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.

[agapi-kalyptei]

man, i LOVE the rush you get in the days before burning out

Took me a few days but I managed to upgrade a bunch of old code and packages, opened literally hundreds of documentation and troubleshooting tabs (and closed most of them! only about 1152 to go), BUT I managed to get the Heptapod runners to actually build and push docker images on commit, AND it deploys it to my kubernetes cluster.

And yeah I know that someone who just uses some free tier cloud services would take 2.4 minutes to do the same, but I get the extra satisfaction of knowing I can deploy a k8s cluster onto literally any machine that's connected to the internet, with ssl certificates, gitlab, harbor, postgres and w/e. Would be also nice to have an ELK stack or Loki and obviously prometheus+grafana, and backups, but whatever, I'll add those when I have actually something useful to run.

Toying with the idea of making my own private/secure messaging platform but it wouldn't be technically half as competent as Signal; However I still want to make the registration-less, anon ask + private reply platform. Maybe. And the product feature request rating site. And google keep that properly works in Firefox.

Anyway, realistically though I'll start with learning Vue 3 and making the idle counter button app for desktop/android, which I can later port to the web. (No mac/ios builds until someone donates a macbook and $100 for a developer license, which I don't want anyway.) This will start as a button to track routine activities (exercise, water drinking, doing dishes), or a button to click when forced to sit tight and feeling uncomfortable (eg. you can define one button for boring work meetings, one for crowded bus rides, one of insomnia, etc). The app will keep statistics per hour/day/etc. Maybe I'll add sub-buttons with tags like "anxious" "bored" "tired" "in pain" etc. I'm going to use it as a simpler method of journaling and keeping track of health related stuff.

After that I want to extend the app with mini-games that will be all optional, and progressively more engaging. At the lowest end it will be just moving mouse left and right to increase score, with no goal, no upgrades, no story, etc. This is something for me to do when watching a youtube tutorial but feeling too anxious/restless to just sit, and too tired to exercise.

On the other end it will be just whatever games you don't mind killing time with that are still simple and unobtrusive and only worth playing when you're too tired and brain dead to Do Cool Stuff. Maybe some infinite procedurally generated racing with no goals, some sort of platformer or minecraft-like world to just walk around in, without any goals or fighting or death. Or a post-collapse open world where you just pick up trash and demolish leftovers of capitalism. Stardew Valley without time pressure.

I might add flowcharts for ADHD / anxieties, sort of micro-CBT for things that you've already been in therapy for, but need regular reminders. (If the app gets popular it could also have just a these flowcharts contributed from users for download).

Anyway, ideas are easy, good execution is hard, free time is scarce. I hope I get the ball rolling though.

Understanding Docker Playground Online: Your Gateway to Containerization

In the ever-evolving world of software development, containerization has become a pivotal technology, allowing developers to create, deploy, and manage applications in isolated environments. Docker, a leader in this domain, has revolutionized how applications are built and run. For both novices and seasoned developers, mastering Docker is now essential, and one of the best ways to do this is by leveraging an Online Docker Playground. In this article, we will explore the benefits of using such a platform and delve into the Docker Command Line and Basic Docker Commands that form the foundation of containerization.

The Importance of Docker in Modern Development

Docker has gained immense popularity due to its ability to encapsulate applications and their dependencies into containers. These containers are lightweight, portable, and can run consistently across different computing environments, from a developer's local machine to production servers in the cloud. This consistency eliminates the "it works on my machine" problem, which has historically plagued developers.

As a developer, whether you are building microservices, deploying scalable applications, or managing a complex infrastructure, Docker is an indispensable tool. Understanding how to effectively use Docker begins with getting comfortable with the Docker Command Line Interface (CLI) and mastering the Basic Docker Commands.

Learning Docker with an Online Docker Playground

For beginners, diving into Docker can be daunting. The Docker ecosystem is vast, with numerous commands, options, and configurations to learn. This is where an Online Docker Playground comes in handy. An Online Docker Playground provides a sandbox environment where you can practice Docker commands without the need to install Docker locally on your machine. This is particularly useful for those who are just starting and want to experiment without worrying about configuring their local environment.

Using an Online Docker Playground offers several advantages:

Accessibility: You can access the playground from any device with an internet connection, making it easy to practice Docker commands anytime, anywhere.

No Installation Required: Skip the hassle of installing Docker and its dependencies on your local machine. The playground provides a ready-to-use environment.

Safe Experimentation: You can test commands and configurations in a risk-free environment without affecting your local system or production environment.

Immediate Feedback: The playground often includes interactive tutorials that provide instant feedback, helping you learn more effectively.

Getting Started with Docker Command Line

The Docker Command Line Interface (CLI) is the primary tool you'll use to interact with Docker. It's powerful, versatile, and allows you to manage your Docker containers and images with ease. The CLI is where you will issue commands to create, manage, and remove containers, among other tasks.

To begin, let's explore some Basic Docker Commands that you will frequently use in your journey to mastering Docker:

docker run: This command is used to create and start a new container from an image. For example, docker run hello-world pulls the "hello-world" image from Docker Hub and runs it in a new container.

docker ps: To see a list of running containers, use the docker ps command. To view all containers (running and stopped), you can add the -a flag: docker ps -a.

docker images: This command lists all the images stored locally on your machine. It shows details like the repository, tag, image ID, and creation date.

docker pull: To download an image from Docker Hub, use docker pull. For example, docker pull nginx fetches the latest version of the NGINX image from Docker Hub.

docker stop: To stop a running container, use docker stop [container_id]. Replace [container_id] with the actual ID or name of the container you want to stop.

docker rm: Once a container is stopped, you can remove it using docker rm [container_id].

docker rmi: If you want to delete an image from your local storage, use docker rmi [image_id].

Conclusion

Mastering Docker is a crucial skill for modern developers, and utilizing an Online Docker Playground is one of the most effective ways to get started. By practicing Docker Command Line usage and familiarizing yourself with Basic Docker Commands, you can gain the confidence needed to manage complex containerized environments. As you progress, you'll find that Docker not only simplifies the deployment process but also enhances the scalability and reliability of your applications. Dive into Docker today, and unlock the full potential of containerization in your development workflow.

Containerization with Docker and Kubernetes: An Essential Guide

Docker and Kubernetes have emerged as foundational tools for containerization and orchestration in the rapidly evolving landscape of cloud-native technologies. This blog post explores their roles, provides setup guides, and highlights key use cases demonstrating their power and flexibility.

Introduction to Containerization

Containerization is a lightweight alternative to traditional virtualization, enabling applications to run in isolated environments. This approach solves many problems related to environment consistency, application deployment, and scalability. 

Docker: The Containerization Pioneer

What is Docker?

Docker is an open-source platform that automates the deployment of applications inside lightweight, portable containers. It encapsulates an application and its dependencies, ensuring it runs consistently across various environments.

Why Use Docker?

Consistency: Ensures the application behaves the same, regardless of where it is run.

Efficiency: Reduces overhead by sharing the host OS kernel.

Portability: Facilitates seamless movement of applications between development, testing, and production environments.

Setting Up Docker

1. Install Docker:

   - Windows & macOS: Download the Docker Desktop installer from [Docker's official site](https://www.docker.com/products/docker-desktop).

   - Linux: Use the package manager. For example, on Ubuntu:

     sudo apt-get update

     sudo apt-get install docker-ce docker-ce-cli containerd.io

2. Verify Installation:

 docker --version

3. Run Your First Container:

    docker run hello-world

Docker Use Cases

- Microservices: Simplifies the deployment and management of microservice architectures.

- DevOps: Streamlines CI/CD pipelines by providing consistent environments.

- Hybrid Cloud: Enables seamless movement of workloads between on-premises and cloud environments.

Kubernetes: Orchestrating Containers at Scale

What is Kubernetes?

Kubernetes, often abbreviated as K8s, is an open-source platform for automating the deployment, scaling, and operation of containerized applications. It manages clusters of containers, ensuring high availability and scalability.

Why Use Kubernetes?

- Scalability: Automatically scales applications based on demand.

- Self-Healing: Automatically restarts, replaces, and reschedules containers when they fail.

- Service Discovery & Load Balancing: Efficiently balances traffic and discovers services without manual intervention.

Setting Up Kubernetes

1. Install Kubernetes Tools:

   - kubectl: Command-line tool for interacting with Kubernetes clusters.

   - Minikube: Local Kubernetes cluster for development.

   # Install kubectl

   sudo apt-get update

   sudo apt-get install -y kubectl

    Install Minikube

   curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

   chmod +x minikube

   sudo mv minikube /usr/local/bin/

2. Start Minikube:

  minikube start

3. Deploy an Application:

   kubectl create deployment hello-node --image=k8s.gcr.io/echoserver:1.4

   kubectl expose deployment hello-node --type=LoadBalancer --port=8080

   minikube service hello-node

Kubernetes Use Cases

- Complex Applications: Manages applications with multiple, interdependent services.

- CI/CD Pipelines: Enhances automation and reduces the risk of deployment issues.

- Multi-Cloud Deployments: Orchestrates applications across various cloud providers.

Integrating Docker and Kubernetes

While Docker provides the containerization platform, Kubernetes offers robust orchestration capabilities. Together, they form a powerful combination for building, deploying, and managing cloud-native applications.

Example Workflow:

1. Build Docker Image:

   docker build -t my-app .

2. Push to Container Registry:

   docker tag my-app my-repo/my-app

   docker push my-repo/my-app

3. Deploy with Kubernetes:

   kubectl create deployment my-app --image=my-repo/my-app

   kubectl expose deployment my-app --type=LoadBalancer --port=80

Conclusion

Containerization with Docker and Kubernetes revolutionizes how applications are developed, deployed, and managed. By leveraging Docker's simplicity and Kubernetes' powerful orchestration capabilities, organizations can achieve greater agility, scalability, and reliability in their cloud-native journey.

How to Store Images in Container Registries?

Introduction:

Container registries serve as central repositories for storing and managing container images, facilitating seamless deployment across various environments. However, optimizing image storage within these registries requires careful consideration of factors such as scalability, security, and performance. - Docker and Kubernetes Training

Choose the Right Registry:

Selecting the appropriate container registry is the first step towards efficient image storage. Popular options include Docker Hub, Google Container Registry (GCR), Amazon Elastic Container Registry (ECR), and Azure Container Registry (ACR). Evaluate factors such as integration with existing infrastructure, pricing, security features, and geographical distribution to make an informed decision.

Image Tagging Strategy:

Implement a robust tagging strategy to organize and manage container images effectively. Use semantic versioning or timestamp-based tagging to denote image versions and updates clearly. Avoid using generic tags like "latest," as they can lead to ambiguity and inconsistent deployments. - Kubernetes Online Training

Optimize Image Size:

Minimize image size by adhering to best practices such as using lightweight base images, leveraging multi-stage builds, and optimizing Dockerfiles. Removing unnecessary dependencies and layers helps reduce storage requirements and accelerates image pull times during deployment.

Security Considerations:

Prioritize security by implementing access controls, image signing, and vulnerability scanning within the container registry. Restrict image access based on user roles and permissions to prevent unauthorized usage. Regularly scan images for vulnerabilities and apply patches promptly to mitigate potential risks. - Docker Online Training

Automated Builds and CI/CD Integration:

Integrate container registries with continuous integration/continuous deployment (CI/CD) pipelines to automate image builds, testing, and deployment processes. Leverage tools like Jenkins, GitLab CI/CD, or GitHub Actions to streamline workflows and ensure consistent image updates across environments.

Content Trust and Image Signing:

Enable content trust mechanisms such as Docker Content Trust or Notary to ensure image authenticity and integrity. By digitally signing images and verifying signatures during pull operations, organizations can mitigate the risk of tampering and unauthorized modifications.

Data Backup and Disaster Recovery:

Implement robust backup and disaster recovery strategies to safeguard critical container images against data loss or corruption. Regularly backup registry data to redundant storage locations and establish procedures for swift restoration in the event of failures or disasters. - Docker and Kubernetes Online Training

Performance Optimization:

Optimize registry performance by leveraging caching mechanisms, content delivery networks (CDNs), and geo-replication to reduce latency and improve image retrieval speeds. Distribute registry instances across multiple geographical regions to enhance availability and resilience.

Conclusion:

By following best practices such as selecting the right registry, optimizing image size, enforcing security measures, and integrating with CI/CD pipelines, organizations can streamline image management and enhance their containerized deployments without diving into complex coding intricacies.

Version 556

windows

zip

exe

macOS

app

linux

tar.zst

I had an ok week. I fixed some bugs and added a system to force-set filetypes.

You will be asked on update if you want to regenerate some animation thumbnails. The popup explains the decision, I recommend 'yes'.

full changelog

forced filetype

The difference between a zip and an Ugoira and a cbz is not perfectly clear cut. I am happy with the current filetype scanner--and there are a couple more improvements this week--but I'm sure there will always be some fuzziness in the difficult cases. This also applies to some clever other situations, like files that secretly store a zip concatenated after a jpeg. You might want that file to be considered something other than hydrus thinks it technically is.

So, on any file selection, you can now hit right-click->manage->force filetype. You can set any file to be seen as any other file. The changes take affect immediately, are reflected in presentation and system:filetype searches, and the files themselves will be renamed on disk (to aid 'open externally'). The original filetype is remembered, and everything is easily undoable through the same dialog.

Also added is 'system:has forced filetype', under the 'system:file properties' entry, if you'd like to find what you have set one way or the other.

This is experimental, and I don't recommend it for the most casual users, but if you are comfortable, have a play with it. I still need to write better error handling for complete nonsense cases (e.g. calling a webm a krita is probably going to raise an error somewhere), but let me know how you get on.

other highlights

I fixed some dodgy numbers in Mr. Bones (deleted file count) and the file history chart (inbox/archive count). If you have had some whack results here, let me know if things are any better! If they aren't, does changing the search to something more specific than 'all my files'/'system:everything' improve things?

Some new boot errors, mostly related to missing database components, are now handled with nicer dialog prompts, and even interactive console prompts serverside.

I _may_ have fixed/relieved the 'program is hung when restored from minimise to system tray' issue, but I am not confident. If you still have this, let me know how things are now. If you still get a hang, more info on what your client was doing during the minimise would help--I just cannot reproduce this problem reliably.

Thanks to a user who figured out all the build script stuff, the Docker package is now Alpine 3.19. The Docker package should have newer libraries and broader file support.

birthday and year summary

The first non-experimental beta of hydrus was released on December 14th, 2011. We are now going on twelve years.

Like many, I had an imperfect 2023. I've no complaints, but IRL problems from 2022 cut into my free time and energy, and I regret that it impacted my hydrus work time. I had hoped to move some larger projects forward this year, but I was mostly treading water with little features and optimisations. That said, looking at the changelog for the year reveals good progress nonetheless, including: multiple duplicate search and filter speed and accuracy improvements, and the 'one file in this search, the other in this search' system; significant Client API expansions, in good part thanks to a user, including the duplicates system, more page inspections, multiple local file domains, and http headers; new sidecar datatypes and string processing tools; improvements to 'related tags' search; much better transparency support, including 'system:has transparency'; more program stability, particularly with mpv; much much faster tag autocomplete results, and faster tag and file search cancelling; the inc/dec rating service; better file timestamp awareness and full editing capability; the SauceNAO-style image search under 'system:similar files'; blurhashes; more and better system predicate parsing, and natural system predicate parsing in the normal file search input; a background database table delete system that relieves huge jobs like 'delete the PTR'; more accurate Mr. Bones and File History, and both windows now taking any search; and multiple new file formats, like HEIF and gzip and Krita, and thumbnails and full rendering for several like PSD and PDF, again in good part thanks to a user, and then most recently the Ugoira and CBZ work.

I'm truly looking forward to the new year, and I plan to keep working and putting out releases every week. I deeply appreciate the feedback and help over the years. Thank you!

next week

I have only one more week in the year before my Christmas holiday, so I'll just do some simple cleanup and little fixes.

New and Updated RFCs

[new] Add closure-move-bindings RFC

[new] RFC: Include Future and IntoFuture in the 2024 prelude

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

No RFCs issued a call for testing this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Quote of the Week

The Rust mission -- let you write software that's fast and correct, productively -- has never been more alive. So next Rustconf, I plan to celebrate:

All the buffer overflows I didn't create, thanks to Rust

All the unit tests I didn't have to write, thanks to its type system

All the null checks I didn't have to write thanks to Option and Result

All the JS I didn't have to write thanks to WebAssembly

All the impossible states I didn't have to assert "This can never actually happen"

All the JSON field keys I didn't have to manually type in thanks to Serde

All the missing SQL column bugs I caught at compiletime thanks to Diesel

All the race conditions I never had to worry about thanks to the borrow checker

All the connections I can accept concurrently thanks to Tokio

All the formatting comments I didn't have to leave on PRs thanks to Rustfmt

All the performance footguns I didn't create thanks to Clippy

– Adam Chalmers in their RustConf 2023 recap

Thanks to robin for the suggestion!

Please submit quotes and vote for next week!

Once your Docker image is ready, push it to a…

Energy dashboard missing some bars Recently I acquired a sensor for the electricity meter. The sensor page is in PT, but is a tasmota that was adjusted to the meters used in Portugal. It is connected through MQTT and I have the values in Home Assistant and the database: However, the energy dashboard has a strange behaviour: There are mentions of similar issues, but all appear to fix themselves after one update or by changing the browser. HomeAssistant is being deployed in an RPI4 with the following docker-compose: version: '3' services: homeassistant: container_name: homeassistant image: "ghcr.io/home-assistant/home-assistant:stable" restart: unless-stopped environment: - TZ=Europe/Lisbon volumes: - ./config/:/config - /etc/localtime:/etc/localtime:ro privileged: true network_mode: host depends_on: - mosquitto - mariadb - influxdb mosquitto: image: eclipse-mosquitto container_name: mosquitto volumes: - ./mosquitto:/mosquitto restart: unless-stopped network_mode: host mariadb: container_name: mariadb image: mariadb restart: unless-stopped ports: - "13306:3306/tcp" # So we can access the WebUI environment: - TZ=Europe/Lisbon - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD} - MYSQL_DATABASE=${MYSQL_HA_DATABASE} - MYSQL_USER=${MYSQL_HA_USER} - MYSQL_PASSWORD=${MYSQL_HA_PASSWORD} volumes: - ./mariadb/data:/var/lib/mysql - ./mariadb/config/:/etc/mysql/conf.d influxdb: container_name: influxdb image: influxdb restart: unless-stopped ports: - "8086:8086/tcp" # So we can access the WebUI environment: - TZ=Europe/Lisbon - DOCKER_INFLUXDB_INIT_MODE=setup - DOCKER_INFLUXDB_INIT_USERNAME=${INFLUXDB_USER} - DOCKER_INFLUXDB_INIT_PASSWORD=${INFLUXDB_PASSWORD} - DOCKER_INFLUXDB_INIT_ORG=${INFLUXDB_ORG} - DOCKER_INFLUXDB_INIT_BUCKET=${INFLUXDB_BUCKET} volumes: - ./influxdb/data:/var/lib/influxdb2 - ./influxdb/config/:/etc/influxdb2 ulimits: nofile: soft: 32768 hard: 32768 And the configuration file for home assistant is the following: # Loads default set of integrations. Do not remove. default_config: # Text to speech tts: - platform: google_translate automation: !include automations.yaml script: !include scripts.yaml scene: !include scenes.yaml http: use_x_forwarded_for: true trusted_proxies: - 127.0.0.1 - ::1 - 192.168.1.0/24 recorder: db_url: !secret mariadb purge_keep_days: 10 # default history: influxdb: api_version: 2 ssl: false host: 127.0.0.1 port: 8086 token: !secret influxdb_token organization: !secret influx_org bucket: homeassistant tags: source: HomeAssistant tags_attributes: - friendly_name default_measurement: units ignore_attributes: - icon exclude: # Customise to fit your needs entities: - zone.home domains: - persistent_notification - person Since the sensor values are in the database, I don’t think the issue is in the deployment. I also have no errors in the logs, nor issues in the statistics dev menu.
