Getting Started With Robotic Process Automation

Aggregated on: 2022-09-29 22:14:01

Technologies such as artificial intelligence (AI), machine learning (ML), and natural language processing (NLP) have led the way to software robots that reduce the manual, time-consuming, and repetitive actions performed on digital platforms. The concept of automating tasks on digital platforms is called robotic process automation (RPA). RPA is a software robot that interacts with computer-centric processes and aims to introduce a digital workforce that performs repetitive tasks previously completed by humans. This Refcard introduces RPA technology, how it works, key components, and how to set up your environment.

Docker Desktop vs Rancher Desktop

Aggregated on: 2022-09-29 21:44:01

I’ve been regularly asked about comparisons between Docker Desktop and Rancher Desktop. As I have moved off of Rancher Desktop to work on other things at SUSE, I figure now is a good time to write up some of my thoughts. Note, there is an amazing team working on it now. They are incredibly talented and have made it better than I imagined. First, I need to say what respect I have for the people who have worked on Docker Desktop. Having worked on a cross-platform container desktop app, I’ve learned about so many nuances you have to deal with. They’ve done a lot of subtle work that I’ve learned to appreciate.

Using Rails Service Objects

Aggregated on: 2022-09-29 20:44:01

If you're developing web apps using Ruby on Rails, you probably already know that Rails is an MVC (Model-View-Controller) framework, which means that you have your Models responsible for data, Views responsible for templates, and Controllers responsible for request handling. But the bigger your app gets, the more features it has - the more business logic you will have. And here comes the question, where do you put your business logic? Obviously, it's not viewed that should handle it. Controllers or Models? That will make them fat and unreadable pretty soon. That's where Service Objects come to the rescue. In this article, we'll find out what are Rails Service Objects and how you can use them to make your app cleaner and keep it maintainable. Let's say you have a project for handling cab trips; we'll take a look at the particular controller action, which updates trip records. But it should not only update trips based on user input params (e.g., starting address, destination address, riders count, etc.), but it should also calculate some fields based on those params and save them to the database. So, we have a controller action like this:

High-Frequency Data Analysis: Working With Pivoting

Aggregated on: 2022-09-29 13:44:01

For high-frequency data in financial markets, each record typically holds the information of a stock at a specific timestamp. We often need to rearrange a column (or the calculation results involving multiple columns) into a matrix or table with the timestamps as row labels and security IDs as column labels. This operation (referred to as “pivoting”) can be achieved with the SQL pivot by keyword or the pivot function in DolphinDB. The result can be used in vectorized operations for optimal performance.  1. Calculating Pairwise Correlations of Stock Returns In pairs trading and hedging, we often need to calculate the pairwise correlations of multiple securities. Traditional databases are not able to perform such complex calculations. Using statistical software would require data migration between systems, which can be very time-consuming with a large amount of data. In DolphinDB, pairwise correlation can be calculated with the help of SQL pivot by clause.

Have you noticed how Google Maps predicts the estimated time of your arrival more and more precisely? How has Siri become better and better at understanding your requests? Have you ever bought Cryptocurrency or NFT?  Maybe you know someone who has. All these technologies are a small glimpse of the upcoming Web 3.0 - the newest iteration of the Web based on technologies such as blockchain and machine learning. The web is standing for "World Wide Web," which is the primary information retrieval mechanism on the internet. Terms the Web and the Internet can often be used interchangeably. In the history of the Internet, we had 2 phases of its evolution. The original Web 1.0. was the very first version of the Internet that lasted from 1991 till 2004. Web 2.0. is the current version of the Web that we all are familiar with. Web 3 or Web 3.0 is the next step in the evolution of the Internet. Let's take a deeper dive into the Web's history to get a better understanding of what's to come next and look at the opportunities and challenges that Web 3.0 creates.

Palindrome Program in Java

Aggregated on: 2022-09-28 20:29:01

A Java interview will most likely involve a scenario in which candidates will have to demonstrate their logical and programming skills, as well as their experience, as part of their evaluation of the candidate. Among the most common questions asked in interviews is "Can you write a palindrome program in Java?" This is also one of the most challenging questions to answer. Palindromes are nothing more than numbers or strings that remain unchanged when reversed, while a non-palindrome is the opposite of it. It is obvious that when letters are reversed, they form mirror images of one another. Originally from the Greek language, palindromes are numbers, words, or sets of characters that are spelt the same way forward and backwards. Among the many examples of palindromes are 686, 1401042, 95359, 7007, Malayalam, Radar, MAAM, Radar, Level, etc.  Upon reversing the letters, it is evident that they form mirror images of one another. With the remainder and division operators in Java, we can create a code that checks if a particular number is a palindrome or if it is not. In this article, we will learn how to check whether the input number is a palindrome or a number that is not a palindrome. Here we will discuss what is palindrome, what is palindrome number, as well as a sample palindrome program in Java. The first step to understanding Java's implementation of palindromes involves understanding the concept of palindromes.

Semantic Releases With CI/CD

Aggregated on: 2022-09-28 13:29:00

Software is constantly changing — the moment it is released, it begins to grow obsolete. Users need a constant stream of patches and want new features. At the same time, people hate when an update introduces a breaking change, especially when they were not warned about it. Forever it has been common practice to use version numbers and codenames to track releases. Many projects have incrementing sequences (MS-DOS 6.2, 6.21, 6.22); others use part of the release date (Ubuntu 18.04, 20.04, 22.04). A few have a more whimsical disposition: TeX, for example, uses a numbering scheme that asymptotically approaches π (the current version is 3.141592653), while Metafont does the same with e. Its current version sits at 2.71828182.

Java and Low Latency

Aggregated on: 2022-09-27 21:59:00

I have lost count of the number of times I have been told that Java is not a suitable language in which to develop applications where performance is a major consideration. My first response is usually to ask for clarification on what is actually meant by “performance” as two of the most common measures - throughput and latency, sometimes conflict with each other, and approaches to optimise for one may have a detrimental effect on the other.  Techniques exist for developing Java applications that match, or even exceed, the performance requirements of applications that have been built using languages more traditionally used for this purpose. However, even this may not be enough to get the best performance from a latency perspective. Java applications still have to rely on the Operating System to provide access to the underlying hardware. Typically latency-sensitive (often called “Real Time”) applications operate best when there is almost direct access to the underlying hardware, and the same applies to Java. In this article, we will introduce some approaches that can be taken when we want to have our applications utilise system resources most effectively.

Obtain Nearest Address to a Longitude-latitude Point

Aggregated on: 2022-09-27 21:29:00

In the mobile Internet era, people are increasingly using mobile apps for a variety of different purposes, such as buying products online, hailing taxis, and much more. When using such an app, a user usually needs to manually enter their address for package delivery or search for an appropriate pick-up and drop-off location when they hail a taxi, which can be inconvenient. To improve user experience, many apps nowadays allow users to select a point on the map and then use the selected point as the location, for example, for package delivery or getting on or off a taxi. Each location has a longitude-latitude coordinate that pinpoints its position precisely on the map. However, longitude-latitude coordinates are simply a string of numbers and provide little information to the average user. It would therefore be useful if there was a tool which an app can use to convert longitude-latitude coordinates into human-readable addresses.

For software teams, testing makes sense; applications should be screened for bugs. But why is testing important for your business, and how does it fit into DevOps? Testing is part of Continuous Delivery that assures quality at each stage of the delivery pipeline before moving on to the next stage. DevOps is an iterative cycle of building, testing, and releasing software in short iterations. A comprehensive testing environment helps each iteration of the DevOps loop strengthen the quality of the product. A weak testing phase can mean defects progress to release, and developers need to fix bugs while the product is live. Development teams fall on both sides of the testing spectrum.
