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.

Join us for dinner and discussion about queer books! For our next book, we will be reading **‘Sisters of the Vast Black’** by **Lina Rather**. **Blurb** **The sisters of the Order of Saint Rita captain their living ship into the reaches of space in Lina Rather's debut novella, *Sisters of the Vast Black*.** **Blurb** Years ago, Old Earth sent forth sisters and brothers into the vast dark of the prodigal colonies armed only with crucifixes and iron faith. Now, the sisters of the Order of Saint Rita are on an interstellar mission of mercy aboard Our Lady of Impossible Constellations, a living, breathing ship which seems determined to develop a will of its own. When the order receives a distress call from a newly-formed colony, the sisters discover that the bodies and souls in their care—and that of the galactic diaspora—are in danger. And not from void beyond, but from the nascent Central Governance and the Church itself. **The Plan** 19:30 Meeting @ the restaurant 19:45 Dinner & discussion 21:15 Choosing a book for April 21:30 End **Dinner** The name of the restaurant will be announced in the WhatsApp group chat. **What to do** 1\.

**Wilderness of Mirrors** Wilderness of Mirrors lets you play a role in an elite team of secret agents tasked with a dangerous mission. First, we carefully plan how to pull it off, then we play it out to discover how brilliantly (or disastrously!) it unfolds. The more detailed and ambitious your plan, the more you risk complicating things for yourselves. Oh, and did we mention someone might be a traitor? Find out what blows up in a game of espionage, intrigue, and self-inflicted chaos. **Church of the Maw** Deep in the rural nowhere of North Carolina sits Devil King Hills, home of the highest rate of missing persons cases in the state. Somewhere in its suburbs lies the Church of the Maw, the last remnants of now-extinct Cult of the Maw that was supposed to have been eradicated decades ago. But the Bureau is pretty sure that they're trying to summon something sinister and eldritch. When an agent goes missing, your team is sent on a mission to either retrieve your colleague or wipe the Church out once and for all. **The Laughing Idol of Lar-Shann** For centuries the remote village of Pumriel has suffered the tyranny of the demon Lar-Shann, his bellowing idol and his power-mad acolytes. Now you are sent to Pumriel to retrieve a priceless bottle of locally-made brandy, but to find it you will have to venture into the demon's fortress-temple... A pulp-fantasy adventure using the *Doomslakers* system **The Allwinter Run** All is snow and quiet and spring has not come. For the animals of Dashen Forest, they awaken from hibernation to find no new growth, only ice. They cannot stay here. A game of Briar and Bramble, in which we find out if these critters can survive the elements and each other as they travel to a new home in a fantasy world. WHAT IS ONE-SHOT SATURDAY? It's a weekly meet-up in Sheung Wan/Central, focusing on indie games and single-session games (one-shots). 而家所有游戏係英文嘅但如果你要嚟玩中文游戏，我哋會無任歡迎。只要湊啱玩家就行！ You can drop in and play at any One-Shot Saturday – you do not need to have played in a previous session or commit to playing again. Whether you've played an RPG before or not, you're welcome to join us. Please arrive on time as once the games begin it becomes difficult to properly introduce latecomers. Join the conversation, make plans, suggest games to play, etc. — Facebook group: [https://www.facebook.com/groups/oneshotsaturdays/](https://www.facebook.com/groups/oneshotsaturdays/) \*\*\* WHAT IS A TABLETOP RPG? It's a game in which you never know where the next stop will be, because it’s all down to the decisions you and your fellow players make. Usually one person is the Game Master (or "GM"). Everyone else will be players, taking the role of the characters in the game. The players get to say what their characters say, think, and do. The GM describes everything else in the world. Then... we play to find out what happens. The game is a conversation: I say something, then you reply, maybe someone else chimes in. We talk about what's happening to the characters we imagine and the world around them. We also talk about the rules, which help us decide what happens next if the next step is in doubt. The rules differ from game to game: some use dice to shape the story, others use cards or something else. It's always a conversation, though.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

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.
