Instructor for Python+Java+Arduino
School's Out Hackathon (SoHacks)
- 5 years 3 months
Education
Students from around Texas join together for 36 hours to create awesome projects. We create the largest maker-space for students to tinker and hone their skills in coding. I helped high school kids with laptops, arduinos, sdks, IDE's and with coding advice for beginners and skilled students alike.
Projects
-
Send apache server-status stubs to graphite.
See projectSends as many metrics about the apache server-status stub page as possible.
Including:
* Activeworkers
* Idle Workers
* Worker States
* BytesPerSec
* Etc. -
Test V API
See projectThis project revolutionizes API metrics and availability collection using BDD style language files to write test conditions for your API in english-style syntax.
Then the service can be triggered by ops automation or manually by QE for unit testing on your API.
The ops mode has a greylog mode which will allow all messages to appear in a greylog logstream.
I wrote it for reuse later in my career and plan to maintain it. -
Jenkens/Bamboo/<Insert Buildsystem> Physical Status Light Project
See projectUseful for implementing some physical status lights for failed builds, or some sort of operational status light like hosts going offline. Just need $50 for the device. Yippie.

Modula - The Flask Blueprint Skeleton
See projectNobody else did anything like this, so I decided to write one. I wanted a Flask skeleton framework that uses blueprint which could modularly load routes/controllers.
The routes/control is stored under blueprints, and the application only loads those modules if the extensions end in .py.
As a bonus, I've included Rackspace Cloud authentication modules and a bundled requests library to bootstrap getting things built for the Cloud. -
Rackspace Cloudfiles Backup Support with EC2 module.
See projectForked an Amazon EC2 python library and made a mostly cross compatible library. Need to get an Amazon EC2 account to cross-test the class methods.

See projectI built the spec and RPM's and uploading of the r10k management tool for both Centos 6 and 7.
I have also written a r10k wrapper that is part of the repository.

Tavve
Raw telemetry can overwhelm more than it informs. That’s why organizations are leaning on PacketRanger to make SNMP and NetFlow practical, cost-effective, and compatible with modern monitoring tools. Three ways PacketRanger helps: 🔹 Filter Before You Forward – Keep dashboards meaningful and reduce data costs. 🔹 Translate for Compatibility – Convert SNMP traps into syslog for SIEMs and aggregators. 🔹 Spot Anomalies at the Source – Catch misconfigurations and outages in real time. When SNMP and NetFlow are implemented intentionally, they become powerful tools for clarity and control.
