Latest Raspbian (2017-07-05-raspbian-jessie) dd: /dev/rdiskX: Invalid argument on OSX and other potential issues with “apt-get” post install
So this morning I was trying to install the latest rasbian image onto an uSD card and was getting a strange error when I issued dd. I was using rdisk (BSD raw disk) device to speed up the image writing process (note: I don’t think you get this error if you just use /dev/diskX). The…

Getting the most out of plymouth or how to make raspbian jessie boot with a full splash screen
Assuming you want the fancy splash screen (ie you want to hide the ugly boot messages), add “quiet splash logo.nologo plymouth.ignore-serial-consoles” to the end of the single line in /boot/cmdline.txt file. This enables the splash screen. Now you need to choose one (I like spinfinity), so issue the following command to switch from default (bland grey…

Allow network to fail and be able to have the stream automatically recover. Allow the Pi to autostart on a particular stream when powered. Be flexible enough to potentially provide more than 6…

Since I’m serving my video content to our BrightSign infrastructure from a LAMP stack I ended up rewriting their bat file as a shell script. This enables me to host the shell…

sweet captcha site has been hacked – rhpop javascript
Fresh after recovery, I figured I write a small piece before I go home. If you’re seeing ad pop-ups or pop-unders from sites that load up something like rhpop-xxxxxx.js then you might have the sweetcaptcha plugin installed on your wordpress site. Let’s hope you’re the one who installed it — not the hacker :-), you…

JWPlayer 6.x plugin for WordPress….RTMP and HLS stream short code definition.
Not sure why this is such a mystery, but it took the better part of the day to troubleshoot. The main issue with forum posts is that people have the right idea/intention, but the forum software mistreats the actual command line/short code. Spacing really really (did I say really) matters. I’m assuming that you’re using…
