Reversim Podcast

In this talk we'll take a hard look at one of the most commonly used, and at least as commonly misunderstood, elements in software engineering: time. Time is so fundamental to the way humans experience reality that we don't normally give it a second thought, but it's just as fundamental to software systems. Without a correct model for working with time BAD THINGS HAPPEN: data is persisted out of order, exceptions occur where they shouldn't be possible, and production systems blow up.We'll cover the various common representations of time, acknowledge their caveats and deficiencies, and hopefully learn a few new tools and practices along the way.MP3

פודקאסט מספר 359 של רברס עם פלטפורמה - אורי ורן מארחים את ארז ברקנר לשיחה על עננים נטולי שרתים (Serverless . . .), א-סינכרוניות ואנטי-חומר.לפני הכל, חדשות מרגשות - כנס רברסים השביעי (Reversim Summit 2019) יוצא לדרך!כן, כבר - 17-18 ביוני 2019, הצוות מתחיל להתאסף, ואם אתם (או אתן, או החברות שאתם עובדים בהן) רוצים להיות ספונסרים ולהתחבר לכנס הנפלא הזה, רוצו לתפוס מקום  ממש עוד מעט יפתח גם ה -  Call for Papers - אם יש לכם סיפור מעניין, אנחנו רוצים לשמוע, זה המקום. אם חיפשתם רעיונות ליעדים לשנה החדשה, הרצאה בכנס (או לפחות הגשת הצעה רשמית) יכולה להיות אחלה אופציה.אז איפה הסרבר שלי?ארז מפתח כבר הרבה שנים, התחיל בתור ילד בין 10 עם Commodore 64 ותכנות בבייסיק; תואר ראשון בזמן התיכון ושירות צבאי ביחידה טכנולוגית של משרד ראש הממשלה (בטח מותג מחדש מאז כ - Data Science).אחרי הצבא, הרבה שנים (14) ב - Check Point (בהתחלה כמפתח קרנל של Linux), שם גם נוצר הקשר עם אביעד מור, היום השותף (וה-CTO) ב-Lumigo.פגישה עם עולם ה-Serverless דרך עולמות ה-Cloud (ארז) וה - Emerging Technologies (אביעד), וב-2017 מעבר והקמה של -Lumi

In the last decade, the centrality of front-end components vastly growing. Developing front-end in a large scale requires declarations and enforcement of principles and guidelines for keeping the code maintainable, extensible and stable. My talk main notion is to introduce the S.O.L.I.D principles within the context of front-end components. I will discuss the reasons for implementing the S.O.L.I.D principles in our renew web applications as a comparison to our starting point. I will suggest guidelines based on my interpretation of S.O.L.I.D in the front-end world. I will enrich the discussion by supplying various practical examples regarding the guidelines implementation.MP3

In our industry, there is a clear differentiation between B2C and B2B. And while the business models and sales funnel can be different, we tend to have a different approach in terms of UX and product. But, why?The people that are using our products don't stop being consumers the moment they enter their office, and the high level experience they are expecting from the apps in the their pocket don't disappear when they sit on their desks. In this Lightning talk I am going to share some examples, the lessons I learned from working in a startup that creates medical devices for doctors and nurses all around the world, from Africa to the USA.MP3

At last year's Reversim, Iftach Bar gave a beautiful talk called “Lets talk about your salary”. He taught engineers how to negotiate their salaries when getting hired. But while salary negotiation is hard for candidates, it's practically a nightmare for employers. When we hire we're faced with the impossible task of evaluating the potential value of a perfect stranger to our company, knowing that the cost of being wrong could be extremely high (especially for startups). In this presentation I will share how at BigPanda we try to minimize that risk so that eventually both sides are happy. It'll also give candidates a chance to better understand how managers think when making offers.MP3

Our product wasn't complete without this one feature, so we went ahead and built it. Soon enough we came to realize users didn't use it, and even worse, they were still feeling the pain we planned to solve. We ended up finding ourselves in a situation where we had to rebuild a fresh feature from scratch. This experience thought us some good lessons that would should be heard by anyone building anything.MP3

The graphdb world hasn't changed much for the past couple of years, the same major players applying the same old know techniques, when I started creating my own version of a graph database, I followed the same path, but to make a difference and really standout in the crowd something had to be done differently. This talk will introduce you to and guide you through what I've learnt in the past two years creating the fastest graphdb today using basic mathematics, I hope your linear-algebra is polished! MP3

This is a lightweight, (hopefully) entertaining talk, in which I will present insights and anecdotes from my studies in a laboratory that combines artificial intelligence with human-computer collaborations, and how I got to intentionally stumble into people. This talk will include a call for innovations in the border between humans and computers.MP3

As product managers, our biggest fear is creating a product that nobody needs. So, how to make sure your users will want your product?In the B2C world, you have to be both data-driven and customer-centric. To make your product better, you need to:Collect input from usersUnderstand why users churn or stayApply that data using MVP and fast iterationsWe tried at Soluto different ways to collect data in the right time and context. I would like to share with you what we did and learned in the process, show methods to collect user input, what worked and what didn’t. I will also showcase examples of how to use the data and create a product your users will actually use - and love.MP3

It still amazes me to see the basic security flaws over and over again on every site that I check, All of those security breaches can be prevented and closed quite easily. In this talk, I will explain and show basic security flaws in web applications - how to detect those and how to make sure that your application or web site will not have those.MP3
