I’ve been using Whatsapp for about 2 years now, and it was more or less OK, until I bought a new phone and tried to move my account there. This proved to be a highly non trivial excercise full of frustration. In my naïveté I just installed Whatsapp on the new phone, expecting ( Read more... )

TL;DR: wrapping existing method DoSomething(MyData data), with an identically named generic extension method DoSomething(T data) is a bad idea, since it erases compile-time type checking. DoSomething() may now be called with any type, and it may be hard to tell whether you are ( Read more... )

That means that .NET string sorting is not lexicographical, that came as a shock to me. If it were ( Read more... )

I have just spent a few fun hours fighting Apache rewrite rules in an .htaccess file. It turns out that temporary redirects just work, but permanent redirects require RewriteBase! Frankly, this is insane.

Suppose, I have my web site test.ikriv.com that lives in /var/www/html on ( Read more... )

Over the week-end I created the TaskTimer class that allows to execute code on timer in an async method:

static async Task DoStuffOnTimer() {     using (var timer = new TaskTimer(1000).Start())     {         foreach (var task in timer)         {             await task ( Read more... )

I wrote a tool called “IsItMySource” that can list source files of a binary and, more importantly, check whether particular source directory matches the binary.

The description is here: https://www.ikriv.com/dev/dotnet/IsItMySource/index.php.
