I really like the Crusader network test application for measuring network throughput and latency. It’s cross-platform and provides a useful reference for network measurements. But the macOS binary opens a Terminal window that’s confusing and “gets in the way”. Furthermore, you have to know which binary to use – Intel or Apple Silicon. I decided
I wanted to create a macOS bundle for an application that I use frequently, and wanted it to have an attractive icon. I had a good PNG image, and knew that there must be a way to convert it to the multiple sizes required by modern macOS. I found Ben Souchet’s png-to-icns repo that does
I’ve been following the progress of qStudio – a SQL IDE that runs on Windows, macOS, and Linux. It’s great for running SQL queries against a database. I haven’t used its Pulse features to create real-time graphs of live data, though. My use of qStudio is driven because it includes the PRQL compiler that takes
If you work much with OpenWrt, you likely have a pile of older routers that you’re no longer using. But what to do with them? You could pass them along to friends/family or even donate them to the local thrift store. But first you must solve a big problem… Read the README for more info….
@SiemusS recently asked me to review the draft documentation for FQ_CoDel for OPNsense. The document turned into a fairly nice description of the FQ_CoDel algorithm. See https://github.com/opnsense/docs/blob/master/source/manual/how-tos/shaper_bufferbloat.rst
We promise not to fix it if we don’t know it’s broke. My mentor at Dartmouth College, Stan Dunten, said this all the time. That’s why I always send in short reports to webmaster@…. mentioning something that didn’t look right. Most of the time it’s something silly. And sometimes I get a heartfelt “Thanks!” because
I often hear people saying they have bad responsiveness / high latency on their high-speed internet connection. Even though they have a contract for 500 mbps+ service from their ISP, a speedtest shows high ping times when the link is loaded. The answer is well-known – install a router with SQM that knows how to
Many people are surprised to hear that their web browsing doesn’t have to be crowded out by intrusive ads. There is an entire industry of “ad blockers” and “content blockers” that claim to fix this. uBlock Origin is the one I use. Its author, “gorhill” states that it’s Free. Open-source. For users by users. No
The NH Stone Wall Mapper project uses Lidar data to display small variations in ground elevation. A UNH project built this map to identify stone walls in the state. This site can be “misused” (in a good way) to show lots of other topographic features. Here’s a “Lidar view” of the grounds of Loch Lyme
A friend (thanks, Ted!) directed me to a nice science-based article that assigns some probabilities of risks of transmitting a disease like coronavirus. The author highlights two major scenarios: Warm body transmission: how far apart should you be from other people if you want to avoid transmission from another “warm body” Surface-based transmission: what precautions
