HPR1629: Banana Pi - First Impressions
The Banana Pi - First Impressions They say duplication is the sincerest form of flattery, substitute the word of your choice for 'duplication'. The Banana Pi is made in China and bears an uncanny resemblance to the Raspberry Pi. Not just the name, the board is fractionally larger, some of the features on the board are similarly placed: 26-pin GPIO 3.5mm analogue audio jack RCA composite video jack SD card slot There are things the RPI does not have: Power button uBoot button Microphone USB-otg port (otg = on-the-go, a bi-directional USB port) SATA connector The processor is a dual-core running slightly faster than the Raspberry Pi, although to be fair, of course, the RPI can be over-clocked. The Banana Pi has twice the RAM and a dual-core processor. The SoC is the ARM Allwinner A20. Getting my Hands on a Banana Pi My first Banana dropped through the letterbox a couple of days ago. Thanks to some kind soul on the Raspberry Pi Facebook group who described the connectors on the edges of the board I narrowly avoided plugging the power supply into the USB-otg port. The power micro-USB is on the underside of the board between the SATA power and data connectors which are on the upper side of the board. Can't really say much about it because I can't actually see the build quality, but it feels nice. The PCB is fractionally thinner than the RPI. Problems I had an initial struggle to find a download link for any images. The downloads page of has a two row table on it which appears to be upside-down and it has links to Google-drive, two different public DropBox links, a MS One-Drive link, and something I didn't initially find, an FTP link. Both of the DB links are duff because they have suspended the account because of excessive traffic. This is the FTP download link: Available Images When I found the FTP page I grabbed images for: Arch Linux Bananian-latest Lubuntu Raspbian I downloaded and extracted all of these images to my Debian desktop machine and tried to write and boot them in succession. The first I tried was Arch, on the assumption that would not have a desktop installed. After writing the card I looked at it on my Debian machine with parted and it appeared to have two partitions. As with the Raspberry Pi there is a small FAT16 partition and a bigger ext4 partition. The FAT partition contained the same files as the Raspberry Pi: config.txt cmdline.txt kernel.img And some others I can't remember. In addition it contained: uEnv.txt uImage It appears uEnv.txt is equivalent to the Raspberry Pi cmdline.txt file, and uImage is, of course, the kernel. So oddly it has the files for the RPI and it's own in the FAT partition. Then I tried Bananian, and this appears to be Debian Wheazy for ARM. Similar story with the FAT partition. It is a very minimal installation which has little more than the Linux Standard Base (LSB) packages. I like this because I like to have control. Sound and Stuff I found a review from April this year that said the sound driver snd-bcm2835 was not available. At the name snd-bcm2835 my heart sank because I expected the BPI to have the same stuttering text-to-speech problems as the RPI. Not expecting much I did, as root: apt-get install alsa-base alsa-utils Looking through /lib/modules/... blah blah I found a driver called: snd-aaci.ko I did: modprobe snd-aaci And then: speaker-test And I got pink noise! Next I did: apt-get install espeakup update-rc.d espeakup defaults modprobe speakup_soft And speakup burst into life with no stuttering! Immediate Conclusions The online community and code-base for the Banana Pi is not yet very mature, and because the origin of the beast is China, a lot of what's out there is in Chinese. But it is growing. And after all, it took the RPI a while to take off and go ballistic. At the moment I would say the Banana Pi is not for the faint-hearted or the total newbie, although, a lot of newbie questions are generic and don't have machine-specific answers. Links LeMaker page: Australian community page with forums: The worst thing about the Banana Pi is, when writing emails about it, and these show-notes, typing the word 'banana' and knowing when to stop!

HPR1627: 5150 Shades of Beer: 0001 He'Brew Hops Selection from Smaltz Brewing Company
Smaltz Brewing Company - He'Brew (The Chosen Beer) Hops Collection David's Slingshot - Pours golden, like an American lager, large head that subsides, rye aroma. Blend of multi-grain malts, an emphasis on hops w/o being excessively hoppy. Citrus taste from the hops. Malts: Specialist 2-row, Carmel Pils, Rye Ale, Crystal Rye, Vienna, Wheat, Flaked Oats Hops: Cascade, SAAZ, Summit, Citra, Crystal Genesis Dry, so dry you could be excused for wanting a glass of water to go with your beer. Bready, not biscuity, like a fresh sourdough loaf, almost makes you want to spread butter over your beer. Just enough hops to be interesting rather than annoying. Just a little sweet on the back end, so subtle you'll likely miss it on the first sip. Watery mouth feel. 5.5% ACL. Malts: Specialty 2-row, Munich, Core Munich 40, Wheat, Dark Crystal Hops: Warrior, Centennial, Cascade, Simcoe Bittersweet Lenny's R.I.P.A. Double Rye (an ode to comedian Lenny Bruce). Pours very dark amber, small head. Aroma of sweet rye bread. Sweet honey taste w/o being cloying, washed away by the hops. Strong rye flavor, much more than Slingshot. Malts: 2-row, Rye Ale Malt, Torrified Rye, Crystal Rye 75, Crystal Malt 80, Wheat, Kiln Amber, Core Munich 60 Hops: Warrior, Cascade, Simcoe, Saaz, Crystal, Chinook, Amarillo, Centennial Hop Manna IPA Pours medium amber with a good head. Little distinct aroma. For the hops enthusiast who doesn't want other flavors getting in the way, but still not so hoppy that the hops get in the way of the hops. Hoppy enough to satisfy most hops heads without making your tongue feel like it is under assault from the Hop High Command. Malt: Specialty 2-row, Wheat, Munich, Vienna, Core Munich 60 HOPS: Warior, Cascade, Citra, Amarillo, Crystal, Centennial Dry Hop: Centennial, Cascade, Citra Even though hoppy beers aren't my preference, Smaltz/He'Brew were 4 out of 4 winners. If you see this brand, grab it with both hands. Even if I hated the beer, I'd be a fan because each bottle lists the malts and hops, giving the home brewer a shot at replicating the brew and the expert consumer a hint of what the beer is going to taste like before purchasing.

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.

HPR1620: Passwords, Entropy, and Good Password Practices
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 Links:

HPR1619: Bare Metal Programming on the Raspberry Pi (Part 1)
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. CATRPI Homepage: Git repo: git:// My own repository of code that I wrote during this little project. Adafruit USB to TTL cable Script to build the ARM toolchain ARM ARM Contains the ARM assembly language as well as chip architecture overview. You'll need the ARM 11 Architecture Reference Manual ARM TRM Contains info about the specific SOC that the Raspberry PI uses RPI Schematics Shows how the Raspberry Pi is wired up RPI Peripherals Describes functionality and programming model for the various Raspberry Pi peripherals.

HPR1615: 39 - LibreOffice Calc - Inferential Statistics Functions
Inferential statistics is what you do to say that something is likely, or that it is not due to chance, or things of the sort. It goes beyond simply describing what is in the numbers and lets you say something about what the numbers in a sample might mean for the population that generated the sample. There are several type of Inferential Statistics that I want to address in this tutorial, beginning with the idea of a confidence interval. - For more go to
