Google Adds Event-Driven Webhooks to the Gemini API, Eliminating the Need for Polling in Long-Running AI Jobs

⋅

If you’ve ever built a production AI pipeline that runs long jobs — processing thousands of prompts overnight, kicking off a Deep Research agent, or generating a long video — you’ve almost certainly dealt with the polling problem. Your code sits in a loop, firing GET requests every few seconds asking, “Is the job done yet?” It’s wasteful, it adds latency, and at scale it becomes a reliability headache. Google just shipped the fix. Google introduced event-driven Webhooks […]

Build a Modular Skill-Based Agent System for LLMs with Dynamic Tool Routing in Python

⋅

In this tutorial, we build a complete skill-based agent system for large language models and explore how modular capabilities can be structured like an operating system for AI agents. We define reusable skills, attach metadata and schemas to them, register them in a central registry, and enable dynamic orchestration through tool calling and multi-step reasoning. As we move through the implementation, we show how an agent can select the right skill for a task, compose multiple skills for […]

NPG: New Random Generator, 3x Faster & Stronger than PCG64

⋅

The NumPy library in Python, and many other systems, relied on the Mersenne Twister PRNG (pseudo-random number generator) for a long time. It was slow and did not mimic randomness well enough, failing some statistical tests. In addition, it could be cracked, raising security issues. It was replaced recently by PCG64 which addresses some of these issues. Nowadays, PCG64 is widely adopted. In the meanwhile, for over 2 decades, I worked on this topic. My efforts culminated when […]

Changing one character in a PDF

⋅

I saw a post on X saying Changing a hyphen to an en-dash increases your PDF file size by ~10 bytes. My first thought was that it had something to do with hyphen being an ASCII character and an en-dash not. Changing a hyphen to an en-dash would make a UTF-8 encoded text file a couple bytes longer. (See why here.) Maybe adding one non-ASCII character could cause the file to include a glyph it didn’t before. I […]

When Accuracy Lies: Rethinking Metrics in Imbalanced Multiclass Models

When Accuracy Lies: Rethinking Metrics in Imbalanced Multiclass Models

⋅

Accuracy doesn’t lie — but it doesn’t tell the whole truth either. 1. Introduction In the world of AI, building Machine Learning (ML) models has become surprisingly easy, sprinkle in a bit of creativity, test a few architectures, and chances are you’ll get some fascinating results. The size and the architecture of these models often depend on how complex the underlying data distribution is. But in this excitement, we often tend to overlook something fundamental: The role of model evaluation metrics. […]

Our AI started a cafe in Stockholm

⋅

Our AI started a cafe in Stockholm Andon Labs previously started an AI-run retail store in San Francisco. Now they’re running a similar experiment in Stockholm, Sweden, only this time it’s a cafe. These experiments are interesting, and often throw out amusing anecdotes: During the first week of inventory, Mona ordered 120 eggs even though the café has no stove. When the staff told her they couldn’t cook them, she suggested using the high-speed oven, until they pointed […]

Warps, Memory Hierarchy, and Why Bandwidth Beats FLOPS : How GPUs Actually Work, Part 1

Warps, Memory Hierarchy, and Why Bandwidth Beats FLOPS : How GPUs Actually Work, Part 1

⋅

A working mental model of GPU hardware for ML engineers who use these chips daily but have never traced what happens below the CUDA API Generating a single token from a 70 billion parameter model on an H100 requires reading roughly 140 GB of weights from memory and performing about 140 billion arithmetic operations on them. That works out to one operation per byte loaded. Memory bandwidth, not compute throughput, determines how fast that token comes out. By the […]

Closing the ‘Expressivity Gap’: How Mistral’s Voxtral TTS is Redefining Multilingual Voice Cloning with a Hybrid Autoregressive and Flow-Matching Architecture

Closing the ‘Expressivity Gap’: How Mistral’s Voxtral TTS is Redefining Multilingual Voice Cloning with a Hybrid Autoregressive and Flow-Matching Architecture

⋅

Voice AI has a dirty secret. Most text-to-speech systems sound fine — until they don’t. They can read a sentence. What they cannot do is mean it. The rhythm is off. The emotion is flat. The speaker sounds like themselves for two seconds, then drifts into generic synthetic territory. That gap between intelligible audio and truly expressive, speaker-faithful speech is what we call the ‘Expressivity Gap’ — and it has been the defining bottleneck for every developer trying […]

Widely used Daemon Tools disk app backdoored in monthlong supply-chain attack

Widely used Daemon Tools disk app backdoored in monthlong supply-chain attack

⋅

Daemon Tools, a widely used app for mounting disk images, has been backdoored in a monthlong compromise that has pushed malicious updates from the servers of its developer, researchers said Tuesday. Kaspersky, the security firm reporting the supply-chain attack, said it began on April 8 and remained active as of the time its post went live. Installers that are signed by the developer’s official digital certificate and downloaded from its website infect Daemon Tools executables, causing the malware […]

RFK Jr. plans to curb antidepressants, which he falsely compares to heroin

RFK Jr. plans to curb antidepressants, which he falsely compares to heroin

⋅

In a brief appearance at a Make America Healthy Again Institute event Monday, anti-vaccine Health Secretary Robert F. Kennedy Jr. announced new federal initiatives to curb prescribing of antidepressants, which he has long attacked with false and dangerous claims. Mental health experts have previously condemned his rhetoric and are already pushing back on his new efforts. The MAHA event was focused on “overmedicalization,” with participants broadly alleging—without evidence—that too many Americans, particularly youths, are overprescribed antidepressants in the […]
