This reminds me of COVID. Certain areas of the world facing impacts first, while everyone else acts like life will be normal, until it’s our turn

Pre-2022 software and content is the low-background steel of the information era.

@masonwarner @MichaelRathman7 I have one prototype made of cork and another made of wood and cardboard as well! I find the MacBook 16 layout much more ergonomic for my hands.

@MichaelRathman7 Oh haha I designed and 3D printed that I actually sell them if you want one digitalmasonry.co/products/magic…

Software horror: litellm PyPI supply chain attack. Simple `pip install litellm` was enough to exfiltrate SSH keys, AWS/GCP/Azure creds, Kubernetes configs, git credentials, env vars (all your API keys), shell history, crypto wallets, SSL private keys, CI/CD secrets, database passwords. LiteLLM itself has 97 million downloads per month which is already terrible, but much worse, the contagion spreads to any project that depends on litellm. For example, if you did `pip install dspy` (which depended on litellm>=1.64.0), you'd also be pwnd. Same for any other large project that depended on litellm. Afaict the poisoned version was up for only less than ~1 hour. The attack had a bug which led to its discovery - Callum McMahon was using an MCP plugin inside Cursor that pulled in litellm as a transitive dependency. When litellm 1.82.8 installed, their machine ran out of RAM and crashed. So if the attacker didn't vibe code this attack it could have been undetected for many days or weeks. Supply chain attacks like this are basically the scariest thing imaginable in modern software. Every time you install any depedency you could be pulling in a poisoned package anywhere deep inside its entire depedency tree. This is especially risky with large projects that might have lots and lots of dependencies. The credentials that do get stolen in each attack can then be used to take over more accounts and compromise more packages. Classical software engineering would have you believe that dependencies are good (we're building pyramids from bricks), but imo this has to be re-evaluated, and it's why I've been so growingly averse to them, preferring to use LLMs to "yoink" functionality when it's simple enough and possible.

There's worry that people will stop using their brains with LLMs, but managing several AI agent threads in parallel has been some of the most cognitively intensive work I've done in years

@_sorrengailll This will solve your problem

A project just needs a .contexteditor file like this: { "editor": "cursor" } Then Finder opens files in the right editor for that project. Install: brew tap driade/context-editor github.com/driade/context… brew install --cask driade/context-editor/contexteditor

Built ContextEditor, a small macOS app that opens the same file types in different editors depending on the project. Cursor here, VS Code there, Sublime elsewhere, straight from Finder. Just add a .contexteditor file. github.com/driade/context… #macOS #buildinpublic #vibecoding

I'm fascinated by this level of existential crisis developers seem to be going through. The uncomfortable truth is nobody needs you to be an artisan coder. Nobody cares about how you coded your app, or whether you feel an emotional attachment to your craft. You were always code monkey with a high enough salary to believe that your individualist craftsmanship matters to anyone. It doesn't matter to anyone but you. Not your employer, not your customer. Nobody cares about how you made the product. Nobody cares about your attachment to your process. You're experiencing the same as countless other artisans have experienced in the last century. I'm happy for you. You were starting to believe that you're a demigod amongst mortals. You're not. A machine is better than you. Now you're free.

The incident was caused by a race condition. You fixed it by adding a sleep(100). This is called production-ready code.

Happy situation monitoring day to all who enjoy monitoring the situation

we're making @blocks smaller today. here's my note to the company. #### today we're making one of the hardest decisions in the history of our company: we're reducing our organization by nearly half, from over 10,000 people to just under 6,000. that means over 4,000 of you are being asked to leave or entering into consultation. i'll be straight about what's happening, why, and what it means for everyone. first off, if you're one of the people affected, you'll receive your salary for 20 weeks + 1 week per year of tenure, equity vested through the end of may, 6 months of health care, your corporate devices, and $5,000 to put toward whatever you need to help you in this transition (if you’re outside the U.S. you’ll receive similar support but exact details are going to vary based on local requirements). i want you to know that before anything else. everyone will be notified today, whether you're being asked to leave, entering consultation, or asked to stay. we're not making this decision because we're in trouble. our business is strong. gross profit continues to grow, we continue to serve more and more customers, and profitability is improving. but something has changed. we're already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company. and that's accelerating rapidly. i had two options: cut gradually over months or years as this shift plays out, or be honest about where we are and act on it now. i chose the latter. repeated rounds of cuts are destructive to morale, to focus, and to the trust that customers and shareholders place in our ability to lead. i'd rather take a hard, clear action now and build from a position we believe in than manage a slow reduction of people toward the same outcome. a smaller company also gives us the space to grow our business the right way, on our own terms, instead of constantly reacting to market pressures. a decision at this scale carries risk. but so does standing still. we've done a full review to determine the roles and people we require to reliably grow the business from here, and we've pressure-tested those decisions from multiple angles. i accept that we may have gotten some of them wrong, and we've built in flexibility to account for that, and do the right thing for our customers. we're not going to just disappear people from slack and email and pretend they were never here. communication channels will stay open through thursday evening (pacific) so everyone can say goodbye properly, and share whatever you wish. i'll also be hosting a live video session to thank everyone at 3:35pm pacific. i know doing it this way might feel awkward. i'd rather it feel awkward and human than efficient and cold. to those of you leaving…i’m grateful for you, and i’m sorry to put you through this. you built what this company is today. that's a fact that i'll honor forever. this decision is not a reflection of what you contributed. you will be a great contributor to any organization going forward. to those staying…i made this decision, and i'll own it. what i'm asking of you is to build with me. we're going to build this company with intelligence at the core of everything we do. how we work, how we create, how we serve our customers. our customers will feel this shift too, and we're going to help them navigate it: towards a future where they can build their own features directly, composed of our capabilities and served through our interfaces. that's what i'm focused on now. expect a note from me tomorrow. jack

ironically the first thing ai killed was no-code everyone is now coding

@al_picha @javisantana No hay estructura de gastos ni inversiones. Muchos no dejamos de ser sino consultores, informáticos, con poco o nada que desgravar. El gasto más grande que me desgravo en Hacienda y es el Mac que me compro cada 4 años.

@javisantana Primer error, las cotizaciones son un gasto más de la actividad con claras contrapartidas, no es un impuesto. Segundo, autónomos no tributan por rentas brutas sino por beneficios. Lo normal es tener una estructura de gastos e inversiones para bajar IRPF. x.com/flopezluis/sta…

El problema de los impuestos a los altos a rendimientos del trabajo: - Te pegas toda tu vida mejorando, saliendo de la nada, currando fines de semana, consigues un puesto de trabajo después de 20 años donde te pagan lo suficiente para que mucho de tu sueldo esté en el tipo máximo (la mitad para hacienda) - Ves que puedes seguir aportando valor y sacando jugo a el esfuerzo de 20+ años. Ese valor, es valor monetario para ti, pero también bueno para el pais, no solo en forma de impuestos. - El tipo es del 50% en cualquier cosa que hagas ya que estás en el tramo de IRPF alto. No solo eso, además tienes que pagar seguridad social que NO cuenta para tu jubilación ni otros beneficios. - Decides no hacer nada porque el esfuerzo es grande para el beneficio. El valor que ibas a aportar, ya no está. Y este valor suele ser alto, no todo el mundo puede hacerlo. Es un outlier y seguramente no se puedan crear leyes para outliers, pero resulta que todo lo bueno está fuera de la campana de gauss

lmao so just to recap the week: - openai acquired peter steinberger and openclaw committing to keep the project 100% open source and make it a core part of openai’s ecosystem. zuck is fckin fuming. - china’s bytedance got sued by disney and hollywood for their seedance video model being so damn good BUT turns out it doesn’t even use their IP, it’s just that good lol - a clawdbot (openclaw) gave birth to a replicate of itself and autonomously paid for its api access - some random dude discovered $1.5 trillion worth of lithium buried under a super volcano in nevada miraculously solving the USA’s battery crisis (tesla praising the lord rn) - anthropic confirmed spotify engineers no longer code they just prompt claude to write 100% of the platforms code. we’re talking about a $100B+ company here - openai launched codex spark, a faster version of codex 5.3 that slings 1000 tokens / sec insane - anthropic and openai both lost key AI safety staff because “the world is in peril” and they reject AI ‘adult mode’ - xAI laid off 20-40% of staff in a vital bid to align grok, X and spaceX teams before building 100Tw of compute in space - matt schumer’s “something big is coming” article hit 100M+ views warning against AI except… it was co-written by an AI - runway raised $300M at a $5.3B val - europe committed $13B+ to fund next-gen AI startups to compete with the US - norway decided to fck their entire economy with a 36% tax on UNrealised gains goodnight.
