  • HOWTO: install MongoDB on Slackware

    Today I am going to show you how to install MongoDB, create a database admin account and enforce basic security.

    Why MongoDB when Slackware already has MariaDB? Well, the two are not comparable. MariaDB is a SQL database server, whereas MongoDB is a “NoSQL” database server, aka “Not only SQL“, and its queries – just like its object storage format – are in JSON. The two types of databases have entirely different usage targets.

    MongoDB is a ‘general-purpose, document-based database server‘. It has use-cases where it is more powerful than the traditional row/column model of a relational database management system. NoSQL databases, in particular MongoDB, are preferred over RDBMS in Cloud services, Big Data environments and for high-volume web based data processing services. These are typically environments where flexibility is required to handle big amounts of unstructured data and constantly varying schemas. A distributed cluster of MongoDB servers excels at “map-reduce“, the framework invented by Google for condensing large volumes of data into useful aggregated results – the very paradigm that catapulted Google Search into the number one position of search engines shortly after the turn of the millennium.

  • MariaDB/MySQL Auto-Сlustering with Load Balancing and Replication

    These days high availability and database clustering are very important for highly loaded production applications. If your server is down for a fraction of time, you are losing customers and money. Therefore making a database environment highly available has typically one of the highest priorities. Set up a highly available cluster is not easier for any developers and system administrators.

  • How To Fix The GIMP Eraser Not Working

  • Hunting Excel date twins

    Certain versions of Microsoft Excel for Mac counted days from 1 January 1904, while other Excel versions numbered their days from 1 January 1900. Microsoft calls these "the 1904 date system" and "the 1900 date system", and says there are problems you may encounter when you use workbooks that use different date systems.

    I wrote about one of those problems in a 2017 post for The Linux Rain blog. If you compile a spreadsheet using a mix of "1900" and "1904" dates, you might have the same record represented twice, with dates exactly 4 years and 1 day apart (1462 days). These pseudo-duplicates are "Excel date twins".

    The first twins I found (by accident) were in the Atlas of Living Australia (ALA) and had been imported from the Tasmanian Natural Values Atlas (TNVA). From the ALA they went to the Global Biodiversity Information Facility (GBIF). Both records say that I observed the peripatus species Ooperipatellus cryptus at a certain spot in Tasmania. One record says I did it on 3 February 1976, the other on 2 February 1972. The second date is an Excel date twin and impossible: I first came to Australia in January 1973.

  • How to Install or Enable Cockpit on AlmaLinux 8 - Linux Shout

    The Cockpit on AlmaLinux is a server management platform that allows administrators to easily manage and control their GUI or CLI Linux server systems remotely using a browser. Among other things, admins can take a look at the systemd journal, check the load or start and stop services. It has a responsive design thus we can also use it conveniently on tablet s and smartphones. We can monitor our remote server performance using just a browser without actually having physical access to it. Furthermore, we can also access the command shell with root access to issue commands and install various packages over the server remotely. Since AlmaLinux 8 is based on RHEL just like CentOS 8, this means by default out of the box, the Cockpit is already installed on your system. Just we need to enable it.
