The idea behind this modification is to add “personality” to command line, sometimes you're working with several tabs and this customization allows to quickly identify which one is the one you're looking for and have fun in the process. Two line command prompt means more space for title, current path, git status, pyvenv Includes last command status and time of execution Change context title and color Change emoji in command prompt Based on Agnoster so it includes git status, pyvenv, nodejs, aws Please take a look at the Agnoster Persona repo at GitHub Agnoster Persona repository https://www.jorgeanaya.dev/en/bin/docker-ps-prettify/ Sat, 01 Aug 2020 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/docker-ps-prettify/ Everytime I run docker ps to list my containers, I find hard to understand where does the list start and where it ends: What the! ... the port, which one? ... I almost feel like I'm seeing the matrix I have to say, after some time your eyes get used to and begin to do weird movements but at the end you begin to understand the output, of course it shouldn't be this way, so I found there are server ways to improve the command output, let's take a look. https://www.jorgeanaya.dev/en/bin/docker-network-name-is-ambiguous/ Wed, 25 Mar 2020 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/docker-network-name-is-ambiguous/ The Issue I was working on my Linux server, and I had to restart it. The docker instance was empty when the server came back, and it didn't show any container. I was in shock, and I thought I had lost my images and containers. After reviewing the system's health couldn't found a root cause, so I did a second restart 😅 and that's it the containers were back. Great! But when I tried to start my containers … https://www.jorgeanaya.dev/en/bin/react-the-simplest-app/ Sun, 02 Feb 2020 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/react-the-simplest-app/ The following code allow us to understand the way we can built a simple react app Read the comments in the code <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <meta http-equiv="X-UA-Compatible" content="ie=edge" /> <title>React JS Search Results</title> <!--Add React and Babel References --> <script src="https://unpkg.com/react@16/umd/react.development.js"></script> <script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script> <script src="https://unpkg.com/babel-standalone@6.26.0/babel.js"></script> </head> <body> <section> <!--Every React app must have what’s known as an entry point. https://www.jorgeanaya.dev/en/bin/terminal-ffmpeg-concat-videos/ Sun, 12 Jan 2020 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/terminal-ffmpeg-concat-videos/ To concatenate some videos using ffmpeg we need to provide a text file with the word file followed by the path to the media:  VideoList.txt # We can use absolute or relative paths file '/path/to/video1.mp4' file '/path/to/video2.mp4' file '/path/to/video3.mp4'  Run # If you use an absolute path to the file we need to add the parameter -safe 0 ffmpeg -f concat -safe 0 -i videolist.txt -c copy output. https://www.jorgeanaya.dev/en/bin/terminal-check-string-value/ Sun, 05 Jan 2020 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/terminal-check-string-value/ A basic task when you are scripting is to verify if a string is empty or not. We can do it using the following operators -n y -z  Check if empty #!/bin/bash VAR='' if [[ -z $VAR ]]; then echo "String is empty." fi  Check if not empty #!/bin/bash VAR='Linuxize' if [[ -n $VAR ]]; then echo "String is not empty." fi REFERENCE: Linuxize https://www.jorgeanaya.dev/en/bin/sql-ssms-sql-studio-as-remote-user-vpn/ Sun, 01 Sep 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/sql-ssms-sql-studio-as-remote-user-vpn/ Here is a tip to connect to SQL Server Management Studio using different windows credentials than the current logon, very useful when using VPN and requires using another user from another domain. The key is to create a shortcut and use the command runas with parameters /user and /netonly to which we point out the SSMS exe file at the end we add the nosplash option.  SSMS run as C:\Windows\System32\runas.exe /user:domain\username /netonly " https://www.jorgeanaya.dev/en/bin/git-reset-undo-last-commit/ Thu, 01 Aug 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/git-reset-undo-last-commit/ Sometimes we need to undo our last commit but we don't want to lose the changes we've already made. There are several reasons, sometimes we made a commit prematurely or we forgot to add a file, etc. WARNING: These commands assume we haven't sync/publish the changes to a remote origin. git reset: What it actually does is that moves the actual branch to X commit, so, using HEAD~1 or "HEAD^" (both are valid) we move the actual branch to the previous commit, example:  git reset https://www.jorgeanaya.dev/en/bin/windows-clean-recycle-bin-globally/ Sat, 20 Jul 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/windows-clean-recycle-bin-globally/ The Emergency 🔔 Notification, there is an emergency, you need to connect to a remote desktop to run some transact SQL queries, you do it, press F5 and … 💥 An error occurred while executing batch. Error message is: There is not enough space on the disk.... You realize that there isn't enough space on C - nothing, zero, nada - It turns out that SSMS needs space to write some temp files on C:\Users\. https://www.jorgeanaya.dev/en/bin/vscode-configure-remote-development-extension/ Mon, 01 Jul 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/vscode-configure-remote-development-extension/ Recently, vscode add a new extension Remote Development that allow us to connect to a remote project via SSH, Containers or WSL.

This could be useful in many scenarios (). There are two commands that we can use: subts  subts REM to create subst X: "C:\Users\LuckyDeveloper\MyFolderToMap" REM to delete subst X: /D Drive name must be followed by a whitespace If the target folder has whitespace in its name, use quotes “\directory withe white spaces" Notice that at the end of the command we don't use the character “\” ✍️ This command expects that the folder is always present, be aware of this so you don't impair the performance of your machine https://www.jorgeanaya.dev/en/bin/swift-basic-concepts-function-classes/ Thu, 07 Mar 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/swift-basic-concepts-function-classes/  Functions and Classes // Functions func grettings_void() { print("Hello World!") } func grettings() - String { return "Hello World!" } func grettings(yourname:String) - String { return "Hello \(yourname)" } func sum(a:Int,b:Int) - Int { return a + b } print(grettings_void()) print(grettings()) print(grettings(nombre: "Jorge")) print(sum(a: 2, b: 3)) // Classes class Person { var name : String var age : Int init(\_name:String, \_age:Int) { self.name = \_name self.age = \_age } func grettings() - String { return self. https://www.jorgeanaya.dev/en/bin/swift-basic-concepts-control-data/ Wed, 06 Mar 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/swift-basic-concepts-control-data/  Control and Data // Switch let numericValue = 3 switch numericValue { case 1: print("The value is 1") case 2: print("The value is 2") case 3...10: // Using ranges print("The value is greater or equal to 3 but less than 10") default: print("The value is greater than 10") } let weekDays = "Martes" switch weekDays { case "monday","wednesday","friday": print("Promo A") case "tuesday","thursday": print("Promo B") case "saturday": print("Promo C") default: print(" https://www.jorgeanaya.dev/en/bin/swift-basic-concepts-variables/ Tue, 05 Mar 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/swift-basic-concepts-variables/  Variables // Variable declaration var expressiveAssigment : String = "Value" print(expressiveAssigment) var expressive : String = "" expressive = "Value" print(expressive) var intuitive = "Guest What?" print(intuitive) // Contants let constantAssigment : String = "Constant Value" print(constantAssigment) let pi = 3.1416 print(pi) // Optionals var optionalString : String? = nil var optional : Int? = nil // How to work with optionals print(optional) // nil print(optional ?? 0) // Provide a default value print(optional as Any) // Explicit Cast to Any to avoid errors print(optional! https://www.jorgeanaya.dev/en/bin/js-jquery-find-elements-inside-a-nodelist/ Sun, 03 Feb 2019 00:00:00 +0000 https://www.jorgeanaya.dev/en/bin/js-jquery-find-elements-inside-a-nodelist/ Using jquery.find() we can find by element or selector.

A very interesting framework that uses GO Language. In my humble opinion HUGO is versatile, rewarding and fun. It has a helpful community not as big a another frameworks but enough to help you not to get stuck.
