Why This Piece Exists of the Fourier Transform — more like an intuition piece based on what I’ve learned from it and its application in sound frequency analysis. The purpose here is to build intuition for how the Fourier Transform helps us get to frequency domain features from time domain features. We won’t get into heavy math and derivations; instead, we’ll try to simplify the meaning conveyed by the complex equations. Before we get into the Fourier Transform, you should have a basic understanding of how digital sound is stored — specifically sampling and quantization. Let me quickly cover it…

Just align your sales, marketing, and customer success teams around a shared set of data and goals. Done. Next slide. And yet, in practice, it becomes impossibly complex, like trying to understand why Pete Davidson is so attractive to beautiful women.Automate your RevOps workflows for better customer experiencesThe good news is that RevOps tools…

Iranian-Linked Threat Actors and TTPs Targeting Financial Services in EuropeGiven the escalating conflict between Iran, Israel, and the US that began on February 28, 2026, European financial services organizations face a multi-directional threat landscape from both state-sponsored APTs and proxy hacktivist groups.Key Threat Actors to Monitor#1: Seedworm / MuddyWater (Static Kitten) – Symantec researchers identified Iranian APT group Seedworm conducting intrusion operations against multiple U.S. organizations beginning in early February 2026, with targeted entities including a U.S. bank, software company, airport, and NGOs in the U.S. and Canada. This direct targeting of a bank demonstrates clear intent to compromise financial…

Yahoo today introduced MyScout, a customizable homepage inside Yahoo Scout, its beta AI answer engine. How MyScout works. Logged-in users can customize the homepage with tiles that pull information from Yahoo properties (e.g., Mail, News, Sports, Finance, Games). Examples include: Inbox previews from Yahoo Mail. Stock updates from Yahoo Finance watchlists. News topics and trending stories. Scores and schedules for favorite teams. Weather, shopping comparisons, and games. Users can add, remove, reorder, or create tiles based on topics or queries they want to follow. Some tiles update in real time, such as stock prices. Other tiles refresh throughout the day…

You wake up on Easter Sunday ready to conquer the annual egg hunt, but first comes Easter brunch. Croissants, waffles, quiche, a sparkling wine cocktail: the kind of fuel you’ll need for the festivities ahead.Easter dinner may bring braised leg of lamb and maple-roasted carrots, but brunch sets the tone for the day. It’s your excuse to eat fried eggs and chocolate before noon. Our best Easter brunch recipes (egg bakes, coffee cake, pancakes, and plenty of spring produce) will help you build the perfect holiday spread—and maybe reclaim that Egg King title your nephew stole from you last year.

For years, communications and PR teams have warned that their budgets are under threat. In 2026, that warning has become a reality. According to industry research, budget pressure remains one of the top concerns for communications leaders, largely because executives still struggle to understand how PR contributes to business outcomes. As Katie Paine bluntly says, when leadership can’t see value, communications is treated as an expense, not an investment. At the same time, digital marketers face a parallel challenge. AI-driven search, zero-click answers, and opaque attribution models have made it harder to explain where demand actually comes from. Google Analytics 4…

If you use Buffer, then you’re familiar with our Composer. It’s where every post begins. Where you draft, tweak, preview, and hit publish. It’s the most-used surface in the entire product, and it’s the core of our value. For a while now, though, the composer has been showing its age. Not necessarily to users (it worked!), but under the hood, it was built on legacy code that made it increasingly difficult to maintain, improve, and extend. Every small change carried risk. Every new feature required navigating layers of complexity that slowed us down. So we decided it was finally time to…

and eigenvectors are key concepts in linear algebra that also play an important role in data science and machine learning. Previously, we discussed how dimensionality reduction can be performed with eigenvalues and eigenvectors of the covariance matrix. Today, we’re going to discuss another interesting application: How eigenvalues and eigenvectors can be used to perform spectral clustering, which works well with complex cluster structures. In this article, we’ll explore how eigenvalues and eigenvectors make spectral clustering possible and why this method can outperform traditional K-means. We’ll begin with a simple visualization that will show you the importance of spectral clustering and…

Twitter is now X, AI is everywhere, Threads is a thing, LinkedIn is back, and TikTok had a big will-it-be-banned-won’t-it-be-banned fandango. But what the chaos has shown is that despite everything, social media is still one of the most powerful tools available to modern businesses. You can use it to find new clients, drive traffic to your site, and keep in touch with existing…
