Review: PennMobile app, and its botched launch

In the past, I’ve written about scams in computer services, and poor use of technology on a campus media site. Now bringing you… my views on a student government project to deliver a mobile app, PennMobile, to the University of Pennsylvania.

Since I was involved with planning when the 2013-2014 Vice-President of the UA was drafting the Penn Mobile App Resolution (which passed on December 8, 2013), I have been tracking the project and offering feedback since its inception. On multiple occasions, I have been disappointed with how the project was realized.

In this 3-part post, I’m going to cover:

  1. The botched initial public release
  2. Still unfixed bugs on Android that were reported
  3. The original vision

Installing a Puppet master on CentOS 7 with nginx and Unicorn

I was experimenting with configuration management tools, and wanted to set up a Puppet master node for my virtualized machines.

It is unfortunate that most guides out there today are tailored specifically for Ubuntu, or rely on prepackaged DEBs that do all the work (which, obviously, don’t really help on CentOS/Fedora/RedHat). This guide on DigitalOcean for setting up a Puppet master on Ubuntu 14.04 is pretty solid, but my own preferences are for CentOS and Fedora. Furthermore, I have completely migrated to using nginx in all my servers, though many deployment guides for Puppet still use Apache and Passenger. And the closest I could find in a guide for CentOS 6, nginx, and Unicorn used SysVinit and God… which are unnecessary now that systemd has been adopted.

(If you’re not as picky, just use Foreman Installer. It’ll take care of everything… even on CentOS 7.)

This guide will use:

  • CentOS 7 (at the time of writing, latest release)
    • systemd
  • nginx 1.7.x (mainline, from official nginx repository)
  • Unicorn
  • Puppet open source 3.7.x

Fedora 21 on XenServer

In this post:

  1. Prebuilt Fedora Cloud images for XenServer
  2. Kickstart scripts for Fedora Server on XenServer

Fedora
Fedora 21 was just released earlier this week on December 9, 2014. The biggest change was the separation of the distribution into three “products”:

  • Fedora Cloud, a lightweight optimized distribution for public/private clouds, containerization with Docker and Project Atomic.
  • Fedora Server, the traditional platform for running services, usually on a headless host whether virtualized or on baremetal.
  • Fedora Workstation, a developer-friendly desktop running a cutting edge OS.

Of course, as always, OpenStack/KVM and Docker get a lot of love, but Xen and XenServer are once again ignored. This post is my solution. With the prebuilt images distributed here and the kickstart scripts below, you can deploy Fedora 21 on your own XenServer (6.2+).

The silent threat

On September 11, 2001, some 3000 Americans were killed by terrorists... every year since... some 20000 Americans died because they couldn't get health care.

Terrorism is salient and graphic. Wars abroad are visible — at least imaginable. Justifying trillions in spending on fighting threats that can be exaggerated is easy when triggering fear in the population is as easy as reporting a claim without evidence; even more so when all Americans feel like it’s a threat they face.

But death from lack of access to medicine isn’t the kind of problem that privileged lawmakers and the people with power and influence tend to encounter, except, perhaps, the doctors and health economists who see it most vividly.

Found some old screenshots…

When I first came to Penn, the website for the Nominations & Elections Committee looked like this:

Old NEC site circa 2011
No, this wasn’t the year 1999… this was in 2011.

NEC website redesign

I set out to redevelop and redesign this, upgrading it from a static HTML site edited over SFTP to a WordPress CMS on Canvas. More importantly, the website redesign in 2012 needed to fit the rebranding that Penn underwent that academic year. In other words, I wanted it to look more like the university’s design. (An email to the Communications office responsible for web assets clarified that we could, in fact, do this.)
