I installed the new CPUs and the new memory in both servers, using new heatsink thermal paste. The paste comes in a little injector looking thing exactly like the barrel end of a hypodermic. The paste is supposed to be for a single CPU install, but let me tell you, there is more than enough in a single applicator for two CPUs. Anyway, I got the new memory and CPUs installed and sealed up the servers and switched them on. Expecting to see that each had 2-quad core servers running at 3.16 Ghtz and 32 GB of memory, imagine my surprise when one showed up with a 2.66 and a 3.16 Ghtz CPU. Yep, they sent me the wrong CPU, and trusting me didn't check out the fine print on the CPU itself so here I am with a freshly installed CPU that was identical to the one I removed. Okay, so I needed to remove the lower speed CPU, call the supplier and get a replacement with the speed I asked for. Easy right? Here is where the fun starts.
Remember that heat transfer paste? Well when it is new, it is extra gooey and it turns out if you use the whole little injector on a single CPU a lot gets squeezed out to the sides making a mess of the CPU pad area and, unless you are very careful, it can easily get onto the CPU install pad itself. The problem is that the CPU install pad is actually a bunch of small hooked wires so you can't wipe the stuff off, you can't brush the stuff off, in fact the only option I can think of (now) would be to completely remove everything from the mother board, get some electronics spray cleaner and have at it. Unfortunately I tried wiping and then using a very fine brush to remove the embedded paper towel and the remaining paste. This resulted in many of those fine little hooked wires becoming fine little out-of-alignment straight wires. Scratch one CPU socket. Luckily Dell 2950s are still fairly available and I was able to order a replacement server for less than $200.00 delivered to my door. The replacement only had one 2 GHtz quad CPU and 4 GB of memory but that wasn't a concern.
So today my new-used server arrived and I gutted my old one to rebuild the new one in its image. Transferring the dual 4 GB HBAs, hard drives and remote access port from the old to the new and installing the just arrived quad 3.66 Ghtz CPU along with the existing one I had from the first attempt and using one of the heatsinks from the first server. Needless to say I was careful with the thermal transfer paste. Now I have two servers with dual Quad 3.66 GHtz CPUs and 32 GB of memory and they are both running Ubuntu 16.04.1-64 bit server software. They are talking to a 5TB mini-SAN through dual 4 GB HBAs. Now on to the Oracle installs!
I also got the replacement controller shield card for the Anet 3-d printer, but, before I install it I have to verify every single connector is set up correctly. There are three sensor cables, 5 motor control cables and 3 axis motion end stop cables that all need to be carefully checked for shorts in the Dupont connectors. Did I mention I hate Dupont connectors?
I also got and installed the green lasers in the 3-d scanner, but need the printer to make some better holders that allow x and y axis calibration of the lasers themselves. Otherwise you get cylinders inside of cylinders and other scans turnout really weird.

I am also in the process of learning the ins and outs of 3D scanning and printing using a Ciclops scanner and the ANET A8 DIY 3D Printer. Of course things are not off to an auspicious start. The primitive mounts on the Ciclops for the lasers cause issues with focusing and calibrating the lasers, I hope to have that fixed with some new laser mounts once I get the Printer working. In addition I have ordered some replacement green lasers for the red ones it currently uses. The CMOS in the camera used it much more sensitive to Red and you have fewer scanner issues if you swap out red for green lasers according to the experts.
The ANET A8 DIY printer is whole nother story. I assembled it over the course of two days, then calibrated it, did the bed leveling, checked that the extruder and heated bed worked as they were supposed to and then, not even half-way through the first test print the Mosfet on the control board for the heated bed fried, frying the control board. I have ordered and obtained a RAMPS 1.4 upgrade control board and am now just waiting on the DuPont connectors and Dupont crimper I need to complete the upgrade, at my own cost of course. The reason at my cost is because GearBest, where I bought the printer has crappy support. I have also purchased an upgraded power supply. These are suggested upgrades from long time A8 users.
I contacted GearBest to get a new board since this was literally less than a week since I got the printer. They said I obviously did something wrong and it was my fault so they wouldn't replace it. They offered me a generous 200 points (about 4 USD) for my trouble. This is the second time their support has been shall we say less than stellar. The first time was with a G2 mini-computer I bought from them which was DOA, I immediately notified them of this, they marked the report as "processing". It has been a year since then, and I reminded them to which they said since it had been a year, they couldn't do anything! In short, don't expect good client service from them, they are just a clearing house for cheap Chinese electronics, toys and games.
Well, I will keep you posted on progress.

To whit, critiques of works in progress. Usually seminars provide critiques of work in progress, work you did at the seminar or perhaps a pitch or proposal you created. I guess I have to agree with my wife (please don't revoke my man card, but after nearly 43 years of marriage I have found she is right, even when she isn't.) that I tend to do two things:
1. Not stand up for myself
2. Let other people walk all over me
Now I guess those two are closely related. I tend to believe I pick my battles, if it isn't going to make a difference in five years is it that important? Anyway I have found I tend to allow the other seminar attendants to go first. I like to think I am being tactical, figuring out who gives the best comments, to whom I should pay attention and who has spent too much time alone with their cats. Have you noticed most female writers seem to be inordinately fond of cats? What this results in is that I end up being critiqued near the end of the seminar.
Now, if all things where even and fair each attendee would get exactly the same amount of time. For the most part the seminar leaders do try to be fair. However many times they are up against hard stops or if there are guest speakers, the guest speaker's schedules. It seems no matter what I try, I end up at the end of the day or coming up against a secondary speaker. I even completely switched my seating around in one seminar, only to have the leader reverse the order.
So, from now on, in future seminars I will the first with my hand raised (or however they say to indicate preference) to volunteer to be foisted on my own petard (whatever the heck a petard is, and no it is not the latest Captain of the Enterprise, that was Picard.) So I hope by being more direct and forceful I can get my fair share of criticism. Hmmm....that sounds not quite right. Anyway it will also mean I get to respond to the criticism.
You see at the seminar I most recently attended they made several comments and questions about my work, but then when I was supposed to get to respond, the guest speaker showed up and I wasn't able to explain how I was correct and they were not (well, they were wrong on some of the facts they were sure of...) anyway I fell that they should make way for the paying clients not the free guests. Besides, the guest spent most of the time talking about her cats, if I want that I will peruse Facebook.

My biggest problem has been getting Oracle Linux to install, seems you need a Linux install to create a Linux install disk from the ISO...or maybe I am just getting too old to deal with it...
If anyone has a OLE install disk they want to send me I would appreciate it!
Reached one of those milestones, I am officially old enough to withdraw from my 401K without penalty tax. Don't know if that is good thing or not!
Published another Novella titled "The Emerald Curse" the third in a series with my Hero Rex Franklin. IN this one he gets pulled into a search for Spanish treasure while installing a tsunami warning network in the Turks and Caicos. You can see it here:
The Emerald Curse
I am still trying to decide if I should self-publish, look into Kindle Scout program or try traditional publishing with the first book in my new series: Suppressors: The Shattering. It posits a world where magic is and always has been real, but it is being suppressed and what happens when this suppression begins to breakdown...
Made it through this years snow fall had to drive in from Atlanta on Friday night just following the storm in. Had a few minor scares coming over the hills into Helen, Ga and down the mountain on the other side but nothing I couldn't handle. Then we just hunkered down up here in Sunset Cove until the snow melted. The driveway and roads are all clear now.
Well, as I make more progress on the cluster I will post. God bless.

The book is in support of a Ghost and History walk we are trying to pull together for October and November for the Wherehouse of Murphy, come on by and sign up!
My biggest issue with Black Rose Writing was the price point they placed on my book. "Prelude to Darkness" is a 250 page book and they placed a $17.95 price on it. People just will not buy that expensive a book unless it is in the 300-400 page or longer range. I put the book up for a price point of $9.99 which could have been less except it would have generated negative returns in some of the expanded markets.
Anyway I hope that people will find the book more accessible at this new price point.
I am attending the New York Pitch conference this month and hope to sell my new book "The Suppressors" about the premise that magic is and always has been real but a group known as the Dark Adepts has been suppressing it using suppressor portals, but what happens when their network begins to break down allowing wild magic? I also have book three of my Rex Franklin series with Rex installing a tsunami warning network in the Turks and Caicos and getting pulled into a search for lost Spanish emeralds just about ready if they allow you to pitch more than one maybe I will pull it out as well!
I will be traveling to Ft Worth, New York, Raleigh, Orlando, Cannes France and then going on a cruise all before Thanksgiving. Something tells me I will be ready for the holiday downtime.
