This is an area where the boundaries of theory and practical application intersect, offering both incredible promise and immense challenges. If you’re tuning in to this podcast for the first time, welcome aboard. For regular readers and listeners, you...

Quantum computing has long been hailed as a transformative technology with the potential to revolutionize fields such as cryptography, optimization, material science, and beyond [ 1 ]. However, quantum computing faces a fundamental challenge: the fragility of quantum states. Quantum bits, or qubits, are extraordinarily sensitive to errors caused by environmental noise, decoherence, and operational...

We are going to spend some time digging into quantum computing over the next few weeks. Things are starting to move forward in that space which is exciting [ 1 ]. Let’s not waste a second and just go ahead and jump right into the deep end of this magical quantum puzzle. Here we go! Nondeterministic gates present a fascinating challenge within the evolving landscape of quantum computing. At their c...

Transfer learning has proven to be an invaluable tool in machine learning, enabling us to take advantage of pre-trained models to boost performance on new tasks, even with limited data. Instead of training a model from scratch, we can repurpose one trained on a large, diverse dataset to extract features—essential characteristics of the data—that are often applicable across various problems. For in...

As machine learning evolves, traditional approaches to feature engineering are being transformed by the power of graph data structures. Graphs—representing entities as nodes and relationships as edges—provide a rich framework to model complex, non-linear connections that go beyond what’s possible with tabular data. It’s an area of focus I keep going back to better represent knowledge. By embracing...

Thank you for tuning in to this audio only podcast presentation. This is week 170 of The Lindahl Letter publication. A new edition arrives hopefully every Friday. This week the topic under consideration for The Lindahl Letter is, “Are 8K Blu-ray a thing?” The short answer is no—there’s currently no official 8K Blu-ray format on the market. The highest-resolution Blu-ray available right now is 4K U...

Thank you for tuning in to this audio only podcast presentation.  Here we are, at week 169 of The Lindahl Letter, reflecting on a different kind of science—one rooted in a boldness that prioritized discovery over deadlines, adventure over immediate outcomes. This week’s topic, “Pure science from the last millennium,” brings us to a fundamental question: What do we want scientific investment to be...

We all thought you would be able to easily ask the house to turn on all the lights or command your television by voice to do things by walking into the room. Some of us thought the entire wall would be a television screen by now and that has not happened either. However, some of the new 100 inch TVs on the market are really large. Enabling automated actions is what is happening within the latest d...

This post is all Dr. Flint Dibble’s fault. That fault is wholesale based on all the #realarchaeology posts that have been flying around the internet [ 1 ]. If you missed all that online content about archaeology, then consider diving into all that informationally rich real archeology content. This week Flint got me thinking about how artificial intelligence and machine learning fit within the broa...

Thank you for tuning in to this audio only podcast presentation. This is week 166 of The Lindahl Letter publication. A new edition arrives every Friday.

For those of you listening to the audio version this week you may have noticed that we moved from the natural vocal capture to the narration vocal capture. I’m still recording the podcast audio for this adventure using a Blue Microphones Yeti X and my MacBook Air with the included GarageBand software. To further enhance your listening experience I’m still working to dial in the best possible recor...

Over the last week I started digging into quantum computer programming to see what is currently going on and what people are doing in that space [ 1 ][ 2 ]. General availability of actual quantum computing systems is the major barrier to using one to write some code [ 3 ]. You can buy time on a quantum computer or you can use a simulator. The simulators are sort of weird in general as the computin...

We are facing a new reality where the tipping point has been passed and a majority of content being generated online within the internet is now synthetic. Organic content generation simply cannot keep up with the flood of synthetic content. Those bot farms creating content never sleep. They just churn out content and pretend that it remains evergreen. My consideration on this topic started back on...

In the digital age, the methods we use to organize and comprehend information are continually evolving. Two significant approaches stand out: indexing facts and graphing knowledge. Both play essential roles in how we structure, retrieve, and understand data, but they serve distinct purposes and offer different advantages. Let’s start out by looking a little deeper into indexing facts. Indexing is...

You never really have to worry about how you store knowledge. All that knowledge just gets accumulated day by day and how it is stored, structured, and even retrieved happens without any intervention. It’s just something that you do autonomously. That is very different when you have to manage all that data and store it. Navigating the intricate maze of data science, structuring really large knowle...

Over the years the team over at Google has made a really big knowledge graph that you can access via an API and that they use as an informational backbone [ 1 ]. In some ways it is the best of what the old web had to offer. They note that it is a database of billions of facts. We are starting to see the creation of just a ton of middling, mediocre, or otherwise terribly written content online [ 2...

Things are starting to align within this renewed writing project as my content creation process gets back into some semblance of a proper routine. We are getting pretty close to a place based on the current state of technology where my weekly podcast audio could be produced using a model based on my voice in a matter of seconds. That is not really something that I am considering. I have recorded t...

Longtime readers of my work know that within my normative bias I tend to break things down into form, function, assumptions, and structure (FFAS). Instead of taking that path with this Substack based letter format, each week my commentaries are going to drift into a more ongoing narrative about the patterns, traditions, and concerns that rise to the forefront of my thoughts. All right, now is the...

It’s time to get ruthless about actually managing my epic writing backlog. You can rewind to a previous Substack newsletter with a search or for you subscribers you can check your previous email for the epic 2024 predictions post on January 19, 2024. That was according to my records the post for week 156. Instead of starting up a season two of the podcast I’m just going to lean into the signal of...
