Steve Lembark has been playing with computers for thirty years as a SysAdmin, DBA, Programmer, and ETL analyst, Architect, and general beer drinker. He is a principle AT Workhorse Computing.His experience with shell programming started with DCL, since then he has survived batch, sh, ksh, and bash — hence the need for beer.Steve Lembark installed his first RH distribution on a 486 using floppies cut by Eric Troan in his garage, back when people told Eric he was an idiot for trying to make money off of something that was “free” to begin with. They also told Eric that nobody would use open source in a corporate environment, companies wanted something backed by a “real company” like IBM.Workhorse Computingmailto:lembark@wrkhors.com +1 888 359 3508

STLLUG - January 18, 2024

Design a detailed digital collage that captures the concept of big data and the Hadoop ecosystem. Center the image with a yellow elephant, surrounded by flowing streams of binary code and data packets. Include cloud icons and server rack graphics radiating out from the elephant, and scatter smaller logos of related technologies (like Apache Hive, Apache Spark, etc.) around. Add abstract elements like fading graphs, charts, and network diagrams in the background. Use a modern palette with shades of blue, green, and yellow on a subtle gradient or geometric background. Highlight key areas with soft glow or light streaks for a dynamic, futuristic feel. The image should be sized for blog headers (1200px x 675px) and saved in high-quality PNG or JPEG.

Hadoop for big data. An intro.

SLUUG - January 11, 2023

Design a sleek, dark-themed blog image. The background should display a subtle gradient from dark blue to black, with slight inclusions of a world map and a modern shield icon with a lock symbol for security representation. In the center, create an abstract image of a semi-transparent terminal window, slightly tilted, showcasing code snippets. On either side of the terminal window, include minimalist line-art styled icons inspired by communication and debugging tech tools. The left icon should match the terminal theme colors while the right icon can remain its recognizable blue yet blended well into the dark theme. Edge the image with scattered binary codes or data flow lines to add a high-tech feel. Note: the image should be high-resolution, clean, and without any text.

Why Use Linux: Advantages & Challenges

By: Stan Reichardt

STLLUG - July 21, 2022

Create an image that visually represents the concept of Filesystem in Userspace (FUSE) with a gradient background transitioning from dark to light, starting from a rich shade of blue or black at the top, transitioning to a lighter shade towards the bottom. The main visual should be a graphic representation of a filesystem extending from a user's desktop or laptop, with connected icons symbolizing different types of storage services such as a locked folder for encrypted filesystems like `encfs`, a cloud for cloud storage, and a server icon for `sshfs`. Include the Linux Tux penguin near the bottom of the screen or next to a silhouette of a user represented as a hobbyist or business professional interacting with the filesystem. Also, include minimalist icons that represent FUSE features like `sshfs` and `encfs`, and a terminal icon with a simple command prompt interface to represent user's ease of use.

Filesystem in Userspace (FUSE)

STLLUG - April 21, 2022

Create an image with a dark gradient background transitioning from deep navy blue at the top to black at the bottom. The central focus is a large, transparent schematic of a motherboard with RAM modules. On the left side of the motherboard, include the Tux penguin logo which is the mascot for Linux. On the other side, place the logo of the Raku language, a programming language that succeeded Perl. Around the motherboard, incorporate small, clear icons and symbols representative of system calls and data structures, such as pointers, memory addresses, and fragments of binary code. Overlay a subtle, semi-transparent process tree diagram in the background. Accentuate the main elements with a faint, glowing outline, and use jagged lines or swirling paths to emphasis the image's overall complexity. The overall appearance should be clean, professional, and compelling, without unnecessary clutter.
