VMware HTML5 Client?


I’ve caught wind of a real HTML5 web client being developed. Its currently very early into development and is released as technical preview fling. To be clear it’s not for vCenter, but we can only imagine the direction this would eventually go. This version of the ESXi Embedded Host Client is written purely in HTML and JavaScript, and is served directly from your ESXi host. So that means it’s specifically meant to run on the host, and controls only the host but it claims to “perform much better than any of the existing solutions”.

Mainly I am happy to hear that there is no Flash dependency in this version of the web client. Maybe the feedback from customer’s is actually being heard by VMware. Maybe we could see this continue to develop into replacing the vCenter version of the flash web client. We’ll have to wait and see, but for now we know that at least something is being worked on and that is better than nothing.

Leap Second Adjustment on June 30th @ 23:59:60 UTC


This is an FYI. There has been some internet/email noise going around regarding the next leap second adjustment which is scheduled for June 30th, 2015 at 23:59:60 UTC. It may cause issues on NTP synchronized devices and operating systems. Several vendors have released KB articles regarding leap second impact on their software.

A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time, or UT1. Without such a correction, time reckoned by Earth’s rotation drifts away from atomic time because of irregularities in the Earth’s rate of rotation. The last leap second happened on June 30, 2012. A number of organizations reported problems caused by flawed software following the June 30, 2012, leap second.

Canada’s Anti-Spam Law – The Rundown

This is targeted to my Canadian readers. Canada has come out with a new Anti-Spam law, dubbed “CASL“. It will affect you if you use email marketing to promote your business to customers and prospects in Canada.


Effective July 1st 2014, when you send commercial email, instant messages, or other electronic marketing messages to residents in Canada, you’re going to have to make sure you are in compliance with the new regulations or face hefty fines. Here’s what you’ll need in order to comply with Canada’s anti-spam legislation:

  • Consent from the recipient, either expressed or implied.
  • Clear identification on the message (your business name and contact information).
  • An unsubscribe mechanism – basically, a way for the recipient to inform you to stop sending them messages in the future.

What’s the point of enacting these three rules?

According to the Government of Canada’s web page for the Anti-Spam Legislation, it’s all about improving online protection for Canadians while “ensuring that businesses can compete in a global marketplace.”

The goal behind the new law is to stop unwanted emails and text messages. Even if the promotional messages you send to customers don’t look like total “SPAM!” you could still be at risk for severe penalties if you don’t follow the new rules. Express consent is required before sending any email. That means that people have to explicitly say they want to receive email, by either checking a box or putting in an email address in a place that clearly states you will be receiving email.

Penalties include:

  • Up to $1 million fines for individuals
  • Up to $10 million fines for companies
