Convert Amp to Watts
Creditos: https://www.rapidtables.com/convert/electric/1-amp-to-watt.html
You can calculate (but not convert) the watts from amps and volts:
How to convert 1 amp to watts
How to convert electric current of 1 amp (A) to electric power in watts (W).You can calculate (but not convert) the watts from amps and volts:
1A to watts calculation with voltage of 12V DC
For DC power supply, watts are equal to amps times volts.
watts = amps × volts
watts = 1A × 12V = 12W
1A to watts calculation with voltage of 120V AC
For AC power supply, watts are equal to the power factor times amps times volts.
watts = PF × amps × volts
For resistive load without inductors or capacitors, the power factor
is equal to 1:
watts = 1 × 1A × 120V = 120W
For inductive load (like induction motor), the power factor can
be approximately equal to 0.8:
watts = 0.8 × 1A × 120V = 96W
1A to watts calculation with voltage of 230V AC
For AC power supply, watts are equal to the power factor times amps times volts.
watts = PF × amps × volts
For resistive load without inductors or capacitors, the power factor
is equal to 1:
watts = 1 × 1A × 230V = 230W
For inductive load (like induction motor), the power factor can
be approximately equal to 0.8:
watts = 0.8 × 1A × 230V = 184W

[root@tecmint]# rsync -avzh /root/rpmpkgs /tmp/backups/
2- Copy/Sync Files and Directory to or From a Server
This command will sync a directory from a local machine to a remote machine. For example: There is a folder in your local computer “rpmpkgs” which contains some RPM packages and you want that local directory’s content send to a remote server, you can use following command.
Copy a Directory from Local Server to a Remote Server
[root@tecmint]$ rsync -avz rpmpkgs/ root@192.168.0.101:/home/

COMO CALCULAR LA CANTIDAD DE BLOCK
Fuente: http://todo-sobre-construccion.blogspot.com/2011/02/como-calcular-la-cantidad-de-block.html
En este artículo vas a aprender como calcular la cantidad de block que te llevaras en la construcción de un muro.
Primero que nada debes tener o más bien saber cuantos metros cuadrados de muro vas a construir, esto es fácil es solo sacar el área del muro. Por ejemplo:
tenemos 2 muros de 2.5 mts. de largo con una altura de 2 mts. por lo tanto:
Metros de muro:
A1= 2.5 x 2= 5 m2 (m2=metros cuadrados)
A2= 2.5 x 2= 5 m2
Total =10 m2
Ya teniendo los metros cuadrados de muro entonces debemos conocer el área que abarca el block contemplando la junta de mortero.
Por ejemplo para un block de 15x20x40
Son las medidas del block, el 15 te indica el espesor del block
El 20 te indica el alto del block
Y el 40 te indica el largo del block.
Por lo que si vas a construir con este block las medidas que vas a contemplar para saber cuantos blocks te vas a llevar son el largo y el alto, agregándole 1cm. De más por la junta que lleva en los costados y en la unión de las filas del block. Por lo que tenemos
A block = 0.41x0.21 =0.0861m2/pza.
Entonces divides el área total del muro entre el área del block y obtendrás el número de piezas que vas a necesitar.
Piezas= 10/0.0861 = 116.144 pzas.
Ahora lo que te falta contemplar es el porcentaje de desperdicio que se ocupa entre un 3 y un 5%.
Ahora ocupando un 5% de desperdicio tenemos:
116.144 x 1.05 = 121.95 pzas. Aproximando son 122 pzas.
Y listo tienes la cantidad de piezas a ocupar.

mod_evasive is an evasive maneuvers module for Apache to provide evasive action in the event of an HTTP DoS or DDoS attack or brute force attack. It is also designed to be a detection and network management tool, and can be easily configured to talk to ipchains, firewalls, routers, etc. mod_evasive presently reports abuses via email and syslog facilities.

Mikrotik Wan FailOver

Failover (Conmutación por error) cuando un enlace deja de funcionar por cualquier motivo y automáticamente cambia al enlace de backup o redundancia para seguir funcionando.
En este caso tendríamos dos proveedores de servicio (Por ejemplo Arnet+Fibertel), y por un X motivo el primer servicio deja de funcionar, automáticamente se redireccionara todo al servicio secundario o backup.
Configuración Funcional a partir de Mikrotik RouterOS v3.30 (Versión Actual v5.24)
Paso a Paso:
Para iniciar con la configuración correspondiente vamos a primero crear reglas de salidas de Internet en IP ► Firewall ► NAT, configuraremos las interfaces correspondientes con las direcciones IP correspondientes.
