No program to keep
There is no program on the ship to install, update or send a technician for.
At sea
Built for the link a ship really has: slow, shared, and dropping without warning.
Nothing to install on board.A browser on the ship's computer is enough.
No special computer
You do not need an expensive or special computer. PIRION works from any computer that runs a current browser.
Browsers
Specially optimized for Google Chrome and Apple Safari.
Ready for a tablet.A finger gets the answer a mouse would.
A closed button answers
A button you may not press stays on the screen. Press it, and a short message says why and who can take the step.
Made for a finger
Where a mark is picked, it is picked from boxes a thumb can hit. On a narrow screen, rows stack instead of running off the side.
Optimized for slow links.Few bytes, few round trips.
Opening
The application's files stay in the browser, and the screens of your work are fetched quietly in the background. The first screens are asked for together, not one after another.
Screens
Text travels compressed, and lists that rarely change are asked for rarely.
Coming back
A screen opened within the last half hour comes back from memory at once, then refreshes.
Long lists
A long list draws only part of its rows and adds more as you scroll. On the Due list, filtering happens in the browser, without asking the server again.
Photos
On photo fields, a large camera JPEG is redrawn smaller before it leaves the ship. Papers an agent has to read keep their full size.
Uploads
An upload shows how far it has got, in percent and in megabytes. If no byte moves for a minute, it is tried again.
A dropped link leaves no double record.Press once, and carry on with the work.
While saving
When the link drops during a save, the same save is tried again by itself. The screen says "Connection is unstable — still trying to save…", and a Stop button stays beside it.
A lost answer
When the save arrived but the answer was lost on the way back, the server recognises the repeat and returns its first answer. No second record is written.
A second press
A form keeps its draft number through a reload or an expired session. If the first save had landed, the person is told: "Your first save had already arrived".
An agent's run
When the link drops and a request to an agent is sent again, the server recognises the repeat and goes back to the first run. The agent does not run twice, so nothing more is spent.
