Passionate People Meetup - React vs Vue with a deepdive into ProxiesHarijs Deksnis
This document compares React and Vue, discusses their pros and cons, and explores reactivity and the use of proxies in Vue. It finds that Vue has an easier learning curve and smaller size than React, but React has a larger ecosystem. Proxies, introduced in ES2015, allow intercepting and customizing default behavior of operations on objects. Vue 3 uses proxies for reactivity which provides better performance than Vue 2. Proxies are also used for change detection in some React libraries, though come with performance caveats.

The document outlines four pains experienced by developers when using traditional .NET development approaches: 1) Reliance on "magic" frameworks that can cause unexpected errors, 2) Builds that fail due to unpredictable dependencies, 3) Long edit-compile-test cycles, and 4) Rapid obsolescence of skills as technologies change. It proposes four guiding principles to address these pains: 1) Using direct queries over ORM "magic", 2) Ensuring predictable, reproducible builds and environments, 3) Shortening feedback loops through techniques like hot reloading, and 4) Focusing on reusable skills rather than specific technologies. The overall message is that prioritizing business needs over technical wizardry and automation can help developers work more efficiently

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications
