Useful redis commands (in a nutshell)

redis-cli, the Redis command line tool, is a quick shortcut for running the most common operations that require our everyday job. Let's review them in a nutshell:

To open a server session, run the console command:
shell> redis-cli -h <hostname>

The password can be specified in the above command by setting the -a <password> argument, but for security reasons it's better to authenticate once in the redis-cli console:
redis> AUTH [username] password

Again from the console, to check if one ore more keys exist:
redis> EXISTS <key> [<key> ...]

To search keys matching a given pattern:
redis> KEYS <pattern>

To get an entry value given its key:
redis> GET <key>

To delete an entry given its key:
redis> DEL <key>

To quit the redis-cli session:
redis> EXIT

Linting C# in Visual Studio Code

Though very usual in programming environments as Javascript/Typescript, linting , or analyzing code for enforcing a set of coding style rules, is not usually present in the .NET based environments. Rule enforcing is really useful when working on team shared codebases in order to keep them coherent, what in last term reduces both development times and coding errors. A linting example Maybe a practical example would be helpful for explaining what  linting  is to the newcomers (feel free to go on if you aren't). Let's imagine you are a new member in a C# development team that has well established set of coding style rules. Instead (or apart) of putting them in a document, they've adopted a tool that checks these rules during the code building process. Your first code is such ambitious as this: namespace HelloWorld {      using System;      public class Program      {           public static void Main(string[] args)           {                Console

ESlint: Ignore unused underscore variables

Some naming conventions promote the use of the underscore character (" _ ") for those variables that must be declared but are not being used. One common case is that in which a function signature contains some variables that will not be used, as for instance the Express error handlers: app.use(function(err, req, res, next) { console.error(err.stack); res.status(500).send('Something broke!'); }); In the above example only the arguments err and res are being used, though all four must be defined in the handler signature. Thus, following the naming convention of using underscores for those unused variables, we could recode it as: app.use(function(err, _, res, __) { console.error(err.stack); res.status(500).send('Something broke!'); }); Though it makes the function more readable, it comes with a problem if using ESlint: it will blame by declaring unused variables. error '_' is defined but never used error '__' is define
