During my college years, as a software engineering student, Java was the new kid on the block. Fortunately, I had a few visionary professors eager to tag C++ as something of the past and move forward to the wonderful world of “code once, deploy anywhere”. Most of the assignments were in Java, but we also tried other technologies such as C, C++, Cobol, OCAML… and JavaScript. As soon as I started to work with JavaScript, I got the immediate feeling that it was designed with an hack & slash approach to get something done and should not outlive more than a couple of prototypes. No one back then was willing to bet the farm on JavaScript, but we couldn’t be more wrong. Twenty years later, our industry allowed JavaScript to move to the back-end and now it’s everywhere. Why Ruby on Rails in the first place? The years following my graduation were, as foreseen by the university professors, spent coding in Java. I loved how Sun designed the language and Java VM, but I always questioned their over-complicated way of designing the Standard Development Kit (SDK). It seemed like they were eager to use every pattern in the famous book written by the Gang of Four, and the first contact with J2EE gave me the impression that Martin Fowler offered Sun the draft to his yet to be published book Enterprise Design Patterns, and they made a TODO list out of it. The Java ecosystem was so over-engineered that it became a common practice to factor two weeks in a project plan just to bootstrap a slightly complex product....
A new study published in PLOS One has found a relationship between a person’s body shape and their family income. The findings provide more evidence for the “beauty premium” — a phenomenon in which people who are physically attractive tend to earn more than their less attractive counterparts. Researchers have consistently found evidence for the beauty premium. But Suyong Song, an associate professor at The University of Iowa, and his colleagues observed that the measurements used to gauge physical appearance suffered some important limitations. “I have been curious of whether or not there is physical attractiveness premium in labor market outcomes. One of the challenges is how researchers overcome reporting errors in body measures such as height or weight, as most previous studies often defined physical appearance from subjective opinions based on surveys,” Song explained. “The other challenge is how to define body shapes from these body measures, as these measures are too simple to provide a complete description of body shapes. In this study, collaborated with one of my coauthors (Stephen Baek at University of Virginia), we use novel data which contains three-dimensional whole-body scans. Using a state-of-the art machine learning technique, called graphical autoencoder, we addressed these concerns.” The researchers used the deep machine learning methods to identify important physical features in whole-body scans of 2,383 individuals from North America. The data came from the Civilian American and European Surface Anthropometry Resource (CAESAR) project, a study conducted primarily by the U.S. Air Force from 1998 to 2000. The dataset included detailed demographic information, tape measure and caliper body measurements, and digital three-dimensional whole-body scans of participants. “The...
Cloud access security brokers (CASBs) and identity and access management (IAM) tools are both security solutions designed to help protect enterprise assets stored in the cloud from threats. But when it comes to CASB vs IAM, how exactly do these two solutions differ? And how do they work together? To begin with, CASBs monitor cloud-based applications, data, and services. Conversely, IAM manages user access to cloud resources based on identity information — such as usernames and passwords, or digital keys and certificates. CASB vs IAM: Do They Work Together? Each tool serves to improve visibility across hybrid IT infrastructure while enhancing collaboration between security teams. CASBs monitor activity across a variety of cloud-based services, which means they have a bird’s eye view of how people are accessing applications from different locations. CASBs alert IAM tools when new devices appear, and IAM checks with CASB to see what credentials were used. CASBs alert IAM tools when new devices appear on the network, and IAM checks with the CASB to see what credentials were used to gain access. Once the CASB tells IAM about new devices connecting with corporate assets, IAM can check user access levels against permissions in place, blocking or removing privileges for certain accounts while leaving others untouched. These two systems to work together to provide robust protection against common threats, like phishing schemes or malware infections, through vulnerability scanning. How Can You Integrate IAM With CASB? Integration techniques differ depending on your specific needs and priorities, but some simple ways to increase efficiencies can be achieved without too much additional effort. By providing IAM admins with a...
Ruby on Rails is an established, battle-tested technology that served as an excellent framework for software developers. But what’s the secret behind the success of Rails? One good reason is that ever since it appeared on the tech scene, it’s been part of projects launched by companies that have become some of the fastest-growing and largest startups we’ve ever seen. Read on to find out why startups choose Rails and discover the most spectacular success stories of companies based on RoR. Why do startups pick Ruby on Rails? There are many reasons why Ruby on Rails has become such a critical technology for startups that want to transform their business ideas into applications and saleable products quickly. But these 3 features make RoR incredibly successful among startups: Efficiency – Rails includes many tools, plugins, and modules that allow developers to save plenty of time and avoid writing boilerplate code. Rails teams build applications 30–40% faster than teams with a different technology stack. Scalability – it’s easy to scale up applications built with RoR to match the constantly evolving business need or unpredictable events. Moreover, if you’re creating a product for a large user base, Rails helps to ensure that once it kicks off, it can cope with all the visitors. Cost-effectiveness – Rails is an open-source framework distributed under the MIT license, so you don’t need to spend any money on the framework. RoR is surrounded by an ecosystem of fantastic free tools that speed up the development process and let your team focus on what matters most – the value your product brings to end-users. Now that you...
Today, we’re announcing .NET Core 3.0 Preview 9. Just like with Preview 8, we’ve focused on polishing .NET Core 3.0 for a final release and aren’t adding new features. If these final builds seem less exciting than earlier previews, that’s by design. Download .NET Core 3.0 Preview 9 right now on Windows, macOS, and Linux. ASP.NET Core, EF Core and Visual Studio are also releasing updates today. Details: .NET Core 3.0 is launching at .NET Conf Tune in for .NET Conf, September 23-25th. We will launch .NET Core 3.0 during .NET Conf. Yes, that means that Preview 9 is the last preview, and .NET Core 3.0 will be released in its final version later this month. We have a lot of great speakers and content prepared for .NET Conf this year. It’s one of the big .NET developer events each year, and you cannot beat the price. It’s free and streaming online. Visual Studio Support .NET Core 3.0 is supported with Visual Studio 2019 16.3 Preview 3 and Visual Studio for Mac 8.3, which were also released today. Please upgrade to it for the best (and supported) experience with .NET Core 3.0 Preview 9. See Visual Studio 2019 16.3 release notes for more information. We know that some folks have been successful using .NET Core 3.0 builds with Visual Studio 2019 16.2 and wonder why 16.3 is required. The short answer is that we only test .NET Core 3.0 with Visual Studio 2019 16.3 and have made many improvements and key fixes that are only in 16.3. The same model applies to Visual Studio for Mac 8.3. The C#...
