Sometimes

Try changing cables and network equipment to see if that’s the issue

Text

Text is quite hard to read, partly because it is flickering unless very imprecise.

It is easier to read text drawn a few letters at a time.

Implement functions for drawing a text message over time, a few letters at a time

All the letters

Optimisations

Limit the number of user event texts

Check the maximum number of text messages possible

Player trail flickering

Add off time on laser text for the zoomed out view

Activity points

Limit number of activity points to improve speed

If there are too many points already, maybe some points can merge into one bigger point?

Draw activity points as points

Drawing points instead of circles is waaaay faster.

User views

Fix user move coordinate

Show all user events separately

Ftrace visualisations

Many very short dots, one long dot in the middle

Colour code error codes

Something rising from the bottom up

System calls Some analysis (process? type?)

Walk across the screen

Similar types of events start close to each other small subset of types

ftrace event types

prefixes

ys, dd, ix, cp, redit, random,

There is probably one letter missing from the parsing in many of these

• ys: sys
• cp: tcp
• dd: add? (mostly random events)
• ix: irq_matrix
• redit: credit (random event)

Transitions between states

Maybe spin around at the end to reveal like the inside?

Looks good on the laser!! I need to fix the issue with zooming into/out of a specific spot.

Spin around to switch between states for the same position

Automatic transitions

Automatically connect and arm laser on startup

Find Etherdream automatically

This is the only part left, try it with the box.

View ideas

Let scrolling text from events fly across the screen

More details about the architecture in the zoomed out view

More details could be optionally drawn on the same view

• Different connected users (who have made an action in the last n seconds)
• Different parts of the server structure
• Different parts that are in the room (laser, DAC, webcams, server, projector)

NO Rain of ftrace events

Different colours for different events Tested: doesn’t work, the laer doesn’t have time to draw them and the colours don’t work with low intensity dots.

HOLD Stack trace like view?

HOLD Heartbeat monitor for events

User view for events per user

One colour per source of data

• users
• server
• room and OS

More events in the web server view

Server lines

• full line turning on per event, or
• a dot running horizontally

Documentation

Pause function for creating stills

• don’t run update
• don’t accept new events

Knowledge Base

Dot intensity

It seems like the maximum dot intensity is approximately 1.0 / (number_of_dots * 4)

From test

Disable vis being transitioned from because it becomes too bright when it’s tiny

Try to get rid of the flickering

• many users on red dots
• web ser er circle?
