If you’re reading this post, it’s quite likely that you’re fully aware that Red Hat provide a no-cost Red Hat Developer Subscription for individuals. With this subscript you can use it run RHEL for free. The subscription only lasts one year, and when it expires it can’t be renewed. You must re-register. I have a test RHEL vm, but I hardly use. So today when I turned it on and logged into it, the following message came up when i tried to update the system:...

It’s currently almost 23:15, and I’m already sleepy. Therefore, this is going to be a short note on how I fixed an minor but annoying issue nvim-treesiter (Neovim’s plugin) on openSUSE Leap (15.5). The error message is or was as below: nvim-treesitter[yaml]: Error during compilation cc: error trying to exec 'cc1plus': execvp: No such file or directory Press ENTER or type command to continue I don’t code in C++ nowadays, but the error looks like the C or C++ compiler was missing....

I already wrote a blog post on How to install AWS CLI on RockyLinux, where I shared how to leverage the RPM package from EPEL repository. So what do I need to create a post here? Well, when I tried to use the same method to install the AWS CLI on an AlmaLinux 9.2, there was an issue with dependency. Here is what happened: [kenno@wedev1 ~]$ sudo dnf install awscli [sudo] password for kenno: Last metadata expiration check: 0:05:08 ago on Sun 20 Aug 2023 18:35:23....

When you are finished with a WorkSpace, you can delete it. You can also delete related resources. In this post, I’ll be using AWS CLI to delete a WorkSpace that is no longer needed. To delete a WorkSpace using AWS CLI, we can use terminate-workspaces command [2]. But first, I’d need to find the workspace id. ➜ aws workspaces describe-workspaces --query 'Workspaces[].WorkspaceId' --output text ws-9xm222222 Now that I got the WorkSpace id as ws-9xm222222, I can proceed to terminate this WorkSpace....

I need to stop a WorkSpace now and I don’t want to login to AWS WorkSpace console. The following is the steps I’m literally taking to achieve this goal. Find out the WorkSpace ID, assuming that my AWS CLI has been setup correctly. ❯ aws workspaces describe-workspaces { "Workspaces": [ { "WorkspaceId": "ws-9xm222222", "DirectoryId": "d-9767555555", "UserName": "kenno", "IpAddress": "172.xx.x.xx", "State": "AVAILABLE", "BundleId": "wsb-clj855555", "SubnetId": "subnet-0a4ae4b324a799999", "ComputerName": "A-2B99WV33TITAN", "WorkspaceProperties": { "RunningMode": "AUTO_STOP", "RunningModeAutoStopTimeoutInMinutes": 60, "RootVolumeSizeGib": 80, "UserVolumeSizeGib": 50, "ComputeTypeName": "STANDARD", "Protocols": [ "PCOIP" ] }, "ModificationStates": [] } ] } We can see that the WorkSpace ‘ws-9xm222222’ is in AVAILABLE state....

The following is a sample of text opening in vim/neovim with line numbers: 1 What would be the command to delete one word backwards? 2 I know we can use ‘db’ to delete backword, and it would work 3 as what I wanted if the cursor is on the last character. Assuming that my cursor is under letter ‘a’ of the word ‘command’ in line 1, and I want to delete the whole word ‘command’....

Debian publishes their releases of Amazon Machine Image (AMI) for bookworm at Debian bookworm on Amazon EC2 [1]. There, you can find the AMIs for various regions and two architecture amd64 and arm64. Another way to search for AMI for Debian 12 (bookworm) is to use AWS CLI with describe-images. Here is an example on how to list the 3 most recent AMIs of Debian 12 (amd64 architecture), sorted by most recent to the oldest:...

As of today, Jellyfin Media Player is not available on (official?) repos for OpenSUSE Tumbleweed. To install it, I need to first add a repository, kind of like Fedora Copr, which provides this package. $ sudo zypper addrepo https://download.opensuse.org/repositories/home:playablepliable/openSUSE_Tumbleweed/home:playablepliable.repo [sudo] password for root: Adding repository 'home:playablepliable (openSUSE_Tumbleweed)' ......................................[done] Repository 'home:playablepliable (openSUSE_Tumbleweed)' successfully added URI : https://download.opensuse.org/repositories/home:/playablepliable/openSUSE_Tumbleweed/ Enabled : Yes GPG Check : Yes Autorefresh : No Priority : 99 (default priority) Repository priorities are without effect....

First check if the Wi-Fi device is enabled or not: $ nmcli radio wifi If the output shows that the Wi-Fi is disabled, then it can be enabled with: $ nmcli radio wifi on If we already know the access point, then skip the following step. Otherwise, to identify the access points, run: $ nmcli dev wifi list Supposed we want to connect to the access point named ’totoro’, and the password is ’t0t0r02023’, we can connect to it by running the following command:...

This post is related to the previous one about changing a theme in Hugo. After I changed the theme to “PaperMod”, I realized that each article or blog post is under ‘post/date’ URL path. For example, the following is the permanent link/path of a post: https://blog.khmersite.net/post/2023/06/changing-hugo-theme/ Previously, there was no word post in the URL path, and I still want it gone again with this new theme, as below. https://blog.khmersite.net/2023/06/changing-hugo-theme/ The problem is, I forgot how it was done!...
