LexisNexis to Open Source Hadoop Alternative HPCC Systems

LexisNexis is planning to release its internally developed supercomputing platform as open source, providing developers with an alternative to the Hadoop framework for large-scale data processing, the company said Wednesday.
LexisNexis has been developing the technology, dubbed HPCC Systems, for the past 10 years, according to the company, which provides a variety of information services to legal firms, libraries, corporations and government entities.

It will run on commodity Linux boxes and will be released in Community and Enterprise flavors. The Community version will have a GNU Affero GPL v3 license.

And there is one important note:

LexisNexis stressed that HPCC Systems won’t involve the release of any of its “data sources, data products, the unique data linking technology, or any of the linking applications that are built into its products.”

It will be very interesting to see how this develops.

 

Laptops in the Law School Lecture Hall – More Research/Observations

They spotted the first student texting 17 minutes into her law school career. Of the upper-year students, the observers could see using laptops, 58 percent used them for non-class purposes at least half the time. Altogether, 87 percent of the upper-year students used laptops for non-class purposes more than five minutes per class. Announcing that students should not surf the Web seemingly made no difference; even as a professor proclaimed such a prohibition, students continued visiting the Internet.

This CSM op/ed piece is drawn from a draft paper by Prof. Jeff Sovern at St. John’s University School of Law. Based on back of room observations of students’ use of laptops, Prof. Sovern speculates that student react to a tension between incentives to pay attention and the temptation to be distracted when not engaged. The result is that upper level students are more likely to be doing something else with the technology available to them during class rather than paying full attention to the lecture.

While the op/ed piece comes down firmly on the side of banning laptops in the classroom, a move Prof. Sovern notes is paternalistic yet shows a “responsibility to their students’ future clients”, the fuller draft leaves conclusions more open and encourages others to conduct similar studies.

The “banning laptops” debate has been ongoing in legal academia for over a decade and it looks like there is no end in sight. The problem is that law schools have spent a large part of that decade encouraging students to purchase laptops, providing them with ubiquitous wireless access, and increasing student reliance on electronic resources. The message at some schools is that law students should use laptops everywhere but in the classroom, a place where many students actually find technology most useful.

I suspect that this problem will continue until law faculty and law students can sort out what it is they are trying to achieve in the classroom.
