Retained Mode vs. Immediate Mode In retained mode, the graphics library exposes an API to the application for building/updating a scene. However, the graphics library is in charge of issuing drawing commands. In contrast, an immediate-mode API allows the application to issue the drawing commands. Retained-mode APIs abstract away initialization, state maintenance and cleanup, but uses more memory. Immediate-mode APIs allow for more targeted optimizations. https://reactjs.org/ is one of the more popular retained-mode web APIs....

Pagination with Relative Cursors Exposing pagination through URLs like example.com/items?page=25&limit=100 leads to SQL like SELECT * from 'items' LIMIT 100 OFFSET 2400;, which inefficiently goes through 2,500 records and discards the first 2,400. With relative cursors, we have URLs like example.com/items?limit=50&lastID=XXX, which leads to SQL like SELECT * from 'items' WHERE 'id' > XXX ORDER BY 'id' ASC LIMIT 50, and this is more efficient, assuming there are indexes for id....

Mergeable Replicated Data Types On a distributed system, each replica should [eventually] converge to the same state. Commutative Replicated Data Types (CRDTs) can accept updates and achieve consistent without remote synchronization. The Need for Commutativity Say we have a queue \( 1 \to 2 \). Suppose two replicas, \(r_1\) and \(r_2\), independently call pop(). Each replica will have \(2\) on their queue. However, on receiving an update that the other replica popped, each replica will call pop() to be consistent, thereby deleting \(2\)....

One can use curl -v <url> to see all of the redirections and cookies set. found that generating a tiny URL for Zoom links gives a URL that first goes to redirect.viglink.com. I tried this on https://tinyurl.com/yyte6pqv, which points to https://www.c13u.com/socioeconomics/2020-11-21-experiments-in-social-economics/, but didn’t observe any 3rd party cookies. tinyurl.com did set a cookie, but that’s probably expected. proposes Federated Learning of Cohorts, which aims to enable ad-targeting based on people’s general browsing interest without exposing the exact browsing history....

WWW ‘21: The Web Conference 2021 REST: Relational Event-Driven Stock Trend Forecasting REST, an event-driven stock trend forecasting framework, that overcomes two limitations of existing event-driven models. Models the stock context, and learns the effect of event information on the stocks under different contexts. Constructs a stock graph and designs a new propagation layer to propagate the effect of event information from related stocks. #stock-trend-forecasting #computational-finance #graph-based-learning The value of stock trend forecasting is not unanimous, e....

OCR tends to miss (sometimes) really important context. Make use of derived data, e.g. age at marriage, gender differences, mortality rates, mapping migrations, last names Don’t spend all your time cleaning data. Try a sequence of things, not one big idea. Don’t expect existing tools to do the whole job. All the while, building new tools is not as straightforward. Sample Digital Humanities Projects ORBIS by Stanford ....
