Web Hosting Tips & Resources From NameHero
Bash math refers to the mathematical operations you can conduct on the Linux terminal. Normally, you wouldn’t associate bash with math operations – after all, why would you choose to type in clunky commands on the terminal, when you could open a calculator instead? However, there are some surprisingly useful use case scenarios where it […]
As we head into 2025, I can’t help but reflect on the last nine years since launching NameHero. Back in 2015, my mission was simple: make it easy, affordable, and scalable for businesses to have the same level of hosting infrastructure I perfected for my own online ventures. Fast forward to today, we’ve supported over […]
We use the xxd command in Linux to convert a file into its hex equivalent and to show the hex output side by side with the ASCII representation. This might seem like a niche use case scenario, but it’s surprisingly useful for debugging. There are certain file formats, for example, that are supposed to start […]
As we close out 2024, I’ve been reflecting on the goals I set for myself and NameHero over the past year. Personally, I’m not a fan of “resolutions”—they’re like January gym memberships: hot for a few weeks and then abandoned by February. Instead, I take a step back, review what I’ve accomplished, and re-evaluate what […]
The “envsubst” tool is part of the GNU’s “gettext” package that programmers use to create multilingual programs. We use envsubst to substitute environment variables in a file or a data stream. This is particularly useful when creating and adapting configuration file templates in a variety of scenarios. For example, you sometimes have a template configuration […]
Earlier, I’d written about how the awk statement in Linux can be a superior alternative to grep in many situations. One of those included the ability to perform complex operations, including control loops. The “if-else” statement is one of the most basic control loops in all languages. While it’s strange to view awk as a […]
Most people working on a git repository, have done so by cloning a remote one. The thousands of developers who work on projects everyday, have mostly taken an existing repo and are working on it. When you do this, git sets up a connection to the remote repo and calls it the “origin”. This makes […]
SIGSEGV is a signal sent by the operating system to a process indicating that the process has attempted to access memory that it shouldn’t. This kind of error is prevalent in low-level code – that deals directly with system code, for example. These days, SIGSEGV errors are rare because of improvements in modern programming languages […]
While the purpose of git is to maintain a faithful record of a project’s history, it’s usually not a good idea to blindly include every single change, including mistakes or tiny commits that should be merged into a single one. I’ve written before, about how we can use git squash to keep a clean project, […]
Linux uses the concept of “streams” to handle input and output messages. Specifically, there are three: These streams are defined by the environment in which a command operations, and doesn’t depend on the command itself. So if a script has an output – say via an “echo” statement or it throws an error, these messages […]
