Software Design – The Proxy Pattern

We continue a look at the structural patterns with a look at the proxy. This is much like the flyweight we reviewed in the last episode. However, it has a different focus. The flyweight can be used to implement a form of proxy but is a solution to a large number of instances where this is a different goal. The Proxy Pattern Defined As always, we will start with the “Gang of Four” intent to set the stage for our discussion. “Provide a surrogate or placeholder for another object to control access to it.” That, once again, provides a short and simple description of our pattern. The proxy saves us from having to instantiate an object before we start using it. The proxy... Read more

AWS Machine Learning Services

The AWS machine learning services are more examples of the newer offerings. Nevertheless, these are growing fast and can help you embrace cutting edge technology. Machine learning is a recent technology in general so the time you spend understanding these services may help you land that next job. Amazon SageMaker This service provides a method for building, training, and deploying machine learning models at any scale. This is a great way to try out machine learning. The time you spend here is good to use on your next resume update. You do need to put some data on S3 to analyze and then check out the use cases. There is a free tier for the first two months. Amazon Comprehend Quick... Read more

Mail Services – Free and Low Cost

This week we look at mailing and communication tools. These mail services have a wide range of features and focal points. That is just part of the reason why we also have a much longer list than typical. These applications are not quick to evaluate. Therefore, you should expect it to take weeks or maybe even months to truly find the best option for you. Common Features Most of the mail services we are looking at in this episode offer a way to build and maintain a list of recipients. There are also templates and automation or scheduling included with most and some simple reports. After that, the features go in different directions as some focus on the CRM side while... Read more

Software Design – The Flyweight Pattern

We continue a look at the structural patterns with a stop at the flyweight. This pattern is one I find ignored more often than it should be. In particular, the large number of data items we typically model in modern applications are often best handled through this pattern. The Flyweight Pattern Defined As always, we will start with the “Gang of Four” intent to set the stage for our discussion. “Use sharing to support large numbers of fine-grained objects efficiently.” Short and sweet. This intent is to model large collections in the best way based on data needed and memory considerations. A flyweight is an object-oriented approach to data modeling that is practically an index. We only keep up with the... Read more

Maintaining Focus At The Year End

The Holidays bring their own set of challenges to our business lives. One of the most significant is the impact to maintaining focus. We have days off, co-workers on vacation, customers at parties, and vendors taking time off (or a mix of those situations) to contend with. We also tend to have tasks that need to get done before year end. All of this can make the final weeks of our year a stressful period. The Way Forward Every time I run into an obstacle like this I find it best to step back and simplify things. We usually need to start this season by acknowledging our limits. It is almost impossible for us to get everything done that we want... Read more

AWS Media Services

The AWS media services are among their more recent offerings. Nevertheless, these are applications you may find critical to your cloud strategy. These may not be very familiar to you if media processing is not your thing. On the other hand, they are what you hope for if it is your focus. Amazon Elastic Transcoder: Easy-to-use Scalable Media Transcoding The first service we look at is the transcoder. It has a simple function of translating video media from one format to another. Fortunately, it has a free tier of twenty minutes of transcoding each month. Thus, you can “play around” with it and avoid fees. Once you get beyond the free threshold, it is priced based on the resolution and length... Read more
