Windows Azure management easier with Mesosphere's Data Center Operating System (DCOS)

Mesosphere Datacenter system is a new OS that spans all of the machines in the data-center/cloud. Applications, services and data can be deployed - highly scalable, and elastic.  Recently Microsoft is teaming with Mesosphere (it is rumored to be bought out by MSFT) to get added value from Microsoft Azure using Mesosphere Meso DCOS by porting Apache Meso for Windows Servers and at the same time catering to Linux. 

You can run Meso DCOS on Microsoft Azure. It is free on Microsoft Azure (https://mesosphere.com/azure) but requires a bit of information about yourself at this link (https://mesosphere.com/azure). You can also sign-up for early access at the same link.

It will be available soon for Google Cloud Platform and it is already available on Amazon Web Services with the free community edition. Get started free on Amazon here.

Apache Meso (Open source) is not the same as Mesosphere Meso but watch this well rounded video on Apache Mesos by Benjamin Hindman to get a feeling for working with DCOS: "Building and Running Distributed Systems using Apache Mesos

Install Firefox for Windows 10

You may ask what about Microsoft Edge. I found it was near impossible to work with my blogs using the Microsoft Edge. Simply put, I could get the images to the interactive page on the blogger but it would not bring the image to the blog. Sometimes the image all of a sudden disappears. Sometimes Copy from Notepad and paste to Blogger does not work (Ctrl C, Ctrl V would work).

As it could not address my immediate need I downloaded Mozilla Firefox for Windows 10 from here:

It worked as required for my blogging. I am sure Microsoft Edge may be better in many ways. For example it could open a PDF file in the browser, etc.
Here are some screen shots of Mozilla.

Download and install were effortless

 I will check out other features in due course.

Here is the version information: 

Upgrading Windows 8.1 to Windows 10- Part 3: Wi-Fi issues solved

I finally made progress connecting the Arris 1670 A router on leased from Oceanic Time Warner to access the Internet from Windows 10 on my Toshiba Satellite S70 series laptop. This post describes the details.

Review these before you read this post:

With Windows 10 installed the Wi-Fi sense works right away and you will see all the Wi-Fi sources nearby including your own.

You could click on any Wi-Fi connection and you can connect/disconnect as shown.


Oceanic Time Warner replaced an existing cable modem (not Wi-Fi enabled) with a Wi-Fi  enabled cable modem(Arris Touchstone DG 1670 Data Gateway). The next two pictures taken from Arris's user guide shows some details of this router(Wi-Fi) enabled.

Basically it has 4 LAN connections and a Wi-Fi access point to connect to all the devices in the Home (Oceanic calls it Home Wi-Fi). It has capability for 2.5 GHZ and 5 GHz ranges. The security is WPA2-Personal with AES. The Wi-Fi router has pre-configured username and password on the box which can be changed later accessing a WebGUI.

It so happened the Windows 10 interface tried to make a broadband connection to this router which did not work effectively (connected but with limited capability). This did not allow connection to the Internet. The trouble shooting using Windows indicated it was a 651 error.


This error arose out of WAN Mini-port (PPPoE), an error reported by many on the Internet. The file in question raspppoe.sys appears to be working well. More over, the latest raspppoe.sys file does not support Windows 10 (private communication from raspppoe.com site).

Neither Oceanic Time Warner's nor Arris's help desk could provide any assistance.

Moreover Arris 1670A according to an old userguide (was pre-Windows 10) there was no mention that it supports Windows 10.
This is how connectivity was established.

I removed all connectivity information including the old Wi-Fi connection with the older cable modem+ LinkSys router.

I started from basic the step by configuring the Network adapters.


Finally I was able to connect to the Wi-Fi from Cable modem using the following settings:
Here is how the Network Connections look:
