SD card programing -
by Bob Goodwin
I just received a Raspberry Pi 2b as a birthday gift. Apparently the
operating system must be stored on an micro-SD card, the o/s can be
downloaded but I have to get the SD card and whatever is required to
program it from Fedora 21 or 22, or buy one preprogrammed.
Perhaps someone with experience there can enlighten as to what I need to
order to do this?
Thanks,
Bob

Fedora 21: How to download files from my Galaxy S5
by Jim Lewis
Hello everyone,
This worked fine on my older Android Photon Q so I expected the same on
this new Galaxy S5. I plugged in the cable, found the mount point and,
as my guest1 user, located the filesystem and files. I saw they were rw
(read/write) and thought all was well. I tried to tar the whole thing up
and noticed errors. Here's some more detail:
laptop4 /run/user/1000/gvfs/mtp:host=%5Busb%3A001%2C005%5D $ fl \*.jpg

cp: cannot open IMG_20150123_163703_512.jpg for reading: Operation not

Not sure I have ever seen a situation like this. I can change the phone
from MTP to PTP mode but then all of the files do not show up (but I can
copy the files that do). I tried looking at this issue on the net but
all I got was noise.
This is on:
Fedora release 21 (Twenty One)
Kernel \r on an \m (\l)
Linux laptop4.com 3.17.7-300.fc21.x86_64 #1 SMP Wed Dec 17 03:08:44 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux
Thanks in advance for any help. I should have checked this right when I
got the phone but didn't think of it.

MAC address changes on every boot
by Randy Wyatt
I am running a fully patched Fedora 21 system. We are trying to give it a
long term lease in the DHCP server, but the MAC address sent changes on
every boot. The MAC address seen at the DHCP server is not actually valid.
The DHCP server is like Win2008 Server R2.
Any ideas?
Regards,
Randy

howto bypass initial setup?

I don't know why, but after rebooting my f21 server it goes to the 'initial
setup' screen. It's already all setup - how can I get out of this?

Re: SD card programing -
by J.Witvliet＠mindef.nl
Just a thought,
I did some experimenting with thumbdrives and (mini/micro)-SDcards.
Most laptops do not recognize SD-drives as bootable media, but when you put them into a usb-adapter they work OK.
Also making a card bootable on one adapter, does not garantee
That it will be bootable in a different sort of (multi slot) usb-adapter....

RE: WiFi restoration
by J.Witvliet＠mindef.nl
With only ten feet away, drop of signal because of distance isn't a serious consideration.
However, what Tim wrote does: If there is another modem operation on the same frequency, it will cause interference (like the old moiré patterns from physics-class)
If they use hidden ssid, it might be a bit harder to detect, but, moving them 4 channels up/down might be helpful, just like moving to the 5GHz band:
- those signals dampens more when they travel, thus causing less interference
- on the 5GHz band, you can use consecutive channels with less problems, on 2.4 you have serious overlap.

You could be in a dead spot for wireless reception - reflections of signals around the room you're in merge and cancel out where your computer's antenna is located. Try moving position a bit. I can produce this sort of problem when just a couple of feet from an access point.
You could be using the same WiFi channel as a neighbour, and the clash of each others signals messes up yours. Try changing your access point's channel. I've had that problem, too. Changing channels made a world of difference. I wish the interface that shows your nearby networks that you use to pick the one you wanted showed what channels were in use, rather than having to use some other debugging tool. It'd make setting up your wireless LANs a lot easier.
Some access points have an automatic option for them to pick which channel to use. Mine always automatically picked the worst one to use.
Logically speaking, it'd be scanning nearby networks, and avoiding channels that are in use; or, for where they're all in use, opting to re-use the channel with the weakest signal, presuming that it was the furthest one away. However, there's a fundamental flaw with this process - the access point can only determine best and worst channels for itself, your clients are in other locations, and which already-in-use channels are stronger and weaker, for them, will probably be a different set of channels than the access point's.

Hi,
A colleague sent me annotated (using Acrobat) comments on a pdf. I can't see them with zathura or evince. Is there some software that can read them?
Many thanks,
