Discover VMware Technology Network – Global Forums

Discover VMTN is a blog series that will bring to light the features and functionality within the communities platform that are lesser known, but incredibly useful. This week we start with…

VMTN Global Forums by Language

VMware has offices in 20+ countries, has 30+ localized sites, but last month, VMware Technology Network had only a few scatted forums dedicated to enabling peer-to-peer conversations for our global customers.

That gap has been filled with the launch of VMTN Global Forums.

Communities are an integral part of being a VMware customer. When a customer buys, deploys, or builds on a VMware product, they become a part of the VMware Technology Network, or as our bigger community ecosystem is sometimes called, the vCommunity. VMTN Global Forums by Language now provides a platform to share knowledge, resources, opinions, and gain support, for customers worldwide.

These Forums each have a committed moderator who regulates content to ensure that there is no third-party advertising, and that VMTN’s Code of Conduct is maintained. Check out our list of new Forums and their moderators:

French: @LucD ; @FranckRookie

Italian: @ldelloca

Polish: @inleo

Russian: @AntonVZhbankov

Spanish: @dquintana

Brazilian Portuguese: @rcporto

Japanese: @gowatana

Arabic: @MRoushdy

German: @wila ; @peetz ; @schepp ; @a.p.

Turkish: @ademyetim


So now it comes down to this… Did you deploy a VMware product today? How? Are you upgrading your vSphere from 5.5 to 6? Have you? Head to the forums and engage, whether it’s answering discussions or starting them – from where ever you are in the world.

Best Paper Award at FAST 2017 goes to “Application Crash Consistency and Performance with CCFS” by Vijay Chidambaram!

Abstract: Recent research has shown that applications often incorrectly implement crash consistency. We present ccfs, a file system that improves the correctness of application-level crash consistency protocols while maintaining high performance. A key idea in ccfs is the abstraction of a stream. Within a stream, updates are committed in program order, thus helping correctness; across streams, there are no ordering restrictions, thus enabling scheduling flexibility and high performance. We empirically demonstrate that applications running atop ccfs achieve high levels of crash consistency. Further, we show that ccfs performance under standard file-system benchmarks is excellent, in the worst case on par with the highest performing modes of Linux ext4, and in some cases notably better. Overall, we demonstrate that both application correctness and high performance can be realized in a modern file system.

From 0 to Blinking LED

By John Hawley, Open Source Software & Hardware Developer

While I was in India recently, I went to a software conference (PyCon India), and gave a talk on open source hardware and MicroPython. There’s a lot of interesting crossovers between open source software and the fledgling world of open hardware, the neat things going on to make MicroPython worth a look, but I don’t want to talk about those. What I want to talk about the people, because the people I met were much more fascinating than code or circuits.


I got to spend a couple of days during the code sprints, a typical part of most PyCons where attendees get the opportunity to vote with their feet and go and work on code for any project that’s got folks willing to work with you. This is actually really helpful for both the upstream developers, as they get a chance to see new users try and use their projects. It exposes pain points for new contributors, and it’s actually a really amazing thing to get to work on a project when you can just talk across a table about a problem you are having, and possibly work out it’s a bug and go write your first patch for it with the core developers themselves. In Pune there were folks writing their first commits for Django, Mailman 3, and a whole slew of other projects that I couldn’t even begin to list, because I was off in a separate room working with folks to just introduce them to MicroPython and micro-controllers.

I have no idea how many folks came through the room, but everyone who came through was able to borrow a NodeMcu from me, get their own systems setup to be able to flash MicroPython on the boards, and get leds blinking at the very least. There were the expected Linux users, who for once had the easiest time doing this as the serial drivers are all built into Linux. There were Windows users helping each other figure out how to talk to the boards, which invariable required a driver download, and there were the indomitable Mac users who had, by far, the hardest time getting things working, but everyone prevailed.

When people got their LEDs blinking, there was genuine accomplishment, and there was a new understanding of how these things work. The more adventurous folks went further and did a lot more exploring. One gentleman hooking up as many LEDs as he could, got them all blinking and was writing patterns as if the light was dancing across the bread board.

Another gentleman, not being content to just blink and LED snagged one of the I2C temperature and humidity sensors we had, and with little knowledge of even what I2C was, eventually able to not only read data from the device, but realize the one he had was miss-calibrated, and write appropriate software to offset it back into being reasonably accurate.

One particular individual, a lawyer by profession who had an interesting in learning to code, but kept having trouble trying to learning it the more traditional ways, found that getting LEDs to blink was far more tangible, and helped the code make more sense to her. By the time I left India she was understood not only how to blink an LED, but what I2C was, how to interface with a PWM controller and blink some LEDs. Since then she’s gone far beyond that, and learned how to connect to make a device that can independently blink if she’s mentioned on twitter, and published her work up on github. There’s a lot of firsts there for her, and if your interested in reading her own impressions, take a look at her own write up at

Suffice it to say, sometimes it’s not about how amazing an algorithm is, or how prolific a project is. Sometimes it’s about getting an LED to blink.

John Hawley is an open source software and hardware developer, because he sees fundamental value in being open, and open collaboration. He’s built multiple star ship bridges, robotic dogs, and content distribution and mirroring system. You can follow him on Twitter @warty9.

A Dynamite and Dynamic Community Warrior

*With the below announcement, nominations are now open for winner #4!*

Screen Shot 2017-03-27 at 10.23.14 AM

I am happy to announce the newest recipient of the Community Warrior badge is Ariel Sanchez Mora. Congratulations Ariel! Ariel is truly an embodiment of what he refers to as the vCommunity. He encourages, enables, and emphasizes the success of others through his involvement with not just VMTN, but VMUG, vBrownBag, and vExpert.

I received various nominations for Ariel, but there was one that truly stood out. Check it out:

@nscuola: He’s the reason that I and many others are vExperts in the first place. His contributions are not just related to the VMware community. He’s a VMUG leader and a d*mn good one at that. He’s an integral part of vBrownBag. He should basically have a blue check mark on Twitter since he’s always on there promoting community and virtualization as a whole. Ariel is also one of the more genuine, positive people that I know and encourages everyone who he meets to get more involved in the VMware family (not just community). He’s always pushing for people to give presentations at VMUGs, apply for vExpert, take a certification exam, and just try to do more.

@Nscuola, was then able to announce Ariel’s award at the NY/NJ local VMUG meeting – Ariel’s last before moving to Pittsburgh, PA:

As a community enthusiast, I wanted Ariel’s Community Warrior blog to be dedicated to sharing his passion for the different organizations he is committed to. Learn what he gains through his involvement, and how you can gain the same:


VMUG (VMware User Group) (

This is where you find people that talk VMware to hang out with. I like to show up early and make sure I meet at least two people I have never talked to before, and I stay around when the event ends. It’s also a great idea to talk to the leaders and ask if you can help, whether presenting or helping do something for any future event. The key here is learning about the day’s topics, but also take the opportunity to make local connections. I’ve been extremely lucky and was able to grab lunch, coffee or a drink with people I met at a VMUG with whom I shared certification targets, VMware design questions, or common setups. 

After years of being a participant, I asked to become a leader, and Mike Martino accepted me in NYC. You can see stuff we do at for ideas (and every VMUG has their own ideas) so your focus should be on what you can do for your local one. And if going to an event is difficult, save a PTO day and at least go to the UserCon – these are one day mega events which you just can’t miss!


vBrownBag (

This is where you learn about the latest in tech or get additional help for certification exams. These are 80% online and 20% real life. vBrownBag is a volunteer organization of people trying to help others learn virtualization technologies. Most known for publishing free YouTube videos on all sorts of topics, they are sometimes sponsored to organize live TechTalks at major conferences, such as VMworld. I found this community through word of mouth, fell in love with the format and general vibe, and became a presenter, and later crew member. Getting involved with vBB has been one of the greatest experiences of my life – it’s a lot of positive energy all around. This is where you can not only get better, but also make friends all over the world!

BONUS: – Ariel’s vBrownBag interview with me in my first month working as VMTN Community Manager at VMworld.


vExpert (

This is what you get for helping others – and being a vExpert is awesome! The vExpert program is directly run by VMware to recognize champions for VMware technologies. Those that attain the award get access to perks such as home lab licenses, vendor perks (the Pluralsight subscription is my favorite) but most importantly access to a lot of folks who in many ways are on the bleeding edge of VMware technologies. I love helping people aspiring to make vExpert – reach out on twitter and I will be more than glad to help you! Check out a more thorough explanation of vExpert, including my past submissions, here:
