I’m currently upgrading Apple OS X Mavericks as we speak. It’s a huge file, 5.29 GB to be exact. Sit back and relax, because it will take sometime to download the new OS depending on the speed of your internet connection. After the download, launch the installation. It requires a reboot. After boot, expect about 45 mins for the installation to complete.

This week Ubuntu Touch makes its arrival. Ubuntu Touch is officially supported on the Galaxy Nexus and Nexus 4 smartphones, but there are other smartphones that Ubuntu Touch will work on. You’ll need to flash your smartphone to install Ubuntu Touch. The intriguing question is, will Ubuntu Touch be the next hot mobile operating system?
There’s a new broadband standard called G.fast with speeds up to 1Gbps over regular copper wires without the need for a fiber backbone. G.fast is scheduled to be approved by 2014. G.fast users should be able to install it without assistance. The self-installing system will eliminate costs for providers that they would have to pay for technicians. This could significantly improve the speed of the rollout. G.fast is meant to support bandwidth-intensive applications. Initial tests resulted 1.1Gbps over 70 meters and 800Mbps over 100 meters over a single cable. Consumers should expect G.fast connections to be available in 2015.
DD-WRT is an open-source Wi-Fi firmware that you can install on select consumer-based wireless routers. I’ve been using the DD-WRT firmware on several Linksys and Buffalo wireless access points for a number of years. In addition, I have also implemented a feature called NoCatSplash.
NoCatSplash is a feature that allows wireless users to be redirected to a special splash page, whether to notify users of a disclaimer, or to make users agree to certain terms and agreement, or simply to advertise a web page. The NoCatSplash feature will prevent users with access to the Internet until they click on the submit button, thereby agreeing to the terms and agreement.
What was lacking with NoCatSplash was authentication. So, with a little bit of research, I found someone’s code at Github that allows simple authentication with NoCatSplash. It’s written in PHP and doesn’t require a database. It’s quite simple, but works flawlessly. The login credentials are kept on a file and can be changed anytime you’ll need to change passwords.
I’ve modified his code to fit my needs. Suffice to say, the code works great as advertised.
Brian Trapp of Linux Journal recently wrote an article on how to create a perfect Raspberry Pi home server. The article talks about how to install an external USB drive, a Samba server for backup, a DLNA server, and a print server. The article is quite straightforward and easy to follow.
Scanners can be a nightmare to work with. I’ve had this Canon MP495 Wireless Printer/Scanner for at least 3 years now. The wireless printing works on all my Mac computers, but I can’t get the device to scan via the wireless network. I even downloaded the latest Canon drivers as well as the latest MP Navigator software, but to no avail.
The solution seems rudimentary considering all the recent improvements in software and on network devices. The only solution that I have gotten to work is to connect the scanner directly to my Mac Mini via a USB port. In addition, the Canon MP Navigation software doesn’t seem to be scanning. I ended up using the Scanner software that comes with the Mac OS.
