📢 The full agenda for WarsawJS Meetup #116 is now available! 📢 We are delighted to introduce the speakers and topics that will be discussed at our upcoming meeting on July 10th at the Paramount office. We have prepared exceptional presentations that you definitely don't want to miss! 👨🏫 Michał Michalczuk — TypeScript Template Literal Types - Who Needs It Anyway? 👨🏫 A long, long time ago, TypeScript 4.1 brought a major change by introducing Template Literal Types. Following this release, examples like type-based parsers or type-based SQL engines spawned like crazy. In subsequent releases, we got even more Template Literal Types features! Cool. But it doesn’t answer our question: “Who needs it anyway?” I’ll talk about Template Literal Types and we’ll explore more real-life use cases for them beyond the mentioned type-based SQL engine :) 👨🏫 Andrii Romasiun — Writing Secure JavaScript 👨🏫 In my speech, I want to talk about web security and how to write secure JavaScript. I will discuss how small bugs have opened huge vulnerabilities even in big companies like Google and Cloudflare. What are the common and uncommon vulnerabilities in JS full-stack applications (XSS, header poisoning, SQLi, clickjacking, directory traversal, RCE, open redirects, and more), with real-life examples, and how to detect, prevent, and mitigate such vulnerabilities. At the end, I'll give a short talk about how to set up a secure coding environment and why it's important (static code analysis, environment configuration, dependency management). 👨🏫 Przemysław Konefał — Simplicity in the Spectrum: Identifying and Overcoming Overengineering 👨🏫 One of the main pillars of maturing as a developer is mastering the skill of striking the right balance between underengineering and overengineering. This session aims to equip developers with a systematic approach to dealing with the latter. We'll explore the common reasons that drive developers to overshoot their solutions, particularly in the realm of frontend development. Then, we'll discuss the signs and in-code symptoms of unnecessary complexity. In the end, we'll dive into useful heuristics, mental models, and thought filters to refine our approach to project complexity, to find that sweet spot more consistently. Don't miss the opportunity to gain new knowledge and exchange experiences with other developers! Tickets are now available: https://lnkd.in/d3wy-w2z See you on July 10th! 🎉 #WarsawJS #Meetup #TechTalks #CodingCommunity

WarsawJS Meetup #116 without interesting lightning talks? That can't be! So let's introduce the first one 🎊 The first lightning talk will be given by Iga Trydulska — fashion journalist, researcher at K MAG. Iga is a journalist and researcher working at the intersection of fashion and technology. Since 2022, she has held the position of Fashion Editor-at-Large at K MAG Magazine. Her research areas include ethical AI development, creative coding, and gender studies. She is an alumna of London College of Fashion and the Creative Computing Institute (UAL). What will she be presenting for us? ⚡️ How LLMs influence the gender bias portrayed in the media? ⚡️ AI development is unlikely to stop in the near future; however, even at this stage, many instances of sexism can be seen in the products created by generative AI models. The talk will explore how potentially discriminating data is present both in the input and the output of neural networks: from databases to the structure of the layers themselves (for example - working on datasets which are formed by scraping data off websites such as Reddit or Wikipedia, which have a predominately male demographic). Key terms will be defined, and AI developments will be placed in a wider context, which also includes new retouching techniques. Finally, possible answers to this problem will be offered, keeping in mind that many solutions - such as increasing computational power or the dataset size - result in the apophenia phenomenon; increasing societal visual literacy will be presented as a possible way forward. (This is a run-through; I can write a more engaging description for a website, this is for you to check if it is interesting) Social media 🖱 ➛ https://lnkd.in/dzvYmcwX ➛ https://lnkd.in/du8EDv2p ➛ https://lnkd.in/du8EDv2p ➛ https://lnkd.in/dbQqaQAU 🔖 Reservation — https://lnkd.in/d3wy-w2z 👉 Livestream — https://warsawjs.com/live Iga Trydulska will be speaking on Wednesday, 10.07 at 18:30 🕡 at our Meetup.

Droga społeczności WarsawJS, Nasza koleżanka Lena potrzebuje teraz naszej pomocy bardziej niż kiedykolwiek. Organizuje zbiórkę na jej leczenie i każda wpłata przybliża nas do celu. Wierzymy, że razem możemy zrobić różnicę i wspierać Lenę w tej trudnej walce. Zachęcamy Was do dołączenia do zbiórki i podzielenia się informacją z innymi. Wasze wsparcie jest nieocenione. Razem możemy osiągnąć cel jak najszybciej! Dziękujemy za Waszą pomoc i solidarność. WarsawJS
Web Developer (Vue, React, JavaScript, WordPress) | Speaker | Psychologist empowering women and neuro-divergent people
Szybkie pytanie: polecicie dalej moją zbiórkę na leczenie po leczeniu onkologicznym? A teraz długa opowieść. Ostatnio LinkedIn żyje "Polecajka Gate". Kto widział - ten wie, kto nie widział - niech nie nadrabia, nie ma czego. Ot, jest różnica zdań, niektórzy przepraszają, niektórzy żartują. Dzień jak co dzień, tylko zasięgi większe... Czemu "bagatelizuję" tę, jak się okazało, dość nośną sprawę w sieci? Po prostu mam na głowie inne rzeczy. Jak wiecie, od ponad roku szukam zdalnej pracy na etat z elastycznymi godzinami pracy. Freelancing jest dla mnie zbyt nieprzewidywalny - raz jest praca, raz jej nie ma. A ja po prostu nie mam już siły ciągnąć JDG, szukania pracy, ogarniania zleceń które wpadają (jak wpadają) i nauki (jak nie wpadają). Może bym i miała siłę, gdyby nie to, że jest jeszcze jeden wróg, o którym wie część z Was - nowotwór. Sytuacja jest "opanowana", tzn. byłam operowana prawie 3 lata temu i 2 lata brałam hormony jako leczenie uzupełniające. Jednak w trakcie leczenia pracodawca (podkreślam: miał w świetle prawa takie możliwości, nie byłam na L4) zlikwidował m.in. moje stanowisko pracy. Efekt? W momencie gdy czułam się coraz gorzej na hormonoterapii, coraz trudniej mi było wychodzić z domu, i jeszcze kilka dni wcześniej zmarła moja Babcia dostałam metaforycznie z liścia w twarz - czyli wypowiedzenie. Przeszłam na JDG, jakoś zaczęłam działać, ale przy dociążonym leczeniem organizmie było ciężko. Fun fact - zaczęłam jeździć na konferencje, bo poza tym, że uwielbiam dzielić się wiedzą, to... wielu organizatorów konferencji płaci za nocleg. W sytuacji gdzie nie było mnie stać na urlop to naprawdę stała się fajna alternatywa. Tak, jestem wojowniczką, ale to też ma swoje granice... właśnie do nich dotarłam. Kilka miesięcy temu zakończyłam leczenie. Przeszłam uciążliwy "detoks", bo odstawienie hormonów i antydepresantów było dość hardcorowe. Teraz zaczęłam biegać po lekarzach i poza tym, że w wyniku leczenia mam otyłość I stopnia, podejrzenie insulinooporności (no 💩 Sherlock), ból stawów i obrzęki czy menopauzę to jeszcze pojawia się podejrzenie, że przynajmniej kilka innych rzeczy się zepsuło. O PTSD nie wspomnę, bo trudno nie mieć PTSD jak np. jakiś lekarz, wybaczcie określenie, op*rdala pacjenta na korytarzu ujawniając szczegóły leczenia. Podobnych sytuacji miałam na pęczki. Ale cóż, najważniejsze że lekarz sobie ulżył. Tylko, że po iluś latach takiego traktowania + ogólnie traumy ciężko jest nie dorobić się stresu pourazowego. Dobra wiadomość: sporo zmian jest odwracalnych. Zła wiadomość: na odwrócenie tych zmian potrzeba, poza moim zaangażowaniem, pieniędzy. Dobra wiadomość: można mi pomóc, o tu: https://lnkd.in/dfKHmc9j (na leczenie - najważniejsze) Albo tu: https://lnkd.in/dFVk4FgC (na włóczkę, ziemię do kwiatów i kupowanie ebooków, żeby móc żyć czymś innym niż leczenie). To co, udostępnicie taką "polecajkę"? 🤔 #onkosurvivor
