OMG! News Flash! SalesForce & TITSUP

HAHA  OH MY GOD!!!  Thanks goes out to Simon Sharwood and The Register for this article about a Salesforce Outage.

I simply MUST quote their update:
"One of Salesforce.com's European instances is enduring a lengthy un-planned PITSTOP incident – that's a Partial Inability To Support Totally Optimal Performance, a whit below our other status indicator of a Total Inability To Support Usual Performance or TITSUP."

HAHAHAHAH!!!!!  OH MY!!!!  TITSUP!!!!!  Never have I seen TITSUP and Salesforce on the same page before.  SO apropos, So right.  Thanks for the Thursday morning laugh!!!

**Disclaimer - I am not a fan of Salesforce, its abysmal development environment, its incomplete programming language APEX, its poorly thought out data structures and generally the whole Salesforce concept and system.

Oracle VM VirtualBox - Just a Misleading Error Message

Three weeks of fighting a "cold from hell" gave me time to think about my little project to automate a search for meteor photos.  Sure, I have a PINE64 on order.  Sure, it may be delivered later in March.  Sure, there may be a flavor of Linux available for it sometime soon.  Sure, I may be able to build ImageMagick and other tools I need for the Pine64.  Sure, the performance may be acceptable for my goal.  Crap, no planned PXE/net-boot planned.

What if...  Let's see...  a complete Pine64 compute node with 1GB Ram and the OS on an 8GB flash drive will cost roughly $35 accepting a lot of "maybe" assumptions.  Let's remove the assumptions and calculate the cost of a good old AMD or Intel processing node.  Looks like a 64 bit AMD based system with 4GB RAM, with PXE boot will run about $85.

So...  I decide to emulate a 32 bit Debian text-only install on an Orable VM Virtual box using 4GB Ram to sort-of emulate the AMD solution.  Which gives me an idea for a new word...

umulate - An emulation that is not exact; allowing certain differences for the sake of brevity or simplicity.  "I am going to umulate this Debian install; the real machine will not have a hard drive, but will boot from a flash drive."  But...  I digress...

BUT SMACK...  An error pops up from Oracle Virtualbox when I try starting the virtual machine...

Failed to open a session for the virtual machine DebianPNode.

Under "Details" it read...

VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)

Well, after some research and comparing this virtual machine with the operational virtual version of Debian, I arrived at a repair that seemingly has nothing to do with the error.  I changed the Base Memory for this Virtual machine to 3072 GB and SHAZAM.  No more error.  Keep in mind, my machine has 8 GB and runs a pretty lean install of 64 bit Windows 7.  Why this misleading message popped up, I have no idea...  but reducing the Virtual machine's Base RAM fixed the problem.

Teaching an Old Dog New Tricks.

Regardless the age of an old programming dog, new tricks are pretty important to learn.

My initial success with night sky photography with my Canon EOS Rebel T3 tumbled in my mind over the last few days.  Recorded remnants of a thought from a few years ago popped up when searching an old personal hard drive...  An automated search for meteor photos.

Well, I was nearly there.  After spending a few nights with ImageMagick and some meteor photos, I built a basic recipe to find meteor strikes in night sky photos.

Hey, I thought...  I have a PINE64 on order.  Wouldn't that be cool to make one of these tiny ARM based computers comb through photos for meteors?  Ohhh...  With a little thought this could be easily scalable.  What about controlling my camera with one of these PINE64 computers?  Maybe a loosely coupled cluster of these $15 computers to search these photos in different ways?

I needed a control language for this; something interpreted and not terribly complex.  It only needs to be able to run shell commands, copy files and talk to MySQL.  Lua had my vote until I tried MySQL.  After two hours of trying to make it work on my Windows 7 computer, the necessity for a different language became apparent.  Sorry Lua.

A buddy of mine at work likes Python.  My daughter learned a little Python at college last year.  Python is a language specifically being ported to the Pine64.  The memory footprint of Python is larger than that of Lua but should work fine in the constrained environment of the Pine64.  MySQL Connector was easy to install and setup.  After a running a few little trial scripts, I was convinced Python would be my control language for this little project.

So, over the last week or so, this old dog has learned a few new tricks; and he is enjoying it!

First Dark-Sky Photo! May have a new Hobby!

After reading a little bit following a few frustrating attempts at dark-sky photography, I think I might just have a new hobby!

Actually came out better than I thought it would.  Orion, Gemini, Cancer and Canis Major are all obvious.  The star cluster M44 is easy to see and with a little squinting, M67 is there. 

Some fine tuning is still necessary - the focus is still not as sharp as I would like and less trees would be nice.  Our backyard is an OK spot for now.  Getting the focus properly set and fine tuning a few other things just might let me see some decent objects down to 7+ magnitude or maybe even more dim! 

Photo date/time: 2016-02-12 at about 2248 Central Time. 
Camera: Canon Rebel T3
Lens: EF-S18-55mm f3.5-5.6 IS II
Focal Length: 18mm
ISO: 1600
Aperture: 4.0
Exposure: 25 seconds
Tripod: Super cheap (and I mean CHEAP) Targus from Walmart.

What is my goal?  I want to see meteors!!! 

Astrophotography - might just be a cool little hobby!

Adventures with a free PC and Linux

Many people do it...  In many parts of the world, dumpster diving is a profitable undertaking.  As a matter of fact, I knew someone in Los Angeles years ago who made some nice cash by simply checking out local dumpsters, cleaning her finds and selling them on Craig's List and E-bay.  Most of her finds were clothes, fashion items and artsy collectibles.  Me???  Back in my college days I could regularly be found snooping around dumpsters for electronics items.  Some of my best finds from years ago include an oscilloscope, several televisions and a shortwave radio receiver.

Well, even now when I see something interesting in the garbage, I simply can't help myself.  A few weeks ago my wife and I were driving to the local grocery store.  In the parking lot of the grocery store is the local community dumpster where people occasionally toss their unneeded electronic items.  The local waste disposal company hands that stuff off to an electronics recycling company...  Unless someone gets it first.  On that rainy cold January day I grabbed a soaked Dell Dimension E310, Dell monitor and an Epson printer.

"Sure, honey!  I bet I can get that stuff to work!"   She just looked at me sideways, smirked and nodded her head.

After a few weeks of drying, I cleaned everything up, applied electrical power and SHAZAM - up popped a Windows XP logo.  She Works!!!

Sort-of...  The installation of XP was messed up; likely due to malware.  It was SLOW, booted erratically and generally did not behave like a healthy computer.  What to do...  My wife wanted a computer to browse the internet and handle email; basically something to replace her laptop until we can afford a replacement laptop.  Me; well, I would like a separate computer to let me brush up on C.

This computer fit the bill.  It only has an 80GB hard drive, 512 MB RAM with an Intel Pentium 4 processor running at 2.8 GHz, but that should be able to handle these undemanding tasks, right?  Well...  It depends.

I didn't want to waste time repairing and/or reinstalling Windows XP, so I decided to install Linux. My first two choices were Ubuntu and Debian.  This wasn't because they were especially fast or known for performing well on older, under powered machines.  These were selected because they were mainstream distributions and...  I already had installation ISOs on my work computer from a previous project.

First up...  Ubuntu.

I burnt the Ubuntu 14.04.03 installation ISO to a flash drive and installed it flawlessly, albeit slowly to the Dell.  After install, the little TP-Link WiFi USB dongel worked easily.  Basically, the install worked but was SLOOOWWWW.  I was not used to the Ubuntu desktop and honestly is was not intuitive for me to navigate.  Where is the control panel?  The settings?  Fading windows and sliding controls aren't necessary here.  How the hell do I shut them off???

There was no desire in my blood to google every little question I might have about this installation.

So, not happy with the interface and performance provided by the default Ubuntu installation, I decided to try Debian Jessie (8.3.0).

Quick lesson here - when using the Universal USB Installer program from pendrivelinux.com, remember to format the flash drive before copying a new installation ISO over a previously copied installation ISO.  Not doing so caused all sorts of problems.  Debian wouldn't install and regularly complained about a missing kernal image or problems installing GRUB.  Subsequently trying the Ubuntu install caused both installs to get tangled; I saw some Debian install options on Ubuntu reinstall attempts!

At any rate, after finally, successfully installing Debian with the XFCE desktop,  all was almost good.   Performance was decent and XFCE navigation was intuitive and complete.  Supposedly my little TP-Link USB dongel should have worked but didn't.  So, after a little research I downloaded, built and installed a new driver and...  drum roll please...  After spending only $15 for power and VGA cables and a lazy Sunday afternoon, my wife has a temporary computer and I have something to mess around with and brush up on my C... with operational TP-Link WiFi.

Hurray for dumpster diving.!!!

Photography - Just a Little Hobby

Ham radio, shortwave radio, electronics, motorcycles...  These are all things that have faded from my life over the last ten years or so.  Occasionally this fact weighs heavily on my little inner kid; he just doesn't understand how avocations and interests in my life tend to be cyclical.  In the mid to late 80's I was active in amateur radio and electronics; then again in the late 90's and once again in the mid 2000's.

In the late 2000's motorcycles and motorcycle repair were very important activities.  One might say they were vital activities in my odd little world back then.  Not only did I nearly completely restore a vintage Suzuki VX800 but I rode across the county solo, not once but twice.  Memories of my motorcycle past are a bit melancholy at times.

BUUUUTTTT....  An old interest is rising again and I like it; photography.

Specifically, I enjoy making landscape and agricultural photos.  There is just something fulfilling about recording a certain moment in time.  When the moment and light and camera settings are just right and the shutter snaps, honestly, I get goosebumps.

Standby - new photo website coming soon.  :-)

The 4400 - An Old Review by a Crazy Old programmer

Some couples go out at night after work for a few drinks.  Some go out dancing.  Some like plays or theater.  Others enjoy participating in sports.  Some like to go mudding in big 4x4 pickups.  Others enjoy riding together down quiet stretches of highway on two wheels; we certainly shared a few blissful motorcycle miles.

Unfortunately fate, the bitter harsh bitch that she can be, narrowed our pool of potential shared activities significantly.  That, however, just means a life adjustment.  Rather than go out of the house to participate in some activity; we stay indoors for the most part.   And, what do we frequently do???  Binge watch television shows.

Last month my wife found this show, The 4400 on Netflix and we decided to watch it.  So, one night after the next, weeks on end we watched The 4400 from beginning to end.  And the review???

Well, it's no Breaking Bad, however it was worthy of binge watching.  The 4400 series begins with 4400 abductees being returned to Earth all at once on the shore of a Washington State lake, out of a giant ball of light.  Over the course of the next 43 episodes we watch as some of these 4400 people re-integrate into society.  Consider two important facts about these folks... 1) They didn't age a day from when they were abducted;  2) They all have special 'abilities'.  So an abductee from 1977 wouldn't have aged.  If the person was 25 years old in 1977, they were 25 years old when they returned.  And...  the abilities...  One of the main characters can heal, one has telekinesis, one can take away 'abilities'...  The list goes on...

Add in a shake of government conspiracy, societal unrest, little science fiction, little tiny amount of mystery and romance and there it is...  The 4400.  Really, to me this program appears to be a thinly veiled mish-mash of Heros with The X-Files.  Even though The 4400 was aired before Heros, the former seems more stiff and less engaging.  For me, Heros was more entertaining, engaging and enjoyable; it even seemed more original.

So, if you like Heroes or The X-Files, you just might like watching The 4400.
