Foursquare raised about $412 million, was once valued at $450 million, and sold to ad tech company Infillion for zero dollars to every equity holder. Axios broke the acquisition on September 18, 2026 with terms undisclosed. A month later, co-founder Dennis Crowley confirmed in his Teendrama Snippets newsletter that preferred and common shareholders both got … Read more

About two months ago, we launched the Shipaton Blogging Contest as an official build-in-public partner for Shipaton 2026. Running alongside the hackathon, our contest was designed to reward developers willing to document the work behind building useful apps. Because, as we’re all well aware, there’s a lot more to building an app than writing code … Read more

A new broadcasting agreement puts three CayoTV creators at the center of the NFL’s live coverage in Spain, and it is a useful case study for anyone building media products. Conversations about live sports streaming tend to focus on rights fees and platforms. The NFL’s 2026 agreement with CayoTV in Spain stands out for a … Read more

A hacker’s threat model meets a philosopher’s skepticism. I’ll make the strongest case that AI takes over, then the strongest case that it doesn’t, and then tell you where I land and why. First, fix the question “Why would AI want to take over the world?” smuggles in two assumptions: that AI wants things the … Read more

Your application is healthy. The database is responding. The dashboard is green. A user asks the AI assistant a question, and nothing comes back. This is an awkward kind of outage because the rest of the system may be working perfectly. The model service could be slow, rate limited, unavailable, or returning an answer that … Read more

There’s a popular tourist attraction close to where I live called the Ballard Locks. It’s an old lock complex that raises and lowers boats going between Puget Sound and Lake Washington, and it also has a pretty nifty fish ladder, which is why the site attracts more than 1 million visitors annually. But there’s been … Read more

This is a story about how I spent 21 months building a trading system, wrote down what it would take for it to become a company, and then had two AI models tell me that it hadn’t. If you’ve read my last three posts, you know TopSet. It’s the system I built, mostly with AI … Read more

You’re writing your tests, your AI agent is crushing it, all use cases and edge ones are being covered, but you’ve installed an AWS SDK and now you’ll need to mock it (oh boy). After a few hours in, and a few years of life out the window, you notice that nothing you do can … Read more

I have read more AGENTS.md files than I can count, across repos I own and repos I was parachuted into. They almost all follow the same arc. Week one: 25 crisp lines, written by someone who knows the codebase cold. Month three: 80 lines, after three well-meaning contributors each added “just one rule.” Month nine: … Read more

Fhenix says its encrypted computation coprocessor, CoFHE, is now in production on Ethereum and Arbitrum. The October 21 announcement brings fully homomorphic encryption, or FHE, to applications that need to calculate with confidential balances, positions and trading strategies while using those networks for their contracts. The launch includes a dual-mode token design, two announced design … Read more

The log is held by the party under audit Agents now read customer records, open pull requests, approve releases and pay invoices. When something goes wrong, the only answer to “what exactly did the agent do?” is a log file held by the party with the strongest reason to edit it. The operator, the agent … Read more

Every engineer who has ever worked in a regulated field has a few production nightmares. In lending, one of them is being asked to explain exactly why a loan was declined eighteen months ago. What rule was in force, who approved it, what it replaced, and why. With rigid legacy systems, that turns into archaeology: … Read more

I build Loretypes, a free site with six self-discovery quizzes: Aura Color, Archetype, Moral Alignment, Past Life, Color Season and Spirit Animal. They’re for reflection and fun, not diagnosis. Past Life is openly fictional, and Color Season asks which color combinations you like rather than analyzing a photo. The quizzes themselves are the easy part. … Read more

We sent the same 4-page HTML invoice to 12 PDF generation APIs and checked every page that came back against 14 rendering checks, plus speed and file size. PDFGate and DocRaptor passed all 14, with DocRaptor using a version of the page written for its Prince engine. Everything we used, the HTML, the script, and … Read more

Meris Network has joined the Aethir ecosystem as a compute provider. Aethir runs a decentralized GPU cloud for artificial intelligence, cloud gaming, and other work that needs a graphics card on demand. Meris brings a pool of lent GPUs into that cloud. Aethir’s hosts connect their own machines, and Aethir schedules the capacity for customers who … Read more

Terra Security has launched the AI Native Cybersecurity Podcast, a new series co-hosted by co-founder and CEO Shahar Peled that brings together security leaders who are putting artificial intelligence to work on both sides of the fight. The inaugural episode features CJ Moses, CISO of Amazon, in a wide-ranging conversation about how generative AI has … Read more

I work with Claude Code, OpenAI’s Codex coding agent, and Google’s Antigravity IDE. I wanted a solution found in one session to stay found, so the next session wouldn’t have to dig it up all over again. I’m the author of KYB — Know Your Business, a shared knowledge base I built with these agents … Read more

A developer might (and if you did some right steps probably will) encounter an AI-generated summary of your product before they visit your website. Recommendations from colleagues, Reddit discussions, and tutorials help developers discover tools. AI search adds another route: developers can describe their stack, budget, and requirements, then ask an assistant for a shortlist. … Read more

The fastest path to production for open-source AI models depends on how much infrastructure you’re willing to own. If you only need a working endpoint, you can change one line of code and call open models in minutes. If the models have to run inside your own cloud, a single Docker command on one GPU … Read more

There is a simple and logical way to approach machine learning model selection. You start with many models. Then you remove the weaker candidates, keep a smaller group of promising ones, and spend your main compute budget on those. That is usually the right thing to do. But there is one risk: What if the … Read more

The sentence sounds like it was written for the customer: “Your team can launch this integration next week.” An AI tool might produce that line after reading a CRM record and a product description. The problem is that neither source proves the customer’s project is ready, the integration is available in their environment, or anyone … Read more

A revenue team adds an AI-filled field to its CRM. The first result looks useful: a concise assessment of a company’s likely buying priority. The team then adds a workflow branch. If the field says “expansion,” route the record to an account executive. That second decision changes the risk. The first step produces information; the … Read more

Self-managed Kubernetes makes sense when you want to save some of your engineering budget. With OpenStack, you still get API-driven provisioning, private networking, and standard Terraform tooling without paying for a managed control plane. A three-node k3s cluster on cloud comes at about $346/month. A comparable EKS setup in us-east-1 costs around $914/month before adding … Read more

Moxie Marlinspike, a dreadlocked squatter who sailed a $1,000 wreck to the Caribbean with bags of bricks for anchors, built Signal and the encryption guarding billions of WhatsApp and Messenger chats, then got Facebook, Google, and Microsoft to run his code. The Bricks The spare anchor is a bag of bricks. Not a Danforth, not … Read more

TIL: MTS Live is not a livestream of a Member of Technical Staff When “MTS Live” first scrolled across my X feed, I assumed it was a livestream of a Member of Technical Staff. Some ex-unicorn CEO, now humbly pair-programming at a frontier lab, broadcasting his commits. A living, breathing MTS. Live. It is not. … Read more

A revenue briefing starts as a conversation. Someone asks an assistant to summarize an account, adjusts the tone, removes a paragraph, and turns the result into a presentation. The team sees a useful document. The customer sees a statement from the business. Those are different responsibilities. A prompt can explain what to generate without deciding … Read more
