This is meant to be a short tips and tricks for working with a PBC. I'm assuming you have already followed the directions for lighting your PBC and are trying to troubleshoot some issues with temperatures. They don't discuss monitoring temperatures in their videos but it's something I started doing with my Weber kettle and I've continued that with my PBC. I'm glad I did because some of my early cook saw temperatures in my PBC spike to nearly 500 and temperatures settling in the upper 300s. I'd read about it running down in the 275-325 range and wanted to get mine to cool off a bit. I use Kingsford Professional which is not something they recommend but I prefer to use 100% natural charcoal and no lighter fluid as I spread the spent ashes on my yard to help my yard and reduce the amount of trash I create. If you really want to learn a LOT about cooking with a PBC, join The Pit over at Amazing Ribs and checkout the dedicated PBC forum . There is also a lot of g...

If you try to install psycopg2 on a Greenplum system using pip you may run into this error: ... Error: pg_config executable not found.       Please add the directory containing pg_config to the PATH     or specify the full executable path with the option:         python setup.py build_ext --pg-config /path/to/pg_config build ...     or with the pg_config option in 'setup.cfg'. ... The solution is to add the path to the Greenplum bin directory to your environment PATH. export PATH=$PATH:/path/to/greenplum-db/bin/ Then run pip install psycopg2 and all should be good.

The lag in my Google Fiber remote was driving me crazy. Figured out how to disable bluetooth & go back to IR only on the remote. Lag problem solved.

I wanted to double check what a script looked like two commits ago. git log path/to/file Get the commit number from the version I want to see, get the first 4 to 6 characters. git show commit#:path/to/file Credit goes here

I wanted a list of pids only so I could run them through a while loop for processing. To get just a list of pids on Linux I used: ps --no-headers -o pid -C processname

SOURCE Get filename without path basefilename=$(basename /full/path/to/file.txt) Get filename without extension filewoext="${basefilename%.*}" Get extension of file fileext="${basefilename##*.}"

Not sure why I found this so challenging, maybe because I haven't done a netinstall in ages. Anyway, finally figured out how to setup the Installation Source your selected mirror/path/to/installation/end with os/ So for me it was: http://fedora.mirrors.tds.net/fedora/releases/23/Server/x86_64/os/ Key was to end it with os/.

I've been looking for a way to move a directory in a git repository to a new repository and preserve the history. We are reorganizing some code at work so that's what prompted me to start looking. The scenario is I have a repository and structure that looks like the following: repoA/  file1  file2  file3  directory1/   file1a   file1b   file1c  directory2/   file2a   file2b I want to move directory1 and all of the files in that directory(file1a, file1b, file1c) to a new git repository and preserve the change history. I want to end up with the following: repoB/  directory1/   file1a   file1b   file1c The  solution is here . I started with  this solution  but with the second solution I ended up with the files from my directory1 in the root of the repo. By the time I moved the files into a new directory1 the change history was stored in the root directory of the new repo so if I was i...

Using ls you receive the error that there are too many arguments: Example: find /path/to/files/ -name "*.ZIP" -exec basename {} \;

To copy the directory structure only without copying any files: rsync -a -f"+ */" -f"- *" source destination/ If you don't put the trailing / on source you'll get the source directory created in destination. If you put the trailing / after source, you'll get all of the subdirectories of source created in destination without the top source directory. Source
