Sean Twiehaus started his career as a Field Service Technician. After being introduced to Linux in 2014, he got a little bit obsessed. By 2015 he was working as a System Administrator. During his time as an Administrator he focused primarily on automation using shell scripting and Ansible. Nowadays Sean is working as a Software Developer but he still remembers his command line kung-fu.

If you mention dotfiles, vimrc, or modern CLI tools, you can expect Sean to ask a million and one follow up questions about your config. You have been warned!

SLUUG - September 11, 2024

Create a tech-themed image that beautifully blends professionalism and modernism. In the core focus, generate two distinct, non-specific tech professionals standing beside each other with a subtle binary code pattern in the background to reflect their technological brilliance. On top, centrally place a friendly penguin to symbolize Linux. Surround it with symbols like a lock or shield signifying security, a small conference logo, a logo representing a popular version control system, and a small microphone icon near the central figures for speeches. To intertwine these elements, create thin, glowing circuit lines spreading from the central figures and logos, forming a network pattern to reflect the interconnected world of technology. Utilize hues of dark blue, white, with delicate accents of yellow or light orange to convey intellect, trust, and innovation. This image represents the anticipation and richness of an upcoming presentation on Linux, open-source security, and other related themes.

SLUUG - April 10, 2024

Create a high-resolution, tech-forward image that is 1200x600 px. On the left, occupying 40% of the image is a high-quality screenshot of a generic, professional webpage with headers, paragraphs, and images. Transitioning from this via a semi-transparent, gradient arrow (light blue to dark blue) curving from top left to the bottom right is a window showing HTML/CSS code with syntax-highlighted text on a dark background. The arrow is surrounded by a subtle digital transformation effect to symbolize the AI-driven process converting the visual design into code. Towards the bottom left corner of the layout is the logo for OpenAI GPT-4 Vision and a user group logo (SLUUG). If available, an appropriate icon or logo for the 'Screenshot to Code' tool is placed in the bottom right corner. The background color of the image is a neutral light gray or off-white. The overall aesthetic should feel modern, clean, and line up with a sense of a professional educational resource.

STLLUG - March 21, 2024

Create a vibrant illustration that embodies themes of AI and open-source technology. The central focus should be a stylized depiction of a brain with neural network connections, signifying Large Language Models. The supporting images should include illustrations of private, local hardware such as a server rack, and AI icons like a robot head, cogwheels, and circuit board patterns. Also include open-source logos for Markdown, Jupyter, GitHub, and a general logo for machine learning frameworks, along with promotional symbols like megaphones and social media icons. The image should be set against a gradient background with modern, abstract shapes or soft lines in blues, greens, bright yellows, oranges, grays and whites. Elements should be arranged with the brain in the center, hardware and AI icons in the top corners, and promotional symbols and logos scattered in the bottom corners. The space should be filled with video-related icons and supporting logos, maintaining ample white space for a clean, uncluttered look.

SLUUG - January 10, 2024

Generate an image that represents the theme 'History of the Shell.' The background should be a dark, textured terminal screen with a gradient to resemble a classic command-line interface. Position a timeline path across the image, indicating different historical milestones. Along this timeline, place iconic illustrations of historic computers and shell types such as an old IBM mainframe, a vintage UNIX system, and various old terminals. Insert the logos for MULTICS, GE GECOS, and IBM at appropriate points on the timeline, with each logo receiving a subtle glow effect. At the end of the timeline, depict a modern computer screen featuring a terminal window with a Bash shell prompt. Subtle glow effects and color accents using greens for terminal input text and amber for the old terminals should be applied. Ensure that there are no superfluous words or letters, except for the necessary logos.

STLLUG - December 21, 2023

Design an image for a blog that captures the key technologies and concepts for an upcoming presentation. Start with a gradient background transitioning smoothly from dark blue to light blue to symbolize a shift from local to offsite backups. In the center, place a high-resolution image of the ODROID H3+ board. Surround this with the logos of the ZFS, Restic, and recognizable icons for Linux/Unix arranged in a circular fashion. Include subtle vector graphics illustrating the 3-2-1 Backup strategy near the top with three hard drive icons of varying sizes, two smaller distinctive storage media icons, and an offsite icon represented by a distant server or a cloud. On the side of the ODROID H3+, introduce geometric patterns or icons signifying data protection. Lastly, include small screen overlay icons in a corner to suggest a virtual and free-to-access orientation of the presentation. Make sure all elements are balanced and synchronized visually, thereby visually encapsulating the focus of the presentation.

SLUUG - December 13, 2023

Create an engaging tech-related blog image. The backdrop should be a sleek modern gradient blue and white, invoking an atmosphere of trust and professionalism. In the center, prominently place the Pandas logo (a friendly panda face), alongside the Python logo. Surround these with subtly incorporated elements for ETL and Machine Learning: icons of gears for ETL, bar charts, and line plots for EDA, and a small neural network diagram for ML. To the side, ensure the Asciinema logo (a terminal screen icon with a play button) is visible but does not overshadow the Pandas design. Perhaps near this, include small terminal session illustrations or a command line snippet. Indicate the Google Colab environment with a small cloud icon, possibly with an arrow pointing at it for an upload/download concept. Finally, balance these design elements, leaving enough whitespace to keep the design clean and approachable, and consider using light, translucent overlays to accentuate key logos.

SLUUG - February 8, 2023

Create a minimalist, technically-oriented image. The backdrop consists of a gradient blend transitioning from soft blue to white. In the center of the image place a large, open folder icon that represents dotfiles, with semi-transparent overlays of icons for typical files such as .bashrc, .vimrc, and .gitconfig. On the left side of the folder, place the YADM logo, and on the right side the Git logo, indicating their synonymous relationship, connected by arrows. Add subtle, dotted lines linking these logos to various dotfiles, suggesting syncing and alteration capabilities. Dispersed around the central folder, include small icons representing different operating systems like Linux Tux, BSD Daemon, to hint their use across different systems. Maintain original colors for YADM, Git, and system logos for authenticity, while arrows and dotted lines can be light grey or blue to keep the visual balance without overwhelming the key elements.

STLLUG - June 16, 2022

Create a split background image. The left half should have a light grey background, and the right half a darker, modern shade of blue. On the left half, illustrating a retro-style Caucasian sysadmin with a laptop amidst command line interfaces, snippets of code, and a server or VM icon. On the right half, illustrating a sleek, modern Black automation engineer with a laptop that displays the Ansible logo. Also, incorporate playbook and gear icons. In the center, include the Apache logo (feather) symbolizing the commonality between both methods. Add subtle VM icons, perhaps as small server racks or cloud icons, slightly above the split to symbolize their dual usage. The entire composition should balance both sides visually with a clear dividing line enhanced by a slight shadow or glow effect.
