The move was driven by several factors, including a steep learning curve and maintenance complexity associated with Druid, cost considerations, and ClickHouse's better alignment with Lyft's infrastructure and engineering expertise. ClickHouse's benefits included simplified infrastructure management, a reduced learning curve for engineers, native data deduplication support, lower costs compared to Druid, and specialized functionalities that made various tasks easier.

Managers who continue thinking about work after hours may actually harm their leadership performance. A study found that not taking a break from work in the evening, especially for new managers, drained their mental resources and reduced leadership effectiveness.

04MISCELLANEOUS

WILL US COMPANIES HIRE FEWER ENGINEERS DUE TO SECTION 174?

US software companies, particularly smaller ones, are facing unexpected high tax bills due to changes in Section 174 of the US tax law. This change requires R&D costs, including software engineer labor, to be capitalized and amortized over 5 years (or 15 years if labor is done outside the US). As a result, companies have to pay taxes on profits they technically haven't realized yet, leading to layoffs and reduced hiring of software engineers. Large tech companies are able to manage the tax increase better than startups.
