Another C++ fail

Posted on February 29, 2024 by james

Oooh! C++20 has std::format that would allow me to easily format file modification times from std::filesystem/chrono. Oh, allegedly it does in MSVC and Clang, but not in the C++20 support with the GCC that’s part of Mint 21.3 or the … Continue reading →

Posted on February 23, 2024 by james

I’ve been lining up a possible new project today, thanks to stalling a bit on the work I was doing on Deep Sky Stacker. It’s more C++/Qt development, but in this case I thought I’d try to create the entire … Continue reading →

Pretty much anyone who is into amateur astrophotography will be familiar with Deep Sky Stacker (aka DSS). It’s a great application that takes combinations of light and dark frames (amongst others) and merges them to produce a single stacked output … Continue reading →

An unexpected ssh “gotcha”

Posted on December 24, 2021 by james

OWFS on a Raspberry Pi

Posted on January 29, 2020 by james

I have an old Raspberry in my Stevenson screen and I’d quite like to hook it up to my 1-wire weather sensors rather than running the 1-wire connection into the observatory to my desktop system there. OWFS looks like it … Continue reading →

Geeking out

Posted on January 15, 2020 by james

I’ve put quite a bit of time into oacapture and oalive this year and hopefully they’re the better for it, with a new release coming soon. Github demonstrates the depth of my efforts:

Missing icons in Kstars and Ekos

Posted on August 29, 2019 by james

After installing Kstars and friends on my Mint 19 desktop from the launchpad PPA, I discovered that none of the buttons in the application had icons. Some were blank, whilst others had text overlaying them. I only actually realised this … Continue reading →

Success with libgphoto2!

Posted on August 29, 2019 by james

Since the last release of oacapture I’ve mostly been working on oalive, an EAA-type application that will share a large amount of code with oacapture. One of the new things I wanted to do with this was to add support … Continue reading →
