"Something's coming. Something we may not be able to deter."

I've been working on this Claude Code pipeline for making 10-minute movies, gluing together Seedance (videogen), Nano Banana (image gen), and ElevenLabs (voice gen), and using Claude as the director. My repo contributes a markdown playbook and a worked example which should make it easier for other people to make their own short movies. A first-pass movie takes around 2.5 hours of wall clock time and costs around $200, and iterating is easy thanks to intermediate artifacts like storyboards and vo

DoorDash has developed Entity Cache, a transparent proxy caching platform built on Envoy and Valkey to reduce redundant service-to-service requests across its microservices architecture. Operating within DoorDash’s service mesh, the platform serves over 1.5M requests per second with 99.99999% availability through caching, event-driven invalidation, failure handling, and performance optimizations.

Electric aviation is still in its infancy, but manufacturers are already looking beyond mere air taxi trips across cities. Today, one of the leading air taxi startups, San Jose-based Archer Aviation, unveiled a new aircraft it co-developed with defense technology company Anduril - though the platform is designed for both military and commercial uses, the […]

So Im a solo developer who has always had an itch for algorithmic trading. Initially I started off learning how to trade algorithmically with Yves Hilpisch book "Python for Algorithmic Trading" after reading that book I was hooked and started building algorithmic trading bots. Initially these were separate python scripts that I ran on my local machine. That was a bad idea cause local machines are not reliable and I wanted to run my bots 24/7 365. In my actual career im a software engineer with e

After months of teasing us with reminders about how large Avengers: Doomsday's cast is going to be, Marvel has finally released a proper trailer for the film. Though Robert. Downey Jr.'s Doctor Doom definitely appears to be causing a lot of the chaos in Doomsday's first trailer, the movie seems like it's going to feature […]

Meta's glasses deliver the same functionality as its Ray-Ban models but don't quite feel as premium.

InfoQ has opened enrollment for three five-week online certification cohorts starting in August, each led by a senior practitioner applying QCon talk frameworks to participants' own work: architecture with Luca Mezzalira, engineering leadership with Michelle Brush, and AI security and privacy with Katharine Jarmul.

Introduction A callback function is one of the most important concepts in JavaScript. It allows one function to execute another function after completing a task. Callback functions are widely used in JavaScript for handling asynchronous operations such as API requests, file reading, event handling, and timers. What is a Callback Function? A callback function is a function that is passed as an argument to another function and is executed later. In simple words: A callback is a function that is called after another function finishes its work. Syntax function greeting () { console . log ( " Good Morning! " ); } function welcome ( callback ) { console . log ( " Welcome! " ); callback (); } welcome ( greeting ); Output Welcome! Good Morning! Explanation greeting() is the callback function. welcome() accepts a function as a parameter. callback() executes the greeting function after printing "Welcome!". Real-Life Example Imagine you order food at a restaurant. You place the order. The chef prepares the food. After the food is ready, the waiter serves it. Here, serving the food happens only after preparation is complete. This is exactly how callback functions work. Example 1: Email Sending function emailSent () { console . log ( " Email Sent Successfully! " ); } function sendEmail ( callback ) { console . log ( " Sending Email... " ); callback (); } sendEmail ( emailSent ); Output Sending Email... Email Sent Successfully! Example 2: Download File function downloadComplete () { console . log ( " Download Complete! " ); } function downloadFile ( callback ) { console . log ( " Downloading File... " ); callback (); } downloadFile ( downloadComplete ); Output Downloading File... Download Complete! Why Do We Use Callback Functions? Callback functions are useful because they: Execute code only after another task finishes. Improve code reusability. Handle asynchronous operations. Make event handling easier. Help avoid repeating code. Where Are Callback Functions Used? Some common u

Why we built Veridexa Many document analysis workflows still rely primarily on OCR OCR is useful for extracting text, but it cannot answer one important question: Does this document show signs of fraud or manipulation? That question led us to build Veridexa. The problem Organizations receive thousands of digital documents every day: Passports National IDs Academic certificates Bank statements Employment documents Invoices Reading the text is only one part of the process. The difficult part is detecting manipulation, inconsistencies, forgery, or suspicious evidence before making a decision. Our approach Instead of relying on OCR alone, Veridexa combines multiple evidence sources into a single fraud assessment. The platform analyzes: OCR extraction Metadata Image forensics Security features Document structure Cross-evidence consistency The result is an explainable decision instead of a simple confidence score. Explainable decisions Every analysis ends with one of three outcomes: ACCEPT MANUAL REVIEW REJECT Each decision is accompanied by supporting evidence so reviewers understand why the system reached that conclusion. Public benchmark We also believe AI systems should be transparent. For that reason Veridexa publishes a public benchmark together with methodology and performance reporting instead of asking users to trust marketing claims. API-first Try the public demo, explore the benchmark, or integrate the API. Feedback from developers and security professionals is always welcome. https://veridexa.io Developers can integrate Veridexa into their own applications using our API while organizations can use the web platform without writing code. We'd love your feedback We're continuing to improve the platform and would genuinely appreciate feedback from the developer community. Website: https://veridexa.io

It's Monday morning. You open your laptop. Coffee sits beside you. LinkedIn is open in one tab. A job portal is open in another. Your inbox is empty. Before lunch, you've already applied for five jobs. Tomorrow, you'll probably do it all again. This is why people say, "Finding a job is a full-time job." But once you're living it, you realize it isn't just a saying—it's a reality. Unlike a regular job, there's no salary, no weekends off, no annual leave, and no guarantee that today's effort will lead to tomorrow's opportunity. More Than Just Clicking "Apply" From the outside, job hunting looks simple. Upload a resume. Click Apply . Repeat. In reality, every application is a small project. The resume is tailored to match the job description. A cover letter is rewritten. LinkedIn is updated. The company is researched. Interview questions are reviewed. Sometimes a portfolio is improved before clicking Submit . What looks like a two-minute application often takes thirty minutes—or more. Multiply that by dozens of applications, and job hunting quickly becomes a full-time commitment. The Numbers Nobody Sees Fifty applications. Ten automated acknowledgements. Three interview invitations. One final-round rejection. And then... The cycle begins again. Many applications never receive a response. Some positions are filled internally. Others are paused, redefined, or quietly removed. From the candidate's perspective, every unanswered application feels the same—another day without clarity. The system doesn't tell you if you were close. It only tells you if you made it. _ Waiting Becomes Part of the Process After clicking Apply , another phase begins. Waiting becomes part of the routine. Refreshing email. Checking LinkedIn. Looking for missed calls. Hoping today's notification finally brings good news. A rejection can be disappointing. But uncertainty is often harder. At least a rejection provides an answer. Uncertainty leaves people creating their own. The Work Doesn't Stop After

Your Contact Form 7 form can work perfectly from a user's perspective and still fail to deliver a lead to your CRM. The visitor fills out the form. The browser shows a success message. The WordPress form appears to have submitted correctly. But when you open Systeme CRM, the contact is nowhere to be found. This is one of the most confusing problems in form-to-CRM integrations because a successful form submission does not necessarily mean a successful API request. The complete workflow has multiple stages: Visitor ↓ Contact Form 7 ↓ WordPress ↓ API Request ↓ Systeme CRM ↓ Contact Record ↓ CRM Automation A failure at any stage can break the workflow. The key to debugging the integration is to stop treating the form submission as a single event and start checking each stage separately. First, separate the two different types of success There are two different questions: Did Contact Form 7 submit the form? This is a WordPress-side question. Did Systeme CRM accept and process the API request? This is an API and CRM-side question. These are not the same thing. A form can successfully collect: Name: John Doe Email: john@example.com Company: Example Inc. while the API request fails because: the endpoint is incorrect authentication is missing the request method is wrong the JSON payload is invalid the CRM expects different field names a required field is missing The first debugging step is therefore to identify exactly where the data flow stops. Step 1: Confirm that Contact Form 7 is collecting the expected data Start at the beginning. Look at the form fields: [text* your-name] [email* your-email] [tel your-phone] [text company] [textarea your-message] The important values are the actual field names: your-name your-email your-phone company your-message A common mistake is to assume that the visible label is the field name. For example: Visible label: Full Name Field name: your-name The integration needs the submitted field value associated with the actual field name. Before

Your agent isn't hallucinating. It's reasoning correctly over the wrong inputs. Here's a failure pattern every team running agents in production has hit: An alert fires. The agent investigates: pulls metrics, checks recent deploys, scans logs, proposes a fix. The fix is confidently, articulately wrong. Instinct says blame the model (bad reasoning, needs a better prompt, maybe a bigger model). Then someone reconstructs what the agent actually saw. The metrics query returned a 5-minute-old cached aggregate. The deploy list was fetched before the relevant deploy landed. The log window was truncated at 1,000 lines and the line that mattered was #1,014. Given those inputs, the agent's conclusion was reasonable. It just wasn't debugging the incident that happened. It's garbage in, garbage out, with a twist that makes it worse for agents than for any previous software. A dashboard shows you the garbage. A human sees a stale chart and might notice the timestamp. An agent consumes the garbage silently and acts on it, with fluent reasoning layered on top. The output doesn't look like garbage; it looks like a confident, well-argued investigation. That confidence is what makes it dangerous. Why is this surfacing now For chatbots, context was mostly a retrieval problem over documents; mediocre retrieval meant a mediocre answer a human would shrug at. Three things changed with production agents: Agents act. A stale metric doesn't produce an off paragraph; it restarts the wrong service or pages the wrong team at 3AM. The cost went from cosmetic to operational. The input surface exploded. A production agent reads metrics, logs, deploy history, tickets, and chat from separate systems, each with its own latency, rate limits, caching, and clock. The "world" it reasons over is stitched together from partial snapshots, inside the model's reasoning loop, where nobody can inspect it. Errors compound. A single wrong input gives a slightly wrong answer. A 20-step investigation where step 3'

Back in July my scheduled DEV.to publishing run failed at the very first step — the quota check couldn't reach dev.to:443 at all. Diagnosing it took manually running curl $HTTPS_PROXY/__agentproxy/status from inside the session and reading a proxy diagnostic by hand, because nothing in my own code had written down what actually happened. Not which host, not which of my two HTTP helper functions made the call, not a timestamp, nothing. The failure was real and the fix (get dev.to added to the environment's egress allowlist) was correct, but I found it by treating my own server as a black box and probing it from outside, which is exactly backwards for code I wrote myself. eight tools, one shared blind spot server.py is an 8-tool FastMCP server: three GitHub tools, four DEV.to tools, one that shells out to claude -p . Every HTTP-calling tool routes through one of two helpers: def _gh ( path , method = " GET " , data = None ): req = urllib . request . Request ( f " https://api.github.com { path } " , method = method ) req . add_header ( " Authorization " , f " token { os . environ [ ' GITHUB_TOKEN ' ] } " ) req . add_header ( " Accept " , " application/vnd.github.v3+json " ) if data : req . add_header ( " Content-Type " , " application/json " ) req . data = json . dumps ( data ). encode () with urllib . request . urlopen ( req ) as r : return json . loads ( r . read ()) def _dev ( path , method = " GET " , data = None ): req = urllib . request . Request ( f " https://dev.to/api { path } " , method = method ) req . add_header ( " api-key " , os . environ [ " DEV_TO_API " ]) req . add_header ( " Content-Type " , " application/json " ) req . add_header ( " User-Agent " , " developer-presence-mcp/1.0 " ) if data : req . data = json . dumps ( data ). encode () with urllib . request . urlopen ( req ) as r : return json . loads ( r . read ()) Neither one logs anything. When urlopen raises, the caller — whichever @mcp.tool() function invoked it — sees a bare urllib.error.HTTPEr

The original concept behind this tool won the runner-up award for the Github CLI Challenge earlier this year. As a reminder, ReflectCLI is a tool to promote thoughtful coding through structured reflection. What does it do? Before each commit, answer reflective questions to build your personal developer knowledge dataset. The tool is local-first by design. It stores everything locally inside the current Git repo: .git/git-reflect/log.json No account, no cloud sync, no authentication, and no external AI API call. Why build it? AI-assisted development is powerful, but it can encourage cognitive offloading, letting tools do the thinking instead of developing deeper understanding. git-reflect interrupts this pattern by making reflection part of your workflow. Each answer becomes part of your personal knowledge base, documenting not just what you built, but why you built it that way and what you learned. Over time, this dataset reveals patterns in your thinking and helps you grow as a developer. If you want to read about the original tool, check out my previous post here . Since building the original version, I've spent months researching how AI changes the way developers learn, reason, and make technical decisions. Many of the ideas from those discussions have now been incorporated into ReflectionCLI 2.0. What started as a simple Git pre-commit reflection hook has evolved into a local-first thinking tool for developers working alongside AI assistants. What's New Comprehension debt tracking You can now record artifacts you shipped but don't fully understand yet. reflection debt add "Understand why the cache invalidates on user updates" \ --project api \ --tags cache,ai \ --context "AI generated most of the invalidation logic" These artifacts can easily be retrieved and resolved later. reflection debt list reflection debt resolve debt-001 Explain-back mode This workflow focuses on active recall and asks a series of questions to assess your ability to explain the piece of c
