Salpa v0.3.1

Desktop application for visual scientific workflows.

Available Downloads

macOS

Installation note for macOS: the app is signed with a Developer ID and notarized by
Apple. Drag it to Applications, then open it — macOS will ask once whether you are sure,
because you downloaded it from the internet. Click Open. That is all.

Do not run xattr -cr. Earlier notes advised it, from when these builds were
ad-hoc signed and macOS refused them outright. Stripping the quarantine flag from a
properly notarized app gains nothing and skips the check that would tell you the download
was tampered with.

Windows

Installation note for Windows: SmartScreen may warn about an unrecognized publisher. Click "More info" → "Run anyway" to proceed.

Linux

Installation note for Linux: an AppImage needs two things a download does not give it.

chmod +x Salpa-0.3.1.AppImage      # a download is never executable
./Salpa-0.3.1.AppImage

If it will not start and says something about mounting, you need FUSE — not installed by
default on Ubuntu 22.04 and later:

sudo apt install libfuse2

Both failures are silent in the same way: nothing happens, and no error names the cause.

First launch takes a while

Salpa builds a Python environment the first time it runs. Measured on wiped machines with
nothing cached:

time until usable
macOS (Apple Silicon) ~30 seconds
Windows ~1.5 minutes
Linux ~2.5 minutes

The window can look idle while this happens. It is working — give it the time above before
concluding it has hung. Later launches are immediate.

Known Issues

  • Windows and Linux builds are unsigned. Windows SmartScreen will warn about an
    unrecognized publisher (see above). macOS is signed and notarized.
