With the growth in the number of electric and autonomous vehicles, where the vast majority of components are built on software, the amount of code in a vehicle is only going to increase. Connectivity, both within the vehicle and outside, is also increasing, meaning that the security of these systems has become more critical than ever before. For any system where there is communication between components or with the outside world, there is an increase in possible software cybersecurity threats.

Working with complex nested data objects can be difficult, especially when accessing a specific property or subset of data in a complex data structure. This post will look at complex data objects, what they are, and an easier way of managing those complex data objects by using complex types.

Exceptions are unintended events that take place when a program is being executed or during its runtime causing disruptions to the program's overall logic. In Ruby, a program is enclosed between the begin and end blocks and a rescue block is used to tell what types of exceptions are to be handled. When no class is specified, by default, a RuntimeError is raised by Kernel#raise.

The ActionController::UnpermittedParameters error occurs when a parameter that has been passed is not permitted in a create, an update, or a user-defined action. In older versions of Rails, information about the unpermitted keys was provided in the logs only when an unpermitted parameter was found in a request. This did not provide enough information for the developers to understand which controller and action received the unpermitted parameters.

Built with BigQuery: How Tamr delivers Master Data Management at scale and what this means for a data product strategy

Once a customer is ready to purchase, the final frontier lies ahead: the payment process. Because online transactions already come fraught with a learning curve, companies must use extensive payment gateway testing to deliver frictionless payment experiences. Even minor glitches can cause cart abandonment and reduce sales volume. Where other aspects of software may enjoy the leeway to go live while minor problems are ironed out, payment gateways cannot afford anything less than perfect reliability.

Do you look at spreadsheets with analysis paralysis? This article will help you simplify the entire process — forever.

There are few topics in the world right now that are hotter than data and its related fields. As technology, machine learning, and computer algorithms continue to expand, so does the way that companies can use this information to benefit their business. Extract, Transform, and Load (ETL) remains one of the most important processes in the area of big data. This area is absolutely booming, and so is the demand to learn more about its various processes and components.

Multivariate time series forecasting allows BigQuery users to use external covariate along with target metric for forecasting.
