Hello, Jakarta Writer! **Are you a member of [Jakarta Friends](https://www.meetup.com/jakarta-friends/) yet?** Want to see **pictures** of past events? **[Take a look here!](https://www.meetup.com/jakarta-creatives/photos/)** And feel free to upload a few pictures you will take at the event 😊 JakWri and JakFri is **the** biggest, first, most active, and most inclusive MeetUp community in Jakarta… and we invite you to join us for this **WRITERS' CLUB: Give and receive FEEDBACK** **on your writing! 📖✍️🤓** Everyone is always welcome to join our events. Our community is all about creating authentic in-person connections in this urban jungle. Come as you are... it’s the best version of yourself. **ABOUT THE EVENT** What's one of the most difficult part in writing? Getting high-quality feedback! This event addresses exactly this! Plus, writers will have the chance to be part of a friendly community and a support system for fellow creatives. **We want to help and elevate each other!** This is what we will do: We will meet at the indicated time (please don't be late) and everyone who wishes to can drop their name on a box for a lucky draw. One person is selected by chance and will need to have a text **of any kind** (poetry/fiction/non-fiction/essay/article/script/blog/music lyrics/whatever!) ready to share with everyone on a Google drive folder. Then everyone will take their time and read the piece(s) on their own. We allocate **about 90 minutes quiet reading time**. Readers will take notes on what they wish to give feedback to. The author is also welcome to brief readers on what they should pay attention to or give feedback on. People who wishes to be there as readers only (that is, without putting their name in the lucky draw box), are most welcome to! The crucial part is that everyone needs to be respectful of each other's craft and give **polite, constructive feedback**! After reading time, there is the feedback time! **For about 90 minutes, we will discuss what we have read, and give feedback to the author.** Sounds easy, fun, and productive? It is. Everyone will have the chance to learn something new! This event doesn't require any preparation! We will read and give feedback on the spot. It's important that everyone is **on time** and **ready to share their text on Google Drive** for everyone to read, so that we can start without delays! This will be a unique occasion to receive a feedback on your writings (of any kind) and to practice your ability to give and receive feedbacks on texts! Just be ready to share (not mandatory) **a piece of your writing of about 2,000 words** (1,000 to 10,000 words is OK, too, but be aware that a shorter piece is more likely to receive plenty of feedback) as a Google Drive link and grant people access to read. **We have done this event many times before!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *July Meeting - Lightning Talks!* Lightning talks are very short presentations on a topic of your choice (must be related to .NET). Talks should be 15-20 minutes in length and include minimal slides and quick demo (no live coding please). There will be 6 slots available! First come, first serve! **YouTube Link** TBD

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
