HomePod Overview and WWDC17 Updates

Today Apple kicked off its annual 3 day developer conference with a couple nice announcements: an update to the iMac Pro, a peer to peer payment system similar to venmo, and HomePod a rival to Amazon Echo and Google Home.

Let’s first talk about the new iMac updates. It looks like Apple is all in on VR (virtual reality) and is building current and future hardware updates tailored to supporting VR graphics.

This fall Apple will be releasing a new version of it’s OS called: “High Sierra” some of the features include better facial recognition in the Photos app, some new filters as well and will be synchronized across devices.

Apple is also porting over it’s Apple File System to macOS, which isn’t a huge change but has some improvement to duplicating files and a higher quality video compression.

From a hardware standpoint Tim Cook was quoted saying: “That iMac Pro really is bad ass”

In iOS 11 you will now be able to make peer to peer payments through iMessage. Very similar to how you would with Venmo or Square Cash. There will also be support for multi room audio and a feature to help silence notifications while you are driving.

Now on to the HomePod…

This new device which will compete with Amazon and Google will come in two colors: white and black, and starts at $349 retail. While the HomePod looks like a microphone itself, it features 6 microphones in order to pick up on every command.

Twitter users have been comparing it to a ball of yarn…

Wow, the #HomePod comes in so many colours! #wwdc2017 pic.twitter.com/Bf4slYNlEC

My Take: While the HomePod is cool, Amazon and Google already have a leg up in the race. Apple will need to catch up to gain market share and hopefully have great integration with Siri across all devices.

Spectrum vs AT&T Uverse

As a long time bright house customer I have been satisfied with their service and have enjoyed (for the most part) their internet speeds. We have had some hiccups and brighthouse has been good about coming out multiple times to address the issues however, my interest lies in reliability as I often work from home and need consistency.

I recently discovered that a fiber box was installed directly in my front lawn with service from ATT. I’ve heard some good things about fiber and the 1Gbps (940Mbps) internet speed and the distance to the box to my house also seems appealing.

I currently leverage brighthouse (now spectrum) with their lighting internet 200 bundle with basic tv for 4 tvs. This delivered (on a good day) 200Mbps internet. Out of curiosity I went ahead and checked my speeds as I was writing this blog and I am currently only getting 113 down and 15 up. So as I’m used to with bright house, I’m paying for more than what I am getting. There is a good python script speed checker that you could install onto a raspberry pi and have it routinely check speeds for you on github. It also tweets out the speeds if they are lower than what you are paying for. I may try that once I finish this blog.

I have been paying about $199 a month for spectrum after all taxes and service fees are included. The actual cost of the internet is $107 which is what I am really concerned with. I don’t watch much TV in my free time, so paying another $100 for TV service on top of internet is a bit silly to me. So I thought it may be beneficial to post a spectrum vs at&t post and see if I can reduce or enhance my services.

At first glance going to the ATT site is a bit confusing as they have multiple internet, mobile solutions, and a mixture of directv and uverse tv offerings. It took me a bit to narrow down which services even being a bit tech savvy and somewhat educated on their latest offerings. I finally found what I needed by using a services locator tool where I plugged in my home address and it displayed what was available to me.

DirectTV seemed to be pushed as their go to TV solution, I have however used that service in the past and enjoyed the programming but the service did not fair well during our summer storms in Florida. I opted to go with the uverse programming. I also noticed that the digital uverse tv service also removed a data cap on the fiber internet. As I mentioned before the TV service isn’t a big deal to me, but removing the internet cap makes up for it.

I finally found the internet speeds, and it looks like 1Gbps was available as I was hoping it was. The cost by itself was only $90 ? Wow! If i compare spectrum vs att, we are looking at brighthouse charging $107 for 200Mbps and ATT charging $90 for 1000Mbps. Wow that’s 5 times more speed for $17 cheaper a month. That’s a savings of $204 a year, on just internet.

At this point I was pretty sold but was convinced that there were some hidden charges or fees I wasn’t seeing. I went ahead and started to checkout using their eCommerce page, found a TV and internet package for four TV’s and the monthly cost was only $130… they waived all of the activation fees, and the setup and installation fees.

So I’m now only paying $130 a month for the same or better (yet to be determined) TV service, and 5 times faster internet. That’s a savings of $828 a year! I get the services hooked up on Thursday and will do a deeper dive on what I like and don’t like, but at this point it appears to be a no brainer.

The only downside I noticed was that these prices were only for 24 months. After the 24 months the prices raise. I may at that point do another comparison of att vs spectrum again and see if I am in fact getting the better deal, but until then ATT wins my business for now.

EMC Unity Makes Flash Storage Simple

If you were looking for the announcement of “VNX 3” at EMC World you may be disappointed… but you shouldn’t be. Instead what you will find is an all new, built from the flash up, midrange storage device. EMC Unity was built with four key and very clear goals: simple, all flash, rich data services, and affordability.

Unity provides the most complete set of data services on the market from day 1, including all of the features necessary for deep VMware integration, complete Microsoft integration, and access to all of the latest data capabilities: VASA, vVOL’s, SMB3, NFS, CIFS, and more. With all of these advanced features and functions it is tough to keep everything simple, but EMC has knocked it out of the park with a very easy to use HTML5 interface. NO MORE JAVA !!! From one simple interface you can create protection schedules for file, block, and vVOLs using unified replication and snapshots.

Sure the simple interface is just my opinion, but EMC also took it a step further and ran some third parties tests with Mad Pow. They compared the interface to a some others in the market and were blown away.

“EMC is setting the standard for storage simplicity” – Mad Pow

EMC Unity was designed for all flash but also has a hybrid option as well and the ability to tier to the cloud. With the all flash configurations you can get up to 80TB in a single 2U shelf. For the ultimate in options you can also have a virtualized Unity appliance in the data center to serve as replication target or to deploy for dev test scenarios.

When I say that EMC Unity is designed for flash, the above image demonstrates the key differences in legacy hybrid arrays trying to act as an all flash array. Typically the NVRAM in legacy hybrid arrays is small and fills up quickly. With Unity you can utilize the full system cache, that also scales as you add more flash drives. Eliminating the NVRAM bottleneck.

With the all new storage architecture, some new space efficient features are included. No Storage left behind, meaning no reserved space for snapshots and free space is returned back to the pool when snapshots are removed or deleted. Built in copy data services allow fast and space efficient, pointer based snapshots. Replication is just as efficient, only sending data based on snapshot deltas.

The best part about all of these features I have described is the simplicity. No longer do you need an entire team to manage storage. You can now do it with your eyes closed… well you might have to peak to see the screen 😉

EMC World Biohacks for Hangovers

As we get ready for EMC World 2016 we are already anticipating long days of sessions and networking as well as long nights of social events and just vegas in general. I was recently listening to a Tim Ferriss podcast on he survived the SXSW conference and it appeared very relevant to a week at EMC World.

Let’s get into it! If you have ever “time traveled” while drinking you probably experienced a lack of vasopressin. Vassopressin is a hormone that is related to short term memory and is suppressed when ethanol (alcohol) is introduced into the body. In order to reduce the effects of this here are 4 things you can do during EMC world to help reduce the after effects of late night drinking:

Water – your best rule of thumb is to drink at least one glass of water per alcoholic drink. Maintaining hydration is your biggest key to waking up without a headache.
Guacamole – Drinking depletes the body of necessary potassium, and avocados are rich with it. Avocados are also full of fiber, healthy fats, and B6 vitamins to help get your muscle function back on track and keep sodium at bay.
Clean Drinks – You are what you eat and you feel what you drink 😉 Tim recommends drinking a “NorCal Margarita” which is a lightweight way to drink a margarita without sacrificing the alcohol. A typical margarita packs in 250-300 calories per drink, along with sugars, high fructose corn syrup, and a ton of artificial ingredients in the margarita mix. A NorCal margarita has only 3 ingredients: tequila, club soda, and lime.
- The tequila being used is fermented agave juice, both gluten and starch free
- The lime juice blunts the insulin response of alcohol
- The carbon dioxide bubbles in the club soda help to deliver the ethanol to your blood stream quicker, thus you drink less with the same effect
Burnt Toast – If you are really feeling rough, burn some toast in the morning and scrape the burnt toast into some yogurt. The carbon from the burnt toast will help to absorb alcohol and other toxins in your body to help you get back on your feet.

Sleep also helps, so make sure you “nap” when you can. I hope those tips help you experience EMC World to its fullest, and if you have any other tips or suggestions feel free to comment below and make sure to share this article with your co-workers.

VxRack Nodes

I’ve been asked quite a bit lately on VxRack node types and options so I wanted to go over what is available and some of the options. First lets start off with the VxRack 1000 Flex options. At a high level there are 3 vxrack node types that can be configured in a VxRack solution; Dense Compute, Dense Storage, and a Storage only node. Each of these nodes have a couple variations in order to properly size and accommodate various workloads.

VxRack Node: Dense Compute

Winning Powerball with Big Data

If you are looking for the magic formula to win the lottery you have come to the wrong place. However today we will have some fun with some of the Powerball’s previous winning numbers so we can better decide on how we want to make our picks for the upcoming drawing.

Before we get started lets take a step back and get a basic overview/understanding of how powerball works. Drawings are held Wednesday and Saturday evenings at 10:59 p.m. Eastern Time. The game uses a 5/69 (white balls) + 1/26 (Powerballs) matrix from which winning numbers are chosen. Each play costs $2, or $3 with the Power Play option.

I also want to note that there was a format change on October 4, 2015 which we will want to keep in mind when calculating powerball winning historics. The white-ball pool increased from 59 to 69 while the Powerball pool decreased from 35 to 26. The new setup was designed to help create more winners and also more rollovers. Which is why we are now looking at a record estimated $1.3 billion dollar prize.

So the more and more I’ve researched different ways to predict powerball numbers using big data I was able to come up with two important facts that will save you some time and heart ache.

The Powerball numbers are drawn randomly
As humans we pick numbers non-randomly

About 70% to 80% of powerball purchases are computer picks and about 70% to 80% of winners are from computer picks. [source] So if I was going to play I would buy mostly randomly generated tickets based off of a computer; but possibly play one based off of historical data. I built this excel spreadsheet [download] with the data from powerball.com on all historical winning numbers back to 1997. So download and enjoy (if you win I would expect a small donation 😉 )

In the excel spreadsheet you notice I have setup 3 tabs. The first tab is a random number generator for each of the white balls and the powerball in the event you don’t trust the powerball computer picks.

The second tab is a table of all of the past winning numbers in the order they were picked. This would be a good data source if you wanted to utilize some data processing to calculate odds and trends.

The third tab is the frequency of each winning number called and broken down by white balls and power balls. Here are some screenshots:

As I started crunching the numbers and odds I realized that the overall odds of random are already so high that if I want to actually play the powerball my best bet is to just let the computer pick the numbers. The moral of this unfulfilled blog entry is that we pick numbers non randomly and the powerball is picked at random. So if you want to win, make sure you do it randomly 😉

Let me know your thoughts on the excel data and how else we could make the numbers more useful in the comments section below.

Could not find a server that was suitable Halo 5

Connection Lost you have been disconnected from the local network. Returning you to the main menu. Could not find a server that was suitable for all members of your fireteam.

It’s not often I get to sit down and enjoy some online gaming these days. But when I do, I expect a pretty simple end user experience and shortest time to actually play a game. My most recent Xbox One game purchase was Halo 5 Guardians and I have had some issues connecting every time with what seems to be a generic error message: Could not find a server that was suitable for all members of your fireteam.

Could not find a server that was suitable for all members of your fireteam. Halo 5

I found an Xbox support article called: Troubleshoot Halo 5: Guardians multiplayer issues which gives some suggestions for basic troubleshooting but has still been unable to correct an ongoing problem keeping me from playing. There are also a pages on halowaypoint, reddit, and gamefaqs that offers some user suggested troubleshooting.

Here is what I have tried and what has seemed to work:

Hard Reboot (pull the power plug) of Xbox One: Has worked once, but not consistently.

Hard Reboot of Router: Has also worked once, but I like to keep my xbox in the DMZ and the hard reboot assigned another IP to the Xbox so I had to go back and reconfigure. Long story short, that has only worked once as well.

The best advice I have so far is: Unplug your Xbox, then unplug your router, breathe deeply for a minute, turn back on your router, then turn back on your Xbox. This has worked the most consistently for me so far but I’m not happy with this as a solution. I can play other games fine when this is a problem so any other advice or troubleshooting techniques would be greatly appreciated.

Google Trends for Monday and the days of the week

As I’ve been building out the framework for “Attack the Week” I started to become curious as to which days of the week were most searched for, commented about, or even tweeted about. Since I’m building a framework for Mondays, I was curious as to which days people are actually interested in. My initial thoughts were that Fridays were going to win in a land slide, but it turns out that its not quite the case.

My initial data search lands me at Google Trends, where I searched for the 5 days of the week and their interest over time. While this isn’t the best way to determine how popular a specific day of the week is, it does give some direction and a good idea of what people are searching for when it comes to the days of the week.

So a typical business work week (Mon-Fri) is about as I imagined it. We have Friday on top with the most searches, Monday in second, and a close tie between Wednesday and Thursday; followed up by Tuesday with the least interest according to Google Trends. Now for this experiment I’m not as worried about the weekend, but while we are here and for curiosity sake lets dive into some weekend stats compared to Friday.

So according to Google, Sunday has the most search interest, followed by Saturday, and then Friday. So while we can make several assumptions as to why this is the case, I’m going to simply assume that weekends are more popular than weekdays.

Now onto tweets per day… I was limited to only three keywords for my search on Topsy, so I decided to go with Monday (obviously) and the most popular work day: Friday. Now for the third I was on the fence but decided to go with the most popular day of the week Sunday. Not only did it have the most interest on Google Trends, but it also precedes Monday so I could possibly notice any overlap.

In this one month sample of tweets, I noticed that Friday has about a million more mentions than Sunday and Monday. I also noticed that the tweets usually came a day or two before the actual day being talked about. Which also makes sense, people will tend to tweet about anticipation or the lack there of versus “Today is Friday”. I could dive down a bit more and do a sentiment analysis on the days, but this is enough data to satisfy my curiosity for today. What other tools could I use to lookup similar data to this ?

Attack the Week

Well today is Monday and I thought it would be a good idea to try something new. I’ve been reading the Tim Ferriss classic: “The Four Hour Work Week” and have looked at some normal everyday actions with a new set of eyes. Mostly in an effort to become more effective with my time, I was thinking this morning of a quote I like: “Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” Usually when I tackle a large task this quote always runs through my head. So I decided to see how I can apply this quote and my quest for effectiveness to Mondays. As a result, today “Attack the Week” is born.

Most of us view the work week as a set of five equally busy days of business. However we tend to like Fridays better as they are closer to a non working weekend in a typical 40 hour work week. We also usually have the same routine for each of these five days, and chip away at projects or processes the same everyday. Well today lets look at Monday’s in a new light and plan to attack the week vs our typical “case of the mondays”

I will be working on a framework for Mondays rolling forward, but today I just wanted to share my new motto for Mondays and #AttackTheWeek a different way. If you have any ideas on how you approach the week, comment below and I may put them into my new framework. Happy Monday !

***Update: I’ve launched www.AttackTheWeek.com to start storing my ideas, make sure to subscribe if interested!

Windows 10 IoT Raspberry Pi 2 Setup Tutorial

Windows 10 IoT Core Raspberry Pi 2 RobSteele

After researching tons of use cases and features of IoT devices and machine learning techniques, I decided to go ahead and purchase my first Raspberry Pi 2. I primarily want to explore setting up sensors and streaming that sensor data to various cloud providers. I’ve also looked at a couple projects dealing with some mesh networking that looked interesting, but for this project we will be setting up Windows 10 IoT Core on the Raspberry Pi.

So to get started with Windows 10 IoT core you will need either a Raspberry Pi 2 or MinnowBoard Max. We will obviously be using a Raspberry Pi 2 in this tutorial. If you haven’t already purchased a RPi2 I recommend purchasing a kit with power supply. Luckily I had a micro USB cable available and an AC adapter. You will need at least 600mA at 5V to be up and running. You will also need a microSD card. I went with a 16GB card so we will have plenty of space, but an 8GB card should be enough for a minimal setup.

Download Windows 10 IoT core

Once you have your hardware in place, download the setup tools from http://ms-iot.github.io/content/en-US/Downloads.htm . You will see “Windows 10 IoT core for Raspberry Pi 2” go ahead and download the ISO file called “IOT Core RPi.ISO” You can mount the ISO or open it with an archiver software such as WinRAR. Inside the ISO is an MSI file to install the components. Go ahead and install the package. Note: There are some tools in this package to make this much easier if you are using Windows 10 already for your operating system, but I am not so we will be using some 3rd party tools instead of the native Microsoft Tools.

Now that you have the software installed, you will see Microsoft IoT in your start menu or program files, with 2 executables. One is called WindowsIoTCoreWatcher which is a lightweight program for viewing all of your IoT running machines. The other is called WindowsIoTImageHelper which will help you flash your microSD card.

From what I have read these applications are supposed to only work or are only supported when using the Windows 10 OS. I’m currently using Windows 7 and both seem to launch fine. I’m going to go ahead and try using the flash utility but will also list the steps for an alternative way to flash the microSD card.

Flashing the microSD card with Windows IoT Core Image Helper

So if you see the screenshot above it looks like the microSD card is detected, but only showing 7Mb. Even though this is a 16GB card, I’m going to push forward anyways and see what happens. This utility is about as easy as it gets; first select your microSD card and then select the image file. The image file is located here: C:\Program Files (x86)\Microsoft IoT\FFU\RaspberryPi2\flash.ffu (unless you chose to install into a different path) . Once you have the correct settings, simply click “Flash” and you will see a command prompt appear with the status of the flash.

After the microSD card is flashed, you can now insert the microSD card into you Raspberry Pi 2 and boot.

Windows 10 IoT Configuration

Once the RPi2 is booted with the new image, you will see the windows 10 logo and a typical boot screen. Once the OS is finished booting you will have an option for language. I simply selected English and that was all you needed for configuration. Now since I had my ethernet cable plugged into the device is picked up an IP address and was given a device name of “minwinpc” by default.

Windows10 IoT Core Raspberry Pi 2 Screenshot

Once the device is up and running you have two tabs, one is a device info tab (shown above) and the other is a tutorials tab. You will also notice that if you launch the WindowsIoTCoreWatcher on the same network you can now see your device.

If you right click you have four options available: Copy Mac Address, Copy IP Address, Web Browser Here, and Open Network Share. Pretty simple ! You are now able to develop on your windows 10 iot raspberry pi 2 device ! If you have any questions or thoughts, please use the comments below.
