Your Job Search Is Not a Lottery

There is a special kind of productivity theater that happens during a developer job search. You wake up motivated, open LinkedIn, and apply to 27 positions before breakfast. You press the Easy Apply button with the precision of a professional gamer. By the end of the week, you have submitted 143 applications, updated a spreadsheet with several impressive numbers, and developed a minor emotional dependency on refreshing your inbox. Unfortunately, your inbox still looks like an abandoned shopping mall. No interviews. No useful feedback. No clear explanation. Perhaps two automated emails thanking you for your interest before informing you that the company decided to “move forward with other candidates,” a sentence that has become the corporate version of disappearing into the fog. So you decide to solve the problem by applying to another 200 jobs. This is not a strategy. It is email-based agriculture. You are throwing resumes into the soil and waiting for a recruiter to grow. Volume Matters. Blind Volume Does Not. Let us begin with an uncomfortable truth: getting your first developer job usually requires applications. Sometimes it requires many applications. The market will not discover your GitHub profile through divine intervention. A recruiter is unlikely to wake up in the middle of the night with a mysterious urge to search for junior developers who recently deployed a to-do list. You need to put yourself in front of companies consistently. However, there is a significant difference between applying consistently while improving your positioning and clicking every blue button on LinkedIn until one of you collapses. Volume is useful when it generates information. Blind volume only produces exhaustion. If you apply to 300 jobs with the same generic resume, the same generic portfolio, and the same vague explanation of your skills, you are not running 300 experiments. You are repeating the same experiment 300 times and acting surprised when the result remains unchanged.

The loop I didn't notice closing

The loop I didn't notice closing Seven weeks ago I started using AI for work. Two weeks after that, I published an article. Seven weeks after that — today — the article is one of sixteen, and they are all in a memory file that the AI reads at the start of every new conversation. I didn't notice the loop until I named it. This is a note about that loop, what it is, what it isn't, and why I keep publishing even though the loop doesn't strictly need me to. The shape It runs like this: I decide what to do. I work it out with the AI — usually in dialogue, sometimes by pasting raw code or data. The dialogue becomes a record. Sometimes a memory entry. Sometimes a published article. The record becomes context for the next conversation, which informs the next decision. It didn't look this clean while it was happening. The numbering is hindsight. From inside, the steps overlap. The first step is the one I keep. Direction is mine: what to build, what to write, what to negotiate. The history that shapes those decisions — twenty-four years of solo work, my company, my family, my health — is also mine. The AI is not setting direction. The second step is where most of the leverage is. I describe what I want to do as completely as I can, sometimes by handing over source code. Then I ask: does this look right? Is there a path I'm missing? Where would this break? I'm opening drawers — possibilities I half-saw in my own head — and checking which ones open cleanly. When one opens cleanly, that is the GO signal. Not "will this succeed" but "this is doable, so do it." The third step happens almost without effort. The conversation already exists as text. Some of it becomes a memory entry I add deliberately. Some of it becomes raw material for an article. The article writes itself partly because I have already explained the thing to the AI. The fourth step is the one that took longest to arrive — and the one I want to be most careful about describing. Three phases, not one The loop didn't

Auto-Generated CUDA Kernels Need Kernel-Level Validation

An LLM-written kernel benchmarked 38% faster on a microbench. Here is what kernel-level validation showed it actually did at runtime. TL;DR Multi-agent LLMs are now writing CUDA kernels (RightNow AI’s AutoKernel, Meta’s KernelEvolve, a multi-agent system claiming 38% speedup on Blackwell). Source-level benchmarks measure clean throughput on a single isolated kernel. They do not measure SM occupancy under co-scheduling, DRAM bandwidth saturation, dispatcher off-CPU during a real serving workload, or NCCL wait correlation with sibling kernels. Kernel-level validation closes that gap: an eBPF trace of the same kernel running under the same workload as production answers all four questions in one capture. The kernel-writing wave Three pieces of work in April surfaced the same pattern: agents generate CUDA kernels, then quote a single throughput number against a baseline. RightNow AI’s AutoKernel (announced Apr 6) – LLM agents iteratively rewrite CUDA kernels for a target metric, claiming substantial speedups on selected microbenchmarks. Meta’s KernelEvolve – similar shape: agents propose kernel variants, rank by throughput, keep the best. Multi-agent system on Blackwell (Apr 29 reports) – claims a 38% speedup on a public kernel benchmark using a coordinated agent setup. All three are real research, all three produce real kernels, and all three report numbers that come from microbenchmarks. The microbench setup is exactly what you want for the optimization loop. It is not what you get in production. What microbenchmarks do not see Run an LLM-generated kernel under nvprof or nsight-compute on an otherwise-idle GPU and the throughput number is real. Put the same kernel in front of a vLLM serving workload and four properties change immediately: SM occupancy under co-scheduling. The kernel that achieves 95% SM occupancy in isolation will achieve 40-50% with three other kernels sharing the same SMs. The optimizer never sees this regime. DRAM bandwidth saturation. A kernel tha

I Spent 2 Months Building a 150+ Tool Website with $0 Server Cost

📚 This is Part 1 (Opening) of the UtlKit Tech Series — Next: [Architecture & Trade-offs →] As a frontend developer, I've used countless online tools. And almost all of them suck: Sign-up required — just to format a JSON string? Ad overload — the actual tool gets squeezed into a corner Privacy concerns — your JSON might contain API keys, and the tool sends it to a server Fragmented — formatters on one site, Base64 on another, hashing on a third So I decided to build one that doesn't: no sign-up, no ads, pure client-side computation, data never leaves the browser. The goal was simple — if I need this tool, someone else does too. The result is utlkit.com : 150+ tools, 8 categories, zero server costs. Requirements Requirement Meaning Pure client-side All logic runs in the browser Zero server cost Static hosting, no Node.js backend 150+ pages One page per tool, SEO-friendly Bilingual (EN/ZH) i18n support Dark/Light mode User preference Mobile responsive Works on all devices Why Not Other Frameworks? Option Pros Cons Verdict Vanilla HTML/JS Simple Managing 150+ pages is painful Too slow VuePress / VitePress Fast Docs-oriented, not for interactive tools Not flexible enough Nuxt SSR Powerful Needs a server Violates zero-cost principle Next.js 15 + output: 'export' SSR SEO + client interactivity + static hosting Has pitfalls (covered later) ✅ Best balance The Key Decision: output: 'export' // next.config.js const nextConfig = { output : ' export ' , // Static export trailingSlash : true , // Required for static files images : { unoptimized : true }, // No image optimization server } This means: ✅ Build output is plain HTML/CSS/JS files ✅ Deployable to any static host (Cloudflare Pages, Vercel, GitHub Pages) ✅ Zero server cost ❌ No API Routes, no Server Components, limited dynamic routing Deployment: Zero Cost on Cloudflare Pages Build output : out/ directory, ~14 MB Hosting : Cloudflare Pages Domain : utlkit.com Monthly cost : $0 Build Pipeline npm run build → next build ( o

Developers Confess: The Unfiltered Truth

We asked developers to spill their little dirty secrets, the lies they tell their managers and what actually creates tension in teams. One theme that kept coming up was the gap between how software development looks from the outside and what it actually looks like in practice. submitted by /u/aisatsana__ [link] [留言]

Testing Discipline: A Beginner's Guide

Image by upklyak on Magnific Run an application. Click a few buttons. If the terminal doesn't have errors, then everything is working. Right? What's the point of writing tests if all seems to be fine. Let's explore testing discipline and why it's a habit every developer should build early. What is Testing Discipline? Testing discipline is the habit of verifying that your code works. It's not something you do at the end of a project. It's something you build into your development process. The goal is simple. Catch bugs as early as possible. A bug found while writing code usually takes minutes to fix. The same bug found in production can take hours to investigate, reproduce, and resolve. The earlier you find problems, the less expensive they become. Different Types of Tests When people talk about testing, they're usually referring to three categories. The first is unit testing . A unit test checks a single piece of functionality, usually a function or method. These tests are fast and easy to write, making them the best place for beginners to start. Next are integration tests . These verify that different parts of your application work together correctly. For example, does your service communicate properly with the database? Finally, there are end-to-end tests . These simulate a real user interacting with the application from start to finish. They provide the most realistic results but are usually slower and more complex. As a beginner, I recommend that you should focus on unit tests first. Different Testing Approaches As you continue learning, you'll come across different testing methodologies. One of the most popular is Test-Driven Development , often called TDD. The idea is simple. Write the test first. Watch it fail. Write enough code to make it pass. Many developers like this approach because it forces them to think about requirements before writing implementation details. You may also hear about Behaviour-Driven Development , or BDD. This approach focuses on desc
