Disk full alerts at 2am? Learn the exact commands to find what's eating your Linux server's disk space and fix it fast. You get the alert: disk usage at 94%. Your app starts throwing errors, logs stop writing, and databases refuse to accept new rows. Finding the culprit fast matters — but on a server with millions of files, knowing where to look is half the battle. Here's a systematic approach to track down disk hogs in minutes, not hours. Start With the Big Picture: df Before you dig into directories, confirm which filesystem is actually full. Run: df -h — shows all mounted filesystems with human-readable sizes df -h / — focus on the root filesystem df -i — check inode usage (a filesystem can be 'full' even with free space if inodes are exhausted) Pay attention to the 'Use%' column. If you see 100% on /var or /home but not /, that tells you exactly which mount point to investigate. Inode exhaustion — df -i showing 100% — is easy to miss and causes the same symptoms as a full disk, so always check both. Drill Down With du Once you know which mount point is full, use du to find the largest directories. Start from the top of that mount point and work down: du -sh /* 2>/dev/null — sizes of every top-level directory, errors suppressed du -sh /var/* 2>/dev/null — drill into /var if that's the culprit du -ah /var | sort -rh | head -20 — list the 20 largest files and folders inside /var The pattern is always the same: run du -sh on the suspicious directory, find the largest subdirectory, repeat one level deeper. You'll usually hit the real culprit within three or four iterations. Common offenders are /var/log (runaway logs), /var/lib/docker (unused images and volumes), and /tmp (applications that don't clean up after themselves). Find Large Files Directly With find Sometimes a single enormous file is the problem — a core dump, a forgotten database export, or a log that rotated incorrectly. Use find to surface files above a size threshold: find / -xdev -size +500M -ls 2>/de

A background noise removal workflow is easy to describe and much harder to make trustworthy. The superficial version is: upload a file, run processing, download the result. The harder version is product design: what does a person need to know before committing to a result, paying for an export, or spending a limited processing allowance? A preview-first workflow answers that question by making uncertainty a first-class part of the system. Instead of asking people to trust a long-running operation, it gives them a bounded way to hear a representative outcome before they choose what happens next. This article lays out the design principles behind that approach for stored audio or video uploads. It is not a call-time or capture-time filter. The central workflow is: upload → compatibility check → preview → same segment before/after → export choice That sequence looks simple, but each boundary carries product and engineering consequences. Start with a decision, not a processing feature A preview should help a user make one specific decision: “Is this result useful enough for me to continue?” That framing prevents a common mistake: treating a preview as a small free version of the full product. A useful preview is not merely a shorter job. It needs to be comparable, understandable, and tied to the next action. For background noise removal, the most defensible comparison is a matched segment: The source and processed audio use the same time range. Playback controls make the comparison obvious. The user can choose whether to continue only after hearing that bounded example. If the before and after samples use different moments, the product is asking the user to infer too much. A quieter section in one clip can appear better even when the processing change was minor. Matching the segment removes that ambiguity and keeps the decision grounded in what the user actually heard. Put compatibility before expectation Compatibility belongs near the beginning of the workflow, before

Tesla has officially launched the Cybercab, its autonomous vehicle with no steering wheel.

jQuery, created by John Resig and released in 2006, is a JavaScript library that simplifies HTML manipulation, event handling, animation, and Ajax. It enabled easier web development by providing an accessible API across browsers. While its use has declined with the rise of modern frameworks, jQuery remains prevalent on a significant portion of websites today. By Daniel Curtis

In this post I'll talk about my brief experience with muse , Meta's LLM harness for developers, as well as Muse Spark 1.3, their latest frontier-level model. The Bad I'll start with the bad, just because I like to end with the positive :) Skill Usage It's not that good following skills. If the skill has disable-model-invocation , sometimes it refuses to launch it, even if you manually call it. I think it happens when you call the skill mid-sentence, but it's not consistent. It's also not as good as other models at following skill instructions. It seems to get confused more often. For example, I have one skill that will address an issue from GitHub to PR. In Claude (Opus 5) and Cursor (Grok 4.6) it works perfectly. The first step is grilling the issue, after that's finished, the next step is autonomous, plan, implement with TDD, review and open PR. With Muse Spark 1.3, sometimes the skill will not continue and I have to nudge it for the next step, just saying something like "continue" is enough, but surely is annoying. Formatting The output is not great. Sometimes it will show me raw markdown, sometimes not. It's not consistent. Sandbox Having a sandbox is good, but in this case, it's a bit too restrictive. For example, I'm working with a Firebase project and I want to use the emulators. Well, too bad. The sandbox doesn't allow you to run files outside your workspace or use external ports. That would be great if I could add exceptions or some kind of configuration, but you can't. You are basically forced into --yolo mode if you don't want to be prompted on repeat for the same things over and over. What's sad is that even if you want to give them access, the models will just get stuck asking for permissions for the same thing over and over again and eventually they will just be stuck doing nothing. The Good Not everything is bad, of course. With a bit of effort I think it's actually quite usable. Price The main reason I decided to try the model. The subscription plan

Introdução Muitas linguagens como C#, Java, entre outras são descritas como orientadas a objeto, possibilitando o paradigma Programação Orientada a Objeto (POO). No entanto, quando falamos de JS, sabemos que por mais que existam objetos, ela é dita como uma linguagem orientada a protótipos, mas o que de fato isso significa, qual problema isso resolve e como muda a maneira como programamos? O problema Tanto a orientação a objeto quanto a orientação a protótipo lidam, entre outras coisas, com a questão de como a herança vai funcionar em determinada linguagem e é justamente nesse ponto que as duas abordagens mais se diferem. Em linguagens orientadas a objetos as classes de fato existem, contendo propriedades, métodos e servem como molde para a criação de objetos. Com isso, todo objeto criado a partir de uma classe herda suas propriedades e métodos ficando acessíveis para uso. Como não existem Classes de fato em JavaScript, a herança ocorre de maneira diferente, de objeto para objeto, ligados através da propriedade [[Prototype]] que possui uma referência ao seu protótipo, fazendo com que determinado objeto herde de seu protótipo propriedades e métodos que nunca foram definidos nele. Exemplo com array Quando criamos um array, seja de forma literal com [], ou de forma explícita com new Array(), o resultado final é o mesmo: um array cujo [[Prototype]] aponta para o Array.prototype. Essa propriedade .prototype possui um objeto contendo todas as propriedades e métodos que o [[Prototype]] referencia, possibilitando que todos os arrays possam usar métodos como push, pop, map, filter… Com isso, se irmos além e conferirmos o [[Prototype]] do Array.prototype vamos perceber que ele aponta para o Object.prototype que contém propriedades e métodos também disponível em todo essa cadeia que chamamos de prototype chain . Por fim, se tentarmos visualizar o protótipo do Object.prototype veremos que é null, pois ele representa o último elo dessa cadeia. Teste o código abaixo para ver na p

I wrote "just use a match statement, it's fine" three times before I stopped saying it. It is fine, right up until an enemy needs a fourth state and two of the transitions start depending on each other. Here is what actually cost time building enemy AI for a wave-based game, in the order it bit me. Lesson 1: the match statement is fine until state 4 A two-state enemy — chase, attack — is genuinely not worth a framework: func _physics_process ( delta : float ) -> void : match state : State . CHASE : velocity = ( player . global_position - global_position ) . normalized () * speed if global_position . distance_to ( player . global_position ) < attack_range : state = State . ATTACK State . ATTACK : attack_timer -= delta if attack_timer <= 0.0 : do_attack () state = State . CHASE The moment a third and fourth state show up — hurt, dead, stagger, windup — the match block stops being one enemy's logic and becomes a grid of every state times every other state it might transition to. That grid is where the bugs live, not in any single state. Lesson 2: the bug is never inside a state, it's in the transition Every state-machine bug I actually spent time on was the same shape: state A left some flag or timer set that state C didn't know to check. An enemy stuck mid-attack-animation forever, still receiving hits, was not a bug in the attack state — it was the hurt state interrupting attack without cleaning up attack_timer or resetting the animation. The fix that made these bugs findable is giving every state an explicit enter and exit , and never mutating another state's data directly: func change_state ( new_state : State ) -> void : if new_state == state : return _exit_state ( state ) state = new_state _enter_state ( new_state ) func _exit_state ( s : State ) -> void : match s : State . ATTACK : attack_timer = 0.0 sprite . stop () func _enter_state ( s : State ) -> void : match s : State . HURT : velocity = Vector2 . ZERO hurt_timer = HURT_DURATION sprite . play ( "hurt" ) On

If you are an active user of AI-powered IDEs like Cursor, VS Code with Copilot, or Windsurf, you already know the sinking feeling of seeing this notification: "You have used 100% of your fast premium requests for this billing cycle." Suddenly, your snappy, context-aware coding assistant slows to a crawl or starts racking up expensive pay-as-you-go API bills. At the same time, you are likely paying $20/month for a ChatGPT Plus or Team subscription that sits underutilized in a browser tab. You use it for general questions, but it lacks direct, real-time access to your local codebase, forcing you to engage in a tedious dance of copying and pasting code blocks. What if you could bridge this gap? What if you could let ChatGPT Web do the heavy reasoning and planning using your local context, while saving your premium IDE tokens for fast auto-completions ? In this article, we’ll explore a highly novel, intermediate-level setup that does exactly this. By leveraging the Model Context Protocol (MCP) , Node.js , and secure Cloudflare Tunnels , you can route heavy code-planning tasks directly to your web-based ChatGPT Plus subscription safely and completely free of extra token charges. The Philosophy: Let ChatGPT Think, Let Your IDE Work When building complex software with AI, your workflow generally splits into two distinct phases: Reasoning & Planning (High Token Usage): This is where you ask the AI to read 10 source files, understand the architecture, design a new feature, or find a subtle bug. This consumes massive amounts of context window tokens. Execution & Autocomplete (Low Latency): This is where the AI writes single lines of code, refactors a function, or autocompletes your imports. This requires fast, inline API queries. Paying premium API rates (per token) for Phase 1 is incredibly expensive. This is where this open-source MCP bridge project shines. It exposes a read-only view of your local project as an MCP server. Your web-based ChatGPT (via custom GPTs or MCP int

Late August I kept seeing the name Dungeon Lootr in places it hadn't been before. I wanted to know whether the game was actually growing or whether I was just noticing it more. Turns out Roblox exposes enough public data to answer that without an API key, so I started pulling it every day. The endpoint is boring in the best way: curl "https://games.roblox.com/v1/games?universeIds=9656201728" You get back visits , playing , favoritedCount , updated and a few other fields. A second call to /v1/games/votes?universeIds=... gives you up and down votes. No auth, no rate-limit drama at once-a-day volume. Here is what a week of that looks like for this one game: Date Total visits Playing right now Favorites Approval Sep 2 4.83M — 25.5k 96% Sep 3 5.39M 10.8k 29.8k 96.1% Sep 4 6.85M 11.4k 38.6k 96.1% That is about 1.4 million more visits than when I checked yesterday, and favorites jumped by almost nine thousand. The updated timestamp moved twice in two days (Sep 2 23:06 UTC and Sep 4 00:56 UTC), so the developers are shipping while the curve is climbing rather than sitting on it. The part that surprised me: the game was created on January 31, 2026. It sat there for seven months doing nothing visible, then flipped in the last week of August. I do not have a clean explanation. No single creator video I can point to, no front-page placement I noticed. It just started compounding. I wrapped the two calls into a tiny CLI so I would stop retyping the universe ID: https://github.com/jackzhouqd/roblox-game-stats — plain Python, no dependencies. Point it at any universe ID and it prints the same table. A few caveats before anyone reads too much into this: visits is cumulative and not deduplicated. It counts sessions, not people. playing is a snapshot at the moment you call it. Hit it at 3am and you will get a different number than at 8pm. One day of movement means nothing on its own. A week of movement in the same direction is when I start paying attention. What I am doing with it: I

I wanted a microphone project with a very small brief: hear a sound, copy it, and see how close you got. That became Mimic Party Online , a browser game where each round gives you a short sound cue and one recording attempt. The cue might be a meme clip, an animal call, a machine noise, or something that is hard to describe without making the sound yourself. It looks like a toy, and it is. It also turned into a useful little audio problem. A score based only on volume would be boring, so the game needs to compare the shape of two sounds while staying fast enough to run in a browser. The round is intentionally simple The player does five things: Choose a sound pack. Listen to the reference. Record one take. Listen to the take. Read the score. The replay is important. People tend to remember the sound they meant to make. The recording tells them what actually came out. A convincing robot alarm can turn into a tired bicycle horn pretty quickly. Quick mode runs for four rounds. Survival mode gives the player three Mic lives and keeps the run going until those lives are gone. The game also has different routes, so a player can protect a streak or accept a shorter recording window for more points. The browser does the audio work The recording stays in the browser. The game uses the microphone stream, converts the take to mono PCM at 16 kHz, and extracts the values needed for scoring. The audio does not travel to a scoring server. For each take, the extractor looks at signals such as: pitch contour timing and active duration attack and energy rhythm and onset positions spectral shape The game does not use every signal for every sound. A pitched cue cares more about contour, while a machine noise depends more on its shape and attack. A rhythmic sound needs the hits to arrive at roughly the right moments. This is also why the score is more useful when it has labels. A result of 68 is not very instructive by itself. "Timing: 74" gives you something to work on in the next atte

An invite-only event in Austin, Texas, kept online fans in the dark for hours.

An email file is not just text plus a few attachments. It can contain HTML, nested MIME parts, misleading filenames, inline resources, remote tracking pixels, malformed encodings, and enough data to exhaust a browser tab. Moving parsing into the browser removes an upload from the architecture, but it does not automatically make the viewer safe. It changes the security job: untrusted content is now being interpreted next to the user’s active web session. This is the checklist I use for a local EML and winmail.dat/TNEF reader. Treat every parsed field as untrusted The sender, subject, recipient, filename, MIME type, and message body all came from a file. Render headers and filenames as text, never by concatenating HTML. The same applies to errors. A parser exception can include a filename or fragment of malformed input. Showing that message verbatim may leak data into logs or turn it into markup. Map parser failures to stable error categories, then display a controlled explanation. Normalize into one internal model EML and TNEF have different container structures, but the UI should not contain two independent security implementations. Both parsers can produce a common message model: subject, sender, to, cc, date, plain body, sanitized HTML candidate, attachments[] { safe filename, MIME type, bytes, inline flag, content ID, content location } The normalization layer is the right place to enforce per-source limits and reject unsupported structures. The viewer and download code then work against the same constrained data regardless of input format. Sanitize HTML as hostile input Email HTML was designed for mail clients, not for direct insertion into an application DOM. A conservative policy removes: scripts and event handlers; forms and interactive controls; iframe , object , and embed elements; styles and CSS URLs; unsafe protocols; executable or unexpected embedded content. Use a maintained sanitizer with a pinned version, but do not stop at its default configuration.

The agent is already in your workflow. The failed build is where it goes blind. AI coding agents have moved from novelty to daily tool. In Stack Overflow's 2025 Developer Survey, 84% of developers said they are using or planning to use AI tools in their development process, up from 76% the year before, and about one in seven professional developers now use AI agents at work every day . Among developers who have used agents at work, roughly 70% agree the agents have reduced the time they spend on specific tasks . There is one place, though, where that agent still tends to go dark: the failed CI run. The pipeline turns red, and your agent (like you) is handed a wall of log output from jobs it did not write, covering steps it did not touch. It has to reconstruct what actually broke before it can fix anything. That reconstruction is the expensive part, and it is exactly the part Latchkey is built to remove. This piece is about a clean division of labor. Latchkey's self-healing CI repairs the failures that are about your environment, not your code. For the failures that are genuinely about your code, Latchkey does not guess and patch on your behalf. Instead it hands your own coding agent a complete, structured account of the failure over the Model Context Protocol, so your agent can fix the bug with full context instead of starting from a log file. Two kinds of red build, and only one of them is yours to fix Almost every failed build is one of two things. Either the environment let you down (a flaky network, a full disk, a process killed for memory, a missing tool, configuration that drifted), or your code is actually wrong (a compile error, a failing test, a broken assertion). These two cases want opposite treatment, and conflating them is how teams end up rerunning pipelines and hoping for green. Latchkey's self-healing CI handles the first case. When a step fails on a Latchkey managed runner, Latchkey detects the failure, diagnoses the cause, and applies a fix while t

The Pipeline Became the Attack Surface For most of the last decade, we treated the CI/CD pipeline as plumbing: invisible, trusted, and mostly ignored until it broke. That assumption is no longer safe. The clearest signal came in 2025, when attackers stopped going after the software a pipeline builds and went after the pipeline itself. This week's research pass pulled together three shifts that are all landing at once: a supply-chain attack that redefined the threat model, GitHub's response in its 2026 security roadmap, a pricing change that quietly rewrites the cost math, and a persistent gap between how much teams trust AI in general and how little they trust it inside CI. Here is what the sources actually say. The tj-actions attack changed the threat model On March 14, 2025, researchers discovered that the popular tj-actions/changed-files GitHub Action had been compromised. According to Palo Alto Networks Unit 42, the action was used by over 23,000 GitHub repositories at the time ( Unit 42 ). The mechanics are worth understanding, because they explain why this matters beyond one action. Attackers injected code that dumped the CI/CD runner's memory and wrote sensitive environment variables and secrets straight into the workflow logs. They retroactively modified multiple version tags to point at a single malicious commit, so pipelines that pinned to a tag rather than a commit SHA pulled the payload ( Unit 42 ). The incident is tracked as CVE-2025-30066, described as allowing remote attackers to discover secrets by reading action logs ( GitHub Advisory Database ). The compromise did not start with tj-actions. Unit 42 traced it back through a leaked personal access token that reached reviewdog/action-setup , a dependency in the chain, with earlier steps going back to late 2024 ( Unit 42 ). In other words, the pipeline's own dependency graph was the delivery vehicle. The takeaway is not "avoid one bad action." It is that the automation running your builds is now a firs

Most "best CI/CD tools" lists are twenty logos in a table, ranked by nothing in particular, with the author's product at the top. This is not that. It is a map of the categories, what each one exists to solve, and how to tell whether you need it yet. I work at Latchkey, so I will say plainly where we sit: we are one option inside one of the six categories below, and I will tell you when we are the wrong answer. Read the rest as a map, not a pitch. A note on what is missing here: I have not invented benchmark numbers or quoted prices for tools I do not operate. Vendor pricing changes often enough that any figure I write today is wrong by the time you read it. Where a number matters, go to the vendor's own pricing page. The mistake most teams make Teams usually shop for CI/CD tools by asking "which one is best." That question has no answer, because the tools are not competing with each other. They are stacked on top of each other. A team that adopts a build accelerator to fix a slow pipeline, when the actual problem is that half their failures are flaky, has bought a faster way to fail. A team that adds pipeline observability before they have enough pipeline to observe has bought a dashboard nobody opens. The useful question is narrower: which layer is currently your constraint? Answer that, and the tool choice inside the layer is usually obvious. Here is the whole landscape in one view. Layer What it solves When it becomes your bottleneck CI platform Running the pipeline at all Never; this is where everyone starts Runners and compute Where jobs run, and how fast they start Queue time or runner cost is visible Build acceleration Doing less work per run Full rebuilds dominate your wall clock Supply chain security What the pipeline is allowed to reach You ship to production or touch customer data Observability and cost Where time and money actually go You cannot answer why last week was slow Artifacts and registries Storing what the pipeline produces You publish images

Two things are true about software delivery in 2026, and they are pulling in opposite directions. The first: AI is now writing a large share of the code that reaches your pipeline. CloudBees' 2026 State of Code Abundance Report found that AI generates or assists in writing 61% of the average enterprise codebase, and that 81% of enterprise leaders report an increase in production issues tied to AI-generated code. The same report names a confidence gap worth sitting with: 92% of leaders say they are confident in the production readiness of that code, even as the failures climb ( CloudBees, 2026 ). The second: the place best positioned to catch those failures, the CI/CD pipeline, is where teams trust AI the least. JetBrains' TeamCity team reported that 73% of organizations do not use AI in their CI/CD pipelines at all, and 78.2% do not delegate tasks to AI in CI/CD workflows, even though general AI usage in development work exceeds 90%. When asked why, 60% cited unclear use cases or value, 36% cited a lack of trust in AI-generated results, and 33% cited data privacy concerns ( JetBrains TeamCity, 2026 ). That is the trust gap. More machine-written code is arriving, more of it is breaking in production, and the pipeline that should be the safety net is the one room teams will not let automation into. This piece is about why that hesitation is rational, and what automation has to look like to deserve a different answer. Why the pipeline is different The JetBrains analysis put its finger on the reason cleanly: development workflows tolerate experimentation because feedback is immediate and cheap. CI/CD is the opposite. It demands consistent, reproducible signals, and the cost of an error is high. A coding assistant that guesses wrong wastes a few seconds of your time. A pipeline that guesses wrong can hide a real defect, ship it, or erode the one thing a pipeline exists to provide: a trustworthy answer to the question "is this build good?" So the bar for automation in CI/

The first half of 2026 reset two things at once for engineering teams: what continuous integration costs, and what it takes to keep delivery stable while AI pushes more change through your pipelines than ever. Those two stories are connected, and the connection is the part worth your time. The pricing reset On January 1, 2026, GitHub reduced prices for GitHub-hosted runners by up to 39%, with the size of the cut depending on the machine type ( GitHub Changelog ). Standard hosted-runner usage on public repositories stays free, as it was before. The DevOps publication SamExpert documented the specific per-minute moves. A Linux 2-core runner dropped about 25% (from $0.008 to $0.006 per minute). A Windows 2-core runner dropped about 38% (from $0.016 to $0.010). A Linux 64-core arm64 runner dropped about 39% (from $0.160 to $0.098) ( SamExpert ). If your CI runs mostly on hosted runners, that is real money back, and it is worth recalculating your monthly estimate against the new rates rather than assuming last year's numbers still hold. The same December 2025 announcement carried a more controversial proposal: a $0.002 per-minute charge for self-hosted runner usage in private repositories, scheduled to start March 1, 2026 ( DevClass ). GitHub framed it as ending a cross-subsidy, where revenue from hosted runners was effectively underwriting the cost of operating Actions for everyone, and said the large majority of customers would see no change to their bill. The reaction from developers who run CI on their own hardware was sharp, with some publishing the monthly figures they expected to owe for compute they already pay to operate themselves. Within about a week, GitHub posted that it was postponing the self-hosted billing change to re-evaluate its approach ( SamExpert ). Postponed, it is worth being precise here, is not the same as withdrawn. There is no new date and no guarantee the charge returns in its original form, but there is also no statement that it is gone for

The first half of 2026 rearranged three things at once for teams that live in GitHub Actions: what CI costs, how it is secured, and how much of it a machine can now do on its own. None of these landed cleanly. Prices went down for most people while a new platform charge quietly went up. A self-hosted runner fee was announced, met a wall of objections, and was pulled back within a week. And a security roadmap arrived that will change how workflows pin dependencies and scope secrets over the next two to three quarters. Here is a grounded read of what happened, with sources, and an honest account of where Latchkey fits. Hosted runners got cheaper, and a new platform charge arrived On January 1, 2026, GitHub reduced GitHub-hosted runner prices by up to 39%, with the size of the cut depending on the machine type (larger runners saw the larger relative reductions), per GitHub's own changelog ( github.blog ). In concrete terms, community reporting put the Linux 2-core rate moving from $0.008 to $0.006 per minute and the Windows 2-core rate from $0.016 to $0.010 per minute ( samexpert.com ). Alongside the cuts, GitHub introduced a $0.002 per-minute Actions cloud platform charge that applies to all Actions workflows. For GitHub-hosted runners, that charge is already bundled into the reduced meter price, so it is not a separate line item there ( github.com ). Two things stayed the same and are worth repeating, because they get lost in the noise: standard runner usage on public repositories remains free, and GitHub Enterprise Server pricing is unaffected ( github.com ). GitHub framed the net effect as small for most accounts: it stated that 96% of customers would see no change to their bill, and that of the 4% affected, 85% would see costs decrease while the remaining 15% faced a median increase of roughly $13 ( github.com ). That is a reassuring headline. It is also a reminder that the bill depends entirely on your own mix of runner sizes and minutes, which is exactly the thi

Two forces are pulling on delivery pipelines this year. Code is arriving faster than ever, and the cost of running the pipelines that ship it has been unusually unsettled. Let us look at both, honestly, and then talk about where reliability work fits. Pricing was a moving target, and it still is On December 16, 2025, GitHub announced a simpler Actions pricing model that included a new $0.002 per minute "cloud platform charge." The plan was for that charge to reach self-hosted runner usage in private repositories on March 1, 2026 ( GitHub Changelog ). The reaction was strong enough that GitHub reversed the self-hosted portion within days. As GitHub put it, they "missed the mark with this change by not including more of you in our planning," and postponed the self-hosted charge to re-evaluate the approach ( GitHub Changelog ). Postponed is not cancelled, so if you run self-hosted runners in private repos, this is worth watching rather than filing away. GitHub's own framing was that the change would touch a small slice of accounts: it reported that 96% of customers would see no change to their bill, and that of the 4% affected, most would actually see their Actions bill decrease ( GitHub Changelog ). Even so, the principle of paying a per-minute fee for software running on hardware you already own was the sticking point for many teams, and the reversal followed quickly. The other half of the announcement did take effect. On January 1, 2026, GitHub reduced the price of GitHub-hosted runners by up to 39%, depending on the machine type, while leaving free minute quotas unchanged ( GitHub Changelog ). GitHub pointed teams to its runner pricing docs and calculator for the exact per-machine rates rather than publishing a single headline number ( GitHub Changelog ). That "up to" is doing real work in the sentence: the reduction depends on which machines you actually use, so the only way to know your number is to look at your own usage mix. The practical takeaway: the ground u

This project started with a simple goal: run Kubernetes without keeping an EKS cluster online every day. In I Wanted Kubernetes Without an Always-On EKS Bill , I built an always-on k3s lab on my home server and proved that I could deploy, update, and roll back an application. The rollback worked, but it exposed the next problem. Kubernetes restored Version 2 while the saved YAML still declared Version 3. I corrected the file manually, but the recovery depended on repairing the running cluster and its saved instructions separately. In The Rollback Worked. My Next Deploy Could Break It Again , I designed a safer path. The automated build process would test and publish an exact image, then stop at a Git pull request. Git would record the reviewed version. Argo CD, running inside Kubernetes, would make the cluster follow that record. Now I needed to prove that the design worked outside a diagram. I followed one release from source code to running Pods. Then I tested two opposite failures: The cluster was wrong while Git was correct. Git contained a bad setting while the cluster followed it correctly. Those experiments showed both the value and the limit of GitOps. Automation can make the cluster match Git, but it cannot decide whether the human-approved version in Git is a good one. CI Built the Release but Did Not Deploy It The GitHub Actions workflow—my continuous integration, or CI, worker—ran the application tests and checked the Kubernetes package before building anything. Its job was to prove and publish a release, not to change the cluster. After validation, Buildx created a Linux AMD64 image with the full source commit baked into /version : docker buildx build \ --platform linux/amd64 \ --build-arg "APP_VERSION= $GITHUB_SHA " \ --tag " $image_name : $GITHUB_SHA " \ --provenance = mode = max \ --sbom = true \ --push \ application After publishing the image, CI read its registry digest. A digest is the image's content fingerprint: if the image changes, the digest
