Don't Replace Your Legacy System. Wrap It.
We're Byte Me , a software agency from Alkmaar, the Netherlands. The most valuable advice we give clients is usually not "Let's build something new"; it's "Let's not touch the thing that works." Here's why and how. The rebuild reflex Every company running a 15-year-old ERP has had this meeting. Someone opens the ancient interface on the big screen, everyone groans, and a decision crystallizes: "We need to replace this." We understand the reflex. The UI looks like Windows XP. The one person who understands the database retired. Adding a field takes a change request and three weeks. Every new hire asks why orders live in a system older than they are. And yet, when companies come to us with "We want to replace our legacy system," our first answer is almost always: you probably don't. Not because rebuilds are impossible but because the odds are terrible. Big-bang legacy replacements are among the highest-risk projects in software. They take longer than planned, cost more than planned, and the scariest part isn't the code: it's the twenty years of business rules buried in that old system that nobody documented. The weird discount logic for that one big customer. The field that means something different depending on which decade the record was created in. The nightly job everyone forgets exists until you turn it off. That old system isn't just software. It's your company's institutional memory, compiled. Ugly ≠ broken Here's the reframe that changes these conversations: most legacy systems don't have a functionality problem. They have an access problem. The ERP still processes orders correctly. It's been doing so, reliably, for fifteen years, a track record your rebuild won't have on day one. What's actually painful: Customers can't see their own orders, so they email and call Sales can't check stock from the road Data has to be retyped into the accounting tool, the webshop, the planning board Reporting means exporting to Excel and praying None of those problems require r

Ask Claude to Publish a Website. Get a Permanent Link.
I gave Claude one prompt. Claude wrote a web page and published it. The page is live at a permanent URL. I did not open a dashboard. I did not run a build. This article shows the full procedure. You can complete it in less than five minutes. Disclosure: I run Nippy , the hosting service in this article. What makes this possible MCP (Model Context Protocol) is an open standard. It lets an AI assistant call external tools. A tool can read data. A tool can also do work in the real world. Nippy is a static hosting service. You give it files. It gives you a live URL that does not expire. Nippy has an MCP server. When you connect it, Claude gets one new ability: it can publish websites. The result is a very short path from an idea to a live page: prompt → Claude writes the files → one tool call → live URL Set up the connector There are two paths. Use the one that matches your setup. Path A: claude.ai in the browser Open claude.ai. Go to Settings → Connectors . Add Nippy as a connector. Approve the connection. Path B: Claude Desktop, Claude Code or Cursor Run the MCP server with one command: npx nippy-mcp Add it to your client configuration. For Claude Desktop, the entry looks like this: { "mcpServers" : { "nippy" : { "command" : "npx" , "args" : [ "nippy-mcp" ] } } } Restart the client. The Nippy tools are now available. The Nippy help center has a full guide for each client. Publish a page Give Claude a prompt. This is the prompt I used: Make a small demo page and publish it with Nippy. Claude then does three things: Claude writes the HTML file. Claude calls the Nippy MCP server with the file. Nippy returns a live URL. The tool call is simple. This is its shape: { "name" : "published-by-claude" , "files" : [ { "path" : "index.html" , "content" : "<!DOCTYPE html>..." } ] } The response came back in a few seconds: { "url" : "https://published-by-claude.nippy.site" , "status" : "live" , "note" : "Live now. The link does not expire." } That page is real. Claude published it

How to Build a Resilient Edge Data Pipeline for Power Line Sensors
Modern electrical grids increasingly rely on distributed sensors installed across conductors, towers, poles, substations, and remote line sections. These devices can measure: Conductor temperature Current and voltage Mechanical tension Line sag Vibration Weather conditions Fault passage Switch and recloser states Collecting these measurements is relatively straightforward. Building a reliable data pipeline around them is much harder. Power infrastructure often operates in locations with unstable connectivity, limited bandwidth, and strict requirements for alarm delivery. A useful architecture must therefore do more than move telemetry from sensors to a cloud database. It must determine which data is urgent, validate measurements, preserve event order, survive network outages, and integrate the results with operational utility systems. This article explores how to design that pipeline. The Basic Architecture A practical grid-monitoring data flow may look like this: Field Sensors | v Protocol Adapters | v Edge Data Model | +----> Local Rules and Fault Detection | +----> Local Time-Series Buffer | +----> Event Queue | v Central IoT or Utility Platform | +----> SCADA +----> GIS +----> OMS +----> Analytics +----> Maintenance Systems The edge gateway sits between field equipment and central applications. Its job is not limited to protocol conversion. It also acts as a local data-processing and reliability layer. Why Cloud-Only Processing Is Risky Imagine a utility operating 5,000 field sensors. Each device reports one measurement every second. That produces: 5,000 measurements per second 300,000 measurements per minute 18,000,000 measurements per hour Most of those measurements will describe normal operating conditions. Sending every individual value to a central platform creates unnecessary: Bandwidth consumption Storage growth Processing overhead Communication costs Dependence on network availability More importantly, cloud-only logic can stop working when the connectio

HLS Streaming Explained: How HTTP Live Streaming Works (Beginner's Guide)
Video streaming has become a normal part of everyday life. Whether you are watching a live sports event, attending an online class, listening to internet radio, or enjoying a movie on a streaming platform, a complex technology system is working behind the scenes to deliver content smoothly. Most viewers simply press Play and start watching. They do not see the technology that makes videos load quickly, reduce buffering, and automatically adjust quality when internet conditions change. One of the most important technologies behind modern streaming is HTTP Live Streaming (HLS) . HLS is a widely used video streaming protocol that delivers high-quality audio and video across different devices and network conditions. Instead of sending one large video file, HLS divides content into smaller pieces called media segments and delivers them continuously while the viewer watches. For example, when a video automatically changes from 1080p to 720p during a slow internet connection without stopping completely, that experience is powered by Adaptive Bitrate Streaming (ABR) , one of the main features of HLS. In this guide, you will learn: What HLS Streaming is How HTTP Live Streaming works Why Apple created the HLS protocol How M3U8 playlists control video delivery How media segments are created How Adaptive Bitrate Streaming improves playback Where HLS is commonly used How HLS compares with other streaming technologies Whether you are a beginner learning about video technology or a developer exploring streaming protocols, this guide explains HLS step by step. What Is HLS Streaming? HTTP Live Streaming (HLS) is a video streaming protocol created by Apple that delivers audio and video content through standard HTTP and HTTPS connections. Unlike traditional video downloads, HLS does not send a complete video file at once. Instead, it breaks the content into many smaller parts called media segments and sends them one by one while the viewer is watching. This approach provides several a

Bifrost AI Gateway Would Have Saved My App
I was showing ChefExtract to some friends when it started returning error 404 for specific operations linked to AI. After some embarrassment, I went home to figure out the problem: The model I used for those specific operations had been deprecated. And just like that, my app was failing. But I learned my lesson: relying entirely on one API creates a single point of failure (not rocket science). The easiest fallback mechanism would be to rely on a backup model. But these increase maintenance, and it doesn’t scale well. A better fix relies on AI gateways. What is an AI gateway? An AI gateway is a middleware layer that sits between your application and the LLM providers. Instead of your code calling OpenAI or Anthropic directly, it calls the gateway, and the gateway forwards the request. Concretely, a gateway buys you four things: One API for many providers. Write your code once, switch between GPT, Claude, Gemini, or a local model without rewriting anything. Automatic failover. If your primary provider fails or deprecates your model (as it happened to me), requests reroute to a backup. Users never see a 404. Cost control and caching. Budgets, rate limits, and cached responses for repeated queries, enforced in one place instead of scattered across your codebase. This is especially useful when relying on models from different providers. Observability. Every request is logged, timed, and priced, so “why is our AI bill so high?” becomes a query instead of an investigation. Once again, this is especially useful when dealing with multiple models from different providers. This is exactly what my app needed. Failover alone would have turned my deprecated-model incident into a non-event. Enter Bifrost There are many AI gateways, but eventually I explored one called Bifrost because it is open source and you can see how it operates under the hood. Bifrost is an open-source AI gateway built by Maxim AI and written in Go. Bifrost bridges your app to more than 20 providers: OpenAI,

React Performance Optimization Techniques That Actually Work
Performance optimization in React is often surrounded by myths. Developers routinely wrap every single component in React.memo , wrap every function in useCallback , and wonder why their application is still sluggish or memory-heavy. Premature optimization can actually degrade app performance and clutter your codebase. To build fast React applications, you need techniques that address actual bottlenecks: unnecessary re-renders, unoptimized state placement, oversized bundles, and main-thread blocking. Here are five practical React performance optimization techniques that deliver measurable results in production. 1. Push State Down (Fix Rerender Cascades) Before reaching for useMemo or React.memo , evaluate your state placement . When state lives too high up in the component tree, every state update forces the entire sub-tree to re-render. ❌ The Anti-Pattern: State at the Root // Changing `color` forces <HeavyChartComponent/> and <ComplexTable/> to re-render! export default function App () { const [ color , setColor ] = useState ( ' #6366f1 ' ); return ( < div > < input type = "color" value = { color } onChange = { ( e ) => setColor ( e . target . value ) } /> < p style = { { color } } > Sample Text </ p > < HeavyChartComponent /> < ComplexTable /> </ div > ); } ✅ The Fix: Component Isolation Move the isolated state and its control into its own dedicated child component: Javascript function ColorPicker () { const [ color , setColor ] = useState ( ' #6366f1 ' ); return ( < div > < input type = "color" value = { color } onChange = { ( e ) => setColor ( e . target . value ) } /> < p style = { { color } } > Sample Text </ p > </ div > ); } export default function App () { return ( < div > < ColorPicker /> { /* These components are no longer impacted by color state changes */ } < HeavyChartComponent /> < ComplexTable /> </ div > ); } 2. Pass Components as Children (Component Composition) Sometimes state must remain in a parent component, but you don't want child components

Procedure for Modifying a SquashFS-Based Live Linux System
A Live Linux system such as SystemRescue generally has the following structure: ISO9660 ├── EFI/, boot/, syslinux/, grub/ ← Bootloader ├── vmlinuz ← Kernel ├── initramfs ← Initial RAM disk └── airootfs.sfs / filesystem.squashfs └── Actual root filesystem Because SquashFS is read-only, the basic process is as follows: Extract the ISO ↓ Extract the SquashFS ↓ Edit the rootfs or enter it with chroot ↓ Rebuild the SquashFS ↓ Replace the SquashFS inside the ISO ↓ Rebuild it as a bootable ISO ↓ Test with BIOS and UEFI However, with SystemRescue, it is safer not to rebuild airootfs.sfs directly from the outset, but to select a method in the following order of priority: YAML configuration in sysrescue.d Overlay using an SRM (SystemRescueModule) Direct reconstruction of airootfs.sfs Full build from the SystemRescue source The official SystemRescue documentation also recommends sysrescue-customize for modifying ISO images. An SRM is an additional layer in SquashFS format, and files at the same paths in the SRM take precedence over those in the base rootfs. ( SystemRescue ) 1. Preparing the Working Environment It is easiest to perform this work on Linux. On Debian/Ubuntu-based systems, install the following: sudo apt update sudo apt install squashfs-tools xorriso rsync file It is also useful to install QEMU for testing: sudo apt install qemu-system-x86 ovmf The official SystemRescue customization script also lists xorriso and squashfs-tools among its main dependencies. It can also be run under WSL. ( SystemRescue ) Create a working directory: mkdir -p ~/work/systemrescue cd ~/work/systemrescue cp /path/to/systemrescue.iso original.iso Ensure that you have at least several times the original ISO size in free space. When rebuilding from within SystemRescue itself, the official documentation notes that the Copy-on-Write area may require approximately three times the ISO size. ( SystemRescue ) Method A: Use the Official SystemRescue sysrescue-customize Tool For SystemRescue, this
