You probably heard that side effects in programming can be harmful. This post is not about imperative versus declarative approach, though. This is about side effects you may create without paying attention to little details. Just few examples. Running process and blinking Let’s…
This is the ninth part of the Async Wandering series. For your convenience you can find other parts in the table of contents in Part 1 – Why creating Form from WinForms in unit tests breaks async? In previous part I mentioned multiple…
Word of warning: if you come to this post to find the solution only and you are not interested in the explanation how to do it then scroll down to the last section. I don’t expect any non-Polish speaker to do it so…
This is the twentieth fourth part of the .NET Inside Out series. For your convenience you can find other parts in the table of contents in Part 1 – Virtual and non-virtual calls in C# Let’s take this code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
using System; using System.Threading; using System.Threading.Tasks; public class Program { public static void Main() { Task.Factory.StartNew(Handle); } public static void Handle(){ Console.WriteLine(Thread.CurrentThread.ManagedThreadId); Task.Run(() => { Console.WriteLine(Thread.CurrentThread.ManagedThreadId); Thread.Sleep(1000); }).Wait(); } } |
and compare it…

Recently I was debugging this simple PySpark code:
|
1 2 3 |
someDataframe = ... someDict = someDataframe.collectAsMap() someOtherDataframe.filter(lambda x: x in someDict).take(1) |
First, we get some DataFrame. Next, we collect it to dictionary. It doesn’t matter how you create the dictionary, actually it could be a set or list as well. Finally, we do some filtering…
This is the twentieth second part of the .NET Inside Out series. For your convenience you can find other parts in the table of contents in Part 1 – Virtual and non-virtual calls in C# We know that a .NET application is always…
I had 3 jobs in my Redshift cluster. First of them was querying two tables A and B and then inserting data to table B. Second transaction was removing and inserting to table A. Third transaction was just reading A and B. The…

Recently I was debugging the issue with DotNetBrowser and external call from JavaScript. I had the following:
|
1 2 3 4 5 6 7 8 9 10 |
FleepBrowser.Browser.DocumentLoadedInMainFrameEvent += delegate(object sender, DotNetBrowser.Events.LoadEventArgs e) { FleepBrowser.Browser.ExecuteJavaScriptAndReturnValue("window").AsObject().SetProperty("external", new ExternalCodeHandler { NewMessagesCountCallback = delegate(int count, int allCount) { // ... } }); } |
So I configure the browser and then set external object to handle callback. The callback is a method accepting two integers. It was called using…
This is the eighteenth part of the .NET Inside Out series. For your convenience you can find other parts in the table of contents in Part 1 – Virtual and non-virtual calls in C# We saw in Part 8 — Handling Stack Overflow…
This is the third part of the Higher Kinded Types in C# series. For your convenience you can find other parts in the table of contents in Part 1 — Introduction This time we start with this invoice:

1 2 3 4 5 |
public class HeterogenousInvoice<T> where T : BrandProvider, new() { public Brand<T, string> Item1 { get; set; } public Brand<T, int> Item2 { get; set; } } |
Obviously, this breaks things…
This is the second part of the Higher Kinded Types in C# series. For your convenience you can find other parts in the table of contents in Part 1 — Introduction So now we can use invoice with items as Brand< Started, string>.…
This is the first part of the HKT series. For your convenience you can find other parts using the links below: Part 1 — Introduction Part 2 — Homogenous invoice Part 3 — Heterogenous invoice Today we will play with higher kinded types…
