of the Future

What is Rust?Main features and industry adoptionA quick tour of the languagePlatforms and development toolsCargo and CratesUseful packages and tools for Infobip's businessAdvantagesDisadvantagesResources and local community!

I'll try to show:what are Kotlin-coroutinesProblems with project reactor:why it is hard (requires a lot of knowledge to use properly)why it is not readableKotlin coroutines as a rescue!

As a result of 1# innovation hack days (2nd place) we have demonstrated what WebAuthn technology is, how it works and how we can integrate it into our portal.infobip.com.Agenda (Draft):What is WebAuthnIntro to public key cryptography and digital signaturesSignup without passwordLog in to portal without passwordAdditional factors (Fingerprint, Face recognition, USB key)Security implications (Why this is more secure than password)Summary and conclustion

Permissions, features, roles, teams, so many things.Why can't my account see anything, what is different between account and user permissions?How to create new permission?Can I have role with specific permission?We will try to decipher all this pain points.

Challenges that come with organizational scaling and maintaining a monolith. Business decision to opt for service extraction (beware the term microservices is coming) which led to many difficulties along the way:Bounded context extractionEdgy featuresMaking changes on live code without downtimeInitial extraction conclusionsIncremental improvementsMissing stepsThis was the first domain that was extracted and there are many to come, so this was not only a test can it be done but also a blueprint for future extractions.

A little showoff of javascript (vanilla so no frameworks etc) how to work with javascript on the fly, how to debug it, how to trick it, what is it, what power opportunities it can give it to u, how to work with console. What will you see:a short explanation what is javascripthow to work with chrome consolevalidation failures - why this is only for ui experiencehttp calls on the fly from your consolewhy escaping js is important while u allow users to put some content to ur web / app - samplejavascript weird stuff

A actual Infobip case study for the hunt for the threat actor that compromised seamlessly random CUP accounts to send large value of traffic in 2020. How tracked, identified and what did we do to protect Infobip platform.

How to measure end to end latency of some request through services and detect internal and external contributors.Endgoal here isto monitor SLA commitment for important clientsget overview of each service for all data paths through it for various request types minimize false positives caused by latencies introduced by external factors to have view of IB platform as black box, how clients see itHands on demonstration how this was achieved for SMS message going through SMPP Balancer, IpCore and GW proxy.Will be described in more details here, still under construction"."

If at first you don’t succeed, trie, trie again
Imagine rolling out new version of your service, working on compatibility, porting features, migrating clients over. This time you started with documentation first approach, learned from mistakes of the old service, automated everything upfront. All the good stuff!Only to find out, as more and more of your users migrate over, that the new service has terrible scaling characteristics. Once all clients are moved over, new service is over 10 times slower than the old one.This is a story of how we diagnosed the performance problem and used some good old Computer science to fix it!

Docker image layers with jib - 2 years later
Two years ago we started using google jib maven plugin to package our infobip java service docker images. How does it look after 2 years? Did we get what we aimed for? Is it useful and how?

How voice on IO became reality
For a log time, voice services like text to speech messages, IVR, number masking, etc. were not possible on IO environment. Join me in this session to find out what it took to make it possible and how we are simulating Mobile Network Operator.

Executive Function - Bringing Awareness
Focusing on disability surrounding Executive Function, and how it affects me with cognitive flexibility, working memory, and inhibitory control

Imagine a scenario where reliable Service you've been calling for quite some time decides to go for a nap. Or vacation. Or both.What happens to your service? Do you need to protect it from sudden outages? And how?In this presentation, I'm going to share experiences with Circuit Breakers by trying to answer the most common questions: What? Why? How? Where?

Lessons learned" talk about migration of Pushko service from Redis high availability (HA) to RabbitMQ HA solution. Showcasing some issues we encountered and solutions for them we will reiterate on the importance of:- learning about all configuration options for particular HA solution before making design decisions- doing a proper proof-of-concept, stress testing it and evaluating its performance/availability in as much production-like environment as possible- preparing to deal with the fact that complexity grows exponentially for distributed systems"

Blockchain 101 and stuff. Technical and social aspects.

The OpenMarket Data team would like to show some of the tools and systems we've been using in our newest platform to solve the age old question of how do we generate value for our customers from all this data we have. Topics to include:

Creating horizontally scalable data solutions
Creating compelling customer reports
Giving internal customers powerful tools to do data analytics, data mining, and comprehensive reporting, to serve our customers well

UX values and concepts applied to life and work. Metaphors + examples and more.

In the era of SaaS products, having a great UI/UX design is a must. But also not making mistakes while implementing that design... In this session, I will show some simple things that if not implemented correctly can turn a great product into a poor one.

Everything today has room for improvements, but what do we need to think about when working on the projects? We need to make sure that our projects are stable and resilient! The important thing is that all issues and problems we stumble across can help us learn something for the future and give us the possibility to improve our products. Join your jaran/munja around the campfire as in this session I am gonna tell you seven CUP/Infobip Portal (horror) stories about the issues we have faced, how we solved them, and what we have learned from this.

Why do we have ADR7 and what does it mean 'building crossdc/regional' services? How does it complicate development and operation of our products? What do we need to know before writing any code? What to do with existing services? What should and what actually happens when we switch traffic to another datacenter? Is switching traffic same as switching customer datacenter location? How to survive disaster recovery testing? Hopefully some possible solution patterns will be presented that we can discuss.
