Tiny JS Libraries Under 2KB: Build Lightweight Web Apps

-
Imagine building powerful web apps without bloating your bundle—here’s how to do it with libraries under 2KB. It’s kind of like packing a full toolbox into a keychain: small, but surprisingly capable. You don’t need megabytes of code to get things done. In fact, the lighter you go, the faster your app feels—especially on slow networks or old phones. And that’s where tools like js come in. It’s an async, non-blocking, event-driven JavaScript runtime built on Chrome’s V8 engine. Think of it like a super-efficient waiter who never waits around—handles one request, moves to the next, never gets stuck. You can run JavaScript outside the browser, on servers or even tiny devices, with almost zero overhead. It’s not magic, but it’s pretty close when you see how much you can do with so little. But here’s the twist: you can even use lightweight patterns from js to inspire how you structure frontend code—yes, even in React Native apps. You’re not replacing React Native, but borrowing its smar...

Master System Design with Python: From Basics to Interview S

-
Whether you're prepping for FAANG interviews or building scalable apps, this guide turns Python into your system design superpower. It cuts through the noise. You don’t need a PhD to get it. Just curiosity and a willingness to learn. And, system design is a broad topic — like trying to map the whole ocean. There are tons of resources out there, but they’re scattered all over the web. Some are too academic. Others skip the basics. It’s kind of like learning to drive by reading car manuals in five different languages. But here’s the good news: we’ll break it down using Python as our tool. Think of it like using LEGO blocks to build a bridge — simple pieces, strong results. You’ll see how ideas like caching, load balancing, and databases click when you code them. So grab your notebook. Let’s get practical. Foundations of System Design We’re talking about the foundations of system design—what makes a system work well when it gets big. Think of it like building with LEGO: if you...

RustDesk: Open-Source Remote Desktop Alternative to TeamView

-
Image
Here is everything you need to know about RustDesk: an open-source remote desktop app designed for self-hosting, as an alternative to TeamViewer. It lets you control your computer from anywhere, with your own server. No third-party cloud needed. You keep your data under your own roof. The app is built with Rust, which means it's fast and secure. You can run it in Docker for easy setup. The project supports multiple languages—Ukrainian, Czech, Chinese, Hungarian, Spanish, Persian, French, German, Polish, Indonesian, Finnish, Malayalam, Japanese, Dutch, Italian, Russian, Brazilian Portuguese, Esperanto, Korean, and Arabic. The developers clearly state they don't support misuse. Unauthorized access or privacy invasion is against their rules. They want the tool used responsibly. And they make that clear upfront. So, if you're looking for a self-hosted remote desktop solution that's transparent and community-driven, RustDesk is worth checking out. It's not per...

How freeCodeCamp’s Open Source Curriculum Is Changing Education

-
Image
The Power of Open Source in Education There’s something different about learning on an open source platform. When the code is public, people can actually see how things work instead of treating the platform like a black box. That transparency builds trust. Nothing is hidden, and anyone can inspect the code, run it locally, or suggest improvements. That’s a big reason why open source communities tend to feel more alive than traditional learning platforms. People aren’t just consuming lessons — they’re part of the process. A learner can notice a bug, fix it, and submit a contribution that helps thousands of others. Someone else might improve accessibility features because they personally struggled with the experience. Over time, those small improvements add up to something much bigger. We’ve seen this happen constantly with freeCodeCamp. Beginners often start by asking questions or fixing tiny issues in the documentation. Then, little by little, they gain confidence and start c...

Mastering JSON in C++ with nlohmann/json – Practical Guide

-
Image
If you've ever struggled to parse or generate JSON in C++, nlohmann/json will change the way you code forever. I used to dread JSON in C++—it felt like fighting the language just to read a config file. Then I found this library, and it felt like someone handed me a wrench that actually fit the bolt. It treats JSON like a first-class data type, so you can create objects with curly braces almost like JavaScript. You can read from a file, build from literals, or even convert straight from STL containers like vectors and maps. And it does all this without making you jump through hoops—no weird macros, no code generation, just include one header and go. It’s not perfect—sometimes the error messages are a bit vague, and yeah, it pulls in a lot of template magic under the hood—but honestly? It just works. And for most of us, that’s more than enough. Give it a try. You might wonder how you ever lived without it. Why nlohmann/json Is the Go-To Library for C++ JSON nlohmann/json ...

Princeton Ends 133-Year Honor Code Tradition Amid AI Cheatin

-
Image
For over a century, Princeton trusted its students to police themselves — until AI made that trust too risky to keep. The university’s honor code, a cornerstone of campus life since 1893, allowed undergraduates to take exams unsupervised, relying on a shared commitment to integrity. But as generative AI tools became more sophisticated and accessible, faculty began observing patterns that suggested a quiet erosion of that trust — not through blatant cheating, but through subtle, hard-to-detect uses of technology during in-person assessments. On Monday, Princeton faculty voted to end the era of unproctored exams, mandating instructor presence for all in-person assessments starting this summer. Under the new policy, professors will serve as silent witnesses — observing without intervening — and will refer any suspected violations to the student-run honor committee for adjudication. The shift isn’t about punishment; it’s about preserving the integrity of a system that has long defi...

Lake Tahoe Residents in the Dark as Data Centers Drain Power

-
Image
While data centers hum with energy, nearly 50,000 Lake Tahoe residents sit in the dark — sacrificed for the digital economy. Lake Tahoe doesn’t know where its power will come from after next ski season—and it’s a major problem for the 49,000 residents who call the region home. The Sierra Nevada tourist hub—home to ski resorts, lakeside casinos, and roughly 25 to 28 million annual visitors—is facing an energy crisis with a familiar culprit: the data centers powering the AI boom. As demand for computing power surges, the region’s already strained grid is being pulled in two directions: serving the needs of tourists and tech infrastructure, while leaving local communities vulnerable to blackouts and rising costs. The Hidden Cost of Digital Growth Digital expansion demands ever-growing computational power, and this surge is increasingly straining local energy grids. Data centers, 5G networks, and cloud services now consume a significant and rising share of electricity in many re...
