Flags.gg Rust Support

Thu, 15 May 2025 00:00:00 +0000

I have added rust support to flags.gg and by that I mean you can now call flags.gg inside rust

but you can also turn flags on locally

use flags_rs::{Auth, Client};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize the client
    let client = Client::builder()
        .with_auth(Auth {
            project_id: "your-project-id".to_string(),
            agent_id: "your-agent-id".to_string(),
            environment_id: "your-environment-id".to_string(),
        })
        .with_memory_cache()
        .build();

    // Check if a flag is enabled
    let is_feature_enabled = client.is("my-feature").enabled().await;
    println!("Feature 'my-feature' is enabled: {}", is_feature_enabled);

    // List all flags
    let all_flags = client.list().await?;
    println!("All flags:");
    for flag in all_flags {
        println!("  {} ({}): {}", flag.details.name, flag.details.id, flag.enabled);
    }

    Ok(())
}

Flags.gg Golang Support

Sun, 30 Mar 2025 23:00:00 +0000

I have added Golang support to flags.gg and by that I mean you can now call flags.gg inside go

but you can also turn flags on locally

package main

import (
	"github.com/flags-gg/go-flags"
	"log"
	"os"
)

func main() {
	flags := flags.NewClient(flags.WithAuth(flags.Auth{
		ProjectID:     "tester",
		AgentID:       "tester",
		EnvironmentID: "tester",
	}))

	if flags.Is("test-flag").Enabled() {
		log.Println("test-flag enabled")
	}

	if flags.Is("test flag 2").Enabled() {
		log.Println("test flag 2 enabled")
	}

	_ = os.Setenv("FLAGS_TEST_FLAG_3", "true")
	if flags.Is("test flag 3").Enabled() {
		log.Println("test flag 3 enabled")
	}

	_ = os.Setenv("FLAGS_TEST_FLAG_4", "true")
	if flags.Is("test-flag-4").Enabled() {
		log.Println("test flag 4 enabled")
	}

	log.Println("flags enabled or disabled")
}

CV

Tue, 25 Mar 2025 00:00:00 +0000

CV and Description

Its probably a good idea to have a CV and description of somewhere.

I have been a software engineer for over 25 years, working on various projects and for some very well known companies.

Personal projects

All these github orgs are mine, I also recently soft-launched a side project of Flags.gg which is a feature flag system like LaunchDarkly

LinkedIn My LinkedIn Account

Keloran My Personal github account

Flags.gg

Mon, 06 Jan 2025 14:10:25 +0000

Flags.gg Launched

On 2024-12-24 I soft launched (soft because not all features are finished yet, but enough to get it launched) the service

The service is works with the majority of features in place

Live Features

Multi Project

If you have a plan that supports multiple projects, then the support exists that flags don’t clash with each other
Multi Agent

You might need multi agents, e.g. a dashboard and a landing page (like flags.gg)

1tn.pw

Sun, 15 Dec 2024 23:03:07 +0000

This is a very simple url shortner, it does exactly that

It has an increadbly simple API

Very simple API

Create

curl --request POST \
  --url http://api.1tn.pw/create \
  --header 'Content-Type: application/json' \
  --data '{
 "url": "https://keloran.dev"
}'

Returns

{
 "short": "yJjWqM",
 "url": "https://keloran.dev"
}

Get

curl --request GET \
  --url https://api.1tn.pw/yJjWqM \

Returns

{
 "long": "https://keloran.dev"

Todo List

Tue, 19 Dec 2023 08:18:04 +0000

Another project

So I decided to create another project, this was mainly to re-learn react, and to get back into the swing of things, so what is it

Well if you can’t guess by the title, its a todo-list, specifically Todo-List.app

Features

Entirly private, encryption happens in browser
Storage is only of the encrypted form
Login is using Keycloak, so no “real” details are retained
Export/Import todo.txt

Unfinished features

Project support (its a very simple todo, only items and sub-items atm)

Cluster Update

Tue, 28 Mar 2023 11:21:05 +0100

Cluster Update

My kubernetes cluster runs on a mix of RaspberryPI 4s, and x86(AMD64) machines, but because I built it originally with only the raspberrys, my control plane was on a PI

Well that was working fine for nearly 2 years, but the SD card on the control plane died, which wasn’t a good time

So I decided to what I always do, and go nuts

Spending spree

So I purchased a few things to tackle this issue

Old iPads Modern Use

Sat, 04 Feb 2023 09:37:57 +0000

Old iPads with a Modern Use

I have gone quite heavy into home automation, not too extreme (mainly because I don’t have a lot of automated products) but enough that it has made an impact on my life, I have the following automations

Automatic lights in a few rooms
- Kitchen: the light comes on when you enter the room, and only turns off after it has been vacant for 5 minutes (if your stood at the stove and haven’t moved much I don’t want the light to go off)
- Dining Room: light comes on when you go past a sensor in the hall/stairs (there isn’t a sensor in the dining room)
- Living Room: light comes on when you enter the room, and goes off if there is no activity for 5 minutes and the TV isn’t on (sat at the sofa watching something shouldn’t turn the lights off)
- Stairs: Turn on when you enter the stairs either from the top or the bottom, turn off after 1 minute of no activity
- Bedroom: Turn on in the morning, turn off when everyone “should” have left the bedroom

Future plans

There are plans for future automations, every room has a temperature sensor in it, and will have wall heaters (I live in the UK) that turn on when the sensor detects the temperature not the heater detecting the temperature, this is to avoid it thinking “I’m nice and warm and 10ft from the nearest person screw them”

Mailspring Inverse Images

Mon, 09 Jan 2023 22:19:57 +0000

Inverse Images in Mailspring

So I run most apps in darkmode, and this can lead to a few issues, namely in Mailspring which does darkmode in the “easy” method, which is to inverse(100%) everything now this makes general emails really easy, the problem is when you get to images, because inversed images are horrible to look at

So I got bored over new year, and decided I was sick of looking at them, and because I use Dracula for everything, I set off on my journey

Broken i915

Mon, 03 Oct 2022 15:08:21 +0100

Well that was annoying

So I run arch on my framework, and because I’m slightly an idiot I didn’t have linux/linux-headers in the do not upgrade filter, now thats a lesson I won’t forget soon

I did the standard upgrade, which brought with it the latest (5.9.12) kernel with it, wish I remembered it did that, because when I rebooted, my display no longer worked, and once it got to sway, and didn’t initiate the eGPU, my FPS on sway was about 0.000005 so impossible to do anything

Systemd Homed Buildkit

Tue, 23 Aug 2022 14:34:09 +0100

Premise

So I decided to switch my home directory to use systemd-homed, now this is a cool system that works with btrfs and does snapshoting built in, this led to a few issues though

Issue

So because of the way containerd and buildkit use squashfs it can’t submount inside the homed directory

Fix

If you have multiple hdds then this is easier, if not your gonna have to create a directory on your system, doing it where I did it is not a good idea, but I’m not an expert

NerdCTL on ArchLinux

Tue, 26 Apr 2022 17:41:50 +0100

ArchLinux NerdCTL

Arch is a lot like Slackware and Gentoo, whilst it does have a package manager, you have to know what you want before things work

so NerdCTL has the ability to use buildkit to install stuff on multi-arch but that isn’t as easy as you would like and as such there are a few things that need installing to make it work

Steps

This will need YAY (well there are others but if you copy paste then its yay)

Framework Laptop

Tue, 26 Apr 2022 10:02:44 +0100

Framework Laptop

My MBP decided the touchbar and bridgeos was going to basiclly blow up, so because of this I decided it was time I tried to daily drive linux again

I bought a framework laptop with the following specs

i7-1165G7
64Gb DDR4-3200
1TB SN850
US Keyboard
UK PowerSupply
Expansions
- MicroSD
- 250Gb
- DisplayPort
- 2x USB-C
- USB-A

I decided to get the UK powersupply so that my wife could keep using my MBPs for her work laptop and it means that I have a pretty small power supply that can also be used with my soldering iron

Mistakes Were Made

Mon, 14 Mar 2022 22:12:30 +0000

Mistakes were made

Well I’ve had a fun weekend, on one side I “finally” caught covid and as such my concentration levels were very low, now that doesn’t make up for what I did but at least I have 1/2 an out

What happened

I decided to do a little cleaning up of my kubernetes cluster, and decided that I should remove some deployments that weren’t in use, that was going fine, but then I decided to try and move some of the things that were more “central” to their correct namespace,
correct is a probably the wrong word, since I do kind of follow the principle of a namespace for a service rather than a namespace for a project (e.g. all of chewedfeed's stuff goes in the chewedfeed one, some things should be seperate if they are used by multiple things)

Retro Board Update

Sat, 19 Feb 2022 13:50:20 +0000

Retro Board Update

Well after a couple of months of coding ive got about 50% through doing reto-board, major progress has been made, it is now techniclly possible to sign up for it,

you can’t yet make any boards, but there an example version of what a board will look like non of the functionality works in the example

it took quite a while for me to get the login to work, and the main reason to that is undocumented bits that I had to get working myself, for example “can I do this / userAllowed” is not a standard feature it seems at least not in the golang libraries for keycloak, so I had to go down a very long and winding path

K3OS

Sun, 06 Feb 2022 17:52:44 +0000

K3OS

K3OS is kinda self explanitory if you know what K3s is, if not then k3OS is Rancher’s k3s which is a kubernetes compatible version but a lot smaller

Why did I tell you that

Well now that bit is out of the way, I upgraded ubuntu on one of my raspberry pi 3’s, and at the same time upgraded k3s to the latest version, and that pi became almost impossible to use with kubernetes, pods failing all the time,
since I needed to wipe it anyway, and possibly replace with a pi4 (which are harder to find than rocking-horse-{redacted}) why not give k3os a shot, this is where the fun began

Update NerdCTL on RancherDesktop macOS

Thu, 03 Feb 2022 10:46:56 +0000

Issue

So you are already using RancherDesktop and NerdCTL from the betas congrats, but you want to use the multi-platform build

so you need to update Rancher and Nerd, well thats where the issue exists, Lima doesnt update NerdCTL automatically so you need to update your instances version

Fix

First you need to get into the instance

LIMA_HOME=/Users/<username>/Library/Application\ Support/rancher-desktop/lima \
	/Applications/Rancher\ Desktop.app/Contents/Resources/resources/darwin/lima/bin/limactl \
	shell 0 sudo --preserve-env=CONTAINERD_ADDRESS sh

Now that your in the instance, you need to update NerdCTL

Integrating Vault with 1Password in Kubernetes

Mon, 10 Jan 2022 17:14:04 +0000

Integrating Vault with 1Password in Kubernetes

I decided that I should probably get a real handle on my passwords and secrets in kubernetes, since kubernetes is not very good at keeping secrets

So I don’t generally take a helm chart or kube-schema at face value, this has more to do with I prefer to keep things in their own namespace rather than in “default”, because of this I tend to clone the chart first

Retro Board

Mon, 06 Dec 2021 15:31:36 +0000

Retro Board

Well I’ve started another project, retro-board.it this is just going to be a very simple app, that has a couple of options

Ask the user what the Company name is, this is to create a subdomain with that company name (if it doesnt already exist) - if the company name already exists then enter the password for the domain
Ask the user for a Team name
Ask if they would like to use single sign-on (Google | Github) or accounts

Team Board Setup

The team board starts with the following options

RaspberryPI cluster

Thu, 14 Oct 2021 10:39:53 +0100

Well I made Kubernetes cluster using Raspberry PIs, I largely followed the guide RasperryPI 4 Cluster

It has the following features

5 Raspberry Pi 4s, 4Gb RAM
1 DualCore x64, 16Gb RAM
1 DualCore x64, 4Gb RAM
4Tb storage distributed over the whole cluster
ClusterCTRL, this is so power goes through the backplane rather than having 5 seperate power sources

Things that are using the cluster, well this site for one

BugFix.es

Wed, 13 Oct 2021 15:05:44 +0100

This is a bug tracking system, any time an error happens on your site it tells bugfixes in the agent for your language,

then if the error occurs quickly or once in a while it informs the user some how

nothing is public yet (the javascript version released needs fixing)

Planned languages supported
* Go
* Javascript
* Swift

Planned notification systems
* Auto-create tickets
    * Jira
    * YouTrack
    * Jetbrains Space
    * GitHub
* Channel messages
    * Slack
    * Microsoft Teams
    * Jetbrains Space
* Email

K8sDeploy.dev

Wed, 13 Oct 2021 15:05:44 +0100

This project is so that I can deploy projects into my cluster using github pipelines

now that sounds simle enough, except there aren’t any (from my limited research) deployment agents for kubernetes that work on arm

So whats my plan, well this system works thus

Method

There is a github action that is triggered in your pipeline, this talks to an orchestrator on k8sdeploy

the orchestrator then sends a message to a queue with a topic for an agent that has been registered by you for your cluster

Kubernetes

Wed, 13 Oct 2021 14:55:05 +0100

Well I’ve decided that I should probably learn kubernetes, so I built a raspberry pi cluster

Home

Static Generator

Fri, 01 Jan 2021 14:55:05 +0100

Started a index generator, all it does is reads the projects and blog directory,

if there are pages in the project folder
- current folder, add to that section
- past folder, add to that section
if its in blog folder it adds those to that section

Very simple, I’ll add more features in future, but this is just very simple

Added a very simple editor Added an RSS generator

Future plans

~~Make it a simple editor, that generates the files themselves~~
~~Added RSS generator~~
Generate HTML pages from the CommonMark so that can be hosted outside of github.io

Keyboard Madness

Thu, 16 Apr 2020 14:55:05 +0100

Well I finally pulled the plug and bought a Planck,

rather than build my own though I went with a Planck EZ also rather than buy 1 like any sensible person, when it costs nearly 300 quid, I bought 2

and because obviously I’m npt to be trusted I decided to flash one and learn Workman, I have a couple of firmwares if anyone else is insane like me

Workman this layout is workman, but also moves the numbers on the upper layer to a reverse T pattern is the easiest way to explain it

ZSH Plugin

Thu, 30 Jan 2020 14:55:05 +0100

I decided that I should stick all my aliases and functions that I use into a zsh plugin, that way I can maintain it separately

Github

Home

BugFix.es Progress

Tue, 07 Jan 2020 14:55:05 +0100

Progress has been slow to start with, but that should now speed up

I have finished the authorizer, and moved the storage system to Postgres from Dynamo, the main reason for that is that a lot of the data is relational so it makes sense to put it in a relational database

Nest

This is the service where all CRUD operations take place, it is also what triggers Hive

Hive

This is the service that works out what to do with a bug, is it a new one, has it happened before, is it happening frequently, it also triggers the notification system

Going back to BugFix.es

Thu, 05 Dec 2019 14:55:05 +0100

I have decided to go back to BugFix.es and re-start development

mainly this is due to me needing a common bug/issue tracking system (this is not a ticket system like jira)

BugFix.es tracks bugs, so if a bug is sent to the system and it hasn’t been seen before or was seen a long time ago, or is happening a lot in a short period of time it creates a ticket / notification so development on it can be tracked/done

Basic Editor

Thu, 28 Nov 2019 14:55:05 +0100

Added a very (stupidly simple) editor to static generator

All it does is let me create new entires, doesn’t allow editor, if I make a mistake I have to start again

and I can’t edit any old filess
