The Federal Trade Commission and the Utah Division of Consumer Protection have named two additional defendants in their case against the operators of the Zurixx real estate investment training scheme. The FTC and the Division allege that Zurixx used deceptive promises of big profits in live sales events and telemarketing to lure consumers into spending thousands of dollars on Zurixx’s products and services. The second amended complaint adds Utah-based CAC Investment Ventures, LLC as a defendant in the case, and Stephenie Spangler as a relief defendant, meaning that she is not accused of wrongdoing but allegedly received funds that Zurixx illegally obtained from consumers. The FTC and the Division sued Zurixx in October 2019 and first amended their complaint in May 2020. The Court has issued a stipulated preliminary injunction against defendants. The receiver in the case has created a website with information for consumers who may have been affected at www.zurixx.com . Consume

FTC to Hold Virtual Workshop Exploring Digital “Dark Patterns”

The Federal Trade Commission will host a virtual workshop on April 29, 2021 to examine digital “dark patterns,” a term that has been used to describe a range of potentially manipulative user interface designs used on websites and mobile apps. “Bringing Dark Patterns to Light: An FTC Workshop” will explore the ways in which user interfaces can have the effect, intentionally or unintentionally, of obscuring, subverting, or impairing consumer autonomy, decision-making, or choice. For example, some sites sneak extra items into a consumer’s online shopping cart, or require users to navigate a maze of screens and confusing questions to avoid being charged for unwanted products or services. The FTC workshop will bring together researchers, legal experts, consumer advocates, and industry professionals to examine what dark patterns are and how they might affect consumers and the marketplace. Some of the topics the workshop will examine include: how dark patterns differ from sales tactic

DynamoDB concepts

Table: A collection of DynamoDB data records. Item: A single data record in a DynamoDB table. It is comparable to a row in a relational database. Attribute: A single data element on an item. It is comparable to a column in a relational database. However, unlike columns in a relational database, attributes do not need to be specified at table creation, other than the primary key. Attributes can be simple types such as strings, integers, or Boolean, or they can be complex types such as lists or maps. Primary key: A primary key is a unique identifier for a single item in a DynamoDB table. The primary key name and type must be specified on table creation, and a primary key of the specified type must be included with each item written to a table. A simple primary key consists of a single attribute, and a composite primary key consists of two attributes: a partition key and a sort key. For example, you can create a simple primary key using “UserID” as an identifier, or create a composite pri
