Are tariffs bad for growth? Yes, say 5 decades of data from 150 countries (2020)
(sciencedirect.com)
Using an annual panel of macroeconomic data for 151 countries over 1963–2014, we find that tariff increases are associated with an economically and statistically sizeable and persistent decline in output growth.

DEDA – Tracking Dots Extraction, Decoding and Anonymisation Toolkit
(github.com/dfd-tud)
Document Colour Tracking Dots, or yellow dots, are small systematic dots which encode information about the printer and/or the printout itself. This process is integrated in almost every commercial colour laser printer. This means that almost every printout contains coded information about the source device, such as the serial number.

Matrix Profiles

Lately I’ve been thinking about time series analysis to aid in Reflect’s insights features. Towards this end, I’ve had a Hacker News thread about anomaly detection bookmarked in Later. I finally got to looking at it and there was a comment that mentioned the article left out matrix profiles, which I had never heard of, so I decided to look into them.

Some Reflections After a Month of Tracking My Own Online Activity
(mcwhittemore.com)
Since 8:38 PM on February 22nd, I’ve been recording all my browsing activity in a database I manage using a custom-built browser extension and a wrapper around @rosskevin/ifvisible. The result? I now have a clear picture of just how much time I’ve spent on the web this past month. And, well… I spend a lot of time reading email. Go figure.

Executive orders have been making the news recently, but aside from basic counts and individual analysis, it’s been hard to make sense of the entirety of all 11,000 accessible documents — especially for numerical analysis and trending. Thankfully we have LLMs to help with that.

The Deep Research problem
(ben-evans.com)
Most what I do for a living is research and analysis. I think of data I’d like to see and go looking for it; I compile and collate it, make charts, decide they’re boring and try again, find new ways and new data to understand and explain the issue, and produce text and charts that try to express what I’m thinking. Then I go and talk to people about it.
