Docker Sandbox’es just got a nice way to customize them. Personally, it feels like a missing piece I was looking for a while already

Somewhere out there, two conference organizers are deciding if I belong on their stage. Wild that this is something I get to be nervous about now.

Genuine question: why did we decide that the best place to receive security codes is on the same device where all our distractions live? The people who designed 2FA and the people who wrote deep work books clearly never had a meeting.

New job. New team. They use Kustomize instead of Helm. I’ve used both. But there’s a big difference between “used it” and “lived in it for 3 years.” I’m basically junior again and I hate it. Anyone else made this switch? Helm or Kustomize. Which side are you on?

At new work - they issues 14” MPB with M5. 14” feels so small. Ok, at the office, it’s usable with the extra monitor setup. But while traveling or working from home - it’s a bit too small for my personal preference. What’s your preference? 14” or 16”?

Next Friday will be my last day at the company. I have been here for the past 12 years. It is certainly an unusual experience, and I feel a mix of sadness and uncertainty about my future.

Docker Model Runner now supports the NVIDIA DGX Station GB300. The hardware is powerful but what makes it practical is the developer experience: pull, run, and iterate on larger models using the same Docker workflow you already know and trust. Learn more here: https://bit.ly/4dX6w7g

If you've ever had a production incident caused by an upstream image change, a mutable tag, or a dependency you didn't know existed in your Dockerfile — this is the post I wish I'd had. Docker build policies in 5 minutes, two copy-paste examples, zero excuses left.

Unpopular opinion: your Dockerfile review process is security theater. Humans miss things. AI assistants suggest things. Tags are mutable. latest is a lie. The only review that can't be skipped is one that runs before the build starts. Wrote about how to set that up with .rego policies in ~5 min.

Stop writing Dockerfiles like it’s 2015. You don’t need 47 lines of apt-get install, apt cache clean, and rm -rf just to build a base image. DHI lets you build Docker base images without a Dockerfile at all. Define what you want, skip the boilerplate, and stop pretending that cleanup is fun.

First day back and I'm already gearing up for the hardest conversation of the year. My CTO's tech stack choice is fundamentally broken, ChatGPT agrees with me, and now I have to somehow convince leadership they're wrong without becoming the person who got fired on day one. This is going to be fun.

Only one day left in 2025! Overall, it was a fantastic year. The only downside was that two long projects finally came to an end. One of them, which I'd been working on for ten years, was finally finished. What about yours?

Another issue with Ghostty, particularly on SSH connections, is that it doesn’t recognize the terminal type. While it’s easy to fix by adding a SetEnv command inside the .ssh/config file, it’s still an annoying problem that doesn’t work out of the box.

Everyone is excited about AI. Many of us are using AI workflows to optimize our daily tasks. However, would you trust AI to manage payroll, or an accountant to use AI to automate the transfer of employee salaries?

.NET, about a week ago: We wanted notifications on changes/deletions of specific entities. Simple. Override SaveChanges and fire based on ChangeTracker. Implemented. Works. Yesterday: Something wrong. Zero deletes. A few breakpoints later: Using a helper which doesn’t use EntityFramework. 🙈

Vibe coding without Vibe bill? It's possible. Qwen Code. Docker Model Runner. 0$ Want more details?

The loneliest founder journey? Solo SaaS builder. The hardest founder journey? Solo SaaS builder WITH a family. If you're doing both, you're built different. Let's connect 👇

Just opened a 3-year-old iOS project. Hit build. It compiled. First try. No errors. No warnings. Meanwhile, Android projects after 6 months: • AGP version incompatible • SDK target outdated • Gradle sync failed • "Google is your only hope" error messages.

Building a SaaS solo while juggling family life (partner + kids)? Drop a comment below 👇 You're the real heroes and I want to follow your journey. The hustle hits different when you're debugging at midnight and packing school lunches at 6am.

Big month is here: • In a few weeks I'm going to speak about #Docker Model Runner at #helmes • In the end of month - going to Turkey to meet other Docker Captains & Employees.

What is your AI assistant persona? Mine, is always making weird jokes at the end. 😅

This year I'm not buying the latest iPhone 17 Pro Max. But I'm just one click away from getting DJI Mini 5 🤩

Another day - another story, or should I call it - the more access you get - the more issues you see? Got a bug raised around GoogleAnalytics & Google Ads conversion tracking. That numbers looked weird. To solve this, I also got access go GA console, and the fun started...

Yesterday, I've asked how we can access application logs of live/prod deployments. I got answer, that I need to contact one person, and he will give me the zip archive with the logs of application on demand. No central logging are in place. With my DevOPS background - I felt like in stone age.

Docker just open-sourced a new CLI tool for managing AI agents called cagent: 🔧 Agents can use external tools and APIs via the MCP protocol 💭 Built-in "think", "todo" and "memory" tools 🌐 Support for OpenAI, Anthropic, Gemini and Docker Model Runner. Give it a try: github.com/docker/cagent

Got yet another offer to host someone else app in my google play console. This is against developer agreement first, so I wonder what they are even trying to scam?

Have you ever had to create a lecture or tutorial for specific tasks, such as getting started with a particular SDK, introducing a framework, or testing? What tools have you found most helpful for this purpose? How have you ensured that students have all the necessary tools ready?

So, I've started building my own uptime monitoring solution, after multiple years of using uptimerobot.  I still use Pulsetic now, but I hope to build something better than it myself. Why? Well, I want to build something myself, and I'm already tired of everyone doing yet another habit/todo app.

Have you replublished all your Android apps with 16kb page size requirement already?

Never build an audience on a single social network only. I did that mistake, and now - I need to start from scratch. (Still hoping I can regain access to that account)

Got my account suspended on Threads. They do offer to download all account information - but that only includes followers, and followees, but it doesn't include any of my posts history - so it's basically useless.

Ok, I’ve just got banned on Threads with no reason. Literally just commented on a post about hosting providers, and tagged my choice. Lol.

Day 1: SaaS idea 🌟 Day 2: Buy domain & code starts Day 5: Life gets in the way... Day 345: "Do I renew the domain?" Tell me you’ve been there too.

Yesterday I've worked on clearing up the idea and designing the architecture of my first SaaS. Had an interesting conversation with a few AI models, created a repo, skeleton for website & API, dockerfiles, compose.yml Stack: Go + Templ + TailwindCSS.

Everyone seems to be building yet another habit tracker, and that field - overcrowded. My next project - uptime monitoring solution. A very niche product, but at least competition is smaller.

Looking for different uptime-monitoring solution... Got tired of UptimeRobot which periodically gives false alerts and burn notification credits. Any recommendations?

Today marks my last day in Viavi Solutions. It's hard to say goodbye after spending over a decade here. It was a pleasure working with you!

@docker.com announced Docker Offload yesterday during #WeAreDevelopers. I've already tried it, and personally think it's a great feature, especially if you working with AI, agents and some extra juice for your pc. More details on my post. #Docker #DockerOffload #AI

Whoops! Helm got broken. Helm 3.18.0 seems to introduce a breaking change which affects a lot of uptream helm charts. Stay at the 3.17.x 🙈

My relationship status with Shopify is complicated. One day I love it. Next one I want a divorce 💔

AI + Docker = ?

#Docker just released a way to run LLM locally on your mac without any additional software. More details in my blog.

Today at work: • Meetings • ArgoCD & gitops related activities • More meetings After work: • Migrating a few domains to new server (Nginx/php/MySQL) Before work: • Running LLM locally on my macbook (openai compatible) • Figuring out how to set it up with zed.dev

Runs a docker registry with TLS on localhost. Spends half a day forcing go-containerregistry library to use HTTPS and not HTTP for doing a push to localhost. 🙈😂

• Signs a new contract with a new customer • Gets access to existing codebase & deployments • Production Stripe keys in plain-text on the first repo I clone… 🙈😭😭😭😭

#Docker just announced docker #bake. On my blog post, you can find my first impressions and a few examples. #cicd #devops #containers #automation

Use Strimzi, they said… Use ArgoCD, they said… It’s going to be fun…. Yes. Indeed. Very fun. Strimzi operator creates the resources based on it’s CRD and ArgoCD deletes them. In a loop. Nothing works. Fun. Indeed. 😂🙈👌

Did you know you can run GitHub workflows locally using ‘act’? This CLI tool simulates your GitHub Actions environment right on your machine. It even works with Gitea pipelines! Local testing saves time and reduces unnecessary commits. Have you tried ‘act’? #DevOps #GitHub
