    PiHole LXC Container Proxmox CentOS7 

    Deploy an LXC container with the CentOS7 image.. 2G RAM, 8G storage, 2 CPU cores.
    I added a DHCP reservation for a static IP.

    When at the console for the CentOS7 LXC instance:
    Install pihole..
    curl -sSL https://install.pi-hole.net | bash

    PiHole

    Defaults are pretty good, just pick a good forwarding upstream DNS server. Google, Cloudflare, etc. The installer will install prerequisites. EPEL, REMI, bunch of packages, and run through everything.

    When the install completes, it will display the admin password ONCE. Take note of this.
    Reboot the container and run the installer again:
    curl -sSL https://install.pi-hole.net | bash

    It may ask you to upgrade PHP, go for it.
    It will then ask you if you want to update or reconfigure. If you were happy with the settings from last time, just hit update.

    When this has completed, you should be able to access pihole from http:///admin

    Remember to add in conditional forwarder for your internal domain name into the Settings under PiHole admin, and possibly add more upstream DNS servers (including your own router, perhaps?)

    When done, you can test it by going to your computer and trying to resolve a name against it..
    $ nslookup http://www.bbc.com 192.168.1.25
    Server: 192.168.1.25
    Address: 192.168.1.25#53

    Non-authoritative answer:
    http://www.bbc.com canonical name = www-bbc-com.bbc.net.uk.
    www-bbc-com.bbc.net.uk canonical name = bbc.map.fastly.net.
    Name: bbc.map.fastly.net
    Address: 151.101.52.81

    Now update your DHCP server to issue this IP as the primary DNS, then grab a new lease on the client (restart/toggle wifi/ipconfig release etc).

    I personally convert the container to a template within proxmox at this point.

    Vizio soundbars and TVs 

    i had both my Vizio 70” p702ui-b3 tv and soundbar stop powering on. The TV had 4 bulging capacitors on the power board, and the soundbar 1 (C21 I think it was). Replacing them is a beginners soldering job, and only costs a few dollars. It’s about $90 for a multimeter that works with capacitors for testing electronically. You can eyeball it, but the capacitance on the dead ones are off and the V rails are all inaccurate.

    Tags: 2012 Mac Mini, CableCARD, HTPC, Intel 4000, WMC   

    Divorcing my cable TV provider… almost.. HTPC, CableCARD, Windows Media Center 7. 

    Late 2012 Mac Mini – Intel 4000, Windows 7 on BootCamp, OSX partition as low as it can go. Color washed, flickering, etc.

    For me, turning off the stuff in the graphics settings that automatically adjust things both helped my color wash and the flickering.. a little. Only a little on the flickering. Intel say a fix is on the way.

    Go into the graphics settings for your Intel HD4000. Go to Media, then Image Enhancement, and uncheck the Adaptive Contrast Enhancement.. play around with the others, like color correction/etc.

    Hi All

    A fix for this issue has been checked into the latest driver. We should be posting it to Intel Download Center within a few days. I will update this thread with the driver links once it has been posted.

    — POST WILL BE UPDATED WITH FULL INFORMATION ABOUT IT ALL —

    — I WAS USING A CUSTOM BUILT HTPC BEFORE TODAY, AND I AM STORING THE PROBLEMS AND SOLUTIONS I EXPERIENCE ALONG THE WAY HERE BEFORE I HAVE THE FULL POST READY —

    Update

    I’ve since moved. Dumped the whole thing. Forced to take almost basic cable with Internet connection. Bizarrely, about 25% cheaper to. I now have this Comcast box doing HDMI pass through on my Xbox One. Seems to work well. I avoid all the Kinect crap, but I do use Xbox SmartGlass on my iPhone to control it when I don’t want to use the XB1 controller.

    NetFlix is on there. Amazon Instant Video is on there. Same with other stuff for sports, but you definitely don’t need TV. Pity Xfinity isn’t on there yet.

    Operating systems 

    There will come a time when our operating systems are a managed, hosted service. It will be upgraded like an mmo; through patches. It’ll be a subscription based service but will run on demand, with your pc being some remote hypervisor. I’m not sure I’d enjoy that.
