rga: Search Text In PDF, Ebooks, Office Documents, Archives And More (ripgrep Wrapper)

rga (or ripgrep-all) is a command line tool to recursively search all files in a directory for a regex pattern, that runs on Linux, macOS and Windows. It's a wrapper for ripgrep, the line-oriented recursive search program, on top of which it enables search in a multitude of file types like PDF, DOCX, ODT, EPUB, SQLite databases, movies subtitles embedded in MKV or MP4 files, archives like ZIP or GZ, and more. rga is great when you want to search for some text from a file available in a folder with many documents of various file types, even if some of them are available in archives.

Security: Updates, Containers, Compilers and More

• Security updates for Wednesday

• Containers pose security risks, but mitigation isn't tough: Lees

  Recent concerns over the security offered by containers are not unjustified, the chief technologist for Germany-based SUSE in the Asia-Pacific says, adding however that there are a lot of operational things that could be done to mitigate the risk. Peter Lees told iTWire in response to queries that the whole point of containers was to be able to get new functionality out quickly. "And in modern development that often means gluing together micro-services from many different sources, which in turn could mean that the ultimate source of those functions may not have been vetted," he said. Container security was in the limelight in April when the credentials of some 190,000 account holders at Docker Hub, the official repository for Docker container images, were exposed due to "a brief moment of unauthorised access".

• Ubuntu 19.10 To Harden Its Compiler With Stack Clash Protection & Intel CET

  In addition to discontinuing i386 support, Canonical announced another change being worked on for Ubuntu 19.10 is compiler hardening. In the name of increased security, their GCC 9 compiler for Ubuntu 19.10 will have some additional tunables enabled: -fstack-clash-protection and -fcf-protection. The stack clash protection is designed to fend off stack clash attacks by checking pages at allocation-time that instead would result in ideally just a segmentation fault.

  Security researchers over at Netflix uncovered some troubling security vulnerabilities inside the Linux (and FreeBSD) TCP subsystem, the worst of which is being called SACK. It can permit remote attackers to induce a kernel panic from within your Linux operating system. Patches are available for affected Linux distributions.

9 Best Free Linux Biology Tools

Biology is a natural science concerned with the study of living things, ranging from microscopic organisms up to the largest known animal, the blue whale. It is divided into many specialized fields including evolution, ecology, zoology, botany, genetics, microbiology and molecular biology. This science examines function, structure, origin, growth, evolution, distribution and taxonomy. Biology is extremely relevant to our daily lives, as it helps us to understand how living things work, including the human body. Furthermore, the study of biology is crucial in the development of new food products, to protect the environmental quality of our world, and improving human health e.g. through the discovery of new medical treatments and tests for diseases. Modern biology is founded on four main components: cell theory, evolution, gene theory, and homeostasis. Schools recognize the importance of biology to society, regarding it as one of the three most important branches of sciences, alongside physics and chemistry. We covered the best open source Linux software available for these disciplines in the following articles: Physics, Chemistry. Biology is at the cutting edge of scientific research and development. In the past 40 years, biology has advanced enormously revealing a wealth of information about the millions of different organisms inhabiting our planet, including, of course, ourselves. Biology continues to grab the headlines with much excitement being generated in the fields of synthetic biology (combining science and engineering) and genomics (the study of the genomes of organisms). A good range of open source biology software is available for Linux. This article focuses on selecting our favorite tools which are extremely useful for biologists. We hope this feature offers a useful resource for biologists and students alike. With the diverse range of software, there should be something of interest here for all budding biologists.
