Save battery by slowing data

The title sums up this post pretty good. If you've got Android, more specifically a variant of Android that let's you really tweak your settings, like  Cyanogenmod

Do you live in a place with 4G or did you just travel somewhere that has 4G? If so and you want your phone to actually last the whole day or two toggle the speed to 2G (it will actually toggle to not 4G which is often 3G). I find that if I don't 4G drains my battery very quickly to where I worry about running out before getting home or to a hotel while travelling.

The trade-off is great if you're just checking email and getting directions. When you want to stream video etc, just toggle the speed back on.

TODO: I'll get picture of my quick-bar power settings so people can see what it looks like.

Tip 2: Want to use Wifi on a plane, toggle to Airplane mode, then toggle wifi back on. PS: Airplane mode also breaks many in program ads.

Upgrade notes Ubuntu 12.04 to 14.04

Just a few things I encountered in my upgrade on my Zotac Zbox going to from Ubuntu Precise (12.04) to Ubuntu Trusty (14.04)

  • Couldn't get it to use an iso as the upgrade material since there's no alternate cd anymore, so did an online upgrade which worked fine.

Fixes:

  • Atheros driver is way better, I went from 1 Mbps to 4 Mbps on Speedtest.net, nothing else changed in my network, the latter speed what I always got from other computers.
  • Streaming video full screen no longer requires gpu acceleration to be disabled.

Bugs (related):

  • nouveau driver hiccups on sound every few seconds when streaming videos
  • Nvidia Ion graphics/sounds always transmits sound on HDMI even if you switch to analog. In my case this provided a weird problem, where I couldn't use analog audio to bypass the previous bug above. See fix below...

Workarounds:

  • Installed the Nvidia drivers, which had major issues in 12.04 (screen blank or not lined up with monitor/tv) - works great now
  • Forgot that Amazon Prime streaming require hal for flash drm get it from this  ppa
  • Chromium and Chrome no longer work with Adobe flash from the repos, you need pepperflash
    sudo apt-get install pepperflashplugin-nonfree
    sudo update-pepperflashplugin-nonfree --install
    
  • If you're using Apache pay attention to the 2.2 to 2.4 upgrade, syntax of allows and conf file names changed and are important.
