I want a system where messy thoughts go in, meaningful writing comes out — powered by AI that knows my voice and my purpose.https://wijnandbaretta.com/posts/why-im-building-with-ai-even-though-its-hard/Tue, 04 Nov 2025 00:00:00 +0000https://wijnandbaretta.com/posts/why-im-building-with-ai-even-though-its-hard/This isn’t about chasing a trend. It’s about not wanting to sit on the sidelines of the biggest shift in how humans work — even if learning to ride the wave means wiping out a few times.https://wijnandbaretta.com/posts/2025/03/glossary-of-llm-related-terms/Tue, 25 Mar 2025 15:09:39 +0100https://wijnandbaretta.com/posts/2025/03/glossary-of-llm-related-terms/<h1 id="-glossary">📚 Glossary</h1> <hr> <h2 id="-general-terms">🧠 General Terms</h2> <ul> <li> <p><strong>LLM (Large Language Model)</strong><br> A machine learning model trained on vast amounts of text data to understand and generate human-like language.

First, I ask ChatGPT 4 the follwing (quite elaborate) question:</p> <p><em>I know there are a million different fitness apps out there and hardly any on eof them actually &ldquo;works&rdquo; in the sense that it automagically gets people to work out.</em></p> <p><em>So before even considering building something, we need to analyze what an app&rsquo;s actual job is.</em></p>https://wijnandbaretta.com/posts/2025/03/using-ai-to-lead-a-happier-life/Mon, 24 Mar 2025 17:16:23 +0100https://wijnandbaretta.com/posts/2025/03/using-ai-to-lead-a-happier-life/<p><em>(And Not Lose My Mind in the Process)</em></p> <hr> <p>Let’s be honest. I’m not a monk meditating on a mountaintop. I’m not waking up at 5 a.m. for cold plunges and journaling. (Okay, I tried journaling once. Lost the notebook. Still looking for it.)</p> <p>What I <em>am</em> doing is trying to figure out something that’s been bugging me for a while:<br> 👉 <strong>How can I use AI to lead a happier life?</strong><br> Because, if you’re anything like me, life can feel like a never-ending ping-pong game where you’re both players, the ball, and somehow also the table.</p>https://wijnandbaretta.com/posts/show-books-collection-dynamic-with-javascript/Fri, 15 Nov 2024 09:05:43 +0200https://wijnandbaretta.com/posts/show-books-collection-dynamic-with-javascript/<p>On this website, I have a bookcollection. All the books I have on my Kindle, are displayed here. Showing the cover, a summary, key takeaways. In addition to that, I have added <em>tags</em> to each book, so I can filter the collection and only show the books with that specific <em>tag</em>.</p> <p>However, these pages with books per tag are a lot more boring than the general collection of books, where we are showing all the covers. So, showing the books with covers on the filtered pages would be nice. But, when thinking about that, it seems that having the content for the book-information in a csv or a JSON is a lot more practical: easier to maintain and update, faster to display and filter.</p>https://wijnandbaretta.com/posts/wielerspel-2021/Mon, 15 Nov 2021 21:14:48 +0100https://wijnandbaretta.com/posts/wielerspel-2021/<p>Seizoen 2021. Een virtuele veiling. Op afstand, van achter de computer, een ploeg bij elkaar rapen. Ach, niet zo&rsquo;n probleem, we zien elkaar allemaal later in het jaar wel weer. Misschien kunnen we wel met z&rsquo;n allen naar een koers, dat hebben we in al die jaren eigenlijk nog nooit gedaan. Zometeen wordt het zomer, dan kunnen we met elkaar afspreken, elkaar weer zien.</p> <p>Het loopt anders. Waar we al jaren morbide grappen over maken, gebeurt plotseling echt. We zijn niet meer met vijftien. We missen iemand. Hij staat dan wel fier bovenaan, maar we horen niet dat hij met z&rsquo;n gezondheid tobt.</p>https://wijnandbaretta.com/posts/command-line-shortcuts/Fri, 08 Oct 2021 08:12:29 +0200https://wijnandbaretta.com/posts/command-line-shortcuts/<p>Why not create shortcuts/shell scripts to open a project, similar to the script to create a new post?</p> <p>I could make it so that if I want to open a project, I cd into the directory belonging to the project, activate the environment and start up a server. I could even make it so that all projects start a server on their own port, so multiple projects could have a simultaneously running server.</p>https://wijnandbaretta.com/posts/scotch-whisky-distilleries/Wed, 22 Sep 2021 08:29:14 +0200https://wijnandbaretta.com/posts/scotch-whisky-distilleries/<p><a href="https://wijnandbaretta.com/posts/scotch-whisky-sassenheim">Other post</a></p> <p>So, data is (going to be) very important for Scotch Whisky Investments.

Both are important.

Read below for the idea of V-bucks. Revisiting this old post, I ask ChatGPT to help: <a href="https://chatgpt.com/share/67351ff2-8f14-800a-a499-0120b9518c78">https://chatgpt.com/share/67351ff2-8f14-800a-a499-0120b9518c78</a></p> <p>This is still an interesting and nice idea to build a MVP for.</p> <p>The V-Bucks project (or better yet, in this phase: idea) has originated at home, because my sons would like to earn money (to spend on V-bucks, the virtual currency used in Fortnite) and I would like them to do some chores in and around the house.</p>https://wijnandbaretta.com/posts/command-line-moving-files/Thu, 16 Sep 2021 08:36:24 +0200https://wijnandbaretta.com/posts/command-line-moving-files/<p>Instead of litterring my site with small posts describing how to perform as certain task, I will devise a plan to really learning to master the command line. I have <a href="../books/the-linux-command-line.md">a book about the command line</a>, which can help to create an overview of what&rsquo;s there to learn about the command line.</p> <p>Broader than just the command line, what do I want to learn? On the positive site, I have learned a lot and I keep learning new stuff. On the other hand, it is sometimes not very focused and, just like myself, all over the place. I don&rsquo;t know if that is a negative thing per se, or something I should change, but it would help me (I think) to make it easier to pick up where I have left sometimes.</p>https://wijnandbaretta.com/posts/my-static-hugo-site-todo-list/Tue, 07 Sep 2021 09:24:42 +0200https://wijnandbaretta.com/posts/my-static-hugo-site-todo-list/<p>OK, I have my HUgo site running locally and it is working fine. The script I have created to <a href="https://wijnandbaretta.com/posts/create-post-via-shell-script/">create new posts from the command line</a> is also very nice. No need to cd into any directory, just type <code>bash $ new-post.sh </code>, give a name and some tags and my new post is created and my editor is opened with that post, with the frontmatter in place.</p> <p>The site is looking good, I&rsquo;m happy with it, there are however some things I&rsquo;d like to do to improve it further.</p>https://wijnandbaretta.com/posts/i-m-so-easily-distracted/Tue, 07 Sep 2021 09:07:47 +0200https://wijnandbaretta.com/posts/i-m-so-easily-distracted/<p>Yeah, no need to complain about it. It is the same as falling down; just make sure to get up again. Or in case of distraction: make sure you get back to the thing you were doing (or aiming to do).</p> <p>I have found that there are ways to make it easier to get back to the thing(s) I want or need to do. Creating a list of things I want to do really helps. It is however, very important to curate that list on a daily basis. If I work with a list that contains more items than I can handle, it really doesn&rsquo;t help me.</p>https://wijnandbaretta.com/posts/hugo-better-suited-static-site-generator/Wed, 01 Sep 2021 09:21:24 +0000https://wijnandbaretta.com/posts/hugo-better-suited-static-site-generator/<p>There are several static site generators that I have tried, and <a href="https://gohugo.io/">Hugo</a> is now up for review.</p> <p>It claimms to be the fastest, with pagebuilds of 1 ms per page. That is certainly impressive, but there are other aspects of Hugo that appeal to me.</p> <p>I have looked at <a href="%5BPelican%5D:">Jekyll</a> and [Pelican]. I like Jekyll because it is tightly integrated with Github pages, making it easy to launch a site. What I don&rsquo;t like about Jekyl is that it is written in Ruby, mainly because I don&rsquo;t know Ruby well enough.</p>https://wijnandbaretta.com/posts/create-post-via-shell-script/Tue, 31 Aug 2021 00:00:00 +0000https://wijnandbaretta.com/posts/create-post-via-shell-script/<p>I want to write posts via the command line and I want it to be as effortless as possible. Every time I want to start writing, I end up in a loop:</p> <ul> <li>let&rsquo;s create a site to publish my writing</li> <li>what are the possibilities?</li> <li>Django or static site?</li> <li>which static site generators are there?</li> <li>This one&rsquo;s nice!</li> <li>it&rsquo;s perfect for what I want</li> <li>can I change the theme/templates?</li> </ul> <p>After a while, I have yet another nice static site. Sometimes all the way down to a published site, sometimes stuck somewhere half-way. But all of the time, the writing of content stops, doesn&rsquo;t get started, never happens. No matter what the reason for this is, I need to get out of this loop.</p>https://wijnandbaretta.com/posts/creating-a-new-git-repository-on-github-and-synching-to-it/Tue, 31 Aug 2021 00:00:00 +0000https://wijnandbaretta.com/posts/creating-a-new-git-repository-on-github-and-synching-to-it/<p>I want to create a new Git repo and write down the commands to add new content or create a script which does that for me.</p> <p>First, I go to the root directory of my (local) project and initiate a new Git repository:</p> <div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span>$ git init </span></span></code></pre></div><p>We now have an empty git repository.

I can now create new posts from the command line by simply calling the bash script I have created.
