‘Every time we say yes to a request, we are also saying no to anything else we might accomplish with the time’ Every year I seem to have the same resolution: say “no” more often. Despite my black belt in economics-fu, it’s an endless challenge. But economics does tell us a little about why “no”…

The ultimate productivity hack is saying no. Not doing something will always be faster than doing it. This statement reminds me of the old computer programming saying, “Remember that there is no code faster than no code.” The same philosophy applies in other areas of life. For example, there is no meeting that goes faster […]

We’ve all been in the awkward situation of meeting someone new and having to build rapport quickly. If you’re like many people — especially most Americans — you break the awkward silence with a pretty standard question: “So, what do you do?” But that question might not be the best way to build rapport with someone else. In fact, it may be best to avoid talking about work entirely if you want to really build trust with people. Research shows that when we have information on people from multiple contexts, we like them more. So instead of defaulting to work questions, ask them about hobbies, charities they support, where they grew up, or even who their favorite superhero is. You’ll definitely have a more interesting conversation, and you might

Reprint: R1311L The prevailing wisdom says that negative thoughts and feelings have no place at the office. But that goes against basic biology. All healthy human beings have an inner stream of thoughts and feelings that include criticism, doubt, and fear.

Let us not beat around the bush: Rust is not easy to learn. I think it took me nearly 1 year of full-time programming in Rust to become proficient and no longer have to read the documentation every 5 lines of code. It&#39;s a looong journey but absolutely worth it.

Rust takes a loooot of time to compile, even with incremental compilation. It&#39;s not rare that a small change leads to 2 or 3 minutes of compilation to test the change, which frustrates a lot of new rustaceans. It&#39;s a deliberate choice made by the language designers to favor runtime
