@unclebobmartin Time for a new book or video series !

My brain is reeling with the implications. I keep having these revelations and I'm beginning to wonder when they will stop. It turns out that property testing is yet another hardening technique that the agents can profitably engage. Agents can determine whether a function is appropriate for property testing, and can specify the range and domain of those tests. They can implement them quickly, run them, and fix any detected issues. I just found two production bugs this way. Property testing is going to be part of my normal practice, along with Crap analysis, Function mutation, acceptance test mutation, Dry analysis, etc.

@Pragmatic_Eng @ahejlsberg Wish he had continued evolving Delphi.

A Sun lawsuit accidentally created C# and .NET. Anders Hejlsberg(@ahejlsberg) - creator of C#, TypeScript, Turbo Pascal - tells us the unique origin story: Microsoft learnt the hard way not to bet on technology licensed from a competitor: “Well, development of J++ went great until the big Sun/Microsoft lawsuit got in the way. Now we're talking about business. It had nothing to do with technical, but it effectively meant that Visual J++ was never going to be a product that companies would make a bet on because they full well knew that you're not going to ride your app in a language that has been enjoined by a judge in San Jose. We kind of realised at that point that, maybe it's not a great strategy to place your development platform bet on technology that's licensed from a competitor.” They already knew what devs loved and hated about Visual Basic and C++: “Microsoft's main development products at the time were in two camps. There was Visual Basic, rapid application development, loved by everybody because it was so easy to build apps, but performance-wise it had problems and extensibility-wise it wasn't so great. To write new components, you had to write 'em in C++ and whatever. And then we had C++ with MFC and power and expressiveness.” .NET and C# were born from previous learnings and the need for proprietary tech: “Really, what people wanted was both. They wanted something that rolled both of those up. And then they also wanted modern things like garbage collection that, say, Java had, for example, and exception handling and a more object-oriented, component oriented way of building your apps. And all of that was part of the genesis that led to .NET and to the C# language.”

@tannerlinsley @ErfanEbrahimnia It’s time for a JavaScript standard library

@ErfanEbrahimnia Oof. I wish these kinds of attacks were limited to literally any kind of library architecture, but this is more fundamental to the NPM ecosystem / CI / publish processes. No one is immune.

wtf TanStack?? I was promised security incidents were a Next.js exclusive thing now I have to refactor my entire app again??

@_trish_xD Clojure seems like a natural fit here

wise words from the best systems engineer I've worked with: "two things that make code actually maintainable: 1. reduce the layers a reader has to trace 2. reduce the state a reader has to hold in their head" applies to every codebase. always.

@elliott87875332 @SunvMikey Agree. I bought ARKG but was too early

What is the next bubble? In the last 18 months we've had quantum, nuclear tech, rare earths, drones, ai infrastructure, photonics. Im thinking robotics? What else is there? Trying to front run the crowd

@unclebobmartin I named my clawdbot HAL !

Do you sometimes feel like Dave Bowman, talking to HAL?

@Kableado @seatedro Didn’t love lcl. Time for something more modern.

@MikeMargerum @seatedro Anything wrong with Lazarus? lazarus-ide.org

qt is genuinely great. i was able to get it to work on both linux and mac with basically no effort. and it's not electron slop. why do people still use electron slop?

@ibuildthecloud I’m seriously considering rail and I’ve done react, angular, .ner, and go up till now. AI likes opinionated battlers included frameworks Second choice would be go , HTMX, and alpine (or hyperscript). Nextjs looks like a bag of hurt

This is not what I wanted to do. I have to dump react. I just can't take it anymore. The reason I went with React was the idea that I could delegate more to AI and pay less attention to it. And that has failed miserably. I really have to keep close tabs on what AI is doing and if that's the case I'm not going to use React.

@seatedro If I didn’t have a day job I’d build a new vcl style framework that ran on top of freepascal . One that was multi platform . Claude is probably pretty close to being able to do this . Object pascal has a lot of nice features that make it the best choice for desktop development

@MikeMargerum i mean you could always use gpl

@MilkRoadAI Can’t stop seeing this kid

The CEO of a $95 billion company just said something that should TERRIFY every software executive on the planet. Patrick Collison, the man who built Stripe, went on TBPN last week and compared the entire software industry to frozen food. His words: "Software has been created years beforehand, freeze-dried, and then prepared at the moment of consumption." That era is ending. His new model for software? Pizza. Fresh pizza, made to order, right then and there. Exactly what you need, the moment you need it. That is the future Collison sees for all software. What does that actually mean? It means AI agents will build you custom software in real time. No subscriptions, bloated dashboards and one size fits all. Software cooked for you, that moment, then gone. This is already happening. Anthropic launched Claude Cowork in January. Within weeks, $2 trillion in software stocks evaporated. IBM had its worst trading day in 26 years, legalZoom dropped 20% and the entire SaaS sector is in freefall. They're calling it the SaaSpocalypse. The old software model was simple, spend millions building a product, sell it to everyone and collect subscriptions forever. Fixed cost, infinite monetization and winner takes all. That game created trillion dollar companies: Salesforce. Adobe, Oracle, Microsoft. Collison says that game is now breaking. Why? Because AI introduces real cost at every use. Inference costs, custom creation costs, every single interaction has a price tag. No more build once, sell forever and he called it the non-Walrasian software regime. Translation: The winner take all economics that built Big Software are collapsing. When every user gets custom software built on demand, there is no single winner. There are thousands of winners or none. Think about what this does to pricing. No more $50/seat/month or enterprise contracts worth millions. Instead, you pay per task, outcome and for what the AI actually built you. The entire revenue model of SaaS is being rewritten. Klarna already ripped out Salesforce and replaced it with AI. Cursor ditched its paid CMS and built a replacement from scratch. Companies are doing this now. The dominoes are falling. The entire industry is being rewritten in real time.

@kurtknapp @matteopelleg You’re missing the integration part.

@matteopelleg They won't get that anyway?

I’m now convinced that the biggest winner of the AI race will be Apple. They will acquire Anthropic and put an AI model that can run on ~32GB of RAM in every device. It will be private, local, have perfect memory, access to all of your files and it will cost $0. The real moat was owning the hardware.

Forget $appl making money on $1500 phone. They're selling $10k ai compute machines like hot cakes.

@startupideaspod Like the idea of markdown with links but im failing to understand why Obsidian is needed. doesn't markdown support linking of files?

@unclebobmartin That the great part. It writes the tests for me to make sure the code works.

I'm beginning to think that the three laws of TDD are necessary to keep Claude from going off the rails. It's slower, to be sure, but that may be a cost worth accepting.

@GenTXer2 #1 imo

@david_eng_mba @BitcoinSapiens How did it go to 15k then in 2023?

This graph is extremely important with Bitcoin near ~$73K. Pricing below Bitcoin’s thermodynamic floor is economically unsustainable over time because it forces marginal producers offline. As miners shut down, sell pressure collapses, supply tightens, and the system removes supply until price can no longer remain below cost. As can be seen on the graph, the floor rises over time. Great opportunity. #DYOR

Bitcoin has never fallen below its electrical cost. Today that floor is $71,000.

@atShruti How does Clawdbot drive a browser from a headless AWS instance?

This is so scary we were attacked 7,922 times over the weekend after using Clawdbot. There are hundreds of Clawdbot servers exposed to the open internet this week. Credential dumps. API keys in plaintext. The thing people missed is that you're not the only input to your agent. Every email it reads, every calendar invite, every webpage it visits is content someone else wrote. Random person DMs you? That's now input to a system with shell access. If you're going to use it, treat it like onboarding a contractor. Dedicated machine or VPS. Separate accounts. Minimal permissions to start. Run it behind Tailscale so it's not exposed to the public internet. Run clawdbot doctor regularly and let it fix itself. The bigger idea is that agents need their own identities. Own devices, own accounts, own credentials. Not piggybacking on yours. Also please stop buying Mac Minis for this. You can run it on AWS free tier in five minutes or a $5 VPS.
