Most developer machines are not clean. They just look clean. At some point, every dev laptop turns into a dumping ground. You install tools to follow a blog post. You try a framework for a weekend. You switch jobs and inherit a new stack. You uninstall things, but only halfway. Binaries stick around. Config files … Read more

Turn a photo and voice into a convincing talking avatar—then add a second character for dialogue. Here’s what longcat-multi-avatar does best, plus experiments to try.

Guess what? There are some useful and fun software programs around for pet owners, too. We can even use some projects for free. The open-source world is full of clever, heartfelt projects that help shelters, protect lost animals, or make it easier to manage your pet’s day-to-day life. Many of these tools run on passion … Read more

The crypto industry is now worth trillions, but Rome wasn’t built in a day. Over the years, many developers, enthusiasts, and users of all kinds and places have put their own blocks to raise this bright skyscraper. We’ve crossed some huge milestones, sometimes through careful planning, sometimes through happy accidents, and often through bold experiments. … Read more

A practical LTX-2 guide: inputs/outputs, text-to-video and image-to-video, the 19B and 8-step variants, BF16 training, LoRA tips, and how to get cleaner results with proper dimensions.

Check Point’s Cyber Security Report 2026 shows 70% increase in cyber attacks since 2023. 60% of executives reported their organizations faced AI-powered attacks, but only 7% had deployed AI defenses at scale. Moody’s 2026 cyber outlook warns that AI-related threats will “become more prevalent and pronounced”

Introduction: The Hypermedia Renaissance We are living in the middle of a hypermedia renaissance. Frameworks like HTMX have correctly identified that the “Single Page Application” (SPA) model often introduces unnecessary complexity, pushing developers to manage state in two places and build expensive APIs for what should be simple UI updates. The core premise of HTMX … Read more

There is a difference between employability and employed. The solution mostly offered is reskilling, upskilling or further education. Project management is no longer a way to marshal tech employees.

A revenue dashboard drops 18% overnight. The pipeline is ‘green.’ The lineage graph looks right. Query history shows the job ran successfully. Yet you still can’t answer the only question leadership cares about: what changed—and can we prove it? Traditional lineage is built for discovery: it shows what depends on what. Incidents demand evidence: what … Read more

The World Health Organization (WHO) says that employee burnout is an “occupational phenomenon”. It goes beyond being tired, having time off, or missing a deadline; it’s a state of ongoing mental and physical exhaustion caused by a range of workplace factors. Employees who are experiencing burnout often feel exhausted, disconnected from their work, struggle to … Read more

We are moving past the era of simply “chatting” with AI code editors. The difference between a junior developer using AI and a senior architect using AI is context orchestration. If you treat Cursor like a chatbot, you get generic code. If you treat it like a specialized agent operating within rigid architectural boundaries, you get … Read more

Over the last year, I keep hearing the same statements in meetings, reviews, and architecture forums: “We’re doing AI.” “We have a chatbot now.” “We’ve deployed an agent.” When I look a little closer, what most organizations really have is not enterprise AI. They have a tool. Usually it is a chatbot, or a search … Read more

The fastest way to get burned by AI coding tools is to treat them like a vending machine: “prompt in, perfect code out.” They’re not. They’re closer to an eager junior engineer with infinite confidence and a fuzzy memory of docs. The output can look clean, compile, and still be wrong in ways that only … Read more

Abstract— Processing payroll data in response to events such as timesheet file uploads, benefits enrollment changes, and employee status updates represents a critical workflow in modern Human Resources systems. Traditional implementations deploy custom applications on on-premises infrastructure, requiring dedicated servers, file shares, and continuous monitoring services. This approach incurs substantial costs for server hardware, software … Read more

People often ask why institutions fail. They blame bad leaders, eroded morals or hidden agendas. I think that is usually wrong. Systems collapse not primarily because people are evil, but because power is permitted to operate without clear, enforceable limits. To see this clearly, let’s get 2 unlikely mentors: Roman Republic (not the empire) ( … Read more

Jake Harlan spent two years hauling ice and rare metals between the Jovian trojans and the inner markets. He had not pinged ahead. Wanted to surprise Lena. Two years was a long stretch, even for freight dogs.

Let me tell you a story There is a tidy, almost academic version of how software security is supposed to work. It appears in conference talks, compliance documents and in the cheerful diagrams seen on marketing slides. It usually looks something like this: A researcher finds a bug, quietly (and professionally) reports it upstream, upstream … Read more

After building a crypto social app to 500K users, serial entrepreneur Nilesh Rathore brings the same “make it feel simple” philosophy to health and fitness with KAAYA, now live on iOS and Android. Most AI fitness apps are essentially chatbots grafted onto traditional calorie counting. KAAYA (https://kaaya.app), launching today with over 5,000 early users, takes … Read more

The crypto market is entering a phase where performance is no longer moving in one direction. Large, well-known assets are showing slower momentum, while smaller utility-driven protocols are starting to separate themselves. In early 2026, this shift is becoming easier to spot. Growth is no longer limited to the names dominating headlines. Within decentralized finance, … Read more

In the communications industry, the press release has always been a fundamental tactic in the asset tool chest. You wrote it once, distributed it once, and hoped it did three things at the same time: inform journalists, signal credibility, and, at least in the last decade+ help with search. This no longer holds. Today, announcements … Read more

In this post I explore new paradigms brought by agentic development tools, lessons learned from building systems with AI tooling, and what that could mean for the software engineering practice (not “just coding”) within the next few years. “AI is making developers 10x” [link], “AI is making developers less productive” [link], “AI is coming for … Read more

A survey of 200 active Laravel developers shows strong reliance on third-party packages, but growing frustration with poor documentation, abandoned tools, and the lack of standardized ways to evaluate package health—prompting the need for better curation.

Writing in public for one month showed that consistency is manageable, but distribution and authentic engagement—not writing—are the real long-term challenges.
