koeveton How I use Claude Code: Separation of planning and execution

Has anyone found a efficient way to avoid repeating the initial codebase assessment when working with large projects?

There are several projects on GitHub that attempt to tackle context and memory limitations, but I haven’t found one that consistently works well in practice.

My current workaround is to maintain a set of Markdown files, each covering a specific subsystem or area of the application. Depending on the task, I provide only the relevant documents to Claude Code to limit the context scope. It works reasonably well, but it still feels like a manual and fragile solution. I’m interested in more robust strategies for persistent project context or structured codebase understanding.

koeveton Last Week on My Mac: Losing confidence

I moved back to Arch Linux after my 11 months old MBP died and took over a month to get it fixed. Not really looking at going back to macOS. There are no aspect of the Apple OS that I miss and Linux desktop just works nowadays.

koeveton Leaving Gmail for Mailbox.org

It’s funny, the very first thing you see when visiting mailbox.org is their heavy push of the "German quality" mantra, like it's 1999.

After living seven years in Germany, I can confidently say that when it comes to anything digital, “quality” is the last word I would use.

I certainly wouldn’t trust this company with my data.

Saudi Arabia has killed and dismembered a journalist in their own embassy in Istambul, Jamal Khashoggi.

But wasn't Iran already docile to America? Sure, it wasn't a crystal clear ally like Saudi or the Gulf states, but behind the anti-Zionist propaganda and "evil US" blabbering, there were decades of backchannel negotiations, regional pragmatism, and even moments of cooperation — especially when mutual interests aligned, like in post-Taliban Afghanistan or the fight against ISIS.

koeveton Ask HN: Does Duolingo Work?

It didn't work for me. I spent ~2 years trying to learn German and all I managed to retain are a bunch of nouns, verbs and adjectives. I am still unable to speak properly, let alone read a newspaper article. I suspect that the Duolingo "teaching style" does not work for me. It also depends on the objectives, since I was more interested in some kind of fluency as opposed to being able to read or write in German.

koeveton Ask HN: What are you working on? (October 2024)

I am the maintainer of beanborg (https://github.com/luciano-fiandesio/beanborg), a set of scripts for automated categorization of financial transactions on top of beancount. Using plaintext accounting in the last 5 years has dramatically improved my family's financial health. Unfortunately, plaintext accounting is not for everyone.

I noticed that there is a big gap in this space, especially for European users. There are several personal finance applications, but they seem to integrate mostly with US banks and, in general, they seem to be very dollar-centric.

So, I'm working on a simple app to manage personal finance, based on the concept of double-entry accounting with features like budgeting, projections and data analysis. There are a lot of privacy-related considerations, so for the time being I will eat my own dogfood and offer it to close friends. Let's see how it goes!

koeveton Ask HN: How Do You Budget?

I have been using plain text accounting for almost a decade with my wife. Specifically, I use beancount (https://beancount.github.io/docs/) and a custom set of scripts that I have developed to categorize expenses and other features (https://github.com/luciano-fiandesio/beanborg/)

I reckon is not for everyone, since a lot of stuff takes place in the terminal, but it has been working very well for us.

koeveton Show HN: Light implementation of Event Sourcing using PostgreSQL as event store

I noticed that you use the @Transactional annotation on class definition. This will create a write transaction for every public method of the annotated class, including read only methods. You should consider using readOnly=true for read methods.

Additionally, I would consider using two data sources, one for write queries and a read only ds for the Q part of CQRS.

This is from the GitHub page of the project:

The configuration holds realm data and users.

koeveton Ask HN: Has anyone gone back to boring technology (ex: Java/Spring)?

I struggle to understand what do you mean with "boring" technology. For me, what could be boring is a project or a "vertical". I have of course preferences around which language or framework to use, but I wouldn't label a techology boring: rather unproductive or complicated or not suited for the task.
