+10000 the safety rules to manage this new ecosystem isn’t here yet and is critical. We’ll need safe ways to share these new artifacts (skills, plugins, MCP …)

From curl | bash off the internet…
…to docker run some random image…
…to /plugin install in coding agents.

Same vibes, bigger blast radius. Supply chain management for plugins, anyone? :)

Part 1: My Life Is a Lie How a Broken Benchmark Quietly Broke America

This is an insightful but deeply upsetting article about why everyone in the US feels poor, and why the current political situation emerges as a direct result.

The recording is available and, as expected, it is exceptionally good! It will genuinely ignite (or re-ignite) your enthusiasm for being an engineer! Thank you, @bcantrill.bsky.social

A Retrospective Survey of 2024/2025 Open Source Supply Chain Compromises Project compromises have common root causes we can mitigate: phishing, control handoff, and unsafe GitHub Actions triggers.

To implement robust mitigations across Geomys, I did a survey of open source project compromises in 2024/2025.

Three root causes dominate: phishing, control handoff, and unsafe GitHub Actions triggers. All three can be systematically avoided.

🏷️ Reason #3.7.2 why it's critical to clearly and publicly define your #OpenSource project #Governance, for code, distributions, trademarks, and domain names.

And, of course, not breaking norms and cosplaying a public charity while bowing to a sole sponsor over the community. 😢

The Register wrote a story about a single maintainer open source project, I think it's shameful and upsetting

So I wrote a blog post about it

An absolutely ridiculous amount of open source is one person projects. I have the data to prove it

What’s a technology that you think is overhyped?

I’m going to give a sideways answer to this, which is that the venture capital business model needs to be understood as requiring hype. You can go back to the Netscape IPO, and that was the proof point that made venture capital the financial lifeblood of the tech industry.

Venture capital looks at valuations and growth, not necessarily at profit or revenue. So you don’t actually have to invest in technology that works, or that even makes a profit, you simply have to have a narrative that is compelling enough to float those valuations. So you see this repetitive and exhausting hype cycle as a feature in this industry. A couple of years ago, you would have been asking me about the metaverse, then last year, you would have asked me about Web3 and crypto, and for each of these inflection points there’s an Andreessen Horowitz manifesto.

It’s not simply that one piece of technology is overhyped, it’s that hype is a necessary ingredient of the current business ecosystem of the tech industry. We should examine how often the financial incentive for hype is rewarded without any real social returns, without any meaningful progress in technology, without these tools and services and worlds ever actually manifesting. That’s key to understanding the growing chasm between the narrative of techno-optimists and the reality of our tech-encumbered world.

He has refused his Assent to Laws, the most wholesome and necessary for the public good.
He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners.
He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary powers.
He has made Judges dependent on his Will alone.
He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our people, and eat out their substance.
He has affected to render the Military independent of and superior to the Civil power.

🇺🇸Happy Fourth of July🇺🇸 This year, I'm wearing my 𝐑𝐞𝐬𝐢𝐬𝐭 shirt to show my patriotism. I'm reading the declaration of independence as I always do on this occasion. Several of King George's offenses against the colonies resonate this year. Here they are, verbatim:

I will be damned if I allow a bunch of Confederate-waving January 6th apologists give the American people a lecture on flag waving.

There is ZERO reason to enter an argument about patriotism with people who still worship traitors to America 150+ years later.

They. Are. Breaking. The. Law.
