You maybe want a macro the seek to the next ALLCAPS word, then apply
your helpful emacs built-in function on that word, then repeat the macro
enough times to complete the whole document.

I'm not sure I fully understand what the requirements of your friend are 
at this point. Do they want a WiFi router, or something else?

I've been relatively happy with my R6400 from Netgear[1], but the built 
in OpenVPN doesn't play nice with anything except Windows. There was a 
recent patch that fixed a vulnerability for remote command execution, 
but largely it's been reliable. The last firmware release we relatively 
stable, but one of the previous releases only lasted about 30 days 
before it went haywire and required a reboot. The new one is only about 
4 days old now, so time will tell there.

I have a Linux workstation running behind the router and that receives 
connections for OpenVPN service that is installed there, and works well 
enough for me and all my mobile devices.

Re: [PLUG] recommended hardware question on VPN router

[brooks]

To connect anything via a VPN you would need to first know what the other 
side supports. For example, if you were conencting to an Amazon VPN 
endpoint in 2016 you could reference this:

[PLUG] recommended hardware question on VPN router

[logical american]

Can someone suggest good vpn hardware for a VPN client?  My friend has 
an account with a popular stock trading house, but he is now nervous, 
since so much hacking has occurred.

I did check one of the big local chain stores, but they only had 2 
routers for sale, supporting vpn.  I see 2 other chain stores listing a 
Linksys Gigabit VPN router, but not sure of their quality.

Any suggestions?

   Yes, this is correct.

   A regex is what I tried first, but apparently did not correct form the
expressions:
   Replace [A-Z]+ with [A-Z][a-z]+ 
Perhaps I need to group the replace regex with parentheses then use a back
reference with the replace regex? I tried that but did not have the correct
syntax.

Thanks,

Re: [PLUG] Emacs: convert all uppercase words to capitalized

[John Sechrest]

I got the impression that he wanted to have text of the form:

   This is a SET of words that have CAPITALIZED WORDS that should be
addressed by a mechanism to convert Capital words to go from ALL capital to
All Capital

And convert them to:

  This is a Set of words that have Capitalized Words that should be
addressed by a mechanism to convert Capital words to go from All capital to
All Capital

So It is not clear to me that the Capitalize-word mode does what you want.

I think this is likely a job for regular expressions.

Where you have to use the regular expression query and replace:

capitalize-region M-x ... RET
   Convert the region to capitalized form.
capitalize-word   M-c
   Capitalize the following word (or ARG words), moving over.
capitalized-words-modeM-x ... RET
   Toggle Capitalized Words mode.


Either give capitalize-word a numeric arg (via Ctrl-U), or use
capitalize-region (which isn't bound to a key here).

   I've also tried sed and perl (from web searches) and they're not working
either.

[PLUG] Emacs: convert all uppercase words to capitalized

[Rich Shepard]

   I've looked in both the emacs docs and the wiki and both show me that M-c
will convert individual uppercase words to initial capitalized words, but
I've not found the way to do this for all words rather than one at a time.

   Selecting a region prior to invoking M-c does nothing.

   A cluestick will be really helpful.

Re: [PLUG] Help with v4l2 Video Driver

[Erik Lane]

Thank you everyone!

it looks like I have it solved. It still has issues sometimes, especially
when there are breaks in the tape. (I mean where one recording stops and
the other starts. Looks like it loses tracking and that confuses it.)

So sometimes I have to redo a tape, but eventually I manage to get a
working version. Or I can input the audio in audacity and then merge it
back with ffmpeg.

I had issues getting ffmpeg to bring in the audio from the card. Even
selecting the hardware channel as specified in various pages I found online
doesn't do it. Using VLC I can record the video and audio usually, and once
I had to do it separately, but it worked. So while it might not be ideal
and it will take a bit longer this way, I'm done with trying to get it done
more efficiently. It will be quicker to just get it done now. Knock on
wood, but I think I have my specific problem fixed well enough to get the
job done.

Thanks for the input!
Erik
