Learn R interactively with the swirl package

R, the statistical computing language of choice and what I use the most, can seem odd to those new to the language or programming. And I think this what holds a lot of people back and what keeps people stuck in limited software. The swirl package for R helps beginners get over that first hurdle by teaching you within R itself.

New Clues in the Target Breach

This is a very well written summary about recent Target security breach. I would encourage you to check it out, if you are into technology a lot.

An examination of the malware used in the Target breach suggests that the attackers may have had help from a poorly secured feature built into a widely-used IT management software product that was running on the retailer’s internal network.

… This knowledge base article (PDF) published by BMC explains the Best1_user account is installed by the software to do routine tasks. That article states that while the Best1_user account is essentially a “system” or “administrator” level account on the host machine, customers shouldn’t concern themselves with this account because “it is not a member of any group (not even the ‘users’ group) and therefore can’t be used to login to the system.”

“The only privilege that the account is granted is the ability to run as a batch job,” the document states, indicating that it could be used to run programs if invoked from a command prompt. …

Octave 3.8 has been released and it has a GUI

Octave is a free, open source language for numerical computing that is mostly compatible with MATLAB. For years, the official Octave project has been strictly command-line only which puts many users off — particularly those who were used to the graphical user interface (GUI) of MATLAB. Unofficial GUIs have come and gone over the years but none of them were fully satisfactory for one reason or another.

As of the 3.8 release of Octave on 31st December 2013, this all changed when Octave started shipping with its own, official GUI. It is currently considered as ‘experimental’ by the Octave team and is obviously rough around the edges here and there but it is already quite usable.
