Are there any guides for converting a single-package repo into a two package monorepo?

I've got a repo that is currently a CSS library and a javascript library in one package, and it's kind of getting a bit clumsy. You'd figure this would be a simple thing to do, but all the resources I'm finding are along the lines of "here's how you can take your 10-repo project and make a mono repo" or "here's how you can still use this tool and have a single-package repo". I don't think I need anything incredibly sophisticated. Maybe I'll have more than two packages at some point, maybe not. Does anyone know of any guides for this? Do you have any advice for tools I can use? I know pnpm has support for monorepos, but it's not really well-documented. Would that be sufficient, or would I need a tool like nx or the thousand other monorepo tools that are out there? submitted by /u/CoVegGirl [link] [留言]

Loading custom themes, standard/recommend method?

When loading custom themes made by the user & stored somewhere for example local storage, I assume the flow is: 1-Read theme data from storage 2-Flatten theme & generate CSS text 3-Dynamically inject it as a style to the document, os use cssom to add sheets 4-Use [data-theme="custom1...n"] to switch themes Or Have a single placeholder [data-theme="slot"]{} In your static CSS, just read the user selected theme only, flatten, loop over variables & use cssom set property to set the values of tge slot style to those of the theme, & use data-tgeme=slot to activate it, & when the user selects another custom theme load it the same way using cssom & so on & so on, basically injecting a style css vs cssom adoptsheet (which I think has/had? A bug in FF), & load all/many (maybe lazy load), or swap in & out in a static pre-defined css style slot? submitted by /u/Ok-Weakness-3206 [link] [留言]

The problem with security scanners isn't the scanning

At a previous job I worked at as a Dev we had someone who ran Semgrep on our codebase for the first time. It came back with 180 findings. We had no security engineer. The developer who ran it looked at the output, closed the terminal, and we never ran it again. That's not a story about a careless team. That's a story about a tool that produced output most teams in small companies with no expertise knew what to do with. I've seen this exact moment happen more times than I can count working with small dev teams. And it's the reason I spent the last year building SecOpsium. But before I get to that let me explain the actual problem, because I think it's misunderstood. The problem isn't the scanning Semgrep and Gitleaks are excellent tools. They're free, actively maintained, and genuinely powerful. If you're not using them you should be. The problem is what happens 10 minutes after you run them. You get 200 findings. Some are critical. Some are test files. Some are commented-out code from 2021. Some are legitimate secrets. Some are variable names that pattern match against a rule but contain nothing sensitive. They all look the same in the output. Now you're a developer who also does DevOps, also reviews PRs, also handles incidents, and you're staring at 200 items with no clear indication of which three actually matter this week. So you close the terminal. Or you create a Jira ticket labeled "security findings" that lives in the backlog forever. Or you spend two days triaging manually and burn out before you fix anything. This is the real problem. The scanning was never the hard part. Why rule based scanners produce so much noise It helps to understand technically why this happens. Semgrep and Gitleaks are rule-based. They match patterns. A variable named api_key_example in a test file flags the same way as a live Stripe key in an active production config. Gitleaks scans for entropy and known credential patterns but can't distinguish between a key that was rotated and r

Blaming the model won't fix your workflow — a white paper on structural enforcement for AI agents

I've been working on something others might find interesting. It's under heavy development as I learn. Most AI agent setups treat the model like a better autocomplete — paste a prompt, get output, hope it's right. That works for small tasks. It falls apart when you try to use agents for sustained work across sessions: they skim specs, declare victory at 60%, burn context on noise, silently resolve ambiguity without surfacing it, and mark checklist items done without actually doing them. The failures are predictable and nameable — so I named them. This is a white paper and implementation guide for a full-stack agentic system — everything from planning through promotion under structural enforcement. It documents 24 failure modes from months of multi-agent operation and, for each, describes what actually prevents it: some through mechanical gates the agent cannot skip, some through procedural skills, and some through human supervision. The guide covers how to structure specs, plans, and verification so that agent work is evidence-led rather than vibes-led, how to use MCP capability surfaces as structural levers, and how the failure modes apply regardless of which model or vendor you use. The white paper also includes a Related Work section that positions it against the emerging industry consensus — CodeRabbit, Anthropic, Spotify, Cloudflare, OpenAI, Karpathy, Thoughtworks, and academic research all independently arrived at pieces of the same conclusions. The difference here is the integrated stack: a failure taxonomy mapped to prevention mechanisms, a three-layer enforcement architecture, and a concrete reference implementation with an orchestrator, task graphs, step verification, adversarial review, and model stratification.

Put your Coding Agents in Drive w/ Superpowers (aka How Superpowers is the Automatic Transmission of Agentic Coding)

The most downloaded and widely used methodology in the Claude Code ecosystem is Superpowers , with over 208k stars⭐️ and 18.5k forks🍴 on GitHub (and counting!) Going from raw Claude Code to using Superpowers is as revolutionary as going from a manual transmission to an automatic. Here's why this analogy holds: Planning Mode vs. Coding Mode When we build with Claude (or Codex, or Gemini...), we're usually in one of two states: planning mode coding mode Like shifting gears in a car🚘, moving between these modes effectively is what makes it all work. Skip the shift, and you're just revving your engine (aka burning context and going nowhere.) Superpowers lets Claude automatically detect and shift between these modes. It picks up on ambiguity in your prompt and ensures it fully understands the task before entering coding mode. No manual shifting required! Slower, but for Good Reason Superpowers can feel slower and less satisfying than raw Claude Code, like how driving an automatic can feel less engaging than a manual. But both serve the same critical purpose: they stop you from blowing up your engine! That said, there's still a time and place for raw Claude. Sometimes you want direct, fast, unmediated output. But that minor gain in speed often isn't worth the added complexity, the ambiguity risk, and the tradeoffs that come with it. The Layer Underneath Entire is building the foundation beneath all of this — capturing every session and decision, and linking it to the commit it produced. It's the full record of how the code was written, not just the code itself. So the question is this: how will you put your agent in drive🚘?

Why I built tmpdrop: a self-hosted, expiring file drop

I had a screenshot to send. Nothing secret — a stack trace from a side project — but it had an internal hostname, a file path with my username, and a chunk of a config file in the terminal behind it. The fast move is to drag it onto a free image host and paste the link. I sat there with my cursor over the upload button and couldn't do it. Because I know what happens next. That image lives on someone else's infrastructure, indefinitely, behind a URL I don't control, and I have no idea who else can reach it. For a throwaway screenshot, that's a permanent record I never agreed to. So I closed the tab and built a thing instead. It's called tmpdrop , and it's ~500 lines of Node. The threat model The problem with public file hosts isn't that they're evil. It's the gap between what you intend ("share this once, with one person") and what the platform delivers ("store this forever, serve it to anyone who finds the link"). A few specific things go wrong: Retention. "Temporary" hosts keep your files long after you've forgotten them. There's no expiry you can trust, and deletion is usually best-effort. Predictable URLs. Plenty of hosts use sequential or short IDs. Scrapers walk the keyspace and hoover up everything. Your "private" link was never private. Stored XSS via uploads. If a host serves an uploaded .html or .svg file inline with a permissive content type, an attacker can ship JavaScript that runs in your browser, in the host's origin. Your file host becomes an XSS delivery service. Abuse vectors. No rate limit means the box is a free CDN for whatever someone wants to dump on it — malware, spam payloads, the works. So the design goal wasn't "another uploader." It was: close each of those gaps, then stop. What I built tmpdrop is a single Fastify server backed by SQLite. The whole defensive surface is small enough to hold in your head: Unguessable URLs. Slugs are 9 random bytes, base64url-encoded — 72 bits of entropy. You cannot enumerate them. A TTL reaper. Every upload

Discovering Google Lighthouse . A Small Tool That Changed How I See Web Development

Today I discovered something I honestly should have explored a long time ago: Google Lighthouse. Funny enough, revamping my portfolio is one of those projects I kept pushing forward with the classic “I’ll do it tomorrow” mindset — and somehow tomorrow kept winning. But today I finally sat down and started improving it, and during that process, I came across Lighthouse. For anyone who hasn’t heard of it yet, Google Lighthouse is an open-source automated tool designed to help developers improve the quality of web pages. You can run it on almost any page — whether it’s public or behind authentication. What immediately caught my attention is that it audits things like: Performance Accessibility SEO Best Practices And probably a few more things I’m still discovering You can run Lighthouse directly inside Chrome DevTools, through the command line, or even as a Node.js module. The process is simple: You give Lighthouse a URL, it scans the page, runs a series of audits, and then generates a detailed report showing how your website performs. What makes it powerful is that it doesn’t just tell you what’s wrong it also explains: _ Why the issue matters How it affects users And how you can fix it _ As a beginner software engineer and developer, I’m slowly realizing that writing code is only one part of building great applications. Performance, accessibility, maintainability, and user experience matter just as much. And honestly, tools like Lighthouse make the learning process feel less overwhelming because they point you in the right direction. One thing I’ll say though don’t fall into the trap of chasing a perfect Lighthouse score instead of building useful projects. A lot of developers start optimizing numbers before validating whether the product itself solves a real problem. Lighthouse is a guide, not the final goal. For my portfolio specifically, Lighthouse exposed a few weaknesses immediately: Large unoptimized images Accessibility issues Slow-loading assets Missing metad
