I am still amazed at how powerful this little unit is. I got the Beelink Gemini X45 Premium Mini PC (6GB/128GB). Multi-boot Windows 10 and Ubuntu 18.10 setup. This unit has worked flawlessly from the moment I connected it. Windows 10 (Home) is installed with the unit. There was never a prompt to enter an activation code (pre-activated). I updated to the latest version (1809) in November 2018 just fine. This Mini PC has a fan inside the unit, which I cannot normally hear. I don’t know if that’s because it’s off or running so slow. However, sometimes I can faintly hear this little fanRead More →

The cAP ac is a very capable and powerful wireless access point that looks beautiful on both walls and ceilings. The concurrent dual band wireless radio supports dual chain 2 GHz 802.11b/g/n and 5 GHz in a/n/ас standards, and will provide coverage in 360 degrees around it. Even though the radio supports repeater mode, the two Ethernet ports give you the ability to extend your network with cables, even if PoE power is required, since the cAP ac supports 802.3af/at PoE input on the first port, and passive PoE output on the second port. Device supports IPsec hardware acceleration too. – cAP ac (International) supportsRead More →

The perfect android TV box to watch YouTube, Netflix, and 4K videos. It is low priced, Google and Netflix certified, Voice Search remote, Google Cast and low power consumption. This is an excellent value device if you mostly watch Netflix, Youtube and Google Play Movies/TV. It’s well worth purchasing also if you are inclined to install KODI on it as a media player. Watching various TV shows and movies using the Android TV Netflix app is an excellent experience. Connecting my laptop to the TV via HDMI was my previous messy solution for watching movies and media content. In comparison the Mi Box is muchRead More →

Since Ubuntu code names are in incremental alphabetical order, we now have Cosmic Cuttlefish after Ubuntu 18.04 Bionic Beaver. Ubuntu 18.10 will be released on 18th October 2018. Ubuntu 18.10 release schedule will be different from previous releases. Unlike the previous releases, there will be no alpha or beta milestones. This will be replaced by ‘testing weeks’. 1. GNOME 3.30 Most of the visual and under the hood changes in GNOME 3.30 will be seen in Ubuntu 18.10 as well. 2. New default theme Ubuntu 18.04 was supposed to have a new look with the community developed Communitheme. This theme could not be completed inRead More →

On 5GHz WiFi there are more channels and less interference, both are important for fast wireless communications. The bandwidth can even be increased multifold by combining channels. 5GHz was introduced in 802.11a, but the radios were expensive and the band didn’t gain popularity. 802.11n was defined for both 2.4GHz and 5GHz bands, which finally launched 5GHz use. The latest 802.11ac is only defined for 5GHz but all devices still support 802.11n and most also on 2.4GHz Channels The 5GHz band is divided into 5MHz channels like the 2.4GHz band. Fortunately only every fourth channel (36, 40, 44…) is used which provides for de facto 20MHzRead More →
