dmesg gets Human Readable Output

Many Linux command line tools, such as ls or du, have a “human” option to make it more readable by… humans. When you want to get the kernel log, to find otu potential problems, you’d usually run dmesg, which dump the complete log in one go and looks like: [    0.000000] Initializing cgroup subsys cpuset [    0.000000] Initializing cgroup subsys cpu [    0.000000] Initializing cgroup subsys cpuacct [    0.000000] Linux version 3.11.0-15-generic (buildd@roseapple) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu8) ) #25-Ubuntu SMP Thu Jan 30 17:22:01 UTC 2014 (Ubuntu 3.11.0-15.25-generic 3.11.10) [    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.11.0-15-generic root=UUID=9c042788-fa75-4fc4-9b12-598c809410e8 ro quiet splash [    0.000000] KERNEL supported cpus: [    0.000000]   Intel GenuineIntel [    0.000000]   AMD AuthenticAMD [    0.000000]   Centaur CentaurHauls [    0.000000] e820: BIOS-provided physical RAM map: [    0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009f7ff] usable [    0.000000] BIOS-e820: [mem 0x000000000009f800-0x000000000009ffff] reserved [    0.000000] BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved [    0.000000] BIOS-e820: [mem 0x0000000000100000-0x00000000bfd9ffff] usable [    0.000000] BIOS-e820: […]

How to Upload YouTube Videos with the Command Line in Linux

Like many people, I access Internet via an ADSL connection at home. ADSL stands for “Asymmetric Digital Subscriber Line”, with Asymmetric being the key word here, as it just mean your download speed will be (much) higher than your upload speed. My ISP promises a theoretical 10 Mbps download speed, and 512 Kbps upload speed, and this is pretty close in reality: Data Rate: 10240 (downstream), 509 (upstream) kbps.

If it’s a video you’ve shot yourself, and copied inside your computer, there’s very little you can do, except processing the video with tools such as HandBrake to make it smaller before upload. But if the video files are located somewhere in the Internet, and […]
