Head to Head Comparison: Fitbit One vs. Fitbit Charge HR

I'm a health-minded person, and I often spend a good portion of my free time on fitness-related pursuits.  Running is one of my favorite hobbies.

I've been a pedometer user for many years.  I used to wear a mechanical pedometer to track my daily activity.

In more recent years, I've moved onto fitness gadgets that keep track of all that for you.  I've had a Fitbit One since March 2013.  I enjoy tracking my daily activity with it and challenging my friends and family regularly via their leaderboard feature.

A few months ago, I set my One aside in favor of a Charge HR.  A lot of my exercise isn't easily read by a pedometer (best for running and walking activities).  I wanted the calories burned based on heart-rate readings.  I tie Fitbit in with MyFitnessPal and wanted accurate calorie data as I track what I eat in pursuit of weight loss goals.

After getting to know both gadgets, I could see definite pros and cons to each device.

  • Fitbit One
    • Pro
      • Inconspicuous
    • Cons
      • Easy to lose
      • Wristband for night wearing is inconvenient
  • Fitbit Charge HR
    • Pro
      • Heart rate data
    • Cons
      • Some people do not like the watch style
      • Skin rashes for some
      • Easy to see you are wearing it

I wanted to compare the accuracy between the two devices.  I was convinced that the Charge HR would give me loads of unearned steps from arm movements.  My experience: that was not the case!

Below is a brief overview of each day.  My activity (normally there'd be plenty of exercise, but I was suffering from a cold and didn't do as much as usual.  I also noted car trips.  I see lots of feedback from others about watching the watch-style Fitbits record steps while driving/riding in a car.

Results/Summary
It's a good reality check that these devices aren't the end-all, be-all for accuracy.  My father-in-law has done similar testing and gotten very different results.  He was finding larger discrepancies (say 2000 steps on a 12000 step day) with the Charge HR reporting more than the One.  

I've got half the week with close ending step counts (one was off by two steps, others off by a few hundred steps for a 3-4% discrepancy).  Those are promising results.

But I've got 3 days with 12-18% discrepancies representing step discrepancies of over 2000 steps.  Considering that's enough to be at least a mile, it adds up.

What does this mean for me?  Not tons.  I still love my Fitbit products and will continue to use them.  I just won't take the data as ironclad fact.  I find it interesting if nothing else.

Difficulting Editing Network Card on vSphere 5.5

I have to confess, I've been "kickin' it old school" and haven't embraced some of the new ways of doing things with my VMware ESXi systems.

I stayed at version 5.0 on vCenter and ESX for awhile.  News of the challenges of the upgrade to 5.1 and the Single Sign On implementation gave me pause and I delayed.

So much so that I skipped 5.1 altogether and upgraded to 5.5 approximately 1 year ago.  (I haven't yet dipped my toe into 6.0.  We have other large scale upgrades and initiatives that haven't allowed me the time to do so.  I hope to investigate it in the coming months.)

One of the other new things I've been avoiding?  The vCenter Web Client.  I was used to being proficient and moving quickly through the vSphere fat client.  Certain features weren't there (hello, Update Manager), and so many things were in different places.

Related to that, I haven't taken my Virtual Machine Hardware versions above 8, so they could all be edited in the fat client.

Okay, with that background out of the way, this weekend I performed a sizeable P2V migration of a SQL server.  And, when the time came, I decided to abandon some of my older ways.  I built the new system as Virtual Machine Hardware version 10, current to my 5.5 infrastructure.

So, after the initial P2V work was done (by running vSphere Converter Standalone), I was working with my new virtual server (uninstalling hardware drivers as appropriate).  I noticed I had an Intel E1000 network adapter.  My standard is to use the VMXNET 3 adapter.  This allows my virtual systems to communicate amongst themselves at 10Gbps.

OK well this is easy enough to fix.  (Or is it?)  I powered down the virtual server for good measure, and attempted to Edit Settings.




Well, that was silly of me.  I knew that was coming.  OK time to sign into the vCenter Web Client to make the changes.

But wait!  Even with the VM powered off, I could not edit the adapter type--it was grayed out and unchangable.  What was going on?  I began to panic.




I attempted to add a second Network Adapter.  Again, I wound up with an E1000 I could not edit.  My panic level rose.

The trick, and how to accomplish this task, is to DELETE ALL NETWORK ADAPTERS.  Once there are none on the system, and you add one--then you can edit the type.  At that point, I selected my desired VMXNET 3 and was on my way.

Macbook Pro: Moving Mavericks to Yosemite, iPhotos to Photos, iCloud Photo Stream, and a Crushed Internet Connection

At home, I absolutely love my Macbook Pro Retina 15" that I got in late 2014.  I made the switch from Windows to OS X in late 2012 first with a Mac Mini.  While it was a fantastic computer, I decided to switch and I love having the laptop.

I held off on moving to Yosemite for a bit for two major reasons.  Yosemite was having some major networking issues that I knew would be crippling for me using home Wifi.  There were tons of purported fixes that didn't really address the issue.  It sounds like the true fix will be coming in 10.10.4 when Apple abandons their new discoveryd process.  (More on that here: http://fortune.com/2015/05/27/apple-mac-bug/ and countless other places).

The other big stumbling block was the iPhoto to Photos move.  My primary use for my home computer is organization of an extensive digital photo collection.  It is one of my favorite hobbies.  Over many years, I have scanned all of the print photos in my family that I could fine (that number is roughly 4,000).  Throw in a plethora of digital pictures, and duplicates as I preserve originals for edited and improved versions, and today I have over 28,000 pictures!  In iPhoto, they are meticulously organized with correct dates, faces and keywords.  With a few quick clicks or searches, I can put my hands on any photo.  They scroll across my screen daily as my screensaver to be enjoyed.  They are not relegated to a dark box in the corner of a closet.

One of the added bonuses of doing this in the Apple ecosystem was having this complete photo access on my iPhone and iPad.  I have both devices with 64GB of storage, and that was ample space to synchronize my photos.  Events and Faces also synchronized for easy access on those devices as well.  That required me to plug in and synchronize with iTunes regularly, but in doing so, my photos were always at my fingertips.

So, now we have Photos and the iCloud Photo Stream.  By using this software and this ecosystem, now, all my photos will automatically synchronize to all devices with no efforts required by me.  Great, right?  Yes, but it's not that simple.

iCloud gives users 5GB by default.  Before even messing with iCloud Photo Stream, I was paying for 20GB per year.  That was enough space to back up my iPhone and iPad as I needed just over 5GB.  I want to say the current rates for that were somewhere in the neighborhood of $10-20/year.

But now I'm looking at 28k photos!  Yikes.  When I enabled iCloud Photo Stream, it let me know that 200GB would be enough space.  They charge $3.99/mo for that.  I decided that full, no effort access to my photos was worth that and upgraded.

But now what?  My MBP needs to upload all these pictures!  And, here we go...

I have a great Internet connection.  I love Wide Open West and we pay for 50Mbps down with 5Mbps up.  But, Photos just began to push all of my pictures up.  It consumed the 5Mbps upload rate.  And brought my whole household's Internet to a crawl in the process.

It is painfully short sighted of Apple to not give more control on the upload process.  The only control you have is whether or not you keep high quality original resolution on your local device, and an option to pause uploads for a day.

Researching the matter quickly let me know I was not alone.  Many people with similarly large photo collections and similarly crushed Internet connections.  Thankfully I have found a decent solution here: https://discussions.apple.com/thread/6992427?start=90&tstart=0

A post from user 'mayall' on page 7 highlights the fix.  By using an Apple Developer tool known as the Network Link Conditioner, you can control your bandwidth usage.

Sign into http://developer.apple.com with your Apple ID.  You'll need to accept a few license agreements and whatnot.  Then make your way to downloads and get the latest Xcode developer toolset as a DMG download (v 6.3.2 as of this writing on 6/4/2015).

Once you have the Network Link Conditioner installed, it is an option in your System Preferences.  Use the Manage Profiles button in the lower right.  Add a Custom Profile, a name that suits you, and configure the downlink and uplink bandwidth in Mbps.  With my 50/5 Internet connection, I have configured a 20/2 profile.  I am now running this way.  This means my MBP will limit its Internet usage to 20Mbps down and 2Mbps up.  That is leaving 30Mbps down and 3Mbps up for all the other devices in my home, so everyone else can happily use the Internet.

It's been about 5 days so far.  My Internet connection is working well and the photos are uploading.  Out of 28k photos, 18k have gone up so far with 10k to go.

P.S. I am also looking at Google Photos and wondering if I'll need to keep paying for iCloud space.  In the meantime, I will upload them all and decide which one I like best.

How to Pin Windows Update to Start Menu on Windows Server 2012 R2

So, we've all heard the big stink when Microsoft did away with the Start button and menu and the Metro interface.  I know that Windows 10 is moving back towards the tried-and-true way that we expect.

I have been leaving my 2012 R2 servers default.  I don't find the interface too bad.  I just take a moment to pin a few key items to my Taskbar or my Start Menu and it works for me.

Most of these are pretty easy to do.  I hit the Start button, then use the magnifying glass to search for what I want.  I can then right click it and Pin to Start or Pin to Taskbar.  I do this for things like Run, Command Prompt, and Computer Management.  Also any applications on the server that I would access regularly.

One that stumped me, however, is Windows Update.  When I search on it, I can't right click and get a menu.  Now what?

I found an article on using PowerShell to pin items to the Start menu in Windows 8.  https://gallery.technet.microsoft.com/scriptcenter/Script-to-pin-items-to-51be533c  I thought I was onto something.  But Windows Update is a subset of Control Panel.  So I couldn't figure out how to make the script work.  

My approach is painfully simple, but I stumbled across it myself and my GoogleFu didn't lead me to it.  So I blog it here in the hopes that it will help someone else.

Click the Start button

Search for Windows Update

Click Windows Update.  It will open.

In your box's navigation, it says Control Panel | System and Security | Windows Update.  Click System and Security to move up a level.

Find Windows Update as the 4th main heading.  Click and drag it to your desktop.  When you release, you now have a "Windows Update - Shortcut" shortcut.

Take a moment to rename it to Windows Update.

Right click your shortcut.  Voila, the Pin to Start option is there.

Pin and enjoy your day.
