I'm Javier Cacheiro López (<a href="https://github.com/javicacheiro">javicacheiro</a>), Scientific Director of the <a href="https://dataspace.cesga.es">OneHealth DataSpace</a> at <a href="https://www.cesga.es">CESGA</a>, the Galicia Supercomputing Center.</p> <p>I've just rebuilt this site with <a href="https://astro.build">Astro</a> and the <a href="https://github.com/cworld1/astro-theme-pure">Pure theme</a>, and I plan to use it for two things:</p> <ol> <li>As a landing page for anyone who wants to know who I am and what I do.</li> <li>As a blog where I write about the technologies I work with every day.</li> </ol> <h2>What to expect here</h2> <ul> <li><strong>HPC</strong> — supercomputing in practice: schedulers, storage, performance tuning.</li> <li><strong>Quantum Computing</strong> — the road from experiments to useful quantum-HPC workflows.</li> <li><strong>AI</strong> — training and serving models on real infrastructure.</li> <li><strong>Big Data</strong> — data engineering at scale, from Hadoop's era to today's lakehouses.</li> <li><strong>Cloud</strong> — automation and platforms for scientific and industrial workloads.</li> <li><strong>Data Spaces</strong> — sovereign data sharing, the technology behind projects like the OneHealth DataSpace.</li> </ul> <p>Stay tuned — and if any of these topics interest you, you can follow the <a href="/rss.xml">RSS feed</a>.</p> <pre><code class="language-bash">$ shutdown -h "see you in the next post" </code></pre>
