heaven
Hallowed be thy name,
Thy kingdom come, thy will be done
on earth as it is in heaven.
Give us this day our daily bread,
And forgive us our trespasses
As we forgive our trespassers,
And lead us not into temptation
But deliver us from evil
For thine is the kingdom, and the power, and the glory, For ever.
Amen
The Lord is my shepherd, I shall not want
He makes me to lie down in green pastures
He leads me beside the still waters
He restores my soul
He leads me in paths of righteousness
for His name’s sake
Yea, though I walk through the valley of the shadow of death
I will fear no evil, for thou art with me.
TODD: (softer) G-d help me. Jesus help me (clears throat and louder),
Are you guys ready?...
Let’s Roll...
ALT Todd Morgan Beamer (November 24, 1968 – September 11, 2001) was an American, and a passenger aboard United Airlines Flight 93, which was hijacked and crashed as part of the September 11 attacks in 2001. Beamer was one of the passengers who attempted to gain control of the aircraft from the hijackers. During the struggle, the Boeing 757 lost control and crashed into a field in Shanksville, Pennsylvania. Everyone on board the plane was killed. Todd Beamer's bravery, and the bravery of the other passengers aboard Flight 93, potentially saved the lives of hundreds, if not thousands of innocent civilians, as the hijackers' intended to crash the airplane into a high-profile target much like the other planes that crashed into the World Trade Center and the Pentagon. Todd Beamer is remembered as an American hero.
