What Are You Doing Right Now

USB Battery Bank... Curious... I looked around for a 12v battery a bit today. Want something light enough to carry with my radio.
It will run on 8 AA batteries, but not the greatest. I do have a decent supply of 18650 batteries. just need to make a decent case.
My design will support 5v 5a (2x USB at full 2a draw each with spare) and a 12v output @ 5a
All this is from 4 quad parallel packs of 18650's (4x 3.7v packs of 4 batteries)
It's going to be gloriously overbuilt and well protected & filtered. The chinese "built to the lowest dollar one hung low fire hazards" are not to my taste.

@gjacobse I bought one of these one hung low things and I was horrified at the construction, let alone the insane voltage spikes and drop outs. It's 12v output is filthier than a lady of the night on east hastings in Vancouver

Working on an Elastix 4 install onto CentOS 7 on Digital Ocean. Fingers crossed that this actually works.
-
If this ends up working, this will finally make our CentOS count on DO higher than our Ubuntu count.
-
Why does no IaaS cloud platform offer OpenSuse? Argh. Pisses me off.

We should talk... I'd be happy to help test. and I have plenty of usable 18650s

@gjacobse what kind of amperage / run time are you after?
I hope to have a prototype built this fall

I haven't done the math lately, but the 817 will run on 8 AA batteries, I want to say that there are some pre-made packs that are only 2500mAh at 9v. Trying for the highest power density practical for weight as I may lug this out on a hike.

@scottalanmiller I just want to know why you're so anti-zfs and anti-FreeNAS. The GUI is awesome.

Where did the idea that I am anti-ZFS come from? People repeat that all of the time. I was promoting ZFS a decade ago. I probably am more responsible for introducing it to the SMB market than most anyone. I was pushing it years before people had any idea what it was or how to use it. I have been working with ZFS since Thumper. I actually got access to Thumper before general release. I've seen people say this many times, yet I'm an ardent promoter of ZFS when it makes sense.
As far as FreeNAS, the GUI is irrelevant if it puts you at risk. What is the purpose of an easy to "set up" system that you depend on if it is not easy to maintain and fix if something fails? Easy to use GUIs are evil if they get you into trouble and don't provide the way out.
Did you read The Jurassic Park Effect that explains why NAS OS (not FreeNAS specifically) are categorically a bad idea? Storage isn't a game. It's not something that you can trivially replace should you not know how to fix it when things fail, and things do fail. You don't use "simple to get up and running, hard to fix" in production, you want "hard to get running, easy to keep reliable" instead.

I was being facetious. It was a reference to the spiceworks thread today about the guy using FreeNAS and a SAN.
Didn't mean for you to have to write that large reply.

LOL, thanks

It sucks, every time I try to go down the path of "Let's figure out the right technology for your specific scenario.", someone immediately attacks me for hating whatever product they are trying to push. Not using product X for every scenario without even considering client needs must mean that I hate that product, hate the person in question and hate the entire technology around it. And the moment I try to point out that something is too costly, they will tell me to stop wasting money (um, I just told you you were spending too much!) or if I mention needs they will point out that I, alternately, have no idea what a small business is like and/or have no idea what a large business is like.
It's so frustrating that people will say anything to try to discredit you over there. I think that they just guess what size company you are with and try to say that you know nothing about "the opposite one." I have no idea how other people post there, if I didn't have over a quarter century in the industry and have worked with many companies at both ends of the spectrum (literally two person companies to multiple in the Fortune 10) I would be automatically be discredited everywhere for not being in a company of the right size.

I used to read a lot there, but lately I've just been participating on here (I still read stuff on there, just don't post as much). If I had a dollar for every time someone recommended Ubuntu because "it's better for desktops" I'd be a millionaire. It's sad because a lot of the time the people generally don't have an idea of what direction to take and they are just guessing, so catering to their guesses makes it worse.

I think that one of the biggest behavioural things that is happening, but obviously I am only guessing, is that people do a lot of "do what I did" not because they have any reason to believe that what they did was the right thing but rather because they want other people to repeat their behaviour because it reinforces, in their minds, that what they did was correct.
Basically, if I jumped off a bridge I want you to jump off of it too so that it feels like there is agreement that I made a good decision in jumping. It is a form of reverse-reasoning where humans like to justify decisions that are already made when they did not take the time to decide if they were wise decisions before having made them.
It is well covered in "Predictably Irrational" and I see it constantly. It's not that they want others to fail, they just want "justification" for their own decisions since they lack any reliable way to defend what was actually a decision made without clear rationale (not that the decision was wrong, just that it was haphazard.)

I've seen you talk about that book before. I need to get it.

Great book, probably the best book that I have ever read that helped me to understand people (and myself.)

Elastix 4: Anyone worked with it and notice that under the hood the packages are all Elastix 2.5, but deployed to CentOS 7?

No, but it is what I expected.
Elastix was abandoning the FreePBX backend. Version 2.4 was supposed ot be the last version. Elastix 3.0 was supposed to be a better thing.
Then it all went to shit. They rushed out 2.5 and it breaks working 2.4 systems that attempt to upgrade.
Then they came up with this idea to get money from KickStarter to get it ported to CentOS 7 and they would call it version 4. Note the term ported.

No updates since March, which is not THAT long ago, but it is pretty long in terms of a port
