I built Obyflow, an open-source observability tool, because I kept running into the same problem: debugging an LLM application rarely looks like debugging a normal web app. A stack trace tells you where the code broke. It doesn’t tell you that the model call succeeded but the retriever returned nothing. It doesn’t tell you that … Read more

How human-led strategic alignment prevents costly localization blunders when scaling international campaigns with generative AI. As Managing Director of an international marketing agency and author of “AI: The Marketing Evolution (Adapt or Vanish)”, I see marketing teams make the same costly mistake every single week: confusing algorithmic speed with cultural comprehension. Generative AI tools allow … Read more

I grew up in the United States, so when I moved to Bosnia and Herzegovina roughly twenty years ago, the internet situation was a genuine shock. I did not expect Bosnia to have the same infrastructure as the US. That would have been an unreasonable comparison, especially at the time. What surprised me was not … Read more

You’ve spent years building an identity online. You have a username people recognise, a feed full of things you’ve posted, people who follow you, people you follow back, and enough history on the platform that leaving it would feel like leaving a small part of yourself behind. Now imagine waking up one day and it’s … Read more

Add a new payee to your bank account and try to send them money right away, and in a lot of banking systems you’ll hit something most security features never do: a wall that isn’t there to stop you, just to slow you down. The payee gets added fine. The transfer doesn’t go through, not … Read more

At ten in the morning in Tokyo, under 94% cloud cover, I needed my app’s paywall to show a clear sunset. Waiting was the obvious option. What I did instead took one command: I moved my iOS Simulator to Albuquerque, where it was 7 p.m. with no clouds at all, waited 22 seconds, and took … Read more

Stamford, CT, September 16th, 2026/CyberNewswire/–Detection engineers do not need more detections. They need their existing detections to fire earlier, on cleaner data, without paying SIEM ingest rates for the privilege. Announced during Splunk .conf26, AxoDetect, Axoflow’s detection component, now in early access, runs a customer’s rules directly in the pipeline, on clean, normalized security data, … Read more

London, United Kingdom, September 16th, 2026/Chainwire/–BASIS, the institutional-grade crypto yield and staking platform built on market-neutral execution infrastructure, is continuing to expand its institutional footprint with three new developments: an ecosystem partnership with XDC Network, a collaboration with Zypher DAO, and em-dash (Auto Earn an automated) reward restaking feature now live for BTC, ETH, SOL, … Read more

On Wednesday I wrote that of the shares coming off the SpaceX lock-up that week, only the affiliates’ tranche would leave a record — and that it was therefore the only part where “did they sell” is a question with a documented answer. So I went and read the answer. The answer is nothing The … Read more

I’m a founder who builds computer vision into physical systems, and gesture control is one of those ideas that looks finished the moment you see hand landmarks tracking on screen, and then isn’t. Drawing a skeleton on your hand feels like the hard part. It’s not. The hard part is everything between “I can see … Read more

1. What is your company in 2–5 words? Gamified bin-mapping for travellers. 2. Why is now the time for your company to exist? Sustainability has never been more front-of-mind for young travellers — but most “green” tech is preachy and dull, so it doesn’t actually change behaviour. Meanwhile, gamification and community apps have proven they … Read more

1. What is your company in 2–5 words? Creatives Takeover is a business development platform for startup founders & first-time business owners. 2. Why is now the time for your company to exist? Because there are many unoriented founders with almost no support or guidance, we want to make startup formation accessible to everyone. Unfortunately, … Read more

Every once in a while, a research report drops a number so specific and so telling that it just parks itself in your head for weeks. Wiz did that to me back in April with their State of AI in the Cloud 2026 report, and I’ve been meaning to write about it ever since. The … Read more

An investigation into intermittent gateway failures, NGINX worker restarts, and the metrics that exposed the pattern An API gateway failure does not always begin with an unavailable upstream service. Sometimes the gateway itself loses the ability to select a target, and the resulting error makes the upstream look guilty. We use Kong Gateway as part … Read more

Trust has always been central to financial markets. But as trading increasingly moves online, the meaning of trust is changing. For digital trading platforms, credibility is no longer built through physical branches or long-standing brand recognition alone. It is increasingly shaped by regulation, technology, transparency, and the quality of the user experience. Opo, a global … Read more

SquaredQ turns a subscription into a live cloud deployment, connecting selected strategies, a private server, and the investor’s existing brokerage account inside one operating environment. Most subscribe buttons are the end of a sales process. This one starts a machine. Clicking subscribe to an algorithm sounds almost too easy. A payment is accepted. Access is … Read more

Cardinality is a consequence of how many dimensions you index your readings by. Here is where the curve bends, measured, and what you can do about it without leaving Postgres. Someone adds a firmware_ver column to the sensor table. It is one line of DDL, and it clears review in a minute. Two weeks later, the ingest … Read more

Security teams in the manufacturing sector face persistent operational demands. Recent ANY.RUN data shows their workloads are roughly 22% higher than those in other major industries. To get an insider’s view on how teams navigate these industry demands, we sat down with Philipp Z., Security Lead at a leading German manufacturer. He shared how replacing complex manual analysis with … Read more

The technical part of adding a subscription is only half the work. The uncomfortable part is deciding what the user is actually paying for. Slovo teaches Russian through one daily word, spaced review, widgets, pronunciation, and short reading. Its entire philosophy is low pressure. An aggressive paywall after a six-step onboarding would contradict that philosophy … Read more

Amana is a solo-built iOS app that draws the sky outside your window — from your time, your location and the position of the sun — and then tries to get you to put the phone down and go look at the real one. It is on the App Store. I already wrote about why … Read more

I had been wanting to participate in a hackathon for a while. DevPost contacted me via their newsletter, and from there things escalated quickly. Many of the competition tracks required publishing a fully functional app to common app stores. For this reason, I chose to participate in the Next Gen track. Not having to publish … Read more

I spent most of my career building data systems at enterprise scale. Big warehouses, big pipelines, models trained on tables that other people had already cleaned before they ever reached me. I did not realize how much that setup was cushioning me until I strapped a sensor to a tennis racquet and tried to make … Read more

A few months ago I realized that as the code and modules inside the structure we’d built kept growing, it was starting to become a problem, and developing with AI was getting really hard. I’d ask Cursor or Claude Code to make a very simple change to a frontend module. At first glance it looked … Read more

https://x.com/karpathy/status/1617979122625712128?embedable=true At some point in the last year, I noticed I had stopped writing bash scripts. It wasn’t an explicit decision I made; it just happened organically as the small automations I used to script became skills instead. The deterministic parts still end up as commands, but now they sit inside a procedure that an … Read more

DeFi staking protocols appear simple from the outside: deposit tokens, wait, and receive rewards. The difficult part is making the accounting behave correctly when multiple users are staking, withdrawing, claiming rewards, changing reward rates, and interacting with a reward pool that contains a finite number of tokens. I built StakeVault to explore these problems in … Read more

Have you ever asked an LLM in chat what seemed like a simple question, then watched as it reinvented fire, the wheel, and quantum physics to tell you how far Scotiabank Arena is from the Toronto airport? AI agents, like Claude Code, Codex, OpenCode, and OpenClaw, can do that, too. But their users explicitly encourage … Read more
