hpr1805 :: 56 - LibreOffice Impress - Styles and Objects 1 - Presentation Styles

Presentation Styles and their use in LibreOffice Impress


Hosted by Ahuka on 2015-07-03 and released under a CC-BY-SA license.
Listen in ogg, spx, or mp3 format. Series: LibreOffice | Comments (0)

We have previously looked at Styles for Writer, and for Calc, and now it is time to look at them for Impress. You may recall from both Writer and Calc that we saw it is important to know that Styles live inside of Templates. So any time you change a Style you needed to make sure it was saved inside of a Template, and if you wanted it to be generally available in all documents or spreadsheets you needed to be sure to make the change inside the Default Template.

hpr1800 :: YouTube Video Subscriptions

How to subscribe to and watch YouTube Video series, with suggestions


Hosted by Ahuka on 2015-06-26 and released under a CC-BY-SA license.
Listen in ogg, spx, or mp3 format. Comments (2)

Although my wife and I have a Cable TV subscription, I have maintained I could give it up easily because so much of what I am interested in is online anyway. For many people that might mean Netflix or Hulu, but for me it means YouTube. This is the golden age of narrow-casting, as opposed to broadcasting, because YouTube gives so many creators the opportunity to find their own audience for things that dont appeal to the masses.

hpr1799 :: Posting From the Command Line on Open Social Networks

I explain how to post content from the command line on open social networks pump.io and GNU Social

Posting From the Command Line on Open Social Networks

You can post to your open social media timelines from the command line using API access. Why would you want to do this?

  • Script automated postings.
  • Bots
  • Post from terminal environments.
  • Post from wherever else you are without having to go to the social media site or to the client that you use to access it.
  • Trigger postings via voice command (what I do).

On GNU Social

Here is the basic format for the command to post a message to a Statusnet / GNU Social timeline:

curl -s --basic --user <username:password> --data status="Hello World" --output /dev/null http://instance.domain.com/api/statuses/update.xml

And here is the script I use to post a message to my timeline, launched by a blather voice command:

#!/bin/bash

# SN account info
user=johndoe
pass='password123'

# a place to store the text message 
text=/tmp/message.txt

# Virtual keystrokes to copy selected text to the clipboard
xdotool key Control+c

# pipe text out of clipboard into the text file
xclip -o > $text

# rest for half a sec
sleep .5

curl -s --basic \
--user $user:$pass \
--data status="$(cat "$text")" \
--output /dev/null \
http://instance.domain.com/api/statuses/update.xml 

rm $text

exit 0

On Pump.io

On pump.io you have to install the pump.io software on your computer. You don't have to be running a server, you just have to have the binaries so that you can run the commands. I will not go into how this is done on this podcast, but there's a link to the pump.io website below and there should be installation instructions available there. Once you have the software installed, you also have to allow command-line access to your account and get the token for authentication, maybe authorize the user too:

pump-register-app -s instance.domain.com -P 443 -t CLI
pump-authorize -s instance.domain.com -P 443 -u username

Finally you can post to your timeline from the command line:

pump-post-note -s instance.domain.com -P 443 -p -u username -n "Hello World."

My script to post a message to the pump.io timeline, launched by a blather voice command:

#!/bin/bash

# a place to put the text. 
text=/tmp/message.txt

# --------------------------------
# Since markdown is possible, I run 
# the text through markdown to get
# a bit of formatting and save it
# as a separate file 
# --------------------------------
pump=/tmp/pump.txt

# Virtual keystrokes to copy selected text to the clipboard
xdotool key Control+c

# pipe text out of clipboard into the text file
xclip -o > $text

# run Markdown
markdown $text > $pump

# Post message
pump-post-note -s instance.domain.com -P 443 -p -u username -n "$(cat $pump)"

sleep 1

rm $text
rm $pump

exit 0

An Interview with Aaron Wolf of the Snowdrift Co-op project by David Whitman during LinuxFest Northwest 2015

Aaron Wolf http://blog.wolftune.com/

Snowdrift: https://snowdrift.coop About: We're building a sustainable funding platform for freely-licensed works. Our innovative matching pledge creates a network effect where we all work together to support these public goods.

Introducing Snowdrift.coop

Our matching patronage system allows everyone to support FLO projects with minimal risk and maximum impact.

Unlike the one-to-one matching used in traditional fundraising, we use a many-to-many matching pledge that creates a network effect (like the internet itself) so that we all reinforce one another. Unlike one-time fundraising campaigns that help projects get started, Snowdrift.coop pays out monthly to provide sustainability for ongoing work.

Before the times of modern market capitalism, creative workers were supported by wealthy patrons. With Snowdrift.coop, the global community becomes the patron. Instead of businesses deciding the options that we then merely choose from as consumers, we will support and actively work with projects that best serve the interests of the public.

hpr1796 :: Audacity - Chains, Notches and Labels

Some more Tips and Tricks when using Audacity

I expand some on Jon Kulp's show on using Labels in Audacity. Specifically, I comment on importing a Label track from a Tab separated text file.

I go on to talk about using Notch filters, a Nyquist-effect plugin for Audacity. Notch filters work extremely well on certain frequency centered noise like mains hum.

I follow up by talking about chains. A way of doing batch operations directly in Audacity.
