OS X users, here’s a QuickLook plugin to display the dimensions and size of an image in the title bar instead of the filename

There are many sites that list useful QuickLook plugins for OS X users but many of them have missed this one. Now, when you’re in Finder, a simple tap of the spacebar can show you the dimensions of an image and its file size in the title bar:

But wait, there’s more!

This plugin can also preview and generate Finder thumbnails for unsupported images formats like :

AND it comes with a Spotlight plugin to display informations of unsupported images (WebP, bpg, Portable Pixmap) in Finder’s inspector window. But really, it had me at displaying the dimensions and size of an image, since that’s information I’ve often needed after receiving an image. Real all about it at the project’s GitHub page or just download the installer.

GalliumOS: The Linux Distro For Chromebook

The Google Chromebook is no stranger to modifications. Despite the fact that it’s a fairly locked platform, there are many projects dedicated to replacing the operating system that it ships with. All these projects are great, but they all have one thing in common – placing in a Linux distribution not designed from the ground up specifically for Chrome devices.

This is where GalliumOS comes in. It’s a specialized Linux distribution based on Ubuntu for Chromebooks only. Is it worth using? Let’s find out!

Protecting Apache Server From Denial-of-Service (Dos) Attack | Unixmen

Denial-of-Service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. A distributed denial-of-service (DDoS) is where the attack source is more than one–and often thousands of-unique IP addresses.

What is mod_evasive?

mod_evasive is an evasive maneuvers module for Apache to provide evasive action in the event of an HTTP DoS or DDoS attack or brute force attack. It is also designed to be a detection and network management tool, and can be easily configured to talk to ipchains, firewalls, routers, and etcetera. mod_evasive presently reports abuses via email and syslog facilities.
