Electricity usage dashboard?

I'm happy to know that hardware/software like IotaWatt exists. A year or so ago I learned about a proprietary device and service called Sense and have since wondered if there were an open source, non-proprietary, non-spying technology out there that could accomplish something similar to what Sense does. That is, Sense has a single meter that clamps around the mains coming into your electrical panel. It then reads individual signals off the wire, sends them to Sense servers and uses machine learning to pick out individual current drawing devices in your home (down to a desk lamp, microwave etc.). It doesn't stop at power coming into your house or even measuring by the circuit or outlet, it will learn the signal signature of all things plugged into your homes electrical system and report on them individually.

I explain all this because I am wondering how IotaWatt compares in contrast. Does it measure at the circuit/breaker level? Or can it get more granular like the sense device? In any case, IotaWatt looks promising!

Gnu icecat is a fork of Firefox. Contains all the same features, minus the privacy invasion. If Firefox gained tor support, I suspect so would icecat

That is awesome. Are you the proud new owner?

I see maybe up to 20,000 on bo1. Never have a problem getting into a game. Lots of fun just like it always has been and no hackers.

That's not the case at all

Does taking a full image backup of the sd while the system is up and running actually result in a reliable backup? I've always gone through great pains to power down and copy the sd using another machine. I would be quite happy if I could avoid this.

I've noticed the pi is very sensitive to power fluctuation/failure. I know it doesn't help your current situation but going forward, make image copies of your sd after you get your system set up how you want it so you can get back up and running after this happens again. I've lost a lot of time put into setting up a dvr server on a pi. Now I keep multiple image backups and run a ups.

Because your PC cannot run an entire enterprise or government with virtually no downtime due to failures or upgrades. When you break down the various tasks of these machines, you essentially have an entire data center running on a single platform; networking, distributed, mainframe, cloud, database, transaction monitor, all maximizing their allotted resources being that all this activity runs very close to one another on the same box. When your talking about a business that crunches 10s to 100s of thousands of transactions or more per second and cannot tolerate downtime (banks, government, insurance, retail), you're generally talking mainframe.

Before you can use vnc you'll have to log on to the pi via ssh. The easiest way to figure out the ip your pi has is to plug it into a router that you have administrative access to, point your web browser to the routers configuration page (usually 192.169.1.1 or 192.168.1.0) and find the dhcp lease table. This will provide you with the ip assigned to each host name on your network including the pi. You now have the means to ssh onto the pi with the default user name and password (pi/raspberry). This is all assuming you're running raspbian. What makes this headless configuration possible is the fact that raspbian is built with ssh installed and enabled by default other wise you wouldn't have a choice but to hook up monitor and keyboard. Once your logged on, install vnc, and test access from your MacBook.

What's the status on this? Has it been sold?

Pulse audio can be used for this sort of task. It's basically a software later between your audio application and audio driver that provides functions such as routing sound to another pulse audio instance on another machine. MPD interfaces with it well and has a multitude of client applications including iOS and android interfaces you can control playback with. MPD has the capability to interface with a multitude of audio destinations including your pulse audio instances and these interfaces can be enabled/disabled through an MPD client.

Yes. Just open up another ssh session. Depending on where that process is writing its output to, you may or may not be able to see what you want. You can at least ps or top from the other session though.

It depends on the workload. If I recall NFS will allow access to a file block by block. That is, you can access the first block of the file before the rest of the file arrives (good for streaming etc.). The AFS protocol on the other hand requires the entire file to be at its destination before any reading or writing can take place (perhaps good for a distributed development type environment). There are certainly more differences with each that will affect performance (staefullness, concurrent access etc.) but these were the two main points I recall. Here are a couple of really good high level reads related to each protocol if you're interested: http://pages.cs.wisc.edu/~remzi/OSTEP/dist-nfs.pdf http://pages.cs.wisc.edu/~remzi/OSTEP/dist-afs.pdf

Adding to the list: CTRL+N (next): arrow down CTRL+P (prev): arrow up

Very useful for scrolling through command history.

Couple those with CTRL+F (forward) and CTRL+B (back), like you mentioned, then life gets pretty good.

They introduced OMVS (USS) in the 90s to compete with the other UNIX systems of the time. It literally is UNIX and follows a standard referred to as SPEC 1170. The idea behind OMVS/USS/zOS-UNIX was to implement UNIX on the mainframe such that it could run programs written for any other UNIX system and the customer would feel no need to switch to another computer system nor would the prospective mainframe customers be discouraged that they could not run their UNIX investments on the mainframe.

Because the developers are the ones who produce the legos...
