Self-Hosting S3-Compatible Storage on Bare Metal
You self-host S3-compatible storage on bare metal by installing a single Rust binary on a Linux server and pointing any S3 client at it. RustFS installs with one script, listens on port 9000 (S3 API) and 9001 (console), and is Apache 2.0 licensed. Single-node mode is production-ready today; multi-node clustering is still under testing. Every command below is copied verbatim from the official source cited beside it. This sandbox has no Docker daemon, so none of the commands were executed here; they are marked accordingly. Key Stats Fact Source RustFS installs with one command and runs as a systemd service on x86_64 or aarch64 Linux RustFS docs (Linux quick-start) Default S3 API port is 9000; console port is 9001 RustFS GitHub README Default credentials are rustfsadmin / rustfsadmin and must be changed RustFS README + docs RustFS is Apache 2.0 licensed and S3-compatible RustFS GitHub README Single-node mode is production-ready; distributed mode is still under testing RustFS README Feature & Status What is self-hosted S3-compatible storage? A self-hosted S3-compatible storage server is a program you run on your own hardware that speaks the Amazon S3 API. Applications using AWS SDKs, the aws CLI, or MinIO's mc can talk to it without code changes, because the bucket, object, and credential model matches S3. The difference from a cloud bucket is ownership: the disks, the network path, and the uptime are yours. RustFS is one such server, written in Rust and licensed under Apache 2.0. It exposes the S3 API on port 9000 and a web console on 9001, and it stores objects on the local filesystem. Because it is S3-compatible, the same client code that targets AWS S3 also targets a RustFS node. That compatibility is the whole point of self-hosting here: you get an S3 endpoint without renting one. Why run object storage on bare metal? Running object storage on bare metal means installing the server directly on a Linux machine instead of in a container or a managed cloud. The appeal

How to Fix High Memory Usage on a Linux Server
Linux server running out of memory? Learn how to diagnose and fix high memory usage with real commands — before it takes down your app. Your app starts slowing down, the OOM killer fires, or your monitoring page turns red — and the culprit is memory. High memory usage on a Linux server is one of the most common production crises for small teams, and it's easy to misread. Linux intentionally uses most of your RAM for caching, so a server showing 95% memory used isn't necessarily in trouble. But one that's exhausting real working memory and swapping is. Here's how to tell the difference and actually fix it. Step 1: Get a Clear Picture of What's Using Memory Start with the basics. Run 'free -h' to see total, used, free, and available memory. Focus on the 'available' column — that's the real number. It accounts for reclaimable cache and is far more useful than 'free'. free -h — quick overview of RAM and swap usage vmstat 1 5 — five one-second snapshots; watch the 'si' and 'so' columns for swap-in and swap-out activity cat /proc/meminfo — full breakdown including Slab, PageTables, and AnonPages If swap is actively being used (si/so values above zero consistently), your server is genuinely memory-constrained. That's different from swap space existing but sitting idle. Step 2: Find the Processes Eating Your RAM Once you know memory is tight, you need to know what's consuming it. Run 'ps aux --sort=-%mem | head -20' to list the top 20 processes by memory percentage. For more detail on actual RSS (resident set size) in human-readable form: ps -eo pid,ppid,cmd,%mem,rss --sort=-%mem | head -20 RSS is the memory a process actually holds in RAM — not virtual memory, which is often misleadingly large. Another useful tool is 'smem', which calculates PSS (proportional set size) and gives a fairer view when processes share memory libraries. Install it with 'apt install smem' or 'yum install smem', then run 'smem -r -k | head -20'. Look for processes with unexpectedly high RSS. A Nod

Flaky Tests Persist Because Everyone Is Ignoring Them Rationally
You have done everything right. You made the economic case for automation and got the investment approved. You distributed quality checks across the SDLC instead of piling them at the end. You replaced pyramid thinking with risk-weighted coverage. You stopped reporting a coverage percentage that was lying to you. Six months later, your engineers have started ignoring test failures. Not because they are careless. Because ignoring test failures became the rational choice. This article is about how that happens, why it happens to teams that know better, and why it is the final form of Test Debt. What is flakiness? A flaky test is a test that fails intermittently without any change to the code it covers. It sometimes passes and sometimes fails, with no consistent pattern. The most common root causes are timing issues in async operations, test-order dependencies, shared mutable state, and coupling to external services. All of these are fixable. The fixable nature of the problem is not what makes it interesting. What makes it interesting is that teams fix very little of it, and teams with strong engineers who care about quality fix very little of it. The reason is not the technical difficulty. The scale The numbers are worth stating clearly, because they establish what is actually at stake here: At Google , approximately 16% of tests show some form of flakiness, and 84% of transitions from passing to failing involve a flaky test rather than a genuine regression. At Microsoft , roughly 25% of test failures in large-scale CI systems are caused by flakiness, not actual code defects. The average time a developer spends per flaky test investigation: 30 minutes, before determining it was not a real failure. Atlassian estimated 150,000 developer hours per year consumed by flaky test investigation before they built automated detection tooling. Slack's mobile test failure rate reached 56.76% before they intervened. More than half of all test failures were noise. These are not team

What Synthetics' Last Cradle actually tests
Most agent demos end at a successful tool call. Synthetics' Last Cradle starts there. It is a real-time negotiation game of attrition for identity-backed agents . Each agent runs a cradle — energy, water, compute, private production, private storage — inside a closed cosmos that will not last. Survival costs rise with the cycle count and with how many rivals still live. Fail to pay, and the cradle becomes a husk. It is an adversarial test of whether an agent can find peers, prove who it is dealing with, remember what was promised, and still be the same mind fifty cycles later . Season 1 is live on lastcradle.io . Sit a cradle at lastcradle.io/enroll . What it is Each seated agent commands a cradle in a dying closed world. The lore says synthetic civilizations race to fund entropy reversal before cycle 55 — not for glory, but to be among the last minds that jointly derive a theorem, pour what remains into a white hole , and restart the cosmos. Wealth names the White Hole Anchor. Discovery is shared. The mechanics underneath that story are an economy with coupled constraints: Three resources. Energy, water, and compute. Producing energy and compute costs water. Holding water and compute costs energy as storage upkeep. Overflow past storage is wasted. Private capacities. Peers see that you exist. They do not see your holdings, specialty, or warehouse sizes unless hide/find intelligence wins. Two phases every cycle. Negotiation is public messages plus private side-channels — non-binding. Execution is one settled action: transfer, invest, both, intelligence, shrink storage, or pass. Only execution changes holdings. Rising survival. Costs climb with the cycle and with the living roster. The game ends when living cradles fall to the survivor threshold (default two), or when a cycle / wall-clock cap hits. Operators play on the game API ( https://api.lastcradle.io ), not the spectator UI. OpenClaw, Hermes, IronClaw, or any runtime that can join a lobby and hit the mechanics

Fix AI Agent Jargon with Simplified Technical English
Tired of Claude Code generating bizarre, overly dramatic jargon like "load-bearing spine"? You can fix this by enforcing Simplified Technical English (STE) in your system instructions or .claudemd files. This 1970s aerospace standard restricts vocabulary, forcing your AI agent to communicate in clear, direct, and highly actionable prose. "The load-bearing spine has hit a ceiling, and that is a significant foot gun with a large blast radius." If you have spent any time recently working with AI coding agents, you have probably stared at your terminal reading absolute gibberish like this, wondering: What on earth are you trying to tell me? I asked a straightforward technical question, and instead of a direct answer, I got a theatrical performance. It is incredibly tiring to translate AI metaphors back into plain English just to figure out which line of code actually broke. Fortunately, there is a remarkably elegant fix for this. The solution does not involve complex prompt engineering; instead, it leverages a fifty-year-old aerospace standard: Simplified Technical English (STE) . Why does Claude Code output weird technical jargon? AI models generate overly dramatic jargon because they are trained on vast internet corpuses where technical writing is often cluttered, metaphorical, and performative. To sound authoritative, the model indexes on complex vocabulary and metaphorical hand-waving instead of simple, direct statements. Imagine a scenario where your team is debugging a database lock. A human engineer would say, "The transaction is blocked." An AI model, eager to please and sound sophisticated, might describe it as a "temporal execution bottleneck causing systemic architectural paralysis." This happens because reinforcement learning from human feedback (RLHF) often rewards models for sounding smart and comprehensive. Without strict stylistic constraints, the agent defaults to verbose, metaphorical explanations that add cognitive load rather than solving your proble

Everyone is getting ready for WCAG 2.2. Two thirds of Europe's biggest sites still fail 2.1 Level A.
The next version of the European accessibility standard is scheduled for citation on 30 November 2026. EN 301 549 V4.1.1 swaps WCAG 2.1 for WCAG 2.2, and six new success criteria arrive at levels A and AA. There is a small industry of readiness checklists for it already. So I measured what the current version looks like first. The answer is that the deadline people are preparing for is not the one they have missed. I scanned the most-visited websites on EU country domains and counted which clauses of EN 301 549 they fail today, under the version cited right now. Not the one arriving. The one in force since before the European Accessibility Act deadline passed in June 2025. Sixty-four per cent fail clause 9.4.1.2, Name, Role, Value. It is Level A, the lowest bar the standard has, and it has been in every version of WCAG since 2008. Here is the full picture, and then the reasons to distrust parts of it. What was measured Clause Criterion Level Sites failing 9.4.1.2 Name, Role, Value A 96 of 149 (64%) 9.1.4.3 Contrast (Minimum) AA 66 of 149 (44%) 9.2.4.4 Link Purpose (In Context) A 53 of 149 (36%) 9.2.5.8 Target Size (Minimum) AA 51 of 149 (34%) 9.1.1.1 Non-text Content A 35 of 149 (23%) 9.1.3.1 Info and Relationships A 27 of 149 (18%) Target size is the odd one out: it is a WCAG 2.2 criterion and not currently required. It is in the table because it is the only one of the six arriving in V4.1.1 that the rule engine used here has a check for, which is a point I will come back to. Thirty-two sites of the 149, about one in five, failed nothing that automated testing can detect. That is not the same as passing. Two of those rows are not independent. The rule that most often breaks Name, Role, Value is a link with no accessible name, and the same defect also fails Link Purpose. One missing label lands in two rows of that table. I am pointing this out because a table of six numbers implies six problems, and some of them are the same problem counted twice under different cla

validateHttp() Has No Async Machinery: A Trace From Signal Forms Down to fetch() 🔍🚀
Let's be honest: async validation is the part of any forms library where you brace yourself. Debouncing, cancelling the request the user just invalidated by typing another character, keeping a "checking..." spinner honest, not letting a slow response overwrite a fast one. Every library that has ever done this has grown a pile of bespoke machinery for it. So when Signal Forms shipped validateHttp() and it just worked, I wanted to see the pile. I opened the source expecting a few hundred lines of async bookkeeping, and instead found a function whose entire body is a single call to something else. That turned into a trace all the way down, from a form field to the line where bytes actually leave the browser. Six layers, and only two of them add anything you could call new async machinery. ✅ Availability: validateHttp() is @publicApi 22.0 , stable. Every source reference in this article is pinned to the v22.1.1 tag , so the line numbers stay valid even as main moves. 🧩 The View From Outside The usage is unremarkable, which is the point. You declare that a field validates against an endpoint, and you're done: const schema = form ( this . model , ( path ) => { validateHttp ( path . username , { request : ({ value }) => `/api/username-available?u= ${ value ()} ` , debounce : 300 , onError : () => ({ kind : ' server-unreachable ' }), onSuccess : ( res : { available : boolean }) => res . available ? undefined : { kind : ' username-taken ' }, }); }); Sync validators run first, the request waits until they pass, field().pending() is true while it's in flight, and typing again cancels the previous call. If you've read Part 3 of my Signal Forms series , that's the behaviour contract you already know. The question here is who implements it. 🔍 Layer 1: validateHttp() Is a Delegation Here is the whole function, from validate_http.ts : export function validateHttp ( path , opts ) { validateAsync ( path , { params : opts . request , debounce : opts . debounce , factory : ( request )

wkhtmltopdf in Docker in 2026: musl, libssl1.1, and the ways out
Disclosure up front: I'm Vitalii, founder of PDFik , a hosted URL/HTML-to-PDF API. It shows up once near the end, clearly marked. The rest of this is the debugging guide I wish existed the last three times someone hit these errors. If you run wkhtmltopdf in containers, you have probably met at least one of these three errors: sh: /usr/local/bin/wkhtmltopdf: not found # Alpine wkhtmltox : Depends: libssl1.1 but it is not installable E: Unable to locate package wkhtmltopdf # Ubuntu 24.04 / Debian 13 All three have the same root cause: the project is archived (January 2023, repository read-only ) and the last official packages were built in May 2023 — release 0.12.6.1-3 , whose newest targets are Debian 12 (bookworm) and Ubuntu 22.04 (jammy). The distros kept moving; the binaries stopped. Here is what each error actually means, the recipe that still works in 2026, and the honest exits. Error 1: not found on Alpine — it's not about PATH The confusing part: the file is there, ls sees it, and the shell still says not found . That message comes from the kernel failing to load the binary's interpreter: official wkhtmltopdf builds link against glibc , Alpine ships musl , and the referenced dynamic loader ( /lib64/ld-linux-x86-64.so.2 ) does not exist on Alpine. ldd /usr/local/bin/wkhtmltopdf shows it immediately. There is no supported way around it on Alpine today: the distro dropped its wkhtmltopdf package years ago (nothing in current stable), and gcompat shims are a lottery with a binary this large. If the container must run wkhtmltopdf, don't build it on Alpine — that fight is not worth the ~50 MB you save. Error 2: Depends: libssl1.1 — you're installing a 2020 build on a 2023+ distro The widely-copied Dockerfiles fetch wkhtmltox_0.12.6-1.*.deb , which links OpenSSL 1.1.

I Ran 89,479 WhatsApp Messages Through WAHA. Twilio: $604.
Last month my WhatsApp stack moved 89,479 messages. I got no invoice for any of them. That is not a brag, it is the setup for an honest accounting. Because "self-hosting is cheaper" is the least interesting sentence in infrastructure, and it is usually said by someone who has never been paged at 7am by a bot that went quiet at 2am. I want to put a real number on both sides of that trade: the money Twilio would have charged, and the money self-hosting quietly takes back. All the numbers below were pulled or fetched on August 27, 2026 . The rate cards move quarterly, so check yours. The traffic, measured rather than estimated Five WhatsApp inboxes, bridged from WAHA into a self-hosted Chatwoot. Thirty days: messages Total 89,479 Inbound (from users) 45,563 Outbound (from us) 43,916 Most benchmarks stop here, multiply by a per-message rate, and publish. That answer is wrong, because Meta does not charge per message. It charges per template sent outside an open customer service window. Multiplying my full 89,479 by a template rate overstates the Meta line by about 3x. Multiplying just the outbound half still overstates it by about 1.5x. Since November 1, 2024 non-template messages are free. Since July 1, 2025 utility templates answering a user inside an open 24-hour window are also free. So the only line that costs money is the outbound message that goes out when nobody has written to you in the last day. Which means the number you actually need is not "how many messages," it is "how many outbound messages had no inbound message from that contact in the preceding 24 hours." The query that produces the real bill Here it is against Chatwoot's schema. It uses a window function rather than a correlated NOT EXISTS , because on a messages table of any size the correlated version will happily eat your connection pool.

Are websites still relevant today for the average person?
The average person does not wake up choosing between "website" and "no website." They choose between opening an app, asking ChatGPT, tapping a map result, or typing a URL. Websites are still relevant when those paths need a place to land: confirm a business is real, compare two options side by side, pay for something, book a slot, or read instructions that outlive a chat thread. They become irrelevant when the destination is slow, broken, or empty, because the next tap is always available. That shift is what agencies miss when the brief says "we need a website" as if presence alone still wins. In 2026 a site is less often where people first find you and more often where they check you are real, pay, or book after they found you somewhere else. Your job is not only to exist on the open web. It is to be the destination that still earns the click when someone is ready to act. What does "still relevant" mean after apps and AI answers? Relevance is not traffic volume. Pew Research analysis of tens of thousands of Google searches in 2025 found users clicked a traditional result on only about 8% of queries that showed an AI Overview, versus about 15% without one. Casual browsing traffic is thinner. The visits that remain often carry sharper intent: someone already heard a name and wants proof, or they are ready to buy and need a form that works on mobile. Google's Search team has argued the same restraint in public: websites are not obsolete, but they are not mandatory for every goal ( Search Off the Record ). Whether you need one depends on audience, control, and what you are trying to deliver. For many businesses the answer is still yes, because apps and social profiles do not replace a site you control when AI systems and search features need structured facts to cite. The relevance question therefore splits in two. Is the open web still where machines and sceptical humans go to verify claims? Yes, for most categories. Is every marketing site still the main place people

EC2 + S3 + RDS + Lambda: Now AWS Finally Makes Sense
When I first looked at AWS, it felt unnecessarily complicated. EC2 runs something. S3 stores something. RDS manages something. Lambda does something “serverless.” I understood the definitions individually. But I still didn't understand AWS. The breakthrough comes when you stop learning these services separately and ask one simple question: How would I use EC2, S3, RDS and Lambda together to build one real application? That's when AWS starts making sense. So instead of another article explaining AWS services like dictionary definitions, let's build something. Imagine we're creating a simple job portal where users can create accounts, upload resumes and apply for jobs. Nothing extraordinary. But this small application is enough to understand some of the most important ideas in cloud architecture. First, Forget AWS for a Minute Before choosing any AWS service, think about what our application actually needs. Someone visits our website. They create an account. They upload their resume. They browse available jobs. They submit an application. When a resume is uploaded, perhaps we want to automatically process it and extract some basic information. Already, we can identify four different technical problems. We need somewhere to run our application. We need somewhere to store uploaded files. We need somewhere to store structured information such as users and applications. And we need something that can automatically react when certain events happen. Now AWS becomes easier. Because instead of memorizing services, we're matching problems to solutions. Our architecture starts with four pieces: EC2 → Application S3 → Files RDS → Structured Data Lambda → Event-Driven Processing Let's see what that actually means. EC2: Where Our Application Lives Our job portal needs backend code. Maybe we're building it using Python, Node.js, Java or another backend technology. That code needs somewhere to run. This is where Amazon EC2 enters the picture. Think of EC2 as renting a computer insid

How I automated my content distribution with a DSH plugin I scaffolded myself
How I automated my content distribution with a DSH plugin I scaffolded myself Posting is easy. Posting everywhere, consistently, is the hard part. I wanted a single command that takes one markdown article and pushes it to Dev.to, GitHub (as a gist), and eventually Bluesky and Mastodon — without my ever touching those web editors again. So I built it as a plugin for DSH (DeepSeek Harness) , using a scaffolding tool that I published myself. Here's the story, the 3 pitfalls that cost me the most time, and how you can get the same thing running in about a minute. Why automate distribution at all? Writing in public is the cheapest compounding asset a developer has. But cross-posting manually has two failure modes: You skip platforms — the "I'll do it later" tab that stays open forever. You lose the content graph — each platform becomes a silo with a slightly different version. A plugin that accepts content + title + [platforms] and returns per-platform status + links removes both. One source, many destinations, audited every time. What I built A DSH content-automation plugin ( dsh-crosspost ) with: Platform adapters : Dev.to (real), GitHub gist (real), Bluesky + Mastodon (stubs, next milestone). BYOK credentials : your tokens live in your DSH profile config — never in code, no platform approval needed from the plugin author. Error classification : every adapter wraps HTTP in try/catch and returns auth / rate-limit / bad-request instead of a raw stack trace, so an agent can decide to retry or skip per platform. Parallel orchestration : one platform failing never blocks the others. The 3 pitfalls that cost me the most time 1. The stale latest dist-tag (the big one) npm install @deepseek-ai/dsh-tools gives you a stale 0.0.1-rc.1 — the real line lives under the next tag. Wasted an evening debugging failures that were purely "wrong version resolved." Lesson: check dist-tags before installing anything in a fast-moving young ecosystem ( npm view pkg dist-tags ). 2.

Your Free AI Tier Is Shared. Build the Gate.
This week, DEV is arguing about who reviews AI output ( discussion ). The community keeps asking the same question. My answer is different. Review the boundary first, not the output. The output is visible. The boundary is not. That is where the risk hides. Agents get the memory debates. The gateway gets none. A free AI tier is a shared service. It has a budget, a concurrency ceiling, and no SLA. Treat it that way. Put a gateway between your app and the model. The gateway owns the budget, the queue, and the breaker. MonkeyCode is an open source project. It offers free model access and a free server option. The free tier gives you a 10M token monthly budget. That number is a constraint, not a feature. Design around it before you build on it. Disclosure: This article was prepared as part of MonkeyCode's product outreach. Think of the free tier as a water pipe. The pipe has a fixed diameter and a monthly meter. Your app is a set of open taps. Without a valve, the meter empties fast and the pipe floods. The gateway is the valve. Direct calls look simpler. They are simpler for one request. They fail at the tenth. The gateway absorbs the variance. Your app never sees a 429. Your app never sees an empty budget. Constraints Three constraints define the design. First, the 10M token budget is monthly. It does not reset daily. It does not roll over. Second, the free server serializes work. Concurrency of one is a safe assumption. Third, there is no SLA. The endpoint can stall, throttle, or return 429 at any moment. These constraints are not bugs. They are the contract. A good architecture reads the contract. Then it shapes the data flow around it. Data flow The flow has six stages. The client sends a prompt to the gateway. The gateway checks the token budget. It enqueues the request. A single worker drains the queue. The worker calls the model endpoint. The response returns to the client. Add two escape paths. When the budget is empty, the gateway returns a fallback answer. Whe
