Hackernoon

I spent over twenty years in commercial banking in Belgrade, Serbia. My entire professional life revolved around balance sheets, credit risk, debt restructuring, and cash-flow statements. When you spend that long reading financial reports, you develop a permanent allergy to marketing spin. You learn to ignore what executives say on stage and look exclusively at … Read more

On September 3, 2026, two launches happened an ocean apart. In London, Uber riders could be matched with a Ford Mustang Mach-E driven by Wayve’s neural network, with no HD map underneath it and a safety driver still in the seat. In Austin, Tesla started charging fares for the Cybercab, a car with no steering … Read more

The Challenge of Topology-Aware Observability in NeoClouds Imagine a customer training a model on hundreds of GPUs. The job has not crashed. The GPUs are visible, the servers are online, and no major network outage has been reported. Yet training is taking longer than expected. The ML team sees workers waiting during synchronization. The GPU … Read more

Cursor has changed a lot in a short time. On October 12, it moved its cheapest plan to Grok-only models, and on November 12, OpenAI will stop providing its models to Cursor. Teams that chose Cursor for access to the best models now have reason to ask whether that access will last. One of Kilo’s … Read more

Codex Cloud lets you give a coding task to an agent running in a remote environment. It can read the project, edit files, run commands, and prepare changes for review on GitHub. I started my walkthrough with small JavaScript examples. Asking Codex to explain the project first gave me enough context to follow up with … Read more

Garbage collection is one of the most useful features of modern managed programming languages. It reduces memory-management complexity, automatically reclaims unreachable objects, and eliminates many common manual memory-management errors. However, garbage collection introduces a performance consideration that becomes especially important in latency-sensitive applications: memory allocation is fast, but managing the accumulated allocations can create unpredictable … Read more

Ruwiki offers a useful case study for one of generative AI’s less obvious problems: a system can retrieve fresh information in seconds, scan multiple documents and still confidently reproduce an error that has been circulating online for years. The failure does not necessarily begin with the model. It can begin one layer below, in the … Read more

A visitor submits a contact form and sees “Success.” What has the website owner learned? Only that the visitor-facing page displayed a confirmation. The owner has not yet established whether the corresponding inquiry can be found where the business expects to receive it, or whether anyone can reply to it. Treating those as separate checkpoints … Read more

An end-to-end encryption test should do more than prove that one browser can decrypt what another browser encrypted. It should impersonate an active relay, change authenticated metadata, move ciphertext into the wrong context, attempt a downgrade, interrupt state transitions, and then verify two outcomes: every attack is rejected, and honest communication still works afterward. This … Read more

Can we run it on our own machine?” is now one of the first questions teams ask about an open-weight model. Data that cannot leave the building, a predictable monthly bill, or simply the wish to stop depending on a provider: the reasons vary, but the next question is always the same. Which hardware, and how … Read more

Three things happened in the first quarter of 2026 that belong in the same sentence. In January, a startup called Tensor stood on the CES floor with a car it says you can own, that drives itself at Level 4, and that folds its steering wheel away when it does. In the same month, Mercedes-Benz … Read more

Every backend engineer eventually hits the performance wall. Your application is handling moderate traffic, but suddenly latency spikes, CPU usage hits 100%, or database connections timeout. The knee-jerk reaction in modern Python development is often the same: “Just throw async/await at it.” While asyncio is a powerful tool for building high-throughput services, treating it as … Read more

After training hundreds of creators, the same failure point shows up before anyone opens a video model. Every week, in the masterclass I run for AI Studios, someone shares a shot that took an entire evening to build. The lighting is right. The camera move is smooth. The character does not fall apart mid-motion. And … Read more

Why a drone-and-vision guy cares about cows Most of my work sits at the intersection of computer vision, drones, and edge inference: vision-only navigation for GPS-denied flight, detection pipelines, pose estimation for controlling machines with the human body. For a while I treated agriculture as “someone else’s domain.” That changed when I started noticing that … Read more

Photo Courtesy: GoodRec Booking a pickup game used to mean a group chat, a maybe-available field, and hoping enough people actually showed up.

What problem … Read more

I have recently been observing a phenomenon I can only describe as the industrialisation of doing absolutely fuck all. Not ordinary laziness.

This is … Read more
