The Buy and Hold Mindset
When markets are in turmoil, like they have been for most of this year, I like to have a buy-and-hold mindset when it comes to making new investments. It is hard to know when you’ve reached the bottom and can start buying again, but if you think about a ten or twenty-year hold, then it […]

Protect me from what I want
Over on Mastodon, there are many people who enjoy not being in the grip of software like Facebook or Twitter that single-mindedly tries to maximize “engagement”, which means the amount of time you stare at the screen so they can show you ads.

How thick is a three-sided coin?
Matt Parker, employing the enviably pithy prose typical of a content creator forged on the unforgiving fires of social media, asked the simple question back in 2018: > How thick is a three-sided coin? Translated into mathematician-ese, this means > What aspect ratio of a flipped coin leads to the chance of landing on…

Everything I wish I knew when learning C
Learning C was quite difficult for me. The basics of the language itself weren’t so bad, but “programming in C” requires a lot of other kinds of knowledge which aren’t as easy to pick up on:

SwiftUI Is Convenient, but Slow
I've been sitting on publishing these notes for a while, because I don't want to diminish the work of the talented people that engineered SwiftUI and plowed through years of AppKit and UIKit code to get to this state. But I'd like to draw attention to some performance limitations, in the hope that a SwiftUI engineer…

Git Notes
the short of it is: they’re cool for appending notes from automated systems (like ticket or build systems) but not really for having interactive conversations with other developers (at least not yet)

The entire crypto ecosystem is a ponzi
Not really. As a counter example, gold is clear and very old ponzi. It's ok. And as a more general argument, crypto does have utility. For circumventing capital controls, buying drugs or laundering money. So there will be constant supply of new depositors who needs that and willing to pay. I would not bet on crypto…

Emacs Lisp shorthands as namespacing system
In Emacs version 28 Emacs developers introduced so-called read symbol shorthands. If you’re interested in the rationale, feel free to search the Emacs developer mailing list for the discussion. However, it does seem that not everyone likes the idea of shorthands as a substitution for namespaces (or packages, if you’re…

Index Merges vs. Composite Indexes in Postgres and MySQL
Composite indexes aka multi-column indexes are about 10x faster than index merges. In Postgres, the gap is larger than in MySQL because Postgres doesn’t support index-only scans for queries that involve index merges.
