Tanker traffic through the Strait of Hormuz has all but stopped since yesterday.

screenshot of a Polymarket account (TJlaoyang) that shows they joined in Feb 2026, made one trade, buying 167,844.9 shares that the US would strike Iran on Feb 10, 2026 and lost about $2000

here's a random account whose only bet is (incorrectly) buying 167k shares that the US would strike Iran two weeks ago at 1.2Β’

that's the exact kind of thing that would look like an obvious signal in retrospect if they were right, but they weren't. how could you know the difference beforehand?

I don't think that's right. people start new accounts and place big bets all of the time. the things that makes the trades suspicious (the timing, the accuracy) are things that are only apparent in retrospect

FT Alphaville | Substack We're the FT's finance blog. If it's dumb, delightful or just weird and involves money we're probably interested in it. Click to read FT Alphaville, a Substack publication.

ICYMI, FT Alphaville now has a Substack, which doesn’t cost a thing.

Yes, there are a LOT of newsletters these days. But if you appreciate stupidly detailed explorations of finance and economics, judicious shitposting and killer charts, then please sign up? ftav.substack.com

at some point in the next few years, I hope people eventually understand that the clunky code these LLMs write is:
- great for replacing common/low-complexity/low-risk programming tasks (a lot of those!)
- not so good for unusual/difficult/high-risk stuff (replacing legacy COBOL)

I've got the A1 too! but without the combo, so can't really do multi-color printing (which I think I need for lithophanes)

was looking at getting the AMS for it, but recently I've been considering just reselling my A1 and getting a P1S

printed these little corner spacers to keep the aluminum sheet in place on the back of the. they have "wings" on two sides that slide into the groove of the frame and a glued-in bolt that threads through the aluminum sheet. worked out in a pretty nifty way that didn't require gluing the spacers

there are some differences for sure. but at a basic level, there seem to be some misunderstandings over what the difficult parts of software development are and what we should be impressed by that are leading people to some wrong conclusions about what these AI tools can/are replacing

Paragraph from a story in The Atlantic: "But the labor market for office workers is beginning to shift. Americans with a bachelor’s degree account for a quarter of the unemployed, a record. High-school graduates are finding jobs quicker than college graduates, an unprecedented trend. Occupations susceptible to AI automation have seen sharp spikes in joblessness. Businesses really are shrinking payroll and cutting costs as they deploy AI. In recent weeks, Baker McKenzie, a white-shoe law firm, axed 700 employees, Salesforce sacked hundreds of workers, and the auditing firm KPMG negotiated lower fees with its own auditor. Two CNBC reporters with no engineering experience β€œvibe-coded” a clone of Monday.com’s workflow-management platform in less than an hour. When they released their story, Monday.com’s stock tanked."

The sentence, "Two CNBC reporters with no engineering experience β€œvibe-coded” a clone of Monday.com’s workflow-management platform in less than an hour." is highlighted

also to be clear, I am kind of subtweeting this anecdote

I don't care at all about monday.com, but it seems very silly that their stock would tank over this "vibe coding", but not tank when I clone any of the 1000+ public repos here: github.com/topics/kanba...

what's the difference, practically?

tbh, it's less a "credit" thing and more the inability to discern what is impressive/novel while writing about how impressive the tools are

it's like being impressed that the "auto-painting machine" can make you Bob Ross paintings. you could've painted those yourself already!

part of why this is bugging me so much is that it seems many people are discovering the value of open source software, but crediting it to tools that are trained on it

these tools can do many amazing things, but I promise you that "barebones monday.com board that runs locally" was already possible

19.02.2026 03:31 πŸ‘ 21 πŸ” 5 πŸ’¬ 4 πŸ“Œ 0

basic versions of these kinds of apps are easy to build (and the parts you can build in 15 minutes and run locally are not the tricky parts). that's why there are so many open-source versions on the internet, which is also a big part of why the LLMs are so good at making them

19.02.2026 03:20 πŸ‘ 10 πŸ” 1 πŸ’¬ 1 πŸ“Œ 0

it only took you 15 minutes to vibe code a version of the monday.com kanban board? ok, I bet I can walk you through finding and forking a repo in less time than that and you still won't need to write any code. at some level, that's really not very different than what Claude is doing

19.02.2026 03:14 πŸ‘ 8 πŸ” 1 πŸ’¬ 1 πŸ“Œ 0

something that I wish people would understand is that the kinds of apps that are easiest to "vibe code" a working version ofβ€”kanbans, news aggregators, blogsβ€”are also the kinds of tools that there are countless open source, free, forkable versions of on GitHub/elsewhere, and that's not a coincidence

ICE agents hate being filmed Trump administration accused of trampling First Amendment by targeting Americans recording immigration raids

Critics fear these tactics have a β€œchilling effect”, discouraging people from filming. The result? β€œThese agents get to effectively be as unaccountable as any group in the history of our country,” says David Bier, of the Cato Institute.

ICE agents are also invoking a federal criminal statute, 18 U.S.C. Β§ 111, which makes it a crime to interfere with federal officers while performing their duties. Civil rights experts say the statute is being misapplied, as recording agents does not constrain their ability to carry out operations.
