Sigma

The younger generations lingo can be a bit confusing, new words and phrases are constantly being born such as “rizz,” “gyatt” and “fanum tax” (who actually knows what that means?)  Most of these words come from TikTok, or were at least made popular there; its never-ending stream of short-form content means that new slang catches on pretty quick. The word “sigma” is used frequently on the app, but what does it mean? To answer the question requires doing a deep dive into multiple topics, including incel culture and the…

The Maruti Suzuki Baleno is one of the most popular premium hatchbacks currently on sale in India, and ever since its launch, the company has sold a ton of them. The Baleno is offered by Maruti Suzuki in four main variants: Sigma, Delta, Zeta, and Alpha. While many people opt for the top-spec variants, a ton of people choose the budget-friendly Sigma variant. Recently, an owner of a Sigma variant transformed the look of his base variant car into something extremely different. The owner of this particular hatchback has…

Since its launch, Maruti Suzuki India Limited’s crossover Fronx has garnered a lot of interest in the country, as the largest carmaker. Many people are comparing this new crossover with some of its siblings to understand its position in the brand’s lineup in India. One of the most requested comparisons is with its hatchback counterpart, the Maruti Suzuki Baleno. In a recent video, a YouTuber has done the same thing and has compared the base Sigma variants of both the Baleno and Fronx. Prince Joshi shared the video of…

Maruti Suzuki has recently revealed the pricing of their brand-new Fronx, and soon after the announcement, all the variants of the car started arriving at dealerships. A video walkaround showcasing all the details of the base Sigma variant has been shared on YouTube. In the video, the presenter shows the Fronx Sigma variant from the exterior and interior, providing all the details of on-road pricing and features. The video of the Fronx base variant has been shared by Power Racer on their channel. The video starts with…

To boost performance, we implement a forgetful bloom filter and a custom Spark state store providerPhoto by Leora Winter on Unsplash, Shippagan, NB, CanadaThis is the 5th article of our series. Refer to part 1 , part 2, part 3 and part 4 for some context.In our previous articles, we have demonstrated the performance gains achieved by using a bloom filter. We also showed how we leveraged a bloom filter to implement temporal proximity correlations, parent/child and ancestor relationships.So far we have been using a single…

We implement a Spark structured streaming stateful mapping function to handle temporal proximity correlations in cyber security logsImage by Robert Wilson from PixabayThis is the 4th article of our series. Refer to part 1 , part 2 and part 3 for some context.In this article, we will detail the design of a custom Spark flatMapWithGroupState function. We chose to write this function in Scala since Spark is itself written in Scala. We named this function Flux Capacitor. Electric capacitors accumulate electric charges and…

Last year, Marvel published Star Wars: Revelations #1, stating "Meet AJAX SIGMA, a droid unlike any other." Today, Marvel promises more...It's Ajax Sigma time! In today's Star Wars #32 from Marvel Comics, Luke Skywalker is slaughtering droids. Because in the Star Wars universe, that sort of thing is just fine. Star Wars #32 But might there be some dark foreshadowing here? Star Wars #32 Because something big is on the way. Marvel Comics published Star Wars: Revelations #1 in November last year, which teased the future of…

Tesla Inc. has been weighing a takeover of battery-metals miner Sigma Lithium Corp., people with knowledge of the matter said, amid rampant demand for the metal used in electric vehicle batteries. The EV maker run by Elon Musk has been speaking with potential advisers about a bid, said the people, who asked not to be identified discussing confidential information. Sigma Lithium is one of multiple mining options Tesla is exploring as it mulls its own refining, one of the people said.Sigma’s US shares surged more than 25%…

Can a custom tailor made stateful mapping function based on bloom filters outperform the generic Spark stream-stream join?Photo by Kalpaj on Unsplash, Peggys Cove, NS, CanadaSpark’s flatMapGroupsWithState function allows users to apply custom code on grouped data and provides support to persist user defined states.In this article, we will implement a stateful function that retrieves the tags (features) of a parent process. The crux of the the solution is to create a composite key made of the process ID (e_key in the…

A class of Sigma rules detect temporal correlations. We evaluate the scalability of Spark’s stateful symmetric stream-stream join to perform temporal correlations.Photo by Naveen Kumar on UnsplashFollowing up on our previous article, we evaluate Sparks ability to join a start-process event with it’s parent start-process event.In this article, we evaluated how Spark stream-stream join can scale. Specifically, how many events can it hold in in the join window.During our research, we evaluated a few approaches:Full joinDoing…
