I do not find it more simple, parse has very simple to use, time-saving, client side libraries. PostgREST does not seem to have anything close to that. There seem to be 3rd party c…

Good job man. I have used inkscape in these kind of tasks, but it seems that with every new version, it sucks even more. Seeing these kind of web apps is refreshing! Just some feed…

We will never get around replacing old industrial interfaces like Modbus, because there are simply too many and because people still use them in new applications because better the…

I use this at pidtuner.com to calculate Jacobians. But beware, nothing beats analytic derivatives. Depending on the languague and requirements needed to implement a given algorithm…

just open the window in incognito using a VPN to a country with a weak currency and to get 90% discounts on 30% of the original value.

I prefer Armadillo because of the Matlab-like syntax that feel like writting down the equations as they are in pencil and paper. Much more readible: http://arma.sourceforge.net/doc…

I have given WSL2 a chance recently and it sucks, the vmmem process eats all my memory. It is not a recent bug, it has been known since 2019 and hasn't been fixed. Beware: Don't lo…

A guy that has no time for philosophy.

I run https://pidtuner.com - GNU Octave for development and testing - Emscripten, Armadillo and C++ for deployment code - Static html, css, js (bunch of libs) - Github for main hos…

A PID tuning guide with almost no math. But very important thing to consider when making an system identification test indeed.

I like that it has no math or equations, only practical tips.

Useful if you need to adjust the PID gains https://pidtuner.com

LQR does not include integral action by default

Not sure I can (legal reasons?), but suffice to say thay feed multiple stations with multiple relatively large machines (+10MW). In some cases they have daisy-chained basins, so th…

For me the most complicated part when doing manually was the delay, because the water from the intake gates do not reach the headponds inmediatly. What I like is that the tool cons…

I have used this tool to tune the water level PIDs of several hydroelectric substations. I passed from spending days with manual fine tuning to a couple of hours of a simple experi…

Thers is this tool whole algorithms were originally implemented in C++ to use in industrial applications. But was easily ported to the web to create a PWA that now anybody can use.…

It is athough question, given that C++ is multi paradigm and recently changing a lot (last 10 years). There is: * Classic C++ (before C++11) * Modern C++ (after C++11) * Object ori…
