Building a Privacy-First Developer Collaboration Hub

Wed, 23 Jul 2025 08:10:10 +0100

We're living in an era where our most sensitive thoughts, code snippets, and project documentation are scattered across proprietary platforms that treat our data as their product. Every time you paste a code snippet into Notion, jot down API keys in Apple Notes, or share documentation through Google Docs, you're essentially handing over your intellectual property to corporations that monetize your information. At least that is what I'm feeling, so there is no evidences. Just feeling.

Production-Ready n8n on AWS

Thu, 17 Jul 2025 10:10:10 +0100

That will be another microblog-style post about self-hosting on AWS. This time, let's talk about n8n - the workflow automation tool that's been gaining traction in the no-code/low-code world. After successfully deploying GoToSocial on Lightsail (which you can read about here), I decided to tackle something more useful: a production-ready n8n setup that doesn't break the bank.

Why n8n?

n8n is an open-source workflow automation platform that lets you connect different services and APIs. Think Zapier, but self-hosted and with more control. Perfect for automating repetitive tasks, data synchronization, or building complex integrations between your tools.

S3 Notifications as Webhooks for Automation

Tue, 08 Jul 2025 14:10:10 +0100

Hey there, my friends!

I've been working on automating various workflows lately, and let me tell you - I stumbled upon something that completely changed how I think about event-driven automation. Do you remember when I wrote about setting up automated deployments? Well, this time I want to share something even more powerful: using S3 notifications as webhooks for automation.

So here's the story. A few weeks ago, I was dealing with a client who needed to process uploaded files automatically. The traditional approach? Polling S3 buckets every few minutes. Not elegant, not efficient, and definitely not what I'd call a modern solution. That's when I realized - why not use S3 notifications as webhooks? And that is great, to be honest.

The standard - S3 IAM Policies

Tue, 24 Jun 2025 08:10:10 +0100

In the previous post, we explored S3 Access Control Lists (ACLs) and learned why AWS recommends disabling them for most modern use cases. Now it's time to dive into the proper way of securing your S3 buckets: IAM policies and bucket policies.

Unlike ACLs, which are considered legacy and can become operationally chaotic, IAM policies offer centralized, scalable, and auditable access management. They're the foundation of modern AWS security architecture and the tool you should reach for when securing your S3 resources.

How to serve API for humans?

Mon, 16 Jun 2025 09:10:10 +0100

In today's digital landscape, serving APIs has become increasingly challenging. The task of exposing data and functionality to legitimate users has evolved into a complex battle against automated attacks, aggressive crawlers, and misguided AI training attempts.

The challenge isn't just technical—it's philosophical.

How do you distinguish between legitimate automation (which powers the modern web) and malicious bots that drain resources and compromise security?

How do you balance accessibility with protection, especially when dealing with rate limiting, bot detection, and content delivery networks like Cloudflare? This post explores the real-world challenges of maintaining APIs that serve humans while fighting with army of automated requests that seem determined to treat every endpoint as their personal data source.

Setup GoToSocial on AWS Lightsail

Wed, 04 Jun 2025 13:00:10 +0100

That will be a short microblog-style post. As you may know AWS Community Builders, as part of the program benefits are receiving 500$ per year of AWS Cloud credits. Seems a lot, however, domain name registration is excluded, also based on on-demand pricing, 500$ is ok for test ideas, or writing content. Not very good, for long-running services different from S3. However, some time ago I thought about running software on VMs. Not inside containers just as binary. So, why not to use Lightsail? It's simple, even too simple. Thankfully it has, a stable low price, especially if we decide to go with IPv6.

Understand S3 ACL

Tue, 27 May 2025 09:10:10 +0100

Recently you were able to read. about S3 security, and methods of avoiding common misconfiguration with the usage of standard and well-known tools.

The fact that AWS offers a set of access control mechanisms designed to protect S3 resources, including:

Access Control Lists (ACLs)
Identity and Access Management (IAM) policies
S3 Access Points
Multi-Region Access Points
signed URL

This article provides a comprehensive guide to understanding and implementing these mechanisms, highlighting potential misconfigurations that can lead to security vulnerabilities and offer practical guidance on using Terraform for building our secure infrastructure-as-code deployments.

How to secure your S3 bucket by default?

Tue, 29 Apr 2025 14:00:10 +0100

In September this year, I will officially mark 10 years in the IT box. For most of my professional life, I was focused on system administration, automation, DevOps, and a bit of public/hybrid cloud. There was always security, but rather a nice-to-have topic, not the main pillar. Some time ago I decided, that I would try to focus more on privacy and information security, especially now in an era of AI, Vibe Coding, and new hyper-personalized ads idea. What does it mean for you, my friends? You will find more content about securing your workload, networks, and app here. Also from time to time, I will post some notes from my self-hosting journey and attempts to avoid big-tech solutions. After this long intro, let's focus on today's topic - S3 security.

Umami for free?

Mon, 14 Apr 2025 10:10:10 +0100

As you may already know, or not. I'm self-hosting a view apps, where it doesn't mean home-labbing them. My flat wasn't designed to have network cables in all rooms, and storing more units than Synology NAS, HomeAssistant, RasbberyPi and Router on a tiny Ikea shelf could be a dangerous situation. That is why I'm not using my mini-pc as a homelab anymore.

In the beginning, I moved a lot of my services to Hetzner (take a look at previous posts). Now after a while, I started thinking about making more for less. During the vibe coding wave, I learned how to use Supabase and Vercel. Then I started thinking about one crazy thing.

Bootstrap cluster with FluxCD

Tue, 08 Apr 2025 10:10:10 +0100

That is the next iteration of the "5 AM Club" Kubernetes migration. As you can remember from other entries published in this series, I started playing with Kubernetes daily. Not on a daily basis, but literally every single day. To be honest, I'm pretty happy with the results. However, my plan has one challenge, that requires to be solved. Build time was long ~15 minutes every day, and sometimes ESO operator faced an issue regarding using kustomize for Helm-based deployment. And just due to random constraints, I wanted to use one tool for bootstrapping a cluster.

External Secret Operator with Doppler

Sat, 22 Feb 2025 10:10:10 +0100

Last time we configured our cluster step by step maybe without public code yet, but someday I will publish it. Probably when it will be smooth enough to share. Nevertheless, we have a working cluster. Today I will focus on connecting the External Secret Operator with Doppler. So let's introduce today's stars.

External Secret Operator

External Secrets Operator is a Kubernetes operator that Integrates external secret management systems like AWS Secrets Manager, HashiCorp Vault, Google Secrets Manager, Azure Key Vault, IBM Cloud Secrets Manager, CyberArk Conjur, Pulumi ESC and many more. The operator reads information from external APIs and automatically inject the values into a Kubernetes Secret.

Again self-hosting! on k3s

Thu, 06 Feb 2025 10:10:10 +0100

Over some time I was really happy with my podman + ansible setup. It was great, but do you know what wasn’t such great? Deployment rollbacks. It all started with linkwarden. On my miniflux, I received a notification - that a new minor release is ready.

You can use GitHub repos as RSS links and received notification about new releases. If you're using miniflux just past https://github.com/ansible/ansible/releases.atom

Let's say version 2.8.0. When the time came, I just changed my variable and executed ansible-playbook command. Then after 3 minutes, my uptime-kuma started screaming, and saying that my app was dead. Initially, I ignored that, due to my experience with podman. During the service restart it makes an app unavailable, then downloads the new image and tries to run it. If the package is big, it could take a while. It wasn't great, but that is what could be acceptable for self-hosting service. Unfortunately, the main problem was with something different. Maintainers of Linkwarden sometimes inform users about a new release, however, it's only delivered as an rpm/deb package. The container image could be still in the building, or the building process could fail. It doesn't matter, sometimes my typo could occur as well. Then podman can't handle that, nor Ansible as it just restarts the service. Podman on another hand just stops service and does not roll back to the old version automatically. So sometimes it becomes annoying as I need to log into the server with ssh and manually fix it. That is why I decided to switch to some Kubernetes distribution.

Self-hosting with Podman

Thu, 30 Jan 2025 10:10:10 +0100

I've been a self-hoster for a while. The adventure started with regular mani-pc manufactured by HP. 32G of RAM, Intel gen 10, and 1T HDD drive. However, as long as it was a great experience at the beginning, with time it became a challenge. My stack was built with portainer and a bunch of docker-compose files. It leads to specific issues: with portainer, you don't own the Compose files, they are living inside your tool, but nowhere on the filesystem or git repo.

OneDev on ECS

Sun, 15 Sep 2024 08:00:10 +0100

At the beginning of September, I saw a post from Johannes Koch about self-hosting CodeCommit alternative. Then I realized, that I'm using my home, not such a popular, but very nice and solid git repository system. To be more precise, much more than a git server. Let's welcome OneDev.

Git server with CI/CD, kanban, and packages.

They also support repo tags, and groups like GitLab. The project is also very resource-friendly, and I've been using it for a while on my home server.

Information flow

Mon, 26 Aug 2024 10:10:10 +0100

This post will be different, than usual. It will be soft, flexible, and with late summer vibes. Please stop coding, deploying, or whatever is important you're doing. That will be the most helpful post you will read today! Let's talk about being old, or more correctly about seniority. What will distinguish you as a person with 10 years of experience in your job with newcomers with 6 months? Probably first things that will come to your mind will be:

Meetings on demand

Wed, 24 Jul 2024 10:10:10 +0100

Yesterday I decided to solve another, probably non-existent problem. So for quite a long time, I was looking for a solution that would allow me to schedule meetings with friends, family, and clients (the custom domain looks very professional). Most of them are paid every month. Which in my case is not a very cost-effective solution, if I have one meeting per month, sometimes two. Also let's assume, that being an AI learning material for Google, or Zoom isn't my dream position.

Install Keycloak on ECS

Thu, 20 Jun 2024 10:10:10 +0100

If you have read my latest post about accessing RHEL in the cloud, you may notice that we’re accessing the cockpit console, via SSM Session manager port forwarding. That’s not an ideal solution. I’m not talking in bed, it’s just not ideal(but cheap). Today I realised that using Amazon WorkSpaces Secure Browser could be interesting, and fun as well.

Unfortunately, this solution required an Identity Provider, which can serve us with SAML 2.0. The problem is, that most of the providers like Okta or Ping, are enterprise-oriented, and you can’t play with them easily. Of course, you can request a free trial, but it’s 30 days only, and there is no single-user account.

Manage my cheap TLD with Route53

Sun, 16 Jun 2024 10:10:10 +0100

While writing a post about setting up Keycloak, which should be live this month(it's a bit harder, than I thought), I decided that it would be great to use my custom domain and play with it as well. As having sso.3sky.in looks cool, also unexpectedly it’s quite cheap. But why do I need it? It’s like 10$ per domain. Yes and no. One of the Community Builder program benefits is a voucher for 500$ which can be used within a year, on AWS services. On Route53 as well, but not on domains. After a short discussion on Slack with other builders, I realized that the cheapest method is to buy a domain wherever we want to, and then delegate it to Route53, as this cost is covered by the program. Sounds like a plan right? So how to do it? First please read this docs, then let’s try to do it with AWS CDK.

rhel on cloud

Thu, 23 May 2024 10:10:10 +0100

Let’s talk about basic IT operations included in the everyday tasks range. For example, accessing VMs. As you may realize (or not) - not everyone is using immutable infrastructure. Especially when their core business isn’t IT, and they are a bit bigger than 2-pizza team. That is why today we will talk about accessing the console of Red Hat Enterprise Linux 9.3 in AWS Cloud. I will show you the 3 most useful methods - in my opinion; there are no statistics.

DNS as code

Mon, 20 May 2024 10:10:10 +0100

Looks like I have 10 days to create 2 blog posts. To be open, it’s another attempt to become a creator, who makes at least 12 posts per year. Also, I decided, to make my write-ups a bit shorter and focused on one particular topic. That is why, today I will show you how to migrate existing Cloudflare configuration into OpenTofu manifests and make it even more cool with Scalr.

For context, I’m the owner of 3 domains, where one is used for my home lab. What does that it mean? I like to access my services without VPN, from anywhere in the world. Hopefully, Cloudflare provides a solution called tunnels. It could be used for exposing private endpoints/services directly on the internet, without setting up static IP(for example my ISP requires an additional fee for that), also we can easily add multiple “data centers”, for example, NUC under our desk, home NAS, or regular server in your parent's basement.

EDA for AWS operations

Tue, 19 Mar 2024 10:10:10 +0100

Great that you're here. Today, I will write a bit about Event-Driven Ansible and its possibilities for improving the operational efficiency of our AWS environment. But wait, what does it mean by Event-Driven Ansible? My favorite sentence from the documentation is "EDA provides a way of codifying operational logic," so in short words, we can code logic for responding to different events. For example, we can trigger playbook execution with Lambdas make our self-service process a bit more ops-oriented, or introduce ChatOps.

Local automation

Thu, 29 Feb 2024 10:10:10 +0100

Once again I have a goal, write every month at least one article. Sounds easy, but unfortunately for me, it is not. The idea behind this blog is to write content that will be helpful for me(and hopefully for my readers as well). For example, when I need basic Nginx configuration I used to open this post from 2021. Now I’m older a bit, so I decided to switch once again to Doom Emacs(?!!) and start writing my own code/config snippets. As it also can be useful, probably I will write about it someday.

2023 as AWS Community Builder

Sun, 21 Jan 2024 10:10:10 +0100

It's the 3rd week of January 2024. The Community Builder form for the current year is probably already closed, right? Ah, it's not true. It will be closed on the 27th of January, so you still have some time - 5 days. If you need a TLDR, go and apply as fast as possible! Do it now! If you've already applied, I have some stories to share or rather an extended 2023 summary. Please treat this as a possible path; I think you can do it better.

What is the best `as Code` tool in 2023?

Mon, 24 Jul 2023 10:10:10 +0100

Based on the success of my latest article (CHATGPT!), I've decided to continue in that direction by creating shorter and more user-friendly content. Today, I have some thoughts and feelings to share about a complex topic. Recently, I was asked to prepare a sample infrastructure for an OKD cluster from scratch, without pre-built templates. I first used AWS CDK, then rewrote it to Pulumi, and finally to cdktf. You may wonder why I made these changes, and the answer is simple: I really enjoy my job!

Top 5 ChatGPT use cases in AWS Solution Architecture role

Wed, 28 Jun 2023 10:10:10 +0100

Hey there, my friends! Today, I want to share with you the top 5 use cases of ChatGPT in my daily job. But before we dive in, let me tell you a little story. Recently, I made the switch from Obsidian to Logseq, for note-taking, and it got me into the habit of preferring shorter form in general. So, let's get straight to the point and explore how ChatGPT can help us save time and make our lives easier!

Optimizing Video Localization with ML and AWS Batch

Thu, 01 Jun 2023 10:10:10 +0100

As you may know, I had the opportunity to speak publicly during AWS Community Day Warsaw. The talk was about a non-trivial challenge related to AWS services. Since there was no recording available and the slides alone are not sufficient, I decided to write a blog post to document this homegrown project. During the showcase, you will see various services and encounter different issues. If you have any questions, feel free to reach out to me on LinkedIn or via email.

Simplify the networking with VPC Lattice

Sat, 08 Apr 2023 10:10:10 +0100

I started writing this on April 7th, 2023, a few weeks after the release of VPC Lattice (although it's not yet available everywhere). I was curious about what it is and what it's supposed to do, so I asked ChatGPT.

As there isn't much information available yet, I'll rely on the official documentation for now.

According to the documentation, "Amazon VPC Lattice is a fully managed application networking service that you use to connect, secure, and monitor all of your services across multiple accounts and virtual private clouds (VPCs)."

Can you use ECS without DevOps

Thu, 16 Mar 2023 10:10:10 +0100

Use your imagination and assume that some team was encouraged to migrate from Azure AppService. It was a decision at a high level, so the small dev team needs to migrate into AWS. What's the issue you can ask? They have no experience with Amazon Web Services, also they don’t have a "DevOps" person. The app is a JAR file. AppService allowed them to put a file into the service and run it on production, without any issues. When they started looking for an alternative on the AWS side, the only solution they found was Elastic Beanstack, unfortunately, the workload fits better into the "docker platform". ECS from another hand doesn’t provide "drop-in" functionality. And that's the case. Let's check how easily we can build the bridge!

How to use Lambda as a glue?

Thu, 09 Feb 2023 23:10:14 +0100

Let's keep this article short. The topic is rather popular, but not very well documented. It's based on quite a popular issue, which is about untagged EC2. Sometimes developers launch virtual machines, without tags. Why it's so important? Because without tags, you have no idea about the machine's purpose. You have no owner, now, project, no cost center, etc. I know that some of these things can be checked with CloudTrail, however, it's still about keeping the environment clean. After kindly asking, reminders, etc, I decided to go with a slightly different kind of solution. The brutal one.

Salt on Graviton

Fri, 27 Jan 2023 18:10:14 +0100

It will be nice to solve another real-world problem, isn’t it? For example machines in private subnets, behind the NAT, or on rack shelves in an office. All of them need to be managed - at least from time to time.

Ansible is great, I appreciated the creators of this tool. It helps me a lot! In different cases, environment. I remember when I was a bit younger, a very popular interview question was - what is the difference between Ansible and Chef/Puppet ?. If we skip the part, that Chef/Puppet isn't very popular in Poland, the main and always correct answer was that Ansible is agentless.

Sailing with AWS Lightsail

Wed, 28 Dec 2022 18:10:14 +0100

I have a daughter! What a piece of news, isn't it? I can also add again the same line:

Newsletter is very time-consuming, and being a consultant is time-consuming. Everything is time-consuming.

However, I had some spare time to play a bit with a small client's project. For example, not everyone needs cutting-edge technology, Kubernetes, and functional programming.
Sometimes we just need a small VM with IPv4, for PoC, or small old-style application, or even workshops about Linux administration. Here I want to introduce a bit unpopular AWS solution - Lightsail. It's a neat service. Fast, very easy to use, and cheap. The smallest bundle is 3.5$/mo. However, it has some limitations. For example, it is unpopular - there is no ansible dynamic inventory plugin for it - what a shame. Let's fix it then!

CDK8S workflow example

Sun, 31 Jul 2022 18:10:14 +0100

After a long break(again!) - I'm back. Older, more tired, and handsome as always. Newsletter is very time-consuming, and being a consultant is time-consuming. Everything is time-consuming. That's why I decided to write this post with a bit different approach. Let's talk about processes. The tech part is still most important, unfortunately, sometimes it's not the key. So what is CDK?(generated with rytr) CDKs are a set of tools that enable developers to make use of the cloud environment. They provide a set of tools and resources that allow developers to deploy their applications in the cloud. CDKs are used for different purposes such as:

Cloud-init with DigitalOcean

Mon, 20 Sep 2021 12:10:02 +0000

Welcome

Another build something yourself article. The last one was focused on Kubernetes. Now I will try to build infrastructure for a bit different side-project. I always want to learn SaltStack. To be honest, I'm a huge fan of Ansible which is boring, but works. However, sometimes I have a problem with keeping my developers account synced. Also adding multiple users and track their settings is hard without states. So I decided to get into the new toolbox. Additionally cloud-init with DigitalOcean API sounds like fun.

EKS on speed

Sun, 01 Aug 2021 12:10:02 +0000

Welcome

Let's build some stuff. Today on AWS(EKS). Today with popular solutions and almost without coding(in YAML). Today focus on speed and simplicity. Additionally no CI/CD.

Components

I will keep it simple.

Terraform
aws cli
docker
helm
curl
dig, kubectl, emacs

Building infrastructure

Setup

First steps. I need to build some infrastructure. As almost everyone use Terraform for building and managing resources I decided to use it too. Based on Terrafrom EKS module I've created a sample manifest. Also, I decided to add ECR and configure output in a specific way.

Gitlab - templates

Tue, 15 Jun 2021 12:10:02 +0000

Welcome

Working as a consultant is hard. You have so many tasks to do. The day is a bit too short, but the opportunities to learn are awesome. Today I have time to compile my notes about GitLab, mostly CI part. However, as a code repository for organizations, GitLab is my favorite solution. Fast, easy to use, permission matrix, and deployment keys management. All this stuff is awesome. It's not a marketing post, but could be :)

Jenkins and submodules

Fri, 02 Apr 2021 18:10:14 +0100

Welcome

That will be a short post, rather full of my pain and frustration. Fortunately with happy-end and topic for a small article.

Problem

GitHub has some problems with service accounts for CI/CD usage. At least in Free Plan. You can't share deployment keys like for example in GitLab. I can understand that in the context of security, but If you have 4,5, or 15 repositories, you need to manage the same numbers of ssh key pairs. That is annoying, but I used to it. The problem comes when you need use sumbodules in CICD pipelines with Jenkins. Let's say Jenkins also has probem with submodules. In general if you're using multibranch situation is documented:

Ansible with jump host

Tue, 23 Mar 2021 12:10:14 +0100

Welcome

Long time no sea. It's not a typo last time when I saw the see was in September in Greece. Almost the same thing I can say about Ansible. The last time when I used this tool for resolving real problems was more-less 2years ago. To be honest, during this period Ansible becomes (in my mind at least) just another boring and old-fashioned tool. Who is using Ansible if we have containers, Kubernetes Engines and Serverless? Only boring people. However, do you know who does not use Ansible? People without personal life or interesting problem to solve. I'm boring...

The Nginx and how to configure it

Wed, 24 Feb 2021 18:10:14 +0100

Welcome

That will be a short post. I need it, for my usage. All about Nginx and some application architecture. Why? During my 6 years of professional life, I haven't met any Nginxa's master. All my tech friends know some basics(as me) or have one best config which always works. Unfortunately, Nginx is hard. It's just a tool, just a web server, but it's complex, useful, and powerful. Let's start.

edb-deployer for normal people

Mon, 15 Feb 2021 18:10:14 +0100

Welcome

Some time ago I saw an interesting tool called edb-deployer. If You have no idea what EDB stands for it's Enterprise version of Postgresql. I'm not a sell person, so for me, it's just another company which making money around OSS - and that is good. However, I would like to tal... write about this small CLI tool. It could be very helpful for the migration to cloud PoC toolbox. Sounds good? Wait for the rest of the article.

2021's Plans, Jenkins plugin and Emacs

Sat, 09 Jan 2021 18:10:14 +0100

Welcome

How are you? I hope 2021 starts at least such good as for me. Even without the New Year Party. Maybe you noticed that I deleted the cookbook section, and it's all about splitting topics. It's a tech blog, the rest of my hobbies need separated space. I hope you like this idea. After a few words let's begin.

2021 Plans

10 months of writing, 12 posts I can say that I really like this. Maybe it's time-consuming and not such great as OpenSource contributions, but it's on my own rules. I can write when I have time, I can write about everything still. No cookies, no Google Analyst, no opinion about my work here - from my perspective it's a very comfortable situation.

NodeJS app on LKE with Pulumi

Sun, 06 Dec 2020 18:10:14 +0100

Welcome

I had an interesting idea, write a small app with something. Deploy this app on K8S on Linode (LKE), with the usage of Pulumi. I started with the Golang app as well as with pulumi-go, but I realized that I can turn it into a bit more fresh experience. I've never before use Node and TypeScript. Also building images for another toolset is always a challenge, especially if you in normal life use npm build, and push all artifacts on Nginx. The post is one of the longest on this blog, I hope it will be interesting for you at least it was for me.

Should I use Quarkus

Mon, 23 Nov 2020 18:10:14 +0100

Welcome

As mentioned in a previous post, I'm working more with the RedHat stack. Most of these tools are very interesting. Like Quarkus - another Java framework. Not boring Java framework, Quarkus is fast, working on GralVM instead of regular JVM. But the biggest advantage is native builds. We can create an app, pack it into binary, and run it inside a container. That container could be used with serverless without cold-start issues. How cool is that? But...Today I will be focused on regular OpenShift deployment and some coding.

Move to my own domain with OVH and Netlify

Sun, 15 Nov 2020 18:10:14 +0100

Welcome

Long time no see. Due to the last 2 months, I had some changes in my personal life. I've become a Solution Architect in a nice polish company. If you or your friends need some RedHat implementation here is the link. What will change here? I hope nothing. Still a lot of CI/CD topics, more Kubernetes(with OpenShift), maybe some serverless with Knative and quarkus. Ahh and some new tools. Linode as a cloud service and Pulumi as Terafrom's replacement. Unfortunately, today I will be focusing on setting up my own domain on different hosting without Github Action.

Go app on Kubernetes from scrach

Thu, 20 Aug 2020 18:10:14 +0100

Welcome

I like GitHub Actions, I like Kubernetes and I want to learn more about Helm. So maybe I should join these tools and make a smooth pipeline? Why not? Also, I switched to Fedora, and that's a great moment to checkout Podman in action. No time to wait, let's go.

Tools used in this episode

GitHub Action
Podman
Kubernetes
Terraform
Helm
GCP
A bit of Golang :)

Build the app

The first step is building a small app. I decided to use Golang because it's an awesome language for microservices and testing is clear.

Why I need VIM?

Fri, 10 Apr 2020 18:10:14 +0100

+++ draft = false date = 2020-04-10T20:30:02Z title = "Why I need VIM?" description = "Short story about legendary tool" topics = ["Tools"] +++

Welcome

During quarantine, I expected to have more time. Unfortunately I fall in love with making Neapolitan Style pizza, sourdough based bread, and homemade tortillas. However, also I decided to master VIM. But why? I would like to explain it in a few words.

What's is VIM

Vim is a highly configurable text editor built to enable efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems. Vim is often called a "programmer's editor," and so useful for programming that many consider it an entire IDE. It's not just for programmers, though. Vim is perfect for all kinds of text editing, from composing an email to editing configuration files. Despite what the above comic suggests, Vim can be configured to work in a very simple (Notepad-like) way, called evim or Easy Vim.

Build your onw GitHub Action

Thu, 26 Mar 2020 18:10:14 +0100

Welcome

Sometimes age I started using GitHub Actions. It's fast, simple, easy to configure. There isn't a lot of fancy configuration options like for example in Jenkins, but if someone has neat, container-based pipelines, Actions are worth considering CI/CD system. But what this Actions really mean? Actions are mostly community written code that is responsible for activities like, pushing image, sending the notification, checking source code. There are two options for developers: Bash and JavaScript. Unfortunately, I have two operations which haven't ready Action. So I decided to write my Action and support the community. At least I hope it will be helpful for someone.

Build grammarbot client in Go

Tue, 10 Mar 2020 18:10:14 +0100

Welcome

While working with grammarbot, I decided to create my own command-line tool/client for working with API. As a language, I have chosen Golang. After that, I have added GitHub Action and gsutil. Also, I have configured Telegrams bot for notification purpose. Sounds like fun? For me definitely. So stop writing, and show me your code.

Continuous integration/testing for static blog

Tue, 10 Mar 2020 18:10:14 +0100

Welcome

In a previous post, I created a static blog with a basic CD. Now I need to add some CI.
Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.
Why it's mandatory? Because of my grammar errors, formatting errors, and general errors. Nobody wants to have typos, broken markdown content on the official blog page. At least I want to avoid it :) So I decided to use markdownlint, project as my Markdown linter. Also, I need to integrate my content with some grammar checker.

Continuous delivery for static blog

Sun, 01 Mar 2020 18:10:14 +0100

Welcome

I'm still writing about my blog, just ordinary auto-promotion. However, I'll try to make this particular article useful even in a different context than blogs. The next few lines will be dedicated to continuous delivery (without continuous integration/testing).
As I showed in previous issues manual work is easy and in some case fast. Unfortunately, it's also boring, prone to errors and time-consuming. How to achieve good results without self-hosted CI servers, expensive solution or custom scripts on VPS? At this moment in time(29022020) I know only two nice and easy tools that meet my assumptions. Which one will be better? Let's check it.

Build static blog on GitHub Pages #2

Wed, 26 Feb 2020 18:10:14 +0100

Welcome

In the previous episode, I have created a short blog post about short blog post. That was quite interesting for me, in meantime, I configure my VSC for English support, add some small fixes in the Markdown file then I realized that the manual reload of configuration is a huge mistake in the context of productive. What is the first tool when we start thinking about automation? In Linux environment of course. For me, it's Bash. Let's begin then.

Build static blog on GitHub Pages #1

Mon, 24 Feb 2020 18:10:14 +0100

Welcome

Everyone sometimes thinks about personal website. Nothing fancy, just static content with clever topics... sounds easy, isn't it? The only problem is how to host this page and how to do it fast (and as cheap as is possible). So where comes GitHub Page. The main reason why I choose this solution is the price and domain. 3sky.github.io will look cool, almost professional. The question is why I will do it harder than it's recommended? The answer is simple because I can. Technology is all about curiosity and people who like to do stuff. After a short introduction let's start.
