Darn - the only one I missed on the quiz and it was because I forgot that the answers were based on another timezone 🤦‍♂️ Check out the quiz at jsdate.wtf

Screenshot of an incorrect answer in the jsdate.wtf quiz, the question was: `new Date("maybe 1")` and the correct answer was `2001-04-30T23:00:00.000Z` but I responded with `2001-05-01T00:00:00.000Z`.

Added a new feature to my personal site - post link preview tooltips! Hovering over links to blog posts shows a little detailed tooltip of the title, description, and publish date!

Tooltip showing above a link titled "Async Class Creation in JavaScript" with the contents of:

Async Class Creation in JavaScript
Published: Jun 3, 2025, 4:04:58 PM EDT
Have you ever wanted to create a class in JavaScript or TypeScript but also have the initialization be async? Here's a quick tip on a pattern that I've used in the past!

This feels weirdly misogynistic to me... Even if you took the gender out of the "role" of the agent, it feels weird to me to personify the agents like this Source: www.semafor.com/article/06/0... from @semafor.com

Screenshot of an article with part of the content highlighted:

Outside of YC, Pukar Hamal, CEO of SecurityPal — which helps companies automate responses to security-related questions during the sales process — is vibe coding agents to fill some open positions rather than hiring personnel.

START highlight:
SecurityPal needed a product manager, and instead of creating a job posting, Hamal spent three hours vibe coding an agent named Penelope, depicted as a brunette mountaineer wearing aviator goggles and a fur-lined bomber jacket (a nod to the company’s office in Nepal). “Penelope is going to be a very integral part of how I as a CEO make decisions,” he told Semafor. “She’s also going to be part of my leadership meetings, where we can interrogate her on different ideas we have.”
END highlight

SecurityPal has incorporated two vibe-coded agents into the security analyst team, which manages security data sharing between customers. The company onboarded them like it would any employee, and they participate in all-hands meetings — camera on. “We’ve probably already hired our last security analyst,” he said.

Installed an app on my phone and it showed this count down advertisement as an activity on the dynamic island. Immediately uninstalled the app

this is on par with twitter open sourcing their algorithm

xAI post on twitter:

We want to update you on an incident that happened with our Grok response bot on X yesterday.
What happened:
On May 14 at approximately 3:15 AM PST, an unauthorized modification was made to the Grok response bot's prompt on X. This change, which directed Grok to provide a specific response on a political topic, violated xAl's internal policies and core values. We have conducted a thorough investigation and are implementing measures to enhance Grok's transparency and reliability.
What we're going to do next:
- Starting now, we are publishing our Grok system prompts openly on GitHub. The public will be able to review them and give feedback to every prompt change that we make to Grok. We hope this can help strengthen your trust in Grok as a truth-seeking Al.
- Our existing code review process for prompt changes was circumvented in this incident. We will put in place additional checks and measures to ensure that xAl employees can't modify the prompt without review.
- We're putting in place a 24/7 monitoring team to respond to incidents with Grok's answers that are not caught by automated systems, so we can respond faster if all other measures fail.

Kinda wild that `useId` was released 3+ years ago and yet is still not compatible in CSS use cases. Need to consistently manage the `::` characters via `.replace`

Only took me 453 weeks to become a professional apparently

Notifications in Todoist, notifying me when i reached specific levels in their Karma scale. Top notification was from 1 minute ago saying I reached the Professional level, second notification was from 47 weeks ago saying I reached the Intermediate level, and the last notification was from 453 weeks ago saying that I was a Todoist Novice

This feels a bit clickbait-y to me, not all TS features work in Node yet:

Screenshot from a section of the quote post’s linked article, stating:

“Are Enums and Namespaces Supported?

Enums and Namespaces are not supported by default.”

And notes that you may need an additional flag still to support those features: “—experimental-transform-types”
