P2 and P3 bugs die in the backlog — the UX nits, the copy, the small fixes.\u003c/p\u003e\n\u003cp\u003eAn AI-native QA team files the bug and immediately points an agent at it. The agent takes a first pass, finds a root cause, proposes a fix, and opens a PR — then sends a test build right back to QA to verify. Along the way the bug is updated in detail, so if it needs escalation to the engineer who built it, all the context is right there. A more advanced team has a \u003ca href=\"/blog/responsible-loop-engineering\"\u003eloop\u003c/a\u003e wired to trigger the minute a bug is filed.\u003c/p\u003e\n\u003ch2 id=\"product-managers\"\u003e\n Product managers\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#product-managers\" aria-label=\"Link to Product managers\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eA PM understands the business and goals well. They write a thoughtful PRD — but it\u0026rsquo;s often 70% done. How are they to keep the full codebase and every edge case in their head? The engineer starts building, hits those edge cases mid-feature, and bounces it back to the PM who has better intuition. Tweak the PRD, back to the engineer. This can happen for every slice of that remaining 30%, and it\u0026rsquo;s frustrating for everyone.\u003c/p\u003e\n\u003cp\u003eAn AI-native PM sends an agent to walk the real code, surface those forks up front, and spin up throwaway prototypes to explore each one. They keep a knowledge base of past decision briefs so the team doesn\u0026rsquo;t rebuild what was already ruled out. With that in hand, they produce a fully specced PRD — and maybe pushing further, include end-to-end tests defining what done looks like.\u003c/p\u003e\n\u003ch2 id=\"designers\"\u003e\n Designers\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#designers\" aria-label=\"Link to Designers\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eDesigners mock up screens in Figma and ship them over, hoping what shows up in production matches their pixel-perfect specs.

They get to play with throwaway builds of the actual codebase and can design towards a stronger, more realistic spec — with real constraints, like how that animation actually runs on an Android 12 device. Polish-related work doesn\u0026rsquo;t die in ticket wasteland anymore. It runs through the same loop QA uses: the agent makes the change and preflights a build for the designer to check by eye. They have the taste, and now the agency to ship it on the spot.\u003c/p\u003e\n\u003ch2 id=\"data-scientists\"\u003e\n Data scientists\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#data-scientists\" aria-label=\"Link to Data scientists\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eData scientists live downstream, so they feel every change last. They\u0026rsquo;re often looped in at the end, when the feature is mostly built and engineers need to tack on the instrumentation. Or worse, they discover engineering renamed an event in a refactor and mission-critical dashboards quietly broke in production — caught days later, when the build is already out.\u003c/p\u003e\n\u003cp\u003eThe old move: file a ticket and wait for engineering\u0026rsquo;s queue. An AI-native data scientist reaches for an agent instead — tracing a break to a renamed event and sending the fix as a PR, or instrumenting a metric they couldn\u0026rsquo;t measure yet without waiting on anyone.\u003c/p\u003e\n\u003cp\u003ePushing further, the old way to test a hypothesis was to ship, wait for real data to accumulate, then lean on engineering and product to make changes. An AI-native data scientist runs the test before anything ships — generating synthetic data and simulating scenarios with agents to show the PM which option wins, then putting up the winning approach as a PR for engineering to review, tweak, and ship.\u003c/p\u003e\n\u003ch1 id=\"so-what-does-the-engineers-role-look-like\"\u003e\n So what does the engineer\u0026rsquo;s role look like?\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#so-what-does-the-engineers-role-look-like\" aria-label=\"Link to So what does the engineer’s role look like?\"\u003e#\u003c/a\u003e\n\u003c/h1\u003e\n\u003cp\u003eIf you noticed a trend above, we\u0026rsquo;re distributing a lot of what engineering typically does to other roles.

I\u0026rsquo;m not saying engineers become PMs or PMs become engineers. I think both are heading toward a \u0026ldquo;product specialist\u0026rdquo; role: highly opinionated people who understand the product so well that they can take an idea to a live feature in days.\u003c/p\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSystem engineers\u003c/strong\u003e: The platform watchers.

These are the people who build and maintain the loops for every other role: the inboxes, the triggers, the verification gates, the escalation paths. QA, PMs, designers, and data scientists shouldn\u0026rsquo;t be wiring those connectors — they should be doing the work described above.

Over the 2023 Xmas holidays, I was watching \u003ca href=\"https://en.wikipedia.org/wiki/The_West_Wing\"\u003eThe West Wing\u003c/a\u003e since it\u0026rsquo;s one of those shows that\u0026rsquo;s recommended highly.

Self care is about making sure you\u0026rsquo;re spending time to do things that inspire and invigorate you. Self care can be fitness, it can be watching that TV show that only you seem to like in your family, it can be eating healthier, it can be taking the time to talk to a therapist or a friend more equipped to listen.

Could this still work? Can this eager hungry new CEO walk the talk, with said bold decisions. The part that might not be immediately obvious here is that in this test, Steve too is opening up the kimono about the video iPods here.\u003c/p\u003e\n\n\n\n\n\n \u003cblockquote\u003e\n \u003cp\u003eThe ease and the speed with which we got the deal done, combined with the fact that it showed an admiration for Apple and its products, blew Steve’s mind. He told me he’d never met anyone in the entertainment business who was willing to try something that might disrupt his own company’s business model.\nSteve responded to boldness. Among his many frustrations was a feeling that it was often too difficult to get anything done with Disney. Every agreement needed to be vetted and analyzed to within an inch of its life, and that’s not how he worked. I wanted him to understand that I didn’t work that way, either, that I was empowered to make a call, and that I was eager to figure out this future together, and to do so quickly.\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\u003cp\u003eA lesson to always remember for any successfull company. The irony here is that Steve functioned this way. A company the size of Apple (i presume) can\u0026rsquo;t. Yet Steve pulled it off with Apple.

His experience with Disney so far hadn’t provided any evidence to the contrary. He went on, writing his cons in full sentences across the board. “Fixing Disney Animation will take too long and will burn John and Ed out in the process.” “There’s too much ill will and the healing will take years.” “Wall Street will hate it.” “Your board will never let you do it.” There were many more, but one in all cap letters, “DISTRACTION WILL KILL PIXAR’S CREATIVITY.”\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\u003cp\u003eCulture, individual contributor burnout, killing Creativity. I love how these were so important to Steve, more so than any other factor. Most companies like to \u003cem\u003etalk\u003c/em\u003e about these things and mostly cause it worked for Apple. But such massive positive change can be brought about in a company when leaders a) understand these qualities and b) hold them up high.\u003c/p\u003e\n\n\n\n\n\n \u003cblockquote\u003e\n \u003cp\u003eSeveral members of the board were still opposed, but the moment the Pixar team started talking, everyone in the room was transfixed. They had no notes, no decks, no visual aids. They just talked\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\u003cp\u003eI\u0026rsquo;ve been interested in public speaking for quite sometime, and I\u0026rsquo;ve always believed this to be a mark of a truly engaging speaker.

I\u0026rsquo;ve got some experience in the Android development side now and can hold my own. But it\u0026rsquo;s just so refreshing to go into something that you know very little but can learn.

If you want a more detailed (and accurate) description of the details, head on over to \u003ca href=\"http://akarnokd.blogspot.com/2016/03/operator-fusion-part-1.html\"\u003eDavid\u0026rsquo;s blog\u003c/a\u003e for some of those details.\u003c/p\u003e\n\u003cp\u003eSo if you don\u0026rsquo;t need some of these additional optimizations, use the \u003ca href=\"http://reactivex.io/RxJava/javadoc/io/reactivex/Observable.html#hide--\"\u003e\u003ccode\u003e.hide()\u003c/code\u003e\u003c/a\u003e operator.\u003c/p\u003e\n\u003cp\u003eI also love looking at the \u003ca href=\"https://github.com/ReactiveX/RxJava/blob/2.x/src/main/java/io/reactivex/Observable.java#L9459\"\u003esource code\u003c/a\u003e, so i did just that for \u003ccode\u003e.hide\u003c/code\u003e and noticed it simply wraps and sends the observable with \u003ca href=\"https://github.com/ReactiveX/RxJava/blob/579e90dc21937b900877a8baf3918cdca22d3a91/src/main/java/io/reactivex/internal/operators/observable/ObservableHide.java\"\u003e\u003ccode\u003eObservableHide\u003c/code\u003e\u003c/a\u003e.

A key difference is you can create and associate Disposable resources with it and dispose them together from within the onError() and onComplete() methods you implement.

Disney, Pixar’s distribution partner, knew that it took 3-4 years to make an animated film. They argued that it was too late to start over and that Pixar should release the film as is. But Pixar refused, deciding instead to tear up the story and re-write it from scratch. The studio pushed itself to the brink of collapse to complete the new version of Toy Story 2 on time, and the film was a huge commercial and critical success.

The race condition occurs because there are two subscribers here (debounce and buffer) and they may come and go at different points. Remember that the RxBus is backed by a hot/live Subject which is constantly emitting items. By using the \u003ccode\u003eshare\u003c/code\u003e operator we guarantee a reference to the same source, but NOT that they\u0026rsquo;ll receive the exact same items if the subscribers enter at different points of time. Ben explains this well:\u003c/p\u003e\n\n\n\n\n\n \u003cblockquote\u003e\n \u003cp\u003eThe race condition is when the two consumers subscribe. Often on a hot stream it doesn\u0026rsquo;t matter when subscribers come and go, and refCount is perfect for that. The race condition refCount protects against is having only 1 active subscription upstream. However, if 2 Subscribers subscribe to a refcounted stream that emits 1, 2, 3, 4, 5, the first may get 1, 2, 3, 4, 5 and the second may get 2, 3, 4, 5.\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\n\n\n\n\n \u003cblockquote\u003e\n \u003cp\u003eTo ensure all subscribers start at exactly the same time and get the exact same values, refCount can not be used. Either ConnectableObservable with a manual, imperative invocation of connect needs to be done, or the variant of publish(function) which connects everything within the function before connecting the upstream.\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\u003cp\u003eIn our usage it\u0026rsquo;s almost immediate so it probably wouldn\u0026rsquo;t matter a whole lot but considering the use case, it\u0026rsquo;s ideal to have the exact same events emitted for the debouncedBuffer usecase. \u003ca href=\"https://github.com/kaushikgopal/Android-RxJava/blob/master/app/src/main/java/com/morihacky/android/rxjava/rxbus/RxBusDemo_Bottom3Fragment.java\"\u003eI added a third improved implementation to handle this race condition\u003c/a\u003e:\u003c/p\u003e\n\u003cdiv class=\"highlight\"\u003e\u003cpre tabindex=\"0\" style=\"color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;\"\u003e\u003ccode class=\"language-java\" data-lang=\"java\"\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\u003cspan style=\"color:#75715e\"\u003e// don\u0026#39;t start emitting items just yet by turning the observable to a connected one\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003eConnectableObservable\u003cspan style=\"color:#f92672\"\u003e\u0026lt;\u003c/span\u003eObject\u003cspan style=\"color:#f92672\"\u003e\u0026gt;\u003c/span\u003e tapEventEmitter \u003cspan style=\"color:#f92672\"\u003e=\u003c/span\u003e _rxBus.\u003cspan style=\"color:#a6e22e\"\u003etoObserverable\u003c/span\u003e().\u003cspan style=\"color:#a6e22e\"\u003epublish\u003c/span\u003e();\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003etapEventEmitter.\u003cspan style=\"color:#a6e22e\"\u003epublish\u003c/span\u003e((Func1) (stream) \u003cspan style=\"color:#f92672\"\u003e-\u0026gt;\u003c/span\u003e {\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e \u003cspan style=\"color:#75715e\"\u003e// inside `publish`, \u0026#34;stream\u0026#34;

In my head I thought I could simply use the \u003ccode\u003edebounce\u003c/code\u003e operator (like the \u003ca href=\"https://github.com/kaushikgopal/RxJava-Android-Samples/blob/master/app/src/main/java/com/morihacky/android/rxjava/fragments/DebounceSearchEmitterFragment.java\"\u003edebounce search example\u003c/a\u003e) and be on my jolly way, but this was not to be\u0026hellip; From the always helpful \u003ca href=\"https://github.com/ReactiveX/RxJava/wiki/Alphabetical-List-of-Observable-Operators\"\u003eRxJava wiki\u003c/a\u003e:\u003c/p\u003e\n\n\n\n\n\n \u003cblockquote\u003e\n \u003cp\u003e\u003ccode\u003edebounce\u003c/code\u003e - only emit an item from the source Observable after a particular timespan has passed without the Observable emitting any other items\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\u003cp\u003eI wanted the \u0026ldquo;\u003cem\u003eafter a particular timespan has passed without the Observable emitting any other items\u003c/em\u003e\u0026rdquo; part of debounce, but I needed the whole \u003cem\u003elist of emitted items\u003c/em\u003e (not just a single item). The\u003ccode\u003ebuffer\u003c/code\u003eoperator also seemed promising:\u003c/p\u003e\n\n\n\n\n\n \u003cblockquote\u003e\n \u003cp\u003e\u003ccode\u003ebuffer\u003c/code\u003e - periodically gather items from an Observable into bundles and emit these bundles rather than emitting the items one at a time\u003c/p\u003e\n\n \u003c/blockquote\u003e\n\u003cp\u003e\u0026ldquo;emit as bundles\u0026rdquo;, perfect! uh\u0026hellip; not exactly, it says \u0026ldquo;periodically\u0026rdquo; and that literally means periodically. So EVERY X seconds/minutes it will emit a list of objects regardless of whether there were any taps/events. This would mean a bunch of empty lists would periodically be emitted when no taps were registered. I could get the example working if I tweaked the time component for \u003ccode\u003ebuffer\u003c/code\u003e just enough and \u003ccode\u003efilter\u003c/code\u003e out the empty results, but it was a hack and not the way of the Rx.\u003c/p\u003e\n\u003cp\u003eWhat I really needed was a selective combination of debounce and buffer - a \u0026ldquo;debouncedBuffer\u0026rdquo; operator. Such an operator doesn\u0026rsquo;t exist but you could achieve something similar by calling \u003ccode\u003e.buffer()\u003c/code\u003e with a special \u0026ldquo;boundry observable\u0026rdquo; parameter, as Jedi master Ben Christensen points out in this \u003ca href=\"http://stackoverflow.com/questions/24828897/how-to-group-events-by-idle-periods-using-reactive-extensions\"\u003eStack Overflow post\u003c/a\u003e (the Rx is strong with this one).\u003c/p\u003e\n\u003cp\u003eEssentially, if you pass an observable as a parameter to \u003ccode\u003ebuffer\u003c/code\u003e, every time this observable emits an item, \u003ccode\u003ebuffer\u003c/code\u003e will take the source observable and emit a \u003cem\u003elist\u003c/em\u003e of items from the \u003cem\u003esource\u003c/em\u003e observable (instead of the items emitted by the boundary observable).\u003c/p\u003e\n\u003cdiv class=\"highlight\"\u003e\u003cpre tabindex=\"0\" style=\"color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;\"\u003e\u003ccode class=\"language-java\" data-lang=\"java\"\u003e\u003cspan style=\"display:flex;\"\u003e\u003cspan\u003e\u003cspan style=\"color:#f92672\"\u003e\u0026lt;\u003c/span\u003eSource Observable For Actual Events\u003cspan style=\"color:#f92672\"\u003e\u0026gt;\u003c/span\u003e.\u003cspan style=\"color:#a6e22e\"\u003ebuffer\u003c/span\u003e(\u003cspan style=\"color:#f92672\"\u003e\u0026lt;\u003c/span\u003eBoundary Observable that only tells \u003cspan style=\"color:#e6db74\"\u003e\u0026#34;when\u0026#34;\u003c/span\u003e \u003cspan style=\"color:#66d9ef\"\u003eto\u003c/span\u003e take items from the Source\u003cspan style=\"color:#f92672\"\u003e\u0026gt;\u003c/span\u003e)\n\u003c/span\u003e\u003c/span\u003e\u003c/code\u003e\u003c/pre\u003e\u003c/div\u003e\u003cp\u003eSo what we\u0026rsquo;re going to do is use a \u0026ldquo;debouncedEventEmitter\u0026rdquo; as our boundary observable.

The Observable here doesn\u0026rsquo;t want to know who the events are going out to, just that they\u0026rsquo;ve gone out. In other words the Observable (a.k.a Publisher) doesn\u0026rsquo;t want to know who the Observers (a.k.a Subscribers) are.\u003c/p\u003e\n\u003ch2 id=\"why-the-anonymity\"\u003e\n Why the anonymity?\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#why-the-anonymity\" aria-label=\"Link to Why the anonymity?\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eIt allows for this thing called \u0026ldquo;decoupling\u0026rdquo;, which is a good word in computer programming. You want to keep coupling as low as possible in your design.\u003c/p\u003e\n\u003cp\u003eTypically, you would expect the publisher to have direct knowledge of each of the many subscribers that it needs to notify, so it can go about notifying each of them, once the \u0026ldquo;event\u0026rdquo; or message is ready. But with an event bus, the publisher is relieved of such duties and this independence helps, because the publisher and subscriber need not have logic coded in them that establish the dependencies between the two.\u003c/p\u003e\n\u003cp\u003eIn other words \u0026ldquo;consciously decouple\u0026rdquo; your code whenever you can*.\u003c/p\u003e\n\u003ch2 id=\"how-the-anonymity\"\u003e\n How the anonymity?\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#how-the-anonymity\" aria-label=\"Link to How the anonymity?\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eOk, so a natural question with the pub-sub pattern is: how do you actually achieve that anonymity between publisher and subscriber?

The tl;dr version of this post is: get good at story telling.

You might some of the stories interesting:\u003c/p\u003e\n\u003c!-- more --\u003e\n\u003cp\u003ePresentations are generally looked at with much anxiety and trepidation (within the tech community at least). There are two ways to combat this:\u003c/p\u003e\n\u003col\u003e\n\u003cli\u003ePractice like crazy (joining a group like Toastmasters helps)\u003c/li\u003e\n\u003cli\u003eHave something interesting to say.\u003c/li\u003e\n\u003c/ol\u003e\n\u003cp\u003eObviously, you have to do both to become a good presenter, but I want to focus more on the latter point. You know what most human beings find interesting? Stories! Even crappy ones. We\u0026rsquo;re wired from birth to like stories. If i heard two presentations, both of mediocre quality, i would definitely prefer the one that had a story to tell. I think stories make your presentations more personal and relatable. Heck, it doesn\u0026rsquo;t even have to be your own. People relate more easily to stories because they feel they can associate themselves with your pain/experience. A \u003ca href=\"http://ninjasandrobots.com/lead-with-pain\"\u003epost on ninjasandrobots\u003c/a\u003e (how cool is that domain name!) talks about leading with pain. It boils down to telling a story.\u003c/p\u003e\n\u003ch2 id=\"using-stories-to-captivate\"\u003e\n Using stories to captivate\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#using-stories-to-captivate\" aria-label=\"Link to Using stories to captivate\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eIf you tell a great story, then it sticks. I have a professor here in CMU, that uses this tactic and boy is it mesmorizing. It totally helps that he\u0026rsquo;s got the experience (MIT, previous CTO of the research dev labs of a tech giant that makes phones etc. Hint: if you\u0026rsquo;ve used a mobile phone in the past 5-8 years, you have definitely used his ex-company\u0026rsquo;s phones). We were working on a project with him on collecting sensor data. He gave us an example of how data is always valuable. The only problem, is that the value of that data is realized at a different time.\u003c/p\u003e\n\u003cp\u003eHe gave us this example: the fire department had a service where people could call in emergencies, along with pictures of the site. You can\u0026rsquo;t really control the inflow of data with the public, so you had people sending in pictures of dead cats around the city. Yes this was tragic, but there isn\u0026rsquo;t really much a fire department can do now with this info right? Yes and No. A few weeks later, there was an anthrax scare in the city and it was extremely important for the HAZMAT department to find the source of the outbreak. You know which creatures are most sensitive to anthrax? cats. Suddenly those dead cat pictures became tremendously useful, in tackling a major disease outbreak. That story was one of the many, that our professor told and mesmorized us into working on his project (note to self: write more posts about those stories).\u003c/p\u003e\n\u003ch2 id=\"improving-your-memory\"\u003e\n Improving your memory\n \u003ca class=\"heading-anchor static ml-2 inline-block whitespace-nowrap md:absolute md:right-full md:top-0 md:ml-0 md:mr-2 opacity-30 hover:opacity-100 focus-visible:opacity-100 transition duration-200 no-underline text-ht-lighter hover:text-hc focus-visible:text-hc font-normal\" href=\"#improving-your-memory\" aria-label=\"Link to Improving your memory\"\u003e##\u003c/a\u003e\n\u003c/h2\u003e\n\u003cp\u003eI gave this goofy presentation on \u003ca href=\"http://en.wikipedia.org/wiki/Rock-paper-scissors-lizard-Spock\"\u003eRoshambo 2.0\u003c/a\u003e (the lizard-spock variant popularized by The Big Bang theory) once and obviously the presentation required that I get the sequence right. It\u0026rsquo;s pretty tricky, even Sheldon \u003ca href=\"http://www.youtube.com/watch?v=tCNxvsP-Ce8\"\u003egot it wrong\u0026hellip;\u003c/a\u003e \u003ca href=\"http://www.youtube.com/watch?v=Z2z-AbYMk5Q\"\u003emultiple times\u003c/a\u003e. This was sort of a lightening talk I had to give at school and it was a casual setting, which meant the audience were my friends and they would totally rip me apart if I got it wrong. I thankfully got it right in one shot :D and it didn\u0026rsquo;t really matter if my delivery style, poise, body language etc. was great. My presentation was a success mostly because I got it right in one swoop. People came up to me and asked if i had a photographic memory? It\u0026rsquo;s actually quite the opposite. I have a horrible memory. Close friends know that I have the admirable feat of genuinely forgetting my own birthday one year (if my dear folks and brother hadn\u0026rsquo;t reminded me at 12:00am, I would have probably gone through the whole day not realizing I clocked another year). Digression aside, the way I managed to get Roshambo 2.0 right was that I weaved a crazy story in my head to follow the sequence. If you \u003cem\u003earen\u0026rsquo;t\u003c/em\u003e interested in the story that I came up with, skip the next paragraph (why did you start reading this post though?).\u003c/p\u003e\n\u003cp\u003eI imagined myself starting with a pair of scissors cutting paper.I look at the paper and then realized i had used that to cover a rock once, the same rock that I used to chuck at a lizard. That pesky lizard was a blue necked one, similar to the one that poisons Spock in a fictional Star Trek episode. In that fictional episode, Spock was so mad with Kirk\u0026rsquo;s tomfoolery, that he chucks a scissor at Kirk, but misses and lands up breaking it. Kirk to make up for his actions, decides to kill/decaptiate the same blue necked Lizard(that poisoned Spock), with a scissor. During the battle, the Lizard needed nutrition, so it decides to eat paper. In a crazy twist of serendipitous circumstances, the paper consumed was the same one that Kirk initially wrote to disprove Spock, in an experiment Spock was doing, to vaporize Rock. Oh and Rock beats Scissors. The key here is to make your own story cause this might make no sense at all, but in my head I can see the whole story playing out crystal clear.\u003c/p\u003e\n\u003cp\u003eIt\u0026rsquo;s magical how stories can greatly help improve memory. I\u0026rsquo;m pretty sure there are scientific studies conducted by people far more experienced and knowledgeable than me, proving this point but Roshambo 2.0 was proof enough for me.\u003c/p\u003e\n\u003cp\u003eIf you\u0026rsquo;re not as excited as you were led to believe reading this post, I leave you with links to presentations given by the masters.
