Motif 1.2.3 Runtime and Development System for Linux

The Motif toolkit has come to Linux. Dale reviews Sequioa International's Motif Toolkit for Linux.
Performance of mwm

I found mwm to perform very well on my system.

I did check its memory usage, and found that it used 1460KB of memory (according to TOP), while fvwm used only 296KB. Clearly, if you are trying to conserve memory, fvwm is the better way to go. As mentioned earlier, there is no virtual mwm, so if you like having a larger than screen desktop, you'll want to stick with fvwm. However, in terms of a solid consistent sharp look-and-feel, mwm has a slight edge.

fvwm in top:

67 dal   2  0  160  296 296  S  0.8  4.1
0:25 fvwm

mwm in top:

980 dal  3  0 344  1460 608  S  1.7 20.3
0:01 mwm

I was impressed by Sequoia's port of Motif for the Linux platform. They have done a fine job bringing the industry standard to Linux. If portability is a concern for you or you want to use the same tools as the rest of the industry, then I recommend this product.

[Ed: Since this review was written, GUI, Inc. has taken over responsibility for the SWiM Motif distribution, and has released a new version of SWiM based on Motif 1.2.4. GUI is responsible for support, including upgrades, for SWiM. More details will be available in the review of GUI's SWiM Motif 1.2.4 which will be published in a future issue of Linux Journal.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
