Running 2560x1080 on LG 29UM57-P on an old MacBook Pro OSX El Capitan

Yes. A mid-2011 MacBook Pro running OSX El Capitan can drive a 2560x1080 monitor via HDMI. I was not able to get 60 Hz working. I am settling with 53 Hz. I tried many settings before finding something that works. The refresh rate seems fine to me. Maybe the text could be clearer but for a $200 monitor running this resolution, I'll take it. Apple MacBook 2015 retina resolution is 2560 x 1800. Consider buying a better monitor that may literally give you fewer headaches. Install  SwitchResX Follow the instructions for disabling SIP After rebooting, run SwitchResX via System Preferences Select your LG monitor Click Custom Resolutions Click the + icon  Enter these settings  ( source ) Exit SwitchResX and save Reboot Run SwitchResX via System Preferences Select your LG monitor Click Current Resolutions Select the 2560x1080, 53 Hz setting Enable SIP If you discover better settings, please leave a comment.

Use pstree instead of ps

pstree -alp This magic incantation displays the process list as a tree, showing process IDs (-p) and arguments (-a), on lines long enough to fully show all the arguments (-l). Make it part of your toolbox! You can remember this command via the phrase process-tree-Alps! You're welcome!

Monitor changes in available disk space

for (;;) {         @x = `df /common`;         @y = ($x[2]=~ /(\d+)/g);         $avail = $y[2];         if ($last) {                 my $delta = $avail - $last;                  print "$delta";         }         print $x[2];         $last = $avail;         sleep 5; }

An ingenious way to find Java on POSIX systems

This is Perl code. _java_bin returns the full path to the java executable. From http://search.cpan.org/~dolmen/DateTime-TimeZone-HPUX-1.04/lib/DateTime/TimeZone/HPUX.pm our @JAVA_HOMES = ( '/opt/java1.4', ); { my $_java_bin; sub _java_bin { return $_java_bin if defined $_java_bin; $_java_bin = ''; # Default value: java not found (false) foreach ( (map { ("$_/jre/bin/java", "$_/bin/java") } (exists $ENV{JAVA_HOME} ? ($ENV{JAVA_HOME}) : ()), @JAVA_HOMES, ), (map { "$_/java" } split(/:/, $ENV{PATH}) ), ) { next unless -x "$_"; $_java_bin = $_; last; } return $_java_bin; } }

Find the 10 largest directories on POSIX

This script outputs the number of 1,024 byte blocks consumed by each of the 10 largest directories in the provided directory, or in the current directory if no arguments are provided.

The Software Project Lifecycle

All projects follow the same lifecycle pattern, or theme. What varies from project to project is the amount of time between stages. Embryonic projects consist of presentations, problem statements, solutions, Slack workspaces, and other forms of optimism. We can do this! Infant projects consist of proof of concept prototypes built by at most three developers. There is no error handling. Baby projects have a source code repository and programming guidelines. It might be possible to run it on your own laptop. Fat chance. Toddler projects have automated builds and unit tests. They “go live,” always too soon. Tween projects have bug tracking systems. Users are unpaid testers. Teenage projects have a release candidate that evolves, usually much longer than anyone expects, into the sacred “one dot oh.” Most projects fail during this stage due to infighting or insufficient funds. The teenager ages into adulthood via 1.0 patch releases and then eventually into 2.0. Quality and revenue a...
