About
I'm ensuring every feature we build at Better Stack works and feels incredible. I wireframe features in the morning, talk to customers during the day, and code in the evening.
I've worked with infrastructure, monitoring, and deployment tooling at Showmax.
I used to work on spam and phishing detection at Seznam.cz.
I have a Master's in System programming from FIT CTU in Prague. As my Master's thesis, I have designed and developed a useful tool: https://github.com/curusarn/resh (hundreds of users)
I have completed a Bachelor's degree in Software Engineering at FIT CTU in Prague.
Things I have worked with:
Go, Kubernetes, Prometheus, Grafana, Python, C/C++, Bash, Git, Linux, Jsonnet, Tanka, Make, Ruby on Rails, GitlabCI, GitHub Actions, Docker, Debian packaging, Homebrew, Ansible, Kibana, Nginx, OpenStack, (OpenStack) Swift, Aerospike, Hadoop, Spark, Scikit, SQL, Java, JavaScript, HTML, CSS, Lua, Haskell, ...

What a treat! Note: I'm only sponsored for this post insofar as my daughter is excited to get a new t-shirt and a sticker.

Šimon Let shared thisSo cheap you'll think this is an April fools jokeŠimon Let shared thisToday, we're making Error Tracking by Better Stack generally available. Sentry-compatible. AI-native. At 1/6th the price. Here's why we built it, and how to get the most out of it. What's wrong with error tracking today? Most teams use Sentry. It's solid! But at scale, the bills get brutal. Just 100M exceptions with 90 day lookback? ~$30,000 on Sentry. We charge ~$5,000 for the exact same thing. The math isn't subtle. And so most teams still end up sampling. Which means missing the exact exception that caused the outage. The bigger problem: errors are orphaned data. Your exception lands in Sentry. Your logs are in Datadog. Your traces are somewhere else. Root cause analysis becomes a multi-tab archaeology project at 3 am. We built error tracking natively inside Better Stack: the same platform where your logs, traces, metrics, uptime checks, and on-call schedules already live. Errors are just another signal. They belong together. The part that changes how your team works: Our AI SRE doesn't just surface errors. It fixes them. See a new exception? One click. The AI SRE analyzes the full context, from stack traces, environment variables, browser sessions, related logs and recent deploys, and opens a pull request. Not a ticket. Not a summary. A pull request with the fix. This is what happens when error tracking is fully integrated with the rest of your observability stack instead of bolted on separately. The AI has everything it needs to actually act. The migration is trivial: 1. Keep your existing Sentry SDK. Don't touch a single line of instrumentation code. 2. Point the DSN at Better Stack. 3. Done. Errors flow in. Your dashboards work. Your alerts work. 4. New exception appears. Click "Fix with AI SRE." Pull request lands in your repo. 5. Review, merge, close. That's the whole workflow. The AI angle is real, not a marketing badge. LLMs are genuinely good at fixing bugs if they have full context. The reason AI coding assistants sometimes frustrate engineers is incomplete information, not the model. We solve that by giving the AI SRE your entire telemetry stack as context. Stack traces, logs, traces, service maps, previous incidents and much more. All of it, in one place, at the moment it matters. Observability tools are only useful if you actually ingest all your data. At current prices of other tools, most teams can't afford to. Now you can, and your AI SRE can actually do something about it.

Šimon Let reacted on thisŠimon Let reacted on thisI’ve been using Better Stack for the past few days. The thing that stood out most was not a specific feature. It was the UX. Logs, metrics, traces, dashboards, everything is easy to find without needing to learn the product first. Observability tools are often powerful but exhausting to use. Better Stack feels like someone actually cared about reducing that friction.

Šimon Let liked thisŠimon Let liked thisSharing our internal "no-bullshit guide to Agentic Engineering" Link in comments --- Practical guide to shipping production-ready software in hours instead of months. # A practical mental model If you ever find yourself saying: “AI is not good enough yet to do [action]”, please automatically assume you’re wrong. It’s just practical to do so. It forces you to think “*how* do I make AI do this?” AI is ready today, except for real-time video calls. So the odds are you just don’t know how to configure it properly. Just because you installed Claude Code doesn’t mean you’re leveraging the full power of AI for software development. Always be learning: specifically, keep asking other engineers to show you their CLAUDE.md. [link in comments]

A třeba někoho inspirovat, aby začal tvořit vlastní věci. Snad se to povedlo! Nakonec se nám totiž za těch 6 měsíců nastřádala spousta krásných příběhů (a fuckupů), které stály za sdílení. A ty obavy? Rozhodně nekončíme. Naopak! Stejně mě fascinuje, že tohle všechno začalo jedním úplně absurdním nápadem před 7 lety. Oběhnout všechny stanice pražského metra. A udělat si k tomu malou appku. Who would’ve thought 🖤

👋Hey DBAs and SQL Server Developers! If you’re dealing with very large tables - tens or hundreds of millions (or more) of rows - and performance keeps biting you in production, this session is perfect for you. Miloš Radivojević dives into the real performance problems that only show up at scale, focusing on what actually breaks when tables get big. You’ll learn how to: ✅ Avoid catastrophic performance issues caused by missing or poorly timed indexes ✅ Write queries that still perform well when tables grow massive ✅ Understand why cardinality estimation and statistics go wrong on large tables ✅ Control statistics sampling, auto-update behaviour, and avoid surprise timeouts ✅ Treat very large tables differently - because “standard maintenance” no longer works If you want to stop guessing, prevent outages, and confidently tune SQL Server at scale, this session will give you practical guidance you can apply immediately. 🎟️ Enjoyed this and want the chance to attend in real time? Tickets for SQLBits 2026 (22-25 April 2026, ICC Wales) are available on our website, including our new virtual passes. #SQLBits #SQLServer #DBA #PerformanceTuning #QueryOptimization #LargeTables #DataPlatform

Updated Post: Scaling Redmine on Linux for 500+ Users https://buff.ly/1CIIq05 When Tools Have to Grow Up With You For a small team, project management is simple: a few boards, a shared folder, maybe even spreadsheets. But once you’re running with 500 people, those tools start to collapse. Projects sprawl, deadlines slip, and nobody knows where the truth lives. That’s when an organization has to ask:

Starting with version 2025.3, Codex is available directly in JetBrains AI Chat in IntelliJ IDEA, PyCharm, WebStorm, Rider, and other environments. The agent handles large-scale refactoring, migrations, feature development, and vulnerability analysis without leaving the IDE. Developers can switch between OpenAI models and manage compute resources depending on the task. The level of autonomy is configurable, and the team retains full control over the process. When used through JetBrains AI, Codex is available free of charge during a limited promotional period, until the allocated credits are exhausted. AI in software development is moving toward full-fledged agent-based scenarios. If you are considering implementing such tools in an enterprise environment, the Noventiq team is ready to discuss practical use cases and an appropriate adoption model.

Flox and Nix solve a lot of the problems that often containers are used to solve and in my opinion much more elegantly. But that doesn't mean they replace containers in every scenario. Checkout this talk (or this blog post: https://lnkd.in/ezfPiy2k) on how using them together is truly more than the sum of their parts!
