Technology

When people talk about building a website, it’s common to use an example name rather than the name of an actual website. And when people ask questions about their websites, they often use a placeholder instead of the real name. This all makes sense, but when it isn’t done right, it can lead to problems. To see why, let’s start with the story of a Web host and its employees.

Web development on the frontend has come a long way from writing scripts and putting them directly into a Web page. Build tools and frameworks make it much easier to build entire applications that run in the browser, far beyond anything thought possible when JavaScript was first created.

Even so, it’s still possible to do it the old-fashioned way, and it turns out we don’t actually have to give up everything that modern Web development has brought us.

Last month I wrote a blog post about how to set up Let’s Encrypt for a Docker-based Web application. However, it contained a major error which I only discovered later on. I corrected it in the original post, but as I thought about it some more, I realized that there were some lessons to be learned, both about the specific technologies and software in general.

Encryption via HTTPS is something that virtually every website should support, and Let’s Encrypt lets you set this up (mostly) automatically, and for free.

I recently migrated a personal server to use Docker, and this is how I set up HTTPS certificates on it.

I recently got back from a trip, and it turns out that the microSD card plugged into my MP3 player has gone missing. (I previously wrote about why I still use an MP3 player to listen to music.)

Thankfully I take regular backups of my music so it’s just a matter of getting a new microSD card and restoring the files from the backup.

I sometimes get e-mails from job recruiters. Since I am currently employed in a decent position I haven’t paid too much attention to them. Although I know that I should continue to be open to new opportunities, sometimes I can’t help but wonder when I receive some of them.

A while ago I took one of the old desktop computers in the house and turned it into a basic home server. Right now its main functions are printing and file storage, and most of the time it can be turned off. To make this easy, I’ve kept the default behavior for the power button to shut down the system. But just shutting down a server like this is risky. What if someone is still logged in and working on something?

I bought a new car in 2020, and while I was test-driving it, I noticed something missing: an auxiliary audio (“aux”) port.

I still use a portable music player (sometimes called an “MP3 player”) to listen to my music.

Security questions are questions about personal details (like, “What was your first car you drove?” and, “What was the first concert you attended?”) that are meant to help recover your account in case something happens like you forgot your password.

As Wired writes, security questions are insecure. Why? It boils down to two things:
