Below is a link to a massive download for an excellent Pre-loaded Test Virtual Machine with SQL server, Visual studio development software and windows server 2016
Resulting extracted VM VHD is about 55Gb
Happy New Year 2018!
Benchmark results from my primary laptop/workstation.
Software used:
Android Development Screen shots Notes, showing my settings, and most especially space costs on my dual OS laptop.
I dual boot into Windows 10 or Ubuntu 16 on my laptop, l find the later faster and more Android sdk development simpler since l have to disable Hyper-V which l need on Windows 10 if l setup my full Android development on it – including emulator for testing.
Note, the complete tools below l chose and use take a lot of space. In my case, 30Gb, so plan accordingly.
Choice of SDK platforms.
My current phone is the LGG5 – running Android 7.0, however l also own an older Nexus 6 [no sim card/wireless plan] which l use for Android development testing running Android 7.1.1 [google nexus phones get the latest android releases frirst, unfortunately at least the nexus 6P not 6 is required for Android Oreo/8] 🙁 , and one of my target platform is Ikechukwu’s older samsung galaxy tablet which runs Android lollipop 5.0.1
I also chose Android MM – Marshmellow 6.0.1 since l have a tester using that version residing in Jos/Lagos on his phone – onijec [click here for his twitter link].
I want to test developing a small birthday countdown app for Ikechukwu, see if this works on multiple Android versions, test and use my google developer account/playstore and non playstore app distribution – before diving into more deep stuff like geo location based apps l am more interested in.
“The Top500 list the 500 fastest computer system being used today. In 1993 the collection was started and has been updated every 6 months since then. The report lists the sites that have the 500 most powerful computer systems installed. The best Linpack benchmark performance achieved is used as a performance measure in ranking the computers. The TOP500 list has been updated twice a year since June 1993.”
“Mflop/s is a rate of execution, millions of floating point operations per second. Whenever this term is used it will refer to 64 bit floating point operations and the operations will be either addition or multiplication.
Gflop/s refers to billions of floating point operations per second and Tflop/s refers to trillions of floating point operations per second.”

Passed my Microsoft Cerfification Exam on first attempt on Tuesday June 2nd! Score: 814
The certificate says l’m now recognized as a MCTS – Microsoft Certified Technology Specialist: SQL Server 2008, Implementation and Maintenance. The exam is the MCTS 70-432. Next goal is the 70-450 which has no study book in print, and the only material l can find so far is the CBT-NUGGETS training video on Exam 70-450 which is very good.
Materials l used to study other than multiple SQL Server instances on my laptop, Virtual PC Windows 2008 Machines with SQL Server 2008 installed – for database replication, mirroring and failover clustering practise!!!
– MCTS Self-Paced Training Kit (Exam 70-432): Microsoft® SQL Server® 2008 – Implementation and Maintenance by Mike Hotek (Very good, in-depth all round material, lab oriented book with real life stories). This seems to be the only main book out there.
– Self Test Software for MCTS 70-432, bought the download version of this excellent practise test program.
– Microsoft Sql Server 2008 Books on line (download the latest update from Microsoft)
– Took the official Microsoft 6231 course at SQLSoft (Beaverton)
– Books on Microsoft SQL Server 2005 exam 70-431

Looking for a NAS, with gigabit interface (l’m done with slow access speeds via usb interface to my internal gigabit network) so as to speed up my rendering server farm file access, and expandable with support for additional sata drives and affordable. Finally settled for the DLINK DNS-321 for $130 and bought just one 1Tb SATA drive that was on sale for $87 – a Samsung 10,000rpm 32Mb buffer drive. As sata drives fall in price and l get more bang for a buck l can add to this unit. I can mirror a drive, but the unit doesnt support ntfs etc – which is fine for me since my shared files on this will be media files, mp3 and rendered jpeg pictures. It has a web interface control and can be accessed remotely via ftp anywhere on the net. This system is built on a GPL / Linux based system, and will format your drive to ext2 format. There might be a hack out there for a more native windows file system support.
Update: 5/14/09. I’m returning this item. The file transfer time to and fro ext2 to my ntfs formatted drives is so so slow, about 10-20x (even by Windows wrong estimates). The gigabit connectivity makes no noticable difference, even when on the same Cisco 5 port Gigabit switch as my server. I’ve ended up overloading my faithful dell sc430 server by “creatively” adding this 1Tb drive to it, the server is designed to support only 2 sata hard drives. See picture below.
