I’m currently relearning the Core Three — HTML, CSS, and JavaScript — as I work toward becoming a full-stack JavaScript developer. Before I came back to learning software, I spent 22 years working industrial turnarounds. One lesson from that world has followed me into software engineering: Never trust a single point of failure. In industrial maintenance, there’s a safety practice called double block-and-bleed . Instead of trusting one isolation valve, you use two independent valves with a bleed point between them. If one valve leaks, you know immediately. The entire system assumes individual components can fail. Safety doesn’t come from perfect parts. It comes from independent layers of protection. That idea completely changed how I think about CI pipelines. When I first started relearning web development, my mindset was simple: Run Lighthouse. Everything green? Great. 100 across the board locally? Even better. Ship it. Different results after deployment? Uh-oh. Now I see Lighthouse as one checkpoint — not the finish line. A fast website can still have accessibility issues. An accessible site can still have broken metadata. Good SEO won’t catch rendering bugs. Passing unit tests won’t tell you if the generated HTML is malformed. Every tool has blind spots. No single tool should get the final vote. So instead of asking: “Did my tests pass?” I ask: “What kinds of failures could still slip through?” That question naturally leads to layered validation. Formatting Linting Type checking Accessibility checks Performance audits HTML validation SEO analysis Manual review None of these tools is perfect. Together, they’re much stronger than any one of them alone. The more I learn about software, the more I find myself applying lessons from heavy industry. Different environment. Different risks. The same engineering mindset. Assume components will fail. Design systems that fail safely. That’s becoming the philosophy behind every test matrix and CI pipeline I’m designing. What’s

When I first started learning Solana, one of the biggest questions I had was: "If there are no usernames or passwords, how does the blockchain know who I am?" As a Web2 developer, I was used to creating accounts with an email address, choosing a password, and relying on a company to manage my identity. After spending several days learning Solana, I realized blockchain approaches identity in a completely different way. Identity in Web2 Think about all the accounts you have today. GitHub Gmail Facebook LinkedIn Your bank Every service asks you to create another account. Each company stores your username and password in its own database. Your identity exists because they say it exists. If they suspend your account or delete it, your access disappears. In other words, your identity is owned by the platform. Identity on Solana On Solana there are no usernames. There are no passwords. There isn't even an account registration page. Instead, your identity begins with one thing: A cryptographic keypair. A keypair consists of: A Public Key A Private Key When I generated my first wallet using the Solana CLI, I immediately had a new blockchain identity. For example: Public Key: AxfVXDX7jsCw7vSnwut9hA7oX4UykE3ZeiNF6cxCKvpf This public key becomes my wallet address. Anyone can send tokens to it. Anyone can view its transactions. But nobody can spend funds from it. Why? Because only I possess the private key. Think of SSH Keys The easiest comparison for Web2 developers is SSH. When connecting to a Linux server: the server knows your public key you prove ownership using your private key Solana works almost exactly the same way. Except instead of logging into one server... you're interacting with an entire blockchain. Every transaction I make is digitally signed using my private key. Validators verify the signature before accepting the transaction. No password is ever transmitted. No administrator approves my login. The mathematics prove my identity. Why Wallets Matter One thing I f

Google is now deleting all accounts that do not, and have never had, phone numbers associated with them if they haven't logged in within a year or so. "Urgent: Sign in to your Google Account if you want to keep it" But then it doesn't matter if you log in with the correct username and password and receive the PIN via your email. This is isn't enough. Unless a phone number is somehow added to the account one gets, "You can’t recover your account at this time because Google doesn’t have enough inf
