Overriding conditions_for_collection from a module

When using ActiveScaffold, I had problems overriding conditions_for_collection from a module. The problem was that even tho I was overriding the instance method conditions_for_collection in the FilterFormExtensions module, I was including (using "include FilterFormExtensions") the module before inserting the activescaffold into the controller (using the active_scaffold method). Any active scaffold method that you want override using a module, make sure you include the module after inserting the active scaffold. Of course if you declare the method as an instance method of your controller, the method will be overridden regardless of whether is before or after inserting the active scaffold.

How to create online multiplayer HTML5 games in Contruct2

Construct2 can use websockets to send and receive messages between games. By using socket-io , we can use a Node.js script as the server and my modification to the socket-io plugin for Construct2 to allow the games to synchronize data between them in real-time. There are two parts to this design: the Node.js server and the Construct2 clients (the games playing). The main part of building an online multiplayer HTML5 game is to plan: how the clients will communicate how often and what to communicate how much of the logic will go into the server and how much to the client. In my sample game, I chose to have each client own a player and have the server just relay messages: Use string messages in the form TypeOfMessage, Parameter1, Paremeter2, Parater3, etc to communicate. Have the clients send their player position about 16 times a second. Whenever their player shoots, the client needs to send a message immediately. Almost all of the game logic will...

Power Automate: SFTP action "Test connection failed"

When I added an SFTP create file action to my Power Automate flow ( https://flow.microsoft.com ) , I got the following error in the action step, within the designer: "Test connection failed" To troubleshoot the Power Automate connection, I had to: go the Power Automate portal then "Data"->"Connections" the sftp connection was there, I clicked on the ellipsis, and entered the connection info It turns out, that screen provides more details about the connection error. In my case, it was complaining that "SSH host key finger-print xxx format is not supported. It must be in 'MD5' format". I had provided the sha fingerprint that WinScp shows. Instead, I needed to use the MD5 version of the fingerprint. To get that, I had to run in command line (I was in a folder that had openssh in it): ssh -o FingerprintHash=md5 mysftpsite.com To get the fingerprint in MD5 format. I took the string (without the "MD5:" part of the string) and put ...
