When asked about product-market fit, Spiegel said he believes mass-market consumer adoption won't occur until the end of the decade.

Alibaba officially launched Qwen3.8-Max on Monday, marking the debut of its most substantial artificial intelligence model. This new open-weight release aims at enterprise sectors, specifically targeting software engineering and complex reasoning. It represents a significant expansion of the company’s existing portfolio of digital tools for large-scale business operations. Technical architecture and performance benchmarks The Qwen3.8-Max model utilizes a mixture-of-experts (MoE) design, featuring a total of 2.4 trillion parameters. However, the system only activates approximately 95 billion of those parameters during any single inference cycle. This approach balances high-level processing power with the need for operational speed. Alibaba plans to make the open-weight versions of this technology available to the public through its cloud-based studio platform starting next week. Company representatives stated that this new architecture ranks among the most capable systems currently in existence. They position it as a direct competitor to the most advanced frontier models available globally. Internal data suggests the performance levels are trailing only the very top tier of experimental AI systems. This move signals a clear intent to capture market share from established western technology firms. Competitive testing and industry analysis To prove its capabilities, Alibaba released internal data comparing Qwen3.8-Max against top models from Anthropic and OpenAI. The tests focused heavily on coding benchmarks such as SWE-bench Pro. According to the company, their new model held its own against Claude Opus 4.8 and GPT-5.6 Sol. They utilized the specific coding frameworks recommended by each competitor to ensure a fair and rigorous comparison during the evaluation process. Industry analysts have noted that the gap between proprietary and open-weight models is closing rapidly. While proprietary leaders still hold certain advantages, the rise of open-weight alternatives pr

Somewhere on your feed right now, someone is bragging about the app they built in a weekend, no engineering background, no team, just a prompt and a Saturday. The post always ends the same way. Look what I built without needing any of you. Anyone can build software now. That is the whole pitch, repeated in a hundred different captions this month alone. Here is what that post never shows you. The part where someone checks it. Not "does it run." Checks it. Someone who did not write it, looking for the version of it that fails, the input nobody thought to try, the assumption that was wrong in a way the builder was structurally the worst person to catch, because they were too close to their own idea to see the hole in it. That someone is not optional. It is the actual job. None of this is theoretical. A notification icon that, instead of opening a panel, closes the entire page and drops me back on an empty tab. A video call that disconnects mid sentence for no visible reason. A video that plays with the sound simply gone, until I restart it. I do not have a chart proving reliability across the industry is getting worse. What I have is a pattern I keep running into, on products built by some of the most resourced engineering organizations on earth. Why software engineering has more than one person in the room A developer writes the code. A reviewer reads it before it merges. QA tries to break it on purpose. A manager decides if it is actually ready, or just finished. None of these roles exist because engineers do not trust themselves. They exist because a single person, however good, cannot see their own blind spots. That is not a flaw in the person. It is a fact about how blind spots work. Ten sets of eyes exist so that the eleventh mistake gets caught before a million people hit it. We have already watched what happens when that layer disappears, and we did not need AI to run the experiment. We ran it with the spreadsheet. The spreadsheet already showed us the cost of

A practical calculator for turning an upload limit into a video bitrate, with enough margin for audio and container overhead. “Make this video smaller” is an open-ended request. “Make this three-minute video fit under 10 MB” is an engineering constraint. The second version sounds more precise, but a quality slider alone cannot solve it. A quality setting tells an encoder how aggressively to preserve detail. It does not directly tell us how many bytes the final file may contain. If the destination has a hard upload limit, the useful starting point is a bit budget. This article builds that calculation in TypeScript, then looks at the assumptions that make the answer less exact than the formula first appears. File Size Is Bitrate Multiplied by Time A video file contains several streams plus a container. For a simple MP4, the largest pieces are usually: the video stream; the audio stream; container metadata and indexing overhead. If we ignore overhead for a moment, the relationship is straightforward: file size in bits = total bitrate in bits per second × duration in seconds Rearranging it gives us the total bitrate available for a target size: total bitrate = target size in bits / duration in seconds That total must cover both video and audio. The approximate video budget is therefore: video bitrate = total bitrate - audio bitrate - overhead allowance The result is not a promise. It is a budget that an encoder can aim at. Be Explicit About MB and MiB Before writing code, decide what “10 MB” means. Storage vendors and many web services use decimal megabytes: 1 MB = 1,000,000 bytes Operating systems and developer tools often display binary mebibytes: 1 MiB = 1,048,576 bytes The difference is about 4.9%. That is large enough to turn a file that looks safe locally into a rejected upload. For a hard external limit, I prefer to calculate with decimal MB and keep an additional safety margin. For an internal tool where the unit is clearly MiB, I make that choice explicit in th

Git is the ultimate tool for developers. Yet, branching strategies still confuse many of us. Commands like merge, rebase, and cherry-pick manipulate your commit history in completely different ways. If you just guess what they do, you risk ruining your team's shared history or losing track of your changes. The easiest way to understand Git is to visualize it. Let us look at exactly what happens to your Git graph when you run these three critical commands. 🏗️ Starting Point: Our Example Repository Imagine we have a standard repository. We branched off the main branch from commit B to work on a new feature in a feature branch. While we worked on our feature, someone else pushed commit C and D to main. Here is what our history looks like right now: C --- D [main] / A --- B \ E --- F [feature] main has two new commits: C and D. feature has two new commits: E and F. 🔀 1. Git Merge (The Safe Record Keeper) When you merge main into your feature branch (or vice versa), Git creates a special, brand-new commit called a merge commit. git checkout feature git merge main The Visual Graph After Merge: C ------- D ------ [main] / \ A --- B \ \ v E --- F --- G [feature] What happened under the hood? Git looked at the common ancestor (B), took the history of main (C and D), took the history of feature (E and F), and combined them. Commit G is the merge commit. It has two parent commits: F and D. Pros: 100% non-destructive. It preserves the exact historical timeline of when things actually happened. Cons: Your Git graph can quickly become a messy "train track" web if you have many developers merging constantly. 🚀 2. Git Rebase (The Clean History Rewriter) Rebase takes all the commits from your current branch, lifts them up, and replants them on top of the very last commit of the target branch. git checkout feature git rebase main The Visual Graph After Rebase: C --- D [main] / \ A --- B E' --- F' [feature] What happened under the hood? Git temporarily blew away commits E and F. It ca

Hello. No idea if anyone's going to read this, but writing it feels like I've done something, so here we go. And maybe it helps someone. For the past few years, I've been building a piece of software in Unity. It has actual users, somehow. My role was everything: founder, product owner, and whatever else needed doing. Development, UI, the website, the content. That's startup life. I'm good at learning fast and shipping, so it worked.(of course not all of it... I'm not trying to take all the credit for others' work Im just saying what I did) But I never came into this as a leading developer, so updating the product became kinda frustrating. Moreover, graphics are central to this product, and even with HDRP, Unity wasn't getting me where I wanted. I know my way around C#. C++, not so much. With Unreal, I've learned the basic UI and not much else. BuT~ You study, you keep going, and things tend to work out. So wish me luck I'll reveal what the product is once the switch to Unreal succeeds I'll take some courses. I don't care if it's in Korean or English. I'll make it work. Time passes either way, we get older, we all die anyway. So let me just learn and build what I want to build. I'm writing this to leave a record of what I learn and what I try.

The global memory chip shortage appears to be affecting the availability of Apple’s most popular Mac.

Most of the engineers consider documentation as an after-thought; a README on a finished system written in the final 20 minutes before a PR gets merged. That's the wrong way to do this relationship. Documentation is not a description of architecture. It is part of the architecture, and marking it as separate is the cause of so many rotting systems, which still pass all tests. The compiler doesn't care, your team does It could be a consistent codebase and yet it be undocumented garbage from the point of view of anybody who didn't write it. Only one sort of correctness is enforced by the compiler (or interpreter): does this code perform the operation that the instructions say it performs. It doesn't weigh in on why a specific table contains a deleted_at column, versus a hard delete, or why a service tries 3 times with exponential back-off, versus 5 times with a fixed interval. Those decisions include constraints that are not apparent in the diff, regulatory, historical, or performance. If these are only in the mind of the programmer who wrote them, the actual architecture is partially undocumented, and these constraints will be breached as soon as someone else messes with the code when it is under a tight deadline. Architecture is not only the shape of your services and schemas, it's the set of decisions and constraints that shape stayed within. Undocumented constraints are like walls that we don't see, or know about. They are walked through without anyone knowing they exist, and one of the assumed conditions is broken at a time. Documentation as a design artifact, not a report Good documentation should be done prior to and/or in the midst of implementation, not after. When writing a design doc that explicitly states the problem, the options you considered, the one you selected, and the tradeoffs you made, you are actually doing real design work, you are making mistakes in your thinking process that would only become apparent during production. There have been more ti

When I published v2.0.0 , I thought the hard part was over. The CLI could turn Claude artifacts into native Windows applications in a single command. It worked on my machine, the demos looked great, and I was excited to share it. Then people started using it. That's when I realized the difference between building software and shipping software . The bugs only users can find Most of the problems weren't visible in a five-minute demo. Some applications worked perfectly. Others silently lost all of their data after being closed. Some builds succeeded exactly once. The second build failed unless the runtime cache was manually deleted. Everything looked correct... until someone actually tried using it. The rabbit hole What I thought would be a quick patch became a deep dive into things I'd never touched before. Over the course of v3 I ended up learning far more than I expected: Git branching and release workflows Semantic versioning GitHub Actions npm packaging npm pack Runtime integrity verification SHA-256 checksums Neutralino runtime management JavaScript debugging Integration testing None of those were part of the original project idea. Persistent storage finally works This was the biggest challenge. Artifacts using localStorage behaved differently depending on where they were running. Inside Claude everything worked. Inside the generated desktop application... not always. Tracking this down took far longer than writing the original feature. The result is that applications now persist their data correctly across launches without requiring any code changes. If your artifact uses localStorage , it should simply work. Runtime improvements The runtime layer also received a major overhaul. Version 3 now handles: automatic runtime downloads integrity verification cache recovery consecutive builds without manual cleanup Those aren't exciting features to demo, but they're exactly the kinds of improvements that make a tool feel dependable. Better testing I also spent a lot mo

Every automated system receives a particular shape of the world. That shape is expressed through records, documents, events, exceptions, and missing values. If the designers have not identified those forms—and the ways they can become malformed—the machine inherits their ignorance and reproduces it at scale. The question is not simply whether the AI failed. The useful question is whether the human-built system knew what success meant, knew the shape of its data, and knew how to recognize when it was wrong. Start with the shape of the data Before selecting a model, draw the workflow as a sequence of data transformations. What enters each stage? In what form and from what source? Which values are valid, absent, duplicated, stale, delayed, or contradictory? How will each violation be detected? What must the workflow do next? Each data shape needs a corresponding failure model. An unknown here is not merely uncertainty for the machine; it is a measurement failure in the organization. The remedy is to collect the missing data or explicitly design for its absence. Otherwise, the system is being asked to operate in a world its designers have not described. Stabilize the deliverable A system cannot be stabilized around a target that continues to move. The deliverable must be more than an aspiration written in a prompt. It should be expressed as observable conditions and anchored to a representative corpus: examples that are acceptable; examples that are unacceptable; examples that are genuinely ambiguous. Human reviewers should first demonstrate that they can apply those distinctions consistently. If they cannot agree on what success looks like, the model is not being measured against a specification. It is being measured against human disagreement disguised as one. The model is not the system Only then does it become meaningful to place an AI model inside the workflow. The model is one transformation among many: Input → validation → retrieval → normalization → model infere

Three bugs we found and fixed in our own pipeline this week Journeymen grades developer work against GitHub's server-side history. That only means something if the grading pipeline itself is reliable — so here's the honest engineering update, not the highlight reel. 1. Silent progress loss on connect-repo analysis runs A connect-repo analysis run could sit in processing status with no visibility into what stage it was actually at, or whether it had stalled. From a dev's dashboard, a slow run and a stuck run looked identical. We added explicit progress-stage tracking so a stuck run is visibly stuck, not silently pending. 2. A background worker timing out without a clear signal The Lambda-based worker handling asynchronous analysis jobs was hitting its timeout under certain repo sizes, and the failure mode wasn't obvious from the outside — a run would just never complete. We root-caused the timeout and fixed the underlying slow path. 3. Dead-letter queue with no observability Jobs that failed enough times to land in the SQS dead-letter queue were, until this week, invisible — no alerting, no in-product surfacing. We wired up observability so a DLQ arrival is now a visible signal instead of a silent dead end. Why post about our own bugs The entire pitch of Journeymen is "don't trust the self-reported version, trust the verified one." That standard has to apply to us too. All three issues: found, fixed, and shipped this week. journeymen.in

"A Heap doesn't stay useful because everything is sorted. It stays useful because every parent follows one simple rule." In the previous article, we learned that a Heap is built for continuous decision-making. Whether it's assigning the nearest driver, scheduling the next process, or selecting the most urgent support ticket, the system always needs one thing: The next best candidate But that raises an interesting question. How can a Heap always know the best candidate without sorting everything? The answer lies in one simple rule: The Heap Property. This single rule is what gives a Heap its power. The Biggest Misconception About Heaps Many beginners imagine a Heap like this. 100 95 90 82 76 64 51 Everything perfectly sorted. It feels logical. If the largest element should always come first, shouldn't every element be arranged in order? Surprisingly, no. A Heap solves a much smaller problem. It only guarantees that the best element is always easy to reach . Everything else only needs to follow one simple relationship. Imagine a Company Hierarchy Think about the structure of a company. CEO ↓ Engineering Director ↓ Engineering Manager ↓ Software Engineer The CEO doesn't directly manage every employee. Instead, each manager is responsible only for the people immediately below them. The entire organization works because every manager fulfills their local responsibility. A Heap works in a very similar way. Every node only needs to maintain the correct relationship with its immediate children. It doesn't need to know about every other node in the structure. The Heap Property Let's look at a Max Heap. 100 / \ 90 80 / \ / \ 75 60 70 50 Notice the pattern. Every parent has a value greater than or equal to its children. That's the Heap Property. Parent ≥ Children That's it. There is no rule saying that every node must be greater than every other node in the Heap. Only the parent-child relationship matters. What About a Min Heap? Some systems want the smallest value first. For

"A HashMap helps you find what you already know. A Heap helps you decide what should happen next." In the previous article, we discovered that not every software problem is about finding a specific object. Sometimes, the system already knows exactly what it's looking for. Find User ID = 1024 ↓ Return User Other times, the system doesn't know the answer in advance. Instead, it has to repeatedly answer questions like: Which task should run next? Which driver should be assigned? Which customer should be served first? Which alert is the most critical? These are fundamentally different problems. Instead of retrieving an object, the system is making a decision. This is where a Heap comes in. A Heap Is Built for Decisions, Not Searches Imagine you're managing a hospital emergency room. Patients keep arriving throughout the day. Patient A Minor Injury Patient B Heart Attack Patient C Broken Arm Patient D High Fever Should doctors treat patients in the order they arrived? Probably not. Instead, they ask one question. Who needs treatment first? Notice something important. The hospital isn't searching for a particular patient. It's choosing the highest-priority patient. A Heap is designed for exactly this kind of problem. A Different Way of Thinking When beginners hear "data structure," they often think about storing data. Experienced engineers think differently. They ask: "What operation does my system perform repeatedly?" If the answer is: Find User Find Order Find Product that's a lookup problem. But if the answer is: Choose Highest Priority Choose Nearest Driver Choose Earliest Deadline that's a decision problem. A Heap is optimized for continuous decision-making. What Exactly Is a Heap? A Heap is a data structure that keeps the most important element immediately available. Depending on the system, "most important" can mean different things. For example: Highest priority Lowest cost Earliest deadline Highest score Closest driver Most urgent ticket The Heap doesn't decide w

"Finding something quickly and finding the best thing quickly are two completely different engineering problems." So far in this series, we've explored one of the most common behaviours in software systems: Fast lookup. Whenever a system already knows what it's looking for—a User ID, Product ID, Order ID or Session ID—a HashMap becomes an excellent choice. But not every software problem works this way. Imagine you're building a ride-sharing application. A rider requests a cab. The system doesn't already know which driver to assign. Instead, it must answer a different question: "Out of all available drivers, who is the best choice?" Now consider a task scheduler. Hundreds of jobs are waiting to run. The scheduler doesn't ask: "Find Job #123." It asks: "Which job should run next?" Or imagine a gaming platform. Thousands of players are competing. Nobody asks: "Find Player ID 1057." Instead, users ask: "Who are the top 10 players?" These problems are fundamentally different from fast lookup. They're not about finding a specific object . They're about finding the best object according to some priority. This shift in thinking introduces another important design behaviour. Fast Lookup vs Best Selection Let's compare two different requirements. Requirement 1 Customer ID = 1052 ↓ Retrieve Customer The system already knows exactly what it needs. The challenge is retrieving it efficiently. Requirement 2 Available Drivers ↓ Find Nearest Driver ↓ Assign Ride The system doesn't know the answer yet. It must compare multiple candidates before making a decision. These two behaviours may look similar. In reality, they solve completely different engineering problems. Every Software System Doesn't Search the Same Way Consider these questions. Find Order #50231 versus Find the highest priority order. Or: Retrieve Product ID = P1042 versus Recommend the most popular product. Or: Find Employee ID = 2107 versus Find the employee with the highest sales this month. The first question always

Most agent tooling is still built around a single conversation: one agent, one task, one terminal, one stream to babysit. Fine for small tasks, bad for real engineering work. Herdr is interesting because it treats that as the default shape of the work. The simplest way to describe it is: Herdr is tmux for coding agents. More precisely, it is an agent multiplexer that runs inside your existing terminal. It gives each agent a real PTY, keeps processes alive where the work is happening, shows agent state, and exposes a CLI plus a local socket API. That distinction matters. Herdr is not another desktop agent app. It is a binary you run where the code and terminals live: a server, a Mac Mini, a VM, a dev machine under your desk. Close the laptop, detach, ssh back later, reattach, even from a phone. The work did not die because your terminal window did. The throughput problem Coding agents changed the cost of starting work. I can ask one agent to explore a bug, another to write a failing test, another to draft a migration plan. The bottleneck is supervision. The problem is that normal terminals do not understand supervision. tmux and Zellij give you persistence and panes, but they do not know whether an agent is blocked, working, done, idle, or just sitting there after printing a question three screens ago. Desktop apps often understand the agent state better, but then the workflow is stuck to the machine with the GUI. Worktree orchestrators can coordinate parallel tasks, but they usually want to own the workflow. Herdr sits in a useful middle: terminal model, plus agent awareness. The performance multiplier is not magic. It comes from four practical properties: Multiple agents run in real PTYs, each with its own shell, logs, prompts, and process state. Herdr rolls up semantic state, so you can see which agents are blocked, working, done, or idle. The server owns the panes, so sessions survive client detach, laptop sleep, and terminal death. The CLI and socket API let scr

The pitch sells itself. An assistant that's entirely mine, running on my own machine, needing no connection, with nothing I type ever leaving the room. No company counting my tokens. No subscription. No outage on someone else's servers wrecking my afternoon (I'm looking at you, Anthropic, and your recurring outages). I wanted that badly enough that I spent a few months chasing it, and I want to tell you honestly where it left me. 24GB sounds like plenty until you load a model My Mac has 24GB of memory. This felt generous when I bought it, but then you load a real language model and that number shrinks fast. The system keeps its cut because the computer needs to keep running, and what's left for the model is closer to two-thirds of the sticker figure. The models actually worth trusting sit right at that ceiling or just past it. So you have to choose: a model that fits comfortably and isn't very bright, or a smarter one that leaves the machine gasping. The obvious fix is more memory, but have you seen memory prices lately? The timing could not be worse. Memory got expensive in a way that still surprises people who haven't shopped for it in a while. DRAM has roughly doubled in price since the start of 2025, and the analysts who watch this space think it could climb another 70% or so across 2026. Storage is worse in spots. The raw NAND wafers that SSDs are cut from are trading at something like eight times where they sat in the middle of last year, and a 4TB drive I'd have paid about $250 for not long ago now wants north of $700 — and because the market is so volatile right now, when this blog post goes live these numbers might be totally different because it's 2026 and who knows how much RAM and SSDs will cost. The reason for this insanity is also the reason behind half the stories in tech right now — AI. The big datacenter buildouts are on track to swallow around 70% of the world's high-end memory this year, and the cloud giants have signed contracts that lock up prod

How AI Is Transforming Software Development Workflows in 2026 By 2026, AI has moved far beyond autocomplete and boilerplate generation. It has become an integral, intelligent partner in the entire software development lifecycle. From writing initial architecture to diagnosing production incidents, AI agents are embedded into the fabric of modern engineering workflows. This transformation is not just about speed—it's a fundamental shift in the way developers think, collaborate, and deliver software. The Rise of AI-Native Development Environments The days of classic IDEs with a chat sidebar bolted on are behind us. In 2026, AI-native development environments are the norm. These IDEs are built around context-aware AI models that understand not just the syntax but the semantic intent of the codebase. Tools like Cursor and Windsurf have evolved into full-blown autonomous agents that can navigate large codebases, propose cross-file refactors, and even execute multi-step changes with minimal supervision. Consider a common task: adding a new payment gateway. In a traditional workflow, a developer would manually trace API routes, update database schemas, and write integration tests. In 2026, the developer simply describes the requirement in natural language. The AI agent explores the existing adapter patterns, creates the new integration, updates configuration files, and runs the test suite. The developer reviews the diff, tweaks edge cases, and signs off. This paradigm shift has accelerated feature delivery by an order of magnitude. Intelligent Automated Testing and Debugging Testing has always been a critical yet time-consuming part of development. AI in 2026 has revolutionised this domain. Instead of writing every test case manually, developers use AI to generate exhaustive test suites that cover edge cases, security vulnerabilities, and performance bottlenecks. The AI analyses the code's control flow, historical bug data, and production logs to generate tests that would
