Surely the crash of the US economy has to be soon
Last year I predicted there would be a significant (2008+) economic crash that year. The year is now 2026 and I was wrong. At the time my main argument was essentially this: The unemployment rate just follows these smooth curves, covid was an exception, and it was due to jump again. Not very scientific I […]

4x faster network file sync with rclone (vs rsync) (2025)
For the past couple years, I have transported my 'working set' of video and project data to and from work on an external Thunderbolt NVMe SSD. But it's always been slow when I do the sync. In a typical day, I may generate a new project folder with 500-1000 individual files, and dozens of them may be 1-10 GB in size…

Ratchets in software development (2021)
So there's a thing we use at work which I call a ratchet. In our codebase, there are "patterns" which we used to use all the time, but we decided to stop using them, but removing all of the existing instances at once is too much work. We want to remove all of these instances eve...

Is the RAM shortage killing small VPS hosts?
The AI surge has DRAM producers like Micron focus on HBM (High Bandwidth Memory) to serve AI hyperscalers over the DRAM (Dynamic Random Access Memory) used by ordinary consumers and small businesses. Consequently, for instance, servers which used to cost $2500 on Newegg now cost $5000. RAM alone is $2500 now.
