Final Modification for X220 - Upgrading to Intel 7260 Wireless AC

This will be the last and final hardware modification I will be doing for my Thinkpad X220. Almost all aspects has been upgraded, except for the WIFI. I will be upgrading the wifi chip from Intel 6205N to Intel 7260 AC. I need this modification so that I can regain my bluetooth back after doing the internal USB mod. Intel 7260 AC is the last generation of Intel WIFI cards that is compatible with the X220. Succeeding generations are in a different form factor and they are physically incompatible.

Install and Configure BIND DNS for Domain Resolution and Adblocking

I am rebuilding my homelab environment and I’ve decided to start with the DNS server. DNS (domain name system) is critical, as its main purpose is to convert easy to understand hostnames into hard to memorize IP addresses. Without DNS, you have to know and memorize which IP address to connect to. Example, instead of typing google.com, you have to memorize and type in the IP address of google, which is 172.217.2.174.

Rebuilding My Homelab Environment

With the recent release of RHEL 8.0 Beta, I decided to break and rebuild my homelab environment. RHEL 8.0 will be a new beast to tackle and be familiar with, and since my RHCSA certficate is valid until Mar 2021, it will be a good way to practice and prepare when it comes to recertification. I also need to do this to refresh my knowledge and not be stagnant.

Using a 35 Dollar Laptop in 2018

I was able to snag a laptop for 35cad dollars (60cad including taxes and shipping) – a legendary Thinkpad X220. This laptop is from year 2011 and being a Thinkpad it is built like a tank and still functions OK up to this day. It is also legendary and well-known for it’s great 7-row layout keyboard. This is the last Thinkpad generation to use the 7-row keyboard layout, although they recently released a Thinkpad 25 Anniversary Edition with modern components and a 7-row keyboard. Most recent laptops are using chiclet keyboards, which for me is a downgrade as opposed to an upgrade. I’ve been wanting to get an X220 as my old one broke down due to water damage. Finally after months of waiting, something showed up for a good price and it’s too good to be true. Usually Thinkpad X220s are in the price of 200cad, there must be a catch somewhere!

Building Android from Source

I’ve always wanted to build Android from source, and yesterday I was able to do so! It’s a complicated process, requires a lot of reading, patience, fast internet connection, a decent computer and lots of hours.

But why do all of this? I use my smartphone much like a portable computer nowadays. Connect to my voip server, make online purchases, do online banking, buy stocks, check emails, access social media, watch videos, listen to music, take photos, store lots of information, and send / receive calls and SMS.

Messing Around with a PlayStation2 (PS2) in 2018

About a month ago, we found a nice little PlayStation2 (PS2) in the curb in our neighborhood. Looks like nobody wanted it as it’s already afternoon and no one picked it up yet. I am hesitant to pick it up, as it contains no cables, no connectors, no gamepads. Just the PS2 itself.

So I decided to pick it up and planned my way on how to make it work without spending too much on accessories.

Using Logitech MK530 in Fedora Linux

My wired DELL Multimedia keyboard started acting up and several keys just stopped working. Rebooting my computer did not help. I thought it is just my Linux install but even if I boot to Windows 7, the keyboard is still misbehaving. Based on that troubleshooting, I have decided to get a new keyboard. After reading and comparing several reviews, I have decided for a Logitech MK530 combo – it is a wireless Logitech K520 keyboard and wireless Logitech M510 mouse. It also uses a unifying USB receiver – only 1 receiver and it controls both the wireless mouse and keyboard, and you can use upto 6 devices with just 1 receiver. Installing it in Fedora Linux is also a snap!
