I have a couple of always-free compute instances on Oracle Cloud. By default, each instance gets an IPv4 address, and IPv6 is not enabled.

I tried enabling IPv6 using instructions I found on the Internet, but:

• it doesn't work for my Oracle Linux 8.4 instance
• even if it did, we have to manually obtain the IPv6 address using /etc/rc.local -- this doesn't seem to be the best practice, especially since this is a systemd distro

Hey, I'm all for simplicity and I love SysV init scripts, but if the distro is a systemd distro, then I'll use systemd. Just like the reason why I have an Oracle Linux instance on Oracle Cloud -- it's supposed to be the best-supported OS on their cloud. Yes, it's just another clone of RHEL, but I thought it would somehow be better tuned for Oracle Cloud environment...

I created a Stardust instance on ScaleWay, and used IPv6 exclusively (didn't use IPv4, much cheaper this way).

The issue is, dnf would often not work. After using -d 3 to figure out where it stalls, it became clear that dnf was resolving the mirror domain names to IPv4, and then failing to connect to them because we don't have IPv4.

So, here's a snippet taken from a Vue.js project:

export default {
    name: 'Room',
    components: {
        InfiniteLoading,
        Loader,
        SvgIcon,
        ...

But we don't see SvgIcon anywhere in the HTML template. We see this instead:

    <svg-icon name="emoji" :param="emojiReaction ? 'reaction' : ''" />

How does SvgIcon become svg-icon? By magic, it seems.

Oh, how I love C and its (almost) no-surprises syntax!

Some time ago I was trying to make bash start faster. There, I described a solution to load nvm and SDKMAN! faster. However, that solution has a few issues.

As we install development environments in our system, we may notice that terminal start-up can become slow. Some people notice it, some don't -- but the reality is, it's there.

Sometimes, we would like to know how long a command takes, and which part of the script takes the longest time to run.

When we install a new development environment, the installer will usually modify ~/.bashrc or ~/.profile. However, this is not very clean, because sometimes the entries are not removed when the development environment is uninstalled.

I just found out today that GitHub has changed the default name of the master branch to "main". This is supposedly done to avoid any references to slavery (master, slave, get it?), but I think it's a load of bullshit.

I got an error while trying to build this blog in a temporary directory. This might be a webpack bug -- or not.

Before, we need to run this command to deploy a Docusaurus site to GitHub Pages:

$ GIT_USER=wpyoga DEPLOYMENT_BRANCH=gh-pages USE_SSH=true yarn deploy

If we don't use SSH, we will be prompted for a password. Right now I don't even know my own password (it's stored in my password manager), so this is not a good idea. And I already use SSH to work on GitHub repositories anyway. So this is not a good way to do things.
