13 Best Linux Terminal Emulators and Bash Editors

Filed under

Linux Terminal Emulator is a truly useful and valuable tool for novice or super clients. Terminal Emulators assist you to utilize and collaborate with the shell of Linux systems. It provides you complete access to unleash the power of the system.

Furthermore, Linux Terminal Emulator is the most ideal approach to study commands of Linux without having a trained subsystem of Linux. There are no online terminals and bash editors accessible in the market to execute several commands and examine the results. If you don’t have a Linux system then you can explore the basics of system or test scripts and much more. Moreover, online terminal emulators and bash editors will assist you with excursion from this circumstance.

On the other hand, if we talk about bash editors then firstly we convey that there are two types of bash editors i.e. console-based editors and graphical user interface editors. Bash editors are used in order to write code or modify configuration files.

    The backdoor is a Windows kernel driver implementing advanced communication features that allows its operators to infect systems on highly secure networks and let them to communicate without detection, even when the systems can't connect to the Internet. These features are similar to the Regin malware discovered by Symantec in 2014, and which the company attributed to Western intelligence agencies.

Armbian 22.02 Is Here with Official Raspberry Pi Support, UEFI Support, and More

Filed under

Coming six months after Armbian 21.08, the Armbian 22.02 release is here to introduce initial support for Raspberry Pi devices. The Raspberry Pi 4 Model B board is currently supported with 64-bit builds using Raspberry Pi Foundation’s kernels 5.15 LTS and 5.16, as well as Debian’s flash-kernel tool.

While the Raspberry Pi support is still marked as WIP (Work in Progress), it would appear that the community is reporting success in running Armbian on various 64-bit Raspberry Pi boards, including the older Raspberry Pi 3 Model B and Raspberry Pi CM3 and CM4.

  • Old Portable TV Becomes Unique CRT Cyberdeck | Hackaday

    Remember the “suitcase” form-factor for PCs? In the time before latops, these luggable machines were just the thing for the on-the-go executive. OK, maybe not really — but the ability to have PC, monitor, and peripherals in a single package had real appeal, and a lot of that rationale is behind the cyberdeck phenomenon. So when we saw this retro portable TV turned into a cyberdeck, it really caught our eye.

    Ironically, the portable black-and-white TV that [Lucas Dul] chose as the basis for his cyberdeck hails from about the same period in time that luggable PCs were having their brief time in the sun. Scored from eBay, the Magnavox TV/radio combo had seen better days, and required a bit of surgery to repair what might have been drop damage. With the CRT restored and the video and audio paths located, the TV got a Raspberry Pi, a small touchpad, and a couple of concealed USB connectors. The Pi’s composite output drives the CRT, with about the results you’d expect. The keyboard appears to be just about the right size to serve as a cover, but [Lucas] said that’s a future project.

  • Linux Mint apparently runs better than Windows 11 on Surface devices [Ed: But why would you want to pay Microsoft for hardware (that it does not even produce) and for a Windows licence you neither want nor use?]

    No, it isn’t a joke, people took it upon themselves to try it and the results are actually better than what was initially expected from this experiment.

    Furthermore, users that have been using Surface devices since for graphics and work state that there is always something wrong with them.

    They are referring to either Windows OS-specific problems or questionable hardware configurations choices made by Microsoft.

    Regardless of the motivation that drove some to leave Windows 11 behind in favor of Linux, on Microsoft-designed laptops and tablets, the result is the same.

It’s Official! The Raspberry Pi Is Now 10!

Filed under

In any given field there are epoch-defining moments, those events after which nothing was quite the same as it had been before. It’s been a decade since the launch of the first Raspberry Pi single board computer. This was by no means the first inexpensive computer board, nor was it the first to support the GNU/Linux operating system, but it was among the first to promise a combination of those two. Coupled with support from a crop of British 8-bit alumni meant that from when it first gained publicity in early 2011 it garnered a huge buildup of interest.

We were first teased with a USB stick style prototype, which morphed into a much larger Raspberry Pi alpha board and finally into pre-production boards much closer to the model launched at the end of February ten years ago.

  • The Steam Deck’s Super Power: Super Sleep

    The Steam Deck undeniably has some great features, but if it were a superhero its superpower might not be what you expect. No, it’s not the powerful processor or advanced options and software, but seemingly the complete opposite of that: the Steam Deck’s real power is its super sleep. First, a superpower needs to be reliable and without any big caveats. The Deck’s sleep ability is just that: every time it works quickly and flawlessly. It is a quick power button press away or in the Steam button’s power menu. In the middle of a game without a pause button (hi, Elden Ring)? No problem. Running low on battery or just need a moment to move the Deck without accidentally hitting the buttons? Or want to resume in that spare minute to get in a quick gaming fix? The Deck delivers every time. You can also set the Deck to go to sleep after some idle time, confident you won’t lose your game progress or battery life.

  • Clang Static Analyzer and the Z3 constraint solver | Frederic Cambus

    Notes on using the Z3 constraint solver with the Clang Static Analyzer As far as static analyzers are concerned, one of the most important point to consider is filtering out false positives as much as possible, in order for the reports to be actionable. This is an area on which Coverity did an excellent job, and likely a major reason why they got so popular within the open source community, despite being a closed-source product. LLVM has the LLVM_ENABLE_Z3_SOLVER build option, which allows building LLVM against the Z3 constraint solver.

  • Least Common Denominator APIs

    Often, our instinct is to build for optionality. What if we change databases? What if we change clouds? We target the Least Common Denominator (LCD) interface to avoid vendor lock-in and make sure our software is portable – after all, Optimization is Fragile. LCD interfaces look like targeting the S3 API, a generic PubSub implementation, or vanilla ANSI SQL. LCD interfaces are good enough most of the time, but when we need to run a specialized workload, sometimes they don't perform how we'd like. We could solve our problem quickly by narrowing the API – coupling it to a specific cloud or managed service, but that destroys our optionality. Here, you should probably fight your instinct to stick with the pure implementation and weigh the trade-offs – how many developer-hours and pain can you save by narrowing the interface? Optimization and optionality are inherent trade-offs. There's a way to architecture services to be efficient and generic but also practical.

  • How To Write Comments In Python

    The way you think is reflected in programming in order to convey the individual steps that you took to solve an issue utilizing a computer. Commenting your code helps clarify your thinking process, which in turn makes it easier for you and other people to comprehend the purpose of your code in the future. Because of this, you will have an easier time locating bugs, fixing them, enhancing the code at a later time, and reusing it in other applications as well. The act of commenting is essential to the completion of any and all tasks, regardless of how little, medium, or fairly enormous they may be. It should be considered standard procedure for software engineers since it is an important component of your workflow. Without comments, things have the potential to get quite complicated very quickly. In this post, we will cover the many techniques of commenting that Python offers, as well as how it may be utilized to automatically produce documentation for your code via the use of the so-called module-level docstrings.
