So the Linux Foundation just announced a new online course for Linux System Adminstration, including a certification exam.

Do some people register for these kinds of courses and pay the fee out of their own pocket, or are these typically paid by an employer? I would love to take that course, but that price tag is just way too high for me as a college student, it even seems quite high for anyone to be honest.

Are there any similar materials to those of this course that are available for free (without the certification exam)?

I was troubleshooting very poor connectivity issues with my Wi-Fi card today and was testing different versions of firmware to see if they corrected the problem. First, I checked dmesg and saw that the firmware that was being used was a few version behind the latest one posted on wireless.kernel.org. I pulled down a newer firmware for my Intel (iwlwifi) card and placed it /lib/firmware. I rebooted, checked dmesg, and saw that it loaded the new firmware--great! Later today, I noticed that a new kernel was available via pacman, and since I wasn't sure how firmware updates on Arch (or any distro) work, I decided to remove the firmware I manually downloaded (I have no idea if the new kernel would have also included firmware, this was purely precautionary). Again, I checked dmesg after the reboot. Here is what I found.

iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7260-10.ucode failed with error -2 iwlwifi 0000:03:00.0: loaded firmware version 25.228.9.0 op_mode iwlmvm

What dictates which firmware is supposed to load? I have other (older) iwlwifi firmwares in /lib/firmware but they weren't loaded. Where did the version 25 firmware come from? This is newer than any iwlifi firmware I have seen and it's not in /lib/firmware.

A column from back in 2010 that outlines some of why Flash sucks. I'm posting it here in honor of YouTube dumping Flash for HTML5. It took a long time, but it finally happened.

The git version of mpv can provide interpolation to videos as the SVP project for Windows.

Here, it's explained, look for smoothmotion in the opengl section.

I'm running Elementary OS so I installed this PPA which also has the feature.

Just edit or add the following line in the mpv.conf

vo=opengl:smoothmotion:smoothmotion-threshold=0.0

You can also add use opengl-hq but my system works better with opengl alone.
