Reminds me of thus genius comic art by Quino
Scan of Quino comic art. The sequence shows a dinosaur attacking a human, then going extinct, getting buried, becoming into petrol over time, then humans evolving, extracting the petrol, creating plastic and fuel, using the fuel to power a car, then the car hitting a person. So the dinosaur wins in the end.

Goals can be modeled as a directed acyclic graphs, where each node is a task to make progress towards the end goal.

I'm working on an MCP server to capture and manage goals in this format with Claude.

Presentation coming soon!

Nice work Apple!

1. Font is horribly small and I don't know how to change it
2. I am signed in on a Mac device, I don't see any "Learn more" link
Here's the text from the screenshot from a Mac device popup: "We are evaluating your information to determine when you will be able to reset your password. We will contact you within 24 hours, at [redacted email address] to let you know when your waiting period will be over. Apple Support cannot help to reduce your waiting period. You can check the status of your request at iforgot.apple.com. If you are signed in on a Mac or iOS device, you can reset your password immediately. Select 'Learn more' for details."

Not to throw the baby out with the bath water, but Gemini will hallucinate quite badly when working with exported files. It will refer to files and code that doesn't exist, and I've seen many instances of this.

Beware of the hype!
Screenshot of Google Gemini AI output when uploading files. The referenced file "WorkspaceData.py" mentioned in the output does not actually exists. Transcription: "Okay, I've reviewed the Python code files you've provided. Here's a breakdown of the review, covering each module and overall observations: Code Review Overall, the project is well-structured with separate modules for data fetching, encoding, and main processing logic, along with corresponding tests. The use of pytest and libraries like responses and scikit-learn is commendable. Here are detailed points: 1. WorkspaceData.py Functionality: This module correctly fetches sequence and harmony data from the specified local URLs. Error Handling: It handles potential requests.exceptions.RequestException and checks for non-200 status codes."

Gemini was the perfect tutor until I said the word "time" 😂😂😂
Transcription of interaction with Gemini AI: Gemini: Exactly! So, just like a faster speed means more distance covered per unit of time, a higher tempo means more beats occurring per unit of time. Can you see a common thread here in how we're describing these changes? What are we always relating the change in something to? Me: Time Gemini: It's 10:11 AM.

State management is hard! Specially when it involves global context shared across different components.

If you learn how to nail this problem you'll stand out.
Screenshot of GitHub UI where a tab shows a counter with 3 open issues, when the counter in the list below shows there are zero open issues. This is a common challenge in websites where state context is shared globally across different components that need to be synchronized.

You know who wins the war? Whoever shares some insight upfront without teasing content just to lock it behind a subscription paywall, which btw I can only see after closing a popup and dismissing the notifications popup.

Testing the waters with #MCP I created a very simple server that allows Claude to fetch all my issues from a repo.

The fact that you can combine this with pre-existing project data already provided to Claude is very useful.

Now I can use AI to triage issues, strategize, and so on!

ChatGPT 4o almost gets right the piano keyboard layout, still off...

I don't see what would be the benefit of using this compared to paying for an actual stock photo.

Every time you declare a component prop as optional you are creating logical branches of conditional code to be executed.

You may be protecting your code from runtime errors, but you are not protecting from bugs. And errors are there to help you prevent bugs.

It took me a long time to get my head around the currying coding pattern. It helps me reduce function signature noise, passing down props, and fix parameters that do not change.

Now that I know I find it to be pretty useful!

Have you used currying? Do you know what it is?
Code snippet demonstrating currying. Code: const makeSentence = subject => action => object => `${subject} ${action} ${object}!` const bobAction = makeSentence("Bob") const bobEats = bobAction("eats") console.log(bobAction("likes")("pizza")) // "Bob likes pizza!" console.log(bobEats("pizza")) // "Bob eats pizza!"

Notice something weird?
