HPR2039: Blather Configuration Part 0: Initial Setup
In this episode I walk you through the process of getting the Blather GNU/Linux speech recognition program running for the first time. Arch: On Arch Linux this is really easy. Jezra made a package build for the AUR so you can just install it that way. Debian: I wrote an installation script for Debian-based systems that installs the dependencies to build pocketsphinx, plus a few extra packages that I use continually when I'm running blather (xvkbd, xdotool, espeak, wmctrl, elinks, xclip, curl). It builds/installs the Sphinx stuff, pulls the blather source code, and puts some configuration files and a startup script in place for you. This should take care of pretty much all of the heavy lifting. I refer frequently to Jezra's usage notes on the Blather source code page at gitlab, so if you're trying to install this as I talk, you might want to follow along over there. The trickiest bit in the initial run is the creation and placement of the language files. I normally use a bash script for this, but on this first episode of the series I'm going to use the web-based lmtool to create the language files, just the way Jezra says to do on his usage page. He also includes my automated language updater script in the blather source code, though, so going forward I will be talking about how to use that script instead of the web-based tool. Blather Launch Script I use a bash script to launch Blather because I want to set several environmental variables: location of the pocketsphinx gstreamer libraries, default browser, default text-to-speech engine, and so forth. Having these environmental variables set means that I can use easy-to-remember shortcuts in my blather commands config file. Here is my launch script: #!/bin/bash # tell it where the Gstreamer libraries are export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-0.10 # set some shortcuts to use in the commands file #export VOICE="/usr/bin/festival --tts" export VOICE="/usr/bin/espeak" export CONFIGDIR="/home/$(whoami)/.config/blather" export KEYPRESS="xvkbd -xsendevent -secure -text" export BROWSER="chromium-browser" # add blather script directory to the user's PATH export PATH="$HOME/bin:/home/$(whoami)/.config/blather/scripts:$PATH" # start blather in continuous mode with the GTK GUI # and a history of 20 recent commands python2 /home/$(whoami)/code/blather/Blather.py -c -i g -H 20 Links Blather source code Blather Installation Script for Debian Jezra's website Sphinx Speech Recognition Library Sphinx knowledge base tool Learn about the $2 Microphone that I use for blather: HPR Episode 1812 Credits Music bumpers are from Kimiko Ishizaka's The Open Goldberg Variations: http://www.opengoldbergvariations.org/, used by permission of their CC0 1.0 Universal (CC0 1.0) Public Domain Dedication license.

HPR2035: Building Community
This is droops and this is also Hacker Public Radio. I love HPR and noticing our current need for shows, I put it on my list that I needed to help out. But what to talk about? Let’s talk about growing HPR. It is a cool show and project, but if the community does not grow the show will end. People run out of shows to host and others have to fill that space. I think we do a great job doing outreach to the community by going to conventions, getting mentioned in articles and magazines, and being cool with everyone. But as a community we could do a little more to get to the 4000 show mark. Even my lazy butt can help with these things. First, let’s bring more traffic to the site. To do this we need content, which is really all we have. But we need to be more clever with how we use it. We need to transcribe all of our shows. This allows search engines to better index our content and bring more people to our site. Maybe they won’t subscribe or even listen to a show with the content being readable, but they were not going to listen anyway by not finding us. This is a big chore and we would need a team with leadership to do it. We need more popular hosts (this sounds bad taken at face value) to guest host shows and mention HPR on their shows. We used to do this by sending in bumpers like “this is droops from Hacker Public Radio and we live whatever this show is. Hacker Public Radio is a daily show created by the community”. Let’s make a list of podcasters we want to guest host or mention our show and go after them. Speaking of guest hosts, let’s work on interviewing more people who will put our show on their blog/social media. We did this in the early days of Twatech with Moka5 and we got a lot of traffic from this. I do know that we already do this, but not everyone who listens contributes a show and this is an easy way to do it. What if we made it easier to record shows? Maybe have an Android/iOS app to record and submit shows from. We could have a tool to submit show topics or do a survey to find out what people are interested in. This may prompt people to record shows by knowing that someone would be interested in it. Someone could get some free stock photos (or better yet we could just take our own) and put show titles over the images to share on social media. People click on images. I will do this so that everyone can see my ugly face. On that note, how about a video that explains what HPR is. This may be a good droops project. That would be something awesome to share on social media. The website, which is a lot of work, needs to have related shows listed on each individual shows page. This will take a tag system and someone to tag all of the almost uncountable previous episodes. One of my favorite show formats is reviews of software/media. This is so much in our community to keep up with and HPR is perfect for this. Everyone should do a show about some unique software they use or a cool book they are reading or a cool documentary they watched. Five minutes about something cool would bring me into learning more about it. Currently my classes are watching a documentary about the Silk Road called Deep Web (http://www.deepwebthemovie.com/). I should do a show on it to talk about privacy, government, all the cool things it brings up. We have not gotten far into the documentary yet as we keep stopping it to have discussions. Also I love stickers, we should set up a store to sell stickers and t-shirts. Heck this is HPR, we should have tote bags. We can either sell them at cost or make a profit to pay for hosting or swag to give away. Hacker Public Radio is driven by the community and out community as a whole is much smarter than I am. Let’s put our minds together and grow our show.

HPR2032: How I Came to Linux
I tell the story of how I learned about computers and eventually came to be an avid Linux user. I've been using Linux as my primary operating system for almost 20 years now. My primary distribution of choice has always been Slackware, but I have branched out to some more "modern" distributions as well, particularly for workstation environments. I have been an HPR listener now for several months and this is my first show. I enjoy the podcast very much and hope to see it continue for many more years. Thank you to the administrators and leaders to make it all possible. And, of course, thank you to everyone that contributes shows.

HPR2030: Book Review: The Pocket Ref
Recorded this episode while suffering from some severe seasonal allergies, so please disregard any sniffing, wheezing or coughing that may have crept in. This is a brief introduction to the Pocket Ref by Thomas Glover. In this episode, I don't go into great depth of the books many topics, primarily due to the nature of the book itself.

HPR2025: Using a Smarphone as a microphone
Hello citizen of the Internet, my name is njulian, and in my first Episode for HPR I want to talk about an App called "Microphone". This App is available for Android in the F-Droid repository, link is in the Shownotes. All it does is sending the audio input from the microphone directly into the audio output. This causes horrible feedback loops, if the output happens to be the Phone's speakers. But if you plug a Male-to-Male 3.5mm cable into your Phone and the other end into your Computer you can use your Smartphone as a Microphone. Actually I am using this right now to record this show with Audacity on my Laptop. The reasons for that are pretty simple: I don't have enough free space on my Phone to record a show with Urecord and the other is that I was curious if this app really works. Well, actually there is not much more I could tell about the App. It has no menu, no way to customize it, and as you can hear no noise suppression. That's about it, thanks for listening. The App: https://f-droid.org/repository/browse/?fdfilter=microphone&fdid=net.bitplane.android.microphone The Cable: https://en.wikipedia.org/wiki/Phone_connector_%28audio%29 Links https://f-droid.org/repository/browse/?fdfilter=microphone&fdid=net.bitplane.android.microphone https://en.wikipedia.org/wiki/Phone_connector_%28audio%29

HPR2024: Remapping Keys with xmodmap
In this episode I talk about how I tried to implement an idea that my son had when we were talking one day. I was complaining about file names with spaces in them, and he asked what if the computer automatically changed the spacebar so that it made underscores whenever somebody was trying to save a file? I thought this was a great idea. I even thought of a way implement it, though not quite as magically as he had envisioned. My solution involves the use of the command-line tools xev and xmodmap, and one blather voice prompt to launch the xmodmap command that will remap the spacebar to make underscores instead. Maybe somebody a whole lot smarter than me can figure out how to make this happen automatically whenever a save dialog box is open. First you need to find the keycode for your spacebar. Run the xev command and then press the spacebar to see which key code it is. Here's the output on my laptop: KeyPress event, serial 48, synthetic NO, window 0x4e00001, root 0xc0, subw 0x0, time 116149126, (-739,-226), root:(448,358), state 0x0, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XmbLookupString gives 1 bytes: (20) " " XFilterEvent returns: False As you can see, my spacebar has the keycode of "65." Now we use xmodmap to reassign keycode 65 to make underscores: xmodmap -e "keycode 65 = underscore" Now to test it out. While xev is running, press spacebar. Notice that now when the spacebar is pressed it makes an underscore: KeyPress event, serial 57, synthetic NO, window 0x2600001, root 0xc0, subw 0x0, time 116190619, (-520,-247), root:(667,337), state 0x0, keycode 65 (keysym 0x5f, underscore), same_screen YES, XLookupString gives 1 bytes: (5f) "_" XmbLookupString gives 1 bytes: (5f) "_" XFilterEvent returns: False And to change it back: xmodmap -e "keycode 65 = space" Now whenever I want to change the spacebar to make underscores or switch it back, I speak one of the following commands, which are in my blather configuration file. MAKE UNDERSCORES: xmodmap -e "keycode 65 = underscore" MAKE SPACES: xmodmap -e "keycode 65 = space" Links xmodmap man page: xmodmap is a utility for modifying keymaps and pointer button mappings in X xev man page: use xev print contents of X events Video Demonstration
