Deb10x Edition - Released

devfd012 Edition - Released
Integral to the functioning of C-oriented IO streams is the notion of file-descriptors. In particular, three standard file-descriptors are found across implementations and are regularly instantiated and referenced by users, processes and the kernel alike. (Input | Output | Error Handling) are the three requisite file-descriptors you should be comfortable with when navigating Linux, Unix and other modern systems.

ngx-mods Edition - Released
NginX, unsurprisingly like its contemporaries, is modular. Standard-issue is replete with useful, common-denominator modular functionality of varying degrees. However, peer a bit deeper and realize a world of interesting extended functionality, which renders NginX even more apt in its stance, disposition, capabilities, and prowess. NginX is highly-programmable, which lends relief to the initiated Web Administrator. Let's have a glance @ some of the salient modules of interest in this release.

Once employed, there is NO excluding this tool from your kit. More-or-less invaluable. 'rsync' is rated.
Synchronize Content with 'rsync'.

Sockets Edition - Released
Core to IP communications is the Socket. Sockets wed Clients and Servers across the bulk of Applications and use-cases. Most are connection-oriented, vis-à-vis TCP. Traditionally, 'netstat' has been the de facto socket-expostion agent du jour. In more recent times, however, 'ss' has emerged and now favoured as an elevated socket-exposition agent. Know 'netstat', but also be equally amenable to the virtues of: 'ss'. Let's have a glance at 'ss' in this release.
heredoc Edition - Released
Visibly, 80-Columns of characters displayed is agreeable; certain to rightly-render. In practice, whether @ the CLI or inside of your script, strings can, and do become intractable, leading to multiple lines, reliance upon proper-escaping and the like. HereDoc, widely-implemented across environments, alleviates this concern, rendering long strings much more manageable. Use the mechanism to your advantage across your toolset.

Spend some time exploring Redis Replication in this release.
