Welcome back to Codeaholics! We will kickstart our 2026 collaborating with ExpressVPN! **Talk#1: The Pain of Processing PDFs** by **Angus Cheng** Reading PDFs is very difficult, here's what I've learnt over the last five years running a SaaS that processes PDFs **Talk#2: Why does ExpressVPN switch from C to Rust for Lightway’s code?** by **Thomas Leong** We built Lightway from scratch in a quest to offer a VPN protocol that serves the needs of VPN users in a modern, mobile world—one that’s fast, secure, and reliable. Since launching Lightway five years ago, we’ve had it open-sourced and audited, as well as implementing key upgrades. We have just rolled out a new version of Lightway to users—one that sees our pioneering VPN protocol rewritten in Rust programming language. For this technical talk, we wanted to take a moment to discuss some of the more technical reasons behind the changes we’ve made and dive into the benefits of Rust over C, the language we originally used for Lightway code.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Join us as we get together to see SIRAT, an Oscar-nominated Best International Film from Spain that follows a father, accompanied by his son, goes looking for his missing daughter in North Africa. Here’s a description, trailer and our plan for this event: DESCRIPTION: A father, accompanied by his son arrive at a rave deep in the mountains of southern Morocco while searching for his daughter who vanished months ago at one of these endless, sleepless parties. As their search continues, the journey forces them to confront their own limits. The film is directed by Oliver Laxe and stars Sergi Lopez, Bruno Nunez Arjona and Richard Bellamy. TRAILER: https://www.youtube.com/watch?v=ww-IXHXvS70 BUZZ & ACCLAIM: SIRAT has already won numerous awards, including 4 at the 2025 Cannes Film Festival, along with the Chicago, Montclair and Toronto International Film Festivals! It also earned a whopping 11 nominations at the 40th Goya Awards, including Best Film and Director, and was nominated for Best International Feature Film and Best Sound at this year’s Academy Awards. The film is earning a stellar 92% positive rating on Rotten Tomatoes which calls it “an unforgettable exercise in tension” and “a brutal reminder that the journey can be more important than the destination.” PLAN: We’ll plan for a 7pm-ish showing and will confirm/announce details as the date gets closer. Once showtime is confirmed, advance purchase (via GFC website preferred) is advised! Once you have your ticket, please list your seat number in the Comments section of this event. PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! Look forward to seeing you there, Dan
