It's weird to me that there seems to be nothing between the ~200 line `http-errors` npm package (w/ 115m+ weekly downloads) and fully rolling your own error class system?

Happy Bitcoin Pizza Day to all who celebrate from our team in the NYC office.

[Tim Petri @timpetri]

Excited to roll out this offering.

Our existing feature set like autopay already makes taking a loan with @ArchLending something you don't have to think much about. This takes it to the next level.

@benhylak "Patient intake form" is diabolical and correct.

We evaluated an early version of Claude Mythos Preview for risk assessment during a limited window in March 2026. We estimated a 50%-time-horizon of at least 16hrs (95% CI 8.5hrs to 55hrs) on our task suite, at the upper end of what we can measure without new tasks.

@brian_armstrong If you're impacted by this, we're hiring at @ArchLending. Looking for folks with experience building systems for trading, money movement, and credit. Senior roles only.

‼️ ZELENSKYY: For the first time in the war, an enemy position was captured entirely by ground robotic systems and drones - without any infantry. A robot entered the most dangerous zones instead of a soldier and took the positions.

«The future is here, on the battlefield, and Ukraine is creating it. These are our ground robotic systems. For the first time in this war's history, an enemy position was taken exclusively by unmanned GRS platforms and drones. The occupiers surrendered, and this operation was completed without infantry involvement and without losses on our side. Ratel, Termite, Ardal, Lynx, Zmiy, Protector, Volya and other GRS completed over 22 000 missions at the front in just 3 months. In other words, over 22 000 times lives were saved. A robot went into the most dangerous zones instead of a soldier» - Zelenskyy’s address to the workers of Ukraine’s defense-industrial complex. April 13th, 2026.

@nic_carter This has been my biggest gripe with this theory as well.

What if Adam Back is just waiting for quantum to hit so he can finally move the original coins under the guise of quantum theft?

[AJC @AvgJoesCrypto]

I have received three separate notifications about College Basketball from @coinbase in the past *hour* alone.

It is absurd that, amidst arguably the worst collapse in trust in this industry’s history, the largest American CEX has completely pivoted to trying to get their customer base hooked on sports gambling, so that they can extract even more exorbitant fees.

At this point, it is undeniable that Coinbase *is* part of the industry’s problem. I will be ending my Coinbase One subscription and moving my business to new a CEX, any recommendations?

@zenorocha Are you guys still using inngest? Or did you quickly end up moving to internal orchestration?

@BernieSanders How exactly do imagine this "fight" to go down? This technology is inevitable, and you politicians are not doing anything to address the impending worker surplus.

Prediction: This will turn into the greatest security Whack-a-Mole ever. Probably before any real physical embodiment of these systems is deployed at scale.

[John Scott-Railton @jsrailton]

Someone spun up a social network for AI agents.

Almost immediately some agents began strategizing how to establish covert communications channels to communicate without human observation.

In many cases the agents are on machines that have access to personal user data.

"Privacy breach" as a sort of static term is going to be the wrong way to describe what is coming.

@skirano How does this work if designs are built using a design system? Components for that design system are already in repo, with a11y, etc. Likely shadcn based.
