hpr2258 :: Killer Keilbasa

Quick recipe for that last minute party

I have heard out here a few recipes so I figured I would throw one out here that goes over real well when we make it.

Recipe:

  • 1 Lb. Keilbasa (your choice)
  • 2 TBSP Ketchup
  • 2 TBSP Brown Sugar
  • 2 Table spoons jelly (I have used orange Marmalade, Grape Jelly and various flavors of Jalapeno or pepper jelly)
  • Crock Pot (Slow cooker) or sauce pan
  • In crock pot add Kielbasa sliced in 1/2" pieces
  • Add jelly
  • Add Brown Sugar
  • Add Ketchup

Turn crock pot on medium for 2 hours checking and stirring every half hour. Should be ready in 2 hours.

In sauce pan on medium heat stirring continuously until mixture liquefies and the Kielbasa look done. Probably less than 20 minutes this way but you have to watch it or it burns. This is why we use a slow cooker.

I make 5-7 lbs at a time for a party and usually it is all gone by the end of the party. So I take it that it is a hit. This also is pretty good over rice. Almost Asian style.


hpr2257 :: Watt OS

a short show about the Linux distro Watt OS

Hosted by Tony Hughes AKA TonyH1212 on 2017-03-28 is flagged as Explicit and released under a CC-BY-SA license.
Listen in ogg, spx, or mp3 format. Series: Hardware upgrades | Comments (0)

In this short episode I tell you about installing Watt OS onto an Acer Aspire One Netbook from 2008.

This net book came with a 8Gig SSD installed and a 32bit 1.6G atom processor and many modern Linux spins are just too big for the hardware.

However Watt OS came to the rescue and installed on the Netbook without issue.

I plan to give it a go on a Lenovo x61 shortly and will let you know how that works out, my thought is it will fly on that hardware.

hpr2256 :: Modular Game Scaling

how I allowed more display resolutions in a modular game design


Hosted by Eric Duhamel on 2017-03-27 is flagged as Clean and released under a CC-BY-SA license.
Listen in ogg, spx, or mp3 format. Comments (0)

NOTE: the audio didn't cut together as smoothly as I remember from the first time, probably because I forgot to record at 44.1 KHz

In this episode I explain in broad terms how I programmed a game system to adjust its display resolution using three distinct modules operating individually and in concert.

  • The "metagame" (launcher) module accepts an argument describing the size of the window available for display
  • The "gameplay" module is informed of the space available as a 'window' into the game world and uses it for one thing or another
  • The "graphics" module opens a window at the specified size and modifies the graphical assets if needed

Once again I recorded in parts using a program called Urecord on my pocket computer (mobile phone).

I program using Pygame, post on a GNU Social account, maintain a personal website at NoxBanners.NET, and study programming techniques at Refactoring.com, style at Python.org, and sometimes patterns at Portland Pattern Repository


hpr2255 :: The Good Ship HPR

HPR is a wonderful yet fragile project completely dependent on a steady flow of shows from hosts

The Good Ship HPR

Hacker Public Radio

What is it?

The podcast called Hacker Public Radio (HPR) is an amazing phenomenon. It has been providing an episode a day every weekday for years, and these episodes originate from the community.

I heard someone refer to HPR as “Crowd Sourced” which seemed like a good way of describing things. It is an open access resource which is managed under various Creative Commons licences, usually CC-BY-SA.

The content is very broad in scope. Anything “of interest to Hackers” is acceptable, which is interpreted in a wide variety of ways.

Access to shows is open to all through the HPR site, where shows back to episode 1 can be browsed, notes read, etc. There are feeds which propagate various updates: to shows, series, comments and email. Current shows are archived to the Internet Archive (archive.org) within a few days of appearing in the main feed, and older shows are gradually being archived this way with the intention of eventually storing everything there.

For example, to find show 1999 on archive.org look for https://archive.org/details/hpr1999. The entire HPR collection can be browsed at https://archive.org/details/hackerpublicradio.

Some history

As you can see, if you examine the details on the website statistics page the predecessor of HPR started more than 11 years ago as “Today With A Techie”, transforming into “Hacker Public Radio” over 9 years ago.

Started:            11 years, 4 months, 12 days ago (2005-10-10)
Renamed HPR:        9 years, 1 months, 20 days ago (2007-12-31)

In the earlier days the frequency of show release was not the predictable 5 per week, every weekday, that it is now. There were gaps, sometimes of several days, and occasionally shows came out on the weekend. Stability was achieved in October 2012 and there have been no gaps since then!

There are currently 280 hosts who have contributed shows at some point in the history of HPR, and at the time of writing in February 2017 show number 2230 has been released. The number of episodes and hosts will be greater when the episodes from “Today With A Techie” are incorporated into the archive.

The Hacker Public Radio experiment has been very successful over the years, but there is a certain fragility in the way it works.

Long notes

The longer notes for this episode which are available here, talk about the details of the problem facing HPR and go on to suggest some solutions.

  2. A little about my personal interests in model rocketry.

Resources

The following is a non-exhaustive list of companies that manufacture and/or sell model rocket kits and suplies. I've primary listed those that I'm most familiar with. There are certainly others.

These are some of the major manufactures of high power composite motors.

These are the two United States national model rocketry associations.

Resource for competition rocketry.

Here are a number of other interesting links

Errata

In the show I said that G. Harry Stine worked at the White Sands Missile Base. The correct name for that facility is White Sands Missile Range. But, during the time that Stine worked there, it would have been called the White Sands Proving Ground. http://www.wsmr.army.mil/
