Industry-wide, fewer than 20% of Web3 wallet users return after 7 days. I used to think that was a competitor problem, then I saw it firsthand at a leading non-custodial wallet on TON. Non-custodial wallets are the only product category where users own their exit as completely as they own their assets. If someone decides … Read more

Many specialists won’t like how freely I use the word “disease” here. But by the end, you’ll understand why I chose it. I’ve personally encountered this phenomenon in a severe enough form to shout about it – the way you’d shout about a serious illness that society doesn’t yet recognize or know how to treat.

Font Converters is a free, privacy-first web tool that turns one font into all the formats you actually need, converting losslessly between the 8 major font formats and generating the matching @font-face CSS. It also re-sets whole documents (PDF, DOCX, and more) in any font, including OpenDyslexic for accessibility, and bundles utilities like a font … Read more

A safe RAG architecture keeps untrusted content out of the prompt where it can do damage, enforces who can read what at the retriever, and limits what the model can do after retrieval. Most RAG systems I have seen in real projects do the first half and skip the rest. They retrieve, they answer, they … Read more

Subtitle: A fraud model is only useful if it improves the way a risk team acts on real transactions. Fraud detection is often described as a machine learning problem. In practice, it is a decision systems problem. That difference matters. You can build a model with a strong offline score and still end up with … Read more

On one of our projects, we were building microfrontends, and at some point we wanted to add SSR. The reasons were the usual ones: better first paint, fewer layout shifts, real content for crawlers, less JS to load before something appears on screen. Setting it up turned out to be harder than I expected. There … Read more

Flipsnack’s AI Living Visuals turns static images into cinematic motion directly inside digital documents — no video production workflow required. Since launching in March 2026, the feature has averaged 60 AI-powered generations per day across 3,000+ users, driven by one core insight: enterprise teams have always known motion content performs better, they just never had … Read more

The agentic era created a new infrastructure need: a control layer for deciding which AI-driven, automated, or human-triggered actions are allowed to proceed. Devenex is giving a name to a problem many enterprises were already beginning to feel. Every major shift in enterprise technology eventually creates a new control category. Systems of record emerged because … Read more

From deduplication to frequency analysis, learn how to turn raw terminal output into actionable insight. Raw output lies to you. A list of 3,000 IP addresses means nothing until you know which ones appear 500 times and which ones appear once. A credential dump is useless until you know which passwords are shared across accounts. … Read more

Late 2025 through early 2026 was one of the most intense periods of my career. I was deep in the trenches, designing and deploying AI agents for real enterprise clients in fintech, healthcare payments, and compliance. Out of 47 agents we pushed into production, only 6 are still delivering consistent value today. The difference wasn’t … Read more

APIs are now the default interface for modern applications. They expose business logic, identity flows, mobile backends, partner integrations and internal services. That also means API testing often requires more than a generic web scan. Burp Suite is excellent for manual analysis, but API security testing benefits from repeatable automation: checking JWT behavior, validating object-level … Read more

We can’t really know how many games out there exist, but they’re in the millions. Not all of them are exclusive or paid, by the way, and we can use some open tools to access them. Indeed, many of the apps you might use as a gamer, from emulators to streaming programs, come from the … Read more

Every open blockchain is, structurally, a surveillance machine for your counterparty. Fhenix’s FHE infrastructure and Monaco’s institutional-grade trading layer are attempting something most thought impossible: private execution that doesn’t break the trust model of DeFi. There is a problem in DeFi that nobody has properly fixed, and the reason it hasn’t been fixed is that … Read more

My agent leaked a customer’s email address to another customer on day three. This was not a hypothetical scenario from a conference talk. It was my code, running in production, doing something I never tested for.

Real-time usage metering makes the customer’s balance the source of truth, settling every usage event against it as it happens instead of at month end. Only 43% of organizations can attribute AI cost to a single customer (CloudZero, May 2025), and the lag between usage and billing is where that visibility disappears. For workloads with … Read more

It was an afternoon when one of our reconciliation flows started throwing NullPointerExceptions in production. The fix, once we found it, was two lines. Finding those two lines took nearly six hours. Three engineers and endless log grepping. Tracing through an integration application with JSF UI that predates most of the libraries we take for … Read more

When I was building my own serverless runtime, the first major decision I had to make was: how will the host and the VM communicate? It looks simple on the surface, but every choice has a tradeoff. My invocation flow looks something like this — a request arrives at the control plane, it gets sent … Read more

If your tickets take two weeks to cross the board while coding takes a few hours, the problem isn’t effort — it’s how much work your team keeps in flight at the same time. And there’s a 65-year-old law that explains exactly why.

Behind every AI kilowatt-hour is a hidden river of evaporated water. Training a model like GPT-3 consumed 636,000 gallons—enough to fill an Olympic pool—while daily inference “drinks” a bathtub per user every week. This post reveals that data centers are massive water evaporators, with AI-driven cooling demands sometimes exceeding energy impacts. We compare water usage … Read more

Anthropic’s new frontier model, Mythos, signals a dangerous shift toward “AI enclosure”—gating the most powerful cognitive tools behind seven-figure enterprise and government contracts rather than technical merit. Because its “safety” and performance claims are backed by PR rather than reproducible public benchmarks, it amplifies inequality and forces developer dependency on opaque, closed ecosystems. The solution … Read more
