Hey DEV community, I built A2Z Edit — a free, private, and browser-based toolkit for images, PDFs, OCR, QR codes, and file management. 🔧 What it does Image Tools: Remove background, resize, crop, compress, convert between formats (JPG, PNG, WebP, AVIF, HEIC), add watermarks, blur/pixelate sensitive regions, create collages, and view/strip EXIF metadata. PDF Tools: Merge, split, arrange, compress, watermark, sign, crop, edit text, redact, and convert PDFs to/from JPG, PNG, Word, and CSV/Excel. OCR Tools: Extract text from images and PDFs with support for English, Arabic, and bilingual English+Arabic recognition. QR Tools: Generate customizable QR codes and scan them from images or your camera. File Tools: ZIP creator/extractor, Base64 encoding, and color converters (RGB, HEX, HSL, CMYK). 🔒 What makes it different Your files never leave your browser . Everything runs client-side. No uploads, no servers, no signup, no limits. I built this to be fast, private, and reliable. No ads. No freemium. Just tools that work. 🚀 Check it out Try it here: https://www.a2zedit.com Would love to hear your feedback or suggestions for new tools. Let me know what you think in the comments! Note: This was built with Next.js, runs entirely in the browser, and scores 100/100 on Lighthouse (Performance, Accessibility, Best Practices, SEO).

About a year ago, I was building a terminal-based workflow manager called Glyph.Flow. It was mostly a learning project. I wanted to understand Python better, experiment with Textual, think about commands, state, configuration, logging, and all the small architectural decisions that suddenly appear when a script stops being a script. Somewhere between then and now, the workflows became a little more real. For my Master's thesis, I built a data pipeline to construct and process a cross-national research database from multiple sources. It had a clear purpose: take heterogeneous input data, transform it consistently, validate important assumptions, and produce the dataset I needed for the analysis. And it worked. But this is no longer enough. I am not rebuilding it because the original system failed. I am rebuilding it because the question changed: My Master's thesis needed a pipeline. My PhD will need research infrastructure. And I am slowly discovering that these are not the same thing. A pipeline can be finished There is something comfortable about building software for a well-defined research project. You know the research question. You know most of the variables you need. You know which datasets are involved. You can define the transformations, produce the outputs, validate them, run the analysis, and eventually say: Done. Of course, research is never really that clean. Data sources change. Weird edge cases appear. A country disappears from one dataset. Another source changes a variable name. An indicator turns out to mean something slightly different than you thought. But there is still a boundary around the problem. A PhD changes that boundary. Now I have to think about a system that may need to survive several years of research, new questions I have not formulated yet, datasets I have not discovered yet, and methodological decisions I will probably reconsider more than once. Suddenly, "Does it work?" becomes a surprisingly weak design criterion. The more useful

I'm Nadia, and I built HEICtoPDF — it turns iPhone HEIC photos into PDFs without the file ever leaving the browser. I maintain it myself as an indie side project, so read this as a maker post, not a neutral review. The interesting part of building it wasn't the conversion. It was deciding, early, that nothing gets uploaded — and then living with everything that decision took away. Why "no upload" was the starting point, not a feature Look at who actually needs HEIC turned into PDF. An iPhone has shot HEIC by default since iOS 11, and a lot of upload forms still won't take it: government portals, visa and benefit applications, job application systems, insurance and expense claims, print services. So the file someone is converting is usually a photo of a passport, a driver's licence, a signed form, a utility bill with their address on it, a medical receipt. That is the whole population of this tool. "Drop your ID onto our server and we'll send you back a PDF" is a bad shape for that job, even when the server is honest and deletes things on schedule. The user has no way to verify any of it. Doing the work locally is the only version of this where the promise is structural rather than a policy statement. That framing is easy to write on a landing page. What follows is the bill. What the constraint costs A file size ceiling. 10MB per input file. On a server you scale past this by renting a bigger machine; in a browser tab you're spending someone else's device memory, on hardware you know nothing about, and the failure mode isn't a 500 — it's the tab dying while they watch. So the cap is set where it is on purpose, and it does turn some files away. A page ceiling on merging. You can convert a batch and then combine the results into one multi-page PDF, up to 30 pages. Same reason. Thirty pages covers the actual use case — "my landlord wants all of this as one file" — and stops well short of someone dropping a holiday album in. Lossy output, and I have to say so.

Most model benchmarks tell you how smart the model is on the first attempt, which is almost never the problem in production. The real problem is what happens on the 120th attempt, when the same kind of input shows up again and nobody is watching. I spent 48 hours running the same classification task against a free model on a free server, and the drift taught me more than accuracy ever did. The Setup I'd Run Again The workload was dull on purpose: ten support tickets, three labels, one prompt template. Every hour the job asked the model to classify one ticket and logged the raw output, so each ticket appeared about twelve times. It was not a benchmark of intelligence; it was a probe of stability, and stability is what automation actually needs. I ran the whole thing on MonkeyCode's free server option, using the free model access for inference, because a cheap long-running job is exactly the scenario that setup is for. Disclosure: This article was prepared as part of MonkeyCode's product outreach. The rest is about what the probe caught, not about quotas or latency, so treat my numbers as one operator's field notes. The Probe Code (Steal This) A probe is only honest if it writes down everything, including the outputs you didn't ask for. The script below hashes every response, tries to parse a label, and appends one JSON line per run, so nothing interesting ever gets lost. import hashlib , json , time LOG_PATH = " drift.jsonl " LABELS = ( " bug " , " feature " , " question " ) def stable_hash ( text ): return hashlib . sha256 ( text . strip (). encode ()). hexdigest ()[: 12 ] def parse_label ( raw ): # Accepts JSON or plain prose; returns None when the format is unknown. try : return json . loads ( raw ). get ( " label " ) except json . JSONDecodeError : found = [ label for label in LABELS if label in raw ] return found [ 0 ] if found else None def record_run ( run_id , ticket_id , raw , expected ): entry = { " run " : run_id , " ticket " : ticket_id , " hash " : stabl

A GitHub Copilot spending limit is a monthly budget, set in billing settings, that caps metered AI credit consumption for an enterprise, an organization, a cost center, or a single user. Creating one takes about two minutes. Knowing what it stops takes longer, and the gap between those two things is where most surprise Copilot invoices live. Two facts account for nearly all of them. On enterprise, organization and cost center budgets, the setting that actually blocks usage is off by default, so a budget in its default state is an alert rather than a limit. And no budget of any kind caps seat cost, because seats are license-based rather than metered. A spending limit governs what happens after the included credit pool runs out, and nothing before it. How to set a GitHub Copilot spending limit Budgets live in the billing settings of the account that pays. Enterprise owners and billing managers can set every budget control, including enterprise, cost center and user-level budgets. Organization owners can set a budget for their own organization, and that budget can only restrict usage further below whatever an enterprise admin has already set. It cannot raise the ceiling. The mechanics are the same at every level. Choose the budget type, which determines the metered product being measured. Choose the scope, which determines whose usage counts against it. Enter a monthly amount. Then, if the option appears, enable Stop usage when budget limit is reached and switch on threshold alerts at 75, 90 and 100 percent. That single checkbox is the whole exercise. Skip it and you have built a notification. What a GitHub Copilot spending limit actually caps GitHub splits its products into license-based and metered. For license-based products, which include Copilot seats, setting a budget does not prevent usage above the amount. It only alerts. For metered products, which include Copilot AI credits, a budget can prevent usage once the threshold is reached. The consequence is worth st

If you searched for a klogg alternative , you probably already know klogg is good. It is fast, it is free, it is open source, and it runs on Windows, macOS and Linux. Most people who go looking for something else are not unhappy with klogg as a viewer. They are unhappy with one specific moment in their day: Opening the file again. You investigated a 48GB log yesterday. You closed it. This morning your colleague asks about a different error, and you have to wait through the whole index build a second time. On a USB HDD that is nine minutes of staring at a progress bar — and while it builds, klogg only shows you the beginning of the file. That is the problem this article is about. Below is a measured comparison on a real 47.73GB file, including the rows where klogg wins . The test File OpenStreetMap Japan japan-latest.osm — 47.73 GB, 892,239,125 lines Machine MacBook Air / Apple M4 (10 cores) / 32GB RAM Storage (measured with dd ) USB HDD 0.10 GB/s ／ USB SSD 0.41 GB/s ／ Internal SSD 3.29 GB/s Versions klogg 24.11.0 ／ UwView Pro Search hit counts were verified to match exactly across klogg, UwView Pro, and a direct search of the raw file — so we know both tools are answering the same question. The numbers klogg 24.11.0 UwView Pro Ratio First open HDD ~9 min ／ USB SSD ~110 s ／ Internal SSD ~15 s — every time HDD 10.6 min ／ USB SSD 138.5 s ／ Internal SSD 23.3 s — first time only klogg wins Reopening Same as the first open (re-indexes every time) 0.01–0.07 s ~1,250–50,000x Search, literal "Tokyo" ~585 s ／ 120–135 s ／ 15–20 s 74.8 s ／ 14.3 s ／ 5.1 s ~7.8x ／ ~9x ／ 3–4x Search, regex "Tok[yi]o" ≈ literal (I/O bound, pattern-independent) 29.8 s (USB SSD) ／ 11.0 s (Internal SSD) ~4.4x ／ ~1.5x Disk used to keep the file 48 GB (original required) 5.3 GB (original can be deleted) 1/9 Two things are worth saying plainly. klogg opens the file faster the first time. UwView Pro is slower on the first open because it is building a compressed cache while it reads. That is a real cost a

LINE published an official MCP server for its Messaging API, which means an AI agent can now drive a LINE Official Account directly — sending messages, broadcasting promotions, and pushing Flex Message cards without writing any API code. I set it up with Codex and worked through every capability the server exposes, from creating a fresh account to delivering a message to a real phone. This guide is the result: a complete walkthrough, and an honest account of the three places where the documentation and reality diverge. Key takeaways MCP is agent-agnostic. The same LINE server works with Codex, Claude Desktop, and Cline — only the config file format changes, from TOML to JSON. Codex stores MCP config in TOML , at ~/.codex/config.toml . Most guides assume the JSON format used by Claude Desktop, which is the single most common setup mistake. Verified account and API-capable account are different things. A free account can use the Messaging API, but get_follower_ids returns 403 Forbidden until the account is verified or on a premium plan. Official security advice can conflict with official features. LINE's example config disables npm install scripts, which also prevents the headless browser that the rich menu tool depends on from being installed. Agents have habits. Codex is a coding agent first: asked in natural language to build a rich menu, it wrote a Node script instead of calling the MCP tool. Naming the tool explicitly in the prompt fixes it. Broadcasts cannot be recalled. Set default_tools_approval_mode = "writes" so the agent asks before any send. Every screenshot comes from the actual working setup, including the errors.

The criticism of this is everywhere. Open any Go thread long enough and someone will show up to perform the same ritual: "Go projects become messy. There's no framework to guide you. Nest, Django, Spring, they all tell you exactly where to put things. Go? It just says 'organize it somehow.'" It's a fair criticism. Go is unusually permissive about structure. I just think blaming Go for a messy codebase is like blaming the empty document for the bad essay. I don't think Go encourages bad architecture but rather it exposes it. The Hell Is A Perfect Folder Structure?? Ask a hundred Go developers where to put business logic and you'll get a hundred answers (and 200 opinions). "Should I use internal/ ?" "Is everything supposed to live under pkg/ ?" "Should I follow Clean Architecture?" "What about the cmd/ directory?" We spend so much time debating folder structures as if the arrangement of directories somehow determines code quality. As if renaming utils/ to pkg/shared/ is going to save us. God. folders don't create architecture. Dependencies do. You can meticulously organize your project like this: my-app/ cmd/main.go internal/ handler/ service/ repository/ pkg/domain/ pkg/utils/ And still write tightly coupled garbage. Handlers calling repositories directly. Services importing database drivers. Business logic mixed with HTTP concerns. Everything circular. Beautiful folders, though. Very organized looking on GitHub. There are better projects I've seen with just 5 packages, they just don't screenshot as well. Architecture Is About Dependency Direction The architecture is about making intentional decisions about how code depends on other code. Have a look at this: HTTP Handler ↓ Business Service ↓ Data Repository This isn't sacred because of folder names. It's valuable because of what it represents: The handler only knows how to translate HTTP The service only knows business rules The repository only knows how to fetch data Each layer depends on the layer below, never upw

Most "free online tools" have a dirty little secret: the moment you drop a file in, it gets uploaded to someone else's server. Your tax PDF, your ID photo, your client's contract — all sent off to be processed on a machine you'll never see, by a company whose privacy policy you didn't read. For a quick image resize, maybe you don't care. But it adds up. And the wild part is that for most everyday tasks, that upload is completely unnecessary. Modern browsers are powerful enough to do the work right on your own device — no server round-trip, no copy of your file sitting in someone's cloud. Here's how that works, and how to actually use it. Why do so many tools upload your files? Two reasons, mostly. The first is habit: it's easier for developers to send a file to a server, run some code there, and send the result back. The second is business: once your file is on their server, they can log it, analyze it, or use "free" as a funnel toward a paid plan. Watermarks, file-size limits, and "sign up to download" walls all come from this model. The alternative — processing files client-side , meaning inside your browser — has quietly become viable for a huge range of tasks thanks to two technologies: JavaScript (which every browser runs) and WebAssembly (which lets browsers run fast, compiled code at near-native speed). Together they can compress an image, merge a PDF, or transcode data without your file ever leaving the tab. What you can do entirely in your browser You'd be surprised how much works locally now: Images — compress, resize, convert between PNG/JPG/WebP, remove backgrounds, strip metadata. PDFs — merge, split, rotate, compress, and convert to or from images. Text and code — format or minify JSON, count words, change case, generate QR codes, encode/decode Base64. Everyday math — loan, BMI, age, and currency calculators that don't need a server at all. None of these require your data to travel anywhere. The tool loads once, and from then on it's just your CPU doin
