LLC-Technologies-Collier/Demo-SCCC-Byte-AngularJS

Posted on December 6, 2015 by C.J. Collier

Hello dear readers and attendees,

This is the post that I will be/ will have been referencing during my presentation to the Seattle Central Community College’s Byte club on Thursday, December 10th at 1500-1630.

I will begin with a bit of an autobio and find out what kind of students we have in attendance. Please feel free to comment if you’d like to keep in touch before or after the presentation. I will discuss some of the bits and pieces of some industry standard platforms which I’ve developed, deployed, maintained, managed, co-operated, administered and replaced. We can discuss some of the patterns that work well in the industry, and some that are a bit harder to tame.

Once we have touched most of the areas of specialization represented at the meeting, I will dive in to an AngularJS demo I am developing in github here:

https://github.com/LLC-Technologies-Collier/Demo-SCCC-Byte-AngularJS/tree/master

To follow along with the presentation, please run these commands or something similar. My development environment is Debian stable. So yes, this means that we’re not doing a demo of the state of the art. But it also means that the infrastructure has been exercised under load and in production.

Install Debian package dependencies

First, install the debian packages of nodejs and npm, the node package manager:

cjac@debian0:~$ sudo apt-get install nodejs nodejs-dev nodejs-legacy npm

Check out the git repository

After this, check out the repository from github and create a branch for your work:

cjac@debian0:~$ mkdir -p /usr/src/git/github/LLC-Technologies-Collier
cjac@debian0:~$ cd /usr/src/git/github/LLC-Technologies-Collier
cjac@debian0:/usr/src/git/github/LLC-Technologies-Collier$ git clone git@github.com:LLC-Technologies-Collier/Demo-SCCC-Byte-AngularJS.git
...
cjac@debian0:/usr/src/git/github/LLC-Technologies-Collier$ cd Demo-SCCC-Byte-AngularJS
cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ git checkout -b $USER

Upgrade to latest npm, install deps

Once we have the git repository checked out, we’ll grab the latest version of npm and the rest of the node modules

cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ export PATH="$PWD/node_modules/.bin:$PATH"
cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ npm install --save-exact npm@"2.1.0"
cjac@debian0:.../Demo-SCCC-Byte-AngularJS$ npm install --save-exact `cat pkgackage-list.txt`

This post and the associated git repository will be updated between now and the presentation on Thursday. Please chime in and feel free to get involved!

Regarding fdupes

Posted on November 23, 2015 by C.J. Collier

Dear readers,

There is a very useful tool for finding and merging shared permanent storage, and its name is fdupes. There was a terrible occurrence in the software after version 1.51, however. They removed the -L argument because too many people were complaining about lost data. It sounds like user error to me, and so I continue to use this one. I have to build from source, since the newer versions do not have the -L option.

https://github.com/tobiasschulz/fdupes

And so there you are. I recommend using it, even though this most useful feature has been deprecated and removed from the software. Perhaps there should be a fdupes-danger package in Debian?

I think I just accidentally the whole Seattle EDM scene

Posted on October 27, 2015 by C.J. Collier

It was unintentional, I promise.

PS, what are you doing the night before Samhain this year? Feel like giving me and my bike a ride to Bellingham?

Some statistics from the router at the cabin

Posted on October 26, 2015 by C.J. Collier

sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don’t get centurylink easter eggs in my search results when I use this interface.

eth9 is the local gigabit transceiver. Attached directly to a SIP phone which bridges to a gigabit switch, on which the Ubiquity equipment participates.

lo is the local loopback interface, of course. Good old 127/8

usb1 is the 100Mbit USB NIC to which the WRT54G with ssid ‘colliertech.org’ is attached. The vast majority of the traffic originates on this interface.

Microsoft ACS announcement

Posted on September 18, 2015 by C.J. Collier

So it seems that Microsoft has developed an embedded device OS distribution called ACS and that this OS is based on the Linux kernel.

http://azure.microsoft.com/en-us/blog/tag/azure-cloud-switch/

That’s kind of neat.Â They’ve been consuming Linux for quite some time.Â It’s nice to see that they’re producing some, too.Â Thank you for being productive members of this community, Microsoft!

Back on the island.

Posted on September 9, 2015 by C.J. Collier

I spent a couple of weeks straight in the city. This is the first time I’ve done this since I’ve started working with Scott and the crew at RP. It was an overwhelming period of my life. Lots of social dynamics were fluid in a way that they have not been before. I had recently had my bicycle stolen and my 36th birthday. I invited people who I love to our space on Orcas and think that they were only there out of a sense of social obligation. I spent a good deal of time thinking about my influence and impact on the world. I spent time contemplating how I’ve never lived on my own and have never been ultimately responsible for my own well being. I have always relied on others to provide the comfort that would be best coming from myself. Self received a lot of coverage in this phase of my life. Perahps to the point that I might also consider myself to maybe be the most self-centered person I know. Maybe now that Leo has left us in its wake, we should get on with the regularly scheduled program.

And so. Planning. I’m looking to get a studio where I can work on island. I’m planning on moving the rack to this studio and maybe keeping it in a sound dampening, HVAC-enabled section of the space. A workstation with a dock ready for my presence or return. That sort of thing. Maybe I should put up a sign that says professional services, and another sign that says “no vacancy” so that they know that I’m already working for someone else. :-)
