Experience Better Sound in Linux with the Asus Xonar DX Sound Card

πŸ“… January 13, 2017
coverSo, you have finally constructed your ultimate tower of silicon greatness featuring quad SLI, NVMe storage, 4TB SSD data, 4K monitors, the latest multi-core CPU, maxed out RAM, and…what? You’re still using motherboard audio? You poor thing. Let’s fix that.

This article looks at the Asus Xonar DX PCIe sound card running in Linux and compares it with existing motherboard audio featuring the ALC1150, which is found on most higher-end motherboards these days.

Is there a difference in sound quality between a dedicated sound card and motherboard audio? Here are my tests and opinions from using the two myself.

Adding USB 3.1 to Linux

πŸ“… January 10, 2017
coverLinux supports USB 3.1 in the kernel. Why not show Linux some love and give it the hardware to use?

‘Tis a pity, but USB 3.0 is slow. Well, slow compared to SATA 6Gbps and the blazing fast M.2 NVMe. USB 3.0 tops out at ~440 MBps for external SSDs while SATA maxes out at ~540 MBps…depending upon the quality of the SSD.

Let’s go faster!

That is what USB 3.1 is for. The best part is that the prices have fallen, and you do not have to wait for future USB 3.1 motherboards. If you are running Linux, then you can add USB 3.1 to your existing system now. Even if your motherboard is an older model that only supports USB 3.0 and PCI Express 2.0, you can install inexpensive PCIe USB 3.1 cards to provide the faster ports and reap the benefits.

This article looks at the QICENT Dual-port USB 3.1 PCIe card and tests its performance on two different motherboards with PCIe 3.0 and PCIe 2.0.

Link Aggregation in Linux Mint 18.1 and Xubuntu 16.04

πŸ“… January 7, 2017
coverDo you have a few spare network interface cards?

Want to increase your local network throughput and handle more traffic?

Link aggregation, or bonding, is a technique that combines two or more network interface cards (NICs) into a single virtual network interface for greater throughput.

For example, two gigabit NICs result in 2 Gbps throughput. Three gigabit NICs allow 3 Gbps throughput. Four allow 4 Gbps, and so on. While these are theoretical maximum values and other factors affect network transfer rates, the point is that multiple network cards acting as a single “card” can transfer more data at a time. As an example, more users can access the same server simultaneously without seeing any noticeable drop in transfer speeds.

Linux supports link aggregation out of the box with only a few modifications. Regular, inexpensive network cards and switches can be used, so there is no need to purchase expensive, specialized hardware. This allows you to reuse existing hardware that you might already have on hand. And yes, it works well.

While link aggregation has worked in the past, newer Linux distributions tend to change a few things, so older setup techniques need revision.Β This is the case with Linux Mint 18.1. For details regarding the benefits of link aggregation, please have a look at the article describing link aggregation in Linux Mint 17 and Xubuntu 14.04Β (July 12, 2014). The information is still relevant.

Link aggregation works well in Linux Mint 18.1, but a few changes are needed in order to make it work. However, it is easier than expected!

Software – A Better Software Manager for Linux Mint

πŸ“… December 23, 2016
coverLinux Mint is a superb operating system, but its default software manager is rather lacking. WeΒ can install a better software manager that looks sleeker and is easier to navigate than Linux Mint’s Software Manager.

This article shows how to install the gnome-software program, which is the same user-friendly software manager seen in Ubuntu and Xubuntu. Yes, we can use it in Linux Mint.

i7z – What Is Your i7/i5/i3 CPU Doing?

πŸ“… December 20, 2016
coverAre you pondering important life questions, such as, “What is the temperature and current frequency of my Core i7 CPU?”

“I have no idea what C0/C1/C3/C6/C7 states are, but I sure want to know how much time my CPU spends in them.”

“What is the stepping, model, and family info of my i7 CPU? Are we related in some way?”

Well, ponder no longer because the command line program i7z (a reporting tool for Intel i7/i5/i3 processors) will answer those questions for you in real time. And if that is not enough, information can be logged to a log file for serious analysis later.
