Machine Learning Displaying a Formula

I am realizing that machine learning likes mathematical notation. Time to figure out how to put a formula in a post. Since the 1980s, the go-to tool for publishing mathematical papers has been     It has a cool history, but to write my study notes, I just needed to figure out how to use […]

ACE Exam Billing Basics

Creating billing accounts and linking them to projects present no real difficulties. It seems important to recognize that a billing account and a payment profile are not the same. The billing account resides inside GCP, but the Payment Profile exists in a separate Google entity. The payment profile processes payments for any Google services. The […]

Machine Learning Three Algorithms

Linear regression, cost function and gradient descent sum up the first two weeks of Professor Ng’s Machine Learning class on Coursera. Since I am not aspiring to be a mathematician, I am going to refer to them as algorithms. Each of these algorithms has a particular place when designing a machine learning solution. Linear regression, […]

ACE Exam Guide Stackdriver

Stackdriver is a set of tools for monitoring cloud resources. It appears, at the time of this writing, to be in a sort of transition from being an independent entity to becoming an integrated part of GCP. Perhaps because of this, Stackdriver requires a workspace. The workspace does not seem to be directly placed in […]

Machine Learning Fit the Model

I recently signed up for Machine Learning on Coursera (Andrew Ng, Stanford). In the first week of lectures, I already felt lost in the jargon. But nothing worth learning comes easy, so persistence, persistence, persistence. The first concept I realized that I didn’t understand involved fitting the model. When I searched the web, I found […]

ACE Exam Guide Using APIs

GCP has a GUI for finding and activating APIs called the Cloud API Library. There are three requirements and a sometimes condition for using a Cloud API. The first requirement, pretty obviously, is a Google account. The others seemed a bit more nuanced to me. The second requirement is a project from which to use […]

ACE Exam Guide About APIs

The API acronym comes up in so many different contexts that I needed to spend some time clarifying what it is. Essentially, “application programming interface” means exactly what the definition of the individual words are. “Application” is putting something into operation. “Programming” means the process of writing programs. “Interface” is the exchange of information between […]

ACE Exam Guide Project Permissions

It is not necessary to have an organization to create projects in GCP. Creating a project automatically generates certain permissions. GCP assigns the project owner role to the current user. It also generates GCP-managed service accounts required to run the resources. These accounts may have primitive or predefined roles and are authenticated with Google-managed keys. […]

ACE Exam Guide IAM vs Identity

Part of setting up a cloud solution environment involves managing users and assigning them roles. The GCP resources related to this are Cloud IAM and Cloud Identity. I realized that I didn’t have a good conceptual understanding of the difference between these. To gain this understanding, I needed to veer off into the world of […]

ACE Exam Guide Projects as Resources

Projects are part of the Google Platform Resource Hierarchy. They are at the bottom of the hierarchy. The top level consists of organizations. In between there can be up to ten levels of folders. At one point the Google Cloud documentation says “Folders are nodes….” (Creating and Managing Folders doc). This gave me pause as […]
