The Logitech G512 X 98 lets you swap between mechanical and analog switches in an attempt to achieve the best of both worlds. Unfortunately, its solution isn't as well thought-out as I'd hoped.

Hello Dev.to Hello everyone, This is my very first post here at Dev.to. I am curious about how companies go about running their business in the backstage and, specifically, what kind of challenges do they face in their inventory management, warehousing, workplace technologies, and overall business systems. There have been plenty of times that I witnessed how little operational inefficiencies turn into big business problems when left untreated for too long. I intend to share my observations and learnings regarding the topics of inventory management, asset management, workflow improvement, and business systems used by companies to keep themselves organized and efficient. Please note that I am not here to pretend having all the right answers. It's simply an attempt at learning and exchanging ideas within the industry. See you around!

EveryPlate is an actual budget meal kit whose plates taste delicious. Options and ingredients are fewer, but simplicity can also be a virtue.

From battery life to privacy, there are many hurdles to the idea taking off.

These are the cleaning robots, water monitors, and toys actually worth buying for pool season.

I added real-time activity logging and security scoring to my Claude Code dashboard The problem with just seeing costs Knowing how much you spent is useful. But it's not enough. The real question is: what is your AI actually doing? Which files did it read? Which commands did it run? Is your environment even safe to run it in? I couldn't answer any of those. So I built the answers in. What's new in v0.1.17 Activity Log — see every action in real-time Claude Code logs everything via hooks. Every file read. Every command executed. Every API call. Risk-labeled. Timestamped. Live. Set it up once in ~/.claude/settings.json : { "hooks" : { "PostToolUse" : [{ "matcher" : ".*" , "hooks" : [{ "type" : "command" , "command" : "curl -sf -X POST http://localhost:3000/api/actions -H 'Content-Type: application/json' --data-binary @- 2>/dev/null || true" }] }] } } Then open http://localhost:3000/activity . Watch your AI's actions stream in real-time. This is the audit layer AI agents have been missing. Security Score — how safe is your Claude Code environment? Scored out of 100. Checks 7 things: Is Bash(sudo *) in your allow list? (-20) Is ~/.ssh/** in your deny list? (-20) Is Bash(curl *) unrestricted? (-15) Are .env files protected? (-15) Is strictMode enabled? (-10) Is Bash(rm *) restricted? (-10) Are hooks configured? (-5) I scored 90/100. What's yours? The point isn't to shame anyone. It's to make the invisible visible — so you can make informed decisions about what your AI is allowed to do. Try it npm install -g @notenkidev/claude-token-dashboard claude-token-dashboard Open http://localhost:3000 GitHub: https://github.com/notenkitoclient-cpu/claude-token-dashboard This started as a simple token counter. It's becoming something bigger — an observability layer for AI agents. More coming.

I recently rebuilt my homelab from scratch. The goal was simple: one machine, everything containerised, zero exposed ports, GPU-accelerated local AI, and a fully automated backup setup. No cloud subscriptions for the tools I use every day. This is the full technical breakdown — what I'm running, how it's wired together, and the hard-won fixes that cost me hours so you don't have to repeat them. What I'm Running Eight services, 26 containers, one machine: Service Purpose Portainer Docker management UI Uptime Kuma Service monitoring (7 monitors) NocoDB Self-hosted Airtable — CRM & leads n8n Workflow automation Open WebUI Local AI chat interface Ollama Local LLM inference (GPU) AFF!NE Collaborative docs & whiteboards Plane Project management (roadmaps, sprints) Duplicati Encrypted daily backups Cloudflare Tunnel Zero Trust secure access — no open router ports All external-facing services sit behind Cloudflare Zero Trust with email OTP.

It is time to put my proposition made in my previous blog post to the test. Is it possible to spec an application for execution by an agent without encoding it in source? Let's find out. One type of application every knowledge worker is familiar with is task management. Every task has a lifecycle status, dependencies on other tasks, and a history of progress. Let's give agents their own. TaskTrack is a simple but non-trivial task management system variant implemented as a Specify spec. It goes beyond checkbox-based to-do lists that agents sometimes use internally and mimics the key system features listed above. TaskTrack defines two procedures: a "Plan Authoring Run" to create an interconnected set of tasks from requirements and a "Plan Execution Run" to advance a previously authored plan toward completion. One execution run might not always be enough to achieve completion, because TaskTrack allows requesting human feedback and incorporating it during the next execution run. Furthermore, every execution run is divided into "Task Processing Run" sub-procedures to allow for advanced agent context management. TaskTrack implements all of this in less than 300 lines of text. If the implementation used source code, then, depending on the programming language, this would be enough space to implement only the required file I/O operations (TaskTrack uses files for simplicity, not a database). Natural language can easily become quite bloated, but a stringent, scientific writing style and extensive use of what the Specify standard offers can effectively counter that. The official test is, how could it be any other way, the implementation of yet another uninspired Breakout clone. The requirements, the completed TaskTrack plan, and the deliverable are contained in the repository. If you want to run the test yourself, the included README file contains the necessary information, including the launch prompts for both the authoring agent and the execution agent. Please note how both

All tests run on an 8-year-old MacBook Air. All results from shipping 7 Mac apps as a solo developer. No sponsored opinion. HiyokoKit's MTP file manager includes QuickLook preview. Press Space, see the file. Native macOS behavior in a Tauri app. Here's how it works — and why it's worth doing. What QuickLook Is QuickLook is macOS's built-in file preview system. Press Space on any file in Finder — that's QuickLook. It handles images, PDFs, videos, and documents without opening separate apps. For a file manager, QuickLook preview is table stakes on macOS. Users expect it. If it's missing, the app feels unfinished. Triggering QuickLook from Rust The qlmanage command-line tool can trigger QuickLook from any process: use std :: process :: Command ; #[tauri::command] async fn preview_file ( file_path : String ) -> Result < (), AppError > { Command :: new ( "qlmanage" ) .args ([ "-p" , & file_path ]) .spawn () .map_err (| e | AppError :: Preview ( e .to_string ())) ? ; Ok (()) } qlmanage -p opens a native QuickLook preview window for the specified path. That's it on the Rust side for local files. For MTP Files: Download First, Preview, Cleanup Files on an Android device don't have a local path — they live on the device over MTP. The flow is: download to a temp file → preview → clean up. #[tauri::command] async fn preview_mtp_file ( device_path : String , filename : String , ) -> Result < (), AppError > { // Download to temp let temp_path = std :: env :: temp_dir () .join ( & filename ); download_from_device ( & device_path , & temp_path ) .await ? ; // Open QuickLook Command :: new ( "qlmanage" ) .args ([ "-p" , temp_path .to_str () .unwrap ()]) .spawn () ? ; // Schedule cleanup after delay let temp_clone = temp_path .clone (); tokio :: spawn ( async move { tokio :: time :: sleep ( Duration :: from_secs ( 30 )) .await ; std :: fs :: remove_file ( temp_clone ) .ok (); }); Ok (()) } 30 seconds gives the user time to view before cleanup. For large files (RAW photos, videos), y

Most of us use AI coding tools in a very normal way. We paste an error, ask for a fix, paste a file, ask again, run a command, paste the output, and keep going. After some time, we get a message saying something like you are out of tokens or you have reached your message limit . Most of the time, the reason is tokens. What is a token? A token is a small piece of text the model reads or writes. It can be a word, part of a word, a symbol, or spacing depending on the language and context. The model does not see text exactly like we do. It breaks everything into tokens first. So when you send a message, you are sending input tokens. When the model replies, it creates output tokens. If your coding agent reads files, terminal logs, docs, diffs, and old chat history, that can also become input tokens. What is a context window? The context window is the amount of text the model can keep in view at one time. It includes your message, the previous conversation, files, tool output, system instructions, project rules, and the model's own reply. Some models can hold a lot now. 200K tokens is already common in many coding workflows. Some newer models can go near 1M tokens. That sounds huge, and it is huge. But it does not mean you should always use it. Roughly speaking, 1M tokens can be hundreds of pages of text. It can be a big part of a codebase, many docs, or long chat history. But the model still has to read through that text. More context can mean more cost, more waiting, and more chances for the important thing to get buried. A rough mental model: Context size What it might hold 32K tokens A few files, a long bug report, or a small feature discussion 128K tokens Many files, long logs, or a decent chunk of project docs 200K tokens A large debugging session with files, logs, and history 1M tokens Hundreds of pages, big docs, or a large slice of a codebase This is not exact. Different languages, code, spacing, and tokenizers change the count. But it gives you the idea. Large c

I work on a computer all day. Multiple projects, lots of switching, constant interruptions. A while back I noticed I was losing track of my own work. Not really the big things but mostly the small stuff. The decision I made on Tuesday about why I structured something a certain way. The thing I was halfway through when a Slack message pulled me away. The task that never made it onto any list because it felt too small to write down (but I ended up forgetting about after lunch until 2 days later). By Friday I'd look back at the week and genuinely struggle to piece together everything I actually did. I tried obsidian (and still actively use it). I also tried just being more disciplined. None of it fully stuck because the friction of capturing things manually meant I only ever captured the stuff I already remembered. The messy ad-hoc stuff that actually eats a lot of my time never made it anywhere. I'm curious if other people deal with this. Not the big project management stuff because that's mostly solved, but rather, the stuff in between. The context that lives in your head and disappears the moment you get interrupted. How do you handle it?

I Read Your AI Agent Logs So You Don't Have To: A $149 Service That Beats Another Dashboard What if the cheapest fix for your broken AI agent is a stranger reading 40 hours of traces for $149? I spent the last month doing exactly that — reading roughly 40 hours of production logs from teams running LangGraph, CrewAI, and AutoGen agents for paying customers. Not building observability dashboards. Not comparing LangSmith vs Langfuse. Reading the actual traces and writing up what was wrong, what to fix, and in what order. Three observations from those 40 hours: The dashboard was never the problem. Every team already had LangSmith or Helicone or a homegrown equivalent logging every LLM call. None of them were reading the logs. The "fix" was almost always one of seven patterns. I kept seeing the same shapes — stuck retry loops, idempotency gaps, tool-call argument drift, etc. — dressed up in different framework jargon. The teams that asked for "another tool" were the ones least likely to use it. They had 14 tools. The teams that paid for an hour of my time were the ones who said "I don't have time to look at this myself." That second group is who I'm now building a $149 service for. Here's why I think it works, what the deliverable looks like, and where the limits are. Why a $149 fixed-fee reading and not an hourly rate I tested three pricing models against the same deliverable: a written diagnostic of an agent's last 7 days of traces, prioritized fixes with code-level examples, and a 30-minute async follow-up. Model Conversion Avg revenue / inquiry Notes $200/hr (estimated 3hr) 2/40 inquiries $15 (lost 38 to sticker shock) Freelance default, fails on cold traffic $1,500 flat project 0/40 inquiries $0 Above the "I'll just keep it broken" threshold for most small teams $149 fixed diagnostic 11/40 inquiries $41 Below "another contractor" threshold, above "free advice" The $149 number is the inversion point — low enough that a stressed eng lead can expense it without a meet

Anyone who works with Ruby on Rails knows that, despite the framework being incredible for productivity, there are some classic workflow deficiencies that haunt almost every project. You are focused on writing code, but suddenly you need to open an external tool like Postman to test a route. Then, you run a complex script to generate a static database diagram. And at the end of the day, you still need to manually update the API documentation, which will inevitably become outdated in the next sprint. This constant context switching and manual maintenance generates enormous friction. To cover these deficiencies, I developed three gems that bring these tools inside your application. They are so practical that they quickly become indispensable in any Rails project. Meet each one of them: 1. rails-api-docs : The End of Outdated Documentation The deficiency: API documentation always starts with good intentions, but as the system evolves—new routes, parameters, and response fields—it quickly stops representing reality. Keeping this updated manually is repetitive and frustrating work. The solution: The rails-api-docs gem solves this by leveraging what Rails already knows. It inspects your routes, controllers (via AST analysis using Prism), and the ActiveRecord schema to automatically generate the first draft of your documentation. Everything is saved in a single YAML file ( config/rails-api-docs.yml ), which serves as the single source of truth. Why it is indispensable: Append-only strategy: When adding new routes and running the generator, the gem only appends what's new. Your descriptions, custom examples, and tags are never modified or deleted, making the documentation a living document. Zero development friction: You edit the YAML in one window and view the updated documentation in the browser at localhost:3000/rails/api-docs instantly, with no build step required. For production, it exports a single static HTML file without any external dependencies. 2. rails-http-lab
