Restarting a self-updating python script
In Linux, or any other form of unix, os.execl and friends are a good choice for this — you just need to re-exec sys.executable with the same parameters it was executed with last time (sys.argv, more or less) or any variant thereof if you need to inform your next incarnation that it’s actually a restart. … Read more
How to work with Android’s in-app update API?

How can I execute something just once per application start?
SharedPreferences seems like ugly solution to me. It’s much more neat when you use application constructor for such purposes. All you need is to use your own Application class, not default one. public class MyApp extends Application { public MyApp() { // this method fires only once per application start. // getApplicationContext returns null here … Read more
Running Microsoft Access as a Scheduled Task
To the best of my knowledge the shortest path for a Windows Scheduled Task to “do something useful in Access VBA” is: Create a Public Function (not Sub) in the database. For example: Option Compare Database Option Explicit Public Function WriteToTable1() Dim cdb As DAO.Database Set cdb = CurrentDb cdb.Execute “INSERT INTO Table1 (textCol) VALUES … Read more
How to disable Google Chrome auto update? [closed]
Have spent a long time trying to disable updates (literally hours, reading forums and testing various (some exotic) solutions), and this was driving me crazy.

Auto-update library for .NET? [closed]
ClickOnce has its own security limitations (understandbly so). If you want the full power and control of a Windows application then go with the .NET application updater component. It works like a charm and has even been used by Microsoft internally for their .NET based game (I don’t remember the game name though).
How can I write a Java application that can update itself at runtime?
The basic structure of a solution is as follows: There is a main loop responsible for repeatedly loading the latest version of the app (if required) and launching it. The application does its thing, but periodically checks the download URL. If it detects a new version it exits back to the launcher. There are a … Read more
WebView load website when online, load local file when offline
That sounds like a simple webview caching mechanism to me. The following should do what you are looking for: WebView webView = new WebView( context ); webView.getSettings().setAppCacheMaxSize( 5 * 1024 * 1024 ); // 5MB webView.getSettings().setAppCachePath( getApplicationContext().getCacheDir().getAbsolutePath() ); webView.getSettings().setAllowFileAccess( true ); webView.getSettings().setAppCacheEnabled( true ); webView.getSettings().setJavaScriptEnabled( true ); webView.getSettings().setCacheMode( WebSettings.LOAD_DEFAULT ); // load online by default … Read more
