The future is encrypted, but your government says that’s not good

On the same day that an article titled Security and Privacy on the Encrypted Network: The Future is Encrypted was published by an information security research and advisory firm called Securosis, Eric Holder, the U.S. Attorney General, was criticizing technology companies for making it more difficult for law enforcement agencies to track and prosecute criminals. That was a not-very-subtle dig […]

Interesting articles on Data Science, and a cool image

Interesting articles on Data Science, and a cool image

Data Science and cool graphics. I’ve always loved cool, eye-catching graphics. Who doesn’t? Data Science? That’s the hottest field in the job market right now. And I think will remain so for as long as data remains currency. I guess that’s why I’ve been retraining myself to become a Data Science person. So put those two together and you’ve got […]

Adobe Photoshop now available for Chromebooks, but…

In partnership with Google, Adobe is now offering Photoshop, its flagship photo-editing software, on Chromebooks. But, and there is a but, that does not mean that all Chromebook owners/users will have access to Photoshop right now. More on that in a bit… Access to Photoshop, for the lucky chromebookers, will be via Adobe’s Creative Cloud program, a fee-based membership program […]

Mark Shuttleworth on Western media, Iraq, IS and Ukraine

It’s very rare that the CEO of a technology outfit that’s based in the West takes an open stance on hot-button geopolitical issues. It’s even rarer that that position is (somewhat) counter to generally held opinion in the West. But that’s what Mark Shuttleworth has done. Remember Mark Shuttleworth? He’s the founder of Canonical, the company behind a very popular […]

Using GNOME Boxes to create and access local virtual systems on GNOME 3.14

Using GNOME Boxes to create and access local virtual systems on GNOME 3.14

GNOME Boxes is a native GNOME 3 application for accessing remote machines and local virtual systems, primarily using the libvirt technology. Consider it an alternative to VirtualBox and VMPlayer. It’s being a usable application for quite some time, but with the release of GNOME 3.14, I decided to give it a test drive to see how far it has come. […]

How to install TwitteR, a Twitter client for R

How to install TwitteR, a Twitter client for R

Installing packages in R is pretty easy, if you know the name of the package you wish to install. Just pass the name of the package to the install.packages() function. Once that’s done, load the package by passing its name to the library() function. So it’s a fairly easy and straight-forward process, right? But it wasn’t so when I attempted […]

Patched Bash still vulnerable to Shellshock

Patched Bash still vulnerable to Shellshock

The bug that was discovered and patched in the Bash shell is still vulnerable to code injection attacks. And the latest is that the bug, now officially known as Shellshock, is being exploited by a computer worm. But nobody seems to know the extent to which the attacks have been successful. The problem with Shellshock, is that many of the […]

Bash susceptible to environment variables code injection attack

Bash susceptible to environment variables code injection attack

A security adversary posted at Red Hat’s security blog and referenced at US-CERT has warned users of the Bash shell of a “specially-crafted environment variables code injection attack.” That means UNIX-based operating systems that use the Bash shell are affected. That includes all Linux distributions and Apple’s Mac OS X. According to the blog post cited above: … the vulnerability […]

DevAssistant: A developer’s best friend

DevAssistant: A developer’s best friend

One application I came across while testing an installation of the main edition Fedora 21 alpha is DevAssistant. (See Fedora 21 Workstation: GNOME 3. KDE and Anaconda screenshots.) DevAssistant automates the process of setting up development environments for a few of the most popular programming languages and development frameworks. Languages supported are shown in the screenshot below. Just after a […]

Mozilla is phasing out SHA-1 based signature algorithms

Mozilla’s Security Engineering Team has announced that they are proactively phasing out the SHA-1 based signature algorithms for digital certificates, stemming from a concern that it too, like the MD5 hash algorithm, could be susceptible to collision attacks. Here’s an excerpt from the official announcement: SHA-1 is nearly twenty years old, and is beginning to show its age. In the […]

How to install Oracle JRE and make it the default JRE on Ubuntu 14.04

How to install Oracle JRE and make it the default JRE on Ubuntu 14.04

A few hours ago I had to install DataStax OpsCenter from the DataStax (community) repository on a new installation of Ubuntu 14.04. DataStax OpsCenter is a browser-based management application for DataStax Enterprise, DataStax Community and Apache Cassandra, a distributed NoSQL database. Cassandra/OpsCenter requires Oracle JRE, but applications installed using Ubuntu’s package manager are hard-wired to use OpenJDK JRE. So if […]

How to set up a 3-node CoreOS cluster, just for fun

How to set up a 3-node CoreOS cluster, just for fun

“CoreOS is a new Linux distribution that has been rearchitected to provide features needed to run modern infrastructure stacks.” That’s geek-speak for a Linux distribution that makes it (not-so-) super easy to run fun things like Linux containers and containerized applications on commodity hardware. That’s one of the trending things in the business, and it’s the kind of stuff I […]

How to install Oracle JRE on Fedora 20 and use alternatives to switch between it and OpenJDK

How to install Oracle JRE on Fedora 20 and use alternatives to switch between it and OpenJDK

All the Java components installed on Fedora (20) are provided by OpenJDK (Open Java Development Kit), a Free Software implementation of Java SE (Standard Edition). It’s all you’ll need except when you have to install an application that requires Oracle JRE (Java Runtime Environment). One such application is the community edition of Datastax Cassandra, a NoSQL database. I thought I […]

Is systemd as bad as boycott systemd is trying to make it?

From just a purely end-user perspective, systemd is an application that I’ve come to like a lot. And I think that its adoption by all Linux distributions will make it easier to manage Linux systems. But it has come under heavy criticism from some quarters – for trying to be a Swiss-army-knife-type application. One that does practically anything and everything, […]
