  • How to use LUKS with a detached header

    Linux Unified Key Setup (LUKS) is the de-facto standard block device encryption format used on Linux-based systems. We already discussed some of the features provided by it in a previous tutorial about using a file as a LUKS device key. When using LUKS, encryption metadata is stored on the header which is created at the beginning of the encrypted device (a copy of the header is created at end of the device for redundancy, when using LUKS2).If desired, it is possible to specify that the header should be detached from the device: in this tutorial we see how.

  • Install Node.js 17 & NPM on Debian 11 Bullseye - LinuxCapable

    Node.js is an open-source, cross-platform, back-end JavaScript runtime environment built on Chrome’s V8 engine to build fast and scalable network applications and back-end APIs. Node.js uses an event-driven, non-blocking IO module that makes it very lightweight and practical. It is a fantastic choice for data-intensive real-time applications across distributed devices.

    NPM is a package manager for the JavaScript programming language maintained by NPM, Inc. NPM is the default package manager for the JavaScript runtime environment Node.js and is arguably the most available repository for Node.JS packages.

  • Steinar H. Gunderson - Speeding up Samba AD

    One Weird Trick(TM) for speeding up a slow Samba Active Directory domain controller is seemingly to leave and rejoin the domain. (If you don't have another domain controller, you'll need to join one in temporarily.) Seemingly, not only can you switch to LMDB (which has two fsyncs instead of eight on commit—which matters a lot, especially on non-SSDs, as the Kerberos authentication path has a blocking write to update account statistics), but you also get to regenerate the database, giving you the advantage of any new indexes since last upgrade.

  • How to Change File Extensions on Linux

    File extensions help both operating systems and users distinguish between different file formats and understand the contents stored inside them. When you see a file with the ".txt" extension, you instantly know it contains text data. Similarly, ".exe" file is a Windows executable and ".sh" files are Linux shell scripts. But what if you want to change these extensions for some reason? Perhaps you need to rename a text file to a Bash script. Simply writing the code in a text file won't do the job. On Linux, changing file extensions is much easier than you might think.
