In Brief

A new study might help confirm that D-Wave Systems’ quantum computer chip might actually be what it claims to be. Conducted at the University of Southern California, where the D-Wave system owned by aerospace contractor Lockheed Martin is based, a team of scientists has concluded that the 128-qubit processor “behaved in a way that agrees with a model called ‘quantum Monte Carlo,’ yet disagreed with two candidate classical models.” In two weeks at our Structure Data conference, D-Wave CEO Vern Brownell will talk about what quantum computers can do and how they’ll be available as cloud services.

In Brief

Tableau and Splunk, two of the more successful (and ubiquitous) data startups turned public companies over the past several years, have partnered on a new connector that lets Tableau users access Splunk as a data source within the analytics software. However, it’s not just the existence of a connector that’s valuable for users, but what it means — that they can now combine Splunk data with other data within Tableau to visually analyze all of it together. As Tableau grows more popular, partnering with it is becoming a popular move for everyone from large software vendors to small startups such as BigML.

In Brief

An e-commerce startup called Reflektion has raised an $8 million series B round of venture capital for its technology that helps retailers personalize the online shopping experience for consumers. Intel Capital led the round, and Nike and several private investors also pitched in. This seems like the latest thing in marketing — not just targeted advertising but entire tailored experiences for individual shoppers. It does add an Amazon-like recommendation experience, although one might fairly question whether most product catalogs are large enough to warrant it.

DueDil, a rather clever London-based outfit that uses open (and purchased) datasets to provide due diligence services, has raised another $17 million in a Series B round. The cash came from existing investors Notion Capital, Passion Capital and round leader Oak Investment Partners, and it comes on top of the $5m I reported on in April last year. In those 10 months, the “real-time decision intelligence” firm said, it has gained traction among most of the FTSE 100 companies. Customers can currently use the DueDil API to find out information about companies and directors in 22 countries, and the fresh capital injection should help spread that coverage.

In Brief

NoSQL startup DataStax announced on Wednesday that it has added an in-memory option to its commercial version of the Cassandra key-value database. Cassandra is seeing an uptick in adoption right now because of its scalability and ability to span data centers, and the ability to serve data from memory instead of disk will make it a lot faster, too. If the approaches of startups like DataStax, MemSQL and others are any indication, it looks like databases of the future will feature broad ranges of capabilities, data formats and storage options.

RunKeeper tracked what its users were up to in Sochi during the Olympics and found they ran the equivalent of about 78 marathons. It’s an interesting nugget, but part of a much larger picture about learning how, when and where people exercise. Read more »
