Slim Odd

[Desiderato Chouinard]

SLiMis an evolutionary simulation framework that combines a powerful engine for population genetic simulations with the capability of modeling arbitrarily complex evolutionary scenarios. Simulations are configured via the integrated Eidos scripting language that allows interactive control over practically every aspect of the simulated evolutionary scenarios. The underlying individual-based simulation engine is highly optimized to enable modeling of entire chromosomes in large populations. We also provide a graphical user interface on macOS, Linux, and Windows, for easy simulation set-up, interactive runtime control, and dynamical visualization of simulation output.

For help with installation on all platforms, see chapter 2 of the SLiM manual. The macOS Installer above will install the slim command-line tool and the SLiMgui graphical development environment. On Linux platforms there may be an installer for your platform, or you can build from sources. On Windows, there is a pacman installer, or you can build from sources; you can also run SLiM on Windows natively or under the WSL.

Note that the source code archive provided above contains neither macOS specific code, nor the Xcode project for SLiM; it is intended for users on Linux and Windows. The complete sources including macOS files can be found on GitHub; you can get the sources for a tagged release, such as 4.2.2, or for the current development head.

We also provide a GitHub repository called SLiM-Extras with additional useful tidbits for users of SLiM, such as user-defined Eidos functions for performing some common tasks, and we welcome contributions to that repository from others.

With the SLiMgui graphical modeling environment (compatible with macOS, Linux, and Windows), you can visualize your simulation as it runs and examine its parameters in real-time, allowing for much easier simulation development.

2021 December 15: SLiM 3.7 is released! This is a major release, with tons of new stuff and several important bug fixes. It adds Windows as a supported platform. This upgrade is recommended for all users, but breaks backward compatibility in a couple of ways for some models.

2021 March 3: SLiM 3.6 is released! This is a major release, with many new features and several important bug fixes. This upgrade is strongly recommended for all users; version 3.5 should not be used due to two bugs that could cause incorrect model results.

2018 September 3: SLiM 3.1 is released! This version greatly improves the performance of spatial interactions, and provides improvements to tree-sequence recording, among other improvements and bug fixes.

2016 December 8: SLiM 2.2 is released! This is a major release with big performance improvements and several new features. See the new SLiM and Eidos manuals for current documentation. There are also release notes in the announcement on slim-announce.

2016 April 1: SLiM 2.0 is released! We are excited to announce SLiM 2.0, a new major release of the SLiM package. SLiM 2.0 adds scriptability with Eidos, and interactive simulation development using the SLiMgui application. We have put up a blog post with more details about the SLiM 2.0 release.

It can be useful to see how others are using SLiM; sometimes you can even download the actual SLiM model used in a paper. However, updating a list of all the publications that cite SLiM became too time-consuming, so now we provide links for Google Scholar searches, for papers that cite our SLiM papers.

SLiM is an acronym for Simple Login Manager. Lightweight and easily configurable, SLiM requires minimal dependencies, and none from the GNOME or KDE desktop environments. It therefore contributes towards a lightweight system for users that also like to use lightweight desktops such as Xfce, Openbox, and Fluxbox.

SLiM can automatically detect installed desktop environments and window managers through the use of sessiondir /usr/share/xsessions/ in /etc/slim.conf. Those upgrading from a version before 1.3.6-2 must amend /etc/slim.conf and xinitrc, accordingly. See below.

SLiM can be configured to automatically set a desired username, which will therefore already be completed. The password field will also already be focused by default. Change the following line in /etc/slim.conf:

Install the slim-themes package. The archlinux-themes-slim packages contains several different themes (slimthemes.png). Look in the directory of /usr/share/slim/themes to see the themes available. Enter the theme name on the current_theme line in /etc/slim.conf:

Additional theme packages can be found in the AUR. See the theme documentation for how to customize your theme or make your own. SLiM does not support alternative theme directories, so it is recommended to create a package for your custom theme so that pacman is aware of it.

The Xorg server generally picks up the DPI but if it does not you can specify it to SLiM. If you set the DPI with the argument -dpi 96 in /etc/X11/xinit/xserverrc it will not work with SLiM. To fix this change your slim.conf from:

To prevent VT switching whilst locked, set tty_lock to 1 in slimlock.conf. This also requires that that you have write access to /dev/console and that slimlock has the sys_sys_tty_config capability. One way to achieve this is set slimlock to suid root:

There is a bug or known issue with the combination of SLiM, Xfce and systemd that does not let the system to properly shutdown and systemd waits for the SLiM service to end, but eventually is terminated.

The Dapr CLI provides an option to initialize Dapr using slim init, without the default creation of a development environment with a dependency on Docker. To initialize Dapr with slim init, after installing the Dapr CLI, use the following command:

All of the same great features as the Strada Wireless in a thinner, lighter design that incorporates a larger screen and display! The slim sensor designed specifically for road bike use virtually disappears inside the fork.
