| !! Text summary |
| Text summary |
| Summarize big documents visually |
| *thumbnails per page (section?) |
| *identify important words, assign colors, show them on reduced representation of doc (a couple pixel per page) |
| *when zoomed in show sentences that are important |
| *could apply to websites, clusters of docs etc. |
| !!!Application idea |
| !! Trace viewer |
| Goals: |
| * View strace, truss |
| * Focus on single line records but be ready for multi-line |
| * Display text as-is or parsed into columns |
| * Try to have light weight classes (point to records) |
|
| Columns: |
| * Time |
| * Pid/thread id |
| * Name of syscall |
| * Args |
| * Result |
|
| Sort by: |
| * Time |
| * Pid/thread id |
| * Syscall |
| * Args (textually, useful for file names) |
| * Result (useless?) |
|
| Filter by: |
| * Time |
| * Pid/thread id |
| * Syscall (list of names?) |
| * Args (substring, regexp?) |
| * Result |
|
|
| Actions: |
| * on pid/thread id |
| ** show command (if possible) |
| ** set filter to exclude/include |
| ** if still running: pstack, attach dbg, jstack, memory use |
| * on syscall: |
| ** man page |
| ** set filter to exclude/include explicitly |
| * on args |
| ** set filter to exclude/include with text under cursor as default value |
| * on result |
| ** set filter to exclude/include |
| ** explain value |
|
| Graphs: |
| * time |
| * name of call |
| * values |
| * args: checksum of text, extract from text |
|
|
| General types: |
| * number |
| * time |
| * text |
|
| Additional fields: |
| Use cases: |
| * where is the app looking for that file? |
| * what is taking time? |
| * find string in read or write, identify the file (previous open that returned the file descriptor) |
| * find sigsegv |
| * find children spawned |
| * pid to execve command |
| * find errors (system calls return error code, child processes returning error codes) |
| * timing graph (time, pid or system call time) |
| * show network connections? |
| * show open files? |
| * bookmark position |
| * take snapshot |
| * copy paste |
| * jump to other process talking to this one (port number, lsof, pid, strace) |
| * open multiple strace commands, merge in one view |
| * load multiple files, merge (time) |
| * diff (ignore time) |
|
| !!!Implementation techniques |
| * Use composition to display image background behind widget: [swing | http://www.java-tips.org/java-se-tips/javax.swing/wrap-a-swing-jcomponent-in-a-background-image.html] |
| * glazed lists seem interesting for searching/filtering lists |
