In 2020, I surveyed the darktable user base and published the results1 : a population of male engineers and scientists, more educated and vastly more computer-literate than the general population, with close to no women and few professional photographers.

It’s been a bit more than one year that I have put Chantal AI online, with now 3 major iterations of design.

In the strange, pathetic society we live in, avoiding fight and conflict at all costs is often mistaken for being empathetic, and the woke bullshit has even made it a virtue.

This is a follow-up on the previous Websites suck, which covered the preliminary information retrieval step.

The silver halide film grain has an unique look that introduces some texture in smooth image areas, where digital imagery may look synthetic and too clean.

I have spent the past month working on an AI-based search engine.

The core basics of design are to know for whom you design, that is who are the users of your solution, what they expect and what they need.

There is this mantra that I have been hearing too much in my life : “don’t reinvent the wheel”.

The FLOSS applicative ecosystem is moved by an ideology of freedom and privacy.

In image processing, retouchers may want to apply a saturation boost on specific hues only.

There is one thing you will find on the home page of pretty much any open source (call it libre or free if you will, those lines are blurred) image editing software : the promise that it is, somehow, suitable for professionals.

The saturation control of pretty much all image processing software is an unfortunate misnomer, to say the least.

I’m a responsible web designer, and as such, since WordPress (finally) accepts media uploads of image/webp MIME type and since all web browsers  newer than september 2020 (even Apple Safari \o/) can display it, I have been moving my photos library to WebP…

This page is inspired by the Munsell book of color.

WP Scholar provides a clutter-free, direct and fast typing experience for the heavy-duty writers who type a lot every day (technical writers, engineers, analysts, journalists, researchers, scientists, etc.) and are stuck with WordPress as a CMS.

The Laplacian operator $\Delta u$ is the divergence of the gradient, that is the sum of the second-order partial derivatives $\nabla^2 u$ of a multivariate function, which represents the local curvature of this function.

Among the technical fields, quite a few have the potential to harm the public : the first that come to mind are medicine and civil engineering.

As a designer, your job is to match someone’s needs/problems with a solution.

If you are working in image processing and using Python as a prototyping script language to test algorithms, you might have noticed that all the libs providing fast image interpolation methods (to either sub-sample or over-sample) work in 8 bits unsigned…

Following my work on the filmic tonemapping, several users have reported issues with very saturated blue areas (stage spotlights, bright skies) and red areas.

Darktable  is an open-source software for raw photographs management and processing developped since 2009 for Linux desktops.

I have been using WordPress as a CMS (content management system) for almost 10 years now.

I have struggled with most solutions to convert and embed Jupyter notebooks into WordPress blog posts since I use Plotly as a graphic lib, as well as many LaTeX equations and images.

Introduction¶General goal¶The design of a camping van involves an estimation of the heat losses that will lead to the subsequent design of both the insulation and the heating system.

A few weeks ago, I discovered the tiny world of tiny houses and camping-vans and found that quite amazing.
