"Linux and CinePaint: OSS in Hollywood"

Linux is the #1 operating system in Hollywood feature film animation and visual effects, for both servers and desktops. Why are Disney, DreamWorks, ILM, Pixar, and Sony running on Linux? Note that the studios' filmmaker tools running on Linux are proprietary -- except one. CinePaint is used to retouch films such as Harry Potter and Spider-Man. It was used to add flying arrows in The Last Samurai. For 2006 CinePaint has a totally new architecture based on FLTK, a fast free portable GUI API contributed by the film industry. What's new in CinePaint and what does it mean for users outside the film industry?

In January, Chris Smith posted an idea he had to the lula mailing list: anyone interested in forming our own UML hosting co-op? People were interested and the LA UML Co-Op came into existence.

LA UML co-op members David Benjamin, Michael Fair, Shane Chen, Steve Redlich, and Chris Smith will lead a panel discussion on what UML offers; how the co-op was started, the hardware spec'ed and purchased, the colocation ISP selected; and resource sharing and legal issues. As the co-op's server is not yet installed at the ISP, the plan is to bring the server to the meeting for a realtime demonstration of UML in action.

"Previously GNU Compiler Collection (GCC) performed optimization in the low-level Register Transfer Language (RTL) intermediate representation. Implementing high-level compiler optimizations such as vectorization and parallelization in the RTL intermediate representation is awkward or impossible.

"The Tree Static Single Assignment (SSA) infrastructure in GCC provides an ideal framework to provide advanced optimizations. Tree SSA provides a language independent infrastructure that allows C, C++, and Java compilers to make uses of a common library of optimizations. This talk will provide an overview of Tree SSA in GCC, the performance benefits of Tree SSA for developers using GCC, and future plans for Tree SSA.":

"Probably the most vexing problem facing networks today is reconciling the asynchronous nature of almost all traffic at the edge of the net with the almost universally used synchronous transport used on land lines, and synchronous carrier in wireless and satellite networks. Distributed Queue Switch Architecture (DQSA) is based on what can be described as a close to ideal MAC (medium access control) that enables the efficient sharing of a common channel by multiple nodes over any distance and at any speed. The attached nodes can generate both bursty packet traffic and traffic that requires the equivalent of TDM-like channels.

"DQSA can operate in every physical medium in virtually all network environments: LANs, MANs, SANs, WANs, wireless and satellite networks. DQSA makes possible the implementation of a nation-wide WAN without routers.

"Three demonstration systems have been built using 10 Mbps copper, T1, and 200 Mbps passive fiber. All the demonstration systems utilized Linux using drivers that made the underlying DQSA network appear as conventional Ethernet.

"This talk describes the underlying DQSA technology and presents an overview of the potential of DQSA. Amongst the potential applications that will be discussed is one using DQSA as the switching mechanism in a Beowulf/Linux cluster. DQSA makes possible cluster sizes in the hundreds or thousands at a cost that rises linearly and with little increase in latency."

There will be plenty of time for other topics so bring your questions--or your presentations--for the last meeting of the year.

After that we have the good fortune to have Al Danial back. He will be taking us on a tour of Cygwin, a Linux-like environment for Windows, running on his Sony TR1A laptop (dual boot with a fresh install of Knoppix).

For more detailed information about Linux in the LA area please see Dan Kegel's excellent site.

Please also note that On November 22nd, 2003 at the Los Angeles Convention Center, the USC, UCLA, and Simi-Conejo Linux Users Groups present the second annual Southern California Linux Expo . If there are at least 10 individuals going we will qualify for a group rate of $26/person otherwise it will be $65 per person. You can contact me ibk@cyberverse.com for more information.

His second talk is about the genetic algorithm, a technique for finding optimal solutions to problems in fields as diverse as mathematics, biology, physics, and engineering. Genetic algorithms are easy to understand and easy to implement. Best of all, they are embarrassingly parallel and thus run extremely well on Beowulf clusters. Al will demonstrate the evolution of an optimal solution in real time.

Update: code for the examples shown during the GA talk.

The complexity of hardware and software makes it difficult to identify performance problems on computer systems. There can be unexpected interactions between the various software and hardware components that developers are unable to predict. Thus, performance monitoring tools such as OProfile are essential for identifying these performance problems, allowing the programmers to address the problems.

OProfile is a low-overhead, system-wide profiling tool that uses the processor's performance monitoring hardware to characterize programs running on Linux systems. On IA32 processors such as the Intel Pentium III OProfile can indicate which sections of a program have frequent cache misses and pipeline stalls. This talk will demonstrate data collection and tuning techniques with OProfile.

"The MySQL database server embodies an ingenious software architecture that maximises speed and customisability. Extensive reuse of pieces of code within the software and an ambition to produce minimalistic but functionally rich features have resulted in a database management system unmatched in speed, compactness, stability and ease of deployment. The unique separation of the core server from the table handler makes it possible to run MySQL under strict transaction control or with ultrafast transactionless disk access, whichever is most appropriate for the situation."

Mr. Greant is very active in MySQL and PHP development. His book, Php Functions Essential Reference is well known in the PHP development community. We are most pleased that he has kindly arranged to present 3 topics:

An Introduction to MySQL and PHP (45 min)

Advanced Development with Apache, MySQL and PHP (3 hours or so)

The Devil and the Penguin: Open Source/Free Licensing in a Proprietary World (45 minutes)

"Businesses and universities are hiring people with Linux skills, deploying Linux on servers to save money, and even evaluating Linux on the desktop. Microsoft's pricing and security policies have made Linux an attractive alternative. Linux's open source nature makes it an excellent tool for teaching. Linux now comes with free alternatives to Internet Explorer and Microsoft Office which work well enough for the average user. University IT departments should start planning to support Linux on the desktop in recognition of its increased importance."

"Multi-Domain means virtual hosting multiple domains on the same server (this will be single IP virtual hosting and will not cover 1 IP per domain installation) Black Box means that adding email users does not involve adding system users. Spam sorting means that whatever Spam Assassin labels Spam gets put into a Spam folder. Secure SMTP relay means that you can use the same SMTP server provided by the domain instead of having to rely on the local ISP or "Receive before Send" methods. IMAP means that the system is designed to store all mail on the server.

The tools used to implement it are: Postfix, Spam Assassin, Cyrus IMAP, OpenSSL, and SASL v2 To support virtual domains userids will be of the form "user@domain.dom". While one could use Kerberos with this system, I will not be doing that.

The installation server will be Debain Woody (now Debian Stable). We will be using packages from unstable. Namely the cyrus21 and libsasl2 family of packages. We will need to recompile Postfix for use with SASL2 or we will use the packages I compiled for my server.

Mail will come into the system through Postfix which will hand it off to another script that will run it through Spam Assasin. That second script will use LMTP to deliver the mail for final delivery to the Cyrus system."

"But I don't like SPAM!"   --Monty Python

For many people, unsolicited emails pushing everything from herbal viagra to mail order brides are becoming an increasing annoyance. Simple filters used to take care of most of the problems, but required active updating. SpamAssassin is a different approach using a threshold scheme which often requires no user modification to get great results. This talk will focus on how SpamAssassin works, and (more importantly) how you can use it to filter out unwanted junk from your mailbox.

The discussion will include issues of management, scalability, fault tolerance, load balancing, and the "automatic restore" capabilities of these systems. They use RAID 5 within clusters and RAID 1 across clusters, with a nice browser based management interface. All running nice and smoothly thanks to power and technological excellence of Linux.

He will also deploy a 4 node cluster connected via two high speed switches. You will be encouraged to connect to the network and pound away at NFS and SMB shares, test the configuration tools and get an idea of the capabilities of these systems.

There will also be the usual deployment of the DHCP based Internet drops, so please bring your laptops/hardware along and plug in. We can expect to have lots of time on Saturday after the presentation to break out into individual work-group SIGs.

For our main presentation, Lilax is pleased to host William Cohen, GCC Enginerd at Red Hat, Inc., for his second annual presentation to our group. Here's the abstract for his talk:

Linux provides a preemptive multitasking environment with powerful software development tools that many programmers are familiar with. Increased performance in hand-held devices has made it feasible to use the Linux operating system in these small devices. Due to the typical hand-held device's significant differences from workstations, alternative techniques are required to install Linux on a hand-held system and to develop useful applications. This talk will describe the development environment required to generate Linux and the associated software for a hand-held device, typical limitations of the devices, and techniques to install Linux on a hand-held device.

While Frank is a relative newcomer to the tape storage world, he is an old hand at open systems and high-performance computing. In 1987, while at Avery, he orchestrated the transition from DEC VAX to multi-vendor Unix for the company's Engineering Computation Network, and he led the development of client/server applications for engineering computation and visualization.

Frank had his introduction to Linux in 1996, while working as Web Marketing Manager for Visual Numerics Inc.(VNI) in Boulder, CO. His Web development team used Linux on Macintosh PowerPC computers as a development and staging platform for the company's websites, hosted on Solaris. He has been a Linux fan ever since.

Frank holds a PhD from the University of Wisconsin and a BS from the University of Utah. Frank's presentation will give an overview of tape backup technologies, products, and strategies, with a special emphasis on VXA technology and its advantages for Linux users.

This will be followed by a technical presentation of the important new capabilities SGI is adding to the Open Source movement.

Charlie Bryant from SGI will discuss important new capabilities SGI is adding to the Open Source movement - including asynchronous I/O, big memory support (>1 GB), 64-bit journaled file system (xfs), kernel debugging (kdb), performance monitoring (performance co-pilot) - and their impact on 3rd party applications and performance. He'll also be showcasing the 1400L server.
