Let’s take our new knowledge for a test drive with this puzzler: Why would adding a field to qf cause our result set to actually shrink in size?
I first heard about Blaze from NumPy’s original developer’s blog back in December 2012. Recently InformationWeek announced that DARPA was funding the project to the tune of $3 million dollars.
Not so long ago, businesses didn’t care about information outside the normal structure of trusted outlets like print media, trade journals, academic research and other trusted system-generated information.
If you are working on Big Data and its bleeding edge technologies like Hadoop etc., the primary thing you need is a "dataset" to work on.
Nicolas Dugué and Anthony Perez from the University of Orleans introduce new techniques to detect social capitalists on Twitter using Graph Databases.
It isn’t until we encounter flawed design that we are jolted out of our flow and forced to make choices that don’t seem to fit with either our expectations or the natural course of our activity.
If you’ve been struggling to get Python adopted at your place of work, this brochure might help as it showcases how Python is used in business in various fields from industry and science to education and government.
For instance, the social networks of the Iliad and Beowulf look more like actual social networks than does the social network of Harry Potter. Real social networks follow a power law distribution more closely than do social networks in works of fiction.
I travelled to Ireland last week, to attend the second meeting of the European Data Forum (EDF). The EDF provided travel support for my trip, and I am grateful to them for that.
Today’s facial recognition software lies at an interesting intersection of three concepts: How long things are stored for, pictures in which a person appears, and people who can recognize faces in a photo (and tag them).
GIS, an acronym that brings joy to some and strikes fear in the heart of those not interested in buying expensive software. Luckily fight or flight can be saved for another day because you don’t need to be a GIS jock with a wad of cash to work with spatial data and make beautiful plots.
A few months ago, I did published a post on negative values in triangles, and how to deal with them, when using a Poisson regression (the post was published in French). The idea was to use a translation technique...
Recently I was puzzled by some behavior Solr was showing me. I scratched my head and called over a colleague. We couldn’t quite figure out what was going on. Well Solr is open source so… next stop – Debuggersville!
Cassandra is known for its good write performance. But there are scenarios, when you might run into trouble – especially when particular use case generates heavy disk IO. This could be the case for columns which receive frequent updates. However, you can avoid those problems, with proper configuration, or just by updating to recent Cassandra version.
WDD is a fully tested, production-ready version of Apache Hadoop 2 that’s free to download. WDD version 3.1.1 includes an enhanced, more intuitive user interface that simplifies Hadoop cluster deployment. WDD 3.1.1 supports SUSE Linux Enterprise Server 11 (Service Pack 2), in addition to RedHat and CentOS.
Following up my last post on how to download files from the cloud with R...
I use R to fix subtitles that are not in sync with my movies. For the example below the subs were showing too early - so I added some time to each sequence in the srt file. For simplicity I used exactly 1 second in the below example.
The Odd/Even sort is a sorting algorithm which uses the concept of the Bubble Sort to move elements around. Unlike Bubble sort, the Odd/Even sort compares disjointed pairs by using alternating odd and even index values splitting the sorting in different phases.
English is a confusing language. I mean, does it really make sense that you can park in a driveway or drive in a parkway? Also, I’ve always been amused that there actually exists a class of words that are their own antonym – so called “auto-antonyms.”
The hidden biases in Big Data, a PlayDoh 3D printer, and much much more in Arthur Charpentier's data links roundup.
MVC 4 Web API project supporting CRUD operations on MongoDB.
Here is a usefull snippet that I stole from qdap::url_dl to download files from my Dropbox to the working directory.
After four days offline, I have to face the truth: I am a computer addict. Here is a diary of the last four days, ostensibly without touching my computer, at work and at home.
