Some still carry memories of early big data struggles – those years filled with fragile workflows and unpredictable crashes. Not long ago, running a basic filter on sales records often spiraled into tangled operations. A short script? It quickly grew, burdened by custom retry systems and intricate dependencies. Workers juggled failing tasks while wrestling with … Read more

A new wave of optimism is surrounding Mutuum Finance (MUTM) after the project successfully launched its V1 lending and borrowing protocol on the Sepolia testnet and surpassed $20 million raised in its presale. The DeFi startup has been gaining momentum over recent weeks, with investors and analysts highlighting it as one of the most credible … Read more

We’ve become too used to the myth of the lone genius. The college dropout working in his father’s garage, whose genius idea changes everything. While the myth of the lone genius has always been comforting because it’s dramatic, simple, and glorifies the selfdom belief that world-changing innovation only happens through isolated brilliance. However, the origin … Read more

It costs millions of dollars and months of computing time to train a large language model from the ground up. You most likely never need to do it. Fine-tuning lets you adapt pre-trained language models to your needs in hours or days, not months, with a fraction of the resources. This tutorial takes you from … Read more

Byline: Malana VanTyler Artificial intelligence is a double-edged sword for global enterprises. On the one hand, it optimizes efficiency. On the other hand, it multiplies security risks, such as data leakage via large language models (LLMs). Chetan Pathade, a GenAI Security Engineer, has taken on this challenge. With a rare mix of practical skill and … Read more

Supabase is great. I love Supabase. But the moment I saw “Backups” sitting behind a paid plan, my brain did what every broke founder’s brain does: “I can build that.” And yes, you can. On the free plan. With real automation. Without a server. Without waking up at 2 am to remember “oh yeah, I … Read more

When Windows stops working properly after an update, a driver install, or a software tweak, one of the best ways to get back to a working system is a restore point. Restore points are snapshots of Windows system files, drivers, and registry settings. They don’t touch your personal files, but they let you rewind your … Read more

Abstract Encryption has long been the cornerstone of digital privacy. From TLS securing web traffic to end-to-end encryption protecting messages, modern systems rely heavily on cryptography to prevent unauthorized access. However, encryption primarily protects data in transit and at rest – not the existence, lifetime, or reuse of data itself. In practice, encrypted systems still … Read more

LangGraph, CrewAI, AutoGen, Pydantic AI, and 8 more. What works, what doesn’t, and when to use each.

Learn how to solve memory limits and “context rot” in long-running AI agents using LangChain’s summarization middleware to keep workflows sharp, accurate, and cost-efficient.

Every time you ask ChatGPT a question, you’re making a choice that affects the planet. It’s a choice most of us don’t even realize we’re making.

I used to think that when AI initiatives stalled, it was because the models weren’t good enough. Over time, what I’ve learned is that this is rarely the case. More often, AI exposes something else entirely: programs that were never designed to support systems that learn. In many organizations, AI is treated as the most … Read more

Our world is clinging to an aging financial ghost. For decades, modern money has drifted away from being an equivalent of tangible goods, becoming instead a bureaucratic tool for managing debt and inflation. While gold proved too heavy for the digital age and cryptocurrency largely dissolved into a sea of speculative “emptiness,” a new hard … Read more

“Is coding essential for UX Designers?” If I had a nickel for every time a mentee or someone asked me this very question, I’d probably have enough to buy a lifetime subscription to Figma. As a UX Designer who’s heavily dependent on research, I remember doing my due diligence and extensively scouring the internet, as … Read more

We live in a world obsessed with speed. Faster apps, quicker deliveries, instant updates, and endless streams of information define our daily lives. In this race to move faster, topics that require patience and long-term thinking—like the environment—often feel slow, inconvenient, or easy to ignore. Yet, the environmental challenges we face today are deeply connected … Read more

For many businesses, data science drives strategic decisions; as a result, most initiatives to improve analytics lack measurable impact. Dashboards are created, models are deployed, forecasts produced but leadership still poses an old question: Did this move the needle? However, tackling this question, beyond predicting, toward measurement of causally based on data and insights, is … Read more

A simplified guide to fal-ai’s ltx-2-19b/distilled/extend-video—generate synchronized audio for existing video with lower compute and production-friendly speed.

Understand when to use ltx2-v2v-trainer vs text-to-video LTX-2 checkpoints, and what you can build with fine-tuned video-conditioned models.

Learn how Nunchaku’s quantized Qwen Image-Edit-2509 delivers rapid image edits—plus how to choose INT4 vs NVFP4, lightning steps, and rank settings.

This article explains how Volume Shadow Copy and the Volume Shadow Copy Service work in Windows 11, covering snapshot behavior, copy-on-write storage, dependent services, and key administrative commands for managing system recovery.

Building AI features is straightforward until you need to integrate them into a production system. In production, a simple ‘call an LLM’ often becomes: wiring HTTP/JMS/Kafka/file inputs, enforcing timeouts, retries, fallbacks, stitching context obtained from internal data sources, protecting secrets, making it testable without burning API credits, and ensuring the system is observable when issues … Read more

This article explores a conservative looping strategy on Fluid using USDe/USDT on Arbitrum. With ~8.9% APY and a liquidation buffer of ~12%, the strategy prioritizes liquidity and risk-adjusted returns over maximum yield. Break-even is reached after ~6–8 weeks. Assets Use reliable stablecoins from trusted issuers, where the probability of a depeg is very low. The … Read more

A book first published in 1962—Thomas Kuhn’s The Structure of Scientific Revolutions—isn’t where you’d expect to find guidance for shipping production AI. But Kuhn’s core point about paradigms clicked instantly for me: reliability starts when you make your “world” explicit—what exists, what’s allowed, what counts as evidence—and then enforce it. That’s exactly what I needed … Read more

High-scale systems fail in many unexpected ways that you would never have designed for. Over the course of the last 14 years, I have navigated the layers of physical and virtual networking. I started out as an individual contributor writing code for data plane services and transitioned to leading global teams managing highly distributed services … Read more

I discovered nport (https://github.com/tuanngocptn/nport) – a fantastic ngrok alternative built in Node.js. It’s free, open-source, and uses Cloudflare’s infrastructure. But I wanted something with: Smaller footprint – Single binary, no Node.js runtime Faster startup – Go’s compilation speed Better concurrency – Native goroutines Learning opportunity – Deep dive into tunneling tech So, I decided to … Read more

The “House of G.E.T.S.” Technical Deep-Dive In today’s article, we’ll take a look at the first “Wall” most offensive security students hit: The Null-Terminator Constraint. I don’t blame the students for hitting it; it’s the first wall that many instructors also gloss over. I’m not just talking about the standard “identification of bad characters”—though they … Read more

Software Engineer, Joachim, shares his first 5 years in review. Joachim shares his top tips on how to succeed as a software engineer.

Software engineers tend to judge older code without understanding its context. Code is only the visible part of the story, but not the context in which decisions were made. Deadlines, team size, available tools, business pressure, and technical limitations rarely survive in repository.
