be defined as the human activity directed toward the advancement of knowledge, where knowledge is of two roughly separable sorts: 1) facts or data observed in reproducible experiments and 2) theories or relationships between data.” —Richard R. Nelson. “The Simple Economics of Basic Scientific Research”. In: Journal of Political Economy 67.3 (1959), pp. 297–306. doi: 10.1086/258177
capable of finding user IDs by their names.” use std::collections::HashMap; let mut map: Map<String, i16> = HashMap::new(); map.insert("Jeff".to_string(), 42); map.insert("Lucie".to_string(), 17); // +N more items here let id = map.get("Jeff"); RQ: “Whether HashMap is the best possible map implementation for N < 20?” Answer: https://github.com/yegor256/micromap New implementation, based on the law of nature just discovered: use std::collections::HashMap; if (N > 20) { map = HashMap::new(); } else { map = micromap::Map::new(); } 6/29 March 13th, 2026 @yegor256
“The lifetime return to publication of the first article for an assistant professor is $12,340 $71,928 (in 2026). The returns to additional publication diminish rapidly at first but at a lesser rate as the number of publications continues to increase.” Source: Howard P. Tuckman and Jack Leahey. “What Is an Article Worth?” In: Journal of Political Economy 83.5 (1975), pp. 951–967. doi: 10.1086/260371
from three separate state university systems, each comprised of research-focused institutions, we find that the marginal impact of an additional academic publication on a scholar’s citations increases that scholar’s pay by anywhere from 2.8 to 8.9%.” —João Ricardo Faria and Franklin G. Mixon Jr. “The Marginal Impact of a Publication on Citations, and Its Effect on Academic Pay”. In: Scientometrics 126.9 (2021), pp. 8217–8226. doi: 10.1007/s11192-021-04073-z
“At a level of zero citations, the marginal value of a citation to a nonfirst-author article is $314 $899, while that of a citation to a first-author source is $402 $1,150.” Source: Arthur M. Diamond. “What Is a Citation Worth?” In: The Journal of Human Resources 21.2 (1986), pp. 200–215. doi: 10.2307/145797
mean lower quality? Caitlin Sadowski “A correlation between change size and review quality is acknowledged by Google and developers are strongly encouraged to make small, incremental changes (with the exception of large deletions and automated refactoring).” —Caitlin Sadowski et al. “Modern Code Review: A Case Study at Google”. In: Proceedings of the 40th International Conference on Software Engineering: Software Engineering in Practice. 2018, pp. 181–190. doi: 10.1145/3183519.3183525
methods are code smell? “We analyzed 605,966 Java methods from 109 public repositories and found a moderate correlation between NoBL and complexity metrics such as LoC, HSV, HSE, and NCL, along with a positive non-linear relationship with MIDX.” Source: Rusland Galiulin and Yegor Bugayenko.

First Paper: 1) Read the book Write for Computer Science by Zobel [12]. 2) Read the book about L A TEX by Lamport [8]. 3) Subscribe, for example, to the SEWorld mailing list. 4) Find a venue at yegor256/awesome-cfp. 5) Find a professor to supervise your writing. 6) Write it up, using the Research Flow process. 7) Submit and wait for 2–3 months.
a free enterprise economy to underinvest in invention and research (as compared with an ideal) because it is risky, because the product can be appropriated only to a limited extent, and because of increasing returns in use. This underinvestment will be greater for more basic research.” —Kenneth Joseph Arrow. Economic Welfare and the Allocation of Resources for Invention. Springer, 1972. doi: 10.1007/978-1-349-15486-9_13
importantly, in practice 50% or more of R&D spending is the wages and salaries of highly educated scientists and engineers. Their efforts create an intangible asset, the firm’s knowledge base, from which profits in future years will be generated. To the extent that this knowledge is ‘tacit’ rather than codified, it is embedded in the human capital of the firm’s employees, and is therefore lost if they leave or are fired.” —Bronwyn H. Hall. “The Financing of Research and Development”. In: Oxford Review of Economic Policy 18.1 (2002), pp. 35–51. doi: 10.1093/oxrep/18.1.35
