Mac Mini, USB 3.0, Bluetooth and WiFi

by Codewiz51 8. March 2015 08:27

I recently purchased a 7 port Ankar powered USB Hub.  All was fine with my original layout, but yesterday, I decide to layout my devices to reduce clutter.  Just after completing the rearrangement of devices on my desktop, I started having trouble with my WiFi dropping and then not being able to reconnect.  Shortly thereafter, my Apple Magic Mouse began disconnecting.

I dutifully shutdown my Mini, disconnected all the devices, ran hardware diagnostics, booted in single user mode, cleared the SMC, etc.  Could not find any problems.  Mac booted properly, mouse worked properly, WiFi connected.  What the heck was going on?  I changed out my Crucial memory with the original Apple memory.  The Mac with no devices was working properly.

I started reattaching devices, first connecting the Ankar hub, then external drives, Apple Superdrive, etc.  Boom!  WiFi went flakey.  While turning off the WiFi, my Magic Mouse disconnected.  Rebooting gave me a completely blank screen with only a mouse cursor.  Things appeared to be going down hill quickly and I was not happy, because I had planned to put 20 or 30 miles on my bike in the sunshine.

So I stripped down the Mini again.  Turned off the magic mouse.  Plugged in a USB mouse.  Plugged in a wired network cable.  Booted.  Managed to log in.  Turned off WiFi on the Mini.  Turned on the Magic Mouse.  It connected properly.  Unplugged the USB Mouse.  Started plugging in devices.  Everything continued to work.  Left the WiFi off.  Rebooted.  The Mini came up and I could log on just fine with the wired network cable.  Decided not to tempt fate and left the WiFi turned off.

My (incomplete and unsubstantiated) conclusion was that rearranging the Mini, with all the USB devices sitting close by on the Ankar hub was causing interference with all of the wireless devices I was using.  Since the Mini is not really portable, I decided to leave the network cable plugged in and turn off the WiFi.  However, I'm not super happy about this, because the Mac no longer syncs with my iPhone over WiFi.

I'll settle in with this setup for a while, until I can figure out what to do with all of my USB devices.

Whither My Home Network?

by Codewiz51 7. November 2014 07:39

I have a small home network that I use for hobbyist programming and R & D on new (to me) technologies.  I lost one of my servers (which also acted as a backup domain controller) a couple of days ago.  There was no real content on the server that I needed to save, and fortunately, the disk drive is OK, it's the motherboard that went out.

I'm debating about continuing to maintain this home network.  It's constantly an issue in terms of maintenance.  If the internal DNS server goes down, my wife gets mad.  If the print server starts acting up, my wife gets mad at me.  I'm working with really old hardware, which could go out at any moment.  You get the picture...

So, I'm debating about just shutting down the home network, removing the two workstations I have from the domain, and going back to being an average hobbyist.  I primarily need access to a SQL Server and an IIS Server.  I have a couple of options.  I can use the services on WinHost as my primary environment. I also have an MSDN account through my company that allows me to set up sophisticated environments for development.  In other words, I have the capability to continue developing, while simplifying my life.

I'll think on this a little more and hopefully get some things implemented over the weekend.

Setting a StaticIP on Azure Server Returns an Error

by Codewiz51 5. October 2014 15:24

If you ever get the error: "Update-AzureVM : BadRequest: The value for parameter 'SubnetNames' is null or empty.", do not fret.  The fix is simple.  The VM that you are trying to assign a static IP does not exist in the subnet you are trying to assign it too.  I ended up deleting and recreating the server, making sure I used the "Gallery" and not the "Quick" creation option.  Then, ensure you create the VM in your private network.



Head First HTML5 Programming

by Codewiz51 6. July 2014 08:36

I've been working my way (slogging) through Head First HTML5 Programming: Building Web Apps with JavaScript [Kindle Edition].  The book has a quirky feel, with lots of odd pictures and sidebars.  It allows you to work your way through the code and the testing is ingenious, yet thorough.  I found it worthwhile to work my way through the tests, which are generally a "match the word to a blank in a sentence" style.

I generally learn better through books.  I like to read, and generally learn a subject more completely by reading a "getting started" book like Head First HTML 5, followed by the reference documentation for the subject.  I particularly enjoyed the introduction to the Google mapping API, which I have been dancing around for the last year.  The intro was straight forward and provided me with the correct terms for further web searches.

If you've been working in JavaScript and HTML 4 for a while, this book is an excellent kick start.  I highly recommend it.

Happy Independence Day!

by Codewiz51 4. July 2014 07:56

On this day, July 4th, 2014, I would like to thank the thousands of men and women that have given their lives for our liberty.  So many stories of bravery and sacrifice are untold but are appreciated beyond my ability to express.  We can live and breath and pursue happiness in this country thanks to the vision and wisdom of our Founding Fathers, some 238 years ago.  It would do well for all citizens to read and understand the Declaration of Independence and the US Constitution, along with the first ten amendments, known as the Bill of Rights.  I wish all of you well, free to enjoy a safe and happy celebration of our Independence.
