Most hard drives store data using magnetic properties, but unfortunately those are only good for about 10 years. This might be great for your status updates, but if you’re storing photos or government documents, your best bet for a long-term future might be archival paper (or stone and a chisel). But MIT Tech Review reports that scientists have figured a way to etch data onto sheets of tungsten and silicon nitride in the form of QR codes to store data for the theoretical long term — like a million years. Whether or not we’ll have software to decode it then is another problem altogether.

Nimble Storage of San Jose wants to go public on the New York Stock Exchange and indicated as much in a registration filing with Securities & Exchange Commission (SEC). The 5-year-old company, which makes flash-based storage systems and competes with the likes of EMC and NetApp, wants for raise up to $150 million and will likely trade under the symbol, NMBL. No further details on how many shares it hopes to see become available. It has raised about $40 million from Sequoia Capital, Accel Partners and Lightspeed Venture Partners.

Make of it what you will, given that Huawei was founded by an ex-Chinese-military engineer and has had lots of mud thrown at it from the West, but the telecoms equipment firm maintains it’s never been leaned on by any government or agency anywhere, ever.

In the foreword to a security white paper released on Friday, Huawei deputy chairman Ken Hu said the firm had never been asked to change hardware or software, provide access to its technology, or offer up people’s data. That’s certainly a poke in the eye for companies operating in the U.S., which have to abide by the CALEA backdoor rules and cooperate with surveillance programs.

If you’ve ever wanted to use the Couchbase NoSQL database but didn’t feel like managing servers, a San Mateo, Calif.-based startup called KuroBase says it has you covered with its new service. Cloud databases are already pretty popular with web developers running MongoDB, Postgres and even CouchDB (kind of, technically), but I believe this is a first for Couchbase. It could be popular, though, especially if developers are keen on Couchbase’s new ability to sync data between mobile devices and a central database.

We have been hearing about things like YARN and high availability for a few years — they’ve even been incorporated into some commercial Hadoop distributions — but now they’re finally part of the official Apache Hadoop code base. Technically version 2.2.0, “The project’s latest release marks a major milestone more than four years in the making, and has achieved the level of stability and enterprise-readiness to earn the General Availability designation,” according to an Apache Software Foundation press release.
