Elixir, Erlang, and Cucumberl Elixir is a new Ruby-inspired programming language that uses the powerful concurrent machinery of Erlang behind the scenes. Cucumberl is a port of Cucumber to Erlang. Let's see what happens when we put them together. In this talk, we'll discuss: How Erlang's concurrency makes it easier to write robust programs Elixir's approachable syntax How to test Erlang and Elixir programs using Cucumberl Attendees will walk away with a solid introduction to the principles of Erlang, and an appreciation of the way Elixir brings the joy of Ruby to the solidity of the Erlang runtime.

If you want to program a parallel computer, it obviously makes sense to start with a computational paradigm in which parallelism is the default (ie functional programming), rather than one in which computation is based on sequential flow of control (the imperative paradigm). And yet, and yet ... functional programmers have been singing this tune since the 1980s, but do not yet rule the world. In this talk I’ll say why I think parallelism is too complex a beast to be slain at one blow, and how we are going to be driven, willy-nilly, towards a world in which side effects are much more tightly controlled than now. I’ll sketch a whole range of ways of writing parallel program in a functional paradigm (implicit parallelism, transactional memory, data parallelism, DSLs for GPUs, distributed processes, etc, etc), illustrating with examples from the rapidly moving Haskell community, and identifying some of the challenges we need to tackle.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “Enterprise Knowledge Graphs: The Importance of Semantics” on May 9, 2024, at the annual Data Summit in Boston. In her presentation, Hedden describes the components of an enterprise knowledge graph and provides further insight into the semantic layer – or knowledge model – component, which includes an ontology and controlled vocabularies, such as taxonomies, for controlled metadata. While data experts tend to focus on the graph database components (RDF triple store or a label property graph), Hedden emphasizes they should not overlook the importance of the semantic layer.

I'm excited to share my latest predictions on how AI, robotics, and other technological advancements will reshape industries in the coming years. The slides explore the exponential growth of computational power, the future of AI and robotics, and their profound impact on various sectors. Why this matters: The success of new products and investments hinges on precise timing and foresight into emerging categories. This deck equips founders, VCs, and industry leaders with insights to align future products with upcoming tech developments. These insights enhance the ability to forecast industry trends, improve market timing, and predict competitor actions. Highlights: ▪ Exponential Growth in Compute: How $1000 will soon buy the computational power of a human brain ▪ Scaling of AI Models: The journey towards beyond human-scale models and intelligent edge computing ▪ Transformative Technologies: From advanced robotics and brain interfaces to automated healthcare and beyond ▪ Future of Work: How automation will redefine jobs and economic structures by 2040 With so many predictions presented here, some will inevitably be wrong or mistimed, especially with potential external disruptions. For instance, a conflict in Taiwan could severely impact global semiconductor production, affecting compute costs and related advancements. Nonetheless, these slides are intended to guide intuition on future technological trends.

Are you wondering why everyone is talking about the Flutterwave scandal? You’re not alone! It’s been in the news a lot. We’re going to tell you all about the Flutterwave Scandal in a way that’s easy to get. Keep reading, because we’re going to share the whole story with you. The company Flutterwave is headquartered in San Francisco, California, United States. In 2016, Iyinoluwa Aboyeji, Olugbenga Agboola, and Adeleke Adekoya established Flutterwave. It offers a payment infrastructure to international merchants and payment service providers throughout Africa. The company operates in various African countries including Nigeria, Kenya, Uganda, Ghana, South Africa, and others. They focus on digital payments, helping businesses accept and process payments on various channels like the web, mobile, ATM, and POS. Recently, they’ve been in the news due to allegations of misconduct within the company, which has affected their reputation and value. Flutterwave is an essential player in the African fintech landscape, aiming to drive growth for banks and businesses through digital payment solutions. The Flutterwave scandal involves allegations of misconduct and inappropriate behaviour towards female employees by the company’s co-founder and CEO, Olugbenga Agboola. Reports have surfaced from both current and former employees about bullying, intimidation, and sexual harassment at work. The allegations of inappropriate behaviour towards female employees at Flutterwave, specifically involving the CEO Olugbenga Agboola, were brought to public attention in April 2022.This was when Clara Wanjiku Odero, an ex-employee and current CEO of Credrails, published a Medium post and a series of tweets on April 4, 2022, accusing Flutterwave and Agboola of bullying. These allegations were part of a broader range of misconduct claims that surfaced around the same time The reasons behind the scandal are rooted in accusations of unethical behavior within the company. The allegations suggest a workplace culture that allowed for misconduct and failed to protect employees from harassment and intimidation. Specifically, the Flutterwave scandal refers to the series of events where the CEO was accused of engaging in improper conduct with female colleagues. This led to a broader investigation into the company’s practices and raised serious concerns about the fintech’s corporate governance. The scandal had significant repercussions, including a drop in the company’s stock price and a loss of trust among customers and partners. The trust that customers and investors had in Flutterwave was greatly damaged. People started to doubt the company’s integrity and whether their money and personal information were safe. Market Impact The scandal shook the entire fintech market. Flutterwave’s competitors saw this as an opportunity and started to attract customers who were leaving Flutterwave.
