hpr2342 :: Wherein our hero fails to repair a garage door.

Released on 2017-07-25 under a CC-BY-SA license.

My garage door failed spectacularly for a second time. I make an attempt to repair it but find that my extension cables are a bit too short. I hope I can explain a little about how garage doors work along the way.


hpr2216 :: Working AO-85 with my son

Released on 2017-01-30 under a CC-BY-SA license.

Working AO-85 with my son!

Given all the talk about Amateur Radio on the mailing list, I decided to record a live operation show. In this episode my son and I try to make a contact on AO-85. He eventually loses interest and it's just me yelling into a microphone.

We don't manage to make a successful contact but we do pick up the bird. One person toward the end tried to pull us out of the noise but there were simply too many people utilizing the satellite for us to make contact. Part of that may have been my Doppler shift settings.

Here is the pass data from gPredict (in CST) for this particular attempt:

hpr2077 :: libernil.net and self hosting for friends and family

Released on 2016-07-19 under a CC-BY-SA license.

What is libernil.net?

libernil.net is an island of pseudo-freedom. This project was established in order to pursue ideals of Free Software, Free Culture, ethically sourced hardware, self hosting, and sharing with others. Generally it consists of personal content, though some community resources reside here as well.

The name came from an old programming group and was repurposed. I would really like to find a new name!

Similar networks

  • sdf.org

The network

Set in three physical locations: two in Northwest Arkansas, one (a VPS) in Sweden.

One recycled shuttle rig called “summernight”, one ThinkPenguin nano called “aprilshowers”, and a VPS known as “eremit”. Two or three inaccessible machines for backups and other automation.

Wireless access provided in the openwireless.org model at both US physical locations.

Events and community

The community is very loosely organized and rarely operates under the name of the network, though we sometimes gather for events in the same location as the machines. In the past we’ve had a cryptoparty and I am trying to organize a FreeDOOM LAN party.

How to host your own services

  1. Acquire a machine, any machine! Could be a junk rig, an old laptop, or a fancy single board computer.
  2. Install your favorite distro or try freedombone/freedom box.
  3. Get a domain name with your favorite registrar.
  4. Get a static IP from your ISP if possible or go with Dynamic DNS
  5. Install Bind or set up your router to manage DNS.
  6. Invite some friends to play on your new server! Maybe have a party!
  7. Set up backup scripts.

hpr2026 :: What's in my Bag... Again!

Released on 2016-05-09 under a CC-BY-SA license.

Just a look at what I keep in my bag these days, though I forgot to mention my beloved Zojirushi thermos (SM-JA48-BA)!


hpr1558 :: Lunch Breaks

Released on 2014-07-23 under a CC-BY-SA license.

Back after a year of HPR silence, I'll talk a little about how I like to spend my lunch breaks and how you can explore your workplace. Put down those tater tots, we're going on an adventure!

In this episode I'll give some information about my lunch history, ways you can maximise your time, gear you'll need to start short stealth/urban exploration, techniques for finding places to explore, and ways to handle being spotted.

If this goes well enough and the audio isn't too garbled, I'll record episodes for the "How I Got Into (GNU) Linux" series.

Here are a few links related to the episode. Note that I link to Amazon and Google. I don't necessarily condone or endorse either service, I just didn't know of any better sources for product information.
