The value of tests is when the fail they show you of something you broke that you didn't realize. 80% (likely more, but I don't know how to measure) of the tests I write could safely be thrown away because they fail again - but I don't know which tests will fail and thus inform me that I broke things.

The system I'm working on has been in production for 12 years - we have added a lot of new features over those years. Many of those needed us to hook into existing code, tests help us know that we didn't break something that used to work.

Maybe that helps answer the question of why they are important to me. They might not be to your problems.

Geothermal needs either a horrifically expensive vertical bore hole going down a few hundred metres, or a good acre of land for laid-down piping. I have neither the money nor the horizontal space. So I am thinking something compact that needs to go only about 6-10m vertically into the ground (so I can hide it fully underground with about a metre of soil on top), and take up the horizontal space of 4 parked cars. I have more than enough room and cash to have that cube of space dug out.

And being on an alluvial plain, if I filter out all the rocks larger than a pea, a good 90+% of what is dug out can immediately be trucked away.
Moltbook: Hype for Midwits
by cadabrabra | 2026-02-02 17:19:19+00:00
For how long will the public continue to fall for the illusion of cognition? I guess for as long as the elites keep deploying tricks like Moltbook. Riddle me this: If agents were powerful enough to converse and plot against humanity, then why couldn’t McDonald’s Or Taco Bell replace their drive thrus with them? Why couldn’t any company replace any job function with agents?

The public is disgraceful in its lack of critical thinking. It trusts proxy measures rather than direct demonstrations of AI’s abilities.

Well, given that it is an equity sale, split still feels like it is the prorated amount so that alphabet continues to own its percentage - not more not less.

Obviously you're entitled to your view, but I don't think it's that kind of finance model right now - it's far too speculative and the upside too unknown to be adjusting for small amounts on risk models.

Yeah same in fact that's how I discovered Termux. I had an rsync.net account and thought that since rsync and ssh are so ubiquitous it should be simple to set up back-ups from my android phone. Boy was I wrong. The android apps that support rsync were all janky or suspiciously closed. Termux + rsync + Termux API's job scheduler does the trick. I think it's a bit of a drain on my phone battery but I won't complain given I own my photo back-ups from top to bottom (though I rent from rsync.net)

In my experience if I want to living in a bikable/walkable/transit oriented area, I have to move there. I think expecting this sort of stuff to come to you is too much, especially since most city centers have good transit options.

That said this is a tech forum, and while I don't think Waymo will be the only solution the tech is quite impressive and it's likely going to change how society works. Most people don't want to take public transit, they want to take a car and this is a much better solution for them. Forcing people to bike when they don't want to seems like bad form imo.

The repeated failing of the EU (90s+) was under-appreciation of the economic / political / military pressure that could be brought by constraining key material and energy supplies.

If the EU (specifically Germany) had more presciently modeled out Russian foreign policy with a shift to increased EU reliance on Russian natural gas, there were steps it could have taken.

E.g. building in a tripwire for territorial invasion with the express responses of cutting Russian gas purchases on day 1, freezing Russian assets and access to European banking, and building storage / LNG terminals

Had the EU done this, loudly, Ukraine likely wouldn't have been invaded.

The EU's biggest mistake was presuming that everyone took the international order as inviolate as it did. (China, Russia, the US)

Mondrio | Software Engineer (Founding Team) | REMOTE (Brazil) | 3-Month Trial-to-Hire

B2B SaaS pricing is still guesswork. We’re building the AI-powered monetization operating system to fix it. We are pre-seed, lean (4 people), and shipping to live customers.

The Experience: This is a unique "fast-track" for an ambitious junior/mid-level engineer. You’ll skip the corporate ladder and learn to build an AI-native company from the ground floor. You will own features end-to-end—no managers, no layers.

AI-Native Workflow: We are all-in on Claude Code for scoping and shipping. You get a seat on Day 1. If you aren't already 10x-ing your output with AI tools, we’ll teach you. It’s the most essential skill for the next decade of engineering.

The Work:

Integrations: Build OAuth 2.0 flows and data sync pipelines for pilot customers.

Northstar Module: Build a strategic intelligence module from scratch (DB, Backend, Frontend integration. We have most of designs already).

AI Personas: Use LLMs to turn raw customer data into actionable pricing strategy.

Stack: Python 3.12 (Typed), FastAPI, MongoDB/Beanie, React/TS, Gemini/Claude, Claude Code, Google Cloud, Docker, Pulumi

Who You Are: You write clean, typed Python and can navigate a React component. You use AI tools (Cursor/Copilot) to move fast but remain the pilot. You care about the "Why" behind the product.

Process: Intro call → Technical session → Founder chat. Decision in ~7 days.

Apply: Send a link to something you’ve built to manon@mondrio.com

"OP here. I built this because I noticed two problems scaling my internal RAG tools:

Redundant Costs: Users asking the same questions (or slight variations) were costing me redundant tokens.

Compliance Anxiety: I didn't want PII (names, emails, IDs) hitting OpenAI/DeepSeek servers directly.

I looked for existing gateways but most were heavy Docker containers (requiring a VPS). I wanted something 'Zero DevOps' that could run on the Edge.

The Solution: It's a lightweight Gateway built with Hono running on Cloudflare Workers.

Smart Caching: Hashes the prompt body (SHA-256) and serves from KV if it's a hit (<50ms latency).

PII Shield: Uses Regex/NER to replace sensitive data with placeholders ([EMAIL_1]) before forwarding to the LLM.

Re-hydration: When the LLM responds, the Worker puts the real data back into the response, so the user context remains broken.

It's open-source (MIT). I'm currently looking for feedback on how to implement semantic caching (Vectorize) to catch non-identical prompts.

Happy to answer any questions about the implementation!"

The corporate culture shifted steadily at Apple following Jobs’ death. It was obviously a turning point for the company and while the change wasn’t overnight, in the ten years that followed, a lot of people moved on, because (obviously) Apple will never be Apple under Jobs ever again.

Because many of them had been with the company a long time (and were thus old), they were replaced by mostly younger people who had less experience with what makes Apple Apple.

In my personal opinion, the soul went out of the company. It wasn’t immediately when Jobs died - to his credit it took more than a decade for the momentum of his vision to die.

Today, Apple is just another multinational, nickel and diming their customer base for services revenue, cooperating with the totalitarian surveillance state (not that they have much choice in the police states of the PRC and USA in which they operate/can’t fight city hall), shipping incrementially improved products (and incrementally worse software), and misleading their customers with clever marketing. It’s just business. It used to be something else entirely.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

We're looking to build our in-person team in NYC but also open to remote!

I had my first go at using it (Github Copilot) last week, for a simple refactoring task. I'd have to say I reasonably specified it, yet it still managed to to fail to delete a closing brace when it removed the opening block as specified.

That was using the Claude Sonnet 4.5 model, I wonder if using the Opus 4.5 model would have managed to avoid that.

The DNA removal comment was as joke; sorry if that wasn't clear.

No system is self-perpetuating, per the Second Law; all need other inputs. What makes the machinary yield the ~same results ~every time is DNA.

> In the RNA world hypothesis, such self-catalyzation was the origin of life; and by the time DNA evolved, it did so within a running biological system and as merely one component of cellular replication.

Is there evidence of that? Afaik the earliest evidence is prokaryotes ~~3.5 billion years ago, and prokaryotes generally have DNA.

Waypoint AI | Senior Backend, Fullstack, Frontend | Prague + REMOTE (CZ) | Full-time | Equity

We're building Chip — an AI support engineer that autonomously triages, routes, and resolves complex technical support cases. Think: a teammate that reads every Jira ticket, every Intercom thread, and every runbook, then actually acts on them.

Czech-American B2B startup, raised $3.1M. Already in production with Volvo, ClickHouse, and others.

We're a small eng team where early architectural decisions still matter. We use AI daily as a collaborator (Claude Code) — not as a gimmick, but because it genuinely makes us faster. We value craft, ownership, and shipping in small slices.

Stack: Django + Django Ninja, Postgres, Dramatiq (background jobs), React/Next.js/TypeScript/Tailwind.

Hiring for three roles:

Senior Backend Engineer (AI Systems) — Own APIs, data pipelines, and durable workflows. LLM product experience (evals, cost/latency, vector search) is a plus. https://mywaypoint.ai/open-positions/senior-backend-engineer...

Fullstack Engineer — Backend-heavy with enough frontend to be dangerous. End-to-end ownership from schema to UI. https://mywaypoint.ai/open-positions/fullstack-engineer

Frontend Developer — Build interfaces that make complex AI feel simple. React/Next.js/TS/Tailwind. Product-minded, not just pixel-pushing. https://mywaypoint.ai/open-positions/frontend-developer

Office in Prague 7 (Holešovice), remote-friendly. Competitive CZ-market comp + meaningful equity.

To apply: joinus@mywaypoint.ai — include a project you shipped end-to-end and how you use AI tooling in your workflow. Mention HN.

I really wonder what is happening inside where Microsoft does not release a single nice or product in years.

What would happen to the morale? What would people proudly say “this is what my company built”?

I’m trying to understand how they screwed up the AI thing so much.

There’s so much innovation, creativity possible using AI, especially as an integration in the OS.

I actually have like, four different ones... :^))) I'm a bit of a keyboard fiend.

The main one I use with my Android tablet specifically is a no-name brand, knock-off "magic keyboard"-style folio case that I got on AliExpress for like, 45 USD. I ordered the English layout, I received the Spanish one (which is mostly the same but had additional legends for Spanish characters). Le sigh. It's AliExpress, I didn't bother contacting support.

For my phone, I have a really old Zagg one that was originally for an iPad. The iPad has long since died but the keyboard lives on. Woo!

The main keyboard I type on all day at my desk is a Logitech Pebble K380s. It can store three different connection profiles, which can be either Bluetooth or Logi unified receiver. So I have one of those profiles set to connect to my Pixel 8 via Bluetooth (typing from that now). Makes toggling back and forth between that and my desktop very smooth.

On a "real keyboard" (like this K380s) there's a dedicated Esc key. Most tablet folio cases don't have Esc. I found an app called "External Keyboard Helper Pro" that lets me rebind Caps Lock to Esc. That makes Neovim much more pleasant.

In America some non-Italian mafias do get labeled as "a mafia" by the FBI. Generally the distinguishing factors between a "gang" and a "mafia" in FBI nomenclature is scale, sophistication, and organization structure/principles. In general, it being a "family operation" (trusting blood family over government or family as government) is a large factor, and often the "omerta" principle is a requirement (that's a strong, core collective binding to secrecy; "omerta" if held as a strong principal "breaks" the prisoner's dilemma game as a law enforcement tool). The Cornbread Mafia, taken apart by the FBI in the 1980s, is one interesting example: https://en.wikipedia.org/wiki/Cornbread_Mafia

Does anyone know of an X server or Wayland compositor app for Android that gives each window its own Android window (or whatever they're called on Android)? IMO that'd mix perfectly with Termux for GUI apps.

Yes, I know Termux-X11 exists but that app is a single Android window (again, I'm not sure if that's the right term) for all X windows. I'm wondering if there's an app that creates an Android window for each X window.

Based on my 20 years of experience, the vast majority of developers do not possess those skills.

I'd guess that only 10% of them actually do. In order to have those skills, you need good user sense, good business sense, good negotiation skills, good communication skills. These skills align more with the product manager to be frank.

Of course, the best people are still going to be those who have the technical chops and business sense. They'll be amplified more in this era.

It makes particular sense for vertically integrated conglomerates like Amazon-Whole Foods which owns Zoox.

I buy Whole Foods French fries shipped to the store via Amazon logistics and purchase those at Amazon owned Whole Foods, at a discount via my Prime membership on my Amazon credit card which is processed on AWS infrastructure and I ride home on an Amazon owned Zoox that also runs on AWS infrastructure.

Amazon owns so much of the profit margin across that stack that they can afford to give rides away for example.

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering
