  • Struggling With the Linux Secure Copy Command? Use This scp Example

    The scp command lets you copy a file efficiently between two different hosts. The syntax for scp reuses the syntax of cp, so it should feel familiar to most Linux users.

    The tricky bit with the scp command is that either source or destination may be remote i.e. a computer connected to another network, different from your local one. When specifying a file for copying, you’ll need to include details about the remote host as well. This includes its IP address and username.

  • Junichi Uekawa: Surrounding a region with Emacs lisp.

    Surrounding a region with Emacs lisp. I wanted to surround a region with HTML tags and here's what I learnt today. Specifying "r" in interactive gives two numbers, begin and end. When I want to obtain multiple kinds of values in interactive, I can use newlines to delimit. set-marker is an api to keep a marker at relative position even after edits, API needs making make-marker to create an empty marker first, and seems like the number of markers affects editing speed so the API is made to allow reuse of markers. After I got these going I could now write.

  • Junichi Uekawa: Setting wake-on-lan in Debian way.

    Setting wake-on-lan in Debian way. There's several ways that your network interfaces can be configured. The Debian way is to use ifup/ifdown. Make sure your network is configured with it by checking ifquery. nmcli d and networkctl list are NM and systemd equivalents of commands. After you know which one is managing your device you can go ahead and set up WoL configuration appropriately. Default Debian installation would probably start with a ifup/ifdown config.

  • DRM Driver Posted For AI Processing Unit - Initially Focused On Mediatek SoCs - Phoronix

    BayLibre developer Alexandre Bailon has posted a "request for comments" of a new open-source Direct Rendering Manager (DRM) driver for AI Processing Unit (APU) functionality. Initially the driver is catering to Mediatek SoCs with an AI co-processor but this DRM "APU" driver could be adapted to other hardware too. Alexandre Bailon sums up this DRM AI Processing Unit driver as "a DRM driver that implements communication between the CPU and an APU. This uses VirtIO buffer to exchange messages. For the data, we allocate a GEM object and map it using IOMMU to make it available to the APU. The driver is relatively generic, and should work with any SoC implementing hardware accelerator for AI if they use support remoteproc and VirtIO."
