As expected, yesterday's WWDC keynote was mostly about AI. And also as expected, Apple tried to turn its late arrival into its sales pitch: it didn't rush into AI because it was taking its time to do things right. In this case, "right" means "with more privacy than anyone else." It's a good pitch - […]

Netflix engineer Casey Bleifer shares how to achieve rapid, automated code changes across a massive, diverse software fleet. She discusses building an event-driven orchestration platform using composable, Lego-like steps, and explains how Netflix utilizes automated canary validation, compliance checks, and a custom "confidence metric" to eliminate the long tail of manual engineering migrations.

In 2019, Alex Vindman testified during President Trump’s first impeachment trial–a decision that ended his military career. Now he wants to challenge the president from the halls of Congress.

The outspoken longevity scientist David Sinclair has been predicting that one day, you’ll go to the doctor and get a prescription that will make you 10 years younger. Now MIT Technology Review has learned that he has plans to launch human tests of an oral “reprogramming” drug as part of a $101 million competition organized…

Hey, welcome back. Last time we talked about missing parameterization in test scenarios. Today's mistake is similar in spirit. The test runs. The numbers look great. But what you've built isn't a load test. It's a hammer. ⚠️ The script works. The test is inhuman. Real users don't fire requests like a machine gun. They log in. They pause. They read. They click. They pause again. A typical user journey that takes 60 seconds in real life? Without think time, your script does it in just a few seconds. What this breaks Your throughput numbers are fiction. If users complete journeys 30x faster than reality, your RPS is inflated by 30x. You're not measuring capacity — you're measuring endurance under abuse. You stress the wrong things. Realistic concurrency surfaces real bottlenecks. A firehose of instant requests just overloads your connection pool and calls it a day. Production behaves nothing like your test. Because real users think. Your script didn't. 🛠 The fix Add randomized pauses between steps. Every major tool supports it: JMeter: Gaussian Random Timer, Uniform Random Timer etc. k6: sleep(Math.random() * 5 + 3) Gatling: pause(3.seconds, 8.seconds) Locust: time.sleep(random.uniform(3, 8)) 3–8 seconds between actions is a reasonable starting point. Check your analytics for what real sessions actually look like. Before your next run: Pauses between every major action? Randomized, not fixed? Does the timing feel human? If not — you're not testing load. You're testing collapse. Think time is one piece of the puzzle. But realistic load modeling goes deeper — it's about understanding how real users behave, how to translate that into a load profile, and how to design a test that actually reflects production. That's not something you patch with a timer. It's something you build from the ground up. If you want to understand the full system — from load model design to test execution to results that mean something — that's exactly what Performance Testing Fundamentals course

The startup is one of many entering the RV space, but it's banking on a hybrid power system that can go far beyond campsites.

Donut Lab's solid-state battery claims have been thoroughly debunked by Ryan Inis Hughes on his popular Ziroth YouTube channel. According to Hughes, Donut Lab has engaged in deliberate, calculated deception by claiming to have a solid-state battery ready for mass production. In reality, it's nothing more than a standard lithium-ion design. Hughes' investigation got an […]

If you’ve tried building AI applications, you often face a familiar engineering wall. It goes like...

From Scratch: How to Integrate Reasonix CLI into the HagiCode System This article shares the complete technical practice of integrating Reasonix CLI as a first-class Agent Provider into the HagiCode system, covering three-layer architecture design, key technical decisions, and frontend and backend implementation details. Background Reasonix CLI, as it happens, is a pretty interesting thing. It's an AI code assistant tool based on ACP (Agent Communication Protocol), providing powerful streaming and session management capabilities. Actually, in the HagiCode.Libs layer, we've already completed its underlying implementation. It's just that these components are still in an isolated state, like beautiful pearls that haven't been strung into a necklace. Users cannot use it through Hero profession selection, session execution paths, or monitoring panels, which is somewhat regrettable. The problem we face is: how to elevate Reasonix to the same level as Codex, Hermes, and other first-class Agent Providers, implementing complete backend routing and frontend display? This isn't simply a matter of registering an enum value. It requires building a complete chain from low-level abstraction to user interface. It's like building a house—you can't just lay a foundation and call it done. You have to build the walls and put up the roof. The challenge of this integration lies in the fact that Reasonix, as a local CLI tool, has its own personality and temperament. For example, it doesn't need a connection string—all parameters are configured by the user at runtime; it might not even be installed, requiring graceful degradation; it's compatible with anthropic series models, but also has its own ACP-specific parameters like effort, budget, and so on. It's like a person with their own unique way of handling things—you can't force it. After careful architectural design and multiple rounds of discussion, we finally adopted a clear three-layer architecture solution, successfully integrating R

Before this week, NFTs on Solana weren't new to me. I've previously worked with Programmable NFTs ( pNFTs ) and even built projects that integrate them. However, most of my experience was centered around the Metaplex ecosystem, so I tended to think about NFTs through that lens. What surprised me during this learning arc was discovering how much can be built directly with Token Extensions. By creating NFTs from the token level upward, I gained a much deeper understanding of the underlying primitives that make digital assets work on Solana. The Mental Model: What Is an NFT on Solana? As developers, we often interact with NFTs through SDKs , frameworks , and marketplace tooling. Those abstractions are useful, but they can hide what's actually happening on-chain. This week helped me simplify the model: An * NFT * is fundamentally a token mint configured with: A supply of one Zero decimals Metadata describing the asset Optional relationships to collections or groups Using Token Extensions, many of these capabilities can be attached directly to the token itself rather than relying on additional programs or infrastructure. That shift in perspective was one of the biggest takeaways from this challenge. What I Built Over the course of this arc, I created an NFT on Solana Devnet using Token Extensions and explored several capabilities that I had never implemented directly before. The process included: Creating a mint configured as an NFT Adding metadata using the Metadata Extension Minting a single token Creating a collection using the Group Extension Associating the NFT with the collection through the Member Extension Auditing the account structure and extension data on-chain Updating metadata after the NFT had already been created One of the most valuable parts of the exercise was inspecting the accounts directly instead of relying solely on SDK abstractions. For example: spl-token initialize-metadata \ <NFT_MINT> \ "My First NFT" \ "MNFT" \ https://example.com/metadata.jso

The 30-second version Anthropic shipped Claude Opus 4.8 a few hours ago. Every benchmark on the announcement page is up: SWE-bench Verified, GPQA, MATH-500, the agentic tool-use evals. The marketing copy reads as it always does — "our most capable model", "strongest coding performance", "better instruction following". If you have been around since 4.5, you know the shape of this announcement by heart now. The announcement skipped the only question that matters for teams running Claude in production: should you upgrade today, next week, or next month, and which of your workloads should stay on Opus 4.7 indefinitely? Anthropic does not write that part. They cannot — it is workload-dependent, and the answer for a code-review agent is different from the answer for a customer-facing chat product. This post is the decision tree I am applying to my own stack today. It is opinionated. Three of the workloads I run are staying on 4.7 until at least mid-July, and I will explain exactly why. Your mileage will vary, but the reasoning shape should transfer. What actually shipped in Opus 4.8 Let me anchor on the facts before the opinion. Opus 4.8 is the third release in the Opus 4.x family this year. The pattern across 4.6 (March), 4.7 (April), and 4.8 (today) has been roughly monthly. Each release has shipped a 2-4 point bump on SWE-bench Verified and a similar bump on the agentic evals. 4.8 follows the pattern: roughly 3 points on SWE-bench, about 2 points on the multi-step tool-use benchmark, and a more visible jump on the long-context retrieval evals — the 'needle in a haystack at 200K tokens' style tests. Three changes are worth pulling out of the announcement: Better long-context coherence . The 4.8 release notes specifically call out improved behavior on tasks that span more than 100K tokens of context. Concretely: less mid-context summarization, fewer instances of the model 'forgetting' early-context instructions, better citation of source material when retrieved chunks sp

Apple spending a big chunk of its WWDC keynote on parental controls was surprising for several reasons. But the biggest is that, despite all the airtime, it didn't announce much new beyond a redesigned interface. Almost all the features touted already exist or are upgrades to current options. Why Apple chose to do this isn't […]

Tools for Humanity, Sam Altman's identity verification company, is reportedly struggling to generate revenue and will downsize its staff.

When Apple put child safety front and center at WWDC on Monday, its stated goal was helping parents fine-tune their kids' online experiences and avoid excessive screen time. But amid a global debate over internet regulation, its latest updates also looked like a defensive move in a brewing fight against Meta and other app developers. […]

OpenAI on Monday checked off a preliminary step in the IPO race that it and rival Anthropic have been competing in for the better part of a year: The company announced it has confidentially submitted a Form S-1 with the US Securities and Exchange Commission, following Anthropic's decision to do the same on June 1st.
