10 Fandoms, 10 Characters, 10 Tags

Thank you to @sinvulkt for the tag :D Let's go...

Rey (Star Wars Sequels)

Rey is at this stage by some way the character I've spilled the most ink over, specifically a post-TLJ Rey Nobody. I love her curiosity, her loyalty and that core of wounded anger. I want her to be happy and kick baddies in the head.

2. Ikrie (Horizon: Forbidden West)

Shape a woman out of abandonment issues and give her a spear. With so little screentime, she's such a fully-formed character, tough yet vulnerable, flitting between rambunctious and melancholy, and "I never cared about the Werak" cuts me to the bone each time.

3. Shiban Khan (The Horus Heresy)

Broken down and built back up, two or three times over. It's heartbreaking to see how he falls into bitterness over the course of the Heresy, and then glorious to see him rise again and become one of his Legion's greatest heroes.

4. Barristan Selmy (A Song of Ice and Fire)

It's fascinating to watch a character shaking off decades of swallowed doubts, forced to evolve by events. If we ever get The Winds of Winter, I hope his progression continues.

5. Keeve Trennis (Star Wars: The High Republic)

Adorable, great haircut, bold and passionate yet warring with impostor syndrome. Also swears like a Corellian kriffing docker, and she has a neat splitting saberstaff. What's not to love?

6. Theoden (The Lord of the Rings)

It still amazes me upon rewatching The Two Towers that Bernard Hill doesn't just walk off with the whole film, his performance is so magnificent. I don't think there's really anything I can add which hasn't been said already.

7. Caitlyn Kirramen (Arcane)

Lawful good, beginning to realise just how how questionable the good of the law she serves is. Her evolving dynamic with Vi is great, she's tougher than those around her expect and of course, she's so very very pretty.

8. Stephen Maturin (Master and Commander)

A canny spy who is nonetheless perpetually baffled and exasperated by the nautical world he has inveigled himself into. Also a thorough nerd.

9. Mahit Dzmare & Three Seagrass (A Memory Called Empire & A Desolation Called Peace)

Cheating a little in part because I couldn't find a solo pic of Mahit that wasn't AI-generated and also because I love them so very much, your honour. These little bundles of anxiety and constant second-guessing, pitched into events far more massive and momentous than anything either had imagined. And they have moments of intimacy to eat rocks for.

10. Yrica Quell (Star Wars: Alphabet Squadron)

You can fit so much guilt and conflict in this bad girl. Quell has arguably the most fascinating "Imperial defector" arc in all the Star Wars media I've read, as she undergoes this evolving moral struggle across her trilogy.

yes! kill spotify & co! literally the worst thing that happened to music since the whole major label monopoly debacle

if you wanna invest a little more resources and brain juice, you can even set up your own spotify-like server to stream your stuff to your devices even if you're away from home - especially helpful if your music library gets too big to comfortably fit on your phone storage

i use an amalgamation of old pc parts, debian headless, the lsio swag docker image for connectivity, beets for tagging, and navidrome as the actual library/streaming service, feishin as my desktop music player (fantastic ui and very similar to spotify!) and symfonium for my android devices (which is the only thing not free and open source, apart from the hardware and my domain name, but it's a very good player, and it's only like 9€ one-time after a generous trial) - it took weeks to set it all up since i started from a place of very little knowledge about how servers work etc, but the amount of effort i put into it makes me all the more proud of the finished thing, and i learned a LOT about how the internet works on a technical level! <3

here's a list of programs/sites/whatever that were helpful to me when i was moving away from using spotify & back to downloading music:

soulseek - peer to peer downloading program, has most music you'd want. there's "rules" to it though and the UI is a little confusing, but you can figure it out. there's tutorials. i believe in you

cobalt.tools, ytiz.xyz, yt-dlp - mp3 downloaders, for the songs that you can't find on soulseek

musicbee - music player, extremely customiseable. reminds me of when i used itunes back in the day. has a lot of good features, including syncing music over to your phone

lastfm & listenbrainz - sites that keep track of your listening stats. i'd recommend this even if you still choose to use a music streaming service

syncedlyrics - cmd thing that gets you timed song lyrics, like the ones spotify has. there's no UI but it's easy enough to use. just grab the lyrics and timestamps it spits out and paste it into musicbee

music presence - program that shows what song you're listening to in your discord status, in case you use discord and enjoy the thought of other people seeing what you're listening to, which i do for some reason

i'm not going to lie to you and say that switching away from spotify/streaming services is an effortless task, it took me half a whole day of nonstop Work to get all my music downloaded and sorted out, but i will say that it was worth it!! and you should do it 👍 if you want to

🔍 Correlating Mirantis Kubernetes Engine (MKE) Symptoms with Components

In a complex cloud-native environment, understanding the root cause of performance or availability issues can be challenging. With Mirantis Kubernetes Engine (MKE), it becomes crucial to correlate observed symptoms with the appropriate components in the architecture to ensure effective troubleshooting and resolution.

This blog explores how to link common operational symptoms with the specific MKE components responsible for them, providing a strategic lens for diagnosis and action.

🚦 Why Symptom Correlation Matters

MKE is built on top of Kubernetes but introduces additional layers such as secure registries, load balancing, high availability configurations, and authentication integrations. When a problem arises—whether it's performance degradation, failure to schedule workloads, or API timeouts—knowing which component is likely involved can significantly reduce downtime and guesswork.

🧩 MKE Architecture – A Quick Look

Key components to keep in mind:

UCP (Universal Control Plane) – MKE's management and orchestration layer.

DTR (Docker Trusted Registry) – Secure container image management.

Kubernetes Control Plane – Scheduler, API server, etcd, controller manager.

Worker Nodes – Where workloads actually run.

Networking Components – CNI plugins, ingress controllers, and service proxies.

Authentication Systems – LDAP, SSO integrations, RBAC.

🔍 Common Symptoms & Component Correlation

1. Slow or Failed Container Scheduling

Likely Components:

Kubernetes Scheduler

Etcd (if etcd latency is high)

Worker Nodes (resource constraints)

Possible Causes:

Resource exhaustion (CPU, Memory)

Taints/tolerations misconfiguration

Scheduler throttling

2. API Server Timeouts or Failures

Likely Components:

UCP API Layer

Kubernetes API Server

Network/Ingress layer

Possible Causes:

API overload

Control plane resource bottlenecks

Misconfigured ingress or firewall rules

3. Unable to Pull Images or Image Push Fails

Likely Components:

Docker Trusted Registry (DTR)

Network

Authentication

Possible Causes:

Expired or revoked credentials

DTR storage issues

Misconfigured image policies or tags

4. Pod-to-Pod Communication Failures

Likely Components:

CNI Plugin

kube-proxy / CoreDNS

Node Network

Possible Causes:

Misconfigured network policies

DNS resolution failures

Broken overlay network

5. Dashboard or UCP UI Inaccessibility

Likely Components:

UCP Manager Nodes

Load Balancer

TLS Certificates

Possible Causes:

Expired certs

Network routing or port mapping issues

Broken proxy configuration

6. Persistent Volume Not Mounting

Likely Components:

CSI Driver

Worker Node

Kubernetes Controller Manager

Possible Causes:

Incorrect storage class or access mode

Unavailable storage backend

Permissions issue at node level

🛠️ Best Practices for Effective Correlation

Use centralized monitoring tools like Prometheus and Grafana integrated with MKE.

Set up logging and alerting for UCP, DTR, and Kubernetes components.

Maintain a component-symptom matrix for your team to reference during incidents.

Perform regular health checks of nodes, registries, and control plane endpoints.

Use mirantis support bundles and diagnostics tools to collect insights systematically.

✅ Final Thoughts

MKE delivers powerful Kubernetes orchestration with enterprise-grade security and scalability. But with great power comes the need for operational clarity. By correlating observed symptoms with the responsible components, administrators can reduce troubleshooting time and prevent system-wide disruptions.

Stay proactive. Know your architecture. Correlate smartly.

52013l4 in Modern Tech: Use Cases and Applications

In a technology-driven world, identifiers and codes are more than just strings—they define systems, guide processes, and structure workflows. One such code gaining prominence across various IT sectors is 52013l4. Whether it’s in cloud services, networking configurations, firmware updates, or application builds, 52013l4 has found its way into many modern technological environments. This article will explore the diverse use cases and applications of 52013l4, explaining where it fits in today’s digital ecosystem and why developers, engineers, and system administrators should be aware of its implications.

Why 52013l4 Matters in Modern Tech

In the past, loosely defined build codes or undocumented system identifiers led to chaos in large-scale environments. Modern software engineering emphasizes observability, reproducibility, and modularization. Codes like 52013l4:

Help standardize complex infrastructure.

Enable cross-team communication in enterprises.

Create a transparent map of configuration-to-performance relationships.

Thus, 52013l4 isn’t just a technical detail—it’s a tool for governance in scalable, distributed systems.

Use Case 1: Cloud Infrastructure and Virtualization

In cloud environments, maintaining structured builds and ensuring compatibility between microservices is crucial. 52013l4 may be used to:

Tag versions of container images (like Docker or Kubernetes builds).

Mark configurations for network load balancers operating at Layer 4.

Denote system updates in CI/CD pipelines.

Cloud providers like AWS, Azure, or GCP often reference such codes internally. When managing firewall rules, security groups, or deployment scripts, engineers might encounter a 52013l4 identifier.

Use Case 2: Networking and Transport Layer Monitoring

Given its likely relation to Layer 4, 52013l4 becomes relevant in scenarios involving:

Firewall configuration: Specifying allowed or blocked TCP/UDP ports.

Intrusion detection systems (IDS): Tracking abnormal packet flows using rules tied to 52013l4 versions.

Network troubleshooting: Tagging specific error conditions or performance data by Layer 4 function.

For example, a DevOps team might use 52013l4 as a keyword to trace problems in TCP connections that align with a specific build or configuration version.

Use Case 3: Firmware and IoT Devices

In embedded systems or Internet of Things (IoT) environments, firmware must be tightly versioned and managed. 52013l4 could:

Act as a firmware version ID deployed across a fleet of devices.

Trigger a specific set of configurations related to security or communication.

Identify rollback points during over-the-air (OTA) updates.

A smart home system, for instance, might roll out firmware_52013l4.bin to thermostats or sensors, ensuring compatibility and stable transport-layer communication.

Use Case 4: Software Development and Release Management

Developers often rely on versioning codes to track software releases, particularly when integrating network communication features. In this domain, 52013l4 might be used to:

Tag milestones in feature development (especially for APIs or sockets).

Mark integration tests that focus on Layer 4 data flow.

Coordinate with other teams (QA, security) based on shared identifiers like 52013l4.

Use Case 5: Cybersecurity and Threat Management

Security engineers use identifiers like 52013l4 to define threat profiles or update logs. For instance:

A SIEM tool might generate an alert tagged as 52013l4 to highlight repeated TCP SYN floods.

Security patches may address vulnerabilities discovered in the 52013l4 release version.

An organization’s SOC (Security Operations Center) could use 52013l4 in internal documentation when referencing a Layer 4 anomaly.

By organizing security incidents by version or layer, organizations improve incident response times and root cause analysis.

Use Case 6: Testing and Quality Assurance

QA engineers frequently simulate different network scenarios and need clear identifiers to catalog results. Here’s how 52013l4 can be applied:

In test automation tools, it helps define a specific test scenario.

Load-testing tools like Apache JMeter might reference 52013l4 configurations for transport-level stress testing.

Bug-tracking software may log issues under the 52013l4 build to isolate issues during regression testing.

What is 52013l4?

At its core, 52013l4 is an identifier, potentially used in system architecture, internal documentation, or as a versioning label in layered networking systems. Its format suggests a structured sequence: “52013” might represent a version code, build date, or feature reference, while “l4” is widely interpreted as Layer 4 of the OSI Model — the Transport Layer.Because of this association, 52013l4 is often seen in contexts that involve network communication, protocol configuration (e.g., TCP/UDP), or system behavior tracking in distributed computing.

FAQs About 52013l4 Applications

Q1: What kind of systems use 52013l4? Ans. 52013l4 is commonly used in cloud computing, networking hardware, application development environments, and firmware systems. It's particularly relevant in Layer 4 monitoring and version tracking.

Q2: Is 52013l4 an open standard? Ans. No, 52013l4 is not a formal standard like HTTP or ISO. It’s more likely an internal or semi-standardized identifier used in technical implementations.

Q3: Can I change or remove 52013l4 from my system? Ans. Only if you fully understand its purpose. Arbitrarily removing references to 52013l4 without context can break dependencies or configurations.

Conclusion

As modern technology systems grow in complexity, having clear identifiers like 52013l4 ensures smooth operation, reliable communication, and maintainable infrastructures. From cloud orchestration to embedded firmware, 52013l4 plays a quiet but critical role in linking performance, security, and development efforts. Understanding its uses and applying it strategically can streamline operations, improve response times, and enhance collaboration across your technical teams.

Quote of the Week

Well, the answer is basically yes. Our firmware is all Rust. Every component of our autonomy stack is Rust. Our app is 50% in Rust. And, our visualization tools are in Rust. Our production tools are in rust. The production QC software, which we ship to China, is in rust. Our internal websites are in rust. It's rust all over. We’ve drank the Rust Kool-Aid. In fact, there is no Python installed on the robots. This is not to dis Python at all, but it’s just simply not there.

We use Python for neural network training. But Python is boxed to that. Everything else is Rust. And, the advantage of using Rust exponentially builds up.

🚀 Container Adoption Boot Camp for Developers: Fast-Track Your Journey into Containerization

In today’s DevOps-driven world, containerization is no longer a buzzword—it’s a fundamental skill for modern developers. Whether you're building microservices, deploying to Kubernetes, or simply looking to streamline your development workflow, containers are at the heart of it all.

That’s why we created the Container Adoption Boot Camp for Developers—a focused, hands-on training program designed to take you from container curious to container confident.

🧠 Why Containers Matter for Developers

Containers bring consistency, speed, and scalability to your development and deployment process. Imagine a world where:

Your app works exactly the same on your machine as it does in staging or production.

You can spin up dev environments in seconds.

You can ship features faster with fewer bugs.

That’s the power of containerization—and our boot camp helps you unlock it.

🎯 What You’ll Learn

Our boot camp is developer-first and practical by design. Here’s a taste of what we cover:

✅ Container Fundamentals

What are containers? Why do they matter?

Images vs containers vs registries

Comparison: Docker vs Podman

✅ Building Your First Container

Creating and optimizing Dockerfiles

Managing multi-stage builds

Deploying Containers on AWS ECS with Fargate

Introduction

Amazon Elastic Container Service (ECS) with AWS Fargate enables developers to deploy and manage containers without managing the underlying infrastructure. Fargate eliminates the need to provision or scale EC2 instances, providing a serverless approach to containerized applications.

This guide walks through deploying a containerized application on AWS ECS with Fargate using AWS CLI, Terraform, or the AWS Management Console.

1. Understanding AWS ECS and Fargate

✅ What is AWS ECS?

Amazon ECS (Elastic Container Service) is a fully managed container orchestration service that allows running Docker containers on AWS.

✅ What is AWS Fargate?

AWS Fargate is a serverless compute engine for ECS that removes the need to manage EC2 instances, providing:

Automatic scaling

Per-second billing

Enhanced security (isolation at the task level)

Reduced operational overhead

✅ Why Choose ECS with Fargate?

✔ No need to manage EC2 instances ✔ Pay only for the resources your containers consume ✔ Simplified networking and security ✔ Seamless integration with AWS services (CloudWatch, IAM, ALB)

2. Prerequisites

Before deploying, ensure you have:

AWS Account with permissions for ECS, Fargate, IAM, and VPC

AWS CLI installed and configured

Docker installed to build container images

An existing ECR (Elastic Container Registry) repository

3. Steps to Deploy Containers on AWS ECS with Fargate

Step 1: Create a Dockerized Application

First, create a simple Dockerfile for a Node.js or Python application.

Example: Node.js DockerfiledockerfileFROM node:16-alpine WORKDIR /app COPY package.json . RUN npm install COPY . . CMD ["node", "server.js"] EXPOSE 3000

Build and push the image to AWS ECR:shaws ecr create-repository --repository-name my-app docker build -t my-app . docker tag my-app:latest <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest aws ecr get-login-password --region <REGION> | docker login --username AWS --password-stdin <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com docker push <AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest

Step 2: Create an ECS Cluster

Use the AWS CLI to create a cluster:shaws ecs create-cluster --cluster-name my-cluster

Or use Terraform:hclresource "aws_ecs_cluster" "my_cluster" { name = "my-cluster" }

Step 3: Define a Task Definition for Fargate

The task definition specifies how the container runs.

Create a task-definition.js{ "family": "my-task", "networkMode": "awsvpc", "executionRoleArn": "arn:aws:iam::<AWS_ACCOUNT_ID>:role/ecsTaskExecutionRole", "cpu": "512", "memory": "1024", "requiresCompatibilities": ["FARGATE"], "containerDefinitions": [ { "name": "my-container", "image": "<AWS_ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/my-app:latest", "portMappings": [{"containerPort": 3000, "hostPort": 3000}], "essential": true } ] }

Register the task definition:shaws ecs register-task-definition --cli-input-json file://task-definition.json

Step 4: Create an ECS Service

Use AWS CLI:shaws ecs create-service --cluster my-cluster --service-name my-service --task-definition my-task --desired-count 1 --launch-type FARGATE --network-configuration "awsvpcConfiguration={subnets=[subnet-xyz],securityGroups=[sg-xyz],assignPublicIp=\"ENABLED\"}"

Or Terraform:hclresource "aws_ecs_service" "my_service" { name = "my-service" cluster = aws_ecs_cluster.my_cluster.id task_definition = aws_ecs_task_definition.my_task.arn desired_count = 1 launch_type = "FARGATE" network_configuration { subnets = ["subnet-xyz"] security_groups = ["sg-xyz"] assign_public_ip = true } }

Step 5: Configure a Load Balancer (Optional)

If the service needs internet access, configure an Application Load Balancer (ALB).

Create an ALB in your VPC.

Add an ECS service to the target group.

Configure a listener rule for routing traffic.

4. Monitoring & Scaling

🔹 Monitor ECS Service

Use AWS CloudWatch to monitor logs and performance.shaws logs describe-log-groups

🔹 Auto Scaling ECS Tasks

Configure an Auto Scaling Policy:sh aws application-autoscaling register-scalable-target \ --service-namespace ecs \ --scalable-dimension ecs:service:DesiredCount \ --resource-id service/my-cluster/my-service \ --min-capacity 1 \ --max-capacity 5

5. Cleaning Up Resources

After testing, clean up resources to avoid unnecessary charges.shaws ecs delete-service --cluster my-cluster --service my-service --force aws ecs delete-cluster --cluster my-cluster aws ecr delete-repository --repository-name my-app --force

Conclusion

AWS ECS with Fargate simplifies container deployment by eliminating the need to manage servers. By following this guide, you can deploy scalable, cost-efficient, and secure applications using serverless containers.
