Practical quantum computing and getting things done

The Lindahl Letter ·

2024/10/25

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 recording technique to deliver superior podcast audio. Last week we really dug deep into the major corporate

Digging into quantum computing programing

The Lindahl Letter ·

2024/10/18

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 computing power you are using to simulate the quantum computer has a very small fractional power equivalent in terms

The increasingly synthetic internet

The Lindahl Letter ·

2024/10/11

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 Wednesday, July 31, 2024, when I was invited to access SearchGPT from OpenAI [1]. Using that platform

Indexing facts vs. graphing knowledge

The Lindahl Letter ·

2024/07/26

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 a traditional and straightforward method. It involves categorizing and listing information in a manner

Structuring really large knowledge graphs

The Lindahl Letter ·

2024/07/19

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 knowledge graphs presents itself as both an art and a science. This endeavor, crucial for deepening our

Increasingly problematic knowledge graph updates

The Lindahl Letter ·

2024/07/12

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][3]. Now imagine you had built a knowledge graph of billions of facts. You can’t stop updating that large

The next level of featurization

The Lindahl Letter ·

2024/07/05

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 the last two podcast episodes using my newly acquired MacBook Air using the freely supplied GarageBand

All the future AI features

The Lindahl Letter ·

2024/06/28

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 time, let’s jump into that narrative at the deepest end of the things being considered. Maybe the theme

You can’t stop the signal

The Lindahl Letter ·

2024/06/21

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 things and publish this missive as week 157 of the Lindahl Letter. For those of you who are new to this

3 years on Substack

The Lindahl Letter ·

2024/01/13

Please accept this note of gratitude for being a part of this journey. We made it. Some of you have been a part of the entire journey. Three years ago on January 26, 2021, this very Substack started rocking and rolling along a weekly journey to share research notes. My backlog of weekly items to cover is still pretty darn larger. It contains well over 100 blocks of potential writing content. A few larger projects are lurking within that backlog that could be stacked up block by block into future

Bayesian Models and Elections (150th post)

The Lindahl Letter ·

2023/11/18

Maybe a longer title for this post could be, “Bayesian Models and Elections: A Dive into the Dance of Uncertainty.” This is the 150th transmission of the Lindahl Letter.In the vast and often unpredictable theater of electoral forecasting, the quest for precision is a relentless pursuit. The choreography of voter behavior is a complex ballet, orchestrated by a myriad of factors—societal tremors, economic tides, the charisma of candidates, and the machinations of campaign strategies. Amidst this

Title: The Confluence of Agent Systems and Expert Opinion in Election SimulationsIn the ever-evolving landscape of political science and technology, curiosity often paves the way for innovative approaches and fresh perspectives. Recently, a wave of curiosity has washed over me, primarily centered around the exploration of diverse agent systems to simulate elections. This intersection of technology and electoral processes opens up new realms of possibilities, allowing us to mimic, analyze, and

Let’s get to work unpacking the Delphi Method & Door-to-Door Canvassing. This is the Substack deep dive you don’t want to miss.Hey there, dear weekly Substack readers!Today, let's embark on a journey through two fascinating potentially election related realms: the Delphi Method and Door-to-Door Canvassing. While these two concepts might seem worlds apart, there is a curious intersection between the two of them that's worth exploring. So, grab your favorite beverage, and let's dive in! I had two

Knowledge graphs vs. vector databases

The Lindahl Letter ·

2023/10/27

Don’t panic, the Google Scholar searches are coming in fast and furious on this one [1]. We had a footnote in the first sentence today. Megan Tomlin writing over at neo4j had probably the best one line definition of the difference by noting that knowledge graphs are going to be in the human readable data camp and vector databases are more of a black box [2]. I actually think that eventually one super large knowledge graph will emerge and be the underpinning of all of this, but that has not happened

Synthetic social media analysis

The Lindahl Letter ·

2023/10/20

After the adventures of last week, I started this writing adventure wanting to try to figure out what people were doing with LangChain and social media. People are both generating content for social media using LLMs and oddly enough repurposing content as well. We have to zoom out for just a second and consider the broader ecosystem of content. In the before-times, people who wanted to astroturf or content farm had some work to do within the content creation space. Now ChatGPT has opened the door

Learning LangChain

The Lindahl Letter ·

2023/10/13

And now it’s time to pivot toward the “Learning LangChain” topic…The most fun introduction to LangChain seems to be from DeepLearning.ai with Andrew Ng and Harrison Chase [1]. You can expect to spend a couple of hours to complete the process of watching the videos and absorbing the content. Make sure you use a browser window large enough to support both the jupyter notebook and the video. You are probably going to want these items to run side by side. This course covers models, prompts, parsers,

Building generative AI chatbots

2023/10/06

You can feel the winds of change blowing and the potential of people building out election expert opinion chatbots. Maybe you want to know what they are probably going to use to underpin that sort of effort. If you were going out to build some generative AI chatbots for you might very well use one of the 5 systems we are going to dig into today.* Voiceflow - This system may very well be the most prominent of the quick to market AI agent building platforms [1]. I have chatbots deployed to both Civic

Proxy models for elections

The Lindahl Letter ·

2023/09/29

Sometimes a simplified model of something is easier to work with. We dug into econometric models recently during week 136 and they can introduce a high degree of complexity. Even within the world of econometrics you can find information about proxy models. In this case today we are digging into proxy models for elections. My search was rather direct. I was looking for a list of proxy models being used for elections [1]. I was trying to dig into election forecasting proxy models or maybe even some
