In this show I interview Ben Everard, former editor of Linux Format who is now promoting a crowd-funded campaign through Indiegogo
for a new Linux magazine, Linux Voice. We also talk about Ben's other project which is a book called "Learning Python with Raspberry Pi" from Wiley Publishing. Later in the podcast we talk about how Ben arrived to Linux and what he finds to be the most exciting thing he has written about as well as what's going on in the Linux world.
I can't take the credit for all this detailed information in my podcast, I found this fantastic website many years ago while investigating why the battery in my expensive razor prematurely failed. I tried to hunt for the site but couldnt find it. I wrote up all my notes from memory and recorded the show. It wasn't until I started working on part 2 of my batteries show the I stumbled across this long forgotten site at least I think it's the same one as it talks about the memory effect on satellites and doctors pagers so I guess it must be the same one. I'm indeed delighted to find it still exists, and I may very well read it again from top to bottom. It looks like it's been updated a little too. well done ka7oei a fantastic resource right enough.
The charger I use is made by the same company as this although mine is a different model. My model charges at 200ma, and takes about 13 Hrs to charge a 2100 mAh battery. I can't tell what charge current this charger deliveries, but suspect it's a simple slow charger, probably old stock, as I said slow chargers are getting like hens teeth.
Keith Murray talks about the things you need to consider when setting up your own blog. Topics discussed include hosting options, software platforms and a brief discussion of some of the underlying technologies involved.
Links to many of the topics and projects discussed are included below.
Metadata in MP3, Opus/Ogg/FLAC/Speex, and other audio files.
Today's episode discusses (and encourages) the use of metadata tags in audio files.
Most of the episode is spent on id3v2.3 (metadata for mp3 files) and vorbiscomments (metadata for opus, ogg vorbis, flac, and speex files), and how to mix them, though metadata in webm/matroska, windows media, and wav files is briefly discussed as well.
This episode's files have also been crafted with substantially more metadata than the ID3v1 set of tags that HPR normally limits itself to, to serve as examples.
Listeners to the opus, ogg (vorbis), or speex versions will also have access to chapter markings if your playback software recognizes standard vorbiscomment chapter metadata. (No chapter markings in the mp3, as support for it is extremely sparse, and I've not
yet even managed to find a tool for making mp3 chapters that actually works - the java utility I mention in the episode crashes on me without starting...)
All metadata conforms to the published standards, so your playback software should at best fully use it all, or at worst simply ignore it. If your player software actually DOES have a real problem with this file, I would very much like to know!
If there's anything wrong with the metadata, blame Epicanis, not HPR (I did the metadata myself).
If you hear or see any errors in this episode, please tell me. I'll issue appropriate corrections in subsequent episodes. If I'm a big enough screwup with this episode, I could even do a small episode on "everything I got wrong in my metadata episode" if I did
badly enough. I don't THINK there should be more than a few minor errors or omissions here, though.
ERRATA: In chapter 18 (at 34:53) there is one small error: oggenc does NOT transfer attached pictures from flac input (though it DOES transfer all vorbiscomment metadata. FLAC stores attached pictures in a separate metadata structure so oggenc misses it.
opusenc - at least in recent beta versions - DOES appear to transfer the attached pictures as well as the vorbiscomments, though. Another reason to upgrade to opus, I suppose...)
This is a personal view of the Universe, as viewed
from the Earth in the early 21st Century, by a somewhat
geeky chap. In this episode, I talk a little about my first memories
of looking at the night sky and how the modern science of astronomy
has its roots in ancient mythology, and how the sky provided
a picture book for humanity before we even did our first cave painting.
This program is about the new online streaming music service from Google, called Goolge Play Music All Access.
Like many people I enjoy listening to music, and having my music with me everywhere is important. And I have a large music collection to draw on. Trying to have everything with me at all times is a bit of a problem, though, considering how much music I have. Right now I own a number of portable MP3 players, two of which are full of music that I carry with me. My pockets can get very full that way, though, and while I like listening to tracks I own, what about finding new stuff? My MP3 players have never suggested anything to me. This is where the cloud services come in.
In this episode of our Privacy and Security series we look at the fundamentals of encryption and how it has developed over the centuries. We will also develop a basic idea of the current asymmetric public key cryptography.
