? The difference between Executing and Executing in Terminal is that the later does what it says, opening a terminal shell, and from there, opening the desired application.? In practice, the only advantage of opening with the terminal is that you get to see any errors or diagnostics that the application logs to standard out, and can easily kill the program if the window goes away but doesn't fully exit.? The disadvantage is that you have another program running (the terminal shell), which could be a problem if you're constrained on RAM memory space.? It's also extra screen clutter.

Command-line applications, i.e. ones that don't open a GUI window, need to be run from a terminal shell.? YAAC isn't such a program.? Unless you need the terminal window for some reason, just choose Execute.

I created a desktop shortcut.? Works great.? When I click it it gives me two options, Execute or Execute in Terminal.
Both options seem to work.? What is the difference between these options ?
Thanks

Did I need to install a plugins or where exactly is that Memory Bar and garbages icon? Can’t find where or what to enable.

?The memory bar shows how much heap memory is available versus being used in the Java virtual machine running YAAC. The bar's position shows the percentage of heap size that is currently in use for data and dynamically loaded code. The two numbers displayed in the bar are the used and total sizes of the Java heap (per-process memory inside the process).

YAAC keeps all received AX.25 packets in heap as raw and decoded objects until their expiration time (configurable in the expert-mode Configuration dialog), so if you have a long persistence time or are receiving a high rate of traffic, YAAC may run out of available heap and start thrashing the Java garbage collector in a desperate search to find unreclaimed unused heap memory. If this thrashing gets too severe, the Java runtime will automatically quit (under the assumption that a hostile application is attempting to bring down the system). Before this becomes critical, YAAC will start automatically reducing the packet retention time in an attempt to reduce the memory demand. If this can't resolve the problem, it is recommended that you run YAAC with an explicit larger heap size limit. However, with the newer releases of the Java runtime, this is generally not necessary, as the JVM will claim up to half the RAM on your system (oink!) if needed to meet the program's demands. If you don't have very much RAM in your system, you'll need to either add more physical RAM memory or change your YAAC settings to reduce the demand.

The button with the trash can icon allows you to force Java heap garbage collection. If you push it, you should quickly see a change in the memory bar, assuming that automatic garbage collection hasn't recently run already to free up any no-longer-used memory objects.

Again, this shouldn't be an issue, unless you are running on a RAM-limited computer, are processing an unreasonably large amount of traffic or persisting it for an excessive period of time, or are doing something RAM-intensive in YAAC such as importing an OpenStreetMap dataset from the original files (rather than using the pre-processed files I make available on my website).

Hope this helps.
