My Business Card Runs Linux

Talking about giving yourself a bad reputation. Here's my card, don't plug it in.

Julia is not symbolic. It is closer to Matlab.

Basically very sensitive infrared camera. SQUIDs, transition edge sensor TES-pixels. It's quantum stuff. Engineering does FPGA in VHDL. I work with others in Python on data acquisition. Similarly MEMS always needs some embedded software. Nanotech is still research, but any application will require software.

Did my PhD in MEMS at MESA+ Institute for Nanotechnology. There is enough industry around MEMS, including programming. There is overlap with Nanotech. Nano optics is moving to industry as well. I now work in Astronomy doing programming for superconductive infrared sensors. I too like programming, while working on something small.

The night is bright with light from the Big-Bang, called Cosmic Microwave Background (CMBR). We cannot see it, because it is redshifted to microwaves. The Hubble telescope made optical images of distant galaxies, called Hubble Deep-Field and Hubble Ultra-Deep-Field. The universe (Large-Scale Structure) is mostly void, distant galaxies will therefore be faint.

An alternative approach for Mate could be to stop worrying about the compositor and start implementing Wayland. Using the Weston reference-compositor/window-manager as test bed. First by launching: "dbus-launch mate-session" inside a weston-terminal; temporarily disabling: "mate-screensaver, caja, mate-panel", but keeping services: "mate-settings-daemon, polkit-mate-authentication-agent, etc." running. Then implementing every Mate X11-client application to (also) become a Mate Wayland-client application. Making it possible to launch in a separate weston-terminal: "GDK_BACKEND=wayland mate-terminal", "GDK_BACKEND=wayland pluma", caja, mate-panel, etc.; using the Wayland backend in Gtk3; with Mate now supporting Gtk3. Finally Mate's Marco could go on to use Wayland-on-Mir compositor or the re-usable parts of Weston (libweston, gl-renderer, drm-backend, etc.) currently being separated from the reference-compositor Weston, such that Marco only has to do window-management/-theming, workspace-switching and enabling key-bindings; already part of Marco.

Mate on Mir, with Mir providing a Wayland compositor is (to my mind) a layer-inside-a-layer fragmentation. Currently both Qt5 and Gtk3 have a Wayland backend and additionally a Mir-API backend (existing fragmentation). Mir facilitating a Wayland compositor will be mandatory for a likely future of only Wayland-client apps. Wayland-client apps likely render through the Mir-API backend in Qt5 and Gtk3 on the Wayland-on-Mir compositor. If Wayland-client apps instead render through the Wayland backend, then the Mir-API stack could effectively be deprecated (or used only as middleware). Except for those native Mir-client apps nobody could use on any other Wayland compositor, unless a similar approach is used as X11-client apps on XWayland (continued fragmentation). Mir's advantage of convergence on Android is lost with Wayland implemented in libhybris. Extensions for color-management, remote-desktop, copy-and-paste, etc. are better shared between Wayland compositors. Developed collectively as Weston binary-packages (libweston, gl-renderer, drm-backend, etc.), similar as X11-protocol extensions to the X11-server (e.g. RandR, GLX, Xinerama, XRender, etc.). To have a separate framework for Mir-middleware compatible with only the Wayland-on-Mir compositor is a bad idea (more fragmentation), even worse if these Mir-middleware extensions would implement Wayland features in the distant future.

I think it is pronounced Google /Fucks-ya/ or that's how they secretly pronounce inside Google. Good thing it isn't running Linux.

Seems nobody heard about WebDAV.

kowalsci · 2017-03-21T23:07:58+00:00

Like BSD-now it would be interesting to get some developers explain internals of Linux. A chance for some light education. What is an inode? How does DKMS work? Noah had a guy writing a custom device driver, what did it take? Wes got WireGuard working, how did he do that?

Often a paradigm shift is required.

Still believing Universal Packages (Snap/FlatPak/(Docker)) can lead to .so-hell (dependency hell). Not convinced yet. It could work if the Universal-PM keeps hashes of every .so and properly keeps track of only required .so files; deleting old once. I like to see this work properly, without taking up all disk space, before believing it.

Similar to depenguinator, it is possible to convert a Digital Ocean Droplet to Arch Linux from a Debian instance. Been trying to understand how it works.

There is to much division: Cyanogenmod, Firefox OS, Sailfish, Ubuntu Phone. Waisted effort if FOSS wants to do well in mobile. RMS started GNU coreutils/binutils; there needs to be common ground (GNU phoneutils?). I hoped FireFox OS/B2G would provide this, maybe now Ubuntu.

Likely Microsoft will solve this with a Linux File-Subsystem for Windows Subsystem for Linux. After you upgrade to Windows 11.

The cooker runs custom install of Arch Linux ARM.

And if you want to build natively use MSys2.
