I haven't used a desktop email client in years. None of them could handle the volume of email I get without at least occasionally corrupting my mailbox. Pine, Eudora, and outlook have all corrupted my inbox, forcing me to restore from backup. How is it that desktop mail clients are less reliable than gmail, even though my gmail account not only handles more email than I ever had on desktop clients, but also allows simultaneous access from multiple locations across the globe?

People frequently1 think that I'm very stupid. I don't find this surprising, since I don't mind if other people think I'm stupid, which means that I don't adjust my behavior to avoid seeming stupid, which results in people thinking that I'm stupid. Although there are some downsides to people thinking that I'm stupid, e.g., failing interviews where the interviewer very clearly thought I was stupid, I think that, overall, the upsides of being willing to look stupid have greatly outweighed the d...| danluu.com

A question I get asked with some frequency is: why bother measuring X, why not build something instead? More bluntly, in a recent conversation with a newsletter author, his comment on some future measurement projects I wanted to do (in the same vein as other projects like keyboard vs. mouse, keyboard, terminal and end-to-end latency measurements), delivered with a smug look and a bit contempt in the tone, was "so you just want to get to the top of Hacker News?"| danluu.com
There are some pretty strong statements about types floating around out there. The claims range from the oft-repeated phrase that when you get the types to line up, everything just works, to “not relying on type safety is unethical (if you have an SLA)”1, "It boils down to cost vs benefit, actual studies, and mathematical axioms, not aesthetics or feelings", and I think programmers who doubt that type systems help are basically the tech equivalent of an anti-vaxxer. The first and last of ...| danluu.com
If I had to guess, I'd say I probably work around hundreds of bugs in an average week, and thousands in a bad week. It's not unusual for me to run into a hundred new bugs in a single week. But I often get skepticism when I mention that I run into multiple new (to me) bugs per day, and that this is inevitable if we don't change how we write tests. Well, here's a log of one week of bugs, limited to bugs that were new to me that week. After a brief description of the bugs, I'll talk about what w...| danluu.com
