Spooky Halloween edition: When Satoshi-Era Wallets...

The Lindahl Letter ·

2025/10/31

Happy Halloween everybody! Thank you for tuning in to week 211 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “When Satoshi-Era Wallets Wake Up.”Seriously, Bitcoin is weird. It has an enigmatic and anonymous founder. The origin story of how this cryptocurrency came to be is pretty much ineffable. Roughly a third of all bitcoin has never moved [1].These dormant or maybe abandoned coins shape both the scarcity

2025/10/24

Thank you for tuning in to week 210 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “AI Is Burning Through Graphics Cards.”Generational wealth is being invested into data centers for AI. It’s so prevalent that you hear about it on the nightly news and municipalities are dealing with the power demands. The clock is ticking on graphics cards being used for AI inference. The current generation of GPUs was never

2025/10/17

Thank you for tuning in to week 209 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Social media stopped being social.”Before we get going this week. I need to provide an update about last week’s post. I take full responsibility, as the principal writer here, that last week my writing efforts were just not up to par within the 208th Lindahl Letter publication. You have come to expect better from me and last

Building with constant model churn

The Lindahl Letter ·

2025/10/10

Day after release update: I guess it was the 208th post where we hit the proverbial wall with a dud of a post. This post in retrospect turned out to be one of my weaker efforts. I thought it was a strong take about dealing with the rate of change in model development, but it was just not focused and targeted based on delivering quality and insights.Thank you for tuning in to week 208 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for

Enforcing AI standards without exception

The Lindahl Letter ·

2025/10/03

Thank you for tuning in to week 207 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Enforcing AI standards without exception.”Standards are something we need to spend more time talking about. That is a general statement and not a special argument. Years ago, I actually witnessed a physical desk sign at an office that said, “We either have standards or we don’t.” It’s not a great mystery how that particular

The Great Tokenapocalypse

The Lindahl Letter ·

2025/09/26

Thank you for tuning in to week 206 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration is “The Great Tokenapocalypse.”As large language models reach deeper into consumer devices, the cost of running them becomes the real bottleneck. So many tokens get burned with no ROI or use case for the company burning them; it's really out of control. Almost as out of control as the sunk cost of data centers that will probably be regretted at some point

Apple’s Hidden AI Strategy

The Lindahl Letter ·

2025/09/19

Thank you for tuning in to week 205 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Apple’s Hidden AI Strategy: Waiting it out with token avoidance as a first principle.”Apple’s relative restraint in deploying large-scale generative AI isn’t just about privacy posturing or design philosophy. Maybe it is just the latest supply chain management initiative in terms of managing tokens. It may reflect a deliberate

Context window garbage collection

The Lindahl Letter ·

2025/09/12

Thank you for tuning in to week 204 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Context window garbage collection.”Here we are this week contemplating how to clean up the mess from all these celebrated LLM chat sessions. It’s a disjointed mess that lacks federation or dare we say portability. We are at the point where we need to think about how context window garbage collection explores the deeper process

Portable knowledge sharding

The Lindahl Letter ·

2025/09/05

Thank you for tuning in to week 203 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Portable knowledge sharding.”The shards of knowledge that we need are everywhere. They are just not portable and all packaged up. You open an interaction with an LLM based on a prompt, but you don’t really close it out by receiving a prompt or a packaged transferable output. This week’s focus is on how knowledge can be broken

Personalized context bubbles

2025/08/29

Thank you for tuning into the podcast. This is week 202 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Personalized context bubbles.”Last week we took a deeper look into content window fragmentation. That is just the right amount of foundation to start to consider personalized content bubbles. Don’t panic; no foundation model pun intended. I even talked about it on YouTube during a recent Nelscast episode. It

2025/08/22

Thank you for being a part of the adventure. This is week 201 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “Context window fragmentation.”Exactly. You are either aware of or have felt the effects of context window fragmentation. I thought this topic would be a really sharp angle for consideration. Something that would stand out and be interesting as a point of conjecture. Instead of just digging into the

Thank you for tuning in this week. Not only will this not be an audio only presentation this week and you will have to check YouTube at some point in the not so distant future for more details on that, but also I have tweaked the noise gate in GarageBand to improve the overall audio quality. This is week 200 of the Lindahl Letter publication. A new edition arrives every Friday. This week, the topic under consideration for the Lindahl Letter is, “My 200th Lindahl Letter Explained.”My very first

Thank you for tuning in to this audio only podcast presentation. This is week 193 of the Lindahl Letter publication. A new edition arrives every Friday. This week the topic under consideration for the Lindahl Letter is, “A 56 day posting break.”Over the last 4 years, the Lindahl Letter has taken two pretty decent breaks in posting content. This last pause in posting happened to be the most recent 56-day posting break. Maybe this (right here, right now) is a good point in the process to refocus,
