Well, there are two good options: Use the Unicode characters for mathematics in simple one-line formulas and then add the Greek keyboard for things like pi or π by using the Globe icon 🌐 to switch to Greek and type a p. On a Mac, you get these with CTRL-CMD-Space…

Well, I’ve been putting off buying a new Apple Watch for years. We got the first Series 1 and it was hard to figure out what to do with it (this was before it became more fitness-focused and was supposedly a general application and notification platform). Like all first versions,…

OK, it’s been three long years since I’ve used a dedicated bare-metal Ubuntu machine. The last time was with house-made machine learning machines when the Titan was a big system, but we were amongst the first to build quad GPU machines running the then very new Ubuntu 14.04. Now of…

That’s because most Dockerfile do not have pinned dependencies: This is a simple example that starts ubuntu, installs some…

Well, now that world has moved so far over to USB C, there are so many more choices of chargers. You can get a USB C charger with 200W and multiple connectors, but it is super confusing what works with what. And when you plug multiple devices in, how much…

This is one of the more confusing aspects of WordPress. Yes, I know, I’ve transitioned all the sites that I own to Hugo (except for tongfamily.com and calvintong.com), but I’ve been stuck on WordPress for a simple reason. Editing a Hugo site is a big pain. There is supposed to…
