ABSTRACT

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.

Not quite as funny as the University of Alabama betting scandal getting found out by a guy going into a sports book and being like "no no I have insider information" but I am not surprised that this got revealed because the NBA actually tries to keep an eye on gambling behavior re: players/coaches.

We just spent 6 months to add 1 figure to this paper. Some people said, "Couples aren't prioritizing men's careers. Men just have better earnings opportunities when moving." Earnings effects of moves for couples on the left, singles on the right. Negligible gap between single men and women.
Event study coefficients that show that men's earnings rise more than women's among couples following a cross-commuting zone move (left panels). The pattern is muted or reverses among single men and single women (right panels).

I encourage people to watch this video. The selected footage shows the professor doing nothing even slightly out of line, whereas the student misinterprets the law and hopes to impose her religious beliefs on the material. Administrators caving to this is terrifying.

Finally solved the #Degoogling debate. Anyone who finds fault with this list = Skill issue.
The meme humorously suggests using Vim, a text editor, as an alternative to various Google services. Each Google app is paired with the Vim icon, implying that users can replace these services with Vim for a more privacy-focused approach, even for tasks typically handled by apps.

When you look at Bluesky activity stats, things aren't great. But bots have gotten worse here in my experience, and so I can't help but wonder what "actual" activity metrics would look like.
