Aug. 16, 2012 SVForum Elaine Wherry Recruiter Honeypot

On August 16, 2012 in Palo Alto at SAP, SVForum’s Engineering Leadership SIG hosted Elaine Wherry’s presentation “The Recruiter Honeypot.” Back in 2005, she co-founded Meebo and worked as Meebo’s Chief Experience Officer and Vice President of Product. Needing recruiters to find the best JavaScript experts, she created an online persona named Pete London.

Wherry learned about the dark side of recruiting. Some recruiters are not always honest with you. They may try to poach your people, even imaginary people. Many of them used to work with car rental agencies. Only one recruiter managed to figure out that Pete London did not exist. I was amazed that nobody checked if a Pete London had ever graduated from Stanford. Doing research takes time and time is money.

Wherry also learned about better recruiting strategies. Don’t try to assemble your own team of superheroes. Find an experienced manager who already knows a bunch of people who understand the technology and can work together. More people will follow a manager with proven leadership than a company with stock options.

Don’t try for an exact match. Be flexible and broaden your search. Good people are constantly moving from project to project to learn new skills. The best candidates may not even be looking.

Join professional organizations and networks. Become an active volunteer and you will have the chance to work with potential candidates before you hire them. LinkedIn is a powerful tool for professional networking. Remove boilerplate from your e-mails. Write a personal message by removing the first person “I” and try using the second person “you” to be more direct. Specific facts about the company and position are better than general adjectives. Keep paragraphs to one sentence. Once you develop a conversation thread, follow through to establish a relationship.

The best leaders tell a story that talented people want to be a part of.

Gary Mantalas of Ryzen and Jeff Richardson of Empowered Alliances spoke about their respective companies. Special thanks to Tom Delora, Sam Hahn, and Ron Lichty.

May 28, 2012 The New Yorker

On May 28, 2012 The New Yorker’s James Surowiecki wrote “Unequal Shares” about Facebook’s Mark Zuckerberg creating two classes of shares in the IPO in what is called a dual class structure. Google, Groupon, LinkedIn, Yelp and Zynga did the same when it went public. It is a strategy to keep control of a company and avoid short term pressure from investors but the stock can under perform in the market. IPOs are not as attractive as remaining private or being bought by another company.

Feb. 7, 2012 SVForum PWC

On Tuesday February 7, 2012 in Palo Alto at Pillsbury Winthrop, SVForum presented the SVForum Quarterly Venture Breakfast with Pillsbury Winthrop and PricewaterhouseCoopers. The topic was “2011 The Year In Review.” Allison Leopold Tilley of Pillsbury Winthrop moderated panelists Steve Bengston of PricewaterhouseCoopers, Casper de Clercq of Norwest Venture Partners, Steve Goldberg of Venrock and Ann Winblad of Hummer Winblad. They discussed the past year and prospects for the next.

Venture capital investments went up from $23 billion in 2010 to $26 billion in 2011. Fundraising went up from $10 billion in 2010 to $12 billion in 2011. This growth is seen as unsustainable when the top sectors of cleantech, biotech, and medical devices are vulnerable to scaling and regulatory issues. Despite the IPOs of LinkedIn and Pandora, the trend toward VC backed companies going public declined from 75 in 2010 to 50 in 2011. This does not help the unemployed if over ninety percent of job creation occurs after a company has an IPO. The Facebook IPO may generate more Silicon Valley angel investing, but such investment has not generated well paying jobs in the US.

According to the US Dept of Commerce and Wall Street Journal, multinationals over the past decade have cut 2.9 million jobs in the US and moved 2.4 overseas. One result is that over 80 percent of internet growth is overseas where more than 90 percent of the children under 15 live in emerging markets. One place the population may not be growing is in China, where the workforce will peak in 2015 and become the world’s largest economy by 2017 but be surpassed in population by India in 2020. Growth in Europe is unlikely considering their continuing instability as seen in Greece.

Despite more money going in, there are fewer exits. The current situation is unsustainable.

Feb. 6, 2012 Fortune

On Feb. 6, 2012 Fortune magazine’s Adam Lashinsky wrote “The Secrets Apple Keeps” about a company keeping a lid on new products to keep a competitive advantage. It is a paranoid place that is not always a lot of fun to work for. The pay is competitive but people still want to work there for the prestige. Lashinsky also interviewed Google’s  Larry Page. Compared to Apple Google seems more open and fun loving.

LinkedIn’s Reid Hoffman wrote “The Real Way To Network” about building relationships versus traditional networking. Dale Carnegie is still relevant.

David A. Kaplan wrote “Salesforce’s Happy Workforce” about Marc Benioff’s philosophy and practice of trying to do the right thing.

Oct. 27, 2010 SDF LinkedIn Avatara

On October 27, 2010 in Mountain View at LinkedIn, the SDForum SAM SIG hosted Chris Riccomini, Senior Data Scientist on LinkedIn’s Product Analytics team to talk about “Scalable Analytical Processing with LinkedIn’s Avatara.”

Formerly of PayPal, Riccomini worked on LinkedIn’s ”People You May Know” feature and “Who’s Viewed My Profile” product. He talked about the competing priorities between high throughput and low latency and the solution of Hadoop and Voldemort. LinkedIn needed something that would support offline aggregation, event-time aggregation and query time aggregation. It had to run through a Map/Reduce shared interface to power customer facing data products. He described a layered structure from top to bottom. On the top layer is the engine. Below that are the cube, and then the cube query. At the bottom are three elements: transform, aggregator and comparator.

The result was Avatara, a real time scalable Online Analytical Processing (OLAP) System already in production. It has features like select, count, where, group, having, order and limit. Riccomini described the architecture and implementation of its storage and aggregation layers.

One new term I heard was AvatarSQLishBuilder. Apparently, even in a NoSQL environment, the code should still have the look and structure of SQL. My advice for anyone heading into Hadoop territory is to take an experienced SQL database developer with you. Java is not enough in this Wild West show.

Another new term is Yahoo Cloud Serving Benchmark (YCSB). This is a way to compare various cloud products. I thought they were talking about yogurt. More explanation is at:

Sept. 22, 2010 SDF Hadoop Scaling

On September 22, 2010 in Mountain View at LinkedIn, the SDForum SAM SIG hosted Ken Krugler of Bixo Labs presentation “Thinking at Scale with Hadoop.” In the past Krugler has worked with Nutch, Lucene and Solr. Now he uses Bixo, Hadoop, and Cascading, an open source project to speed up large scale web mining and analytics.

When working with Hadoop, traditional SQL developers should think in the map-reduce paradigm of fields/operations/pipes. The logical architecture is a computing cluster providing storage and execution. The execution is divide and conquer. The process steps are map, shuffle and reduce. A value is a set of fields. The key value pairs are exchanged between to the user-defined map and reduce algorithms. The map translates the input to keys and values. The system groups each unique key with all its values. The reducer translates the values of each unique key to new keys and values. Because map and reduce functions only care about current key and value, any number of mappers or reducers can invoke on an arbitrary number on any number of nodes.

Complex workflows require multiple map reduce jobs. Errors can occur when connecting and synchronizing data between them. Not seeing intent from all the low level data can make MR optimization harder. There are ways to deal with this complexity. He thinks you should model the problem as a workflow with operations on records. Cascading has tuples, pipes and operations, FlumeJava has classes and deferred execution. Pig or Hive treat it like a big database and are good for query-centric problems. Datameer (DAS) and BigSheets treat it like a big spreadsheet and are good for easier analytics.

There are experts in Hadoop and experts in SQL database development. It is nearly impossible to find someone who is an expert at both. Find an expert SQL database developer who wants to add some new tools to their toolbox. To get those tools, Krugler recommended the following Hadoop references:

May 25, 2010 SDF Social Networking

On May 25, 2010 in Redwood City at White & Lee LLP, SDForum held a workshop “Grow Your Career & Revenues with Social Media!” with Tim Bailey, President of Alliance-Strategies.

Bailey totally gets social networking. He understands it cannot be ignored and can be used to great advantage when communicating with customers. He talked about how social networks and strategies can work best for individuals and businesses using LinkedIn, Facebook, and Twitter. His advice has helped me connect and do business in a way I could not have imagined before.

Aug. 26, 2009 SDF LinkedIn Voldemort

SDF logo2009 copyBansal Bhupesh copyKreps Jay copy

On August 26, 2009 in Palo Alto the SDForum SAM SIG hosted LinkedIn engineers Bhupesh Bansal and Jay Kreps to present “Project Voldemort: Scalable Fault Tolerant Distributed Storage at LinkedIn”.

LinkedIn takes web scale computing to extremes. They store and manage high read/write loads of massive data sets. Their applications need high scalability and performance but not necessarily features seen in relational databases. Project Voldemort is a distributed, highly scalable Key Value Storage System based on the Amazon Dynamo project using Hadoop and Pig. They talked about its architecture, design choices and future serving many data intensive applications. They want to build a community to solve the huge challenges they face. (I recommend using LinkedIn to find them.)

I think the use of the name Voldemort is sign of a new generation taking over the nomenclature from retiring nerds who used names from Star Trek and Star Wars. I just hope they are not hoping for a magic solution. :-)

At one point they discussed a process that takes several days to run. That needs fixing pronto. I can recommend a good database expert that might be able tune that to a few seconds.

For a more detailed analysis I suggest Richard Taylor’s post at:http://bandb.blogspot.com/2009/09/project-voldemort.html

Aug. 18, 2009 SDF Business Intelligence in the Cloud

SDF logo2009 copyGali Lenin copyGuanlao Arnel copy

On August 18, 2009 in Palo Alto at SAP, SDForum presented “Cutting Edge Business Intelligence in the Cloud” with Lenin Gali of ShareThis. ShareThis has a widget that allows people to share what they find on the web with others on their social network. It doesn’t matter if it is FaceBook, Twitter, MySpace, or LinkedIn. Their clients include Fox Media, UsMagazine, Wired, ESPN, and movies.com. They built their IT on Amazon EC2, Cascading, Hadoop, Hive and MicroStrategy. They use Aster Data for their Data Warehouse. Text from DJCline.com

If you come from a traditional database IT background, I guarantee that you have never seen an operation like this. Cascading is the processing API for Hadoop Clusters. There are pipes, flows, branches and groups. You get event notification, can write scripts and control it at the tuple level. Hive is the data warehouse built on top of Hadoop. It supports non-complex SQL using HQL. You can build a custom map/reduce jobs for complex analytics. You can still make adhoc queries for large data sets. The Aster Data DW in the cloud is scalable commodity hardware with an Massively Parallel Processing (MPP) Architecture. It uses SQL, Map/Reduce, JDBC, ODBC, and is compatible with Extract Transfer and Load (ETL) tools. Aster Data architecture uses PostgreSQL and has a beehive heirarchy. Queens control the cluster and hold metadata while workers process and store it. If the queen fails it is replaced immediately. Text from DJCline.com

They think that all of this is easier to use and lowers their costs. They keep their headcount down and their revenue up. It works for them. The question is whether it will work elsewhere. Text from DJCline.com

July 9, 2009 SDF Social Networking

SDForum copy.jpgbailey-tim-copykanakamedala-sam-copysupplee-ward-copywalker-jules-copywright-ben-copy

On July 9, 2009 at White & Lee LLP in Redwood City SDForum hosted Tim Bailey, President of Alliance-Strategies. Bailey’s presentation was “Social Networking Increases Your Opportunities”.

Before diving into social networking, listen to Bailey. He says social networking is too big for companies and individuals to ignore and there are ways to make the most of it. Think about your brand’s short term and long-term strategy. Who is your audience and what do you want to tell them? What are your strengths and weaknesses?

The most important social networking phenomena are LinkedIn, Facebook, and Twitter. Bailey went through each of them discussing their advantages and disadvantages. LinkedIn is for professionals. Facebook is less formal and more personal. Twitter is wild and still forming. After carefully assessing them, start slowly building your network on the people and companies you know and trust. He thinks you can spend about a half hour a day maintaining it. Keep it honest and fun and people will want to get involved.

Social networking is so huge a topic that it needs at least a one-day seminar just to cover the highlights. The large audience had lots of questions that Bailey tried to answer as succinctly as possible in two short hours. I look forward to hearing more from him on this subject.
