Mostly, no need to use and IDE. I'm still very much using jetbrains stuff and most agents are baked into vs code clones - claude code is cool as I don't have to change my tools

looking at osv, most of the reports on npm is due to malicious code. Is that right? I find around 85% of malware in the dataset.

You can just ship ESM now 🚀 Node.js 18 is going to reach EOL in April and Node.js 20 and newer can require(esm) so no need for dual packages anymore! 📦

“Use the best tool for the job” continues to mean “I started by assuming I’d use my favorite language and then worked backwards from there and now I want to sound objective about it”

I miss living in Australia. Paradoxically, the loneliness of not knowing anyone made me feel so free.

Ok I have the best talk idea ever, a talk so great I am sure I will get some VC reaching out to fund its topic. Now, this is a talk about nextjs (or react+node) and AI, where should I CFP it?

Yeah, this is not clear in the post, I meant "only one authenticator can be active at once" is that correct ? RE: corrupt signature: that'd be a great addition, is there a way of doing it with the CDP? Not sur I got this part really.

Vladimir de Turckheim @v2t.dev · 14/02/2025
good point, yeah this is not clear, I will rephrase this part, to clear that up - let me know if you find other things I need to correct?

When building an AI-enabled app, always ask, "Who is accountable for the decisions of that system?" If the answer is "I don't know" or "no one", I have some bad news for you

Accurate summary of my journey building an AI-based product. Right now, we’re shipping features at high speed—things that were considered impossible not so long ago, and that many would never believe are actually doable (can't wait to share them!). What’s next? (DM open if you want to see magic)
A hand-drawn, xkcd-style line chart titled “Excitement on AI Over Time.” The vertical axis is labeled “OMG Factor” and the horizontal axis is labeled “Time,” but neither axis has numeric values. The orange line starts low, rises to a peak marked “AI is awesome,” then descends to a trough annotated “Limitations everywhere,” before climbing again to the top line of the chart, labeled “UX Heaven.” At this peak, the line transitions into a dotted horizontal line extending to the right, ending with a question mark, suggesting future uncertainty.

Exclusive: The backdoor inserted in v1.95.7 adds an "addToQueue" function which exfiltrates the private key through seemingly-legitimate CloudFlare headers. Calls to this function are then inserted in various places that (legitimately) access the private key.

Code > Words. I don't believe we will ever get to a point where natural language will be as precise as coding to describe how a system must behave. But yeah, code might het higher level or with less syntax at least.

A comment on a PR marked as spam on Github with text "It looks like you're dealing with a complex pull request related to the cookie package and ensuring TypeErrors include standard Node error codes. This kind of meticulous work is essential for robust error handling and maintaining backward compatibility.

To summarize the key points:

Error Codes in TypeErrors: The pull request adds .code properties to TypeError throws in the serialize and parse functions. This allows for more granular error handling.

Testing: Adjustments to existing tests ensure that they check for both the correct error message and the new error codes.

Performance Considerations: There's an ongoing discussion about the performance implications of creating error objects when not strictly necessary, which might impact performance in deep stacks.

Conflicting Tests: Some continuous integration (CI) tests are failing or have been canceled, particularly on older https://node.js/ Node.jsversions. This needs further investigation to determine the exact cause and ensure that the changes do not break existing functionality."
