DNA collection of arrested individuals

This month, the Supreme Court will hear arguments on the issue of whether it is constitutional for the State to require DNA collection of arrested individuals.  The case is Maryland v. King.  The argument is set for February 26, 2013.

As way of background:

  • The federal government and at least 26 states (including California, Illinois, and Florida) take DNA samples from some or all who are arrested but not yet convicted of serious crimes.
  • Last month, President Obama signed into law the Katie Sepich Enhanced DNA Collection Act.  The statute will help pay the start-up costs for other states to begin testing people who are arrested.

So what does this issue mean?  The issue is whether the State, without a search warrant, can take a DNA swap of an arrested individual – who has not been convicted.

The Maryland Court of Appeals stated the 4th amendment, which bars unreasonable searches, protects people who haven’t been convicted from having to provide DNA evidence.  In addition, the court stated, “Although arrestees do not have all the expectations of privacy enjoyed by the general public, the presumption of innocence bestows on them greater protections than convicted felons, parolees or probationers.”

The Maryland Court of Appeals further explained that DNA samples “contain a massive amount of deeply personal information.”

Facebook is collecting your data — 500 terabytes a day

With more than 950 million users, Facebook is collecting a lot of data. Every time you click a notification, visit a page, upload a photo, or check out a friend’s link, you’re generating data for the company to track. Multiply that by 950 million people, who spend on average more than 6.5 hours on the site every month, and you have a lot of information to deal with.

Here are some of the stats the company provided Wednesday to demonstrate just how big Facebook’s data really is:

  • 2.5 billion content items shared per day (status updates + wall posts + photos + videos + comments)
  • 2.7 billion Likes per day
  • 300 million photos uploaded per day
  • 100+ petabytes of disk space in one of FB’s largest Hadoop (HDFS) clusters
  • 105 terabytes of data scanned via Hive, Facebook’s Hadoop query language, every 30 minutes
  • 70,000 queries executed on these databases per day
  • 500+terabytes of new data ingested into the databases every day

“If you aren’t taking advantage of big data, then you don’t have big data, you have just a pile of data,” said Jay Parikh, VP of infrastructure at Facebook on Wednesday. “Everything is interesting to us.”

Parikh said the company is constantly trying to figure out how to better analyze and make sense of the data, including doing extensive A/B testing on all potential updates to the site, and making sure it responds in real time to user input.

“We’re growing fast, but everyone else is growing faster,” he said.
