{"_id: "2",
"org" : "MUG",
"sponsors":["company1","company2"],
"state":"MD",
"membership":120}

{"_id: "3",
"org" : "JUG",
"state":"DE",
"membership":21}

{"_id: "4",
"org" : "JUG",
"state":"CA",
"membership":2000}

The following query would produce an aggregate from this collection:
db.collection.aggregate({$group : { _id : "$org", totalMembership : { $sum : "$membership" } } }, { $match : { org : { $eq : "JUG"} } })

This is equivalent to the SQL statement:
SELECT org, SUM(membership) as totalMembership FROM collection
GROUP by org
WHERE org is "JUG";

{"_id: "JUG",
"totalMembership": 2221}

...where the results are grouped and sorted. As you can see, the aggregate is a reduced set despite the fact that one of the documents having slightly different structure. The "." notation acts as a "|" or pipe function, similar to that found in UNIX shells, allowing for the chaining of operations.

Finally, Max covered index construction and optimization, how not to index everything, and finally how to profile your queries through the "explain plan" to understand what indices’, if any, are being used during your queries and when.
2. Rob Moore's presentation on tricks-to-teach MongoDB showcased potential depth with the product. Imagine MongoDB acting as a pub-sub message broker! Building upon his asynchronous (and super-fast) Mongos client, he was able to demonstrate callback functionality within Mongo so that modification events to a document or collection were passed back to subscribed mongos clients much a JMS broker would do so. Although this is not part of the supported product, it did entice us to dream of certain possibilities.
3. Auto-Sharding and matters of scale. The sharding capability of MongoDB makes it attractive and a viable alternative to some big data solutions! Now, with MongoDB 2.4 release, the pain of shard management has gotten easier with automated shard extension support. So, as my Mongo cluster grows and I need to add more members to my shard collections, I "simply" startup a new MongoDB server instance and add it as a member of my shard collection. The distribution of key space across the new member is handled incrementally during normal shard collection rebalancing. Of course, if you didn't know, MongoDB also has a mapReduce implementation using JavaScript. Before you bash it, consider the performance of mapReduce across a shard collection filtered by time where all the working documents are in memory - yep, that's how MongoDB rolls. MapReduce, given your use case and tuning, can plow through documents faster than you would expect. (Sorry for the caveats, but that's life, right?)
There were other topics discussed, of course - spatial querying, security, a RedHat OpenShift highlight, and others. One thing new I did do that day was connect to the mongodb IRC on FreeNode through a Chrome add-in and help someone with their document "_id" (the shard key) strategy. Yeah old-school collaboration!
 

Technical Software Configuration Management (TSCM) is the application of the latest and greatest technologies to automate and streamline configuration management processes used specifically for software development. This role is great for up and coming junior developers to both gain business knowledge and ease into a technical position on any team.

April 9th at Praxis Engineering, 135 National Business Pkwy, Annapolis Junction, MD 20701 from 7:30 - 9:00 AM

For more information please visit www.technicalsoftwareconfigurationmanagement.org

Additionally, with sequestration and the fast pace of technology there is a trend toward automated testing and Technical Software Configuration Management (TSCM technicalsoftwareconfigurationmanagement.org). Presently, these two tasks are performed manually which causes them to be very time intensive and worse than that they are often the slow points in trying to achieve our customer's mission. In this presentation, we are going to outline a path for Cultivating our personnel and processes toward the automated time and mission saving approach.

Who should attend this presentation and why. Your business development team might want to consider using Cultivation and TSCM on upcoming proposals as differentiators. Small business owners and other executives that want to create a cultivating environment within their company. Project managers and technical leads can also use these concepts and initiatives on a smaller scale to achieve success. In the end, Cultivation promises to help a broad spectrum of businesses successfully hire and retain junior talent while building the superstars of the future

Congressman Elijah Cummings leads off the presentation on March 28th followed by a briefing on Cultivation and Technical Software Configuration Management (TSCM) from Brian E. Walsh the CTO of Interclypse, followed by an update on the BASE Business Initiative (BBI) and networking activities. These meetings are free, open to the public, and require no RSVP. 

Additionally, Interclypse spoke about Cultivation (www.teamcultivation.org) a discipline for identifying and mentoring tomorrow's superstars by immersing them in a positive, collaborative, and empowering environment that encourages learning and career development. Cultivation encourages sharing of these personnel across teams where they continue to grow their career while influencing others through collaboration, mentorship and knowledge sharing.

Specifically Interclypse acknowledged two unique scenarios that Cultivation helps address.

Scenario one. Due to budget reductions at our customer, Cultivating junior candidates to fill more of the open positions provides our customer with a value added alternative.

Scenario two. A given customer likes their existing senior engineers and desires to have more of those same type of engineers. It has proven to be extremely difficult to find similar engineers for a multitude of reasons; however, Cultivating new senior engineers using the existing engineers that the customer already likes can be an excellent value added alternative that meets all of the needs of our customer.

In closing, Interclypse thanked all their current partners while acknowledging that they can not accomplish the fun and exciting things they do without the support of such great partners. Interclypse also looks forward to working with the other great companies attending the event.

The new Trinzic 800, 1400, 2200 and 4000 series appliances are suited for a range of environments from small branch offices to medium-sized enterprises and regional offices to large data centers, service providers and disaster recovery sites.

“Appliance-based delivery of IP network services, such as domain name resolution and IP address assignment, has become an industry best practice for any size organization,” says Kevin Dickson, Vice President of Product Management at Infoblox. “Purpose-built appliances are more reliable, secure, manageable and scalable than legacy approaches, such as software running on general-purpose servers.”

Infoblox introduced its first integrated, purpose-built IP network services appliance in 2001 and is committed to meet evolving enterprise and service provider network hardware requirements, ranging from performance and security to reliability and management capabilities. This new generation of appliances continues that tradition with:

Energy Efficiency: Highly efficient components, intelligent power management, consumption and cooling features, such as turning off unused Ethernet ports; power supplies are in compliance with environmental standards, including ETSI EN 300 019-1-3, Energy Star and 80 Plus efficiency.
Lights Out/Remote Management: Proactive monitoring and alerts for power, temperature CPU usage issues and more; remote management features reduce on-site maintenance visits resulting in more cost-effective operations, and Intelligent Platform Management Interface (IPMI) 2.0-compliant for enhanced remote site communication and management.
High Availability: Redundant and field-replaceable power supplies, fans and disks as well as the use of error-correction code (ECC) memory providing a high level of stability and reliability.

About Infoblox

The name change becomes official next week, but Atkinson is briefing people in the industry about the move. With the new name, XIO will sharpen its focus on solid state storage and gear up for a possible run at going public.

The vendor will continue to build on its ISE architecture, and is renaming its SSD-based ISE system Hyper ISE. The system first launched earlier this year as Hybrid ISE.

“XIO sounds like extreme IO, which is exactly where we want to be with our concentration on performance-driven storage,” Atkinson said.

Atkinson said Hyper ISE “is the same physical product” as Hybrid ISE, but its performance has been jacked up considerably due to improvements in the firmware and the algorithms used to tier data. XIO claims one Hyper ISE system can deliver 200,000 IOPS in a 14.4 TB, 3U box.

Hyper ISE uses multi-level cell (MLC) SSDs and 10,000 RPM SAS drives in one enclosure. Xio sees the system as a good fit for running databases, virtual servers and virtual desktop infrastructures (VDIs).

“We built Hyper ISE for performance-starved apps,” Atkinson said. “This is the next turn of the crank. We were talking about 60,000 IOPS before, but 200,000 IOPS is an awful lot better.”

Even with ISE as its centerpiece, XIO is a different company than when Atkinson replaced Casey Powell as CEO. Senior management now includes industry veterans COO George Symons and chief strategy officer Jim McDonald. Like Atkinson, both have worked at EMC. The notable holdover is CTO Steve Sicola, who came to Xiotech when it acquired the Advanced Storage Architecture group from Seagate and turned its technology into the ISE platform.
