New glossary

[PhatFil]

Great idea ..

[davidcoton]

Just because GNU has a history to 'deserve it' it doesn't mean anyone needs to know or will use the term and want to look it up.
It's just adds clutter.

It would be more useful to have PinkPonies and what it means than GNU.

[humour]
I'm a GNU.
Or am I a Pink Pony, or even a Unicorn?

Help, I'm confused, I need a Glossary ...
[/humour]

Pink Pony: Feature request for a future model of Pi that is unlikely to happen.
Unicorn: See Pink Pony.

[W. H. Heydt]

"Bluetooth" - Used to connect from your phone to the Pi or to connect the Pi to sensors.

That should require a mention of Harald Bluetooth, for whom the protocol is named. He was a late 10th century Danish king.

"Polyfuse" - A self-resetting electronic fuse fitted to the Pi board which can help protect your Pi from electrical damage.

Electrical fuse, not electronic.

BCM2835 Add the A+ to the list of Pis that use it.

Need disambiguation for ISP as it is also Internet Service Provider.

Since A (Ampere) and V (Volt) are in the glossary, you may want to add W (Watt == power). I don't *think* you need to add Wh (Watt-hour == energy).

[rpdom]

I don't *think* you need to add Wh (Watt-hour == energy).

Perhaps "mAh, Ah and Wh are units of power capacity commonly used in rechargeable batteries/powerbanks, not to be confused with mA, A or W"

[jamesh]

OK, added the ones I liked from the lists above.

It no way is intended to close a thread, it is just easier than writing a diatribe in response to an absurd post !

Unfortunately it often is used that way and you seem to forget the one rule this forum has; "be nice to each other". If you don't have anything good to say it is perhaps better to not say anything at all or have the decency to explain why - in your opinion - something is absurd, claptrap, drivel, hogwash, poppycock and balderdash

As it is it's little better than shouting names at posters. As you seem to be admitting, it's your substitute for diatribe; "a forceful and bitter verbal attack against someone or something".

I don't *think* you need to add Wh (Watt-hour == energy).

Perhaps "mAh, Ah and Wh are units of power capacity commonly used in rechargeable batteries/powerbanks, not to be confused with mA, A or W"

Yeah...except mAh and Ah *aren't* units of energy, which Wh is. The problem with so many batteries being given mAh/Ah ratings is that far to many people don't realize that the implied voltage for the rating is 3.7v, rather than the 5v output. That's why I usually tell people to convert everything to W and Wh's to see the true capacity and load. Fortunately, all of this is DC so RMS and phase angles don't enter the picture.

Perhaps a mention of "dimensional analysis", aka Keep Your Units Consistent.

mAh is a human readable form of coulomb, a unit of charge.
though I see you're getting at Wh (which isn't a unit of charge), now I read again

hi jamesh and contributors,

Excellent work!

One minor cosmetic issue, between the "term" and the "description" sometimes a hyphen is used, sometimes a long dash.

Since everything Pi is either 3.3v or 5v--and when you're sealing with anything more that a few mA, it's 5v--the problem area that comes up time and time again is basically an advertising problem. Companies tout LiPo battery capacities in mAh (or--occasionally--Ah). Since that is based on a 3.7v cell voltage, it makes nice impressive numbers. The problem comes when people try to treat that as being at 5v, as that's the converted and regulated output. So...people overestimate battery storage capacity and then get all flustered and confused when those who do know what is going on point out that the battery capacity is a lot less than they think it is.

It's far better to use Watts and Watt-hours to calculate how long a given battery will last.

If you include "root" then you need to describe the user "root" and the origin of the file system? Hmmm.... do you then need to describe a file system...

[mahjongg]

If the BCM28xx family is in the glossary (with description of differences between them) I would also describe the LANxxxx chip family and the various variations the PI family uses, 2-port 4-port and 10/100 and 10/100/1000 versions.

another one is the A/V (= audio/video) connector.

and what about:

PAL = Phase Alternating Line
and
NTSC = Never the same color (just kidding, it means National Television System Committee)

[W. H. Heydt]

NTSC = Never the same color (just kidding, it means National Television System Committee)

The version of that I heard....entirely too many years ago...was "Never Twice the Same Color".

Me too.

If anyone wishes to add things to the glossary, it's easy enough to send in a PR. Then I can assess it, get it copy edited and merged. I'm a bit lacking in time to add stuff myself at the moment.

[mahjongg]

Perhaps we can put "PR" in the glossary, because I have no idea what you mean....

Sorry, meant to add this link to the post.
