What if you could have a tiny text editor with different modes to emulate your choice of Emacs, Vi, Pico, NEdit, and even WordStar? Amazingly, such an editor already exists, and it’s called e3. It has no library dependencies, and its binary is less than 20KB. Installing On Linux or BSD, you can install e3 from your distribution’s software repository or ports tree. read more

Big Red: This is not some gimmick so that you buy support from us In the wake of Red Hat's decision to end support for CentOS Linux comes a raft of alternatives to fill the void, including Project Lenix - an offshoot of Cloud Linux - and Oracle's free Linux, which Big Red is heavily promoting.…

Being able to build and tear down a public cloud environment is very useful, but most of us don’t have easy access to a public cloud. The next best thing would be to have a lab on your local machine, but even running on a local machine brings performance, flexibility, and other challenges. Most of the time, the additional workloads on our local machines interfere with doing our daily job, and they certainly prevent having a readily available environment to play and experiment with new software. read more

I’ve spent a considerable amount of time in NetBeans, a Java IDE (integrated development environment) maintained by the Apache Foundation. I find it’s got a good mix of automated abstraction and manual configuration that helps me keep my Java projects organized and optimized. Not all IDEs give much thought to text files, but XML is frequently used in Java projects, so XML support in NetBeans is an important feature. read more

A multi-tier application is an application distributed among more than one layer. It logically separates the operational layers. The number of layers varies with business and application requirements. In this article, we will see an application divided into 2 layers, backend and frontend layer.

The Brackets text editor is an editor geared primarily at web developers. Appropriately, its Edit menu is full of functions especially useful to users of web programming languages, with a focus on the classic combination of HTML, CSS, and Javascript. However, it supports many languages and formats relevant to the internet, including XML, Markdown, YAML and JSON, PHP, Lua, Java, and Python, as well as some common general languages like C, C++, and even the output of diff commands. read more

The GNU ed command is a line editor. It’s considered the standard Unix text editor because it was the very first text editor for Unix, and so it was (and generally still is) available on any POSIX system. In some ways, it’s easy to tell that it was the first because, in many ways, it’s extremely rudimentary. Unlike most other text editors, it doesn’t open in a window or screen of its own, and in fact, by default, it doesn’t even prompt the user for input. On the other hand, its near lack of any interface can also be a strength. read more

Throughout much of 2020, virtual meetings have been a major part of our lives. This is new for many of us—while we may have participated in webinars or other virtual meetings on occasion, we have never relied on our webcams for doing our day-to-day work. read more

AWS S3 Storage Lens gives visibility into object storage usage, activity trends. It gives recommendations to improve cost-efficiency, also it applies data protection best practices. It is the first analytics service that provides a  single view of object storage usage and activity across hundreds and thousands of accounts in an organization.

There’s always room in my Activities menu for a utilitarian text editor. Of course, the exact meaning of "utilitarian" is different for each user, but for me, it means a text editor with all the features I need and not much else. So far, FeatherPad has proven in many ways to fit these requirements. read more
