Now that we have a mental model of how Solana works, it’s time to actually use it. We’ve talked about accounts holding state, programs containing the logic, instructions telling those programs what to do, and transactions bringing those instructions together. Creating an SPL Token Mint is a good place to see all of those concepts working together. In this part, we’ll create and initialize an SPL Token Mint on Solana Devnet, but more importantly, we’ll break down what is actually happening ...

I maintain a small collection of single-purpose web tools. Last month I built a favicon checker: you type a URL, it reads the icon declarations in the HTML head, probes every referenced file, and also hits /favicon.ico directly, because plenty of software still requests that path without ever reading your HTML. The first thing you should do with any auditing tool is point it at your own stuff. So I did. Ten sites, all built by me, all shipped and verified in browsers I actually use. All ...

The problem that wouldn't leave me alone A few months ago I was auditing a client's site and had five tabs open: Hotjar for heatmaps, Ahrefs for SEO, a spreadsheet for tracking fixes, ChatGPT for "why is this page not converting," and a half-finished Notion doc trying to tie it all together. Somewhere around tab four, it hit me: none of these tools talk to each other, and none of them tell you what to actually do . Hotjar and FullStory show you that people bounce off a page. The...

The problem I was trying to solve Candidates send hundreds of applications. Companies receive thousands of resumes. Most candidates never hear back. Both sides exhausted. Most of the effort wasted. The insight that changed my thinking: senior engineers don't apply to jobs. They get headhunted. A recruiter finds them, reaches out, and they evaluate the opportunity on their terms. Why is that only available to senior people? It shouldn't be. What I built Wrkmark ...

A pragmatic look at the hidden costs, the small-batch myth, and why user trust matters more than deploy frequency. I. Introduction "CI/CD will save you money. It will make your team faster. It will eliminate bugs. It is the only way to build modern software." We've all heard this. The industry preaches CI/CD as a universal solution. Every conference talk, every DevOps blog post, every vendor pitch tells you the same thing: adopt CI/CD or be left behind. But is it...

Much of the traditional software operations we deal with are online, we click a button, wait for a moment, and the transaction or operation is completed. But there is a big area that deals with software operations that require offline processing. For example, background processing of jobs, e.g., OpenAI training/improving its existing GPT models behind the scenes using the data it gathers from its users. Batch Processing Whenever such an offline system runs a job that typically...

“Let’s split it into agents” has become the AI equivalent of “let’s make it a microservice.” Sometimes the boundary is useful. Sometimes it only creates more state, more coordination, and a harder failure to explain. The most dangerous assumption is that separate agents should run in parallel. Parallelism is safe only when the branches are genuinely independent. If one branch changes the world while another is evaluating it, both agents can make locally reasonable decisions that are unsafe...

We run our team's AI stack on our own hardware. The weekly development log starts the week of January 19, 2026, the repository was created on February 3, and today it sits at roughly 2,100 commits under MIT. I want to write about four things that broke, because every one of them is in the public changelog and you can check my work. No war stories I can't back up. The setup A Mac mini runs the application: API and web under PM2, with PostgreSQL, Redis, and the sandboxed agent, ...

A friend and I intend to start a business in the near future and would love to have a great human designer make us some great human (logo/web) designs. I am a programmer and painter by training but have no talent for graphic design and have no idea where to find great designers. So, I'd love to know if you know of any places to look/any great ones you have experience with. We are primarily searching for help with our logo/branding and design for our launch website. A few requirements: Be...

The Xbox Helix is estimated to be a year or two away, and fans are wondering whether it will have a disc drive or not.

Feature flags can control real production behavior. Here’s why teams need ownership, observability, permissions, rollout plans, and cleanup.

Why prose rules fail for AI coding agents, and how a demotion ladder of hooks, write partitions and build-enforced checks holds the line instead.

Industrial MLOps spans trust zones, remote sites, OT networks, local runtimes, and MLSecOps controls. Here’s why it differs from conventional MLOps.
