Markets are priced by people, and people swing between two emotions: the fear of losing money and the greed to make more of it. The CNN Fear & Greed Index is an attempt to compress that emotional state into a single number between 0 and 100 — 0 being maximum fear, 100 being maximum greed, 50 being neutral. It is one of the most-watched sentiment gauges in retail and professional finance, and one of the most misunderstood.

The Cboe Volatility Index is the most quoted and least understood number in financial markets. It is cited daily as the market’s “fear gauge,” yet most of the commentary surrounding it treats the index as a sentiment poll rather than what it actually is: a precise, formula-driven measurement of the price of insurance on the S&P 500. Understanding the distinction is the difference between using the VIX as a tool and being used by it.

Bitdefender has released its 2026 Global Scam Intelligence Report, a 12-month analysis of the global scam landscape built from trillions of URLs, billions of messages, and live ad ecosystem telemetry — finding that 14% of consumers fell victim to a scam in the past year and that finance-themed fraud now dominates every major communication channel. The report is the most data-dense scam analysis Bitdefender has published to date. Its telemetry infrastructure spans call honeypots, direct consumer submissions, and live ad ecosystem monitoring, capturing campaigns in motion rather than reconstructing them post-incident.

The case for owning Marvell almost always opens with custom AI chips, and that is the part of the story where Marvell is structurally second. The company and Broadcom are the two names that turn hyperscaler in-house silicon designs into manufacturable chips, the application-specific processors that Amazon, Microsoft, Google and Meta increasingly favor over off-the-shelf GPUs for inference. But Marvell holds roughly 15 percent of that market against Broadcom’s 55 to 60 percent, and Counterpoint expects Broadcom to command about 60 percent of custom AI silicon by 2027.

WiGig had a brief moment of consumer visibility around 2017 to 2019. A handful of laptops from Dell and Lenovo shipped with 60 GHz modules. A small number of docking stations used WiGig to replace the DisplayPort and USB cables between a laptop and a desk setup. Then it went quiet, consumer products quietly discontinued, and the technology receded from mainstream WiFi discussions. The conclusion most drew was that WiGig had failed.

In a multi-AP WiFi environment — a mesh system, an office with multiple access points, or a home with a router and a range extender — the experience of moving between access points defines the quality of the whole system. A phone call that drops when you walk from the kitchen to the garden is not a signal problem; it is a roaming problem. Three 802.11 protocol amendments, operating together, are the mechanism that makes roaming fast enough to be invisible.

Two products solve the same problem — covering a large or multi-story home with consistent WiFi — from different engineering philosophies. Mesh systems optimize for installation convenience and seamless roaming. Multi-AP systems using wired backhaul optimize for raw performance and reliability. Which is better depends almost entirely on what your home’s infrastructure looks like and how much the installation process matters. The Single Router Problem A single router positioned in one location covers a sphere of radio energy that attenuates with distance and obstacle density.

The spec sheet for a Raspberry Pi reads like a modest embedded processor. What people actually build with one reads like an infrastructure engineer’s fever dream. Over the years, the platform has accumulated a body of real-world deployments that range from cost-effective home network appliances to production-grade industrial monitoring systems. This post examines a cross-section of those deployments — not hobbyist proof-of-concepts, but functioning systems solving real operational problems. The case studies below span home labs, small businesses, agriculture, aviation, scientific research, and industrial environments.

Router placement is the cheapest performance upgrade available to any WiFi user. It costs nothing and the impact on signal coverage and quality in a typical home is significant — often more significant than upgrading to the next generation of hardware. The principles are simple and rooted in the same physics that governs all radio propagation. The Inverse-Square Law and Height A router transmitting from floor level radiates radio energy outward in all directions.

An accordion feature — also called an incremental facility — is a provision in a credit agreement that allows the borrower to increase the size of the existing loan facility without negotiating a new credit agreement. Like the instrument it is named for, the facility can expand when the borrower needs more room. What It Is When a company closes a syndicated credit facility, it typically negotiates a maximum size — a term loan of $500 million, for example, or a revolving credit facility of $250 million.
