Programación / Scripting / [APORTE] [BATCH] | Clean nVidia shader cache
|
en: 4 Marzo 2024, 14:30 pm
|
El siguiente Batch-script tiene la función de eliminar los archivos de cache de sombreadores de texturas generados por las tarjetas/drivers de nVidia, lo que puede solucionar fallas o errores gráficos en algunos video juegos, o simplemente lo pueden utilizar para eliminar un poco de espacio usado cuando sea necesario (a veces pueden haber gigabytes de datos de cache de shaders). Funciona para los que tengan instalados drivers recientes, y drivers no tan recientes.
:SHOW_WELCOME_SCREEN COLOR 07 ECHO:This script will perform a cleanup of the nVidia's shader cache files. ECHO:Removing the shader cache files may fix crashes or graphic errors in some video games. ECHO:Note that shader cache files that are in use cannot be deleted. CHOICE /C "YN" /M "Continue" CLS :DO_WORK REM This directory only exists prior to nVidia drivers v471.11 (IF Exist " %ProgramData%\NVIDIA\NV_Cache\*" (DEL /A /F /Q " %ProgramData%\NVIDIA\NV_Cache\*" )) || (GOTO:SHOW_ERROR_SCREEN ) REM These directories exist beginning with nVidia drivers v471.11 (IF Exist " %LocalAppData%\NVIDIA\DXCache\*" (DEL /A /F /Q " %LocalAppData%\NVIDIA\DXCache\*" )) || (GOTO:SHOW_ERROR_SCREEN ) (IF Exist " %LocalAppData%\NVIDIA\GLCache\*" (DEL /A /F /Q " %LocalAppData%\NVIDIA\GLCache\*" )) || (GOTO:SHOW_ERROR_SCREEN ) :SHOW_GOODBYE_SCREEN COLOR 0A :SHOW_ERROR_SCREEN COLOR 0C ECHO:ERROR DETECTED.

muy bien indentado y ordenado el código, bien legible. ¡Que va!, te agradezco los elogios pero con la honestidad y la humildad por delante me veo obligado a hacer un pequeño inciso para abordar tu comentario, ya que precisamente este es el código peor estructurado en comparación con los demás scripts de PowerShell que he compartido estos días. No he aplicado ninguna mecánica de encapsulación o modularidad para dividir el código fuente en partes más pequeñas y autónomas como funciones que realicen tareas específicas, tampoco he añadido lineas separatorias ni documentación o comentarios explicativos al código ...más allá de lo que se imprime en la "pantalla de bienvenida". Es un código que hice rápido (pero sin cometer errores de lógica) y harto de tener que escribir el comando de DISM en la CMD. Al final tantas líneas de código se basan en una simple ejecución "controlada" del proceso DISM (y en la creación automatizada del directorio donde guardar los drivers), por lo que es algo muy simple y no me voy a esmerar más en adornar y estructurar este código. Pero te lo agradezco, de nuevo.
los creas con el idioma inglés y es así como debería ser con un idioma universal y porque tenés la idea y propósito de que tus programas y códigos sean usados en todo el mundo por personas de todos los idiomas. Totalmente de acuerdo. Programar con la intención de compartir tu creación para que (quizás, con suerte) le pueda servir a otras personas, y hacerlo en Español u otros idiomas que no sean el Inglés (y ya ni hablemos de hacerlo en Catalán, Euskera o Gallego), solo sirve para imponerse límites absurdos de comunicación a uno mismo y cerrarse las puertas de la visibilidad a nivel mundial. Y si uno no domina suficientemente el Inglés, al menos debería intentarlo con un traductor online. Aunque el Español es el segundo idioma más hablado del mundo, después del chino. Creo que todavía sigue siendo así. Pero en la práctica todo se transmite en Inglés... Yo a veces me encuentro códigos de programadores asiáticos que claramente han recurrido a usar un traductor como Google Translate para escribir todos los comentarios del código fuente y las cadenas de texto de variables y etc, y la traducción suele ser una porquería, pero sin duda alguna se agradece que estén en Inglés por que medio se entiende todo bien, y si esos códigos estuvieran escritos en chino mandarín probablemente no lograrían captar la atención (o al menos la mía no, desde luego) y por lo tanto no podrían llegar a alcanzar una visibilidad y utilidad a nivel global, por que la mayoría al ver algo escrito en chino simplemente lo acabaríamos ignorando al primer vistazo. Me pasa mucho con los códigos en ruso también. Yo no voy a hacer la labor de traducir algo que el autor no ha traducido al Inglés. Me indigna un poco, lo reconozco xD por que considero que decidir programar en Inglés o hacerlo en Español no se puede reducir a un debate de preferencias personales. Ni siquiera en el ámbito privado. ¡Ni mucho menos que los profesores enseñen a programar en Español!. Pero bueno, esto es solamente mi opinión personal. Entiendo que habrán defensores de la idea de programar en el idioma que a uno le de la gana, de programar con el idioma con el que uno se sienta más a gusto o incluso con el que mejor se identifique, y lo respeto, pero no comparto ese pensamiento. Yo sostengo la idea de que programar basándose en preferencias lingüisticas que sean excluyentes del Inglés, o basándose en identitarismos nacionalistas absurdos (Catalán, Euskera, Gallego, etc) no aporta ni un solo beneficio en la vida real (más allá de que te puedan pedir programar en cierto idioma o dialecto como requisito para trabajar como funcionario en algo relacionado con la programación o la informática en general). ¡Un saludo!.

Programación / Scripting / [APORTE] [PowerShell] Truncate Log Files
|

El siguiente script desarrollado en PowerShell sirve para truncar el tamaño, a cero bytes, de los archivos log (*.log) dentro del directorio actual y subdirectorios. También se puede usar desde el directorio raiz "C:\", por ejemplo. Es simplemente una herramienta de limpieza ocasional. En herramientas de limpieza como CCleaner se puede especificar una regla para buscar y eliminar archivos log, sin embargo, si el archivo está en uso, este tipo de herramientas no lo podrá eliminar. En cambio, la metodología empleada en este script se beneficiará de cualquier archivo en uso que comparta permisos de escritura para poder borrar su contenido sin llegar a eliminar el archivo en simismo. <# =========================================================================================== | | | .NET Code | | | =========================================================================================== #> $netCode = @' Option Strict On Option Explicit On Option Infer Off Imports System Imports System.Runtime.InteropServices Imports System.Text Public Class FileUtils Public Shared Function FormatFileSize(fileSize As Long) As String Dim buffer As New StringBuilder(16) NativeMethods.StrFormatByteSize(fileSize, buffer, buffer.MaxCapacity) Return buffer.ToString() End Function End Class Friend NotInheritable Class NativeMethods <DllImport("Shlwapi.dll", CharSet:=CharSet.Auto)> Friend Shared Function StrFormatByteSize(fileSize As Long, <MarshalAs(UnmanagedType.LPTStr)> buffer As StringBuilder, bufferSize As Integer) As Long End Function End Class '@ $netType = Add-Type -TypeDefinition $netCode ` -CodeDomProvider (New-Object Microsoft.VisualBasic.VBCodeProvider) ` -PassThru ` -ReferencedAssemblies "System.dll" ` | where { $_.IsPublic } <# =========================================================================================== | | | Functions | | | =========================================================================================== #> function Show-WelcomeScreen { Clear-Host Write-Output "" Write-Output " $($host.ui.RawUI.WindowTitle)" Write-Output " +==========================================================+" Write-Output " | |" Write-Output " | This script will search for log files (*.log) inside the |" Write-Output " | current working directory (including subdirectories) to |" Write-Output " | truncate them by setting their length to zero. |" Write-Output " | |" Write-Output " | This may be useful to help reduce the size of a system |" Write-Output " | full of heavy sized log files. |" Write-Output " | |" Write-Output " +==========================================================+" Write-Output "" } function Confirm-Continue { Write-Output " Press 'Y' key to continue or 'N' to exit."

El siguiente script desarrollado en PowerShell y dependiente del programa externo RAR.exe (WinRAR), sirve para comprimir cada archivo dentro del directorio actual de forma individual, con compresión máxima, y utilizando los tamaños de diccionario especificados. La sección "Variables" dentro del script permite configurar varias cosas, entre ellas: - Los tamaños de diccionario. - Las extensiones de archivo que se deben procesar sin aplicar compresión. - Preservar solamente el archivo RAR generado con el menor tamaño de todos. (eliminar los archivos RAR de mayor tamaño) - Especificar una diferencia de tamaño (tolerancia) arbitraria para eliminar archivos RAR generados (con mayores tamaños de diccionario) de un tamaño de archivo similar. - Enviar los archivos RAR eliminados a la papelera de reciclaje. Es muy útil, por ejemplo, para comprimir de forma automatizada archivos ISO de consolas, y obtener así el mejor resultado entre Tamaño de diccionario / Tamaño de archivo.

(eliminar los archivos RAR de mayor tamaño) - Especificar una diferencia de tamaño (tolerancia) arbitraria para eliminar archivos RAR generados (con mayores tamaños de diccionario) de un tamaño de archivo similar. - Enviar los archivos RAR eliminados a la papelera de reciclaje. Es muy útil, por ejemplo, para comprimir de forma automatizada directorios de video juegos para PC y obtener así el mejor resultado entre Tamaño de diccionario / Tamaño de archivo.

Programación / .NET (C#, VB.NET, ASP) / Re: crear / compilar en windows - ejecutar en linux

¿A estas alturas de la vida? A estas alturas de la vida, Xamarin sigue sin ofrecer soporte para programar directamente en el lenguaje VB.NET, por ejemplo. Y creo que con la tecnología multiplataforma .NET MAUI sucede lo mismo. Hay cosas que simplemente no tienen la suficiente demanda o no les da la gana realizar el trabajo necesario para ofrecer soporte...
Respondiendo a tu duda principal y hasta donde yo se, ya lo respondí en mi aterior comentario pero lo diré de otra forma: no es posible desarrollar una aplicación de escritorio basada en Windows Forms de .NET Core y que sea compatible con Linux. Al menos no de forma nativa sin recurrir a Wine o cosas similares. Aténtamente, Elektro.

Hola. Abro este hilo por que he descubierto que al intentar publicar un post con el siguiente código escrito en el lenguaje Powershell: $rarExecutablePath = "$ {env:ProgramFiles}\WinRAR\rar.exe" (Nótese el espacio en blanco que he tenido que poner en la cadena " $ {env" para poder publicar este post.) Me redirige a una página con el siguiente mensaje: Web Application Firewall (WAF) Blocked Una regla de seguridad ha sido aplicada. Si crees que es un error (falso positivo) contacta con webmaster@elhacker.net - Gracias. The action you just performed triggered the security solution. If you think is false positive please contact to webmaster@elhacker.net - Thank you No se si tendrá solución, simplemente lo comunico por si pudieran hacer algo con ello. PD: Si no mando un e-mail a webmaster@elhacker.net es por que tal vez mi cuenta de correo esté bloqueada. Aténtamente, Elektro.
