What Is Web Data Harvesting

Aggregated on: 2021-10-24 11:40:32

Web data harvesting is the method of collecting organized web data in an automated way. It's likewise called web data scraping or web data extraction. The term data harvesting, or web data scraping, has reliably been a concern for site service providers and information publishers. As a modest and simple approach to collecting online data, the strategy is frequently utilized without permission to steal website data like text, photos, email addresses, and contact lists. How To Use Web Data Harvesting Data harvesting is the process to extract important information out of target websites and putting them into your database in an organized format. Data harvesting, hence, doesn't include algorithms, AI, nor measurements. Instead, it depends on computer programming like Python, R, Java, to work. Plus, data harvesting is more about being precise.

How To Copy Files From One Directory to Another in Java: Example

Aggregated on: 2021-10-23 23:10:19

Hello folks. I have been programming in Java for a long time, and you won't believe it, but there was no file copy method in the Java API until Java 7. Our options were either to: write it ourselves using a FileInputStream, a FileOutputStream, and a buffer to copy bytes from one to the other; or, better yet, use the FileChannel.transferTo() method or the Apache Commons FileUtils, which was a lifesaver in those days and still is today. JDK has evolved now, and you have a decent API to copy files from one directory to another. In this article, I'll show you both the pre-Java code for copying files from one directory to another as well post Java 7 code, which makes this task a lot easier.

How to Change Certificates At Runtime Without Downtime

Aggregated on: 2021-10-23 18:25:19

Certificates Are Always a Pain in the Production Environment! Security is one the most important part of any application these days especially the fact that most of the applications are running on a public cloud provider puts the security part on a higher priority. One of the ways applications are used to keep communications secure is through the certificate. The certificate is one of the concepts that is not as easy as other parts of software development. First, you should understand how a certificate plays in the security part to figure out how to incorporate it into your application security. Moreover, you need to know how to generate/issue a new certificate for your application. Unfortunately, certificate generation is not a one-time job and it has an expiration date. So, it means a new certificate should be replaced with the current certificate before the expiration date comes. In most cases, the certificate information is used in configurations of a deployed application on production. Therefore, you need to generate a new certificate and redeploy your application on production. This creates difficulties for software teams to see how they can handle this issue and justify the downtime in production if there is no rolling update mechanism. Lack of knowledge and documentation in projects often makes this operation highly error prune. Therefore, there is a high chance that even after a new certificate something fails on production unexpectedly because of misconfiguration. In this article, we are going to see how we can solve this issue without having downtime on production while using a single server and without any changes on the application level.

An Introduction to Incident Response Roles

Aggregated on: 2021-10-23 18:25:19

In the world of reliability engineering, folks talk frequently about “incident response teams.” But they rarely explain what, exactly, an incident response team looks like, how it’s structured, or which roles organizations should define for incident response. That’s a problem because your incident response team is only as effective as the roles that go into it. Without the right structure and responsibilities, you risk leaving gaps in your incident response plan that could undercut your team’s ability to respond quickly and efficiently to all aspects of an incident.

Increasing code quality with Hyperlambda

Aggregated on: 2021-10-23 10:25:19

Fundamentally Hyperlambda is really just a Turing complete markup language, with some added capabilities resembling features from XSLT and XPath. You could argue Hyperlambda is the programming equivalent of YAML. On the index of "programming level abstractions" if we argue that CISC x86 assembly code is at level 1 (the bottom level) and C# and Java is at level 5, while Python and PHP are at level 10 - Hyperlambda is at level 100+ somewhere. Of course, the point being, that 95% of the times you need a low level programming construct, Hyperlambda implicitly creates your C# objects and ties these together 100% correctly out of the box. This reduces the cognitive complexity of your resulting app's code by orders of magnitudes. To illustrate this difference, please have a look at the following code snippet taken from Microsoft's official documentation for how to correctly create an HTTP request from C#.

Improving Backend Performance, Part 3/3: Fast Analytics

Aggregated on: 2021-10-22 20:10:19

Analytics involves the computation of data to find patterns. From simple calculations - such as the sum of values or its average to statistics calculated with machine learning algorithms, analytics frequently deals with big amounts of data that need to be processed as fast as possible. We saw in the previous part of this series of articles, how indexes help to improve the speed of database operations. And in all honesty, the problem in the laboratory application shown in this article can be solved by merely adding an index. However, in real-world applications with many tables that have a lot of columns, dealing with indexes can become difficult. In this article, I explore one interesting technology that helps with analytic SQL queries: ColumnStore using Spring Boot and Vaadin Flow.

How to Build the Process and Culture Behind Using Feature Flags at Scale

Aggregated on: 2021-10-22 19:25:19

Feature flags are a great way to release features quickly with very low risk — they allow software teams to make changes without re-deploying code. They have the power to make an organization’s DevOps practices more efficient, enabling testing in production. They can help developers, operations, QA, product, customer success, sales, and marketing teams deliver higher-quality features, faster. But like many powerful tools, feature flags need to be used with care. When an organization adopts feature flags, it needs to simultaneously adopt a set of best practices for using them effectively and safely. This article goes beyond a technical “how-to” guide for implementing feature flags, and into the realm of process and culture. Sure, you can start using them today as an individual or a small team, but to truly realize the benefits of feature flags, the entire organization needs to embrace them — and without the necessary process and cultural shifts, you can accumulate a very large load of technical debt very quickly. At best, you’ll end up with bloated code, and at worst, the bloated code can lead to catastrophic events.

Benchmarking AWS Graviton2 and gp3 Support for Apache Kafka

Aggregated on: 2021-10-22 18:25:19

With the release of AWS’s Graviton2 (ARM) instances and gp3 disks, I immediately wanted to explore the potential opportunity for anyone using Apache Kafka. My team and I embarked on a journey to understand the changes required for Kafka users to be able to provision AWS Graviton2 instances paired with gp3 disks. Previously we’d only used Java 11 (OpenJDK) to run the Kafka service on x86 instances. As part of this change, we also shifted our internal environment to use Amazon Corretto. Amazon Corretto is used internally by AWS; it has built-in performance enhancements, security fixes, and is compatible with Java SE standards. Furthermore, Amazon Corretto reportedly has a performance benefit over OpenJDK distributions when operating in ARM architecture especially for network-intensive applications, of which Kafka is one.

GPU for DL: Benefits and Drawbacks of On-Premises vs. Cloud

Aggregated on: 2021-10-22 18:25:19

As technology advances and more organizations are implementing machine learning operations (MLOps), people are looking for ways to speed up processes. This is especially true for organizations working with deep learning (DL) processes which can be incredibly long to run. You can speed up this process by using graphical processing units (GPUs) on-premises or in the cloud. GPUs are microprocessors that are specially designed to perform specific tasks. These units enable parallel processing of tasks and can be optimized to increase performance in artificial intelligence and deep learning processes.

5 Reasons Why I Dread Writing Embedded GUIs

Aggregated on: 2021-10-22 17:55:19

A consequence of the massive adoption of Internet of Things technologies across all industries is an increasing need for embedded development skills. Yet, embedded development has historically been a pretty complex domain, and not something that one can add to their skillset overnight. Luckily, over the last decade, silicon vendors have put a lot of effort into simplifying embedded development, especially for people with little to no experience in the domain. Communities such as Arduino and PlatformIO have also immensely contributed to providing easy-to-use tools and high-level libraries that can hide most of the scary details—yes, assembly, I'm looking at you!—of embedded programming while still allowing for professional applications to be written.

What Is Ant, Really?

Aggregated on: 2021-10-22 17:55:19

Ant is a bit of a mystery bag. Its behavior is often obscure until you come to look at its code. Then you find that it consists of a number of fairly simple facilities that are often explained from a bottom-up detailed and technical viewpoint and not from a top-down architectural perspective. This article aims to provide the missing top-down view. It is targeted at an audience of software engineers. Armed with this article, and some solid opinions on when and when not to use this tool, you should be able to find your way in the anthill. Ant History, Legacy, and Impact If you have never heard of Ant, don't worry. Ant is yet ANother Tool in the realm of building software. It was the first attempt at a build tool for Java. When it was conceived, XML was all the rage, and C was the way to express software that Java mimicked. Consequently, Ant was influenced by the thinking of C's make tool. Combining these two trends, Ant is a curious hybrid that does not have make's terseness or stringent reproducibility but does have XMLs verbose syntax. Talk about the best of both worlds.

URL Shortener Complete Tutorial

Aggregated on: 2021-10-22 04:10:18

Introduction A URL shortener is a service that is used to create short links from very long URLs. Usually, short links have the size of one-third or even one-fourth of the original URL, which makes them easier to type, present, or tweet. Clicking on a short link user will be automatically redirected to the original URL. There are many URL shortening services available online, such as tiny.cc, bitly.com, and cutt.ly. Implementing a URL shortening service is not a complex task, and it is often part of system design interviews. In this post, I will try to explain the process of implementing the service.

How to Reduce Onboarding Costs by Using a Code Repository

Aggregated on: 2021-10-22 02:40:18

Onboarding new developers into a project is a time-demanding and costly process, isn’t it? Just finding a proper specialist isn’t sufficient. We all know that every software development company has its own practices and uses its own tools. And those tools might even be in-house developed. Therefore, it doesn't matter how skilled and experienced your new team member is, they will need to learn a lot. Sometimes, it takes pretty much time for them to learn all about the project they start working on (to start coding new features, for example), about the company’s corporate culture, and the commonly accepted practices and processes. Needless to mention the extensive documentation, and similar.

For instance, while there is a solitary metric that addresses a Gauge, a Timer estimates both the number of coordinated occasions and the absolute season of all occasions planned.

Oracle Partition Pruning

Aggregated on: 2021-10-21 19:55:18

Oracle database optimizer analyzes your SQL statement, if there is a partitioned table and "appropriate" where condition, it decides which partitions will be ignored and which partitions will be accessed and read. This is called partition pruning. It is an essential performance feature for data warehouses. As you can guess, when you prune some of the partitions, the data you need to read from disks is reduced considerably, which leads to shorter processing times.

Data Fabric: What Is It and Why Do You Need It?

Aggregated on: 2021-10-21 19:55:18

Insight-driven businesses have the edge over others; they grow at an average of more than 30% annually. Noting this pattern, modern enterprises are trying to become data-driven organizations and get more business value out of their data. But the rise of the cloud, the emergence of the Internet of Things (IoT), and other factors mean that data is not limited to on-premises environments. In addition, there are voluminous amounts of data, many data types, and multiple storage locations. As a consequence, managing data is getting more difficult than ever. One of the ways organizations are addressing these data management challenges is by implementing a data fabric. Using a data fabric is a viable strategy to help companies overcome the barriers that previously made it hard to access data and process it in a distributed data environment. It empowers organizations to manage mounting amounts of data with more efficiency. Data fabric is one of the more recent additions to the lexicon of data analytics.

Motivation This article is an overview of the path we followed to migrate Spark Workloads to Kubernetes and to avoid EMR dependency. EMR was an important support tool at Empathy.co to orchestrate Spark workloads, but once the workloads became more complex, the use of EMR also became more complicated. So, back in December 2020, the Step Function flow to orchestrate the different EMR clusters was like this: In January 2021, an initial Spark on Kubernetes RFC was proposed by the Platform Engineering team. The aim was to have a better solution with less possible friction between teams, especially the Data and Ether teams, the main users of the Spark workloads.

Best Mapping API: Mapbox, Google Maps, or OpenStreetMap?

Aggregated on: 2021-10-21 18:10:18

Google Maps has long been the go-to maps and location data API provider – and it makes sense. Google's solutions are robust and reliable, with a wealth of mapping data available for over 200 countries. With 1 billion monthly active users (and over 5 million active sites and apps using it), you would think that Google Maps is uncontestable. However, ever since Google hiked its Maps API prices back in 2018, developers have been turning to more affordable options. Is it possible to find a budget-friendly alternative to Google Maps without compromising on functionality? Let's find out. The Google Maps API Dilemma Google Maps APIs have left a bitter taste in the mouths of many developers. A price hike is understandable – but raising prices this drastically was a controversial move. Before the 2018 pricing change, if a website or app exceeded 25,000 dynamic map views per day, they would need to pay $0.50 for every 1,000 additional requests. That price rose to $5 per 1,000 requests: an increase of 1,400%.
