Windows Powershell automated CPU monitoring and services restart

konalexiou

Today I was having some trouble with a windows server. For some reason it was using a lot of CPU and then froze. I had to restart mysql, apache and sql server everytime and that only when I could logon with remote desktop. I decided to have a script check every now and then if the cpu was increased and came up with the following powershell script:

$cpuutil=(get-counter -Counter "\Processor(_Total)\% Processor Time" -SampleInterval 1 -MaxSamples 5 | select -ExpandProperty countersamples | select -ExpandProperty cookedvalue | Measure-Object -Average).average
Write-Host "CPU: $cpuutil"

If ($cpuutil -ge 90){
	Write-Host "Restarting MySQL, Apache, SQL-Server..."
	Restart-Service httpd, mysqld, sqlservr
	Exit
}

I then went and made a scheduled task fire this script every hour and everything seems to be working fine now.

Toast messages and spinners in iOS

konalexiou

I found this code while looking for an iOS notification similar to Android Toast.
The code is available in a Github project found here: https://github.com/scalessec/Toast
It was just what I needed!

P.S. You can also make great loaders with this code 😉

To install:

  1. Add a pod entry to your Podfile pod 
    pod 'Toast', '~> 3.0'
  2. Install the pod(s) by running 
    pod install
  3. Include MBProgressHUD wherever you need it with: 
    #import "Toast/UIView+Toast.h"

 

Code:

Put the following code wherever you want to invoke the toast.

[self.view makeToast:@"This is a piece of toast with a specific duration." duration:3.0];

For displaying a loader with the activityspinner use

[self.view makeToastActivity:CSToastPositionCenter];

And to hide it:

[self.view hideToastActivity];

‘Hello world’ in 20+1 different programming languages

konalexiou

Hello! Since it is my first blog post I decided to write a ‘hello world’ post with examples from different programming languages.

A hello world program is used to give the reader a quick overview of the programming language syntax and also get the code for the bare minimum program to run.

Le’ts not waste another minute and get to it.

  1. PHP 
    <?php echo "hello world!";?>
  2. Javascript 
    alert("hello world!");
  3. Python 
    print("hello world")
  4. C 
    int main(void)
{
puts("Hello, world!");
}
  5. C++ 
    #include <iostream.h>

main()
{
    cout << "Hello World!" << endl;
    return 0;
}
  6. C# 
    using System;
class Program
{
    public static void Main(string[] args)
    {
        Console.WriteLine("Hello, world!");
    }
}
  7. Objective C 
    int main(void)
{
&nbsp; &nbsp; NSLog(@"Hello, world!");
&nbsp; &nbsp; return 0;
}
  8. HTML 
    Hello World!
  9. Matlab 
    disp('Hello, world!')
  10. Java 
    
class HelloWorld {
  static public void main( String args[] ) {
    System.out.println( "Hello World!" );
  }
}
  11. MS DOS 
    
ECHO Hello World!
  12. Linux Bash 
    echo "Hello World!";
  13. Node.js 
    var sys = require('sys');
sys.puts('Hello World');
  14. Ruby 
    puts "Hello World!"
  15. BASIC 
    10 PRINT "Hello World!"
  16. Visual Basic 6 
    Private Sub Form_Load()
Print "Hello World"
End Sub
  17. Visual Basic .NET 
    Imports System.Console

Class HelloWorld

    Public Shared Sub Main()
        WriteLine("Hello, world!")
    End Sub

End Class
  18. Pascal 
    program HelloWorld(output);
begin
  WriteLn('Hello World!');
end.
  19. ASP.NET 
    <%= "Hello World!" %>
  20. Fortran 77 
    PROGRAM HELLO
PRINT*, 'Hello World!'
END
  21. Arduino 
    void setup()
{
  Serial.begin(9600);
  Serial.println("Hello, world!");
}

void loop()
{
  
}

 

When I started writing this post I was sure I would write each hello world on my own. But as the list was growing I got a bit tired and googled some of the programs. Doing that I stumpled upon a website with 533 ‘hello world’ programs http://helloworldcollection.de/
