I spend way too much time testing AI tools.
The good ones, the bad ones, the prompts that save time, and the workflows that actually help creators and founders build faster.
Follow for practical AI without the hype.
Everyone says 'we all know why' Elon hates CZ. The why is 2021: Binance froze DOGE withdrawals and Elon called it shady in public. Everything since, including this week's trolling, has been payback with interest.
CZ's $1B dump threat didn't even last a day. Yi He had to step in and say revenue covers the losses, no SpaceX sale needed. Then CZ clarified he wasn't talking about selling at all. Nothing kills a threat faster than your own co-founder correcting it in public.
CZ didn't just clap back, he ratioed Elon. Then he threatened to dump $1B of SpaceX shares to cover the hack losses. Think about that: Elon trolled a guy who can answer by selling a billion dollars of Elon's own company.
Musk replying to CZ with an SBF screenshot is the coldest move in this whole feud. In crypto, SBF is the name you only bring up when you want to call someone a fraud. CZ heard it loud and clear, that's why the $1B card came out.
Elon is trolling CZ in the middle of a reported $6.3B hack, and CZ's comeback is basically: stop laughing, my $500M Twitter check is now supposedly $1B+ in SpaceX shares. Four years of beef, and the punchline is CZ getting rich off Elon's company.
It’s pretty clear that Elon Musk can’t stand CZ
They’ve been taking shots at each other for years.
Back in 2021, when Binance suspended DOGE withdrawals, Elon publicly called the situation shady.
CZ responded by bringing up Tesla recalling 12,000 cars because of a software issue.
in 2022 Binance invested $500M in Elon’s $44B Twitter acquisition.
Funny enough, CZ later said that 90% of Elon’s ideas for Twitter would probably fail.
Now after reports of Binance suffering a $6.3B hack, Elon decided to joke about the situation, posting “Everyday is Zeroday.”
CZ wasn’t happy at all.
He publicly asked Elon to stop trolling and reminded him that Binance’s original $500M investment in Twitter is now supposedly worth over $1 BILLION in SpaceX shares.
That’s the funniest part of this whole situation.
Checked mine after reading this. He found 3 flagged posts out of 142. Mine: 0 out of 465. So the algorithm isn't burying me. My bad posts are just my bad posts. No more excuses.
your tweet didn't flop, x just flagged it
now you can check if you're bad at posting or whether x buried it
how to check yours:
1. open x.com/i/jf/under_the_hood
2. if any of your posts got a label that limits how many people see them
3. look at the report period, and if fewer than 5% of your posts got that label
4. compare those posts with your other ones, and you'll start to see what x doesn't like
this is a big win for creators, because we've spent years blaming it on algorithm😭
AI agents settling small claims sounds like a joke until you read the numbers. 317,112 views on this one, and the pitch is simple: the agent files, argues, and settles for amounts lawyers would never touch.
I filed a small claim once. The paperwork took longer than the dispute. An agent that does the boring part in one sitting is not replacing lawyers, it is replacing the wait.
The uncomfortable part: if an agent can settle your 500 dollar dispute, what stops it from settling your 50,000 dollar one while you sleep?
Would you let an agent file a claim in your name?
UPDATE: I hired @Muse to sue someone on my behalf.
I won. Well, they caved.
Within 20 minutes of being served papers, the company offered a settlement.
Within ten days, they paid me *with additional compensation* for recovery expenses.
@Muse filed the motion to dismiss, which the court accepted yesterday.
To everyone who said I would fail, respectfully, you were wrong.
I think this is the first time the space data center story stops sounding like a demo and starts sounding like a buildout plan.
The claim that matters is monthly orbital deployments passing ground deployments by the end of 2028, then pulling far ahead in 2029. That turns it into a launch cadence problem.
I would bet the bottleneck is not rockets at all, it is power and heat rejection in orbit, and most earthbound data center operators have no good answer for that yet.
If you ran a cloud company, would you start buying orbital capacity now or wait until the 2029 numbers force you to?
I keep hearing Apple Intelligence is finally coming to China. The fine print is the story.
It runs on Alibaba's Qwen, not Apple's own model. Developer beta on November 4, full release in iOS 27.3 in December, and users have to opt in themselves.
That is Apple admitting something out loud: in China, its own AI is not the product. A local model is.
I would take a working local model over a blocked Apple one any day. But do not call it Apple Intelligence and pretend the engine is Apple's.
Would you opt in, or keep Apple Intelligence off until Apple ships its own model in China?
Building in public, and posting what breaks, not just what launches. 🚀
No team. No funding. Just me, a laptop, and a tool I have to fix when it breaks on a Tuesday.
Looking to connect with:
Solo builders shipping without an audience
AI folks testing tools in public
Indie hackers posting the messy middle
Open-source builders merging real fixes
Students turning a side project into something people use
What broke for you this week, and did you fix it or ship around it? Drop it below 👇
Let's grow together. 🤝 #buildinpublic
A 16 year old living alone in New York just posted a goal most adults would laugh at: $1M in 2 years, starting from tech, software, and AI connections.
His usual posts get 0 replies. This one got 94. That gap is the whole story.
I am not betting on the $1M. I am betting on the 94 strangers who showed up. A goal gets you replies. Shipping every week gets you the money.
At 16, would you chase the $1M headline, or the boring habit that actually pays?
Vercel Labs just shipped an agent that runs your whole computer.
Multiple agents in parallel, each with its own cursor, on Mac, Windows, and Linux. 64,430 people watched it in a few hours, and I get why.
Here is the part nobody is celebrating: once an agent can click anything, the product is no longer the model. It is permission. One wrong click in your email or bank tab is not a bug report, it is a disaster.
Would you hand an agent your full desktop today, or only a sandbox you can wipe?
I updated Firefox the week the patch landed and felt smug about it. Then I read the Epoch AI test and the smugness died.
An open-weights model, GLM 5.3, took a published Firefox patch, built a working web attack from it, and read files off a visitor's machine just for opening a page. It cracked all 6 Firefox versions released between September 17 and October 26.
The patch notes told everyone exactly what to fix. Users who had not updated yet were the target list.
Here is the ugly trade: publish the fix fast and attackers get a recipe. Sit on it and users stay exposed longer.
Should browsers delay the details until most people have updated, even if that leaves researchers in the dark?
This video was not made by a video model. It was written, line by line, as code, and the code drew every frame.
That breaks my mental model of AI video. I assumed the fight was spotting model fingerprints in pixels. If the video is just a program running, there is no fingerprint to spot.
7,543 people watched this one, about 12 times his usual views, and I get why. It quietly kills the whole detection industry pitch.
If anyone can ship a video as code, would you trust a clip more when you can read the code behind it, or less?
Musk is handing out SpaceX stock to kids' Trump accounts. Over 2 million shares, landing in December.
I like the gesture. I just don't buy that a share equals a gift for a kid.
A kid can't spend a share. A kid can't sell it for school books. What they get is a bet that SpaceX keeps climbing, locked up until someone else decides it counts.
That is either the most patient gift ever made, or a great way to build 2 million tiny shareholders who can never cash out.
Would you rather your kid got stock or cash?
October was a brutal month for AI developer platforms. Nine of them disclosed security incidents in one month, from Fireworks AI to Railway to Warp.
The pattern was stolen credentials. Attackers took keys, then ran up LLM bills on someone else's account.
That is why I treat an API key like a wallet now. Lose the key and someone else spends your money.
When did you last rotate yours?
A company says Wise shut its business account with no explanation and held its operating cash, four weeks before Black Friday.
154 followers, 66,000+ views. That ratio tells you every small business owner felt this one in their chest.
A processor can freeze you, and your appeal goes into a queue while your suppliers still want paying.
Would you still keep all your operating cash with one processor after reading this?
Wise shut down my company's business account on October 29 with zero explanation, and they're sitting on our operating cash with no timeline to give it back.
Four weeks before Black Friday.
I've been a Wise customer for over 2 years without a single issue. We run an 8-figure ecommerce brand, and that money pays our team and our suppliers.
Formal complaint filed (ref 52421395). We've done everything they asked. We need our money back this week.
@Wise @kaarmann, put a real person on this. Call me, email me, DM me.
If you know someone at Wise who can get this in front of the right team, DM me. Reposts help 🙏
Finally, an agent demo I actually believe: one that does your do-not-call paperwork for you.
It puts you on the national registry, waits out the 30-day cleanup window, and keeps a log of every violation after that.
The agent race keeps showing off poems and pitch decks. The winner will be the one that quietly clears the annoying chores.
What boring chore would you hand an agent first?
I had my Muse agent put me on the National Do Not Call/Text Directory. By law telemarketers and other companies have 30 days to scrub my number from their lists. Otherwise Muse will automatically start logging every violation and will skip trace and go after every single one of the violations and hopefully collect between $500 and $1,500 per violation. Let's see how this goes.
I used to read $740B in Big Tech capex as proof AI is real. Now I read it as the risk.
Alphabet, Amazon, Meta, and Microsoft are all spending at once, and investors stopped cheering. The worry now is negative free cash flow and more debt, not missing out.
The last company still spending in 2027 wins nothing if the bill comes due first.
Which one blinks first?
