Linux supports a wide range of software, including web browsers, office suites, multimedia players, and development tools. Many popular applications, such as Chrome, Firefox, and LibreOffice, have Linux versions available. One of the most common Linux careers is Linux system administration, which involves managing an organization’s Linux setup.⁴ Linux administrator jobs entail installing, updating, backing up, and configuring Linux systems. Job duties may also include writing documentation and providing technical support. Sometimes, being a Linux system administrator is part of another role in the information technology department of an organization. It’s possible to start with entry-level Linux jobs and eventually run massive networks using Linux while managing other Linux system administrators.

  • With the C Programming with Linux Specialization from Dartmouth College, you’ll gain foundational knowledge of computer programming and Linux, compile C code with Linux, and manage processes.
  • For major companies, the cost of building something on the scale of DBRX makes perfect sense, he says.
  • PDFrankenstein is a GUI PDF annotation tool based on Inkscape, a popular vector graphics editor.
  • “Any system that had affected packages installed should be treated as a potential security incident and investigated to determine if the backdoor was used,” notes Bar Kaduri, Research Team Leader at Orca Security.

To help new Linux users, the Red Hat Training and Certification team now offers the RH104 course Getting Started with Linux Fundamentals, a course designed for the absolute beginner. The command line in Linux is a powerful tool for performing a wide range of tasks, from file management to system administration. You can use commands such as cd, ls, mkdir, and rm to navigate and manipulate files and directories.

What is Linux, and why is it important to learn?‎

The PDF annotation feature can be found in many PDF editors but there exist specialized programs that don’t usually offer editing functionality. Security researchers have credited Freund with going the extra mile to hunt down the issue, ultimately revealing the backdoor in the software. Jia Tan, whose handle was JiaT75, had begun contributing to XZ Utils at least two years ago, according to Sam James, a contributor to Linux projects, in a GitHub post. Jia Tan “gained commit access, and then release manager rights, about 1.5 years ago,” James wrote. [Updated] XZ Utils has been found compromised starting with version 5.6.0. Small, personal innovations are an important step toward inventing a truly new solution.

  • Linux offers a wide range of automation tools, such as cron and systemd, for scheduling and running tasks automatically.
  • But if you are not in the mood to spend a few bucks, I have compiled this list of free Linux training courses.
  • Linux Foundation is the official organization behind the Linux project, and they have training and certification courses on cutting-edge Linux technologies.
  • Ultimately, “the malicious code found in the latest versions of the xz libraries show just how critical it is to have a vigilant and veteran Linux security team monitoring software supply chain channels,” he said.
  • While the full extent of its capabilities is still being investigated, we known it can be triggered by remote unprivileged systems connecting to public SSH ports.
  • The app offers customizable pen, highlighter, and eraser tools and is compatible with the most popular drawing tablets and pressure-sensitive stylus.

Its distinctive feature is compatibility with a large number of popular formats, including PDF, DjVu, EPUB, JPEG, PNG, GIF, CBR, CBZ, and more. When it comes to PDF annotation, the ONLYOFFICE editor lets you highlight text with different colours, underline what’s important and strikethrough unnecessary parts. You can also leave your comments and reply to comments left by other users. The built-in PDF tool can also be used as a file converter allowing you to save your PDFs as DOCX, ODT, TXT, FB2, RTF, and EPUB documents as well as PNG and JPG images. In addition to documents, spreadsheets, presentations, and fillable forms, the ONLYOFFICE suite can open PDF files for viewing.
