Adding Documents

Most of the time I add documents via their DOI. For example, I'll be on IEEExplore or ResearchGate and see a paper that I either want to read or know for sure I'll want to cite. So I simply copy the DOI and run

Resize Ghidra for High DPI screens

If you run Ghidra on a high DPI screen, you will probably find the GUI to be scaled down so small to be almost of no use.

There is a setting that you can adjust to scale the Ghidra GUI:

in $GHIDRA_ROOT/support is a file named launch.properties. In this launch.properties file is the following configuration key:

VMARGS_LINUX=-Dsun.java2d.uiScale=1

Enable persistent storage for the systemd journal log

Overview

The assumed default setting in /etc/systemd/journald.conf is Storage=auto which implies that systemd journaling will only persist the journal if the expected storage location is available. Otherwise, the journal data is stored in memory and lost between reboots. On Ubuntu 16.04, /var/log/journal does not exist by default. Create it to keep and query events from previous boots.

Considerations:

Syslog still provides the persistant log records for Ubuntu 16.04, so enabling persistant systemd journal logging does cause a level of duplicaiton.
There are sane defaults:

	function filter() {
	return this.id.includes("suggested") \|\| this.id.includes("mentioned") \|\| this.id.includes("supplementary");
	}

	function book() {
	patel = false;
	if(!patel) return $(this).children().eq(0).html().includes("Y.N. Patt and S.J. Patel");
	else return $(this).children().eq(0).html().includes("D. Harris and S. Harris");
	}
