Interview: Lennart Poettering (systemd).

Lennart Poettering (born October 15, 1980) is a German computer free software programmer known for his work on PulseAudio, a sound server, systemd, a replacement for the System V init daemon, and Avahi, an implementation of the zeroconf protocol for network device discovery.

Could you briefly introduce yourself?

I am Lennart Poettering, I work for Red Hat, as part of the desktop group. I wrote most of Avahi and PulseAudio, among other stuff. Right now I am focusing on systemd which I created together with Kay Sievers from SUSE. Systemd is a new system and service manager for Linux which is currently being adopted as init system by most major distributions.

What will your talk be about, exactly?

Well, systemd! The exact contents of my talk depends on what the audience wants to hear. ;-)

Systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts.

Systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux cgroups, supports snapshotting and restoring of the system state, maintains mount and automount points and implements an elaborate transactional dependency-based service control logic. It can work as a drop-in replacement for sysvinit. For more information, watch the video at http://www.youtube.com/watch?v=TyMLi8QF6sw

For system administrators.
System administrators can visit this page, to understand how to use the native systemctl calls that replace their old workflow in SysVinit. Note that the service and chkconfig commands will continue to work as expected in the systemd world.

GCompris: Introduction, Minimal Configuration & Installation.

Introduction

GCompris is a completely free educational software suite which contains a wide range of activities. It offers various activities aimed at covering a variety of fields such as the functioning of the computer, using the mouse and keyboard, general learning, reading, writing, foreign languages, algebra, as well as various activities such as memory and logic games, scientific experiments etc.

In GCompris you will find many individual software packages which together make up the complete GCompris suite of activities. Unfortunately, it is difficult to follow and maintain them as each one offers different graphic interfaces which vary widely in quality.

The purpose of GCompris is to provide a development platform for educational activities.

GCompris is part of GNU project and is placed under the GPL license.

RawTherapee cross-platform raw image processing program: a color-managed Linux workflow (Chapter II).

The default illuminant is D50; D55, or 5500°K, is not provided as an option.  The spectral data in Argyll’s own custom spectrum file, D50_1.0.sp, can be found in Measuring Colour, Fourth Edition [PDF] by R.W.G. Hunt and M.R. Pointer, conveniently accompanied by the values for D55. 

I used the latter to create D55_1.0.sp.  (Note, page 358 contains a typo; the middle columns for wavelengths 785+ are misaligned, and should be under D50, D55, D65, and D75.)

One more step remains before using the profile for high-quality work:  determining output levels as described on the BTDZS workflow page.

For printing real images, the only differences are that the image will have an embedded working space profile, and we set the printer profile in the color management dialog.  (I also set the soft-proofing display mode.)  Everything else stays the same.

PhotoPrint settings for actual printing:

rawtherapee -photoprint 0.4.2-pre2

RawTherapee cross-platform raw image processing program: a color-managed Linux workflow (Chapter I).

Partly out of curiosity, and partly to help widen the horizon of digital photography, I have worked through a color management workflow entirely in Linux, from raw photo to monitor to print.  It is actually a continuation of my page on zone system calibration in linux.  I must admit that the results were more a “proof of concept” than an ideal workflow, partly because of available alternatives, and partly because of limitations on my own ability to print in Linux.

Operating system:  Korora 20, 64-bit.  Korora is a Fedora remix that includes third-party and proprietary software that makes it easier to use out-of-the-box than Fedora, while retaining the “bleeding edge,” “state-of-the-art” qualities of the latter.  The applications below were all installed from the repositories, except for TurboPrint which was an .rpm download.

Color management application:  Argyll Color Management System 1.6.3, by Graeme Gill.  For Linux, there is no real alternative.  I mainly followed the tutorials on the Typical usage Scenarios and Examples page, together with the documentation for each individual program.

Raw converter/image editor:  RawTherapee 4.2.74.
