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
I do a lot of work with spreadsheets. Some are pretty simple, and I can inspect them by hand. Some are enormously complicated – hundreds of rows, dozens of columns, etc. It’s not practical to inspect/test them manually. Enter ExceLint. It’s an add-in to Microsoft Excel that “lints” a spreadsheet. (A “linter” is a program
The PRQL project provides a simple, powerful, pipelined SQL replacement. To make it easier to share the development environment, there is a Dev Container that bundles the dozens of components into a single container. This makes it easier for new person to start using the project: they don’t have to collect the proper (sometimes conflicting)
As we take a shot at opening people’s eyes to bufferbloat, we should know some of the “objections” we’ll run up against. Even though there’s terrific technical data to back up our research, people seem especially resistant to thinking that bufferbloat might affect their network, even when they’re seeing problems that sound exactly like bufferbloat
I regularly record public meetings in my town and post them on Youtube. This allows residents who could not attend the meeting in person to see what occurred. It also supports creation of accurate minutes. I like to add a label (showing the committee name and date) and a timecode (a running clock showing the
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
