Since Intellipaat is in India and of course I am not, that means my classes run from 8:30 pm to 10:30 pm Monday-Thursday. Learning about Hadoop, Sqoop, Hbase, Flume, Pig, installing Hadoop clusters on AWS and all sorts of interesting topics. Soon I will be even more qualified to sit at home waiting for folks to respond to applications.
In my spare time I helped my daughter find and move into her new house, redo her bathroom, built shelves at my daughters and for my office, an end table, a breakfast tray, small step stool and some coasters. I also wrote a cookbook with over 85 recipes in it from my 46 years of cooking. (https://www.amazon.com/Recipes-Sunset-Cove-Michael-Ault-ebook/dp/B084T8XX1L/ref=sr_1_1?keywords=recipes+from+sunset+cove+kindle&qid=1581775548&sr=8-1)
So I am keeping busy.

I see the way they will make guns useless is to run up the taxes and regulations on ammo. Maybe I just need to tighten my tin foil hat but trusting politicians with something as critical as the defense of my family is not in my nature.
I was finally able to get my reloading bench setup out in the shed today. Of course it has been a while since I reloaded so I will have to take it slow and careful the first couple of batches until I can get back in the rhythm. I usually load 9mm, 40cal and .38 special. I don’t shoot enough 7.62x39 or .223 or 5.56 to make it worthwhile but I do have the needed dies should I wish to do so. I also have dies for 7.62x59 and 8mm Mauser along with the needed size primers, bullets and type powder
Anyway, I will take some shots (with a camera)when I do some reloading and put out a how-to when I get back into it. Keep your powder dry!

I am also pursuing a screenplay with my Suppressors series. In speaking with a producer he felt it would make a great TV series. So here goes...of course much like Arthur C. Clarks The Sentinel was the germ of the idea that triggered the entire 2001 A Space Odyssey franchise, so is my first book in this series Suppressors: The Shattering seemingly triggering an avalanche of ideas for series plots. I will try to keep you posted as this progresses.
I have also submitted my other books and few short stories from my Seeds of Wonder anthology for consideration as movies/TV series. Time will tell.
Right now I am dealing with undefined issues with routines in PL/SQL libraries. I will keep you posted on my status.
Recently I was moved from FlashSystems/Oracle work into Financial Systems/ Blockchain/ FlashSystems/Oracle work. Loads to learn. I will be attending ETHDenver, an Etherium hackathon. Something tells me I will be one of the oldest in the room at most of the meetings.
I have submitted presentations for the IBM series of Technical Universities in Cairo, Dubai, Brazil, London and Orlando. If they are accepted I will be very busy in the March/April time frame. My paper was turned down for Collaborate so I guess I will be a booth bunny.
That is the news that is fit to print, see you around the blog sphere!

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.

Anyway, will be posting my progress. The
