We started producing shows as Today with a Techie 9 years, 0 months, 17 days ago. Our shows are produced by listeners like you and can be on any topic that "are of interest to hackers". If you listen to HPR then please consider contributing one show a year. If you record your show now it could be released in 12 days.
We spent a lot of time looking at some Financial and Statistical functions. I don't propose to go into the remaining types of function in nearly the same depth. That would draw out the series without benefit to most people. But I do want to highlight some of the functions in the other categories so that you have an idea of what is possible in Calc. Remember that if you need to know more about them Google is your friend. - For more go to http://www.ahuka.com/?page_id=875
I am the coordinator for the Tech Track at Penguicon 2015, which is a combined FOSS/Science Fiction convention held every spring in the Metro-Detroit area. The 2015 event will happen April 24-26 at the Westin Hotel in Southfield, MI. The theme for the upcoming year's event is Biotechnology and medicine, looking at how technology is affecting our health and life. But we want a lot of different talks as well, so I will be happy to accept proposals that look at things like cloud computing, security, hardware hacks, and anything else that would be of interest to geeks and hackers.
In this episode of interviews from OggCamp 2014 I talk to George Doscher who co-founded (or founded, I really don't know) the Tech and Coffee Google Plus hangout. You'll find him at
and on Tech and Coffee under
In the second interview I talk to Keith Milner who has some interesting and fairly technical stuff to tell you about mobile networks. He also talks about unencrypted traffic on the carrier networks and why it's even more important for you to use encryption when using the web on your mobile. You find him under

The interview was conducted at OggCamp 14, a free culture unconference, held in Oxford UK on the weekend of October 4th-5th 2014.
Right now for most of us the key to any security in our online life is the degree of entropy in our passwords. So what is entropy, and how does it affect our passwords?
Entropy is in general the degree of randomness or disorder in any given system. Sometimes it is very easy to assess, such as a password of 1234, which all too many people use. Because it is a simple sequence, there is no real randomness at all, and would be quickly guessed. And as we saw in the last tutorial, such passwords are quickly discovered in a dictionary attack. There are things you can do to make it less likely that your password will be cracked and used against you. - For more go to http://www.zwilnik.com/?page_id=530
This show is about programming on a Raspberry Pi with on operating system or libraries. In this programming environment, the only software that the CPU executes is the software that you write. This episode introduces how to configure the build environment and get a basic application up and running. From here one can leverage these techniques to build more sophisticated applications and deepen ones knowledge of systems programming.
Here is some of the source material that I used while working on this little learning experience.
dwelch67's bare metal repository
- The best guide I know on this topic. Very thorough and what I used as my starting point.
- Homepage: https://gitorious.org/catrpi
- Git repo: git://gitorious.org/catrpi/catrpi.git
- My own repository of code that I wrote during this little project.
Adafruit USB to TTL cable
Script to build the ARM toolchain
- Contains the ARM assembly language as well as chip architecture overview.
- You'll need the ARM 11 Architecture Reference Manual
- Contains info about the specific SOC that the Raspberry PI uses
- Shows how the Raspberry Pi is wired up
- Describes functionality and programming model for the various Raspberry Pi peripherals.
This show includes two interviews with OggCamp attendees this year.
The first interview is with TDTRS co-host Peter Cannon, who is convinced that his podcast is the best Linux podcast there is and he is sure going to tell you why.
In the second interview I talked to Alistair (whose name I hopefully spell correctly), who told me that he would like to be a HPR host himself. So this ist his first appearance on HPR and hopefully not the last.
If this show only confuses you, search the Internet for the Android app Spaceteam, have some friends install it and start playing. To maximize the fun you preferably play in a public place.
