For those who may have missed the original article in the Swiss Das Magazin, here's a reprint regarding the role Big Data played in the Trump election campaign. https://motherboard.vice.com/en_us/article/mg9vvn/how-our-likes-helped-trump-win Warning: it's a long read, and very enlightening...

Sounds like you have it covered. We less smart guys are restricted to adding matching battery packs for more run time. My primary DNS is a centos VM and secondary DNS is a RPi3; this way only one should ever go offline at a time; no issues so far. My configuration is pretty simple, but I'm...

As a temporary fix you may want to plug your UPS into a second UPS. I had good success with this arrangement but the ugliest transients will still get through. I bit the bullet and upgraded to a 5000VA APC rackmount unit which does flow-through power conditioning and is immune to incoming power...

This page provides a list of firmware and driver updates re: KRACK. Don't give up hope on your Dell just yet...

or a managed switch. But, same as VLANs on a router, the learning curve can be steep, although the price comes down to <$100.

For every 3dB of antenna gain you double output power in one direction at the cost of halving power in another direction.

I studied up on how the consumer wifi companies exploit marketing jargon, then ditched my wireless modem in favor of a wired EdgeRouter Lite and access points. Here's the FCC maximums (https://www.air802.com/fcc-rules-and-regulations.html) for 2.4 and 5gHz. Legal maximum of any 2.4 radio is...

One EdgeRouter Lite will do what you want: provide 2 LANs each with their own DHCP and give you the ability to manage traffic between them as required.

My Edgerouter Lite does this by default. I had to implement firewall rules to prevent LAN 1 from seeing LAN 2.

1/3 mile...? I live on a farm and get my internet via wifi from the provider. I have a dish on the roof pointed at the tower 5 miles away, with trees in the way that mess everything up in a good wind. I've worked with the installer to optimize the signal, and I know it's 2.4GHz... 1/3 mile...

My rack is in the attached garage, so noise and heat are non-issues (area is used as workout room, spare (beer) 'fridge, dog food storage, etc.). That said, the 2950 doesn't see much use because it does heat the space up to the point of being uncomfortable, but I leverage this as an excuse to...

You can control the color of each LED separately. They used to be long shift-registers that simply pass the info on to the next light in the string. The new ones still pass the data but will ignore it if it's not addressed properly. That's the simple view... I think it sends a really long data...

Thanks, I think... I'm more interested in the fancy new individually-addressable-RGB LED light strips hitting the market. Cheap entertainment.

Funny you should say that... There's 2 brand new RPi's on the table waiting for me to get my poop in a group. Amazing little critters...

I think I bought mine through an ebay deal listed here... and I got the firmware link here as well. Y'all are a very bad influence... It's all your fault. :) On the other hand, my wife is happy I'm spending so much time in the house.
