A Less style-sheet for Pygments using the Solarized color-scheme

Information on Solarized is at http://ethanschoonover.com/solarized

Two mixins, .solarized-dark and .solarized-light are provided for convenience
and if you wish to use your own primary and secondary colors, you may call the
.solarized mixin and provide parameters for the primary and secondary values.

The CSS class names are derived from the CSS classes that Pygments uses when

In the Eclipse External Tool Configuration window, I set Flake8 up as follows:

• Location: /usr/bin/flake8
• Working Directory: empty
• Arguments: --format="%(code)s %(text)s [%(path)s:%(row)d:%(col)d]" ${project_loc}

With this Flake8 format, the information about the error is printed first and the location second.

I could not figure out a way to get Eclipse to print a proper relative directory (Even using ${resource_path} printed a leading slash). Nor could I figure out how to get GrepConsole's base directory setting to read from an Eclipse variable. The result with the default Flake 8 format was that in order for everything to work, I had to use absolute path names which crowded all the useful information out of the immediately visible portion of the console. With the custom format, the interesting stuff comes first and the dross is at the end.

# In Fedora 20, Tomcat 7 has an annoying habit of creating log files that are named
# "catalina.YYYY-MM-DD.out" with the day's date filled in the file name.  It is a pain in
# the neck to have to remember the date every time I want to look at the log file and
# tab completion doesn't help because it will only complete as far as the most common
# string which in the case of the date is usually the year.

# StackOverflow to the rescue: http://stackoverflow.com/questions/4511845
# My solution was slightly different though.  I set "rotatable" to false, but instead of 
# adding a "suffix" option in /etc/tomcat/logging.properties, I just changed the "prefix" option to
# remove the period.

IntelliJ has support for working with Podman but there are some hoops you need to jump through first. The first obstacle is getting the podman API up and running continually. Normally the API is only up while needed and then shuts down. You can change this by creating a local systemd unit file that starts the API server for you when you log in. Here's the unit file:

[Unit]
Description=Podman API Service for IntelliJ
Documentation=man:podman-system-service(1)
StartLimitIntervalSec=0

[Service]
Type=exec

What I Know About PKI

Abstract Syntax Notation One (ASN.1)

Much of the data in the PKI world is stored in ASN.1 so a basic understanding is necessary. ASN.1 is a way to describe data by starting from primitive types and building up to more complex types. Do you remember Backus-Naur Form? What about writing XML schemas in XSD? It's the same concept.

Let's say we have a Widget. Every Widget has a model name, a serial number, and some inspection information with the name of the inspector and the dates of the inspections. Our Widget then looks like this in ASN.1:

Widget ::= SEQUENCE {
    model IA5String, 

serialNumber INTEGER,
