Why I Shut Down a Few Blogs — And What Comes Next

by Teodor Costăchioiu April 3, 2026
written by Teodor Costăchioiu

If you landed here looking for an older article of mine, you might not find it anymore. That’s not a bug — it’s a decision.

After nearly three decades working in IT and remote sensing, I had accumulated a rather fragmented online presence: personal blogs, technical articles scattered across multiple platforms, experimental tutorials, posts that made sense when I wrote them but no longer reflect where I’m headed professionally.

I decided it’s time for a thorough clean-up.

What changes

I’m rethinking my online presence from the ground up. In practical terms, this means a few things:

I’ve consolidated everything that matters into a single place — this website. Secondary blogs have been shut down or are being shut down. Older articles — the ones that no longer brought meaningful traffic and no longer represented my current level of expertise — have been retired. Not out of nostalgia or haste, but because a library of outdated content does more harm than good, both for the reader and for the author.

Why now?

The reason is straightforward: I want what I publish to accurately reflect what I do. I mostly work in satellite image analysis, artificial intelligence for Earth observation, and software development for remote sensing. These are the areas where I have real experience, active projects, and relevant things to say.

There’s also a practical side to this. Maintaining multiple blogs in parallel was eating into the time I’d rather spend on actual work — research, code, and new articles. On top of that, there were the costs: theme licenses, hosting plans, and paid plugins. Consolidating lets me drop some of those expenses and redirect resources where they matter.

Everything you’ll find on this site going forward will be directly tied to my professional and research work — solid tutorials, case studies, tools, and insights from projects I’m actually involved in.

Nothing of value is lost

If an older article was useful to you and you can no longer find it, I apologize for the inconvenience. Genuinely valuable content has either been updated and folded into this site or will be rewritten in better form. The rest served its purpose at the time.

The old articles haven’t vanished entirely — I will keep them in an archive. If you’re interested in a specific piece, get in touch, and I can either put it back online or send it to you directly.

If you have questions or you are looking for something specific, don’t hesitate to reach out.
