SUMMARY:Steve Bolman\, "Organism in Excel" or "Faking VBA to mock Functions as first class `Objects`"
DESCRIPTION:“Organism” is a dimensional analysis algorithm that over the past 20 years I have written in several languages (both FP and OOP paradigms). I decided 18 months ago to attempt to build it using VBA (inside Excel) and was surprised that in fact the hurdles presented by a language that remains fundamentally unchanged since the mid-90s could be overcome. To those not familiar with how Excel and VBA work together\, there were reasons I thought it was likely I would not get the results I had hoped for\, but with few exceptions I found workarounds. \nThis will not be a structured talk so I am happy to either discuss VBA in detail or focus on the product ‘Organism’\, what it does and why I feel it is important as an tool for global engineering. \nBio: Steve initially presented “Organism” written in Erlang to HFPUG over 10 years ago. A Chemical Engineer by training with 3 decades of experience in capital equipment projects\, his understanding of the application of Dimensional Analysis as a tool in augmenting human and machine understanding of the physical reality around us has informed and been manifest in various iterations of ‘Organism\, an Engineering Ecosystem’. \n— \nRubinson\, Claude is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Third Wednesdays\, 7-9pm Central Time \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+16699006833\,\,83668672256# US (San Jose) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 646 558 8656 US (New York) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3

SUMMARY:Hack Night!
DESCRIPTION:Hack Night is back! \nJoin us in person at PROS or on Zoom at our usual time (7:00pm Central) for an evening of creative coding. We’ll kick things off with quick introductions and share what we’re hoping to work on—but no worries if you don’t have a project in mind! Let’s be inspired by Lewis Carroll’s “Jabberwocky” and spark (ridiculous/nonsense/brillig) ideas: \n    ‘Twas brillig\, and the slithy toves\n    Did gyre and gimble in the wabe;\n    All mimsy were the borogoves\,\n    And the mome raths outgrabe. \nAfter introductions\, we’ll dive in for ~90 minutes of hacking—whether that means building something new\, breaking something old\, or just experimenting for the fun of it. Pair up if you’d like (we can set up Zoom breakout rooms!)\, or go solo. At 9:00pm\, we’ll regroup to share our successes\, failures\, and successful failures. \nThis isn’t about finishing something or even making measurable progress—it’s about enjoying code and geeking out together. Use whatever language or tools you like—or don’t code at all and just hang out. \nAnd if you’re coming to PROS\, let’s bring some snacks to share! Not required\, but always appreciated. \nBe there or be square! (Do the kids still say that? They should!) 🚀 \n— \nRubinson\, Claude is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Third Wednesdays\, 7-9pm Central Time \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+16699006833\,\,83668672256# US (San Jose) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 646 558 8656 US (New York) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3

SUMMARY:Eric Normand\, "Two and a half more domain modeling lenses"
DESCRIPTION:Abstract: We make better software design decisions when we have more information. Domain modeling proposes that we look to the domain as the primary source of information. To do that\, we need to see our domain from different perspectives\, so I’ve organized my book about domain modeling around lenses. Each lens gives your different information\, and it’s your job to synthesize that into design decisions. I’ve presented seven domain modeling lenses already. In this talk\, I will finish the set and present two more (time and domain) and also add to the runnable specifications lens. \nBio: Eric Normand has been programming functionally since 2001. He teaches\, speaks\, and writes. He consults with companies to help them build better software one function at a time. He lives in Madison\, Wisconsin. You can find his writing and other projects at ericnormand.me. \n\nRubinson\, Claude is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Third Wednesdays\, 7-9pm Central Time \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+16699006833\,\,83668672256# US (San Jose) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 646 558 8656 US (New York) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3

SUMMARY:Richard Feldman\, "The Functional Purity Inference Plan"
DESCRIPTION:Abstract: It’s common for imperative programming languages to announce that they’re adding some new features to support a functional style of programming in that language. The FP experience in those languages is never quite as smooth as it is in functional-first languages\, but it’s still appreciated when that’s the style of code you want to write. \nThe Roc programming language\, which has historically been a purely functional programming language\, is planning to add some new features to support an imperative style of programming. The imperative experience in Roc will never quite be as smooth as it is in imperative-first languages\, but there are some situations when an imperative style genuinely seems like the best fit for the problem at hand. \nSome of the new features are familiar – a `return` statement\, `for` loops\, and opt-in reassignable variables – but the headline feature is “Purity Inference.” With Purity Inference\, functions can be either pure or effectful\, and the type system tracks which is which so you never have to guess. Both styles of function are called the same way\, so there’s no IO/Promise/Future/Task wrapper. But that’s not all…for the full plan\, you’ll have to see the talk! \nBio: Richard is the creator of the Roc functional programming language\, the author of Elm in Action from Manning Publications\, and the instructor for several Frontend Masters workshops: Introduction to Elm\, Advanced Elm\, and Introduction to Rust. He currently works at https://zed.dev on the open-source Zed code editor. \n\nClaude Jager-Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 11 occurrence(s)\nJan 17\, 2024 07:00 PM\nFeb 21\, 2024 07:00 PM\nMar 20\, 2024 07:00 PM\nApr 17\, 2024 07:00 PM\nMay 15\, 2024 07:00 PM\nJun 19\, 2024 07:00 PM\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+12063379723\,\,83668672256# US (Seattle) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 206 337 9723 US (Seattle)\n• +1 213 338 8477 US (Los Angeles)\n• +1 253 215 8782 US (Tacoma)\n• +1 602 753 0140 US (Phoenix)\n• +1 669 219 2599 US (San Jose)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 971 247 1195 US (Portland)\n• +1 470 381 2552 US (Atlanta)\n• +1 646 518 9805 US (New York)\n• +1 646 558 8656 US (New York)\n• +1 651 372 8299 US (Minnesota)\n• +1 786 635 1003 US (Miami)\n• +1 267 831 0333 US (Philadelphia)\n• +1 301 715 8592 US (Washington DC)\n• +1 312 626 6799 US (Chicago)\n• +1 470 250 9358 US (Atlanta) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3 \n— \nJoin by SIP\n• 83668672256@zoomcrc.com \n— \nJoin by H.323\n• 162.255.37.11 (US West)\n• 162.255.36.11 (US East)\n• 115.114.131.7 (India Mumbai)\n• 115.114.115.7 (India Hyderabad)\n• 213.19.144.110 (Amsterdam Netherlands)\n• 213.244.140.110 (Germany)\n• 103.122.166.55 (Australia Sydney)\n• 103.122.167.55 (Australia Melbourne)\n• 149.137.40.110 (Singapore)\n• 64.211.144.160 (Brazil)\n• 149.137.68.253 (Mexico)\n• 69.174.57.160 (Canada Toronto)\n• 65.39.152.160 (Canada Vancouver)\n• 207.226.132.110 (Japan Tokyo)\n• 149.137.24.110 (Japan Osaka) \nMeeting ID: 836 6867 2256\nPasscode: 416074723

SUMMARY:Raúl Chouza\, "Gleam - Introduction to the language and platform"
DESCRIPTION:Abstract: A brief introduction to the Gleam programming language\, we’re going to talk about what makes it “click” as a language but also about the underneath platform/s that make it work. Currently\, Gleam can be compiled to erlang or javascript which we can use to our advantage to put the computation where it makes the most sense \nBio: While at a desk Raúl spends his time getting into rabbit-holes that make him better understand complexity 🌀.  He enjoys the nuances of programming but would like programs to tell you more\, especially when they go wrong. Exploring erlang\, elixir and gleam does fulfill a bit of that ✨.  Otherwise\, loves trying out traditional food; sharing evenings with friends; gaming; has a small family with wife\, baby and cat 🦦. \n\nClaude Jager-Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 11 occurrence(s)\nJan 17\, 2024 07:00 PM\nFeb 21\, 2024 07:00 PM\nMar 20\, 2024 07:00 PM\nApr 17\, 2024 07:00 PM\nMay 15\, 2024 07:00 PM\nJun 19\, 2024 07:00 PM\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+12063379723\,\,83668672256# US (Seattle) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 206 337 9723 US (Seattle)\n• +1 213 338 8477 US (Los Angeles)\n• +1 253 215 8782 US (Tacoma)\n• +1 602 753 0140 US (Phoenix)\n• +1 669 219 2599 US (San Jose)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 971 247 1195 US (Portland)\n• +1 470 381 2552 US (Atlanta)\n• +1 646 518 9805 US (New York)\n• +1 646 558 8656 US (New York)\n• +1 651 372 8299 US (Minnesota)\n• +1 786 635 1003 US (Miami)\n• +1 267 831 0333 US (Philadelphia)\n• +1 301 715 8592 US (Washington DC)\n• +1 312 626 6799 US (Chicago)\n• +1 470 250 9358 US (Atlanta) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3 \n— \nJoin by SIP\n• 83668672256@zoomcrc.com \n— \nJoin by H.323\n• 162.255.37.11 (US West)\n• 162.255.36.11 (US East)\n• 115.114.131.7 (India Mumbai)\n• 115.114.115.7 (India Hyderabad)\n• 213.19.144.110 (Amsterdam Netherlands)\n• 213.244.140.110 (Germany)\n• 103.122.166.55 (Australia Sydney)\n• 103.122.167.55 (Australia Melbourne)\n• 149.137.40.110 (Singapore)\n• 64.211.144.160 (Brazil)\n• 149.137.68.253 (Mexico)\n• 69.174.57.160 (Canada Toronto)\n• 65.39.152.160 (Canada Vancouver)\n• 207.226.132.110 (Japan Tokyo)\n• 149.137.24.110 (Japan Osaka) \nMeeting ID: 836 6867 2256\nPasscode: 416074723

SUMMARY:Hack Night!
DESCRIPTION:Let’s do a hack night!  Online! \nWe’ll gather on Zoom at the usual date and time (Wed\, July 17 @ 7pm central) to say hi and briefly discuss what we’re hoping to work on for the evening.  Don’t worry if you don’t have a specific project in mind\, I’ll also provide a creative prompt or two ahead of time below for inspiration! \nWe’ll spend ~90 minutes hacking away at our projects before returning to the Zoom room at 9:00pm to present our successes\, failures and successful failures!  Maybe people will want to pair up; we can create breakout rooms for you.  There’s no expectation that we’ll finish what we start\, or even make any progress at all!  Let’s just get together to have some fun with code. \nNo need to use a functional programming language; use whatever languages and tools you want.  Heck\, maybe you don’t want to do any coding at all and just want to hang out in the Zoom meeting room to chat.  That’s great too! \n— \nHere are two FP-related prompts to get your creative juices flowing: \n\n“Infinite recursion?”\n“Errors\, like straws\, upon the surface flow;He who would search for pearls must dive below.” (John Dryden\, 1678\, “All for Love”)\n\n— \nRubinson\, Claude is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jul 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 5 occurrence(s)\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+16699006833\,\,83668672256# US (San Jose) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 646 558 8656 US (New York) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3

SUMMARY:3 Short Talks: 2 on F#\, 1 on RC
DESCRIPTION:Note: As of this month\, the in-person component of our meetings will be hosted by PROS at 3200 Kirby Drive\, Suite 600. \nThis month\, we’ll have three short talks: \n\nClaude Jager-Rubinson\, “The Recurse Center”\nThe Recurse Center (RC) hosts programming retreats (“batches”) founded upon the complementary pillars of radical self-direction and community engagement\, guided by three directives: “work at the edge of your abilities\,” “build your volitional muscles\,” and “learn generously.”  Claude will reflect upon his experiences at RC and share what he has been working on during his batch. \nBio: Claude Jager-Rubinson is Associate Professor of Sociology at the University of Houston–Downtown (Houston\, Texas\, USA) where he teaches courses on research methods\, social inequality\, and culture. His research program has three tracts: methodological research on developing formal methods of qualitative research\, focusing on qualitative comparative analysis (QCA); sociological research on the relationship between the global political-economy and aesthetic form; and health services research on the conditions that facilitate/hinder the success of interventions designed to improve patient outcomes.\nJohn Cavnar-Johnson “High performance JSON processing in F#”\nSo\, sometimes I do care about performance. One of those times is when I need to process millions of JSON messages as quickly as possible. Join me for a very quick introduction to writing high performance code in F# using Microsoft’s Utf8JsonReader.\n\nBio: John Cavnar-Johnson is a lead software developer at Crane Worldwide Logistics where he gets to write F# every day. In the last 30 years\, he’s been a corporate developer\, IT sysadmin\, trainer\, software development manager\, IT enterprise architect\, consultant\, and entrepreneur\, but mostly he’s spent his time solving problems and hooking stuff together. In his spare time\, he likes reading\, drinking craft beer\, and playing with his grandkids. \n\n\nChristopher Bremer\, “Active Patterns for Lazy Developers”\nActive Patterns are one of my favorite parts of F# and I’m excited to share all the dumb ways I use them. In short\, an active pattern is a function that allows custom destructuring of an object (i.e. in a switch statement). But they are so much more! They compose! They are algebraic! They can replace gross nested if-else statements and anemic domains models! In this lightning talk\, I will build a toy console app to show off ways that you\, too\, can abuse this language feature.Bio: Chris is the software simulation manager at NOV ReedHycalog in Conroe\, TX\, where he manages a team of engineers and data scientists. His group supports the drill bit design team by providing on demand wellbore simulation and analysis. Prior to working in software\, Chris was a research mathematician studying algebraic geometry and representation theory at University of Chicago and Louisiana State University.\n\n— \nClaude Jager-Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 11 occurrence(s)\nJan 17\, 2024 07:00 PM\nFeb 21\, 2024 07:00 PM\nMar 20\, 2024 07:00 PM\nApr 17\, 2024 07:00 PM\nMay 15\, 2024 07:00 PM\nJun 19\, 2024 07:00 PM\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+12063379723\,\,83668672256# US (Seattle) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 206 337 9723 US (Seattle)\n• +1 213 338 8477 US (Los Angeles)\n• +1 253 215 8782 US (Tacoma)\n• +1 602 753 0140 US (Phoenix)\n• +1 669 219 2599 US (San Jose)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 971 247 1195 US (Portland)\n• +1 470 381 2552 US (Atlanta)\n• +1 646 518 9805 US (New York)\n• +1 646 558 8656 US (New York)\n• +1 651 372 8299 US (Minnesota)\n• +1 786 635 1003 US (Miami)\n• +1 267 831 0333 US (Philadelphia)\n• +1 301 715 8592 US (Washington DC)\n• +1 312 626 6799 US (Chicago)\n• +1 470 250 9358 US (Atlanta) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3 \n— \nJoin by SIP\n• 83668672256@zoomcrc.com \n— \nJoin by H.323\n• 162.255.37.11 (US West)\n• 162.255.36.11 (US East)\n• 115.114.131.7 (India Mumbai)\n• 115.114.115.7 (India Hyderabad)\n• 213.19.144.110 (Amsterdam Netherlands)\n• 213.244.140.110 (Germany)\n• 103.122.166.55 (Australia Sydney)\n• 103.122.167.55 (Australia Melbourne)\n• 149.137.40.110 (Singapore)\n• 64.211.144.160 (Brazil)\n• 149.137.68.253 (Mexico)\n• 69.174.57.160 (Canada Toronto)\n• 65.39.152.160 (Canada Vancouver)\n• 207.226.132.110 (Japan Tokyo)\n• 149.137.24.110 (Japan Osaka) \nMeeting ID: 836 6867 2256\nPasscode: 416074723

SUMMARY:Jeffery Olson\, "System R­—A Practical Lambda Calculus Made for Extensibility in Rust"
DESCRIPTION:Abstract: This will be a presentation on lambda calculi\, their differing varieties and corresponding expressiveness\, and a particular implementation: System R—a lambda calculus\, written in Rust\, built for extensibility and practical use cases. \nMany programming languages (especially in the world of FP) we use today are implemented atop layers of academic theory modeled as lambda calculi. Advances over the last 9+ decades have given us a rich toolset with which to develop sophisticated systems suitable for everyday use. \nWhether it’s Hindley-Milner\, dependent types\, linear types\, or algebraic effects the academic literatures often communicate advances in computer science via a lambda calculus\, often starting from a popularly-known base point\, extended in novel ways appropriate to the domain. \nSystem R is a lambda calculus implementation that enables the creation of more advanced calculi that translate-downward back into System R\, which is intended to operate as a “bottom”-level bytecode. System R is itself a System F dialect (in the sense of TAPL et al). The base Kind & Type system include a rich set of primitive values (robust numerics\, bytes\, etc)\, and the Curry-Howard correspondence tells us it is a suitable bytecode-level substrate for converting to an infinite number of computing backends (wasm\, Rust/C/Fortran/Forth\, AOT\, etc). \nAs mentioned above\, the unifying concept for the above capabilities is that the entire toolchain is built for extensibility. \nYou can learn more at https://github.com/olsonjeffery/system_r \nBio: Jeffery Olson is currently a Staff Engineer at GMV Syncromatics in Houston\, TX.  His path to programming passes through an early enthusiasm for Linux/FOSS software since the late 90s\, a stint in the Army and a tech career starting in Seattle before moving to Houston in 2014. He began contributing to Rust in 2012\, working mostly in the standard library\, contributing initial versions of the network and filesystem APIs. His perspective is shaped by an interest in understanding the needs of\, then solving real problems for\, customers along with a lifelong curiosity for computing technology that has led him all over the map. \n\nClaude Jager-Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 11 occurrence(s)\nJan 17\, 2024 07:00 PM\nFeb 21\, 2024 07:00 PM\nMar 20\, 2024 07:00 PM\nApr 17\, 2024 07:00 PM\nMay 15\, 2024 07:00 PM\nJun 19\, 2024 07:00 PM\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+12063379723\,\,83668672256# US (Seattle) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 206 337 9723 US (Seattle)\n• +1 213 338 8477 US (Los Angeles)\n• +1 253 215 8782 US (Tacoma)\n• +1 602 753 0140 US (Phoenix)\n• +1 669 219 2599 US (San Jose)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 971 247 1195 US (Portland)\n• +1 470 381 2552 US (Atlanta)\n• +1 646 518 9805 US (New York)\n• +1 646 558 8656 US (New York)\n• +1 651 372 8299 US (Minnesota)\n• +1 786 635 1003 US (Miami)\n• +1 267 831 0333 US (Philadelphia)\n• +1 301 715 8592 US (Washington DC)\n• +1 312 626 6799 US (Chicago)\n• +1 470 250 9358 US (Atlanta) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3 \n— \nJoin by SIP\n• 83668672256@zoomcrc.com \n— \nJoin by H.323\n• 162.255.37.11 (US West)\n• 162.255.36.11 (US East)\n• 115.114.131.7 (India Mumbai)\n• 115.114.115.7 (India Hyderabad)\n• 213.19.144.110 (Amsterdam Netherlands)\n• 213.244.140.110 (Germany)\n• 103.122.166.55 (Australia Sydney)\n• 103.122.167.55 (Australia Melbourne)\n• 149.137.40.110 (Singapore)\n• 64.211.144.160 (Brazil)\n• 149.137.68.253 (Mexico)\n• 69.174.57.160 (Canada Toronto)\n• 65.39.152.160 (Canada Vancouver)\n• 207.226.132.110 (Japan Tokyo)\n• 149.137.24.110 (Japan Osaka) \nMeeting ID: 836 6867 2256\nPasscode: 416074723

DESCRIPTION:Abstract: I’d like to talk about a new relational programming language I’ve just started working on\, attempting to combine the pure relationality of miniKanren with better control of search and constraint solving.  In particular\, the language should make it easier to implement efficient program synthesis algorithms.  Following Kowalski’s famous paper\, `Algorithm = Logic + Control`\, the language will separate logical specification from control via a tactics language.  This language is inspired by Dan Friedman’s original vision of miniKanren\, suggestions by Michael Ballantyne to create this type of language\, and conversations with Greg Rosenblatt\, Nada Amin\, Jason Hemann\, Dmitri Boulytchev\, and many others in the miniKanren community. \nBio: Will Byrd is a scientist at the Hugh Kaul Precision Medicine Institute at the University of Alabama at Birmingham.  He is co-author of both editions of ‘The Reasoned Schemer’\, and one of the creators of the miniKanren relational programming language.  Will is also one of the creators of mediKanren\, a system for bio-medical reasoning based on miniKanren\, and funded under the NIH NCATS Biomedical Data Translator Project. \n\nClaude Jager-Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 11 occurrence(s)\nJan 17\, 2024 07:00 PM\nFeb 21\, 2024 07:00 PM\nMar 20\, 2024 07:00 PM\nApr 17\, 2024 07:00 PM\nMay 15\, 2024 07:00 PM\nJun 19\, 2024 07:00 PM\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+12063379723\,\,83668672256# US (Seattle) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 206 337 9723 US (Seattle)\n• +1 213 338 8477 US (Los Angeles)\n• +1 253 215 8782 US (Tacoma)\n• +1 602 753 0140 US (Phoenix)\n• +1 669 219 2599 US (San Jose)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 971 247 1195 US (Portland)\n• +1 470 381 2552 US (Atlanta)\n• +1 646 518 9805 US (New York)\n• +1 646 558 8656 US (New York)\n• +1 651 372 8299 US (Minnesota)\n• +1 786 635 1003 US (Miami)\n• +1 267 831 0333 US (Philadelphia)\n• +1 301 715 8592 US (Washington DC)\n• +1 312 626 6799 US (Chicago)\n• +1 470 250 9358 US (Atlanta) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3 \n— \nJoin by SIP\n• 83668672256@zoomcrc.com \n— \nJoin by H.323\n• 162.255.37.11 (US West)\n• 162.255.36.11 (US East)\n• 115.114.131.7 (India Mumbai)\n• 115.114.115.7 (India Hyderabad)\n• 213.19.144.110 (Amsterdam Netherlands)\n• 213.244.140.110 (Germany)\n• 103.122.166.55 (Australia Sydney)\n• 103.122.167.55 (Australia Melbourne)\n• 149.137.40.110 (Singapore)\n• 64.211.144.160 (Brazil)\n• 149.137.68.253 (Mexico)\n• 69.174.57.160 (Canada Toronto)\n• 65.39.152.160 (Canada Vancouver)\n• 207.226.132.110 (Japan Tokyo)\n• 149.137.24.110 (Japan Osaka) \nMeeting ID: 836 6867 2256\nPasscode: 416074723

SUMMARY:Eric Normand\, "Four Domain Modeling Lenses"
DESCRIPTION:Abstract: Software design is about making decisions within a complex\, multidimensional space. Instead of relying on rules that cannot cope with the complexity of design\, we should focus on seeing our software from various useful perspectives. Each “lens” will help you extract more information about the problem your software is trying to solve. That added information will help will help you make better software design decisions. The four lenses we cover in this talk are composition\, scope\, platform\, and runnable specifications. \nThis talk builds upon material recently presented in https://ericnormand.me/speaking/func-prog-sweden-2023.  While not required\, Eric suggests that it would be beneficial to view this talk beforehand.  HFPUG will therefore host a screening of the talk at Improving starting at 6pm; Eric will then join us at 7pm.  (The 6pm screening probably won’t be streamed via Zoom; Eric’s 7pm talk definitely will be.) \nBio: Eric Normand has been programming functionally since 2001. He aims to help the world make better software one model at a time. He lives with his family in Madison\, Wisconsin. You can find his writing and other projects at ericnormand.me. \n\nClaude Jager-Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 17\, 2024 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 20\, 2024\, 11 occurrence(s)\nJan 17\, 2024 07:00 PM\nFeb 21\, 2024 07:00 PM\nMar 20\, 2024 07:00 PM\nApr 17\, 2024 07:00 PM\nMay 15\, 2024 07:00 PM\nJun 19\, 2024 07:00 PM\nJul 17\, 2024 07:00 PM\nAug 21\, 2024 07:00 PM\nSep 18\, 2024 07:00 PM\nOct 16\, 2024 07:00 PM\nNov 20\, 2024 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZcrceGuqTkoH9Lz2KOcwwZqYRmqgda4Bhi1/ics?icsToken=98tyKuGrqD0iHNOXshyBRpwqBI_oWe7wtnpBgvpxhk3OLCNEdTnnD9BPI7V7EYzy \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/83668672256?pwd=Wld3QXhkczVMaktYYmJQUnp2aG5VZz09 \nMeeting ID: 836 6867 2256\nPasscode: recursion \n— \nOne tap mobile\n+13462487799\,\,83668672256# US (Houston)\n+12063379723\,\,83668672256# US (Seattle) \n— \nDial by your location\n• +1 346 248 7799 US (Houston)\n• +1 206 337 9723 US (Seattle)\n• +1 213 338 8477 US (Los Angeles)\n• +1 253 215 8782 US (Tacoma)\n• +1 602 753 0140 US (Phoenix)\n• +1 669 219 2599 US (San Jose)\n• +1 669 900 6833 US (San Jose)\n• +1 720 928 9299 US (Denver)\n• +1 971 247 1195 US (Portland)\n• +1 470 381 2552 US (Atlanta)\n• +1 646 518 9805 US (New York)\n• +1 646 558 8656 US (New York)\n• +1 651 372 8299 US (Minnesota)\n• +1 786 635 1003 US (Miami)\n• +1 267 831 0333 US (Philadelphia)\n• +1 301 715 8592 US (Washington DC)\n• +1 312 626 6799 US (Chicago)\n• +1 470 250 9358 US (Atlanta) \nMeeting ID: 836 6867 2256 \nFind your local number: https://uhd.zoom.us/u/khzdUKqt3 \n— \nJoin by SIP\n• 83668672256@zoomcrc.com \n— \nJoin by H.323\n• 162.255.37.11 (US West)\n• 162.255.36.11 (US East)\n• 115.114.131.7 (India Mumbai)\n• 115.114.115.7 (India Hyderabad)\n• 213.19.144.110 (Amsterdam Netherlands)\n• 213.244.140.110 (Germany)\n• 103.122.166.55 (Australia Sydney)\n• 103.122.167.55 (Australia Melbourne)\n• 149.137.40.110 (Singapore)\n• 64.211.144.160 (Brazil)\n• 149.137.68.253 (Mexico)\n• 69.174.57.160 (Canada Toronto)\n• 65.39.152.160 (Canada Vancouver)\n• 207.226.132.110 (Japan Tokyo)\n• 149.137.24.110 (Japan Osaka) \nMeeting ID: 836 6867 2256\nPasscode: 416074723 \n

SUMMARY:Christopher Bremer\, "Let's try Bolero\, an F# web framework built on Blazor and Elmish"
DESCRIPTION:When my team decided it was time to migrate one of our web apps away from AngularJS [^1]\, Blazor seemed like a good fit. Javascript isn’t really one of our core competencies\, but we needed a more robust client than\, say\, HTMX. One of the devs suggested we look into Bolero. We prefer F# for our technical applications\, and we were already familiar with some of the design principles espoused by the authors. Four months later\, we are in production and quite pleased with the results!\n\nBolero is a library that brings functional Model-View-Update[^3] to the Blazor ecosystem. In short\, the MVU architecture attempts to decrease the complexity of modern asynchronous web apps. The application state (the “model”) is stored immutably. Updates to the model are queued in a global message buffer\, and all data flows in a single direction.\n\nIn this talk\, I’ll walk through a sample Bolero application[^4]. I’ll cover ways to avoid standard MVU pitfalls and show how to implement some nice UX features (debounce\, polling\, time travel(?!)). I’ll show you how the discipline of MVU combined with the flexibility of F# (and the .NET ecosystem) simplifies UI development for a non front-end dev like me!\n\n[^1]: That’s AngularJS 1.18\, the original[^2]\, not Angular 16.9\n[^2]: yes\, in 2023.\n[^3]: AKA the Elm architecture. There are other MVU architectures (Maui\, SwiftUI\, Redux) that take slightly different approaches.\n[^4]: clbrem/bolero-agents\n\nBiography: Chris is the software simulation manager at NOV ReedHycalog in Conroe\, TX\, where he manages a team of engineers and data scientists. His group supports the drill bit design team by providing on demand wellbore simulation and analysis. Prior to working in software\, Chris was a research mathematician studying algebraic geometry and representation theory at University of Chicago and Louisiana State University.\n\nThis is a hybrid meeting.

SUMMARY:Richard Feldman\, "Incrementally Adopting Roc at Vendr"
DESCRIPTION:Abstract: Introducing a new programming language to an existing stack always comes with challenges. In this talk\, Richard discusses the incremental adoption strategy he’s been using at Vendr to introduce Roc to the company’s existing backend. \nThis has involved two different approaches\, each with their own pros and cons: one\, building a separate standalone Roc service\, and two\, creating the ability for the existing Node.js TypeScript backend to import and call Roc functions directly inline. The “direct import” approach is usually found in compile-to-X languages like Clojure and Elm\, but in Roc’s case\, this can be done using either WebAssembly or Native Node Addons. (We tried both approaches in production\, and the talk will discuss the pros and cons of each.) \nBio: \nRichard is the creator of the Roc functional programming language\, the author of “Elm in Action” from Manning Publications\, and the instructor for several Frontend Masters workshops: Introduction to Elm\, Advanced Elm\, and Introduction to Rust. He is currently a Principal Engineer at Vendr\, where he’s working on introducing Roc to the company’s backend to complement its longstanding Elm frontend. \n\nThis is a hybrid meeting.

SUMMARY:Ahmed Hammad\, "Property-based Testing in F#"
DESCRIPTION:Abstract: This talk discusses the benefits of Property Based Testing (PBT)\, an overlooked testing methodology. It introduces PBT in F# using FsCheck\, emphasizing the importance of invariants in constructing effective tests. While FsCheck is the specific platform used\, the concepts and principles presented are broadly applicable to any Property Based Testing system. \nBio: Ahmed Hammad is a Senior Full Stack Developer at Improving. He’s been developing software for more years than he’d care to remember. The closest he came to making a living from Functional Programming was finding a way to use eLisp at a role straight out of college\, but his bread and butter is C# and JavaScript (React/Redux). His hobbies include: \n\nReading non-fiction (mostly Math\, Philosophy & Computer Science)\nWriting\nHanging out with friends\nTrying out new programming languages and tools (e.g.: Racket (Scheme)\, Factor)\nWatching Bad Movies\nExploring the Intersection of Math & Programming\n\nHe lives alone with his cat Dru. \n\nThis is a hybrid meeting.

SUMMARY:Jade Allen\, "Erlang Timer Wheels"
DESCRIPTION:Abstract: How can you accurately and easily scale events to trigger at a given time in a distributed system. This is a critical task for many asynchronous systems – Kafka for example has a timer system which helps it decide when it ought to next check its queues for new input. But there are other excellent examples of highly scalable and accurating timing systems such as the one implemented in the Erlang run time system. Erlang uses “timer wheels” which are inspired by a classic systems paper from 1987 – we are going to talk about the paper and how its implementation in Erlang enables massively concurrent and accurate timing for events. \n\nhttp://www.cs.columbia.edu/~nahum/w6998/papers/sosp87-timing-wheels.pdf\nhttps://blog.acolyer.org/2015/11/23/hashed-and-hierarchical-timing-wheels/\n\nBiography: Jade Allen has been a software developer for over 20 years. She currently works at Helium Inc where she helps maintain a large (Byzantine fault tolerant) distributed system that relays sensor data from IoT devices to the Internet. She has worked on a variety of software projects over her career from databases to storage services to systems automation tools. Her avocational interests involve spin class\, cooking\, and cheesy pop culture references. \n\nThis is a hybrid meeting.

I’m a web developer at MasterWord Services where we use Haskell to build an ERP system. I’ve been using Haskell for 4 years and I’m a big fan of the functional programing paradigm. Feel free to send me an email if you want to learn more about how Haskell is used in web development. \n\nThis is a hybrid meeting. Please join us in person at Improving or online via Zoom. \nClaude Rubinson is inviting you to a scheduled Zoom meeting. \nTopic: Houston Functional Programmers\nTime: Jan 18\, 2023 07:00 PM Central Time (US and Canada)\nEvery month on the Third Wed\, until Nov 15\, 2023\, 11 occurrence(s)\nJan 18\, 2023 07:00 PM\nFeb 15\, 2023 07:00 PM\nMar 15\, 2023 07:00 PM\nApr 19\, 2023 07:00 PM\nMay 17\, 2023 07:00 PM\nJun 21\, 2023 07:00 PM\nJul 19\, 2023 07:00 PM\nAug 16\, 2023 07:00 PM\nSep 20\, 2023 07:00 PM\nOct 18\, 2023 07:00 PM\nNov 15\, 2023 07:00 PM\nPlease download and import the following iCalendar (.ics) files to your calendar system.\nMonthly: https://uhd.zoom.us/meeting/tZIkdOiqqzMiE9KjGZH4RidY2HUNNsiytrGX/ics?icsToken=98tyKuGupzgrGNGduBCBRpwAHYjCd-rwmFxHj_p2ljjfK3RhawfPZMp3HJxsGcHE \nJoin Zoom Meeting\nhttps://uhd.zoom.us/j/86931258896?pwd=cjlCL1dDT0d0VE5hUmVrdnhPQVZIZz09 \nMeeting ID: 869 3125 8896\nPasscode: recursion\nOne tap mobile\n+13462487799\,\,86931258896# US (Houston)\n+12063379723\,\,86931258896# US (Seattle) \nDial by your location\n+1 346 248 7799 US (Houston)\n+1 206 337 9723 US (Seattle)\n+1 213 338 8477 US (Los Angeles)\n+1 253 215 8782 US (Tacoma)\n+1 602 753 0140 US (Phoenix)\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 720 928 9299 US (Denver)\n+1 971 247 1195 US (Portland)\n+1 651 372 8299 US (Minnesota)\n+1 786 635 1003 US (Miami)\n+1 267 831 0333 US (Philadelphia)\n+1 301 715 8592 US (Washington DC)\n+1 312 626 6799 US (Chicago)\n+1 470 250 9358 US (Atlanta)\n+1 470 381 2552 US (Atlanta)\n+1 646 518 9805 US (New York)\n+1 646 558 8656 US (New York)\nMeeting ID: 869 3125 8896\nFind your local number: https://uhd.zoom.us/u/kiTOghtR9 \nJoin by SIP\n86931258896@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia Sydney)\n103.122.167.55 (Australia Melbourne)\n149.137.40.110 (Singapore)\n64.211.144.160 (Brazil)\n149.137.68.253 (Mexico)\n69.174.57.160 (Canada Toronto)\n65.39.152.160 (Canada Vancouver)\n207.226.132.110 (Japan Tokyo)\n149.137.24.110 (Japan Osaka)\nMeeting ID: 869 3125 8896\nPasscode: 038441558
